Description

[Technical field]

[0001] The present invention relates to an uneven settlement correction machine for restoring a building that has become tilted due to subsidence or the like to a horizontal position. [Background technology]

[0002] Conventionally, when a building tilts due to subsidence or the like, an underpinning method has been used to return the building to its original horizontal position.

[0003] The underpinning method involves digging a hole under the foundation of a building and driving in multiple short steel pipes by repeatedly pressing and connecting them until they reach a hard supporting layer. After the steel pipe piles reach the supporting layer, a hydraulic jack is attached to the head of the steel pipe pile and the foundation is raised using the hydraulic jack to return the building to its original horizontal state. Spacers or the like are then placed on the heads of the steel pipe piles and the piles are backfilled. However, in order to raise the foundation, multiple steel pipe piles must be installed directly under the foundation and then pressed into the supporting layer of the ground. Even for a typical two-story wooden house, this method takes about a month to complete, and there were also many problems in terms of cost and safety.

[0004] Furthermore, even if the building was returned to its original horizontal position in this way, there was still the problem that the building would sink unevenly again over time. Summary of the Invention [Problem to be solved by the invention]

[0005] This invention has been made in consideration of the above problems, and has as its object to provide an uneven settlement correction machine that takes into consideration the safety of workers, can return an unevenly settled building to its original state at low cost and in a short construction period, and can furthermore, if the building tilts again due to an earthquake or ground subsidence, can utilize the foundation gripping device attached under the foundation concrete again to lift the building with a hydraulic jack and repair the tilt of the building. [Means for solving the problem]

[0006] In order to solve this problem, the invention described in claim 1 provides a subsidence correction machine for attaching to and lifting the foundations of buildings that have unequal settlement, comprising a foundation gripping tool formed in a roughly L-shape for being placed under the foundation concrete and for lifting the foundation concrete, and a hydraulic jack installation member for lifting the foundation gripping tool, which is attached to the multiple holes in the reinforcing H-shaped steel that is placed vertically and has multiple holes drilled in one flange of the reinforcing H-shaped steel with bolts and nuts so that it can be moved up and down, In order to install a hydraulic jack on the ground surface, a U-shaped steel plate for the hydraulic jack, made by forming a flat steel plate into a U-shape, is placed on the upper flange of the earth pressure dispersing H-steel, which is arranged with the flanges facing up and down, and a hydraulic jack is placed on the top surface of the steel plate for the U-shaped hydraulic jack. In order to assemble the steel plate for the U-shaped hydraulic jack to the earth pressure dispersing H-steel, a separation prevention member is formed so that the left and right folded parts of the steel plate for the U-shaped hydraulic jack and the lower flange of the earth pressure dispersing H-steel are sandwiched in a roughly U-shape, and the upper flange of the earth pressure dispersing H-steel and the flange of the reinforcing H-steel are fixed with a separation prevention member formed in a roughly L-shape so that the earth pressure dispersing H-steel does not come off from the reinforcing H-steel.

[0007] The invention described in claim 2 has the structure described in claim 1, and is characterized in that the foundation gripping device supports a foundation receiving base, which has a coarse-filed steel plate attached to the upper surface of a flat base steel plate, at a right angle with two base support steel plates formed into a roughly trapezoidal shape, and the base support steel plates are welded to the left and right flanges of an anchor bolt mounting member formed from channel steel, and a load-bearing steel plate formed into a square shape from a flat steel plate is welded to the tips of the left and right flanges of the anchor bolt mounting member.

In order to fix the uneven settlement correction device 1 to the bottom of the foundation concrete 3, the soil around the foundation concrete 3 is excavated, and the foundation gripping device 7 is inserted into the bottom of the foundation concrete 3, and the foundation gripping device 7 is fixed to the foundation concrete 3 with a plurality of anchor bolts 21 shown in FIG. 2. A foundation gripping device lifting member 45 consisting of a reinforcing H-shaped steel (A) 46, a reinforcing H-shaped steel (B) 47, and a hydraulic jack installation member 48 shown in FIG. 4 is attached to the foundation gripping device 7 thus fixed to the foundation concrete 3, and a hydraulic jack installation member 99 shown in FIG. 8 is installed on the ground surface 4 in order to attach a hydraulic jack 6 to the foundation gripping device lifting member 45. This state is shown in a front view.

