摘要： PROBLEM TO BE SOLVED: To provide a composite floor slab constructing method which enables the temporary application of composite floor slab without adversely affecting concrete under curing, and is excellent in cost efficiency, and to provide a curing board for use in the method.
SOLUTION: The composite panel is formed of floor slab panels 2 as steel shells and concrete portions 4a, 4b filled between the floor slab panels 2. During the curing of the uncured concrete portion 4a filled between the floor slab panels 2, the curing board 1 having necessary rigidity is set on the upper surface of the floor slab panel 2, and therefore the concrete 4a is continuously cured while the curing board 1 is in a temporary service.

摘要： PROBLEM TO BE SOLVED: To provide a composite steel-concrete floor slab which is constituted by juxtaposing trussed bars for shear reinforcement on a bottom steel plate, can effectively reinforce a slit of the bottom steel plate on a main girder without the dense juxtaposition of the trussed bars, and can reduce a material cost and a machining cost.
SOLUTION: In a floor slab panel 2 which comprises the bottom steel plate 3 installed on the main girder 1 and the plurality of juxtaposed trussed bars 4, a slit 11 with a width smaller than the flange width of the main girder is provided in a connection portion between the main girder 1 and the bottom steel plate 3 so as to prevent the displacement of the top surface of the main girder; the trussed bar 12 which continues astride the slit 11 and has a length set by adding an extra length required for the connection of a reinforcing material and the bottom steel plate to the width of the slit is arranged between the respective trussed bars 4 in parallel with the trussed bars 4, and fixed on the top surfaces of the bottom steel plates 3 on both the sides while sandwiching the slit between; and an area in which the floor slab undergoes negative bending moment with the slit sandwiched between is reinforced.

摘要： PROBLEM TO BE SOLVED: To provide a filling method excellent in local workability and capable of securely infilling highly-flowable concrete into a steel shell without forming unfilled parts.
SOLUTION: A steel shell b is constituted of a bottom steel plate 3, a plurality of shape steels 2 arranged in parallel at prescribed intervals at the upper face of the bottom steel plate 3, upper steel plates 1 put over on the shape steels 2, and partitions 5 as end plates. One filling unit a is constituted of a plurality of cells including a cell formed with a concrete casting opening 6 and a cell formed with a concrete discharge opening 7. Cells in the filling unit a are connected though by an opening 8 formed in the shape steel 2. The concrete casting opening 6 is connected to a hose 9 from a concrete pump car and highly-flowable concrete is poured into the filling unit a by the pressure of the pump. Overflowed concrete from the discharge opening 7 is put in a bucket or the like or the other infilling unit of the steel shell b.

摘要： PROBLEM TO BE SOLVED: To provide a composite floor slab having high rigidity of a steel shell panel state, endurable against a heavy machinery load in construction, capable of securing sufficient rigidity even in an overhang part, capable of coping even with supposed any large main girder interval, and capable of realizing high fatigue durability, in the sandwich type composite floor slab.
SOLUTION: This composite floor slab 1 is composed of a steel shell panel composed of an upper steel plate 2, a lower steel plate 3 and H shape steel 4 arranged between these upper-lower steel plates and connecting the upper-lower steel plates. The H shape steel 4 is arranged in a plurality at a predetermined interval in the bridge axis direction in parallel to the direction orthogonal to the bridge axis direction. A lower flange 4b of the H shape steel 4 and the lower steel plate 3 are joined by welding, and an upper flange 4a of the H shape steel 4 and the upper steel plate 2 are joined by frictional joining of a high strength bolt.

摘要： PROBLEM TO BE SOLVED: To provide a construction method for a composite floor panel enabling the joining work of a floor panel from a lower face for conventional work from a bridge face, to solve problems of traffic regulations and the prolongation of a construction term.
SOLUTION: The floor system panel constituting the composite floor panel is composed of an upper steel plate 1, a plurality of section steels 2 arranged in parallel at required intervals on the lower face of the upper steel plate 1, and a bottom steel plate 3 connecting the section steels 2 to one another to cope with a short-term traffic load by only a steel hull. A plurality of bolt holes 9 are formed in a joint plate 5 at the end of the floor system panel in advance. A bolt 6 is attached to the bolt hole 9 from an opening formed on the bottom face side of the floor panel on a main girder 15 supporting the end of the floor system panel and is tightened with a nut to join the floor panels. Then, a haunch member 4 is attached between the upper part of the main girder 15 and the bottom steel plate 3 of the floor panel from below to block the opening, and a filler is filled into the floor panel.
