Heat preserving and energy saving structure for outer wall of old house and modification construction technology thereof

Abstract

The invention relates to a heat preserving and energy saving structure for an outer wall of an old house and a modification construction technology thereof. The structure comprises multiple heat preserving plates, grid cloth and anti-crack mortar, wherein the heat preserving plates are bonded to the surface of the outer wall, the grid cloth is bonded to the sides, away from the outer wall, of theheat preserving plates, and the anti-crack mortar covering the grid cloth. Connecting parts are detachably connected to the peripheries of the heat preserving plates. A filling groove is formed between every two adjacent heat preserving plates through two connecting parts. Seam filling blocks made of the same material as that of the heat preserving plates are arranged in the filling grooves. The seam filling blocks are filled between every two adjacent heat preserving plates, the seam filling blocks are fully filled into gaps between every two heat preserving plates, the gaps between every twoadjacent heat preserving plates are reduced, and the heat preserving effect of the outer wall is improved.

Description

technical field [0001] The invention relates to the technical field of renovation of the outer walls of old houses, in particular to a thermal insulation and energy-saving structure of the outer walls of old houses and a renovation construction process thereof. Background technique [0002] The transformation of old houses is an important task in urban construction planning. In the renovation process of old houses, it is extremely important for the thermal insulation of the outer walls to reduce the heat loss of the outer walls and provide a good living environment for the residents in the old houses. [0003] At present, most of the external wall insulation adopts the method of laying thermal insulation boards. The thermal insulation board, mesh cloth and mortar layer are bonded in sequence on the surface of the external wall. During the process of laying the thermal insulation board, the thermal insulation board is cut into several Block shape, arrange and bond multiple c...

AI Technical Summary

Problems solved by technology

However, during the construction process, it is not easy to position and align between two adjacent insulation boards, and the compression effect of the joints only by expansion bolts and plastic gaskets is poor, and the gap between the joints of the two insulation boards is also poor. Larger, affecting the quality of insulation
