JPH0336319A - Method of construction for piling styrene foam block - Google Patents

Abstract

PURPOSE:To construct stable banking by performing construction in such a way as forming irregularity in surfaces of a styrene foam block and successively piling it, while the block is combined with each other, then coating a total unit with earth and sand. CONSTITUTION:An irregularity part is formed in upper, bottom and peripheral wall surfaces of a rectangular styrene foam block 1. Next, this block 1 is arranged in good order on the ground and wide laid in equal height. Now, the block 1 is arranged in a manner wherein its irregularity part is engaged with each other. Next, on the upper surface of a group of the laid blocks 1, they are piled layer by layer while the irregularity part of the block 1 is meshed. The upper and periphery of the uppermost layer are coated with earth and sand, and banking is completed. In this way, the blocks are possible to sufficiently resist against force acting in a horizontal direction further with prompt execution possible.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a construction method in which styrofoam blocks are piled up and used as embankment.

<Conventional technology> There is a method of constructing an embankment by stacking Styrofoam blocks to create the original shape of the embankment, and covering the top and surrounding area with earth and sand.

In this method, rectangular polystyrene foam blocks measuring, for example, about 180 x 90 x 40 cm are stacked one after another, and the blocks are engaged and integrated by interposing nails or metal fittings with protruding blades between the blocks.

<Problems to be solved by the present invention> Such conventional embankment construction methods had the following problems.

(a) All the stacking of Styrofoam blocks had to be done manually, making it difficult to mechanize and resulting in poor construction efficiency.

Because a simple joining method of interposing metal fittings between the blocks was used, the resistance to horizontal forces was low, making the building unstable during an earthquake and potentially causing it to collapse.

<Objective of the present invention> The present invention was made in order to improve the above-mentioned problems, and the purpose of the present invention is to provide a Styrofoam piling method that can sufficiently resist forces acting in the horizontal direction and construct a stable embankment. shall be.

<Means for Solving the Problems> In other words, the present invention is a method of constructing an embankment by piling up Styrofoam blocks. This is a method of stacking Styrofoam blocks, which is characterized by stacking them up and covering the entire structure with earth and sand.

<Description of the present invention> The present invention will be explained in detail below.

<A> Styrofoam block The Styrofoam block 1 used in this construction method is formed from Styrofoam into a rectangular shape.

However, a large number of concave portions and convex portions are formed around it.

The uneven portions are formed by arranging the plurality of blocks 1 at positions where they interlock with each other.

That is, uneven portions are formed on the top surface, bottom surface, and surrounding wall surfaces.

However, it is not always necessary to form the uneven portions on the entire circumference of the six sides of the rectangular parallelepiped.

In some cases, unevenness may be formed only on the top and bottom surfaces, thereby preventing relative movement of the upper and lower layers.

By forming uneven portions on the surrounding wall surface, it is possible to further prevent blocks from moving within the same layer.

<Enterprise> Construction method: Lay the Styrofoam blocks 1 described above in an orderly manner on the ground at the same height.

At this time, if irregularities are formed on the wall surface of the block 1, the blocks 1 are arranged at positions where the irregularities engage with each other.

In this way, the adjacent blocks 1 are tightly connected to each other and their mutual positions are restricted.

(kuha) Laying of the upper layer Once the laying of the first layer of block groups is completed, the upper layer of the first group of blocks is laid on top of it.

Since the top and bottom surfaces of the block 1 are formed with projections and recesses at positions where they engage with each other, as the blocks are laid down, the upper and lower projections and recesses successively mesh closely and engage with each other.

<2> Completion of the embankment In this way, blocks 1 are piled up layer by layer, earth and sand is covered on and around the top layer, and the embankment is completed.

Effects of the present invention> Since the present invention is implemented in the above order, the following effects can be achieved.

〉I formed an uneven part around the styrofoam block.

Therefore, it acts as a unit against horizontal forces such as earthquake forces, and does not break apart.

Because the interlock between the blocks is strong, it can be applied not only to construction on flat surfaces but also to embankments on slopes.

<C> There is no need for the metal fittings for joining that are interposed between the conventional styrofoam blocks, so there is no need to arrange or install them, and construction can be carried out quickly.

(2) The mutual positional relationship between the styrofoam blocks is regulated and determined by the arrangement of the uneven portions.

Therefore, the shape of the entire embankment can be formed accurately.
