Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a mullioned door frame of a partition having a lead room configuration in an X-ray room or the like.

In a lead room structure to prevent the leakage of short-wavelength invisible light (such as Since it is done over a wide area, there are relatively few problems. However, in the case of a door mullion frame, the frame material often has an uneven shape.
Moreover, since the change occurs over a narrow and small width, it is extremely difficult to install a lead plate that completely captures the change and seals the gap exposed to X-rays.

If the frame of the mullion to be erected were to be wrapped in a decorative board as a lead column like an ingot, it would be very heavy, and the fixing method and installation work would be difficult, especially the upper girder frame. In order to support and maintain the weight and hardness, the overall shape of the mullion frame is also large. Generally, a lead plate having a thickness of 2 to 3 mm or 4 mm is considered to be sufficient for sealing.

In addition, it is not desirable for environmental hygiene and aesthetics to leave the lead plate facing indoors or outdoors, so lead plates are pasted on the back side of the front panels of room partition panels, etc. There has been a demand for an exterior that is no different from the interior. However, it is very difficult to fold a lead plate with a thickness of 2 to 4 mm into the uneven inside of the mullion frame in accordance with changes in the shape of the inside of the frame. In particular, the shape of the right-angled corners (rounded) is difficult to obtain. For this reason, lead plywood is used, in which 2 mm of lead is spread on the surface of plywood approximately 6 mm thick.
However, even with lead plywood, for example, the side edges of the lead plywood are always in contact with the inside of the frame.
The lead seal on this side edge has not been made. Furthermore, lead plywood is heavy and difficult to handle, and is also expensive.

By dividing the conventional mullion frame (hereinafter referred to as door frame, etc.) and reinforcing frame material into a plurality of parts, the present invention provides a general partition room with good work efficiency and manufacturing efficiency, complete sealing effect, and This resulted in a door frame that was no different from the original.

To explain an embodiment of the present invention with reference to the drawings, a metal door frame 1 forms left and right columns of a mullion.
Frame 2, 2 and upper frame 3 that constitutes the raised part of the mullion
It becomes more.

The upper frame 3 has a decorative frame 4 for room A and a door frame 5 for the A door as outer frames, and in the conventional case, it is formed in one piece, but in the present invention, this is made into an assembly of two frames. It is composed of a combination of That is, the upper frame 3 with a general cross-section of 〓〓〓 is vertically divided at the door stop part 6, and a decorative frame 4 for room A with a general cross-section of 〓〓 and a door frame 5 for A door with a rough cross-section of 〓 have. And the upper frame 3 is a decorative frame 4 for room A and a door frame 5
It has auxiliary frame members made of metal or the like, which are fitted into the outer frame that serves as a sealing effect and reinforcement, that is, an ax auxiliary frame 7, an ay auxiliary frame 8, and an ay auxiliary frame 9.

As shown in Fig. 1, the ay supplementary frame 7 has a substantially same U-shape that is fitted inside the decorative frame 4 for room A, has a long lower side, and has a width piece protruding outward at right angles from the tip of the lower side. It has a door stop cover 10, and a small wall portion 21 is a width piece projecting inward at right angles from the tip of the upper side. The ay supplementary frame 8 has a square cross section and is a frame body that is tightly fitted between the A-room decorative frame 4 and the A-door frame 5. Furthermore, the az supplementary frame 9 has a roughly U-shaped cross section and is fitted into the door stop frame 5, with a width piece protruding inward at right angles from the lower end of the U-shape, so that the door stop portion 6
have.

On the other hand, the upright frame 2 also has the same configuration as the upper frame 3. Therefore, for the sake of distinction, the symbols A and a given to the structure of the upper frame 3 will be replaced with B and b for the vertical frame 2 in the explanation.

The vertical frame 2 has a decorative frame 12 for the B room and a frame 13 for the B door as its outer frames, and in the conventional case, they are formed in one piece, but in the present invention, these are formed into two frames. It is composed of a combination of
That is, the upright frame 2, which has a general cross-section of 〓〓〓, is vertically divided at the door stop part 6, and a decorative frame 12 for room B, which has a general cross-section of 〓〓, and a B door frame 13, which has a rough cross-section of 〓〓, are created. It consists of The upright frame 2 is a reinforcing frame material made of metal or the like, which is fitted into the outer frame constituted by the decorative frame 12 for B room and the B door frame 13, and serves as a sealing effect and reinforcement, that is, a BX supplementary frame. 14,
It has a by complementary frame 15 and a bz complementary frame 16.

As shown in Fig. 2, the bx supplementary frame 14 is a U-shaped one that is fitted inside the decorative frame 12 for room B, and has a long lower side and a width piece that protrudes outward from the tip at a right angle. It has an abutment cover 10 (not fitted inside), and a small wall portion 21 of a width piece projecting inward at right angles from the tip of the upper side opposite to the lower side.

The BY complementary frame 15 is a frame body that is fitted tightly between the B room decorative frame 12 and the B door frame 13, similar to the aforementioned AAY complementary frame 8. The complementary frame 16 has a generally U-shaped cross section and is fitted into the door stopper frame 13, and has a door stop portion 6 (not fitted inside) with a width piece protruding inward at right angles from the tip of the lower side of the U-shape.

The vertical frames 2, 2 and the upper frame 3 are connected by known joints,
For example, the door frame 1 is constructed by connecting them to each other using a 45-degree split joint method.

