Description

Technical Field

[0001] The present invention relates to a differential settlement correction machine for returning a building inclined due to ground settlement or the like to a horizontal state.

Background Art

[0002] Conventionally, when a building is inclined due to ground settlement or the like, there is an underpinning method as a construction method for returning the building to its original horizontal state.

[0003] The underpinning method is a method in which holes are dug under the foundation of a building, and a plurality of short steel pipes are repeatedly pressed in and connected until they reach a hard support layer, and after the steel pipe piles reach the support layer, a hydraulic jack is attached to the head portion of the steel pipe pile, and the foundation is lifted with the hydraulic jack to return the building to its original horizontal state, and a spacer or the like is installed at the head portion of the steel pipe pile for backfilling. However, in order to lift the foundation, a plurality of steel pipe piles must be installed directly under the foundation, and the steel pipe piles must be pressed into the ground support layer. Even in the case of a general wooden two-story house, a construction period of about one month is required. In addition, there are many problems in terms of cost and safety.

[0004] Furthermore, even when the building is returned to its original horizontal state in this way, there is a problem that the building settles differentially again over time.

[0018] Figure 2 shows the basic gripping tool 7 described in Figure 1 in a perspective view, and Figure 3 shows the basic gripping tool 7 shown in Figure 2 in an exploded view. The basic gripping tool 7 is formed from a channel steel with a thickness of 6 mm, a web width of 125 mm, a flange width of 65 mm, and a length of approximately 500 mm.

Further, on the upper surface of the flat pedestal steel plate 30, a rasp - shaped steel plate 13, formed from a rasp - shaped steel plate, is welded to prevent the basic concrete 3 and the flat pedestal steel plate 30 from sliding when the hydraulic jack 6 is operated, as described in Figure 1. To firmly fix the basic gripping tool 7 to the basic concrete 3, a plurality of anchor bolt holes 28 are drilled in the web 16 of the anchor bolt mounting member 12, and a plurality of anchor bolts 21 are inserted into the anchor bolt holes 28 and driven into the basic concrete 3 to fix the basic gripping tool 7 to the basic concrete 3. Note that the anchor bolts 21 used are preferably chemical anchor bolts to increase strength. In the present invention, a cut - off bolt with an M16 size and a length of 170 mm, a chemical anchor (resin capsule), and an M16 nut are used.

[0019] FIG. 4 shows a member 45 for lifting a foundation gripping tool for lifting the foundation concrete 3 when attached to the foundation gripping tool 7 described in FIGS. 1 and 2. The member 45 for lifting the foundation gripping tool is composed of two parallel reinforcing H-shaped steels (A) 46 made of H-shaped steel with a vertical dimension of 100 mm, a horizontal dimension of 100 mm, a web thickness of 6 mm, a flange thickness of 8 mm, and a length of 1100 mm, and a reinforcing H-shaped steel (B) 47. A plurality of holes 49, 50 and holes 55, 56 are formed in one flange (A) 54 and flange (B) 57 of the reinforcing H-shaped steel (B) 47. Further, in order to fix the flanges (C) 64 and (D) 65 of the two reinforcing H-shaped steels (A) 46 and the reinforcing H-shaped steel (B) 47 in parallel, both ends of two reinforcing steel plates (A) 60 and (B) 63 formed of flat steel plates with a thickness of 12 mm, a vertical dimension of about 150 mm, and a horizontal dimension of about 340 mm are welded and joined to the lower ends and generally two locations at the upper and lower centers of the flanges (C) 64 and (D) 65 so as to be flush. In this way, two reinforcing steel plates (A) 60 and (B) 63 welded and joined to the flanges (C) 64 and (D) 65 and the flanges (C) 64 and (D) 65 are welded and joined with two receiving members (A) 52 and (B) 53 having a thickness of 12 mm, a height of about 50 mm, and a length of about 540 mm. Further, at the left and right central portions of the receiving members (A) 52 and (B) 53, detachment prevention fittings (A) 59 and (B) 62 shown in FIG. 6 are welded and joined. Further, a state in which a hydraulic jack installation member 48 is fixed to a plurality of holes 49, 50 and holes 55, 56 formed in one flange (A) 54 and flange (B) 57 of the reinforcing H-shaped steel (A) 46 and the reinforcing H-shaped steel (B) 47 with bolts and nuts is shown.

