Abstract
The utility model discloses a kind of pin-connected panel sound barrier, comprise upper beam, underbeam, column I, column II, backboard, acoustic wall board and cap, described upper beam and the middle groove be provided with through its longitudinal direction of underbeam, column I and column II is cross section " U-shaped " column, and lay respectively at upper beam and underbeam two ends, backboard comprises groove on backboard, groove under groove and backboard in backboard, on backboard, groove outside is positioned at upper beam groove, under backboard, groove is positioned at underbeam groove, the upper and lower side of described acoustic wall board is notch cuttype, and its entirety is positioned at backboard groove, described cap is positioned at the top of column I and column II.This sound barrier adopts inorganic porous sound absorption material as acoustic wall board, solves the existing problem brought because concrete slab is heavy; Acoustic wall board entirety is positioned at backboard inside simultaneously, and mid portion adopts reinforcing bar to run through reinforcing, effectively solves sound absorption body of wall insufficient strength and prevents rainwater from soaking the problem of sound absorption material.
Description
Technical field
The utility model belongs to road or viaduct noise reducing apparatus, is specifically related to a kind of pin-connected panel sound barrier.
Background technology
The fourth-largest environment pollution during noise pollution after water pollutions, atmosphere pollution and solid pollution, traffic noise is then noise pollution the most serious.And along with the raising of the progress of society, the development in city and living standards of the people, urban traffic becomes requisite part in life.Building up of a large amount of high ferros, urban light rail, speedway, the convenience brought, but a lot of expressway is through dense population areas simultaneously, noise will inevitably be brought, very large impact is brought on the live and work of the people, so set up some antinoise barrier shields to be absolutely necessary on side, expressway.
Usually produce between source and noise pollution sensitizing range at noise and sound barrier is set, for intercepting or absorbing noise, reduce sensitizing range noise pollution, reach the requirement of environmental protection.Because concrete slab has good soundproof effect, be more and more employed, but traditional concrete sound barrier panel is heavier, is unfavorable for installation and the transport of shield plates; The sound absorbing capabilities of conventional concrete sound barrier panel is not enough on the other hand, and is difficult to reach the effect effectively abated the noise.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of pin-connected panel sound barrier, and this sound barrier solves problems of the prior art.
In order to solve the problems of the technologies described above, the utility model realizes in the following manner:
A kind of pin-connected panel sound barrier, comprise upper beam, underbeam, column I, column II, backboard, acoustic wall board and cap, the upper beam groove through upper beam longitudinal direction is provided with in the middle of described upper beam, the base contact surface of upper beam groove and upper beam forms platform toward the protruding segment distance in the two ends of upper beam respectively, also the underbeam groove through underbeam longitudinal direction is provided with in the middle of described underbeam, the base contact surface of underbeam groove and underbeam is a protruding segment distance and form platform toward the two ends of underbeam respectively, described column I and column II is the column that cross section is " U-shaped ", column I and column II lays respectively on the platform that upper beam and underbeam two ends stretches out, described backboard comprises groove on backboard, groove under groove and backboard in backboard, on backboard, groove outside is positioned at upper beam groove, under backboard, groove is positioned at underbeam groove, the upper and lower side of described acoustic wall board is forge piece of step type structure, and under its upper end to be arranged on backboard the inner or backboard groove of groove, its lower end to be arranged on backboard groove or groove under backboard, described cap is positioned at the top of column I and column II, for fixing protection column and upper beam.
Described backboard also comprises backboard through hole, described backboard through hole is positioned at the mid portion of backboard, and the column I position corresponding with backboard through hole with column II is equipped with through hole, for running through reinforcing bar, fixing whole back plate and acoustic wall board, backboard through hole is first by resin mortar preservative treatment.
The material of described acoustic wall board is inorganic porous sound absorption material, and its surface is ripple kerve shape.
Compared with prior art, the beneficial effect that the utility model has: the utility model have employed inorganic porous sound absorption material as acoustic wall board, solves the existing problem brought because concrete slab is heavy; Acoustic wall board entirety is positioned at backboard inside simultaneously, by the backboard fixed support of steel work, then enhances the intensity of acoustic wall board, and mid portion adopts reinforcing bar to run through reinforcing on the other hand, more effectively solves the problem of sound absorption body of wall insufficient strength; The body of wall entirety that finally absorbs sound is inserted in the draw-in groove of backboard, effectively prevent rainwater and soaks sound absorption material.
