[Industrial applications]

 TECHNICAL FIELD The present invention relates to a jig for mounting a corner piece used in a mountain stop construction site, and particularly to a jig which has a simple structure and is easy to use.

[0002] As is well known, depending on the scale of root cutting, it is well known that, in order to prevent the surrounding ground from collapsing, a sheet pile is driven into the pile, and the sheet pile is angry, cut and struck. I try to support it. By the way, at the above-mentioned site, the corner pieces 4 are used to connect the uprights 2 and 3 for supporting the sheet pile 1 at the corners as shown in FIG. As shown in FIG. 5, the corner piece 4 is made of iron and is composed of two pentagonal side plates 5 and 5 with both ends of the right triangle being cut off at the acute angle side. The joint plates 6 and 6 are fixed to the joint plate 6, and a plurality of bolt holes 7 or elongated holes 8 are formed in the joint plates 6 and 6.

As shown in FIG. 4, the corner piece 4 having the above-described structure is fixedly arranged on the lower surface of the upper ridge 2 on the lower surface of the end and on the lower ridge 3 on the upper surface of the end. The bolt hole 7 or the long hole 8 is used to fix the webbing or the joint member fixed to the end surface facing each other with bolts and nuts.

[Problems to be solved by the device]

 By the way, there is a problem that the corner piece is very difficult to mount, especially because the lower surface of the end is the mounting point when the upper piece is raised. In other words, even if the corner piece 4 is hung with a wire and brought to the mounting location, the uprising 2 to be mounted as shown in Fig. 4 becomes an obstacle and the corner piece 4 cannot be placed at the mounting location. . For this reason, in the end, on the site, the worker uses a ladder or the like to reach the attachment point, pushes and moves the corner piece 4 suspended by the wire to the attachment point, and supports it until the attachment is completed, or at worst. In the case of, the worker may carry the corner piece 4 to the mounting location and fix it.

The present invention has been made to eliminate the above-mentioned difficulty of the mounting work. The purpose of the present invention is to quickly and surely place the corner piece at the mounting position and to easily carry out the mounting work. It is to provide a jig that has a simple structure and is practical.

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a jig for mounting a corner piece of the present invention is to fix a pair of plates each having a hypotenuse at the lower end of a columnar base part to face each other, and to fix the lower end part of each plate and Receiving parts for supporting the corner pieces are projected near the upper end of the oblique side, and a suspending member is fixed to the upper end of the base body.

In the jig of the present invention, the receiving portion on either side is selected depending on the mounting location, the corner piece is placed on the receiving portion, and the plate and the corner piece are easily separated at a plurality of locations. It is held integrally with a clamp member, hung with a wire etc. using a suspending member and placed at the mounting position, and the corner piece and the uprising are fixed with bolts and nuts. Loosen the member and remove the jig from the corner piece.

【Example】

 The present invention will be described in detail with reference to the illustrated embodiments. FIG. 1 is a perspective view showing an embodiment of the present invention. In the figure, reference numeral 10 is a corner piece mounting jig, which includes a columnar base portion 11, a pair of plates 12 and 12, receiving portions 13 and 14, and a hanging portion. The member 15 is a main constituent member.

The columnar base 11 is made of H-shaped steel, and square fixing members 16 are fixed to the lower ends of both flanges 11a and 11a by welding or countersunk bolts, and a right-angled triangle is formed outside the fixing members 16. The pentagonal plates 12, 12 with the sharp corners cut off are fixed by welding or countersunk bolts with the sides 12a, 12a facing downward. Further, a steel L-shaped receiving portion 13 is fixed to the lower ends of the plates 12 and 12 such that a flat surface 13 a thereof projects from the plate 12. Further, an L-shaped receiving portion 14 is also fixed to the upper side of the oblique side 12a of each plate 12 so that the flat surface 14a projects from the plate 12, and the corner piece is provided on each of the receiving portions 13 and 14. The end is placed.

A suspending member 15 is attached to the upper end of the columnar base portion 11. The member 15 is composed of an H-shaped steel beam 16 laterally fixed to the upper end of the base 11, and a pair of suspension plates 17 and 17 standing on the upper surface of the beam 16. The mounting position of the suspension plates 17, 17 is fixed by placing a corner piece on each of the receiving portions 13, 14 arranged on the left and right, and when suspending the corner piece, the position of the center of gravity is obtained. The plate also has a through hole 18 through which a suspending wire is passed. 1 to 3, reference numerals 19 and 20 are reinforcing ribs for connecting the beam 16 or the beam 16 and the base portion 11.

Explaining how to use the corner piece mounting jig 10 having the above-described structure, first, after confirming the situation in the field and the mounting position, one of the left and right plates 12, 12 provided on the jig 10 is checked. Decide which to use. As shown in FIGS. 2 and 3, the lower end surface of the corner piece 4 is supported by the receiving portion 13 and the hypotenuse part is supported by the receiving portion 14, and one side plate 5 of the corner piece 4 is attached to the plate 12 as well. After that, the side plates 5 of the piece 4 and the plate 12 of the jig 10 are clamped and fixed using a plurality of C-shaped clamps 21 (FIGS. 1 and 3). After that, the wire 22 is hung on the through hole 18 of the predetermined hanging plate 17 and is hung to the vicinity of the mounting position of the corner piece 4 by using a crane or the like. When the jig 10 reaches the vicinity of the mounting position, the flange 11a on the side that holds the corner piece of the columnar base 11 is moved by the operation of the crane or human power so that the flange 11a is moved up to contact the corner 2 and the corner is moved. When the piece 4 is raised and positioned on the lower surface of 2, and the jig 10 is lifted again by the crane, the corner piece 4 is raised and contacts the lower surface of the 2, that is, the web surface (FIG. 2). In this state, accurate positioning is performed, and the through hole and the long hole provided in the corner piece 4 are used to raise the bolt B and the nut N, and tighten and fix them to 2. When the mounting is completed, the clamp 21 is removed, the jig 10 and the corner piece 4 are disengaged, and the jig 10 is moved to a predetermined position by a crane.

It is needless to say that the present invention is not limited to the above-described embodiment, and various modifications and design changes can be made without departing from the spirit of the invention.
