Abstract
The utility model discloses a high-strength sound barrier which comprises concrete plates. A U-shaped accommodating groove is formed in the side, which faces a sound wave incidence direction, of each plate, and perlite surface layers are embedded in the accommodating grooves. The high-strength sound barrier has the advantages that adhesion stress among strengthening portions and the perlite surface layers is high owing to the dead weights of the U-shaped strengthening portions, the high-strength sound barrier is excellent in integral performance, noise reduction performance and durability, free of pollution, high in strength, simple in process, convenient to operate and low in cost, and the like.
Description
Technical field
The utility model relates to a kind of sound insulation materials, is specifically related to a kind of high sound intensity barrier.
Background technology
Along with the continuous enhancing of people's environmental consciousness, problem of noise pollution more and more comes into one's own.In recent years, the fast development of building due to speedway, urban elevated road and urban light rail and the sharply increase of urban automobile quantity, traffic noise problem is on the rise, become affect people's lives the most seriously, one of pollution the most widely.In the measure of various control traffic pollutions, setting up road noise barrier is a kind of effective ways.
Existing sound barrier mainly includes machine sound barrier, metallic sound barrier and inorganic sound barrier three classes.Although organic sound barrier and metallic sound barrier have simple installation, be convenient to maintenance and can scale manufacturing etc. advantage, its cost is high, poor with coordination of landscape, to require high shortcoming be also very obvious to corrosion resistance.Inorganic sound barrier has corrosion-resistant, pollution-free, low cost and other advantages, but there is the defect that sound absorbing capabilities is low in the coagulation great soil group that in existing inorganic sound barrier, intensity is high, and the high pearlite slab of sound absorbing capabilities exists the defect of strength deficiency, the contradiction of therefore coordinating between sound barrier intensity and sound absorbing capabilities becomes urgent problem.
Utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides that a kind of intensity is high, sound absorbing capabilities good, production technology is simple, the high sound intensity barrier of operation and easy construction.
Technical scheme: for solving the problems of the technologies described above, the utility model provides a kind of high sound intensity barrier, comprises concrete plate body, and described plate body has the storage tank of U-shaped towards a side of sound wave incident direction, and described storage tank has been embedded in perlite surface layer.
As preferably, for adjacent plate body when mounted can splice fast securely, one end of described plate body has tenon, and the other end of described plate body has the groove for coordinating with described tenon.
As preferably, in order to strengthen the absorption of high sound intensity barrier surface to noise, the external surface of described perlite surface layer has wedge.
As preferably, in order to strengthen the intensity of plate body, in the concrete of described plate body, be embedded with reinforcing bar.
Beneficial effect: the utility model forms composite construction by the U-shaped perlite surface layer that strengthens part and embed wherein of concrete plate body, by the U-shaped deadweight that strengthens part, make to strengthen between part and perlite surface layer and there is good adhesion stress, overall performance is good, and the sound barrier forming has good anti-acoustic capability, pollution-free, intensity is high, endurance quality is excellent, technique is simple, the advantage such as easy to operate, with low cost.
Accompanying drawing explanation
Fig. 1 is the front view of the high sound intensity barrier of embodiment of the present utility model;
Fig. 2 is the sectional view of Fig. 1;
in figure: 1 plate body, 1-1 storage tank, 2 perlite surface layers, 3 tenons, 4 grooves.
The specific embodiment
Embodiment: a kind of high sound intensity barrier of the present embodiment as depicted in figs. 1 and 2, comprises concrete plate body 1, plate body 1 has the storage tank 1-1 of U-shaped towards a side of sound wave incident direction, and storage tank 1-1 has been embedded in perlite surface layer 2.For adjacent when mounted plate body 1 can splice fast securely, one end of plate body 1 has tenon 3, and the other end of plate body has the groove 4 for coordinating with tenon 3.In order to strengthen the absorption of high sound intensity barrier surface to noise, can wedge be set at the external surface of perlite surface layer 2, in order to strengthen the intensity of plate body 1, can embedded bar in the concrete of plate body 1.
High sound intensity barrier of the present utility model is made in the following ways, then according to component mixed material the vibration moulding of following weight proportion, make perlite surface layer: 80～200 parts of pearls, 280～300 parts of cement, 3～5 parts of waterproof agents, 0.3～0.5 part of fiber, 130～150 parts, water, wherein perlitic particle diameter is 0.63～1.18mm.Then at pearl perlite surface layer outer cladding concrete, form plate body, concrete intensity is more than C30, and perlite surface layer is exposed in a side of plate body.
During use, the pearl perlite surface layer of the high sound intensity barrier of the present embodiment is installed towards sound wave incident direction, and utilized the tenon at plate body two ends and groove to form end to end mounting structure.
Claims (4)
1. a high sound intensity barrier, comprises concrete plate body, it is characterized in that: described plate body has the storage tank of U-shaped towards a side of sound wave incident direction, described storage tank has been embedded in perlite surface layer.
2. a kind of high sound intensity barrier according to claim 1, is characterized in that: one end of described plate body has tenon, and the other end of described plate body has the groove for coordinating with described tenon.
