Description

Technical Field

[0001] This utility model relates to the field of curtain wall installation technology, specifically a connecting device for dry-hanging curtain walls. Background Technology

[0002] Dry-hanging curtain walls are a widely used high-end decorative form for modern building exteriors. Their core principle involves suspending decorative panels such as stone, ceramic tiles, aluminum panels, and terracotta panels from the exterior of the building structure using a metal frame and connecting devices. Currently, the hangers are typically fixed to horizontal beams. When encountering uneven wall surfaces, it's difficult to adjust the distance between the hangers and the wall, resulting in unevenness in the curtain wall at those locations. Furthermore, the hangers are prone to deformation due to the weight of the curtain wall over time, compromising the curtain wall's flatness.

[0003] To address the aforementioned issues, we propose a connection device for dry-hanging curtain walls. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a connecting device for dry-hanging curtain walls. In order to solve the above-mentioned technical problem, this utility model provides the following technical solution: This utility model discloses a connecting device for dry-hanging curtain walls, including a horizontal beam fixed on a longitudinal beam, and a bracket fixedly connected to the horizontal beam by a bolt assembly. The horizontal beam has an elongated hole, and the bolt assembly is inserted into the elongated hole to fix the bracket to the horizontal beam. The longitudinal beam is provided with an adjustable support mechanism for supporting the bracket, and the adjustable support mechanism is located below the horizontal beam.

[0005] Preferably, the adjustable support mechanism includes a shaft frame fixed on the longitudinal beam and located below the cross beam. A fixed-axis rotating screw is connected to the shaft frame, and a threaded sleeve is sleeved and threaded onto the screw. A lug is fixed on the outer peripheral wall of the threaded sleeve.

[0006] Preferably, the adjustable support mechanism further includes a connecting rod, and a second lug is fixed to the bottom surface of the bracket near the abutment end, and the two ends of the connecting rod are respectively rotatably connected to the first lug and the second lug.

[0007] Preferably, the bracket is provided with a pressure plate, and the bolt assembly passes through the pressure plate and presses the bracket tightly onto the crossbeam.

[0008] Preferably, a bracket is fixed on the longitudinal beam and the bracket is located above the crossbeam. A clamping screw is threaded onto the bracket and the lower end of the clamping screw is in abutting contact with the upper surface of the pressure plate.

[0009] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: the clamping force of the bolt assembly is evenly distributed to the entire bracket by the pressure plate, which improves the stable support force and clamping strength of the bracket. In addition, with the action of the clamping screw, the front end of the crossbeam is used as the fulcrum to apply downward pressure to the end of the bracket that is close to the wall, which improves the support strength and stability of the bracket for the curtain wall. Furthermore, the connecting rod, under the action of the screw and the screw sleeve, can not only adjust the distance between the bracket and the wall, but also transfer the gravity load of the bracket's hanging end to the longitudinal beam, thereby greatly improving the load-bearing capacity of the curtain wall and ensuring safety and the stability of the curtain wall support.

[0012] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Example

[0013] like Figure 1 As shown, a connecting device for dry-hanging curtain walls includes a horizontal beam 2 fixed on a longitudinal beam 1, and a bracket 4 is fixedly connected to the horizontal beam 2 by a bolt assembly 6. The horizontal beam 2 has an elongated hole 3, and the bolt assembly 6 is inserted into the elongated hole 3 to fix the bracket 4 to the horizontal beam 2. The longitudinal beam 1 is provided with an adjustable support mechanism for supporting the bracket 4, and the adjustable support mechanism is located below the horizontal beam 2.

[0014] In this embodiment, the adjustable support mechanism includes a shaft frame 9 fixed on the longitudinal beam 1, and the shaft frame 9 is located below the cross beam 2. A screw 10 is rotatably connected to the shaft frame 9, and a threaded sleeve 11 is sleeved and threadedly connected to the screw 10. A lug 12 is fixed on the outer peripheral wall of the threaded sleeve 11.

[0015] In this embodiment, the adjustable support mechanism also includes a connecting rod 13. The bottom surface of the bracket 4 is fixed with a lug 14 near the abutment end, and the two ends of the connecting rod 13 are respectively rotatably connected to lug 12 and lug 14.

[0016] In this embodiment, a pressure plate 5 is provided on the bracket 4, and the bolt assembly 6 passes through the pressure plate 5 and presses and fixes the bracket 4 to the crossbeam 2 through the pressure plate 5. A bracket 7 is fixed on the longitudinal beam 1, and the bracket 7 is located above the crossbeam 2. A clamping screw 8 is threaded on the bracket 7, and the lower end of the clamping screw 8 is in contact with the upper surface of the pressure plate 5.

[0017] The principle and advantages of this utility model: This kind of dry-hanging curtain wall connection device involves placing the bracket 4 on the horizontal beam 2 through an elongated hole 3, pressing the pressure plate 5 onto the bracket 4, and inserting the bolt assembly 6. At this time, the bolt assembly 6 does not need to be tightened. Then, the two ends of the connecting rod 13 are respectively connected to the lug 12 and lug 2 14. By rotating the screw 10, the screw sleeve 11 moves up and down, and the connecting rod 13 applies a pushing or pulling force to the bracket 4, thereby adjusting the distance between the hanging end of the bracket 4 and the wall surface, thus keeping the hanging end of the bracket 4 flush. After adjustment, the bolt assembly 6 is tightened, and the clamping screw 8 is turned... The bolt assembly 6 is tightly pressed onto the pressure plate 5, which distributes the clamping force of the bolt assembly 6 evenly across the entire bracket 4, improving the stability and clamping strength of the bracket 4. In conjunction with the tightening screw 8, it applies downward pressure to the wall-facing end of the bracket 4, using the front end of the crossbeam 2 as a fulcrum, thereby improving the support strength and stability of the bracket 4 for the curtain wall. Furthermore, the connecting rod 13, under the action of the screw 10 and the screw sleeve 11, can not only adjust the distance between the bracket 4 and the wall, but also transfer the gravity load of the bracket 4's abutment end to the longitudinal beam 1, thus greatly improving the load-bearing capacity of the curtain wall and ensuring safety and the stability of the curtain wall support.

[0018] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
