  In this embodiment, the foundation 11 of the existing building 10 is a solid foundation in which a foundation slab 11b is arranged inside the outer peripheral rising portion 11a as shown in FIG. In addition, the foundation ground 12 directly below the foundation 11 is a ground of the surface layer portion that firmly supports the load from the building 10 that is loaded via the foundation 11 and that is dispersed and transmitted to the lower ground. In order to support the load from 10 efficiently, the ground crushed stone is spread and ground improvement etc. are suitably given.

  Moreover, in this embodiment, the raising / lowering support box 15 installed along the lower surface of the foundation 11 is the same as the upper support part 15b provided with a U-shaped cross section as shown in FIGS. The upper support plate 15a is raised with respect to the lower support plate 15c by superimposing the lower support portion 15d having a U-shaped cross-sectional shape on the upper and lower sides with the U-shaped open side facing each other. In the absence (see FIG. 5A), for example, it has a horizontally long and substantially rectangular hollow cross-sectional shape with a width of about 100 to 300 mm and a height of about 100 to 300 mm.

  The upper support portion 15b and the lower support portion 15d constituting the elevating support box 15 are preferably formed by bending one iron plate using an iron plate having a thickness of, for example, about 2 to 20 mm, or three iron plates. Can be easily formed so as to have a U-shaped cross-sectional shape of a desired size by, for example, integrating them by welding. In this embodiment, the elevating support box 15 is formed to have an axial length of, for example, about 500 to 1000 mm.

  Further, in the present embodiment, in each row where the lifting support boxes 15 are arranged in series, the hollow box 18 (see FIGS. 1 and 4C) provided between the adjacent lifting support boxes 15. Reference) is a box made of concrete or metal, for example, and is preferably formed as a concrete cylindrical body with both ends being open surfaces. The hollow box 18 is provided with a flat, oblong, substantially rectangular, hollow cross-sectional shape that is substantially the same as the lifting support box 15, for example, having a width of about 150 to 350 mm and a height of about 100 to 300 mm. It is formed so that it may be longer than the lifting support box 12, for example, about 1000 to 2000 mm.

  In each row, the hollow box 18 is disposed between adjacent lifting support boxes 15 to form a communication path that connects the connected lifting support boxes 15 to each other. Further, when the elevating support box 12 and the hollow box 16 are connected along the lower surface of the foundation 11 of the building by the propulsion method and are installed in a row, the hollow box 18 is placed at the end of the main push side. Also, the opening surface at the end thereof is opened as the introduction opening 16 in the foundation ground 12 in the outer peripheral portion of the foundation 11. Thus, the lift-up means 14 can be easily introduced from the introduction opening 16 into the hollow interior of each row of the lifting support boxes 15 through the communication path by the hollow box 18 from the outside of the foundation 11. It becomes possible to arrange.

  In the present embodiment, a plurality of lifting support boxes 15 in which lift-up means 14 are arranged along the lower surface of the foundation 11 communicate with the introduction opening 16 that opens to the foundation ground 12 in the outer peripheral portion of the foundation 11. The step of installing in a possible state can be easily performed by propulsion, preferably by propelling while raising and lowering support boxes 15 and hollow boxes 18 are alternately arranged.

  In order to install the lifting support box 15 and the hollow box 18 in a row along the lower surface of the foundation 11 of the building 10 by the propulsion method, for example, as shown in FIG. 2 and FIG. The foundation ground 12 adjacent to one of the long sides of the building foundation 11 is dug down to form a propulsion work yard 30 that is one level lower than the surrounding ground surface. Further, as shown in FIG. 4A, the bearing wall 31, the propulsion base 32, the propulsion jack 33, and the like are installed in the propulsion work yard 30 formed.

  Thereafter, as shown in FIG. 4 (b), the elevating support box 15 and the hollow box 18 are alternately connected in the axial direction via a known joint mechanism so that these hollow interiors communicate with each other. For example, while cutting the ground surface of the tip face with a water jet, the propulsion jack 33 sequentially pushes from the propulsion base 32 toward the base ground 12 immediately below the foundation 11 of the building 10.

  Here, the propulsion method using a water jet is a well-known method for propelling and installing a hollow box such as a square steel pipe in the ground, and is a pressure water pressure equipped with a jet water injection nozzle at the tip. In the state where the pipe is inserted inside the box, jet water is sprayed from the spray nozzle toward the face of the face of the box, thereby cutting the earth and sand on the face with the jet water. The box is pushed to the ground with a propulsion jack while being sequentially added to the main pushing side through the hollow interior of the box together with the mud water from the jet water, and the box is pushed to a predetermined depth. This is a known construction method that can be embedded.

