[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Figure 1 The structure of the assembled curtain wall disclosed in the embodiment of the present invention is shown (a single unit structure, and a plurality of unit structures are spliced ​​together to form an integral curtain wall).

[0022] like Figure 1 and 3 As shown, the side frame 11 structure includes two vertically arranged longitudinal beams 112, two transverse beams 111 are transversely connected between the two longitudinal beams 112 to form a rectangular frame, two layers of panels 115 are arranged between the rectangular frame and the middle frame 12, buffer connectors 113 are arranged at the contact position between the panels 115 and the rectangular frame and the middle frame 12, and a limiting buffer 114 is arranged between the two layers of panels 115.

[0023] A sealed space is formed between the two panels 115 by the limiting buffer 114 , and the air in the sealed space is removed by vacuuming, so that a vacuum environment is formed in the sealed space.

[0024] The buffer connector 113 and the limit buffer 114 are made of rubber and adopt the existing technology, and the principle thereof will not be described in detail here.

[0025] In order to achieve the function of adjusting the temperature when the temperature rises, the present invention improves the existing prefabricated curtain wall structure, including a frame structure 1 consisting of a single middle frame 12 and two side frames 11 respectively arranged on both sides of the middle frame 12, and an air flow channel 121 is arranged inside the middle frame 12, and at least one interface 122 is provided at both ends of the middle frame 12.

[0026] by Figure 1 Taking the viewing direction as an example, during the installation of the prefabricated curtain wall provided by the present invention, the interiors of the two adjacent prefabricated curtain walls on the left and right are not connected, while the interiors of the two adjacent prefabricated curtain walls on the top and bottom are connected to each other through the interface 122.

[0027] like Figure 1 As shown, in order to enhance the air tightness of the connection between the two adjacent assembled curtain walls, sealing gaskets are provided on the end surfaces of the middle frame 12 at both ends close to the interface 122 .

[0028] like Figure 3 As shown, in the above structure, after the curtain wall construction is completed, only the upper and lower adjacent prefabricated curtain walls of the assembled prefabricated curtain walls are connected internally, while the left and right adjacent prefabricated curtain walls are not connected internally.

[0029] The advantage of doing this is that in addition to improving redundancy and avoiding failure of the temperature control function due to damage to the prefabricated curtain wall, it also allows the curtain wall to open internal channels automatically when the temperatures in different areas are different, thereby achieving the effect of temperature control for different areas.

[0030] like Figure 3 As shown, since the middle frame 12 is provided with an interface 122, when the interface 122 is not provided with a valve, the air flow channel 121 inside the prefabricated curtain wall always remains connected, so that when the temperature is low, the internal air flows in the prefabricated curtain wall, resulting in heat loss, which will cause the building to need additional energy to maintain the indoor temperature, resulting in energy loss. When the temperature is high, the internal air flow can reduce the temperature of the curtain wall, thereby reducing the energy consumption of the building.

[0031] like Figure 2 and 4 As shown, in order to achieve normal use at lower or higher temperatures and reduce building energy consumption, a non-powered valve box 2 is provided in the interface 122 to control the connection state between two adjacent intermediate frames 12 .

[0032] Figures 5 to 7 The structure of the movable valve plate component 23 at several different openings of the unpowered valve box 2 is shown.

[0033] Among them, the unpowered valve box 2 includes a guide shell 21 arranged in the interface 122, wherein the two ends of the guide shell 21 have openings, and movable valve plate components 23 are respectively provided on both sides of the interior of the guide shell 21 near the openings. The movable valve plate component 23 is connected to a driving unit 22, and the driving unit 22 is used to drive the movable valve plate component 23 to open or close.

[0034] like Figure 5 As shown, at this time, the movable valve plate component 23 is in a closed state, and the unpowered valve box 2 is in a closed state. This indicates that the temperature is relatively low, and the air flow channel 121 inside the assembled curtain wall remains in a closed state. After the air inside is heated, the building is insulated and heat-collected, thereby reducing the energy consumption of the building when the temperature is low.

[0035] like Figure 6 As shown, at this time, the movable valve plate component 23 is in a semi-open state, and the unpowered valve box 2 is in a semi-open state. This indicates that the temperature has risen, and the air flow channel 121 inside the prefabricated curtain wall remains connected. After the air inside is heated, the hot air floats up and drives the cold air below to enter the middle frame 12, thereby achieving the effect of cooling the prefabricated curtain wall and improving the temperature comfort inside the building.

[0036] like Figure 7As shown, at this time, the movable valve plate component 23 is in a fully open state, and the unpowered valve box 2 is in an open state. This indicates that the temperature is relatively high, and the air flow channel 121 inside the prefabricated curtain wall remains connected. After the air inside is heated, the hot air floats up and drives the cold air below to enter the middle frame 12, thereby achieving the effect of cooling the prefabricated curtain wall and reducing the energy consumption of the building when the temperature is relatively high.

