JP3068934U - Block for law lining - Google Patents

Abstract

(57) [Summary] (with correction) [Problem] To provide a method lining block in which natural stones are superimposed on a concrete slab and have excellent scenery and hydrophilicity. SOLUTION: A substantially rectangular concrete slab 1 has a trapezoidal groove at the center of opposing sides, a trapezoidal convex at the center of the other opposing sides, and a plurality of squares on the surface. This is a block for legal lining in which natural stone slabs 4 of shape are laid and fixed.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to revetment and river shoring, in particular, blocks that cover slopes such as gently sloping shores.

[0002]

[Prior art]

 The present applicant has made various improvements with respect to a block in which natural stone is layered on the surface of a conventional lining concrete block, and has developed an invention such as Japanese Patent No. 2698565. By the way, gentle slope levee is widely used to protect the ground or slope behind from erosion and storm surge.However, in order to cover the slope, development of a block with excellent landscape and hydrophilicity was requested. .

[0003] The present invention has been made to address the above-mentioned demands.

[0004]

[Means for Solving the Problems]

 This invention is a block for lining such as a gentle slope embankment, etc., which has a trapezoidal groove at the center of the opposite side of a substantially rectangular concrete slab and a trapezoidal convex at the center of the opposite side. A plurality of rectangular natural stone plates are laid and fixed on the surface. In some cases, a concave portion is formed on the back surface of the concrete plate. Anchor bars projecting from the back of natural stone are buried in concrete plates. In addition, connecting bars project from the side of the concrete slab.

[0005]

【Example】

 This book has a trapezoidal groove 2 at the center of the opposite side of a substantially square concrete slab 1 of about 1000 × 1500 mm, and a trapezoidal projection 3 at the center of the other opposite side. In this embodiment, a plurality of, in this embodiment, ten rectangular natural stone plates 4 are laid and fixed.

As shown in FIG. 5, the natural stone plate 4 is made of, for example, a 100 mm-thick granite with a cracked finish. The natural stone plate 4 is perforated on the back surface thereof. Are inserted, a solidified material is injected, anchor bars 5 are protruded from the natural stone plate 4, and the anchor bars 5 are embedded in the concrete slab 1 and fixed. Other common natural stones are used as shown in FIG.

In some cases, a shallow groove-shaped concave portion 6 is formed on the back surface of the concrete slab 1. On the side surface of the concrete slab 1, connecting bars 7 used as hook-shaped connecting or anchoring are provided on both sides of the convex portion 3. In use, a suction-preventing material is laid on the slope A, and the chestnut stones 8 and the crushed stones 9 are laid, and the concrete slabs 1 are laid thereon. When the trapezoidal groove portions 2 of the adjacent concrete slabs 1 face each other and the trapezoidal projections 3 abut against each other, hexagonal and slender hexagonal spaces B and C are formed between the concrete slabs 1. , C are filled with mortar or earth and sand if necessary, and then vegetated if necessary.

[0008]

[Effect of the invention]

 This invention consists of the above structure.The concrete slab and the natural stone are firmly integrated by the anchor, the joints between the natural stones can be deep jointed, and the concrete slab can be made inconspicuous from the surface. it can. In addition, the unevenness of the back side of the concrete slab enables stable installation on the slope, and the natural and beautiful landscape can be obtained by the stone-clad construction method. The protruding connecting bars are useful for connecting the concrete slabs to each other, and can be used to attach hanging equipment during the construction. Further, the spaces B and C formed between the adjacent concrete slabs reduce the wave lifting pressure.
