[0002] As a support system in current construction projects, the safety and stability of scaffolding are particularly important, and the buckle scaffolding has been widely used in many engineering projects due to its quick assembly, convenient use, and cost saving. However, with the increase in the volume of buildings, the construction difficulty increases, which poses a new challenge to the safety and stability of the buckle scaffolding.

[0003] When the construction load on the upper part of the buckle frame is too large, the connection nodes of the buckle frame are easily loosened under the action of vertical construction loads and horizontal unstable wind loads, resulting in reduced stability of the vertical poles near the connection nodes of the buckle frame, causing partial or overall instability and collapse of the buckle frame. Through observation of actual construction on site, it is found that in order to ensure the safety and stability of the connection node structure of the buckle frame, the pin plate of the connection node must be kept vertical to the vertical pole and horizontal to the horizontal bar. However, this requirement cannot be fully met on the current construction site, and problems such as pin plate position offset and angle deviation often occur. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a plug-in anti-collapse disc buckle frame connection node structure, which aims to solve the problem that the disc buckle frame cannot ensure that the pin plate is perpendicular to the vertical pole and horizontal with the cross bar during construction, and further improve the strength of the connection node of the disc buckle frame under the action of vertical construction loads and horizontal unstable wind loads and the performance of resisting upper load impact.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a plug-in anti-collapse disc buckle frame connection node structure, including a disc, a center hole is provided at the center of the disc, and a plurality of holes are evenly provided around the center hole. The casting head is clamped on the hole of the disc through a pin plate, and an anti-loosening mechanism is also provided between the hole, the casting head and the pin plate.

[0006] Furthermore, the anti-loosening mechanism includes a fixing groove arranged on the side of the hole away from the center hole, a casting head pin plate slot arranged on the casting head, and a pin plate arc-shaped protrusion arranged on the pin plate. The fixing groove and the pin plate slot are of the same shape, the cross-sectional shape of the pin plate arc-shaped protrusion is the same as the cross-sectional shape of the fixing groove, and the pin plate is inserted into the fixing groove and the pin plate slot through the pin plate arc-shaped protrusion.

[0007] Furthermore, the pin plate is configured to be wide at the top and narrow at the bottom, and a bending head is provided at the narrowest part.

[0008] Furthermore, the casting head is overall U-shaped, and the opening of the casting head is stuck in the hole on the disc.

[0009] Furthermore, the height of the arc-shaped protrusion of the pin plate is equal to the depth of the casting head pin plate slot on the casting head.

[0010] Furthermore, the holes include small holes and large holes on the disk arranged around the center hole, the small holes on the disk and the large holes on the disk are arranged alternately, the holes include a small hole pin plate slot arranged in the small hole away from the center hole, the fixing groove includes a small hole pin plate slot arranged in the small hole on the disk on the side away from the center hole and a large hole pin plate slot arranged in the large hole on the disk on the side away from the center hole, the small hole on the disk and the large hole on the disk are connected to the casting head and the pin plate through the small hole pin plate slot and the large hole pin plate slot respectively.

[0011] Furthermore, the disc casting head and the pin plate are both made of internal and external hot-dip galvanizing anti-corrosion technology.

[0012] Compared with the existing technology, the utility model has the following beneficial effects: the utility model can ensure the stability of the connection between the hole, the casting head and the pin plate through the anti-loosening mechanism arranged between the hole, the casting head and the pin plate, greatly improving the bearing capacity of the vertical load of the upper supporting template of the disc buckle frame and the horizontal unstable wind load; through the pin plate arc protrusion arranged on the pin plate, the pin plate can be plugged into the small hole pin plate slot in the small hole of the disc and the large hole of the disc, and the large hole pin plate slot can be connected to achieve a tight connection between the pin plate, the disc and the casting head. At the same time, because the pin plate is connected through the pin plate arc The shaped protrusions are plugged into the small-hole pin plate slots, large-hole pin plate slots and casting head pin plate slots on the disc and the casting head, thereby avoiding the problem of pin plate misalignment due to the vertical load on the upper part of the disc buckle frame support system or the unstable horizontal wind load during subsequent construction, and the inability to ensure that the pin plate is parallel to the vertical pole and perpendicular to the horizontal pole, resulting in reduced or even failure of the strength of the disc buckle frame connection node, causing partial or even overall collapse of the disc buckle frame. A large amount of manpower, material and financial resources are saved and the strength of the disc buckle frame connection node is enhanced. The utility model is quick to assemble and easy to use, and can greatly reduce construction costs. BRIEF DESCRIPTION OF THE DRAWINGS

