Description

Technical Field

[0001] This invention relates to the field of low-carbon building technology, and in particular to a prefabricated low-carbon building curtain wall installation structure and method. Background Technology

[0002] Low-carbon buildings refer to buildings that reduce the use of fossil fuels, improve energy efficiency, and reduce carbon dioxide emissions throughout their entire lifecycle, from the manufacturing of building materials and equipment to construction and use. Low-carbon buildings have gradually become a mainstream trend in the international construction industry. A fact often overlooked is that buildings account for almost 50% of total carbon dioxide emissions, a proportion far higher than that of the transportation and industrial sectors.

[0003] People are increasingly aware that the surge in carbon dioxide emissions will lead to global warming, which poses a serious threat to the survival and development of all humanity. In fact, in cities, 60% of carbon emissions come from the building's maintenance function itself, while transportation vehicles account for only 30%.

[0004] The real estate industry, in particular, is a major energy consumer. Statistics show that approximately 0.8 tons of carbon are released for every square meter of housing built in China. Furthermore, energy is used for building heating, air conditioning, ventilation, and lighting during real estate development, resulting in significant carbon emissions.

[0005] Wall energy-saving technology: There are three types of composite wall technology: internal insulation layer, external insulation layer, and sandwich insulation layer, as well as curtain walls. In my country, sandwich insulation is more commonly used; in European countries, external foamed polystyrene board is more commonly used. In Germany, external insulation accounts for 80% of the total number of buildings, and 70% of them use foamed polystyrene board.

[0006] Low-carbon buildings can reduce the use of fossil fuels, improve energy efficiency, and reduce carbon dioxide emissions throughout their entire life cycle. The thermal insulation performance provided by the curtain wall system is the fundamental prerequisite for ensuring low-carbon buildings. Curtain walls are lightweight walls with decorative effects commonly used in modern large and high-rise buildings. They are the exterior cladding of buildings and do not bear weight. The installation of curtain walls requires fixing the main installation body to the exterior wall of the building, and then installing each curtain wall unit through the main installation body to achieve the overall installation of the curtain wall.

[0007] In existing technologies, although most curtain wall installation bodies are modularly designed, each module is in an unfolded state. This unfolded state not only occupies a significant amount of space during transportation but also requires constant adjustments by installers during installation to accommodate the fixed positions of each module. For example, Chinese invention patent CN111705983B discloses a building curtain wall installation structure, which includes a curtain wall body and a frame for installing the curtain wall body. The frame includes horizontal keels arranged horizontally and vertical keels arranged vertically, with the ends of the horizontal keels and... The vertical keel is fixedly connected, and a top block is fixedly installed at the center of the back of the curtain wall body. Fixed rods are fixedly installed at the four corners of the back of the curtain wall body. The surface of the horizontal keel has a first insertion hole that engages with the top block, and the vertical keel has a second insertion hole that engages with the fixed rod. A sliding rod is slidably connected between the first insertion hole and the second insertion hole. The side wall of the fixed rod has a locking hole that engages with the sliding rod. When the top block is inserted into the first insertion hole, the sliding rod slides into the second insertion hole and is inserted into the locking hole. The top block is provided with a locking component for fixing the top block and the horizontal keel.

[0008] In the above technical solution, the keel frame is a fixed structure and occupies a large area. When installing the keel frame, adjusting the position between each keel frame requires workers to perform relatively tedious adjustment work. At the same time, this type of keel frame occupies a lot of space during transportation, which increases transportation costs. Summary of the Invention

[0009] The purpose of this invention is to provide a prefabricated low-carbon building curtain wall installation structure and method to solve the technical problems of inconvenience in transportation and installation caused by the inability to fold the main body of the installation in the prior art.

[0031] Furthermore, the pneumatic assembly includes:

[0032] The tube body is disposed on the inner side wall of the crossbeam near the fixed seat;

[0033] The first piston is slidably disposed on the inner side wall of the tube. A transmission rod is provided on the side wall of the first piston, and the transmission rod passes through the inner side wall of the rectangular hole.

[0034] A sealing seat is disposed inside a crossbeam. A circular groove is provided on one side of the sealing seat, and a second piston is slidably disposed in the circular groove. The second piston and the connecting claw form a transmission engagement.

[0035] Furthermore, it also includes:

[0036] A U-shaped tube, one end of which is disposed on the inner sidewall of a circular groove, and the other end of which penetrates the sidewall of the sealing seat;

[0037] A connecting pipe is provided on the inner wall of the crossbeam and is located between the pipe body and the sealing seat. The connecting pipe is connected to the rubber airbag.

