Technical Field

[0001] This application relates to the technical field of building curtain walls, and in particular to a curtain wall connector and a curtain wall construction method based on the connector. Background Art

[0002] With the continuous acceleration of the social urbanization process, the number of high-rise buildings is increasing day by day, and the requirements for the safety and aesthetics of curtain wall systems are also constantly improving.

[0003] However, the curtain wall panels in traditional curtain wall systems are generally fixedly installed on the building wall by bolts or welding. Once installed, it is very difficult to adjust the position of the curtain wall panels again, which needs to be improved. Summary of the Invention

[0004] In order to solve the problem that it is difficult to adjust the position of the curtain wall panel after it is installed in place, this application provides a curtain wall connector and a curtain wall construction method based on the connector.

[0005] In a first aspect, a curtain wall connector provided by this application adopts the following technical solution: A curtain wall connector includes a base plate fixed on a building wall, a mounting block rotatably arranged on the base plate, a positioning plate detachably connected to a curtain wall panel, and a connecting block fixed on the side of the positioning plate facing the base plate. A connecting groove is formed on the mounting block for the connecting block to slide into. A stop assembly is arranged on the base plate for locking or unlocking the mounting block, a locking assembly is arranged on the mounting block for preventing the connecting block from moving out of the connecting groove, and an unlocking assembly is arranged on the positioning plate for unlocking the connecting block in the connecting groove.

[0006] By adopting the above technical solution, when the curtain wall panel is installed on the building wall, the connecting block is inserted into the connecting groove, and the locking assembly can prevent the connecting block from moving out of the connecting groove, so as to realize the relative fixation of the curtain wall panel and the building wall. After the curtain wall panel is installed in place, if its position needs to be adjusted again, the curtain wall panel can be first removed from the positioning plate, and then the locking of the connecting block can be released through the unlocking assembly. At this time, the connecting block is no longer restricted and can move out of the connecting groove. Then, the mounting block is unlocked through the stop assembly, and then the mounting block is rotated to the required position. Then, the stop assembly is operated to lock the mounting block, and the curtain wall panel is reconnected to the positioning plate. Finally, the connecting block is extended into the connecting groove, and the connecting block is locked through the locking assembly. In this way, the operator can rotate the mounting block to adjust the position of the connecting groove, so as to change the installation angle of the subsequent curtain wall panel to meet different decoration requirements, and it has strong practicability.

[0007] Optionally, a fixing groove is provided on the groove wall of the connecting groove, and the locking assembly includes a locking block slidably arranged in the fixing groove, and a locking spring for driving the locking block to extend out of the fixing groove; a locking groove is provided on the connecting block for the locking block to extend into, and the direction in which the locking block extends into the locking groove is perpendicular to the direction in which the connecting block extends into the connecting groove, and a guide bevel is provided on the end of the locking block close to the opening of the connecting groove, and the guide bevel can guide the locking block toward the interior of the fixing groove when the connecting block extends into the connecting groove.

[0008] By adopting the above technical solution, when installing the curtain wall panel, in the process of the connecting block extending into the connecting groove, the guiding inclined surface will first contact the connecting block, and under the pressure of the connecting block, the locking block will be driven to move into the fixed groove. At this time, the locking spring is in a compressed state and generates elastic force. When the connecting block moves to align the locking groove with the locking block, the locking block will automatically extend into the locking groove under the elastic force of the locking spring, thereby locking the connecting block. The structure is simple and the locking effect is good. The above locking method can be automatically performed when the connecting block extends into the connecting groove, without the operator having to manually operate the locking assembly, which is conducive to simplifying the installation process of the curtain wall panel and improving the installation efficiency.

[0009] Optionally, the unlocking assembly includes an unlocking plate slidably arranged in the positioning plate, and a push rod arranged on the side of the unlocking plate facing the connecting block, the connecting block is provided with a through hole interconnected with the locking groove, the push rod is slidably arranged in the through hole and can push the locking block out of the locking groove.

[0010] By adopting the above technical solution, when unlocking the connection block, after removing the curtain wall panel, it is only necessary to press the unlocking plate to the side close to the connection block so that the push rod pushes the locking block out of the locking groove. The structure is simple and the operation is convenient.

