Description

Technical Field

[0001] This utility model is a curtain wall dry-hanging device, belonging to the field of curtain wall technology. Background Technology

[0002] Dry-hanging curtain walls is a technique for exterior wall decoration and protection. It suspends curtain wall panels (such as stone, aluminum, and glass) from the building structure using metal hangers, eliminating the need for traditional wet work (such as mortar application). This installation method not only improves construction efficiency but also enhances the building's aesthetics and durability. Before dry-hanging, aluminum profile beams need to be installed on the exterior wall. The side of the aluminum profile beam facing away from the wall is then fitted with a snap-fit ​​beam on the back of the curtain wall using self-tapping screws. However, using self-tapping screws to connect the snap-fit ​​beam and the aluminum profile beam restricts their relative position. Due to the reaction force experienced by the self-tapping screws during the tapping process, the snap-fit ​​beam may not be level. Adjusting the relative position of the snap-fit ​​beam and the aluminum profile beam after installation is time-consuming and labor-intensive. Therefore, a dry-hanging curtain wall device that allows for convenient adjustment of the relative position of the snap-fit ​​beam and the aluminum profile beam is needed. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a curtain wall dry-hanging device to solve the problems mentioned in the background technology. This utility model makes it convenient to adjust the relative position of the snap-fit ​​beam and the aluminum profile beam.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a curtain wall dry-hanging device, comprising a stone curtain wall, with two vertically arranged aluminum profile beams on the back of the stone curtain wall, and two horizontally arranged snap-fit ​​beams between the stone curtain wall and the aluminum profile beams. Multiple snap-fit ​​ears that mate with the snap-fit ​​beams are installed on the side of the stone curtain wall facing the aluminum profile beams. Ear plates are installed at both ends of the snap-fit ​​beams, and elongated holes are formed on the upper surface of the ear plates. These elongated holes are arranged along the length of the snap-fit ​​beams. A gap exists between the ear plates and the aluminum profile beams. Vertically arranged screws are inserted into the elongated holes, and both ends of the screws are connected to the aluminum profile beams. Adjusting nuts are provided on both sides of the elongated holes along the length of the screws, and the adjusting nuts are threaded onto the screws.

[0005] Furthermore, positioning ears are provided on both the upper and lower sides of the ear plate. The positioning ears are connected and fixed to the aluminum profile beam. The side of the positioning ear facing the ear plate has a through hole that matches the elongated hole. The two ends of the screw pass through the through holes on the two positioning ears respectively. The two ends of the screw are threaded with limit nuts. The limit nuts are located on the side of the positioning ear away from the ear plate.

[0006] Furthermore, the ear plate has a first rounded corner at the two corners away from the snap-fit ​​beam, and the positioning ear has a second rounded corner at the two corners away from the aluminum profile beam.

[0007] Furthermore, a first reinforcing rib is installed between the ear plate and the connecting beam, and a second reinforcing rib is installed between the positioning ear and the aluminum profile beam.

[0008] Furthermore, the snap-fit ​​beam includes a horizontal plate portion, an upper L-shaped portion is installed at the upper end of the horizontal plate portion, and a lower L-shaped portion is installed at the lower end of the horizontal plate portion. The snap-fit ​​ear includes a plate portion, which is connected and fixed to the stone curtain wall by fasteners. An upper snap-fit ​​portion for snapping onto the upper L-shaped portion is connected and fixed at the upper end of the plate portion. The upper snap-fit ​​portion has an L-shaped structure. A lower snap-fit ​​portion for snapping into the space formed between the lower L-shaped portion and the horizontal plate portion is connected and fixed at the lower end of the plate portion. The lower snap-fit ​​portion has an L-shaped structure.

[0009] Furthermore, the upper L-shaped part, the lower L-shaped part, and the horizontal plate part are integrally formed, and the upper snap-fit ​​part, the lower snap-fit ​​part, and the plate part are integrally formed.

[0010] The beneficial effects of this utility model are:

[0011] 1. After the screw passes through the elongated hole on the ear plate and the through hole on the positioning ear, tighten the limit nuts at both ends of the screw. The limit nuts and positioning ears cooperate to complete the assembly of the screw and the aluminum profile beam, and at the same time complete the assembly of the snap-fit ​​beam and the aluminum profile beam. When the limit nuts and screw cannot be properly separated due to corrosion, the screw can be cut off by using the gap between the positioning ear and the ear plate, which facilitates the replacement of the snap-fit ​​beam later.

