Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete block used for repairing and repairing a natural environment such as a revetment, and to facilitate the revetment of the concrete block. Belongs to the technical field of tooling. 2. Description of the Related Art Conventionally, concrete blocks on which artificial stones used for revetment or the like are arranged are generally mass-produced and constructed in a formwork by expressing a certain geometrical uneven pattern on the surface. When the abutment of each block is straight, it is normal to fill the joint with mortar so that no gap is formed in the straight abutment. There was a block that was constructed so that it could be constructed with appropriate intervals, and after construction, the earth and sand were injected into the joint and the plant was devised so that plants would grow. River currents, lakes and marshes, or rainfall caused spills that eventually washed away the sediment that supported the block roots. Large revetment blocks include retaining wall blocks and large U-shaped gutters, etc. Any of these blocks, including the above blocks, can be constructed by constructing lakes, marshes, river embankments or coasts and hillsides into green. It has made it impossible for insects and small animals to inhabit and destroyed nature. [0003] In view of the state of the prior art of destruction of the natural environment, protection of the natural environment and maintenance or maintenance of the conventional work are required in the construction of seawalls such as rivers, lakes and marshes or coasts, or the prevention of collapse of hillsides along roads. The need for restoration of destroyed nature is called upon during the renovation work at the site, and the provision of a multi-natural type block is particularly required for the blocks used in civil engineering work. No. 2557788, the arrangement of natural stone pattern pseudo stones on the construction surface was irregularly observed, and the joint lines were not linear but also irregular lines, so that the sediment at the joints was not washed away by rainwater flowing on the construction surface. In addition, concrete blocks are provided on the construction block surface so that grass and shrubs can be grown and natural destruction is minimized. In addition, the present applicant provides, as Japanese Patent Application Laid-Open No. 7-118051, pseudo stones extremely similar to a natural stone pattern and a method for manufacturing the stones, and works for protection of gentle slopes, protection of gentle undulations and protection of degraded ground on flat lands, and natural restoration works. We provide artificial stones that are used for protection work on gentle slopes such as hillsides and used to restore the natural environment. [0004] Further, the applicant of the present invention discloses, as Japanese Patent No. 2881642, that the stability of the construction block is sufficiently ensured in the vertical and horizontal directions as well as in the front and rear directions by all being cooperated by the earth and sand introduced into the block during construction. At the same time, the habitat of insects and small animals in the soil in the construction area is also preserved, and the rooting of the plants growing in the gaps formed in the blocks on the construction slope is completely and sufficiently secured, and the stability is maintained. In order to improve the construction of the concrete block, the natural nature of the construction surface is not destroyed. In order to get closer to the natural scenery, the upper and lower surfaces of the concrete block are provided with a two-level horizontal plane. At the joint surface, one horizontal line is prevented from appearing on the entire surface after block construction. These concrete blocks used for revetment with fake stones are square or parallelogram or rhombic, rectangular, etc., and have an area of 1 to 2 m2 (usually considering the convenience of transportation and construction, etc.). The size is 1 square m.) And the weight is large. As shown in FIG. 1, in the construction work of the revetment, a block is set in accordance with a predetermined inclination angle of the inclined surface A such as the revetment. B is piled up on the base C and placed on the entire revetment. At this time, in order to place a heavy block, the entire block is restrained by a rope, or the rope is penetrated by a concrete block. A hole was provided and restrained by a rope, suspended by a crane and placed at a predetermined construction site. [0005] However, the patent
