Description

  The present invention relates to a pile driving support device for driving a pile for forming a scaffold, a fence, and the like for construction, civil engineering work and the like to the ground.

  Conventionally, pile driving work such as single pipe pipes associated with construction, civil engineering work, etc. has been done by two people, one person holding the pile vertically with the hand and the other with a hammer on the head of the pile. He strikes and drives the pile into the ground. For this reason, there is a risk of hitting the hand with a hammer accidentally. In addition, the metal pipe is overheated by sunlight in the summer, and the metal pipe is overcooled in the winter, which makes it difficult to support by hand.

Then, some support tools for supporting the pile to drive in are proposed (patent documents 1-3).
Japanese Utility Model Publication No. 63-121648, FIG. No. 3026942, FIG. 1, paragraphs 0010 to 0011 Japanese Patent Laid-Open No. 2002-4586, FIG. 1, paragraphs 0007 to 0011

  However, in the conventional pile driving support described above, since the work of setting the pile on the support is necessary, the workability is poor, and the angle of the pile with respect to the ground is finely adjusted during the pile driving work. There is a problem that can not be.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a pile driving support device that can improve pile driving workability while ensuring safety.

  The pile driving support device according to the present invention is a pile driving support device for supporting a pile driven into the ground, and is provided with a rod-shaped handle portion and a holding member provided at the tip of the handle portion to hold the pile. And a section.

  The pile is, for example, a metal pipe. In this case, it is desirable that the holding unit includes a magnet that holds the metal pipe by suction from the side surface. Further, in this case, it is more preferable that the holding portion includes a U-shaped pipe presser that arranges the magnet inside and sandwiches the metal pipe from the side surface.

  In addition, the holding part may be an annular member into which the pile is inserted. Furthermore, when the pile is a pipe, the holding portion may be a protective cap that is attached to the upper end of the pipe and protects the upper end of the pipe. The handle may be composed of a telescopic double tube.

  According to the pile driving support device according to the present invention, since the holding portion for holding the pile is provided at the tip of the rod-shaped handle portion, when the pile is driven into the ground, the hand is accidentally hit with a hammer. There is no danger, and even during pile driving work, the posture of the pile can be adjusted by the holding part through the handle part, so workability is improved.

  FIG. 1 is a front view in which a part of a pile driving support device 1 according to the first embodiment of the present invention is omitted, FIG. 2 is a plan view thereof, and FIG. 3 is a cross-sectional view taken along line A-A 'of FIG.

  The support device 10 of this embodiment includes a handle portion 11 and a holding portion 12 provided at the tip of the handle portion 11.

  The handle portion 11 has a double-pipe structure of a first metal pipe 13 and a second metal pipe 14 having a larger diameter than that of the first metal pipe 13 that is sheathed by the first metal pipe 13. A slit 13a extending in the axial direction of the pipe is formed on the proximal end side of the first metal pipe 13, and a hole 14a is formed in the second metal pipe 14 corresponding thereto. A metal stopper pin 14b whose tip is fitted into the slit 13a is inserted into the hole 14a and is fixed by welding. Therefore, the second metal pipe 14 can slide with respect to the first metal pipe 13 only within a range in which the stopper pin 14b can move in the slit 13a. Thereby, the handle | steering-piece part 11 becomes a structure which can be expanded-contracted in the predetermined range. The outer surface of the second metal pipe 14 is covered with an insulator coating 15 such as rubber or resin. The insulating coating 15 is used to enhance safety against slipping and lightning strikes.

  The holding portion 12 has a metal U-shaped pipe presser 16 with the opening side facing the tip of the handle portion 11 in a direction perpendicular to the axial direction of the handle portion 11, and the opening side inside the pipe presser 16. A U-shaped magnet 19 fixed by bolts 17 and nuts 18 in the same direction as the opening side of the pipe presser 16 is provided. The magnet 19 adsorbs and supports the metal single pipe 2 as a pile from the side. The pipe retainer 16 supports the single pipe 2 so as to be sandwiched from both sides, and makes it possible to adjust the position, inclination, etc. of the single pipe 2.

  FIG. 4 is a perspective view for explaining a pile driving operation using the above-described pile driving support device 10.

  As illustrated, the worker 1 uses the support device 10 to hold the single pipe 2 as a pile so as to be perpendicular to the ground 4. A protective cap 5 for preventing damage to the head 2 a is attached to the head 2 a of the single pipe 2. The operator 3 hits the top of the protective cap 5 with a hammer 6 and drives the single pipe 2 into the ground 4.

  Thus, if the support instrument 1 of this embodiment is used, it will be prevented that the operator 3 hits the hand etc. of the operator 1 accidentally with the hammer 6, and safety can be improved. In addition, since the holding unit 12 is provided with a magnet 19 and the pipe presser 16 controls the magnet 19 and the direction in which the single pipe pipe 2 is attracted, the single pipe 2 is finely adjusted in all directions. Can do. For this reason, since the worker 1 can finely adjust the angle of the single pipe 2 with respect to the ground 4 using the support device 10 in all directions even during work, the workability of the pile driving work is greatly improved. . Furthermore, since the handle | steering-piece part 11 can be expanded-contracted, since it can operate | work after adjusting the support instrument 10 to the length which worker 1 can work most easily, workability | operativity improves further.

  FIG. 5 is a perspective view showing a pile driving support device 20 according to the second embodiment of the present invention.

  The support device 20 of this embodiment includes a rod-shaped handle portion 21 and an annular holding portion 22 provided at the tip of the handle portion 21. The holding part 22 holds the single pipe pipe 22 by inserting the single pipe pipe 22 inside. According to this embodiment, the support device 20 can be created at a lower cost than in the previous embodiment.

  FIG. 6 is a perspective view showing a pile driving support device 30 according to the third embodiment of the present invention.

  The support device 30 of this embodiment includes a rod-shaped handle portion 31 and a protective cap-shaped holding portion 22 provided at the tip of the handle portion 31. The holding portion 22 includes a large diameter portion 33 in which the tip of the handle portion 11 is fixed to a side surface, and a small diameter portion 34 that projects coaxially from the lower surface of the large diameter portion 33. According to the support device 30, the holding portion 22 can be attached to the head of the single pipe 2 by inserting the small diameter portion 34 of the holding portion 22 into the head 2 a of the single pipe 2. By hitting the diameter portion 33 with the hammer 6, the holding portion 22 also serves as a protective cap.

  In addition, the present invention can be implemented with various modifications without departing from the scope of the invention.
