Zero-carbon building cast-in-place concrete wall built-in heat preservation method and system

Abstract

The invention relates to a zero-carbon building cast-in-place concrete wall built-in heat preservation method and system, and aims to meet the requirement of zero-carbon building wall built-in heat preservation. A wall body is of an inner cast-in-place concrete layer, a middle heat preservation plate layer and an outer concrete protection layer structure; through-wall bolt airtight pipes are arranged between soil inner binding steel bar layers in a penetrating mode, and the cast-in-place concrete inner binding steel bar layers close to the heat preservation plate layer are preset at the cast-in-place concrete layer pouring position and the self-compacting concrete protection layer pouring position; a steel wire mesh interlayer is preset at the position of the self-compacting concrete protection layer, and a heat-bridge-free connecting piece used for fixedly arranging the heat preservation plate layer is connected between the cast-in-place concrete inner binding steel bar layer and the steel wire mesh interlayer; and through-wall bolt airtight pipes, through-wall bolts and sealing plugs at the two ends are arranged between the steel wire mesh interlayer of the cast-in-place concrete layer and the heat preservation plate layer and the cast-in-place concrete inner binding reinforcing steel bar layer of the self-compacting concrete protection layer in a penetrating mode. The system has the advantages of being simple in structure, convenient to construct, capable of guaranteeing the structural strength of all layers of the wall and the whole wall and good in heat preservation and heat insulation performance.

Description

Technical field [0001] The present invention relates to a condensating method, in particular, to a zero-carbon building, currently casting a concrete method and system. Background technique [0002] The prior art has a cash-in-situ concrete built-in insulation structure including concrete layer, insulation plate and concrete protection layer, the concrete layer, the insulation plate and the concrete protective layer are arranged from right to left, and a right steel sheet is provided in the concrete layer. A fixing member and a wire are provided on both sides of the thermal plate, and a longitudinal steel wire is provided in the concrete layer and the concrete protective layer, and the fixing member is connected to a longitudinal steel wire. The connection wire lateral setting The left steel sheet is provided in the concrete protective layer. [0003] The right steel wire and the left steel wire are composed of 1-3 sets of steel wire mesh. The fixing member includes a screw that ...

Problems solved by technology

However, the existing above-mentioned passive building wall-through bolt casings with airtight plugs can no longer meet the needs of zero-carbon buildings (ultra-low energy buildings, passive buildings, and near-zero energy buildings).

For example, compared with passive buildings in the past, zero-carbon buildings have significant changes in the weight and material of the insulation layer and the external additional layer, making the old wall-through bolt sleeves no longer applicable
