る。Therefore, the present invention provides a flat girder connected to a column and installed in parallel,
A ribbed slab with a large number of ribs arranged in parallel is integrally connected with the ribs perpendicular to each other, and prestress is introduced by passing a PC cable on both sides of a flat girder with a column in between.
以下、図示の実施例について説明する。The illustrated embodiment will be described below.

している。The ribbed slab 3 is formed to have a relatively thin thickness, and has a large number of ribs 4 arranged side by side on the lower surface, and these ribs are perpendicular to the flat girder 2, and their intervals are set at right angles. The width is about the same as that of the flat girder, and the lower surface is at the same level as the lower surface of the flat girder.

通したものである。Further, the PC cable 5.5 constitutes a flat cable, as shown in Figs. 4 and 5, and the flat cable is made of a flat sheath formed by winding a ribbon-shaped thin steel plate in a spiral manner and forming it flat. 51, and a plurality of stranded PC steel wires 52 are inserted into the flat sheath in a negative row.

定すればよい。Note that the PC cables 5, 5 have a flat sheath 51.
It is better to fill the void inside with cement paste to create a bond type. Also, instead of using a flat cable like this,
Round cables may be used in the same manner, and these may be selected appropriately taking into account the required strength, workability, and whiteness.

The stress properties against vertical and horizontal loads have been improved, making it possible to have sufficient mechanical strength, making it possible to reduce the thickness of the floor structure and lower the floor height of the building, making space more efficient. It is possible to rationalize the structure, shorten the construction period, and reduce the frame cost.
