Background

The passive house, namely the passive ultra-low energy consumption building, has been fully verified to have the characteristics of high comfort and ultra-low energy consumption after the first passive house is built in Darmstadt city in Germany in 1991 until now for more than 20 years.

In recent years, related policies of China are related to encourage the development of low-energy-consumption energy-saving passive buildings, which have strict regulations on energy consumption indexes and are roughly divided into several main standards of ultra-low energy consumption, near-zero energy consumption, zero energy consumption and the like. The entrance door used in the current market can not meet the requirements of all energy consumption assessment indexes due to the structure and the process, and needs to be redeveloped to meet the requirements.

The passive house has very strict requirements on the structure and performance of doors and windows, and the passive ultra-low energy consumption building door and window has the following requirements:

the maximum heat transfer coefficient (U value in the installation state) of the outer door and window is less than or equal to 0.8(W/m 2. K);

airtightness: under the condition of the indoor and outdoor positive and negative pressure difference of 50Pa, the average air exchange times per hour of the building is lower than 0.6;

therefore, the construction and the application of the reasonable door and window structural design 'passive house' have decisive influence, and the door and window frame section bar has important influence on the heat preservation performance of the building door and window.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a thermal bridge cut-off structure of passive door, its utensil keeps warm new can be strong, thermal-insulated effectual, the simple characteristics of structural assembly.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a passive door thermal break bridge structure comprising: the heat insulation board comprises a front board, a rear board, heat insulation filling and a binding;

the front plate and the rear plate are connected through a heat insulation plate; the heat insulation filling is arranged in an inner cavity formed by the front plate, the rear plate and the enclosure; the front plate is connected with the door frame through a hinge group; the wrapping edges are wrapped on the periphery of the heat insulation plate; and a sealing strip is also arranged between the edge cover and the rear plate.

Furthermore, the back plate is of a three-edge design, and the front plate cover is arranged on the opening side of the back plate.

Preferably, the two sides of the front plate are turned and rolled up, the heat insulation plate is fixed in the two side turned edges of the front plate through screws, and the rear plate is connected with the heat insulation plate and buckled on the front plate.

Preferably, the sealing strip is made of a low thermal conductive material.

Preferably, the heat insulation filling is filled with a hard polyurethane foam strip.

The utility model has the advantages as follows:

when the utility model works, the sectional door plate structure ensures the contact between the front plate and the rear plate and reduces the heat conduction; the wrapping edges are coated outside the heat insulation strips, so that the structural strength of the door body is ensured, and the stability of the joint of the door body is further protected; the sealing strips are adopted, so that the contact between the rear plate and the edge covering as well as the contact between the rear plate and the door frame are reduced, and the heat transfer is further reduced; overall structure is simple, convenient to detach and maintenance, and the two-way heat conduction of door plant and door plant, door plant and door frame is reduced to the thermal-insulated design of dual formula, improves the whole heat-proof quality of a body.
