Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building engineering, especially a cross bracing structure easy to disassemble. BACKGROUND

[0002] The main function of the cross bracing is to provide lateral support force for the structure to which it is applied, to prevent the structure from deforming or collapsing when subjected to horizontal external force (such as wind force, vibration, etc.), in the field of construction, when the cross bracing is applied to the frame structure or scaffold of a building, it can disperse the horizontal force to the vertical structural members, for example, when erecting a high-level scaffold, the cross bracing connects adjacent vertical rods and horizontal rods to form a stable spatial structure, avoiding the shaking or collapse of the scaffold due to the activities of construction personnel or wind blowing, etc.

[0003] The existing cross bracing is connected by four round pipes, and the round pipe connection mode is plug-in type, which is simple and rough, and has the advantage that the four bracing rods are very firm after being installed in place, but it also leads to very difficult disassembly, which usually requires deformation of the frame and the bracing rod to disassemble. SUMMARY

[0004] The utility model discloses a cross bracing structure easy to disassemble, which solves the deficiencies of the cross bracing structure easy to disassemble in the background art in terms of disassembly and installation.

[0005] The cross bracing structure easy to disassemble provided by the embodiment of the application comprises a cross-shaped connecting piece, a circular slot is symmetrically formed on the cross-shaped connecting piece, a circular support pipe is slidably installed in the circular slot, an elliptical slot is symmetrically formed on the cross-shaped connecting piece, a second elliptical pipe is slidably installed in the elliptical slot, an inner container is fixedly installed in the inner cavity of the second elliptical pipe, a gasket is installed on the inner container through a first fixing piece, a stop pin is fixedly installed on the gasket through a second fixing piece, a U-shaped groove is formed on the stop pin, an axle head is rotatably clamped and connected to the U-shaped groove, a circular limiting block is installed on the other end of the axle head, an axle rod is fixedly installed on the other end of the circular limiting block, and a first elliptical pipe is installed on one end of the axle rod.

[0006] By adopting the technical scheme, the circular support pipe is installed in the upper and lower circular notches of the cross-shaped connector, the second elliptical pipe is installed in the left and right elliptical notches of the cross-shaped connector, the inner container is installed in the inner cavity of the second elliptical pipe, the threaded groove is formed in the side of the inner container exposed from the second elliptical pipe, then the screw is screwed and fixed in the threaded groove through the fixing hole of the gasket, the screw is screwed and fixed in the threaded hole formed in the surface of the gasket through the connecting hole of the stop pin, the shaft rod is installed in the inner cavity of the first elliptical pipe, the circular limiting block is fixedly installed in the side of the shaft rod exposed from the first elliptical pipe, the shaft head is fixedly installed on the circular limiting block, then the first elliptical pipe is held by hand to make the shaft head parallel to the U-shaped groove on the stop pin, the force is applied inwardly, the shaft head is made to enter the U-shaped groove, then the first elliptical pipe is rotated by 90 degrees, the shaft head is made to be clamped with the elliptical groove in the stop pin, then the protrusion on the shaft head is clamped with the protrusion groove on the elliptical groove.

[0007] Optionally, the inner container is provided with a threaded groove, the threaded groove is provided with a gasket through a first fixing member, a fixing hole is formed in the middle of the gasket, and the first fixing member is screwed in the threaded groove through the fixing hole.

[0008] By adopting the technical scheme, the first fixing member is a screw, and the threaded connection can provide greater friction and pre-tightening force. When the screw is screwed into the threaded groove of the inner container through the fixing hole of the gasket, the interaction between the threads can ensure that the gasket will not be easily loosened during use. This is particularly important when the structure is subjected to dynamic loads such as vibration and impact.

[0009] Optionally, a threaded hole is formed in the gasket, a stop pin is fixedly installed in the threaded hole through a second fixing member, a connecting hole is formed in the surface of the stop pin, the position and size of the connecting hole are matched with those of the threaded hole, and the second fixing member is screwed in the threaded hole through the connecting hole.

[0010] By adopting the technical scheme, the second fixing member is also a matching screw. Since the position and size of the connecting hole are matched with those of the threaded hole, the position of the stop pin relative to the gasket can be accurately positioned during installation, preventing the components from falling off.

[0011] Optionally, a circular limiting block is fixedly installed at the end of the shaft rod away from the first elliptical pipe.

[0012] By adopting the technical scheme, during the movement or use of the structure, the circular limiting block can effectively prevent the shaft rod from accidentally falling off from the cooperating component (such as the U-shaped groove of the stop pin).

[0013] Optionally, the shaft rod is an elliptical rod, and the shaft rod is fixedly installed in the inner cavity of the first elliptical pipe.

[0014] By adopting the technical scheme, the shaft rod is an elliptical rod and is fixedly installed in the inner cavity of the first elliptical pipe, and the matched design can effectively prevent the shaft rod from rotating in the pipe cavity.

[0015] Optionally, the shaft head is elliptical, and two protrusions are fixedly installed on the shaft head.

[0016] By adopting the technical scheme, the shaft head is elliptical and has two protrusions, and the shape can provide better rotation stability when cooperating with the U-shaped groove of the stop pin. Compared with a circular shaft head, the elliptical shaft head can reduce unnecessary shaking during rotation. The two protrusions further limit the freedom of the shaft head in the U-shaped groove, so that the shaft head can only rotate within a specific angle range, thereby ensuring the accuracy and stability of the rotation action.

[0017] Optionally, an elliptical groove is formed in the lower end of the U-shaped groove, and a protrusion groove corresponding to the protrusion is formed in the elliptical groove, and the elliptical groove is matched with the shaft head.

[0018] By adopting the technical scheme, when the shaft head rotates in the U-shaped groove, the close matching of the elliptical groove and the shaft head can effectively limit the swinging of the shaft head. Because the shape of the shaft head and the shape of the groove match each other, the shaft head can be kept in the correct position during rotation and cannot swing left and right or up and down.

[0019] Compared with the prior art, the beneficial effects of the technical scheme of the present application are as follows:

[0020] The cross brace improved by the easily detachable cross brace rod of the present application mainly includes elliptical pipes on the left and right sides and circular pipes on the upper and lower sides. The left and right elliptical brace rods can be quickly detached by rotating, and at this time, the remaining brace rod structure can be completely detached from the frame by slightly shaking left and right. The combination of the cross-shaped connecting piece and various rods (circular support pipes, elliptical pipes, etc.) can provide multi-directional support. This structure is more reasonable in space utilization, can effectively disperse loads, and because of the easy-to-detach design, installation and detachment can be quickly completed in different application scenarios, thereby improving work efficiency.
