In a structure in which a movable building such as an elevating roof and an elevating device are integrated, a large seismic force acts on the elevating legs that the elevating device moves up and down in the event of an earthquake. , It is necessary to increase the rigidity of the elevating legs.

In view of the above facts, an object of the present invention is to reduce the seismic force acting on the elevating legs of the elevating device for elevating and lowering a movable building.

The first aspect is a movable building that moves up and down above the arena portion provided with seats around it, an elevating leg that stands around the movable building, and an elevating device that raises and lowers the elevating leg. , A building provided with a seismic isolation device provided on the elevating device and supporting the movable building.

In the building of the first aspect, the elevating device for raising and lowering the elevating legs is provided with a seismic isolation device for supporting the movable building. Therefore, the seismic isolation device provided in the elevating device reduces the shaking of the movable building during an earthquake. Therefore, the seismic force acting on the elevating leg on which the elevating device moves up and down is reduced.

The second aspect is the building according to the first aspect, which has a fixed roof that protrudes above the audience seats and whose tip is supported by the elevating legs.

In the second aspect of the building, the tip of the fixed roof protruding above the audience seats is supported by the elevating legs.

Therefore, it is not necessary to separately provide a support column for supporting the tip of the fixed roof.

Alternatively, the tip of the fixed roof is supported by the elevating legs, which makes the fixed roof less rigid and lighter than the protruding eaves-shaped fixed roof, which has a free end where the tip is not supported. It becomes possible.

In the third aspect, the elevating leg is opposed to each other by forming four columns arranged at positions corresponding to rectangular corners in a plan view and a fixing hole into which a fixing pin for fixing the elevating device is inserted. The building according to the first aspect or the second aspect, comprising a steel plate portion in which an arranged steel plate is joined to the support column and a truss frame portion in which a truss member is joined to the support column.

It is composed of the truss frame and the truss frame.

Therefore, since the steel plate of the steel plate portion of the support portion where the elevating device is supported may be joined to the support column, the construction man-hours can be reduced as compared with the case where the steel plate portion is joined to the support column even in the non-support part where the elevating device is not supported. ..

Alternatively, unlike the case where the elevating leg is made of a steel pipe, there is no waste in making the plate thickness of the non-support portion the same as the plate thickness of the support surface.

Further, as shown in FIGS. 1 and 2, the upper end of the elevating leg 120 is joined to the tip portion 34 of the fixed roof 30. That is, the elevating leg 120 supports the tip portion 34 of the fixed roof 30.

[Elevating process]
Next, the elevating process of the elevating device 150 will be described.

As shown in FIG. 10, the fixing pin 160 of the fixing device 162 of the upper fixing portion 152 is pulled out from the fixing hole 124.

As shown in FIG. 11, the shaft 157 of the hydraulic jack device 156 is extended, the upper fixing portion 152 is lifted, and the fixing pin 160 of the fixing device 162 of the upper fixing portion 152 is inserted into the fixing hole 124. Then, the fixing pin 161 of the fixing device 164 of the lower fixing portion 154 is pulled out from the fixing hole 124.

As shown in FIG. 12, the shaft 157 of the hydraulic jack device 156 is contracted, the lower fixing portion 154 is pulled up, and the fixing pin 161 of the fixing device 164 of the lower fixing portion 154 is inserted into the fixing hole 124.

By repeating these steps, the elevating device 150 climbs the elevating leg 120. Further, by performing these steps in reverse, the elevating device 150 descends from the elevating leg 120.

[Action and effect]
Next, the operation and effect of this embodiment will be described.

In the building 10, the elevating device 150 that elevates and elevates the elevating leg 120 is provided with a laminated rubber bearing 200 that supports the movable pitch 50. Therefore, the laminated rubber bearing 200 provided in the elevating device 150 reduces the shaking of the movable pitch 50 during an earthquake. Therefore, the seismic force acting on the elevating leg 120 on which the elevating device 150 moves up and down is reduced. Therefore, the cross section of the member of the elevating leg 120 can be made smaller as compared with the case where the laminated rubber bearing 200 is not provided.

Then, by reducing the cross section of the member of the elevating leg 120, the construction cost is reduced. Further, by reducing the cross section of the member of the elevating leg 120, the visibility from the audience seat 22 is improved.

Further, since the seismic force transmitted to the movable pitch 50 is reduced, the weight of the movable pitch 50 can be reduced. Further, the rotational deformation acting on the connecting frame 60 and the like is absorbed.

Further, in the building 10, the tip portion 34 of the fixed roof 30 protruding above the audience seat 22 of the stand portion 20 is supported by the elevating legs 120. Therefore, since it is not necessary to separately provide a support column for supporting the tip portion 34 of the fixed roof 30, the construction cost is reduced and the visibility is improved. Alternatively, the fixed roof 30 has lower rigidity than the protruding eaves-shaped fixed roof in which the tip portion 34 of the fixed roof 30 is supported by the elevating leg 120 so that the tip portion 34 is not supported and has a free end. It is possible to make it lighter and lighter.

As described above, the elevating leg 120 has two functions, that is, the function of elevating the elevating device 150 and the function of supporting the fixed roof 30. The fixed roof 30 is lighter than the movable pitch 50, and in the present embodiment, the weight is about 10% or less of the movable pitch 50. Therefore, the cross section of the elevating leg 120 does not need to be increased, or It is possible to support the fixed roof 30 with little increase.

Further, in the building 10, the elevating leg 120 includes a steel plate portion 128 in which a fixing hole 124 into which a fixing pin 160 for fixing the elevating device 150 is inserted is formed and steel plates 122 arranged opposite to each other are joined to the support column 130. It is composed of a truss frame portion 140 to which a truss member 142 is joined to a support column 130.

Therefore, since the steel plate 122 may be joined to the support column 130 to the support portion where the elevating device 150 is supported, the construction man-hours are reduced as compared with the case where the steel plate 122 is also joined to the non-support portion where the elevating device 150 is not supported. .. Alternatively, unlike the case where the elevating leg 120 is made of a steel pipe, there is no waste in making the plate thickness of the non-support portion the same as the plate thickness of the support portion.

Further, the drive equipment unit 112 is installed in the rear portion 69 on the rear side of the intermediate portion 66 which is joined and supported by the laminated rubber bearing 200 in the connection frame 60. Therefore, the drive device unit 112 and the elevating device 150 move up and down integrally. Therefore, the cable 116 connecting the elevating device 150 and the drive device unit 112 can be shortened and easily handled.

Further, the equipment room 114 is provided at the same height as the intermediate portion in the vertical direction of the elevating leg 120 of the side wall portion 24 of the stand portion 20. Therefore, the cable 118 connecting the drive equipment unit 112 and the equipment room 114 can be shortened, and the cable 118 can be easily handled.

Further, two diagonal members 220 extending in two directions are joined to the upper end portion of the elevating leg 120 and the stand portion 20. Therefore, as compared with the case where the elevating leg 120 is reinforced with a single diagonal member, it is possible to effectively resist the overturning moment acting on the elevating leg 120.
