Description

Technical Field

[0001] This application relates to the field of curtain wall technology, and more particularly to a glass curtain wall installation structure. Background Technology

[0002] A glass curtain wall refers to a building's exterior envelope or decorative structure, consisting of a supporting structural system that allows for a certain degree of displacement relative to the main structure and does not share the loads of the main structure. Installing glass curtain walls on building exteriors is an aesthetically pleasing and novel method of building wall decoration, and a prominent feature of the modernist high-rise building era.

[0003] Existing glass curtain walls can be categorized into various forms based on their installation methods, including framed curtain walls, unitized curtain walls, all-glass curtain walls, and point-supported curtain walls. Among these, point-supported curtain walls commonly utilize point-supported connectors. After the keel frame is constructed on the building's exterior surface, multiple point-supported connectors are installed onto the keel frame according to the design drawings. Then, fasteners are used to connect the four corners of the glass curtain wall to four adjacent point-supported connectors, ensuring a stable installation of the glass curtain wall on the building's exterior.

[0004] The connection between the glass curtain wall and the keel frame typically uses fasteners such as bolts and nuts. The point-fitting connector has a first mounting hole at its claw end, and a second mounting hole running through the glass curtain wall. By aligning the first mounting hole with the second mounting hole, inserting the bolt into both holes, and then locking the threaded end of the bolt with a nut, a secure connection between the glass curtain wall and the point-fitting connector can be achieved. However, due to the large number of glass curtain walls on the entire building's exterior wall, using fasteners to connect each glass curtain wall to the point-fitting connector significantly impacts the overall curtain wall installation efficiency, resulting in a long construction period, which needs improvement. Summary of the Invention

[0005] Based on this, this application provides a glass curtain wall installation structure that can improve the installation efficiency of each glass curtain wall on the exterior wall of the entire building, thereby shortening the overall construction cycle.

[0006] The glass curtain wall installation structure provided in this application adopts the following technical solution:

[0007] A glass curtain wall installation structure includes a curtain wall frame fixed to the back of the glass curtain wall, a keel unit installed on the exterior wall of the building, and a plurality of connecting claws installed on the keel unit; wherein, the connecting claws include a base component and a plurality of extending claws arranged circumferentially on the base component, the outer end of the extending claws is provided with a through insertion hole, the insertion hole includes an opening area and a plurality of clearance areas evenly distributed on the outer periphery of the opening area;

[0008] Each corner of the curtain wall frame is equipped with a plug-in mechanism. The plug-in mechanism includes a connector fixed to the curtain wall frame and a plug-in that is movably set in the connector. The plug-in is plugged into the opening area. Multiple limiting plates are evenly distributed on the outer periphery of the plug-in. The limiting plates are plugged into the avoidance area.

[0009] A rotation reset structure is provided between the plug and the connector to enable the plug to rotate naturally and allow the limiting plate to pass smoothly through the avoidance area as the plug approaches the connecting claw in the curtain wall frame and the plug abuts against the extension claw. After the limiting plate passes through the avoidance area, the limiting plate and the avoidance area are misaligned.

[0010] By adopting the above technical solution, after constructing the keel unit on the surface of the building's exterior wall and evenly installing each connecting claw, the curtain wall frame of the glass curtain wall is fixed to the adjacent connecting claw, enabling rapid installation of the glass curtain wall. During installation, by aligning the connector with the limiting hole, the curtain wall frame is forced to gradually approach the connecting claw. At this time, due to the misalignment of each limiting plate and each clearance area, the limiting plate can abut against the extension claw during the movement of the curtain wall frame, and the connector rotates naturally through the rotation reset structure. When the connector rotates to the position where the limiting plate and the clearance area are directly opposite, the connector can smoothly pass through the connector hole. Then, the rotation reset structure returns the connector to its original position. At this point, the limiting plate is misaligned with the clearance area, making it difficult for the connector to directly detach from the connector hole. This allows for rapid connection and fixation between the curtain wall frame and the connecting claw in a snap-fit ​​manner, without the need for auxiliary tools. The entire installation process is convenient and quick, improving the laying efficiency of each glass curtain wall on the entire building's exterior wall and shortening the overall construction cycle.

