Deck plate with raised bottom materal}

The present invention relates to a deck plate provided with step reinforcement, and in particular, the bottom of the truss girder is coupled to a plurality of connectors provided as an upper portion of the formwork, the deck plate of the side and the deck plate of the other side is coupled Is to be coupled by step reinforcement.

In general, the concrete structure is a composite structure that is used together with the concrete of the compression material and the reinforcement of the tension material can be obtained by repeating the process of dismantling the curing and formwork by laying the concrete and then reinforcing the reinforcement.

Concrete structure is a method for placing concrete. First, formwork is installed with plywood, lumber, etc., and reinforcement is added to formwork, and then the air becomes longer as the process of casting, curing, and dismantling formwork takes place. There was this.

In order to solve this problem, a truss girder integrated deck that can support the weight of the concrete itself generated during the process of curing the concrete and concrete that is placed between the beams, which are structures for constructing concrete structures, is installed. Plates have been proposed.

The truss girder integrated deck plate is usually provided with a truss girder at the top of the formwork having a predetermined width and the connector is provided at the bottom of the truss girder is coupled so that the form board is detachable, the truss girder is the upper reinforcement, the lower Consists of a reinforcing bar and a lattice material, and the support is coupled to both ends.

However, when the truss girder integrated deck plate is used, the deck plate is installed between the beams and beams. At this time, the height of the formwork on one side and the formwork on the other side do not coincide, which causes a step or step. There was this.

In addition, when the formwork is separated after curing, there was another problem that the step or step is generated at the bottom of the bottom of the slab due to the step or step to inhibit the aesthetics.

In addition, the step or step must be removed, and as a separate removal operation for removing the construction cost increases and at the same time there is a problem such as longer air.