The concrete block with artificial stones placed on the entire pedestal of No. 2881642 prevents one horizontal line from appearing on the entire surface after block construction at the upper and lower joint surfaces of the block, but it is not enough, In addition, since it is difficult to manufacture a complicated asymmetrical shape and the production cost is high, there is a demand for a concrete block to be used for revetment or the like, which can be easily manufactured with a complicated geometric uneven pattern. In addition, when constructing concrete blocks used for revetment with fake stones, etc., the blocks must be heavy and must be constructed at a slight angle of inclination. Had the problem that it required a lot of labor and several people. There is also known a method in which an engaging hole through which a rope is penetrated is provided in a concrete block, the rope is constrained by the rope, transported and moved by a crane, and the construction is carried out. However, there is a problem in that a lot of labor and a plurality of people are required, and the provision of the engaging hole through which the rope is penetrated in the concrete block is not easy to process and requires much time and labor. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and one of the problems is that, in order to harmonize with the natural scenery, one horizontal line is formed on the upper and lower joint surfaces of the concrete block. Another object of the present invention is to provide a concrete block having a more complicated geometrical uneven pattern, which does not appear on the whole surface after the construction and is easy to manufacture, and one of the other problems is to go to the construction site of the concrete block. It is easy to move, and according to the slope of revetment work,
An object of the present invention is to provide a concrete block and a tool for applying the same, which can be easily installed on a delicate angle of inclination, and in which even a single worker can apply a pseudo-stone block such as seawall. [0007] In order to solve the above-mentioned problems, the invention according to claim 1 is a revetment comprising a surface portion, a stay portion, and a trunk portion having a wide gap in a vertical direction. A concrete block having a pair of triangular prism-shaped protrusions for moving the block formed substantially at the center of the inner wall surfaces of the face portion and the holding portion facing each other. A fitting portion that presses and presses the triangular prism-shaped convex portion to the outside of the surface portion and the holding portion, a connecting portion that is connected to the fitting portion and extends to the outside from a gap in the body portion, and approximately the connecting portion. A hanging portion connected to a right-angled L-shape and extending forward of the block is provided. The hanging portion is provided with a plurality of hanging angle adjusting holes in a longitudinal direction, and the hanging device is suspended by selecting the angle adjusting hole. Tilt the block to a certain angle when lowered A concrete block and its application tool, characterized by being combined with a concrete block application tool that can be used. An embodiment of a concrete block and a tool for applying the same according to the present invention will be described with reference to the drawings. [Concrete Block] FIG. 2 is a perspective view of a concrete artificial stone block of this embodiment, which is composed of a surface portion 1, a body portion 2, and a retaining portion 3, and the surface portion 1 and the retaining portion 3 have the same shape, front, rear, left and right. In the specific polygonal geometric shape which can be continuously assembled in the surface part 1, the surface part 1 arranges a plurality of pseudo stones 12 on the pedestal 11 and makes each pseudo stone 12 contact each other, and the gap between the pseudo stones A plurality of water holes 13 through which river water etc. circulate are provided, and the pedestal 11 and each artificial stone 12 are integrated, and the retaining portion 3 and the surface portion 1 have the same shape and the same size as the specific polygonal shape, and have an appropriate thickness (about 5 cm). )

The body part 2 which connects the surface part 1 and the holding part 3 to form an integral body is composed of a pair of horizontal cooperating parts 21 and 22 having an appropriate interval (20 cm), and forms an opening 23 which forms a wide gap penetrating in the vertical direction. Have. Here, the "wide gap" means a space wide enough for the fitting portion 41 of the application tool 4 to enter and exit, as described later. Further, a convex portion 23 is provided at an upper portion of the horizontal cooperation portions 21 and 22, and a concave portion 24 is provided at a lower portion, and the upper and lower blocks are fitted and fixed to each other at predetermined positions. The inner wall surface 1 of the surface portion 1 and the holding portion 2 facing each other
4, 31 are formed with engaging portions 15 for locking and moving the blocks, each of which has a convex portion 15a having a triangular prism. The projection 15a of the triangular prism can be easily formed at the time of forming the block, and the molding is remarkably easy as compared with the conventional hole formation or cutting in a through hole for rope penetration,
