[0001] This utility model relates to the field of door and window technology, and in particular to a heat insulation structure for door and window frames and sashes. Background Technology

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, mullions, and sashes. They can also be simply called aluminum doors and windows. Aluminum alloy doors and windows include those with aluminum alloy as the load-bearing member as the base material and those made of wood and plastic composites, also known as aluminum-wood composite doors and windows or aluminum-plastic composite doors and windows.

[0003] In aluminum alloy doors and windows, most common C-groove doors on the market use strip-type thermally insulated aluminum profiles. These profiles are composite materials formed by connecting inner and outer aluminum profiles with PA66 nylon thermal insulation strips, using mechanical strip insertion and roll forming processes to create thermal bridges. The thermal conductivity of PA66 nylon thermal insulation strips is approximately 0.25–0.30 W / (m·K). However, modern building energy conservation requirements for the thermal insulation performance of individual nodes in door and window frames and sashes are increasingly stringent, necessitating thermal insulation structures with better performance than PA66 nylon thermal insulation strips.

[0031] Please refer to Figures 1 to 3 This utility model embodiment provides a heat insulation structure for a door and window frame, which is disposed between two horizontally adjacent glass panes 10. Please refer to [reference needed]. Figure 3 The thermal insulation structure includes PE cotton 1, polyurethane foam strip 2, dummy mullion 3, dummy mullion end cap 4, and door and window frames 5. The glass 10 is preferably insulated glass. The sides of the glass 10 are pressed tightly against the PE cotton 1. The polyurethane foam strip 2 is covered by door and window frames 5 on both sides facing the indoor and outdoor areas. The polyurethane foam strip 2 and the door and window frames 5 press the PE cotton 1 tightly against the sides of the glass 10.

[0032] Please refer to Figure 3 PE cotton 1 and polyurethane foam strip 2 are provided on the opposite sides of two horizontally adjacent glass panes 10, and a pair of PE cotton 1 are symmetrically arranged and a pair of polyurethane foam strip 2 are symmetrically arranged; dummy mullions 3 and dummy mullion plugs 4 are located between a pair of polyurethane foam strips 2 and are distributed vertically.

[0033] The door and window frame insulation structure provided in this embodiment of the utility model utilizes polyurethane insulation material with a low thermal conductivity (as low as 0.062W / (m·K)) to significantly improve the insulation performance of the door and window frame insulation structure; and in conjunction with the insulation structure of PE cotton 1, false mullion 3, false mullion end cap 4 and door and window frame 5, the single-node insulation coefficient (K value) of door and window frame 5 can be optimized to a high level (up to 1.3W / (m2·K)).

[0034] Further, please refer to Figure 4 The dummy muzzle plug 4 faces two sides of the two polyurethane foam strips 2. One side is in contact with one side of the polyurethane foam strip 2, and the other side is separated from the other side by an intermediate seal 6. One side of the intermediate seal 6 is inserted into the dummy muzzle plug 4 through a concave-convex structure, and the other side is sealed to the polyurethane foam strip 2 by abutment. The concave-convex structure consists of a pair of symmetrical L-shaped plates protruding from the outer wall of the dummy muzzle plug 4 and a T-shaped structure protruding from the outer wall of the intermediate seal 6. The pair of L-shaped plates form a groove structure, and the T-shaped structure is inserted into the groove structure from the vertical direction to form an insertion fit. The groove structure restricts the movement of the T-shaped structure in the horizontal direction.

[0035] Further, please refer to Figure 4The door and window frames 5 on both sides, together with PE cotton 1 and dummy mullion plug 4, form a cavity 7 for accommodating polyurethane foam strip 2; the inner wall of the door and window frame 5 is provided with a protruding clip 51, preferably T-shaped, and the polyurethane foam strip 2 covers the clip 51; the molding method of polyurethane foam strip 2 is as follows: first, position the door and window frames 5 on both sides, then use two sealing plates to form a cavity with the door and window frames 5 on both sides, then inject polyurethane foam material into the cavity, and remove the sealing plates on both sides after the polyurethane foam material has hardened.

[0036] Further, please refer to Figure 3 or Figure 4 The door and window frame 5 has a cavity 53 inside, which is located on both sides of the polyurethane foam strip 2. The cavity 53 can reduce the efficiency of heat transfer from the indoor and outdoor environment to the polyurethane foam strip 2.

[0037] Further, please refer to Figure 5 The dummy mullion 3 is fixedly connected to the door and window frame 5. The dummy mullion 3 is fixed to the door and window frame 5 on both sides by screws 11. The dummy mullion 3 and the door and window frame 5 on both sides are sealed by pressing with soft sealing parts 8.

[0038] Further, please refer to Figure 6 and Figure 5 The false mullion 3 includes an outer frame 31, inner inserts 32, and a thermal insulation component 33. One pair of outer frames 31 are connected to the door and window frames 5 on both sides respectively, and the pair of inner inserts 32 are connected to the inner sidewalls of the outer frame 31. The outer frame 31 and the pair of inner inserts 32 form a space to accommodate the thermal insulation component 33. The thermal insulation component 33 can be made of PA66 nylon or polyurethane foam.

[0039] Further, please refer to Figure 3 A pressure plate 52 is provided on the side of the door and window frame 5 near the glass 10. A soft sealing element 8 is pressed between the pressure plate 52 and the glass 10. The soft sealing element 8 and the pressure plate 52 are detachably connected. The pressure plate 52 has a groove on the side facing the glass 10 into which the soft sealing element 8 can be inserted. A glass pressure line 9 is provided on the other side of the glass at the position corresponding to the pressure plate 52. A soft sealing element 8 is pressed between the glass pressure line 9 and the glass 10. The glass pressure line 9 is detachably connected to the door and window frame 5.

[0040] Specifically, please refer to Figure 7The detachable connection between the glass pressure line 9 and the door / window frame 5 is as follows: the door / window frame 5 is provided with a T-shaped groove 54 (specifically formed by a pair of symmetrical L-shaped plates), and the glass pressure line 9 is provided with a first claw 91 and a second claw 92 that extend into the T-shaped groove 54. The first claw 91 and the second claw 92 are respectively engaged with the opposite sides of the T-shaped groove 54. The glass pressure line 9 can be moved out of or inserted into the T-shaped groove 54 by vertical movement relative to the door / window frame 5. The second claw 92 forms an arc-shaped groove 921, and an elastic filler 93 is provided in the arc-shaped groove 921. The groove opening of the T-shaped groove 54 penetrates into the arc-shaped groove 921. When the groove opening of the T-shaped groove 54 squeezes the elastic filler 93, the static friction between the glass pressure line 9 and the door / window frame 5 can be increased. That is, the static friction that the glass pressure line 9 needs to overcome to slide vertically relative to the door / window frame 5 becomes larger. When there is no human intervention, the glass pressure line 9 and the door / window frame 5 can be kept relatively stationary, avoiding uncontrolled movement and abnormal noise.

[0041] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
