Scaffold refers to various supports erected on the construction site for workers to operate and solve vertical and horizontal transportation. Scaffolds are usually made of bamboo, wood, steel or synthetic materials. Scaffolding is also used as a formwork for some projects, and is also widely used in advertising, municipal, transportation, roads and Bridges, mining and other sectors. Scaffold is divided into door type scaffold, bowl buckle type scaffold, common fastener type scaffold according to the way of connection. Common fastener scaffold is connected to the vertical pipe through the plug connected in the horizontal pipe inserted in the wheel buckle connected in the vertical pipe, to achieve the connection between the vertical pipe and the horizontal pipe.
The existing scaffolds use extended stationary scaffolding coupler in the form of a universal shaft for the purpose of mounting diversity. Although this kind of scaffolding coupler is practical, its stability is poor and Angle deflection is easy to occur. However, in some fields such as stage construction and billboard construction where the installation Angle, aesthetics and stability of scaffolding are high, most of the scaffold extension and fixed connectors cannot be met.
Scaffolding coupler is a generic term in the architecture world. It refers to the construction site used in the external wall, internal decoration or high floor where direct construction is impossible. This is mainly for the construction personnel up and down work or external safety net envelope and overhead installation components to put it bluntly is to build shelves.
Scaffolding coupler includes scaffolding and crossbar. The main body of the scaffolding coupler consists of a connecting cylinder and a clamping cylinder. The connecting cylinder is six, and the tail of the six connecting cylinders is a whole. The orientation of each connection barrel is the six axial directions of the space respectively, that is, the front, back, left and right up and down orientation of the connection center of the six connection barrels. The scaffolding coupler ‘s clamping cylinder is a hollow straight cylinder with three circular clips inside. Each clip is provided with a welded second clip, and the cylinder wall of the connecting cylinder is provided with three bolt holes. The second clip is threaded into three bolt holes on the wall of the connecting cylinder. The rear end of the clamping cylinder is closed. A socket is arranged on the pole. The receptacle is a set of cylindrical parts on the riser. The socket is provided with a plug along its circumference. The plug is a convex block with a narrow top and a narrow bottom, a narrow outside and a thin inside. The crossbar is provided with a socket that matches the shape of the plug. The socket is provided with threads. Compared with the existing technology, the scaffolding coupler is simple, plug and play, practical and reliable, convenient for the installation and disassembly of scaffolding, and the scaffold structure is solid.
Ringlock scaffolding refers to a variety of scaffolds for workers to operate and solve the vertical and horizontal transportation on the construction site. The existing ringlock scaffolding is often used to fix the steel pipe together in the process of construction. When using the ringlock scaffolding, bolts should be used to fix the steel pipe. After the bolts are used for a long time, they are prone to rust.
1. A kind of ringlock scaffolding used for construction engineering
2. The usage of above structure
3. Improve the use effect of scaffold support structure for construction
There is a kind of ringlock scaffolding used for construction engineering, including base, vertical and horizontal support rod. A chain fixing ring is arranged on the outer wall of the base. A fixed chain is arranged on the chain fixing ring, and a connecting fixing pin is arranged on the fixed chain. At least two vertical support rods are arranged vertically above the base. A sliding fixing sleeve is arranged between the upper and lower vertical support rods, and an upper connection seat is arranged at the top of the vertical support rod of ringlock scaffolding above. A horizontal support rod is arranged between two adjacent connection seats, and a trampling net plate is arranged above the horizontal support rod. The vertical supporting rod of ringlock scaffolding includes main rod body and square connector. Beneficial effect is in: first, the scaffold connection through the square pipe nesting and pin shaft fixed, simple and convenient connection, improve the construction and disassembly speed. Second, ringlock scaffolding is made of steel structure, with high support strength and modular design, which is convenient for production and transportation.
