Description

Technical Field

[0001] This application relates to the technical field of curtain wall installation, and in particular to a curtain wall fixing device and a curtain wall construction method. Background Technology

[0002] A curtain wall is a non-load-bearing exterior wall cladding for a building. It is hung up like a curtain, hence the name "curtain wall". It is a lightweight wall structure with decorative effect commonly used in modern large and high-rise buildings. It consists of a curtain wall body and a keel frame system. It can have a certain displacement capacity relative to the main structure or a certain deformation capacity itself. It is an exterior building envelope or decorative structure that does not bear the load of the main structure.

[0003] Currently, when installing curtain walls, it is necessary to prefabricate the installation components inside the concrete wall first, and then connect and fix the curtain wall to the prefabricated components with bolts.

[0004] Regarding the aforementioned technologies, the inventors believe that existing curtain wall installations require a large amount of manual labor, which causes inconvenience to the workers installing the curtain walls. Summary of the Invention

[0005] To improve the convenience of curtain wall installation, this application provides a curtain wall fixing device and a curtain wall construction method.

[0006] Firstly, this application provides a curtain wall fixing device, which adopts the following technical solution:

[0007] A curtain wall fixing device includes a curtain wall body and a frame. The frame includes a back plate and a fixing frame. The fixing frame is fixedly connected to and communicates with the back plate. A fixing rod is fixedly provided on the side of the curtain wall body facing the back plate. The back plate has a fixing hole adapted to be inserted into the fixing rod. The fixing frame has a snap-fit ​​plate inside for snapping and fixing with the curtain wall body. The side wall of the curtain wall body has a snap-fit ​​groove for snapping and fixing with the snap-fit ​​plate. A compression spring is fixedly connected between the snap-fit ​​plate and the fixing frame. The compression spring is in a compressed state. An insertion assembly for fixing the snap-fit ​​plate is provided between the fixing hole and the snap-fit ​​plate.

[0008] By adopting the above technical solution, when workers install the curtain wall, they only need to push the curtain wall closer to the back panel and insert the fixing rod into the fixing hole. When the slot is aligned with the snap-fit ​​plate, the fixing rod drives the plug-in assembly to move, causing the plug-in assembly to unlock the snap-fit ​​plate. The compression spring releases its elasticity, causing the snap-fit ​​plate to snap into the slot, thus achieving the fixation between the curtain wall and the keel frame. This operation is simple and convenient, thus providing convenience for workers when installing the curtain wall.

[0009] Optionally, the plug-in assembly includes a trigger rod, a plug-in rod, and a hinge rod. One end of the trigger rod extends into the fixing hole, and a connecting spring is fixedly connected between the other end of the trigger rod and the inner wall of the fixing frame. One end of the plug-in rod is plugged and fixed to the snap-fit ​​plate. One end of the hinge rod is hinged to the end of the plug-in rod away from the snap-fit ​​plate, and the other end of the hinge rod is hinged to the side wall of the trigger rod.

[0010] By adopting the above technical solution, when the fixing rod is inserted into the fixing hole, the fixing rod pushes the trigger rod to move away from the fixing hole. The fixing rod compresses the connecting spring, and the fixing rod drives the plug rod to be pulled out from the snap-fit ​​plate through the hinge rod, thereby unlocking the snap-fit ​​plate.

[0011] Optionally, the back plate has a magnet fixed in the fixing hole, and the magnet can magnetically attract the end of the fixing rod.

[0012] By adopting the above technical solution, when the fixing rod is inserted into the fixing hole, the magnet attracts the fixing rod to move closer, which enables the curtain wall to automatically move closer to the back panel and fit tightly, and enables the snap-fit ​​plate to align with the snap-fit ​​slot, which further facilitates the installation of the curtain wall by the staff.

