Description

The present invention relates to an architectural structure equipped with a screening door.

In building structures with rooms under high radiation levels, such as nuclear power plants and factories, maintenance must be performed by remotely moving a lifting machine to another room to reduce worker exposure. In such cases, a shielding door is installed at the boundary between the room in the high-radiation area and the maintenance room. Conventional shielding door technology includes, for example, that described in Patent Document 1.

Patent Document 1 describes a screening door that can be opened and closed via hinges in a concrete opening. It also describes technology in which the door is made from a single thick, ash-colored iron plate, and the side of the door that opens is formed with multiple inclined surfaces at different angles, while the side of the opening that corresponds to the inclined surfaces is formed with an inclined surface that is parallel to the inclined surfaces.

In recent years, sliding shielding doors that slide horizontally have become more common.

Japanese Patent Application Publication No. 10-132996

However, in order to move a mobile object from the first room to the second room, the opening formed at the boundary between the first and second rooms must be large enough for the mobile object to pass through, and the size of the screening door must also correspond to the size of the opening. Therefore, when a sliding screening door is used, it is necessary to secure space above, below, or to the left and right of the opening when the screening door is open, i.e., a door pocket, resulting in wasted space in the building structure.

Furthermore, in order to move the mobile object from the first room to the second room, it is necessary to install rails along which the mobile object moves. With the technology described in Patent Document 1, the rails interfere with the screening door when it is opened, which means that the rails must be installed and removed each time the screening door is opened or closed, making the process of moving the mobile object extremely complicated.

In consideration of the above problems, the present invention aims to provide an architectural structure that can prevent the generation of wasted space and allows moving objects to move smoothly.

To solve the above problems and achieve the objectives, the screening door comprises a door body, a door-side rail, and a hinge. The door body opens and closes an opening that connects a first room and a second room in an architectural structure. The door-side rail is provided on one side of the door body that faces the first room when closed. One end of the hinge is attached to a frame provided at the bottom end of the opening, and the other end is attached to the door body.

The building structure also includes a first room in which a first building-side rail is installed, a second room adjacent to the first room in which a second building-side rail is installed, and a shielding door that can be opened and closed to cover the opening connecting the first room and the second room. The shielding door is the same as the one described above.

According to the architectural structure having the above configuration, it is possible to prevent the occurrence of wasted space and to allow moving objects to move smoothly.

The following describes examples of embodiments of architectural structures and shielding doors. Note that common components in each figure are designated by the same reference numerals.

1. First Embodiment 1-1. Example of the Configuration of an Architectural Structure First, an architectural structure according to a first embodiment (hereinafter referred to as "this example") will be described with reference to FIGS. 1 and 2. FIG.
Fig. 1 is a plan view showing an architectural structure, and Fig. 2 is a cross-sectional view taken along line AA shown in Fig. 1.

The architectural structure 100 shown in Figures 1 and 2 may be, for example, a nuclear power plant. The architectural structure 100 has a first room 101, a second room 102 adjacent to the first room 101, and a shielding door 1. The architectural structure 100 also has a floor 108 and a ceiling 109 made of reinforced concrete.

An opening 110 is formed at the boundary between the first room 101, which indicates the high-dose area, and the second room 102, which indicates the maintenance room. The shielding door 1 is positioned to close the opening 110 in an openable and closable manner.

A first building rail 103 is installed in the first room 101. The first building rail 103 is installed at a predetermined height from the floor 108. The first building rail 103 extends from the first room 101 to the opening 110. A lifting machine M1, an example of a moving object, is movably installed on the first building rail 103.

A second building rail 104 is installed in the second room 102. The second building rail 104 is installed at a predetermined height from the floor 108 to match the installation height of the first building rail 103. The second building rail 104 is positioned at a predetermined distance from the opening 110. The distance between the second building rail 104 and the opening 110 is the length of the shielding door 1, which will be described later. This prevents interference between the shielding door 1 and the second building rail 104 when the shielding door 1, which will be described later, is opened. The first building rail 103 and the second building rail 104 are configured to be connectable to the door rail 3 provided on the shielding door 1, which will be described later.

The opening 110 connecting the first room 101 and the second room 102 is large enough to allow the crane M1 to pass through. The opening 110 is formed at a predetermined height from the floor 108 to match the installation height of the first building side rail 103 and the second building side rail 104. Furthermore, a frame 106 erected from the floor 108 is positioned at the lower end of the opening 110.

