Abstract

This utility model relates to the field of building door and window technology, and particularly to a thermally insulated hook structure with no cold bridge between indoor and outdoor surfaces. It includes an outdoor aluminum alloy profile, an indoor aluminum alloy profile, and a double-glazed unit installed in the middle. It also includes longitudinally installed thermal insulation strips A and B, a groove, and a cover plate. The groove is used for overlapping the aluminum alloy lift window and is fixed to the indoor aluminum alloy profile with screws. The cover plate covers and fastens to the thermal insulation strip A and the groove via a connecting assembly. In use, because the groove overlaps with polyamide nylon 66 material, and the cover plate covers and fastens to the thermal insulation strip A and the groove via the connecting assembly, heat transfer at this point is blocked. A continuous isotherm is formed between the groove, the cover plate, thermal insulation strips A and B, and the double-glazed unit, greatly improving the thermal performance of the door and window at the hook.

Description

Technical Field

[0001] This utility model relates to the field of building door and window technology, and in particular to a thermal insulation hook structure with no cold bridge between indoor and outdoor spaces. Background Technology

[0002] Aluminum alloy lift windows and other types of doors and windows that are opened and closed by sliding the movable sash (see...) Figure 1 The fans are connected by hooks and tongs. In the ordinary hook and tong connection method, although the indoor and outdoor aluminum profiles also use through-strip thermal insulation aluminum alloy profiles (a composite aluminum alloy profile with thermal insulation function formed by structural connection of inner and outer aluminum alloy profiles and the middle thermal insulation strip through processes such as tooth rolling, through-stripping, and rolling), complete thermal insulation is not achieved. The grooved overlap is a direct overlap between aluminum alloy profiles, which creates a thermal bridge between the indoor and outdoor parts at this point (see...). Figure 2 Heat can be rapidly transferred through cold bridges, causing frost and condensation to form on doors and windows in cold winters, thus affecting the comfort of using them. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model discloses a thermal insulation hook structure with no cold bridge between indoor and outdoor spaces.

[0004] The specific technical solution is as follows:

[0005] A thermally insulated hook structure with no cold bridge between indoor and outdoor surfaces includes an outdoor aluminum alloy profile, an indoor aluminum alloy profile, and a double-glazed window installed in the middle. It also includes a longitudinally installed outer thermal insulation strip A and an inner thermal insulation strip B, a groove, and a cover plate. The groove is used for overlapping the aluminum alloy lift window and is fixed to the indoor aluminum alloy profile by screws. The cover plate covers and fastens to the thermal insulation strip A and the groove through a connecting assembly.

[0006] The connecting assembly includes a hook-shaped protrusion, a triangular protrusion, and a claw B; the heat insulation strip A extends laterally outward with a pair of hook-shaped protrusions, and there are triangular protrusions on the groove. There are two claws B on the cover plate, and the cover plate is fastened to the heat insulation strip A and the groove by the claws B respectively.

[0007] It also includes a cover, in which two rectangular protrusions are arranged opposite each other in the groove. The cover has two claws A. The cover is fastened to the groove by the claws A and the rectangular protrusions, thus covering the screw.

[0008] The outdoor aluminum alloy profile and the indoor aluminum alloy profile are composite aluminum alloy profiles formed by rolling composite connection as the main frame.

[0009] The groove and the heat insulation strips A and B are all made of polyamide nylon 66 material, with 25% glass fiber added, and its thermal conductivity is 0.3 W / m·K.

[0010] The groove is attached to an outwardly extending hook at one end of the indoor aluminum alloy profile, which engages with the corner of the indoor aluminum alloy profile.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects:

[0012] When this utility model's thermal insulation hook is in use, the grooves are made of polyamide nylon 66 material and overlap each other. The cover plate, connected by a connecting assembly, covers and fastens onto the thermal insulation strip A and the grooves, blocking heat transfer at this point. A continuous isotherm is formed between the grooves, the cover plate, thermal insulation strip A, thermal insulation strip B, and the insulated glass, improving the thermal performance of the door and window at the hook. The door and window will not experience frost or condensation during winter use in cold regions, improving the comfort of using the doors and windows (see...). Figure 4 The absence of thermal bridges between the interior and exterior of the aluminum alloy doors and windows ensures true thermal insulation, improves their thermal performance, and makes them more heat-insulating.

It also includes a longitudinally installed outer thermal insulation strip A2 and an inner thermal insulation strip B3, a groove 5, and a cover plate 8. The groove 5 is used for the overlap of the aluminum alloy lift window and is fixed to the indoor aluminum alloy profile 4 by screws 6. The groove 5 and the indoor aluminum alloy profile 4 are equipped with a hook that extends outward at one end and engages with the corner of the indoor aluminum alloy profile 4. The cover plate 8 is fastened to the heat insulation strip A2 and the groove 5 by a connecting assembly; the connecting assembly includes a hook-shaped protrusion 201, a triangular protrusion 502 and a claw B801; the heat insulation strip A2 extends laterally outward with a pair of hook-shaped protrusions 201, the groove 5 has a triangular protrusion 502, and the cover plate 8 has two claws B801. The cover plate 8 is fastened to the heat insulation strip A2 and the groove 5 by the claws B801 respectively with the hook-shaped protrusions 201 and the triangular protrusions 502, which serves to improve the appearance.

[0020] It also includes a cover 7, in which two rectangular protrusions 501 are arranged opposite each other in the groove 5. The cover 7 has two claws A701. The cover 7 is fastened to the groove 5 by the claws A701 and the rectangular protrusions 501, covering the screw 6 and serving the purpose of aesthetic appearance.

[0021] The groove 5, along with the heat insulation strips A2 and B3, are all made of polyamide nylon 66 and contain 25% glass fiber. The thermal conductivity is 0.3 W / m·K, which is superior to that of aluminum alloy.

[0022] The groove, cover, thermal insulation strip A, thermal insulation strip B and the insulated glass form a continuous isotherm 10, which greatly improves the thermal performance of the door and window at the hook joint.
