Description

Technical Field

[0001] The present application relates to the field of building curtain walls, and in particular to a fast-replaceable curtain wall panel clip-on structure. Background Art

[0002] At present, with the rapid development of the national economy and the continuous improvement of people's living standards, as well as the improvement of architects' design concepts, buildings are increasingly developing towards high-rise, high-end and multi-functional directions, and curtain walls are beginning to be installed on the exterior walls of buildings to play a lightweight wall with decorative effect.

[0003] Currently, a keel frame with several rectangular frames is pre-installed on the exterior wall of the building. Prefabricated connecting parts such as metal baffles or corner brackets are fixed in the rectangular frames of the keel. Then, screws or blind rivets are used to penetrate the curtain wall panels and fix them to the metal baffles.

[0004] When installing a large number of curtain wall panels on the keel frame, workers need to carry a large number of screws or blind rivets with them, and use professional tools such as hand drills or rivet guns. They then take out the screws or blind rivets one by one and install them on the corresponding tools. They then pass the screws or rivets into the curtain wall panels and fix them to the connectors.

[0005] The above-mentioned existing technical solutions have the following defects: in the process of installing a large number of curtain wall panels on the exterior wall of a building, such repeated operations not only slow down the construction efficiency of the overall curtain wall project, but also cause damage to the curtain wall panels after the screws or blind rivets are driven into the curtain wall panels. When the curtain wall panels are damaged, the screws or blind rivets need to be removed one by one, which is not conducive to the subsequent repair and replacement of the curtain wall panels. Summary of the Invention

[0006] In order to facilitate the installation of curtain wall panels and facilitate their subsequent maintenance and replacement, the present application provides a curtain wall panel clip-on structure that can be quickly replaced.

[0007] The above technical objectives of this application are achieved through the following technical solutions:

[0008] A fast-replaceable curtain wall panel clip-on structure is provided on a keel frame for mounting the panel body. The keel frame includes horizontal keels made of square tubes and arranged at intervals up and down. The keel frame is formed with a rectangular hole area. The panel body is adapted to and can be clipped into the rectangular hole area. The side walls of the horizontal keels are provided with strip-shaped holes.

[0009] The clamping structure includes a top connecting component and a bottom connecting component arranged in the strip-shaped hole, and the top connecting component and the bottom connecting component in two adjacent transverse keels are used to install a panel body;

[0010] The top connection assembly includes a clamping block fixed on the panel body and a clamping assembly arranged in the strip hole and extending out of the rectangular hole area. The clamping block is trapezoidal and the top surface length is greater than the bottom surface length. After the clamping block is clamped into the clamping assembly, the clamping assembly is pressed against the clamping block.

[0011] The bottom connection assembly includes a plug rod movably arranged on the top of the transverse keel. When the plug rod is at its lowest height, its upper end surface is not higher than the upper surface of the transverse keel. A socket is opened on the bottom side of the panel body, and the plug rod can be inserted into the socket.

[0012] By adopting the above technical solution, the clamping block is fixedly connected to the plate surface of the panel body in advance, and then the panel body is embedded in the rectangular hole area of the keel frame. After the clamping block is connected to the clamping assembly, the clamping assembly and the clamping block are tightly pressed together to complete the installation of the top of the panel body. At this time, the plug-in rod is aligned with the socket at the bottom of the panel body. Then, the bottom connecting assembly is operated to insert the plug-in rod into the socket and lock the plug-in rod, so that the installation of the bottom of the panel body can be quickly completed. When the panel body needs to be removed from the keel frame, after releasing the bottom connecting assembly, the panel body is pulled toward the outside of the building exterior wall to complete the separation of the panel body from the keel frame. This will not cause damage to the panel body and is also convenient for disassembly and subsequent replacement and maintenance of the panel body.

