Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a continuous block suitable for constructing gutter blocks in parallel on both sides of a road, retaining walls on both sides of a waterway, etc. .

[Conventional technology]

Conventional blocks of this type, for example, in the case of box culverts, have a structure in which bolt holes are provided that extend through the block body in the longitudinal direction for tightening the blocks together. When constructing using these blocks, after constructing each block, a plurality of blocks were tightened together with bolts or wires were tightened using hydraulic jacks or the like.

Furthermore, when constructing side gutters, etc., a flange portion was formed at the end of the block body, and bolts and nuts were used in bolt holes provided in the flange portion to integrate each block.

With this method, it takes time to tighten the bolts, dirt gets caught between the blocks during tightening, and because metal is used for fastening, corrosion due to oxidation occurs over the long term, reducing the tightening strength. The dot was hot. In addition, it takes time to align the ends of the blocks and make them stick together.
There was also the problem of a long construction period.

In order to solve such problems, the inventor of the present invention has provided an upwardly tapered surface 32 and a downwardly tapered surface 32 with complementary shapes on the upper part of one end face and the upper part of the other end face of the block main body 31, respectively, as shown in FIG. A tapered surface 33 is formed, and a connecting pin insertion taper hole 3 is formed on both tapered surfaces and at the bottom of both ends of the block body 31.
We have previously proposed a block having a structure in which 4, 35, and 36 are formed, and a construction method using the block (Japanese Patent Laid-Open No. 60-237288).

To briefly explain the construction method using this block, first, the block 31 having the above structure is installed on the foundation, and then the connecting pins 38 having tapered sides on both sides are installed in each of the tapered holes.
Then, the block main body 31 is lifted diagonally so that the connecting pin 38 protruding from the upwardly tapered surface 32 fits into the taper hole 35 formed in the downwardly tapered surface 33 of the end face of the next block to be installed adjacently. When the taper hole 35 is inserted into the block body 31, a crane or the like is operated to lower the other side of the block body 31. By repeating this work in sequence, the blocks are closely connected and construction is carried out.

[Problem that the invention attempts to solve]

When performing such construction, the block body 31
The downwardly tapered surface 33 of the next block is connected to the connecting pin 38 protruding from the upwardly tapered surface 32.
Since the construction is carried out so that the blocks are in contact with each other, in the state of the blocks shown in Figure 12, the construction must always proceed to the right.

When construction is to be carried out to the left, it is sufficient to reverse the direction of the block, but when the top is tapered, such as for road gutter blocks, or for L-shaped blocks for both walls of a waterway, If the same block has the same characteristics, it is not possible to switch between using the same block for rightward construction and leftward construction. Therefore, it is necessary to manufacture and store two types of blocks, one for right-hand construction and one for left-hand construction, which poses disadvantages in terms of block manufacturing and stock.

The present invention was devised in view of the problems with conventional blocks, and aims to provide a block that can be constructed in both left and right directions despite using blocks of the same shape. purpose.

[Means for solving problems]

In order to achieve the purpose, the connecting block of the present invention has a fitting convex having an upwardly tapered surface and a downwardly tapered surface of mutually complementary shapes on the upper part of one end face and the upper part of the other end face of the block body, respectively. and a fitting recess, and tapered holes for inserting connecting pins having tapered ends at both ends are formed on both tapered surfaces of each fitting protrusion and fitting recess, and at the lower part of both ends of the block body. do.

〔Example〕

Next, the present invention will be specifically explained based on examples.

The embodiments shown in FIGS. 1 to 4 are a side view, a front view, a plan view, and a perspective view, respectively, showing a series of blocks for constructing a wall surface.

As shown in FIGS. 1 and 3, this interlocking block is provided with a fitting convex portion 3 on the upper part of the right end surface 2 of the block body 1, and a fitting recess 5 on the upper part of the first end surface 4. has been established. In this example, the fitting convex portion 3 provided on the end surface 2 has a cross section formed in a horizontally trapezoidal shape by an upwardly inclined surface, a vertical surface, and a downwardly inclined surface. An upwardly facing tapered hole 6 for inserting a connecting pin is formed on the upwardly facing inclined surface, and a downwardly facing tapered hole 7 for inserting a connecting pin is formed on the downwardly facing inclined surface.

The fitting recess 5 provided on the other end surface 4 is provided at the same height as the fitting protrusion 3 and has a shape complementary to the fitting protrusion 3 . A downwardly tapered hole 7 is formed on the downwardly inclined surface of the recess 5, and an upwardly tapered hole 6 is formed on the upwardly inclined surface.