[0038] Furthermore, the fastening assembly also includes:

[0039] The slider is slidably disposed inside the crossbeam. The top and bottom of the slider's sidewall are both arc-shaped structures. A rod is provided on one side of the slider, and the rod and the second piston are fixed.

[0040] A spherical groove is formed on the side wall of the slider;

[0041] The ball head is slidably disposed in the spherical groove, and the connecting claw is fixed to the ball head.

[0042] Furthermore, it also includes:

[0043] A hook is provided at the end of the slider.

[0044] Furthermore, the connection component includes:

[0045] Two support plates are provided on the side wall of the mounting base, and two connecting grooves are provided on each of the two support plates.

[0046] Four connecting blocks are provided, with each of the four connecting blocks arranged in pairs on the sidewalls of the two crossbeams, and the connecting blocks and connecting grooves are rotatably connected.

[0047] Another aspect of the present invention provides an installation method for a prefabricated low-carbon building curtain wall, the installation method comprising the following steps:

[0048] S1: During transportation, ensure that both crossbeams are perpendicular to the mounting base, i.e., the crossbeams are in a vertical state. Place the trapezoidal prism inside the circular groove, pull the connecting shaft to extend it out of the support, and fix the connecting shaft with a rubber sleeve to increase the height of the connecting plate. Rotate the connecting plate on the connecting shaft to face the crossbeam so that the connecting plate contacts the side wall of the crossbeam, and the contact position is above the rectangular hole. Lock the vertical crossbeam with the connecting plate to prevent the crossbeam from rotating around the support plate. Then, fasten the two crossbeams with fasteners such as cable ties to further prevent the crossbeams from unfolding during transportation. This allows the device to be transported in a folded state, reducing the footprint and facilitating transportation.

[0049] S2: Fix the structure to the building exterior wall with the mounting base using expansion bolts and other fasteners. Remove the fasteners that tightly bind the two crossbeams. Then rotate the connecting plate so that the connecting plate is parallel to the rectangular hole. Push the connecting shaft into the circular groove. At this time, under the action of the connecting block and the connecting groove, rotate the crossbeam. The connecting plate, support, etc. pass through the rectangular hole on the crossbeam until the crossbeam is rotated to a horizontal state.

[0050] S3: Rotate the connecting plate again to make the trapezoidal prism, wedge, and triangular groove fit together. At this time, the connecting plate is perpendicular to the rectangular hole, the L-shaped plate is directly above the sliding seat, and the trapezoidal prism and wedge part enters the triangular groove.

[0051] S4: Fix another mounting structure to the exterior wall of the building, and then engage the adjacent hooks of the two mounting structures with each other;

[0052] S5: Use a tool to strike the connecting plate, so that the trapezoidal prism and the wedge block are fully inserted into the triangular groove. The wedge block fixes the trapezoidal prism and the triangular groove. At this time, the connecting plate restricts the horizontal beam from rotating.

[0053] S6: During the descent of the connecting plate, the L-shaped plate on the connecting plate contacts the sliding seat and pushes the sliding seat down. Under the action of the rubber block, the first connecting rod and the second connecting rod form a certain angle. Then, during the descent of the sliding seat, the first connecting rod drives the second connecting rod to rotate around the fixed seat. The second connecting rod contacts the transmission rod and drives the transmission rod to move during the rotation of the second connecting rod, which in turn drives the first piston to move, causing the air pressure in the crossbeam between the tube body and the sealing seat to rise.

[0054] S7: After the air pressure in the horizontal beam between the tube and the sealing seat rises, the rubber airbag expands through the connecting pipe, which facilitates the support of the curtain wall units during the installation process. The rubber airbag is squeezed by each curtain wall unit, which fills the gap between the curtain wall units and prevents a large amount of glue from leaking out when the glue is injected between the curtain wall units. This facilitates the glue injection work. At the same time as the air pressure in the horizontal beam between the tube and the sealing seat rises, the air pressure inside the circular groove rises through the U-shaped tube, which pushes the second piston to move and drives the slider to move through the rod.

[0055] S8: The slider moves, but the connecting claw in the connection hole cannot move horizontally, so the ball head slides along the spherical groove. Through the arc structure of the slider, the connecting claw slides along the connection hole, realizing the unfolding of the connecting claw. The curtain wall unit is fixed by the connecting claw. After the curtain wall unit is fixed, the glue injection work is carried out to complete the installation of the curtain wall unit.

