Abstract
The utility model relates to a sound absorption screen discloses a there is not compound sound absorption screen of riveting, including frame (2) and acoustic baffle (1), frame (2) are equipped with triangle recess (25) of placing spring card (5) including diaphragm (21), fossil fragments (22), backplate (23) and curb plate (24) on diaphragm (21), and polyester fiber board (3) card is established between triangle recess (25) and acoustic baffle (1). The utility model discloses the all -screen body adopts mechanical butt -joint and the clamping groove group form of closing, has that the outward appearance is bright and clean, a sound construction, long service life, but and advantage such as pollution -free recycling.
Description
Technical field
This utility model relates to gobo, has particularly related to a kind of without riveting composite sound absorbing screen.
Background technology
At present, traditional gobo uses the connected modes such as riveting, welding, though riveting, welding gobo
So processing is simple and convenient, but outward appearance is coarse, sound construction is the highest and service life is short, and soundproof effect is poor.
Summary of the invention
This utility model rivets for employing in prior art, the welding many outward appearances of gobo are coarse, sound construction
The shortcomings such as the highest, service life is short, soundproof effect difference, it is provided that a kind of full frame body uses machinery butt-joint and card
Groove combining form, has smooth appearance, sound construction, ring long and pollution-free, callable in service life
Guarantor's type is without riveting composite sound absorbing screen.
In order to solve above-mentioned technical problem, this utility model is addressed by following technical proposals:
Without riveting composite sound absorbing screen, including framework and acoustic board, framework include transverse slat, Os Draconis, backboard with
And side plate, transverse slat is provided with the triangle groove placing Spring Card, and polyester fiber board is fastened on triangle groove and suction
Between sound plate.Fill out polyester fiber board inside acoustic board and both can play deadening, can reach again fire-retardant anti-
The purpose of fire, this utility model uses metal dust electrostatic spraying without riveting composite sound absorbing screen, outer surface, is coated with
Layer >=60 μm.Use metal dust electrostatic spraying, make this utility model have anticorrosion and outer surface and surrounding ring
Border matches.
As preferably, acoustic board is compound pin hole aluminum acoustic board.Compound pin hole aluminum acoustic board adds and uses nothing man-hour
Gap punching, non-secondary pollution and can the advantage such as reuse, length in service life, weatherability be strong, waterproof, capable of washing.
As preferably, it is cavity between backboard and polyester fiber board.
As preferably, Spring Card is triangle fixed strip Spring Card.Triangle fixed strip Spring Card is wanted quickly to fix
Acoustic board and the connection shielding body grillage, the advantage with easy accessibility.
As preferably, base of frame arranges apopore.By arranging apopore in base of frame, prevent from raining
It time gobo in produce hydrops.
As preferably, backboard arranges ethylene-propylene-diene monomer adhesive tape.Strengthen screen body to seal with H profile steel column, carry
High defening effect.
This utility model, owing to have employed above technical scheme, has a significant technique effect: this utility model
Full frame body uses machinery butt-joint and draw-in groove combining form, has smooth appearance, sound construction, service life long,
And the advantage such as pollution-free, recyclable.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment 1.
Fig. 2 is A-A face sectional view in Fig. 1.
Fig. 3 is the enlarged drawing in I portion in Fig. 2.
Fig. 4 is the top view of Fig. 1.
Fig. 5 is ethylene-propylene-diene monomer adhesive tape structure chart.
The toponym that in the figures above, each number designation is referred to is as follows: wherein 1 acoustic board, 2 frameworks,

Transverse slat, 22 Os Draconis, 23 backboards, 24 side plates.
Detailed description of the invention
This utility model is described in further detail by 1 to Fig. 5 with embodiment below in conjunction with the accompanying drawings:
Embodiment 1
Without riveting composite sound absorbing screen, as shown in Figures 1 to 5, including framework 2 and acoustic board 1, framework 2
Including transverse slat 21, Os Draconis 22, backboard 23 and side plate 24, transverse slat 21 is provided with places the three of Spring Card 5
Angle groove 25, polyester fiber board 3 is fastened between triangle groove 25 and acoustic board 1.
Fill out polyester fiber board 3 inside acoustic board 1 and both can play deadening, fire-retardant fireproof can be reached again
Purpose, this utility model without riveting composite sound absorbing screen, outer surface use metal dust electrostatic spraying, coating
≥60μm.Acoustic board 1 is compound pin hole aluminum acoustic board.Compound pin hole aluminum acoustic board adds and uses man-hour zero-clearance to rush
Hole, non-secondary pollution and can the advantage such as reuse, length in service life, weatherability be strong, waterproof, capable of washing.The back of the body
It it is cavity 4 between plate 23 and polyester fiber board 3.Spring Card 5 is triangle fixed strip Spring Card.Triangle is fixed
Bar Spring Card wants the connection that can quickly fix acoustic board with screen body grillage, the advantage with easy accessibility.Framework 2
Bottom arranges apopore 6.By arranging apopore 6 bottom framework 2, produce in gobo when preventing rainy day
Raw hydrops.By arranging ethylene-propylene-diene monomer adhesive tape 7 on backboard 23, strengthen screen body and H profile steel column seal,
Improve defening effect.
In a word, the foregoing is only preferred embodiment of the present utility model, all apply for a patent according to this utility model
Equalization change and the modification that scope is made, all should belong to the covering scope of this utility model patent.
