Description

  The present invention relates to a displacement device.

  Conventionally, the framework scaffold used when constructing a structure was known. In this framework scaffold, a plurality of building frames are connected along the structure and installed on the ground, and then the building frame is fixed to the structure to be used.

  However, if the structure to be constructed is a seismic isolation structure that is constructed on the ground via a seismic isolation device, the seismic isolation is caused by the occurrence of an earthquake with the framework scaffolding fixed to the seismic isolation structure. When the structure is displaced horizontally with respect to the ground, a horizontal displacement force that is horizontally displaced is applied to a plurality of building frames of the framework scaffold, and the framework scaffold may collapse.

  Therefore, a technique for preventing the collapse of the framework scaffold installed in the seismic isolation structure has been proposed (see, for example, Patent Document 1). In the technique of this patent document 1, a horizontal displacement force is generated at the time of an earthquake by sliding a frame scaffold relative to the ground after providing a sliding material at the lower end (part provided on the ground) of the framework scaffold. To prevent the framework scaffold from collapsing.

Intermediate seismic isolation structures with seismic devices are 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. It was. In other words, when installing a framework scaffolding for an intermediate seismic isolation structure, the framework scaffolding is fixed to each of the upper floor side and the lower floor side of the middle 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 that is horizontally displaced is applied to a plurality of building scaffolds.

(Operation)
Next, the operation of the displacement device 300 configured as described above will be described. Specifically, when an earthquake having a seismic intensity equal to or higher than a predetermined seismic intensity occurs, the seismic isolation device (not shown) of the seismic isolation layer 12 in FIG. 1 operates, so that the upper building structure 11 and the lower building structure of the seismic isolation building structure 100 are operated. The seismic isolation device (not shown) of the seismic isolation layer 12 in FIG. 1 does not operate when the body 13 is displaced horizontally with respect to each other, when no earthquake occurs, or when an earthquake smaller than a predetermined seismic intensity occurs. The case where the upper building structure 11 and the lower building structure 13 of the seismic isolation building structure 100 are not displaced in the horizontal direction will be described (the same applies to the second and third embodiments). FIG. 5 is a side view of the displacement device when displaced in the horizontal direction, and FIG. 6 is a part of the base-isolated building structure provided with the scaffold device and the displacement device in a state where the displacement device is displaced in the horizontal direction. FIG.

(Operation-When the seismic isolation device operates and the seismic isolation building structure is displaced horizontally)
When the seismic isolation device (not shown) of the seismic isolation layer 12 in FIG. 1 operates, the upper building structure 11 and the lower building structure 13 of the base isolation building structure 100 are displaced in the horizontal direction. The shear pin 33 in FIG. 4 is broken by the force transmitted from the seismic isolation building structure 100 side to the scaffold device 200 by the displacement, and the temporary fixing of the tip member 32 to the plate member 31 is released, and the tip member 32 and the plate member 31 are released. Are in contact with each other and can be displaced separately in the horizontal direction. In this case, as shown in FIGS. 5 and 6, the upper building 221 is displaced following the upper building structure 11, and the lower building 222 is displaced following the lower building structure 13. Therefore, since it is possible to prevent the bending force of the building frame from being applied to the “upper fixed building frame” and the “lower fixed building frame”, the building frame is prevented from being damaged or broken. It is possible to prevent the scaffold device 200 from collapsing. Further, in this case, since the protruding portion 312 is provided on the plate member 31, the displacement in the horizontal direction of the tip member 32 can be applied to the protruding portion 312, and the tip member 32 is detached from the plate member 31. This can be prevented.

(Operation-When the seismic isolation device does not operate and the seismic isolation building structure does not move horizontally)
If 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 are not displaced horizontally from each other, Although no force is transmitted from the seismic building structure 100 side to the scaffold device 200, in this case, since the shear pin 33 in FIG. 4 temporarily fixes the tip member 32 to the plate member 31, the upper building site The 221 and the lower building 222 can be fixed to each other, and the scaffold device 200 can be fixed to ensure safety. Thus, the operation of the displacement device 300 is finished.

(Effect of this embodiment)
According to the present embodiment, the upper building 221 and the lower building 222 are horizontally displaced between each other in accordance with the horizontal displacement between the lower building structure 13 and the upper building structure 11. Similarly, by providing the plate member 31 provided between the upper building 221 and the lower building 222, for example, the upper building 221 and the lower building 222 are horizontally displaced between each other. The scaffold device 200 can be made to follow the horizontal displacement of the base-isolated building structure 100, and the scaffold device 200 can be prevented from collapsing. Furthermore, since the upper building 221 side is configured to contact the outer surface of the plate member 31, for example, the upper building 221 and the plate member 31 can be transported while being separated from each other. The portability of 31 can be improved.