In the above structure, when used, the vertical support rod is inserted on the base and fixed with the connection fixed pin of ringlock scaffolding, and then the number of vertically fixed support rods is rotated according to the need. The square joints on the upper and lower adjacent vertical support rods are nested in the inner card slot and fixed by the connecting fixing pin. Then, the upper connecting seat and the horizontal supporting rod are fixed at the top of the vertical supporting rod of ringlock scaffolding to complete the laying of the scaffold by clamping the trampling net plate between the two horizontal supporting rods.
In order to further improve the use effect of scaffold support structure for construction engineering, the single length of ringlock scaffolding vertical support rod shall not exceed one meter. The main rod body is made of round or square steel pipe. The square joint is welded at both ends of the main rod body. The sides of the two square joints are in the same plane. The pin joint hole is formed on the square joint.
In order to further improve the use effect of the scaffold supporting structure for construction engineering, the sliding fixing sleeve is sliding connected to the external wall of the vertical supporting rod. The limit guard edge of ringlock scaffolding is welded at the upper end of the sliding fixing sleeve. The internal through-hole of the limit guard is smaller than the cross section of the square connector. The inner card groove is molded inside the sliding fixing sleeve. The inner card slot is a square hole. The square joint is sliding connected inside the inner card slot.
Traditionally, scaffolding is a temporary structure used in the construction or maintenance of buildings to support personnel and materials. Scaffolding allows a builder or repairman to stand on a raised surface. This surface allows him/her access to the raised area of the building where work is required.
1. The old ringlock scaffold system
2. The main purpose of the new ringlock scaffold system
3. An improved ringlock scaffolding system
The ringlock scaffolding system is composed of a variety of prefabricated materials connected by the scaffold connection system. Some existing scaffold connection systems use the ringlock scaffolding system to interconnect the poles and rails of scaffolding, as well as the poles and slants. The existing ringlock scaffolding system USES wedges to lock the scaffolding's risers, crossbars, and slants into place.There is such a ringlock scaffolding system. It comprises a vertical tubular column fixed at regular intervals by a disc-shaped metal rosette. The ringlock scaffolding has an expansion recess at each of the lateral edges of the first opening that extends essentially in a radial direction. The expansion concave is tapered on the removed outer surface, but the ringlock scaffolding does not contain any information about the device used to improve the rotary stiffness of the joints formed by horizontal and vertical tubular scaffold columns.
Therefore, the main purpose of the new ringlock scaffold system is to provide an improved ringlock scaffold system for connecting tubular horizontal components and vertical components with increased rotary stiffness. In addition, the required improved ring lock system will be able to create a greater contact area with the wedge and thus prevent the wedge from deflecting when using the assembled structure. In addition, the required ringlock scaffolding will significantly improve the shear load capacity.
Next, we introduce an improved ringlock scaffolding system for scaffold systems. The ringlock scaffolding system provides improved strength and rotational stiffness for connectors formed by connecting risers and crossbars, as well as risers and slants. The annular support structure has a top surface, a bottom surface and an opening extending from the top surface to the bottom surface. The inner wall of the opening in the annular support structure gradually shrinks from the top surface to the bottom surface. The receding inner wall of the opening in the annular support structure matches the cone on the surface of the wedge, thus providing a larger contact area with the receding wedge when engaged. The annular support structure provides improved strength at the joints formed between the pole and the crossbar and between the pole and the diagonal members. The annular support structure provides better rotational stiffness at the joints formed between the vertical and horizontal poles and between the vertical and diagonal members. The receding inner wall of the ring support structure is formed by forging. This significantly improves the material properties of the ring support structure. In addition, the shrinking inner wall of ringlock scaffolding's ring support structure increases the shear load capacity. The wedges used to connect the vertical and horizontal poles and the vertical and diagonal members are also forged. This provides excellent material strength and increased shear load capacity. The cast end of the bar was redesigned to support the wedge. Thus, the ability of the wedge to transfer loads from the connecting transverse, vertical and diagonal members is improved.
Frame scaffolding plays an important role in the construction industry, bringing great convenience to people's lives. But most people don't understand it. What is more clear, how should we use frame scaffolding safely?
What is the use of frame scaffolding?
What are the advantages of frame scaffolding?
