SUMMARY OF THE INVENTION The present invention relates to a variable-height concrete lining block unit capable of easily performing uneven construction between individual lining blocks at a site for lining a construction surface. provide.

[0004]

Each of the lining blocks forming the variable-height concrete lining block unit is made of a hexagonal, square, triangular, or circular concrete block, and adjacent lining blocks. Has a joint between the side surfaces of which can select a connecting position in the height direction, and has a structure in which a step in the height direction can be formed between adjacent lining blocks by selecting the joint.

[0005] As the joint, a plurality of tenon holes or tenon grooves are provided on the opposing side surfaces of the adjacent lining block at intervals in the height direction. The mortise or tenon groove of the one lining block and the other are installed at positions corresponding to each other.

At the site, one of the mortises (or tenon grooves) of the adjacent two lining blocks is selected, and the tenon is inserted between the two tenon holes with the two mortises facing each other. As a result, the connecting position in the height direction between the side surfaces of the two lining blocks is selected, and the step laying with a difference in the relative height between the two lining blocks is possible. At the same time, it is possible to lay the two lining blocks without any difference in the relative height.

As another example of the joint, a tenon hole or tenon groove is provided on the side surface of one of the adjacent lining blocks at intervals in the height direction, and the tenon hole or tenon hole is provided on the side surface of the other lining block. A tenon is provided for selecting a tenon groove.

[0008] By inserting a tenon of the other lining block into one of the tenon holes (or tenon grooves) of one adjacent lining block at the site, the height direction between the side surfaces of the two lining blocks is increased. The connection position is selected, and a difference can be made in the relative height between the two lining blocks, so that the blocks can be laid step by step. At the same time, it is possible to lay the same level without giving a difference in the relative height of both lining blocks.

The above-described structure is established between adjacent concrete lining blocks on a large-area construction surface. The above-mentioned uneven laying and equal-level laying can be selected at an arbitrary location on a wide-area lining surface and can be performed on site, and three-dimensional and near-natural lining is possible.

When lining work is performed on a riverbed, for example, a riverbed, using the lining block unit, a space with fish roots can be formed under the stepped (increased) lining block, It is also useful as a fish nest block. That is, the present invention is a novel proposal as a fish nest block structure.

As described above, the step lining by the concrete lining block can be easily performed on site by a simple means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a deformable concrete lining block unit according to the present invention will be described below with reference to FIGS.

The variable-height concrete lining block is an octagon, hexagon, square, pentagon, triangle, or the like, or a circular lining block.

As an example of a shape in which the present invention can be effectively utilized, the lining block 1 is formed into concrete in an octagonal shape, and the adjacent lining block in the construction surface lining is shown in FIG.
As shown in B and C, a joint structure is provided between the opposing side surfaces so that a connecting position in the height direction can be selected.

That is, the adjacent lining block 1 has a structure in which a plurality of sets of joints 2 can be formed in the height direction. Then, by selecting the joint 2, as shown in FIGS. 1A and 1B, adjacent lining blocks 1 a and 1 b are assembled and laid in a high or low step.

Alternatively, as shown in FIG. 1C, by selecting a joint in the height direction, an adjacent lining block is laid at the same level with respect to the construction surface.

An example of the joint 2 will be described with reference to FIGS.

As an example, as shown in FIG. 2, each of the joints 2 is formed by molding each lining block 1 made of concrete into an octagon, and is provided on all the opposing side surfaces of each adjacent lining block 1 in the height direction. To form a plurality of mortise holes or tenon grooves 3.

The mortise holes or mortise grooves 3 are equally spaced in the height direction and are formed at positions corresponding to those of the adjacent lining block 1. Alternatively, the mortise holes or tenon grooves 3 are formed at irregular intervals in the height direction, and are formed at positions corresponding to each other between adjacent lining blocks 1.

