Description

Technical Field

[0001] The present application relates to the technical field of building curtain walls, and in particular to a wind-resistant structure of a building curtain wall. Background Art

[0002] A building curtain wall is a decorative and protective structure installed on the facade of a building. It is usually made of multiple layers of materials, including glass, metal, stone, etc. It can provide the building with functions such as heat insulation, waterproofing, windproofing, and sound insulation.

[0003] In high-rise buildings, the surface of the building curtain wall will be affected by higher wind force. When the wind speed is high, the air flow rate on the curtain wall surface is large, resulting in a decrease in the air pressure on the surface, thereby forming a pressure difference with the installation surface of the curtain wall, causing the curtain wall to be pressurized outward, resulting in unstable installation or even falling off, which poses a great safety hazard. Therefore, optimization is needed;

[0004] A Chinese utility model patent with publication number CN215166932U discloses a wind-resistant structure for a building curtain wall. In the technical solution of the patent, a left arc plate and a right arc plate are arranged on both sides of the front section of the curtain wall panel, and a left opening and a right opening are arranged on the surface, which are connected to the arc-shaped air duct, so that air can flow at the rear end of the curtain wall, thereby reducing the current pressure difference between the front and rear ends and reducing the installation risk of the curtain wall.

[0005] However, in the implementation of the above patent, the left arc plate and the right arc plate are fixedly connected, and the ventilation space formed between the arc-shaped air duct and the curtain wall cannot be adjusted in size. When the air volume is too large, the air passing through the ventilation space will produce greater noise, affecting the environment inside the building.

[0006] Therefore, it is necessary to provide a wind-resistant structure of a building curtain wall to solve the above problems.

[0007] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0017] During the implementation of the technical solution of the utility model, an arc plate is provided, a slide groove is provided on the mounting plate, a tension spring is provided in the slide groove, and the tension spring is fixed to the arc plate and the bottom of the slide groove respectively. When the wind speed around the curtain wall is high, the air in the wind cavity will lift up the arc plate, expand the space size of the wind cavity, and return to the initial position after the wind speed decreases, thereby reducing the noise generated.

[0018] Furthermore, the ventilation opening includes a first opening and a second opening.

[0019] Furthermore, the number of the ventilation holes is at least two, and the ventilation holes are evenly distributed along the vent.

[0020] Furthermore, the air cavity is a sealed structure.

[0021] Furthermore, the mounting plate is made of aluminum alloy.

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0033] Embodiment 1:

[0034] like Figure 1 As shown, the present application provides a building curtain wall wind-resistant structure, which is used to optimize the wind resistance of the building curtain wall 1. The wind-resistant structure includes a mounting plate 2, and a plurality of bolt holes are provided on the mounting plate 2. The mounting plate 2 is used to be fixed to the wall. In this field, a hidden frame is generally provided in the wall. The mounting plate 2 and the hidden frame can be directly fixed by bolts, and the mounting plate 2 and the building curtain wall 1 can be an integrated structure, or can be fixed by other methods such as screws, rivets, and welding. It is not limited in this embodiment. The mounting plate 2 can be made of aluminum alloy to reduce the overall weight.

[0035] The side of the mounting plate 2 is provided with a vent, which includes a first opening 11 and a second opening 12. Figure 2As shown, a plurality of ventilation holes 13 are arranged in the first opening 11, and the ventilation holes 13 are arranged through the mounting plate 2. An arc plate 3 is fixedly mounted on the back of the mounting plate 2, and the arc plate 3 and the back of the mounting plate 2 form an air cavity. After the building curtain wall 1 is installed, wind will flow from the first opening 11 through the ventilation holes 13, and then flow into the air cavity from the ventilation holes 13, and then flow out from the second opening 12, thereby reducing the pressure difference between the front and rear of the building curtain wall 1, and preventing the building curtain wall 1 from shaking or even falling off due to the pressure difference.

[0036] Embodiment 2:

[0037] In the first embodiment, by providing the curved plate 3, a wind cavity for wind to flow through is generated on the back side of the mounting plate 2, thereby reducing the pressure difference between the front and rear of the building curtain wall 1. However, since the curved plate 3 and the mounting plate 2 are fixedly connected, the size of the wind cavity formed cannot be adjusted. When the wind speed is high, a large noise will be generated and transmitted to the building. Therefore, the following improvements are made in this embodiment:

[0038] The curved plate 3 is no longer fixedly connected to the mounting plate 2. Figure 3 As shown, four slide grooves 21 are provided on the back of the mounting plate 2, and the four slide grooves 21 are distributed around the mounting plate 2. A convex block 31 is correspondingly provided on the arc plate 3, and the convex block 31 is adapted to the slide groove 21. When installing the arc plate 3, it is only necessary to insert the convex block 31 into the slide groove 21;

[0039] In order to fix the curved plate 3, a tension spring 22 is further provided at the bottom of the protrusion 31 and the slide groove 21, and the tension spring 22 is fixed to the bottom of the protrusion 31 and the slide groove 21 respectively. When the wind volume is large, the air flowing into the wind cavity will push the curved plate 3 in the direction away from the surface of the building curtain wall 1, so that the protrusion 31 moves in the direction away from the bottom of the slide groove 21, and the tension spring 22 is stretched. The distance between the curved plate 3 and the back side of the mounting plate 2 will increase, thereby increasing the area of ​​the wind cavity. When air is blown into the wind cavity, the larger wind cavity will reduce the noise generated by the air flowing through, thereby preventing the noise from affecting the environment inside the building.

[0040] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