The skeleton 106, which represents the door frame, is made of a reinforced concrete structure, just like the floor 108 and ceiling 109. A building-side fitting portion 107 is formed at the upper end of the skeleton 106. The building-side fitting portion 107 is a stepped portion that protrudes from the upper end of the skeleton 106. A shielding door 1 is attached to the skeleton 106 in an openable and closable manner.

1-2. Structure of the Shielding Door Next, the structure of the shielding door 1 will be described with reference to FIGS.
FIG. 3 is a cross-sectional view showing the shielding door 1, and FIG. 4 is a view of the shielding door 1 as seen from the first room 101 side.

As shown in Figures 3 and 4, the shielding door 1 has a door body 2, a door side rail 3, and a hinge 6. The door body 2 is made of reinforced concrete or steel. The door body 2 is formed to a size and shape that will close the opening of the opening 110 in the architectural structure 100. When the shielding door 1 is closed, the upper end of the door body 2 is in contact with or close to the ceiling 109 of the architectural structure 100.

A door-side fitting portion 5 is formed at the lower end of the door body 2. The door-side fitting portion 5 is a stepped portion formed at the lower end of the door body 2. When the shielding door 1 is closed, the door-side fitting portion 5 fits into a building-side fitting portion 107 provided on the frame 106. This prevents radiation from leaking from the first room 101, which is a high-dose area, to the second room 102, which is a maintenance room, through the opening 110 when the shielding door 1 is closed.

When the shielding door 1 is closed, a door-side rail 3 is installed on one side of the door body 2 facing the first room 101. When the shielding door 1 is closed, the door-side rail 3 extends from the lower end to the upper end of one side of the door body 2. When the shielding door 1 is opened, the door-side rail 3 is connected to the first building-side rail 103 and the second building-side rail 104. In this way, in the shielding door 1 of this example, the door-side rail 3 along which the moving object, the lifting machine M1, moves is integrally provided on the door body 2.

A hinge 6 is provided at the bottom end of the door body 2. The hinge 6 is formed on the other side of the door body 2 opposite the side on which the door-side rail 3 is installed, i.e., the side facing the second room 102. One end of the hinge 6 is connected to the side of the frame 106 facing the second room 102. The other end of the hinge 6 is connected to the other side of the door body 2. In this way, by providing the hinge 6 on the other side opposite the first room 101, which is a high-dose area, it is possible to prevent the hinge 6 from being exposed to radiation and suppress deterioration of the hinge 6, which is a moving part, due to radiation.

1-3. Example of Movement of Lifting Machine Next, an example of movement of the lifting machine M1 in the building structure 100 equipped with the shielding door 1 having the above-described configuration will be described with reference to FIGS.
Fig. 5 is a diagram showing a state in which the shielding door 1 is open, Fig. 6 is a diagram showing a state in which the crane M1 has moved, and Fig. 7 is a diagram showing a state in which the shielding door 1 is closed.

The following operational example describes an example in which the lifting machine M1 is moved from the first room 101, which is a high-dose area, to the second room 102, which is a maintenance room, when performing maintenance on the lifting machine M1.

First, as shown in Figure 5, the door body 2 of the shielding door 1 rotates approximately 90 degrees around the hinge 6. That is, the upper end of the door body 2 tilts toward the second room 102. Furthermore, when the door body 2 is opened, the opening 110 connecting the first room 101 and the second room 102 is opened. Because the shielding door 1 can be opened by the weight of the door body 2, the drive mechanism for opening and closing the door body 2 can be made smaller.

The second building rail 104 installed in the second room 102 is installed with only the length of the door body 2 separated from the opening 110. This prevents interference between the second building rail 104 and the door body 2 when the door body 2 is open. The space provided in the second room 102 can be used as a work space when the door body 2 is closed.

When the door body 2 tilts toward the second room 102, the side of the door body 2 that faces the first room 101 when closed, i.e., the side on which the door side rail 3 is provided, faces upward in the vertical direction. When the door body 2 opens, the door side rail 3 extends from the first room 101 toward the second room 102. When the door body 2 has completed opening, one end of the door side rail 3 is connected to the first building side rail 103, and the other end of the door side rail 3 is connected to the second building side rail 104. As a result, the first building side rail 103 and the second building side rail 104 are connected via the door side rail 3.

Because the door body 2 and door-side rail 3 are integrally installed, the door-side rail 3 can be installed when the door body 2 is open. As a result, the lifting machine M1 can be moved easily and smoothly. Furthermore, by closing the door body 2, the door-side rail 3 can also be easily removed.

