[0021] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0022] Reference Figure 1-Figure 3The utility model provides an ultra-low energy consumption passive door and window combined thermal insulation frame, comprising:
[0023] Four prefabricated auxiliary frames 1, a ribbed hollow structure provided in the inner cavity of the prefabricated auxiliary frames 1, any two adjacent prefabricated auxiliary frames 1 are arranged perpendicular to each other and connected by an L-shaped corner code 2, and the two ends of the L-shaped corner code 2 are respectively plugged into the cavities of the two adjacent prefabricated auxiliary frames 1;
[0024] Among them, four prefabricated auxiliary frames 1 are connected end to end in sequence through L-shaped corner brackets 2 to form an auxiliary frame body, and the auxiliary frame body is embedded on the inner wall of the window.
[0025] The prefabricated auxiliary frame 1 in the utility model is made of foamed plastic, whose thermal conductivity is ≤0.067, and is extruded once in the factory, which can enhance the thermal insulation effect and improve the installation speed during construction. The prefabricated auxiliary frame 1 adopts a ribbed hollow structure, which can reduce its own weight and improve the structural strength of the entire auxiliary frame body. The prefabricated auxiliary frame 1 adopts a multi-hollow structure, and after the construction is completed, stagnant air is formed in the internal cavity. Since the thermal conductivity of stagnant air is about 0.023, the thermal insulation performance of the window after installation is further improved.
[0026] Furthermore, the prefabricated auxiliary frame 1 is connected to the L-shaped corner bracket 2 by self-tapping screws.
[0027] Furthermore, the end surface of the prefabricated auxiliary frame 1 is arranged as an inclined surface, and the inclination angle of the inclined surface is 45°.
[0028] The end of the prefabricated auxiliary frame 1 is set at a 45° bevel, and the L-shaped corner code 2 can be used to penetrate into its cavity, and then fastened with self-tapping screws to form an overall frame, which is then fixed in the template. After the concrete is poured and the template is removed, the auxiliary frame body is prefabricated in the concrete of the window. There are no concave and convex shapes around the window, which is more convenient for making templates.
[0029] After completing the installation of the frame body,
[0030] Further, a thermosetting polystyrene plate 3 is arranged on the inner wall outside the window chamber. The heat preservation effect can be enhanced by arranging the 50mm thick A-grade heat preservation material thermosetting polystyrene plate 3.
[0031] Furthermore, a waterproof vapor barrier membrane 4 is provided on the inner wall of the window chamber.
[0032] Furthermore, a waterproof vapor-permeable membrane 5 is provided on the inner wall outside the window chamber.
[0033] Furthermore, the waterproof vapor-permeable membrane 5 is arranged on the outside of the thermosetting polystyrene board 3 , and thermal insulation mortar 6 is arranged on the outside of the waterproof vapor-permeable membrane 5 and the waterproof vapor-isolating membrane 4 .
[0034] The thermal bridge effect is further blocked by pasting a waterproof vapor barrier membrane 4 indoors and a waterproof vapor permeable membrane 5 outdoors, and applying 20mm thermal insulation mortar 6 around the periphery.
[0035] The linear thermal bridge value of the left and right ports of the utility model is 0.152, and the thermal bridge value of the lower port is 0.175, which is far superior to the current traditional practice.
[0036] The directions or positional relationships indicated by “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention.