[0012] 2. Adjust the height of the ear plate along the screw. At this time, the height of the end of the snap-fit ​​beam changes. After the snap-fit ​​beam is in a horizontal state, use two adjusting nuts to limit the relative position of the ear plate and the screw, so that the relative position of the snap-fit ​​beam and the aluminum profile beam remains unchanged. Compared with using self-tapping screws to connect the snap-fit ​​beam and the aluminum profile beam, it is more convenient to adjust the relative position of the snap-fit ​​beam and the aluminum profile beam, reducing the construction difficulty of dry hanging curtain walls.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a curtain wall dry-hanging device, including a stone curtain wall 1, with two vertically arranged aluminum profile beams 2 on the back of the stone curtain wall 1, and two horizontally arranged snap-fit ​​beams between the stone curtain wall 1 and the aluminum profile beams 2. Multiple snap-fit ​​ears that cooperate with the snap-fit ​​beams are installed on the side of the stone curtain wall 1 facing the aluminum profile beams 2. Each snap-fit ​​beam includes a horizontal plate portion 3, with an upper L-shaped portion 8 installed at the upper end of the horizontal plate portion 3 and a lower L-shaped portion 7 installed at the lower end. The upper L-shaped portion 8 and the lower L-shaped portion 7 are integrally formed with the horizontal plate portion 3. The snap-fit ​​ears include plate portions 12. The panel 12 is connected and fixed to the stone curtain wall 1 by fasteners. The upper end of the panel 12 is connected and fixed with an upper snap-fit ​​part 9 for snapping onto the upper L-shaped part 8. The upper snap-fit ​​part 9 has an L-shaped structure. The lower end of the panel 12 is connected and fixed with a lower snap-fit ​​part 13 for snapping into the space formed by the lower L-shaped part 7 and the horizontal plate part 3. The lower snap-fit ​​part 13 has an L-shaped structure. The upper snap-fit ​​part 9, the lower snap-fit ​​part 13 and the panel 12 are integrally formed, so that the upper L-shaped part 8 is snapped onto the upper snap-fit ​​part 9, and the lower L-shaped part 7 is snapped into the space formed by the lower L-shaped part 7 and the horizontal plate part 3, thus completing the snap-fit ​​of the snap-fit ​​ear and the snap-fit ​​beam.

[0023] See Figures 1-6Both ends of the snap-fit ​​beam are equipped with ear plates 6. A first reinforcing rib is installed between the ear plate 6 and the connection part of the snap-fit ​​beam. The two corners of the ear plate 6 away from the snap-fit ​​beam are machined with a first rounded corner. An elongated hole 14 is opened on the upper surface of the ear plate 6. The elongated hole 14 is arranged along the length direction of the snap-fit ​​beam. There is a gap between the ear plate 6 and the aluminum profile beam 2. A vertically arranged screw 5 is inserted into the elongated hole 14. Both ends of the screw 5 are connected to the aluminum profile beam 2. Adjustable... Adjusting nut 11 is threaded onto screw rod 5. Adjusting the height of ear plate 6 along screw rod 5 changes the height of the end of the snap-fit ​​beam. When the snap-fit ​​beam is in a horizontal state, the two adjusting nuts 11 are used to limit the relative position of ear plate 6 and screw rod 5, so that the relative position of snap-fit ​​beam and aluminum profile beam 2 remains unchanged. Compared with using self-tapping screws to connect snap-fit ​​beam and aluminum profile beam 2, it makes the adjustment of the relative position of snap-fit ​​beam and aluminum profile beam 2 more convenient and reduces the construction difficulty of dry hanging curtain wall.

[0024] See Figures 1-6 Positioning ears 4 are provided on both the upper and lower sides of the ear plate 6. The positioning ears 4 are connected and fixed to the aluminum profile beam 2. A second reinforcing rib is installed between the connection between the positioning ears 4 and the aluminum profile beam 2. The two corners of the positioning ears 4 away from the aluminum profile beam 2 are machined with second rounded corners. The side of the positioning ears 4 facing the ear plate 6 has a through hole that matches the elongated hole 14. The two ends of the screw 5 pass through the through holes on the two positioning ears 4 respectively. Both ends of the screw 5 are threaded with limit nuts 10. The limit nuts 10 are set at... Positioning ear 4 is positioned away from ear plate 6. After screw 5 passes through the elongated hole 14 on ear plate 6 and the through hole on positioning ear 4, limit nuts 10 are screwed on both ends of screw 5. The limit nuts 10 and positioning ear 4 cooperate with each other to complete the assembly of screw 5 and aluminum profile beam 2, and at the same time complete the assembly of snap-fit ​​beam and aluminum profile beam 2. When limit nuts 10 and screw 5 cannot be properly separated due to rust, screw 5 can be cut off using the gap between positioning ear 4 and ear plate 6, which facilitates the replacement of snap-fit ​​beam later.
