Description

Technical Field

[0001] The utility model belongs to the technical field of darkroom absorbing material installation, and in particular relates to a ceiling and wall absorbing material fixing structure for a large darkroom. Background Art

[0002] With the development of modern science and technology, the impact of electromagnetic radiation on the environment is increasing. Absorbing materials refer to a type of material that can absorb or significantly reduce the electromagnetic wave energy received on its surface, thereby reducing the interference of electromagnetic waves. In engineering applications, in addition to requiring absorbing materials to have a high absorption rate of electromagnetic waves in a wide frequency band, they are also required to have properties such as light weight, temperature resistance, moisture resistance, and corrosion resistance.

[0003] At present, when electromagnetic compatibility darkrooms are used for product testing, they will test products of different types and sizes, such as various large military equipment such as aircraft. These equipment require a relatively large test space, so the size of the darkroom needs to reach a height of more than 20m. At this height, the installation of absorbing materials inside the darkroom will be very inconvenient. At the same time, the existing technology is to achieve the flatness of the darkroom by reverse installation of steel plates, thereby providing a platform for gluing absorbing materials. Since glue is volatile, when the volatile substances in the air reach a certain concentration, it is easy to cause an explosion, causing life-threatening dangers; the aforementioned gluing method will volatilize a large amount of volatile substances, posing a great safety hazard.

[0004] Therefore, the present invention provides a ceiling and wall absorbing material fixing structure for a large darkroom to eliminate the potential safety hazards existing in the above-mentioned background technology. Utility Model Content

[0005] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a ceiling and wall absorbing material fixing structure for a large darkroom.

[0006] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0007] A ceiling and wall absorbing material fixing structure for a large darkroom comprises an absorbing material, a plurality of top keels, a top absorbing material back plate and a top plate, wherein the top keel is fixedly provided with a first bent edge, and two sides of the top absorbing material back plate are respectively provided with second bent edges, the first edge and the second edge are hung with each other, the absorbing material is fixedly connected to the top absorbing material back plate, and the top keel is fixedly connected to the top plate.

[0008] It is further defined that the top keel and the top plate are both made of steel.

[0009] It is further defined that the first folded edge is concave, and the second folded edge is inversely concave. Such a structural design enables the first folded edge and the second folded edge to be hung on each other, and this installation method is very stable and convenient.

[0010] It is further defined that the absorbing material and the top absorbing material back plate are bonded with glue.

[0011] It is further defined that the absorbing material includes a plurality of sawtooth-shaped protrusions. With such a structural design, the absorbing material is designed to be sawtooth-shaped, and the sawtooth shape of the surface can be used to realize multiple reflections and scattering of electromagnetic waves, and the energy of the electromagnetic waves is dissipated in the multiple reflections and scattering.

[0012] Beneficial effects of the utility model:

[0013] The existing technology realizes the flatness of the darkroom interior by reverse installation of steel plates, thereby providing a platform for gluing absorbing materials. Since the glue is volatile, when the volatile substances in the air reach a certain concentration, it is easy to cause an explosion, causing life-threatening dangers. Such gluing method will volatilize a large amount of volatile substances, which poses a great safety hazard. The present solution provides a ceiling wall absorbing material fixing structure for a large darkroom, which is provided with absorbing materials, top keels, top absorbing material backboards, top steel plates, first folding edges and second folding edges. During installation, the glue gluing link is placed outdoors, so that the substances volatilized by the glue can be quickly dispersed. After the glue is completely dry, the absorbing material and the backboard are hung on the top steel keel as a whole, which can eliminate the safety hazard caused by the volatilization of glue in a confined space.

[0023] Preferably, the top keel 2 and the top plate 4 are both made of steel.

[0024] Preferably, the first folded edge 5 is concave, and the second folded edge 6 is inversely concave. Such a structural design enables the first folded edge and the second folded edge to be hooked to each other, and this installation method is very stable and convenient.

[0025] Preferably, the absorbing material 1 and the top absorbing material back plate 3 are bonded with glue.

Since the top absorbing material back plate 3 is respectively provided with a bent second folded edge 6 on both sides, the top keel 2 is fixed with a bent first folded edge 5. After waiting for the glue to dry thoroughly (volatile substances are not easily generated), the absorbing material 1 and the top absorbing material back plate 3 are finally hung on the top keel 2 as a whole. In this solution, the glue gluing process is placed outdoors during installation, so that the substances volatilized by the glue can be quickly dispersed, which can eliminate the safety hazards caused by the volatilization of glue in a confined space.
