Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a hitting material in a temporary construction work for earth retaining and its apparatus.

[0002]

2. Description of the Related Art Conventionally, when a hitting material is provided at a corner where an earth rising bulge and a girder intersect, the length of the hitting material made of H-shaped steel,
Precision is required for positioning of the rising portion and the connection part with the cutting beam by the H-shaped steel, and at the connection portion, both end receiving fittings of the fired material are welded to the uprising and cutting beam side, and Since both ends were connected by welding or bolts, the connection was not easy and a lot of labor was required for separation work after use.

[0003]

The present invention does not require precision in the length dimension of the fired material, and the position of the connecting portion can be freely set according to the length of the fired material, and is easy to disassemble after use. It is also an object of the present invention to provide a hot-melting material construction method and an apparatus therefor which can be easily reused without damaging a welding material, a bolt hole or the like on the hot-melting material, the uprising or the cutting beam.

[0004]

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention is a temporary earth retaining construction in which a flint material obliquely intersecting the uprising and the crossbeam is interposed between the uprising and the crossbeam. A clamping bolt in which the end plate of the fired material is screwed into the end of the bifurcated metal fitting.
Preparative the result was clamping support, placing the end lower surface of the angle brace member onto a receiving plate, in contact with the end face of the angle brace member to the side of an upright cylinder provided on the receiving plate, receiving plate and該火hitting member Is clamped and supported by the bolts , and the uprising and the girders are connected by the firing material.

An upright cylinder is provided on the end plate of the punching material, and a holding plate for the end of the punching material is provided on the upper surface of a small-diameter cylinder fitted in the cylinder. The receiving plate and the holding plate are provided inside the upright cylinder and the small-diameter cylinder. Tighten with bolts and nuts that are inserted into the upright plate, and attach the upright plate provided on the receiving plate and the flange of H-shaped steel to the forked metal fitting.
Constituted by angle brace member construction equipment screwing the bolt to the end result of the earth retaining a temporary machining which is formed by forming so as to clamp the.

[0006]

According to the present invention disposed HaraOkoshi 1 by H-beams 9 in the horizontal direction (YokoMuko) in contact with the outer surface of the earth retaining a sheet pile,該腹Okoshi 1
Is supported by a cross beam 2 made of H-shaped steel 9 arranged in the horizontal direction (longitudinal direction), and temporary work for earth retention is performed. The corners of the earth retaining a sheet pile is supported by HaraOkoshi 1,1 to each other perpendicular.
The fired material 3 is made of H-shaped steel 9 having a predetermined length and is obliquely arranged by a crane between the uprising 1 and the girder 2, and the fired material end receiving plates 4 and 4 are arranged at both ends. Upright plate 13,13
Is in contact with the uprising 1 and the girder 2 made of H-shaped steel 2
The receiving plates 4, 4 are fixed by sandwiching and supporting the corresponding plates 13, 13 and the flanges 9 ', 9'of the uprising 1 and the truss 2 with a bolt 6 screwed into the end of the receiving plate 4 4, both ends of the fired material 3 are placed and both end surfaces 3 ′, 3 ′ are brought into contact with the upright cylinders 8, 8 and then a small diameter cylinder 8 ′ is fitted into the cylinder 8 to secure the bolt 11, The nut 12 clamps and clamps the end of the fired material 3 between the receiving plate 4 and the pressing plate 10, and the lower plate 9'of the receiving plate 4 and the H-shaped steel 9 and the pressing plate 10 and the upper flange. 9'is supported by sandwiching the annular blades 7 and 7 against each other.
Can hold the uprising 1, the cutting beam 2 and the fluttering material 3 in a truss shape in the same plane through the fluttering material 3 and the upright cylinders 8, 8 at both ends thereof.

The length of the hitting material 3 is appropriately determined, and the positions of the upright cylinders 8, 8 can be appropriately determined on the uprising 1 and the truss 2 according to the length. The load of the hitting material 3 is the above-mentioned receiving plate 4,
Both ends are supported by 4, and the compressive load can be supported in the direction of the center line of the hitting material 3 via the upright cylinders 8, 8. Further, the pressing plates 10 and 10 can suppress the levitation at both ends due to an unbalanced load.

After completion of the construction, the hammering material 3 is supported by a crane, and the annular blades 7, 7 facing each other are separated from each other to separate the hammering material 3 from the receiving plate 4 and the holding plate 10, and the receiving plate 4 Is separated from the uprising 1 and the truss 2.

[0009]

EXAMPLE A fired material 3 having a predetermined length is formed from an H-shaped steel 9 and an upright plate 13 is provided on an end receiving plate 4 of the fired material 3. flange 9 of Setsuhari 2 ', 9' abuts on an annular edge 7 and the opposing edge 7 formed on the end face of the forked bracket clamping bolt 6 which is screwed to an end portion 5 'of the 5
The receiving plate 4, 4 attached to the HaraOkoshi 1 and Setsuhari 2 by clamping supporting the wear plate 13 and the flange 9 'between.

An upright cylinder 8 is welded and fixed to the receiving plates 4 and 4, and a small diameter cylinder 8'is fitted into the cylinder 8 from above, and a hitting material end holding plate 10 is attached to the upper surface of the small diameter cylinder 8 '. Are fixed by welding, and the holding plate 10 and the receiving plate 4 are fixed to the both cylinders 8 and 8 '.
It is tightened by a tightening bolt 11 and a nut 12 which are inserted inside. Then, the end of the fired material 3 made of H-shaped steel 9 is sandwiched between the receiving plate 4 and the holding plate 10, and the end face 3 ′ is in contact with the side surface of the upright cylinder 8, and in that state, the upper and lower flanges 9 of the fired material 3 are held. ', 9' and the receiving plate 4 and the pressing plate 10 are clamped and supported by the opposed annular blades 7, 7 to connect the uprising 1, the cutting beam 2 and the striking material 3 via the upright cylinders 8, 8. Form a truss. In the corner portion, the truss is formed by interposing the hammering material 3 between the uprisings 1 and 1 orthogonal to each other instead of the trusses 2 as described above.

Reference numeral 14 in the drawing denotes a mounting bolt provided on the pressing plate 10.

[0012]

Since the present invention is based on the method and apparatus described above, the hitting material 3 is formed of H-shaped steel 9 or the like, and can be easily interposed between the uprising 1 and the girder 2 regardless of the length. Thus, there is an effect that a truss can be formed, and that there is no damage due to welding or bolt holes, and that disassembly and assembly can be easily performed.
