Description

[Detailed description of the invention] The object of this invention is to create a seawall around oil for ornamental fish and aquatic plants.
Mainly related to the structure of Hyotan mixed blocks.

The purpose is to allow even an amateur to easily create a gourd-shaped or circular pond that does not leak water.

In other words, in the past, this type of pond was mainly built using stones and condensed water for bank protection, and the method of building a water tank in advance with concrete and constructing it was quite a major undertaking even for an expert, so instead of building a water tank, you could directly use stones etc. How to line up the stones and solidify the space between them with concrete.

It is difficult to completely prevent water leaks, but the latter method is often used even by experts because it is easy to install. Although this cannot be completely prevented, the finished product is often unsightly, and it is not easy to transport stones, the present invention uses a method of arranging pre-made blocks and hardening the joints with mortar. Even an amateur can easily create a water-tight pond in any shape and without water leakage.

Next, the present invention will be explained according to the drawings.

1 to 4 show embodiments of the blocks of the present invention.

That is, the material of the block is made of waterproof concrete or hard plastic, and its size is usually 45 crrL to 50 crrL in width, 20 crrL to 25 crrL in height, 3 cIrL to 4 cm in thickness to make it convenient to carry. However, in the case of a block with a small radius that forms an arc, the width of the block is appropriately shortened, that is, the block is formed by curving the longitudinal direction into an arc shape with an appropriate radius. In order to make the shape of the gourd more satisfying when the blocks are arranged, blocks with arcs of different sizes are usually prepared, consisting of three types of arc radii: large, medium, and small. By appropriately combining them, you can obtain a hyotan pond or inner oil of the desired shape.

That is, as described above, along the center of both end surfaces of the block body 10 formed in a curved manner, the cross section running vertically is semi-circular in length and width.
A lateral groove 3 having an inverted triangular cross section is provided on the upper surface along the curved surface, and a protrusion 4 to be fitted into the lateral groove 3 is formed on the lower surface.

That is, when the block bodies 1 are stacked in two or three stages, the protrusions 4 on the lower surface of the second stage block body are formed so as to properly fit into the horizontal grooves 3 on the upper surface of the lower stage block body. Therefore, the connecting parts between the horizontal grooves 3 and the protrusions 4 and the plane part 5 before forming them are smooth and continuous by rounding the corners so as not to impede the flow of the mortar 6 during construction. 1. In order to make the thickness of the mortar 6 filled into the gap between the upper and lower blocks uniform during construction, protrusions I are provided at both ends of the protrusions 4 on the lower surface. The protrusions 7 are provided at three locations, two on the inner periphery of the arched protrusion 4 near both ends in the longitudinal direction, and one on the outer periphery at the center.

The condition when the horizontal groove 3 is filled with mortar 6 and the upper block is stacked is shown in Fig. 5 A2.

In other words, if the horizontal groove 3 is sufficiently filled with mortar 6 (see figure A) and the upper block is placed on it, the tips of the protrusions 4 will easily bite into the mortar 6, and the weight of the block itself will push the block down. As a result, the protrusions 4 easily push away the mortar 6, and the protrusions 7 come into contact with the flat surface 5 of the lower block to stabilize it (see mouth opening).

At this time, the gap formed between the horizontal groove 3 and the ridge 4 has a wave-like shape, but as mentioned above, the corners are rounded and smooth, so the mortar 6 flows smoothly, and the mortar Since the mortar 6 is compressed and extruded from the center toward both sides, there is no cavity left in the gap, and the excess mortar 6 protrudes to both sides and hardens, completely preventing water leakage in this area. It's something you get.

Therefore, fenestrations 8 are formed near both ends of the horizontal groove 30, and the vertical grooves 2 at both ends are formed slightly deeper from the fenestrations 8, and a cutout 9 is inserted into this during construction. It is made up of

FIG. 6 shows a state in which a cutout 9 is inserted into each fenestration 8 of an adjacent block.

FIG. 7 shows a cross section of the main part when construction is carried out with the cutout 9 inserted.

That is, during construction, the vertical grooves 2 of the adjacent blocks are filled with mortar 6, and the fenestrations 8 are also filled with mortar 2, and the slats 9 are inserted into this to further raise the mortar 2 and are fixed integrally with the blocks. be.

This allows the blocks arranged in a circle to easily tilt toward the outer circumference, and even though the circumference is extended, the tensile force of the mortar (or concrete) cast into the vertical grooves 2 is weak, so the joints can be easily formed. Concerns about peeling and water leakage can be fully prevented.

Figure 8 shows an example of the shape of a pond pond constructed using the blocks of the present invention.

In this example, two types of blocks having arcs with radii α and β are combined, and the blocks do not necessarily have to be arranged in a perfect circle that is faithful to the curved surface, but can be slightly distorted. Because of this, it is possible to obtain an arbitrary gourd shape, and in such an arrangement of blocks, the flocs located at the bottom and top of the gourd shape collapse toward the inner circumference. However, since more than half of the height of the block is usually buried in the soil, collapse towards the outer periphery is extremely rare. A, B located in the part of
Since there is a sufficient possibility that only blocks C and D may collapse toward the oil side, if these blocks and their neighbors on both sides are connected and fixed to each other with casing shells 9, their collapse can be completely prevented.

Figure 9 shows the outline of a two-tiered construction example. According to this block, in a pond for aquatic plants, one-tiered stacking is sufficient for water depth, but in the case of ornamental fish oil, two-tiered stacking is usually required. considered appropriate.

Therefore, the order of construction in such a case is generally to first fill in the vertical grooves 2Vc mortar 6 at the joints of the general blocks arranged in the desired gourd shape, and then fill in the horizontal grooves 3 and fenestrations 8.
Fill the groove with enough mortar 6 so that it rises slightly from the edge of the groove.
A method is used in which casings 9 are pushed into fenestrations 8 at key points, mortar 6 is placed on them, and then the second stage of blocks is stacked.

In addition, the pond bottom can be sufficiently prevented from leaking even if the concrete is poured after the edge of the pond is protected with blocks.

The tops of the blocks that have been revetted can be flattened by filling the horizontal grooves 3 with mortar 6, or the edges can be made wide with concrete, and tiles can be placed over this to improve the aesthetic appearance. .

In this way, according to the block of the present invention, even an amateur can make a gourd-like or meat pond extremely easily by using the curved surface of the block, and during construction, it is possible to stack the blocks on top of adjacent blocks. The mortar 6 spreads smoothly into the gaps between the vertical grooves 2 and lateral grooves 3 and the protrusions 4 between the block and leaves no cavities in the gaps, completely preventing water leakage. Construction is extremely simple as all you have to do is pour concrete after the edges have been created, and in addition, work such as applying mortar usually requires considerable skill, but the blocks of this invention have the ability to Since the deep horizontal groove 3 is formed on the top surface, it has the advantage that even an amateur can easily fill it with an appropriate amount of mortar, and if it is made of lightweight blocks made of plastic etc., it can be used for buildings with a simple structure. You can easily create and enjoy a pond even on your rooftop.
It is extremely convenient and useful.
