However, if a force is applied to the building such that the pillars come close to or separate from each other when the whole or a part of the building is lifted or transferred by the transportation means, the foundation frame is used. May be deformed or destroyed, at which time the building will become unusable.

The present invention has been proposed in view of the above problems, and when the foundation frame is lifted to correct the inclination of the building or to transfer the building, the foundation frame is deformed. It is an object of the present invention to provide a reinforced structure for a base frame when a building is moved, which is free of work and improves workability.

[0006]

In order to solve the above-mentioned problems, the reinforcing structure of the base frame for moving a building according to claim 1 is provided when the base frame of the building is separated from the foundation and lifted by a jack to move. It is a reinforcement structure of the base frame when moving the building, and the opposite corners of the base frame are connected by wires. Further, in the reinforcing structure of the base frame for moving a building according to claim 2, a corner shape retainer is attached to a corner of the base frame of the base frame reinforcement structure according to claim 1, and a wire rod is attached to the corner shape retainer. Attached the end of. The wire may be made of metal or resin as long as it does not extend. Further, it is preferable that this wire rod has a length adjustable by a turnbuckle or the like.

[0007]

In the reinforcing structure of the base frame for moving a building according to the first aspect of the present invention, first, the opposite corners of the base frame are connected by wire rods. For example, if it is a rectangular room, two pairs of opposite corners are connected by a diagonal line. At this time, the rectangular room has a triangular truss structure and is not deformed even if an external force is applied. Similarly, in the case of a polygonal room, opposite corners are connected by diagonal lines to form a triangular truss structure. After this, the foundation frame is jacked up to separate it from the foundation and the building is moved. In the reinforcing structure of the base frame for moving a building according to claim 2, a corner shape retainer is attached to a corner of the base frame, and then an end of a wire is attached to the corner shape retainer to connect the corners. Form a truss structure with the base frame.
Then, the upper surface of the jack is applied to the lower surface of the corner shape retainer and lifted by a desired amount.

The present invention will be described below in detail with reference to the drawings showing the embodiments. (Embodiment 1) FIG. 1 is a plan view of a house according to an embodiment 1 in which a foundation frame is reinforced when moving a building according to the present invention, and FIG.
4 is a sectional view taken along line AA of FIG. 3, and FIG. 3 is a sectional view taken along line BB of FIG.
FIG. 4 is a perspective view of a corner shape retainer. Example 1 is an example of a work for vertically raising a house that is inclined in one direction and has only one space. 1 to 3, a base frame 1 for supporting a house is composed of base trees 11, 12, 13 and 14, which are fixed to a concrete base 2 with anchor bolts 21 ... 21 and are corners of the base frame 1. Pillars 3 ... As shown in FIG. 4, the corner shape retainer 4 is formed by processing a channel steel material into an L shape to reinforce the joint surface, and forming holes 41 on the top and bottom surfaces and a plurality of holes 42 at predetermined side surfaces. is there. Further, a turnbuckle is provided near the center, and hooks for passing through the holes 41 of the corner shape retainer 4 are formed at both ends of the steel wire 5 having a variable length. Further, 6 is a long channel steel material for reinforcing the foundation wood, and holes are formed at ten or more places on the side surfaces to be screwed to the side surfaces of the foundation woods 12 and 13. Inside the channel steel material 6, the corner shape retainer 4 is fitted as shown in FIG. Further, 7 is a jack, 8 is a pedestal put under the jack 7, and C is the ground. In addition, in FIG. 1, the foundation 2 on the left side of the house that supports the foundation 11 due to uneven settlement
However, it is assumed that the house sinks on the ground C and the house is tilted.

Next, a method for providing a reinforcing structure to the base frame of a tilted house and then raising the house vertically will be described.
Work is done either by removing the floorboards of the house or by going under the floor. First, the channel steel material 6 is put along the base woods 12 and 13, and fixed by screws. Channel steel 6
It is not necessary when the vertical load applied to the central portions of the base trees 12 and 13 is small. After that, the corner shape retainer 4 is screwed to the inside of the four corner portions of the base frame 1 using the holes 42. Then, the hooks at the ends of the wire rods 5 and 5 are stretched diagonally to form the truss structure by hooking the hooks at the ends of the corner shape retainers 4 at the four corners to the holes 41 on the upper surface or the lower surface, and the two wire rods 5・ Alternately adjust the tightening force of 5 with a turnbuckle. Next, the jacks 7 and 7 are arranged below the corner shape retainers 4 and 4 at both ends of the base tree 11 on the left side which is lowered from the horizontal position. The jack 7 is placed on the pedestal 8 so as not to get caught in the ground C. Then, the pushing-up surface 7a of each jack 7 is applied to the lower surface position of the corner shape keeping tool 4 shown in FIG. 2 and 3 show this state.

Next, all the anchor bolts 2 of the base frame 1
After removing 21 ... 21, while pushing the balance between the two jacks 4.4, push up the corner shape retainers 4.4.
Lift the foundations 11, 12 and 13 from the foundation 2. In this way, when the base frame 1 becomes horizontal,
A new foundation is provided below 12 and 13, and the upper surface of the foundation is made horizontal. The foundation frame 1 is fixed again to this foundation to erect the house and repair the damage to the interior and exterior.

Set up two corner shape retainers and base 1
When it is difficult to lift 1, the short channel steel material 40 is screwed to the middle portion of the base material 11 as shown in FIG. 1, and the third jack is set here, and the base material 11 is attached.
You may assist in raising the rice cake. Of course, instead of the short channel steel 40, a long one such as the channel steel 6 may be set and used. Moreover, the upper surface of the concrete base 2 is cut off to make a gap between the base 2 and the base wood 11, and a thick steel plate is inserted therein, and the parts protruding to the inside and outside of the base 2 are lifted with two jacks in a well-balanced manner. May be. This steel plate need not be fixed to the base wood 11. Furthermore, if the three corners of the house are lowered, it goes without saying that jacks should be set on the three corners and lifted in a well-balanced manner. Furthermore, if the wall surface is reinforced with two or more wire rods to form a truss structure, there is no risk of damage even if an unreasonable force is applied to the wall.

(Embodiment 2) The reinforcement structure of the base frame during the movement of the building of the embodiment 2 is used for the transfer work of the general house 9 having a plurality of rooms shown in the plan view of FIG. 5 and the perspective view of FIG. It is also applied at the occasion. As shown in FIG. 5, the house 9 can use the corner shape retainers 4 ... 4 and the wires 51, 52, 53, 54 to reinforce the base frame 10 for each room and jack up main columns. To do so. Further, depending on the size of the room, a channel steel material 61 is attached by screwing to the side surface of the base material 61 to reinforce it so that the base tree does not bend even if an unreasonable vertical load is applied during jacking up. At this time, not only is the tension of the two wire rods adjusted equally for each room, but also the wire rods 51, 52, 53, 54 of the entire house 9 are set so that an unnecessary force is not applied to a part of the base frame 10. You need to adjust the tension. In this way, the entire base frame 10 is integrated so that the base frame 10 does not deform even when it is hung. It should be noted that, in the house 9, after all the pillars have been once jacked up and the anchor bolts of the foundation have been removed from the foundation wood forming the foundation frame 10, the whole is lifted by a crane and transferred, and installed on another foundation. Therefore, as shown in FIG. 6, the steel wire rods 55, ... Are assembled and reinforced in the truss structure on all the walls of the building.

It should be noted that the corner shape retainer and the wire may be attached as they are without being removed even after the above-mentioned transfer work. At that time, we will always reinforce the structure of the house.
Further, the corner shape retainer and the channel steel material may be formed by angle steel material.
