Abstract
The utility model relates to the technical field of environment-friendly engineering, in particular to a hollow reinforcement filled enhanced sound barrier with oblique holes. The hollow reinforcement filled enhanced sound barrier with the oblique holes is provided with a ceramsite cement composite board, an abutted boss is arranged at the top surface of the composite board, and an abutted groove is arranged at the bottom surface of the composite board. The hollow reinforcement filled enhanced sound barrier is characterized in that a plurality of horizontally arranged cavities are arranged in the middle of the composite board and internally filled with sound-absorption materials; the cavity corresponding to the front side of the composite board is divided into a plurality of regions, and the dense oblique holes are arranged on each region for communicating the cavities; and a steel wire net is pre-arranged on one side in the composite board close to the front side, and a reinforced grid is pre-arranged on one side in the composite board close to the back side. The hollow reinforcement filled enhanced sound barrier has high strength, is filled in hollow parts, has a good absorption effect, lightens the weight, and can be widely used in outdoor engineering facilities such as city roads, rail transit, highways, railways, and the like for eliminating noise.
Description
The (1) technical field: the utility model relates to the environment-friendly engineering technical field, and especially a kind of band inclined hole hollow is filled reinforcing bar and strengthened sound barrier.
The (2) background technology: be the noise nuisance that facilities such as discharge value arterial traffic such as urban track traffic, highway, railway produce, the normal employing mixed the earth plate and intercepted noise.Generally can only reflect noise because mix the earth plate, not possess sound absorption, the effect of improvement is generally bad.Have some mixed earth to form small acicular pores in the hope of acoustically effective once in a while, but sound absorption coefficient is very low through the foaming back, in case and acicular pores by dust and the obstruction of rainwater mixture, just can reduce sound absorption.
The (3) summary of the invention: the purpose of the utility model is exactly the problem that will solve existing highway, the mixed earth plate obstruct of railway employing noise result difference, provides a kind of band inclined hole hollow to fill reinforcing bar and strengthens sound barrier.
The concrete scheme of the utility model is: a kind of band inclined hole hollow is filled reinforcing bar and is strengthened sound barrier; Has the ceramicite cement composite plate; The end face of composite plate is designed with the butt joint boss; The bottom surface is designed with docking recess, it is characterized in that: be designed with some length in the middle of the composite plate to the cavity of arranging, be filled with sound absorption material in the cavity; Be divided into some intervals at the positive corresponding cavity of composite plate, have densely covered inclined hole in each interval and be communicated with cavity; In composite plate, lean on a positive side to preset gauze wire cloth, backrest face one side presets steel grid.
In the utility model, the positive inclined hole collar extension of being opened of said composite plate is 10-15 degree angle and has a down dip, and the single cross-sectional area of inclined hole is not less than 20 square millimeters, in case stopped up by dust.
Positive (one side that has inclined hole) face of noise source, noise got into sound absorption material absorbing and eliminating in the intermediate layer through barrier backplate inclined channel when the utility model was installed; Downward-sloping because of the duct collar extension, can prevent that rainwater from getting into and can not stopped up by dust, the absorbing material that middle cavity is filled fully absorbs the sound that passes the duct; And the middle cavity packing material is lighter, can reduce the quality of composite plate, reduces cost.Preset gauze wire cloth and steel grid in the plate body simultaneously, the resistance to compression bearing strength is high, and the utility model collection sandwich construction is an one, works according to his ability, and sound-absorbing effect obviously improves.
The (4) description of drawings:
Fig. 1 is master's (cuing open) view of the utility model;
Fig. 2 is the left view of the utility model.
Among the figure: the 1-composite plate, 2-docks boss, 3-cavity, 4-sound absorption material, 5-steel grid, 6-docking recess, 7-gauze wire cloth, 8-inclined hole.
The (5) specific embodiment:
Referring to Fig. 1, Fig. 2; The utility model is to adopt haydite and cement to process composite plate 1; The end face of composite plate 1 is designed with butt joint boss 2; The bottom surface is designed with docking recess 6, particularly: be designed with four long cavitys 3 to layout in the middle of the composite plate 1, be filled with sound absorption material 4 (can adopt mineral wool etc.) in the cavity 3; Be divided into four intervals at the positive corresponding cavity of composite plate, have densely covered inclined hole 8 in each interval and be communicated with cavity 3, this inclined hole collar extension is 10-15 degree angle and has a down dip, and the single cross-sectional area of inclined hole is not less than 20 square millimeters; In composite plate 1, lean on a positive side to preset gauze wire cloth 7, backrest face one side presets steel grid 5, promptly constitutes the utility model.
Claims (2)
1. a band inclined hole hollow is filled reinforcing bar enhancing sound barrier; Have the ceramicite cement composite plate, the end face of composite plate is designed with the butt joint boss, and the bottom surface is designed with docking recess; It is characterized in that: be designed with some length in the middle of the composite plate to the cavity of arranging, be filled with sound absorption material in the cavity; Be divided into some intervals at the positive corresponding cavity of composite plate, have densely covered inclined hole in each interval and be communicated with cavity; In composite plate, lean on a positive side to preset gauze wire cloth, backrest face one side presets steel grid.
2. a kind of band inclined hole hollow according to claim 1 is filled reinforcing bar and strengthened sound barrier, it is characterized in that: the positive inclined hole collar extension of being opened of said composite plate is 10-15 degree angle and has a down dip, and the single cross-sectional area of inclined hole is not less than 20 square millimeters.
