On the other hand, as shown in FIG. 3, the weir wall cap 4 is made of an elongated plate made of extruded aluminum or its alloy and has a generally downward U-shaped cross section, with the outer hanging wall portion 4c extending from the inner hanging wall portion 4b. Raise the top plate part 4a
By sloping the roof gently so that the indoor side is lower, drainage is improved.

Also, the mounting base 2 is superimposed on the back side of the weir wall cap 4.
1 is formed by aluminum casting, which is an extruded mold material of aluminum or its alloy, as shown in Fig. 4, or by press working of iron or steel plate as shown in Fig. 9, which will be described later, and has a generally flat overall shape. The upper piece 21a is formed on a flat surface having the same slope as the top plate 4a of the weir wall cap 4, and reinforcing legs 21b are provided on both sides of the upper piece 21a. 21c is provided to protrude substantially downward in a U-shape, and therefore, the upper piece portion 21a is recessed in a concave shape relative to the reinforcing leg portions 21b and 21c. Note that there is a bolt insertion hole 21d in the center of the upper piece 21a.
A plurality of screw insertion holes 21e are formed through the periphery thereof.

Furthermore, the washer 22 superimposed on the back side of the upper piece 21a of the mounting base 21 is made of extruded aluminum or its alloy, aluminum casting, press working of iron or steel plate, or cut out of hard synthetic resin, as shown in FIG. It is formed by processing, etc., and the overall shape is a plate-like member that is thick at one end and thin towards the other end, and its upper surface 22a has the same slope as the upper piece 21a of the mounting base 21. The lower surface portion 22b is formed as a horizontal surface, and has a bolt insertion hole 22c in the center and a plurality of screw insertion holes 22d around the bolt insertion hole 22c.

The cylindrical support 2 is similarly formed from an extruded material of aluminum or its alloy, and has a plurality of bis pockets 2a, 2a, . It is set in.

Furthermore, as shown in FIG. 3, the handrail cap 1 is composed of an upper cap member 1a having a semicircular arc cross section, and a corresponding lower cap member 1b having a hollow bowl shape in cross section.
Both cap members 1a and 1b are formed with an engaging portion 1c and an engaged portion 1d for removably anastomosing each other, and a horizontal support wall 1e is formed on the lower cap member 1b.
are integrally formed.

Furthermore, the through bolt 5 is formed longer than the cylindrical support 2, and has a piece-shaped engagement hook 6 integrally formed at its lower end as shown in FIG.
l ₁ is the width la of the engagement groove insertion part 14a of the anchor fitting 7
The width l ₂ of the wider side is wider than the width la of the insertion portion, and the engagement groove engagement portion 14b
It is formed to be slightly narrower than the width lb, or the same, preferably slightly wider.

As shown in FIG. 3, the order of assembling the handrail is to fit the anchor fittings 7 across the top of the weir wall 3, and then insert the anchor bolts 17, which are provided through the weir wall 3 indoors and outdoors, on both sides of the anchor fittings 7. It is inserted into the mounting holes of the plate parts 7b and 7c and fixed by tightening the nut 18. By providing notches 16 in the engaging plate parts 7d and 7e as shown in FIG. 2, the tightening work can be performed without being hindered by the engaging plate parts 7d and 7e. Furthermore, by using the anchor bolt insertion parts 15, 15 provided on the top plate part 7a of the anchor fitting 7, as shown by the dashed line in FIG. It may also be driven into the wall 3 and fixed.

On the other hand, the lower cap member 1b of the handrail cap 1, the weir wall cap 4, the mounting base 21, and the washer 22 are attached to the upper and lower ends of the cylindrical column 2, respectively. Insert it slightly tighter than the through hole 1g provided in the wall 1f,
Although it is sufficient to simply press the support wall 1e against the support wall 1e, for example, as shown in FIG.
Semicircular arc-shaped holes 1h, 1h are provided at the abutting portions of b, 1b, respectively, thereby making it possible to easily form a circular through-hole 1g, into which the support column 2 is fitted, and the supporting wall is formed. By screwing the screw 10 from 1e into the bis pocket 2a inside the column, the lower cap member 1b can be attached to the upper end of the column 2, and the adjacent lower cap members 1b, 1 can be attached to the upper end of the column 2.
It can serve as a coupling means between b.

