This is a method of widening the ground cover, and before covering the face plate of the road bridge widening unit, the electric circuit tube is installed in the notched portion of the base plate reinforcing rib provided inside the road bridge widening unit. Place and wire.

  Specifically, (1) the road bridge land cover widening unit is attached to the floor slab in a row in a row along the floor slab side edge of the road bridge without covering the face plate; (2) Next, an electric circuit pipe is arranged and wired in a notched portion of a base plate reinforcing rib provided in the road bridge cover widening unit, and (3) the road bridge cover widening is then performed. A continuous curb is formed by covering the face plate of the unit. Both the road bridge widening unit at the position where the lighting is desired and the road bridge widening unit connected to one or both ends of the road bridge are wired inside, and then the face plate is installed.

  In the present embodiment, the road bridge cover widening unit 1 '(electric pole unit) of the above-described second embodiment is installed as a road bridge cover widening unit at a position where lighting is desired, and the road bridge cover widening is performed. When installing the above-mentioned road bridge cover widening unit 1 (standard unit) of Example 1 as a road bridge cover widening unit connected to one end or both ends of the unit 1 ′, first, the road bridge cover widening unit 1 and the road bridge widening unit 1 ′ are arranged in a row in series along the edge of the road slab without attaching the face plates 2, 2 ′, and attached with bolts. An electric circuit tube is disposed in a notched portion of the reinforcing rib, that is, in the notched portion 81, and is wired from the through hole 52 of the road bridge widening unit 1 ′ to the outside of the rear side plate 5 ′, Become face Forming the curb portion 10 continuous covered the over preparative 2,2'. After covering the face plate 2 ′, the electric circuit tube wired outside the back side plate 5 ′ is wired from the electric circuit tube insertion hole 253 to the upper surface of the support plate portion 25.

  For example, the road bridge land cover widening unit 1 ′ (electric pole unit) of the second embodiment is arranged at one end, and a plurality of road bridge land cover widening units 1 (standard unit) of the first embodiment are connected to this. Further, the road bridge cover widening unit 1 ′ (electric pole unit) of the second embodiment is connected and arranged, and further, the road bridge cover widening unit 1 (standard unit) of the plurality of first embodiments is connected. Therefore, road widening and lighting wiring can be performed at a time.

  When the electric pipe is passed through the road bridge ground covering widening units 1 and 1 ′, which are installed in a column by standing up a hollow column of lighting on the electric pipe insertion hole 253, the power source of the bridge (end) of the road bridge From the section to the lighting, the electric circuit tube can be wired without being exposed to external wind and rain.

  The road bridge land cover widening units 1 and 1 ′ are both installed by attaching the base plate 3 on the concrete slab side end. Cover the two side edges of the concrete floor slab on the bottom surface of the base plate 3 and the front surface of the abdomen plate folding surface 67, and fix the road bridge cover widening unit 1, 1 'to the concrete floor slab with bolts. To do. Asphalt is paved on the extending portion of the base plate 3 so as to cover the anchor bar 35.

  According to the road bridge cover widening method of the present embodiment, both the road bridge cover widening unit (electric pole unit) and the road bridge cover widening unit (standard unit) are passed through the electric path pipe while being covered with the face plate. In addition, it is possible to pass the lighting up to the lighting installed on the upper part of the road bridge land cover widening unit (electric pole unit) without exposing the electric pipe. Further, when installing the road bridge widening unit, the electric circuit tube can be wired and accommodated before the face plate is covered. Therefore, since the wiring of the electric circuit pipe can also be performed when the unit is installed, the electric wiring of the electric circuit pipe and the widening of the road can be performed simultaneously. Therefore, the electric pipe can be prevented from being exposed to wind and rain, and the road can be widened, the wiring work can be made more efficient, and the construction period can be shortened.

  The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the invention. In addition, the constituent elements of the above embodiments can be arbitrarily combined without departing from the spirit of the invention.
