ている。Due to its economic efficiency and ease of construction, it is the most common structural type for bridges with medium and small spans. An example of such a structure is shown in Fig. 1, which shows a part of a cross section perpendicular to the direction of bridge construction. A composite girder is composed of a steel plate formwork such as a deck plate that is placed and fixed on the upper 7 langes 3 of the girder, and a concrete slab j that is cast on top of this steel plate formwork.
Main girder ko and concrete slab 5 are upper 7 rungs 3 of main girder 2.
They are integrated by studs 6, 6, . . . that protrude from the top.

不可とされていた。However, in the above configuration, due to the nature of concrete that cannot withstand tensile stress, a neutral axis for bending as a composite cross section must not exist in the concrete constituting the slab j. The girder height H of the main girder 2 has its own limit, and it was not applicable in cases where the girder height was restricted.

A reinforcing bar insertion hole is drilled in the longitudinal beam above the receiving plate, and a stud is provided to protrude, and the end of the steel plate form is placed and fixed on the receiving plate, and the reinforcing bar is inserted into the reinforcing bar insertion hole. It is characterized in that a deck slab is formed by assembling reinforcing bars and pouring concrete onto the steel plate formwork up to the upper surface of the main girder.

Pass the reinforcing bars 10 through the reinforcing bar insertion holes r of 2A in the longitudinal beam part of the concrete slab, and incorporate other reinforcing bars into the concrete. The concrete slab j is integrally connected via the reinforcing bars 10 that pass through the longitudinal beams 2A of the main girder 2, and the squad members, ribs, etc., and the main girder 1 and the reinforced concrete slab 5 form a composite girder. configured. In this case, since the lower surface of the concrete slab j is in contact with the steel plate formwork, will it be a problem if the concrete enters the multi-slight tensile region due to the neutral axis relationship? It won't happen.

大することができる浸れた効果がある。As explained above, in the composite girder structure of the present invention, a receiving plate (support) orthogonal to the longitudinal beam of the main girder made of steel having a cross-sectional shape or a similar shape is installed in the middle of the longitudinal beam. ,
A single reinforcing bar hole is drilled in the longitudinal beam above the receiving plate, and a stud is provided to protrude, and the end of the copper plate form is placed and fixed on the receiving plate, and a reinforcing bar is inserted into the reinforcing bar insertion hole. The reinforcing bars were inserted through the steel plate formwork and poured up to the upper surface of the concrete main girder to form the deck slab. The application of digits is now possible and has a submerged effect that can significantly expand the range of economical synthetic techniques.
