Abstract
The present invention discloses a metal otter board. Sawtooth concave-convex structure surfaces are arranged on a metal board at intervals of 1.5-3mm, trapezoidal surfaces with the upper bottom of 1.5-3mm, the lower bottom of 1.0-1.8mm and the height of 1.2-2mm are arranged on the tooth back surface at intervals, a prism which is inward sunken and is provided with a transition fillet is arranged between two trapezoidal surfaces, the bottom line of the prism is detached from the metal board and is provided with a triangular through hole with a transition fillet, and the triangular through hole detached from the metal board forms a prism channel provided with a transition fillet with a prism inner sunken surface space, therefore, the invention solves the defects that the sound absorption effect of a combination type sound absorbing board is influenced if sound absorption material is moistened and sound waves can not be decayed; in addition, the present invention greatly simplifies the production of sound absorbing screens, enhance the working efficiency, saves material of the sound absorbing screens by 80 percent, lowers the construction cost by above 50 percent and achieves the purposes of lowering noises and protecting the environment.
Description
One, technical field:
A kind of metal otter board of the present invention, 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 the combination of materials formula acoustic board of porose sheet metal and energy noise reduction, or adopts the acoustic absorbant of band fibre properties such as essence.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 acoustic absorbant and has used.
Three, summary of the invention:
The objective of the invention is to overcome above-mentioned defective, by to the punching press of sheet metal or roll worker's technology, design and a kind ofly can solve requirements such as acoustical material makes moist, fire prevention, do not influence a kind of metal otter board of sound-absorbing effect again.It is characterized in that: the serrate relief structured surface that is interval with 1.5～3mm spacing on the sheet metal, back of tooth spaced surface is provided with upper base 1.5～3mm, 1.0～1.8mm goes to the bottom, the trapezoidal faces of high 1.2～2mm, be provided with the prismatic that indent has knuckle between two trapezoidal faces, prismatic bottom line and sheet metal break away from, formation has the triangle through hole of knuckle, triangle through hole and prismatic inner concave space form the prismatic passage with knuckle, height with triangle through hole of knuckle is 0.4～0.8mm, and the angle a between the back of tooth and crown is 48～52 °.The positive effect of implementing after this technology is: both solved acoustic absorbant 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 work 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 synoptic diagram of the present invention;
Fig. 2 looks the sectional structure synoptic diagram for a left side of the present invention;
Fig. 3 is the structural representation of embodiments of the invention sound barrier;
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, embodiment:
Following with reference to accompanying drawing, sound barrier is further described the present invention in conjunction with the embodiments:
See accompanying drawing 1,2, the sheet metal 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 knuckle between two trapezoidal faces (4); Prismatic (5) bottom line and sheet metal break away from, formation has knuckle, highly be the triangle through hole (6) of 0.6mm, triangle through hole (6) forms the prismatic passage (8) with knuckle 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 sheet metal 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 knuckle between two trapezoidal faces (4); Prismatic (5) bottom line and sheet metal break away from, formation has knuckle, it highly is the triangle through hole (6) of 0.6mm, triangle through hole (6) forms the prismatic passage (8) with knuckle 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 serrate relief structured surface, the sound wave that also has passes prismatic passage (8) and triangle through hole (5) 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 invention can also be used to prevent dust, filter and decorate.
Claims (3)
1. metal otter board, it is characterized in that: the serrate relief structured surface that is interval with 1.5～3mm spacing on the sheet metal, the back of tooth (7) spaced surface is provided with upper base 1.5～3mm, the trapezoidal faces of the 1.0～1.8mm that goes to the bottom, high 1.2～2mm (4), be provided with the prismatic (5) that indent has knuckle between two trapezoidal faces (4), prismatic (5) bottom line and sheet metal break away from, formation has the triangle through hole (6) of knuckle, and triangle through hole (6) forms the prismatic passage (8) with knuckle with prismatic (5) inner concave space.
