BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for reinforcing a base frame when an inclined building is raised or an existing building is lifted and transported as it is.

[0002]

2. Description of the Related Art As an apparatus used to raise a building tilted from a foundation due to liquefaction phenomenon or landslide caused by an earthquake, for example, Japanese Patent Publication No. Sho 52-2502 proposed by the present applicant has been proposed.
There is a lifting device described in Japanese Patent Publication No. In brief, this device is such that a channel-type attachment plate is fixed to the side surface of each pillar, and the pillars are pushed up by jacks juxtaposed to each pillar while maintaining a good balance between the pillars.

As a method of transporting a building, there is, for example, a method described in Japanese Patent Publication No. 5-29744 proposed by the present applicant. In this method, reinforcing steel is framed along the outer periphery of the lower part of the building, the steel is attached to the truss structure on the frame of the outer peripheral wall of the building, the building is lifted off the ground by means of lifting and lowering, and the transportation means is positioned underneath. Then, the building is lowered by the lifting means and placed on the transportation means, and the building is transferred by the transportation means while ensuring the internal stability of the building.

[0004]

However, when the whole or a part of the building is lifted or transported by the transportation means, if a force is applied to the building such that the columns come close to or separate from each other, the base frame is not provided. May be deformed or destroyed, at which time the building will be unusable.

[0005] The present invention has been proposed in view of the above problems, and when the base frame is lifted to correct the inclination of the building or to transport the building, the base frame is deformed. It is an object of the present invention to provide a structure for reinforcing a base frame at the time of moving a building, which has no work and improves workability.

[0006]

In order to solve the above-mentioned problems, the reinforcing structure of the foundation frame at the time of moving the building according to claim 1 is applied when the foundation frame of the building is separated from the foundation and pushed up by a jack and moved. It is a reinforcement structure of the base frame when moving the building, and the channel steel material is attached to the inner surface of the base frame.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings showing embodiments. First Embodiment FIG. 1 is a plan view of a house according to a first embodiment of the present invention in which a foundation frame is reinforced when a building is moved according to the present invention, FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, and FIG. 1 is a sectional view taken along the line BB of FIG. 1, and FIG. 4 is a perspective view of the corner retainer. The first embodiment is an example of an operation in which a house with only one room inclined in one direction is vertically raised. In FIG. 1 to FIG. 3, a base frame 1 for supporting a house includes
13 and 14, these are concrete foundations 2
Is fixed with anchor bolts 21 ‥‥‥ 21 to the base frame 1
A pillar 3 ‥‥ 3 is erected on the corner. 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 joining surface, and has a hole 41 on the top and bottom surfaces and a plurality of holes 42 on predetermined side surfaces. is there. In addition, a turnbuckle is provided near the center, and a steel wire rod 5 having a variable length is provided with a hole 4 of a corner retainer 4 at both ends.
The hook for passing through 1 is formed. Reference numeral 6 denotes a long channel steel material for reinforcing the foundation.
Holes are drilled in more than a dozen places on the side for screwing to the side of 3. The inside of the channel steel 6 is shown in FIG.
The corner shape retainer 4 fits in as shown. Reference numeral 7 denotes a jack, 8 denotes a pedestal placed under the jack 7, and C denotes the ground. In FIG. 1, it is assumed that the foundation 2 on the left side of the house supporting the foundation 11 sinks into the ground C and the house is inclined due to uneven settlement.

Next, a description will be given of a method of providing a reinforcing structure to a base frame of an inclined house, and thereafter raising the house vertically.
Work can be done by removing the floorboard of the house or by going under the floor. First, the channel steel 6 is attached to the foundations 12 and 13 and fixed by screws. Channel steel 6
This is not necessary when the vertical load applied to the central portions of the foundations 12 and 13 is small. After that, the corner retainer 4 is screwed to the inside of the four corners of the base frame 1 using the holes 42 ‥‥‥ 42. Subsequently, the hooks at the ends of the wires 5.5 are hooked to the holes 41 on the upper surface or the lower surface of the four corner holders 4 to stretch the two wires 5.5 diagonally to form a truss structure.・ Adjust the tightening force of 5 alternately with a turnbuckle to make it even. Next, the jacks 7.7 are arranged under the corner retainers 4 at both ends of the left base 11 which are lowered from the horizontal position. The jack 7 is placed on the pedestal 8 so as not to sink into the ground C. Then, the push-up surfaces 7a of the respective jacks 7 are brought into contact with the lower surface position of the corner retainer 4 shown in FIG. 2 and 3 show this state.

Next, all anchor bolts 2 of the base frame 1

A new foundation is provided below 12 and 13, and the upper surface of the foundation is leveled. The base frame 1 is fixed to this foundation again, and the house is erected, and the damage of the interior and exterior is repaired.

[0011] Two corner shape holders are set and the base 1
When it is difficult to lift the base material 11, as shown in FIG. 1, a short channel steel material 40 is screwed to the middle part of the base material 11, and a third jack is set here.
You may assist in hoisting. Of course, instead of the short channel steel material 40, a long material such as the channel steel material 6 may be set and used. In addition, a gap is formed between the foundation 2 and the concrete foundation 2 without the upper surface, a thick steel plate is inserted into the gap, and the inner and outer parts of the foundation 2 are lifted up with two jacks in a well-balanced manner. You may. This steel plate does not need to be fixed to the base 11. Furthermore, if the three corners of the house are lowered, it goes without saying that jacks are set in the three corners and lifted in a well-balanced manner. Furthermore, if the wall surface is reinforced with two or more wires to form a truss structure, there is no fear that the wall will be broken even if an excessive force is applied.

(Embodiment 2) The reinforcement structure of the base frame when moving the building according to Embodiment 2 is used for the transfer operation of a 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 time. As shown in FIG. 5, the housing 9 uses the corner shape retainers 4... 4 and the wire rods 51, 52, 53, and 54, and the base frame 1 for each room.
Reinforce the 0 to allow key pillars to be jacked up. Further, depending on the size of the room, a channel steel material 61 is screwed on the side surface to reinforce the base material so that the base material does not bend even if an excessive vertical load is applied at the time of jacking up. At this time, not only the tension of the two wires for each room is adjusted evenly, but also the wires 51 of the entire house 9 so that an unreasonable force is not applied to a part of the base frame 10.
It is necessary to adjust the tension of 52, 53, 54. By doing so, the entire base frame 10 is integrated, so that the base frame 10 is not deformed even when it is suspended. In addition, after all the pillars are once lifted by the jack and the anchor bolts of the foundation are pulled out of the foundation forming the foundation frame 10, the house 9 is entirely lifted and transferred by a crane, and is installed on another foundation. As shown in FIG. 6, steel wires 55, 56,...
Reinforced with truss structure.

[0013] After the above-mentioned transfer work, the corner shape retainer and the wire may be attached without being removed. At that time, the structure of the house will always be reinforced.
Further, the corner retainer and the channel steel material may be formed of an angle steel material.

[0014]

According to the reinforcing structure of the base frame when the building is moved according to the first aspect, the opposite corners of the base frame are connected by the wire, so that the inclination of the building is corrected or the building is transferred. Therefore, even when the base frame is lifted, the base frame is not deformed and the building is not distorted. In addition, according to the reinforcing structure of the base frame at the time of moving the building according to claim 2, since the corner of the base frame is maintained in its shape by attaching the corner shape retainer, the corner is maintained even if an excessive force is applied. Is not deformed. In addition, since the corner shape retainer is attached, the jack can be easily applied and workability is improved.
