Description

Sound-proof barrier permeates water

Technical Field

The invention relates to the technical field of traffic environmental protection facilities. In particular to a permeable sound-proof screen which is mainly used for roads and bridges.

Background

With the increasingly frequent social and economic activities of cities in China, the urban traffic demand is rapidly increased, and particularly, large-scale traffic projects such as overpasses, viaducts and the like continuously appear in urban traffic systems. The overpass and the viaduct relieve traffic pressure to a great extent, but the noise problem brought by the overpass and the viaduct is increasingly prominent.

In order to solve the noise problem, sound barriers with the height of 2-3 m are arranged on two sides of a road. However, such sound barriers do not currently perform noise treatment on the inner side of the protective wall and the lower part of the sound barrier, but only perform sound insulation blocking on a gap between the protective wall and the sound barrier. In addition, in order to reduce noise to the maximum extent, the bottom of the water tank is also provided with a sound barrier unit plate, and both methods can cause unsmooth drainage and breeding of algae.

The invention aims to solve the technical problem of providing a water-permeable sound-proof screen aiming at the gap in the background technology, which replaces the existing plugging method to solve the problem of sound-proof plugging of the gap between a sound barrier and a protective wall.

Disclosure of Invention

A permeable sound-insulating screen is characterized by comprising an upper clamp, a permeable plate, a honeycomb aluminum pore plate, a back plate and a lower clamp; the upper clamp is clamped at the upper end of the long side of the honeycomb aluminum pore plate, and the lower clamp is clamped at the lower end of the long side of the honeycomb aluminum pore plate; go up checkpost, honeycomb aluminium orifice plate and lower checkpost setting in the inslot of porous disk, backplate and porous disk riveting.

The porous disk is the shaping of bending for steel or aluminum product suppression, and the porous disk upper end sets up the arch, and the porous disk lower extreme sets up the recess, and porous disk outside panel is equipped with the tripe hole of permeating water that outwards stretches out.

The backplate is steel or aluminum product suppression shaping of bending, and the backplate upper end is equipped with the arch, and the backplate lower extreme is equipped with the crotch, and there is the outlet backplate bottom, and the porous disk cooperation. .

The honeycomb aluminum hole plate consists of perforated face plates at two sides, a perforated back plate and a middle honeycomb core; the perforated face plate and the rear plate are uniformly provided with small holes, and the maximum perforation rate is less than 30%.

The invention perforates the face plate and the back plate, so that gas and water in the plate can flow freely; the structure can not deform when expanding with heat and contracting with cold, and extremely high flatness can be ensured.

Perforation panel and back plate adopt with the same material of honeycomb core, through control perforation aperture, pitch-row, and can change the perforation rate according to customer operation requirement, perforation aperture generally chooses for use in the in 2.0mm, in 2.5mm, in 3.0mm specification.

The honeycomb core is a hexagonal aluminum honeycomb core, the inner layer is a specially-made hexagonal aluminum honeycomb, and the hexagonal aluminum honeycomb core is used as a core plate adhered to the sandwich structure and bears pressure in the tangential direction. The dense honeycombs which are mutually drawn are like a plurality of small I-shaped beams, and can disperse and bear pressure from the direction of the panel, so that the panel is uniformly stressed, and the panel can still keep high flatness in a large area.

The honeycomb material has the excellent performances of high wind pressure resistance, shock absorption, sound insulation, heat preservation, flame retardance, high specific strength and the like.

Detailed Description

As shown in fig. 1, 2 and 3, a water-permeable sound-proof screen has a length, width and thickness of 1960 mm, 500 mm and 140mm, and is composed of an upper clip 1, a water-permeable plate 2, a honeycomb aluminum pore plate 3, a back plate 4 and a lower clip 5.

The upper clamp 1 is clamped at the upper end of the long edge of the honeycomb aluminum pore plate 3, and the lower clamp 5 is clamped at the lower end of the long edge of the honeycomb aluminum pore plate 3; go up checkpost 1, honeycomb aluminum pore plate 3 and lower checkpost 5 and put into porous disk 2, porous disk 2 is in the same place with 4 buckles of backplate.

As shown in fig. 4 and 5, the permeable plate is a profiled bent thin plate member made of aluminum with the thickness of 1.5mm, concave-convex grooves are arranged at the upper part and the lower part, and the panel is provided with upward-opened shutter permeable holes; water in the thread can be permeated.

As shown in fig. 6, the back plate is a 1.5mm thick aluminum pressed bent thin plate member, which has a convex groove on it and a hook on it, and the bottom of the panel has a drainage port to match with the inner hole plate; accumulated water penetrating through the honeycomb aluminum pore plate can be discharged.