[0013] Optionally, the curtain wall body is internally equipped with an active bevel gear, a rotating rod, and a push rod. The active bevel gear is located at the center of the curtain wall body and is rotatably connected to it. The rotating rod is located along the center of the curtain wall body towards the top corner and is rotatably connected to it. A driven bevel gear is fixedly mounted on one end of the rotating rod near the active bevel gear, and the driven bevel gear meshes with the active bevel gear. The circumferential sidewall of the rotating rod is machined with a threaded structure. An unlocking block is threadedly connected to the rotating rod. The unlocking block moves along the length of the rotating rod. A push plate is provided on the side of the slot away from the edge of the curtain wall body. The push plate is slidably connected to the curtain wall body in the direction of movement toward the slot. The push rod is located between the push plate and the unlocking block. One end of the push rod is fixedly connected to the push plate, and the other end of the push rod abuts against the unlocking block. When the unlocking block moves away from the active bevel gear, the unlocking block pushes the push rod to move, and the push rod then drives the push plate to move into the slot.

[0014] By adopting the above technical solution, when it is necessary to disassemble the curtain wall, simply rotate the active bevel gear, which drives the driven bevel gear to rotate, and the driven bevel gear drives the rotating rod to rotate. The unlocking block moves along the length of the rotating rod. Through the contact between the unlocking block and the push rod, the push rod drives the push plate to move into the snap-fit ​​groove and pushes the snap-fit ​​plate back into the fixing frame, thereby releasing the fixing between the fixing frame and the curtain wall.

[0015] Optionally, the push rod sleeve is provided with a movable plate, a fixed plate and a return spring. The push rod is fixedly connected to the movable plate and slidably connected to the fixed plate. The fixed plate is fixedly connected to the curtain wall body, and the two ends of the return spring are fixedly connected to the movable plate and the fixed plate respectively.

[0016] By adopting the above technical solution, when the curtain wall is unlocked, the unlocking block drives the push rod to move. At this time, the reset spring is in a compressed state. When the unlocking block moves away from the curtain wall, the reset spring releases its elastic force, driving the moving plate and the push rod back to their original positions.

[0017] Optionally, the fixing rod is provided with a threaded sleeve and a threaded rod. The threaded sleeve and the threaded rod are threadedly connected. The threaded sleeve is rotatably connected to the fixing rod. The end of the fixing rod away from the curtain wall is connected to its own interior. The threaded rod moves along the length of the fixing rod and can extend out from the interior of the fixing rod.

[0018] By adopting the above technical solution, rotating the threaded sleeve causes the threaded rod to extend from the inside of the threaded sleeve. Continuing to rotate the threaded sleeve causes the threaded rod to extend from the inside of the fixed rod, generating a reaction force that drives the curtain wall away from the back panel, further facilitating the disassembly of the curtain wall by workers.

[0019] Optionally, the end of the rotating rod opposite to the driven bevel gear is fixedly connected to a first bevel gear, and the end of the threaded sleeve opposite to the threaded rod is fixedly connected to a second bevel gear, with the first bevel gear meshing with the second bevel gear.

[0020] By adopting the above technical solution, when the worker rotates the active bevel gear, the active bevel gear can drive the rotating rod to rotate. The rotating rod can drive the threaded sleeve to rotate through the meshing of the first bevel gear and the second bevel gear. Thus, through the above structure, when the worker rotates the active bevel gear, the threaded sleeve can be driven to rotate together, which facilitates the worker's disassembly work.

[0021] Optionally, a handwheel is fixed to one side of the drive bevel gear.

[0022] By adopting the above technical solution, the operator can drive the drive bevel gear to rotate by turning the handwheel, which provides convenience for the operator to rotate the drive bevel gear.

[0023] Optionally, a panel is provided on the side of the handwheel away from the driving bevel gear. The panel is flush with the surface of the curtain wall. A plug rod is fixed on the side of the panel facing the handwheel. The handwheel has a plug hole. The plug rod and the plug hole are interference fit.