[0056] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0057] (1) The present invention uses a rubber sleeve to fix the connecting shaft and the circular groove, thereby adjusting the height of the connecting shaft and changing the height of the connecting plate. With the rotation of the connecting plate, when the end of the connecting plate and the side of the crossbeam come into contact, the vertical crossbeam is restricted, so that the main body of the installation can be folded, reducing the footprint and facilitating the installation and transportation work. Reducing the number of transportations also fully reflects the concept of low carbon emissions in the construction process of low carbon buildings, and to a certain extent highlights the environmental protection performance of this installation structure.

[0058] (2) The present invention changes the height of the connecting plate by sliding up and down between the connecting shaft and the circular groove, so that the connecting plate can pass through the rectangular hole during the rotation of the crossbeam, thereby ensuring the normal unfolding of the crossbeam. The installation body is spliced ​​and connected by hooks to realize the installation of this installation structure. The hooks determine the various installation positions of the main body of the installation structure, ensuring the rapid progress of the installation work. The efficient installation process can effectively reduce the working time of lifting equipment, etc., thereby reducing the carbon emissions in the entire installation process.

[0059] (3) The present invention, through the pneumatic components, rubber airbags and fastening components, enables the rubber airbags and the connecting claws to be automatically deployed during the fixing of the crossbeam. The rubber airbags provide initial support for the curtain wall units. After being squeezed by the curtain wall units, the rubber airbags can fill the gaps between the curtain wall units, which facilitates the glue injection work. The automatic deployment of the connecting claws facilitates the fixing of the curtain wall units and the fixing of the main body of the installation structure. Attached Figure Description

[0078] The following is combined with Figures 1 to 10 As shown, one aspect of the present invention provides a prefabricated low-carbon building curtain wall installation structure, comprising:

[0079] Mounting base 101, a connecting component is provided on one side of the mounting base 101;

[0080] Two horizontal beams 201 are symmetrically arranged and rotatably connected to the connecting components. Each horizontal beam 201 has a rectangular hole on one side and a connecting hole on each side wall of the end of the two horizontal beams 201 away from the mounting base 101. A fastening component is slidably arranged in each connecting hole and is used to fix the curtain wall unit.

[0081] Two fixing components are provided on the side wall of the mounting base 101, and the two fixing components are used to restrict the rotation of the two crossbeams 201 respectively.

[0082] The fixing component can be used to restrict the rotation of the vertical beam 201 or the horizontal beam 201. The fixing component can be placed in two stations. When the fixing component is in station one, the trapezoidal prism 311 is placed inside the circular groove 308, the connecting shaft 309 is pulled to extend the connecting shaft 309 out of the support 301, and the connecting shaft 309 is fixed by the rubber sleeve 310 to increase the height of the connecting plate 302. The connecting plate 302 on the connecting shaft 309 is rotated to face the beam 201, so that the connecting plate 302 and the side wall of the beam 201 are in contact, and the contact position is above the rectangular hole. The vertical beam 201 is locked by the connecting plate 302. When the fixing component is in station two, the trapezoidal prism 311 and the wedge 312 are fully inserted into the triangular groove 313. The trapezoidal prism 311 and the triangular groove 313 are fixed by the wedge 312. The horizontal beam 201 is restricted from rotating by the connecting plate 302 at this time.

[0083] Rubber airbag 202 is installed on one side of the crossbeam 201 and is used to support the curtain wall unit.

[0084] Fastening components include:

[0085] The connecting claw 203 is used to fix the curtain wall unit, and the connecting claw 203 is slidably set in the connection hole;

[0086] The pneumatic component is installed inside the crossbeam 201. The pneumatic component, the connecting claw 203 and the fixing component form a transmission connection. The pneumatic component is connected to the rubber airbag 202.

[0087] During the process of fixing the crossbeam 201 in a fixed state by the fixing component, the pneumatic component is driven to work, which in turn causes the rubber airbag 202 to expand and the connecting claw 203 to unfold, which facilitates the fixing of the main body and the installation of the curtain wall unit. Through the two workings of the fixing component, the crossbeam 201 in different states is restricted, ensuring the stability of the crossbeam 201 in each state.