As shown in FIG. 3, an arbitrary tenon (mortise) 3 of one adjacent lining block 1 and an arbitrary tenon (mortise) 3 of the other lining block 1 are selected. , Both mortise holes (mortise groove) 3 facing each other
A tenon 4 is inserted between the three to form a joint 2.

As shown in FIGS. 5A and 5B, one of the joints 2 capable of changing the connecting position in the height direction between the side surfaces of the adjacent lining blocks 1 is selected, and the relative height of the two lining blocks is adjusted. Assembling and laying are performed at different levels with differences.
At the same time, as shown in FIG. 5C, it is possible to lay the same level without giving a difference in the relative height between the two lining blocks 1.

In particular, as shown in FIG. 5B, the present invention is useful as a lining structure for assembling and laying each adjacent lining block 1 in a stepwise manner on a sloped surface or a flat construction surface.

In this step-like lining structure, each lower lining block 1 selects a tenon hole or tenon groove 3 on the upside surface except for the lowest, and each upper lining block 1
Selects a tenon or mortise groove 3 except for the topmost one existing on the down side, and inserts a tenon 4.

As shown in FIG. 4, the connection in the oblique direction or the like can be freely performed by selecting the side surface used for connection of the octagonal lining block 1, and another lining block can be connected to the lining block. By providing an unconnected free side surface, a free space of the lining block can be formed, and this can be used as a plant growing space 5. The same applies to hexagonal and quadrangular lining blocks.

Further, a space 8 with fish roots can be formed below a high-level lining block assembled in a stepped manner, which is useful as a fish nest block structure. This is also true for hexagonal and square lining blocks.

Next, another example of the joint will be described with reference to FIGS.

As shown in FIGS. 6 and 7, each lining block 1 made of concrete is formed into, for example, an octagon, and a plurality of lining blocks 1 are arranged on the side surface of one adjacent lining block 1 at intervals in the height direction. A mortise or mortise groove 3 is formed, and a tenon 4 ′ for selectively inserting the mortise or mortise groove 3 is integrally provided on the side surface of the other lining block 1.

The mortise holes or tenon grooves 3 are equally spaced in the height direction, or the tenon holes (mortise grooves) 3 are irregularly spaced in the height direction.

An arbitrary tenon hole (mortise groove) 3 of the adjacent one lining block 1 is selected, and the other lining block 1 is selected.
8A and 8B, a step having a difference in the relative height of both adjacent lining blocks by performing lining on the construction surface while inserting the tenon 4 and forming an arbitrary joint 2. Assembly and laying are performed. At the same time, as shown in FIG.
It is also possible to lay the same level without giving a difference in the relative height of the two lining blocks 1.

In particular, as shown in FIG. 8B, the present invention is useful as a lining structure for assembling and laying each adjacent lining block 1 in a stepwise manner on a sloped surface or a flat construction surface. In this step-like lining structure, each upper lining block 1 selects a tenon or mortise groove 3 excluding the topmost one existing on the down side surface, and each lower lining block 1 has an up side surface. Insert tenon 4

As described above, each of the above-described configurations is established between adjacent concrete lining blocks on a large-area construction surface.

Therefore, for example, when each lining block 1 is a quadrangular lining block, the connecting position in the height direction is selected between all four adjacent sides or between two opposite sides or three opposite sides. The joint 2 is composed of a tenon (mortise groove) 3 and tenon 4, 4 'of a possible configuration.

Similarly, in the case of an octagonal lining block, for example, the connection position in the height direction can be selected in all eight sides or every other four sides among all eight sides. The structure is such that a joint comprising a tenon (mortise groove) 3 and tenon 4, 4 'can be formed.

For example, in the first example of FIGS. 2 to 5, mortise holes or tenon grooves 3 are formed on all side surfaces of a lining block 1 such as an octagon, a hexagon, or a square, and Selected tenon (mortise) facing the side of block 1
A tenon 4 is inserted in between to assemble and lay the steps.

