Abstract
Description
Technical Field
[0001] This application relates to the technical field of glass curtain walls, and in particular to a spliced glass curtain wall. Background Technology
[0002] A glass curtain wall is a type of curtain wall that is assembled from glass and building framing to replace the walls of a building. By replacing part of the walls with glass curtain walls, the brightness inside the building can be increased, making it easier to work inside the building.
[0003] A search revealed Chinese Patent Publication No. CN113431235B, which discloses a glass curtain wall installation structure. The structure includes a fixing plate with a first adjustment mechanism, two second adjustment mechanisms, and four connecting mechanisms. Each connecting mechanism comprises a hollow cylinder, a snap-fit component, a spring, and a safety component. The snap-fit component is slidably disposed within the hollow cylinder and matches the glass panel. The spring is located between the lower end of the snap-fit component and a telescopic component. The safety component is located at the end of the hollow cylinder. The snap-fit component includes a circular piece, four protruding pieces, four spring pieces, and four locking blocks. The four spring pieces are evenly arranged in a ring on the upper end of the circular piece, and the four locking blocks are respectively connected to the four spring pieces. The hollow cylinder has movable grooves and positioning grooves on its side that match the protruding pieces and locking blocks. This invention makes glass panel installation more convenient and faster, reduces the need for construction personnel, lowers manpower consumption, and effectively improves the stability of the glass panel during and after installation.
[0004] Regarding the aforementioned technologies, the inventors discovered the following drawbacks: During the installation of the glass curtain wall, it is necessary to align the four connecting holes on the glass panel with the connecting mechanism on the building keel. Since the installation of the glass curtain wall is a high-altitude operation, and the diameter of the connecting mechanism is not much different from the diameter of the connecting holes on the glass panel, it is difficult to align the four connecting holes on the glass panel with the connecting mechanism on the building keel, which is not conducive to the rapid installation of the glass curtain wall. Therefore, improvements are needed. Summary of the Invention
[0005] To improve the installation efficiency of glass curtain walls, this application provides a splicing glass curtain wall.
[0006] The present application provides a splicing glass curtain wall, which adopts the following technical solution: a splicing glass curtain wall includes a keel frame with multiple plug columns and a glass panel with multiple plug holes. The plug columns and plug holes correspond one-to-one and are plugged in. The end of the plug column away from the keel frame is provided with a sliding groove that penetrates the side wall of the plug column. A guide plate is slidably embedded in the sliding groove along the axial direction of the plug column. The top of the guide plate is at the same height as the top of the plug-in post, the side wall of the guide plate is on the same arc surface as the side wall of the plug-in post, the cross-sectional area of the middle part of the guide plate gradually increases from the plug-in post to the keel frame, and the end of the guide plate facing the keel frame is semi-circular. The end of the guide plate away from the keel frame is connected to the plug-in post by a return spring, and can extend out of the slide groove under the elastic force of the return spring. The end of the guide plate facing the keel frame is connected to the first elastic unit by sliding radially along the plug-in post. When the first elastic unit is in its natural state, it will extend part of the slide groove. The glass plate can push the guide plate to slide into the slide groove through the part of the first elastic unit that extends out of the slide groove. The first elastic unit has a first inclined surface at one end extending out of the chute, which allows the glass plate to slide down towards the keel frame. When the guide plate is completely submerged in the chute, the glass plate can be compressed into the chute by the first inclined surface.
[0007] Optionally, the first elastic unit includes a first limiting block that is radially slidably connected to the guide plate along the plug-in post. The first limiting block is also connected to the guide plate via a first spring, the length direction of which is the same as the radial direction of the plug-in post. The end of the chute facing the keel frame is provided with an interconnected transition groove and a locking groove. The depth of the transition groove gradually increases from the insertion post to the keel frame, and the depth of the locking groove is greater than the depth of the transition groove. When one end of the first limiting block is embedded in the slide groove, the other end of the first limiting block will extend out of the slide groove and block the movement of the glass plate. The first inclined surface is provided on the end of the first limiting block and is spaced apart from the slide groove. When the first limiting block slides from the slide groove to the slot in the transition groove, the first spring will gradually return to its natural state, causing the first inclined surface to extend into the slide groove. When the first limiting block slides to the slot, the glass plate can press the first limiting block into the slot through the first inclined surface, and the first spring will be compressed so that the first limiting block is pressed against the wall of the insertion hole.
