Abstract

The utility model discloses a noise-proof screen structure used for overhead roads, highways, railway lines and boundaries of factory districts, which comprises an H-steel upright post, an upright post connecting piece and an anti-falling device, wherein, the upright post connecting piece is composed of a flange plate welded at the bottom of the H-steel upright post, and a flange plate and a flange bolt which are pre-buried on the top of an anti-punching wall; a flexible wire rope is connected with a sound-absorbing screen plate in series to be anchored into the anti-falling device. The sound-absorbing screen plate is composed of a face plate, a back plate, a side plate and sound-absorbing materials between the face plate and the back plate, the face plate is a louver-declining type slit, the back plate is provided with a horizontal press groove, a cavity is arranged between the back plate and the sound-absorbing materials, and the face plate, the back plate and the side plate are tightly combined.

Description

The Noise-proof screen structure
The utility model relates to a kind of device that reduces noise transmission, is a kind of sound absorption class Noise-proof screen structure specifically.
Sound arrester is existing to be used, but generally is used for indoorly, and it is along the line to be used for elevated road, speedway and railway, for the antinoise technology in this sensitivity location of protection do not see have open.
The purpose of this utility model is to provide a kind of economy and durability; Noise-proof screen structure easily is installed; along the line and the big border, factory district of some noise applicable to elevated road, speedway, railway; for the living environment in responsive locations such as the contiguous dwelling house of protection, hospital, school, thereby alleviate influence of noise pollution.
To achieve these goals, the utility model adopts following technical scheme: a kind of Noise-proof screen structure, comprise the H steel post, column connector and anti-drop device, the column connector reaches the flanged plate and the flange bolt that are embedded in the anti-scour wall top in advance by the flanged plate that is welded on H steel post bottom and forms, the anchoring of flexible wire ropes series connection sound absorption screen board constitutes anti-drop device, it is characterized in that: described sound absorption screen board is by panel, backboard, sound absorption material between side plate and panel and backboard is formed, this panel cracks for the louver dipping type, this backboard is provided with horizontal indent, leave cavity between this backboard and this sound absorption material, this panel, this backboard and this side plate are combined closely.
Good effect of the present utility model is: utilize the sound diffraction principle between noise source and sensitive target, in the side formation " sound shadow region " of barrier, thereby alleviate influence of noise pollution, play the effect of protection environment adjacent; The utility model maximum characteristics structurally are with reliability, safety and good ingenious combination of noise control performance, through careful research, adopt the unique technique measure, this Noise-proof screen is stood upright on urban elevated road, whole tall and straight, bright and clean, straight, bear the collision of the invasion and attack of high wind heavy rain and contingency and do not have disconnectedly attack, broken, the worry fallen; The utility model does not need ordinary maintenance, economy and durability, and it is convenient to install, mutually well matched with modernized city.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a preferred embodiment sound absorption of a utility model screen board generalized section;
Fig. 2 is a preferred embodiment H of a utility model steel post generalized section.
See also illustrated in figures 1 and 2ly, the utility model is made up of sound absorption screen board 10, H steel post 20, anti-drop device (not shown) and column connector (not shown).The panel 11 usefulness color steel sheets of sound absorption screen board are made, and adopt the louvre form of cracking, and are downward-sloping in case go up the rainwater infiltration, and the size of its percent opening can have influence on the sound absorption frequency characteristic and the sound absorption coefficient of screen, and the double buckle combination is arranged before the panel.The backboard 12 of sound absorption screen board adopts the certain rigidity of tool and has the material of enough sound insulation factors to make, its middle part is provided with indent 13, both attenuate materials, increase rigidity, sound absorption material 14 between supporting faceplate and the backboard again simultaneously, make sound absorption material reserve suitable cavity 15 behind, to improve medium and low frequency scope acoustically effective.Panel, backboard combine with side plate closely, and adopt ramp structure, all splice with certain slope with end face 17 in the bottom surface 16 of screen board up and down, both can prevent leak-stopping sound, can avoid ponding again.
Column of the present utility model 20 adopts the H shaped steel, and this H shaped steel column is high as when adopting 3m, web 21 high 130mm, wing plate 22 wide 180mm, thickness of slab 8mm.
For the control screen board breaks away from the column edge of a wing, unlikely individual plates drops, and the utility model is provided with anti-falling device, and this device is the anchoring of flexible wire ropes series connection sound absorption screen board.This device roughly is divided into two kinds, and a kind of column that is used for props up in the anti-scour wall outside, and promptly the two ends screen board all passes steel cable, and the wire rope upper and lower side is fixed with special anchor bolt; To be wire rope pass from the top flange preformed hole of next piece screen board another kind, passes through column web bottom again, upwards wears each piece screen board of connection, fixes to shielding screw, and this kind form is used for column more and directly props up above anti-scour wall.
The utility model column connector is pre-buried flanged plate and flange bolt.Put pre-buried flanged plate earlier in the anti-scour wall top, locate simultaneously in the anti-scour wall construction; The column that is welded with flanged plate is installed on it uses bolt, it is good to reach structural integrity, and material uses rationally, and outward appearance is neatly straight.
The utility model monnolithic case can be divided into upright enclosure wall formula, folded plate type, curved arc formula, totally enclosed type etc. by requirement of engineering.Each screen board and column embedding are pressed with fixture of the spring, and no exposed screws, screen board splice up and down and locate to be pasted with rubber packing, and column and screen board all are in series with the wire rope of latent fraud.All these measures are all to prevent that the part from rocking, leakage sound, ensure the durable in use safe and reliable of engineering integral body to greatest extent.

Claims (3)
