Description

Technical Field

[0001] The invention relates to the technical field of curtain walls, and in particular to an embedded unitized curtain wall structure and an installation method thereof. Background Art

[0002] The unitized curtain wall is a curtain wall system formed by multiple adjacent unit components that are docked and installed on the periphery of the building. The unit components consist of a frame and panels installed on it. They are assembled in the factory and then transported to the construction site for docking and installation.

[0003] In the related art, after the unitized curtain wall is installed on the main body of the building, it is necessary to inject glue into the gaps between the unitized curtain walls to seal the gaps between the unitized curtain walls, prevent water from penetrating into the interior of the building from the gaps between the unitized curtain walls, and improve the waterproof performance of the curtain wall. However, the injection of glue is done manually, and the glue is injected into the gap from the opening of the gap between the unitized curtain walls. However, the opening of the gap is small and the gap is long, which easily leads to leakage of glue or unqualified injection, resulting in leakage.

[0004] With respect to the above-mentioned related technologies, the applicant believes that the following defects exist: in the related technologies, after installation, the unitized curtain wall is prone to leakage due to glue leakage or unqualified glue injection. Summary of the invention

[0005] In order to reduce leakage accidents after the installation of a unitized curtain wall, the present application provides an embedded unitized curtain wall structure and an installation method thereof.

[0006] On the one hand, the embedded unitized curtain wall structure provided in the present application adopts the following technical solution:

[0007] An embedded unitized curtain wall structure comprises a first curtain wall unit, a second curtain wall unit and a connecting unit, wherein the first curtain wall unit and the second curtain wall unit are both fixedly connected to a building main body via the connecting unit, the first curtain wall unit and the second curtain wall unit are arranged alternately, and the second curtain wall unit is embedded in a space surrounded by the adjacent first curtain wall unit; first sealing strips are respectively arranged around the first curtain wall unit, and second sealing strips are respectively arranged around the second curtain wall unit, the second sealing strips can press the first sealing strips, the first sealing strips are adsorbed with A glue, and the second sealing strips are adsorbed with B glue, and the A glue and the B glue are mixed to form AB glue.

[0008] By adopting the above technical solution, after the adjacent first curtain wall unit and the second curtain wall unit are installed, glue A and glue B come into contact and mix to form AB glue, which fills the gap between the first curtain wall unit and the second curtain wall unit. After coagulation, the gap between the first curtain wall unit and the second curtain wall unit is sealed, realizing the anti-seepage function. This application uses glue A and glue B that can be mixed into AB glue. Since glue A and glue B do not solidify when they exist alone and become sticky and solidify after mixing, glue A and glue B can be pre-adsorbed on the first curtain wall unit and the second curtain wall unit. Glue A and glue B will mix to form AB glue only after the first curtain wall unit and the second curtain wall unit are installed. Therefore, this application does not require post-installation glue injection, and the AB glue formed after installation fills the gap between the first curtain wall unit and the second curtain wall unit, improving the sealing performance of the gap between the first curtain wall unit and the second curtain wall unit, thereby reducing the leakage accidents of the curtain wall structure; at the same time, the AB glue fixedly connects the first curtain wall unit and the second curtain wall unit, making the entire curtain wall form a whole and improving the firmness of the entire curtain wall.

[0009] Preferably, a first cavity is provided in the first sealing strip, a first glue outlet hole is provided on the side wall of the first cavity, glue A is arranged in the first cavity, a second cavity is provided in the second sealing strip, a second glue outlet hole is provided on the side wall of the second cavity, glue B is arranged in the second cavity, and when the first sealing strip is subjected to a squeezing force greater than a set value, glue A flows out from the first glue outlet hole, and when the second sealing strip is subjected to a squeezing force greater than a set value, glue B flows out from the second glue outlet hole.

