Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a rapid connection structure for steel structure joints. Background Technique

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and adopts rust removal and anti-rust processes such as silanization, pure manganese phosphating, water washing and drying, galvanizing, etc. The components or parts are usually connected by welds, bolts or rivets. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings, bridges and other fields.

[0003] When the existing rapid connection structure for steel structure joints connects two steel beams or steel columns, since the angle between the rapid connection structures is usually 90 degrees or 180 degrees, in the construction of special-shaped walls, the steel beams or steel columns need to be adapted at multiple angles, but the conventional steel structure connection structure cannot meet this requirement, and there are certain limitations. Content of the Utility Model

[0004] The purpose of the utility model is to provide a rapid connection structure for steel structure joints in order to solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A rapid connection structure for steel structure joints includes a first connection block. One side of the first connection block is rotatably connected to a second connection block. Bolts for fixing the steel structure are provided on one side of the first connection block and the second connection block. A disc is fixedly connected to the top of the first connection block. A circular groove is opened on the top of the disc. A positioning member for preventing the first connection block from rotating is installed on the second connection block.

[0007] Preferably, the positioning member includes a block for inserting into the circular groove. A support rod for enabling the block to move only up and down is slidably connected to the inner wall of the block. An annular groove for allowing the support rod to move in the disc is communicated with one side of the circular groove. A support frame for fixing the support rod is fixedly connected to the outer wall of the second connection block. A clamping plate for limiting the block is slidably connected to the top of the second connection block. A limiting groove for allowing the support rod to slide is opened on the clamping plate. A limiting rod for enabling the clamping plate to move only horizontally is slidably connected to the inner wall of the clamping plate.

[0008] Preferably, a spring for pushing the clamping plate to move is sleeved on the outer wall of the limiting rod. One end of the limiting rod is fixedly connected to a support block for supporting the spring.

[0009] Preferably, one side of the clamping block is fixedly connected with a push plate for facilitating the staff to move the clamping block.

[0010] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0011] In this application, when connecting steel structures and encountering special-shaped walls, the staff first move the clamping plate away from the clamping block, and then grasp the push plate to move the clamping block upward, so that the clamping block will disengage from the circular groove, and thus the disc will lose its limit. The staff can then adjust the angle between the first connecting block and the second connecting block. After the angle adjustment is completed, the staff insert the clamping block into the circular groove, and then release the clamping plate. The spring will then push the clamping plate to limit the clamping block, thus facilitating the staff to adjust the connection angle between the steel structures. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0019] Embodiment 1:

[0020] As Figures 1-3As shown in the figure, a rapid connection structure for steel structure joints includes a first connecting block 1. One side of the first connecting block 1 is rotatably connected to a second connecting block 2. Bolts 3 for fixing the steel structure are provided on one side of both the first connecting block 1 and the second connecting block 2. The top of the first connecting block 1 is fixedly connected to a disc 4. A circular groove 5 is formed on the top of the disc 4. The number of circular grooves 5 is set to be multiple, and the multiple circular grooves 5 are arranged at equal intervals in a ring shape with the disc 4 as the center. A positioning member for preventing the first connecting block 1 from rotating is installed on the second connecting block 2.

[0021] Embodiment 2:

[0022] It is basically the same as the technical solution of Embodiment 1, except that, as Figure 2 shown, the positioning member includes a clamping block 6 for inserting into the circular groove 5. The clamping block 6 is composed of three circular blocks connected to each other. A support rod 7 for enabling the clamping block 6 to move only up and down is slidably connected to the inner wall of the clamping block 6. An annular groove 8 for allowing the support rod 7 to move within the disc 4 is communicated with one side of the circular groove 5. The center of the annular groove 8 is the same as the center of the disc 4. A support frame 9 for fixing the support rod 7 is fixedly connected to the outer wall of the second connecting block 2. A clamping plate 10 for limiting the clamping block 6 is slidably connected to the top of the second connecting block 2. A limiting groove 11 for allowing the support rod 7 to slide is formed on the clamping plate 10. A limiting rod 12 for enabling the clamping plate 10 to move only horizontally is slidably connected to the inner wall of the clamping plate 10. A spring 13 for pushing the clamping plate 10 to move is sleeved on the outer wall of the limiting rod 12. The spring 13 is fixedly connected to one side of the clamping plate 10. One end of the limiting rod 12 is fixedly connected to a support block 14 for supporting the spring 13.

[0023] Embodiment 3:

[0024] It is basically the same as the technical solution of Embodiment 1, except that, as Figure 2 shown, a push plate 15 for facilitating the movement of the clamping block 6 by the staff is fixedly connected to one side of the clamping block 6. The shape of the push plate 15 is set to be L-shaped.

[0025] In summary, when the rapid connection structure for steel structure joints provided in this embodiment faces a special-shaped wall, the staff first move the clamping plate 10 so that the clamping block 6 can move up and down. Then the staff grasp the push plate 15 to move the clamping block 6 upward, and the clamping block 6 will move out of the circular groove 5. In this way, the disc 4 will lose its limit, and the staff can rotate between the first connecting block 1 and the second connecting block 2. At the same time, the support rod 7 will slide in the annular groove 8, so that the angle between the connection structures can be adjusted. After the angle adjustment is completed, the staff can move the clamping block 6 to insert it into the inside of the circular groove 5. Then the staff can release the clamping plate 10, and the spring 13 will push the clamping plate 10 to limit the clamping block 6. In this way, the clamping block 6 cannot move out of the circular groove 5, and the first connecting block 1 and the second connecting block 2 will be fixed at the specified angle and will not rotate.
