Abstract

PURPOSE:To permit the rotation force of a rotary drive source to transmit to a non-circular pile with good efficiency by providing a joint to connect the rotary drive source with a face-contact grasper to hold the non-circular pile. CONSTITUTION:A joint part 2 consisting of a base plate 21 and a spacer 23 between the base plate 21 and a round base 22, having the supply tube 31 of a supply path 3, is provided. A face-contact grasper 1 to hold a pile B through a through hole 11 and a ball core 12 is connected through the connecting hole C of a rotary drive source A and the fitting hole 22a of the joint part 2 to the drive source C by contacting it in such a way as to hold the upper end flange of the no-circular pile B made of H- or I-steel, etc. Water, cement mortar, etc., is supplied through a flexible hose 32 from the supply tube 31 to a water supply tube D.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a connection device between a non-circular pile body and a rotational drive source.

<Prior Art> Conventionally, as schematically shown in FIG. 2, there is no technology in which a non-circular pile body B such as an H-type steel or an I-type steel is directly rotated by a rotary drive source A and inserted into the ground.

Therefore, there was no connection device between the non-circular pile body B and the rotational drive source A.

OBJECTS OF THE INVENTION An object of the present invention is to provide a connection device for a non-circular pile body and a rotational drive source.

<Example> An example of the present invention will be described below with reference to the drawings.

Figure 2 shows an outline of an example of the use of the present invention in which a rotational drive source A and a non-circular pile body B are connected.

FIG. 1 is an explanatory diagram of an embodiment of the present invention that connects a rotational drive source A and a non-circular pile body B.
Type steel is used.

In addition, in FIG. 1, C located at the rotational drive source A represents a connection hole, and D located at the non-circular pile body B represents a water pipe.

In the present invention, a non-circular pile body B is grasped by a surface contact grasping body 1, and the surface contact grasping body 1 is attached to a joint portion 2 for connecting to a rotational drive source A.

Further, a supply waterway 3 is located in the joint portion 2 so that water or the like can be supplied to the water pipe.

Although the present invention will be explained using water, it is also possible to use mortar, bentonite, air, etc., or a mixture of these in addition to hydraulics, and in this case, water pipes and supply channels These substances will be supplied via 3.

Surface contact gripping body The surface contact gripping body 1 is a plate body having a through hole 11, and comes into contact with the flange surface of the upper end of the H-shaped steel that is the non-circular pile B so as to sandwich it therebetween.

Then, by inserting the ball core 12 or the like into the through hole 11 and locking it, the H-shaped steel is grasped.

In addition, although not shown, it is possible to provide a surface other than the flange surface that comes into contact with the web so that the web surface is sandwiched between the two surfaces, and it is also possible to use surface contact grasping so that the web surface is in contact with both the flange surface and the web surface. A body 1 can also be provided.

(c) Joint part The joint part 2 is composed of a base plate 21 to which the surface contact grasping body 1 is attached, and a spacer 23 located between the base plate 21 and the circular pedestal 22, as shown in the example.

[Surface contact gripping body 1 is attached to reinforcing member 1 near both lower ends of board J board 21.]
3, and a spacer 23 is attached to the upper side.

[Spacer 1 The spacer 23 is for securing a space between the circular pedestal 22 and the substrate 21.

A supply pipe 31 of the supply water channel 3 located at the center of the circular frame 22 protrudes into this space, and the protruding supply pipe 31 is connected to a flexible hose 32 .

[Circular mount] The circular mount 22 is a mount for connecting to the rotational drive source A, and has a mounting hole 22a at a position that matches the connection hole C for connection to the rotational drive source A.

Connection with the rotational drive source A can be achieved by aligning the mounting hole 22a and the connection hole C and using, for example, bolts and nuts.

Further, the circular pedestal 22 has a hole in its center, and a supply pipe 31 is located in this hole.

2> Supply water channel The supply water channel 3 is for supplying water etc. to the water pipe, and is formed by, for example, a supply pipe 31 and a flexible hose 32, and the flexible hose 32 is detachably connected to the supply pipe 31. .

The supply pipe 31 is a tube located at the center of the circular pedestal 22, and takes in water etc. supplied from the rotational drive source A when the circular pedestal 22 is attached to the rotational drive source A.

Then, water or the like is supplied from the supply pipe 31 to the water pipe via the flexible hose 32.

In addition, the connection between the flexible hose 31 and the water pipe is as follows.
By being removable, the flexible hose 32 can be recovered after insertion.

Effects of the Present Invention> As explained above, the present invention grasps a non-circular pile body with a surface contact grasping body that makes surface contact with the non-circular pile body, and connects this surface contact grasping body to a rotational drive source. It has a joint part.

Therefore, it has become possible to provide a connection device for a non-circular pile body and a rotational drive source, which is the object of the present invention.

In particular, since the device of the present invention grasps the non-circular pile body in a plane, it is possible to efficiently transmit the rotational force of the rotational drive source to the non-circular pile body.