  Further, in the present embodiment, the face hollow surface 18 ′ preferably provided with a blade edge is attached to the tip portion in the propulsion direction, and the lifting support box 15 and the hollow box 18 are propelled to move the face. It becomes possible to cut the earth and sand more easily.

  In the present embodiment, when the lifting support box 15 and the hollow box 18 are propelled toward the foundation ground 12 while cutting the soil on the face, the upward propulsive force is applied to the tip portion in the propulsion direction. For example, the lifting / lowering support box 15 and the hollow box 18 are made to follow the lower surface of the foundation 11 without being separated from the lower surface of the foundation 11 by, for example, devising and forming the shape of the blade edge. In this state, it is possible to easily and continuously arrange the foundation ground 12 directly below the foundation 11.

  And in this embodiment, by the above-mentioned propulsion method, the lifting support box 15 and the hollow box 18 are arranged in an alternating manner along the lower surface of the foundation 11 as shown in FIG. It will be installed in three rows at the central part and both side parts of the foundation 11 having a planar shape. Further, the lifting support box 15 and the hollow box 18 have a tip end portion in the propulsion direction from one long side portion where the propulsion work yard 30 is provided in the foundation 11 of the building 10 having a substantially horizontally long rectangular planar shape. It extends to a position close to the long side portion of the building 10 and is installed on the foundation ground 12 immediately below the foundation 11 of the building 10. Accordingly, the plurality of lifting support boxes 15 are distributed and distributed in a well-balanced manner over the entire foundation ground 12 immediately below the foundation 11 of the building 10 including the inner region of the outer periphery of the foundation 11 of the building 10. Will be. In each row, the opening surface of the end of the hollow box 18 arranged at the base end on the side of the propulsion work yard 30 serves as the introduction opening 18 in the propulsion work yard 30. Will open.

  When the lifting support box 15 and the hollow box 18 are continuously arranged in a plurality of rows on the foundation ground 12 directly below the foundation 11 by the propulsion method, as shown in FIG. The propulsion base 32, the propulsion jack 33, etc. are removed.

  In the present embodiment, in the step of disposing the lift-up means 14 in the hollow interior of the elevating support box 15, the lift-up means 14 is preferably an inflatable bag that inflates and deforms when a fluid pressure is applied to the inside from a flat state. The body is installed in the hollow interior of each lifting support box 15 through the introduction opening 16 by work from the outside of the foundation 11.

  The operation of installing each of the expansion bag bodies 14 in the hollow interior of the lifting support box 15 is performed in a state in which one end of the pressure feeding hose 34 (see FIG. 4C) is connected to the injection port of the expansion bag body 14. As work from the outside, for example, work from the propulsion work yard 30 can be easily performed. That is, for example, using an operation rod having a function of pushing in and pulling out the expansion bag body 14, the introduction opening 16 opened in the propulsion work yard 30, the communication path by the hollow box 18, and the lifting support located in the middle part By introducing the expansion bag body 14 by pushing it through the hollow interior of the box 15, it is possible to easily perform the operation of installing the expansion bag body 14 inside the selected lifting support box 15. it can.

  Here, as the inflatable bag body which is the lift-up means 14, various well-known bag bodies having a function of inflating and deforming when a fluid pressure is applied to the inside from a flat folded state can be used. . In the present embodiment, the inflatable bag body 14 uses a sheet material similar to that used for fire fighting hoses, for example, and breaks even when a high water pressure of about 0.2 to 0.3 MPa is applied to the inside. It can be easily formed in a state where there is no such thing. The inflatable bag body 14 is provided with an inlet, for example, at one end thereof, and when the inflated bag body is inflated by injecting, for example, pressurized water as a pressurized fluid into the inside from the inlet, the height is, for example, about 150 to 500 mm. Thus, it is formed so that it can expand and deform.

  As a result, the inflatable bag body 14 expands inside the elevating support box 15 to raise the upper surface support plate 15a of the upper support portion 15b relative to the lower surface support plate 15c of the lower support portion 15d. Can be pushed up (lifted up) together with the building 10 with a lift-up amount in the range of about 50 to 500 mm, for example.

