Abstract

PURPOSE:To dispense with the climbing to a steel pipe upper part at pin insertion by mounting a steel pipe falling preventing stopper on a cap of accessory in construction method of steel pipe press-in. CONSTITUTION:A groove slightly broader than the diameter of an attachment bar 4 is cut from the lower part of a rotating press-in auxiliary tool 1 to the center part, and a stopper bar 2 and a stopper 3 are mounted in prescribed positions of the groove upper part and lower part. A hole is bored in a steel pipe, the bar 4 is inserted thereto, and a stopper pin 5 is mounted on the inner part of the steel pipe to fix the bar 4 to the steel pipe. When such a steel pipe having the bar 4 fixed thereto is suspended by a winch, and moved from the lower part of the auxiliary tool 1 to the upper part, the stopper bar 2 is raised to the upper part, and then dropped in the direction of the stopper 3 in the lower part. Thus, the bar 4 fixed to the steel pipe is stopped without being dropped down from the stopper bar 2. After the steel pipe is rotated and pressed in, the stopper bar 2 is lifted to remove the stopper pin 5 of the bar 4 from the steel pipe.

[Prior Art] The conventional steel pipe rotary press-fit pile method uses an earth auger, attaches a cap that matches the size of the steel pipe to the portion of the earth auger below the motor, and pre-drill a hole in the steel pipe. It is a construction method in which the placed steel pipe is caught by a winch, inserted, the rod is inserted into the hole of the cap and the hole of the steel pipe, and the steel pipe is press-fitted. However, in order to insert the rod into the steel pipe and cap, it is necessary to climb up to about 6 m with a winch of an earth auger and swing up to the top.

[Problems to be Solved by the Invention] In order to press-fit a steel pipe with an earth auger, a person must go up to the upper part of the steel pipe and insert a rod, regardless of whether the steel pipe is 3 m or 6 m. It is extremely dangerous for a human to ride on a swing and climb with a winch above the steel pipe.

[Means for Solving the Problem] In consideration of the present situation as described above, an auxiliary tool for the steel pipe rotary press-fitting method of the present invention has been considered and completed, and its feature is that human beings reach the upper part of the steel pipe,
The winch eliminates the danger of having to get on the swing and climb up. This led to the invention of a steel pipe cap aid. The outer shape of the cap may be square, hexagonal, octagonal or round, but the inner shape must be the shape of a steel pipe. Also, the rod to be inserted into the steel pipe does not come off from the steel pipe, so it suffices to attach a pin to the rod, so that it will not come off from the steel pipe and will not fall even when fishing with a winch or standing up. .

[Embodiment] The present invention will be described in more detail based on an embodiment shown in the drawings. FIG. 1 is a side view of an auxiliary tool (1) for a steel pipe rotary press-fit pile method of the present invention. The conventional auxiliary tool only has a hole for inserting the round bar (4) shown in Fig. 4 in the center, and on this hole, take a swing with an earth auger and catch it with a winch to match the hole of the steel pipe with the hole of the auxiliary tool. Insert the round bar (4). Therefore, it is very dangerous because you have to take a swing and climb to the upper part (6 m) of the earth auger with a winch. In order to eliminate this risk, the steel pipe rotary press-fitting method of the present invention is equipped with a stopper rod (2) shown in FIG. 1 and a groove slightly thicker than the diameter of the rod (4) up to the center. A stopper (3) is attached to the lower part and the upper part of 1).
In addition, if you make a hole in the steel pipe, insert the rod (4) shown in Fig. 4 and install the stopper pin (5) shown in Fig. 4 inside the steel pipe,
The rod (4) is fixed to the steel pipe. In this way, the steel pipe to which the rod (4) of Fig. 4 is fixed is fished with a winch, and the lower portion of the auxiliary tool (1) of the steel pipe rotary press-fit pile method of Fig. 1 ([rod 4]
If you move it above, the stopper bar (2) will move to the upper part of the auxiliary tool (1). It stops until 3), but there is a stopper (3) inside the vertical, so the stopper rod (2) naturally
Falls in the direction of the lower stopper (3). Due to the lower stopper (3), the stopper bar (2) stops here. As a result, the rod (4) fixed to the steel pipe stops here without falling than the stopper rod (2). Therefore, the steel pipe can be picked up and is an auger and can be moved anywhere. In this way, the steel pipe is press-fitted while rotating, so even if it is pressed down from above, the rod (4) fixed to the steel pipe at this time moves to the grooved upper part of the auxiliary tool (1), but the steel pipe is press-fitted. There is no problem.
Rotate press fit the steel pipe, and when finished, lift the stopper rod (2) to the upper part and push the stopper pin (5) of the rod (4) from the steel pipe.
You can remove it. This way, you don't have to climb as high as 6th place to get on the swing and insert the rod (4) into the hole in the steel pipe with a winch. Therefore, the auxiliary tool of the steel pipe rotary pile construction method of the present invention was invented. [Effects of the Invention] According to the present invention, it is possible to eliminate the risk that a person at a height of 3 m to 6 m has to go up on a swing with a winch and insert the rod (4).