[0088] Furthermore, the fixing components include:

[0089] Support 301 is mounted on support plate 102. A circular groove 308 is provided at the top of support 301 and a triangular groove 313 is provided at the bottom of circular groove 308. The triangular groove 313 is an equilateral triangle.

[0090] A connecting shaft 309 is adapted to a circular groove 308, and a rubber sleeve 310 is fitted on the side wall of the connecting shaft 309 near the support 301.

[0091] Trapezoidal prism 311 is provided at the end of connecting shaft 309, and trapezoidal prism 311 is adapted to triangular groove 313;

[0092] Wedge 312 is set on the side wall of trapezoidal prism 311. Wedge 312 has a frustum structure and a triangular cross-section. The end of wedge 312 is adapted to the triangular groove 313.

[0093] In this embodiment, the wedge 312 can be made of soft wood such as paulownia wood. After the trapezoidal prism 311 and the wedge 312 are embedded in the triangular groove 313, the wedge 312 of the frustum structure deforms, ensuring the stability between the trapezoidal prism 311 and the support 301, thereby ensuring that the crossbeam 201 will not rotate after unfolding.

[0094] Furthermore, it also includes:

[0095] Connecting plate 302 is disposed at the end of connecting shaft 309;

[0096] L-shaped plate 303 is installed on the side wall of connecting plate 302;

[0097] Sliding seat 304 is slidably disposed on the side wall of support 301;

[0098] The fixed seat 307 is fixedly installed on the side wall of the support 301, and the fixed seat 307 is located directly below the sliding seat 304;

[0099] The first link 305 and the second link 306 are rotatably mounted on the side wall of the sliding seat 304, and the second link 306 is rotatably mounted on the fixed seat 307. The ends of the first link 305 and the second link 306 are rotatably connected.

[0100] Rubber block 314 is installed on the side wall of the second connecting rod 306.

[0101] During the process of embedding the trapezoidal prism 311 and wedge 312 into the triangular groove 313, the connecting plate 302 descends, and the sliding seat 304 descends through the L-shaped plate 303, which in turn drives the transmission rod 504 to move through the first connecting rod 305, the second connecting rod 306, and the inclined structure of the cooperating transmission rod 504.

[0102] Furthermore, the pneumatic components include:

[0103] Pipe body 502 is installed on the inner wall of the crossbeam 201 near the fixed seat 307;

[0104] The first piston 503 is slidably disposed on the inner wall of the tube 502. A transmission rod 504 is provided on the side wall of the first piston 503, and the transmission rod 504 passes through the inner wall of the rectangular hole. The end of the transmission rod 504 away from the first piston 503 is a beveled structure.

[0105] A sealing seat 501 is disposed inside the crossbeam 201. A circular groove is provided on one side of the sealing seat 501. A second piston 505 is slidably disposed in the circular groove. The second piston 505 and the connecting claw 203 form a transmission engagement.

[0106] Also includes:

[0107] U-shaped tube 506, one end of which is set on the inner side wall of the circular groove, and the other end of which penetrates the side wall of the sealing seat 501;

[0108] The connecting pipe 205 is installed on the inner wall of the crossbeam 201 and is located between the pipe body 502 and the sealing seat 501. The connecting pipe 205 is connected to the rubber airbag 202.

[0109] During the movement of the transmission rod 504, the first piston 503 is driven to move, which causes the air pressure in the crossbeam 201 between the tube body 502 and the sealing seat 501 to rise, thereby causing the second piston 505 to move and the rubber airbag 202 to inflate.

[0110] Furthermore, the fastening components also include:

[0111] The slider 402 is slidably disposed inside the crossbeam 201. The top and bottom of the side wall of the slider 402 are both arc structures. A rod 401 is provided on one side of the slider 402, and the rod 401 and the second piston 505 are fixed.

[0112] A spherical groove 403 is formed on the side wall of the slider 402;

[0113] The ball head 404 is slidably disposed in the spherical groove 403, and the connecting claw 203 and the ball head 404 are fixed.

[0114] During the movement of the second piston 505, the slider 402 is moved by the rod 401. However, the connecting claw 203 in the connecting hole cannot move horizontally, so the ball head 404 slides along the spherical groove 403. Through the arc structure of the slider 402, the connecting claw 203 slides along the connecting hole, realizing the unfolding of the connecting claw 203. By fixing each curtain wall unit with the connecting claw 203, the installation and disassembly of each curtain wall unit can be realized, which facilitates the subsequent recycling of the curtain wall unit.

