A low-energy building parapet wall through-wall pipe insulation structure

Abstract

The invention provides a low-energy-consumption building parapet wall pipe insulation structure, which includes a parapet body, a wall hole provided on the parapet body, and at least one wall hole is provided on the parapet body. The wall-piercing pipe is arranged in the wall-piercing hole, and the circumference of the wall-piercing pipe is provided with a polyurethane foam layer and at least one set of pre-compressed sealing tapes. The outer side of the pre-compressed sealing band is fixed to the hole through the wall, and the pre-compressed sealing band has an annular structure. The beneficial effects of the invention are: the waterproof treatment of the wall-penetrating pipe of the passive house can be realized, the waterproof performance thereof can be guaranteed, and the stability of the heat preservation system can be guaranteed. The invention has reasonable design and convenient construction, not only solves the waterproof problem of the passive low energy consumption building, but also provides guarantee for the stability of the thermal insulation system of the passive low energy consumption building.

Description

technical field [0001] The invention relates to the technical field of building decoration, in particular to a low-energy-consumption building parapet wall-through-wall tube heat preservation structure. Background technique [0002] With the country's rapid promotion of energy conservation and emission reduction and the rapid development of building energy conservation, low-energy buildings have been vigorously promoted in my country, especially passive low-energy buildings. Passive low-energy buildings have entered my country for a relatively short period of time, resulting in many defects and deficiencies in the design of our country. [0003] For example, passive low-energy buildings have very strict requirements on waterproofing, and door and window connecting wires should be pasted around the openings of doors and windows to ensure the waterproof performance of passive low-energy buildings. Various voids appear, resulting in substandard waterproofing, especially at the...

Problems solved by technology

[0003] For example, passive low-energy buildings have extremely strict waterproof requirements, and door and window connecting wires should be pasted around the openings of doors and windows to ensure the waterproof performance of passive low-energy buildings. Various voids appear, resulting in substandard waterproofing, especially at the position where the parapet wall penetrates the wall pipe, but this is not considered in many drawings and designs, which leads to the situation that the passive house insulation system is prone to water ingress
