Prefabricated Hybrid Composite Flooring {ASSEMBLY TYPE HYBRID COMPOSITE BASEPLATE}

The present invention relates to a prefabricated hybrid composite floor plate, and more particularly, when installing a slab forming the floor or roof of a structure on the upper side of an upright post installed upright on the ground, it can be easily installed on the upright post by a simple assembly process. The concrete slab effectively supports the concrete slab by a tensile tendon installed inside the timber supporter for supporting the concrete slab, and provides a more robust concrete slab by increasing the response to vertical load, and the concrete slab and the timber It relates to a prefabricated hybrid composite flooring that can provide a composite flooring with improved bonding strength of a supporter.

In general, as a PC method for constructing large space buildings that require long spans such as large stores or factories, Precast Reinforced Concrete Layer Construction using Double Tee Slab, Hollow Core Slab, etc. (Precast Reinforced Concrete Layer Construction) Method) and the PC method applied to buildings of medium scale or less with a lot of load, such as an underground parking lot, includes the PRC complex method using a half PC slab.

This PRC composite method is a method of converting a building with a reinforced concrete structure into PC (Precast Concrete), and transports, lifts, and assembles PC members such as PC columns, PC beams, and half slabs manufactured in the factory to the site. It is a construction method that integrates the structure by pouring concrete over the joint between the joint and the upper part of the half slab on site.

As structural members, PC simple beams and PC girders increase, the overall PC volume increases, which lowers competitiveness compared to other construction methods. , in the case of long spans (over 6m), additional support beams need to be installed for structural mechanics and safety issues, so there is a problem of avoiding construction due to additional unit price increase and reduced floor height.

On the other hand, recently, the double tee slab method has been implemented. That is, it is also called the DTS method, and the double tee slab is formed by installing a deep reinforcing rib on the bottom plate, inserting a strand under the reinforcing rib to apply a tensile force, and then forming an integral member. For this reason, the central part of the body of the double tee slab is formed so that it is raised slightly, and it is mainly applied to above-ground structures with a long span of about 10m or more.

However, in the above-described double tee slab method, it is difficult to achieve a continuous slab form (both ends fixed information) by being seated in the form of a simple beam when crossing the PC beam. There is a problem of weakening, and in order to improve this, the reinforcement rib is additionally installed or the protruding height is increased, which in turn increases the manufacturing cost such as the use of a large number of PC columns, thereby lowering the economic feasibility and increasing the height of the construction structure. There is a problem.