[0011] Optionally, the end face of the connector away from the curtain wall frame is provided with a movable groove, the plug-in is movably installed in the movable groove and can rotate freely, and the opening of the movable groove is provided with an anti-detachment part to limit the plug-in from detaching; the rotation reset structure includes an extension block fixed to the outer peripheral wall of the plug-in and a sliding groove opened in the inner peripheral wall of the movable groove, the sliding groove spirally extending around the central axis of the connector toward the end face of the connector; the extension block is matched and installed in the sliding groove and slides freely in the sliding groove.

[0012] By adopting the above technical solution, the movable groove allows the connector to rotate freely and move axially within the movable groove. During the installation of the glass curtain wall, the limiting plate and the avoidance area are initially misaligned. When the connector abuts against the extension claw, the connector can move upward to avoid the obstacle. Furthermore, the movement of the extension block within the sliding groove causes the connector to deflect along the extension direction of the sliding groove, so that the connector can rotate to a position where the limiting plate and the avoidance area are directly opposite each other. This allows the limiting plate to pass smoothly through the avoidance area, while the connector smoothly inserts into the connector hole and remains locked and fixed within the connector hole.

[0013] Optionally, the rotation reset structure also includes a first elastic member disposed between the plug and the inner wall of the movable groove, the first elastic member being used to force the plug to move away from the curtain wall frame.

[0014] By adopting the above technical solution, the first elastic element can always generate an elastic force acting on the plug-in, forcing the plug-in to move away from the curtain wall frame, thereby making the plug-in abut against the anti-detachment part in the initial state; and the extension block can abut against the inner wall of one end of the sliding groove. Through the processing design of the plug-in mechanism, when the extension block abuts against the inner wall of one end of the sliding groove, the limiting plate can be in a state of being misaligned with the avoidance area. Then, during the installation of the glass curtain wall, after the limiting plate passes through the avoidance area smoothly, the plug-in can naturally reset under the elastic force of the first elastic element, so that the limiting plate returns to the position misaligned with the avoidance area, so that the curtain wall frame and the extension claw can maintain the locking and limiting.

[0015] Optionally, the extension claw is provided with a telescopic mechanism, which includes a first rod fixed to the surface of the extension claw, a second rod movably inserted into the first rod, and a second elastic member disposed between the first rod and the second rod. When the final curtain wall frame is installed on the connecting claw, the second elastic member forces the second rod to press against the curtain wall frame, and the limiting plate presses against the back of the extension claw.

[0016] By adopting the above technical solution and setting up a telescopic mechanism, when the curtain wall frame is installed on the connecting claw and the limiting plate smoothly passes through the avoidance area, the curtain wall frame can squeeze the second rod to move inward and force the second elastic member to retract inward. Then, when the operator removes the external force, the force of the second elastic member acting on the second rod can force the curtain wall frame to move outward, thereby causing the limiting plate to abut against the back of the extension claw, realizing the locking and limiting between the curtain wall frame and the connecting claw. At the same time, the setting of the second elastic member can also improve the wind and earthquake resistance of the glass curtain wall installation structure and has excellent mechanical life.

[0017] Optionally, the extension claw includes a first claw portion, a second claw portion, and a third claw portion arranged sequentially. The first claw portion is integrally formed on the base component, and the second claw portion is rotatably connected to the first claw portion through a rotating mechanism. An insertion hole is opened in the third claw portion, and the third claw portion is slidably sleeved on the second claw portion. An adjustment mechanism is provided between the third claw portion and the second claw portion to realize the position adjustment between the third claw portion and the second claw portion.

[0018] By adopting the above technical solution, the angle between the first and second claws is changed by a rotating mechanism, and the relative position between the third and second claws is changed by an adjusting mechanism. This allows the position of the insertion hole to be altered, ensuring that the connector can still be smoothly inserted into the insertion hole even when there is an installation position deviation in the connector claw, thus facilitating the smooth installation of the glass curtain wall. Furthermore, when different sizes of glass curtain walls need to be installed at specific locations on the building's exterior wall, changing the position of the insertion hole also allows the glass curtain wall to be smoothly installed onto the connector claw.

