Description

Energy-saving door structure

Technical Field

The utility model relates to the technical field of energy-saving door structures, in particular to an energy-saving door structure.

Background

In recent years, related national policies encourage the development of low-energy-consumption energy-saving passive buildings, and energy consumption indexes of the buildings are strictly regulated. The heat transfer coefficient index of the low-energy-consumption energy-saving passive building is particularly strict. The existing entrance doors in the market cannot meet the energy consumption requirement because the structure is too simple, and the key indexes of heat preservation, sound insulation, air tightness and the like can only reach general levels by adopting a simple manufacturing process. A brand new structure needs to be developed again to meet the use requirement of the low-energy-consumption energy-saving passive building.

SUMMERY OF THE UTILITY MODEL

The utility model mainly provides an energy-saving door structure, and solves the problems that the prior art can not meet the energy consumption requirement and can only reach the common level on key indexes such as heat preservation, sound insulation, air tightness and the like.

In order to solve the technical problems, the utility model adopts the following technical scheme:

an energy-saving door structure comprises a door leaf and a door frame, wherein the door frame comprises a rear frame and a front frame detachably connected to the rear frame, and a separation material is arranged between the rear frame and the front frame; the door is characterized in that a plurality of steps are arranged on four sides of the door leaf, matching platforms are arranged on the rear frame and the front frame corresponding to the steps at the corresponding positions, a door frame sealing strip is arranged on the matching platform of the rear frame, and a door leaf sealing strip is arranged on the matching platform of the front frame. The steps on the rear frame and the front frame corresponding to the corresponding positions are provided with matching platforms, namely the steps on the rear frame and the front frame corresponding to the door leaf are provided with matching platforms after the door leaf is closed, and the specific reference is made to the attached drawings of the specification. According to the arrangement, after the door leaf and the door frame are closed, the corresponding steps and the matching platform form a closed cavity through the door frame sealing strips and the door leaf sealing strips which are correspondingly arranged, and air in the closed cavity can reduce heat transfer efficiency and improve sound insulation performance and sealing performance; meanwhile, the door leaf and the door frame are not in direct contact through the arrangement of the corresponding door frame sealing strip and the corresponding door leaf sealing strip, so that the heat transfer efficiency is reduced, the air tightness is improved, the sound insulation performance is improved, and the requirements of low energy consumption and energy conservation are met.

Furthermore, a clamping groove used for clamping the door frame sealing strip is arranged on the matching platform of the rear frame. By the arrangement, the door frame sealing strip can be conveniently installed.

Further, the device comprises at least three steps, and two matching tables of the rear frame and one matching table of the front frame. The arrangement at least can form two closed cavities, and compared with the situation of one closed cavity, the material waste is reduced under the situations of greatly improving the sound insulation performance, the sealing performance and the like.

Further, the separating material is made of heat insulating materials. When the passive entrance door is used, the heat insulation performance of the passive entrance door is improved, and heat is prevented from being transmitted between the indoor space and the outdoor space through the door frame. The door frame is made into a front part and a rear part, and a heat insulating material with low heat transfer coefficient is added between the front part and the rear part to form a special heat bridge-cut structure.

Further, the separation material is made of fireproof materials. When the passive fireproof door is used as a passive fireproof door, the heat is prevented from being transmitted between the indoor and the outdoor through the door frame in order to improve the fireproof and heat-insulating performance of the passive fireproof door. The door frame is made into a front part and a rear part, and fireproof materials (such as fireproof plates and the like) with low heat transfer coefficients are added between the front part and the rear part to form a special thermal bridge cut-off structure.

Furthermore, a reinforcing plate is arranged in the front frame. The reinforcing plate is arranged to strengthen the structural stability of the front frame, so that the front frame is not easy to deform.

Further, the door frame sealing strip and the door leaf sealing strip are made of elastic materials with low thermal conductivity. The material includes but is not limited to rubber material, polyurethane foam material, etc. The use effect can be improved by adopting the elastic material with low heat conductivity.

Has the advantages that: according to the arrangement, after the door leaf and the door frame are closed, the corresponding steps and the matching platform form a closed cavity through the door frame sealing strips and the door leaf sealing strips which are correspondingly arranged, and air in the closed cavity can reduce heat transfer efficiency and improve sound insulation performance and sealing performance; meanwhile, the door leaf and the door frame are not in direct contact through the arrangement of the corresponding door frame sealing strip and the corresponding door leaf sealing strip, so that the heat transfer efficiency is reduced, the air tightness is improved, the sound insulation performance is improved, and the requirements of low energy consumption and energy conservation are met.
