Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated steel structures, and specifically relates to a connection node of a prefabricated steel structure. Background Technique

[0002] Prefabricated construction is one of the most important features that the steel structure system is superior to other structure systems. The prefabricated steel structure system refers to a building formed by prefabricating each component of the house in a factory according to certain standards and specifications, and then transporting them to the construction site for on-site assembly. The prefabricated steel structure has the characteristics of fast construction speed, high industrialization degree, labor saving, energy saving and environmental protection;

[0003] The existing prefabricated steel structures are commonly used on shelves for placing goods. The connection nodes of the existing shelves are generally installed by bolts or welding during installation. The bolt connection method requires workers to rotate a number of bolts to complete the installation and disassembly, resulting in a long working time for installation and disassembly, which is not convenient for workers to use. The welding method will cause damage to the shelves during disassembly, which is not convenient for the reuse of the shelves. For this reason, we propose a connection node of a prefabricated steel structure. Content of the Utility Model

[0004] The purpose of the utility model is to provide a connection node of a prefabricated steel structure.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A connection node of a prefabricated steel structure, including a steel structure component, the steel structure component includes a first support frame, a second support frame and an I-shaped frame. The I-shaped frame is located between the first support frame and the second support frame. The bottoms of the first support frame and the second support frame are both fixedly connected with clamping blocks. The tops of the first support frame and the second support frame are both provided with clamping grooves. The clamping blocks can be inserted into the clamping grooves. Clamping plates are arranged at the top and bottom of the I-shaped frame on the inner sides of the first support frame and the second support frame. The clamping plates are installed on the first support frame and the second support frame through a number of bolts. A limiting block is fixedly connected to the top of the I-shaped frame. A slot is opened at the bottom of the clamping plate. The limiting block can be inserted into the slot. A sliding groove is opened on the surface of the limiting block, and a limiting mechanism is arranged in the inner cavity of the sliding groove.

[0006] As a further solution of the utility model: The limiting mechanism includes a spring, a sliding block and a limiting plate. One end of the spring is fixedly connected to the inner wall of the sliding groove. The sliding block is slidably inserted into the sliding groove. The other end of the spring is fixedly connected to the back of the sliding block. The limiting plate is fixedly connected to the surface of the sliding block.

[0007] As a further solution of the utility model: Two limiting blocks are fixedly connected to the I-shaped frame, and two slots are opened at the bottom of the clamping plate, and the two limiting blocks are respectively inserted into the two slots.

[0008] As a further solution of the utility model: Two groups of limiting mechanisms are arranged in each limiting block, and the two groups of limiting mechanisms are respectively located at the front side and the rear side of the inner cavity of the limiting block.

[0009] As a further solution of the utility model: Four first threaded holes are opened on the circumferential surface of the clamping block, and the four first threaded holes are respectively located on the four surfaces of the clamping block. Four bolts are arranged on the first support frame, and the four bolts are respectively arranged corresponding to the positions of the four first threaded holes.

[0010] As a further solution of the utility model: A plurality of second threaded holes are opened on the side surface of the clamping plate, and the plurality of second threaded holes are evenly distributed in an array.

[0011] Adopting the above technical solution, compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] In the utility model, the clamping block at the bottom of one first support frame is inserted into the clamping groove at the top of another first support frame, and then the bolts are inserted into the first threaded holes, so that the two first support frames can be spliced. Similarly, the two second support frames are spliced, and then the first support frame and the second support frame are spliced. First, the two clamping plates are installed on the inner side surface of the first support frame through bolts, and then the limiting plate is pressed inward, so that the limiting plate slides toward the inner side of the sliding groove. The limiting plate will drive the sliding block to slide toward the inner side of the sliding groove. When the sliding block slides, it will squeeze the spring, and then the limiting block is inserted into the slot. Then, the pressing of the limiting plate is released, and the spring will rebound the sliding block. The sliding block will drive the limiting plate to slide toward the outer side of the sliding groove, and the limiting plate will slide to the top of the clamping plate, so that the installation of the I-shaped frame and the first support frame can be realized. Then, the other end of the I-shaped frame is installed with the second support frame, so that the splicing and installation of the first support frame, the second support frame and the I-shaped frame can be realized. Then, another group of steel structure components are spliced with the first group of steel structure components, realizing the convenient installation and disassembly of the shelf, thus achieving the effect of reducing the installation and disassembly time, and not damaging the shelf when disassembling the shelf, which is convenient for the staff to use.

[0013] Other advantages, objectives and features of the utility model will be described to some extent in the subsequent description, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the utility model.