[0008] Optionally, a first receiving groove is provided on the groove wall at the end of the chute away from the keel frame. A second elastic unit is provided in the first receiving groove. The second elastic unit includes a second limiting block that is slidably embedded in the first receiving groove along the radial direction of the plug-in post. The second limiting block is connected to the plug-in post by a second spring. The length direction of the second spring is the same as the radial direction of the plug-in post. The guide plate is provided with a limiting groove. When the second spring is in its natural state, the second limiting block will be inserted into the first receiving groove and the limiting groove.
[0009] Optionally, the wall of the limiting groove is provided with a first pressing surface that is inclined. When the second limiting block sinks into the limiting groove to the first pressing surface, the glass plate can push the first limiting block toward the keel frame so that the first pressing surface on the guide plate presses the second limiting block into the first receiving groove.
[0010] Optionally, when the second spring is in its natural state, the end of the second limiting block away from the first receiving groove will extend out of the limiting groove and have a second inclined surface. When the glass plate slides toward the keel frame, the second limiting block can be pressed down to the first pressing surface through the second inclined surface. The first pressing surface will press the second limiting block into the first receiving groove through the second inclined surface.
[0011] Optionally, a second receiving groove is provided on the middle groove wall of one of the plug-in pins, located between the first receiving groove and the transition groove. A third elastic unit is provided in the second receiving groove. The third elastic unit includes a third limiting block that is slidably embedded in the second receiving groove along the radial direction of the plug-in pin. The third limiting block is connected to the plug-in pin by a third spring. The length direction of the third spring is the same as the radial direction of the plug-in pin. When the third spring is in its natural state, the third limiting block will be inserted into the second receiving groove and the limiting groove. The end of the third limiting block away from the second receiving groove will extend out of the limiting groove and can press the glass plate against the keel frame.
[0012] Optionally, the wall of the limiting groove is provided with a second pressing surface that is inclined. When the third limiting block sinks into the limiting groove to the second pressing surface, the guide plate that is reset under the elastic force of the reset spring will press the third limiting block into the second receiving groove through the second pressing surface.
[0013] In summary, this application includes the following beneficial technical effects: 1. Before the plug-in post is aligned with the plug-in hole, the guide plate, due to its small end face area, will be easy to insert into the plug-in hole. The guide plate can also gradually fine-tune the position of the glass plate so that when the glass plate slides to the plug-in post, the plug-in hole can be aligned with the plug-in post, so that the glass plate can be installed on the keel frame. 2. When the glass plate is installed on the keel frame, the glass plate will press the first limiting block into the slot through the first inclined surface. The first spring will be compressed and make the first limiting block press against the hole wall of the insertion hole, which improves the stability of the glass plate. 3. When the insertion hole aligns with the guide plate, the second spring will be in its natural state, and the second limiting block will be inserted into the first receiving groove and the limiting groove, so that the guide plate is limited and fixed in the sliding groove, so that the glass plate can slide stably on the guide plate during installation, and the guide plate can also gradually adjust the position of the glass plate. 4. When the glass plate slides toward the keel frame, the second limiting block can be pressed down to the first pressing surface through the second inclined surface. The first pressing surface will press the second limiting block into the first receiving groove through the second inclined surface, so that the guide plate can be stored in the slide groove. 5. After the glass plate is installed on the keel frame, the guide plate will sink into the slide groove. At this time, the limiting groove will correspond to the second receiving groove. The third spring will gradually return to its natural state. The third limiting block will be inserted into the second receiving groove and the limiting groove. The end of the third limiting block away from the second receiving groove will extend out of the limiting groove and can press the glass plate against the keel frame, thereby improving the stability of the glass plate.

[0016] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.
[0017] This application discloses a modular glass curtain wall. For example... Figure 1 and Figure 2 As shown, a spliced glass curtain wall includes a frame 1 and several glass panels 3. Multiple horizontally arranged plug-in columns 2 are installed on the frame 1. Each of the four corners of the glass panel 3 is provided with a plug-in hole 31. The plug-in columns 2 correspond one-to-one with the plug-in holes 31 and are plugged in to fit together.