[0115] Furthermore, it also includes:

[0116] Hook 6 is located at the end of slider 402.

[0117] Furthermore, the connection components include:

[0118] Two support plates 102 are provided on the side wall of the mounting base 101, and two connecting grooves 103 are provided on each of the two support plates 102.

[0119] Four connecting blocks 204 are arranged in pairs on the side walls of the two crossbeams 201, and the connecting blocks 204 are rotatably connected to the connecting grooves 103.

[0120] Another aspect of the present invention provides an installation method for a prefabricated low-carbon building curtain wall, comprising the following steps:

[0121] S1: During transportation, ensure that both crossbeams 201 are perpendicular to the mounting base 101, i.e., the crossbeams 201 are in a vertical state. Place the trapezoidal prism 311 inside the circular groove 308, pull the connecting shaft 309 so that the connecting shaft 309 extends out of the support 301, and fix the connecting shaft 309 with the rubber sleeve 310 to increase the height of the connecting plate 302. Rotate the connecting plate 302 on the connecting shaft 309 to face the crossbeam 201 so that the connecting plate 302 and the side wall of the crossbeam 201 are in contact, and the contact position is above the rectangular hole. Lock the vertical crossbeam 201 with the connecting plate 302 to prevent the crossbeam 201 from rotating around the support plate 102. Then, fasten the two crossbeams 201 with fasteners such as cable ties to further prevent the crossbeams 201 from unfolding during transportation, realize the transportation of this device in a folded state, reduce the footprint, and facilitate the transportation work.

[0122] S2: Fix the structure to the building exterior wall with the mounting base 101 using fasteners such as expansion bolts. Remove the fasteners that tightly bind the two crossbeams 201. Then rotate the connecting plate 302 so that the connecting plate 302 is parallel to the rectangular hole. Push the connecting shaft 309 into the circular groove 308. At this time, under the action of the connecting block 204 and the connecting groove 103, the crossbeam 201 is rotated. The connecting plate 302, the support 301, etc. pass through the rectangular hole on the crossbeam 201 until the crossbeam 201 is rotated to a horizontal state.

[0123] S3: Rotate the connecting plate 302 again so that the trapezoidal prism 311, wedge 312 and triangular groove 313 are in the matching state. At this time, the connecting plate 302 is perpendicular to the rectangular hole, the L-shaped plate 303 is directly above the sliding seat 304, and the trapezoidal prism 311 and wedge 312 are partially inserted into the triangular groove 313.

[0124] S4: Fix another mounting structure to the exterior wall of the building, and then engage the adjacent hooks 6 of the two mounting structures with each other;

[0125] S5: By striking the connecting plate 302 with a tool, the trapezoidal prism 311 and the wedge 312 are completely inserted into the triangular groove 313. The wedge 312 fixes the trapezoidal prism 311 and the triangular groove 313. At this time, the connecting plate 302 restricts the horizontal beam 201 from rotating.

[0126] S6: During the descent of the connecting plate 302, the L-shaped plate 303 on the connecting plate 302 contacts the sliding seat 304 and pushes the sliding seat 304 down. Under the action of the rubber block 314, the first connecting rod 305 and the second connecting rod 306 form a certain angle. Then, during the descent of the sliding seat 304, the first connecting rod 305 drives the second connecting rod 306 to rotate around the fixed seat 307. The second connecting rod 306 contacts the transmission rod 504 and drives the transmission rod 504 to move during the rotation of the second connecting rod 306, which in turn drives the first piston 503 to move, causing the air pressure in the crossbeam 201 between the tube body 502 and the sealing seat 501 to rise.

[0127] S7: After the air pressure in the crossbeam 201 between the tube body 502 and the sealing seat 501 rises, the rubber airbag 202 expands through the connecting pipe 205, which facilitates the support of the curtain wall units during the installation of the curtain wall. The rubber airbag 202 is filled by the compression of each curtain wall unit, which prevents a large amount of glue from leaking when the curtain wall units are injected with glue, thus facilitating the glue injection work. At the same time as the air pressure in the crossbeam 201 between the tube body 502 and the sealing seat 501 rises, the air pressure inside the circular groove rises through the U-shaped tube 506, which pushes the second piston 505 to move, and drives the slider 402 to move through the rod 401.

