Abstract

The utility model discloses a metal mesh plate. Sawtooth-shaped surfaces with concave-convex structures are arranged on the metal plate at intervals; trapezoid surfaces are arranged on the back surface of a tooth at intervals; an inwardly concave prism with a transition round angle is arranged between the two trapezoid surfaces; the bottom line of the prism is separated from the metal plate to form a triangular through hole with a transition round angle; and a prismatic channel with a transition round angle is formed by a space between the triangular through hole and the inner concave surface of the prism. The utility model not only solves the defects that the sound absorbing materials are moistened, sound waves are not easy to attenuate, and a combined sound absorbing plate with the sound absorbing effect is influenced, but also greatly simplifies the manufacture of a sound absorbing screen, improves the work efficiency, saves the material used for the sound absorbing screen by 80 percent, and reduces the construction cost by above 50 percent, thereby achieving the purpose of reducing the noise and protecting the environment.

Description

A kind of metal otter board

One, technical field:

A kind of metal otter board of the utility model, what relate to is metal otter board design and manufacturing technology field, is applied to prevent dust, absorbs sound, filters and decorates.

Two, background technology:

At present, domestic used abatvoix class is numerous, generally all adopts porose metallic plate and combination of materials formula acoustic board that can noise reduction, or adopts the wooden sound-absorbing material of being with fibre property that waits.The structure relative complex is made moist easily, and fire protecting performance and weatherability are poor, is not suitable for all-environment requirement, has directly influenced acoustically effective, has restricted this type of sound-absorbing material and has used.

Three, summary of the invention:

The purpose of this utility model is to overcome above-mentioned defective, by to the punching press of metallic plate or roll worker's technology, designs and a kind ofly can solve requirements such as sound-absorbing material makes moist, fire prevention, does not influence a kind of metal otter board of sound-absorbing effect again.It is characterized in that: the surface that is interval with the zigzag concaveconvex structure on the metallic plate, back of tooth spaced surface is provided with trapezoidal faces, be provided with the prismatic that indent has angle, transition garden between two trapezoidal faces, prismatic bottom line and metallic plate break away from, formation has the triangle through hole at angle, transition garden, triangle through hole and prismatic inner concave space form the prismatic passage with angle, transition garden, and the back of tooth of described zigzag relief structured surface and the angle α angle between crown are in 48～52 ° of scopes.The positive effect of implementing after this technology is: both solved sound-absorbing material and made moist, sound wave is not easy decay, influences the defective of the combined type acoustic board of acoustically effective; The gobo manufacturing is greatly simplified, has improved operating efficiency, gobo has saved 80% with material, reduces construction costs more than 50%; Reach the reduction noise, the purpose of protection environment.

Four, description of drawings:

Fig. 1 is a main TV structure schematic diagram of the present utility model;

Fig. 2 looks the sectional structure schematic diagram for a left side of the present utility model;

Fig. 3 is the structural representation of embodiment sound barrier of the present utility model;

Wherein, 1-metal otter board, 2-keel, 3-supporting frame, 4-trapezoidal faces, 5-prismatic, 6-triangle through hole, the 7-back of tooth, 8-prismatic passage, 9-crown;

Five, the specific embodiment:

Following with reference to accompanying drawing, sound barrier is further described the utility model in conjunction with the embodiments:

See accompanying

drawing

1,2, the metallic plate of long 2m, wide 1m is processed with the zigzag relief structured surface of metal otter board (1), the back of tooth (7) spaced surface is provided with upper base 2mm, the trapezoidal faces of the 1.3mm that goes to the bottom, high 1.5mm (4), is provided with the prismatic (5) that indent has angle, transition garden between two trapezoidal faces (4); Prismatic (5) bottom line and metallic plate break away from, formation has angle, transition garden, highly be the triangle through hole (6) of 0.6mm, triangle through hole (6) forms the prismatic passage (8) with angle, transition garden with prismatic (5) inner concave space, and the angle a between the back of tooth (7) and crown (9) is 50 °.

See accompanying

drawing

1,2,3, the metallic plate of long 2m, wide 1M is processed with the zigzag relief structured surface of metal otter board (1), the back of tooth (7) spaced surface is provided with upper base 2mm, the trapezoidal faces of the 1.3mm that goes to the bottom, high 1.5mm (4), is provided with the prismatic (5) that indent has angle, transition garden between two trapezoidal faces (4); Prismatic (5) bottom line and metallic plate break away from, formation has angle, transition garden, it highly is the triangle through hole (6) of 0.6mm, triangle through hole (6) forms the prismatic passage (8) with angle, transition garden with prismatic (5) inner concave space, and the angle a between the back of tooth (7) and crown (9) is a kind of metal otter board (1) of 50 °.

Then, according to designing requirement, the supporting frame (3) and being fixed in that making can be held a kind of metal otter board (1) of long 2m, wide 1m is subjected on the face, by keel (2) metal otter board (1) is fixedlyed connected with supporting frame (3) and to be integral, form gobo, make sound wave collision and interference mutually on the zigzag relief structured surface, the sound wave that also has passes prismatic passage (8) and triangle through hole (6) enters in the gobo, formation penetrates and reflection loss, reach the reduction noise, reach the purpose of environmental protection.

A kind of metal otter board of the present utility model can also be used to prevent dust, filter and decorate.

Claims

1. metal otter board, it is characterized in that: the surface that is interval with the zigzag concaveconvex structure on the metallic plate, the back of tooth (7) spaced surface is provided with trapezoidal faces (4), be provided with the prismatic (5) that indent has angle, transition garden between two trapezoidal faces (4), prismatic (5) bottom line and metallic plate break away from, formation has the triangle through hole (6) at angle, transition garden, and triangle through hole (6) forms the prismatic passage (8) with angle, transition garden with prismatic (5) inner concave space.
