[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a structure such as a dome constituting a space for holding an event, and more particularly to a structure capable of changing a space volume according to the scale of the event to be held.
[0002]
[Prior art]
Conventionally, as a structure for holding an event, there is a structure such as a dome. In this structure, when the space volume to be used is changed according to the scale of the event to be held, a plurality of temporary partition walls are installed in the structure to partition the space in the dome into a predetermined shape. For example, an event space of a scale suitable for an event to be used, such as watching a boxing game or watching a baseball game, is secured.
[0003]
[Problems to be solved by the invention]
However, in the method of partitioning the space in the structural wall with the temporary partition wall, the space in the structure can be divided into two parts depending on the arrangement of the temporary partition wall. It is difficult to separate two areas in a structure separated by a partition wall. In addition, if only a temporary partition wall is used to separate the area, if a fire or other disaster occurs in one area, the smoke or fire easily moves to the adjacent area, which poses a problem in disaster prevention. It is necessary to remove the temporary partition wall when the intended event ends.
[0004]
As described above, there is a problem that two types of events of different types cannot be held at the same time in the above-described conventional structure in which the spatial volume can be changed.
SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a structure in which a space volume can be changed and two different events can be held at the same time.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, a structure capable of changing a space volume according to claim 1 of the present invention defines an outer peripheral structure wall surrounding a predetermined space, and a space in the outer peripheral structure wall; A moving structure wall that is horizontally movable so that the lateral end moves while maintaining a state of sliding contact with or close to the inner wall of the outer peripheral structure wall , and changes the spatial volume of the partitioned area as the movement proceeds. When provided on both sides of said mobile structural walls, comprising a Sakaikabe having one end and the other end portion is supported on the mobile structure walls are detachably fixed to the inner wall of the peripheral structure wall, the said mobile structure The present invention is characterized in that a buffer space for disaster prevention is formed which is surrounded by a lateral end wall surface of a wall, an inner wall of the outer peripheral structure wall, and the boundary wall .
[0006]
According to a second aspect of the present invention, in the configuration according to the first aspect, the boundary wall is rotatably supported by the moving structure wall and can be turned laterally from the moving structure wall. In a closed state, it is detachably fixed to the movable structure wall, and in an open state, the buffer space for disaster prevention is formed .
[0007]
[Action]
In the invention described in claim 1, the space in the outer peripheral structure wall is sectioned into two independent areas by the moving structure wall. Since the moving structure wall is horizontally movable so that its lateral end moves along the inner wall of the outer structure wall, the moving structure wall maintains a state where the inside of the outer structure wall is separated into two sections. You can move as it is. For this reason, by changing the position of the moving structure wall, each of the two areas partitioned by the moving structure wall has its own space volume changed independently of each other.
[0008]
At this time, the boundary wall is extended from the moving structure wall toward the inner wall of the outer structure wall, so that the boundary between the moving structure wall and the outer structure wall near the connecting portion between the moving structure wall and the inner wall of the outer structure wall. A predetermined disaster prevention buffer space surrounded by the direction end portion, the inner wall of the outer peripheral structure, and the boundary wall is secured.
As a result, the two areas can form an independent space for disaster prevention, and two different events can be simultaneously held in one peripheral structure wall. Further, the boundary wall also has a role of hiding a connection portion between the moving structure wall and the outer peripheral structure wall.
[0009]
Since the boundary wall is supported by the moving structure wall, it automatically moves following the movement of the moving structure wall. Therefore, it is not necessary to independently move the position of the boundary wall every time the moving structure wall is moved.
Further, in the invention described in claim 2, since the boundary wall is rotatable in a lateral direction from the moving structure wall, the boundary wall is opened to the outer peripheral structure wall side, so that the above-mentioned disaster prevention is achieved. Buffer space is secured.
[0010]
Further, according to the second aspect of the present invention, the boundary wall can be swung from the outer peripheral structure wall side to the movable structure wall side to close the boundary wall so as to abut or approach the movable structure wall. Thereby, in order to use only the space volume of one area enlarged, even if the moving structure wall is moved until the wall surface side on which the boundary wall is provided is close to the inner surface of the outer peripheral structure wall, The moving structure wall can be brought sufficiently close to the inner wall of the outer circumferential structure wall without the boundary wall becoming an obstacle.
[0011]
Further, the boundary wall has an effect of shaping the space where the boundary wall is provided.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to the drawings.
The structure of the present embodiment has a configuration as shown in FIG. 1 which is a perspective view in which the roof is omitted, and FIG. 2 which is a conceptual diagram of a wall portion of the structure. That is, the outer peripheral structure wall 4 is arranged on the outer periphery of the inner peripheral side structure wall 1 having a substantially annular cross section.
[0013]
The inner peripheral side structural wall 1 is composed of a fixed structural wall 2 and a moving structural wall 3 each having a substantially semi-cylindrical shape, and the end of the fixed structural wall 2 and the end of the moving structural wall 3 are arranged to face each other. By doing so, a predetermined space volume is surrounded.