  The tip member 32 contacts the outer surface of the plate member 31 such that the plate member 31 is fixed to the lower building 222 and the upper building 221 is supported with respect to the lower building 222. For example, when the scaffold device 200 is installed (when the displacement device 300 is installed), the scaffold device is generally directed from the lower side (−Z direction) to the upper side (+ Z direction). 200, the upper building 221 that is lighter than the lower building 222 to which the plate member 31 is fixed is positioned on the lower building 222 in this assembly. Therefore, positioning can be performed with a relatively small force, and the scaffold device 200 can be easily installed.

  Further, by providing the flat plate portion 311 parallel to the horizontal direction, for example, the tip member 32 can be smoothly slid, so that the scaffold device 200 can be reliably prevented from collapsing.

(Configuration-Displacement device)
The displacement device 400 of FIG. 7 is the above-described displacement device, and is provided, for example, between the “upper fixed building frame” and the “lower fixed building frame”. For example, a plurality of the displacement devices 400 are provided, but the plurality of displacement devices 400 can be configured in the same manner, and therefore, description will be given focusing on one displacement device 400. The displacement device 400 includes, for example, the first plate member 41 and the second plate member 42 of FIG. One of the first plate member 41 and the second plate member 42 corresponds to a displacement member, and the other corresponds to an opposing displacement member.

(Configuration-Displacement device-First plate member)
The first plate member 41 is the aforementioned displacement means. Although the specific kind and structure of this 1st plate member 41 are arbitrary, for example, it is attached to the upper building 221 and fixed, and the upper building 221 with respect to the lower building 222 So that the exposed lower surface (the surface in the −Z direction) of the first plate member 41 is in contact with the exposed upper surface (the outer surface) of the second plate member 42 (the surface in the + Z direction). And is made of metal, and includes a first flat plate portion 411 and a first plate member side mounting portion 412.

In addition, about this 1st flat plate part 411, although the thing of arbitrary diameters can be used, here, for example, at the time of the occurrence of an earthquake having a predetermined seismic intensity (which can be arbitrarily selected, for example, seismic intensity 3) or more The seismic isolation device (not shown) of the seismic isolation layer 12 in FIG. 7 operates to displace the upper building structure 11 and the lower building structure 13 of the base isolation building structure 100 from each other in the horizontal direction. After determining (estimating) the maximum displacement amount (hereinafter referred to as the maximum displacement amount by the seismic isolation device) based on experiments, simulations, etc., the possible displacement amount D1 in FIG. A diameter larger than the “maximum displacement amount by the seismic device” is calculated, and the diameter determined is used (the same applies to the second flat plate portion 421 described later). Note that the “possible displacement amount” D1 in FIG. 10 is the maximum amount allowable as the horizontal displacement between the first plate member 41 and the second plate member 42, and specifically, an arbitrary reference. For example, as shown in FIG. 10 (a), when viewed from the vertical direction (Z-axis direction), the lower side of the upper building 221 (−Z direction) In the case where the two flat plate portions 421 are present and the first flat plate portion 411 is present on the upper side (+ Z direction) of the lower building land 222, the first center point 411a and the first center point 411a in FIG.

(Configuration-Displacement device-Second plate member)
The second plate member 42 is the aforementioned displacement means. The specific type and configuration of the second plate member 42 are arbitrary. For example, the second plate member 42 is attached to and fixed to the lower building 222, and is an upper building with respect to the lower building 222. The exposed upper surface (the surface in the + Z direction) of the second plate member 42 is in contact with the exposed lower surface (the outer surface) (the surface in the −Z direction) of the first plate member 41 so that 221 is supported. Moreover, it is comprised and is a metal thing, The 2nd flat plate part 421 and the 2nd plate member side attaching part 422 are provided.

  The second flat plate portion 421 is, for example, a portion parallel to the horizontal direction (a direction parallel to the XY plane), a portion facing the first flat plate portion 411, and the first flat plate portion 411 is in contact with the second flat plate portion 421. It is a part, is a flat circular part, and is a part having the same shape as the first flat plate part 411.

FIG. 11 is a side view of a part of the base-isolated building structure provided with the scaffold device and the displacement device in a state where the displacement device is displaced in the horizontal direction.

(Operation-When the seismic isolation device operates and the seismic isolation building structure is displaced horizontally)
When the seismic isolation device (not shown) of the seismic isolation layer 12 in FIG. 7 operates, the upper building structure 11 and the lower building structure 13 of the base isolation building structure 100 are displaced in the horizontal direction. The first plate member 41 and the second plate member 42 shown in FIG. 9 come into contact with each other and can be separately displaced in the horizontal direction by the force transmitted from the seismic isolation building structure 100 side to the scaffold device 201 due to the displacement. . In this case, as shown in FIGS. 10 and 11, the upper building 221 is displaced following the upper building structure 11, and the lower building 222 is displaced following the lower building structure 13. Therefore, since it is possible to prevent the bending force of the building frame from being applied to the “upper fixed building frame” and the “lower fixed building frame”, the building frame is prevented from being damaged or broken. It is possible to prevent the scaffold device 201 from collapsing.