[0037] like Figure 8 and 9 As shown, the movable valve plate component 23 includes an orifice plate a231 and an orifice plate b232 stacked together, wherein the holes on the orifice plates a231 and b232 are of the same size and are staggered in position, and the driving unit 22 has a linear telescopic driving end, which is connected to the orifice plate b232, driving the holes on the orifice plate b232 to coincide or not coincide with the holes on the orifice plate a231, wherein the orifice plate a231 is fixedly arranged on the side close to the opening of the guide shell 21, and a slide groove 211 is provided on the side wall away from the opening of the guide shell 21, and both sides of the orifice plate b232 are engaged in the slide groove 211, and move along the length direction of the orifice plate a231 under the drive of the driving unit 22.

[0038] like Figure 8 and 9 As shown, the driving unit 22 includes a limiting guide shell 221, and a linear telescopic driving end is arranged inside the limiting guide shell 221, wherein the linear telescopic driving end includes an elastic capsule 222 arranged inside the limiting guide shell 221, and the elastic capsule 222 is filled with a filling material 223 with thermal expansion and contraction properties, and a guide plate 224 is provided on the side of the elastic capsule 222 close to the opening of the limiting guide shell 221, and a connecting plate 225 is provided on the side of the guide plate 224 close to the opening of the limiting guide shell 221, and the connecting plate 225 is perpendicular to the top of the limiting guide shell 221, and the top of the limiting guide shell 221 has a groove for accommodating the passage of the connecting plate 225, and the connecting plate 225 is connected to the orifice plate b232.

[0039] The elastic capsule 222 may be made of a flexible material that matches the shape of the position-limiting guide shell 221 . In the present embodiment, the elastic capsule 222 is made of a rubber bellows that matches the shape of the position-limiting guide shell 221 .

[0040] The filler 223 has the property of thermal expansion and thermal contraction. In this embodiment, glycerin is selected as the filler 223.

[0041] The state change process of the elastic capsule 222 is as follows: After being heated by the rising temperature, the filling material 223 expands, and during the expansion process, under the restriction of the limiting guide shell 221 , the guide plate 224 is pushed to move in the limiting guide shell 221 .

[0042] After the temperature drops, the filling material 223 contracts and returns to its original position under the constraint of the elastic force of the elastic bag 222 itself, and pushes the guide plate 224 to move in the limiting guide shell 221 during the expansion process under the restriction of the limiting guide shell 221.

[0043] It should be noted that one end of the elastic bag 222 is fixedly connected to the inside of the limiting guide shell 221 , and the other end thereof is slidably connected to the limiting guide shell 221 .

[0044] like Figure 8 and 9 As shown, when the elastic bladder 222 is fully contracted, the holes on the orifice plate b232 do not overlap with the holes on the orifice plate a231, and when the elastic bladder 222 is fully expanded, the holes on the orifice plate b232 completely overlap with the holes on the orifice plate a231.

[0045] like Figure 8 and 9 As shown, it also includes an airflow driving component 3, including at least one airflow driver 31 arranged between two movable valve plate components 23, and a solar power supply component 32 arranged on the beam 111 of the side frame 11 away from the side of the building, wherein the solar power supply component 32 is electrically connected to the airflow driver 31.

[0046] The airflow driver 31 is a commercially available fan, which is driven by a solar power supply component 32 .

[0047] In one embodiment, the prefabricated curtain wall is not provided with an airflow driving component 3. When the temperature rises, the filling material 223 in the elastic bag 222 expands due to heat and pushes the orifice plate b232 through the connecting plate 225 to open the unpowered valve box 2. After all the unpowered valve boxes 2 are opened, the airflow channel 121 inside the prefabricated curtain wall remains connected. After the air inside is heated, the hot air floats up and drives the cold air below to enter the middle frame 12, thereby achieving the effect of cooling the prefabricated curtain wall and reducing the energy consumption of the building when the temperature is high.

[0048] In another embodiment, the prefabricated curtain wall is provided with an airflow driving component 3, and the solar power supply component 32 drives the airflow driver 31 to operate continuously. When the temperature rises, the filler 223 in the elastic bag 222 expands due to heat and pushes the orifice plate b232 through the connecting plate 225 to open the unpowered valve box 2. After all the unpowered valve boxes 2 are opened, the airflow channel 121 inside the prefabricated curtain wall remains connected. At the same time, the airflow driver 31 serves to increase the internal air circulation efficiency. After the internal air is heated, the hot air floats up and drives the cold air at the bottom to enter the middle frame 12, thereby achieving the effect of cooling the prefabricated curtain wall and reducing the energy consumption of the building when the temperature is high.

[0049] When the unpowered valve box 2 in some prefabricated curtain walls is opened and some are closed, due to the flow of hot air inside and the transfer of temperature, the partially closed unpowered valve box 2 is heated by the air in other prefabricated curtain walls, and finally a full opening effect is achieved.

[0050] It should be noted that the specific models and specifications of the airflow driver 31 and the solar power supply component 32 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0051] The power supply and principle of the air flow driver 31 and the solar power supply component 32 are clear to those skilled in the art and will not be described in detail here.

[0052] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
