Description

  The present invention relates to a spiral pile upright.

  Conventionally, spiral piles have been erected on the ground in various situations, such as installing a greenhouse in a field. When the spiral pile was erected, a rod-like handle was inserted into the ring-shaped mounting portion of the head of the spiral pile, and the handle was pushed downward and screwed in the horizontal direction. However, since the head of the spiral pile is in an eccentric position from the center of the spiral pile, the spiral pile at the beginning of screwing turns around the central axis of the pile, staggers and screwed into the ground at the desired angle It was difficult.

  As a solution to this problem, there was an auxiliary tool for driving a spiral pile described in Japanese Patent Application Laid-Open No. 2004-116273. This document is an auxiliary tool for driving a spiral pile, which has a spiral pile support portion that holds the spiral pile on the ground and has a tread protruding in the radial direction on the outer periphery of the other end of the spiral pile support portion. It was. Since there is a spiral pile support portion, it is possible to prevent wobbling of the pile at the beginning of screwing.

However, if there are other piles or struts near where the spiral pile is screwed in, this auxiliary tool for driving the pile will not rotate smoothly because the handle can be used with the pile or strut, and the position of the handle will be adjusted each time. There was a need to do.

  The spiral pile standing tool of the present invention will be described with reference to FIGS. As shown in the front view with a partially cut section in FIG. 1, the spiral pile standing tool of the present invention is a pile standing tool for standing the spiral pile X on the ground.

  The spiral pile X has a spiral X1 on the distal end side, that is, in the vicinity of the lower end (or lower end) at the time of standing, and an annular shape (not limited to an annular shape) on which a rod-like handle is detachably attached to the proximal end side, that is, the upper end. ) Mounting portion X3. In FIG. 1, the spiral X <b> 1 is shown as a pile in which a plate is spirally wound around the outer periphery on the distal end side of the spiral pile main body X <b> 2, but a spiral Y <b> 1 in which a rod material as shown in FIG. 7 is spirally wound is provided. It is good also as the spiral pile Y.

  The spiral pile erection tool of the present invention includes a handle 1 and a holding body 3. The handle 1 is rod-shaped and has a ratchet mechanism 2 at the center thereof. The ratchet mechanism 2 includes a gear 2b having a large number of teeth on the outer periphery of the fitting hole 1a, a claw 2e provided with two switching projections 2c that mesh with the gear 2b, a rotating shaft 2d of the claw 2e, and a pressing pin. 2j and an elastic body 2f. The pressing pin 2j is urged by the elastic body 2f to press the claw 2e, but the rotation direction of the gear 2b is reversed between pressing one of the claw 2e and pressing the other.

  The holding body 3 includes a holding body 4 that is attached to and detached from the head of the spiral pile main body X2, and a locking and fixing member 5 that holds the handle 1 and the spiral pile X at a substantially right angle. The holding body 4 has an inverted flat container shape having an opening 4a at the lower end and a polygonal protrusion 4b that fits into the fitting hole 1a of the handle 1 at the upper end.

  FIG. 2 is a plan view showing a main part of the handle 1 when the fixture of FIG. 1 and the upper lid 1c are removed. As shown in this figure, the handle 1 has a polygonal (decagonal) fitting hole 1a at the center, and a ratchet mechanism 2 is attached around the fitting hole 1a. Both ends of the handle 1 are gripping portions 1d. The handle 1 is attachable to and detachable from the holding body 4. A polygonal hole is formed in the lower part of the ratchet mechanism 2, and the handle 1 is attached and detached by fitting a polygonal protrusion erected on the holding body 4 into this hole. The The handle 1 can be fixed by fitting the handle 1 to the holding body 4, holding it with the upper lid 1 c, and fixing it with the fixing member 1 b. In contrast to the above, a polygonal protrusion may be formed on the handle side, and a hole for fitting this protrusion may be formed in the holding body 4.

  The holding body 4 is attached to the head of the spiral pile main body X2, the handle 1 is attached to the holding body 4, and the handle 1 is rotated around the central axis of the spiral pile X so that the spiral on the lower end side of the spiral pile main body X2 The spiral pile X can be erected on the ground by rotating and rotating X1.

  When the attachment portion X3 of the spiral pile X is inserted from the opening 4a at the lower end of the holding body 4, since the head of the attachment portion X3 is round, the holding body 4 is inserted in a swingable state. When this swinging occurs, the handle 1 also swings, and it is difficult to screw in the spiral pile X. Therefore, the helical pile erection tool of the present invention is configured such that the rocking pile X can be stably screwed into the ground by stopping the swinging by the locking and fixing member 5. The locking and fixing member 5 that stops the swinging will be described below.

  FIG. 3 is a side view showing the spiral pile standing tool of the present invention. The locking and fixing member 5 includes a hanging body 5a attached to one side surface of the holding body 4 (in the figure, attached to the lower end of the back surface of the holding body but not related to the mounting position) by a hinge. Have. A projecting body 7 is provided at the lower end of the hanging body 5a. As shown in FIG. 4, the projecting body 7 has a recess 7a formed at the tip.

  When the attachment portion X3 is inserted into the holding body 4, the locking and fixing member 5 is rotated from the dotted line position to the solid line position, and the spiral pile main body X2 is locked at a position substantially perpendicular to the longitudinal direction of the handle 1. Fix it. The hinge shaft 6 has a coil spring 6a, and the lower end of the suspended body 5a presses and fixes the spiral pile main body X2 by the biasing force of the coil spring 6a. The spiral pile main body X2 is held in the recess 7a with almost no backlash, and the handle 1 is prevented from swinging.