[0010] By adopting the above technical solution, arranging glue A in the first cavity and glue B in the second cavity is convenient for storage, reducing the situation where glue A and glue B are contaminated by dust during the handling of the first curtain wall unit and the second curtain wall unit; at the same time, it can reduce the evaporation of glue A and glue B during transportation and reduce the situation where glue A and glue B are mixed before the installation of the first curtain wall unit and the second curtain wall unit.

[0011] Preferably, a first pressing plate is provided on the circumference of the first curtain wall unit, the first pressing plate is arranged on the side of the first sealing strip facing the building body, a second pressing plate is provided on the circumference of the second curtain wall unit, and the second pressing plate is arranged on the side of the second sealing strip facing away from the building body.

[0012] By adopting the above technical solution, during installation, the first extrusion plate and the second extrusion plate squeeze the first sealing strip and the second sealing strip in the middle, extrude glue A from the first sealing strip, and extrude glue B from the second sealing strip. The extruded glue A and glue B fill the gap between the first curtain wall unit and the second curtain wall unit and are mixed. After solidification, the first extrusion plate, the second extrusion plate, the first sealing strip and the second sealing strip are connected into an integral structure to form a seal.

[0013] Preferably, the connection unit includes a horizontal movement support plate and a vertical movement support plate. The vertical movement support plate is provided with a vertical long hole, and a vertical movement screw is fixed on the horizontal movement support plate. The vertical movement screw passes through the vertical long hole and is fixedly connected to the vertical movement support plate through a nut; the horizontal movement support plate is provided with a horizontal long hole, and the horizontal long hole avoids the vertical movement support plate. The horizontal movement support plate is installed on the building main body through an expansion bolt, and the expansion bolt passes through the vertical long hole and is fixedly connected to the horizontal movement support plate through a nut; a support plate is connected to the vertical movement support plate, and both the first curtain wall unit and the second curtain wall unit are fixedly connected to the support plate.

[0014] By adopting the above technical solution, the horizontal movement support plate can achieve horizontal position adjustment through the cooperation of the horizontal long hole and the expansion bolt, so as to adjust the horizontal positions of the vertical movement support plate and the support plate. The vertical movement support plate realizes vertical position adjustment through the cooperation of the vertical long hole and the vertical movement screw, so as to adjust the vertical position of the support plate, realizing the horizontal and vertical adjustment of the installation positions of the first curtain wall unit and the second curtain wall unit, and improving the installation accuracy.

[0015] Preferably, a tensioning screw is fixed on the vertical movement support plate. The tensioning screw is arranged above the support plate, and the tensioning screw is connected to the second curtain wall unit through a nut.

[0016] By adopting the above technical solution, since a horizontal force is required for the first sealing strip and the second sealing strip to press against each other, it is not convenient for the operator to apply a horizontal thrust to the second curtain wall unit during high-altitude installation. When the second curtain wall unit is installed on the tensioning screw through a nut, the nut tightens and pulls the second curtain wall unit towards the building main body, causing the second curtain wall unit to press against the first curtain wall unit towards the building main body, and the second sealing strip presses against the first sealing strip, facilitating the contact and mixing of glue A and glue B to form AB glue, which is convenient for installation.

[0017] Preferably, the adjacent sides of the first curtain wall unit and the second curtain wall unit that are close to each other are connected to the same connection unit. The first curtain wall unit is provided with a first connecting plate, and the second curtain wall unit is provided with a second connecting plate. The first connecting plate is fixedly connected to the support plate through a bolt, and the second connecting plate is fixedly connected to the support plate through a bolt and is connected to the tensioning screw through a nut.

[0018] By adopting the above technical solution, the pressing degree of the first sealing strip and the second sealing strip is determined by the positions of the connecting support plates of the first curtain wall unit and the second curtain wall unit, and the positions of the connecting support plates of the first curtain wall unit and the second curtain wall unit have been determined when designing the support plates, which can keep the first sealing strip and the second sealing strip pressed against each other and reduce the occurrence of gaps between the first sealing strip and the second sealing strip.

