Residential building system with cast-in-situ beam columns and prefabricated sandwich concrete wall panels and construction method

Abstract

The invention relates to a residential building system with cast-in-situ beam columns and prefabricated sandwich concrete wall panels and a construction method, and the construction process of a vertical load-bearing structure is as follows: mounting the prefabricated sandwich concrete wall panels in para-positions on an underbeam / foundation so as to leave certain vertical gaps at the joints between the prefabricated sandwich concrete wall panels respectively, leaving horizontal gaps between the prefabricated sandwich concrete wall panels and the underbeam / foundation, mounting clamp dies at the gaps and casting concrete in situ so as to fixedly connect inter-plate connecting columns and horizontal joints formed at the vertical gaps and the horizontal gaps respectively, cast-in-situ wall corner columns and the prefabricated sandwich concrete wall panels into a whole and further constitute the vertical force-bearing structure of the residential building system. By adopting the invention, the bearing capacity of a wall body and the integrity and the anti-seismic performance of the structure of the whole residential building system are significantly improved, the application of steel mesh frame polyphenyl sandwich panels in the load-bearing structures is powerfully pushed, and the economic and social benefits are significant.

Description

technical field [0001] The invention relates to a civil building structural system with high structural integrity and high seismic performance and a construction method for realizing the structural system. Background technique [0002] In order to achieve light weight and fire safety, the existing residential building structure system mostly uses polystyrene board or other materials as the sandwich panel of the wall. During the period, the development of building energy saving and wall reform was promoted, but because the building system still adopts the original building system and construction method, it is easy to appear that the splicing between the meshes is not firm and easy to loosen and deform, and the steel wire mesh on the board surface is sprayed with thicker cement mortar Large shrinkage, easy to crack, seriously affect the load-bearing and seismic performance of the wall and other issues. Contents of the invention [0003] In order to solve the above problems...
