Description

[Detailed description of the device] << Industrial application field >> This device is used to hold the soil with a sheet pile to prevent the surrounding ground from collapsing during excavation. The present invention relates to a gap retainer in which a portion is formed and cement is poured into the storage portion so that the sheet pile does not incline due to earth pressure.

《Prior art》 Conventionally, when building a building, the ground is dug down over a wide area in order to provide a basement, but when excavating, the soil is held down with sheet piles so that the surrounding ground does not collapse,
When earth pressure is large, it is known to interpose a lump of concrete in a plate material or a vinyl bag between the abdomen and the sheet pile to prevent the sheet pile from tilting.

<Problems to be solved by the invention> By the way, in the above-mentioned conventional ones, the plate material interposed between the sheet pile and the abdomen and the lump of concrete put in the vinyl bag are troublesome to install, and due to changes in earth pressure. However, there are many drawbacks, such as the fact that the gap cannot be safely filled for a long period of time.

This invention solves the above-mentioned problems and aims to obtain a gap holder extremely convenient for use.

<< Means for Solving Problems >> The gap retainer of the present invention for achieving the above object is
The back plate 1 and the front plate 2 made of a tin plate are bent in opposite directions from the lower edge and both side edges of the back plate 1 and the lower back bending piece 3, the lower front bending piece 4 and the both back side bending pieces 5, respectively. 5 and the front both-side bent pieces 6, 6 are provided, and mounting pieces 8, 8 protruding upward and having nail insertion holes 7 are attached to the rear plate 1, and are bent outwardly above the front plate 2. And a locking bent piece 10 having an inverted U-shaped first locking groove 9 is provided. Further, a rectangular plate 11 made of a tin plate is used as the rectangular plate 11 with both longitudinal edges 12 and 12 on the back surface. Bottom plate 1 placed on lower bent piece 3 and front lower bent piece 4
3, both sides of the bottom plate 13 and longitudinal side edges 12 and 12 via center fold lines 14 and 14 attached to the back side bent pieces 5 and 5 and the front side bent pieces 6 and 6, respectively. Second locking grooves 18, 18 for locking the upper end portions 17, 17, 17, 17 of the rear side bent pieces 5, 5 and the front side bent pieces 6, 6 via 15 and the outward folding lines 16, 16. The coating pieces 19 provided with are formed.

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 is a back plate, which is made by bending a back plate 1 and a front plate 2 made of a tin plate in opposite directions from the lower edge and both side edges. The lower back bent piece 3, the lower front bent piece 4, the back side bent pieces 5, 5 and the front both side bent pieces 6, 6 are provided, and the back plate 1 is projected upward and a nail insertion hole 7 is formed. The mounting pieces 8 and 8 are attached, and a locking bent piece 10 is provided above the front plate 2 and is bent outward to form a reverse U-shaped first locking groove 9, and a tin plate is further provided. A rectangular plate 11 is used as a material, and the rectangular plate 11 has both longitudinal edges 1
2, 12 are bottom plates 13 placed on the lower back bent piece 3 and the lower front bent piece 4, and center folding lines 14, 1 on both sides of the bottom board 13.
Both side plates 1 with both longitudinal edges 12, 12 attached to the back side bent pieces 5, 5 and the front side bent pieces 6, 6 via
5, 15 and the outer fold lines 16, 16 through the upper and lower end portions 17, 17, 1 of the rear side bent pieces 5, 5 and the front side bent pieces 6, 6, respectively.
The covering pieces 19 and 19 provided with the second locking grooves 18 and 18 for locking 7 and 17 are formed, and 20 is the ground, and 21 is a sheet pile and the surrounding ground 20 is used when excavating. It is to prevent it from collapsing. Reference numeral 22 is an abdomen raised by an H-shaped steel material. Reference numeral 23 denotes a shaft supporting portion of the mounting piece 8 attached to the back plate 1, and the mounting piece 8 rotates about the shaft supporting portion 23, and when the nail 24 is driven through the nail inserting hole 7, the nail inserting hole for the sheet pile 21 is inserted. The position of 7 is changed. That is, the sheet pile 21, which has been used several times, may have many nail holes and may not be able to drive the nail 24 strongly. Therefore, by simply changing the position of the nail insertion hole 7, the nail 24 can be firmly driven into the sheet pile 21. Reference numeral 25 is a cement, and 26 is a storage portion for the cement.

Further, the size of the gap 27 formed between the sheet piles 2, 2 ... Provided in parallel with a large number of plates and the bellows raising 22 is not necessarily constant as shown in FIG. Therefore, the width of the rectangular plate 11 formed of a tin plate is used as the fourth width in the field.
As shown in the drawing, the accommodating portion 26 is formed by being cut by scissors and supported by the gap 27.

<Advantages and effects of the invention> The invention has the above-described configuration, and is made by using the tin plate as a material, and bending the back plate 1 and the front plate 2 from the lower edge and the both side edges in opposite directions to form a lower back bent piece. 3 and front lower bent piece 4, both rear side bent pieces 5 and 5, and front both side bent pieces 6 and 6, and mounting pieces 8 and 8 projecting upward and forming nail insertion holes 7 on the rear plate 1. Is attached to the front plate 2 and is bent outwardly to form an inverted U-shaped first locking groove 9, and a locking bent piece 10 is provided.
Since the back plate 1 of the sheet pile 2 is first attached by providing the above, the back plate 1 can be attached by driving the nail 24 into the sheet pile 2 through the nail insertion hole 7 or if the sheet pile 2 is made of metal. The mounting pieces 8 and 8 are brazed to attach the back plate 1 to the sheet pile 2.

Next, the first U-shaped locking groove of the locking bent piece 10 provided above the front plate 2 in the bellows riser 22 formed of H-shaped steel corresponding to the back plate 1 attached to the sheet pile 2. The front plate 2 is attached to the abdomen 22 by hooking 9 on it. Therefore, the rectangular plate 11 is attached to form the storage portion 26 into which the cement 25 is poured. The rectangular plate 11 is made of a tin plate, and the rectangular plate 11 has both longitudinal edges 1
2, 12 are bottom plates 13 placed on the lower back bent piece 3 and the lower front bent piece 4, and center folding lines 14, 1 on both sides of the bottom board 13.
Both side plates 1 with both longitudinal edges 12, 12 attached to the back side bent pieces 5, 5 and the front side bent pieces 6, 6 via
5, 15 and the outer fold lines 16, 16 through the upper and lower end portions 17, 17, 1 of the rear side bent pieces 5, 5 and the front side bent pieces 6, 6, respectively.
Due to the formation of the covering pieces 19, 19 provided with the second locking grooves 18, 18 for locking 7, 7, the mounting is extremely simple and can be carried out as shown in FIG. is there.

When the size of the gap between the sheet pile 21 and the bellows 22 does not match the width a of the rectangular plate 11, the sheet is cut through the scissors for cutting the flexible board, and the sheet pile 21 and the bellows 22 are cut as shown in FIG.
The width a of the rectangular plate 11 matching the size of the space between the rectangular plates 11 can be easily obtained, and the storage portion 26 can be formed very easily. Then, the cement 25 is poured into the storage portion 26 and solidified, so that the sheet pile 2
The present invention has many practical effects such as safe movement of the ground 20 by preventing the movement of the gap between 1 and the abdomen 22.
