Abstract

PROBLEM TO BE SOLVED: To make an openable roof lightweight, stabilize a whole structure and reduce space required for a structure. SOLUTION: A roof along the direction of height has a thin and minimum required truss structure, and column members 11 are formed as a nest box housing type to be used for adjacent roof units 15 in common. Also, structural breadth with the required breadth of a both-end lower structure added to structural height and internal space breadth is substantially reduced as a whole structure for reducing structural member length and steel frame weight. At the same time, the structural height of the whole structure is kept small for reducing overturning moment due to a horizontal load such as the wind and the earthquake, thereby increasing stability and reducing the reaction forces of a truck 16 and a drive truck 24. Furthermore, ground rails 17 are such that one rail is laid at one side, thereby substantially reducing breadth dedicated to the rails 17.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retractable roof structure used in a multipurpose ball stadium or the like.

[0002]

2. Description of the Related Art FIGS. 11 and 12 show an example of a conventional retractable open / close roof structure used in a multipurpose ball stadium or the like. FIG.
1 shows an overall perspective view of a conventional openable / closable roof structure, and FIG. 12 shows a cross section in a state where the roof is opened.

As shown in the figure, five sets of roof units 3 each composed of four pillar members 1 and a roof member 2 are provided. A bogie 4 is provided below the column member 1 of each roof unit 3.
Are provided, and the carriage 4 is movable along a ground rail 5 provided for each roof unit 3.
Each of the roof units 3 is sequentially formed with a large structure height and a large structure width (toward the left side in FIG. 11) so as to be sequentially housed in the adjacent roof units 3 without interference.

[0004] In the illustrated open / close roof structure, when the multipurpose ball stadium is used in rainy weather or the like, the bogie 4 is moved along the ground rail 5.
Is moved, and the roof units 3 are arranged side by side so that the roof is closed. When the multi-purpose ball stadium is used outdoors, the carriage 4 is moved along the ground rail 5 and each roof unit 3 is sequentially stored in the adjacent roof unit 3 so that the largest roof unit 3 can be used.
The roof is opened by storing all the roof units 3 in the part.

[0005]

In the conventional openable roof structure, as shown in FIG. 12, it is necessary for the individual roof units 3 to be housed without interfering with each other in height and width. As a whole structure for obtaining a proper internal space width b × h, a large structural height H and a structural width B obtained by adding the required lower structure widths b _sub at both ends to the internal space width b are required.

In addition, since the overall structural height H is large, the overturning moment due to a horizontal load such as a wind or an earthquake has a large value. Such an increase in the member length or the overturning moment has resulted in an increase in the steel frame weight of the structure. In addition, the number of trolleys 4 also requires the number of pillar members 1 (at least four) for each roof unit 3, and a drive mechanism is also required for each roof unit 3. Furthermore, the number of ground rails 5 is also required for each roof unit 3 that is overlapped during storage, and the required lower structural space is increased in accordance with the number of ground rails 5.

[0007]

In order to achieve the above object, the present invention comprises a plurality of roof units each including a column member and a roof member, and each of the plurality of roof units is movably supported. In an openable and closable roof structure which is sequentially housed inside the adjacent roof unit, a unit is formed by a pair of pillar members and beams, and the unit includes a plurality of roof units constructed by supporting one end of the roof member. , Each of the plurality of roof units is movably supported, the height of the column members of the adjacent roof unit is sequentially reduced, and the other end of the roof member is the upper surface of the roof member of the adjacent roof unit.

Characterized in that a fixing means for fixing the roof unit adjacent in.

[0008]

1 is an overall perspective view of an open / close roof structure according to an embodiment of the present invention, FIG. 2 is a cross-sectional view of the open roof, FIG. FIG. 4 shows the mechanism concept when the roof is closed and when the roof is opened.

As shown in FIGS. 1 and 3, one unit is formed by a pair of column members 11 and beams 12, and one end of a roof member 14 is integrally supported on the unit to form a roof unit 15. Have been. That is, only the surface where the column member 11 is located is a large truss beam having a large structural height. Four sets of roof units 15 are provided, and carts 16 are provided below the pillar members 11 of the respective roof units 15, and each cart 16 is movable along a common ground rail 17.

The height of the pillar members 11 of the adjacent roof unit 15 is gradually reduced (to the right in the drawing),
The other end of 4 is movably supported on the upper surface of the roof member 14 of the adjacent roof unit 15 via a roof carriage 18 and a roof rail 19. In other words, the pillar members 11 and the beams 12 are shared between the adjacent roof units 15 to support the load of the adjacent roof member 14, and the structure of the general part of the roof member 14 is a minimum necessary small truss structure. .

