Description

[Detailed Description of the Invention] The present invention relates to a jig for erecting a sheet pile, which is a U-shaped steel sheet pile.

Sheet piles come in various shapes, but
Usually, as shown in FIG. 1, sheet piles 1, 1', etc., which are approximately U-shaped with a flat surface 1a in the center and have joints 1b bent at both ends, are often used.

In this sheet pile, the first sheet pile 1 is driven into the ground first, the joints 1b are connected correspondingly, and the second sheet pile 1' is then driven in succession. When the second sheet pile 1' rotates in the direction of the arrow about the joint 1b of the first sheet pile 1, there is a risk that the entire structure will be bent and connected.

An object of the present invention is to prevent such inconveniences and to provide a simple and inexpensive jig that can precisely build sheet piles on desired lines.

However, according to the present invention, the purpose of the lever is to consist of a rectangular box-like hardware with an L-shape in plan, which is attached by a hook parallel to two parallel guide rails facing each other. A jig is constructed by providing a convex portion that protrudes beyond the contact portion of the central plane of the first sheet pile and a contact portion of the joint of the second sheet pile connected to the first sheet pile. This is achieved by configuring.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a plan view showing an embodiment of the jig of the present invention, in which reference numerals 2 and 2' indicate two parallel guide rails. In this embodiment, the guide rails 2, 2' are made of H-shaped steel with the flange end 3 facing upward, and both ends of the rails 2, 2' are connected with another H-shaped steel 4 to form a rectangular frame as a whole. Formed as a body.

Reference numeral 5 in the figure indicates a metal fitting to be attached to the guide rails 2, 2', and its details are shown in Figs.
A forward convex portion 5c is provided on one side of the rectangular box body 5b to which a and 5a' are attached, so that the entire body has an L-shape in plan view,
Two vertically parallel protrusions 5d and 5d' are formed on the front end side surface of the convex portion 5c.

Furthermore, hole flanges 5e and 5e' for hanging are provided protruding from the upper surface of the box body 5b.

In this way, the hardware 5 has a contact part A of the flat surface 1a of the sheet pile on the front surface of the rectangular box body 5b, and a contact part of the joint 1b of the sheet pile between the protrusions 5d and 5d' on the front surface of the convex part 5c. B.

Next, how to use it will be explained.

For example, a columnar pile 6, in which sheet piles 1, 1'... are buried in the center with mortar or soil concrete,
6', etc., first set the guide rails 2, 2' at the planned construction positions of the piles.

Next, the flange ends 3 are inserted into the hooks 5a, 5a', and the hardware 5 is attached to the guide rails 2, 2' so as to be horizontally movable and facing each other.

first. The flat surface 1a of the first sheet pile 1 that has already been built is placed against the contact portion A of the hardware 5 on the guide rail 2 side.

Next, the flat part 1a of the second sheet pile 1' is
Place it on the contact part A of the hardware 5 on the guide rail 2' side,
The joint 1b of the sheet pile 1' is connected to the guide rail 2.
1' is spliced onto the sheet pile 1 so that it touches the abutting part B of the side hardware 5.

As a result, the pile 1' is driven in a completely symmetrical position with respect to the pile 1, and by repeating the above operation by sequentially moving the two hardware 5 little by little laterally along the guide rails 2 and 2'. , sheet piles 1, 1'... can be built in a straight line with high precision.

Note that if the guide rails 2, 2' are curved in a large arc shape, and the back surface of the hardware 5 is also curved to match this curvature, the sheet piles 1, 1'... can be built in an arc shape. This will be the jig used during the process.

Further, although the above embodiment shows a case in which H-shaped steel is used as the guide rails 2, 2', the invention is not necessarily limited to this, and grooved rails and wheels or sleds provided on the hardware 5 side may be used. Combinations of the above and various other application examples are conceivable.

As described above, the sheet pile erection jig of the present invention consists of metal fittings that are attached to two parallel guide rails facing each other. Since a contact part and a contact part of the joint of the second sheet pile connected to this first sheet pile are provided, it is possible to build a sheet pile with a simple and inexpensive structure, easy to use, and with high precision. can be done quickly. Furthermore, since the member that holds the flat part of the sheet pile and the joint are integrated, the positional relationship between the respective abutting parts is defined, making it easier to set the sheet pile and positioning the sheet pile in the correct position. It can be set reliably.
