[0004] At present, the fasteners used for scaffolding in China are mainly composed of cast iron clamps and fastening steel bolts, and the friction generated by tightening the bolts forms a constraint mechanism. Its characteristics are: first, the horizontal bar and the vertical bar are overlapped on different surfaces. After the load is applied, the vertical bar is compressed downward by the extrusion force, causing the horizontal bar to bend, increasing the internal force of the horizontal bar, which is not conducive to the overall force and stability of the scaffolding; secondly, the bolts are easily corroded, resulting in difficulties in installation and disassembly, and it is easy to cause thread slippage and insufficient friction between the steel pipe and the fasteners, which poses a safety hazard; thirdly, the tightness of the bolts needs to be adjusted every time they are installed and disassembled, and the installation and disassembly workload is extremely large; finally, when the scaffolding is dismantled, after the horizontal bar is dismantled, the horizontal constraint of the vertical bar is reduced, resulting in a decrease in the stability of the vertical bar to be dismantled, often causing the vertical bar to bend, deform, and be damaged, and there are safety hazards.

Since the longitudinal horizontal bars and transverse horizontal bars of the scaffolding steel pipe are connected to the columns through the horizontal node composite connection assembly in their own same facade, the disadvantage of the prior art that the longitudinal horizontal bars and transverse horizontal bars are not in the same facade when they are connected to the columns can be eliminated, and the lateral bending force on the columns that are not in the same facade can be effectively eliminated, thereby achieving the purpose of improving the force effect.

A mounting hole 15 extending vertically is provided at the geometric center of the horizontal node composite connection assembly. The two joints 5 of the column node connection assembly are composed of the upper and lower ends of the vertical node connection shaft 7 extending out of the drum-shaped shell 4. The outer diameters of the upper and lower ends of the vertical node connection shaft 7 are adapted to the inner diameter of the column 1, and the diameter of the mounting hole is 1.2 times the diameter of the through hole provided on the top and bottom sides of the drum-shaped shell; the vertical node connection shaft 7 inserted into the mounting hole 15 and the through hole 14 is movably hinged to the horizontal node composite connection assembly in the drum-shaped shell 4 with the cooperation of the vertical quick-release connector group, and the upper and lower ends of the vertical node connection shaft 7 are respectively inserted into the inner holes of the upper and lower columns 1 and are locked and connected with the cooperation of the vertical quick-release connector group. The horizontal node composite connection assembly of the present application at least includes a transverse axis 11, a longitudinal axis 12 and a node complex 13, the mounting hole 15 is vertically arranged at the geometric center of the node complex, the transverse axis 11 and the longitudinal axis 12 are respectively distributed on the node complex 13 symmetrically along the circumferential direction through their respective ends, the transverse axis 11 and the longitudinal axis 12 respectively extend out of the adjustment long hole 6 on the corresponding side of the drum shell 4 through their respective other ends, the elastic reset components of the reset protection shell structure are respectively correspondingly connected between the drum shell 4 and the node complex 13 at the corresponding positions, and the four joints 5 of the horizontal node composite connection assembly are respectively composed of the ends of the transverse axis 11 and the longitudinal axis 12 extending out of the adjustment long hole 6 on the corresponding side of the drum shell 4; during the erection of the main node of the scaffolding, the end of the transverse axis 11 extending out of the corresponding adjustment long hole 6 can be detachably inserted in the inner hole of the corresponding transverse horizontal rod 2, and the end of the longitudinal axis 12 extending out of the corresponding adjustment long hole 6 can be detachably inserted in the inner hole of the corresponding longitudinal horizontal rod 3.

[0021] More specifically, the vertical quick-release connecting component group of the present application includes two vertical shaft clamping rings 8 and two latch pins 9. Latch holes 10 are respectively arranged on the upper and lower ends of the vertical node connecting shaft 7, and latch holes 10 are also arranged at the ends of each column 1. The vertical node connecting shaft 7 inserted into the mounting hole and the through hole is movably arranged on the horizontal node composite connecting assembly in the drum-shaped shell 4 through the two vertical shaft clamping rings 8.

The horizontal node composite connection assembly also includes a horizontal quick-release connector group consisting of four horizontal axis clamps 16 and four latches 9. Latch holes 10 are also provided on the four joints 5 of the horizontal node composite connection assembly and the corresponding horizontal horizontal bars 2 and the corresponding longitudinal horizontal bars 3; during the erection of the main node of the scaffold, the lengths of the horizontal axis 11 and the longitudinal axis 12 inserted into the corresponding horizontal horizontal bars 2 and the corresponding longitudinal horizontal bars 3 are limited by the horizontal axis clamps 16, and the detachable connection is formed as a whole under the cooperation of the latches 9 and the corresponding latch holes 10. At this time, the preferred structure is that the horizontal axis 11 and the longitudinal axis 12 are an integral structure with the node complex 13. In this way, by further improving the column node connection assembly and the horizontal node composite connection assembly, the technical problems in the prior art that the overall force of the scaffold is complex during use when conventional fasteners are used, the workload of fastener anti-corrosion maintenance is large, the friction between the fasteners and the steel pipe is difficult to determine whether it meets the standard, the workload of installation and disassembly is large, and the safety hazards during the dismantling process are large are also solved. By optimizing the main node fasteners of the scaffolding and allowing the horizontal rods of the main nodes to rotate appropriately, the internal stress on the horizontal rods is eliminated or reduced, thereby increasing the overall stability of the scaffolding. In addition, the bolt fastening connection of conventional fasteners is changed to a butt pin fastening method, which is convenient for installation and removal, eliminates the anti-corrosion maintenance work of the bolt parts, and reduces the overall workload of the scaffolding.