[0013] Optionally, the clamping assembly includes a shell with an opening at the bottom, two limit blocks fixedly connected to opposite sides of the opening of the shell, a clamping member movably arranged in the shell and located between the two limit blocks and spaced apart from the limit blocks, a pressing member whose upper end movably passes through the top of the shell and whose lower end is located in the shell, a linkage member rotatably arranged in the shell and respectively abuts against the clamping member and the pressing member, an elastic member whose upper end is fixedly connected to the lower end of the pressing member, and an abutment plate fixedly connected to the lower end of the elastic member and capable of extending out of the bottom of the clamping member, the opposite sides of the two limit blocks are inclined and can fit together with the inclined surfaces of the clamping block, and after the clamping block is clamped between the two limit blocks, the clamping member and the abutment plate simultaneously press the clamping block.

[0014] By adopting the above technical solution, when the card block is pressed against the abutment plate, the abutment plate compresses the elastic part and enables the pressing part to simultaneously press the cross plate against the card block through the linkage part. After the abutment plate and the cross plate press the card block synchronously, the connection stability between the card assembly and the card block can be improved, and it is beneficial to the practical reliability of the panel body after installation.

[0018] Optionally, a first slot is formed on the opposite surfaces of the two connecting plates, and a second slot is formed on two opposite sides of a section of the pressing member located inside the housing;

[0019] The linkage part includes a rotating shaft rotatably arranged in the shell and a first clamping shaft and a second clamping shaft respectively fixed on opposite sides of the rotating shaft. The first clamping shaft and the second clamping shaft are spaced apart from the rotating shaft. The first clamping shaft is clamped in the first clamping slot, and the second clamping shaft is clamped in the second clamping slot. The clamping shaft can rotate in the clamping slot.

[0020] By adopting the above technical solution, the overall structure of the linkage member is simple, and a stable movable connection and linkage are formed between the clamping member and the pressing member.

[0021] Optionally, the pressing member includes a sliding column slidably arranged on the top of the shell and a limiting column fixedly connected to the upper end of the sliding column, and the lower end surface of the limiting column can abut against the top surface of the shell.

[0022] By adopting the above technical solution, the pressing member can be always stably arranged on the top of the shell through the limiting column.

[0023] Optionally, the abutment portion is machined on opposite sides to form arc-shaped segments that curve upward.

[0024] By adopting the above technical solution, when the clamping block contacts the abutting plate, the arc segment facilitates the abutting plate to slide onto the surface of the clamping block.

[0025] Optionally, a first clamping groove is provided on the top surface of the clamping block, and both the transverse plate and the abutting plate can be pressed tightly against the bottom of the first clamping groove.

[0026] By adopting the above technical solution, after the horizontal plate and the abutment plate slide into the first clamping groove, a limit is formed on the horizontal plate and the abutment plate, which can not only improve the connection stability of the top connecting component, but also improve the accuracy of alignment between the plug rod and the socket.

[0032] Optionally, the driving slot further includes a release segment whose upper end is connected to the lower end of the driving segment, the lower end of the release segment is connected to the plane edge, and the width of the release segment slot is respectively greater than the width of the driving segment slot and the length of the fixed block.

[0033] By adopting the above technical solution, after the fixing block is located in the release section, it is convenient to store and hide the plug-in rod.

[0034] In summary, this application has the following technical effects:

[0035] 1. After the top connecting assembly and the bottom connecting assembly are set, the card block is connected to the card assembly, and the card assembly is pressed against the card block. At this time, the plug rod is aligned with the socket at the bottom of the panel body. Then, the bottom connecting assembly is operated to insert the plug rod into the socket and lock the plug rod. The installation work of the top and bottom of the panel body can be quickly completed respectively. After releasing the bottom connecting assembly, the panel body can be pulled toward the outside of the building exterior wall to separate the panel body from the keel frame. This will not cause damage to the panel body and is also convenient for disassembly and subsequent replacement and maintenance of the panel body.

Each strip hole is provided with a group of top connecting components 3 and a group of bottom connecting components 4. The two groups of top connecting components 3 and the two groups of bottom connecting components 4 on two adjacent transverse ribs 11 are used to clamp a panel body 2.

