Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, specifically a prefabricated building curtain wall. Background Technology

[0002] With the acceleration of urbanization, the demand for building curtain walls for high-rise buildings and large public facilities is increasing. As a core component of building facades, building curtain walls not only need to meet aesthetic requirements, but also need to take into account safety, construction efficiency, and ease of maintenance in the later stages.

[0003] Traditional curtain wall installations often use bolt fixing or welding methods, which have the following problems: for example, low construction efficiency, each curtain wall panel needs to be tightened one by one with multiple bolts, high-altitude operations are time-consuming and labor costs are high; there are also significant safety hazards, especially in windy weather, where loose bolts or welding defects may cause the curtain wall panel to fall off. To solve the above problems, we propose a prefabricated building curtain wall. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model discloses a prefabricated building curtain wall. The technical solution adopted includes an installation plate and a curtain wall panel. The four corners of the installation plate are respectively provided with installation holes. The curtain wall panel is provided in front of the installation plate, and quick-installation units symmetrically arranged on the rear side of the curtain wall panel are movably engaged on L-shaped brackets symmetrically arranged on the front side of the installation plate. The quick-installation unit includes a quick-installation base, a pressure plate, a guide rod, a first compression spring, a driven plate, a second compression spring, a plug rod, a blocking plate, and a pull ring. The pressure plate and the driven plate are slidably installed at the upper and lower ends of the quick-installation base, and blocking plates are provided at the left and right ends between the pressure plate and the driven plate. The plates are detachably installed in the rectangular through slots at the left and right ends of the quick-release base. Pull rings are fixedly installed at the ends of the blocking plates located outside the rectangular through slots. The upper and lower end surfaces of the blocking plates are in movable contact with the surfaces of the pressure plate and the driven plate, respectively. Four guide rods are arranged in an evenly spaced array at the other end of the pressure plate. A first compression spring is fitted on the outer side of each guide rod. The other end of each guide rod is slidably installed in the guide hole provided on the quick-release base. Insert rods are symmetrically arranged on the left and right sides of the other end of the driven plate. A second compression spring is fitted on the outer side of each insert rod. The other end of each insert rod passes through the through hole provided on the quick-release base and is movably inserted into the insertion hole provided on the L-shaped card holder.

[0005] As a preferred embodiment of this invention, the elastic force of the first compression spring is greater than that of the second compression spring.

[0006] As a preferred embodiment of this utility model, the mounting hole is a countersunk hole.

[0007] As a preferred technical solution of this utility model, it also includes anti-slip protrusions, which are hemispherical protrusions and are evenly arrayed around the rear side of the curtain wall panel.

[0008] As a preferred technical solution of this utility model, it also includes weight reduction channels, wherein three weight reduction channels are provided, and the weight reduction channels are respectively provided at the upper and lower ends and the middle of the mounting plate.

[0009] As a preferred embodiment of this utility model, the left end of the L-shaped card holder is provided with a limiting block, and the limiting block limits the quick-release seat.

[0010] The beneficial effects of this utility model are as follows: Through the sliding snap-fit ​​design of the quick-installation unit and the L-shaped bracket, the curtain wall panel can be initially positioned by pushing it in with one hand. Combined with the spring-driven automatic locking mechanism, installation can be completed without additional tools, significantly shortening the time required for high-altitude operations. The dual-spring force differential design, with the first compression spring having a greater force than the second, ensures that the insertion rod is stably inserted into the socket in the locked state. Even under external impact or vibration, the second compression spring absorbs energy, while the first compression spring continuously provides pre-tension to prevent the insertion rod from accidentally coming out. The weight-reducing through-slot design reduces the physical exertion of operators during high-altitude operations, while also reducing the load on hoisting equipment and improving construction safety.

