Description

Technical Field

[0001] The utility model belongs to the technical field of steel frame connection, in particular to a steel frame connection structure. Background Technique

[0002] Currently, the connection between steel feet and steel beams, steel beams and steel beams, etc. generally adopts the welding method. The welding connection method usually has the defect of exposed product solder joints and weld seams. 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 exposed solder joints and weld seams do 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 product competitiveness. In view of the above problems, there is an urgent need for a steel frame connection structure with high connection stability and convenient disassembly. Content of the Utility Model

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

[0005] A column, one end of the column is fixedly connected to the ground;

[0006] An installation groove, fixedly opened at the upper end of the column;

[0007] A cross beam, fixedly inserted in the middle of the installation groove, and the installation groove and the cross beam are fixedly connected by fastening screws;

[0008] The cross sections of the installation groove and the cross beam are square. A second threaded hole is fixedly opened at one end of the cross beam, and the fastening screw is connected in the second threaded hole.

[0009] In this technical solution, when the steel frame is installed, first, one end of the column is fixed to the ground. The lower end of the column can be consolidated by cement or welded, etc. This application does not make specific limitations on this. When the column installation is completed, the cross beam is horizontally inserted into the installation groove, and the cross beam and the column are completely fixed by fastening screws.

[0010] The square cross sections of the installation groove and the cross beam limit the rotational freedom of the two after installation, improving the stability of the connection.

[0011] In any of the above technical solutions, further, the installation groove is cylindrical, a plug is provided at the lower end of the installation groove, and one end of the plug extends from the middle of the installation groove to the outside. A first threaded hole is opened in the middle of the plug.

[0012] A through hole is fixedly provided at the upper end of the installation groove. A pressing block is fixedly provided at the upper end of the through hole, and a third threaded hole is fixedly provided in the middle of the pressing block.

[0013] In this technical solution, in order to ensure the stability of the steel frame after connection, a pressing block is added at the upper end of the through hole. When installing the fastening screw, it passes through the third threaded hole, the second threaded hole and the first threaded hole respectively and finally fixedly connects the three. It should be noted that one end of the plug extends outside the installation groove. When installed with the cross beam, the lower end of the cross beam contacts the extended end of the plug. First, it can increase the stress area between the lower end of the cross beam and the installation groove. Second, it can reduce the shear force received at the contact part between the cross beam and the lower end of the installation groove and extend the service life of the cross beam.

[0014] The beneficial effect of the present utility model is that the cross beam and the column adopt an inserted installation method, and by arranging a plug at the lower end of the installation groove, the installation area between the cross beam and the column is indirectly increased, ensuring the stability of the cross beam after installation. One end of the plug extends to the outside of the installation groove, reducing the shear force at the lower end of the installation part between the cross beam and the column, thus avoiding the wear and damage of the workpiece caused by excessive shear force at the installation end of the cross beam and extending the service life.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0020] Embodiment 1:

[0021] As Figure 1 , 3 shown, this embodiment provides a steel frame connection structure, including:

[0022] The column 10, one end of the column 10 is fixedly connected to the ground;
