Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention uses a large number of small colored blocks to form a mosaic pattern of patterns, letters, etc. on the surface and integrate them into a panel to produce a landscape block. It is about the method.

[Conventional technology]

When drawing patterns such as patterns and letters for landscape beautification on concrete block slopes such as roads, residential areas, retaining walls such as parks, coasts, lakes, river revetments and levees, road surfaces, etc., the following method There is.

A method of drawing a design, etc., using paint on the block surface such as the slope after construction.

A method of forming a mosaic pattern by arranging several types of small blocks (for example, interlocking blocks) with different surface colors on the slope.

[Problems to be Solved by the Invention]

The pattern drawn by the above method is not suitable as a landscape block because it tends to give the viewer a cheesy impression, has no sense of quality, and is difficult to harmonize with the surrounding landscape.

In the method described above, mechanized construction is impossible because the small blocks must be lined up one by one on the slope at the laying site. As a result, there are problems that a large number of laying workers are required and that manpowered work at the laying site is inefficient and the construction period is long.

In addition, due to a serious shortage of workers in recent years,
A concrete block capable of labor-saving construction is desired.

As a method of solving the problems of the above method, in a concrete product factory, a small-sized block of several kinds having different surface colors is pasted on a large-sized concrete plate prepared in advance with an adhesive to form a pattern. The method of arranging these large blocks on the slope of the site is possible. According to this method, the block brought into the laying site becomes large in size, so that mechanized construction is possible. As a result, it is possible to significantly reduce the labor of the laying worker, and to speed up the laying work and shorten the construction period.

[Problems to be Solved by the Invention]

 However, this method has the following problems.

(A) When a small block is adhered to a concrete flat plate, if the flatness of the flat plate becomes poor or the dimensional accuracy of the thickness of the small block is not sufficient, the small blocks forming a mosaic pattern may be misaligned. It is not preferable in terms of appearance.

When an immediate release product such as an interlocking block is used as a small block, the immediate release product generally has a large dimensional error in thickness, and thus unevenness due to steps is likely to occur.

(B) It is difficult to make the gap between the small blocks small, that is, the joint space, to be uniform and beautiful.

(C) A large amount of adhesive is used to integrate the flat plate and the small block, but the cost of the adhesive increases because the adhesive is expensive.

[Means for solving the problem]

The present invention uses an instant demolding colored small interlocking block having a jagged edge and a powder resin sprayed thereon,
A wool felt joint material is interposed on the surface side of the joint between the interlocking blocks, and the interlocking blocks are laid on the bottom plate of the mold so that the surface of the interlocking block contacts the bottom plate to form a mosaic pattern. Mortar is applied on the interlocking block, then concrete is placed on the mortar to form a plate-like body that integrates the interlocking block, and after the concrete effect is removed, the joint material is the interlocking It is a method for manufacturing a mosaic pattern panel block, characterized by peeling and collecting from the joint portion of the block and using it again.

[Action]

 The method of the present invention produces the following effects.

(A) The flatness of the surface of the panel block can be ensured.

(B) Even when using a small block with jagged edges, such as a quick-release type small interlocking block, since the joint part is completely sealed with a joint material of wool felt that has compressibility and flexible water permeability. No leakage of paste on the surface.

Wool felt is suitable as the joint material of the present invention.
Wool long felt (JIS L 320
1), cow wool felt (JIS A 9508), anti-hair felt (JIS
L 3204) and jute felt (JIS L 3203) are suitable. These felts can be reused after being used as joint material, recovered, and then restored to the current state when left in steam.

(C) Since the joint material is permeable to water, the mortar in the joint portion has a dense and beautiful surface due to the water draining action of the surface in contact with the joint material.

(D) It is manufactured efficiently under the condition of quality control in the factory, easy to install and labor saving.

〔Example〕

 FIG. 1 is an explanatory diagram of an embodiment of the present invention.

