Prefabricated filling wall system with hollow thermal insulation structure and construction method thereof

Abstract

The invention discloses a prefabricated filling wall system with a hollow thermal insulation structure and a construction method thereof. The prefabricated filling wall comprises a hollow cavity box structure and a concrete shell layer, wherein the concrete shell layer is poured on the outer side surface of the hollow cavity box structure. The hollow cavity box structure comprises cushion blocks,a steel bar mesh frame, a hollow box body and partition boards, wherein the hollow box body is formed by surrounding of box wall plates; and the partition boards are arranged in a hollow box body in parallel and at intervals. At least four cushion blocks are arranged on the front and rear box wall plates of the hollow box body. The steel bar mesh frame is formed by tie tying of a transverse steelbar and a vertical steel bar, and is laid on the hollow box body. Holes are arranged on the cushion blocks, wherein the transverse steel bar can penetrate through the hoes. A groove is formed by the left and right side box wall plates of the hollow box body and the front and rear side box wall plates of the hollow box body. The prefabricated filling wall has simple structure, convenient construction, good thermal insulation and sound insulation performance, and little influence of human factors on the construction. Flexible connection is used for effectively suppressing cracks in the filling wall.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a prefabricated filling wall system with a hollow thermal insulation structure and a construction method thereof. Background technique [0002] At present, some small hollow blocks or perforated bricks are usually used for building frame-filled walls, which are connected with the main structure through a certain number of tension bars, but this structure has certain defects. In terms of structural mechanical performance, due to the quality of the masonry, the overall performance of the infill wall is poor. Under the action of earthquakes, the infill wall is prone to slip damage of the masonry mortar layer. At the same time, the masonry mortar is prone to shrinkage during the air-drying process, causing the filling wall to settle and separate from the frame beam, resulting in cracks. [0003] In terms of the seismic performance of the structure, the infill wall...