  In addition, instead of the coil spring 6a, a leaf spring capable of pressing the spiral pile body X2 having the attachment portion X3 inserted into the holding body 4 by the projecting body 7 at the lower end of the hanging body 5a is attached to the back side of the holding body 4. Other methods such as using a leaf spring as the carrier 4 may be used. In FIG. 4, the polygonal protrusion 4 b at the upper end of the holding body 4 is shown as a hexagon, but it may be a polygon that can be fitted into the fitting hole 1 a of the ratchet mechanism 2 of the handle 1.

  When the mounting portion X3 of the spiral pile X is inserted into the holding body 4 of the spiral pile standing tool and the mounting portion X3 of the spiral pile X is fitted into the recess 7a of the projecting body 7 of the hanging body 5a, The helical pile body X2 fitted in the concave portion 7a of the projecting body 7 is pressed by the biasing force of the coil spring 6a or the leaf spring, which is an elastic body, and the holding body 4 and the helical pile X are fixed. Thus, the spiral pile X fixed to the holding body 4 fits the fitting hole 1a of the handle | steering-wheel 1 to the polygon protrusion 4b of the upper end of the holding body 4, and makes the front-end | tip of the spiral pile X into the desired position on the ground. While maintaining the insertion spiral pile X and the ground at a desired angle, the steering wheel 1 is rotated forward and backward repeatedly. Since there is a ratchet mechanism 2, the spiral pile X rotates only in the screwing direction, and when the handle 1 is reversed, the spiral pile X slips between the claw 2e and the gear 2b, and the spiral pile X does not reverse. In this way, the tip of the spiral pile X or the spiral X1 in the vicinity of the tip is screwed up to stand in the ground. At this time, even when the handle 1 hits another spiral pile X or a support in the vicinity, the rotation angle of the handle 1 can be appropriately adjusted, or the position of the handle 1 can be changed, so Can be repeated repeatedly, and the rotation operation is not hindered. If the forward rotation angle is larger than the angle of one gear 2b, the helical pile X can be rotated and screwed one by one.

  When pulling out the spiral pile X, the handle 1 is attached to the head of the spiral pile X in the same way as when screwing, and the pressing pin 2j is switched so as to press the other of the claws 2e. Thus, when the handle 1 is rotated, the spiral pile X is rotated only in the direction in which it is pulled out, is not rotated in the screwing direction, and can be extracted.

  In addition, the purpose of using the holding body 4 and the hanging body 5a as a hinge type or using the hanging body 5a as a leaf spring in the above embodiment is that when the attachment portion X3 of the spiral pile X is fitted into the holding body 4, the hanging body This is because it is easy to fit the attachment portion X3 of the spiral pile X into the concave portion 7a of the protruding body 7 by warping 5a away from the spiral pile main body X2. Even if the holding body 4 and the hanging body 5a are fixed, the ease of fitting is somewhat sacrificed, but the mounting portion X3 of the spiral pile X can be fitted into the concave portion 7a of the protruding body 7.

  FIG. 5: is a principal part perspective view which shows 2nd Example of the holder of the spiral pile standing tool of this invention. As shown in FIG. 5, instead of the suspended body 5 a, a fixed suspended body 8 in which the locking and fixing member 5 is fixed to the holding body 4 is provided, and the protruding portion 9 is projected on one side of the fixed suspended body 8. And the rotation fixing member 10 which formed the latching | locking part 9a (it showed by the recessed part in the figure) which latches the spiral pile main body X2 in the protrusion part 9, and was attached to one side of the protrusion part 9 so that rotation was possible. Install. It is also possible to house the spiral pile main body X2 in the locking portion 9a, hold it from the outside with the rotation fixing member 10, and hold the hook of the locking member 10a on the locking receiving member 10b to hold it down. Therefore, the protrusion 9 and the rotation fixing member 10 are sandwiching and fixing members that sandwich the spiral pile main body X2.

Installed. The handle 14b is pressed by a stretchable elastic body 15 (in the drawing, a coil spring) inserted into a hole drilled in one end of the projecting body 11, and its tip is positioned at the positioning portion 13c of the bolt 13. The positioning protrusion 14a of the member 14 is pressed and locked.

  The spiral pile body X2 is sandwiched and fixed by the inclined surface 13b of the bolt 13 fitted in the recess 11a of the protrusion 11 and connected to the through holes 12a and 12b of both ends 11b and 11c of the protrusion 11. Therefore, the projecting body 11 having the recess 11a and the bolt 13 having the inclined surface 13b are sandwiching and fixing members that sandwich the spiral pile body X2. When using the clamping and fixing member that sandwiches the spiral pile main body X2, the bolt 13 is pulled out from at least the through hole 12a on one side of the projecting body 11, and the spiral pile main body X2 in which the attachment portion X3 is inserted into the projecting body 4 is projected. 11 is inserted into the through holes 12a and 12b of both ends 11b and 11c of the projecting body 11 in a state of being fitted in the recess 11a of the protrusion 11 (the positioning member 14 in the state shown in the figure inserts the bolt 13 without being operated). Protrusions 14a are formed at an angle where they can be formed). When the bolt 13 is thus inserted, the protrusion 14a of the positioning member 14 is automatically locked or fitted into the positioning portion 13c of the bolt 13 and is sandwiched and fixed between the concave portion 11a of the projecting body 11 and the inclined surface 13b of the bolt 13. The When removing the spiral pile X, the handle 14b of the positioning member 14 is rotated to remove the protrusion 14a of the positioning member 14 from the positioning portion 13c of the bolt 13, and the base end 13a of the bolt 13 is grasped and pulled out.