[0011] Optionally, a side wall of the positioning plate away from the connecting block is provided with a clearance groove, the unlocking plate is slidably arranged in the clearance groove, and the unlocking assembly also includes an unlocking spring abutting between the unlocking plate and the wall of the clearance groove; when the unlocking spring is in a natural state, the push rod moves out of the locking groove.

[0012] By adopting the above technical solution, the unlocking spring can drive the push rod to remain in the state of being moved out of the locking groove, and will not affect the locking block from extending into the locking groove.

[0013] Optionally, the stop assembly includes a stop block slidably disposed on a base plate, a stop spring for driving the stop block to move toward a mounting block, a stop gear is fixed on the mounting block, and a plurality of stop grooves for the stop block to extend into are continuously distributed on the circumferential side wall of the stop gear.

[0014] By adopting the above technical solution, after the installation block rotates into place, the stop block will extend into the adjacent stop groove under the action of the stop spring, thereby locking the installation block, with good locking effect and high stability of the installation block.

[0015] Optionally, the stop block includes a movable part and a stop part fixed on the side of the movable part away from the substrate. An activity groove slidably matched with the movable part is formed on the substrate. The activity grooves and the cross sections of the movable parts are both trapezoidal, and the stop spring is abutted and arranged between the movable part and the groove wall of the activity groove.

[0016] By adopting the above technical solution, the movable part is slidably matched with the activity groove, so that the stop block can only move in a specified direction, which is beneficial to the alignment of the stop block with the adjacent stop groove. In addition, the cross sections of the movable part and the activity groove are both trapezoidal, making it difficult for the movable part to escape from the activity groove, and the stop block will not separate from the substrate, and the integrity of the curtain wall connecting piece is good.

[0017] Optionally, two sets of the stop assemblies are provided and are respectively arranged on both sides of the installation block. A linkage assembly for driving the stop blocks in the two stop assemblies to move synchronously is arranged on the substrate.

[0018] By adopting the above technical solution, multiple sets of stop assemblies are provided, so that the installation block can be locked at multiple places and has high stability. The linkage assembly can drive the two stop blocks to move synchronously, which can not only improve the locking or unlocking efficiency of the installation block, but also when the installation block needs to be rotated, there is no need to manually synchronously control the positions of the two stop blocks, and the operation is convenient.

[0019] Optionally, the linkage assembly includes two extension blocks oppositely arranged on the substrate, a bidirectional lead screw rotatably arranged between the two extension blocks, and linkage rods respectively threadedly connected to different threaded sections of the bidirectional lead screw. Each linkage rod is fixedly connected to a different stop block.

[0020] By adopting the above technical solution, when the bidirectional lead screw rotates, the two linkage rods will move synchronously towards or away from each other, and then drive the stop blocks connected thereto to move synchronously, so that the two stop blocks synchronously move into or out of the adjacent stop grooves, with simple structure and high locking or unlocking efficiency of the installation block.

[0021] In a second aspect, the present application provides a curtain wall construction method based on a connecting piece, including the following steps: S1. First, fixedly install the substrate on the building wall, then control the installation block to rotate relative to the substrate. After the installation block rotates to the required position, lock the installation block through the stop assembly; S2. First, fixedly install the positioning plate on the curtain wall panel, then insert the connecting block into the connecting groove, and lock the connecting block through the locking assembly to complete the installation of a single curtain wall panel; S3. Repeat the above steps until the installation of all curtain wall panels is completed.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: When installing the curtain wall panel, the operator can rotate the installation block relative to the base plate, causing the position of the connecting groove to change, thereby changing the installation angle of the subsequent curtain wall panel to meet different decoration requirements, with strong practicability. After the installation block rotates in place, rotate the bidirectional lead screw, causing the two linkage rods to move towards each other, and the two stop blocks will synchronously move into the adjacent stop grooves, thereby locking the installation block; if it is necessary to unlock the installation block, just rotate the bidirectional lead screw in the reverse direction, and the locking and unlocking efficiency of the installation block is high. During the process of the connecting block extending into the connecting groove, the locking block will automatically extend into the locking groove under the action of the locking spring, thereby realizing the locking of the connecting block; when unlocking the connecting block, just press the unlocking plate to make the push rod push the locking block away from the locking groove, and the operation is simple.

