Fabricated self-insulation single face laminated shearing force wall board and casting method thereof

Abstract

The invention relates to a fabricated self-insulation single face laminated shearing force wall board and a casting method thereof. The casting method includes the steps that a laminated shearing force wall rebar framework and a basalt fiber reinforced polymer (BFRP) rib mesh piece in an outer wythe precast wall board are correspondingly bonded and manufactured, and insulation connecting parts arefixedly bonded on the rebar framework; and the rebar framework is placed on a protective layer cushion block of a casting framework platform, inner wythe wall board concrete is cast, the inner wytheprecast wall board after the inner wythe wall board concrete is cured to design strength is overturned by 180 degrees and moves to the upper part of another casting framework platform, the BFRP rib mesh piece is placed on a protective layer cushion block of another casting framework platform, outer wythe foam concrete is casted, the insulation connecting parts are pressed into the outer wythe concrete before initial set of the outer wythe foam concrete, and formwork stripping is conducted when the strength is reached. According to the fabricated self-insulation single face laminated shearing force wall board and the casting method thereof, a BFRP is treated as a bar material of the built-in mesh piece in the outer wythe wall board and a material of the connecting parts, the good thermal insulation performance of outer wythe foam concrete boards can be guaranteed, and stress requirements of the laminated wall board can also be met.

Description

technical field [0001] The invention relates to the field of construction, in particular to an assembled self-insulating single-sided laminated shear wall panel and a pouring method thereof. Background technique [0002] At present, my country is vigorously advocating the prefabricated building, a new building form. Compared with the cast-in-place structure, the prefabricated structure has the advantages of high production efficiency, stable component quality, energy saving and shortened construction period. It is an effective way to realize the industrialization of housing and construction. means. At the same time, with the rapid development of industrialization and urbanization in our country, and the continuous innovation of science and technology, new ideas and new countermeasures for building heat preservation and energy conservation have been continuously proposed to meet the requirements of the development of the times. We know that the most important heat exchange ag...

Problems solved by technology

We know that the most important heat exchange aggregate in the building structure is the wall of the building, but the thermal insulation wall commonly used at present, no matter the external thermal insulation wall or the internal thermal insulation wall, has its own defects and limitations. It is single and not suitable for prefabricated structural systems; while the prefabricated concrete sandwich insulation wall (inner sandwich insulation board), the connectors connecting the inner and outer leaf prefabricated wall panels in the wall must pass through the insulation layer, which will inevitably produce cold (hot) ) bridge effect
