Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to an assembled steel structure crossbeam. Background Art

[0002] Prefabricated structure is the abbreviation of prefabricated concrete structure, which is a concrete structure formed by assembling and connecting prefabricated components as the main load-bearing components. The prefabricated beams need to have sufficient strength and rigidity to bear the load above and transfer the load to the pillars.

[0003] At present, when installing beams in most structures, external angle steels and embedded plates are directly used and fixed with fastening bolts. However, the position of the beams is difficult to control during fixation, resulting in the displacement of the beams and the positions of the pillars. As a result, the beams and pillars cannot achieve the best support effect for the buildings above.

[0004] When using most steel structure beams, the user pours water between the column and the ground, and then connects the crossbar to the joint of the column surface. However, when the equipment is in use, the crossbar is generally welded to the surface of the column to be firmly welded. Most of the existing crossbars are hoisted at high places to achieve docking. Due to the heavy weight of the crossbar, it is difficult to accurately position it during installation, resulting in installation position deviation. In addition, the crossbars are mostly directly fixed and connected by bolts during installation, and tools are required to fix the bolts, which makes the process steps cumbersome.

[0028] When the crossbar is welded, a support is required to position and support the crossbar. By setting an adjustment device, the height of the crossbar can be effectively adjusted to prevent the crossbar from shaking, which may cause deviations in the crossbar welding and make it impossible to accurately position the crossbar. By setting a connection device, the crossbars can be effectively connected, avoiding the cumbersome process caused by the traditional use of bolts for fixing and connection, and improving the work efficiency of users.

[0029] Embodiment 2

[0030] See also Figure 2-Figure 4 The adjusting device 4 includes a first adjusting block 41 and a second adjusting block 42. The first adjusting block 41 is connected to the inner wall of one side of the column 1, and the second adjusting block 42 is connected to the inner wall of the opposite side of the column 1. The surface of the first adjusting block 41 is fixedly connected with a supporting block 43, and the upper surface of the supporting block 43 is connected to the lower surface of the first cross bar 2. The side of the second adjusting block 42 is fixedly connected with a rack 44, and the rack 44 is slidably connected to the inner wall of the first adjusting block 41. The inner wall of the first adjusting block 41 is rotatably connected with a gear 45, and the gear 45 is meshed with the surface of the rack 44.

[0031] A rotating wheel 46 is fixedly connected to the surface of the gear 45, and a limiting hole 47 is opened on the surface of the rotating wheel 46. A connecting column 48 is fixedly connected to the surface of the first adjustment block 41, and a limiting rod 49 is slidably connected to the inner wall of the connecting column 48. One end of the limiting rod 49 is clamped with the inner wall of the limiting hole 47.

[0033] The user waters the column 1 and the ground, and then connects the cross bar to the surface of the column 1. When the equipment needs to be used, the user pulls the limiting rod 49 to move and drive the first spring 410 to displace and deform to generate elastic force. Then the limiting rod 49 is separated from the inside of the limiting hole 47, and then the rotating wheel 46 loses its restraint and rotates. The rotating wheel 46 drives the gear 45 to rotate, and the rotation of the gear 45 drives the rack 44 to move. The movement of the rack 44 can make the second adjustment block 42 and the first adjustment block 41 move up and down relative to the column 1. By setting the adjustment device 4, the height of the cross bar can be effectively adjusted.

The stabilizing rod 56 moves out of the interior of the connecting hole 54, and the connecting rod 53 is freed from restraint. The first connecting plate 51 is pulled to move and drive the connecting rod 53 to disengage from the interior of the second cross bar 3, and the first cross bar 2 and the second cross bar 3 are freed from restraint.