[0018] A guide plate 21 is provided at the end of the plug-in post 2 away from the keel frame 1. The end face area of the guide plate 21 away from the plug-in post 2 is smaller than the end face area of the plug-in post 2. Before the plug-in post 2 is aligned with the plug-in hole 31, the guide plate 21, due to its smaller end face area, will be easier to insert into the plug-in hole 31.
[0019] The top of the guide plate 21 is at the same height as the top of the insertion post 2, and the side wall of the guide plate 21 is on the same arc surface as the side wall of the insertion post 2. The cross-sectional area of the middle part of the guide plate 21 gradually increases from the insertion post 2 towards the keel frame 1. When the glass plate 3 on the guide plate 21 slides closer to the insertion post 2, the guide plate 21 will gradually make fine adjustments to the position of the glass plate 3, so that when the glass plate 3 slides to the insertion post 2, the insertion hole 31 can be aligned with the insertion post 2, so that the glass plate 3 can be installed on the keel frame 1.
[0020] The end of the plug-in post 2 away from the keel frame 1 is provided with a groove 22 that runs through the side wall of the plug-in post 2. The end of the guide plate 21 facing the keel frame 1 is semi-circular, so that the guide plate 21 wraps around the plug-in post 2, ensuring that the guide plate 21 can only slide along the length of the groove 22 within the groove 22.
[0021] After the glass panel 3 is installed on the frame 1, the guide plate 21 can slide into the groove 22, so that the guide plate 21 is stored on the plug column 2, so as to ensure the aesthetics of the glass curtain wall and avoid the exposed guide plate 21 from affecting the use of the glass curtain wall.
[0022] The end of the guide plate 21 facing away from the keel frame 1 is connected to the plug-in post 2 via a return spring 211. The length direction of the return spring 211 is the same as the axial direction of the plug-in post 2. When the return spring 211 is in its natural state, the end of the guide plate 21 facing away from the keel frame 1 will extend out of the slide groove 22 so that the guide plate 21 can guide the installation of the glass plate 3.
[0023] The end of the plug post 2 away from the keel frame 1 is provided with a storage groove 23, and the reset spring 211 is located in the storage groove 23, which realizes the storage of the reset spring 211 and avoids the exposure of the reset spring 211.
[0024] like Figures 2 to 5 As shown, the guide plate 21 is provided with a first elastic unit 4 at the end facing the keel frame 1. When the first elastic unit 4 is in its natural state, it extends part of the slide groove 22. When the glass plate 3 on the guide plate 21 slides towards the keel frame 1, it can push the part of the first elastic unit 4 that extends out of the slide groove 22. The first elastic unit 4 will drive the guide plate 21 to slide and sink into the slide groove 22, thus realizing the automatic storage of the guide plate 21.
[0025] The first elastic unit 4 has a first inclined surface 42 on one end extending out of the slide groove 22. When the guide plate 21 is completely sunk into the slide groove 22, the glass plate 3 will continue to slide closer to the keel frame 1. At this time, the guide plate 21 will remain stationary, and the glass plate 3 will press the first elastic unit 4 into the slide groove 22 through the first inclined surface 42. The first elastic spring will be compressed and pressed against the glass plate 3, so that the glass plate 3 is stably installed on the keel frame 1.
[0026] The first elastic unit 4 includes a first limiting block 41, on which a dovetail block 43 is installed. The guide plate 21 has a dovetail groove 44 at one end facing the keel frame 1. The dovetail block 43 is radially slidably embedded in the dovetail groove 44 along the plug-in post 2, thereby realizing the sliding connection between the first limiting block 41 and the guide plate 21.
[0027] The dovetail block 43 on the first limiting block 41 is connected to the guide plate 21 by the first spring 45. The length direction of the first spring 45 is the same as the radial direction of the plug post 2, and the first spring 45 is located in the dovetail groove 44.
[0028] The sliding groove 22 is provided with a transition groove 46 and a locking groove 47 that are interconnected at one end facing the keel frame 1. The depth of the transition groove 46 gradually increases from the insertion post 2 toward the keel frame 1, and the depth of the locking groove 47 is greater than the depth of the transition groove 46.
