Problems solved by technology

[0003] In the prior art, generally only bolts are used to tighten and fix the joints of prefabricated building structures. In this way, when the joints are stressed, the bolts are likely to be deformed or the force is unstable, resulting in the joints being connected. Insufficient strength, which will affect the overall stability of the prefabricated building structure, and when using bolts to fix, in order to strengthen the strength, it is necessary to use multiple sets of bolts for reinforcement, so that the entire prefabricated building structure needs to be spent on assembly. A large amount of time makes the overall assembly time longer and the construction period longer. Therefore, the node connection structure of the existing prefabricated building structure cannot meet the needs of use. Aiming at the deficiencies of the prior art, the present invention discloses a prefabricated building structure. Node connection means to solve the above problems

Abstract

The invention discloses a node connection device used for a prefabricated building structure, and relates to the field of prefabricated buildings. The node connection device for prefabricated building structure comprises a column, the side wall of the column is fixedly connected with a square tube seat, the tube cavity of the square tube seat is movably inserted with a cross bar, and the top of the cross bar is provided with two sets of fixing holes. A fixing bolt is movably inserted in the fixing hole. The fixing bolt extends upward through the square tube seat and the fixing hole and is threadedly connected with a fixing nut. A reinforcing rib is fixedly installed between the column and the cross bar, and a top block is fixed on the top of the reinforcing rib. A first insertion post is fixed on the top of the top block, and two sets of locking holes are opened on the side wall of the first insertion post. When the node connecting device for prefabricated building structure is in use, it is convenient to assemble and connect the nodes of the prefabricated building structure. When assembling, it saves time and effort and realizes quick assembly.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a node connection device for prefabricated building structures. Background technique [0002] Prefabricated buildings refer to buildings that are assembled on site with prefabricated components. The advantages of this kind of building are fast construction speed, convenient construction, less restricted by climatic conditions, labor saving and improved construction quality. In recent years, the construction method of prefabricated buildings has attracted more and more attention and application. [0003] In the prior art, when connecting the nodes of prefabricated building structures, only bolts are usually used for tightening and fixing, so that when the nodes are stressed, the bolts are likely to be deformed or unstable, resulting in the connection at the nodes. The phenomenon of insufficient strength will affect the overall stability of the prefabricated buildi...
