PURPOSE: To design a steel beam by compounding with a concrete floor board for reducing manufacturing cost. CONSTITUTION: In an adhering method between a concrete floor board and a steel beam, a plurality of recessed parts 5 is provided on the steel beam adhering face of the concrete floor board in parallel to each other at fixed spaces in the direction of a bridge axis, and after injecting adhesive agent 4 in each recessed part 5 into a bited-in state, an extended steel beam 2 is stuck to the steel beam sticking face of the concrete floor board 1 by the adhesive agent 4. The transmission of shearing force between the concrete and an adhesive agent layer is carried out through an irregular biting-in part composed by injecting the adhesive agent 4 into each recessed part 5 of the concrete floor board 1 without expecting strength on an adhesion interface between the concrete floor board 1 and the adhesive agent 4. Thus it is possible to compound the extended steel beam 2 with the concrete floor board 1 for designing the steel beam, and its manufacturing cost is thereby reduced. |