Also, attach a weir wall cap 4 to the lower end of the cylindrical support 2, a mounting base 21 to the back side of the cap, and a washer 22 to the back side of the mounting base, and insert the screw 11 into the washer 22 and the mounting base 21, respectively. Holes 22d, 21
e, and screw into the bis pocket 2a of the column 2 through the screw insertion hole (not shown) in the weir wall cap 4, and then insert the through bolt 5 into the cylindrical column 2 and attach the upper end thereof. Lower Kasagi member 1
The nut 9 is screwed into the supporting wall 1e of b, and the lower end is passed through the bolt insertion holes 21d and 21c of the mounting base 21 and the washer 22, and the engaging hook 6 is inserted into the back side of the washer 22. These are assembled in advance as a unit, and then, with the longitudinal direction of the engagement hook 6 aligned with the engagement groove 14 of the anchor fitting 7, this unit is assembled as shown in FIG. By placing the washer 22 so that the lower surface 22b is in contact with the pair of engaging protrusions 7f and 7g of the anchor fitting 7, and the reinforcing legs 21c and 21d are in contact with the anchor fitting 7, the engaging hook can be fixed. 6 from the insertion part 14a of the engagement groove 14 to the engagement part 14
b, rotate the through bolt 5 by about 90 degrees to engage the engagement hook 6 with the engagement groove 14, and then screw in the nut 9 to generate a pulling force to lower the lower cap member 1b, Cylindrical support 2, weir wall cap 4,
The mounting base 21, the washer 22, and the anchor fitting 7 are firmly pulled together and fixed to each other, and reinforced by the through bolt 5. In addition, the indoor and outdoor hanging walls 4b and 4c of the weir wall cap 4 have engaging protrusions 23 protruding from their lower ends.
are engaged with the engagement plate portions 7d, 7e of the anchor fitting 7, and the interior is kept watertight by seal gaskets 20, 20 attached to a bracket 21 screwed to the bracket 21 using both engagement protrusions 23. Ru.

And finally, the upper Kasagi member 1a of the handrail Kasagi 1
The handrail is completely attached to the weir wall by engaging the lower cap member 1b with the engaging portion 1c and the engaged portion 1d.

As shown in FIG. 9, the other structure is the same as that of the previous embodiment, but the mounting base 21' is formed by bending iron, steel plate, etc. to form an upper piece 21'a and reinforcing legs 21' on both sides thereof. b, 21'c may be formed integrally.

(Effects) According to the present invention, the handrail cap, cylindrical support, weir wall cap, mounting base, washer, and anchor metal fittings can be firmly fixed integrally with through bolts, and the fixing work of these can be done easily. Since it is only necessary to tighten the through bolts on the handrail cap side, the work is very easy and can be done quickly.

In particular, according to the present invention, on the back side of the weir wall cap and the mount that reinforces the weir wall, the cap has an upper surface with the same slope as the top plate of the mount, and a horizontal lower surface perpendicular to the cylindrical support. Since the washer with the cylindrical support is attached and screwed from the lower surface to the bis pocket of the cylindrical support, the screw can be screwed perpendicularly to the bis pocket of the cylindrical support. As a result, it can be accurately installed perpendicularly to the anchor fitting. On the other hand, if the above-mentioned washer is not available, by screwing the screw into the bis pocket of the cylindrical support, the cylindrical support will be inclined by the slope of the top plate of the weir wall cap. It is necessary to forcefully screw the screw into the bis pocket so that the column remains perpendicular to the anchor fitting.

Furthermore, according to the present invention, even if the drainage slope of the top plate of the weir wall cap varies, it is only necessary to insert a washer having a sloped top surface that matches the slope, so manufacturing is easy. It's practical.
