Description

The present invention relates to a displacement device.

Conventionally, framework scaffolding used when constructing a structure has been known. In this framework scaffolding, a plurality of building frames were connected along the structure and erected on the ground, and then the building frame was fixed to the structure to be installed and used.

However, if the structure to be built is a seismic isolation structure that is built against the ground via a seismic isolation device, the seismic isolation will occur due to the occurrence of an earthquake with the framework scaffolding fixed to the seismic isolation structure. When the structure is horizontally displaced with respect to the ground, a horizontal displacement force that horizontally displaces the multiple building frames of the framework scaffolding is applied, and the framework scaffolding may collapse.

Therefore, a technique for preventing the collapse of the framework scaffolding installed in the seismic isolation structure has been proposed (see, for example, Patent Document 1). In the technique of Patent Document 1, a sliding material is provided at the lower end of the framework scaffold (a portion provided on the ground), and then the framework scaffold is slid relative to the ground, so that a horizontal displacement force occurs at the time of an earthquake. Was prevented from being given to the framework scaffolding, and the collapse of the framework scaffolding was prevented.

By the way, as the seismic isolation structure, in addition to the conventional seismic isolation device provided between the foundation such as the ground and the structure of the building, the seismic isolation structure is exempted from the middle layer of the structure (for example, the fourth floor part, etc.). An intermediate seismic isolation structure equipped with a seismic device is known. In such an intermediate seismic isolation structure, even if the technique of Patent Document 1 is applied to prevent the collapse of the framework scaffold installed at the time of construction, there is a possibility that the collapse of the framework scaffold cannot be prevented. rice field. That is, when the framework scaffolding is installed for the intermediate seismic isolation structure, the framework scaffolding is fixed to each of the upper floor side and the lower floor side of the intermediate layer where the seismic isolation device is installed. When the upper floor side and the lower floor side of the intermediate layer in the intermediate seismic isolation structure are horizontally displaced from each other due to the occurrence of an earthquake, a horizontal displacement force is applied to the multiple building frames of the framework scaffolding. As a result, it may not be possible to prevent the framework scaffolding from collapsing.

It is possible to prevent the scaffolding device from collapsing. In addition, following the horizontal displacement of the seismic isolation building structure, the upper scaffolding structure and the lower scaffolding structure are displaced horizontally and vertically to bend and deform the scaffolding device (that is, to deform it into a shape that does not easily collapse). This prevents each scaffolding structure of the scaffolding device from being displaced horizontally beyond a predetermined allowable amount of displacement and causing the scaffolding device to undergo shear deformation (that is, deformation into a shape that may collapse).

It is possible to prevent the scaffolding device from collapsing. In addition, following the horizontal displacement of the seismic isolation building structure, the upper scaffolding structure and the lower scaffolding structure are displaced horizontally and vertically to bend and deform the scaffolding device (that is, to deform it into a shape that does not easily collapse). This prevents each scaffolding structure of the scaffolding device from being displaced horizontally beyond a predetermined allowable amount of displacement and causing the scaffolding device to undergo shear deformation (that is, deformation into a shape that may collapse).

(motion)
Next, the operation of the displacement device 300 configured in this way will be described. Specifically, when an earthquake of a predetermined seismic intensity or higher occurs, the seismic isolation device (not shown) of the seismic isolation layer 12 in FIG. 1 operates to operate the upper building structure 11 and the lower building structure of the seismic isolation building structure 100. The seismic isolation device (not shown) of the seismic isolation layer 12 in FIG. 1 does not operate when the body 13 and the body 13 are displaced from each other in the horizontal direction, when an earthquake does not occur, or when an earthquake smaller than a predetermined seismic intensity occurs. A case where the upper building structure 11 and the lower building structure 13 of the seismic isolated building structure 100 are not displaced from each other in the horizontal direction will be described.