Laterally tapered holes 8 are provided in the lower portions of both end faces of the block body 1, respectively. These tapered holes 6, 7, and 8 have the same shape, and can be inserted with half of the connecting pin 9 having tapered ends projected as shown in FIG. 6.

Next, a construction method using the continuous installation blocks of the present invention will be explained.

As shown in FIG. 5, the connecting block of the present invention is installed on the foundation 10. When constructing the connecting block in the right direction when facing the drawing, the upwardly tapered hole 6 in the fitting convex portion 3 of the connecting block should be
Then, insert the connecting pin 9 shown in FIG. 6 so that half of the connecting pin 9 protrudes upward. In addition, the horizontally tapered hole 8 on the lower surface of the connecting block has the above-mentioned connecting pin 9.
Let it stick out sideways. Next, the right-side connecting block is brought close to the installed connecting blocks while being suspended by a crane or the like. Then, it is operated so that the tapered hole 7 of the fitting recess 5 of the connecting block brought close to the connecting pin 9 projecting upward from the fitting convex portion 3 is fitted. At this time,
Tapered hole 8 at the bottom of the end face of the installed continuous block
The connecting pins 9 are inserted into the tapered holes 8 on the end faces of the blocks adjacent to the connecting pins 9, so that the end faces of the connecting blocks are placed in contact with each other. By repeating this procedure, the construction of the continuous blocks can proceed in the right direction in FIG.

Similarly, in FIG. 5, in order to perform construction in the left direction of the drawing with respect to the connecting block installed on the foundation 10, it is necessary to taper the fitting recess 5 of the installed connecting block upward. The connecting pin 9 projected upward from the hole 7 is fitted into the downwardly tapered hole 7 of the fitting convex portion 3 of the adjacent block for connection on the left. Then, the connecting pin 9 protruding sideways from the tapered hole 8 at the bottom of the other end of the installed connecting block is inserted into the taper hole 8 of the adjacent block, and the end surfaces of the blocks are placed in contact with each other. However, the construction of the block can proceed to the left.

2 is an end surface, 13 is a fitting convex portion provided on the end surface 12 side,
14 is the other end surface, 15 is a fitting recess provided in the upper part of the end surface 14, 16 and 17 are tapered holes provided in the fitting protrusion 13 and the fitting recess 15, 18 is the end surface 12,
14 is a horizontally tapered hole provided at the bottom, 19 is a connecting pin, and 20 is a foundation. Also, in the figure a, b,
C is a hanging fixture fixed to the block body 11.

The continuous installation blocks of this embodiment can be constructed in both directions, as shown in FIG. 9, in the same manner as the method described above, by virtue of the two continuous blocks formed in the center.

In this way, the connecting blocks of the present invention can be installed in any direction, so when constructing a culvert, for example, one unit of connecting blocks can be installed on both sides of a ditch, as shown in Figure 10. The crane can move in the direction of the arrow or in the opposite direction at the same time.

The connecting block shown in FIG. 11 is a gutter block having a water passage portion 30 communicating in the axial direction.
In this embodiment, one end surface 22 of the block body 21 is
Two fitting protrusions 23 are provided symmetrically on the upper part of the holder, and an upward tapered hole 26 and a downward tapered hole 27 are provided therein. The above two types of tapered holes are also provided in the fitting recess 25 at the upper part of the other end surface 24.

Furthermore, two laterally tapered holes 28 are symmetrically provided in the lower portions of the end surfaces 22 and 24. Therefore, in the same way as described above, the blocks for continuous installation can be constructed from either of the two directions.

In the above embodiments, the fitting convex portion and the fitting recess are formed into a trapezoidal shape with a rectangular cross section, but are not limited to this, and may be semi-cylindrical, hemispherical, or semi-cylindrical.
It can be of any shape such as a triangle.

[Effect of idea]

As explained above, in the connecting block of the present invention, a fitting convex portion and a fitting concave portion each having an upwardly tapered surface and a downwardly tapered surface that are complementary to each other are provided on both end surfaces of the block main body. A tapered hole for inserting a connecting pin is formed on both tapered surfaces. Therefore, during construction, it is necessary to select whether to insert the connecting pin into the tapered hole at the top of the fitting convex part or into the tapered hole at the bottom of the fitting concave part, and to insert the connecting pin into the tapered hole at the bottom of the fitting concave part. Continuous construction can also be carried out in the direction of . Moreover, even in construction where blocks such as underdrains are arranged symmetrically, construction can be easily and efficiently carried out in a predetermined direction.