[0019] On the other hand, an installation method for an embedded unitized curtain wall structure provided by the present application adopts the following technical solution:

[0020] An installation method for an embedded unitized curtain wall structure includes the following steps:

[0021] Installation of connecting units: Measure and set out the lines on site according to the drawings to determine the specific positions where the first curtain wall unit and the second curtain wall unit are to be installed on the building main body; then drill holes and install the connecting units on the building main body;

[0022] Installation of the first curtain wall unit: Install the first curtain wall unit vertically and horizontally in a staggered manner on the connecting units, and then adjust the position of the first curtain wall unit according to the designed position so that the installation error of each first curtain wall unit is within the allowable error range;

[0023] Installation of the second curtain wall unit: Embed the second curtain wall unit one by one into the space surrounded by the first curtain wall unit, and press the embedded second curtain wall unit towards the building main body so that the first sealing strip and the second sealing strip are pressed against each other, and then fix the second curtain wall unit to the connecting units;

[0024] Curtain wall cleaning: After the installation of both the first curtain wall unit and the second curtain wall unit is completed, clean the curtain wall and check for leakage during the cleaning process; if there is leakage, apply a dissolving agent around the second curtain wall unit adjacent to the leakage point to dissolve the AB glue, then remove the second curtain wall unit, clean the AB glue around the removed second curtain wall unit, and clean the AB glue on the first curtain wall unit in contact with the removed second curtain wall unit. Then reinstall the removed second curtain wall unit in place and inject glue around the second curtain wall unit for sealing.

[0025] By adopting the above technical solution, the installation error is adjusted when installing the first curtain wall unit. Therefore, there is no need to adjust the installation error when installing the second curtain wall unit, and the second curtain wall unit is embedded in the space surrounded by the first curtain wall unit. When installing the second curtain wall unit, it can be pressed tightly towards the building main body, meeting the condition that the gap between the first curtain wall unit and the second curtain wall unit is sealed with glue. Therefore, the first curtain wall unit and the second curtain wall unit can be fixed to each other by filling the gap between the first curtain wall unit and the second curtain wall unit with AB glue formed by mixing A glue and B glue; when leakage occurs, only the second curtain wall unit at the leakage point needs to be removed to repair the leakage point, which is convenient for subsequent leak repair operations and reduces the difficulty of later maintenance.

[0026] Preferably, during the installation of the second curtain wall unit, if it is found that glue continuously leaks from the gap between the first curtain wall unit and the second curtain wall unit, use tape to seal the leakage point and then remove the tape after the glue solidifies.

[0027] By adopting the above technical solution, since there is a gap between the first curtain wall unit and the second curtain wall unit, if the gap is large, the AB glue is likely to continuously leak out before coagulation. It only needs to block the leakage point and wait for the AB glue to coagulate.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. Since the second curtain wall unit of the present application is embedded in the space surrounded by the adjacent first curtain wall unit, the first curtain wall unit is installed first and the second curtain wall unit is installed later. After the second curtain wall unit is installed, the second sealing strip can be pressed tightly against the first sealing strip, and A glue and B glue come into contact and mix to form AB glue, filling the gap between the first curtain wall unit and the second curtain wall unit. After coagulation, the gap between the first curtain wall unit and the second curtain wall unit is sealed, realizing the anti-seepage function. The present application uses A glue and B glue that can be mixed into AB glue. Since A glue and B glue do not solidify when they exist alone and become sticky and solidify after mixing, A glue and B glue can be pre-adsorbed on the first curtain wall unit and the second curtain wall unit. Only after the first curtain wall unit and the second curtain wall unit are installed will A glue and B glue mix to form AB glue. Therefore, the present application does not require post-installation injection of glue, and the AB glue formed after installation fills the gap between the first curtain wall unit and the second curtain wall unit, improving the sealing performance of the gap between the first curtain wall unit and the second curtain wall unit, thereby reducing the occurrence of leakage accidents in the curtain wall structure; at the same time, the AB glue fixedly connects the first curtain wall unit and the second curtain wall unit, making the entire curtain wall form an integral whole and improving the firmness of the entire curtain wall;