How to safely use frame scaffolding
Frame scaffolding or A-frame scaffolding is versatile and easy to erect, allowing several layers to be built. Frame scaffolding or brick scaffolding is a common industry term referring to popular frames and scaffolding.
This is the most common type of scaffolding used by all types of contractors, from carpenters and bricklayers to homeowners of weekend projects. It's easy to set up and remove, allowing you to reach the height you need quickly. It is the preferred support for all types of construction work.
The tubular metal falsework system is probably one of the most commonly used bracket systems in the construction industry. The bracket consists of a welded steel or aluminum frame that is attached to the frame by cross braces to support the bracket plate or other bracket platform system.
The frame is manufactured in a variety of sizes and configurations, the most common being the standard 5 ft x 5 ft frame and walk-in arch or arched frame.
Arched frame scaffolding is very common in the field of masonry because it allows for easy movement between frames for material distribution. Brackets or side brackets can be mounted on the sides of the brackets and have different heights to provide a convenient platform for personnel on the working face of the building.
The frame scaffolding is light weight - ultra-fast erect - can be installed by one person - it is prefabricated! - All of this saves you time and money.
Builders like to use scaffolding because there is no standard between bricklayers and walls. Make full use of the wall. Frame scaffolding is not for use only by builders; many industries also benefit from the great features of scaffolding.
Framed scaffolding is the most common type of scaffolding because they are versatile, economical and easy to use. They are often used by residential contractors, painters, etc. for one or two floors, but their modular frames can also be stacked several times for large construction work.
A stable structure cannot be built on the basis of not starting a square and level. OSHA's standards are specifically tailored to the steps that must be taken to ensure a stable base.
In order to control the risk of falsework falling or collapsing, employers must ensure that scaffolding is built within the OSHA standard and is related to strength and structural integrity.
Workers are the most vulnerable to falling down when climbing or leaving the frame scaffolding. Therefore, employers must provide safe scaffolding access. Due to the incomplete state of the scaffolding, the installer and disassembler face additional access problems. The requirements to prevent falls only for these workers are described separately below.
The danger of the number one Scaffolding is that workers fall. Fall protection consists of a personal fall arrest system or guardrail system and must be provided on any scaffolding 10 feet or more below the lower level. The specific requirements are as follows. Note: Unless otherwise stated, these requirements also apply to manual propulsion pump sockets, ladder jacks, tubes and couplers, rod brackets, and special brackets as described in the Support Bracket Module.
In addition to being used only as a walkway, the platform is the working area of the Scaffolding. Therefore, inspection of the scaffolding platform requires a security check of the platform structure and how the staff uses the platform.
Two sets of ties that connect to the walls of the building help keep the stand upright.
Once the falsework is built, even if it meets all other criteria related to foundation, structure, capacity, etc., if it does not remain upright, it will still not provide a safe working platform. As a general rule, once the height of the scaffold is four times its minimum base size, even if it is plumb and square, the scaffolding becomes inherently unstable. Damage to extreme weather or structural components can also affect the stability of the scaffolding.
Because they may be built close to overhead power lines, and because they are usually made of metal, frame scaffolding may put workers at risk of electric shock. This risk can be eliminated through proper cleaning and maintenance.
Staff training and qualified personnel
Critical to the safety of Scaffolding is the use of qualified personnel to design, install/remove and maintain scaffolding, and trained workers to use them. Therefore, the evaluator's ability should be part of all stages of scaffolding inspection.

Scaffolding purchase guide:
What factors affect the price of using scaffolding?
How do you compare quotations to get a better deal?
Scaffolding is defined as an elevated temporary work platform, a flexible system of steel rods and walking boards that allows merchants to work safely aloft around the building. It is often used outdoors, but can also be used for interior decoration; For example, when trying to enter a vaulted ceiling.
Scaffolding usually provides ladders and handrails as standard and has specialized equipment to work in difficult Spaces, such as narrow alleys or Bridges over greenhouses. Multiple levels can be incorporated into the scaffolding system, but each lift and level increases the price.
