In the case of a structure relocation, the load of the building is supported by jacks that have been jacked up. However, if there are few support points, there is a risk of instability when moving the building.

In view of the above facts, it is an object of the present invention to increase the support points of the building at the time of the structure relocation.

The first aspect is a cloth foundation step of constructing a cloth foundation in a direction of moving the building from a footing that supports the building, and the footing or the cloth foundation is jacked up by separating the building from the footing and using the footing or the cloth foundation as a support receiver for a jack. This is a structure relocation method including a jack-up process for moving the building and a moving process for moving the building.

In the first aspect of the structure relocation method , the cloth foundation constructed in the direction of moving the building from the footing supports the jack when moving the building, so that the number of support points for supporting the jack increases. By increasing the number of support points, the moving building can be stably supported by the jack, and as a result, the movement of the building is stable and the movement can be performed smoothly.

The second aspect is the structure relocation method according to the first aspect , wherein in the cloth foundation step, the footings are connected by the cloth foundation.

In the second aspect of the structure relocation method , by connecting the footings with a cloth foundation, the support points are increased and the rigidity of the cloth foundation is increased. Therefore, the movement of the building is more stable and can be performed more smoothly.

The third aspect is the structure relocation method according to the first or second aspect , which comprises a seismic isolation repair step of installing a seismic isolation device after the jack-up step.

In the third aspect of the structure relocation method , there is no need for a separate jack-up work when performing seismic isolation repairs.

According to the present invention, it is possible to increase the support points of the building at the time of the towing house.

<Embodiment>
The structure relocation method of the present embodiment will be described.

[building]
First, the building before the towing house and the building after the towing house will be described. The two directions orthogonal to each other in the horizontal direction are the X direction and the Y direction, and are indicated by arrows X and Y, respectively. Further, the vertical direction is the Z direction, which is indicated by an arrow Z. In addition, the direction in which the building is moved (hereinafter referred to as the "structure relocation direction") is indicated by the arrow HK as the HK direction. The HK direction, which is the towing direction, is one of the X directions.

As shown in FIG. 1 (A), the building 10 before being towed is supported by the footing 50 in which the pillar 12 is constructed on the ground 20 (see also FIGS. 2 (A) and 5 (A)). ).

As shown in FIG. 2A, the towed and seismically isolated building 10 is supported by a cloth foundation 100 connecting the footing 50 and the footing 50 (also in FIG. 4B). reference). Specifically, a seismic isolation device 30 such as laminated rubber is installed on the cloth foundation 100, and the pillar 12 of the building 10 is supported by the seismic isolation device 30 (see also FIG. 4B). Further, a foundation beam 40 is provided above the seismic isolation device 30 in the pillar 12 (see also FIG. 4B).

The footing 50 and the cloth foundation 100 of the present embodiment are made of reinforced concrete, but are not limited thereto.

[Structure process]
Next, an example of the structure relocation process will be described.

First, as shown in FIGS. 2 (A), 2 (B), 5 (A) and 5 (B), the cloth foundation 100 (FIG. 2 (B) and FIG. FIG. 5B) is constructed, and the footing 50 and the footing 50 are connected by a cloth foundation 100 (see FIGS. 2B and 5B).

As shown in FIG. 3 (A), the lowermost beam 14 (see FIGS. 1 (A), 2 (A) and 2 (B)) is cut and removed, and the jack receiver 110 is attached to the pillar 12. Installation, as shown in FIGS. 3 (A) and 6 (A), a jack 120 is installed between the footing 50 and the jack receiver 110 (see FIG. 3 (A)), and the jack 120 is used for the building 10 (pillar 12). ). A moving member such as a roller (not shown) is installed in advance on the lower side of the jack 120.

As shown in FIG. 3B, the lower end portion 12A of the pillar 12 (see FIG. 3A) is cut and cut while being supported by the jack 120, and the building 10 (pillar 12) is separated from the footing 50.

As shown in FIGS. 4 (A) and 6 (B), with the building 10 jacked up by the jack 120, each jack 120 installed on a moving member such as a roller (not shown) is directed toward the structure relocation. Move the building 10 in the HK direction). At this time, the jack 120 moves on the cloth foundation 100.

Further, as shown in FIG. 4A, the seismic isolation device 30 is installed on the cloth foundation 100 at the moving destination, jacked down, and the pillar 12 is connected to and supported by the seismic isolation device 30.

As shown in FIGS. 2 and 4B, moving members such as rollers (not shown), a jack 120 and a jack receiver 110 (see FIG. 4A) are removed, and a foundation beam 40 is provided on the pillar 12.

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

The cloth foundation 100 constructed in the direction of the structure relocation (HK direction) for moving the building 10 from the footing 50 supports the jack 120 when the building 10 is moved, so that the number of support points for supporting the jack 120 increases. By increasing the number of support points, the moving building 10 can be stably supported by the jack 120, and as a result, the movement of the building 10 is stable and the movement can be smoothly performed.

Further, by connecting the footing 50 and the footing 50 with the cloth foundation 100, the support points are increased and the rigidity of the cloth foundation 100 is increased. Therefore, the movement of the building 10 is more stable and can be performed more smoothly.

Further, by installing the seismic isolation device 30 on the cloth foundation 100 at the moving destination, jacking down and connecting the pillars 12 to support them, there is no need to separately jack up at the time of seismic isolation repair. Therefore, the construction manpower is reduced.

<Others>
The present invention is not limited to the above embodiment.

For example, in the above embodiment, the footing 50 and the footing 50 are connected by a cloth foundation 100, but the present invention is not limited to this. There may be a gap between the footing 50 on the downstream side in the structure relocation direction (HK direction) and the end portion on the downstream side of the cloth foundation 100.

Further, in the above embodiment, the cloth foundation 100 is constructed only in the direction from the footing 50 to the structure relocation (HK direction), but the present invention is not limited to this. The cloth foundation 100 may be constructed from the footing 50 in the direction opposite to the towing direction (HK direction), or the cloth foundation 100 may be constructed from the footing 50 in the Y direction orthogonal to the towing direction (HK direction). ..

Further, in the above embodiment, in FIGS. 3 and 6A, the jack 120 is supported only by the footing 50, but is not limited thereto. The jack 120 may be supported by the cloth foundation 100.

Further, for example, in the above embodiment, both the structure relocation and the seismic isolation repair are performed, but the present invention is not limited to this. You may only go to the structure relocation.

Needless to say, it can be carried out in various embodiments without departing from the gist of the present invention.