Now, in order to install the lead plate 17 inside the door frame 1, immediately attach the lead plate 17 to the inner wall of the ax supplementary frame 7 in the upper frame 3 with lead plate tape, and then
It is fitted inside the decorative frame 4 for the room. A lead plate 17 is exposed to the outside of the door stop cover 10. Next, the corner angle 19 on the indoor side of the ay supplementary frame 8 in the fitted state,
That is, lead plates 17 are pasted to the required width on both sides of the corner angle 19 on the side facing the small wall portion 21 of the ax supplementary frame 7, and this ay supplementary frame 8 is inserted into the ay supplementary frame 7 described above. fit.

As described above, the sealing setting of the indoor lead plate 17 on the upper frame 2 is completed except for the door stop 6 portion. Next, a lead plate 17 is pasted on the door stop part 6 of the az supplementary frame 9, and it is fitted into the A door frame 5, and the end of the lead plate 17 of the door stop part 6 is pressed down with a puncher, and the aforementioned ayh supplementary frame 8, Decorative frame 4 for room A loaded with ax supplementary frame 7
Push them together. Then, the other end of the ay supplementary frame 8 is fitted into the door stop frame 5, and the door stop cover 10 of the ax supplementary frame 7 and the door stop part 6 of the az supplementary frame 9 are attached to the surface to which the lead plate 17 is attached. are in contact with each other and overlap. Therefore, the sealing of the lead plate 17 of the doorstop part 6 is also completed.

The decorative frame 4A for room A and the door frame 5 are joined by known means. The internal setting of the lead plate 17 in the upright frame 2 is also completely unchanged from that in the upper frame 3 described above. Therefore, the only difference is the code for differentiation. First, attach the lead plate 17 to the inner wall of the bx supplementary frame 14.
A lead plate 17 is quickly attached with tape, and this is fitted into the decorative frame 12 for room B. At the doorstop cover 10, the lead plate 17 is exposed to the outside. Next, at the corner 19 on the indoor side of the BX supplementary frame 15 in the fitted state, that is, at the corner 19 on the side facing the small wall 21 of the BX supplementary frame 14, a lead plate 17 is placed on both sides to a required width. This by supplementary frame 15 is then inserted into the aforementioned bx supplementary frame 14 with the part where the lead plate 17 is attached first. The other end of the complementary frame 15 is not fitted inside and is in a protruding state.

Next, a lead plate 17 is pasted on the door stop part 6 of the BZ auxiliary frame 16, and the lead plate 17 is fitted into the B door contact frame 13, and the door stop part 6 which is not in contact with the B door contact frame 13 is inspected using a door checker. Press the edges of the B door stopper frame 13 and the B room decorative frame 12, and join the doorstop cover 10 and the doorstop part 6 by overlapping each other,
Complete the above frame 2. The upright frames 2, 2 and the upper frame 3 are joined to form the door frame 1 of the present invention.

In Figures 1 and 2, the lead plates 17 are not attached to the small walls 21, 21 of the ax and bx supplementary frames 7, 14, but it is difficult to attach the lead plates in the corners where the recesses are small. This is to show that the lead plate 17 may of course be attached to this part as well. However, since the work of pasting the lead plate 17 on the convex member is easy, it is not necessary to paste the lead plate 17 on that part.
The seal is completely complemented by a 17-width piece of lead plate affixed to both sides.

The sealing situation of the lead plate 17 toward the room can be seen in Figures 3 and 4. Seals other than the door frame 1 can be completely provided on the door body 18 and the panel 20 by a lead plate 17 extending straight over a wide width. The door (shoulder body 18) is usually provided with a lead plate on the outside surface side, and this means that it is in contact with the door stop cover 10 of the door frame 1 and the lead plate 17 of the door stop part 6. It's for a reason. In the figure, reference numeral 22 is a rubber cushioning material. According to the present invention, there is no need to affix the lead plate 17 to the entire interior of the door frame 1, and in this case, there is no need for the present invention to increase the size of the frame relative to the weight of lead. The work of pasting the lead plate 17 is easy because the concave parts of the supplementary frames 7 and 14 of ax and bx have wide open surfaces, and the lead plate 17 tape can be neatly attached to the corners. There is no difficulty in doing so.
Also, even if there is a slight 〓 interval, ay and by complementary frames 8,
Since the shank corners 19, 19 of 15 are convex parts, the space between them is sealed by the lead plate 17 attached thereto. ax,
All of the lead plates 17 except for the bx supplementary frames 7 and 14 are in convex portions and are small parts, and the above work can be carried out extremely easily and with less weight burden on the lead plates 17. The work of forming the vertical frames 2, 2 and the upper frame 3 is also extremely easy. For example, top frame 3
, the ax supplementary frame 7 is fitted into the decorative frame 4 for room A, the ay supplementary frame 8 is fitted inside the crosspiece 23 and combined, and the A door per frame 5 with the az supplementary frame 9 fitted inside. The shape of the frame body,
The appearance is no different from ordinary partition materials. Even when increasing or decreasing the thickness of the lead plate 17, the supplementary frame,
In particular, by giving the ay and by complementary frames 8 and 15 an adjustable width, they will not cause any trouble. As described above, the present invention is a significant creation with the above-mentioned remarkable effects.