[0030] 2. During installation, the first extrusion plate and the second extrusion plate squeeze the first sealing strip and the second sealing strip in the middle, extrude A glue out of the first sealing strip, and extrude B glue out of the second sealing strip. The extruded A glue and B glue fill the gap between the first curtain wall unit and the second curtain wall unit and are mixed. After solidification, the first extrusion plate, the second extrusion plate, the first sealing strip and the second sealing strip are connected into an integral structure to form a seal;

[0031] 3. When the second curtain wall unit is installed on the tensioning screw through a nut, when the nut is tightened, the second curtain wall unit is tightened towards the building main body, so that the second curtain wall unit presses the first curtain wall unit towards the building main body, and the second sealing strip presses the first sealing strip, facilitating the contact and mixing of A glue and B glue to form AB glue, which is convenient for installation;

[0032] 4. After the installation of the first curtain wall unit and the second curtain wall unit in this application is completed, there is no need to inject glue into the gap between the first curtain wall unit and the second curtain wall unit, reducing the installation process and improving the installation efficiency; when leakage occurs, only the second curtain wall unit at the leakage location needs to be removed to repair the leakage location, facilitating the later leakage repair operation and reducing the later maintenance difficulty.

[0043] The following will further elaborate on this application in conjunction with the attached Figure 1-8 drawings.

[0044] The embodiment of this application discloses an embedded unitized curtain wall structure and its installation method.

[0045] Referring to Figure 1 , an embedded unitized curtain wall structure includes a first curtain wall unit 1, a second curtain wall unit 2, and a connecting unit 3. Both the first curtain wall unit 1 and the second curtain wall unit 2 are fixedly connected to the building main body through the connecting unit 3. The first curtain wall unit 1 and the second curtain wall unit 2 are arranged alternately at intervals. The second curtain wall unit 2 is embedded in the space surrounded by the adjacent first curtain wall units 1. Except for the first curtain wall unit 1 and the second curtain wall unit 2 at the edge of the building main body, four second curtain walls are installed around each first curtain wall unit 1 in the middle of the building main body, and four first curtain walls are installed around each second curtain wall unit 2 in the middle of the building main body. Referring to Figure 2 and Figure 4, a first seal strip 11 is provided around the first curtain wall unit 1, and a second seal strip 21 is provided around the second curtain wall unit 2. The second seal strip 21 and the first seal strip 11 have the same structure. The second seal strip 21 can press tightly against the first seal strip 11. The first seal strip 11 adsorbs glue A, and the second seal strip 21 adsorbs glue B. Glue A and glue B are mixed to form AB glue. Glue A and glue B do not have stickiness when separated, which is convenient for the transportation and storage of the first curtain wall unit 1 and the second curtain wall unit 2. After the first curtain wall unit 1 and the second curtain wall unit 2 are installed, the AB glue formed by mixing glue A and glue B has good stickiness, which can firmly paste the adjacent first curtain wall unit 1 and the second curtain wall unit 2 and seal the gap between the adjacent first curtain wall unit 1 and the second curtain wall unit 2. The distribution method of the first curtain wall unit 1 and the second curtain wall unit 2 and the design of the second curtain wall unit 2 in an embedded manner provide the basic condition for the second seal strip 21 to press tightly against the first seal strip 11, so that every position of each first seal strip 11 can contact the second seal strip 21, and every position of each second seal strip 21 can also contact the first seal strip 11, so that the gap between each first curtain wall unit 1 and the second curtain wall unit 2 can be filled with AB glue, thereby sealing and waterproofing, and connecting the entire curtain wall into a whole.

