[0002] In the prior art, the connection between steel feet and steel beams, frames and steel beams, etc. generally adopts a welding method. The welding connection method usually has the defect that the solder joints and weld seams of the products are exposed. Moreover, the welded steel frame structure has disadvantages such as being non-detachable, non-recyclable, poor versatility of steel beam components, and high economic costs. The exposure of solder joints and weld seams does not meet the current customer requirements.

[0003] Therefore, how to achieve a split-type steel frame connection method with low manufacturing cost, simple structure, good appearance and use effect is the key to improving the competitiveness of products. In view of the above problems, there is an urgent need for a steel frame connection structure with high connection stability and convenient disassembly. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a steel frame connection structure to solve the problems of poor versatility of steel beam components, high economic cost, and inability to install quickly proposed in the above background art. The following technical solutions are provided: A steel frame connection structure, including:

[0005] A cross beam and a frame, the cross beam and the frame are in mutual abutment;

[0006] Hanging grooves are opened at the lower ends of the cross beam and the frame;

[0007] A hoop is clamped at the lower ends of the cross beam and the frame;

[0008] A hook is fixedly arranged at the bottom of the hoop, and the hook is clamped with the hanging groove;

[0009] The cross beam, the frame and the hoop are tightly connected by fastening screws; a first through hole is horizontally opened in the middle of the cross beam, a second through hole is horizontally opened in the middle of the frame, and the first through hole and the second through hole respectively penetrate through the cross beam and the frame.

[0010] In this technical solution, when connecting the steel frame, first, the end faces of the cross beam and the frame are attached together. After the frame clamping block cooperates with the cross beam positioning groove, the first through hole and the second through hole are aligned. At this time, the hoop is buckled from the bottom of the cross beam and the frame, and the fastening screws are sequentially passed through the first through hole, the hoop and the second through hole and fixed, so as to realize the rapid installation of the whole structure.

[0011] In any of the above technical solutions, further, an installation hole is horizontally opened in the middle of the hoop, and the installation hole is horizontally communicated with the first through hole and the second through hole.

[0012] The fastening screws respectively pass through the first through-hole, the second through-hole and the mounting hole, and fix the cross beam, the frame and the hoop. The cross-section of the hoop is U-shaped, and the depth is the same as the heights of the cross beam and the frame. The cross-sections of the cross beam and the frame are respectively in a hollow grid shape, and the sizes of the cross-sections of the cross beam and the frame are the same.

[0013] In this technical solution, in order to improve the stability of the hoop after being installed and fixed to the cross beam and the frame, when the hoop is butted with the cross beam and the frame, the hook just snaps into the hanging groove, thereby restricting the freedom of mutual movement between the three in the horizontal plane. The cross-section of the hoop is U-shaped, the depth of the bottom of the U-shape is equal to the heights of the cross beam and the frame, and the width of the combined cross beam and the frame is also exactly equal to the width of the U-shaped part of the hoop, so that the hoop can be perfectly snapped into the cross beam and the frame.

[0014] In any of the above technical solutions, further, the number of the hanging grooves is the same as the number of the hooks. One end of the cross beam is also provided with a positioning groove, and one end of the frame is provided with a clamping block, and the clamping block is clamped in the positioning groove.

[0015] In this technical solution, when the cross beam and the frame are butted, in order to ensure that the first through-hole and the second through-hole can be quickly aligned, through the provided positioning groove and the clamping block, the two are clamped with each other to initially fix the positions of the cross beam and the frame. And after the positioning groove and the clamping block are clamped, the freedom of the two along their extending directions is restricted, increasing the rigidity and stability of the whole structure.

[0016] The beneficial effects of the present utility model are as follows: In this application, through the provided hoop, during installation, the hoop is positioned with the cross beam and the frame by the clamping of the hanging groove provided at its lower end and the hook, and finally the fastening connection is realized through the fastening screw. Also, by providing the positioning groove and the clamping block, the clamping between the two increases the rigidity of the structure. Thus, on the basis of a simple structure, the overall stability of the steel frame is improved, and the whole structure is convenient for disassembly and assembly, and has a low manufacturing cost.