[0019] Optionally, the rotating mechanism includes a rotating shaft passing through the first claw and the second claw, two limiting stops respectively disposed at both ends of the rotating shaft, and two third elastic members sleeved on the rotating shaft. One of the third elastic members is disposed between the limiting stop and the adjacent first claw, and the other third elastic member is disposed between the limiting stop and the adjacent second claw. The third elastic members are used to force the first claw and the second claw to abut against each other.

[0020] A positioning structure is provided between the limiting stop and the adjacent first claw and between the limiting stop and the adjacent second baffle; the second claw is equipped with a pushing member, which is located on the outside of the contact surface between the first claw and the second claw. When the curtain wall frame is installed on the connecting claw, the curtain wall frame forces the pushing member to enter between the first claw and the second claw, while the first claw and the adjacent limiting stop, and the second claw and the adjacent limiting stop are respectively kept in angular positioning by the positioning structure.

[0021] By adopting the above technical solution, in the initial state, the first claw and the second claw can remain in contact with each other under the elastic force of the third elastic member, and the two can rotate relative to each other; when the curtain wall frame is installed on the connecting claw, the curtain wall frame can force the pushing member to enter between the first claw and the second claw, and force the first claw and the second claw to move away from each other. At this time, the first claw and the adjacent limiting stop, and the second claw and the adjacent limiting stop can be fixed by the positioning structure, so as to realize the angular positioning between the first claw and the second claw, thereby improving the stability of the glass curtain wall after installation.

[0022] Optionally, the jacking member includes a load-bearing part and a jacking part connected together. The jacking part is located outside the contact surface between the first claw part and the second claw part, while the load-bearing part is exposed on the surface of the second claw part. The second claw part is provided with a first groove for the load-bearing part to move and a second groove for the jacking part to move. A guide surface is provided at the transition position between the first groove and the second groove to guide the jacking part into the space between the first claw part and the second claw part when the load-bearing part moves inward.

[0023] By adopting the above technical solution, during the installation of the curtain wall frame on the connecting claw, the curtain wall frame can abut against the load-bearing part and force the jacking member to move inward. Finally, the jacking member can abut against the guide surface and move along the guide surface towards the transition position between the first groove and the second groove, so that the jacking part can smoothly push open the first claw and the second claw, and force the first claw and the adjacent limiting stop, and the second claw and the adjacent limiting stop to maintain angular positioning through the positioning structure respectively.

[0024] Optionally, the positioning structure includes a first tooth and a matching second tooth, the first tooth being disposed on the limiting stop and the second tooth being disposed on the first claw portion / second claw portion.

[0025] By adopting the above technical solution, when the curtain wall frame is installed on the connecting claw and the jacking member is forced to enter between the first claw and the second claw, the second engagement of the first claw can engage with the first tooth of the adjacent limiting stop, and the second engagement of the second claw can also engage with the first tooth of the adjacent limiting stop, so as to limit the relative rotation between the first claw and the rotating shaft and between the second claw and the rotating shaft, thereby realizing the angular positioning between the first claw and the second claw.

[0026] Optionally, the limit stop and the rotating shaft can be detachably fixed by fastening components.

[0027] By adopting the above technical solution, after the glass curtain wall is installed on the connecting claw, the rotating shaft can be located in the gap between adjacent glass curtain walls. When the glass curtain wall needs to be disassembled for replacement, the fastening parts of the outer limiting stop are removed, the limiting stop is taken out, and the glass curtain wall can be taken out together with the third claw and the second claw that are fixed to it, so as to replace the glass curtain wall smoothly.

[0028] Optionally, the adjusting mechanism includes a threaded rod, a driven gear, and a turning gear. The threaded rod is rotatably mounted inside the third pawl and is threadedly connected to the second pawl. The driven gear is fixed to the threaded rod, and the turning gear is rotatably mounted in the third pawl, with a portion of the turning gear exposed outside the third pawl. The turning gear and the driven gear mesh with each other for transmission.