(Operation-when the seismic isolation device operates and the seismic isolation building structure is displaced horizontally)
When the upper building structure 11 and the lower building structure 13 of the seismic isolation building structure 100 are displaced in the horizontal direction due to the operation of the seismic isolation device (not shown) of the seismic isolation layer 12 of FIG. Due to the force transmitted from the seismic isolated building structure 100 side to the scaffolding device 200 due to the displacement, the shear pin 35 in FIG. 5 is broken, and the temporary fixing between the first member 31 and the second member 32 is released. The first member 31 and the second member 32 can be displaced from each other via the elastic member 33. The displacement direction here is arbitrary, but for example, it may be displaced in the horizontal direction as shown in FIG. 6, or it may be displaced in the horizontal direction and the vertical direction as shown in FIG. 7. The "horizontal displacement" means that the positions of the first member 31 and the second member 32 deviate in the horizontal direction, and the "vertical displacement" means the vertical direction (Z-axis direction). In the above, the positions of the first member 31 and the second member 32 are displaced. Further, here, the regulating member 34 of FIG. 6 is provided, and when the displacement amount in the horizontal direction becomes a certain value or more, the regulating member 34 hits the inner surface of the first mounting portion 312 of the first member 31. Since further horizontal displacement is restricted, it is prevented that the upper building 221 is displaced from the entire lower building 222 in the vertical direction (Z-axis direction). And here, as shown in FIG. 8, the scaffolding device 200 is deformed by shear deformation (that is, deformation into a shape corresponding to a parallelogram, and may collapse due to displacement by each displacement device 300. Instead of deforming (deforming to), it will be deformed by bending (that is, deformed into a shape that is hard to collapse), and it will be possible to prevent collapse.

(Operation-when the seismic isolation device does not operate and the seismic isolation building structure does not displace horizontally)
When the seismic isolation device (not shown) of the seismic isolation layer 12 in FIG. 1 does not operate and the upper building structure 11 and the lower building structure 13 of the seismic isolation building structure 100 do not displace each other in the horizontal direction, the seismic isolation layer 12 is exempted. The force is not transmitted from the seismic building structure 100 side to the scaffolding device 200, but in this case, the shear pin 35 in FIG. 5 temporarily fixes the first member 31 and the second member 32 to each other. Therefore, the first member 31 and the second member 32 can be in a mutually fixed state, and the scaffolding device 200 can be fixed to ensure safety. This ends the operation of the displacement device 300.

(Effect of this embodiment)
According to the present embodiment, the upper building site 221 of the scaffolding device 200 provided on the upper building structure 11 side and the lower building site 222 of the scaffolding device 200 provided on the lower building structure 13 side. However, the upper building 221 is provided with respect to the lower building 222 so as to be horizontally displaced or vertically displaced between the lower building structure 13 and the upper building structure 11 according to the horizontal displacement between the lower building structure 13 and the upper building structure 11. By elastically supporting, for example, the scaffolding device 200 can be damaged because the upper building 221 and the lower building 222 can be horizontally displaced at least following the horizontal displacement of the seismic isolation building structure 100. It is possible to prevent the scaffolding device 200 from collapsing. Further, following the horizontal displacement of the seismic isolation building structure 100, the upper building 221 and the lower building 222 are horizontally and vertically displaced to bend and deform the scaffolding device 200 (that is, to deform into a shape that is hard to collapse). ), So that each building site 22 of the scaffolding device 200 is displaced in the horizontal direction by exceeding a predetermined allowable displacement amount, and the scaffolding device 200 is deformed by shearing (that is, deformed into a shape that may collapse). This can be prevented and the scaffolding device 200 can be prevented from collapsing.

Further, by providing the elastic member 33 between the lower building 222 and the upper building 221, for example, the weight of the upper building 221 can be reliably supported with respect to the lower building 222. Therefore, it is possible to reliably prevent the scaffolding device 200 from collapsing.

Further, since the displacement device 300 is detachable from the lower building 222 or the upper building 221, for example, the displacement device 300 can be easily installed on the scaffolding device 200, so that the displacement device 300 can be easily installed. It is possible to improve the usability of.

Further, by restricting the horizontal displacement of the lower building 222 and the upper building 221 beyond a predetermined horizontal displacement amount, for example, the lower building 222 and the upper building 221 are horizontal in the horizontal direction. Since it is possible to prevent the relative position from being displaced more than expected, it is possible to more reliably prevent the scaffolding device 200 from collapsing.

Further, by temporarily fixing the upper building 221 side and the side building 222 side to each other, for example, the relative position between the upper building structure 11 side and the lower building structure 13 side changes when an earthquake does not occur. Since it is possible to prevent the scaffolding device 200 from being deformed, it is possible to improve the safety of the scaffolding device 200.
