Description

Technical Field

[0001] The utility model relates to the technical field of curtain wall design, in particular to a curtain wall combined frame with noise reduction and sound insulation effects. Background Art

[0002] Curtain walls are a type of building exterior wall system, usually made of aluminum alloy, glass, steel and other materials. This exterior wall system is designed to be installed on the outside of the building structure and does not bear structural loads. Curtain walls usually play the role of heat insulation, sound insulation, waterproofing and aesthetics, while also providing good lighting performance. In modern architecture, curtain walls have become a very popular form of exterior wall system, which can give buildings a light and modern appearance, while also meeting the requirements of buildings for thermal insulation, energy saving and environmental adaptability.

[0003] A Chinese patent has been published (authorization announcement number CN220848238U). This patent technology is a noise reduction curtain wall, which involves the field of wall construction technology. It aims to solve the problem that the wall structure in the prior art is easy to transmit sound waves. The key points of its technical solution are: it includes a keel and a wall panel installed on the keel. The keel includes a plurality of vertical keels and a horizontal keel connecting the plurality of vertical keels. A connecting frame is fixedly connected to the vertical keel. The wall panel is installed on the connecting frame. The connecting frame includes a first connecting plate, a second connecting plate, and a plurality of hinged frames arranged between the first connecting plate and the second connecting plate. The hinged frame includes two intersecting hinged pieces facing opposite directions. A noise reduction curtain wall of the utility model is fixedly connected to the wall panel and the vertical keel by connecting the connecting frame. In the process of vibration transmission, the transmission path is extended by setting the hinged piece, and the vibration loss is increased by setting the vibration absorbing pad to reduce noise pollution.

[0004] However, there are still some shortcomings in this patent. The existing curtain wall design lacks the effect of multiple combined noise reduction, resulting in the curtain wall's unsatisfactory sound blocking effect, affecting the normal working environment of people in the building. Therefore, those skilled in the art provide a curtain wall combination frame with noise reduction and sound insulation effects to solve the problems raised in the above background technology. Utility Model Content

[0005] 1. Technical solution

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a curtain wall composite frame with noise reduction and sound insulation effects, comprising a main board, a movable board 1 and a movable board 2, a vacuum groove is fixed on one side of the main board, a movable board 1 is arranged on the outer side of the vacuum groove, a groove 1 distributed in a longitudinal linear array is arranged on the surface of the movable board 1, a movable board 2 is arranged on the outer side of the movable board 1, and a groove 2 distributed in a transverse linear array is arranged on the surface of the movable board 2;

[0008] This device is mainly designed as a curtain wall frame structure, which uses triple sound insulation effects to achieve good noise reduction function. It mainly uses movable plate 1 and movable plate 2 with moving effects to achieve noise blocking. The surfaces of movable plate 1 and movable plate 2 are provided with grooves 1 and grooves 2 with staggered designs. The staggered design is used to reduce sound waves. The vacuum groove fitted with the main board can use the internal vacuum design to reduce the straight-line propagation of sound. The frame design of the curtain wall is realized by using the reduction processing effects of three sound waves, which has good noise reduction and sound insulation effects.

[0009] Furthermore, a glass body is arranged on the side of the mainboard facing away from the vacuum tank, and the glass body is fixed inside the mounting groove on one side of the mainboard by limiting pins. The glass body is common tempered glass on the market and is mainly installed on the outer wall of the mainboard facing the outside.

[0010] Furthermore, the surface of one side of the vacuum groove facing away from the movable plate is provided with protrusions distributed in a square array. The protrusions can make the surface of one side of the vacuum groove uneven, and when the sound propagates to the surface, it will be irregularly reflected, thereby weakening the intensity of the sound.

[0011] Furthermore, a telescopic cylinder is fixed to the outer wall of the main board facing the movable plate one, a telescopic rod is inserted into the inside of the telescopic cylinder, one end of the telescopic rod is fixedly connected to one side of the movable plate one, and the movable plate one can be moved relative to the telescopic cylinder by the telescopic cylinder to achieve the effect of adjusting the distance between the movable plate one and the movable plate two. Different distances can adjust the noise propagation intensity in different occasions.

[0012] Furthermore, the surface of the telescopic rod is provided with limiting holes distributed in a linear array, the outer wall of the telescopic cylinder is rotatably installed with a screw, and the screw is inserted into the limiting hole. The screw and the limiting hole can be used to lock the position after adjusting the position of the movable plate.

[0013] Furthermore, a telescopic cylinder 2 is fixed to the outer wall of the main board facing the movable plate 1, a telescopic rod 2 is inserted into the telescopic cylinder 2, one end of the telescopic rod 2 is fixedly connected to one side of the movable plate 2, and the movable plate 2 can be moved by the telescopic cylinder 2 to achieve the effect of adjusting the distance between the vacuum groove and the movable plate 2. Different distances in different occasions will adjust the strength of noise propagation.

[0014] Furthermore, the surface of the second telescopic rod is provided with two limiting holes distributed in a linear array, and the outer wall of the second telescopic cylinder is rotatably installed with two screws, and the two screws are inserted into the inside of the two limiting holes. The position of the second movable plate can be locked after adjusting the position of the second screw and the two limiting holes.

[0015] Furthermore, the inner surfaces of the movable plate 1 and the movable plate 2 are both designed to be arc-shaped. The arc-shaped design can mainly prevent the sound from being directly reflected when it propagates to the surface but be reflected back at a certain focal point, thereby reducing the internal transmission efficiency of the sound.

[0016] 2. Beneficial effects

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] The device can use screws 1 and 2 in conjunction with limiting holes 1 and 2 to adjust the distance between the moving plates 1 and 2 relative to the vacuum groove and the spacing between the moving plates 1 and 2, and conveniently adjust the spacing difference to achieve the best noise blocking effect. The staggered grooves 1 and 2 can reduce the propagation of sound with an irregular design.

[0019] This device can take advantage of the fact that sound cannot be transmitted in a vacuum, and use the vacuum groove to reduce the penetration of sound. The vibration effect of the vacuum groove itself is reduced by its unique noise reduction material (glass fiber), which reduces this mechanical vibration, thereby further reducing the propagation of sound and achieving a good noise reduction effect.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