[0024] By adopting the above technical solution, the panel serves to shield the interior of the curtain wall, protect the internal structure of the curtain wall, and improve the aesthetics of the curtain wall.

[0025] Secondly, this application provides a curtain wall fixing device and a curtain wall construction method, adopting the following technical solution:

[0026] A curtain wall construction method includes the following steps:

[0027] S1. When installing the curtain wall, push the curtain wall closer to the back panel so that the fixing rod is inserted into the fixing hole;

[0028] S2. The fixing rod pushes the trigger rod out of the fixing hole, and the trigger rod drives the plug rod to be pulled out of the snap plate through the hinge rod;

[0029] S3. The compression spring will spring the snap-fit ​​plate into the slot;

[0030] S4. When unlocking the curtain wall, turn the handwheel to move the unlocking block. The unlocking block drives the push rod and push plate to move and push the locking plate back into the fixed frame.

[0031] S5. When the handwheel is turned, the threaded sleeve is rotated, causing the threaded rod to extend from the inside of the fixed rod, forming a reaction force that moves the curtain wall away from the back panel.

[0032] By adopting the above technical solution, when installing the curtain wall, simply move the curtain wall towards the back panel and insert the fixing rod into the fixing hole. After the fixing rod is fully inserted into the fixing hole, the compression spring can push the snap-fit ​​plate into the slot, thereby realizing the installation and fixing of the curtain wall. When it is necessary to disassemble the curtain wall, simply turn the handwheel, and the push plate will push the snap-fit ​​plate back into the fixing frame. The threaded rod extends from the inside of the fixing sleeve to form a reaction force, pushing the curtain wall away from the back panel, thereby disassembling the curtain wall. The above structure achieves the effect of easy installation and disassembly of the curtain wall.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. Simply insert the fixing rod into the fixing hole to automatically complete the installation of the curtain wall;

[0035] 2. By turning the handwheel, the push plate can be pushed back into the fixing frame, thereby unlocking the curtain wall and the fixing frame.

[0036] 3. When the handwheel is turned, the threaded rod extends out from the fixed sleeve to generate a reaction force, which moves the curtain wall away from the back panel, thus facilitating the disassembly of the curtain wall by the staff. Attached Figure Description

[0043] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0044] This application discloses a curtain wall fixing device.

[0045] refer to Figure 1 A curtain wall fixing device includes a curtain wall body 1 and a frame 2. The frame 2 includes a back panel 21 and a fixing frame 22. The fixing frame 22 is fixed around the back panel 21. When the curtain wall body 1 and the frame 2 are installed and fixed, the back of the curtain wall body 1 abuts against the surface of the back panel 21, and the side walls around the curtain wall body 1 abut against the side walls of the fixing frame 22.

[0046] Reference Figure 2 and Figure 3Fixing rods 11 are fixed at the four corners of the curtain wall 1 facing the back panel 21. Fixing holes 211 are provided at the four corners of the back panel 21 to be inserted into the fixing rods 11. Magnets 2111 that can be magnetically attracted to the fixing rods 11 are fixed in the fixing holes 211. The side walls of the curtain wall 1 are provided with slots 12 along their own edge length. The inside of the fixing frame 22 is provided with a snap-fit ​​plate 221 that is adapted to snap-fit ​​into the slot 12 along its own edge length. A compression spring 222 is fixedly connected between the side of the snap-fit ​​plate 221 away from the curtain wall 1 and the inner wall of the fixing frame 22. An insertion component 3 for fixing the snap-fit ​​plate 221 is provided between the fixing hole 211 and the snap-fit ​​plate 221. In this embodiment, each snap-fit ​​plate 221 corresponds to two sets of insertion components 3, and each set of insertion components 3 is located at both ends of the snap-fit ​​plate 221.