Production costs will also be lower. The shape of the surface 1 is the same as that of the retaining portion 3, but as shown in FIG. 3, the surface 1 is a polygonal geometric shape which can be continuously assembled in front, rear, left and right directions. Reference numeral 17 denotes a point-symmetrical shape at the center of the plane of the pedestal 11. The upper surface 16 has three horizontal surfaces 16a, 16b, and 16c, and the lower surface 17 has three horizontal surfaces 17a, 17b, and 17c. The width of the horizontal surfaces 16a, 16c, 17a, 17c on both sides of the upper and lower parts 16, 17 is the same length, and the upper and lower parts 1
The horizontal position at the left and right ends 16d, 16e, 17d, 17e in 6, 17 is the same, and the connecting surfaces 16f, 16g, 16h, 17f, 17g, 18h of each step are 45
The surface portion 1 includes a pedestal 11 and a plurality of artificial stones 12 on the pedestal. Further, the left and right side surfaces 18 of the surface portion 1 are formed with two levels of vertical surfaces 18a and 18c having the same width, and have a connecting surface 18b having an inclination of 45 °. Therefore, when this block is rotated 180 ° about the center of the block pedestal 11 as a central axis, it becomes exactly the same shape as before rotation, and there is no need to worry about up and down at the time of construction, and it is almost the same as adjacent front, rear, left and right blocks It works so as to make surface contact without any gap and to firmly lock blocks adjacent to each other. The overall dimensions of the actual concrete block in the present example are about 50 cm in length and about 100 cm in width, and the width of the three horizontal planes is almost equal and the steps are 4 cm and 8 cm, but the vegetation flourished Sometimes, in order to make the horizontal lines as prominent as possible, preferably 3
About 10cm is good. In addition, since the above-described surface portion 1 can have a complicated polygonal geometric shape, a plurality of pseudo stones 12 having various shapes can be arranged on the surface portion 1 in FIG. 3, as shown in FIG. Two or more relatively large artificial stones 12A,
12B, 12C, 12D can be freely designed, and 12a, 12b, 12c, 12d are arranged between them, and each stone on the pedestal 11 and each stone on the left, right, top and bottom adjacent blocks are If the stones are arranged so as to be in contact at three or more places, each stone is supported at three points and acts as if it were a brace, becomes firm, and has a strong appearance. The horizontal part of the upper and lower surfaces of the block has three steps, and when the vegetation grows thicker, the horizontal lines become more prominent as much as possible, so that it matches the natural landscape where natural stones are arranged more naturally. When the vegetation grows,
Since the vertical surface does not show much vertical lines, it may be about two steps, and the angle of inclination of the connecting surface may be 90 ° instead of 45 °, or another shape as long as it is fitted closely. [Concrete Block Tool] Next, the concrete block as described above can be easily transported and moved to a construction site, and has a delicate angle according to the inclination angle of the revetment at the construction site. A tool that can be easily installed on an inclined surface will be described. In FIG. 5, convex portions 15a and 32a of engagement portions 15 and 32 for block movement are formed at substantially the center of the inner wall surfaces 14 and 31 of the surface portion 1 and the holding portion 3 facing each other. A wide gap 23 penetrating in the direction is formed. The application tool 4 used for moving the block includes a fitting portion 41 in which a pair of side cross sections of the inner wall surfaces 14 and 31 are fitted to the triangular prism-shaped convex portions 15a and 32a, and a body portion 2 connected to the fitting portion 41. A connecting portion 42 extending from the gap 23 to the outside and a hanging portion 43 connected to the connecting portion 42 in an L-shape at substantially right angles and extending forward of the block are provided. It is a configuration to be hung. The fitting portion 41 has a configuration in which a pair of triangular prism-shaped convex portions 15a and 32a of the inner wall surfaces 14 and 31 are pressed outward, and a buckle 44 that is internally threaded in opposite directions is provided at the center. At both ends of the buckle 44, fitting members 45a and 45b provided with male screws integrated with the screws of the buckle 44 are provided,
The fitting members 45a and 45b are provided with inverted triangular prism concave fitting portions 46a and 46b which fit into the triangular prism convex portions 15a and 32a.
