Description

[Detailed description of the invention] This invention relates to the improvement of blocks for slopes attached to slopes such as road cutting surfaces, and is a combination of a basic block body, a connecting block body, and an auxiliary block body. By connecting, it is possible to change the pattern that appears depending on the arrangement of the blocks, and it is also possible to freely combine them according to the road slope and embankment slope, and the periphery of the slope can be connected to the connecting block body and the auxiliary block body. It is an object of the present invention to provide a legal frame block that can be constructed in a straight line and at right angles with a corner block body and a corner block body.

Hereinafter, one embodiment of the present invention will be described based on the drawings.
1 is a basic block body, 2:3 is a connecting block body, 14 is an auxiliary block body, and 17:18 is a corner block body, all of which are molded from concrete.

As shown in Fig. 1, the basic block body 1 is a hollow frame body with a square front shape, and connecting arms 4at, 4bt, 4ct, and 4d are arranged diagonally outward at the square parts of the square. The connecting arms 4a, 4b, 4c, and 4d have a fixed length.

A recess 7 of an appropriate depth is formed in the outer end of the connecting arms 4a, 4b, 4c, and 4d inward from the side end, and a pin through hole 8 is formed in a direction crossing the recess 7. A connecting arm 5a of a connecting block body 2 or 3, which will be described later, is penetrated and drilled.
... or 6a... can be pinned by pins 9.

As shown in FIG. 2, the connecting block body 2 has a lower front shape with connecting arms 5a, 5b, and 5c projecting from the same body on three sides, and the sides of the linear connecting arms 5a, 5c. The side end of the connecting arm 5b is formed so that the concave portion 10' into which the convex portion 16 of the auxiliary block body 14 is fitted is shaped inward and protrudes diagonally in the middle of the linear connecting arms 5a, 5c. In addition, protrusions 10 for fitting into the recesses 7 provided in the connecting arms 4a to 4d of the basic block body 1 are provided in a protruding manner on the same body.

A pin through hole 11 is formed through the convex portion 10 and the concave portion 10' in an intersecting direction so that the connecting arms can be connected to each other by the pin 9.

Further, as shown in FIG. 3, the connecting block body 3 has a T-shaped front shape, has connecting arms 6a, 6b, and 6c on three sides, and has auxiliary blocks at the side ends of the linear connecting arms 6a and 6C. The basic block body 1 is formed by recessing the concave portion 12' into which the convex portion 16 of the body 14 is fitted inward, and attaching the basic block body 1 to the side end of the connecting arm 6b protruding from the middle of the linear connecting arms 6a, 6c. connecting arm 4a of
A protrusion 12 for fitting into the recess 7 provided at 4d is protruded from the same body.

A pin through hole 13 is formed through the convex portion 12 and the concave portion 12' in an intersecting direction, so that the connecting arms can be connected to each other by the pin 9.

The auxiliary block body 14 has a rod shape as shown in FIGS. 4, 5, 6, etc., and has convex portions 16 protruding from both ends thereof.

The convex portions 16 are the recesses 7 provided in the connecting arms 4a to 4d of the basic block body 1 or the connecting arms 5a to 5 of the connecting blocks 2 and 3.
The pins are inserted into the recesses 10' and 12' provided in the holes 10' and 12' provided in the holes 10' and 12', respectively, and pin holes are formed therethrough in the intersecting directions.

The auxiliary professional body 14 is a connecting arm 4a between the basic block bodies 1 and 1.
~4d It is used to connect each other or to connect the connecting blocks 2 or 3.

As shown in FIG. 4, the corner block body 17 is formed into a front arrow shape and has connecting arms 19 at 19 on three sides.
b* 19c, orthogonal connecting arms 19a, 19
Connecting arms having recesses 20' and 20' formed at the side ends of c for fitting into the convex parts 16 of the auxiliary block body 14, respectively, and protruding from the corners of the orthogonal connecting arms 19a and 19c. By forming a protrusion 20 on the side end of 19b to fit into the recess 7 of the basic block body 1 and connecting it to the auxiliary block body 14 and the basic block body 1,
The peripheral corners of the legal frame should be constructed at right angles.

As shown in FIG. 5, FIG. 6, etc., the corner block 18 is hook-shaped in the front and forms connecting arms 21a and 21c.
Convex portions 22, 22 for fitting into the recesses 12' of the connecting block body 3 are formed on the side ends of each of the connecting arms, respectively, and by connecting to the connecting block body 3, the peripheral edge of the legal frame is formed. Make sure to build at right angles to the corners.

The recesses 20' and 20' of the connecting arms 19a and 19C of the corner block body 17 are provided with pin holes in the intersecting direction, and the protrusions 20 of the connecting arm 19b are also provided with pin holes in the intersecting direction. A pin passage hole is formed through the corner block body 18 in a direction that also intersects the convex portions 22 and 22 of the corner block body 18, so that it can be connected to the predetermined block body described above with a pin 9.

Next, we will explain the installation of each block body.
First, the slope 15 to be cut down is leveled, and the basic block body 1 is placed on the slope, and the basic block body 1 is
.

After connecting and arranging a plurality of basic block bodies 1 as described above, the connecting arm 4at 4 of the basic block body 1 is opened.
b, 4ct The connecting arm 5c or 6c of the connecting block body 2 or 3 is pinned to 4d, and the connecting arm 5a of the connecting block body 2 or 3 is open.

5b, 6a, and 6b are connected and pinned together by an auxiliary block body 14.

Then, the connecting arms 21at21c of the corner block body 18 or the connecting arms 19a, 19c of the corner block body 17 are connected between the open connecting arms 6a and 6d of the connecting block body 3 in the corner or between the auxiliary block bodies 14. , pin.

As a result, the peripheral edge of the legal frame is made in a straight line by the connecting block body 2 or 3 and the auxiliary block body 14, and the corners are made into right angles by the corner block bodies 17 and 18, so that the peripheral edge and corner of the legal frame are aligned. It can be constructed in any shape.

Incidentally, the auxiliary block body 14 may have any length depending on the construction form, and any length may be used.

In addition, the connecting block bodies 2 are used when the basic block bodies 1 are arranged in a diagonal lattice shape (see Fig. 4), and the connecting block bodies 3
is used when arranging in a normal grid (Figures 5 and 6).
(see figure).

Since the present invention is constructed as described above, by combining and connecting the basic block body, the connecting block body, the auxiliary block body, and the corner block body, it is possible to make the periphery of the frame flush and finish it in a straight line. At the same time, the corners can be finished at right angles.

Therefore, there is no need for a separate block to finish the peripheral edge flush as in the past, making it very economical and
Installation can be done easily.

In addition, by making the connected block body connected to the basic block body T-shaped or T-shaped, the patterns formed by the connection of the block bodies can be varied in various ways, and the combinations and connections thereof can be made freely depending on the slope. It is very convenient.

Since each block body is combined and connected by fitting into a concave portion and a convex portion to form a legal frame, each block body is closely arranged with no risk of creating a gap, and also prevents positional shift after being closely arranged. The risk of this happening is reduced.

Therefore, it has the advantage of being able to construct a firm legal frame with little risk of collapse, and the ability to accurately construct various patterns.