[0047] The plug-in assembly 3 includes a trigger rod 31, a plug-in rod 32, and a hinge rod 33. The trigger rod 31 is located between the back plate 21 and the fixing frame 22, and one end of the trigger rod 31 is inserted into the fixing hole 211. The other end of the trigger rod 31 is fixedly connected to the inner wall of the fixing frame 22 by a connecting spring 311. One end of the plug-in rod 32 is inserted into the side wall of the snap-fit ​​plate 221. One end of the hinge rod 33 is hinged to the end of the plug-in rod 32 away from the snap-fit ​​plate 221, and the other end of the hinge rod 33 is hinged to the side wall of the trigger rod 31.

[0048] When installing the curtain wall 1, move the curtain wall 1 closer to the back panel 21 and insert the fixing rod 11 into the fixing hole 211. The magnet 2111 attracts the fixing rod 11, which automatically moves the curtain wall 1 towards the back panel 21 until the curtain wall 1 and the back panel 21 come into contact. At this time, the fixing rod 11 is fully inserted into the fixing hole 211, and the snap-fit ​​plate 221 is aligned with the snap-fit ​​slot 12. The fixing rod 11 pushes the end of the trigger rod 31 out of the fixing hole 211. During the movement, the trigger rod 31 drives the insertion rod 91 to be pulled out of the snap-fit ​​plate 221 through the hinge rod 33, thereby unlocking the snap-fit ​​plate 221. The compression spring 222 releases its elasticity and pushes the snap-fit ​​plate 221 into the space between the fixing frame 22 and the snap-fit ​​slot 12, thereby realizing the installation and fixation between the curtain wall 1 and the keel frame 2. This operation is simple and convenient, and achieves the effect of easy installation of the curtain wall 1.

[0049] Reference Figure 4 and Figure 5A drive bevel gear 4 is rotatably connected to the middle of the curtain wall 1. Rotating rods 5 are provided along the middle of the curtain wall 1 to its four corners, rotatably connected to the curtain wall 1. One end of each rotating rod 5 is fixedly connected to a driven bevel gear 51, which meshes with the drive bevel gear 4. The circumferential sidewall of the rotating rod 5 is threaded, and an unlocking block 52 is threadedly connected to it. In this embodiment, the unlocking block 52 has a trapezoidal cross-section, and both sides of the unlocking block 52 gradually slope towards the rotating rod 5 from the center of the curtain wall 1 to its apex. A push plate 6 is provided on the side of the slot 12 away from the fixing frame 22. A push rod 61 is provided between the push plate 6 and the unlocking block 52, one end of which is fixedly connected to the push plate 6, and the other end abuts against the inclined surface of the unlocking block 52. A handwheel 41 is provided on one side of the drive bevel gear 4, and is fixedly connected to the drive bevel gear 4.

[0050] Reference Figure 4 and Figure 5 When the staff needs to disassemble the curtain wall 1, they only need to turn the handwheel 41 to drive the active bevel gear 4 to rotate. The active bevel gear 4 drives the rotating rod 5 to rotate through the meshing with the driven bevel gear 51. The rotating rod 5 is threadedly connected to the unlocking block 52. Through the restriction of the unlocking block 52 by the curtain wall 1, the unlocking block 52 moves along the length direction of the rotating rod 5, pushing the push rod 61 to move. The push rod 61 drives the push plate 6 to push the snap plate 221 back into the fixed frame 22, thereby realizing the unlocking between the curtain wall 1 and the keel frame 2.

[0051] Reference Figure 4 and Figure 5 A push rod 61 has a movable plate 611, a fixed plate 612, and a return spring 613 passing through it along its length. The push rod 61 is fixedly connected to the movable plate 611 and slidably connected to the fixed plate 612. The fixed plate 612 is fixedly connected to the inner wall of the curtain wall 1. The two ends of the return spring 613 are fixedly connected to the movable plate 611 and the fixed plate 612, respectively. When the unlocking block 52 moves the push rod 61, the return spring 613 is in a compressed state. When the unlocking block 52 moves away from the push rod 61, the return spring 613 can release its elastic force to drive the movable plate 611 and the push rod 61 back to their original positions.