The application range of Frame scaffolding is wide and varied, which is suitable for many working purposes. Various USES include:
Initial construction of the building
Exterior, interior and ceiling decoration works
Roofing installation, upgrade and repair
Restoration of historic buildings and art or sculpture
Wash the window
The window to replace
Coating and sealing
General construction, interior and exterior painting, window cleaning and roofing are the normal applications of today's framework scaffolding solutions. The selection criteria for these areas are based on the varying degrees of uniqueness required for each job. For example, roofing scaffolding requires scaffolding functions to perform roofing work. However, certain climates and working conditions narrow the options. This concept applies to all applications of frame scaffold. A basic understanding of scaffolding is necessary as additional features selected appropriately are evaluated.
Examples of climate and environmental considerations are:
Freezing temperature - platform material with low smoothness under freezing conditions
Storms - climates with a high chance of lightning should use less metal
Natural disasters - tornado weather requires additional safe treatment options
While the rules for the use of frame scaffold vary from place to place, most Frame scaffolding systems should be erected, regularly inspected and dismantled under the supervision of a trained scaffold contractor or designer.
1.High quality and durable scaffold material. The first priority should be your safety and that of others who may be using scaffolding. Inspect scaffold material to determine if it is made of high quality to ensure its reliability and durability. Therefore, you need to look for durable materials. Also, check that it has the right safety features, such as lockable wheels and anti-skid platforms. If you are tempted by the lowest price tag option, it may also indicate that it does not meet the required quality and/or standards.
2. Technical assistance. In fact, it can give you a sense of comfort when you know you have some technical help after you buy the product. Therefore, when you make up your mind about scaffolding products, ask what kind of technical support you will receive in the event of a technical failure. The advantage of technical support is one of the main reasons to buy locally, as you know assistance is just a phone call.
3. Assemble effortlessly. Now that you've chosen the scaffolding product carefully, how do you feel when you find it difficult to assemble, which is actually the last thing you need when trying to move the project forward. From now on, it is critical to choose a scaffold product with clear instructions and assemble it effortlessly, as this makes the whole process easier.
4. Repair. A simple way to determine if you are getting a high quality scaffold product is to ask about the warranty to find out what kind of warranty the company is offering to prove its confidence in the product. Check that scaffolding provides proper warranty for all parts. Well, if you're running a company that offers no guarantees at all or a very limited one, you might be wary of going elsewhere.
During the standard employment period of scaffolding industry, you should provide a fixed amount of time between two Saturdays and eight days. If the work is expected to take longer, you may need to pay an additional weekly rental.
Not surprisingly, the higher the scaffolding you need, the higher the cost. Other factors are also attributed to high costs, including the need to narrow alleys or lay foundations on public land.
Location can have a huge impact on prices, with prices in London almost three times higher than in remote parts of Scotland.
The higher the level of walking you need, the higher the cost of scaffolding. If you only work on the chimney or roof, you may only need an elevator and walk level. However, if your house is painted, you may need two or more sidewalks.
Restrict public access. In some cases scaffolding must be erected on public roads or pavements. In this case, you must obtain a license from your local council, which can be expensive.
The easiest way to build scaffolding is to go straight up from a flat base station on private land. However, sometimes special requirements are required. These include gaps that must be crossed over driveways, greenhouses or passageways. It's not hard when you have specialized equipment, but it costs more.
Another important aspect of scaffolding rental costs is site accessibility. The cheapest offer will be when scaffolding folds the frame together quickly and easily. However, if there is no passageway, for example, everything has to go through the house, the whole project will cost more.
When you are paying large sums of money for work, you must collect at least three quotations before deciding on a contractor. The following example shows the average price for several scenarios to help you determine if the offer is reasonable.
Generally speaking, scaffolding prefers large work, and you shouldn't expect a small project to be very cheap. If you need to fix drains or replace a few roof tiles, you may just need a vertical tower. Outside London, you can expect prices to be between £250 and £300, with the capital averaging £300 to £400.
Sometimes you need special equipment to get into areas with poor access. For example, you might need to erect a bridge on top of a greenhouse to reach the outside of your home. Costs range from £400 to £550 due to equipment and the extra time required, with London rising to between £650 and £700.
