Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for construction of a partition wall, an edge wall, or a sleeve portion (hereinafter abbreviated as "partition wall", etc.) to be arranged in slope earthwork using a stacking block or a tension block. The present invention relates to a block for a partition wall and a method of constructing a partition wall using the block.

[0002]

BACKGROUND OF THE INVENTION As shown in FIG. 5, a sloped earthwork using flat piles 50 or valley piles 51, or tension blocks (hereinafter abbreviated as "pile blocks etc. 52"), Construction of the bulkhead 53 was obligatory at regular intervals of construction extension. The partition wall 53 is arranged so that the stacking block or the like 52 extending in the construction extension direction is cut off here, and the slope block defect such as the collapse of the stacking block or the like 52 is prevented only within the section.

Further, at the end of the construction extension, an edge wall 54 is constructed and formed for a stable finish. Further, the stairs 56 arranged at appropriate positions on the slope have sleeve portions 57 formed on both sides thereof.

[0004]

2. Description of the Related Art Conventionally, the partition wall 53 and the like have been formed on site by assembling a formwork (not shown) up to the entire height of the slope 55 and pouring fresh concrete into the formwork.

[0005]

However, the on-site construction of such a partition wall 53 has the following problems.

Since there is a mold dismantling after curing and curing, it is necessary to pre-form the partition walls and the like before construction of the stacking blocks and the like, and the completed dimension is usually several tens of centimeters wide and the height is several meters. Since the partition wall 53 is held upright, it is necessary to install a support or the like, and this support work is very difficult and dangerous, and it is difficult to correct.

[0007] Since the ready-mixed concrete for partition walls is directly placed on the ground (“cut slope”), it is necessary to finish the ground smoothly, which makes earthwork difficult. In addition, when the earthwork is rough, the formwork must be assembled according to this, and the formwork is very complicated.

[0008] Since on-site formation requires various processes such as formwork, concrete pouring, curing, demolding, and supporting work, the construction period required a long period (about one week).

Further, since the inside of the formwork assembled up to the slope height at once has a so-called forward rolling structure (having a slope toward the front) along the slope, fresh concrete is added from the upper part of the formwork. When injected, the mixed aggregate may be cured in a biased state, and there is a problem in strength after completion.

Further, after the completion of the stacking work of the stacking blocks and the like, the front surface of the partition wall was separated from the others, and it was unbalanced in view. As a modification, the surface could not be finished with mortar or the like.

[0011]

[Purpose] Therefore, the present invention has been made by paying attention to the above-mentioned problems, and the purpose thereof is to form a block of a predetermined shape in advance from precast concrete, and stack the blocks on site to safely and efficiently partition a partition wall in a short construction period It is intended to provide a partition block for constructing the above and the like, and a construction method of the partition using the block.

[0012]

In order to achieve the above object, a partition block of the present invention comprises a front plate having a rectangular front surface and both side plates formed so as to extend rearward from both side edges of the front plate. And are mainly formed by concrete molding.

Further, the side plates facing each other may be connected by a connecting means, and further, the front plate, the side plate and / or the connecting means may be respectively assembled. The method of constructing a partition wall, a small wall, or a sleeve portion using such a partition block is to stack and connect the partition block one by one or a plurality of blocks, and pour in concrete into the internal space. Build by integrating them.
