[0001] The utility model relates to the technical field of building engineering, in particular to a steel structure bracket for building which is easy to assemble and disassemble. Background Art

[0002] With the development of society, the application of steel structure has become more and more extensive. Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts silanization, pure manganese phosphating, water washing and drying, galvanizing and other rust removal and rust prevention processes. The components or parts are usually connected by welds, bolts or rivets.

[0003] The existing building supports generally use two steel pipes to socket and then use bolts to fix and splice them. This connection method is not only cumbersome to install, but also requires a lot of time to check whether the bolts are tightened to ensure safety. At the same time, when disassembling, the bolts will be eroded by rainwater, resulting in thread stripping and difficulty in disassembly. Therefore, the applicant has made a useful design and found a solution to the above problems. The technical solution to be introduced below was produced in this context. Summary of the invention

[0009] Preferably, the pillars of the base are provided with reinforcing ribs, the base is provided with a plurality of positioning holes, the base is located at the bottommost position of the connecting piece, and the top plate is located at the topmost position of the connecting piece.

[0010] Preferably, the cross bar is provided with a protrusion, the cross bar is provided with a clearance groove, the clearance groove is provided with a top block, the two ends of the clearance groove are provided with a first concave cavity, the central bottom of the clearance groove is provided with a blind hole, the opposite side of the blind hole is provided with an avoidance through hole, the protrusion is provided with a second concave cavity and is connected with the avoidance through hole, the side wall of the protrusion is provided with a movable through hole and passes through the second concave cavity, and the top of the second concave cavity is provided with an end cover.

[0011] Preferably, the movable column is arranged in the first concave cavity, the rack is arranged in the yielding groove and abuts against the top block, and the rack is arranged in opposite surfaces.

[0012] Preferably, the worm is arranged in the movable through hole, nuts are provided on both sides of the worm and abut against the two ends of the movable through hole, and the nuts are provided with hexagonal grooves.

[0013] Preferably, the transmission assembly includes a first gear and a second gear, a connecting shaft is provided between the first gear and the second gear, and is arranged in the avoidance through hole, the first gear is provided with a fixed shaft, and abuts against the end face of the blind hole, the first gear meshes with the rack, and the second gear is arranged in the second concave cavity and meshes with the worm.

[0014] Preferably, the shape of the elastic sheet is set to be an arc.

[0015] Beneficial effects:

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] (1) The utility model drives the first gear to rotate by rotating the worm, and the second gear rotates coaxially with the first gear, thereby causing the movable column to extend out of the first cavity and move until the movable column abuts against the end face of the interface. At this time, the rotating worm has great resistance, which means that the connection between the cross bar and the interface is completed. Similarly, the connection between the cross bar and the connecting piece is disassembled by rotating the worm, so that the movable column leaves the interface to complete the disassembly. Since the transmission assembly and the worm are arranged inside the cross bar, they will not be corroded by rainwater, and obstacles will be prevented during disassembly and assembly, so that the product has the advantages of easy disassembly and assembly and improved disassembly and assembly efficiency.

[0018] (2) In the present invention, since the gear teeth of the second gear are of straight line profile and the gear teeth of the worm are of helical line profile, the two have different profile shapes. Therefore, the rotation of the second gear does not cause the worm to rotate, thereby ensuring that the movable column is tightly abutted against the end face of the interface to ensure a stable connection. The spring clip clamps the support column and the movable column through its own elastic force to prevent the support column and the movable column from vibrating and affecting the stability of the connection, thereby giving the product the advantage of reliable connection.

The second gear 62 is arranged in the second concave cavity 231 and meshes with the worm 7. The first gear 61 drives the gear to rotate, and the first gear 61 and the second gear 62 rotate coaxially through the connecting shaft 63. The fixed shaft 64 cooperates with the blind hole 27 to make the first gear 61 and the second gear 62 rotate with the blind hole 27 as the axis.

[0047] It is worth mentioning that the shape of the spring piece 33 is set to be arc-shaped.

[0048] The use principle of the utility model is now described as follows:

[0049] Place the bottom plate on the ground, take the connecting piece 3, align the interface 31 with the support 5 of the base 1, apply downward pressure to the connecting piece 3, the support 5 of the base 1 pushes the spring sheet 33, so that the arc of the spring sheet 33 is compressed and stores energy, until the support 5 of the base 1 abuts against the base plate 321, and the spring sheet 33 clamps the support 5 of the base 1 with the reaction force. Similarly, the installation steps of the top plate 4 are the same as those of the bottom plate;

[0050] Take the crossbar 2, and place the end of the crossbar 2 against the end of the interface 31. Use a tool to rotate the worm 7, which in turn drives the second gear 62. The rotation force of the second gear 62 causes the first gear 61 to coaxially rotate through the connecting shaft 63, so that the two racks 22 move in opposite directions. The movable column 21 enters between the spring pieces 33 until the movable column 21 abuts against the base plate 321. The spring pieces 33 release the reaction force to clamp the movable column 21. At this time, the rotating worm 7 has a large resistance, which means that the installation is completed.

[0051] When disassembling the cross bar 2, it is only necessary to rotate the worm 7 in the opposite direction, so that the first gear 61 and the second gear 62 rotate in the opposite direction, and the rack 22 moves in the direction of the top block 25. Since the output torque of the worm 7 is larger, the movable column 21 can be easily pulled out from the interface 31 until the rack 22 abuts against the top block 25 and the rotating worm 7 has a large resistance, which means that the disassembly is completed.

[0052] The above design scheme can make the product easy to disassemble and assemble, improve the disassembly and assembly efficiency, and have the advantages of reliable connection.