[0128] S8: When slider 402 moves, the connecting claw 203 in the connecting hole cannot move horizontally, causing ball head 404 to slide along spherical groove 403. Through the arc structure of slider 402, the connecting claw 203 slides along the connecting hole, realizing the unfolding of connecting claw 203. The curtain wall unit is fixed by connecting claw 203. After the curtain wall unit is fixed, the glue injection work is carried out to complete the installation of the curtain wall unit.

[0129] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.

7. A curtain wall installation structure according to any one of claims 1-6, characterized in that: The installation method includes the following steps: S1: During transportation, ensure that both crossbeams (201) are perpendicular to the mounting base (101), that is, the crossbeams (201) are in a vertical state. Place the trapezoidal prism (311) inside the circular groove (308), pull the connecting shaft (309) so that the connecting shaft (309) extends out of the support (301), and fix the connecting shaft (309) with the rubber sleeve (310) to increase the height of the connecting plate (302) and make the connecting plate (302) on the connecting shaft (309) more stable. Rotate to face the crossbeam (201) so that the connecting plate (302) and the side wall of the crossbeam (201) come into contact and the contact position is above the rectangular hole. The connecting plate (302) locks the vertical crossbeam (201) to prevent the crossbeam (201) from rotating around the support plate (102). Then, the two crossbeams (201) are tied with cable ties to further prevent the crossbeams (201) from unfolding during transportation. This realizes the transportation of the device in a folded state, reduces the footprint, and facilitates the transportation work. S2: Fix the structure to the building exterior wall with the mounting base (101) by expansion bolts, remove the fasteners that tightly bind the two crossbeams (201), then rotate the connecting plate (302) so that the connecting plate (302) is parallel to the rectangular hole, push the connecting shaft (309) into the circular groove (308), at this time, under the action of the connecting block (204) and the connecting groove (103), rotate the crossbeam (201), and the connecting plate (302) and the support (301) pass through the rectangular hole on the crossbeam (201) until the crossbeam (201) rotates to a horizontal state; S3: Rotate the connecting plate (302) again to make the trapezoidal prism (311), wedge (312) and triangular groove (313) fit together. At this time, the connecting plate (302) is perpendicular to the rectangular hole, the L-shaped plate (303) is directly above the sliding seat (304), and the trapezoidal prism (311) and wedge (312) are partially inserted into the triangular groove (313). S4: Fix another mounting structure to the exterior wall of the building, and then engage the adjacent hooks (6) of the two mounting structures with each other; S5: By striking the connecting plate (302) with a tool, the trapezoidal prism (311) and the wedge (312) are completely inserted into the triangular groove (313). The trapezoidal prism (311) and the triangular groove (313) are fixed by the wedge (312). The horizontal beam (201) is restricted from rotating by the connecting plate (302) at this time. S6: During the descent of the connecting plate (302), the L-shaped plate (303) on the connecting plate (302) contacts the sliding seat (304) and pushes the sliding seat (304) to descend. Under the action of the rubber block (314), the first connecting rod (305) and the second connecting rod (306) form a certain angle. Then, during the descent of the sliding seat (304), the first connecting rod (305) drives the second connecting rod (306) to rotate around the fixed seat (307). The second connecting rod (306) contacts the transmission rod (504) and drives the transmission rod (504) to move during the rotation of the second connecting rod (306), which in turn drives the first piston (503) to move, causing the air pressure in the crossbeam (201) between the tube body (502) and the sealing seat (501) to rise. S7: After the air pressure in the crossbeam (201) between the tube body (502) and the sealing seat (501) rises, the rubber airbag (202) expands through the connecting pipe (205), which facilitates the support of the curtain wall units during the installation of the curtain wall. Through the compression of the rubber airbag (202) by each curtain wall unit, the rubber airbag (202) fills the gap between the curtain wall units, avoiding a large amount of glue leakage when the glue is injected between the curtain wall units later, which facilitates the glue injection work. At the same time as the air pressure in the crossbeam (201) between the tube body (502) and the sealing seat (501) rises, the air pressure inside the circular groove rises through the U-shaped tube (506), which pushes the second piston (505) to move, and drives the slider (402) to move through the rod body (401). S8: The slider (402) moves, but the connecting claw (203) in the connecting hole cannot move horizontally, so the ball head (404) slides along the spherical groove (403). Through the arc structure of the slider (402), the connecting claw (203) slides along the connecting hole, realizing the unfolding of the connecting claw (203). The curtain wall unit is fixed by the connecting claw (203). After the curtain wall unit is fixed, the glue injection work is carried out to complete the installation of the curtain wall unit.
