Description

Technical Field

[0001] The utility model relates to the technical field of building plates, in particular to a clean plate for a clean room top plate. Background Art

[0002] At present, the clean room of large-scale food clean factories needs to install a top plate with high load-bearing requirements. The top plate is generally made of stainless steel double glass magnesium rock wool hand-made clean board. Specifically, the two outer sides of the rock wool board perpendicular to its own thickness are respectively bonded to the glass magnesium board through a glue layer, and the two outer sides of the glass magnesium board are respectively bonded to the stainless steel panel through a glue layer. That is, this setting method requires the use of glue to complete the bonding and compounding process of the five-layer board during the factory processing, and there are many production processes, which is not conducive to improving the factory's production efficiency. Utility Model Content

[0003] The utility model provides a clean plate for a clean room top plate, which can at least solve one of the above technical problems.

[0004] In order to solve the above technical problems, one or more embodiments of the utility model provide a clean panel for a clean room ceiling, comprising a composite core panel, stainless steel panels are respectively attached to the two sides of the composite core panel perpendicular to its own thickness direction, the stainless steel panels are 0.4mm to 0.6mm thick, and a glue layer is provided between the side of the composite core panel and the stainless steel panels; the composite core panel comprises a rock wool board, and the apparent density of the rock wool board is 90 to 110 kg / m 3 The two sides of the rock wool board perpendicular to its thickness are the bonding surfaces, and the bonding surfaces are respectively provided with cement fiber boards, and the apparent density of the cement fiber boards is 900-1100kg / m 3 , with a thickness of 4mm to 6mm. The cement fiber board and the rock wool board are pressed and formed as a whole. At least part of the cement fiber board penetrates into the rock wool board from the bonding surface to form a bonding layer.

[0005] Furthermore, the two side surfaces of the rock wool board perpendicular to its thickness direction are connecting surfaces, and a plurality of dovetail grooves are evenly distributed on the connecting surfaces. The dovetail grooves at the two connecting surfaces of the rock wool board are staggered along the direction perpendicular to the thickness of the rock wool board. The opening of the dovetail groove gradually increases in the direction close to the center of the rock wool board. Along the direction perpendicular to the thickness of the rock wool board, the projections of the dovetail grooves at the two connecting surfaces do not overlap, and the sum of the areas of the projections of the dovetail grooves at the two connecting surfaces is equal to the area of ​​the connecting surface. The beneficial effects of one or more of the above technical solutions are:

[0006] (1) Compared with the method in the prior art of bonding two layers of magnesium oxychloride boards and rock wool with adhesive to form a core material, this solution uses a composite core board formed by integrally pressing rock wool and cement fiber board. This composite core board can be prefabricated before the clean board is produced in the factory, thus saving the process of bonding the magnesium oxychloride board and rock wool with adhesive, which is beneficial to simplifying the process of the clean board itself and improving the production efficiency of the clean board. Additionally, this structural arrangement facilitates the infiltration of part of the cement slurry into the rock wool before the cement fiber board is completely solidified, and then the infiltrated part in the rock wool forms a bonding layer. The bonding layer can be used to fix the solidified cement fiber board and the rock wool, increasing the stability of their connection.

[0007] (2) In this solution, dovetail grooves are staggeredly arranged on two connecting surfaces of the rock wool board, and the opening of the dovetail groove gradually becomes larger along the direction close to the center of the rock wool board. This arrangement is convenient for using the dovetail groove to accommodate the slurry of the non-solidified cement fiber board, and can limit their separation along the thickness direction through the special structure of the dovetail groove after the cement fiber board is solidified.
