In order to share the load, multiple steel structures are usually required to be spliced ​​together. By setting the steel structure to an "H" shape, the cross-sectional shape can be effectively used to optimize its area distribution, thereby improving its strength-to-weight ratio. When splicing steel structures, a connecting structure is required to connect and fix the two steel structures.

By opening a connection hole for use with the component on the H-shaped steel body and providing a reverse clamp on the connection, the installation of the parts can be made more convenient, the investment of labor and time can be reduced, and the efficiency of the project can be increased; by providing a magnet on the component for use with the connection hole, and the structural design of the support plate being set as a rough surface, the connection component is not easy to fall off when in use, which increases the stability of the component when in use.

[0004] However, the following problems still exist in the current use of steel structure connection components:

[0005] The above-mentioned steel structure connection structure adopts a snap-fitting method to limit the butt connection of the two steel structures during use. Therefore, when the steel structure is subjected to a large force during use, the component body is very likely to deform or break. At this time, it is difficult to achieve the purpose of butt connection of the two steel structures. In addition, the stability of the connection through snap-fitting is poor, and it is difficult to ensure the stability of the two steel structures after butt connection. Moreover, when there is a certain gap between the two steel structures, it will be difficult to limit the butt connection. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figure 1-Figure 6 The utility model provides a technical solution: a connection structure for assembling a heavy steel structure, comprising a connection plate 1, a fixing plate 2 which is symmetrically arranged on the left and right sides and fits the steel structure, and a fastening screw 3 is arranged through the fixing plate 2, and the fastening screw 3 is arranged through the steel structure; the fastening screw 3 has a fastening nut 4 threadedly connected at its lower end;

[0024] When two steel structures need to be assembled and fixed, the connecting plate 1 is placed on the side of the steel structure that needs to be assembled. Since the fixing plate 2 is installed on the connecting plate 1, the fixing plate 2 can be used to support the steel structure. Then, the fastening screw 3 is passed through the fixing plate 2 and the steel structure. Then, the fastening nut 4 is rotated to connect the fastening nut 4 with the threaded structure set at the lower end of the fastening screw 3. At this time, the fastening nut 4 can be fixed to the lower end of the fastening screw 3, so that the connection and fixation between the connecting plate 1 and the steel structure can be achieved.

[0025] A connecting assembly 5 is arranged in the square groove opened on the connecting plate 1; the connecting assembly 5 includes an extension plate 501 and a connecting screw 502, and the extension plate 501 is slidably connected with the connecting plate 1 through the square through groove opened on the connecting plate 1, and the connecting screw 502 is penetrated and arranged on the steel structure, and the connecting screw 502 is connected to the extension plate 501 through the first threaded hole opened on the extension plate 501; the extension plate 501 is arranged as a square plate-shaped structure, and the side of the extension plate 501 is provided with second threaded holes at equal distances, and the extension plate 501 is provided with two symmetrical holes up and down about the transverse axis of the connecting plate 1;

[0026] As the connecting plates 1 are installed on both steel structures, the extension plate 501 is passed through the square through groove opened on the connecting plate 1, and the connecting screws 502 are passed through the through holes opened on the side of the steel structure, and then rotated. The connecting screws 502 begin to connect with the threaded holes opened on the side of the extension plate 501, so that the extension plate 501 and the connecting plate 1 can be installed and fixed. Because a plurality of threaded holes are opened on the side of the extension plate 501, steel structures with different gaps can be connected and fixed under the action of the extension plate 501 (during the splicing process of the steel structure, there may be a certain amount of error in the spacing between them, and it is not possible to assemble them completely without gaps), so as to achieve the assembly, connection and fixation of the steel structure.

[0027] A limit assembly 6 is provided on the connecting plate 1, and the limit assembly 6 fits with the steel structure; the limit assembly 6 includes a fixed shaft 601 and a sliding plate 602, and the fixed shaft 601 is fixedly mounted on the connecting plate 1, and the sliding plate 602 is symmetrically distributed about the center of the connecting plate 1; the limit assembly 6 also includes a rotating plate 603 and a vortex spring 604, and the sliding plate 602 is slidably connected with the rotating plate 603 through an annular groove provided at the lower end of the rotating plate 603, and the vortex spring 604 is fixedly mounted in a through cylindrical groove provided on the rotating plate 603, and the vortex spring 604 is fixedly mounted on the fixed shaft 601; the limit assembly 6 also includes a positioning rod 605 and a positioning spring 606, and the positioning rod 605 is penetrated and arranged on the rotating plate 603, and the positioning rod 605 is engaged with the steel structure through a cylindrical positioning groove starting from the upper surface of the steel structure, the positioning spring 606 is connected to the positioning rod 605, and the positioning spring 606 is fixedly mounted on the upper end of the rotating plate 603;

[0028] After the two steel structures are assembled, the positioning rod 605 is pulled, and the positioning rod 605 begins to move away from the rotating plate 603. Because the positioning spring 606 is installed on the positioning rod 605, the positioning spring 606 begins to be stretched and deformed. Then the rotating plate 603 is rotated. Because the rotating plate 603 fits with the sliding plate 602 through the annular groove, the sliding plate 602 can support the rotating plate 603 without affecting the rotation of the rotating plate 603. At this time, the rotating plate 603 begins to rotate around the fixed shaft 601, and the fixed shaft 601 is installed outside The vortex spring 604 begins to be compressed and deformed. When the rotating plate 603 is rotated to the upper end of the steel structure, the positioning rod 605 is loosened. Under the action of the positioning spring 606 restoring the deformation, the positioning spring 606 begins to drive the positioning rod 605 to move in the direction close to the rotating plate 603 until the positioning rod 605 and the cylindrical positioning groove opened on the steel structure fit each other. At this time, auxiliary limiting can be achieved between the connecting plate 1 and the steel structure, so that when the fastening screw 3 and the fastening nut 4 fall off, a certain degree of connection limiting can be performed to avoid direct loosening between the two steel structures.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
