Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a connecting block for a seawall.

(Prior art) A convex portion is provided in the center of one long side of a block which has a trapezoidal shape when viewed from the front with a flat bottom and both sides of the short side cut out diagonally from the top to the middle. An articulated block with reinforcing bar insertion holes horizontally penetrating the block from the protrusion to the other long side wall is placed along the complex undulating topography of the river surface.
A large number of blocks are laid so that the long side surfaces of the blocks are aligned with the water flow direction, and the convex portions are in contact with the flat long side surfaces of other blocks where no convex portions are provided.

A rod-shaped connecting block formed to be a little more than twice the length of the connecting block is placed in the appropriate position of the group of connecting blocks laid down in this way, and a through hole is made to pass through both sides of the long side of the connecting block. The blocks for revetment are laid by connecting the through holes provided in each articulated block, inserting reinforcing bars into the communicating holes, and welding the ends to other reinforcing bars.

(Problem to be solved by the invention) Since the long side surface of the connecting block where no protrusion is provided is in close contact with the flat side surface of the connecting block, it is difficult to weld the reinforcing bars at that close point. The sides of the blocks to be removed must be separated from each other, the reinforcing bars exposed and welded together, and the isolated blocks must be restored after welding.

(Means for solving the problem) Both corners of the top surface of the rod-shaped body are cut diagonally to form a mountain shape 1.
At the same time, bulging portions 2, 2 are integrally provided at approximately the center of both long side surfaces of the rod-shaped body in a continuous manner with the chevron 1, and the rod-shaped body is formed from the bulging portions 2, 2. Straight wall 3 whose width is reduced toward the bottom of both sides of the long side,
3 are connected in a row, and several through holes 4 are formed between the two bulges 2, 2, and the block is made from the chevron-shaped oblique side on one long side to the bulge 2, and near both ends of the block. By cutting out recesses 5, 5 for inserting fingers, each having an inverted triangular shape when viewed from the front, and forming the bottom surfaces of the recesses 5, 5 into an arcuate surface continuous with the through holes 4, 4, The reinforcing bars 6 for block binding exposed in the recesses 5, 5 can be welded without moving the blocks.

(Operations and Examples) Examples of the present invention will be described along with their operations based on the drawings.

As shown in FIGS. 1 to 4, a chevron 1 is formed by cutting off both corners of the top surface of the rod obliquely, and a chevron 1 is formed approximately at the center of both sides of the long side of the rod.
Trapezoidal bulges 2, 2 are integrally protruded continuously from the bulges 2, 2, and straight walls 3, 3 whose widths are reduced from the bulges 2, 2 to the lower portions of both long sides of the rod-shaped body are provided. In the connecting block 11 which is arranged in series and further has through holes 4, 4 extending between both the bulging parts 2, 2, from the chevron-shaped oblique side on one long side to the bulging part 2, there is a front view toward both ends thereof. Recesses 5, 5 each having an inverted triangular shape for inserting a finger are missing, and each recess 5
is formed in an arcuate surface continuous with the through holes 4, 4.

The connection block 11 formed in this way,
Both ends of one side of the long side of the main body 7, as shown in FIGS. 5 to 7, are made by flattening the bottom and cutting both sides of the short side obliquely from the middle to the top surface. FIG. 8 shows an articulated block 10 in which vertically elongated protrusions 8, 8 are protruded from each other, and a through hole 9 is bored horizontally through the main body 7 at an intermediate position between the protrusions 8, 8. Lay as shown.

That is, the desired number of articulated blocks 10... has the protrusions 8 protruding from one side surface abutted against the flat side surfaces of the other articulated blocks 10, and the longer sides of the articulated blocks 10 are flushed with running water. Connecting blocks 1 are placed in rows on the riverbed surface in the same direction, and are placed in a suitable number of rows of the connecting blocks 10 laid in several rows.
The long side of 1 is aligned with the water flow direction, and at this time, the two articulated blocks 10, 10
One of the protrusions 8 comes into contact with the bulge 2 of the connecting block 11, and the flat side surface of the other connecting block 10 comes into contact with the bulge 2 of the connecting block 11, and the recess of the connecting block 11 The flat side surface of the connecting block 10 or the bulging part 2 of another connecting block 11 without the recess 5 comes into contact with the bulging part 2 on the side where the recess 5 is not provided.

(Effects of the invention) Since the invention is constructed in this way, the parts where the bulges 2 of the connecting blocks 11 and 11' are in contact with each other, and the flat side surface of the articulating block 10 and the bulges 2
Since the end of the reinforcing bar 6 is exposed from the recess 5 at the location where the reinforcing bar 6 is in contact with the reinforcing bar 6, it can be easily welded to the end of another reinforcement reinforcing bar 6.

Therefore, there is no need for the time and effort of moving the blocks at the reinforcing bar welding point to maintain the spacing and restoring them after welding as in conventional work, and since the blocks are not moved, there is no risk of finger jamming. It is safe. Furthermore, since the recess 5 is formed in an inverted triangle shape and its bottom is formed into an arcuate surface continuous with the through hole 4 passing through the block, the two reinforcing bars 6, 6 exposed in the recess 5 Since the reinforcing bars naturally fit together at the bottom, it is possible to weld the reinforcing bars without making them stick to each other, which simplifies the work and allows for quick construction. Furthermore, since the recess 5 is provided on the oblique side of the block body and is tapered downward, the portion of the block main body that is removed by the recess 5 is minimized. Since it can be formed, it also has the effect of preventing damage such as cracks and shell splits from that location.

As described above, the present invention is a useful device that has a simple structure, is robust, and is easy to manufacture.
