Abstract
Description
Technical Field
[0001] This utility model relates to the field of stone curtain wall technology, specifically to the expansion joint connection structure of dry-hanging stone curtain walls. Background Technology
[0002] Stone curtain walls are a modern architectural exterior wall decoration process. Its core feature is that stone panels are directly fixed to the building structure through a metal hanging system, forming an exterior building envelope system that does not bear the load of the main structure. This allows the structure to undergo appropriate displacement under external forces such as wind pressure and earthquakes, effectively absorbing energy and avoiding brittle failure.
[0003] Currently, the main process is to first weld and fix the adapter and the embedded parts to the exterior wall, then splice the stone slabs onto the keel in sequence, and fix them with bolts.
[0004] However, some projects currently use a close-fitting method to install stone slabs in pursuit of aesthetic effects. Since the gaps between the stone slabs are not reserved with sufficient expansion and contraction space, the stress between the stone slabs is easily concentrated due to thermal expansion and contraction, which can lead to the danger of the stone cracking or falling off. Utility Model Content
[0005] The purpose of this utility model is to provide a deformation joint connection structure for dry-hanging stone curtain walls, in order to solve the problem mentioned in the background art that some projects, in pursuit of aesthetic effects, will use a close-fitting method to install stone panels. Since the gaps between the stone panels are not reserved with sufficient expansion and contraction space, the stress between the stone panels is easily concentrated due to thermal expansion and contraction, which can lead to cracking or falling off of the stone.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a dry-hanging stone curtain wall expansion joint connection structure, including a wall frame and stone panels installed on the wall frame; and further comprising;
[0007] A connecting component is disposed on the side wall of a stone slab and is used to connect the stone slab. The connecting component includes a rubber block disposed on the side wall of the stone slab, and a connector is fixedly connected to the side wall of the stone slab.
[0008] A reinforcing assembly is disposed between the wall frame and the stone slab. The reinforcing assembly is used to fix the stone slab. The reinforcing assembly includes a reinforcing member, which is fixedly installed on the side wall of the stone slab and inserted into the side wall of the wall frame.
[0009] Preferably, the top side of the stone slab has a first horizontal groove, and the bottom side of the stone slab has a second horizontal groove, and the two sets of the first and second horizontal grooves of the stone slabs are interlocked.
[0010] Preferably, the rubber block is fixedly connected to the side wall of the first transverse groove, and the side wall of the second transverse groove is provided with a rubber groove, and the rubber block is engaged inside the rubber groove.
[0011] Preferably, the stone slab has a connecting groove on the side away from the connector, and the connector is engaged in the connecting groove of another set of stone slabs.

[0013] Preferably, the reinforcing component further includes a square plate, which is fixedly connected to the side wall of the wall frame, and the reinforcing member is inserted into the inner wall of the square plate.
[0014] Preferably, a connecting rod is fixedly connected to the side wall of the reinforcing member, and a groove is provided on the side wall of the square plate, with the connecting rod slidably connected to the inner wall of the groove.
[0015] Preferably, the end of the connecting rod is threaded with a fixing member, and the side wall of the square plate is provided with a fixing groove, and the fixing member is snapped into the inner wall of the fixing groove.

[0026] Specifically, such as Figure 2 As shown, a connecting component 3 is provided on the side wall of the stone slab 2. The connecting component 3 is used to connect the stone slab 2. The connecting component 3 includes a rubber block 302, which is provided on the side wall of the stone slab 2. A connector 303 is fixedly connected to the side wall of the stone slab 2, and a rubber layer 304 is fixedly connected to the outer peripheral wall of the stone slab 2. By providing the connecting component 3 on the side wall of the stone slab 2 and the rubber block 302 on the side wall of the stone slab 2, and by inserting the rubber block 302 into the rubber groove 3021 of another set of stone slabs 2, the stone slabs 2 can be flexibly connected. This avoids the stone slab 2 from cracking or falling off due to stress concentration caused by thermal expansion and contraction, and improves the stability of the connection. At the same time, the rubber groove 3021 can tightly protect the connection of the stone slabs 2, preventing rainwater from seeping into the stone slab 2.
[0027] The top side of the stone slab 2 is provided with a first horizontal groove 301, and the bottom side of the stone slab 2 is provided with a second horizontal groove 3011. The first horizontal groove 301 and the second horizontal groove 3011 of the two sets of stone slabs 2 are interlocked, which improves the stability of the connection between the stone slabs 2.

[0029] A connecting groove 3031 is provided on the side of the stone slab 2 away from the connector 303. The connector 303 is snapped into the connecting groove 3031 of another set of stone slabs 2, which further increases the stability and safety during connection and splicing.
[0030] Specifically, such as Figure 3 As shown, a reinforcing component 4 is provided between the wall frame 1 and the stone slab 2. The reinforcing component 4 is used to fix the stone slab 2. The reinforcing component 4 includes a reinforcing member 402, which is fixedly installed on the side wall of the stone slab 2 and inserted into the side wall of the wall frame 1. A square plate 401 is fixedly connected to the side wall of the wall frame 1. The reinforcing member 402 is inserted into the inner wall of the square plate 401. By providing the reinforcing component 4 between the wall frame 1 and the stone slab 2, and by inserting the reinforcing member 402 on the stone slab 2 into the inner wall of the square plate 401 and fixing it with the fixing member 404, the connection between the wall frame 1 and the stone slab 2 can be further strengthened, thereby further improving the stability and service life of the stone slab 2.
[0031] Specifically, such as Figure 4 As shown, a connecting rod 403 is fixedly connected to the side wall of the reinforcing member 402. A groove 4031 is provided on the side wall of the square plate 401. The connecting rod 403 is slidably connected to the inner wall of the groove 4031. A fixing member 404 is threadedly connected to the end of the connecting rod 403. A fixing groove 4041 is provided on the side wall of the square plate 401. The fixing member 404 is snapped into the inner wall of the fixing groove 4041. By inserting the reinforcing member 402 into the square plate 401, the connecting rod 403 on the reinforcing member 402 will be slidably connected to the groove 4031 on the square plate 401. The fixing member 404 is threadedly connected and snapped into the fixing groove 4041 for limitation.

At the same time, the reinforcing member 402 will be inserted into the square plate 401. Then, the fixing member 404 is threaded to the end of the connecting rod 403. Next, the rubber blocks 302 on another set of stone slabs 2 are sequentially snapped into the rubber groove 3021 and the connecting groove 3031. The above steps are repeated for installation and fixing.