[0030] The following will further elaborate on this application Figures 1-6 with reference to the attached drawings.

[0031] The embodiment of this application discloses a curtain wall connector and a curtain wall construction method based on the connector.

[0032] Referring to Figure 1 and Figure 2 , the curtain wall connector includes a substrate 1, a mounting block 2 rotatably arranged on the substrate 1, a positioning plate 3, and a connecting block 4 fixedly arranged on the positioning plate 3 (see Figure 3 ). During use, the substrate 1 is fixedly installed on the building wall, the positioning plate 3 is detachably connected to the curtain wall panel, and the connecting block 4 is located on the side of the positioning plate 3 facing the substrate 1. Specifically, in this embodiment, the connection methods between the substrate 1 and the building wall, and between the positioning plate 3 and the curtain wall panel are preferably bolt connections; in other implementation modes, the substrate 1 and the building wall can also be connected by welding or other methods, and the positioning plate 3 and the curtain wall panel can also be connected by snap connection or other methods. Any method that can achieve relative fixation between the two is acceptable.

[0033] Referring to Figure 3 and Figure 4 , a connecting groove 21 is formed on the side wall of the mounting block 2 away from the substrate 1. The connecting groove 21 is used for the connecting block 4 to slide and extend into, so as to realize the plug-in installation of the curtain wall panel. Preferably, the cross-sections of the above-mentioned connecting block 4 and the connecting groove 21 are square, so that the connecting block 4 is not easy to rotate in the connecting groove 21, and the stability of the curtain wall panel is high.

[0034] Referring to Figure 3 and Figure 4, in order to prevent the connecting block 4 from moving out of the connecting groove 21, a locking component 5 is provided on the mounting block 2 to limit the position of the connecting block 4. Fixed grooves 22 are respectively formed on the two opposite side walls of the connecting groove 21. Two groups of locking components 5 are provided and are respectively arranged in different fixed grooves 22. Each locking component 5 includes a locking block 51 slidably arranged in the fixed groove 22 and a locking spring 52 for driving the locking block 51 to move out of the fixed groove 22. One end of the locking spring 52 is connected to the locking block 51, and the other end is connected to the groove wall of the fixed groove 22 away from the connecting groove 21. And the telescopic direction of the locking spring 52 is perpendicular to the direction in which the connecting block 4 extends into the connecting groove 21.

[0035] Refer to Figure 3 , Figure 5 , locking grooves 41 are respectively formed on the two opposite side walls of the connecting block 4, and a guiding inclined surface 42 is provided at one end of the locking block 51 close to the opening of the connecting groove 21. When the connecting block 4 extends into the connecting groove 21, the guiding inclined surface 42 will contact the connecting block 4 and guide the locking block 51 into the interior of the fixed groove 22. At this time, the locking spring 52 is compressed and generates elastic force; after the connecting block 4 moves to align the locking groove 41 with the locking block 51, the locking block 51 will move along the telescopic direction of the locking spring 52 under the action of the locking spring 52 and extend into the locking groove 41 to lock the connecting block 4.

[0036] Refer to Figure 3 , Figure 4 , in order to release the lock of the connecting block 4 in the connecting groove 21 to facilitate the removal of the curtain wall panel, an unlocking component 6 is provided on the positioning plate 3. The unlocking component 6 includes an unlocking plate 61, two push rods 62 arranged on the side of the unlocking plate 61 facing the connecting block 4, and a plurality of unlocking springs 63 abutted between the unlocking plate 61 and the positioning plate 3. A relief groove 31 is formed on the side wall of the positioning plate 3 away from the connecting block 4, and the unlocking plate 61 is slidably arranged in the relief groove 31. One end of the unlocking spring 63 is connected to the unlocking plate 61, and the other end is connected to the groove wall of the relief groove 31 away from its own opening.