[0029] By adopting the above technical solution, the operator can turn the gear, which can drive the driven gear and the threaded rod connected to the driven gear to rotate, thereby causing the third claw to move closer to or further away from the second claw, so as to adjust the relative position between the second claw and the third claw, thereby changing the position of the insertion hole, so that the glass curtain wall can be smoothly installed on the connecting claw.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. By inserting the connector into the opening area, the limiting plate on the outside of the connector passes through the clearance area, and the connector rotates through the rotation reset structure, which can quickly connect and fix the curtain wall frame and the connecting claw in the form of snap-fit ​​limiting; the whole installation process is convenient and quick, which can improve the laying efficiency of each glass curtain wall on the exterior wall of the building and shorten the overall construction cycle.

[0032] 2. By setting a sliding groove, when the extension block moves in the sliding groove, the connector can be deflected along the extension direction of the sliding groove, so that the connector can rotate to the position where the limiting plate and the clearance area are directly opposite, so that the limiting plate can pass through the clearance area smoothly, and the connector can be smoothly inserted into the connector hole and kept locked in the connector hole.

[0033] 3. By setting up a jacking component, after the curtain wall frame is installed on the connecting claw, the curtain wall frame can force the jacking component to enter between the first claw and the second claw, and force the first claw and the second claw to move in opposite directions. At this time, the first claw and the adjacent limiting stop, and the second claw and the adjacent limiting stop can maintain angular positioning through the positioning structure, so as to improve the stability of the glass curtain wall after installation.

[0045] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0046] This application discloses a glass curtain wall installation structure.

[0047] Reference Figure 1 A glass curtain wall installation structure includes a curtain wall frame 1, a keel unit 2, and a connecting claw 3, while referring to... Figure 2 The keel unit 2 includes multiple wall ties 21 and multiple vertical steel ribs 22. All wall ties 21 are fixed to the building exterior wall 8 at equal intervals, and each vertical steel rib 22 is installed corresponding to each of the vertically arranged wall ties 21. Multiple connecting claws 3 are provided, and all connecting claws 3 are evenly distributed and installed on each vertical steel rib 22 for installing the curtain wall frame 1. In addition, the curtain wall frame 1 is fixed to the back of the glass curtain wall 9. During installation, the four corners of the curtain wall frame 1 are respectively fixed to the four connecting claws 3 that surround the adjacent areas, which can achieve a stable installation of the glass curtain wall 9.

[0048] Reference Figure 3The connecting claw 3 includes a base 31 and multiple extension claws 32. The base 31 is used for fixed connection with the vertical steel frame 22. In this embodiment, the installed glass curtain wall 9 is rectangular, so there are four extension claws 32, which are equidistantly arranged on the outer periphery of the base 31. In other feasible embodiments, the number of extension claws 32 may be three or five depending on the specific shape of the glass curtain wall 9, and is not limited to the number provided in this embodiment.

[0049] The extension claw 32 is provided with a through insertion hole 33, which is located at the end of the extension claw 32 away from the base member 31. The insertion hole 33 includes a through area 331 and a plurality of avoidance areas 332. The through area 331 has a circular cross-sectional shape, and the avoidance areas 332 are equidistantly arranged on the outer periphery of the through area 331. In this embodiment, the number of avoidance areas 332 is set to 4. In other feasible embodiments, the number of avoidance areas 332 may also be 3, 5, or 6, and is not limited to the number provided in this embodiment.

[0050] Reference Figure 4 The curtain wall frame 1 is provided with a plug-in mechanism 11 on the side away from the glass curtain wall 9. The number of plug-in mechanisms 11 is equal to the number of plug-in holes 33. The four sets of plug-in mechanisms 11 are distributed at the four corners of the curtain wall frame 1 and are used to cooperate with each plug-in hole 33 for plug-in positioning.

[0051] Reference Figure 5 The insertion mechanism 11 includes a connector 12 and a plug-in 13. The connector 12 is welded and fixed to the curtain wall frame 1. The end face of the connector 12 away from the curtain wall frame 1 is provided with a movable groove. The plug-in 13 is movably installed in the movable groove and can rotate freely in the movable groove. In addition, the opening of the movable groove is provided with an anti-detachment part 122 for limiting the plug-in 13 from detaching. The anti-detachment part 122 is integrally formed with the connector 12.