[0020] FIG. 5 is a perspective view showing a state in which the two reinforcing H-shaped steels (A) 46 and the reinforcing H-shaped steel (B) 47 and the hydraulic jack installation member 48 described in FIG. 4 are separated. The reason for configuring the hydraulic jack installation member 48 to be vertically movable with respect to the two reinforcing H-shaped steels (A) 46 and the reinforcing H-shaped steel (B) 47 with a plurality of bolts 69, 68 and nuts 51 and nuts (not shown) is that due to the height difference of the land caused by sloping ground or the like, even in a building constructed on the same site, the ground surface may not be horizontal but inclined with respect to the position of the foundation concrete.

[0021] Figure 6 is a perspective view showing a state of viewing the two reinforcing H-shaped steels (A) 46 and the reinforcing H-shaped steel (B) 47 described in FIG. 4 and the member 48 for installing a hydraulic jack from the opposite side. At the lower ends of the flange (C) 64 of the reinforcing H-shaped steel (A) 46 and the flange (D) 65 of the reinforcing H-shaped steel (B) 47, a receiving member (B) 53 having a thickness of 12 mm, a length of approximately 50 mm, and a width of approximately 540 mm is welded and joined so that the lower ends of the flange (C) 64, the flange (D) 65, and the receiving member (B) 53 are flush. At a position approximately 500 mm from the lower ends of the flange (C) 64 of the reinforcing H-shaped steel (A) 46 and the flange (D) 65 of the reinforcing H-shaped steel (B) 47, the lower end of a receiving member (A) 52 having a thickness of 12 mm, a length of approximately 50 mm, and a width of approximately 540 mm is welded and joined. In the left and right central portions of the receiving member (A) 52 and the receiving member (B) 53 thus welded and joined, approximately 50 mm of the upper half of a flat steel plate having a thickness of 6 mm, a length of approximately 100 mm, and a width of approximately 100 mm is bent in a trapezoidal shape at an angle of approximately 30 degrees, and a state in which the lower half of approximately 50 mm of the detachment prevention fitting (A) 59 and the detachment prevention fitting (B) 62 is welded and joined is shown in a perspective view.

[0022] Furthermore, in FIG. 6, in order to lift the foundation gripping device 7 installed below the foundation concrete 3 described in FIG. 1, to clearly explain how the load receiving steel plate 25 and the fall prevention steel plate 18 of the foundation gripping device 7 described in FIG. 2 are coupled to the receiving member (A) 52, the receiving member (B) 53, the detachment prevention fitting (A) 59, and the detachment prevention fitting (B) 62, a state in which the load receiving steel plate 25 (shown by a dotted line) and the fall prevention steel plate 18 (shown by a dotted line) described in FIGS. 2 and 3 are coupled to the upper part (A) 76 of the receiving member (A) 52 and the upper part (B) 77 of the receiving member (B) 53 is shown. Note that the upper half portions of the detachment prevention fitting (A) 59 and the detachment prevention fitting (B) 62 are bent and formed at an angle of approximately 30 degrees in the direction of the foundation gripping device 7 described in FIG. 1 so that they can be easily coupled to the load receiving steel plate 25 and the fall prevention steel plate 18.

