Abstract
The utility model relates to a light composite light transmission and sound insulation screen member which comprises a front casing, a sound absorbing body and a cylindrical hollow sealed transparent cavity body, wherein the front casing and the sound absorbing are provided with circular holes and absorbing holes, and the cylindrical hollow sealed transparent cavity body is arranged in each circular hole and is communicated with the front part and the rear part. The utility model is characterized in that the utility model also comprises a rear casing, and two annular flange which are matched are respectively arranged on the circular holes on the relevant positions of the front casing and the rear casing. The front casing and the sound absorbing body behind the front casing can also be made into a prismatic table shape, and then, a metal frame can also be inserted in the surrounding edge of the rear casing. The utility model has the advantages of reasonable structure and flexible, simple and convenient connection and assembly, and thus, the utility model is an ideal member of a sound insulation facility on a road and a viaduct.
Description
The utility model relates to the compound printing opacity acoustic screen of a kind of lightweight member.
The existing disclosed acoustic screen device of ZL00213989.8, adopted the unit member of sound absorber and transparent cavity to be combined into the form of structure of shielding body, though its sound insulation property is good, but sound absorber is generally soft material, be difficult to guarantee the due mechanical strength of screen body in configuration aspects, be difficult to reach the requirement of outdoor service condition; The connection technology that is spliced into the screen body in addition between the unit is also convenient inadequately, causes construction and installation efficient to owe high.
The compound printing opacity acoustic screen of the lightweight member that the purpose of this invention is to provide a kind of mechanical strength height, easy construction.
The utility model is on the basis of existing patent, a back casing that fits with it is set behind sound absorber, a collar flange is all arranged on the circular hole of procapsid and back casing relevant position, make that forward and backward housing is involutory to be inlayed, sound absorber is filled between the two, further also at the embedded unification metal framework of the back casing of above-mentioned plate-like, and square procapsid and sound absorber can be made the terrace with edge shape.
The utility model is rational in infrastructure, but flexible and convenient ground connects assembly unit, particularly can form totally enclosed road sound insulation " path ".Have multiple acoustic characteristic, this is that other acoustic screens are difficult to realize, is the desirable member of the sound insulation facility on road and the viaduct therefore.
Describe the utility model in detail below in conjunction with drawings and Examples.
Fig. 1 basic structure stereogram of the present utility model.When cavity (the right Kong Wei draw transparent)
Fig. 2 exploded sketch of the present utility model.
Fig. 3 structural representation of the present utility model.
Fig. 4 composite assembly schematic diagram of the present utility model.(is example with four members)
Fig. 5 is the side view of Fig. 4.
The utility model includes the procapsid 1 of circular hole 8, sucking 7 and the transparent cavity 5 of column hollow sealing that runs through front and back in sound absorber 2 and the circular hole 8, it is characterized in that it also comprises the back casing 3 that improves sound insulation property, and on the circular hole of the relevant position of procapsid 1 and back casing 3 collar flange 9 is arranged respectively, procapsid 1 and back casing 3 are the involutory relation of inlaying, both form the sandwich construction of acoustics, sound absorber 2 is filled in it, and makes up with both, and the three is assembled into one.Above-mentioned collar flange 9 fuses with procapsid 1 and back casing 3.Consider easy to connect and mechanical strength, also can be at the embedded unification square metal of the surrounding edge of back casing 3 framework 4, this metal framework 4 is a support frame, can be used as again to interconnect between each member to be fixedly coupled part, which is provided with screw 6 and is used for member itself and interconnects fixing using.
As another embodiment, the shape and subsequent the sound absorber 2 of above-mentioned procapsid 1 are made the terrace with edge shape, and make procapsid 1 front and four sides all be furnished with sucking 7, the acoustic characteristic that has perforated plate and tack wedge after making it to make up, with further raising combination property, as Fig. 1, as Fig. 4, Fig. 5.
Above-mentioned procapsid 1 should be used the glass fiber reinforced plastic one-shot forming with back casing 3.Therefore sound absorber 2 is the hydrophobic type expanded perlite product, and it is simple all to have technology, in light weight, and advantages of high strength is assembled as a whole and constructed all very convenient.
