Abstract
The present invention relates to a high-effective sound-absorbing noise-reducing building material block. It is characterized by that its external form is a cubic brick form, and the brick interior adopts honeycomb type mesopore structure uniform distribution. Said high-effective sound-absorbing noise-reducing building material block is made up by using Portland cement, wood shavings, sand, glue and water according to the mixing ratio of 2:1:1:1:1 through a certain preparation process.
Description
Technical field;
The present invention is a kind of noise reduction sound-absorbing building materials; Particularly relate to a kind of special-purpose absorbing sound and lowering noise building block that can effectively administer railway, the contour noise pollution of highway.
Background technology;
Existing sound insulation and noise reduction material is mainly undertaken by absorption and reflective dual mode.A kind of baffle blanket plate is arranged, and it mainly carries out noise absorption by the fibrofelt goods.Also have a kind of noise reflecting plate, it mainly reflects noise by smooth surface and carries out insulating noise.Though these sound-absorbing sound insulation materialss can carry out noise absorption and isolation, manufacturing cost is higher, and outdoor application life is short, and is damaged easily and aging, installs, maintaining cost height.And railway, highway also do not have special-purpose efficient absorbing sound and lowering noise building block at present.
Summary of the invention;
Content of the present invention provides a kind of efficient absorbing sound and lowering noise building block that can make the noise decline 5-12 decibel of railway and highway.Difficult problem in the environment protection treatings such as it can solve present sound insulation and noise reduction material cost height, the life-span is short, maintaining has high input, effect relative mistake.
A kind of efficient absorbing sound and lowering noise building block, profile are cube brick type, and building block is inner adopts cellular central hole structure evenly to distribute.Efficient sound-deadening and noise-reducing building block has: materials such as silicic acid rock cement, wood flower, the grains of sand, glue, water are formed.
Advantage of the present invention is: the cube structure that (1) has adopted the cellular mesopore of hexagon to form.The cellular central hole structure of this hexagon is present absorbing sound and lowering noise best results design model.(2) efficient absorbing sound and lowering noise building block synthetic materials is with low cost, convenient easily purchases.(3) efficient absorbing sound and lowering noise building block long service life and intensity height.Intensity can be controlled by the consumption of adjusting cement grade and glue.(4) environment friendly and pollution-free, wood flower, wood chips all in the process of manufacture are the rubbish in the woodwork process, and have become the raw material of efficient absorbing sound and lowering noise product in this building block through scientific allocation, have therefore realized twice laid.(5) be not subjected to the influence of natural environmental condition, the wide strong noise of scope of application contaminated area all can use.(6) installation cost is low, and the maintaining expense is almost nil.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
1 of this efficient absorbing sound and lowering noise building block is that monnolithic case is the stereo structure of brick type, is convenient to pile up or tile.The 2nd, the material of forming efficient absorbing sound and lowering noise building block is that (cement+Portland cement+grains of sand+glue+water 2: 1: 1 in proportion: 1: 1) stirs through stamping forming mixture.The 3rd, the hexagonal cellular efficient absorbing sound and lowering noise hole that is evenly distributed.Efficient absorbing sound and lowering noise building block after the punch forming guarantees not ftracture to be certified products.
When using this efficient absorbing sound and lowering noise to build, can adjust the aperture of hexagonal honeycomb, but should in the scope of 2-3cm, can not surpass 3cm according to size, the power of noise.The size of building block can be adjusted according to the size in honeycomb aperture.The connection in each hole is the concrete mix connection by 1cm.
When tiling was used and to be carried out absorbing sound and lowering noise, upwards used in the aperture, vertical wall pile up when using should be with the aperture towards the noise sender to piling up use.It is firm, seamless that the piling up of each piece should guarantee.
Should prevent from the use to stop up, go out the aperture and then can stop up if desired, but stemming length can not surpass 1/5 of noise reduction hole length carry out the aperture of advancing that sound-absorbing makes an uproar towards noise.Can use in wrong hole when piling up.
Claims (1)
1. a railway, the special-purpose absorbing sound and lowering noise building block of highway, profile (1) is a cube brick shape, it is characterized in that: after the mixture (2) that described building block is made up of portland cement, wood flower, the grains of sand, glue, water stirs according to the ratio of 2:1:1:1:1, become inside evenly to adopt the cube brick shape of hexagonal cellular efficient absorbing sound and lowering noise hole (3) structure through punch process, described noise reduction hole aperture 2-3cm, pitch-row is 1cm, and the connection in each hole is to connect by stamping forming five kinds of mixtures of material (2).