[0052] Reference Figure 3Each fixed rod 11 is provided with a threaded sleeve 7 and a threaded rod 8. The threaded sleeve 7 is rotatably connected to the fixed rod 11, and the threaded sleeve 7 is threadedly connected to the threaded rod 8. The end of the fixed rod 11 away from the curtain wall 1 is open and passes through its own interior. The threaded rod 8 is provided with a sliding groove 81 along its own length direction. The inner wall of the fixed rod 11 is fixed with a slider 111 that is slidably adapted to the sliding groove 81. The threaded rod 8 can extend from the end of the fixed rod 11 away from the curtain wall 1. A first bevel gear 53 is fixed at one end of the rotating rod 5 near the threaded sleeve 7, and a second bevel gear 71 is fixed at the threaded sleeve 7. The first bevel gear 53 and the second bevel gear 71 mesh with each other. The snap-fit ​​plate 221 is set as an inclined surface on the side facing the back plate 21. When the operator turns the handwheel 41, the rotating rod 5 rotates. The rotating rod 5 drives the threaded sleeve 7 to rotate through the meshing of the first bevel gear 53 and the second bevel gear 71. Under the action of the threaded connection with the threaded sleeve 7, and through the sliding of the slider 111 in the slide groove 81, the threaded rod 8 extends out from the inside of the fixed rod 11, forming a reaction force, pushing the curtain wall 1 away from the back plate 21. This can achieve the effect of making the fixed rod 11 get away from the attraction of the magnet 2111, which provides convenience for the operator to disassemble the curtain wall 1.

[0053] Reference Figure 4 The handwheel 41 is located on the side panel 9 opposite to the first bevel gear 53. The panel 9 is flush with the surface of the curtain wall 1. A plug rod 91 is fixed on the side of the panel 9 facing the handwheel 41. The handwheel 41 has a plug hole 411. The plug rod 91 and the plug hole 411 are interference-fitted. The panel 9 serves to shield the interior of the curtain wall 1, thus protecting the interior of the curtain wall 1 and improving its aesthetics.

[0054] The implementation principle of a curtain wall construction method according to an embodiment of this application is as follows: including the following steps:

[0055] Reference Figure 2 and Figure 3 S1. When installing the curtain wall 1, push the curtain wall 1 closer to the back panel 21 so that the fixing rod 11 is inserted into the fixing hole 211. The magnetic attraction of the magnet 2111 can automatically drive the fixing rod 11 to be fully inserted into the fixing hole 211, and make the curtain wall 1 fit with the back panel 21, and the snap plate 221 is aligned with the snap groove 12.

[0056] S2, the fixing rod 11 pushes the trigger rod 31 out of the fixing hole 211, and the trigger rod 31 drives the plug rod 32 to be pulled out of the snap plate 221 through the hinge rod 33;

[0057] S3. The compression spring 222 pushes the snap plate 221 into the snap slot 12, thereby completing the installation of the curtain wall 1.

[0058] Reference Figure 4 and Figure 5S4. When disassembling the curtain wall 1, turn the handwheel 41 to move the unlocking block 52. The unlocking block 52 drives the push rod 61 to move. The push rod 61 drives the push plate 6 to gradually move into the slot 12. The push plate 6 pushes the snap plate 221 back into the fixing frame 22.

[0059] Reference Figure 3 and Figure 4 When the handwheel 41 is turned, the rotating rod 5 rotates. The rotating rod 5 can drive the threaded sleeve 7 to rotate through the meshing of the first bevel gear 53 and the second bevel gear 71, so that the threaded rod 8 extends out from the inside of the fixed rod 11 and abuts against the magnet 2111, forming a reaction force, pushing the curtain wall 1 away from the back panel 21, which makes it easier for the staff to disassemble the curtain wall 1.
