[Structure] The summing part of the radiation shielding sliding door having lead sheets 4 attached on both sides has a stepped shape, and the mating part on the other side has a symmetrical shape with the summing part of the sliding door. To prevent the radiation from leaking from the sliding door assembly portion by shifting the abutting positions of the sliding door assembly portion distal end and the mating side assembly portion distal end.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a radiation shielding sliding door provided at an entrance / exit of an X-ray room or the like of a hospital, and more particularly to a fitting portion of the sliding door.

[0002]

[Prior Art]

 Lead sheets are embedded in walls and doors to prevent radiation from leaking outside, such as the X-ray room of a hospital. In such a radiation shielding sliding door, the summing portion also has a radiation shielding structure so that radiation does not leak from the summing portion.

A conventional radiation shielding sliding door will be described with reference to FIG.

FIG. 3 shows a draw sliding door. The door bodies 1 and 2 are constructed by laminating a lead sheet 4 on both surfaces of a core material 3 and attaching a surface panel 5 to the decorative panel 6. ..

A sealing material 7 made of a synthetic resin such as vinyl chloride is provided at the end of the door 1 on the assembly side. A lead sheet 9 extending to the one door 1 side via a spacer 8 is provided on both end surfaces of the other door body 2, and a cover panel 10 is provided to cover the lead sheet 9. ..

In the radiation shielding sliding door, when the door bodies 1 and 2 are closed, the end portion of the other door body 2 is inserted into the recess formed by the one door body 2 and the lead sheet. In this state, the door body is shielded by the lead sheet 4, and the assembled portions of the door bodies 1, 2 are shielded by the lead sheet 9.

[0007]

[Problems to be solved by the device]

 In the conventional radiation shielding sliding door described above, the number of parts such as the spacer 8, the lead sheet 9 and the cover panel 10 is increased as the structure of the assembling portion, and mounting of these is troublesome and there is a problem in workability and manufacturing cost. It was Further, since the spacer 8, the lead sheet 9, the cover panel 10 and the like have a shape protruding in the thickness direction of the door body, there is a problem in designability and the sliding dimension of the sliding door is large.

[0008]

[Means for Solving the Problems]

 In the present invention, the summing part of the radiation shielding sliding door having lead sheets adhered on both sides has a stepped shape, and the mating side mating part has a symmetrical shape with the sliding door summing part, and the summing part is in a closed state. Is characterized in that it is polymerized.

[0009]

[Action]

 Since the sliding door summing part has a stepped shape, the contact position between the sliding door summing part tip and the mating side mating part tip is displaced, and leakage of radiation from the sliding door summing part is prevented.

[0010]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, the same parts as those shown in FIG. 3 are designated by the same reference numerals. Since the assembled portions of the door bodies 11 and 12 are point-symmetrical, the door body 12 will be described below.

The frame body 13 provided at the end of the door body 12 forms a concave groove 14, and one of the two groove walls 16 a and 16 b forming the concave groove 14 is higher than the other. The lead sheets 4, the front panel 5, and the decorative panel 6 on both sides are attached so as to match the edges of the groove wall of the groove 14. The assembly seal member 15 is fitted on the frame body 13.

The assembling seal member 15 is composed of a base material 22 and a seal material 21 integrally attached to the base material 22, and the base material 22 is in contact with an end edge of the groove wall 16b. 16 a, a lid portion 17 that abuts on the wall surface, a hook-shaped fitting protrusion 18 b formed on the inner surface of the end portion of the lid portion 17 on the groove wall 16 b side, the outer surface of the lid portion 17, and the thickness of the door body 12 A standing piece 19 protruding toward the other door at a substantially central position, a seal material holding portion 20 formed at the tip of the standing piece 19, and a hook-like shape formed on the back surface of the sealing material holding portion 20. It is integrally formed from the fitting ridge 18a. The fitting protrusions 18a and 18b are adapted to fit in the concave grooves 14, and the bent portions of the decorative panel 6 are inserted in the grooves formed by the fitting protrusions 18a and 18b. Prevents the assembly seal member 15 from coming off.

Thus, the assembling portion of each door body has a stepped shape, and in the closed state as shown in FIG. 1, the standing pieces 19 are overlapped with each other, and the sealing material 21 is the lid portion 17 of the other door body. Abut. Further, the lead sheet 9 is cut off on one side surface of the door body by the amount of the sealing material 21, but the position of the sealing material 21 is displaced on the other side surface. There will be no breaks. Further, as described above, the summing portion of each door body 11 and 12 has a stepped shape, and the standing pieces 19 overlap each other in the closed state, so that the effect of shielding light, wind, etc. is great.

The shape of the assembling seal member 15 can be variously modified and is not limited to the above-mentioned shape.

It goes without saying that the present invention can also be applied to a single-sliding door.

[0017]

[Effect of the device]

 As described above, according to the present invention, since the shape of the assembling portion of the drawing sliding door is the same, it is only necessary to prepare the same parts for the left and right sliding doors. Since the steps are the same and the number of processing steps is reduced, the manufacturing cost is reduced, and since it is not necessary to provide a separate part for the door body, the design is improved and the installation size is reduced.
