Problems solved by technology

[0004] However, although the above-mentioned utility model patents have improved various performances through the aluminum honeycomb core sandwich panel, there are also some shortcomings. For example, the aluminum honeycomb core sandwich panel is full of through holes, resulting in a small composite area with the flame retardant panel. , the flame retardant board and the aluminum honeycomb core sandwich board are easy to fall off, and the rework rate is high during processing; because the through holes are arranged according to the honeycomb rule, their plasticity is very poor, and it is difficult to process the curved board shape; the elastic recovery force is not enough, When the anti-acoustic cover panel is strongly impacted by heavy objects, it is easy to collapse and deform, and it is difficult to recover

Abstract

The invention provides a foamed aluminum sound reflecting cover which comprises a sound reflecting cover plate and a light filling core body. The sound reflecting cover plate comprises a front cover plate, a rear cover plate, a left cover plate and a right cover plate which are made of metal materials, and a filling cavity defined by the front cover plate, the rear cover plate, the left cover plate and the right cover plate, and the width of the filling cavity is 5 mm to 20 mm; the light filling core body is arranged in the filling cavity; and the sound reflecting cover plate and a foamed aluminum plate are both of an arch-shaped structure. The foamed aluminum sound reflecting cover has the beneficial effect that the foamed aluminum plate is ingeniously used for replacing an aluminum honeycomb core sandwich plate, various performance indexes of the sound reflecting cover are improved, and the sound reflecting cover is high in strength, light in weight and convenient to assemble, disassemble or carry; the damping shock absorbing performance and the impact energy absorption rate are high, and the anti-collision effect is good; reversibility is good, bending can be achieved through mold pressing, machining is easy, and the manufacturing process is simple; and the foamed aluminum sound reflecting cover is flexible in installation, rapid in construction, healthy, environment-friendly, reusable, pollution-free, mothproof, good in fireproof effect, firm, durable and free of deformation such as warping.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to an anti-acoustic enclosure for preventing noise pollution. Background technique [0002] In large-scale music performance stages such as conference rooms, concert halls or opera houses, anti-acoustic enclosures are widely used to improve viewing effects and sound transmission efficiency. The anti-acoustic enclosure is usually composed of multiple panel units that are resistant to moisture and flame-retardant, covering the entire stage to form a good anti-acoustic effect. The core part of the anti-acoustic enclosure is the anti-acoustic enclosure panel fixed on the anti-acoustic enclosure structure. Existing anti-acoustic cover panels are usually made of aluminum structure or wood structure panel materials, which are prone to metal vibrato and other situations during use, which will have a certain impact on the performance effect. However, due to structural reasons, various...