[0049] Reference Figure 2 A notch is provided at the bottom of the horizontal keel 11 at the position corresponding to the strip hole. The top connection assembly 3 includes a clamping block 31 fixedly mounted on the back of the panel body 2 and a clamping assembly 32 disposed within the strip hole of the horizontal keel 11 and engaging with the clamping block 31. Two clamping blocks 31 are provided at intervals and can be simultaneously clamped to a pair of top connection assemblies 3. The side surface of the clamping block 31 is trapezoidal, and the length of the top surface is greater than the length of the ground. A first clamping groove 311 is provided in the middle of the top surface of the clamping block 31, with both ends connecting to the two side walls of the clamping block 31. Clamping blocks 312 are formed on both sides of the first clamping groove 311.

[0050] Combine Figure 3 and Figure 4 The clamping assembly 32 includes a shell 321, two limit blocks 322 integrally formed on opposite sides of the bottom of the shell 321, a clamping member 323 movably arranged inside the shell 321, a pressing member 324 movably arranged on the top of the shell 321 and extending into the shell 321, a linkage member 325 rotatably arranged in the shell 321 and rotatably clamped with the clamping member 323 and the pressing member 324 at both ends, an elastic member 326 vertically arranged and fixed at the upper end to the lower end surface of the pressing member 324 and located in the shell 321, and an abutment plate 327 fixed at the lower end of the elastic member 326 and capable of extending out of the shell 321.

[0051] The housing 321 includes two half shells assembled by two sets of bolts to form a receiving chamber 3211. The clamping member 323, the pressing member 324, the linkage member 325 and the elastic member 326 can all be located in the receiving chamber 3211. An opening is provided at the bottom of the housing 321 to communicate with the receiving chamber 3211. The clamping member 323 and the abutment plate 327 can extend out of the housing 321 through the opening. First limiting grooves 3212 with opposing notches are respectively provided on the inner walls at opposite ends of the receiving chamber 3211. The opposing side walls of the two limiting blocks 322 are machined into inclined surfaces, which are inclined relative to each other and face the receiving chamber 3211 of the housing 321. The inclined surfaces can fit together with the inclined surfaces of the outer walls of the clamping blocks 312.

[0052] Reference Figure 4 The clamping part 323 includes a horizontally arranged horizontal plate 3231, two connecting plates 3232 integrally formed on opposite sides of the horizontal plate 3231 and located on one side of the same plate surface, a limiting rib 3233 integrally formed on the opposite outer walls of the two connecting plates 3232 and with a length direction parallel to the length direction of the connecting plates 3232, and a limiting rod 3234 arranged vertically and with the lower end integrally formed on the upper surface of the connecting plate 3232. The thickness of the limiting rib 3233 is less than the width of the slot of the first limiting groove 3212 and the two limiting ribs 3233 can be respectively located in the two first limiting grooves 3212, and the limiting rib 3233 can move up and down in the first limiting groove 3212 along the length direction of the limiting rod 3234. The horizontal plate 3231 and the two connecting plates 3232 form a second engaging groove 3235. When the limiting rib 3233 is located within the first limiting groove 3212, the opening of the second engaging groove 3235 faces away from the opening of the housing 321. A limiting rod 3234 is slidably disposed through the top of the housing 321. When the limiting rib 3233 is located at the bottom of the first limiting groove 3212, the upper end of the limiting rod 3234 is located above the top of the housing 321.

[0053] Combine Figure 3 and Figure 4 The pressing part 324 includes a sliding column 3241 made of a square column and a limiting column 3242 integrally formed and set on the upper end surface of the sliding column 3241 and the edge of the end surface is located outside the end surface of the sliding column 3241. The sliding column 3241 is slidably set on the top of the shell 321 and is located between the two limiting rods 3234. The lower end of the sliding column 3241 is located in the notch of the second clamping groove 3235, and the two side walls of the sliding column 3241 are respectively facing the two connecting plates 3232.

