An aluminum honeycomb ceiling panel with a micro-perforated sandwich layer

Abstract

The invention relates to an aluminum honeycomb ceiling panel with a micro-perforated sandwich layer, comprising an upper aluminum plate, a lower aluminum plate, and a micro-perforated sandwich layer bonded between the upper aluminum plate and the lower aluminum plate; the micro-perforated sandwich layer is A number of breakable dotted line slots are uniformly opened, and each of the breakable dotted line slots is connected end to end to form a closed loop, and a sandwich block to be pushed out is formed in the closed loop to be connected to the micro-perforated sandwich layer through a plurality of ribs. The present invention uses the raised aluminum plate and the groove on the upper aluminum plate and the lower aluminum plate to correspond to the sandwich block to be pushed out on the micro-perforated sandwich layer, and the pressing operation can make the three nested with each other, and the sound-absorbing structure extends into the aluminum plate, increasing the The sound-absorbing area is increased, and the sound-absorbing efficiency is increased. The raised aluminum plate extends into the micro-perforated sandwich layer to support the micro-perforated sandwich layer to avoid deformation and peeling of the micro-perforated sandwich layer. The entire ceiling panel not only has high strength, but also absorbs sound The effect is also better.

Description

technical field [0001] The invention belongs to the technical field of interior decoration materials, and in particular relates to an aluminum honeycomb ceiling board with a micro-perforated sandwich layer. Background technique [0002] At present, aluminum plate ceilings have been widely used. Generally, folded edges are set on the back of the decorative surface of the aluminum plate, which is used to clamp the hooked aluminum plate on the top for sliding assembly. , and in order to meet functional requirements such as sound absorption and noise reduction, an interlayer with sound absorption or other functions is generally provided inside the aluminum plate. [0003] The interlayer in the existing aluminum plate is divided into two types: [0004] One is directly bonded and fixed between two aluminum plates, the edges are exposed to the air, the adhesive layer is easily peeled off by the environment, and in order to increase the stability of the connection, the general met...

Problems solved by technology

[0004] One is directly bonded and fixed between two aluminum plates, the edges are exposed to the air, the adhesive layer is easily peeled off by the environment, and in order to increase the stability of the connection, the general method is to glue the bonding surface between the aluminum plate and the interlayer It is designed as a special-shaped surface, but the special-shaped surface of the aluminum plate and the interlayer must be processed separately, especially the processing of the interlayer is more difficult, which leads to complex processes, high processing costs, and low efficiency;

[0005] The other is fixed in an empty box-type aluminum plate. Since the interlayer is set inside the aluminum plate, there will be a section without interlayer after splicing between the aluminum plates, which will lead to poor sound absorption and other effects.