Cracked and unstable stacks of chimneys usually require repair work, and while you don't need to wrap the whole house, you need to get into the chimney and secure it. This means scaling the height of your home and then wrapping all four sides of the stack. In London, expect to pay up to £900 and down to £750. The cost is cheaper elsewhere, at between £550 and £750.
When you finish the roof work, you usually need to design the scaffolding structure carefully, and you need to wrap three sides of your property in the scaffolding. It will cost between £650 and £850 to install the steel structure to gutter height and provide lifts and a walkway level. If you were in London, it would be £1,100 higher. You should keep in mind that if additional levels are required, the cost will be higher.
Frame scaffolding may be expensive and is critical in the construction industry. But if you know a suitable supplier of frame scaffolding at a more affordable price,you can know the most important information about frame scaffolding . Nanjing Tuopeng's construction technology will provide you with ideal products.

Common types of frame scaffolding
What's the use of mason frame scaffolding?
What are the advantages of mason frame scaffolding?
Frame scaffolding is one of the most common types of scaffolding on construction sites worldwide. Usually made of circular pipes, the framework scaffolding comes in several different configurations, from the section containing ladders and walk-in portals to the full walkthrough section and ladder-like sections. A typical way to construct a frame scaffold is to use two sections of the frame of a scaffold connected by two intersecting sections of a support rod arranged in a square construction. Workers usually assemble scaffolds by climbing these parts, as they carry the next frame and pole parts. They then assemble the new parts that were built in the previous section.
A pin rising from a corner of a portion of a frame scaffold is fitted to a bottom recess of a corner pole of the portion, and the recess is stacked on top of the lower portion. Pin clips are placed by connection to prevent partial separation. Place plates or aluminum decking on the finished frame scaffold portion to provide a standing position for workers when assembling the next portion of the scaffold. The bottom portion of the frame scaffold is usually arranged on a threaded bracket including a large wing adjusting nut. Adjust and level the scaffold by turning these adjusting nuts until the desired inclination or level is reached.
Tubular metal frame scaffolding system is probably one of the most commonly used scaffolding systems in the construction industry. The bracket consists of a welded steel or aluminum frame connected to the frame by cross bracing to support the bracket plate or other bracket platform system.
The frames are manufactured in a variety of sizes and configurations, the most common being standard 5 'x 5' frames and walk-in or vaulted frames
Vaulted frame scaffolding is very common in masonry because it allows easy movement between frames for material distribution. The bracket or side bracket can be mounted on the side of the bracket with different heights to provide a convenient personnel platform on the working face of the building.
Mason frame scaffolding is a common industry term that refers to our popular frame and support scaffolding. Contractors of all types, from carpenters and masons to weekend project owners, use the most common scaffolding to make bricks or bricks safer and more efficient. It is easy to install and remove, allowing you to reach the desired height quickly.
Mason frame scaffolding is generally used for masonry. They are typically used by one - or two-story residential contractors, painters, etc., but their modular frames can also be stacked multiple times in large building projects. In the mason frame scaffolding, there are two standard frames, 1.5 meters away from the first standard. Mason frame scaffolding is completely independent of the stone walls.
Mason frame scaffolding is used to carry heavy loads because of the heavy weight on the stones. Therefore, by placing the standard at a fairly close distance, the stonemason frame scaffolding is made stronger.
Mason frame scaffolding consists of two ladders, two pairs of crossbars and four connecting pins.
Frame scaffolding is easy to assemble and remove, saving time and energy.
Workers can climb ladders smoothly and safely without the need for additional ladders.
Trapezoidal mason frame scaffolding is especially suitable for brick construction, exterior wall painting or plastering works. It is easy to operate and can be moved with casters.
There are many USES and advantages of mason's frame scaffolding, so it is necessary to know how to use it safely and choose a standard scaffold，If you need a well-tested, sturdy, high quality mason frame scaffolding, Nanjing Tuopeng Construction Technology can provide you with the perfect product.
