Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is used for a partition wall of a room that handles radioactive substances, such as an X-ray room or a radiotherapy room of a hospital, to prevent leakage of radiation to the outside. It's about panels.

[Prior Art] In a room that handles radioactive substances, such as an X-ray room or a radiotherapy room in a hospital, a lead plate is stretched over the partition wall to prevent leakage of radiation to the outside. In the case where such a lead plate is stretched, conventionally, a method has been adopted in which a long lead plate wound in a roll shape is sequentially unwound from the end and pressed against a wall surface to be fixed. It requires a lot of manpower to work together, and because the lead plate has a large mass and is flexible, not only is it hard work to support it, but it is also easy to partially bend and sag. The installation work was very troublesome.

In addition, after the lead plate is stretched, the decorative plate is stretched from above, but since the lead plate and the decorative plate must be stretched twice, it is extremely difficult to stretch them. It took a lot of work and time.

[Problems to be Solved by the Invention] An object of the present invention is to integrate a lead plate and a decorative plate into a single wall panel so that they can be stretched simultaneously and easily. It is in.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention forms a flange protruding outward on two adjacent side edges and adjoins the other two adjacent side edges to the above wall panel. A lead plate is stretched on a square plate-shaped decorative plate that is a contact side that overlaps on the flange,
It is characterized in that cutouts are formed in the corners of the decorative plate to prevent the flanges of adjacent wall panels from overlapping with each other by cutting off a part of the flanges.

Embodiments Embodiments of the present invention will be described in detail below with reference to the drawings.

As shown in FIGS. 1 to 3, the wall surface panel 1 of the present invention includes a decorative plate 2 having a rectangular dish shape and a lead plate 3 stretched integrally on the back surface of the decorative plate 2. ing.

The decorative plate 2 is formed of a metal plate such as iron, aluminum, or stainless steel. The metal plate has two adjacent side edges 2a and 2b inclined outward and the other adjacent two side edges. Bending in a rectangular dish shape in which 2c and 2d incline toward the inside, forming the flange 4 projecting outward on the above-mentioned two side edges 2c and 2d that incline toward the inside, and inclining toward the outside Two side edges 2a, 2b of the adjacent wall panel 1 to the side edges 2c, 2d having the above-mentioned flange 4 and the flange 4
It is a contact side that abuts in a state of being overlapped upward. By cutting off a part of the flange 4 at the corner portion of the decorative plate 2, overlapping of the flanges in the adjacent wall panel 1 is prevented. A notch 5 is formed for prevention. Further, the flange 4 is formed with a mounting hole 6 for fixing the wall material to the wall surface with a screw.

The decorative plate 2 may be subjected to surface treatment such as plating, painting, vinyl coating in advance.

Further, the lead plate 3 is stretched so as to cover the entire surface of the decorative plate 2 in a plane including the cutout portion 5. Therefore, the lead plate 3 is exposed on the surface in the cutout portion 5. ing.

As shown in FIGS. 4 to 6, the wall panel 1 having the above configuration is pressed against the wall surface 7 one by one in the same direction, and is stretched in order while being fixed to the wall surface 7 with the screw 8 at the position of the flange 5. I will do it. At this time, the outwardly sloping side edges 2a, 2b of the wall surface panel 1 are brought into contact with the inwardly sloping side edges 2c, 2d of the adjacent wall surface panel 1 in a state of being superimposed on the flange 4. As a result, the lead plate 3 in each wall panel 1 is stretched in a state where its ends are slightly overlapped, so that radiation does not leak to the outside from the joint between the wall panels 1 and 1. Further, since the screw 8 attached to the flange 4 is covered by the adjacent wall panel 1, the appearance of the screw 8 does not deteriorate due to the exposure of the screw 8.

In addition, the height of the side 2a, 2b which is overlapped on the flange 4 is
Both wall panels 1, in the state that they are superposed on the flange 4.
It is desirable to form the 1s so that they have the same height.

Further, in the portion where the corners of the four wall panels 1 abut, when the notch 5 is not formed in the flange 4, the flanges 4 of the three wall panels 1 and the lead plates 3 alternate. And each of them is superposed three-fold, and on top of that, the part sandwiched by the side edges 2a and 2b of the other one wall panel 1 which is inclined outward is covered, but in reality, it is superposed. Since the notch 5 is formed in the flange 4,
The flanges 4 do not overlap with each other, only the flexible lead plate 3 overlaps in triplicate. Therefore, there is no difficulty in mounting the wall surface panel 1 due to the overlapping of the hard flanges 4, and the mounting becomes very easy.

Although the side edges 2a to 2d of the decorative plate 2 are inclined in the above embodiment, they may be formed at right angles without being inclined.

[Effects of the Invention] As described above, according to the present invention, since the lead plate and the decorative plate are integrated to form one wall panel, the lead plate and the decorative plate are simply fixed to the wall surface in order. And can be stretched simultaneously and easily.

Further, since each wall panel is provided with a flange so that the adjacent wall panels can be fixed in an overlapped state by the flange, the lead plate is automatically stretched so that the end portions overlap each other by fixing the wall panel. Therefore, it is possible to reliably prevent the radiation from leaking from the joint of the wall panel.

Since the cutouts are formed in the corners of the decorative plate to prevent the flanges of the adjacent wall panels from overlapping, it is possible to prevent multiple flanges from overlapping at the abutting portions of the wall panels. , Wall panel can be easily installed.
