Abstract

The utility model provides a sound insulation absorbing protective screen, comprising a frame that is provided with a sound absorbing material. A multi-pore face plate is mounted on one side of the frame that absorbs the sound and a solid plate is mounted on another side relatively. A concave and a convex sealing plate that matches each other are provided respectively on both ends superposed of the protective screen of the frame. In the utility model, a concave and a convex sealing plate that matches each other are provided respectively on both ends superposed of the protective screen of the frame. The sealing plates can automatically position and are compactly combined, which overcomes the weak link of sound insulation and improves the sound isolation effect efficiently.

Description

A kind of sound absorbing-insulating barrier

Technical field

The utility model relates to noise pollution Prevention Technique field, relates in particular to a kind of sound absorbing-insulating barrier.

Background technology

Along with quickening of urbanization process, the raising of living standards of the people, increasing high buildings and large mansions are installed air system, source pump and roof cooling tower on the roof, and the Urban Commercial House soil is as scarce resource, the plot ratio in each commercial residential buildings is more and more higher, and influence each other is increasing.Near close roof is equipped with the building of air system, source pump and roof cooling tower; noise can not reach corresponding control criterion; the dwelling house resident is subjected to its noise effect very serious, even reach standard, can not satisfy the needed indoor acoustic environment of people's normal activity.

In addition, along with the continuous increase of urban motor vehicle, China's expressway increasing, the traffic noise pollution trend that disturbs residents increases the weight of, and becomes the emphasis environmental problem in influence quality of residents'life along the line and body and mind Jiankang.

At present, for alleviating this type of noise pollution problem that disturbs residents, the method for current common employing is that the installation sound absorbing-insulating barrier is set.Under current technical conditions, sound absorbing-insulating barrier adopts aluminium sheet punching or aluminium sheet louvered structure or foamed aluminium board unitized construction usually.The sound absorbing-insulating barrier of above-mentioned three kinds of structures is controlled weak effect to noise, the manufacturing cost costliness.

Summary of the invention

The utility model provide a kind of economic and practical, easy for installation, to the effective sound absorbing-insulating barrier of noise control.

A kind of sound absorbing-insulating barrier comprises framework, is provided with acoustic absorbant in the framework, and a side of framework sound absorption is equipped with the porous protection slab, and relative opposite side is equipped with solid slab, and the concave, convex shape shrouding that cooperatively interacts is equipped with at the two ends that barrier joins on the framework respectively.

On the framework fixedly the both sides of barrier Z type shrouding is housed, be convenient to the installation and removal of barrier.

Acoustic absorbant coats membraneous material outward, prevents that acoustic absorbant from making moist, influencing acoustically effective.

Framework is made of C shape keel, and C shape keel pin down mutually, just as many little C font girder steels, can disperse the pressure from each face, and when guaranteeing that framework is subjected to pressure than hard intensity, barrier still can keep flatness preferably.

The sound absorbing-insulating barrier that the utility model provides, the concave, convex shape shrouding that cooperatively interacts is equipped with at the two ends that barrier is connected on framework, can locate automatically during installation, concave, convex shape shrouding is in conjunction with tight, overcome the weak link of sound insulation, effectively improved defening effect, also had simultaneously and prevent the seeping phenomenon that exists when barrier is used preferably.

Description of drawings

Fig. 2 is the A-A sectional view of barrier shown in Figure 1;

Fig. 3 is the B-B sectional view of barrier shown in Figure 1.

Embodiment

As Fig. 1, Fig. 2 and shown in Figure 3, a kind of sound absorbing-insulating barrier comprises framework 1, and framework 1 is a rectangular parallelepiped, be made of C shape keel, keel are formed from steel, and also can be made by timber, aluminium alloy etc., be provided with acoustic absorbant 5 in the framework 1, acoustic absorbant 5 is a centrifugally glass-wool, also available super glass wool; The acoustic absorbant 5 outer films that coat, film is selected the PVF film for use, also can select alkali-free hydrophobic glass cloth for use.

One side of framework 1 sound absorption is equipped with porous protection slab 3, and porous protection slab 3 sizes are consistent with the face size that contacts with framework 1, can select the FC orifice plate for use, also can select steel orifice plate or aluminium orifice plate for use; Relative opposite side is equipped with solid slab 2, and size is consistent with porous protection slab 3, can select the FC plate for use, also can select steel plate or aluminium sheet for use.

Spill shrouding 7 and the convex shrouding 6 that matches is equipped with at the superimposed two ends of barrier respectively on the framework 1, notch plate 7 is a flat board, central dip becomes the V font, and the edge part becomes 90 degree bendings, is buckled in the end of framework 1, convex shrouding 6 also is a flat board, central protuberance becomes inverted v-shaped, and the edge part becomes 90 degree bendings, is buckled in the end of framework 1 other end, spill shrouding 7 and convex shrouding 6 are difficult for loosening in conjunction with closely.

Z-shaped shrouding 8 is equipped with in the both sides that barrier is fixed in column on the framework 1, and Z-shaped shrouding 8 edges become 90 degree bendings, is buckled in the side of framework 1, in conjunction with tight.

When sound absorbing-insulating barrier was installed, sound absorbing-insulating barrier was clipped between two type columns, and Z-shaped shrouding 8 cooperates with corner angle of type column, installed closely, was pressed on the column sound absorbing-insulating barrier fixing with steel plate and screw rod then.
