Description

Description: TECHNICAL FIELD The present invention relates to a method of stacking styrofoam blocks and using them as embankments, and more particularly to a method of firmly restraining the blocks. Things.

<Conventional technology> There is a construction method in which an original form of an embankment is formed by stacking Styrofoam blocks, and the upper surface and surroundings are covered with earth and sand to construct an embankment.

In this method, rectangular Styrofoam blocks of, for example, about 180 × 90 × 40 cm are stacked in order, and the blocks are engaged with each other by interposing a metal fitting with a nail or a protruding blade so as to be integrated.

<Problems to be Solved by the Present Invention> Such a conventional embankment method has the following problems.

<A> Since a simple joining method is adopted, in which metal fittings are interposed between the blocks, the resistance to horizontal forces is small, and there is a risk of becoming unstable during an earthquake and causing collapse.

<B> Since the inside of the embankment is composed of a stack of Styrofoam blocks, the water permeability inside is poor and good drainage cannot be performed.

<Object of the present invention> The present invention has been made in order to improve the above-mentioned problems, and is capable of sufficiently resisting external force in the horizontal direction, improving drainage inside the embankment, and constructing a stable polystyrene foaming method. The purpose is to provide.

<Means for Solving the Problems> That is, the present invention relates to a method for stacking styrofoam blocks, in which blocks of styrofoam laid horizontally adjacent to each other are stacked hierarchically and the periphery of the blocks is covered with earth and sand. A styrofoam block characterized in that each block is constrained and laid with the plurality of nonwoven fabrics while the adjacent blocks are sewn in a phased manner with a plurality of continuous band-shaped nonwoven fabrics.

<Description of the Present Invention> Hereinafter, the present invention will be described in detail.

<A> Styrofoam block The styrofoam block 1 used in the present method is a styrene foam formed in a rectangular shape.

Its dimensions are, for example, 180 × 90 × 40c, as described above.
Use something about m.

<B> Non-woven fabric band In order to mutually restrain the Styrofoam blocks 1,
The nonwoven band 2 is used.

The nonwoven fabric band 2 is formed by forming a known nonwoven fabric into a belt-like shape.

As the characteristics of the nonwoven fabric band 2, a material having a sufficiently large tensile strength is used.

The nonwoven fabric band 2 allows water to freely pass through due to the properties of the material.

<B> Construction method The styrofoam blocks 1 are arranged neatly on the ground G and widely laid at the same height.

Then, a plurality of nonwoven fabric bands 2 are sequentially interposed between the adjacent blocks 1 in a phased manner, and the entire block 1 group is restrained by the nonwoven fabric band 2, and the block 1 group acts integrally with a load from the outside.

The interposition of the nonwoven fabric band 2 in the block 1 group is, for example, that the nonwoven fabric band 2 is laid on the bottom of one block 1, then the upper surface of the adjacent block 1 is passed, and then laid on the bottom surface of the next block 1. Repeat the work.

When a plurality of nonwoven fabric strips 2 are interposed in the group of blocks 1, the interposition positions of the nonwoven fabric strips 2 are alternated as shown in FIG. Lay so that it becomes.

Therefore, the nonwoven fabric band 2 arranged between the adjacent blocks 1 is in the same state as when the blocks 1 are sewn,
As a result, the blocks 1 are integrated by each nonwoven fabric band 2 to restrict the mutual positions.

<C> Laying of upper layer When the laying of one layer of blocks is completed, the laying of one group of upper layers is performed thereon.

Also in the block 1 at this stage, the long nonwoven fabric strips 2 are alternately turned down and laid.

In this way, the entire block 1 adjacent to each layer is constrained by the long nonwoven fabric band 2.

<D> Completion of embankment In this way, the blocks 1 are stacked one by one, and the embankment is completed by covering one layer or the top layer and the surrounding area with earth and sand.

In the embankment constructed in this way, for example, when a horizontal or vertical seismic force is applied, each block 1 group is continuously joined by the non-woven fabric band 2 to receive an external force as a unit and separate into separate pieces. Can be effectively prevented from collapsing.

<Effects of the Present Invention> Since the present invention is constructed in the above order, the following effects can be achieved.

<A> A long continuous nonwoven fabric band was interposed between the blocks of styrene foam.

Therefore, it acts not only against a horizontal load such as seismic force but also against a vertical load such as a direct type earthquake, and does not break apart.

<B> Since the connection between the blocks is strong, it can be applied not only to construction on a flat surface but also to embankment on a slope.

<C> The conventional joining metal fittings interposed between the styrofoam blocks are not required, so that the disposing work and the mounting work are not required, and the construction can be performed quickly.

<D> The mutual positional relationship between the blocks of styrofoam is regulated and determined by the interposition of the nonwoven fabric band.

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

<E> Since a nonwoven band is interposed between all blocks,
Water permeability is easy through this nonwoven fabric, and the stability inside the embankment is improved.