[0046] Refer to Figure 2 and Figure 4 , the first curtain wall unit 1 includes a first frame and a glass panel. The first frame is square, and the glass panel is fixed within the first frame; the second curtain wall unit 2 includes a second frame and a grille panel. The second frame is square, and the grille panel is fixed within the second frame. A first extrusion plate 12 is fixedly connected to each of the four side walls of the first frame. The connection points of the four extrusion plates need to be chamfered to avoid interference during installation and prevent the installation from not being in place. The first extrusion plate 12 is located on the side of the first seal strip 11 facing the building body, and the first seal strip 11 is fixedly pasted on the first extrusion plate 12. A second extrusion plate 22 is fixedly connected to each of the four side walls of the second frame. The second extrusion plate 22 is located on the side of the second seal strip 21 facing away from the building body, and the second seal strip 21 is fixedly pasted on the second extrusion plate 22. When the second curtain wall unit 2 is installed, the first extrusion plate 12 and the second extrusion plate 22 squeeze the first seal strip 11 and the second seal strip 21 in the middle, squeeze out glue A from the first seal strip 11, and squeeze out glue B from the second seal strip 21, without the need to use additional tools to squeeze the first seal strip 11 and the second seal strip 21, improving the installation efficiency of the curtain wall. Both the first seal strip 11 and the second seal strip 21 are made of elastic rubber. Refer to Figure 3 and Figure 5A first cavity 111 is provided in the first sealing strip 11, and a plurality of first glue outlet holes 112 are arranged on the side wall of the first cavity 111. Glue A is arranged in the first cavity 111; a second cavity 211 is provided in the second sealing strip 21, and a second glue outlet hole 212 is arranged on the side wall of the second cavity 211. Glue B is arranged in the second cavity 211. Glue A and glue B are easy to store and can be stored for a long time, thereby reducing the probability of glue A and glue B being contaminated by dust.

[0047] The apertures of the first glue outlet hole 112 and the second glue outlet hole 212 are both 20 microns. There are multiple first glue outlet holes 112 and second glue outlet holes 212. The multiple first glue outlet holes 112 are evenly distributed on the first sealing strip 11, and the distance between two adjacent first glue outlet holes 112 is 1 mm. The multiple second glue outlet holes 212 are evenly distributed on the second sealing strip 21, and the distance between two adjacent second glue outlet holes 212 is 1 mm. When the first sealing strip 11 and the second sealing strip 21 are not subjected to pressure, due to factors such as the surface tension and viscous resistance of glue A and glue B, glue A and glue B cannot flow out of the first cavity 111 and the second cavity 211; when the first sealing strip 11 and the second sealing strip 21 are subjected to an extrusion force greater than a set value, part of the side walls of the first sealing strip 11 and the second sealing strip 21 are stretched, so that the first glue outlet hole 112 and the second glue outlet hole 212 are enlarged, and the pressure in the first cavity 111 and the second cavity 211 increases, and glue A flows out from the first glue outlet hole 112, and glue B flows out from the second glue outlet hole 212. The flowing glue A and glue B are mixed outside the first sealing strip 11 and the second sealing strip 21 to form glue AB, which seals the gap between the first curtain wall unit 1 and the second curtain wall unit 2 after solidification.

[0048] Reference Figure 6 and Figure 7, the connecting unit 3 includes a transverse support plate 31 and a vertical support plate 33. Horizontally elongated holes 32 are provided at the upper and lower ends of the transverse support plate 31 respectively. The two horizontally elongated holes 32 are parallel to each other. The transverse support plate 31 is installed on the building main body through expansion bolts. The expansion bolts pass through the vertically elongated holes and are fixedly connected to the transverse support plate 31 through nuts. Loosening the nuts allows the transverse support plate 31 to move left and right. After the transverse support plate 31 moves to the required position, tightening the nuts can fix the transverse support plate 31 to complete the adjustment of the horizontal position of the transverse support plate 31. On the side of the transverse support plate 31 facing away from the building main body, two vertical moving screw rods 34 are fixed. The two vertical moving screw rods 34 are parallel to each other and are in the same vertical plane. The vertical moving screw rods 34 are perpendicular to the transverse support plate 31. The vertical support plate 33 is parallel to the transverse support plate 31. The vertical support plate 33 is arranged on the side of the transverse support facing away from the building main body and is between the two horizontally elongated holes 32. A vertically elongated hole is provided in the middle of the vertical support plate 33. Both vertical moving screw rods 34 pass through the vertically elongated hole and are fixedly connected to the vertical support plate 33 through nuts. Loosen the nuts and move the vertical support plate 33 up and down to the required position, and then tighten the nuts to complete the adjustment of the vertical position of the vertical support plate 33.