[0037] Refer to Figure 3 , Figure 5, the connection block 4 is provided with two through holes 43 respectively connected to different locking grooves 41, and the groove wall of the giving way groove 31 is provided with two through holes 32 respectively connected to different through holes 43, one of which is slidably inserted into the through hole 43 and the through hole 32 connected thereto, and the other is slidably inserted into the other through hole 43 and the through hole 32 connected thereto. When the unlocking spring 63 is in a natural state, the push rod 62 is located outside the locking groove 41, and will not affect the locking block 51 extending into the locking groove 41 to lock the connection block 4; when the connection block 4 needs to be unlocked, it is only necessary to press the unlocking plate 61, so that the two push rods 62 can be synchronously moved into the adjacent locking grooves 41, and then the locking block 51 can be pushed out of the locking groove 41, which is easy to operate.

[0038] Reference Figure 6 A stopper assembly 7 is provided on one side of the base plate 1 facing the mounting block 2. The stopper assembly 7 can be used to lock or unlock the mounting block 2, so that the mounting block 2 is fixed at a desired position. In this embodiment, the stopper assembly 7 is preferably two groups and is disposed on both sides of the mounting block 2. In other embodiments, the stopper assembly 7 can also be designed to have other numbers according to requirements.

[0039] Reference Figure 6 The stop assembly 7 includes a stop block 71 and a stop spring 72 for driving the stop block 71 to move toward the mounting block 2. The stop block 71 includes a movable portion 711 and a stop portion 712 fixed to the side of the movable portion 711 away from the substrate 1. Two movable grooves 11 are provided on the side wall of the substrate 1 close to the mounting block 2. The movable portions 711 in each stop block 71 are respectively slidably arranged in different movable grooves 11, and the cross-sections of the movable grooves 11 and the movable portions 711 are both trapezoidal. The stop spring 72 is abutted between the movable portion 711 and the groove wall of the movable groove 11 away from the mounting block 2. A stop gear 23 is fixed to the circumferential side wall of the mounting block 2. A plurality of stop grooves 231 are continuously distributed on the circumferential side wall of the stop gear 23. The stop grooves 231 are adapted to the shape of the stop portion 712 and can be slid into by the stop portion 712, so as to achieve the locking of the mounting block 2.

[0040] Reference Figure 6, in order to improve the stability of the mounting block 2 and quickly unlock the mounting block 2, a linkage assembly 8 is provided on the base plate 1 to drive the locking blocks 71 in the two sets of locking assemblies 7 to move synchronously. The linkage assembly 8 includes two extension blocks 81 oppositely arranged on the base plate 1, a bidirectional lead screw 82 rotatably arranged between the two extension blocks 81, and linkage rods 83 respectively threadedly connected to different threaded segments of the bidirectional lead screw 82. The extension blocks 81 are fixedly connected to the base plate 1, and each linkage rod 83 is fixedly connected to a different locking block 71. When the bidirectional lead screw 82 rotates, the two linkage rods 83 will move synchronously towards or away from each other, thereby causing the two locking blocks 71 to synchronously move into or out of the adjacent locking grooves 231, so as to achieve quick locking or unlocking of the mounting block 2, with a simple structure and convenient operation. It should be noted that, for the convenience of rotating the bidirectional lead screw 82, a handle 84 is provided at the end of the bidirectional lead screw 82 in this embodiment. In other embodiments, a power component such as a servo motor can also be additionally provided to drive the rotation of the bidirectional lead screw 82. In addition, in order to prevent the linkage rod 83 from rotating synchronously with the bidirectional lead screw 82, one end of the linkage rod 83 is preferably in contact with the base plate 1.

[0041] The implementation principle of a curtain wall connector in an embodiment of the present application is as follows: When installing a curtain wall panel, first fix the base plate 1 on the building wall and connect the curtain wall panel to the positioning plate 3, then rotate the mounting block 2 to the required position, and by rotating the bidirectional lead screw 82, the locking block 71 is extended into the adjacent locking groove 231, so as to lock the mounting block 2; then move the curtain wall panel towards the base plate 1, so that the connecting block 4 extends into the connecting groove 21. At this time, the locking block 51 will automatically extend into the locking groove 41 under the action of the locking spring 52, so as to lock the connecting block 4, so as to realize the relative fixation of the curtain wall panel and the building wall. If it is necessary to adjust the position of the curtain wall panel again, just remove the curtain wall panel from the positioning plate 3, then unlock and rotate the mounting block 2, and the position of the connecting groove 21 and the installation angle of the subsequent installation plate can be changed to meet different decoration requirements, with strong practicability.
