Description

Technical Field

[0001] The present invention relates to an installation process for zero-carbon building doors and windows, and particularly to an external-mounted door and window device and an installation process method therefor. Background Art

[0002] In ultra-low energy consumption buildings, especially zero-carbon buildings, highly energy-efficient passive windows are commonly used, and external-mounted installation of passive windows is relatively common.

[0003] In the existing external-mounted installation process of passive windows, several L-shaped fixing plates are fixed around the passive window by screws, and the L-shaped fixing plates are then fixed to the door and window holding frame through expansion anchor bolts. This installation process needs to meet the requirements of heat insulation and waterproof vapor barrier, and also needs to achieve heat bridge break treatment. Currently, the installation method using expansion anchor bolts does not achieve heat bridge break treatment, resulting in heat bridge effect, causing wall condensation, mildew and even dripping.

[0004] Existing passive windows also require light-shielding components. For example, blinds are used for light shielding. However, it is not suitable to install the blinds inside the external-mounted doors and windows because of the limited space of the opening. It is also inconvenient to install the blinds outside because the outside of the external-mounted doors and windows is a thermal insulation layer, which is not suitable for the blinds to take root. At the same time, heat preservation, airtightness and heat bridge break treatment need to be considered. Therefore, it is a certain challenge to install a louver curtain window on the basis of the external-mounted doors and windows. Summary of the Invention

[0005] The purpose of the present invention is to provide an external-mounted door and window device and an installation process method therefor, so as to achieve heat bridge break treatment for the installation of passive windows and composite installation of louver curtain windows.

[0006] To this end, the present invention provides an external-mounted door and window device, including a passive window and a window holding frame. A plurality of L-shaped connecting plates are provided on the window frame of the passive window, and a plurality of heat bridge break connecting seats are embedded in the window holding frame. The L-shaped connecting plates on the left, right and top sides of the passive window are respectively connected to the first heat bridge break connecting seats through bolts. Among them, a high-strength polyurethane spacer is provided between the L-shaped connecting plates and the heat bridge break connecting seats. It also includes an electric louver curtain window, located on the outdoor side of the passive window, including a window box and an electric louver curtain assembly. Among them, the lower edge of the window box is not lower than the top edge position of the window frame of the passive window, and a heat insulation spacer is provided between the back side of the window box and the wall structure surface. Among them, the left and right sides of the window box are provided with first adapter plates, and the first adapter plates are connected to the second heat bridge break connecting seats on the window holding frame through bolts. The back side of the window box is provided with a second adapter plate, and the second adapter plate is connected to the wall steel structure member through a heat bridge break connecting member.

[0007] The present invention starts from the window holding frame, solves the heat bridge break problem of the external-mounted installation of passive windows and the composite installation problem of louver curtain windows, and overcomes the technical problems in the construction of doors and windows in zero-carbon buildings.

[0008] In addition to the purposes, features and advantages described above, the present invention has other purposes, features and advantages. The present invention will be described in further detail below with reference to the drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0021] With reference to Figures 1 to 6 , the external hanging door and window device of the present invention includes a passive window 10, a window frame 20, and an electric louver window 30.

[0022] The passive window 10 uses a commercially available high - energy - saving external - mounted door and window finished product. On the top edge, left and right side edges of the window frame 11, a number of L - shaped connecting plates 12 are arranged. The L - shaped connecting plates are preferably hot - dip galvanized angle steels. The L - shaped connecting plates 12 are provided by the window frame manufacturer together.

[0023] The window form holding frame 20 is an integral casting structure or a split structure composed of four frame members, and is arranged in the window hole of the steel - structure wall. At the set positions of the top frame, left frame, and right frame of the window form holding frame 20, first heat - insulation bridge connecting seats 21 are embedded. The first heat - insulation bridge connecting seats are used for corresponding connection with the L - shaped connecting plates 12. At the set position of the top frame, a second heat - insulation bridge connecting seat 22 is also embedded.

[0024] The bottom frame of the window form holding frame 20 is connected with an anti - corrosion support wood 23 through expansion anchor bolts. The window frame is placed on the anti - corrosion support wood and leveled.

[0025] On the side of the L - shaped connecting plate 12 facing the external wall structure surface, there is a 10 - mm high - strength polyurethane cushion block, so as to conduct heat - insulation treatment between the L - shaped connecting plate 12 and the external wall structure surface on the premise of anti - deformation.

