DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an H-shaped steel driving device for earth retaining.

[0002]

2. Description of the Related Art To perform earth retaining in foundation work of a building, an auger for excavating a vertical hole, a pile driver for driving an H-shaped steel into the hole, and a backhoe for further shaving the earth are usually used. Requires three types of machines.

[0003] Further, in recent years, a part of the Building Standard Law has been eased, and it has become easy to construct a basement.

[0004] This basement is made because the site is so small that it has to be used up to the basement. However, in the case of a general house, the site is narrow and the road in contact with the site is also very narrow. Is the actual situation.

[0005] Further, when the basement is to be made, earth retaining must be performed as described above, but this operation requires three types of conventional auger, pile driver and backhoe as described above.

[0006]

However, since the auger and the pile driver are generally large in size, they can hardly be used in a general house under the above-mentioned circumstances.

[0007] Further, the pile driving machine generates a great deal of vibration and noise when driving a pile, and may cause trouble when the distance between the neighboring house is small as in a general house.

[0008] The present invention has been made in view of the above points, and in the case where earth retaining is performed in a situation where the land is narrow and the road in contact with the land is narrow as in a general house,
An H-shaped steel for retaining can be driven without using an auger and a pile driver as in the past, and can be performed with almost no vibration and no noise.
It is intended to provide a steel shape driving device.

[0009]

SUMMARY OF THE INVENTION Accordingly, the gist of the present invention is to provide a retaining H-shaped steel, a metal frame member detachably connected to an upper end of the retaining H-shaped steel, A buried body made of a steel plate having a V-shaped lower end connected to the lower ends of both flanges of the H-section steel and connected along the flanges, and a circumference of the web of the H-section steel, the length of the web being Attached so as to rotate along the direction, rotate with the required drive source, and attach a shovel-shaped excavated body standing up to the outside of the flange at the required interval,
An earth endless movable body which is partially detachable and can be detached after driving an H-shaped steel, and a clamp device which can be connected to the tip of a boom of a backhoe and can be freely opened and closed, which grips the H-shaped steel. H-shape driving device for fastening.

Further, a chain or a belt may be used as the endless moving body. In this case, while a driving chain wheel or a driving roller for rotating by a required driving source is disposed in the metal frame-shaped body, a driven chain wheel or a driven roller is disposed between the buried bodies, and these driving chain wheels are disposed. Alternatively, the chain or belt is entangled over the driving roller and the driven chain wheel or the driven roller.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of an embodiment of the present invention in which an H-shaped steel for retaining is partially omitted, FIG. 2 is a perspective view in which a metal frame is partially cut away, and FIG. FIG. 4 is a partial side view of an H-shaped steel for retaining and a chain, FIG. 5 is a partially enlarged perspective view of the chain, FIG. 6 is an enlarged perspective view of a clamp device, and FIG. It is an operation explanatory view.

In the drawing, reference numeral 1 denotes an H-shaped steel for earth retaining. Reference numeral 2 denotes a metal frame that is detachably connected to the upper end of the retaining H-beam 1. In the present embodiment, the metal frame 2 is fixed by bolts 2a, 2a so that the metal frame 2 can be removed after driving the H-shaped steel 1 for earth retaining. Note that an appropriate fastening means may be used.

Reference numeral 3 denotes a drive chain wheel disposed in the metal frame 2. The drive chain wheel 3 is fixed to a rotating shaft 5 that is rotated by the power of a motor 4 as a drive source. In this embodiment, a motor is used as a drive source, but other appropriate means can be adopted.

6, 6 are both flanges 1a of the H-section steel 1;
An embedded body connected to the lower end of 1a along the flanges 1a, 1a, and the lower end is formed in a V-shape to facilitate driving.

Reference numeral 7 denotes a driven chain wheel disposed between the buried bodies 6 and 6. The driven chain wheel 7 is rotatably supported on a shaft 8.

Reference numeral 9 denotes an endless chain which is wrapped around the driving chain wheel 3 and the driven chain wheel 7. The chain 9 extends around the web 1b of the H-shaped steel 1 along the length direction of the web 1b. It is attached to rotate.

Excavators 10, 10, 10,... Standing up to the outside of the flanges 1a, 1a of the H-section steel 1 at required intervals are attached to the chain 9. The shovel-shaped excavated bodies 10, 10, 10... Are used for shaving soil, carrying the ground to the ground, and drilling holes. The shape is not limited to the illustrated one.

The chain 9 is partly detachable so that it can be removed after the H-shaped steel 1 has been driven. That is, the chain 9 can be used repeatedly, for example, as shown in FIG.
The bolts 11 and 11 are connected to each other. When the driving of the H-section steel 1 is completed, the bolts 11 and 11 are pulled out and removed from the H-section steel 1 together with the metal frame 2.

Reference numeral 12 denotes an openable / closable clamp device for gripping the H-shaped steel member 1, which can be connected to the tip of a boom of a backhoe. The clamp device 12 has grippers 14 and 14 pivotally attached to the left and right sides of a base 13 so as to be openable and closable, and is driven to open and close by hydraulic cylinders 15 and 16. In addition, the base portion 13 is provided with connecting portions 17 and 18 for connecting to the tip of the boom of the backhoe.

Reference numeral 19 denotes a backhoe, which removes a bucket (not shown) which is usually attached, and attaches the clamp device 12 to the tip of the boom 19a instead. The backhoe is smaller than an auger or pile driver, so it can be used on narrow sites and roads.

Next, the operation of the present embodiment will be described. The motor 4 is operated with the H-section steel 1 standing upright at the location to be driven. Thus, the chain 9 is made of the web 1b of the H-section steel 1.
Rotate vertically along. When the chain 9 rotates, the shovel-shaped excavated bodies 10, 10, 10 attached to the chain 9
... cuts down the bottom of the H-section steel 1 and digs it down. In addition, the shaved soil will be transported to the ground one after another.

At the same time, the H-shaped steel 1 is pushed down by the backhoe 19 via the clamp device 12. And
When the H-section steel 1 is pushed in and sinks to some extent, the clamp device 12 is opened again, shifted onto the H-section steel 1 and gripped again. Then press again. By repeating this, the H-section steel 1 is driven. When the driving is completed, the chain 9 and the metal frame 2 are removed, and cement milk or the like is poured between the flanges of the H-shaped steel 1.

Although the above embodiment uses a chain, a belt may be used instead of the chain. In the case of a belt, a roller is used instead of the chain wheel. Although not shown, other members may be used instead of the chain and the belt.

[0024]

As described above, the present invention has the above-described configuration and operation. Therefore, as long as there is a space for a backhoe, even if it is a narrow land or a road where an auger or a pile driver cannot enter, the soil retaining H can be used.
It can drive shaped steel.

Further, since a vertical hole is drilled by a shovel-shaped excavated body and press-fitted by a backhoe, a two-stage process of drilling with an auger and pushing with a pile driver as in the related art is not required. That is, workability is greatly improved since only one process is required. Also, since these two types of machines are not required, the cost is reduced.

Further, since the hole is pressed down by the backhoe while digging the hole, vibration and noise unlike the conventional pile driver are not generated. Therefore, it is effective when the problem with the neighbor is narrow as in a general house.