[0029] When one end of the first limiting block 41 is embedded in the slide groove 22, the other end of the first limiting block 41 will extend out of the slide groove 22. The first inclined surface 42 is provided on the end of the first limiting block 41 and is spaced apart from the slide groove 22. When the glass plate 3 slides closer to the keel frame 1, it will drive the guide plate 21 to sink into the slide groove 22 through the first limiting block 41.
[0030] Subsequently, the first limiting block 41 will slide into the transition groove 46 and slide into the slot 47. The first spring 45 will gradually return to its natural state, causing the first inclined surface 42 to extend into the slide groove 22. Then, the first limiting block 41 will slide to the slot 47. At this time, the glass plate 3 can press the first limiting block 41 into the slot 47 through the first inclined surface 42. The first spring 45 will be compressed, causing the first limiting block 41 to press against the hole wall of the insertion hole 31, improving the stability of the glass plate 3. The first limiting block 41 will also cause the guide plate 21 to be locked and fixed in the slide groove 22, achieving stable storage of the guide plate 21.
[0031] A first receiving groove 24 is provided on the groove wall at one end of the slide groove 22 away from the keel frame 1. A second elastic unit 5 is provided in the first receiving groove 24. The second elastic unit 5 includes a second limiting block 51 that is slidably embedded in the first receiving groove 24 along the radial direction of the plug-in post 2. The second limiting block 51 is connected to the plug-in post 2 by a second spring 53. The length direction of the second spring 53 is the same as the radial direction of the plug-in post 2. The reset spring 211 is offset from the second limiting block 51.
[0032] The guide plate 21 is provided with a limiting groove 212. When the second spring 53 is in its natural state, the second limiting block 51 will be inserted into the first receiving groove 24 and the limiting groove 212, so that the guide plate 21 is limited and fixed in the sliding groove 22, so that the glass plate 3 can slide stably on the guide plate 21 during the installation process, and the guide plate 21 can also gradually adjust the position of the glass plate 3.
[0033] The wall of the limiting groove 212 is provided with a first pressing surface 213 that is inclined. When the glass plate 3 slides to the second limiting block 51, the worker can press the second limiting block 51 in the limiting groove 212 down to the first pressing surface 213. Then the glass plate 3 will continue to move forward and push the first limiting block 41 to the keel frame 1. The first limiting block 41 will drive the guide plate 21 to move synchronously. The first pressing surface 213 on the guide plate 21 will press the second limiting block 51 into the first receiving groove 24 to ensure that the guide plate 21 can be properly stored in the slide groove 22.
[0034] It is worth noting that when the second spring 53 is in its natural state, the end of the second limiting block 51 that is away from the first receiving groove 24 will extend out of the limiting groove 212 and have a second inclined surface 52. When the glass plate 3 slides toward the keel frame 1, the second limiting block 51 can be pressed down to the first pressing surface 213 through the second inclined surface 52. The first pressing surface 213 will press the second limiting block 51 into the first receiving groove 24 through the second inclined surface 52. There is no need for workers to manually press the second limiting block 51, so that the glass plate 3 can automatically complete the storage of the guide plate 21 during the installation process.
[0035] One of the plug-in pins 2 has a second receiving groove 25 located between the first receiving groove 24 and the transition groove 46 on the middle groove wall of the groove 22. The second receiving groove 25 is provided with a third elastic unit 6. The third elastic unit 6 includes a third limiting block 61 that is slidably embedded in the second receiving groove 25 along the radial direction of the plug-in pin 2. The third limiting block 61 is connected to the plug-in pin 2 by a third spring 62. The length direction of the third spring 62 is the same as the radial direction of the plug-in pin 2.
[0036] During the installation of glass plate 3, the worker will press the third limiting block 61 into the second receiving groove 25, so that the third spring 62 is in a compressed state. After the glass plate 3 is installed on the keel frame 1, the guide plate 21 will sink into the sliding groove 22. At this time, the limiting groove 212 will correspond to the second receiving groove 25. The third spring 62 will gradually return to its natural state. The third limiting block 61 will be inserted into the second receiving groove 25 and the limiting groove 212, so that the guide plate 21 is further limited and fixed. The end of the third limiting block 61 away from the second receiving groove 25 will extend out of the limiting groove 212 and can press the glass plate 3 against the keel frame 1, thereby improving the stability of the glass plate 3.
