Description

This invention relates to a set of a pile consisting of a rod-shaped member with one end driven into the ground to form a building structure, and a striking member for driving the pile.

When constructing protective fences or fences to protect against pests, rod-shaped members such as reinforcing bars are sometimes driven into the ground to serve as supports (Patent Document 1, etc.)

Here, in order to use the reinforcing bars as supports, one end must be driven deep into the ground until it reaches a sufficient supporting layer (e.g., 1 m).

JP 2006-115793 A

For example, if a fence post is 2m long, one end of a long reinforcing bar needs to be buried in the ground. To bury one end of the reinforcing bar in the ground, a striking force is applied to the other end of the reinforcing bar, and the other end of the reinforcing bar is driven into the ground, but this driving is usually done with heavy objects such as hammers or special tools, which places a heavy burden on the worker. There have also been cases where the reinforcing bar (especially the striking part) has been deformed. There have also been other problems, such as the need to work at high altitudes, which is dangerous, when driving long objects.

The purpose of this invention is to provide a pile and a pile installation set consisting of a reinforcing bar and a striking member, in which a reinforcing bar (rod-shaped member) can be easily driven into the ground and then connected to other reinforcing bars (rod-shaped members) to make a longer pile.

In order to solve the above-mentioned problems, the invention described in claim 1 uses a technical means for a pile comprising a rod-shaped member having one end driven into the ground, and a connecting member for connecting another rod-shaped member to the other end of the rod-shaped member, the connecting member covering the other end of the rod-shaped member and comprising a rod-shaped member inserting section into which one end of the other rod-shaped member can be inserted, and a fixing member connecting the rod-shaped member to the other rod-shaped member via the rod-shaped member inserting section, applying a striking force to the other end of the rod-shaped member via a striking member insertable into the rod-shaped member inserting section, driving one end of the rod-shaped member into the ground, and then inserting one end of the other rod-shaped member into the rod-shaped member inserting section, and connecting the rod-shaped member to the other rod-shaped member via the fixing member.

The invention described in claim 2 uses the technical means in which the rod-shaped member and the other rod-shaped member in the pile described in claim 1 are reinforcing bars.

The invention described in claim 3 uses a technical means of a pile installation set comprising the pile described in claim 1 or claim 2 and the striking member.

The pile of this invention involves driving a short reinforcing bar (rod-shaped member) into the ground, so one end of the reinforcing bar can be easily driven into the ground and installed. It can also be connected to other reinforcing bars with a fixing member to form a long reinforcing bar structure. A striking force is applied to the other end of the reinforcing bar via a striking member that can be inserted into the rod-shaped member insertion portion, and the reinforcing bar is driven into the ground, preventing deformation of the end of the reinforcing bar. The rod-shaped member insertion portion acts as a guide for the striking member, so the pile can be driven safely and easily.

The piles and pile installation set in this embodiment will be described with reference to Figures 1 and 2.

(Pile configuration)
1 and 2, a pile 1 includes a rod-shaped member and a connecting member 11 for connecting another rod-shaped member. In this embodiment, a reinforcing bar 10 is used as the rod-shaped member.

The reinforcing bar 10 has one end 10a that is driven into the ground and is pointed toward the tip. The other end 10b is flat.

The connection member 11 is attached to the other end 10b of the reinforcing bar 10 by a welded portion 11c. The connection member 11 covers the other end 10b of the reinforcing bar 10 and is formed in a cylindrical shape with an inner diameter slightly larger than the outer diameter of the reinforcing bar 10, into which one end of another reinforcing bar can be inserted.

In the figure, 11a is a rod-shaped member insertion section into which one end of another reinforcing bar can be inserted. A fixing hole 11b for fixing the reinforcing bar is formed through the side of the rod-shaped member insertion section 11a toward the outside. The fixing hole 11b is threaded so that a fixing member 11d such as a bolt can be screwed in.

The striking member 2 has an insertion portion 20 that can be inserted into the rod-shaped member insertion portion 11a of the connecting member 11, and a striking portion 21 that is provided at one end of the insertion portion 20 and is used to apply a striking force.

The insertion portion 20 is formed into a cylindrical shape with a length L that is longer than the depth of the rod-shaped member insertion portion 11a of the connection member 11. In this embodiment, the striking portion 21 is formed into a cylindrical shape with a larger diameter than the insertion portion 20 so that it is easier to apply striking force.

As a result, when the insertion portion 20 of the striking member 2 is inserted into the rod-shaped member insertion portion 11a of the connecting member 11, the striking portion 21 is separated from the connecting member 11 with the end of the insertion portion 20 in contact with the other end 10b of the reinforcing bar 10. In other words, when a striking force is applied to the striking member 2, the striking force is transmitted only to the other end 10b of the reinforcing bar 10, and not to the connecting member 11.

In addition, as long as an appropriate striking force can be applied to the other end 10b of the reinforcing bar 10, the striking member 2 can have various shapes, such as a straight rod that can be inserted into the rod-shaped member insertion portion 11a of the connecting member 11.

(How to install piles)
A method for burying one end of the pile 1 in the ground and erecting the pile 1 will be described with reference to Figs.

First, as shown in Figure 3 (A), place the pile 1 in the desired position and insert the insertion portion 20 of the striking member 2 into the rod-shaped member insertion portion 11a of the connecting member 11.

Next, as shown in FIG. 3(B), a striking force is applied to the striking portion 21 of the striking member 2 using a striking tool such as a hammer. This applies a striking force to the reinforcing bar 10, so that one end 10a of the reinforcing bar 10 can be driven into the ground to erect the pile 1.

Here, the striking force is transmitted only to the other end 10b of the reinforcing bar 10, and not to the connecting member 11. In addition, the other end 10b of the reinforcing bar 10 is surrounded and protected by the rod-shaped member insertion portion 11a of the connecting member 11, so even if a striking force is applied, the surrounding area is restrained and it does not deform. The rod-shaped member insertion portion 11a acts as a guide for the striking member 2, so the pile driving operation can be performed safely and easily.

Next, as shown in Figure 4 (A), the striking member 2 is removed from the erected pile 1, and one end of another reinforcing bar 3 is inserted into the rod-shaped member insertion portion 11a of the connecting member 11.

Then, as shown in FIG. 4(B), the reinforcing bar 3 can be connected to the pile 1 and lengthened by screwing the fixing member 11d through the fixing hole 11b to tighten the reinforcing bar 3.

(Example of change)
In this embodiment, a reinforcing bar 10 is used as the rod-shaped member, but the present invention is not limited to this as long as it can be driven into the ground, and for example, a plastic rod-shaped member used for gardening can also be used. Also, the end 10a forming the tip does not have to be sharp.

(Effects of the embodiment)
According to the pile 1 and pile installation set of the present invention, a short reinforcing bar 10 (rod-shaped member) is driven into the ground, so that one end 10a of the reinforcing bar 10 can be easily driven into the ground and installed. In addition, the reinforcing bar 10 can be connected to another reinforcing bar 3 by a fixing member 11d to form a long reinforcing bar structure. Since the reinforcing bar 10 is driven into the ground by applying a striking force to the other end 10b of the reinforcing bar 10 via the striking member 2 that can be inserted into the rod-shaped member insertion portion 11a, deformation of the end of the reinforcing bar 10 can be prevented. Since the rod-shaped member insertion portion 11a serves as a guide for the striking member 2, the pile driving operation can be performed safely and easily.