In the second example shown in FIGS. 6 to 8, for example, in the case of an octagonal lining block, the tenon or tenon groove 3 is provided on every other four sides of all eight sides in the height direction. Mortise 4 'is integrally protruded from the remaining four sides, the tenon 4' is inserted into the selected tenon hole (mortise groove) 3, and the step assembly and laying are performed. .

Similarly, in the rectangular lining block 1, a tenon or tenon groove 3 can be provided on two opposing sides, and a tenon 4 'can be provided on the other two opposing sides.

In the second example, an octagonal, hexagonal or quadrangular lining block 1 is provided with a female lining block provided with tenon holes (or tenon grooves) 3 on all side surfaces thereof, and a lining block 1 having all side surfaces. By forming two types of lining blocks including a male lining block provided with a tenon 4 ', a step assembly and an equal-level assembly can be performed by selecting the joint.

The present invention can be practiced even when the lining block 1 is circular. Mortise holes (mortise grooves) 3 and tenon 4, 4 'are provided at equal intervals on the peripheral surface of the circular lining block 1. Plural sets of joints 2 in the height direction between adjacent lining blocks 1
Can be formed.

FIG. 11A shows the mortise 3 of the first and second examples, and FIGS. 11B and 11C show the mortise 3. The mortise groove 3 may be a groove in which both ends are not open as shown in FIG. 11B, or a groove in which both ends or one end is open as shown in FIG. 11C.

The tenons 4, 4 'of the first and second examples are shown in FIG.
Make a pin-shaped tenon as shown in 2A. Or FIG. 12B,
As shown in FIG. 12C can be applied to the tenon groove 3 having an open groove shown in FIG. 11C, and the tenon 4, 4 'of FIG. 11B can be applied to the tenon groove 3 in which both ends are not opened. it can.

FIG. 12D shows an example in which the tenons 4, 4 'are formed in a hook shape or a ring shape. These hook-type or ring-type tenons can be easily processed by bending a metal wire and can be easily embedded in concrete. Also, the tenon 4 in the first example is inexpensive and suitable. This hook-shaped or ring-shaped tenon 4 is advantageous when adjacent lining blocks 1 are connected so as to be difficult to separate as shown in FIGS.

For example, a connecting pin 6 composed of a headed pin or a simple straight pin is inserted from the front side of the lining block 1 and inserted into the tenons 4, 4 '. That is, the connecting pin 6 is inserted into the lining block 1 from a direction orthogonal to the insertion direction of the tenons 4, 4 ', and inserted into the tenons 4, 4'. As a result, the adjacent lining blocks 1 are prevented from coming off of the tenons 4 and 4 ′ by the connecting pins 6, so that both blocks 1 are hardly separated via the tenons 4 and 4 ′.

Also, as shown in FIGS.
By providing a connecting hole 7 for inserting the connecting pin 6 indicated by a virtual line in the drawing, the lining blocks can be connected to each other in cooperation with the connecting pin 6. A hole for inserting the connecting pin 6 is provided in the lining block 1 in advance.

As a development example of the above-mentioned connecting structure, a large collective block in which several lining blocks 1 are connected in advance by the connecting pins 6 is formed, and this collective block is lifted by a crane and required for a work surface. Set up at a location. In this case, the individual lining blocks 1 that form the collective block exhibit flexural properties at the connecting portions, and can be adapted to the construction surface.

[0045]

As described above, the joint structure in which the connecting position in the height direction can be selected between the opposing side surfaces of the adjacent lining blocks is formed. The uneven assembly and equal-level assembly between the engineering blocks can be freely performed, and by using these uneven assembly and the equal-level assembly together in a large-area construction surface, a three-dimensional and near-natural lining work can be performed.

Also, stepwise lining is easy. In addition, when used as a riverbed lining structure, a space with fish roots can be formed below a stepped high-level lining block, and it can be expected to be used as a fish nest block.