[0017] Figure 1b shows the state in which the hydraulic jack 6 described in Figure 1a is operated to raise the foundation gripping device lifting member 45 (shown in Figure 4) attached to the foundation gripping device 7, thereby raising the foundation gripping device 7 fixed to the foundation concrete 3 and returning the building 2 to a horizontal position.

[0018] Fig. 2 shows the foundation gripping tool 7 explained in Fig. 1 in a perspective view, and Fig. 3 shows the foundation gripping tool 7 shown in Fig. 2 in an exploded view. The foundation gripping tool 7 is formed by welding two rectangular supporting steel plates (A) 15 and (B) 17, each 12 mm thick, approximately 80 mm wide and 100 mm long, to the tops of the left and right flanges (A) 29 and (B) 20 of the anchor bolt mounting member 12 formed from a channel steel having a thickness of 6 mm, a web width of 125 mm, a flange width of 65 mm and a length of approximately 500 mm. A rectangular anti-tip steel plate 18 measuring 12 mm thick, 50 mm long, and 225 mm wide is welded to the flange tip 22 at the bottom of the anchor bolt mounting member 12. A rectangular load-bearing steel plate 25 measuring 12 mm thick, 270 mm long, and 125 mm wide is welded to the flange tip 22 at the bottom of the anchor bolt mounting member 12. Furthermore, a ... A pair of pedestal support steel plates (A) 26 and (B) 23 are welded together, and a rectangular flat pedestal steel plate 30 with a thickness of 12 mm, length of approximately 150 mm, and width of approximately 225 mm is welded to the upper ends 40 (shown in FIG. 3) of the two pedestal support steel plates (A) 26 and (B) 23 thus constructed. Furthermore, to prevent the foundation concrete 3 and the flat pedestal steel plate 30 described in FIG. 1 from sliding when the hydraulic jack 6 is operated, a rough file-shaped steel plate 13 formed from a rough file-shaped steel plate is welded to the upper surface of the flat pedestal steel plate 30. In addition, in order to firmly fix the foundation gripping device 7 to the foundation concrete 3, a plurality of anchor bolt holes 28 are drilled in the web 16 of the anchor bolt mounting member 12, a plurality of anchor bolts 21 are inserted into the anchor bolt holes 28, and the anchor bolts 21 are driven into the foundation concrete 3, thereby fixing the foundation gripping device 7 to the foundation concrete 3. In addition, it is preferable to use a chemical anchor bolt as the anchor bolt 21 in order to increase its strength. In the present invention, an M16 size cut bolt having a length of 170 mm, a chemical anchor (resin capsule), and an M16 nut were used.

[0019] FIG. 4 shows a foundation gripping tool lifting member 45 for lifting the foundation concrete 3 by being attached to the foundation gripping tool 7 described in FIG. 1 and FIG. The foundation gripping device lifting member 45 is formed by forming a plurality of holes 49, 50, 55, 56 in one flange (A) 54, 57 of the two parallel reinforcing H-shaped steels (A) 46, (B) 47, each of which is made of an H-shaped steel having a length of 100 mm, a width of 100 mm, a web thickness of 6 mm, a flange thickness of 8 mm, and a length of 1100 mm. In order to fix the flanges (C) 64 and (D) 65 of the two reinforcing H-shaped steels (A) 46 and (B) 47 in parallel, both ends of the two reinforcing steel plates (A) 60, (B) 63, each of which is made of a flat steel plate having a thickness of 12 mm, a length of approximately 150 mm, and a width of approximately 340 mm, are aligned approximately flush with the lower ends of the flanges (C) 64 and (D) 65 so as to be flush with the flanges (C) 64 and (D) 65. The figure shows two receiving members (A) 52 and (B) 53, each having a thickness of 12 mm, a height of approximately 50 mm and a length of approximately 540 mm, welded to the two reinforcing steel plates (A) 60 and (B) 63 welded to the flanges (C) 64 and (D) 65 at two points, one at the top and one at the center. Furthermore, anti-detachment fittings (A) 59 and (B) 62 shown in FIG. 6 are welded to the left and right centers of the receiving members (A) 52 and (B) 53. Furthermore, the figure shows a state in which a hydraulic jack installation member 48 is fixed with bolts and nuts to multiple holes 49, 50, 55, 56 drilled in one of the flanges (A) 54 and (B) 57 of the reinforcing H-shaped steel (A) 46 and the reinforcing H-shaped steel (B) 47.