[0018] Example 1

[0019] like Figures 1 to 6As shown, this utility model discloses a prefabricated building curtain wall. The technical solution includes a mounting plate 1 and a curtain wall panel 2. Mounting holes 7 are provided at the four corners of the mounting plate 1. These mounting holes 7 are countersunk holes. Operators use external mounting bolts to connect to the external building wall through the mounting holes 7, thereby fixing the mounting plate 1. Simultaneously, the countersunk hole design effectively "hides" the external mounting bolt heads, preventing them from affecting the installation of the curtain wall panel 2. It also includes weight-reducing grooves 8, three of which are respectively located at the top, bottom, and middle of the mounting plate 1. Through the design of the weight-reducing grooves 8, the mounting plate 1 reduces its overall weight through a "hollowed-out" structure, reducing the difficulty of high-altitude operations. A front end of the mounting plate 1 is provided with… The curtain wall panel 2, and the quick-installation units 5 symmetrically arranged on the rear side of the curtain wall panel 2, are movably latched onto the L-shaped brackets 3 symmetrically arranged on the front side of the mounting plate 1. The quick-installation units 5 also include anti-slip protrusions 6, which are hemispherical protrusions evenly arrayed around the rear side of the curtain wall panel 2. The design of the anti-slip protrusions 6 increases the friction between the operator's hand and the curtain wall panel 2 during installation, preventing slippage. Limiting blocks 9 are respectively provided at the left end of the L-shaped brackets 3, and the limiting blocks 9 respectively limit the quick-installation base 51. The limiting blocks 9 limit the end of the quick-installation base 51, ensuring that the quick-installation base 51 slides to the preset position, so that the insertion rod 57 inside the quick-installation base 51 is precisely aligned with the insertion hole 4 on the L-shaped bracket 3. The quick-installation unit 5 includes the quick-installation base 51, the pressure plate 52, and the guide rod. 53. A first compression spring 54, a driven plate 55, a second compression spring 56, a plug rod 57, a blocking plate 58, and a pull ring 59. A pressure plate 52 and a driven plate 55 are slidably installed at the upper and lower ends of the quick-release base 51, respectively. Blocking plates 58 are provided at the left and right ends between the pressure plate 52 and the driven plate 55. The blocking plates 58 are detachably installed in rectangular slots at the left and right ends of the quick-release base 51, and pull rings 59 are fixedly installed at the ends of the blocking plates 58 located outside the rectangular slots. The upper and lower surfaces of the blocking plates 58 are in movable contact with the surfaces of the pressure plate 52 and the driven plate 55, respectively. Four guide rods 53 are arranged in an equidistant array at the other end of the pressure plate 52, and a first compression spring 54 is fitted onto the outer side of each guide rod 53. The other end of the plate 53 is slidably installed in the guide holes provided on the quick-release base 51. The other end of the driven plate 55 is symmetrically provided with insert rods 57 on the left and right sides. The outer side of the insert rods 57 is fitted with second compression springs 56, and the other end of the insert rods 57 passes through the through holes provided on the quick-release base 51 and is movably inserted into the insertion holes 4 provided on the L-shaped card holder 3. The elastic force of the first compression spring 54 is greater than that of the second compression spring 56. By pulling the pull ring 59 outward, the blocking plate 58 is completely pulled out from the rectangular through slots at both ends of the quick-release base 51. At this time, the constraint of the blocking plate 58 on the pressure plate 52 is released. Since the elastic force of the first compression spring 54 is greater than that of the second compression spring 56, the pressure plate 52 moves towards the driven plate 55 under the push of the first compression spring 54.The guide rod 53 ensures smooth movement. Subsequently, the movement of the pressure plate 52 pushes the driven plate 55 to move synchronously. The driven plate 55 further drives the insertion rods 57 on its left and right sides through the through holes of the quick-installation seat 51, finally inserting them into the insertion holes 4 of the L-shaped bracket 3. During this process, the second compression spring 56 is compressed, but its elasticity is insufficient to overcome the force of the first compression spring 54, thus ensuring that the insertion rods 57 are stably locked in the insertion holes 4, completing the rapid installation of the curtain wall panel 2.

[0020] The working principle of this utility model is as follows: First, the mounting plate 1 is fixed to the surface of the building wall by passing external mounting bolts through the countersunk mounting holes 7 at the four corners of the mounting plate 1. The weight-reducing groove 8 reduces the weight of the mounting plate 1, thereby reducing the installation difficulty. The anti-slip protrusion 6 on the back side of the curtain wall panel 2 can increase the friction between the operator's hand and the curtain wall panel 2 during installation, preventing slippage. After the mounting plate 1 is fixed, when installing the curtain wall panel 2, the quick-installation seat 51 on the back side of the curtain wall panel 2 is slid horizontally into the L-shaped bracket 3. The limiting block 9 limits the end of the quick-installation seat 51, thereby ensuring that the insertion rod 57 can be smoothly inserted into the insertion hole 4. Second, when locking the quick-installation seat 51, the blocking plate 58 is pulled outward from both ends of the quick-installation seat 51 by pulling the pull ring 59 outward. When the rectangular through slot is completely removed, the constraint of the blocking plate 58 on the pressure plate 52 is released. Since the elastic force of the first compression spring 54 is greater than that of the second compression spring 56, the pressure plate 52 moves towards the driven plate 55 under the push of the first compression spring 54, and the movement is kept stable by the guide rod 53. Subsequently, the movement of the pressure plate 52 pushes the driven plate 55 to move synchronously. The driven plate 55 further drives the insertion rods 57 on its left and right sides to pass through the through holes of the quick-installation seat 51 and finally insert into the insertion hole 4 of the L-shaped card seat 3. During this process, the second compression spring 56 is compressed, but its elastic force is not enough to overcome the force of the first compression spring 54, thereby ensuring that the insertion rod 57 is stably locked in the insertion hole 4, completing the quick installation of the curtain wall panel 2.
