Abstract
Description
Technical Field
[0001] This utility model relates to the field of door frame structure technology, specifically a thermal break door frame structure. Background Technology
[0002] Thermally broken door frame structures are a type of building door and window design that combines thermal insulation technology with a high-strength frame. They are primarily used to address the problems of high thermal conductivity and energy consumption associated with traditional metal doors and windows. Two layers of metal profiles are connected by a thermal break strip, forming a "thermal break" that blocks the heat conduction path. The thermal break strip effectively reduces the thermal conductivity of the metal, minimizing heat exchange between the indoor and outdoor spaces. With the continuous progress of the times and the development of the construction industry, residential and commercial office buildings are mostly high-rise buildings with dense populations, making fire safety paramount. In the event of a fire... The escape time for people is very short, so the doors in the middle and upper floors are all designed with fire protection. The fireproof and smokeproof doors commonly found on the market are mostly designed with fireproof and smokeproof technology in the door leaf components, while the door frames are the same as those commonly found on hillsides, such as integral metal door frames or split wooden door frames. When a fire occurs, the integral metal door frame is easy to conduct heat, which can cause people to be burned if they touch it. Although the wooden door frame is split, which effectively reduces its heat conduction performance, it is easy to be burned or the fire can be directed into the room. It also has defects such as complex structure and complicated installation.
[0003] The existing thermal break door frame is relatively complex to install. After the door frame component is damaged, it is not easy to disassemble it individually. The entire door frame structure needs to be disassembled, which is inconvenient and has poor installation convenience. Utility Model Content

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 This utility model provides a technical solution: a thermal break door frame structure, including a first frame 1, a second frame 2 and a third frame 3 with the same structure. The first frame 1 includes a first side plate 101 and a second side plate 102. PVC anti-collision strips are pasted on the outside of the first side plate 101 and the second side plate 102 to protect the edge of the door frame.
[0022] Two insert plates 104 are provided on one side of the first side plate 101, and two mounting frames 103 are provided on one side of the second side plate 102. The insert plates 104 are fitted inside the mounting frames 103. A barb or elastic protrusion is added to the end of the insert plate 104 to fit with the groove on the inner wall of the mounting frame 103 to prevent lateral displacement. A U-shaped groove is added at the opening of the mounting frame 103 to embed the sealing strip and improve the airtightness after insertion.
[0023] The first frame 1, the second frame 2, and the third frame 3 are all fitted with heat insulation strips 8. Each heat insulation strip 8 has a mounting groove 801 at both ends. The bottom of the mounting groove 801 is fitted with a base plate 4. Mounting plates 401 are set on the base plate 4, the first fixing plate 5, and the second fixing plate 6. The mounting plates 401 fit inside the mounting groove 801. The heat insulation strip 8 is a double-cavity or triple-cavity body, filled with polyurethane foam material to further reduce heat conduction. A serrated pattern is added to the inner wall of the mounting groove 801 to engage with the raised pattern on the surface of the mounting plate 401 to prevent the base plate 4 from shifting due to vibration.
[0024] A first fixing plate 5 and a second fixing plate 6 are provided at the connection of the first frame 1, the second frame 2 and the third frame 3. A connecting component 7 is provided at the top of the first fixing plate 5 and the second fixing plate 6. The first fixing plate 5, the second fixing plate 6 and the connecting component 7 are provided at both ends of the third frame 3. A slot 501 is opened on one side of the first fixing plate 5 and a slot 601 is opened inside one side of the second fixing plate 6. The two sides of the connecting component 7 are respectively fitted into the slot 501 and the slot 601.
[0025] The connecting component 7 includes a horizontal plate 701, a clamping plate 702 installed on one side of the horizontal plate 701, and a clamping post 703 installed on the side of the horizontal plate 701 adjacent to the clamping plate 702. The clamping plate 702 fits inside the clamping groove 501, and the clamping post 703 fits inside the clamping hole 601. The clamping post 703 adopts a threaded structure and is connected to a rotating expansion head at the end to adapt to clamping holes 601 of different depths. Cross reinforcing ribs are added to the back of the horizontal plate 701 to improve the load-bearing capacity, which is suitable for large-size door frames.
[0026] When installing the thermal break door frame structure, align the insert plate 104 of the first frame 1 with the mounting frame 103 of the second frame 2, and push it horizontally until the insert plate is fully embedded inside the mounting frame. Gently tap the contact surface with a rubber mallet to ensure a tight and seamless connection. Connect the second frame 2 and the third frame 3 in the same way to form the overall outline of the door frame. Push the thermal break strip 8 into the pre-installed groove on the inner side of the frame, ensuring that the mounting grooves 801 at both ends face outwards. The mounting grooves 801 should be aligned with the edge of the frame to facilitate the subsequent insertion of the base plate 4. Vertically insert the mounting plate 401 of the base plate 4. Insert the heat insulation strip directly into the mounting groove 801 until the base plate is flush with the frame. Check that the base plate is fully inserted to avoid warping. Place the first fixing plate 5 and the second fixing plate 6 inside the joint between the first frame 1 and the third frame 3, so that they fit against the two sides of the frame respectively. Adjust the position of the fixing plate by the opening direction of the slot 501 and the hole 601. Insert the clamping plate 702 of the horizontal plate 701 into the slot 501 of the first fixing plate 5. At the same time, align the clamping post 703 with the hole 601 of the second fixing plate 6 and press it into place to complete the overall assembly.
