Description

Technical Field

[0001] This utility model belongs to the field of curtain wall installation technology, and in particular relates to a quick connection device for curtain walls. Background Technology

[0002] A curtain wall is a non-load-bearing exterior wall cladding for a building. It is hung up like a curtain, hence the name "curtain wall". It is a lightweight wall structure with decorative effect commonly used in modern large and high-rise buildings. It consists of panels and a supporting structural system. It can have a certain displacement capacity relative to the main structure or a certain deformation capacity itself. It is an exterior building envelope or decorative structure that does not bear the load of the main structure. During the installation of a curtain wall, a connecting device is required to connect the curtain wall to the exterior wall of the building.

[0003] Most current connection devices are fixed to the wall with bolts. After fixing, the overall angle cannot be adjusted, which means that the curtain wall angle cannot be adjusted after installation, resulting in a decrease in the flatness of the curtain wall installation and reducing the aesthetics of the building's exterior curtain wall. To address this, a quick connection device for curtain walls is provided. Utility Model Content

[0004] The purpose of this utility model is to propose a quick connection device for curtain walls in order to solve the problem that the angle of most current connection devices cannot be changed after they are fixed.

[0030] In specific implementation, such as Figures 1-4As shown, this utility model provides a technical solution: a curtain wall quick connection device, including a main beam 1, the main beam 1 is cross-shaped, and frame 2 is fixedly installed at each of the four ends of the main beam 1. The frame 2 are interconnected, and placement grooves 5 are provided on the side walls of the main beam 1 and the frame 2. A buffer pad is fixedly installed on the inner wall of the placement groove 5; a connecting component 3 is disposed on the side wall of the main beam 1 for connecting the connecting device to the wall surface; and an installation component 4 is disposed on the main beam 1 for fixing the curtain wall within the placement frame; wherein, the connecting component 3 includes a connecting beam 31, the connecting beam 31 has the same shape as the main beam 1, both being cross-shaped, and a connecting seat 32 is fixedly installed on the outer surface of the connecting beam 31. The connecting seats 32 are located at the head end of the connecting beam 31 and are symmetrical in pairs. The inner wall of the connecting seat 32... A fixing bolt 33 is rotatably mounted on the upper part of the connecting beam 31. One end of the fixing bolt 33 passes through the interior of the connecting seat 32. A slot is provided inside the connecting beam 31. A worm gear 34 is rotatably mounted on the inner wall of the cavity of the connecting beam 31. One end of the worm gear 34 extends to the outside of the connecting beam 31, and the other end of the worm gear 34 extends into the slot of the connecting beam 31. A worm wheel 35 is rotatably mounted on the inner side wall of the slot of the connecting beam 31. A threaded hole is provided on the inner surface of the worm wheel 35. A threaded rod 36 is threadedly mounted on the worm wheel 35 through the threaded hole. The worm wheel 35 and the worm gear 34 mesh with each other. One end of the threaded rod 36 extends to the outside of the connecting beam 31. A universal joint 37 is fixedly mounted on one end of the threaded rod 36. Universal joints 37 are provided at all four ends of the connecting beam 31. The four ends of the connecting beam 31 are fixedly connected to the four ends of the main beam 1 through the universal joints 37.

[0031] Holes are drilled in the wall according to the position of the fixing bolt 33. Then, the fixing bolt 33 is used with the expansion nut to fix the connecting beam 31 to the wall under the action of the connecting seat 32, thereby fixing the main beam 1 to the wall. After the curtain wall is installed, the worm gear 34 is rotated in the slot of the connecting beam 31. At this time, the worm wheel 35 will rotate on the inner wall of the slot. Under the action of the threaded hole, the threaded rod 36 will retract into the slot or move out of the slot. Under the action of the universal joint 37, the main beam 1 will move. By rotating the worm gear 34 in different positions, the main beam 1 can swing left and right or up and down, thereby adjusting the angle of the curtain wall.

[0032] like Figures 2-3As shown, the mounting assembly 4 includes a mounting cover 41, which is also cross-shaped. The mounting cover 41 is adapted to the main beam 1. Each of the four ends of the mounting cover 41 is fixedly mounted with an edge sealing plate 42. The edge sealing plates 42 are fixedly connected to each other. A sealing gasket 43 is fixedly mounted on the side wall of the mounting cover 41 and the edge sealing plate 42. A fastening bolt 44 is rotatably mounted at the center of the mounting cover 41. One end of the fastening bolt 44 extends into the interior of the mounting cover 41. A slot is provided at the center of the main beam 1. A fastening nut 6 is fixedly mounted on the inner wall of the slot. The fastening bolt 44 and the fastening nut 6 are adapted to each other.

[0033] After the main beam 1 is fixed, the curtain wall is placed into the placement groove 5 with the cooperation of the frame 2. At this time, the curtain wall comes into contact with the buffer pad in the placement groove 5. Align the fastening bolt 44 on the mounting cover 41 with the fastening nut 6 in the groove on the main beam 1. Then, by tightening the fastening bolt 44, one end of the fastening bolt 44 will move into the groove under the action of the fastening nut 6. At this time, the mounting cover 41 will move synchronously. The mounting cover 41 will drive the edge sealing plate 42 to move into the placement groove 5. Under the action of the sealing gasket 43, the curtain wall is fixed in the placement groove 5, thus completing the installation of the curtain wall. By changing the distance of the fastening bolt 44 in the groove, the connection device can be adapted to the installation of curtain walls of different thicknesses.

[0034] Working principle: Holes are drilled in the wall according to the position of the fixing bolt 33. Then, the fixing bolt 33 and the expansion nut are used to fix the connecting beam 31 to the wall under the action of the connecting seat 32, thereby fixing the main beam 1 to the wall. After the main beam 1 is fixed, the curtain wall is placed into the placement groove 5 with the cooperation of the frame 2. At this time, the curtain wall comes into contact with the buffer pad in the placement groove 5. The fastening bolt 44 on the mounting cover 41 is aligned with the fastening nut 6 in the groove of the main beam 1. Then, by tightening the fastening bolt 44, one end of the fastening bolt 44 will move into the groove under the action of the fastening nut 6. At this time, the mounting cover 41 will move synchronously. The mounting cover 41 will drive the edge sealing plate 42 to move into the placement groove 5. Under the action of the sealing gasket 43, the curtain wall is fixed in the placement groove 5, thereby completing the installation of the curtain wall.

[0035] After the curtain wall is installed, the worm gear 34 rotates in the slot of the connecting beam 31. At this time, the worm wheel 35 rotates on the inner wall of the slot. Under the action of the threaded hole, the threaded rod 36 will retract into the slot or move out of the slot. Under the action of the universal joint 37, the main beam 1 will move. By rotating the worm gear 34 at different positions, the main beam 1 can swing left and right or up and down, thereby adjusting the angle of the curtain wall.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