A connecting portion 42 extending outward from the gap of the body 2 is provided on the side fitting member 45a, and a suspending tool 43 connected in an L-shape substantially perpendicular to the connecting portion 42 and extending forward of the block is provided. The hanging tool 43 is hung on the hook 5 of the moving device. A plurality of suspension angle adjustment holes 47 are provided in a row in the longitudinal direction in the suspension portion 43, and one of the suspension angle adjustment holes 47 is selected for use. The angle of inclination of the entire block D2 when suspended is different. When constructing a concrete block on a revetment, etc., select a plurality of angle adjustment holes 47 according to the weight of the concrete block to be used and the angle of the slope of the revetment work. The hanging ring 48 that engages with the hook 5 is fitted, and the block D2 is suspended and transported / moved by the hook 5 of the moving device via the hanging ring 48 with a predetermined inclination. [Concrete Block Construction Method] A method of using a concrete block application tool will be described with reference to FIG.
In, the blocks are stacked on a base (not shown). When the next block D2 is to be stacked on the uppermost block D1 that has been stacked, first, the application tool 4 is attached to the next block D2 in a place where a block carrier or a block is prepared. And tool 4
The buckle 44 of the fitting portion 41 is rotated in the reverse direction to
The distance between 45a and 45b is short, specifically, the width of the gap 23 of the body 2 and the pair of triangular prism-shaped projections 15a and 32a on the inner wall surfaces 14 and 31.
, The fitting portion 41 of the tool 4 is inserted into the gap 23 of the body 2, and a pair of triangular prism-shaped protrusions of the inner wall surfaces 14 and 31 for block movement to be locked to the tool 4. Corresponding to 15a and 32a, the buckle 44 is rotated forward in a direction to increase the distance of the fitting portion 41, and the fitting portions 46a and 46b are moved outward. Then buckle 4
The fitting member 45a, 45b on the male screw side integrated with the female screw of 4 is fixed by fitting into the triangular prism-shaped convex parts 15a, 32a and pressing the inner wall surfaces 14, 31 to the outside, When a heavy block is lifted, it is pressed and fixed so that it does not come off or shift. At this time, when the block D2 having a constant weight is hooked down by the hook 5, the angle α of the inclination of the surface portion 1 with respect to the vertical is α.
And the angle adjustment hole 47 such that the angle β of the inclined surface A matches.
Is selected in advance, and the ring 48 is engaged with the angle adjusting hole 47. Here, a hook 5 of a moving device such as a crane is engaged with the block D2 to which the application tool 4 is attached, and the hook 5 is fitted into a predetermined angle adjusting hole 47 by a ring 48.
And lifted it with a crane, and moved it to the vicinity of the block D1 where the work has already been performed. In the new block D2 suspended near the upper part of the completed block D1, the angle α of the inclination of the surface portion 1 with respect to the vertical and the angle β of the inclined surface A coincide with each other. There is no need to adjust the angle by simply placing it on the slope A and the completed block D1, and only fine adjustment is required for the fixed installation of the block D2 on the slope A. It is needless to say that the present invention is not limited to the above-described embodiment unless the characteristics of the present invention are impaired. For example, when the vegetation grows on the left and right surfaces of the block, the vertical surface does not show much vertical lines. Therefore, it may be about two steps, but it may be stepless or three steps, and even if the inclination angle of the connecting surface is not 45 °
° or other shapes as long as they fit closely. Further, in the present embodiment, the pair of engaging portions provided on the inner wall surfaces 14 and 31 are the triangular prism-shaped convex portions 15a and 32a, but may alternatively be triangular prism-shaped concave portions. However, as long as the engagement with the application tool is reliable, it is of course possible to use other half-polygonal pillars such as a half-square pillar or a half-cylinder. At this time, the shape of the fitting portions 46a and 46b of the application tool may be concave or convex in accordance with the shape of the employed engaging portion. [0016] As described above, according to the first aspect of the present invention, the surface portion, the holding portion, and the trunk portion having a wide gap in the vertical direction. A pair of triangular pillars for moving blocks, which are concrete blocks used for revetments and the like that are constructed, and approximately at the center of the inner wall surfaces facing each other on the surface and the recess.
