Description

[Detailed description of the invention] - Industrial field of application - This invention is designed to prevent blocks from shifting when stacking blocks and creating unevenness on the constructed retaining wall surface. This relates to a slip stopper.

-Prior art and problems- The stacking blocks 21 without backing plates as shown in Fig. 6 were stacked one by one by hardening with mortar, but in order to shorten the construction period, the backing plates 6 were A construction method has come to be used in which blocks 5, . When filling the void 22 with mortar, mortar is poured into the void 22 and then a rod-shaped vibrator is inserted to spread the mortar so that no voids are formed. Since the retaining wall is simply placed on the retaining wall, it may shift when vibrated with a vibrator, causing unevenness on the constructed retaining wall surface, making it unsightly. In particular, when the slope of the retaining wall to be constructed is steep, the blocks 5 are likely to shift, making it extremely difficult to construct a retaining wall without unevenness.

Therefore, in order to prevent the blocks 5 stacked empty from shifting, male and female unevenness is formed on the end face 7 of the blocks, which is the stacking surface, and the blocks are stacked while making the unevenness fit together. In order to be able to construct a curved retaining wall, it is necessary to provide a certain amount of play (usually about 5 mm) in the fitting of the unevenness formed on the block 5, and therefore, this fitting is not effective in preventing the block 5 from falling. However, there was a problem that it was insufficient to prevent the block 5 from slipping. Moreover, in the case where the end surface 7 of the block is provided with unevenness,
There is also the disadvantage that the shape of the formwork for forming the blocks 5 is complicated, and the construction is complicated because the directions of the blocks 5 must be aligned one by one when stacking them.

-Purpose of the invention- The purpose of this invention is to solve the above problems and provide a technical means that can reliably prevent the blocks stacked empty from shifting. It is an object of the present invention to provide a slip stopper that can reliably prevent the slippage of empty stacked blocks by mounting the block and is easy to manufacture and install.

- Means for Achieving the Object - Explaining using the reference numerals of the illustrated embodiments, the stacking block shift preventers 12, 17 of this invention prevent stacked blocks 5...5, 9...9 from being adjacent to each other. A thin plate-like main body 1, 13 is inserted between the end faces 7, 11 to cross the end faces in the width direction, and the lower ends of the plate-like main body are spaced apart by the end face width dimension L of the block. Positioning protrusions 2, 3, 14, and 15 are formed to protrude, and locking protrusions 4 and 16 are formed to protrude from at least one end of the upper surface of the plate-like main body.

-Operation- Slip stoppers 12, 17 configured as above
As shown in FIG. 3, the blocks 5a and 5b are interposed between the end surfaces 7a and 7b of the retaining plates 6a and 6b of the blocks 5a and 5b that are stacked empty. For example, in the anti-slip tool 12 shown in FIG. 1, the anti-slip tool 12 is fitted to the upper end of the backing plate 6a of the lower block so that the backing plate 6a is sandwiched between the positioning protrusions 2 and 3, and the upper block 5b is held in place. They are stacked by positioning them using the locking protrusions 4 of the stoppers. Generally, retaining walls are constructed with a rearward inclination, so the upper blocks 5b tend to shift rearward (toward the retaining plate 6 side). Therefore, the slip stopper 12 is mounted so that the locking protrusion 4 comes into contact with the rear surface of the retaining plate 6b of the upper block. If the retaining wall is constructed approximately vertically and there is a risk that the block 5 may shift in either the front or back direction, a shift stopper with locking protrusions 16 provided at both ends of the plate-shaped main body 13 as shown in FIG. 17 should be used.
In the blocks 5...5 stacked empty in this way, the displacement of the upper block 5b is caused by the displacement stoppers 12, 1 fitted to the lower block 5a.
Since it is blocked by the locking protrusions 4 and 16 of No. 7, there is no risk of displacement during pouring of mortar, and no unevenness will occur on the surface of the retaining wall to be constructed.

-Embodiment- Fig. 1 shows a first embodiment of the slip stopper of this invention, which is formed by bending a metal plate. In the figure, 1 is a plate-shaped main body, 2 and 3 are positioning protrusions, and 4 is a locking protrusion. Positioning projections 2, 3
The locking projections 4 are formed by bending the ends of the plate-shaped main body 1, and the inner distance L between the positioning projections 2 and 3 is equal to the thickness L of the retaining plate 6 of the block 5. Further, the positioning protrusion 3 and the locking protrusion 4 are formed by bending the main body 1 at right angles, and the positioning protrusion 2 is bent at an angle matching the inclination angle of the retaining plate 6a of the block 5a shown in FIG. 5a in Figure 3,
5b is a stacking block, 6a and 6b are backing plates, and 7 is an end face of the backing plates 6a and 6b.

In the embodiment shown in FIG. 1, one of the positioning protrusions 2 is made narrow because, as shown in FIG. The width of the end surface 11 of the block backing plate 10 (the stacked state of the backing plate is shown by the broken line in FIG. 4) is tapered as shown in FIG. The width of the contacting positioning protrusion 2 is narrowed.

FIG. 2 shows a second embodiment of the anti-slip device of this invention, which is entirely integrally molded from synthetic resin. In the figure, 13 is a plate-shaped main body, 14 and 15 are positioning protrusions, and 16...16 are locking protrusions.
It is provided at both ends of 3. In this way, the locking protrusion 16
If the blocks are provided on both sides, it is possible to prevent the stacked blocks from shifting in the front-back direction, which is convenient when the blocks 5 and 9 are stacked substantially vertically.

-Effects of the invention- If blocks are stacked while interposing the shift stopper of this invention explained above between stacked blocks, the mutual displacement of empty stacked blocks is reliably prevented, and There is no risk of blocks shifting from each other when pouring mortar after stacking.
A retaining wall without unevenness can be easily constructed. After the blocks are fixed together with mortar, the anti-slip device is no longer necessary, but it is extremely cheap and the anti-slip device does not appear on the surface of the retaining wall, so it can be left as is. good. In addition, this shift stopper can be easily attached manually each time blocks are stacked, and by attaching this shift stopper, the position of the upper block when stacking blocks can be easily positioned. The overall work load when stacking blocks is further reduced.