[0054] Combine Figure 3 and Figure 4The linkage member 325 includes a rotating shaft 3251, whose ends rotate on the two half-shells and are located in the accommodating cavity 3211, as well as a first clamping shaft 3252 and a second clamping shaft 3253 integrally connected to the rotating shaft 3251. The first clamping shaft 3252 and the second clamping shaft 3253 are located on opposite sides of the rotating shaft 3251 and are spaced apart from the rotating shaft 3251. First engaging grooves 32321 are respectively defined on the opposing surfaces of the two connecting plates 3232, and second engaging grooves 32411 are respectively defined on the side walls of the sliding post 3241 facing the connecting plates 3232. The first clamping shaft 3252 is clamped in the first clamping grooves 32321, and the second clamping shaft 3253 is clamped in the second clamping grooves 32411. The clamping shafts are clamped in the clamping grooves and can rotate synchronously with the rotating shaft 3251.

[0055] Combine Figure 3 and Figure 4 In this embodiment, the elastic member 326 is a vertically arranged spring, the upper end of which is fixedly connected to the lower end surface of the sliding column 3241. The abutment plate 327 is arranged horizontally, and the upper plate surface is fixedly connected to the lower end of the spring. A rectangular hole is opened in the middle of the horizontal plate 3231 for the abutment plate 327 to extend out, and the abutment plate 327 is located below the horizontal plate 3231. Both edges of the abutment plate 327 near the length direction of the transverse keel 11 are bent, so that the edges of the abutment plate 327 are curved upward toward the interior of the accommodating cavity 3211 of the shell 321. When the clamping block 31 is engaged, it is easy to make way for the bottom of the first clamping groove 311, which facilitates the abutment plate 327 to slide into the first clamping groove 311. The limit block 322, the horizontal plate 3231, and the abutment plate 327 all extend out of the notch of the transverse keel 11 and are located within the rectangular hole area of the keel frame 1.

[0056] Combine Figure 5 and Figure 6 The bottom connecting assembly 4 includes a mounting seat 41 arranged in a strip hole, an operating rod 42 slidably penetrated on both sides of the mounting seat 41 in the horizontal direction and with its axial direction parallel to the length direction of the transverse keel 11, a plug-in rod 43 slidably penetrated on the top of the mounting seat 41 and slidably connected to the operating rod 42 at its lower end, a fixed shaft 44 arranged horizontally and one end of which is fixed at the center of one end face of the operating rod 42, and a locking nut 45 rotatably arranged on the fixed shaft 44 and spaced apart from the end face of the operating rod 42. The upper end of the plug-in rod 43 can be processed into a hemispherical end or a pointed end to reduce the end face area of the plug-in rod 43.

[0057] Reference Figure 2After the bottom connecting assembly 4 and the top connecting assembly 3 are simultaneously installed within the transverse keel 11, the locking nut 45 is positioned adjacent to the top connecting assembly 3, with the locking nut 45 spaced apart from the top connecting assembly 3 to provide operating space for the operating rod 42. A fixed shaft 44 is inserted through the end of the locking nut 45. The fixed shaft 44 may be provided with two fixing rings (not shown) located on opposite sides of the locking nut 45. Alternatively, a bearing may be mounted on the locking nut 45, with the inner ring of the bearing fixedly connected to the fixed shaft 44 and the outer ring of the bearing fixedly connected to the locking nut 45. Both of these methods allow the locking nut 45 to be rotatably mounted on the fixed shaft 44. The operating rod 42 is slidably inserted into the base and has an internal thread. The locking nut 45 is machined with an external thread that can be threadedly connected to the internal thread. Neither the internal thread nor the external thread is shown in the figure. When the upper end of the plug-in rod 43 is at its highest point, the locking nut 45 can be threadedly connected to the mounting seat 41.

[0058] Mounting base 41 comprises a horizontally arranged base plate 411, two vertically arranged mounting plates 412 fixedly attached to opposite sides of the upper surface of base plate 411, and a top plate 413 fixedly attached horizontally to the two mounting plates 412. Both mounting plates 412 are provided with a concentric circular hole for the operating rod 42, with internal threads machined into the inner wall of one of the holes. A first retaining bolt 4121 is threadedly connected to the outer wall of both mounting plates 412 on the same side. A second retaining bolt 4131 is threadedly connected to the outer wall of top plate 413.