An end roof unit 23 having four column members 20 and a roof member 21 and having a column brace 22 is provided adjacent to the end roof unit 15. The height is set to the lowest. Driving carts 24 are provided below the four pillar members 20, respectively. The driving carts 24 are movable along the ground rails 17. On the upper surface of the roof member 21, the roof member 14 of the adjacent roof unit 15 is
8 and movably supported via a roof rail 19.

In order to ensure stability against horizontal loads, individual roof units 15 and end roof units 23
A fixing means 25 (for example, a lock pin) is provided on the roof bogie 18 to ensure the transmission of a load between the horizontal shift and the upshift. Further, fixing means 26 (for example, a lock pin) is also provided on the cart 16 and the drive cart 24, so that the horizontal force between the individual roof units 15 and the end roof units 23 and the load transmission to the upshift are ensured. I have.

Each of the roof unit 15 and the end roof unit 23 is nested so that the pillar surface is a common surface (see FIG. 4). The number can be reduced, and the number of ground rails 17 can be reduced to one per side. FIG. 4A shows a state in which the roof is fully closed (at the time of expansion).
(b) is a state in which the roof is fully opened (when stored). For this reason, as shown in FIG. 2, as a whole structure for obtaining a necessary internal space width b × h, the lower structure required width b _sub at both ends is added to the structural height H and the internal space width b. The structure width B becomes very compact.

As shown in FIG. 5, the horizontal force at the time of earthquake caused by the roof load is H _{R1 to} H _R5, and the horizontal force at the time of earthquake caused by the column load is H _{C1 to} H _C5 . With respect to the horizontal force at the time of an earthquake, the horizontal fulcrum reaction force R _H5 via the fixing means 26 on the bogie 16 and the driving bogie 24 side by the end roof unit 23 having the column braces 22 provided to increase the horizontal rigidity. , R _H6 and the vertical fulcrum reaction forces R _V5 , R _V6 generated as a couple of the overturning moment.

The approximate value of the fulcrum reaction force against the seismic force is shown below.

(Equation 1)

Similarly, in the direction orthogonal to the ground rail 17, horizontal force is transmitted by the fixing means 26, and the gate-type rigid frame composed of columns and roof truss beams resists horizontal force in the event of an earthquake.

As an example of the use of the above-mentioned open / close roof structure, FIG. 6 schematically shows a situation where the above-mentioned open / close roof structure is used as an open / close roof 32 of a multipurpose ball stadium 31. FIG. 6 (a) shows a plan view with the openable roof 32 opened (when the roof is stored), and FIG. 6 (b) shows a plan view with the openable roof 32 closed (when the roof is expanded). Is shown. End roof unit 23 with column braces 22
Is provided with a driving carriage 24, and the opening and closing roof 32 is opened and closed by driving movement of the driving carriage 24.

FIG. 7 shows the movement of the end roof unit 23 and the roof unit 15 when the openable roof 32 is closed.

FIG. 7 shows a state in which the roof is fully opened in the storage place. When the roof is fully closed from this state, the roof is closed in the order of FIG. 7 to FIG. That is, FIG. 7 shows the state of the entire movement, and FIGS.
When the roof unit 15 at the rear in the traveling direction sequentially reaches the predetermined position in this order, the fixing means 26 is acted on the drive cart 24 and the car 16, and the fixing means 25 is acted on the roof car 18 to be fixed. Then, the roof is fully closed in FIG.

The order in which the fixing means 25 and 26 are fixed is set such that the moving load on the roof of the end roof unit 23 and the roof unit 15 is always equal to the load of one unit, and the moving roof load is directly below the roof. The effect on the structure is reduced.

FIG. 8 shows the movement of the end roof unit 23 and the roof unit 15 when the openable roof 32 is opened. FIG. 8 shows a state where the roof is fully closed. When the roof is fully opened from this state, FIG.
7 to 7, the opening / closing roof 32 is stored in the storage place in the order of FIGS.

In the above-mentioned open / close roof structure, the roof height is thin and the truss structure is the minimum necessary.
1 is a nested storage type that is shared between adjacent roof units 15, so that the overall height of the structure is H
In addition, the structure width B obtained by adding the lower structure required widths b _sub at both ends to the internal space width b can be significantly reduced. Further, the length of the member is reduced, and the number of the column members 11 is small, so that the number of members is reduced, so that the weight of the steel frame can be reduced.

Further, since the structural height H of the entire structure can be kept low, the overturning moment with respect to a horizontal load such as a wind or an earthquake can be reduced, so that the stability can be improved, and The reaction force of the drive cart 24 can be reduced. Further, the ground rail 17 can be one rail on each side, and the rail occupation width, which is the required width b _sub of the lower structure, can be significantly reduced.