[0022] In summary, the technical solution provided by this application also has the following advantages:

[0023] 1. By optimizing the fastener structure, the forces on the scaffolding uprights and crossbars are located in the same plane, reducing the internal stress of the horizontal bars, preventing the bending of the horizontal bars and the overall deformation of the scaffolding, enhancing the overall stability of the scaffolding and the life of the steel pipes, improving the safety of the scaffolding and saving costs.

[0024] 2. The fasteners and steel pipes are fixed by pins, which is faster than the bolt-fastened connection of conventional fasteners, allowing the scaffolding to be installed and disassembled quickly. At the same time, it eliminates the anti-corrosion and maintenance work of the bolt parts, reduces the overall workload of the scaffolding, saves a lot of labor and material costs, and thus reduces the cost of using the scaffolding.

[0025] 3. The butt pin fastening method is adopted to prevent the conventional fastener bolts (threads) from slipping and insufficient tightening force, eliminating the safety hazards during the erection, use and dismantling of the scaffolding.

[0026] 4. By optimizing the fasteners, the control of the lateral spacing, longitudinal spacing, and step distance (vertical spacing) of the scaffolding is more convenient. The scaffolding can be designed in advance according to the specifications and the materials can be cut in a centralized and unified manner, which is conducive to the unified processing and classified stacking of scaffolding steel pipes, and is conducive to the acceptance, erection and dismantling of the scaffolding, saving construction time and costs.

[0027] The technical solution of the present application is further described below through specific embodiments:

[0028] The fasteners currently used for scaffolding can only be used for overlapping horizontal bars and vertical bars with different surfaces. After bearing the load, the internal stress of the horizontal bars is increased, which is not conducive to the overall and stable stress of the scaffolding. At the same time, the bolts of the fasteners are prone to rust and thread slippage, and the tightening force is difficult to control, which poses a safety hazard. In addition, the tightness of the bolts needs to be adjusted every time they are installed and removed, and the installation and removal workload is extremely large.

[0029] Based on the above characteristics, the technical solution adopted by the present invention is:

[0030] 1. The two axes of the fastener in the horizontal direction (horizontal and vertical) are integrally formed, and the horizontal and vertical directions are hinged to form a three-axis mutual constraint mechanism, thereby optimizing the fastener structure. Compared with conventional fasteners that can only achieve connection in two directions at the main node, the scaffolding is connected in the horizontal, longitudinal and vertical directions, so that the horizontal steel pipe and the longitudinal steel pipe are set on the same horizontal plane, making the overall force of the scaffolding more reasonable.

[0031] 2. The joints in three directions are hinged to allow the steel pipes in the horizontal direction (including transverse and longitudinal) to rotate appropriately, so as to eliminate or reduce the internal stress between the transverse and longitudinal steel pipes and reduce the deformation of the steel pipes caused by load.

[0032] 3. Set up fastener housing to increase the ability of the main nodes of the scaffolding to withstand external mechanical impact, improve the safety of the scaffolding and the service life of the fasteners.

[0033] 4. The steel pipe and fasteners are fixed with butt pins, which is easier to install and remove than the bolt fastening of conventional fasteners.

[0034] Embodiment 1

[0035] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0036] like Figure 1 , Figure 2 , Figure 3The rotatable scaffolding main node fastener shown has components including a vertical axis, a transverse axis, a longitudinal axis, a shell, and a latch, etc.

[0037] Among them, the vertical axis is provided with a joint and a clamping ring; the transverse axis is provided with a joint and a clamping ring, the longitudinal axis is provided with a joint and a clamping ring, the transverse axis and the longitudinal axis are integrally formed, and a hinge hole is arranged at the intersection of the transverse axis and the longitudinal axis; the joint is used to connect the steel pipe and the fastener, and the clamping ring is used to constrain the relative positions of each axis and the steel pipe.

[0038] After the transverse axis and the longitudinal axis are integrally formed, the vertical axis is connected to the transverse axis and the longitudinal axis through a hinge hole. The three axes form a mutual constraint mechanism through their respective retaining rings, but the transverse axis and the longitudinal axis can rotate appropriately around the vertical axis, and the three axes can always remain perpendicular to each other during rotation.

[0039] In order to protect the core part of the fastener, an outer shell is used to protect the connection parts of the vertical axis, transverse axis and longitudinal axis of the fastener. The outer shell is also divided into three directions: transverse, longitudinal and vertical. Among them, the transverse and longitudinal ends of the outer shell are provided with rotation holes to support the appropriate rotation of the transverse axis and the longitudinal axis. The vertical side of the outer shell is provided with a hinge hole, and the vertical axis passes through the hinge hole, so that the vertical axis, transverse axis, longitudinal axis and outer shell are connected to form a whole.

[0040] Pin holes are arranged on the joints and steel pipes in each direction of the vertical axis, the transverse axis and the longitudinal axis.

[0041] During formal implementation, the vertical steel pipes, transverse steel pipes and longitudinal steel pipes are aligned with the pin holes on the vertical axis, transverse axis and longitudinal axis respectively, and the pins are inserted to complete the connection between the fasteners and the steel pipes. After arranging them in this order, the required scaffolding can be formed.