Therefore, the lower building 222 side and the upper building 221 side can be smoothly slid to each other, and the scaffold device 201 can be more reliably prevented from collapsing. Further, since the scaffold device 201 can be supported by two flat plate-shaped members (first plate member 41 and second plate member 42), the load can be distributed to these two members. By reducing the thickness of the single member and reducing the weight of the single member, the portability can be improved. In addition, since the first plate member 41 and the second plate member 42 can be displaced from each other in the range where at least part of the first plate member 41 and the second plate member 42 overlap each other, The range in which the device 201 is displaced can be widened, and the diameters of the first plate member 41 and the second plate member 42 can be reduced.

Furthermore, by being configured so that one scaffold structure side of the other scaffold structure of the upper scaffold structure or the lower scaffold structure is in contact with the outer surface of the displacement means, for example, in the other scaffold structure Since the position where one side of the scaffold structure comes into contact is the outer surface of the displacement means, the one scaffold structure side and the displacement means in the other scaffold structure can be transported while being separated from each other. It becomes possible to improve portability.

  According to the displacement device described in Appendix 2, the displacement member is fixed to the lower scaffold structure, and the lower scaffold structure is supported by the lower scaffold structure so that the upper scaffold structure is supported by the lower scaffold structure. Since the scaffold structure side is configured to be in contact with the outer surface of the displacement means, for example, when the scaffold device is installed (when the displacement device is installed), generally, the scaffold device is directed from the lower side toward the upper side. In this assembly, the upper scaffold structure that is lighter than the lower scaffold structure to which the displacement member is fixed may be assembled by positioning the lower scaffold structure. Therefore, positioning can be performed with a relatively small force, and the scaffold device can be easily installed.

  According to the displacement device described in appendix 3, by providing the flat plate portion parallel to the horizontal direction, for example, one scaffold structure side in the other scaffold structure can be smoothly slid, so that the scaffold device can be collapsed. It becomes possible to prevent reliably.

  According to the displacement device described in appendix 4, by providing the holding means, for example, it is possible to prevent the one scaffold structure side of the other scaffold structure from coming off from the flat plate portion, so that the scaffold device can be more reliably collapsed. It becomes possible to prevent.

  According to the displacement device described in appendix 5, by providing the reinforcing means, for example, the flat plate portion can be reinforced, so that the scaffold device can be more reliably prevented from collapsing.

  According to the displacement device described in appendix 6, since the temporary fixing means is provided, for example, when no earthquake occurs, the other scaffold structure side and the one scaffold structure side can be fixed to each other. Can be prevented from moving unintentionally, and the safety of the scaffold device can be improved.

  According to the displacement device described in appendix 7, since the displacement member is fixed to the horizontal member, for example, the entire displacement member can be firmly fixed to the horizontal member, so that the strength of the displacement member is improved. Therefore, the scaffold device can be reliably prevented from collapsing.

  According to the displacement device described in appendix 8, since the displacement member and the opposed displacement member are in contact with each other, for example, the displacement member and the opposed displacement member can be brought into surface contact with each other. The scaffold structure side and the one scaffold structure side can be slid smoothly with respect to each other, and the scaffold device can be more reliably prevented from collapsing. In addition, since the scaffold device can be supported by two plate-shaped members (displacement member and opposing displacement member), the load can be distributed to these two members, and the thickness of one member can be reduced. By reducing the thickness and reducing the weight of the single member, portability can be improved. In addition, since at least a part of the displacement member and the opposing displacement member overlap each other, the one scaffold structure side and the other scaffold structure side can be displaced from each other, so that the scaffold structure is displaced. And the diameters of the displacement member and the opposing displacement member can be reduced.

  According to the displacement device described in appendix 9, the displacement member is along the intersecting direction that intersects the arrangement direction, and the suspension displacement member is configured to contact the outer surface of the displacement member. For example, since the other scaffold structure side and the one scaffold structure side can be slid mutually along the arrangement direction and the direction intersecting the arrangement direction, it is possible to reliably prevent the scaffold device from collapsing. It becomes.

  According to the displacement device described in appendix 10, the scaffold-side connecting portion is connected to the structure-side connecting portion so that horizontal displacement in different directions or different amounts is possible, so that it can be exempted when an earthquake occurs. Since the seismic building structure and the scaffold device can be displaced independently of each other, it is possible to prevent the scaffold device from being deformed or broken due to excessive force. .
