Description

A square tube sandwich rock wool board

technical field

The utility model relates to the technical field of rock wool board structures used in clean rooms, in particular to a square tube-core rock wool board.

Background technique

Cotton board, also known as rock wool thermal insulation decorative board, is an inorganic fiber board made of basalt as the main raw material and processed by high temperature melting. It is a good thermal insulation, flame insulation and sound absorption material. However, the effect of simply using rock wool board is not ideal; therefore, some companies improve its performance by adding some thermal insulation and sound insulation materials.

But usually for different situations, the performance of a single aspect is improved, while the performance of other aspects is flawed. In particular, our company is mainly aimed at medical clean rooms, and it is very important to prevent the survival of bacteria, so we specially designed a square tube sandwich rock wool board, which is tightly sealed to prevent bacteria from infiltrating, and also has fire prevention, heat preservation, and noise reduction. The function of each performance has been comprehensively improved.

Utility model content

The purpose of the utility model is to overcome the shortcomings of the prior art, and to provide a square tube sandwich rock wool board that is tightly sealed, prevents bacteria from immersing, is not easy to collapse, and has excellent fireproof, sound-absorbing and heat-preserving properties.

The purpose of the utility model is achieved through the following technical solutions: a square tube sandwich rock wool board, including rock wool outer layer board, rock wool inner layer board and elastic wave steel plate;

A filling layer of insulating material is arranged between the two rock wool inner layer boards, and the two rock wool inner layer boards are respectively provided with a rock wool outer layer board, and a rock wool outer layer board is arranged between the rock wool inner layer board and the rock wool inner layer board. Elastic corrugated steel plate;

A long cavity is formed between the elastic wave steel plate, the inner rock wool board and the outer rock wool board, and a long sound absorbing body with a wedge is arranged in the cavity;

The edges of the rock wool outer layer board, the rock wool inner layer board and the elastic corrugated steel plate are all covered by a square tube to form an integrated board;

The inner wall of the square tube is provided with an elastic support structure that makes the whole integrated plate tightly sealed.

Further, the size of the rock wool inner layer board is equivalent to that of the insulating material filling layer, and the length and width of the rock wool outer layer board are larger than those of the rock wool inner layer board.

Further, the elastic support structure includes a plurality of springs and installation cylinders, and the installation cylinders are correspondingly fixed by glue at the edges of the opposite surfaces of the two rock wool outer layer boards;

The same spring is arranged in the two corresponding installation cylinders.

Further, a certain gap is formed between the edges of the two rock wool outer layers and the elastic support structure, and the gap is filled with vitrified microbeads.

Further, a gap is formed between the long sound absorbing body and the elastic corrugated steel plate, which is convenient for the long sound absorbing body to vibrate.

Preferably, filling foam is arranged between the rock wool inner layer plate and the rock wool outer layer plate at the circumferential edge of the elastic wave steel plate.

Further, the square tube is a half-side tube cut by a rectangular tube, and the gaps formed between adjacent square tubes are filled with resin.

(1) By setting up an elastic support structure, the square tube and the rock wool outer layer are tightly sealed to prevent bacteria from immersing;

(2) The insulation effect of the whole board is improved by setting the insulation material filling layer, the sound absorption effect of the whole board is improved by setting the long sound-absorbing body, and the whole board is prevented from collapsing by setting the elastic corrugated steel plate, and the elastic wave board and the long sound-absorbing body are connected. There is a gap between them, so the heat transfer is slow and the fireproof effect is improved; therefore, the overall board in this scheme has both beneficial effects of sound absorption, heat preservation and fire prevention.

Detailed ways

The present utility model will be further described below in conjunction with the accompanying drawings, but the protection scope of the present utility model is not limited to the following.

As shown in FIGS. 1 to 3 , a square tube sandwich rock wool board includes a rock wool outer layer board 1 , a rock wool inner layer board 2 and an elastic wave steel plate 3 .

As shown in Figure 2, in this solution, a thermal insulation material filling layer 4 is arranged between the two rock wool inner layer boards 2, and the two rock wool inner layer boards 2 are respectively provided with a rock wool outer layer board 1. An elastic wave steel plate 3 is arranged between the layer board 1 and the rock wool inner layer plate 2; a long cavity is formed between the elastic wave steel plate 3 and the rock wool inner layer plate 2 and the rock wool outer layer plate 1. A long sound-absorbing body 5 with a wedge is arranged in the cavity; the edges of the rock wool outer layer board 1 , the rock wool inner layer board 2 and the elastic wave steel plate 3 are all covered by the square tube 6 to form an integrated board.

In order to improve the sealing effect and prevent bacteria from infiltrating, in this solution, the inner wall of the square tube 6 is provided with an elastic support structure 7 that makes the entire integrated plate tightly sealed. Specifically, the size of the rock wool inner layer board 2 and the insulation material filling layer 4 are equivalent, and the length and width of the rock wool outer layer board 1 are larger than those of the rock wool inner layer board 2; An elastic support structure 7 is provided.