[0049] Refer to Figure 6 and Figure 7 , a support plate 35 is connected to the vertical support plate 33. The support plate 35 is perpendicular to the vertical support plate 33 and parallel to the horizontally elongated holes 32. The support plate 35 is fixed to the lower end of the vertical support plate 33. Multiple bolt holes for connecting the first curtain wall unit 1 and the second curtain wall unit 2 are provided on the support plate 35. Two tension screw rods 36 are fixedly connected to the vertical support plate 33. The two tension bolts are respectively arranged on both sides of the vertically elongated hole. The heights of the two tension screw rods 36 are different to match two second curtain wall units 2 with different heights at the diagonal corners. The axis of the tension screw rod 36 is in the same vertical plane as the axis of one of the bolt holes. The tension screw rod 36 is parallel to the support plate 35 and is arranged above the support plate 35. On the side where two adjacent first curtain wall units 1 and second curtain wall units 2 are close to each other, the same two connecting units 3 are connected. Four adjacent first curtain wall units 1 and second curtain wall units 2 are connected to the same connecting unit 3. One connecting unit 3 in the middle of the building main body is connected to two first curtain wall units 1 and two second curtain wall units 2.

[0050] Refer to Figure 6 and Figure 7, the first frame is connected with a first connecting plate 13, and the second frame is connected with a second connecting plate 23. The second connecting plate 23 is in a "7" shape. Two raised bosses 37 are provided on the upper part of the support plate 35. The two bosses 37 are arranged at intervals, so that the upper surface of the support plate 35 is divided into two groups of planes with different heights. The support plate 35 has two specifications, and the positions of the bosses 37 of the two specifications are different to match the first connecting plate 13 and the second connecting plate 23 at different positions. Correspondingly, the vertical movement support plate 33 also has two specifications, and the positions of the tensioning screws 36 on the two specifications of the vertical movement support plate 33 are different to match the second connecting plate 23 at different positions. The first connecting plate 13 and the second connecting plate 23 connected to the same support plate 35 are staggered in the horizontal direction to avoid interference. The specification of the support plate 35 matches the specification of the vertical movement support plate 33 to form two specifications of connection units 3. The first connecting plate 13 is closely attached to the upper surface of the support plate 35 and is fixedly connected to the bolt holes of the support plate 35 through bolts. The lower surface of the second connecting plate 23 is closely attached to the upper surface of the support plate 35. The second connecting plate 23 is fixedly connected to the bolt holes of the support plate 35 through bolts. One end of the second connecting plate 23 away from the second frame is closely attached to the vertical movement support plate 33 and is connected to the tensioning screw 36 through a nut. During installation, first use the nut to fasten the second connecting plate 23 to the vertical movement support plate 33, and then use bolts to fasten the second connecting plate 23 to the support plate 35. The bolts are at the end of the nut facing away from the vertical movement support plate 33 and the distance between the head of the bolt and the nut is less than 1 mm. After the bolts are tightened, they can prevent the nut from loosening. The cooperation of the nut and the tensioning bolt provides the tensioning force of the second curtain wall unit 2 towards the building main body, so that the second sealing strip 21 is automatically pressed against the first sealing strip 11 during the installation of the second curtain wall unit 2, which is convenient for installation.

