Description

Technical Field

[0001] The utility model belongs to the technical field of noise windows, and particularly relates to a window with multi-layer noise isolation. Background Art

[0002] A soundproof window is a window structure with soundproof effect. Its main structure includes an outer window frame, which is installed in a window opening of a building structure. A soundproof glass plate, such as a thickened tempered glass plate, is installed on the outer window frame.

[0003] According to different uses of the soundproof window, it is mostly a sliding window, a hinged window, a French window, etc. Among them, the French window is widely used in building structures because of its large area and high light transmittance. However, the subsequent drawback is that: since the large-area French window uses tempered glass plates as soundproof and protective walls, its soundproof effect is slightly worse than that of traditional concrete walls.

[0004] Especially for residents sensitive to noise, after installing and using a large-area French window, it is found that obvious noise can still be heard after soundproofing. Especially at night when the external environment is quiet, intermittent noises such as train whistles can still penetrate the glass plate of the French window and enter the building structure, disturbing the normal rest of the residents.

[0005] The main reason is that the glass plate is a rigid flat plate. Under noise, especially high-frequency noise, the glass plate on the large-area French window vibrates, resulting in still having noise indoors. While the concrete wall has a better soundproof effect.

[0006] Therefore, in the actual installation process, for large-area French windows located in noise areas (such as near a railway station, when a train enters the station and whistles, especially when whistling at night, the noise is even greater), it is obviously impossible to effectively block the noise.

[0007] The main reason for the above technical defects is that the glass plates used on the French window have too large an area and are directly in contact with the outside, so it is impossible to effectively block high-decibel noise. Content of the Utility Model

[0008] Based on the above background, the purpose of the utility model is to provide a window with multi-layer noise isolation.

[0009] To achieve the above purpose, the utility model adopts the following technical solutions:

[0010] A window with multi-layer noise isolation includes an outer window frame, and an installation opening for installing a glass plate is provided in the outer window frame;

[0011] A plurality of installation convex plates are respectively fixedly connected to the top and bottom in the installation opening, and a glass plate is fixedly assembled and connected between adjacent installation convex plates;

[0012] The glass plate is hermetically arranged between the inner side walls of the mounting openings, and a sealed cavity is formed between adjacent glass plates;

[0013] The sealed cavity is filled with damping liquid;

[0014] A feed pipe structure and a vent pipe structure are assembled and connected to the lower end of the outer window frame;

[0015] The discharge ends of the feed pipe structure communicate with the sealed cavity respectively, and the exhaust ends of the vent pipe structure communicate with the sealed cavity respectively.

[0016] Preferably, clamping grooves are formed on the top, bottom, left side wall and right side wall of the outer window frame;

[0017] The clamping grooves are clamped on the window opening.

[0018] Preferably, a sealing gasket is fixedly connected to the glass plate, and the sealing gasket elastically presses against the inner side wall of the mounting opening.

[0019] Preferably, both the feed pipe structure and the vent pipe structure include a horizontal pipe penetrating the outer window frame, and a plurality of short pipes communicating with the sealed cavity are communicated with the horizontal pipe;

[0020] The short pipes penetrate the side wall of the outer window frame.

[0021] Preferably, a valve is assembled and connected to the horizontal pipe.

[0022] Preferably, baffles respectively blocking the feed pipe structure and the vent pipe structure are fixedly connected to the rear side wall of the outer window frame.

[0023] Preferably, a plurality of mutually matching mounting holes are formed on the glass plate, the mounting convex plate and the outer window frame;

[0024] Sealing screws are fastened between the mounting holes.

[0025] Preferably, panel structures are respectively fixedly connected to the top and bottom of the outer window frame.

[0026] Preferably, the panel structure includes a corrugated panel, and a plurality of curved convex parts are integrally formed on the corrugated panel;

[0027] During the installation process, the corrugated panel is embedded into the sinking grooves formed at the top and bottom of the window opening.

[0028] The utility model has the following beneficial effects:

[0029] 1. The multi-layer glass plates are used to block noise layer by layer. Under such layer-by-layer blocking, the noise entering the room through the floor-to-ceiling windows has been significantly reduced. No matter how thick the traditional single-layer glass plate is, the decibel level of the noise entering the room is higher than that of the multi-layer spaced glass plates. The reason is that the multi-layer glass plates achieve layer-by-layer noise reduction. After the noise generates vibration on one glass plate, it is conducted to the next layer of glass plate through the air in the sealed cavity. The air in the sealed cavity can be pre-exhausted to form a relatively vacuum state, thereby further reducing the conduction of noise.

[0030] 2. During the implementation process, open the valve on the vent pipe structure located at the upper end, pump silicone oil from the feed pipe structure at the lower end. After pumping to a certain height, at this time, connect the vent pipe structure to the negative pressure pump, completely evacuate the air in the sealed cavity, then close the valve on the vent pipe structure, and continue to pump oil until the sealed cavity is completely filled with silicone oil for noise reduction. By this method, the sealed cavity is completely filled with silicone oil for noise reduction, and the characteristics of high viscosity, transparency, thermal stability, and difficulty in vibration of silicone oil are utilized to achieve layer-by-layer noise reduction.

[0041] Embodiment 1

[0042] As Figures 1-5 shown, a multi-layer noise-isolating window includes an outer window frame 2, and an installation opening for installing a glass plate is provided in the outer window frame 2; a plurality of installation convex plates 4 are respectively fixedly connected to the top and bottom in the installation opening, and a glass plate 1 is fixedly assembled and connected between adjacent installation convex plates 4.

