Formwork-free cast-in-place lightweight thermal insulation wall formwork, thermal insulation wall and construction method thereof

Abstract

Disclosed are a non-dismantling die cast-in-place lightweight thermal insulation wall formboard, a thermal insulation wall and a construction method thereof. The formboard comprises an inner formboard unit, an outer formboard unit and opposite-drawing connectors connecting the formboard units; the inner formboard unit comprises a formboard frame, steel bar grid frames connected between inner circles of the formboard frame, steel bar clamps connected to the cross points of the steel bars of the steel bar grid frames and a formboard core filling the inner side of the formboard frame; the inner formboard unit and the outer formboard unit are the same in structure and are connected at two ends of the opposite-drawing connector symmetrically; the steel bar clamps of the inner formboard unit and outer formboard unit are corresponded horizontally and are connected through the opposite-drawing connectors. The thermal insulation wall is simple in structure, by means of the double-layer wall formboard, the wall thickness consistence is guaranteed, the strength performance requirements are met, the thermal insulation wall is convenient to construct, the matching bar, core column and tie beam arrangement procedures are omitted, construction cost is lowered, constructing efficiency is improved, and the formboard can widely applied to wall construction.

Description

technical field [0001] The invention relates to a wall template, a wall and a construction method thereof. Background technique [0002] Recently, a formwork-free cast-in-place lightweight thermal insulation wall has appeared. The main body is composed of a wall body, a leveling layer, and a crack-resistant protective layer. It is combined with cast-in-place concrete, in which the cast-in-place concrete is cast between the inner and outer insulation boards, and bonded with the insulation boards on both sides to form a whole; the inner and insulation boards must be set relatively parallel and the two A certain gap must be reserved between them, and they can be connected by specific tension connectors to ensure the stability of the formwork on both sides and the stability of the gap size during the concrete pouring process. In this type of formwork-free cast-in-place lightweight thermal insulation wall system, since the inner and outer thermal insulation boards are also used ...