[0052] The outer diameter of the connector 13 is equal to the inner diameter of the through area 331, so that the connector 13 can be matched and inserted into the through area 331. Multiple limiting plates 131 are evenly distributed on the outer periphery of the connector 13. The number of limiting plates 131 is equal to the number of clearance areas 332, and the width of the limiting plate 131 is not greater than the width of the clearance area 332, so that the limiting plate 131 can pass smoothly through the clearance area 332.

[0053] In the initial state, each limiting plate 131 is misaligned with each avoidance area 332; a rotation reset structure 14 is provided between the plug-in member 13 and the connector 12 so that during the process of the curtain wall frame 1 approaching the connecting claw member 3 and the plug-in member 13 abutting against the extension claw 32, the plug-in member 13 can rotate naturally and allow the limiting plate 131 to pass smoothly through the avoidance area 332. In addition, between the time the limiting plate 131 passes through the avoidance area 332, the limiting plate 131 can return to the position misaligned with the avoidance area 332 so that the plug-in member 13 and the connecting claw member 3 are locked and limited.

[0054] Specifically, the rotation reset structure 14 includes an extension block 141 fixed to the outer peripheral wall of the connector 13 and a sliding groove 142 formed in the inner peripheral wall of the movable groove. The sliding groove 142 extends spirally around the central axis of the connector 12 toward one end face closer to the connector 12. The extension block 141 is fitted into the sliding groove 142 and can slide freely within the sliding groove 142. In addition, the rotation reset structure 14 also includes a first elastic member 143 disposed between the connector 13 and the inner wall of the movable groove. The first elastic member 143 is a soft spring and is always in a compressed state. It can abut against the connector 13 and force the connector 13 to move away from the curtain wall frame 1. Finally, the connector 13 can abut against the anti-detachment part 122, and the extension block 141 can abut against one end wall of the sliding groove 142.

[0055] Reference Figure 3 , Figure 5 During installation, as the curtain wall frame 1 moves towards the connecting claw 3, the limiting plate 131 first abuts against the surface of the extension claw 32, forcing the connector 13 to move into the movable groove and compressing the first elastic element 143 to contract and deform. As the connector 13 moves inward, it can deflect along the extension direction of the sliding groove 142. When it rotates to a position where the limiting plate 131 is directly opposite the clearance area 332, the limiting plate 131 smoothly enters the clearance area 332, and the connector 13 smoothly enters the through area 331. After the limiting plate 131 passes through the through area 331, the elastic force of the first elastic element 143 forces the connector 13 to move outward and reset, causing the limiting plate 131 to return to a state of misalignment with the clearance area 332. This makes it difficult for the connector 13 to directly detach from the extension claw 32, thus quickly fixing the curtain wall frame 1 and the connecting claw 3 through a snap-fit ​​limiting mechanism.

[0056] See also Figure 6The extension claw 32 is provided with a telescopic mechanism 34, which is located outside the insertion hole 33. The telescopic mechanism 34 includes a first rod 341, a second rod 342, and a second elastic member 343. The first rod 341 is fixed to the surface of the extension claw 32, that is, the side of the extension claw 32 away from the vertical steel rib 22. The second rod 342 is movably inserted into the first rod 341, and the second elastic member 343 is connected between the first rod 341 and the second rod 342. The second elastic member 343 is a hard spring, which can always generate an elastic force acting on the second rod 342 to force the second rod 342 to move away from the extension claw 32. Furthermore, the elastic force of the second elastic member 343 can be greater than the elastic force of the first elastic member 343.

[0057] During the installation of the glass curtain wall 9, when the connector 13 enters the through area 331, the curtain wall frame 1 can squeeze the second rod 342 to move inward and force the second elastic member 343 to contract and deform. After the limiting plate 131 passes through the avoidance area 332 smoothly, the external force acting on the glass curtain wall 9 is removed. The force of the second elastic member 343 acting on the second rod 342 can press against the curtain wall frame 1, forcing the curtain wall frame 1 to move away from the connecting claw 3, so that the limiting plate 131 presses against the back of the extension claw 32 to improve the stability of the glass curtain wall 9 after installation.

