Abstract
The utility model discloses a bridge segment sound barrier which comprises a guardrail, a plurality of H-shaped steel stand columns, sound absorption and isolation plates, an anti-throwing net, lower sealing plates and barrier top caps. The H-shaped steel stand columns are arranged on the guardrail, the sound absorption and isolation plates are arranged between the adjacent H-shaped steel stand columns, the anti-throwing net is arranged on the back faces of the sound absorption and isolation plates, the lower sealing plates are arranged at the lower ends of the sound absorption and isolation plates, the barrier top caps are arranged at the upper ends of the H-shaped steel stand columns and the upper ends of the sound absorption and isolation plates, supporting plates are arranged at the positions, at the lower ends of the sound absorption and isolation plates, of the lower portions of the H-shaped steel stand columns, and the sound absorption and isolation plates are composed of cement and wood bit sound absorption plates, reinforcing rib meshes arranged in the cement and wood bit sound absorption plates and light sound isolation plates arranged on the back faces of the cement and wood bit sound absorption plates. The bridge segment sound barrier has the advantages of being high in strength, good in stability, good in safety, long in service life and good in sound absorption and isolation effect.
Description
Technical field
The utility model relates to noise control engineering technical field, is specifically related to a kind of bridge section sound barrier.
Background technology
Sound barrier is arranged between sound source and recipient, makes sound wave have a significant additional attenuation, thereby weakens the facility of the influence of noise of recipient place certain area.It is that current domestic employing the most effectively reduces one of measure of traffic noise that road is installed sound barrier, is especially widely used at field sound barriers such as urban viaduct, track traffic, urban express way, high-speed railways.
Urban viaduct is the expansion of the another kind of form of urban traffic, but because most of urban viaduct all adds and builds at original road or road joint, closer to recipient, more of crucial importance to the noise abatement of urban viaduct than original road.
In prior art, need that a kind of intensity is high badly, good stability, long service life, the effective bridge section sound barrier of sound-adsorbing sound-insulating hung.
Summary of the invention
The purpose of this utility model is the deficiency existing in order to overcome prior art, provides that a kind of intensity is high, good stability, long service life, the effective bridge section sound barrier of sound-adsorbing sound-insulating hung.
The utility model is achieved through the following technical solutions: a kind of bridge section sound barrier, comprise guardrail, be arranged at many H shaped steel columns on guardrail, be arranged at the Felt between adjacent two H shaped steel columns, be arranged at the anti-throwing net at the Felt back side, be arranged at the lower shrouding of Felt lower end and be arranged at H shaped steel column and the screen body top cap of Felt upper end, the bottom of described H shaped steel column is provided with gripper shoe in the lower end of described Felt, described Felt is by cement sawdust acoustical board, be arranged at the reinforcement net sheet in cement sawdust acoustical board and be arranged at the cement sawdust acoustical board back side light sound-insulation plate form.
The rearward end of each described H shaped steel column is all connected with adjustment screw, the back side of Felt is provided with adjustment pad, adjust screw and be resisted against on corresponding adjustment pad through the rear end of H shaped steel column, Felt is fixed between two adjacent H shaped steel columns by adjustment screw, adjustment pad and H shaped steel column.
The upper end bending forward of described H shaped steel column, the Felt between the bending part of two adjacent H shaped steel columns and the knuckle place between the Felt of below are provided with airtight and watertight padding layer.
The lower end part of described H shaped steel column is in the back side of described guardrail, and the bottom of described H shaped steel column is connected with described guardrail by screw rod, and the lower end of described H shaped steel column is provided with supporting splint, and described supporting splint is connected with described guardrail by screw rod.
Described light sound-insulation plate is centrifugally glass-wool plate.
The beneficial effects of the utility model are: the utlity model has that intensity is high, good stability, safety are good, long service life, the effective advantage of sound-adsorbing sound-insulating hung.