[0037] The groove wall of the limiting groove 212 is provided with a second pressing surface 214 that is inclined. When the worker presses the third limiting block 61 in the limiting groove 212 down to the second pressing surface 214, the glass plate 3 can be removed horizontally. The first spring 45 will return to its natural state and cause the first limiting block 41 to disengage from the slot 47. The reset spring 211 will gradually return to its natural state, so that the guide plate 21 moves to reset. The guide plate 21 will press the third limiting block 61 into the second receiving groove 25 through the second pressing surface 214, so that the third limiting block 61 is stored.
[0038] The implementation principle of a splicing glass curtain wall according to an embodiment of this application is as follows: During the installation of the glass panel 3, the worker first aligns the guide plate 21 with the insertion hole 31. Due to its small end face area, the guide plate 21 is easy to insert into the insertion hole 31. As the glass panel 3 slides closer to the keel frame 1, the guide plate 21 will gradually make fine adjustments to the position of the glass panel 3, so that when the glass panel 3 slides to the insertion post 2, the insertion hole 31 can be aligned with the insertion post 2 so that the insertion post 2 can be accurately inserted into the insertion hole 31.
[0039] Then, the glass plate 3 first presses the second limiting block 51 down to the first pressing surface 213 through the second inclined surface 52, and then pushes the first limiting block 41 towards the keel frame 1. The first limiting block 41 will drive the guide plate 21 to move synchronously. The guide plate 21 will press the second inclined surface 52 through the first pressing surface 213, so that the second limiting block 51 sinks into the first receiving groove 24.
[0040] The worker will then press the third limiting block 61 into the second receiving groove 25, and the first limiting block 41 will slide into the transition groove 46 and slide towards the slot 47. The first spring 45 will gradually return to its natural state, allowing the first inclined surface 42 to extend into the sliding groove 22. When the first limiting block 41 slides to the slot 47, the glass plate 3 will continue to slide, pressing the first limiting block 41 into the slot 47 through the first inclined surface 42. The first spring 45 will be compressed, causing the first limiting block 41 to press against the wall of the insertion hole 31. The guide plate 21 will be completely submerged into the sliding groove 22. At the same time, the limiting groove 212 will correspond to the second receiving groove 25, the third spring 62 will gradually return to its natural state, and the third limiting block 61 will be inserted into the second receiving groove 25 and the limiting groove 212, pressing the glass plate 3 against the keel frame 1.
[0041] In summary, workers only need to connect the insertion hole 31 on the glass panel 3 with the guide plate 21 and push the glass panel 3 towards the keel frame 1 to quickly install the glass panel 3 onto the keel frame 1, thereby improving the installation efficiency of the glass curtain wall.
[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.

The first pressing surface (213) will press the second limiting block (51) into the first receiving groove (24) through the second inclined surface (52).
4. A modular glass curtain wall according to claim 1, characterized in that: One of the plug-in pins (2) has a second receiving groove (25) located between the first receiving groove (24) and the transition groove (46) on the middle groove wall of the groove (22). The second receiving groove (25) is provided with a third elastic unit (6). The third elastic unit (6) includes a third limiting block (61) that is slidably embedded in the second receiving groove (25) along the radial direction of the plug-in pin (2). The third limiting block (61) is connected to the plug-in pin (2) by a third spring (62). The length direction of the third spring (62) is the same as the radial direction of the plug-in pin (2). When the third spring (62) is in its natural state, the third limiting block (61) will be inserted into the second receiving groove (25) and the limiting groove (212). The end of the third limiting block (61) away from the second receiving groove (25) will extend out of the limiting groove (212) and can bring the glass plate (3) against the keel frame (1).
5. A spliced glass curtain wall according to claim 4, characterized in that: The wall of the limiting groove (212) is provided with a second pressing surface (214) that is inclined. When the third limiting block (61) sinks into the limiting groove (212) to the second pressing surface (214), the guide plate (21) that is reset under the elastic force of the reset spring (211) will press the third limiting block (61) into the second receiving groove (25) through the second pressing surface (214).
