Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a retractable roof suitable for making an athletic stadium, a baseball stadium and the like all weather type.

<< Conventional Technology >> Generally, all the conventional openable roofs have a laminated structure in which roofs are stacked in several stages, and these are slid or run in a sliding manner to open and close the top of a building.

For example, there has been a method in which a traveling wheel is mounted on a beam for supporting a roof to run a roof member in a beam shape, or a beam is configured to be extendable and retractable, and is moved and opened and closed together with the roof member.

These are designed so that when the movable roofs are opened, they are overlapped with each other to increase the area of the opening. Similarly, in order to increase the area of the opening, it has been considered to make the openable roof a folding structure.

Each of these openable roofs is movably supported on a top of the outer peripheral wall of the building by a traveling cart or the like.

《Problems to be solved by the invention》 Since the openable roof has a structure as roughly described, the structure becomes complicated in conjunction with the moving mechanism of the roof,
It is necessary to ensure mechanical dimensional accuracy.

In addition, in order to move the roof, it is desired that the roof itself be made as small as possible while simultaneously reducing the weight of the roof itself and obtaining a wide aperture ratio.
For this purpose, the roof member is movably supported on the top of the building.

In other words, because the moving roof is located at a very high position from the ground, if it receives an earthquake input or vibration during opening and closing, the roof will shake greatly, and the roof support structure must be designed with special consideration. I had to.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a retractable roof that is resistant to earthquake input.

<< Means for Solving the Problems >> In order to achieve the above object, a retractable roof according to the present invention includes a fixed roof that covers a part of an upper opening of a building having an outer wall, and a movable roof that moves with respect to the fixed roof. A support structure comprising a plurality of movable roofs for opening and closing the opening, the support structure being provided on an upper edge of the outer wall and supporting the fixed roof and the plurality of movable roofs collectively; And a seismic isolation device disposed between the body and the outer wall.

Further, in order to obtain a simple seismic isolation structure, it is preferable that the seismic isolation device is formed of a seismic isolation bearing such as a laminated rubber bearing.

<< Operation >> The openable roof according to the present invention has a seismic isolation structure by providing a seismic isolation device between the fixed roof and a plurality of movable roofs in a lump, and a seismic isolation device between the roof and the outer wall. In addition, it is possible to reduce the transmission of vibration caused by an earthquake, wind, or the like to the openable roof.

In particular, in order to support the ring-shaped support structure that supports the fixed roof and all of the movable roofs collectively with the seismic isolation device provided between it and the outer wall, all the roofs are collectively used during an earthquake. That the roofs do not oscillate in separate cycles during seismic isolation, the relative positions of the roofs can be kept constant, and the adjacent roofs collide There is no.

In addition, the seismic isolation device does not have a vibration control structure that works actively against the earthquake input to eliminate the effect of the earthquake input, but instead receives the earthquake input negatively and adjusts to the natural periodic vibration of the earthquake input. It is preferable to use one that eliminates a vibration input due to an earthquake or a mechanical vibration input due to wind or the like by a resonance action having a phase difference of 180 degrees.

<< Embodiment >> Preferred embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 2 shows a state in which the openable dome roof 1 is removed, seismic isolation bearings 4 are arranged at regular intervals on the top of the outer wall 2, and an arena 8 for playing baseball at an eccentric position inside the outer wall 2. An audience seat 9 is provided so as to fill the space between the arena 8 and the inner wall surface of the outer wall 2. The seismic isolation bearing 4 disposed on the top of the outer wall 2 is provided at the upper edge of the outer wall 2 and supports a support structure that supports the fixed roof 5, the rotating roof 6, and the swiveling roof 7 all together. The support structure includes a track bed for swiveling the swing roof 7. The details are shown in FIG.

As shown in FIG. 3, the seismic isolation bearings 4 are arranged on the top of the outer wall 2 so as to run in the circumferential direction.
A joining material 10 is fixed to the top of the seismic isolation bearing 4 so as to pass the seismic isolation bearing 4 to the book. The seismic isolation bearing 4 has a structure in which steel plates and rubbers are alternately stacked, and the seismic isolation bearing 4 blocks an earthquake input or the like acting on the outer wall 2. A number of pillars 11 are erected in the lateral direction on the joint 10, and a brace 12 is passed between these pillars 11 to reinforce the pillars 11.

The pillar material 11 supports a track bed main member 13 also serving as a sleeper, and a rail 14 is provided on the track bed main member 13. In this manner, the swing roof 6 and the swing roof 7 can be supported by the seismic isolation bearing 4. In other words, the pillars 11 and braces 12 formed on the seismic isolation bearings 4 are steel structures for supporting the track floor consisting of the main track material 13 and the rails 14, but the rust prevention treatment of steel frames and maintenance thereof are simplified. For the purpose of the above, it may be as shown in FIG.
