DETAILED DESCRIPTION OF THE INVENTION
The boundary block construction method and boundary block suspension apparatus according to the present invention will be described below with reference to the drawings.
[0005]
First, the side groove block 1 is a side groove block 1 having a slit 3 provided on the upper surface portion 2 thereof, and the side groove block 1 with slits is usually formed in a substantially rectangular parallelepiped prism shape.
[0006]
In the axial direction, for example, a hollow path having a vertically elliptical shape and having an inner upper wall formed in a flat surface is provided.
[0007]
Here, a slit 3 that communicates the hollow path and the outside is provided on the upper surface portion 2 so as to extend linearly in the axial direction, and the slit 3 extends from the center in the width direction of the side groove block 1. It is biased to one side.
[0008]
Furthermore, the outer surface of the upper surface portion 4 may be formed with a slight step with the slit 3 as a boundary.
[0009]
Next, reference numeral 4 denotes a boundary block.
[0010]
As is understood from the figure, the boundary block 4 is formed as a substantially trapezoidal rectangular body, and is disposed on one side in the width direction with the slit 3 of the slit side groove block 1 as a boundary. It is used as a ridge block for boundary with other sections. Although the boundary block 4 having a relatively short length is shown in the drawing, there may be a boundary block 4 having a long length, such as the side groove block 1, for example.
[0011]
Thus, the present invention is particularly effective for installing a long and heavy boundary block 4.
Reference numeral 5 denotes a hanger, and the hanger 5 has a pressing member 6 and a pair of holding members 7 and 7 attached with the pressing member 6 interposed therebetween, and is configured as a pinch-type hanger that can be expanded. Is done.
[0012]
Here, the pressing member 6 has a lifting hook portion 8 at the upper portion thereof, a rotating portion 9 is provided at a position substantially above the middle portion, and a lower portion is engaged with the surface side wall 10 of the boundary block 4 to be lifted. It has a presser plate type locking portion 11 to be stopped.
[0013]
Next, the pair of holding members 7 and 7 are attached so as to sandwich the pressing member 6 from both sides, and are pivotally supported by the rotating portion 9 of the pressing member 6 at the tip side (upper side). A shaft support portion 12 is provided, and the pressing member 6 and the pair of holding members 7 and 7 can be rotated with the rotation portion 9 and the shaft support portion 12 as fulcrums.
[0014]
Further, the rear end side (lower side) is configured to have a locking rod 15 inserted into a locking hole 14 provided at a substantially central position on the lower side in the longitudinal direction of the back side wall 13 of the boundary block 4 to be lifted. Yes.
As described above, the pressing member 6 and the pair of holding members 7 and 7 are rotated about the rotating portion 9 and the shaft supporting portion 12 as shown in FIG. 4 so that the boundary block 1 can be clamped.
[0015]
The method for laying the boundary block 4 will be described above.
[0016]
First, the side groove block with slits 1 is laid while being sequentially connected in the longitudinal direction, and a drainage channel is formed on the end side in the road surface width direction.
[0017]
Next, in order to use the slit 3 of the laid slit side groove block 1 for positioning, a positioning member 16 is inserted into the slit 3 as shown in FIG. The positioning member 16 may be a simple piece of wood.
[0018]
Thereafter, the boundary block 4 is clamped by the hanger 5 (see FIG. 4).
[0019]
That is, as described above, the locking rod 15 projecting from the holding members 7 and 7 is inserted into the locking hole 14 provided in the back side wall 13 of the boundary block 4, and the pressing member 6 is inserted into the front side wall 10. The locking portion 11 is locked and lifted upward from the state.
[0020]
Reference numeral 18 denotes an upper surface pressing piece. If the upper surface of the boundary block 4 is pressed by the upper surface pressing piece 18, the upper surface pressing piece 18 does not swing to the left and right sides of the boundary block 4. And this upper surface pressing piece 18 should just cut | disconnect and use L-shaped steel.
[0021]
And it is lowered and installed on the upper surface of the slit side groove block 1 to be installed. At this time, the positioning member 11 is brought into contact with the surface side wall 10 of the boundary block for positioning, and the slit side groove block 1 is installed. Install on top (see Figure 2).
[0022]
Thus, after installing the boundary block 4 to be installed first, the next boundary block 4 is sequentially lifted by the lifting tool 5 and installed while being connected as understood from FIG.
[0023]
Note that a predetermined interval is provided between the connection surfaces of the boundary block 4 in order to fill a predetermined joint material.
[0024]
Therefore, as shown in FIG. 3, the interval holder 17 is installed on the connection side upper surface of the existing boundary block 4. Thus, the next boundary block 4 is set with a predetermined interval.
[0025]
Thus, the boundary blocks 4 are sequentially installed as shown in FIG. 3, and finally used as boundary ridge blocks between the roadway and other sections such as sidewalks.
[0026]
As described above, according to the present invention, the boundary block 4 can be installed on the side groove block 1 with the slit safely, smoothly and efficiently.
【The invention's effect】
Thus, the present invention has the above configuration.
[0027]
If the boundary block construction method and the boundary block suspension device according to the present invention are used, the boundary block can be transported and lifted, and the construction can be performed quickly, surely, and at a low construction cost. This has an excellent effect that it can be quickly and surely performed by the lifting tool and can be provided at a low manufacturing cost.