The fixing groove and the pin plate slot 8 have the same shape, and the cross-sectional shape of the pin plate arc-shaped protrusion 7 is the same as the cross-sectional shape of the fixing groove. The pin plate 6 is inserted into the fixing groove and the pin plate slot 8 through the pin plate arc-shaped protrusion 7; the utility model can ensure the stability of the connection between the hole, the casting head 9 and the pin plate 6 through the anti-loosening mechanism provided between the hole, the casting head 9 and the pin plate 6, which greatly improves the vertical load and horizontal instability of the upper support template of the disk buckle frame. The ability to withstand stable wind loads; through the pin plate arc protrusion 7 set on the pin plate 6, the pin plate 6 can be plugged into the small hole pin plate slot 4 and the large hole pin plate slot 5 in the small hole 2 and the large hole 3 of the disk, thereby realizing a tight connection between the pin plate 6, the disk 1, and the casting head 9. At the same time, because the pin plate 6 is plugged into the small hole pin plate slot 4, the large hole pin plate slot 5, and the casting head pin plate slot 8 on the disk 1 and the casting head 9 through the pin plate arc protrusion 7, the pin plate 6 is misaligned due to the vertical load on the upper part of the disc buckle frame support system or the horizontal unstable wind load during subsequent construction, and the pin plate 6 cannot be guaranteed to be parallel to the vertical pole and perpendicular to the cross pole, the strength of the disc buckle frame connection node is reduced or even fails, causing the disc buckle frame to collapse partially or even as a whole, saving a lot of manpower, material and financial resources, and enhancing the strength of the disc buckle frame connection node; the utility model is quick to assemble, easy to use, and can greatly reduce the construction cost.

[0019] Among them, the pin plate 6 is set to be wide at the top and narrow at the bottom, and a bending head 11 is provided at the narrowest part. The bending head 11 can prevent the pin plate 6 from slipping out of the small hole pin plate slot 4, the large hole pin plate slot 5 and the casting head pin plate slot 8 due to vibration, and the setting of wide at the top and narrow at the bottom ensures that the pin plate 6 will not slip out of the small hole pin plate slot 4, the large hole pin plate slot 5 and the casting head pin plate slot 8.

[0020] Among them, the casting head 9 is overall "U-shaped", and the opening of the casting head 9 is stuck in the hole on the disc 1. The "U-shaped" casting head 9 can be firmly stuck in the small hole pin plate slot 4 and the large hole pin plate slot 5 through the pin plate 6.

[0021] The height of the arc-shaped protrusion 7 of the pin plate is equal to the depth of the casting head pin plate slot 8 on the casting head 9.

[0022] Among them, the holes include small disc holes 2 and large disc holes 3 arranged around the center hole 10, and the small disc holes 2 and the large disc holes 3 are arranged alternately. The holes include a small hole pin plate slot 4 arranged away from the center hole 10, and the fixing groove includes a small hole pin plate slot 4 arranged on the side of the small disc hole 2 away from the center hole 10 and a large hole pin plate slot 5 arranged on the side of the large disc hole 3 away from the center hole 10. The small disc hole 2 and the large disc hole 3 are connected to the casting head 9 and the pin plate 6 through the small hole pin plate slot 4 and the large hole pin plate slot 5 respectively.

[0023] In summary, the working process of the utility model is as follows: during installation, taking the small hole 2 of the disk as an example, the disk 1 is installed on the vertical rod of the disk buckle frame through the center hole 10, and then the casting head 9 is clamped at the position of the small hole 2 of the disk 1 (the casting head 9 is used to connect the cross bar or the inclined rod), so that the casting head pin plate slot 8 on the casting head 9 and the small hole pin plate slot 4 in the small hole 2 of the disk are on the same axis, and the pin plate 6 is inserted after alignment, so that the arc-shaped protrusion 7 of the pin plate on the pin plate 6 passes through the casting head pin plate slot 8 and the small hole pin plate slot 4. Due to the design of the pin plate 6 being wide at the top and narrow at the bottom, after the arc-shaped protrusion 7 of the pin plate passes through the casting head pin plate slot 8 and the small hole pin plate slot 4 to connect the casting head pin plate slot 8 and the small hole pin plate slot 4 together, the pin plate 6 no longer falls, that is, the installation is completed; the method of installing the casting head 9 on the large hole 3 of the disk is the same as that of the small hole 2 of the disk.