[0020] Figure 5 is a perspective view showing the two reinforcing H-shaped steel (A) 46, reinforcing H-shaped steel (B) 47, and hydraulic jack installation member 48, which are described in Figure 4, separated from each other. The reason why the hydraulic jack installation member 48 is configured to be vertically movable with respect to the two reinforcing H-shaped steel (A) 46, reinforcing H-shaped steel (B) 47 using a plurality of bolts 69, bolts 68, nuts 51, and nuts (not shown) is that, even for buildings constructed on the same site, the ground surface may be inclined rather than horizontal with respect to the position of the foundation concrete due to differences in elevation of the land caused by sloping land, etc.

[0021] 6 is a perspective view showing the two reinforcing H-shaped steel (A) 46, the reinforcing H-shaped steel (B) 47, and the hydraulic jack installation member 48 described in FIG. 4, as viewed from the opposite side. A receiving member (B) 53 having a thickness of 12 mm, a length of about 50 mm, and a width of about 540 mm is welded to the lower end 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 so that the lower ends of the flanges (C) 64 and (D) 65 are flush with the lower end of the receiving member (B) 53. The receiving member (B) 53 is disposed approximately 500 mm from the lower ends of the flanges (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 receiving member (A) 52, which is 12 mm thick, approximately 50 mm long and 540 mm wide, is welded to the left-right center of receiving member (A) 52 and receiving member (B) 53 thus welded, and the approximately 50 mm lower half of anti-detachment fitting (A) 59 and anti-detachment fitting (B) 62, which are made by bending approximately the upper half of a flat steel plate 6 mm thick, approximately 100 mm long and 100 mm wide at an angle of approximately 30 degrees into a trapezoidal shape, are welded to the left-right center of receiving member (A) 52 and receiving member (B) 53 thus welded.

[0022] Furthermore, in order to clearly explain how the load-receiving steel plate 25 and the collapse prevention steel plate 18 of the foundation gripping tool 7 described in Fig. 2 are connected to the receiving member (A) 52, receiving member (B) 53, and the removal prevention metal fitting (A) 59 and removal prevention metal fitting (B) 62 of the foundation gripping tool lifting member 45 in order to lift the foundation gripping tool 7 installed under the foundation concrete 3 described in Fig. 1, Fig. 6 shows the load-receiving steel plate 25 (shown by dotted lines) and the collapse prevention steel plate 18 (shown by dotted lines) described in Fig. 2 and Fig. 3 connected to the upper part (A) 76 of the receiving member (A) 52 and the upper part (B) 77 of the receiving member (B) 53. Note that the upper half of the removal prevention metal fitting (A) 59 and the removal prevention metal fitting (B) 62 are bent by about 30 degrees in the direction of the foundation gripping tool 7 described in Fig. 1 so that they can be easily connected to the load-receiving steel plate 25 and the collapse prevention steel plate 18.

