[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dome roof facility such as a multipurpose arena in which a large indoor space is formed by a dome roof, and more particularly to a dome roof facility that effectively utilizes a space around the dome roof so that it can be used for multiple purposes.

[0002]

2. Description of the Related Art Conventionally, there is known a dome-type baseball stadium which is designed mainly for baseball and can be used as a stadium for soccer, rugby, American football, etc. by partially rearranging the seat layout. . The basic structure of this type of facility is to construct a cylindrical base structure mainly composed of steel-framed reinforced concrete structures, provide a seat on the inner side of the structure, surround the ground, and place it on the base structure. It has dome roofs of various structures.

[0003]

The inside of the above-mentioned basic structure (stand structure) is formed in a multi-level structure, and entrances and passages leading to the seats are formed, and a store such as a stand is provided. Furthermore, various auxiliary facilities such as an air conditioning system and a power supply system are provided.

[0004] A dome roof having a form in which a bowl is laid down is connected to the stand structure, but there is a large unused space on the outer peripheral portion of the dome roof.

The present invention has been made by paying attention to the above-mentioned unused space in the outer peripheral portion of the dome roof. This space is effectively utilized to realize a dome roof facility of a novel shape which has not existed in the past. The goal is to realize a dome roof facility as a multifunctional facility that has a space for another function or purpose, in addition to the large space surrounded by.

[0006]

The dome roof facility according to the present invention is a cylindrical basic structure, in which various incidental facilities are provided in a multi-level space inside the structure, and a multi-level structure is provided on the inner peripheral side. A stand structure provided with a multi-level seat, and a dome roof covering the upper part of the large space surrounded by the stand structure, the outer periphery of which is joined to the upper end of the inner periphery of the stand structure and which is entirely supported by the stand structure And an arcade attached to the roof slab of the stand structure and forming a donut-shaped passage around the outer periphery of the dome roof.

[0007]

By providing an arch on the roof slab of the stand structure and forming the arcade, a wide passage without pillars is formed around the outer periphery of the dome roof, thereby facilitating the flow of a large amount of people. In addition to this, it is also possible to provide a number of stores in this passage.

[0008]

1 to 3 show the configuration of a dome roof facility according to an embodiment of the present invention. The dome roof of this embodiment is a steel dome with a diameter of 165 m and a rise of about 43 m,
A dome main body 1 having a diameter of 134 m, a dome leg 2 at an outer peripheral portion thereof, and a dome top 3 composed of a 45 m diameter system truss combined with a top of the dome main body 1.
Consists of three parts. In addition, the lower structure on the ground side that supports the dome roof consisting of these three parts,
This is a cylindrical stand structure 4 mainly composed of a steel-framed reinforced concrete structure provided with a multi-layered seat 5 on the inner peripheral side.

The dome body 1 has a steel truss structure using a section steel such as a roll H section steel or a CT section steel, and forms a compressive stress field in both the radial direction and the circumferential direction. A compression ring 1a is added to the innermost peripheral portion of the dome body 1, and a compression ring 1b is also added to the outermost peripheral portion. Each of the compression rings 1a and 1b is an annular member for processing a horizontal component of the internal force of the dome curved surface, and generates a compressive stress in a cross section of the member. The dome top 3 is made of a lightweight system truss centered on a quadrangular pyramid unit composed of a steel pipe and a node, and is connected to the innermost compression ring 1 a of the dome body 1 by fitting its outermost periphery to the compression ring 1 a. The dome top 3 is provided with a perforated outer panel, a glass skylight, and a louver to allow natural ventilation and natural daylighting.

The stand structure 4 employs a twin column structure in which two columns 6a and 6b combined in a substantially X-shape are employed, and the main structure is a steel reinforced concrete structure. A large number of twin columns 6a, 6b are constructed on the circumference at regular intervals, and the large number of twin columns 6a, 6b are integrally connected by floor slabs 6c and beams 6d. An SRC load-bearing wall 6e with a built-in steel plate is provided in the most constricted portion in the middle of the twin columns 6a and 6b, so that sufficient strength and deformability are provided. In addition, the seat 5 adopts a precast plate, and the floor taken out has a structure in which a synthetic floor plate is arranged on a steel frame to reduce the weight of the building and shorten the construction period.

[0011] The dome leg 2 is formed by connecting two steel members substantially in Y.
It is composed of a large number of pillars 7 combined in a letter shape and integrated. The pillars 7 are arranged radially at a constant pitch facing obliquely upward toward the center of the dome, and the lower end of the pillar 7 is connected to the inner peripheral upper end of the stand structure 4. The dome body 1 is connected to the outermost compression ring 1b. The connecting portions between the pillars 7 and the stand structure 4 are mutually connected in the circumferential direction by a tension ring 8. The connection point between the pillar 7 and the compression ring 1b and the connection point between the pillar 7 and the tension ring 8 are each connected by a pin, and are rotatable around a horizontal pin.

As shown in FIG. 2, the inclination angle of each pillar 7 of the dome leg 2 as viewed from the center of the dome is smaller than the inclination of the outermost peripheral dome curved surface of the dome body 1. The dome roof has a gentle skirt. Therefore, the weight of the dome roof is
Is transmitted evenly to the lower stand structure 4 via.
Since the connecting points of the pillars 7 in the stand structure are circumferentially connected by the tension ring 8, the horizontal force (acting in the direction of increasing the diameter) transmitted from the dome leg 2 to the stand structure 4 is tensioned. It is effectively received by the ring 8. That is, the horizontal force from the dome roof is suppressed by the hoop tension effect of the tension ring 8, so that the stand structure 5 does not need to bear a large horizontal force acting from the dome roof.

As shown in detail in FIG. 3, outer panels 10 and 11 and the like are attached to the outer peripheral side of the stand structure 4 using a support frame 12 and the like to form the appearance of the building. The stand structure 4 has a nine-layer structure, and also communicates with multi-level seats 5. The internal space of each floor is used as a passage, a store, a power supply room, or an air conditioning room.

The distance between the upper ends of the twin columns 6a and 6b constituting the stand structure 4 is large, and the roof slab 13 constructed in this portion has a wide circular shape surrounding the outer periphery of the dome leg 2. Makes up the floor. An arch 14 is installed using the support frame 12 or the like so as to cover the space above the roof slab 13, and the space surrounded by the arch 14 is an arcade 15.

The arch 14 is about 6 m wide assembled from H-section steel.
The unit frame has a belt-like semicircle, and is installed at an appropriate interval on the roof slab 13 of the stand structure 4 over the entire circumference. An appropriate outer panel is attached to the arch 14, and the arcade 15 is an all-weather passage.

In the embodiment shown in FIG.
A transparent panel is disposed at an appropriate interval as an outer panel 5 and the inside of the arcade 15 is naturally lit. Also, as shown in FIG. 1, the height of the arch 14 is gradually increased in the arrangement direction,
The arcade 15 is gradually reduced so that the appearance of the arcade 15 becomes a waveform. In addition to being able to enter and exit the arcade 15 by stairs, escalators, elevators, and the like inside the stand structure 4, an escalator 16 that reaches the arcade 15 directly from the outside may be provided as shown in FIG.

[0017]

As described in detail above, according to the present invention, an arcade is provided on a roof slab of a cylindrical stand structure for supporting a dome roof, and a donut-shaped all-weather type is provided around the outer periphery of the dome roof. Because the multi-purpose passage is formed, the unused space existing around the dome roof can be effectively used, and not only the inside of the dome but also a long donut-shaped arcade can be used variously as a sub venue. In addition, the appearance of the whole facility will be a new and unprecedented form.
