Integrally cast demolding-free self-thermal insulation wall and construction method thereof

Abstract

An integrally cast demolding-free self-thermal insulation wall is composed of an outer wall body, an inner wall body and bead concrete filler. The outer wall body and the inner wall body are each formed by covering a steel wire gauze welded to a square steel frame with an inorganic hardening board. An outer wall body non-dismantling formwork is fixedly connected to outer wall body vertical keels, the upper portion and the lower portion of each vertical keel are of the identical length, and the vertical keels are transversely distributed at intervals. An inner wall body non-dismantling formwork is fixedly connected to inner wall body vertical keels between an upper slab and a lower slab of each floor. Horizontal connecting pieces and oblique connecting pieces are arranged between the inner wall body vertical keels and the outer wall body vertical keels. A non-dismantling formwork connecting piece is arranged between the outer wall body non-dismantling formwork and the inner wall body non-dismantling formwork. The thermal insulation wall can be integrally divided into the outer wall body and the inner wall body for construction, the outer wall body can be constructed together with a building body structure synchronously by the aid of a construction scaffold of a major structure, the inner wall body can be constructed indoors at any time after construction of the outer wall body is completed, construction is flexible and convenient, the occupied space of the scaffold is small, the construction efficiency is high, and the construction cost is low.

Description

technical field [0001] The invention relates to the structure of a building wall, in particular to a self-insulating wall without dismantling of formwork and a construction method thereof. Background technique [0002] Building walls are generally divided into: masonry walls, prefabricated slab-assembled walls, integral pouring walls, etc. Among them, the integral pouring walls can be divided into: turnover formwork, lifting sliding formwork, demolition-free Formwork, etc.; from the difference of wall insulation structure, it can be divided into: external wall insulation wall, interlayer insulation wall and self-insulation wall; self-insulation wall means that the wall material itself has insulation performance and can meet the requirements of national construction The energy-saving code requires that there is no need to separately design the insulation layer structure. [0003] The quality system standards for building walls are generally: earthquake resistance, impact res...

Problems solved by technology

In order to reduce construction difficulty, improve construction efficiency and reduce construction cost, it is especially hoped that the interior wall non-demolition formwork and exterior wall non-demolition formwork can be constructed separately in actual projects, and the exterior wall non-demolition formwork is installed independently first, and the main structure of the building is constructed After forming a complete exterior wall facade, the interior wall non-demolition formwork and the subsequent pouring process of the wall are installed in a timely manner according to the actual progress of the project, but so far no literature reports on this aspect have been seen; at the same time, the inorganic non-demolition The connection of the formwork is extremely poor, and it often cracks. How to make the connection between the inorganic non-demolition formwork of the wall and the steel keel in the wall unbreakable and never cracked has not been reported in the literature so far.
