Modular anti-seismic connecting part

Abstract

The invention discloses a modular anti-seismic connecting part, and relates to the technical field of fabricated building seismic resistance. The modular anti-seismic connecting part comprises a firstbase and a second base which are connected in an inserted mode, the first base is further provided with a first inserting end, and a second inserting groove is correspondingly formed in the second base. The modular anti-seismic connecting part further comprises a limiting piece arranged on the end part of the first inserting end, a limiting groove correspondingly formed in the second inserting groove so as to accommodate the limiting piece and a first elastic piece arranged between the first base and the second base. The second base comprises a second upper base provided with the second inserting groove, a second lower base inserted into the second upper base and a second elastic piece connected between the second upper base and the second lower base. Flexible connection is mainly adopted, rigid connection is adopted as an auxiliary, earthquake force transmitted to the fabricated structure from an original wall body is relieved and weakened, and internal products in a functional areain the fabricated building are protected.

Description

technical field [0001] The invention relates to the field of anti-seismic technology of prefabricated buildings, in particular to a modular anti-seismic connecting part for connecting prefabricated wall panels and original walls. Background technique [0002] With the development of modern industrial technology, building houses can be manufactured in batches and in sets like machine production. As long as the prefabricated building components are transported to the construction site and assembled; and the buildings assembled by prefabricated components on the construction site are called prefabricated buildings. [0003] At this stage, in the functional areas inside buildings in earthquake-prone areas, such as the overall bathroom area, the traditional connection method between the prefabricated wall and the original building wall is generally a rigid connection method, and the method of enhancing seismic performance based on rigid connection Including: (1) enhancing the me...

Problems solved by technology

[0004] Among them, increasing the mechanical properties of the connecting parts generally includes increasing the size of the connecting parts and selecting materials with higher strength. Such methods will greatly increase the cost, making the cost increase unbearable; and increasing the number of connecting points will lead to an increase in the process. , the construction period becomes longer and labor costs increase; improving the rigid connection method will lead to complicated procedures, increased installation difficulty, lower efficiency, and even damage to the original wall, affecting building strength, and resonance

The most important thing is: none of the above methods can slow down the transmission of vibration force. When the seismic force is transmitted from the building to the prefabricated structure, it cannot weaken the vibration force, causing the prefabricated wall in the functional area to directly bear the seismic force. The time for the material of the type wall to reach the fatigue limit is shortened, shortening its service life