[0023] Figure 7a of Fig. 7 shows the member 48 for installing the hydraulic jack described in Fig. 5 in a perspective view. Fig. 7b shows the member 48 for installing the hydraulic jack described in Fig. 7a in an exploded view. The member 48 for installing the hydraulic jack is formed by bending both longitudinal sides of a flat steel plate with a thickness of 6 mm, a length of approximately 310 mm, and a width of approximately 540 mm at right angles in the same direction by approximately 30 mm into a U-shaped to form a U-shaped reinforcing mounting steel plate 80. A plurality of holes 49, 50 formed in the flanges (A) 54 and flanges (B) 57 described in Figs. 4 and 5, and a plurality of holes 71, 82 and holes 83, 84 are formed at positions corresponding to the holes 55, 56 on the left and right sides of the web 81 of the U-shaped reinforcing mounting steel plate 80. Further, for welding and joining approximately on the left and right of the web 81, two trapezoidal reinforcing steel plates (A) 72 and trapezoidal reinforcing steel plates (D) 75 with a thickness of 12 mm, a lower base of approximately 250 mm, an upper base of approximately 40 mm, and a height of approximately 125 mm are formed into a generally trapezoidal shape. Further, two trapezoidal reinforcing steel plates (B) 73 and trapezoidal reinforcing steel plates (C) 74 with a thickness of 12 mm, a lower base of approximately 250 mm, an upper base of approximately 80 mm, and a height of approximately 155 mm are formed into a generally trapezoidal shape for welding and joining between the trapezoidal reinforcing steel plates (A) 72 and trapezoidal reinforcing steel plates (D) 75. Further, a reinforcing triangular steel plate (A) 89 formed by bending a flat steel plate with a thickness of 6 mm, a width of approximately 140 mm, and a length of 330 mm into a Z-shaped for welding and joining at the roots of the bent both sides of the web 81 sandwiched between the trapezoidal reinforcing steel plate (A) 72 and the trapezoidal reinforcing steel plate (B) 73. Similarly, a reinforcing triangular steel plate (B) 91 formed by bending a flat steel plate with a thickness of 6 mm, a width of approximately 140 mm, and a length of 330 mm into a Z-shaped for welding and joining at the roots of the bent both sides of the web 81 sandwiched between the trapezoidal reinforcing steel plate (C) 74 and the trapezoidal reinforcing steel plate (D) 75. Further, a top plate 88 for the hydraulic jack formed by a flat steel plate with a thickness of 12 mm, a length of approximately 155 mm, and a width of approximately 130 mm is welded and joined so as to be parallel to the ground surface between the trapezoidal reinforcing steel plates (B) 73 and the trapezoidal reinforcing steel plates (C) 74. Further, two triangular reinforcing plates (A) 86 and triangular reinforcing plates (B) 87 formed by a flat steel plate with a thickness of 12 mm, a height of approximately 136 mm, and a width of approximately 142 mm and formed into a generally right-angled triangular shape are welded and joined to the upper surface of the top plate 88 for the hydraulic jack for reinforcement. Further, a top plate reinforcing steel plate 90 formed by a flat steel plate with a thickness of 12 mm, a width of approximately 130 mm, and a length of approximately 170 mm is welded and joined to the hypotenuses of the two triangular reinforcing plates (A) 86 and triangular reinforcing plates (B) 87 for reinforcement, and is shown in a perspective view.

