JPH03250118A - Connecting fitting for foaming styrene block - Google Patents

Abstract

PURPOSE:To improve work efficiency and reduce a construction cost by riveting needle bodies, provided with clinch claws formed at the tip part thereof, to foaming styrene blocks so as to laminate the foaming styrene blocks while jointing them rigidly. CONSTITUTION:Needle bodies 3 provided, at the tip parts thereof, with clinch claws 4 formed of faces 4a inclined in relation to the axial center are protruded vertically from the center parts of both side faces of a circular flat plate 2 to form a connecting fitting 1. A part to be constructed is placed flat, and EPS blocks A1 at the lowest stage are laid horizontally. The connecting fittings 1 are then riveted at appropriate places, and second stage EPS blocks A2 are placed successively and thrusted with the needle bodies 3 protruding from the connecting fittings 1. At this time, both EPS blocks A1, A2 are riveted by the clinch claws 4 so as to be laminated positively. Lamination is further performed in the same method, and after reaching the desired height, earth filling or the like is performed.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Industrial Application Field The present invention relates to a connecting fitting used when constructing roads and embankments on soft ground by laminating expanded polystyrene blocks (hereinafter referred to as EPS blocks).

(2) Prior art As shown in FIG. 7, there is a conventional disc in which needle-shaped bodies (b) are protruded from the center of a disc (a) on both sides thereof.

(3) Problems to be solved by the invention However, the above-mentioned connecting metal fittings have a strong locking force in the XY force direction, but a weak locking force in the Z direction, and the EPS is caused by wind pressure etc.
This method has problems such as the blocks moving upward, creating gaps between the EPS blocks, and the need to redo the lamination process, resulting in poor work efficiency and high construction costs.

It is an object of the present invention to solve the above-mentioned problems, to ensure the bonding between EPS blocks, to increase the bonding strength, to improve work efficiency, to speed up construction, and to reduce construction costs.

(4) Means for Solving the Problems In order to achieve the above object, the present invention provides needle-like bodies protruding from both sides of a flat plate, and rivets the needle-like bodies to a Styrofoam block so that each Styrofoam blow In the connecting metal fitting in which seven strands are tied together and laminated, a folded claw is formed at the tip of the needle-like body.

(5) Function When the connecting fitting is inserted into the EPS block, the folded claw at the tip of the needle-like body of the connecting fitting will bite into the EPS block to prevent it from coming off, and the EPS blocks will be firmly stacked on each other and loosen. Construction can be carried out quickly without any problems.

(6) Example Hereinafter, one example of the present invention will be explained with reference to FIGS. 1 to 4.

(1) indicates a connecting fitting, and the connecting fitting (1) is made of metal or synthetic resin and protrudes perpendicularly from the circular flat plate (2) and the center of both sides of the flat plate (2). needle-like body (
3), (3) and 11. The needle-like body (3), (
3) has a surface (4a) inclined with respect to the axis at the tip.
(4a) A sickle-shaped folded claw (4) is formed. Note that (A), (Aρ, (A2), (A3), etc.) indicate EPS blocks.

Next, a method for stacking EPS blocks using the connecting fitting (1) of the present invention will be explained.

In FIG. 4, first, the area to be constructed is flattened and the lowest EPS block (Aρ) is laid horizontally.

Next, after riveting the connecting fitting (1) to the appropriate position from the left end of the EPS block (Aρ), the second stage EPS block (
A,) are placed one after another and inserted into the needle-shaped body (3) protruding from the connecting fitting (1). At this time, the folding claws (4) of the needle-shaped body (3) rivet the first-stage EPS block (A7) and the second-stage EPS block (A2), and the two are securely laminated. never moves. Then, the second stage EPS block (A2) is laid, and then the second stage E
A third EPS block (A3) is stacked on top of the PS block (A,) in the same manner. After reaching the desired height in this way, earth mounding, etc. is carried out to complete the work.

FIG. 5 shows another embodiment of the present invention, in which the flat plate (2) of the connecting fitting (1) is square, and the flat plate (2) has four
The needle-like bodies (3)...(3) are placed on the lower surface of -L at the corner, respectively.
is vertically protruding.

Therefore, as shown in FIG.
A), by riveting between (A), the adjacent EPS
It has the feature that blocks (A) and (A) can be bonded together, and stacked EPS blocks can also be bonded together reliably. The connecting fitting (1) can also be used by being riveted to the side surface of the EPS block.

It is also possible to increase the binding force by forming a plurality of folded claws (4) provided at the tip of the nail-like body (3).

(7) Effects of the Invention As described above, according to the present invention, since the folding claw is formed at the tip of the sword-shaped body protruding from the connecting fitting, the folding claw bites into the EPS block and prevents it from coming off. The bonding strength between each EPS block is increased, and there is no occurrence of displacement or loosening, which has the effect of improving work efficiency and reducing construction costs.
