Description
Technical field
The utility model relates to a kind of noise control technique, particularly relates to a kind of road sound insulation screen barrier that speedway and railway both sides are used for intercepting traffic noise.
Background technology
Noise barrier is a sound insulation facility.In order to block the direct sound between sound source and the recipient, between sound source and recipient, insert a facility, make Acoustic Wave Propagation that a significant additional attenuation be arranged, thereby weaken the interior influence of noise of certain area at recipient place.Noise barrier is mainly used in outdoor.Along with the 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 the development of society, to the intensification of the understanding of the harmfulness of noise, people are increasing for the demand with the noise barrier that can reduce influence of noise.But present noise barrier often uses a large amount of metal structure, and particularly in speedway and railway both sides, the long cost of circuit is high, and management inconvenience.As use metal structure, the maintaining expense is high, causes easily because damaging the stolen normal life cycle that do not reach.
Summary of the invention
The purpose of this utility model is to provide a kind of sound barrier acoustics design standard that meets, and material source is extensive, cheap, that the maintaining expense is low, long service life, manufacturing are quick for installation a kind of road sound insulation screen barrier.
For achieving the above object, technical solution of the present utility model is: a kind of road sound insulation screen barrier, and strengthen structure by main structural member, acoustical board, sound insulation 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 the 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 the noise source direction, the flexible break resistant mortar as bonding agent, cram agent.Structural column is by reinforced concrete prefabricated one-tenth, the structural column side all arranges two grooves, forward is wide groove, by being narrow groove afterwards, the structural column bottom is pedestal bottom plate, and pedestal bottom plate has four installing holes, before and after the structural column and between the pedestal bottom plate stiffener is set all, structural column is installed on four bolts of reinforced concrete plinth by the installing hole of pedestal bottom plate, and the structural column top is provided with the 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

bearing beam is installed on the reinforced concrete plinth by the installing hole of two sides.The 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 the 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 that respectively has by two limits and the bolt at structural column top are installed.The spill tension beam ties up to after acoustical board installs, and the spill with the spill tension beam covers sound barrier and acoustical board downwards again, the spill tension beam the spill moulding not only be conducive to improve structural strength, also be conducive to the protection to sound barrier and acoustical board.Acoustical board uses has the expanded perlite granule of gauze wire cloth to make pearl stone sound absorbing baffle by interior, the acoustical board that perhaps uses sound absorption haydite, expanded vermiculite, these several inorganic sound absorption materials of foaming sound absorption cement to make, long limit two sides of acoustical board are the 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, by little groove, the embedding of small convex groove phase, small convex groove makes progress between two acoustical boards, and little groove is downward.During installation, small convex groove makes progress, and little groove is downward, can prevent effectively that rainwater is detained, and improves the life cycle of acoustical board.Sound barrier uses calcium silicate board, perhaps uses 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 the rear narrow groove by rear and bearing beam parallel docking between two sound barriers.Sound barrier is cut into the sound barrier lath, the phase embedding forms square spacer plate shape stiffening rib behind sound barrier lath fluting, be installed in the sound barrier inboard, width between two grooves of the width of sound barrier lath and structural column side is consistent, forms cavity between the square spacer plate shape stiffening rib of sound barrier lath and acoustical board, the sound barrier.Form the middle sound absorption and insulation structure that contains certain air layer, both be conducive to improve the sound absorbing capabilities of acoustical board, also can improve the sound insulation factor of noise barrier.The flexible break resistant mortar spreads upon between the small convex groove of acoustical board, the little groove as bonding agent, between two sound barrier parallel docking faces, between acoustical board and wide groove, sound barrier and the narrow groove, between the top tongue at spill tension beam and structural column top, acoustical board and the sound barrier top.The flexible break resistant mortar is connected with the overall construction intensity that is beneficial to each member that improves the road sound insulation screen barrier and reduces the slit.The flexible break resistant mortar uses 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 the mortar pulp shooting machine to spray, form bonding and strengthen in that seam is outside, all can effectively cover for the hole of sound barrier and structural column, slit etc.The 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, improves the sound insulation factor that improves the road sound insulation screen barrier.
The beneficial effects of the utility model are: material source is extensive, and is cheap, uses the material do not have recovery value, effectively avoided noise barrier to be damaged stolen and do not reach the deficiency of normal life cycle.Meet simultaneously the acoustics design standard, satisfy the instructions for use of noise barrier, low, the long service life of maintaining expense.。