[0023] 7a of FIG. 7 shows a perspective view of the hydraulic jack installation member 48 described in FIG. 5. FIG. 7b shows an exploded view of the hydraulic jack installation member 48 described in FIG. 7a. The hydraulic jack installation member 48 is formed by bending both vertical sides of a flat steel plate 6 mm thick, approximately 310 mm long, and approximately 540 mm wide in the same direction at right angles by approximately 30 mm into a U-shape to form a U-shaped reinforcing mounting steel plate 80, and forming a plurality of holes 71, 82, 83, and 84 on the left and right sides of a web 81 of the U-shaped reinforcing mounting steel plate 80 at positions corresponding to the plurality of holes 49, 50, 55, and 56 formed in the flanges (A) 54 and (B) 57 described in FIG. 4 and FIG. 5, and further forming a 1 mm thick hole for welding to the left and right sides of the web 81. Two reinforcing trapezoidal steel plates (A) 72 and (D) 75 are formed into a roughly trapezoidal shape with a thickness of 12 mm, a bottom base of about 250 mm, an upper base of about 40 mm, and a height of about 125 mm. Two reinforcing trapezoidal steel plates (B) 73 and (C) 74 are further formed into a roughly trapezoidal shape with a thickness of 12 mm, a bottom base of about 250 mm, an upper base of about 80 mm, and a height of about 155 mm to be welded between the reinforcing trapezoidal steel plates (A) 72 and (D) 75. A reinforcing triangular steel plate (A) 89, which is a flat steel plate 6 mm thick, approximately 140 mm wide, and 330 mm long, bent into an L-shape to be welded to the base of the web 81, is sandwiched between the reinforcing trapezoidal steel plate (C) 74 and the reinforcing trapezoidal steel plate (D) 75, and a reinforcing triangular steel plate (B) 91, which is a flat steel plate 6 mm thick, approximately 140 mm wide, and 330 mm long, bent into an L-shape to be welded to the base of both sides of the bent web 81, is sandwiched between the reinforcing trapezoidal steel plate (B) 73 and the reinforcing trapezoidal steel plate (C) 74, and a reinforcing trapezoidal steel plate 12 mm thick is welded between the reinforcing trapezoidal steel plate (B) 73 and the reinforcing trapezoidal steel plate (C) 74 so that it is parallel to the ground surface. The figure shows an oblique view of a hydraulic jack top plate 88 formed from a flat steel plate measuring 155 mm in height and 130 mm in width, two triangular reinforcing plates (A) 86 and (B) 87 formed from flat steel plate measuring 12 mm in thickness, 136 mm in height and 142 mm in width in a roughly right-angled triangle shape which are welded to the top surface of the hydraulic jack top plate 88 for reinforcement, and a top plate reinforcing steel plate 90 formed from a flat steel plate measuring 12 mm in thickness, 130 mm in width and 170 mm in length which are welded to the hypotenuses of the two further triangular reinforcing plates (A) 86 and (B) 87 for reinforcement.

[0024] 8 and 9 explain the earth pressure dispersion H-shaped steel 5 for supporting the hydraulic jack 6 explained in Fig. 1. The hydraulic jack 6 explained in Fig. 1 is a product with a lifting capacity of 30 tons, and in order to reduce the hydraulic jack 6 sinking into the ground when it is operated and operate it in a stable state, a U-shaped hydraulic jack steel plate 102 is placed under the hydraulic jack 6, the U-shaped steel plate 102 being made by bending both sides of the vertical direction of the flat steel plate, which is 6 mm thick, approximately 260 mm long and approximately 300 mm wide, at right angles by approximately 30 mm into a U-shape to form a bent part (A) 137 and a bent part (B) 143. Further, the flanges of the earth pressure dispersion H-shaped steel plate 5 formed from an H-shaped steel plate having 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 above and below the steel plate 102 for the U-shaped hydraulic jack, and a plurality of holes are formed in the bent portion (A) 137 and the bent portion (B) 143 of the steel plate 102 for the U-shaped hydraulic jack. In order to assemble the steel plate 102 for the U-shaped hydraulic jack thus formed to the earth pressure dispersion H-shaped steel plate 5, the steel plate 102 is placed in a manner as shown in the exploded view of FIG. As shown in FIG. 10, a plurality of holes 135 are formed in the bent portion (A) 137 of the steel plate 102 for the U-shaped hydraulic jack, and a plurality of holes 136 are also formed in the bent portion (B) 143. The bottom plate (A) 132 of the member (A) 131 for preventing detachment, which is configured to be roughly L-shaped by welding the bottom plate (A) 132, the reinforcing plate (A) 130 and the diagonal reinforcing plate (A) 127 shown in FIG. 10, is inserted under the lower flange 105 of the H-shaped steel 5 for dispersing earth pressure, and a plurality of bolts 134, The bent portion (A) 137 and the anti-detachment member (A) 131 are fixed with nuts 128, and similarly, the bent portion (B) 143 of the steel plate 102 for the U-shaped hydraulic jack and the anti-detachment member (B) 103 are fixed with multiple bolts 133 and nuts 141, thereby showing the state in which the H-shaped steel plate 102 for the U-shaped hydraulic jack, the anti-detachment member (B) 103 and the anti-detachment member (A) 131 sandwich and fix the earth pressure distribution H-shaped steel plate 5.The reason for sandwiching the earth pressure distribution H-shaped steel plate 5 between the U-shaped hydraulic jack steel plate 102, the anti-detachment member (B) 103 and the anti-detachment member (A) 131 in this manner is to increase the contact 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 earth pressure distribution H-shaped steel plate 5, and to make the length and width dimensions of the base plate (A) 132 and base plate (B) 138 that constitute the anti-detachment member (A) 131 and the anti-detachment member (B) 103 wider than the width (200 mm) of the flange of the earth pressure distribution H-shaped steel plate 5, thereby distributing and receiving the force of the hydraulic jack 6 applied to the earth pressure distribution H-shaped steel plate 5 widely over the entire ground surface.