Further, the moving structure wall 3 is provided with a known wheel mechanism (not shown), and by driving the wheel mechanism, can be horizontally moved outward along a moving rail 16 laid on the ground. I have. The movable structure wall 3 has a double wall structure for soundproofing or the like. Although only two moving rails 16 are shown in the drawing, more rails are actually laid in consideration of the weight of the moving structure wall 3.
[0014]
The outer peripheral structure wall 4 includes a U-shaped structural wall 5 having a substantially U-shaped cross section and a crescent-shaped arc-shaped structural wall 6.
The U-shaped structural wall 5 has a central portion 5a disposed along the outer periphery of the fixed structural wall 2 of the inner peripheral side structural wall 1 and is formed in a semi-cylindrical shape. Portions 5b (hereinafter, referred to as feet) that are continuous with both ends of the central portion 5a extend along the moving direction of the moving structure wall 3, respectively. As a result, the moving structure wall 3 is horizontally moved along the foot 5b while the lateral end portions 3a are kept in sliding contact with or near the inner wall of the foot 5b of the outer circumferential structure wall 4, respectively. It is possible.
[0015]
The arc-shaped structure wall 6 is provided so as to connect between the distal ends of both feet 5b of the U-shaped structure 5. The inner wall surface of the arc-shaped structure wall 6 is opposed to the outer wall surface of the moving structure wall 3 at a predetermined interval in the moving direction of the moving structure wall 3, and the moving structure wall 3 is retracted to the maximum. In this case, the outer wall surface of the moving structure wall 3 can approach the inner wall surface of the arc-shaped structure wall 6.
[0016]
With the above-described configuration, the space having a substantially elliptical cross section surrounded by the outer peripheral structure wall 4 is divided into two areas A and B by the moving structure wall 3, and each area is moved by the moving structure wall 3 moving forward and backward. The air volume of A and B changes.
Further, a pair of boundary walls 7 are attached to the outer wall side of the moving structure wall 3. As shown in FIGS. 3 and 4, one end in the lateral direction of each of the boundary walls 7 is rotatably supported by the moving structure wall 3 via a pair of hinges 8 so as to be pivotable in the lateral direction. . 3 shows a state in which the boundary wall 7 is open, and FIG. 4 shows a state in which the boundary wall 7 is closed.
[0017]
As shown in FIG. 3, the wall shape of the boundary wall 7 has a curved shape along the outer wall of the moving structure wall 3, and when the turning wall is turned to the moving structure wall 3 side, the moving structure wall 3 It can be stored inside.
Further, three lock pin mechanisms 9 are provided on the other end of the boundary wall 7 in the lateral direction. In this lock pin mechanism 9, a lock pin 9a whose axis is horizontal is regulated by a guide member 9b made of a cylindrical member or the like so that it can move only in the axial direction, and can be moved in the axial direction by an electric cylinder 9c. Is configured. By the lock pin mechanism 9, the other end in the lateral direction of the boundary wall 7 is detachably fixed to the outer wall of the movable structure wall 3 in the closed state and to the inner wall of the outer peripheral structure wall 4 in the opened state. Become so.
[0018]
Further, an outrigger lock mechanism 10 is also provided at the lower end of the boundary wall 7. The outrigger lock mechanism 10 is provided with an insert 10a at the lower end of a shaft whose axis is directed up and down, and is a mechanism for raising and lowering the insert 10a by a cylinder device. Then, the insertion wall 10a is inserted into the concave portion 11 formed on the ground, so that the boundary wall 7 is restrained.
[0019]
Further, two wheels 12, 13 are attached to the lower end of the boundary wall 7, and can roll on a predetermined rail 14 laid on the ground. One of the two wheels 12, 13 is a driving wheel, and the driving wheel is driven by an electric motor 15.
The roof (not shown) of the above structure has a pair of pillar members (not shown) arranged at a position C indicated by a dashed line in FIG. 1 and a cylindrical portion 5 a which is a central portion of the U-shaped structural wall 5. The structure is supported by Thus, the moving structure wall 3 can move without supporting the roof.
[0020]
Next, the operation and the like of the above structure will be described.
Here, in the following description, the space between the fixed structure wall 2 of the inner circumferential side structure wall 1 and the moving structure wall 3 in the space surrounded by the outer circumferential structure wall 4 is referred to as an area A. The space between the structural wall 3 and the arc-shaped structural wall 6 is called area B.
In the structure having the above configuration, various events are normally held in the area A, which is a main event space. When different events are to be held in both areas A and B, as shown in FIGS. 1 and 2, a pair of boundary walls 7 are opened in the lateral direction, and the other end in the lateral direction is connected to the outer peripheral structure wall 4. Are locked by the lock mechanism 9 with respect to the inner wall of the foot 5b, and the respective boundary walls 7 are fixed.
[0021]
As a result, between the inner wall of the foot 5b of the U-shaped structure wall 5, the outer peripheral wall of the movable structure wall 3, and the boundary wall 7, which is the connection between the areas A and B defined by the movable structure wall 3, A predetermined buffer space for disaster prevention is formed, and both areas A and B constitute an independent space including for disaster prevention. That is, even if a fire or the like occurs in one area, the buffer space formed by the boundary wall 7 suppresses the movement of the fire or smoke to the other area.
