Description

Technical Field

[0001] This utility model belongs to the field of door structure technology, specifically relating to a high-performance thermal break door structure. Background Technology

[0002] Traditional doors have aluminum alloy profiles installed on the side connecting to the door frame. Although these aluminum alloy profiles have the advantage of being lightweight, they can melt under high temperatures during a fire, thus affecting the overall strength of the door and making it difficult to guarantee safety in a fire. Therefore, it is very important to obtain a high-performance thermal break door structure that overcomes the above defects. Utility Model Content

[0003] To solve at least one of the above-mentioned technical problems, this utility model provides a high-performance thermal break door structure, comprising: a door body, wherein at least one profile frame is installed on the side of the door body near the door frame; and at least one frame inner sleeve is installed inside the at least one profile frame to ensure support strength.

[0004] The profile frame is made of aluminum alloy, and the inner sleeve of the frame is made of galvanized square tubing with a wall thickness of 2mm.

[0005] By using the above technical solution, galvanized square tubes are fixedly installed inside traditional aluminum alloy profiles. In the event of a fire, if the aluminum alloy melts, the galvanized square tubes, due to their high melting point, can provide support and increase stability while reducing material and cost.

[0006] The inner sleeve of the skeleton is fitted with hinges via hinge fixing plates and fasteners.

[0007] The door body includes two panels, front and back, with a heat insulation pad connected between the panels by fasteners. On the side of the heat insulation pad away from the door frame, a first graphite homogeneous heat insulation board, a fireproof door core board, and a second graphite homogeneous heat insulation board are sequentially filled.

[0008] Through the above technical solution, the heat insulation pad can connect the inner and outer sides of the door body, ensuring that the aluminum alloy frame provides final support for the door after it melts.

[0009] Two profile frames are installed on the side of the heat insulation pad near the door frame, and two nylon heat insulation strips are inserted between the two profile frames. Fireproof rock wool is filled between the two nylon heat insulation strips and between one of the profile frames.

[0010] Another profile frame is installed inside the existing profile frame. One panel is a flame-retardant wood panel, and the other panel is an aluminum panel. A steel plate is installed between the flame-retardant wood panel and the first graphite homogeneous insulation panel. A steel plate is installed between the aluminum panel and the second graphite homogeneous insulation panel.

[0011] Through the above technical solutions, the door body has the effects of being aesthetically pleasing, heat-insulating, and fireproof.

[0012] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure, which can improve the stability and strength of the door in the event of a fire and prevent it from melting at high temperature. Attached Figure Description