  In this embodiment, by operating the lift-up means 14, the foundation 11 is lifted up together with the building 10, and in the process of forming the spacing portion S between the foundation 11 and the foundation ground 12 below the foundation 11, As shown in FIG. 4 (c), the other end of the pressure feeding hose 34 having one end connected to the inlet of the expansion bag body 14 installed in the hollow interior of the support box 15 is connected to the pressure water pressure feeding pump 35. Thus, the expansion bag body 14 is inflated by the fluid pressure of the pressure water by pumping the pressure water. As a result, as shown in FIGS. 3A and 3B and FIGS. 5A and 5B, the upper support plate 15a of the upper support portion 15b rises relative to the lower support plate 15c of the lower support portion 15d. By lifting the foundation 11 together with the building 10, an interval portion S having a height sufficient to install the rail member 13 and the traveling member 17 between the foundation 11 and the foundation ground 12 below the foundation 11, It can be easily formed.

  Moreover, the base 11 is controlled by collectively controlling, for example, the pressure or the pressure amount of the pressure water, which is pumped from the pressure water pump 35 through the pumping hose 34 to each of the inflatable bag bodies 14, by a control device. It is possible to lift the building 10 together with a more accurate and stable state.

  A plurality of rail members 13 are inserted into a spacing portion S formed between the foundation 11 whose one end is lifted up and the foundation ground 12 below the same, and the other end is moved to the existing building 10. As shown in FIG. 2, the process of extending to the position and laying on the ground surface of the foundation ground 12 is, for example, using H-shaped steel or I-shaped steel as the rail member 13 as in the conventional foundation co-moving method. For example, it can be easily performed while adding in the axial direction using, for example, welded joints or joint hardware.

  The foundation ground 12 between the current position and the movement position and the foundation ground 12 at the movement position are appropriately grounded so that the ground surface becomes a laying surface of the flat rail member 13. In order to stably support the load from the rail member 13, a basic crushed stone, a laid iron plate, or the like is appropriately laid. Furthermore, the base ground 12 at the movement position is provided with lift-up means used in the step of lifting the foundation 11 that has moved to the movement position together with the building 10. As the lift-up means used at the moving position, the lift-up means 14 used at the current position can be diverted and installed as will be described later.

  At the current position, the lift-up means 14 is operated to lower the upper surface pressure plate 15a of the plurality of lifting support boxes 15 so that the foundation 11 and the building 10 together with the traveling member 17 are interposed on the rail member 13. In the step of installing in the same manner as in the conventional foundation co-moving method, for example, it is pushed up by the lift-up means 14 by the work through the gap portion S formed between the foundation 11 and the foundation ground 12 below it. For example, the traveling member 17 including rollers, wheels, bearings, and the like can be supported between the foundation 11 and the rail member 13 laid in the gap portion S so that the foundation 11 can be stably supported. A plurality of bases 11 are installed in a distributed manner throughout the foundation 11. Thereafter, the upper pressure bearing plate 15a of the upper support portion 15b is lowered with respect to the lower pressure bearing plate 15c of the lower support portion 15d by draining the pressure water from the expansion bag body 14 as a lift-up means and causing shrinkage deformation. The foundation 11 is lowered together with the building 10.

  This makes it possible to install the base 11 on the rail member 13 with the traveling member 17 interposed in a stable state together with the building 10. Further, by controlling the drainage pressure and the drainage amount of the pressure water drained from each of the inflatable bag bodies 14 via the pressure feeding hose 34 by, for example, a control device, the foundation 11 and the building 10 can be more accurately controlled. It can be lowered and installed on the rail member 13 in a stable state.

  The process of moving the foundation 11 installed on the rail member 13 together with the building 10 to the moving position of the existing building 10 along the rail member 13 is the same as in the conventional foundation co-moving method. This can be done by pulling the existing building 10 into the moving position using a traction device. In this embodiment, when the foundation 11 is moved to the region between the current position and the moving position together with the building 10, the lift-up means 14 used at the current position is removed together with the lifting support box 15 and the hollow box 18. These are preferably used by being transferred together with the lift-up means 14 by installing them in a plurality of rows on the foundation ground 12 in the moving position as in the current position.

  In the present embodiment, the lift-up means 14 is diverted together with the elevating support box 15 and the hollow box 18 at the moving position so that the lifted foundation 11 is moved down together with the building 10 as described later. After the step of grounding on the foundation ground at the position, the lift-up means 14 is moved from the hollow inside of the lifting support box 15 through the communication path by the hollow box 18 by the work from the outside of the foundation 11 in the moving position. It can be taken out and easily collected.

  The step of lifting up the foundation 11 that has moved along the rail member 13 together with the building 10 at the moving position of the existing building 10 is preferably the current position installed at the moving position, as in the conventional foundation co-moving method. It can be easily performed by pushing up the foundation 11 together with the building 10 using the lift-up means diverted from.

