The main structural component is formed by reinforced concrete bases, structural columns, force bearing beams and concave tension beams, the sound absorption plates are arranged in the direction close to a noise source, the sound insulation reinforcement structure is formed by sound insulation plates and square insulation plate shape stiffening ribs and is arranged in the direction opposite to the noise source, and flexible anti-crack mortar is used as adhesives and filling agents. The structural columns, the force bearing beams and the concave tension beams are all prefabricated by reinforced concrete. The road sound insulation barrier has the advantages of being wide in material sources and low in manufacturing cost, and meanwhile accords with acoustic design standards, the use requirement for the sound insulation barrier is met, maintenance cost is low, and the service life is long.
Description
Technical field
The present invention relates to a kind of noise control technique, particularly relate to speedway and railway both sides for intercepting a kind of road sound insulation screen barrier of traffic noise.
Background technology
Noise barrier is a sound insulation facility.In order to block the direct sound between sound source and recipient, between sound source and recipient, insert a facility, make Acoustic Wave Propagation have a significant additional attenuation, thereby weaken the influence of noise in the certain area at recipient place.Noise barrier is mainly used in outdoor.Along with highway traffic noise pollution is day by day serious, adopt in a large number various forms of noise barriers to reduce traffic noise.
Along with social development, the intensification to the understanding of the harmfulness of noise, people are increasing for the demand with the noise barrier that can reduce influence of noise.But current noise barrier, is often used a large amount of metal structure, particularly in speedway and railway both sides, the long cost of circuit is high, and management inconvenience.As use metal structure, maintaining expense is high, easily causes because damaging the stolen normal life cycle that do not reach.
Summary of the invention
The object of the present invention is to provide a kind of sound barrier acoustics design standard that meets, material source is extensive, cheap, maintaining expense is low, long service life, manufacture are quick for installation a kind of road sound insulation screen barrier.
For achieving the above object, technical solution of the present invention is: a kind of road sound insulation screen barrier, and by main structural member, acoustical board, sound insulation, strengthen structure and form.Main structural member is comprised of reinforced concrete plinth, structural column, bearing beam and spill tension beam, acoustical board is arranged on by noise source direction, sound insulation is strengthened structure and is comprised of sound barrier, square spacer plate shape stiffening rib, be arranged on back to noise source direction, flexible break resistant mortar as bonding agent, cram agent.Structural column is by reinforced concrete prefabricated one-tenth, structural column side all arranges two grooves, forward is wide groove, leaning on rear is narrow groove, and structural column bottom is pedestal bottom plate, and pedestal bottom plate has four installing holes, before and after structural column and between pedestal bottom plate, stiffener is all set, structural column is arranged on four bolts of reinforced concrete plinth by the installing hole of pedestal bottom plate, and structural column top is provided with top tongue, two erection bolts on the tongue of top.The stiffener of structural column can improve structural column wind load holding capacity.Bearing beam is by reinforced concrete prefabricated one-tenth, and bearing beam side is corresponding with structural column, and forward have a wide groove, has a narrow groove after leaning on, and bearing beam is arranged on reinforced concrete plinth by the installing hole of two sides.Spill tension beam is by reinforced concrete prefabricated one-tenth, the installing hole that two limits respectively have, the insied width of spill tension beam is consistent with the outer width of top tongue at structural column top, also consistent with the total outer width of two grooves of structural column side, the top tongue of spill tension beam embedded structure column top, the installing hole respectively having by two limits and the bolt at structural column top are installed.Spill tension beam ties up to after acoustical board installs, then the spill of spill tension beam is covered sound barrier and acoustical board downwards, spill tension beam spill moulding be not only conducive to improve structural strength, be also conducive to the protection to sound barrier and acoustical board.Acoustical board is used has the expanded perlite granule of gauze wire cloth to make pearl stone sound absorbing baffle by interior, the acoustical board that also can use the inorganic sound absorption materials such as sound absorption haydite, expanded vermiculite, foaming sound absorption cement to make, long limit two sides of acoustical board are plane, and minor face two sides are provided with little groove, small convex groove.In the wide groove of acoustical board embedded structure post and bearing beam side, between two acoustical boards, by little groove, the embedding of small convex groove phase, upwards, little groove is downward for small convex groove.During installation, upwards, little groove is downward for small convex groove, can effectively prevent that rainwater is detained, and improves the life cycle of acoustical board.Sound barrier is used calcium silicate board, also can use weather resistance good, and the light sound-insulation plate that the inorganic material that mechanical strength is high is made leans on sound barrier embedded structure post side in rear narrow groove by rear and bearing beam parallel docking between two sound barriers.Sound barrier is cut into sound barrier lath, after sound barrier lath fluting, phase embedding forms square spacer plate shape stiffening rib, be arranged on sound barrier inner side, width between two grooves of the width of sound barrier lath and structural column side is consistent, between the square spacer plate shape stiffening rib of sound barrier lath and acoustical board, sound barrier, forms cavity.Form the middle sound absorption and insulation structure that contains certain air layer, be both conducive to improve the sound absorbing capabilities of acoustical board, also can improve the sound insulation factor of noise barrier.Flexible break resistant mortar spreads upon between the small convex groove of acoustical board, little groove as bonding agent, between two sound barrier parallel docking faces, between acoustical board and wide groove, sound barrier and narrow groove, between the top tongue at spill tension beam and structural column top, acoustical board and sound barrier top.Flexible break resistant mortar is connected with and is beneficial to the overall construction intensity of each member that improves road sound insulation screen barrier and reduces gap.Flexible break resistant mortar is used flush coater to spray between the seam of the narrow groove of sound barrier and structural column and bearing beam side, between the sound barrier lath of phase embedding, between the seam of dividing plate shape stiffening rib and sound barrier, structural column and bearing beam side as cramming agent.Use mortar pulp shooting machine to spray, form bonding and strengthen seam is outside, for the hole of sound barrier and structural column, gap etc., all can effectively cover.Flexible break resistant mortar has stronger adhesion strength and weather resisteant, can with sound barrier, dividing plate shape stiffening rib and main structural member strong bonded, improve structural strength and the ant wind load ability of sound barrier, acoustical board.And the flexible break resistant mortar of spraying has certain sound insulation property, can prevent the noise leakage of seam crossing, improve the sound insulation factor that improves road sound insulation screen barrier.
The invention has the beneficial effects as follows: material source is extensive, cheap, use the material there is no recovery value, effectively avoided noise barrier to be damaged stolen and do not reached the deficiency of normal life cycle.Meet acoustics design standard simultaneously, meet the instructions for use of noise barrier, maintaining expense is low, long service life.
