Energy-saving building outer wall structure and construction method

Abstract

The invention discloses an energy-saving building outer wall structure and a construction method. The energy-saving building outer wall structure comprises frames, open grooves are formed in the sides, facing a wall body, of the frames, and outer edge parts are arranged on the outer sides of the open grooves; thin film layers are laid between the wall body and the frames, a plurality of through holes are formed in the portions, located on the outer sides of the open groove, of the interiors of the frames, connecting pipes are arranged in a matched mode through the through holes, expansion screws are arranged at the bottoms of the connecting pipes, and the expansion screws penetrate through the through holes and then are driven into the wall body; the ends, away from the wall body, of the frames are covered with veneers, and connecting screws are arranged between the veneers and the connecting pipes in a matched mode; a gap for filling concrete is formed between every two adjacent frames, reinforcing steel bars are embedded in the positions, corresponding to the gaps, of the wall body, and the gaps are sealed after the adjacent outer edge parts are combined; and foaming plates are formed after a foaming agent is sprayed into the frames. The structure can be quickly disassembled and assembled, and has a better heat preservation effect.

Description

technical field [0001] The invention relates to an energy-saving building exterior wall structure and a construction method. Background technique [0002] The thermal insulation effect of the external wall can effectively keep the cold when the room is cooled in summer, reduce the temperature exchange between indoor and outdoor, avoid the repeated start-up of the air conditioner, and achieve the technical effect of energy saving. In winter, indoor human activities or heating , will generate heat, through the insulation of the external wall, the heat dissipation can be reduced, the indoor heat can be effectively accumulated, the energy consumption of frequent heating can be reduced, and the technical effect of energy saving can be achieved. [0003] There are mainly two types of external wall insulation in the prior art. One is to install insulation boards. In this way, due to problems such as gaps between insulation boards and looseness of insulation boards, the insulation e...

AI Technical Summary

Problems solved by technology

[0003] There are two main types of external wall insulation in the prior art. One is to install insulation boards. In this way, due to the gap between the insulation boards and the looseness of the insulation boards, the insulation effect will be reduced.

At the same time, it is not convenient for later maintenance

The second is to spray the foaming agent, which forms a filling between the wall and the veneer by spraying the foaming agent. Although this method can effectively avoid heat loss, the foaming agent cannot be removed after spraying and molding, so , when the external wall is re-constructed later, the demolition work is very troublesome
