Description

Technical Field

[0001] The utility model relates to a heat-insulating and sound-insulating material, in particular to a vacuum structure for construction. Background Art

[0002] In modern life, people's requirements for building materials, on the premise of meeting basic mechanical properties for safe use, will pay more attention to their thermal insulation, sound insulation and other comfort, privacy and green environmental protection performance. Accordingly, they will have more expectations or requirements for sound insulation, noise reduction, energy saving and thermal insulation of house buildings.

[0003] According to the "Social Life Noise Emission Standard" GB22337-2008, the standard values ​​of the five types of urban environmental noise are as follows: Category 0 is for sanatoriums, high-end villa areas, high-end hotel areas, etc., 50 decibels during the day and 40 decibels at night; Category 1 is the standard applicable to areas dominated by residences and cultural and educational institutions, 55 decibels during the day and 45 decibels at night; Category 2 is applicable to mixed residential, commercial and industrial areas, 60 decibels during the day and 50 decibels at night; Category 3 is applicable to industrial areas, 65 decibels during the day and 55 decibels at night; Category 4 is applicable to areas on both sides of urban road traffic arteries, etc., 70 decibels during the day and 55 decibels at night. 40-60 decibels is the standard for ordinary indoor conversations. Exceeding 60-70 decibels will damage nerves, and higher will damage nerve cells and even hearing loss. In fact, noise has become a major environmental pollution in modern urban life, and the acoustic environment of buildings has received more and more attention and attention.

[0004] At present, noise control in buildings is mostly carried out through two different noise reduction methods, namely, sound insulation and sound absorption. Among them, sound insulation usually refers to the use of certain items, namely, sound insulation materials, to isolate, separate, etc., that is, to block the sound outside through sound insulation materials; therefore, for sound insulation materials, the purpose is to reduce the transmitted sound energy and block the propagation of sound, and usually requires that the material is heavy and dense. Commonly used sound insulation materials, such as steel plates, lead plates, concrete walls, brick walls and other materials. It is generally believed that in terms of noise reduction effect, using sound insulation materials or sound insulation structures to isolate noise is better than using sound absorbing materials to absorb sound.

[0005] Modern buildings often have dozens of floors. Existing sound insulation materials generally have problems such as heavy weight, inconvenient on-site construction, and long construction period.

[0006] On the other hand, with the requirements of countries around the world for energy conservation and emission reduction, the application of thermal insulation materials has become more and more extensive, and is increasingly showing a development trend of green environmental protection, multi-functionality, simple and easy construction, and intelligent application. Summary of the invention

[0007] In view of the limitations of the prior art and people's demand for sound insulation and heat preservation effects of buildings, the utility model discloses a vacuum structure for buildings based on acoustic and thermal principles, which is lightweight, practical, cheap to construct, and has excellent sound insulation and heat preservation effects.

[0008] The technical solution of the utility model is achieved in this way:

[0009] A vacuum structure for construction includes a frame, a vacuum cavity and a built-in bracket, wherein the frame is a vacuum sealing structure made of resin material; the built-in bracket adopts a grid plate made of resin material; the frame can be evacuated to form the vacuum cavity by installing a one-way valve on the frame, and the built-in bracket divides the vacuum cavity into a plurality of small chambers in the frame.

[0010] Specifically, the enclosure frame includes a lower base, an upper cover and a structural unit A;

[0011] The structural unit A includes a frame and a circumferential outer edge integrally formed with the frame; or also includes a sealing groove and a corresponding seal for sealing the position where the upper cover and / or the lower bottom are connected to the structural unit A; the sealing element includes a sealing ring or a sealing strip, etc., the sealing groove is arranged between the outer edge and the frame, and the sealing element is built into the sealing groove.

[0012] Further, the structural unit A can be integrally formed or fixedly connected with the lower base to form a structural unit B. Then, the grille plate is integrally formed or fixedly connected with the structural unit B to form a structural unit C1; or, the grille plate is integrally formed or fixedly connected with the upper cover to form a structural unit C2.

[0013] Alternatively, the grid plate and the structural unit A are integrally formed or fixedly connected to form a structural unit C3.

[0014] When the surrounding frame is a sealed structure formed by assembling and connecting the structural unit A and the upper cover and / or the lower bottom after being separately processed and formed, in order to ensure accurate installation and positioning of the structural unit A and the upper cover and / or the lower bottom, a positioning structure is provided on the structural unit A, and corresponding positioning structures are provided at corresponding positions on the upper cover and / or the lower bottom.

[0015] In order to facilitate vacuuming, a passage for connecting the two adjacent small chambers is provided on the grid plate between the two adjacent small chambers, such as a through hole or a notch, usually with a diameter of less than 2 mm.

[0016] According to the principles of acoustics, sound is a wave produced by the vibration of matter, and it needs to be transmitted through a medium such as air to be heard; according to the principles of thermal conductivity, for heat conduction, both convection heat transfer and contact heat transfer require a heat transfer medium, and vacuum insulation is achieved by removing the air medium. Based on the above-mentioned natural principles, the utility model utilizes the sound insulation and heat insulation characteristics of vacuum, based on market demand, fully considers on-site construction needs, material properties and process performance, and innovates in practice. Compared with the prior art, the utility model is designed and manufactured using natural principles to meet the needs of modern people for green insulation and sound insulation and noise reduction in private or public indoor spaces, and has the following outstanding features:

[0017] 1. Ensure the consistency, high efficiency and high quality of on-site construction. The vacuum structure of the utility model can be manufactured as a whole in the factory according to certain specifications, and can be directly fixed and installed at the construction site, such as by using expansion nails to nail it into the wall of the building to achieve a seamless fixed connection. Compared with some existing thermal insulation materials that require on-site mixing and laying of the adhesive mixture, and then wait for it to solidify to form a sealing layer, the on-site construction of the utility model is obviously more convenient and efficient, significantly shortening the construction period, and is more conducive to ensuring the consistency and high quality of construction.

[0018] 2. The advantage of light weight is obvious. It is especially suitable for the insulation and sound insulation needs of modern high-rise and super high-rise buildings, greatly reducing the weight of the building walls.

[0019] 3. The structure is scientific and reasonable, with outstanding thermal insulation and sound insulation effects; the production process is simple; at the same time, the raw materials are locally sourced, and 100% domestic raw materials can be used. The supply chain is stable and conducive to the full development of the domestic economy.

[0020] At the same time, compared with the commonly used porous materials, such as nanoporous silicon fiberboard, rock wool board, glass fiberboard and non-woven felt made of glass fiber, practice has shown that resin grid plate has better support effect as a built-in bracket, and there will be no obvious shrinkage and deformation problems after vacuuming, thus ensuring the accuracy and consistency of measurement, processing and on-site construction dimensions, and further ensuring the convenience and progress of on-site construction.

[0021] In short, the utility model has outstanding energy-saving and noise reduction effects, high quality and low price, good workmanship, and is especially convenient for on-site construction. It can be widely used as thermal insulation and sound insulation building materials and building structures in various civil and public spaces or places including high-rise residential buildings, hotels, libraries, conference halls, hospitals, sanatoriums, etc., and has a broad market space.
