Technical Field
[0001] This utility model relates to the field of curtain wall technology, and in particular to an ultra-low energy consumption curtain wall and window micro-ventilation system. Background Technology
[0002] A curtain wall is a non-load-bearing exterior wall cladding for buildings, hung like a curtain, hence also called a "curtain wall." It is a lightweight wall structure with decorative effects commonly used in modern large and high-rise buildings. It consists of panels and a supporting structural system, and is a building envelope or decorative structure that can have a certain displacement capacity relative to the main structure or a certain deformation capacity, without bearing the load of the main structure.
[0003] Currently, most building curtain wall doors and windows focus too much on aesthetics, thus neglecting their practicality, especially their thermal insulation performance. Since curtain walls are often used in high-rise buildings, the temperature difference between day and night is large, and the buildings are cold in winter and hot in summer, especially in the Beijing-Tianjin-Hebei region of my country. Therefore, it is urgent for curtain walls to have good thermal insulation performance. Summary of the Invention

The EPDM sponge composite strips on the two first heat insulation layers are arranged opposite each other, and the distance between the two EPDM sponge composite strips gradually decreases from the inner door frame profile to the outer door frame profile. Both ends of the first nylon heat insulation strip, the second nylon heat insulation strip, and the EPDM sponge composite strip are inserted into the connecting grooves on the inner door frame profile and the outer door frame profile.
[0008] Preferably, the insulation layer includes an insulation rock wool layer and a vacuum insulation board layer arranged sequentially from the inner board to the outer board.
[0009] Preferably, the second heat insulation layer includes a third nylon heat insulation strip, a second flame-retardant polyurethane foam layer and a fourth nylon heat insulation strip arranged in parallel. The third nylon heat insulation strip is bonded to the EPDM sponge composite strip, and both ends of the third nylon heat insulation strip and the fourth nylon heat insulation strip are inserted into the mounting grooves on the inner door leaf profile and the outer door leaf profile.
[0010] Preferably, the two symmetrically arranged inner door frame profiles are a fixed inner door frame profile and a locking inner door frame profile, respectively. A locking block is provided on one side of the locking inner door frame profile, and a locking point is provided on the inner door profile corresponding to the locking block.

[0020] Example
[0021] like Figure 1 As shown, an ultra-low energy consumption curtain wall and window micro-ventilation system includes a hinged fixing part and an opening and closing part. The fixing part includes two symmetrically arranged inner door leaf frame profiles 1, two symmetrically arranged outer door leaf frame profiles 2, and a first thermal insulation layer 3 located between the inner door leaf frame profiles 1 and the outer door leaf frame profiles 2. The first thermal insulation layer 3 includes a first nylon thermal insulation strip 31, a first flame-retardant polyurethane foam layer 32, a second nylon thermal insulation strip 33, and an EPDM sponge composite adhesive strip 34 arranged in parallel. The two ends of the first nylon thermal insulation strip 31, the second nylon thermal insulation strip 33, and the EPDM sponge composite adhesive strip 34 are all inserted into connecting grooves on the inner door leaf frame profiles 1 and the outer door leaf frame profiles 2. The EPDM sponge composite adhesive strips 34 on the two first thermal insulation layers 3 are arranged opposite each other, and the distance between the two EPDM sponge composite adhesive strips 34 gradually decreases from the inner door leaf frame profile 1 to the outer door leaf frame profile 2.
[0022] The opening and closing part includes an inner panel 4, an outer panel 5, an insulation layer 6 located between the inner panel 4 and the outer panel 5, an inner door leaf profile 7 symmetrically arranged on both sides of the insulation layer 6 and fixedly connected to the inner panel 4, an outer door leaf profile 8 symmetrically arranged on both sides of the insulation layer 6 and fixedly connected to the outer panel 5, and a second heat insulation layer 9 located between the inner door leaf profile 7 and the outer door leaf profile 8. The insulation layer 6 includes a heat-insulating rock wool layer 61 and a vacuum insulation board layer 62 arranged sequentially from the inner panel 4 to the outer panel 5. The second heat insulation layer 9 includes a third nylon heat insulation strip 91, a second flame-retardant polyurethane foam layer 92, and a fourth nylon heat insulation strip 93 arranged in parallel, with both ends of the third nylon heat insulation strip 91 and the fourth nylon heat insulation strip 93 inserted into mounting grooves on the inner door leaf profile 7 and the outer door leaf profile 8. The third nylon thermal insulation strip 91 is bonded to the EPDM sponge composite strip 34. The bonding of the third nylon thermal insulation strip 91 and the EPDM sponge composite strip 34 can ensure the airtightness of the door when it is closed, thereby improving the thermal insulation performance of the curtain wall and window system.
[0023] Two symmetrically arranged inner door frame profiles 1 are designated as a fixed inner door frame profile 1 and a locking inner door frame profile 1, respectively. A locking block 10 is provided on one side of the locking inner door frame profile 1, and a locking point 11 corresponding to the locking block 10 is provided on the inner door profile 7. The locking block 10 and the locking point 11 enable a stable connection between the opening / closing part and the fixed part.
[0024] The two opposite sides of the fixed inner door frame profile 1 and the inner door profile 7 are fixedly connected to the two connecting ends of the hinge 12, which realizes the hinge connection between the fixed part and the opening and closing part. The fixed inner door frame profile 1 has a 90° limiting extension plate 13 on the side near the interior, which corresponds to the inner panel 4. The 90° limiting extension plate 13 can limit the opening angle of the opening and closing part. The inner door profile 7 has a first rubber strip 14 corresponding to the side of the inner door frame profile 1 near the interior, and the outer door frame profile 2 has a second rubber strip 15 corresponding to the outer door profile 8. The first rubber strip 14 and the second rubber strip 15 can realize the buffer function when the opening and closing part is closed, and at the same time, they can also realize the sealing performance between the opening and closing part and the fixed part after the opening and closing part is closed.
[0025] In use, the hinged connection between the fixing part and the opening and closing part enables the opening and closing of the doors and windows. When the doors and windows are closed, the first heat insulation layer 3, the heat insulation layer 6, the second heat insulation layer 9 and the rubber strip can ensure the heat insulation of the curtain wall door and window system and prevent heat exchange between the inner and outer rooms. The locking block 10 and the locking point 11 can lock the doors and windows. When open, the 90° limiting extension plate 13 can enable the doors and windows to open 90° for micro-ventilation.
[0026] Therefore, the ultra-low energy consumption curtain wall and window micro-ventilation system of this utility model with the above structure has good thermal insulation performance and can also realize micro-ventilation by opening inward.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
