Description

[Detailed explanation of the invention] This invention consists of selecting and combining multiple types of flint unit pieces with different lengths one after the other, making the whole a combined frame of the stand, and adjusting the base length by various combinations. Regarding the length and length of flint required for the lumber.

As is well known, at mountain retaining sites, flint is interposed between the strut beams and the retaining materials, and this is used to effectively support the sheet pile.

The applicant has previously proposed a box-shaped flint as an alternative to the traditional V-shaped flint, and has developed a box-shaped flint that strongly counters the full-surface support for the lumber when assembled at the waist. This is because it is easy to attach.

However, the flint used in this case is only a one-box type, and therefore, in order to deal with cases where the earth pressure varies in different places, it is necessary to prepare flint of various sizes with different support lengths for the lumber. Not only that, but it also had problems such as being difficult to handle because it was a single box.

This idea was made from this point of view, and therefore, the feature here is a flint unit whose longitudinal length is gradually increased in order to form the supporting length required for the storage material. The desired number of stages of the pieces are removably connected in such a manner that the bottom sides and the top sides face each other one after the other, so that the whole mold forms a planar shape.

This invention will be explained below based on the illustrated embodiment.

In Figs. 1 to 3, reference numeral 1 denotes sheet piles which are connected by pouring, and a lining material 2 is attached to the inside of the pile.

This holding material 2 is made of H-shaped steel horizontally, and a large number of bolt holes 3 are arranged along the opposite wall thereof.

Reference numeral 4 denotes a strut member, and a flint material 5 according to the present invention is interposed and fixed between the strut member 4 and the retaining member 2.

The flint material 5 in this case is made by preparing two flint unit pieces 6 and 7 and joining them in stages with bolts and nuts 9 to make the whole into a mold shape.

Here, each piece 6.7 is a short piece on the strut material 4 side and a long piece on the material 2 side, and each piece is cut into a tapered shape at 45 degrees on both longitudinal end faces using H-shaped steel as a base material. A reinforcing end plate 10° 10 made of a single plate that closes the entire end surface is fixed to each end by welding, and a reinforcing core plate 11 is provided in the middle in the longitudinal direction to cross within each groove as shown in FIG. .11 are welded in the same way, and reinforcing middle plates 13 and 13 are welded on the other long sides, leaving holes 12 on the groove bottom side as shown in Figure 3.
... are fixed and hollowed out, and the long piece has one more pair of middle plates 13... than the short piece middle plates 13...
... is fixed.

In this way, the drain holes 14 are provided at appropriate locations, and an appropriate number of bolt through holes 3 are provided in each opposing flange.
...is placed in two rows, top and bottom.

In the case of this Fig. 1, the bottom of the short piece 6 and the long piece 7
The upper sides are the same length, and the various pieces of the mold in this relationship are sequentially assembled into bolts, nuts 9, etc.
One flint material 5 is completed by joining with ....

Although this two-tiered flint 5 has a longer base length of the long piece 7, it is shorter than the three-tiered type described later, and is suitable for use in places with strong earth pressure, such as the longitudinal center of the belly storage material 2. It is located near the end of the wall.

On the other hand, if longer flint unit pieces 8 are combined as shown in Figures 4 and 5, a longer supporting length can be provided, so that the flint unit pieces 8 can be placed at the central position to withstand strong earth pressure. Ru.

In the above example, the end face is linear, the end effectively receives the earth pressure, and there is an overall unity. In some cases, it is cut at right angles to form a staircase shape.

In addition, although the basic embodiment of the piece base is H-shaped steel, it goes without saying that this is not limited to this.

Furthermore, although the piece base bodies are of a common cross-sectional size, it is possible, for example, to make the piece base on the side of the strut material 4 a large size and store the piece base on the side of the strut material 2 with a small cross-sectional size.

This idea is as described above, and therefore, by selectively combining multiple types of flint unit pieces with different lengths in stages, the whole is made into a combined mold frame, and by various combinations, The length of the base can be made to the various lengths required for the material, making it easy to cope with the strength of earth pressure by combining several types of common pieces as necessary. Moreover, since it is a piece type, it is easy to handle.

Incidentally, although not shown in the drawings, it is possible to freely combine longer pieces.

In this case, since it becomes long, it may be divided into two in the longitudinal direction.

Furthermore, as shown in FIG. 8, we are also considering a type in which, for example, the pieces 6 and 7 are integrated and a supplementary piece 8 is added thereto.