  The step of removing the rail member 13 and the traveling member 17 from the space between the lifted foundation 11 and the foundation ground 12 below the lifted-up foundation 10 at the moving position of the existing building 10 is the same as the conventional foundation co-movement method. Similarly, the base member 11 is pushed up together with the building 10, and the traveling member 17 is interposed between the base member 11 and the rail member 13 by an operation through a gap formed between the base member 11 and the base ground 12 below the base member 11. And removing the rail member 13 from the space between the foundation 11 and the foundation ground 12 can be easily performed.

  In the moving position of the existing building 10, the step of bringing the lifted-up foundation 11 together with the existing building 10 into contact with the foundation ground 12 is, for example, lift-up as in the conventional foundation co-moving method. It can be easily performed by lowering the foundation 11 together with the building 10 until the foundation 11 is grounded on the foundation ground 12 by draining the pressure water from the expansion bag body 14 as a means and contracting and deforming it. it can.

  In the present embodiment, the work from the outside of the foundation 11 is further performed after the step of grounding the foundation 11 on the foundation ground 12 by lowering the lifted foundation 11 together with the building 10 at the moving position of the existing building 10. The step of taking out the lift-up means 14 from the hollow interior of the lifting support box 15 is included. That is, in the present embodiment, at the moving position of the existing building 10, the lifting support boxes 15 are preferably arranged in a row in a state of being alternately connected to the hollow box 18, similarly to the current position of the existing building 10. Since it is installed, each through the introduction opening opened to the foundation ground 12 of the outer peripheral part of the foundation 11, the communication path by the hollow box 18, and the hollow interior of the lifting support box 15 located in the middle part The lift-up means 14 can be easily taken out from the lifting support box 15.

  Further, at the moving position of the existing building 10, the lifting support box 15 and the hollow box 18 installed on the foundation ground 12 are preferably filled with a solidified material appropriately after the lift-up means 14 is taken out. In a filled state, it can be left on the foundation ground 12 as a semi-permanent structure.

  And according to the house construction method of this embodiment provided with the above-mentioned structure, the lift-up means 14 is easily installed also in the inner area | region rather than the outer peripheral part of the foundation 11, and the whole foundation 11 is put together with the existing building 10. In a balanced and stable state, it can be adjusted so that it can be lifted up while being supported from below, and the existing building 10 is installed along the rail member 13 laid continuously from the current position to the moving position. 11 can be moved smoothly to a moving position in a stable state.

  That is, according to the present embodiment, preferably, by the propulsion method, the elevating support boxes 15 are arranged in a row while interposing the hollow box 18, so that the foundation 11 can be placed at the current position of the existing building 10. A plurality of lifting support boxes 15 in which lift-up means 14 are arranged can be easily installed along the lower surface in a state where they can communicate with the introduction opening 16 opened in the foundation ground 12 in the outer peripheral portion of the foundation 11. In addition, the lift-up means 14 can be easily arranged in the hollow interior of the elevating support box 15 through the introduction opening 16 by the work from the outside of the foundation 11, so The lift-up means 14 can be installed at any position suitable for lifting the foundation 11 in a well-balanced manner, including the inner region. 1 of the whole, with existing stable with a building 10, it is possible to adjust so as to be lifted up while supported from below.

  Further, by lifting up the foundation 11 together with the building 10, a plurality of lift-up means 14 provide good balance on the rail member 13 laid on the space portion S formed between the foundation 11 and the foundation ground 12. Since it becomes possible to install the foundation 11 of the building by lowering the foundation 11 while maintaining the lifted state, along the rail member 13 continuously laid from the current position to the moving position, the existing foundation 11 can be installed. The building 10 can be moved smoothly together with the foundation 11 to the moving position in a stable state.

  Note that the present invention is not limited to the above embodiment, and various modifications can be made. For example, the lift-up means does not necessarily need to be an inflatable bag body that inflates and deforms from a flat state, but is disposed in an elevating support box installed in a state where it can communicate with an introduction opening that opens in the foundation ground of the outer peripheral portion of the foundation For example, a jack device using a hydraulic jack or the like having a possible size and shape may be used. In addition, the lifting support box does not necessarily need to be installed on the foundation ground along the lower surface of the foundation by the propulsion method, and can be communicated with the introduction opening that opens to the foundation ground at the outer periphery of the foundation by other methods. Can be installed. Further, it is not always necessary that both the upper support portion and the lower support portion constituting the lifting support box have a U-shaped cross section, and only one of them is a U-shaped cross section. It may have a shape.
