As a structural type for high-rise buildings, steel structures or steel-framed reinforced concrete structures with excellent durability and earthquake resistance are mainly adopted. In these high-rise buildings, flat or corrugated deck plates are used in the floor slab system due to the need to shorten construction period and reduce labor costs. It is common to use, and products that integrate a truss girder made in the form of a truss and a flat type deck (flat flat deck), or products that integrate a truss girder and a corrugated deck plate have been developed.

However, in general, corrugated decks have structural problems or paste leakage due to excessive deformation of the connection between deck plates due to workers stepping on the connection between deck plates, construction materials being loaded on the connection, or the self-weight of the poured concrete. Alternatively, because construction quality problems such as water leakage appeared, a rib-shaped deck with a closed end was manufactured and used.

However, in the case of a corrugated deck with the ends closed in this way, when the corrugated deck is mounted on the steel beam of which the tie bar is made, there is a risk of it falling off due to instability due to interference by the tie bar, and leakage of paste from the end of the corrugated deck. Or there was a problem such as water leakage.

In general, when connecting deck plates, a rib-shaped deck plate is made by connecting the ends that protrude in a cantilever shape from the upper part of the valley. Therefore, the connection part is located at the upper part of the valley, so workers cannot step on or pass by the connection between deck plates during construction. Construction quality problems such as structural problems or paste leakage or leakage due to excessive deformation of the connection due to the construction material being loaded on the connection or the self-weight of the poured concrete were observed. However, in the present invention, in particular, the rib shape By moving the end bottom plate 13, which is the connection between the deck 10 and the rib-shaped deck 10, to the lower part of the cross-section of the rib-shaped deck 10, the problem of deformation of the connection due to load during construction and water leakage from the connection is solved, improving constructability and safety. This was done to improve writing.

The embossing portions may be formed in oval, long tower, or rectangular shapes at regular intervals, and V-shaped embossing portions such as a seagull may be formed at regular intervals.

In the present invention, the haunch portion 14 compresses a certain section of both ends in the longitudinal direction of the mountain-shaped portion 11 in the direction of the end lower plate 13 to close both ends in the longitudinal direction and protrudes horizontally outward in the longitudinal direction to provide a mounting portion ( 14a) is formed.

In other words, the mounting portion 14a is a part that is mounted on a beam, etc. to ensure stable mounting. In particular, in the present invention, as shown in FIG. 1, the lower part of the mounting portion 14a is located in the central portion in the width direction of each mountain-shaped portion 11. The upper part may protrude so as to be open so that the tie bar insertion groove 15 is formed.