[0025] 9 shows a state where a plurality of earth pressure distribution L-shaped steel plates 110, each of which is a flat steel plate 6 mm thick, approximately 300 mm long, and approximately 600 mm wide, with one lateral end bent at a right angle by approximately 50 mm, are laid under the earth pressure distribution H-shaped steel 5 in order to distribute the force of the hydraulic jack 6 against the ground surface 4 described in FIG. 1 and prevent the hydraulic jack installation member 99 from sinking into the ground. By laying the ends of a plurality of earth pressure distribution L-shaped steel plates 110 continuously in an overlapping manner under the earth pressure distribution H-shaped steel 5 in this way, it has become 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] Fig. 10 is an exploded view showing the disassembled state of the hydraulic jack installation member 99 described in Fig. 8. The separation prevention member (A) 100 for keeping the foundation gripping tool lifting member 45 described in Fig. 4 at a fixed distance from the earth pressure dispersing H-shaped steel 5 described in Fig. 8 so as not to separate is a flat steel plate 12 mm thick, approximately 140 mm long and approximately 100 mm wide, and has a plurality of holes 114 and 117 formed in positions opposite to the plurality of holes 49 and 50 formed in the flange (A) 54 of the reinforcing H-shaped steel (A) 46 described in Fig. 4. The opposite sides of a support plate (A) 118 made of a flat steel plate 12 mm thick, approximately 120 mm long and 210 mm wide and shaped into an approximately right-angled triangle are welded to the left and right central parts of the plate (A) 113 and the backing plate (A) 113, and a fall-prevention plate (A) 119 made of a flat steel plate 6 mm thick, approximately 50 mm long and 50 mm wide and shaped by bending the top and bottom central parts at an angle of approximately 10 degrees into a L-shape is welded to the tip of the support plate (A) 118. The fall-off prevention plate (A) 119 of the separation prevention member (A) 100 thus configured is hooked onto the end of the upper flange 104 of the earth pressure prevention H-shaped steel 5, the adjacent side of the support portion (A) 118 is pressed against the upper flange 104, and the multiple holes 114 and holes 117 formed in the backing plate (A) 113 are abutted against the holes 49 and holes 50 formed in the flange (A) 54 described in FIG. 4 in a position corresponding thereto, and the separation prevention member (A) 100 is secured to the end of the H-shaped steel 5 for preventing earth pressure by the multiple bolts 78, bolts (not shown) and nuts 115 and nuts 116. By fixing member (A) 100 to flange (A) 54 of reinforcing H-shaped steel (A) 46 described in Figure 4, and similarly fixing the anti-separation member 101 to the reinforcing H-shaped steel (B) 47 described in Figure 4 with multiple bolts 79 and nuts 122, the earth pressure prevention H-shaped steel 5 is fixed so that it does not come off from the reinforcing H-shaped steel (A) 46 and the reinforcing H-shaped steel (B) 47 even when the hydraulic jack 6 is operated and the foundation gripping device lifting member 45 described in Figure 4 is lifted.

[0027] Figure 11 is an oblique view to clearly show the positional relationship between the foundation gripping device 7 described in Figure 2, the foundation gripping device lifting member 45 described in Figure 4, and the hydraulic jack mounting member 99 described in Figure 8.
