External cast-in-situ heat preservation wall and construction method thereof

Abstract

The invention relates to heat preservation structures for building walls, in particular to an external cast-in-situ heat preservation wall and a construction method thereof. The external cast-in-situheat preservation wall comprises a wall body and multiple rectangular heat preservation plates arranged on the surface of the wall body, steps penetrating through the edges of the heat preservation plates are arranged at the edges of the outer sides of all the heat preservation plates, and accordingly every two adjacent heat preservation plates are in contact to form a groove; a spliced gap between every two adjacent heat preservation plates is located in the corresponding groove, the wall further comprises connection plates matched with the grooves, multiple connectors are arranged on the connection plates, one end of each connector is fixedly connected with the corresponding connection plate, and the other end of each connector penetrates through the bottom of the corresponding groove and then extends into the wall body, so that the connectors are fixed in the wall body formed through pouring. The heat preservation plates are stably limited on the surface of the wall body through theconnection plates, so that the heat preservation plates are stably installed, do not easily fall off and are not easily damaged; the spliced gap between every two adjacent heat preservation plates isclosed inside, so that the service life of the heat preservation plates is long, few construction steps of the external cast-in-situ heat preservation wall are needed, and operation is easy.

Description

technical field [0001] The invention relates to a building wall thermal insulation structure, in particular to a cast-in-place external thermal insulation wall and a construction method thereof. Background technique [0002] Adding an insulation layer on the wall of the building is beneficial to avoid the mutual diffusion of heat inside and outside the wall, avoiding the occurrence of cold and heat bridges in the weak parts of the building's outer wall envelope, and effectively reducing the energy consumption of air conditioners. At present, in buildings It has become an important measure for energy saving and emission reduction to set insulation layer on the wall body of buildings. [0003] The existing insulation layer is generally installed by pasting or anchor bolt connection. The insulation layer using the pasting method is affected by the flatness of the wall surface, and a virtual connection structure is likely to appear between the wall surface and the insulation lay...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to: install the thermal insulation layer of the existing building wall by pasting or anchor bolt connection, and do not deal with the splicing gap of the thermal insulation board, which will cause the thermal insulation board to fall off easily and fail, and affect the service life of the thermal insulation layer. problem, to provide a cast-in-place external thermal insulation wall and its construction method that is stable in installation and not easy to immerse in rainwater or air in the gap
