Composite bridge-cutoff structure passive house door

Abstract

The invention relates to a composite bridge-cutoff structure passive house door. The composite bridge-cutoff structure passive house door includes a composite bridge-cutoff structure frame (2) and a composite bridge-cutoff structure fan (1); the frame (2) and the fan (1) are hinged together; a contact part between the frame (2) and the fan (1) is step-shaped, and fireproof sound insulation sealing strips are arranged on the contact part. According to the composite bridge-cutoff structure passive house door, three sealing strips are arranged between the composite bridge-cutoff structure frame and the composite bridge-cutoff structure fan to form a plurality of circular air partitions; a good heat-insulation sound-insulation and environment protection effect is good; sealing strip installation grooves are formed in the fan frame; the sealing strips adopt fastening edges; the problem that precise sealing strip installation grooves are difficult to manufacture, and the sealing strips are difficult to install can be solved; and a heat insulation bridge-cutoff structure can be achieved.

Description

technical field [0001] The invention relates to the field of building doors, in particular to a door for passive houses with a composite broken bridge structure. Background technique [0002] A passive house is a master of various technical products. It is a house where the primary energy consumed by heating does not exceed 15 kW·h / (square meter. year) through sufficient renewable energy. Such a low energy consumption standard is achieved through high thermal and acoustic insulation, a highly airtight building exterior and renewable energy. [0003] Passive house is developing rapidly in economically developed countries. It has the advantages of heat insulation, sound insulation, anti-theft and fire prevention, etc. It is widely used in building doors. Passive house has just started in my country. The matching passive door is currently imported and expensive. At present, due to the high thermal conductivity of domestic steel doors, the sealing strip groove between the door a...

Problems solved by technology

[0003] Passive house is developing rapidly in economically developed countries. It has the advantages of heat insulation, sound insulation, anti-theft and fire prevention, etc. It is widely used in building doors. Passive house has just started in my country. The matching passive door is currently imported and expensive. At present, due to the high thermal conductivity of domestic steel doors, the sealing strip groove between the door and the door frame is difficult to deal with, and air leakage and air leakage cannot meet the requirements of sound insulation and heat insulation. Domestic wooden doors require a large amount of high-quality wood, the cost is high, and it is difficult to meet the requirements of sound insulation, Anti-theft requirements
