Description

Technical Field

[0001] This utility model relates to the technical field of curtain wall structures, and in particular to a buffer noise reduction pad and curtain wall unit used in curtain wall structures. Background Technology

[0002] In modern building curtain wall engineering, metal curtain walls, glass curtain walls, stone curtain walls, and other types are widely used in the design of various building facades, as well as interior roofs and walls, due to their advantages such as aesthetics, flexible and convenient installation, and energy conservation and environmental protection. Their typical installation structure involves first fixing metal framing to the main building structure, and then assembling the curtain wall panels to the framing using metal connectors to ultimately form a complete curtain wall system.

[0003] In traditional installation structures, metal connectors are in direct contact with the metal frame and connected by screws. However, both are rigid metal materials, and when the ambient temperature fluctuates, differences in their coefficients of thermal expansion and contraction cause varying degrees of deformation, leading to relative displacement and friction, ultimately generating noise and affecting the comfort of the surrounding environment. Furthermore, this structure is also affected by dynamic loads on the building; for example, the curtain wall structure of the building facade is subject to wind forces, which can also cause frictional noise between the metal connectors and the metal frame. Frictional noise generated by these factors in traditional curtain wall structures has become a common problem in practical use, impacting residential and office environments. Utility Model Content

[0004] In view of the problem of frictional noise easily generated between metal connectors and metal keel in the traditional curtain wall structure, the purpose of this utility model is to provide a buffer noise reduction pad and curtain wall unit for use in curtain wall structure.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A buffer noise reduction pad for use in a curtain wall structure, comprising a limiting part 31, a connecting part 32, and a padding part 33, wherein the limiting part 31 and the padding part 33 are respectively connected to both ends of the connecting part 32.

[0007] Furthermore, the buffer noise reduction pad is made of an elastic or flexible material.

[0008] Furthermore, the limiting part 31 is frustum-shaped, and the diameter of the end of the limiting part 31 that is close to the connecting part 32 is greater than the diameter of the end that is far away from the connecting part 32.

[0009] Furthermore, the connecting portion 32 is cylindrical.

[0010] Furthermore, the padding layer 33 has a circular sheet structure.

[0011] Furthermore, the padding layer 33 has a square sheet structure.

[0012] Furthermore, the buffer noise reduction pad has a groove 34, which passes through the limiting part 31 and extends into the connecting part 32.

[0013] Furthermore, the groove 34 is a circular groove.

[0014] A curtain wall unit for use in a curtain wall structure includes a curtain wall panel 1, connectors 2, and a buffer noise reduction pad. Multiple connectors 2 are installed on the edge of the curtain wall panel 1, and the connectors 2 are used to connect to the curtain wall's keel. Each connector 2 has a through hole 21, through which a buffer noise reduction pad is detachably installed. When the connector 2 is connected to the curtain wall's keel, the padding portion 33 of the buffer noise reduction pad is located between the connector 2 and the curtain wall's keel.

[0015] Furthermore, the edge of the curtain wall panel 1 is provided with a bending portion 11; the connector 2 includes a first connecting plate 22 and a second connecting plate 23, one side of the first connecting plate 22 is connected to one side of the second connecting plate 23, and the first connecting plate 22 and the second connecting plate 23 are perpendicular to each other; the first connecting plate 22 is connected to the bending portion 11, and the through hole 21 is provided on the second connecting plate 23.

[0016] Because this utility model employs the aforementioned technology, it has the following positive effects compared to existing technologies:

[0017] (1) The curtain wall unit of this utility model includes a curtain wall panel, a connector, and a buffer noise reduction pad. The buffer noise reduction pad is snapped into the connector through a through hole on the connector. The buffer noise reduction pad is an elastic or flexible structure, preferably made of rubber. The buffer noise reduction pad of this utility model includes a limiting part, a connecting part, and a padding part. The limiting part and the padding part are respectively connected to both ends of the connecting part. When the connector is connected to the keel of the curtain wall, the padding part is located between the connector and the keel of the curtain wall, avoiding direct contact between the metal connector and the metal keel. This reduces friction noise between structural components under the influence of the external environment. In addition, it also has the functions of shock absorption and sound insulation. This utility model can be applied to structures such as metal curtain walls, glass curtain walls, and stone curtain walls. Attached Figure Description