(A) A large number of small blocks 3 having different colors are laid on the bottom plate 2 of the mold 1 for manufacturing a large block such that the surface of the block 3 is in contact with the frame bottom plate 2. At this time, the small blocks are appropriately arranged so that a mosaic pattern such as a pattern or a character is formed on the surface of the large block after completion, and the joint material 4 is inserted between the joints of the small blocks.

(B) Pour the mortar 5 over the small block 3.

(C) Before the mortar begins to harden, concrete is poured and finished to a predetermined block thickness. At this time, it is preferable to insert the mesh-shaped rebar 7 into the concrete because the strength of the block increases.

Then, after predetermined curing and demolding, the joint material between joints of the small blocks is removed to obtain an integrated panel block 10 as shown in FIG.

In this embodiment, the small block 3 used has a surface area of about 100 to ²⁰⁰ cm ² and a thickness of about 5 to 10 cm. The small block 3 may be manufactured by either a concrete pouring method or an instant demolding concrete manufacturing method, but from the viewpoint of manufacturing efficiency of the small block, the immediate demolding method is preferable because the manufacturing cost is lower.

The coloring of the surface of the small block 3 includes a method of mixing a pigment into concrete at the time of manufacturing the small block, a method of spraying powder resin on the surface of the small block after manufacturing, a method of spraying a resin-based paint, and the like. From the viewpoint of aesthetics, the method of spraying powder resin is most preferable.

Joint material 4 used between the joints of the small blocks 3
Is to prevent the mortar, which is poured later, from invading the boundary surface between the form bottom plate and the surface of the small block to contaminate the surface of the small block and to keep the joint space constant.

Wool felt was used as the joint material. The joint material 4 is a soft material having a high elasticity so that no gap is formed between the joint material and the small block 3, and the cement or sand content in the mortar does not penetrate into the joint material itself. It has such strength that it will not break when it is taken out after completion.

The thickness of joint material 4 (dimension in the joint width direction) is made slightly thicker than the target joint spacing, and the width (dimension in the joint depth direction) is selected according to the target joint depth, but generally 2 to It is about 5 cm.

As shown in the figure, the joint material is inserted below the joints between the small blocks.

When filling mortar, it is necessary to fill the mortar between the joints of the small blocks above the joint material. Poor filling can compromise the integrity of the small block.

Therefore, it is effective to use the vibrator and to make the sand used for the mortar finer in order to improve the filling property.

The amount of mortar to pour is about the top of the small block.
Make it about 5mm thick.

When felt is used as the joint material, the felt is recovered for a while by leaving the extracted felt in steam for a while, so that it can be used repeatedly.

In the panel block 10 manufactured as described above, a large number of small blocks 3 forming a mosaic pattern are jointed mortar 5 and mortar 5 placed on the back side of the small blocks 3.
And the concrete 6 completely integrates.

FIG. 3 shows a panel block 10 manufactured according to the present invention.
It is an example of a surface view of a slope constructed by combining the above. The slope protection block with the mosaic pattern assigned by the original design on the surface can be installed labor-savingly and beautifully using a large work machine.

〔The invention's effect〕

 The following excellent effects are obtained as compared with the conventional method.

Since the mosaic pattern panel block that is brought into the laying site becomes large, mechanized construction is possible and significant labor saving is possible. In addition, since the laying work is speeded up, the construction period is shortened.

Since large blocks with a mosaic pattern are manufactured at a concrete product factory, they are well managed and the mosaic pattern is finished well.

Since the surfaces of the small blocks are manufactured so as to be in contact with the form bottom plate, there is no step difference between the small blocks forming the mosaic pattern after completion even if there is a large dimensional error in the thickness of the small blocks. Aesthetically pleasing.

Since a shrinkable flexible water-permeable joint material is used between joints of small blocks, even if the small block is notched like an interlocking block, the joint spacing (clearance) is finished uniformly, The joint surface is beautiful and aesthetically pleasing. The joint material can be used repeatedly.

The manufacturing cost is low because an expensive adhesive is not used unlike the method of bonding a small block to a concrete flat plate.