Once the connection work between the door-side rail 3 and the first building-side rail 103 and second building-side rail 104 is complete, the lifting machine M1 moves from the first room 101 to the second room 102 along the first building-side rail 103, door-side rail 3, and second building-side rail 104, as shown in Figure 6. Once the lifting machine M1 has completed its movement to the second room 102, as shown in Figure 7, the door body 2 of the shielding door 1 is rotated approximately 90 degrees around the hinge 6, and is erected so that one face of the door body 2 is approximately parallel to the vertical direction. This closes the opening 110 by the shielding door 1.

Because the opening 110 connecting the first room 101 and the second room 102 is closed by the screening door 1, workers can safely perform maintenance on the lifting machine M1 in the second room 102. By performing the steps described above, the movement operation of the lifting machine M1 is completed.

As described above, with the shielding door 1 and architectural structure 100 of this example, by providing the door-side rails 3 on the door body 2, when the shielding door 1 is open, the door body 2 can be used as a support for the moving object, the lifting machine M1. Furthermore, because the door body 2 is opened by tilting toward the second room, there is no need to provide door pockets above, below, or to the left and right of the opening 110. As a result, with the shielding door 1 and architectural structure 100 of this example, it is possible to prevent wasted space from being created by door pockets. Furthermore, as described above, when the door body 2 is closed, the space provided in the second room 102 can be used as a work space.

2. Second Embodiment Next, an architectural structure according to a second embodiment will be described with reference to FIGS. 8 and 9. FIG.
Fig. 8 is an enlarged cross-sectional view of the shielding door in the architectural structure according to the second embodiment. Fig. 9 is a view of the shielding door in the architectural structure according to the second embodiment as seen from the first room side.

The architectural structure 100A according to this second embodiment differs from the architectural structure 100 according to the first embodiment in the configuration of the opening 110 in the door frame of the screening door 1. Therefore, parts that are common to the architectural structure 100 according to the first embodiment are given the same reference numerals and redundant explanations will be omitted.

As shown in Figures 8 and 9, the ceiling 109 on the first room 101 side of the architectural structure 100A has a protruding portion 112. The protruding portion 112 protrudes downward from the ceiling 109 in the vertical direction. Therefore, the height of the ceiling 109 of the first room 101 is lower than the height of the ceiling 109 of the second room 102.

In addition, the height of the ceiling 109 of the second room 102, onto which the door body 2 falls when the shielding door 1 is open, is located higher than the upper end of the door body 2. When the shielding door 1 is closed, a gap is formed between the upper end of the door body 2 and the opening 110. This prevents the door body 2 from interfering with the ceiling 109 when the shielding door 1 is open.

In addition, the lower end of the protrusion 112 is located vertically lower than the upper end of the door body 2 when the shielding door 1 is closed. When the shielding door 1 is closed, the upper end of the door body 2 faces and comes into contact with the surface of the protrusion 112 facing the second room 102. This prevents radiation from leaking from the first room 101 into the second room 102, even if there is a gap between the upper end of the door body 2 and the opening 110.

Other configurations are the same as those of the architectural structure 100 and shielding door 1 according to the first embodiment, so a description thereof will be omitted. The architectural structure 100A and shielding door 1 having such a configuration can also achieve the same effects as those of the architectural structure 100 and shielding door 1 according to the first embodiment described above.

3. Third Embodiment Next, an architectural structure and a shielding door according to a third embodiment will be described with reference to FIGS. 10 to 12. FIG.
Fig. 10 is a cross-sectional view showing the shielding door according to the third embodiment, Fig. 11 is a view showing a state in which the shielding door according to the third embodiment is being opened, and Fig. 12 is a view showing a state in which the shielding door according to the third embodiment has been opened.

The architectural structure 100B and shielding door 1B according to this third embodiment are similar to the shielding door 1 according to the second embodiment, but with a counterweight added. Therefore, parts common to the architectural structures 100, 100A, and shielding door 1 according to the first and second embodiments are given the same reference numerals, and redundant explanations will be omitted.

As shown in Figures 10 to 12, the shielding door 1B comprises a door body 2, a door side rail 3, and a hinge 6. The shielding door 1B also comprises a counterweight 21, a rope 22, and a pulley 23. The pulley 23 is installed on the ceiling 109 of the first room 101. One end of the rope 22 is fixed to one surface of the door body 2 facing the first room 101. The other end of the rope 22 is attached to a counterweight 21. The rope 22 is then wound around the pulley 23 installed on the ceiling 109. The counterweight 21 is set to a weight that balances the door body 2.

