Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lightweight block body which can be used as a substitute for earth and sand or concrete in various types of civil engineering works.

[0002]

2. Description of the Related Art In recent years, lightweight blocks made of styrofoam, which are excellent in lightness, compression resistance and water resistance, have been used as substitutes for earth and sand and concrete.

[0003] Lightweight blocks having a generally rectangular shape are used by being stacked vertically and horizontally.

[0004]

The above-mentioned conventional lightweight block has the following problems.

<A> Simply stacking lightweight blocks does not provide mutual integrity. Therefore, there has been proposed a method of imparting integrity to each light-weight block body using various types of binding hardware. However, there are drawbacks in that it takes a lot of trouble to set the tie, and the construction cost is high due to the tie.

<B> As a method of imparting integrity to each lightweight block body, a method of forming unevenness on the lightweight block body and fitting the same can be considered, but a fitting that can satisfy both conditions of assemblability and integrity. An integrated structure has not yet been proposed.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to provide a lightweight block body which can satisfy both conditions of assembly and integration.

[0008]

SUMMARY OF THE INVENTION The present invention relates to a styrofoam plate comprising a narrow rectangular main body and rectangular overhangs formed integrally at both ends of the main body. A lightweight block body in which a plurality of convex portions and a concave portion that can be fitted with the convex portions are integrally formed on both surfaces of the overhang portion.

[0009]

Embodiment 1 An embodiment of the present invention will be described below with reference to the drawings.

<A> Overall configuration

FIG. 1 shows an example of a lightweight block body 10.
The lightweight block body 10 is a styrofoam plate having a substantially H-shaped planar shape, and has a rectangular main body 11 having a narrow width and rectangular overhangs 12, 12 integrally formed at both ends of the main body 11.
And a plurality of protrusions 13 integrally formed on the upper and lower surfaces (both surfaces) of the overhangs 12, 12, and a recess 14 which can be fitted with the protrusions 13. The main body 11 is narrower than the overhang portion 12 and has cutouts 15 on both sides.

The cutouts 15 are provided in the main body 1 of the overhang portion 12.
A space for fitting the two sets of locking parts 12a, 12a projecting sideways from 1 into the space without any gaps.
The fitting structure of 12a and the notch 15 functions to restrain the horizontal behavior between the lightweight block bodies 10 that have been assembled hierarchically.

Each lightweight block body 10 assembled hierarchically
Convex portion 13 that functions to restrain the vertical behavior between
The concave portion 14 is located at a position deviated to one side from the center of each overhang portion 12, and the convex portion 13 and the concave portion 14 are formed as a pair on the same vertical line.

Each recess 14 is formed by opening the end face 12b side of the overhang portion 12.

This is because the projecting portion 13 is guided from the end face 12b side of the overhang portion 12 to the concave portion 14 so that the lightweight block body 10 can be assembled.

The projections 13 and the depressions 14 are not limited to the shapes shown in the figure, but may have any shape without losing the above-mentioned functions.

<B> Example dimensions

An example of dimensions of the lightweight block body 10 is shown based on FIG. The overall dimensions are 2000mm in length L and 1200m in width T.
m, the height H is 500 mm, and the dimensions of each part are such that the vertical length L1 of each overhang 12 is 500 mm and the vertical length L2 of the main body 11 is 100 mm.
0 mm and the width T1 of the main body 11 is 800 mm. Convex part 1
Each of the recess 3 and the recess 14 has a square planar shape with a side of 500 mm, and the protrusion height and the recess depth are 100 mm each.

The above-mentioned dimensions are merely examples, and are appropriately selected in consideration of the purpose of use and the scale of installation of the lightweight block body 10.

[0020]

Next, a method of using the lightweight block body 10 will be described.

<A> First-stage assembly

FIG. 3 is a plan view of the first stage in which the lightweight block body 10 is laid. Each light-weight block body 10 is assembled in a planar manner while two sets of locking portions 12a, 12a are fitted into the notch 15. At this time, each lightweight block 1
The directions of 0 are all aligned in the same direction.
Assemble the first stage.

<B> Second-stage assembly

When the first stage assembly is completed, the horizontal direction is changed by 90 degrees with respect to the first stage lightweight block body 10, and the second stage is assembled in the same manner as the first stage. 4 shows a plan view when the second-stage assembly is completed, and FIG. 5 shows a longitudinal sectional view when the second-stage assembly is completed. In FIG. 4, the first-stage lightweight block body 10 is indicated by a dashed line.

The convex portions 13 and the concave portions 14 formed on the lower surface of the second-stage lightweight block bodies 10 are fitted to the concave portions 14 and the convex portions 13 on the upper surface of the first-stage lightweight block body 10. And the upper and lower lightweight blocks 10 are connected.

The above first and second steps are repeated to assemble the third and subsequent steps hierarchically. The laminated body of the lightweight block bodies 10 assembled in this manner is such that the upper set of lightweight block bodies 10 is replaced by the lower two sets of lightweight block bodies 1.
The lightweight block body 10 is laid over straddles 0 and 10, and furthermore, one upper set of lightweight block bodies 10 is connected to the lower two sets of lightweight block bodies 10 and 10 via a fitting structure of the concave portion 14 and the convex portion 13.

Further, as shown in FIG. 1, each recess 14 is formed by opening the end face 12b side of the overhang portion 12, so that the protrusion 13 can enter from the end face 12b side of the overhang portion 12. It has a structure to do.

Therefore, it is not necessary to sequentially assemble the lightweight block body 10 from a specific position in a specific direction, and the assembling may be started from arbitrary plural positions.

Further, even when the periphery is incorporated in a space surrounded by the existing lightweight block body 10, the lightweight block body 10 can be incorporated smoothly.

[0030]

[Other Embodiments] In the above-described embodiment, the case where the combination of the convex portion 13 and the concave portion 14 kicked by the opposed protruding portions 12 and 12 is reversed, but the present invention is not limited to this. .

[0031]

As described above, the present invention has the following effects.

<A> Since the lightweight block body is provided with means for fitting in the vertical and horizontal directions, and the lightweight block body can be assembled from the side, a lightweight that can simultaneously satisfy both conditions of assemblability and unity. A block is obtained.

<B> Since the concave portion and the convex portion that can be fitted to the lightweight block body are formed integrally, independent fittings are not required, and assembling labor and construction cost can be reduced.

<C> Since the lightweight block body has a simple shape, it is suitable for mass production.
