[0002] Scaffolds are widely used in departments such as the advertising industry, municipal administration, traffic road bridges, and mines. A scaffold is a working platform built for facilitating high-altitude building construction operations. Most of the existing scaffolds are composed of multiple crossbars and multiple vertical bars assembled and fitted together. During the assembly process, a large number of bolts are used to connect adjacent rod bodies, or the joints of the rod bodies are connected by welding (forming joints). Both of the above connection methods have the defects of having a large number of independent components, heavy assembly workload, extended project cycle, and inability to flexibly adjust the height of the working platform according to construction requirements. The first connection method also has the problem that a large number of bolts are loosened due to factors such as fatigue during long-term use, and it is not easy to disassemble; the second connection method also has the problem that it cannot be disassembled, resulting in inconvenience for transfer and storage. At the same time, the problems of resource waste and noise pollution of the scaffold cannot be ignored, which is not conducive to green construction and environmental protection.

[0003] Therefore, it is urgent to take effective measures to improve the installation and disassembly processes of the scaffold to enhance the overall level of building construction. Summary of the Utility Model

[0029] The present utility model will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0030] Referring to the appendix Figure 1 - 11 as described, the present utility model relates to a construction scaffolding, the main structure of which includes a vertical pole 1, a cross bar 2 and a diagonal brace 3. A plurality of clamping positions 11 are provided on the vertical pole 1. The two clamping ends of the cross bar 2 are provided with a first mechanical locking device 4 in cooperation with the clamping positions 11. The first mechanical locking device 4 on the cross bar 2 is mechanically locked on the clamping position 11 of the vertical pole 1 to form a stable connection node, such as Figure 2 - 5 as described, when in use, it only needs to use a hammer to strike the first mechanical locking device 4 to fix it, such as Figure 4 as described, striking in the reverse direction can release the fixation, reducing the installation and disassembly time, and at the same time greatly reducing the risk of loosening;

[0031] For the specific structure, it is symmetrically arranged on both sides of the cross bar 2. Because of the symmetrical arrangement, only one end will be introduced below. A rectangular card slot 21 is provided at one end of the cross bar 2. A mechanical housing 22 is provided outside the rectangular card slot 21. The mechanical housing 22 is a U-shaped housing. The rectangular card slot 21 is enclosed by the U-shaped mechanical housing 22 to form an enclosed space 23, such as Figure 11 as described, the mechanical housing 22 penetrates the cross bar 2, such as Figure 2 as described;

[0032] See attached Figure 4 As described above, a first clamping block 231 and a second clamping block 232 are respectively provided in the enclosed space 23 from the outside to the inside. Figure 4 The first clamping block 231 is movably arranged in the mechanical housing 22, and one end of the second clamping block (232) is movably arranged in the rectangular clamping slot 21. The contacting ends of the first clamping block 231 and the second clamping block 232 are inclined and convex and concave to fit each other, and the inclined surfaces between the two are in contact. Figure 5 As described above, a downward force F is applied to the first clamping block 231, which will push the second clamping block 232 along the rectangular clamping slot 21 to Figure 5 The first clamping block 231 on the outside is a convex side, and the second clamping block 232 on the inside is a concave side. The bottom of the second clamping block 232 is matched with the clamping position 11 and a buckle 233 is provided. The buckle 233 of the second clamping block 232 extends from the bottom of the mechanical housing 22 to limit the movement of the second clamping block 232. Figure 2 , 3 As described above, the mechanical housing 22 of the first mechanical locking device 4 is clamped on the clamping position 11 of the vertical pole (1), and a hammer is used to apply force F to hammer the first clamping block 231 downward. The first clamping block 231 moves downward and the second clamping block 232 moves upward. Figure 5 The second clamping block 232 moves in the direction of the middle arrow. At the same time, because the bottom of the second clamping block 232 is equipped with a clamping buckle 233 to match the clamping position 11, the clamping buckle 233 hooks the clamping position 11 of the vertical rod (1). As a result of the movement of the second clamping block 232, the node between the cross bar 2 and the vertical rod 1 can be mechanically clamped. Figure 5 , 6 A silicone buffer block 234 is further provided in the enclosed space 23. The silicone buffer block 234 is fixed inside the second clamping block 232 for buffering. When the second clamping block 232 moves inward, the silicone buffer block 234 inside can achieve a certain noise reduction effect.

