Node connecting device for fabricated building structure

Abstract

The invention discloses a joint connecting device for a fabricated building structure, and relates to the field of fabricated buildings. The joint connecting device for the fabricated building structure comprises a stand column, wherein a square pipe seat is fixedly connected to the side wall of the stand column, a cross rod is movably inserted into a pipe cavity of the square pipe seat, two sets of fixing holes are formed in the top of the cross rod, fixing bolts are movably inserted into the fixing holes, the fixing bolts penetrate through the square pipe seat and the fixing holes to extend upwards and are in threaded connection with fixing nuts, a reinforcing rib is fixedly installed between the stand column and the cross rod, an ejector block is fixed to the top of the reinforcing rib, a first inserting column is fixed to the top of the ejector block, and two sets of locking holes are formed in the side wall of the first inserting column. When the joint connecting device for the fabricated building structure is used, the fabricated building structure can be conveniently assembled and connected with a node, after connection, the supporting effect on the joint is good, the strength is good, and when a user assembles the fabricated building structure, time and labor are saved, and rapid assembly is achieved.

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 assembled on site with prefabricated components. The advantages of this kind of building are fast construction speed, convenient construction, less restriction by climatic conditions, labor saving and improvement of construction quality. In recent years, the construction method of prefabricated buildings has attracted more and more attention and application. [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, an...

[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
