Silencing heat-preservation building block

Abstract

The application discloses a silencing heat-preservation building block and belongs to the field of building materials. The silencing heat-preservation building block consists of an outer wall, a middle wall, side ribs and a middle rib, and is characterized in that the outer wall, the middle wall, the side ribs and the middle rib form two symmetrical vertical small through holes, wherein two symmetrical small trapezoidal notches are formed in the outer wall; two symmetrical large trapezoidal notches are formed in the middle wall; fiber inserts for silencing fill the vertical small through holes; the outer wall, the middle wall and the side ribs on the other side form a second row of vertical large through holes; heat-preservation materials fill the holes. A joint staggered overlap mode is adopted during masonry, and sound easily enters a building block cavity from the two rows of trapezoidal notches of the building block and is gradually weakened and disappears in the building block cavity, so that a wall built by the building blocks has an excellent silencing effect. Meanwhile, the building block has the advantages of light deadweight, simplicity in construction, excellent heat-preservation property and the like and is suitable for building of filled walls with high silencing and heat-preservation requirements.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a sound-absorbing and heat-insulating block. Background technique [0002] The wall is an important line of defense against external noise, and its sound insulation and sound absorption performance is one of the main factors affecting people's life, work and study. As urban noise becomes more and more serious, people have higher and higher requirements for the sound insulation effect of walls. Concrete masonry adopts two methods to provide superior noise control. First, concrete masonry can effectively block the transmission through the air medium. The noise transmission from the past with a wide range of sound frequency; secondly, the concrete masonry can effectively absorb the noise to reduce the noise intensity penetrating the wall. Therefore, it is widely used in enclosure walls, household partition walls in hotel buildings, and even as sound barrier walls along highways. ...

Problems solved by technology

The energy-saving products used for external insulation mainly include EPS board, XPS board, thermal insulation mortar, etc. EPS board and XPS board have good energy-saving effect, but the board has poor fireproof performance, and the construction period is complicated and long. The coefficient is too large, and the thickness of the plastering layer needs to be increased to meet the requirements of energy saving

If the self-insulation system does not adopt a targeted sound-absorbing design, it generally cannot meet the requirements of wall sound-absorbing, which will affect the user's life and privacy. At the same time, the traditional sound-absorbing wall does not have good thermal insulation performance, so it is necessary to find A concrete hollow block with good noise reduction performance and excellent thermal insulation performance