[0033] A counterweight block 2311 is provided at the bottom of the first clamping block 231 to facilitate knocking and prevent loosening. Each clamping position 11 on the vertical rod (1) is arranged in a 90-degree circular array, that is, there are a total of 4 clamping positions 11. Figure 2 described.

[0034] The above-mentioned scaffolding with only the crossbar 2 has the advantages of simple structure, easy to build and dismantle, less material is used, low cost, suitable for simple construction scenes, and does not require excessive reinforcement.

[0035] It is suitable for low-rise buildings or short-term construction projects, as well as occasions that do not bear large loads, such as exterior wall decoration, temporary supports, etc., as well as construction areas with smaller spaces, and has strong flexibility.

[0036] The following describes the occasions where high-rise building construction is applicable, where large loads need to be borne, for construction projects that need to be used for a long time, the construction process is relatively complex and heavy, and in special environments, such as areas with strong winds. At this time, using the cross bracing 3 can greatly increase the stability and load-bearing capacity of the scaffolding. Because the cross bracing 3 provides additional support and tensile force dispersion, making the overall structure more solid. Making itself more wind-resistant and earthquake-resistant, suitable for complex construction environments.

[0037] Refer to the appendix Figure 8 - 10 As described, the cross bracing 3 is clamped on the clamping position 11 and forms a stable structure together with the vertical pole 1 and the horizontal pole 2, such as Figure 8 As described, suitable for complex construction environments.

[0038] The cross bracing 3 includes two cross bracing connecting rods 31 and a horizontal fixing rod 32. At the top of the cross bracing connecting rod 31, a hook 311 is provided in cooperation with the clamping position 11. A fixing hole 312 is provided on the hook 311. The horizontal fixing rod 32 is hinged between the two cross bracing connecting rods 31 through the fixing hole 312 to limit the movement of the cross bracing connecting rod 31; on the other side of the cross bracing connecting rod 31, a second mechanical locking device 5 is provided. The second mechanical locking device 5 includes a horizontal clamping block 51 and a clamping pin 52. A clamping opening 511 is provided in the center of the horizontal clamping block 51 in cooperation with the clamping position 11, and the clamping opening 511 is clamped on the clamping position 11 of the vertical pole 1. The clamping pin 52 includes a pin handle 521 and a pin head 522. A pin handle 521 hole and a pin head 522 hole are provided on the horizontal clamping block 51 in cooperation with the pin handle 521 and the pin head 522. The clamping pin 52 is connected in the corresponding holes of the horizontal clamping block 51. The pin head 522 is inclined on the side away from the vertical pole 1. When the clamping opening 511 is clamped on the clamping position 11 of the vertical pole 1, by knocking the clamping pin 52, the pin head 522 passes through the clamping position 11 of the vertical pole 1, and mechanical locking can be achieved. Increasing the pin handle 521 can further enhance the effect of mechanical locking, and can also prevent the pin head 522 from falling off, greatly reducing the risk of loosening and also reducing the installation time.

[0039] A transition groove 313 is provided at the central position of the cross bracing connecting rod 31, such as Figure 8 、 9 As described, because of the existence of the transition groove 313, the two cross bracing connecting rods 31 can be used in cooperation with the horizontal pole 2 and the vertical pole 1 without the need to additionally adjust the horizontal pole 2 and the vertical pole 1.

[0040] Such as Figure 7As described above, this is the structure required for connecting between two vertical rods 1. It further includes a connecting pin 6. The top of the vertical rod 1 is provided with a connecting end 12, and the connecting end 12 is directly sleeved in cooperation with the diameter of the vertical rod 1. The connecting end 12 is provided with a first connecting hole 13, and the bottom of the vertical rod 1 is provided with a second connecting hole 14. The connecting pin 6 passes through the first connecting hole 13 and the second connecting hole 14 to fix the upper and lower vertical rods 1.