[0059] The operating rod 42 is machined from a round rod. A second limiting groove 421 is defined on the outer circumference of the operating rod 42 along its axis. When the operating rod 42 is inserted into the circular hole, two first limiting bolts 4121 are capable of sliding within the second limiting groove 421. A flat surface is machined into the side of the operating rod 42 facing away from the second limiting groove 421. The flat surface is located in the middle of the operating rod 42 and spaced from both ends of the flat surface. A driving groove 422 is machined into the flat surface. The driving groove 422 includes an obliquely oriented driving section 4221 and a release section 4222 whose upper end is connected to the lower end of the driving section 4221. The upper end of the driving section 4221 is in contact with the inner wall of the operating rod 42 connected to the fixed shaft 44. The lower end of the release section 4222 is adjacent to the inner wall of the end of the operating rod 42 facing away from the fixed shaft 44 and is connected to the edge of the flat surface. The width of the notch of the release section 4222 is greater than the width of the notch of the driving section 4221 and greater than the length of the fixed block 432.

[0060] The plug rod 43 is made of a round rod and has a clearance groove 431 formed along the axis of the plug rod 43 and near its lower end. A fixing block 432 is formed between the clearance groove 431 and the lower end of the plug rod 43. A third limiting groove 433 is formed along the axis of the plug rod 43 on the outer wall of the plug rod 43 on the side away from the clearance groove 431, with the upper end connected to the upper end surface of the plug rod 43. Two insertion holes are spaced apart on the bottom side of the panel body 2. The upper end of the plug rod 43 is inserted into the insertion holes through the upper surface of the horizontal keel 11.

[0061] After the operating rod 42 and the plug rod 43 are both mounted on the mounting base 41, the clearance slot 431 can make way for the driving slot 422, thereby allowing the plug rod 43 to be raised or lowered. The fixing block 432 is arranged at an angle and adapted to the driving slot 422. When the fixing block 432 is located in the driving section 4221, sliding the operating rod 42 left or right can cause the plug rod 43 to be raised or lowered. When the fixing block 432 is located in the release section 4222, the fixing block 432 is located on the bottom plate 411, at which time the driving relationship between the operating rod 42 and the plug rod 43 is released. The second limiting bolt 4131 is located in the third limiting groove 433 to limit the insertion rod 43, so that the insertion rod 43 can always remain in a vertical position. When the fixing block 432 is located at the inclined upper end of the driving section 4221, the insertion rod 43 is inserted into the panel body 2. When the fixing block 432 is located in the release section 4222, the upper end of the insertion rod 43 is no higher than the upper surface of the horizontal keel 11, thereby facilitating the removal and placement of the panel body 2 from the rectangular hole area of the keel frame 1. After the insertion rod 43 is inserted into the insertion hole, the locking nut 45 is screwed into the mounting plate 412 to lock the position of the operating rod 42.

[0062] When installing the panel body 2, place the panel body 2 into the rectangular hole area corresponding to the keel frame 1, so that the two clamping blocks 31 can be clamped into the clamping assembly 32, and the inclined surface of the clamping block 312 is aligned with the inclined surface of the limit block 322. When the clamping block 31 enters the interior of the clamping assembly 32, the bottom of the first clamping groove 311 abuts against the abutment plate 327 and pushes the abutment plate 327 upward. At the same time, the elastic member 326 is compressed and pushes the pressing member 324 upward. The pressing member 324 makes the lower surface of the horizontal plate 3231 and the abutment plate 327 simultaneously press against the bottom of the first clamping groove 311 through the linkage member 325. At this time, the top connecting assembly 3 completes the installation work on the top of the panel body 2. Then the staff uses their hands to reach deep into the strip hole of the horizontal keel 11 and push the operating rod 42 horizontally, driving the plug rod 43 to be fully inserted into the jack, and then screwing the locking nut 45 to complete the installation work on the bottom of the panel body 2.

[0063] When the panel body 2 needs to be disassembled, screw the locking nut 45 to release the restriction of the operating rod 42, pull the operating rod 42 so that the fixing block 432 is located in the release section 4222, and then directly pull the panel body 2 out in the direction of the keel frame 1 away from the exterior wall of the building. The disassembly of the panel body 2 can be completed quickly without causing damage to the panel body 2.

[0064] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