[0043] Specifically, the top and bottom of the glass plate 1 are clamped by adjacent installation convex plates 4, thereby maintaining a relatively stable installation. The specific method is as follows: The installation method is the same as that of the floor-to-ceiling window glass plate 1. A plurality of mutually matching installation holes 41 are provided on the glass plate 1, the installation convex plates 4, and the outer window frame 2; a sealing screw is fastened between the installation holes 41. That is, after the sealing screw (a rubber sealing sleeve is sleeved on the sealing screw) penetrates from one side of the outer window frame 2, it sequentially penetrates the installation holes 41 on the installation convex plate 4 and the glass plate 1, and then a locking nut is fastened for positioning.

[0044] In the above manner, multiple glass plates 1 are stably installed. The adjacent glass plates 1 are arranged at intervals. Therefore, since the glass plate 1 and the outer window frame 2 are sealed, a sealed cavity is formed between the adjacent glass plates 1.

[0045] In the above - mentioned manner, the multi - layer glass plate 1 is used to block noise layer by layer. Under such layer - by - layer blocking, the noise entering the room through the floor - to - ceiling window has been significantly reduced. However, no matter how thick the traditional single - layer glass plate 1 is thickened, the decibel level of the noise entering the room is larger than that of the multi - layer spaced glass plate 1. The reason is that the multi - layer glass plate 1 realizes layer - by - layer noise reduction. After the noise generates vibration on one glass plate 1, it is conducted to the next - layer glass plate 1 through the air in the sealed cavity. And the air in the sealed cavity can be pre - evacuated to form a relatively vacuum state, thereby further reducing the conduction of noise.

[0046] To improve the sealing performance, in the existing manner, a sealing gasket 11 is fixedly connected to the glass plate 1 (the sealing gasket 11 is sleeved on the outer side wall of the glass plate 1), and the sealing gasket 11 elastically presses against the inner side wall of the installation opening.

[0047] Embodiment 2

[0048] As Figures 1-5 shown, on the basis of the structure of Embodiment 1 in this embodiment, in order to enhance the sound insulation effect, a damping liquid is filled in the above - mentioned sealed cavity; the damping liquid is preferably a transparent liquid, specifically a conventional medium such as silicone oil disclosed in the prior art. The high - viscosity silicone oil is used to reduce the penetration of sound between the glass plates 1. And the use of high - viscosity silicone oil realizes noise blocking. And because the silicone oil is located in the sealed cavity, and the sealed cavity is formed by adjacent glass plates 1, therefore, through this structure, a multi - layer silicone oil damping layer is realized. By this means, the effect of noise passing through between the glass plates 1 is greatly reduced.

[0049] Specifically, a feed - pipe structure 5 and an air - release pipe structure are assembled and connected to the lower end of the outer window frame 2. That is, during the oil - filling process, the silicone oil is pumped into each independent sealed cavity through the feed - pipe structure 5.

[0050] Specifically, the sealed cavity is formed by the adjacent glass plates 1 and the side of the outer window frame 2. Therefore, both the feed - pipe structure 5 and the air - release pipe structure include a horizontal pipe 51 penetrating the outer window frame 2, and a plurality of short - through pipes 511 communicating with the sealed cavity are connected to the horizontal pipe 51; the short - through pipes 511 penetrate the rear side wall of the outer window frame 2 (that is, the discharge ends of the feed - pipe structure 5 are respectively communicated with the sealed cavity, and the exhaust ends of the air - release pipe structure are respectively communicated with the sealed cavity).

[0051] And a valve (not shown in the figure) is assembled and connected to the horizontal pipe 51.

[0052] During operation, open the valve (not shown in the figure) on the vent pipe structure at the upper position, pump silicone oil from the feed pipe structure 5 at the lower position. After pumping to a certain height, at this time, connect the vent pipe structure to the negative pressure pump, completely evacuate the air in the sealed cavity, then close the valve on the vent pipe structure, and continue to pump oil until the sealed cavity is completely filled with silicone oil.

[0053] In this way, the sealed cavity is completely filled with silicone oil for noise reduction. By utilizing the characteristics of high viscosity, transparency, thermal stability, and difficulty in vibration of silicone oil, the noise is reduced layer by layer.

[0054] A baffle 6 for separately blocking the feed pipe structure 5 and the vent pipe structure is fixedly connected to the rear side wall of the outer window frame 2.

[0055] Embodiment 3

[0056] As Figures 1-5 shown, on the basis of the structure of Embodiment 1, this embodiment has the same installation method of the window opening structure as the existing outer window frame 2. Slots are provided on the top, bottom, left side wall, and right side wall of the outer window frame 2; the slots are clamped on the window opening and sealed with sealant after being fixed.

[0057] Meanwhile, panel structures are fixedly connected to the top and bottom of the outer window frame 2 respectively. Embedded installation is achieved through the panel structures, that is, during the construction and installation process, sinking grooves are opened at the top and bottom in the window opening, and the panel structures are inserted into the sinking grooves. In this way, the connection stability between the floor-to-ceiling window structure and the building structure is increased, which is used to improve stability through reinforcement method one and further reduce noise. Specifically, the closer the window structure is installed, the less likely the noise is to penetrate.

[0058] Specifically, the panel structure includes a corrugated panel 3 (the corrugated panel is welded in the slot. The design of the corrugated panel structure aims to: increase the stability with the structural adhesive. Specifically, the structural adhesive is filled into the slot, and the gaps between the curved convex parts can also be filled with the structural adhesive, so the sealing treatment effect of this method is better). A number of curved convex parts are integrally formed on the corrugated panel 3; during installation, the corrugated panel 3 is embedded into the sinking grooves at the top and bottom in the window opening and fixed after injecting the structural adhesive.

[0059] Certainly, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the essence of the present invention should also fall within the protection scope of the present invention.