[0026] The outdoor waterproof and breathable film 13 is pasted around the window frame 11, and the indoor waterproof and moisture - proof film 14 is pasted around the window frame 11. The waterproof and moisture - proof film is bonded to the inner wall structure surface of the part between the window frame and the window opening, and the lower edge of the window frame is sealed, and secondary pasting is carried out at the position of the anti - corrosion support wood.

[0027] The electric louver curtain window 30 uses a commercially available finished product, which is composed of a window box 31, left and right side rails 32 extending out of the window box 31, and a louver curtain assembly 33. An electric control device is provided in the window box 31 to remotely control the louver curtain to rise, fall, face the light, and adjust against the light along the left and right side rails 32.

[0028] In the present invention, the electric louver curtain window 30 is suspended in front of the passive window, keeping a certain interval distance from the external wall structure surface. This space is provided with heat - insulation cushion blocks 34 or filled with heat - insulation materials. The window box 31 is placed above the top of the passive window, so as to ensure that the louver curtain does not block the view of the passive window when it is fully retracted.

[0029] The window box 31 is connected to the wall at three positions: the left and right sides and the top back side, thus solving the problem that it is difficult to install the louver curtain window on the external - mounted door and window.

[0030] Specifically, at the positions of the left and right sides of the window box 31 close to the top frame of the window form holding frame, first adapter plates 35 are provided. The first adapter plates 35 are connected to the second heat - insulation bridge connecting seats 22 on the window form holding frame through bolts. On the top back side of the window box 31, a second adapter plate 36 is provided. The second adapter plate 36 is connected to the wall steel structure member 40 through heat - insulation bridge anchor bolts 37. Here, the wall steel structure member belongs to the wall structure member of the steel - structure zero - carbon building, which is different from the concrete - structure wall.

[0031] The cable 38 of the electric louver window is introduced into the room from the wall penetration sleeve, and an airtight collar is provided at the pipe orifice of the wall penetration sleeve to maintain airtightness and heat insulation performance.

[0032] There are 10mm high-strength polyurethane pads between the first adapter plate 35 and the wall structural surface, and between the second adapter plate 36 and the wall structural surface. The rod body of the heat insulation bridge-breaking anchor bolt 37 can be made of fiberglass, and the heat insulation bridge-breaking treatment can be realized through the fiberglass material.

[0033] In the present invention, the heat insulation bridge-breaking connection seat is placed into the door and window holding frame by the embedded method, and the heat insulation bridge-breaking is realized through the heat insulation effect on the concrete matrix of the door and window holding frame.

[0034] In an embodiment, the heat insulation bridge-breaking connection seat includes an embedded base plate 1, a plurality of embedded studs 2, and embedded nuts 3. The embedded studs 2 are installed and fixed to the embedded base plate 1 through the embedded nuts 3. A heat insulation material layer 2a is sleeved on the plurality of embedded studs 2. The installation base plate 1 is a heat insulation member (such as fiberglass material, plastic alloy material) or the base plate 1a is coated with a heat insulation material layer 1b. The embedded nut 3 is composed of a plastic cap 3a and a metal insert 3b. In this way, the metal stud can be insulated from the concrete matrix, and thus the heat insulation bridge-breaking effect can be achieved.

[0035] Openings are provided at the non-stud connection parts of the embedded base plate 1 to make the concrete matrix as coherent as possible. The bonding strength between the heat insulation bridge-breaking connection seat and the concrete matrix is enhanced.

[0036] During the casting and molding of the door and window holding frame or components, this heat insulation bridge-breaking connection seat can be attached and positioned to the template 4 through bolts 5 and integrally cast with the concrete matrix 8.

[0037] Next, the installation process method of the external hanging door and window device of the present invention will be described.

[0038] The installation process method of the external hanging door and window device of the present invention includes the following steps S1 - S6.

[0039] S1. Fabricate the door and window holding frame and install it on the wall, and a plurality of heat insulation bridge-breaking connection seats are embedded in the door frame holding frame.

[0041] S3. Perform sealing treatment on the lower edge of the window frame. The outdoor waterproof and vapor-permeable membrane is pasted around the window frame, and secondary pasting is performed at the anticorrosive support wood. The indoor waterproof and vapor-barrier membrane is pasted around the window frame.

[0042] S4. Install the first adapter plate on the wall and the second adapter plate on the second heat insulation bridge connection base along the upper edge of the door and window frame.