[0024] Figs. 8 and 9 illustrate the H-shaped steel sheet 5 for earth pressure dispersion for supporting the hydraulic jack 6 described in Fig. 1. The hydraulic jack 6 described in Fig. 1 is a product with a lifting capacity of 30 tons. When the hydraulic jack 6 is operated, in order to reduce the sinking of the hydraulic jack 6 into the ground and operate it in a stable state, on both sides in the longitudinal direction of a flat steel plate with a thickness of 6 mm, a length of approximately 260 mm, and a width of approximately 300 mm at the lower part of the hydraulic jack 6, it is bent at a right angle of approximately 30 mm in a U-shape to form the bent portion (A) 137 and the bent portion (B) 143. The U-shaped steel plate 102 for the hydraulic jack is arranged. Further, the flanges of the H-shaped steel sheet 5 for earth pressure dispersion formed of an H-shaped steel with a length of 200 mm, a width of 200 mm, a web thickness of 8 mm, and a flange thickness of 12 mm are arranged vertically below the U-shaped steel plate 102 for the hydraulic jack. A plurality of holes are formed in the bent portion (A) 137 and the bent portion (B) 143 of the U-shaped steel plate 102 for the hydraulic jack. In order to assemble the U-shaped steel plate 102 for the hydraulic jack formed in this way to the H-shaped steel sheet 5 for earth pressure dispersion, as shown in the exploded view of Fig. 10, a plurality of holes 135 are formed in the bent portion (A) 137 of the U-shaped steel plate 102 for the hydraulic jack, and further, a plurality of holes 136 are also formed in the bent portion (B) 143. Further, the bottom plate (A) 132, the reinforcing plate (A) 130, and the diagonal reinforcing plate (A) 127 shown in Fig. 10 are welded and joined to form a generally L-shaped anti-disengagement member (A) 131. The bottom plate (A) 132 of the anti-disengagement member (A) 131 is inserted under the lower flange 105 of the H-shaped steel sheet 5 for earth pressure dispersion, and the bent portion (A) 137 and the anti-disengagement member (A) 131 are fixed with a plurality of bolts 134 and nuts 128. Similarly, the bent portion (B) 143 of the U-shaped steel plate 102 for the hydraulic jack and the anti-disengagement member (B) 103 are fixed with a plurality of bolts 133 and nuts 141. A perspective view shows a state in which the H-shaped steel sheet 5 for earth pressure dispersion is sandwiched and fixed in a sandwich shape by the U-shaped steel plate 102 for the hydraulic jack, the anti-disengagement member (B) 103, and the anti-disengagement member (A) 131.Incidentally, the reason for sandwiching the soil pressure dispersion H-shaped steel 5 between the U-shaped hydraulic jack steel plate 102, the detachment prevention member (B) 103, and the detachment prevention member (A) 131 in this manner is to increase the installation surface on the ground surface, thereby stabilizing the U-shaped hydraulic jack steel plate 102 placed on the upper surface of the upper flange 104 of the soil pressure dispersion H-shaped steel 5. By configuring the vertical and horizontal dimensions of the bottom plate (A) 132 and the bottom plate (B) 138 that constitute the detachment prevention member (A) 131 and the detachment prevention member (B) 103 to be wider than the width (200 mm) of the flange of the soil pressure dispersion H-shaped steel 5, the force of the hydraulic jack 6 applied to the soil pressure dispersion H-shaped steel 5 is widely dispersed and received across the entire ground surface.

[0025] Figure 9 shows a state where a plurality of soil pressure dispersion L-shaped steel plates 110, each with a thickness of 6 mm, a length of approximately 300 mm, and a width of approximately 600 mm, and with one tip at the lateral side bent at a right angle by approximately 50 mm, are spread out at the lower part of the soil pressure dispersion H-shaped steel 5. This is to disperse the pressing force of the hydraulic jack 6 against the ground surface 4 described in FIG. 1 and prevent the hydraulic jack mounting member 99 from sinking into the ground. By overlapping and continuously spreading out the ends of the plurality of soil pressure dispersion L-shaped steel plates 110 at the lower part of the soil pressure dispersion H-shaped steel 5 in this way, it becomes possible to prevent the hydraulic jack 6 from sinking into the ground by dispersing the force of the hydraulic jack 6 against the ground.

[0026] Figure 10 shows an exploded view of the hydraulic jack mounting member 99 described in FIG. 8 in an exploded state.

[0027] Figure 11 is a perspective view showing the positional relationship among the foundation gripping device 7 described in FIG. 2, the foundation gripping device lifting member 45 described in FIG. 4, and the hydraulic jack mounting member 99 described in FIG. 8 in an easy-to-understand manner.

[0028] Figure 12 is a perspective view showing a state where the foundation gripping device lifting member 45 and the hydraulic jack mounting member 99 are attached to the foundation gripping device 7 shown in FIG. 11.

[0029] Based on the above embodiments, the differential settlement correction machine according to the present invention has been described in detail. However, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the invention, and of course, it belongs to the technical scope of the present invention.