[0058] Additionally, returning Figure 3 The extended claw 32 of this application includes a first claw portion 35, a second claw portion 36 and a third claw portion 37. The first claw portion 35 is integrally formed on the outer peripheral surface of the base part 31. The second claw portion 36 is rotatably connected to the first claw portion 35 through a rotating mechanism 4. The third claw portion 37 is slidably sleeved on the second claw portion 36, and an adjustment mechanism 7 is provided between the third claw portion 37 and the second claw portion 36 to realize the position adjustment between the third claw portion 37 and the second claw portion 36.

[0059] The insertion hole 33 is opened on the third claw portion 37 and is located at the end of the third claw portion 37 away from the second claw portion 36, and the telescopic mechanism 34 is also provided on the third claw portion 37. When the glass curtain wall 9 is installed, by adjusting the relative angle between the first claw portion 35 and the second claw portion 36 and adjusting the relative position between the third claw portion 37 and the second claw portion 36, the position of the insertion hole 33 can be changed to overcome the positioning error during the installation of the connecting claw 3 and facilitate the installation of glass curtain walls 9 of different sizes.

[0060] Reference Figure 7The rotating mechanism 4 includes a rotating shaft 41, a limiting stop 42, and a third elastic member 43. The rotating shaft 41 passes through the first claw portion 35 and the second claw portion 36, and both ends of the rotating shaft 41 can be exposed outside the first claw portion 35 and the second claw portion 36, respectively. There are two limiting stops 42, which are respectively disposed at both ends of the rotating shaft 41. Each limiting stop 42 is detachably fixed to the rotating shaft 41 by a fastening member 44, so as to facilitate the assembly and disassembly of the limiting stop 42 and the rotating shaft 41.

[0061] Two third elastic elements 43 are provided, and the two third elastic elements 43 are respectively sleeved on the rotating shaft 41; one third elastic element 43 is located between the limiting stop 42 and the adjacent first claw 35, and the other third elastic element 43 is located between the limiting stop 42 and the adjacent second claw 36; the two third elastic elements 43 can respectively generate elastic forces acting on the first claw 35 and the second claw 36, forcing the first claw 35 and the second claw 36 to remain in contact with each other under normal conditions, so as to facilitate relative rotation between the first claw 35 and the second claw 36; it should also be noted that a damping pad (not shown in the figure) can also be placed between the first claw 35 and the second claw 36 to limit arbitrary rotation between the first claw 35 and the second claw 36.

[0062] Positioning structures 5 are provided between the limiting stop 42 and the adjacent first claw 35, and between the limiting stop 42 and the adjacent second claw 36. When the first claw 35 and the second claw 36 move in opposite directions, the first claw 35 abuts against the adjacent limiting stop 42, and the second claw 36 abuts against the adjacent second stop, thus maintaining angular positioning through the positioning structures 5. The specific structures of the two sets of positioning structures 5 are the same. This embodiment uses the positioning structure 5 between the first claw 35 and the limiting stop 42 as an example for explanation, and the other set of positioning structures 5 will not be described in detail.

[0063] Specifically, the positioning structure 5 includes a first tooth 51 and a matching second tooth 52. The first tooth 51 is integrally formed on the side of the limiting stop 42 facing the first claw portion 35, while the second tooth 52 is integrally formed on the side of the first claw portion 35 facing the adjacent limiting stop 42. Furthermore, a third elastic member 43 is located within the inner ring of the first tooth 51 and the second tooth 52. When the first claw portion 35 is subjected to force and moves away from the second claw portion 36, the first tooth 51 and the second tooth 52 can mesh with each other to position the rotation angle between the first claw portion 35 and the limiting stop 42.

[0064] In addition, the second claw 36 is also equipped with a pushing member 6. The pushing member 6 is located on the outside of the contact surface between the first claw 35 and the second claw 36. After the curtain wall frame 1 is installed on the connecting claw 3, the curtain wall frame 1 can force the pushing member 6 to squeeze between the first claw 35 and the second claw 36, thereby forcing the first claw 35 to engage with the adjacent outer limit stop 42 and the second claw 36 to engage with the adjacent outer limit stop 42, thus automatically completing the angular positioning between the first claw 35 and the second claw 36.

