Novel prefabricated primary and secondary beam composite connecting node and connecting method thereof

Abstract

The invention discloses a novel prefabricated primary and secondary beam composite connecting node. The node comprises a primary beam. A trench is arranged in the middle position of the right side ofthe primary beam. The middle position in the interior of the trench is fixed with channel steel. Positions, located on left and right sides of the channel steel, in the interior of the trench are bothfixedly connected with secondary beams. Interiors of the secondary beams are fixedly connected with steel bars. One ends, approaching the middle of the trench, of the steel bars penetrate through outsides of the secondary beams. Surfaces on two sides of the channel steel are equipped with steel bar holes. One ends, located in the interior of the channel steel, of the steel bars are in threaded connection with nuts. The middle position outside the channel steel is equipped with a grouting circular hole. The node relates to the technical field of building beams. With the novel prefabricated primary and secondary beam composite connecting node and the connecting method thereof, improvements are made on assembly type primary and secondary beam connection. The connection efficiency of the primary beam and the secondary beams is increased. The wet construction amount is reduced. Assembly efficiency and productivity are improved. Safety and quality are enhanced. The purpose of driving modernization of the building industry is fulfilled.

Description

technical field [0001] The invention relates to the technical field of building beams, in particular to a novel prefabricated primary and secondary beam composite connection node and a connection method thereof. Background technique [0002] Supported by the support, the external force borne is mainly lateral force and shear force, and the component mainly deformed by bending is called a beam. The beam supports the entire weight of the components in the upper frame of the building and the roof, and is the most important part of the upper frame of the building. There are different names depending on the specific position, detailed shape, and specific functions of the beam. Most of the beams are oriented in line with the cross-section of the building. [0003] Beams are structural members that bear vertical loads and are mainly subjected to bending. Beams are generally placed horizontally to support the slab and bear various vertical loads from the slab and the self-weight ...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides a new type of prefabricated primary and secondary beam composite connection node and its connection method, which solves the problem that the current main and secondary beams are connected by pasting cement mortar, thereby increasing the amount of wet work, and in this way The connection method is easily affected by the environment, and the service life of the connection is short, so the safety performance of the node connection is low, which is not conducive to the development of building modernization.