[0022]
As a result, different events can be simultaneously held in both areas A and B at the same time. Needless to say, events associated with both areas A and B may be held, or events in both areas A and B may not be held at the same time.
Further, by expanding the boundary wall 7 toward the space of the area B as described above, the both end portions 3a in the horizontal direction of the moving structure wall 3 are hidden, and the space of the area B is a closed space having a substantially elliptical cross section. It becomes. As a result, the area B becomes a space where independence is emphasized.
[0023]
A large-sized image device such as an image screen may be provided on the surface of the boundary wall 7 facing the arc-shaped structure wall 6 to enable various effects.
In addition, when it is desired to use the space A on the area A side wide, the moving structure wall 3 is retracted by a predetermined amount along the traveling rail 16 as shown in FIG. Enhance the space volume.
[0024]
When the space A on the side of the area A is expanded to the maximum, the respective walls 7 are closed so as to be swiveled toward the moving structure wall 3 and the respective walls 7 are first closed to the outer peripheral surface of the moving structure wall 3. To be stored. Thereafter, as shown in FIG. 6, the moving structure wall 3 is retracted along the moving rail 16 so that the outer wall of the moving structure wall 3 approaches the inner wall of the arc-shaped structure wall 6.
[0025]
As a result, the spatial air volume in the area B becomes close to zero, and the area A can be used in a state where the spatial air volume is maximum. At this time, even when the boundary wall 7 for securing the buffer space is provided as in the above-described embodiment, when the area B is not used, the boundary wall 7 is turned so as to be closed so that the inside of the moving structure wall 3 is closed. And the outer wall of the moving structure wall 3 is brought close to the inner wall of the arc-shaped structure wall 6 as described above, so that the space A in the area A is not obstructed when it is set to the maximum.
[0026]
Since the boundary wall 7 is supported by the moving structure wall 3, the boundary wall 7 moves together only by moving the moving structure wall 3, and the position of the boundary wall 7 is changed every time the moving structure wall 3 is moved. It is not necessary to move the lock, and it is only necessary to temporarily release the lock mechanism with the outer peripheral structure wall 4 provided on the boundary wall 7, and to operate the lock mechanism again after the movement is completed to bring the lock state.
[0027]
In the above embodiment, the moving structure wall 3 horizontally moves in a straight line, and the lateral ends 3a of the moving structure wall 3 move along the feet 5b of the moving structure wall 3, respectively. Although described in the example of the structure, the present invention is not limited to this type of structure. For example, as shown in FIG. Other structures, such as a structure that can move horizontally along the inner periphery of the outer peripheral structure wall 4, that is, pivotally move around the other end 3 d in the lateral direction of the moving structure wall 3. May be. In short, it is only necessary that the moving structure wall 3 has a structure in which two independent areas A and B can be secured, and the spatial volume of the two areas A and B can be changed.
[0028]
Further, in the above-described embodiment, of the two spaces defined by the moving structure wall 3, a structure in which the area A forms a main event space and the area B forms a sub event space will be described. However, the structure is not limited to such a configuration. For example, as shown in FIG. 8, the moving structure wall 3 is formed of a straight wall, and the moving structure wall 3 is divided by the moving structure wall 3. It may be a structure in which spaces have an equal relationship.
[0029]
Here, in the structure shown in FIG. 8, a diagram is shown in which the boundary walls 7 capable of forming a buffer space for disaster prevention are provided on both wall surfaces of the moving structure wall 3, respectively. Alternatively, a structure in which the boundary wall 7 is provided only on one wall surface side may be used.
Further, in all of the above-described embodiments, the boundary wall 7 is pivotally supported on the movable structure wall 3 so as to be pivotable. However, it is not necessarily required to be configured to be pivotable. The boundary wall 7 may be fixed in a state where the boundary wall 7 extends toward the outer peripheral structure wall 4. However, in this case, even if the moving structure wall 3 is moved so that the spatial volume of one area is crushed and the other area is enlarged, the moving structure wall 3 is protruded from the moving structure wall 3 by the projection of the boundary wall 7. The space between the outer peripheral structure wall 4 and the outer peripheral structure wall 4 cannot be reduced, and the maximum space volume of the other area is limited and reduced accordingly.
[0030]
【The invention's effect】
As described above, in the structure of the present invention in which the space volume can be changed, two independent areas in which the space volume can be changed are secured by the moving structure wall, and the space between the two areas is secured by the boundary wall. By forming a buffer space for disaster prevention in the gap between the two, the above two areas become independent spaces for disaster prevention. Therefore, there is an effect that two different events can be simultaneously held within one outer peripheral structure wall.
[0031]
At this time, if the invention described in claim 2 is adopted, the boundary wall is configured to be pivotable, so that the boundary wall can be moved to a position along the moving structure wall. Therefore, in order to minimize the space volume in one area, that is, to maximize the space volume in the opposite area, the moving structure wall is moved, and the wall surface is brought closer to the outer peripheral structure wall. However, there is an effect that the two walls can be approached to each other without obstructing the boundary wall, and it is possible to effectively set and use only the spatial volume of one area to the maximum amount.