[0065] The second claw portion 36 has a first groove 361 and a second groove 362 inside. The first groove 361 extends in the same direction as the length of the second claw portion 36 and penetrates the side of the second claw portion 36 near the first claw portion 35. The second groove 362 is connected to the first groove 361 and extends perpendicularly through the surface of the second claw portion 36. The pushing member 6 includes an integrally formed load-bearing part 62 and a pushing part 61, which are perpendicularly arranged. The pushing part 61 is movably located inside the first groove 361, and one end of the pushing part 61 away from the load-bearing part 62 extends to the outer side of the contact surface between the first claw portion 35 and the second claw portion 36. The load-bearing part 62 is movably located inside the second groove 362, and one end of the load-bearing part 62 away from the pushing part 61 is exposed on the surface of the second claw portion 36.

[0066] A guide surface 363 is provided at the transition position between the first groove 361 and the second groove 362. The guide surface 363 is located below the push member 6. When the curtain wall frame 1 is installed on the connecting claw 3, the curtain wall frame 1 can abut against the load-bearing part 62 to force the push member 6 to move inward. At this time, the push member 6 abuts against the guide surface 363. Under the guidance of the guide surface 363, the push part 61 moves towards the direction close to the rotating shaft 41, thereby opening the first claw part 35 and the second claw part 36 apart from each other, and using the positioning structure 5 to position the first claw part 35 and the second claw part 36 at an angle.

[0067] Reference Figure 8 The adjusting mechanism 7 includes a threaded rod 71, a driven gear 72, and a shifting gear 73. The threaded rod 71 is rotatably mounted inside the third claw portion 37 and is threadedly connected to the second claw portion 36. The driven gear 72 is fixed to the end of the threaded rod 71 away from the second claw portion 36, while the shifting gear 73 is rotatably connected to the third claw portion 37. The shifting gear 73 and the driven gear 72 mesh with each other to drive the third claw portion 37 to move towards / away from the second claw portion 36. In addition, the shifting gear 73 is partially exposed on the outer side of the third claw portion 37, which allows the operator to manually shift it to easily adjust the position of the third claw portion 37 and the insertion hole 33.

[0068] The implementation principle of a glass curtain wall installation structure in this application is as follows:

[0069] During installation, the wall ties 21 are fixed at equal intervals to the exterior wall 8 of the building, and the vertical steel ribs 22 are installed on the vertically arranged wall ties 21, so that the vertical steel ribs 22 are arranged at equal intervals on the exterior wall surface; then the connecting claws 3 are evenly distributed and installed on the vertical steel ribs 22, so that the four corners of the curtain wall frame 1 are respectively fixed to the four connecting claws 3 that enclose the adjacent areas.

[0070] During the installation of the glass curtain wall 9, a force is directly applied to the glass curtain wall 9, causing the glass curtain wall 9 and the curtain wall frame 1 to move towards the connecting claw 3. The limiting plate 131 on the periphery of the plug 13 first abuts against the extension claw 32, causing the plug 13 to move inward under force. During the movement of the plug 13, the extension block 141 deflects along the extension direction of the sliding groove 142, enabling the plug 13 to rotate to a position directly opposite the limiting plate 131 and the clearance area 332. At this time, the limiting plate 131 can smoothly enter the clearance area 332, and the plug 13 can smoothly enter the opening area 331.

[0071] After the limiting plate 131 passes through the clearance area 332, the connector 13, under the elastic action of the first elastic member 143, causes the limiting plate 131 to return to the state of being misaligned with the clearance area 332, removing the external force acting on the glass curtain wall 9. The second elastic member 343 forces the second rod 342 to move outward, driving the curtain wall frame 1 to move away from the extension claw 32, so that the limiting plate 131 can abut against the back of the extension claw 32, so that the curtain wall frame 1 and the extension claw 32 can maintain a locking and limiting connection. The entire installation process is convenient and quick, requiring no auxiliary tools, which helps to improve the laying efficiency of each glass curtain wall 9 on the entire building exterior wall 8 and shorten the overall construction cycle.

[0072] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
