Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a corner connecting fitting of a slope block that connects connecting rings protruding from the corners of four slope blocks.

[0002]

[Prior art]

 The middle of the U-shaped connecting fitting is bent in parallel from the side to form a bent portion, which is first inserted into the connecting rings of the two slope blocks, and at the free end of the connecting fitting, the two plates of the plate are connected. Japanese Patent Publication No. 7-86215 discloses a corner connecting fitting of a slope block which is fitted with a nut through a through hole.

[0003]

[Problems to be solved by the device]

 This known connecting fitting has a drawback that it requires manufacturing cost because it is necessary to form a screw on each of the free ends of the connecting fitting and a plate having two through holes must be used. Moreover, when connecting the slope blocks, it is necessary to insert the through holes of the plate into both free ends of the connecting bracket and then screw the nuts into the screws protruding above the plate. However, there is a drawback that the construction cost is high due to the troublesome work and the construction of slopes for roads and rivers.

The present invention makes it possible to inexpensively manufacture a corner connecting fitting for a slope block of this type, and to easily connect the slope blocks.

[0005]

[Means for Solving the Problems]

 The corner connecting fitting of the slope block according to the present invention comprises a pair of arm portions whose front and rear ends are bent upwards, which are installed side by side at a predetermined interval and bridge the rear ends of the pair of arm portions. They are connected by a portion, a through hole is formed at the tip so as to face each other, a fastening bolt is passed through this, and a nut is screwed to the projecting end.

When connecting the corners of four slope blocks with this connecting fitting, a slope block is laid on the ground and the connecting rings of the reinforcing bars protruding from the reinforcing bars of the blocks to the outside of the corners are mutually connected. Butt, first insert the tips of the arms into the two connecting rings from the upper side to the lower side, then insert the tips into the other two connecting rings from the lower side to the upper side, and place them on the connecting rings. A fastening bolt is passed through the through hole at the protruding tip, and a nut is screwed into the protruding end.

[0007]

[Embodiment of device]

 The corner connecting fitting of the slope block of the present invention connects the connecting rings made of the reinforcing bars protruding from the corners of the four slope blocks as described above, and the pair of arms and the bridge are It is manufactured by punching iron plates into a connecting ring and then punching and bending them.

The pair of arms may be arcuate with both ends facing upward, or may be rectangular. Further, in order to increase the cross-sectional area of each part and increase the strength, it is preferable to use an iron plate of about 6 mm and to form a bulge at the tip of the arm to prevent the strength from being reduced by perforation.

It is preferable to use a commercially available product as the fastening bolt that connects the tips of the pair of arms, and to fasten the collar with a collar interposed between the tips of the arms.

[0010]

【Example】

 Next, an embodiment of the present invention will be described in detail with reference to the drawings. 1 and 2 are corner connecting fittings of a slope block of the present invention, in which the rear ends of a pair of arms 1 and 1 whose front and rear ends are bent upward are connected by a bridging part 2 and Is provided with bulging portions 3 and 3, through holes 4 and 4 are formed so as to face the bulging portions, and a collar 5 is interposed between the through holes 4 and 4 as shown in FIG. A fastening bolt 6 is inserted from the through hole 4 to the other through hole 4, and a nut 7 is screwed on the tip thereof.

As shown in FIG. 3, the arm portions 1 and 1 and the bridging portion 2 of the above-mentioned connecting metal fitting are formed by punching an iron plate having a thickness of 6 mm into a ring shape having a width of 11 mm, and further cutting a part of both sides. The bulging portions 3 and 3 are formed on the bulging portion, and the through holes 4 and 4 are formed in the bulging portion. The position opposite to the cutting part 8 is defined as a bridge part 2, and both sides of the bridge part 2 are bent downward to form arcuate arm parts 1, 1.

Reference numeral 9 in the figure is a slope block laid on the slope, and a plurality of concrete pseudo stones 10 are connected to each other by reinforcing bars 11 in a substantially rectangular shape, and connecting bars 12 made of reinforcing bars are projected from the four corners. There is.

As shown in FIG. 4, a large number of slope blocks 9 are laid on the slope, and as shown in FIGS. 5 and 6, among the four connecting rings 12 protruding from the corners of each slope block 9, First, the arm portions 1 and 1 are respectively inserted into the two adjacent connecting rings 12 from the upper side to the lower side, and then the tips thereof are inserted into the other two adjacent connecting rings 12 from the lower side to the upper side, respectively. If the fastening bolt 6 is inserted with the collar 5 sandwiched between the through holes 4 and 4 projecting upward, and the nut 7 is screwed to the projecting end and tightened tightly, the corners of each laid slope block 9 can be secured. Is connected to.

The slope block 9 in the above embodiment is made up of a plurality of pseudo stones 10 connected to each other by a reinforcing bar 11. However, a connecting ring made of a reinforcing bar is made to protrude from the four corners of one plate-shaped rectangular concrete block. The same is true for the blocks.

[0015]

[Effect of device]

 The slope block according to the present invention is implemented in the form described above, and has the effects described below.

The bridging part connecting the pair of arms and the rear end can be easily manufactured by punching, punching and bending an iron plate by press working, and only one fastening bolt is used. Therefore, the manufacturing cost can be reduced.

Each ring can be connected by inserting a pair of arm parts into the four connecting rings protruding from the corners of the slope block and connecting the ends with a single fastening bolt. Connection work is extremely easy, and construction costs such as road and river slope work can be significantly reduced.
