って良好でない作業環境下で作業しなければならない事
態が生じ易い。As described above, the method of manufacturing the girder and the floor slab separately at the factory and integrating them at the site is as follows.
Since the on-site joining work for integrating the girder and the floor slab is indispensable on site, the number of on-site work is inevitably increased.

し易いなどの問題がある。In addition, when a vertical rib is attached to the lower surface of the deck plate, not only is it necessary to manufacture a complicated scar wrap, but also stress tends to concentrate on the intersection between the vertical rib and the horizontal girder, and fatigue tends to occur. There is. Further, there is a problem that cracks are easily generated on the asphalt pavement surface cast on the upper surface of the flat deck plate. Further, since the thermal conductivity of the steel material is large, there is a problem that the road surface is easily frozen and noise is easily generated.

一部を、予め、一体的に連結することができる。That is, the present invention is an RC composite steel slab girder bridge mainly composed of a girder, a slab and a pavement, wherein the slab is composed of a deck plate and a deck plate. It is an RC synthetic steel deck slab girder bridge formed by longitudinal ribs arranged on the upper surface. Further, according to the present invention, the beam and a part of the floor slab can be integrally connected in advance.

As shown in FIG. 2, the RC synthetic steel slab girder bridge 1 of the present invention is mainly cast on a slab 2, a pair of left and right main girders 3 joined to the slab 2 and the slab 2. The pavement portion 4 is formed.

As shown in FIG. 4, the floor slab 2 and the main girder 3 are integrally connected in advance at a factory. As shown in FIG. 1, the floor slab 2 of the second block B mainly includes a deck plate 5 and a number of vertical ribs 6 welded and fixed to the upper surface of the deck plate 5. In the figure, a number of main reinforcing bars 7 are fixed on the vertical ribs 6.
May be fixed on the vertical rib 6 on site if desired.
Further, the horizontal ribs 8 and the main girders 3
Are fixed by welding.

Is also formed in the same manner as the floor slab 2 of the second block B (see FIGS. 3 and 5). In addition, as shown in FIG.
The third blocks C on the left and right are connected to each other by a connection block D. Here, as the vertical rib, a rib having an L-shaped cross section is desirable, but for example, a flat plate, a valve-shaped rib, or a U-shaped rib may be used.

起因する疲労を回避することができる。As described above, according to the present invention, since the floor slab is formed of the deck plate and the vertical ribs provided on the upper surface of the deck plate, the production of a complicated scar wrap is eliminated. Production costs can be reduced. In addition, there is no intersection between the vertical ribs and the horizontal ribs, so that fatigue caused by stress concentration can be avoided.

の位置決めなどの役割を担っている。In addition, since the beam and a part of the floor slab are integrally connected in advance, there is no need for a site work for connecting the beam and the floor slab in the field, and the construction period can be shortened. Further, in the present invention, since the rigidity of the floor slab is increased,
Cracking of the pavement can be prevented. The vertical rib is a part of the effective cross section of the main girder, and plays a role of positioning the reinforcing member of the deck against dead load, the distribution reinforcing bar of the floor slab, and the main reinforcing bar.