Other configurations are the same as those of the architectural structure 100 and shielding door 1 according to the first embodiment, so a description thereof will be omitted. The architectural structure 100B and shielding door 1B having such a configuration can also achieve the same effects as those of the architectural structure 100 and shielding door 1 according to the first embodiment described above.

In addition, according to the shielding door 1B of the third embodiment, a counterweight 21 is connected to the door body 2 via a rope 22. This allows the counterweight 21 to reduce the driving force required to open and close the door body 2.

4. Fourth Embodiment Next, an architectural structure according to a fourth embodiment will be described with reference to FIGS. 13 and 14. FIG.
Fig. 13 is an enlarged cross-sectional view of the shielding door in the architectural structure according to the fourth embodiment. Fig. 14 is a view of the shielding door in the architectural structure according to the fourth embodiment as seen from the first room side.

The architectural structure 100C according to this fourth embodiment differs from the architectural structure 100 according to the first embodiment in the location of the hinge 6 of the screening door 1. Therefore, parts that are common to the architectural structure 100 according to the first embodiment are given the same reference numerals, and duplicate explanations will be omitted.

As shown in Figures 13 and 14, the skeleton 106C, which represents the lower end of the door frame in the architectural structure 100C according to the fourth embodiment, does not have a building-side fitting portion. The shielding door 1C also comprises a door body 2C, a door-side rail 3, and a hinge 6C. One end of the hinge 6C is installed at the upper end of the skeleton 106C. The other end of the hinge 6C is installed on the surface of the door body 2C facing the second room 102. The other end of the hinge 6C is also connected to the middle of the door body 2C in the vertical direction.

A door-side fitting portion 5C is formed at the bottom end of the door body 2C. The door-side fitting portion 5C protrudes downward in the vertical direction from the point where the hinge 6C is connected to the door body 2C. When the shielding door 1 is closed, the door-side fitting portion 5C fits into the surface of the body 106C facing the first room 101. This prevents radiation from leaking from the first room 101, a high-dose area, to the second room 102, a maintenance room, through the opening 110 when the shielding door 1 is closed, even if the hinge 6C is located in the middle of the door body 2C.

Furthermore, even if the hinge 6C is installed at the upper end of the frame 106C, which is the boundary between the first room 101 and the second room 102, the hinge 6C is covered by the door main body 2C and the door-side fitting portion 5C. As a result, the hinge 6C can be prevented from being exposed to radiation, and deterioration of the hinge 6C, which is a moving part, due to radiation can be suppressed.

Other configurations are the same as those of the architectural structure 100 and shielding door 1 according to the first embodiment, so a description thereof will be omitted. The architectural structure 100C and shielding door 1C having such a configuration can also achieve the same effects as those of the architectural structure 100 and shielding door 1 according to the first embodiment described above.

5. Fifth Embodiment Next, an architectural structure according to a fifth embodiment will be described with reference to FIGS. 15 and 16. FIG.
Fig. 15 is an enlarged cross-sectional view of the shielding door in the architectural structure according to the fifth embodiment. Fig. 16 is a diagram showing the shielding door in the open state according to the fifth embodiment. Note that parts common to the architectural structure 100 according to the first embodiment are given the same reference numerals and redundant explanations will be omitted.

As shown in Figures 15 and 16, the architectural structure 100D and shielding door 1D according to the fifth embodiment are the architectural structure 100C and shielding door 1C according to the fourth embodiment, with a counterweight 21 added. The shielding door 1D comprises a door main body 2D, a door-side rail 3, a door-side fitting portion 5D provided on the door main body 2D, and a hinge 6D. One end of the hinge 6D is installed at the upper end of the frame 106D, and the other end of the hinge 6D is installed in the middle of the door main body 2D.

The shielding door 1D also includes a counterweight 21, a rope 22, and a pulley 23 installed on the ceiling 109 of the first room 101. One end of the rope 22 is fixed to one surface of the door body 2D facing the first room 101, and the other end of the rope 22 is connected to the counterweight 21. The rope 22 is then wound around the pulley 23 installed on the ceiling 109.

Other configurations are similar to those of the architectural structure 100 and shielding door 1 according to the first embodiment, and therefore a description thereof will be omitted. The architectural structure 100D and shielding door 1D having such a configuration can also achieve the same effects as the architectural structures 100, 100B, 100C and shielding doors 1, 1B, 1C according to the first, third, and fourth embodiments described above.

The present invention is not limited to the embodiments described above and shown in the drawings, and various modifications are possible without departing from the spirit of the invention as set forth in the claims.
