GAT (GuAnTe) Exterior formwork cast-in-place concrete composite insulation system and construction technique thereof

Abstract

The invention discloses a GAT (GuAnTe) exterior formwork cast-in-place concrete composite insulation system and a construction technique thereof. The GAT exterior formwork cast-in-place concrete composite insulation system comprises a GAT composite insulation exterior formwork that is a dismantling-free formwork; concrete is cast between the GAT composite insulation exterior formwork and an interior formwork to form a cast-in-place concrete wall; the GAT composite insulation exterior formwork and the cast-in-place concrete wall are fixedly connected via connectors. The construction technique includes layout, setting out, cutting, mounting of special connectors, tying of rebars and pads, erection of the GAT composite insulation exterior formwork, erection of the interior formwork, fitting of tie bolts, erection of formwork wooden auxiliary battens and dual-steel-tube main battens, position adjustment for formwork fixation, casting of concrete, removal of the interior formwork and the main and auxiliary battens, splicing and internal and external corner anti-cracking treatment, leveling and mortar construction, and facing layer construction. The GAT exterior formwork cast-in-place concrete composite insulation system and the construction technique thereof have the advantages that the system herein has better thermal insulation, fire resistance, weather resistance, impact resistance and freeze thawing resistance and is good in safety, well applicable, economical and reasonable, engineering quality is guaranteed at the premise of construction period shortened, energy is saved,and emission is reduced.

Description

technical field [0001] The invention belongs to the technical field of building exterior walls, and in particular relates to a GAT external formwork cast-in-place concrete composite thermal insulation system and a construction process thereof. Background technique [0002] In the field of construction, in the past, the external wall usually adopts the masonry structure of blocks, and the external wall masonry is mostly composed of fly ash and blocks, which not only wastes resources and consumes energy, but also has the disadvantages of heat preservation, light weight, heat insulation, The problem of insufficient sound insulation performance cannot meet the requirements of the national building energy conservation. [0003] At present, in the prior art, external wall insulation boards are generally used, that is, a layer of insulation boards is pasted outside the concrete wall for insulation, but this insulation wall also has obvious disadvantages: firstly, the formwork needs...

Problems solved by technology

[0002] In the field of construction, in the past, the external wall usually adopts the masonry structure of blocks, and the external wall masonry is mostly composed of fly ash and blocks, which not only wastes resources and consumes energy, but also has the disadvantages of heat preservation, light weight, heat insulation, The problem of insufficient sound insulation performance cannot meet the requirements of the national building energy conservation

[0003] At present, in the prior art, external wall insulation boards are generally used, that is, a layer of insulation boards is pasted outside the concrete wall for insulation, but this insulation wall also has obvious disadvantages: firstly, the formwork needs to be used to pour the concrete wall , and then fix the insulation board, the construction process is cumbersome, and the demand for materials and labor is relatively large; secondly, the insulation performance of the insulation board is average, the energy-saving effect is poor, and the requirements for building energy conservation cannot be met; moreover, the wall insulation board of this kind Low hardness, poor weather resistance and impact resistance, easy to damage, easy to fall off under the influence of the natural environment, causing safety hazards, and finally this kind of insulation board is flammable and cannot meet the fire protection requirements
