Permanent shuttering cast-in-place extra light concrete self-insulation composite wall body and construction technology

Abstract

The invention discloses a permanent shuttering cast-in-place extra light concrete self-insulation composite wall body and construction technology. The cross section comprises an inner side permanent shuttering layer, an outer side permanent shuttering layer, a welded reinforcement net rack and a cast-in-place extra light concrete layer, and wherein the permanent shuttering is manufactured of fiber-reinforced high-performance concrete. The construction technology is that prefabricating the welded reinforcement net rack and the permanent shuttering, mounting in onsite mode, placing extra light concrete, and forming a self-insulation composite wall body. The permanent shuttering not only serves as the shuttering, but also serves as a part of the structure to join common work, facilitates saving of a lot of construction shuttering, improves construction efficiency, and is a novel assembling integral type wall body structure which integrates structure, thermal insulation and shuttering into a whole. Technique applying the permanent shuttering cast-in-place extra light concrete self-insulation composite wall body and construction technology can achieve identical service life of building thermal insulation and structure, completely solves the problems of connection firmness and durability of thermal insulation layers and structural layers, facilitates engineering quality guarantee, saves engineering period, lowers cost, and promotes development of building industrialization.

Description

technical field [0001] The invention relates to the field of assembled integral wall structures in civil engineering structures. The permanent template cast-in-place ultra-light concrete self-insulation composite wall is a new type of thermal insulation and energy-saving wall integrating structure, thermal insulation, heat insulation, sound insulation and fire prevention. Body, including two parts of structural composition and construction technology. Background technique [0002] With the development of energy-saving building and wall insulation technology, the implementation of the energy development strategy of "energy saving priority" puts forward higher requirements for energy-saving technology. At present, a wall material pattern mainly composed of concrete blocks, supplemented by non-clay bricks and building panels has been formed, and has achieved remarkable social, economic and environmental benefits. However, in the process of using new wall materials, compared wi...
