Reinforced building block filling type wall body applied with prepressing stress and construction method

Abstract

The invention discloses a reinforced building block filling type wall body applied with prepressing stress and a construction method, and belongs to the technical field of seismic resistance of building structures. The problems existing in a traditional filling type wall body are solved. The wall body comprises pieces of vertical reinforced rebar laid in piled hollow building blocks, a transversesteel plate is arranged on the upper surface of the hollow building block of the top piled layer, nuts are arranged on the portions, located on the upper side of the transverse steel plate, of the pieces of vertical reinforced rebar, and prepressing stress is applied to a filling type wall by the transverse steel plate under the effect of the nuts; the method comprises the steps that when the hollow building blocks are piled to about half of the filling type wall, the pieces of vertical reinforced rebar are inserted in the hollow building blocks after piling is completed, and in the continuouspiling process, the hollow building blocks located at the pieces of vertical reinforced rebar penetrate through the upper ends of the pieces of vertical reinforced rebar for piling; when the hollow building blocks of the second last layer are piled, the transverse steel plate is connected with the pieces of vertical reinforced rebar; the reinforced building block filling type wall body is used for seismic resistance of building structures.

Description

technical field [0001] The invention belongs to the field of anti-seismic technology of building structures, and in particular relates to a precompressed reinforced block filled wall body and a construction method. Background technique [0002] Filled wall is a common form of wall in building structures at present. The traditional filled wall has poor ductility and low bearing capacity. Brittle damage or even collapse, causing a lot of economic losses and casualties. [0003] Some new infill walls currently proposed completely abandon the characteristics of traditional infill walls, but are difficult to be popularized in actual projects due to high cost and difficult construction; while some improved infill walls maintain the characteristics of traditional infill walls, but often On the premise of sacrificing part of the performance of the infill wall, it is difficult to simultaneously improve the seismic capacity of the infill wall inside and outside the plane. An ideal i...
