A method for heat preservation, energy saving and water drainage of building exterior walls

Abstract

The invention discloses a method of thermal insulation, energy saving, water draining, and waterproofing of a building external wall. The method of thermal insulation, energy saving, water draining, and waterproofing of the building external wall comprises the nine steps that 1, a square fixing frame with a size matched with the building external wall is pre-prepared according to the size of a building external wall; and 2, a plurality of mounting holes are formed in the outdoor surface of the building external wall by using an electric drill. According to the method of thermal insulation, energy saving, water draining, and waterproofing of the building external wall, workload of edge trimming is greatly reduced, thus the work efficiency is improved, the construction quality is improved atthe same time, when a rigid foam polyurethane thermal insulation layer needs to be dissembled in later period, the overall structure can be dissembled by pulling a square fixing frame, compared withthe prior art, the method has better practicability, damp on the indoor surface of building external wall can be effectively prevented, cracking due to uneven heating of the building external wall canbe prevented, the method plays a positive role in indoor energy saving and is especially suitable for thermal insulation and energy saving of the building external wall in later period, and the disadvantage of lacking measurement of existing building external wall thermal insulation and energy saving transformation in later period is compensated.

Description

technical field [0001] The invention relates to the field of building technology, more specifically, it relates to a method for heat preservation, energy saving and water drainage of building exterior walls. Background technique [0002] Existing methods for thermal insulation, energy saving and drainage of external walls of buildings require extensive trimming of the edges, and the workload is large, which affects work efficiency and construction quality. It is very troublesome and has poor practicability. Secondly, the thermal insulation and waterproof performance of the insulation layer is poor, the bond is not firm, and the wind resistance performance is poor. Moisture also often leads to cracking due to uneven cold and heat of the building's outer wall, which has little effect on indoor energy saving. In addition, it has no finish layer, which seriously affects the appearance of the building's outer wall. It does not strictly follow the building's outer wall insulation ...

[0002] Existing methods for thermal insulation, energy saving and drainage of external walls of buildings require extensive trimming of the edges, and the workload is large, which affects work efficiency and construction quality. It is very troublesome and has poor practicability. Secondly, the thermal insulation and waterproof performance of the insulation layer is poor, the bond is not firm, and the wind resistance performance is poor. Moisture also often leads to cracking due to uneven cold and heat of the building's outer wall, which has little effect on indoor energy saving. In addition, it has no finish layer, which seriously affects the appearance of the building's outer wall. It does not strictly follow the building's outer wall insulation and energy saving requirements Construction according to the design standards cannot guarantee the construction quality and the performance of thermal insulation and energy saving and water discharge, and cannot guarantee the smooth acceptance in the later stage, and it is not suitable for the later thermal insulation and energy saving renovation of the building's outer walls, resulting in the lack of effective measures for the later thermal insulation and energy saving renovation of the building's outer walls
