Abstract
The invention discloses a high-strength sound barrier which comprises a concrete slab, wherein a U-shaped accommodating groove is formed in one side, in the incidence direction of a sound wave, of the concrete slab, and a perlite surface layer is embedded in the accommodating groove. According to the invention, the dead load of the U-shaped enhanced part is adopted to enable that excellent cohesive force is formed between the enhanced part and the perlite surface layer, the integral performance is excellent, and the high-strength sound barrier has the advantages of excellent noise reduction performance, zero pollution, high strength, excellent durability, simple technology, convenience in operation, low cost and the like.
Description
Technical field
The present invention relates to a kind of sound insulation materials, be 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, the traffic noise problem is on the rise, and having become affect that people's lives are the most serious, 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 but organic sound barrier and metallic sound barrier have simple installation, are convenient to the advantages such as maintenance and scale manufacturing, its cost is high, poor with coordination of landscape, the demanding shortcoming of corrosion resistance is also very obvious.Inorganic sound barrier has corrosion-resistant, pollution-free, low cost and other advantages, but there is the low defective of sound absorbing capabilities in the coagulation great soil group that in existing inorganic sound barrier, intensity is high, and there is the defective of strength deficiency in the high pearlite slab of sound absorbing capabilities, and the contradiction of therefore coordinating between sound barrier intensity and sound absorbing capabilities becomes urgent problem.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention 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 invention provides a kind of high sound intensity barrier, comprise the concrete plate body, 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 the perlite surface layer.
As preferably, for adjacent plate body when mounted can splice fast securely, an end of described plate body has tenon, and the other end of described plate body has the groove that coordinates for described tenon.
As preferably, in order to strengthen the high sound intensity barrier surface to the absorption of noise, the external surface of described perlite surface layer has wedge.
As preferably, in order to strengthen the intensity of plate body, be embedded with reinforcing bar in the concrete of described plate body.
The perlite surface layer of high sound intensity barrier of the present invention comprises the following component according to weight proportion: 80～200 parts of perlites, 280～300 parts of cement, 3～5 parts of waterproof agents, 0.3～0.5 part of fiber, 130～150 parts, water.
As preferably, described perlitic particle diameter is 0.63～1.18mm.
Beneficial effect: the present invention forms composite construction by the U-shaped perlite surface layer that strengthens part and embed wherein of concrete plate body, make to strengthen between part and perlite surface layer by the U-shaped deadweight that strengthens part and have good adhesion stress, overall performance is good, and the sound barrier that forms 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.
Description of drawings
Fig. 1 is the front view of the high sound intensity barrier of embodiments of the invention;
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 comprises concrete plate body 1 as depicted in figs. 1 and 2, and 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, an end of plate body 1 has tenon 3, and the other end of plate body has the groove 4 that coordinates for tenon 3.In order to strengthen the high sound intensity barrier surface to the absorption of 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 invention is made in the following ways, then according to component mixed material and the vibration moulding of following weight proportion, make the 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 form plate body at pearl perlite surface layer outer cladding concrete, concrete intensity is more than C30, and the 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 the sound wave incident direction, and utilized tenon and the groove at plate body two ends to form end to end mounting structure.