[0051] Referring to Figure 8 , the embodiment of the present application also provides an installation method for an embedded unitized curtain wall structure, including the following steps:

[0052] Installation of the connection unit 3: Measure and set out the lines on site according to the drawings to determine the specific positions of the first curtain wall unit 1 and the second curtain wall unit 2 installed on the building main body; then drill holes and use expansion bolts to fixedly install the transverse movement support plate 31 on the building main body, and then use nuts to install the vertical movement support plate 33 on the transverse movement support plate 31.

[0053] Installation of the first curtain wall unit 1: Install the first curtain wall unit 1 vertically and horizontally in a staggered manner on the connection unit 3, use bolts to install the first connecting plate 13 on the support plate 35, and then adjust the transverse movement support plate 31 and the vertical movement support plate 33 according to the design position of the first curtain wall unit 1, so that the installation error of each first curtain wall unit 1 is within the allowable error range.

[0054] Installation of the second curtain wall unit 2: Embed the second curtain wall units 2 one by one into the space surrounded by the first curtain wall units 1, then install the second connecting plate 23 onto the tension bolts using nuts, and pull the second curtain wall units 2 towards the building main body to press the first sealing strip 11 and the second sealing strip 21 tightly together. Then, install the second connecting plate 23 onto the support plate 35 using bolts. During the installation of the second curtain wall units 2, glue A flows out of the first sealing strip 11 and glue B flows out of the second sealing strip 21. Glue A and glue B are mixed into AB glue outside the first sealing strip 11 and the second sealing strip 21, and fill the space surrounded by the first frame, the second frame, the first sealing strip 11 and the second sealing strip 21. During the installation of the second curtain wall units 2, if it is found that glue continuously leaks from the gap between the first curtain wall units 1 and the second curtain wall units 2, use tape to seal the leakage point, and then remove the tape after the glue solidifies.

[0055] Curtain wall cleaning: After the installation of both the first curtain wall units 1 and the second curtain wall units 2 is completed, clean the curtain wall and check for any leakage during the cleaning process. If there is leakage, apply a dissolving agent around the second curtain wall unit 2 adjacent to the leakage point to dissolve the AB glue, then remove the second curtain wall unit 2, clean the AB glue around the removed second curtain wall unit 2, and clean the AB glue on the first curtain wall unit 1 that contacts the removed second curtain wall unit 2. Then, install the removed second curtain wall unit 2 back to its original position and inject glue for sealing around the second curtain wall unit 2.

[0056] It should be noted that after the installation of the second curtain wall units 2, if the vertical supporting force of the curtain wall structure is insufficient or the support of the curtain wall structure is unstable, weld the nut on the vertical movement screw 34 firmly to the vertical movement support plate 33.

[0057] The implementation principle of the embodiments of this application is as follows: Since the first curtain wall unit 1 and the second curtain wall unit 2 are installed alternately, and the first curtain wall unit 1 is installed first and then the second curtain wall unit 2, the second curtain wall unit 2 can be installed in an embedded manner, providing the basic conditions for the separation and mixing of glue A and glue B. After the second curtain wall unit 2 is installed, glue A is pressed out of the first sealing strip 11, and glue B is pressed out of the second sealing strip 21. Glue A and glue B come into contact and mix in the space surrounded by the first frame, the second frame, the first sealing strip 11 and the second sealing strip 21 to form AB glue, which fills the gap between the first curtain wall unit 1 and the second curtain wall unit 2. After coagulation, the gap between the first curtain wall unit 1 and the second curtain wall unit 2 is sealed, realizing the anti-seepage function and reducing the leakage accidents of the curtain wall structure. Moreover, since this application does not require injecting glue into the gap between the first curtain wall unit 1 and the second curtain wall unit 2 after the second curtain wall unit 2 is installed, the gap between the first curtain wall unit 1 and the second curtain wall unit 2 can be designed to be smaller, and the installation of the first curtain wall unit 1 and the second curtain wall unit 2 is more compact, which can reduce the occurrence of leakage accidents of the curtain wall structure.

[0058] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
