Description
BACKGROUND OF THE INVENTION
In the ordinary overhead roads, the shoulders of the roads are
provided with guardrails or fences to prevent automobiles from
running off the roads, and the centaral portions of the roads are
provided with central reserves to check the running over of the
automobiles.
Further, in these roads, drainages are also provided to discharge
water on the roads therethrough, at a great deal of costs and time,
because if water remains on the road, it is very dangerous for the
automobile traffic.
Therefore, the labour, time and costs for such facilities are
indispensable for the construction of the road, and further the
available area of the road is somewhat restricted by the provision
for such drainage.
Accordingly, the object of the present invention is to provide a
novel construction unit which can be used as the curb for the road
as well as the drainage for the road with a compact and simple
structure.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to the drawings, the detailed explanation of the unit
of the present invention will be given in the following.
The first embodiment of the unit of the invention is shown in FIGS.
1 and 2. The front face of the upper portion of the unit is formed
a projected portion which is used for the curb (kurb) of the road
to receive the tire of an automobile, and the front face of the
lower half of the unit is also projected to form a drain
portion.
In the drawing, the numeral 1 denoted the unit of the invention
consisting of a hollow body, the front face of the upper portion of
the unit 1 is projected to form a curb portion 1, and the front
face of the lower portion of the unit 1 is also projected to form a
drain portion 3 which is used as the passage for the gathered
water. On the upper horizontal surface of said drain portion 3 and
on the continued vertical wall, a water grating 4 is provided, and
reinforcing plates 5 fitted in said curb portion 2.
The one end of this unit 1 is provided with a joint 6 to
interconnect with the end of another unit.
The unit 1 having the above described structure, in case it is made
of metal, is provided with anchor rods 9, 9 on its back side wall 7
and the bottom 8.
A plurality of these units can be aligned on a straight line as
shown in FIG. 13 by connecting the ends of the units with each
other by means of the joints 6.
As shown in FIG. 13, thus constructed unit 1 can be fixed to the
iron frame 62 of the overhead road 61, wherein the anchor rods 9
are welded tightly to the frame 62.
Referring to FIGS. 3 and 4, the second embodiment of the unit of
the invention will be explained in the following.
In place of the projected curb portion 2 of the first embodiment,
an inclined surface is formed on the front upper portion of the
unit to serve as a curb for the road receiving the tire of an
automobile and the lower half of the unit is used as the drain
portion of the unit.
The numeral 11 indicates a hollow body for the unit as similar as
that in the first embodiment, the front face of the upper portion
of the unit 11 is provided with an inclined surface 12 to serve as
the curb for the road, and the lower half of the unit 11.
Reinforcing plates 15 are fixed into the upper of the unit 11 and a
joint 16 is provided at one end of the unit 11 to connect the end
of another unit with each other.
In case this unit 11 is made of metal, anchor rods 19, 19 are
welded onto the back side wall 17 and the bottom 18,
respectively.
This unit can be aligned to form a long connection by the same
method as that in the preceding first embodiment and also it can be
installed to the overhead road 61 by being anchored to the iron
frame 62.
Next, the third embodiment of the unit of the invention will be
explained in accordance with FIGS. 5, 6 and 7.
This unit is used as an intermediate unit between the units of the
second embodiment, which serves as a curb and as water gathering
unit.
The numeral 21 indicates a unit consisting of a hollow body, an
inclined surface 22 is formed on the upper portion of the unit 21
which serves as the curb of the road, and the lower half of the
unit 21 is used as the drain portion 23.
The numerals 30, 30 are the folded portions of the curb portion 32
which are supported by the supports 30', 30' being fixed on the
inside of the drain portion 33. Thus fitting the folded portions
30, 30 into the supports 30', 30', the curb portion 32 can be
incorporated in one body with the drain portion 33.
The fifth embodiment of the unit is shown in FIG. 9, in which the
curb portion and the drain portion with the similar configurations
as those of the second embodiment, are made detachable.
The numeral 41 is a unit consisting of a curb portion 42 and a
drain portion 43, and the former curb portion 42 can be easily
removed from the latter drain portion 43. Plugs 40, 40 are provided
on the underside of the periphery of the curb portion 42, which are
received into the sockets 40', 40' being fixed on the inside wall
of the drain portion 43 to form one integral body.
Thus constructed units of the fourth and fifth embodiments can be
connected with each other in great numbers in similar manner as
those of the first, second and third embodiments, further they can
be fitted to the overhead roads.
In the drawings, the numerals 35 and 45 are reinforcing plates, 37
and 47 are back side walls of the units, 38 and 48 are the bottoms
of the units, and 39, 39, 49, and 49 are all anchor rods.
Though the grating and joint are not shown in FIGS. 8 and 9, they
may be provided to the units, of course.
The curb and drain unit of the present invention as shown in the
above as first to fifth embodiments can be installed on the
shoulders and/or central reserves of the roads, thereby preventing
the automobile from running off the road and discharging water from
the road through the grating into the drain portion of the aligned
units.
The next embodiment as shown in FIG. 10, 11 and 12 is an expansion
joint, which is used at the expansion joint of a bridge etc.
The numeral 50 is a rubber made joint which consists of margins 51,
51 and a joint body 52. The joint body 52 has front margins 53,
bottom margins 54, rear margins 55 and bellows 56, 57 and 58, and
when it is observed from the side, the configuration of the joint
50 is like a fish hook as shown in FIG. 11. The rubber joint 50
having such structure can be fitted to, for example, the unit 31 in
the manner as shown in FIG. 14, wherein the margins 53, 54 and 55
are adhered onto the outer sides of the front, bottom and rear side
surfaces of the curb and drain unit 31. The units shown in FIG. 14
are of the fourth embodiment, however without saying, the units may
be those of other embodiments, such as first, second, third and
fifth ones.
This rubber joint 50 is conveniently employed for bridges, however,
it can be used also for the waterway through a rice-field.
When this joint is used, the water in the drain passage of the unit
is never caused to leak.
As explained in the above, the curb and drain unit of the present
invention using a hollow body which consists of the upper curb
portion and the lower drain portion, can be fitted to the both
sides or on the central reserve of the road, and serves as the curb
for the road to prevent the automobile from running off the road,
and at the same time, serves as the drain to discharge the water on
the road, therefore the traffic safety of the road, even on a rainy
day, can be enhanced. Further, the unit of the present invention
can be used for a road passing through a tunnel. And further, the
unit of the present invention can be made of synthetic plastics,
and the unit can be fitted to the road without using the anchor
rods only by the drain portion being buried in the road.
It should be emphasized, however, that the specific embodiments
described and shown herein are intended as merely illustrative and
in no way restrictive of the invention.
