Description

Ramp construction structure using PC wall {RAMP STRUCTURE USING PRECAST CONCRETE WALL}

The present invention relates to a ramp construction structure using a PC wall, and more particularly, in a ramp structure of a parking lot or logistics structure, a vertical wall having a ramp corbel is formed along an inclined boundary, and a load of an inclined ramp is received from the vertical wall to form a foundation floor. It relates to a ramp structure that transmits a load to.

Building structures are generally main structural parts such as columns, beams, slabs, and handrails. It is composed of auxiliary structures such as water walls.

The construction methods for constructing building structures include the RC (Reinforced Concrete) structural method in which concrete is poured by arranging molds and reinforcing bars directly on site, and the structure is properly divided, manufactured in a factory, transported, and assembled to pour joints and toppings. It is divided into PC (Precast Concrete) structural construction method.

In the case of a parking lot or logistics structure where vehicles directly enter the building, the connecting passage between floors is made of an inclined ramp. Such an inclined ramp structure should form a structure safely by appropriately binding and transmitting its own weight and the load of a vehicle.

In the inclined ramp structure, the load of the vehicle is received at the bottom of the inclined ramp and transmitted to the boundary structure, and is transmitted vertically from the boundary structure to the foundation floor.

There are two structures that transfer the load from the bottom of the inclined ramp to the foundation floor.

First, inclined beams are placed on the boundary in the same way as the inclined floor, and these inclined beams are connected to vertical columns arranged for each grid. That is, the load of the inclined beam is transmitted to the vertical column and finally to the floor.

The second is a structure in which a vertical wall with a ramp corbel is formed along an inclined boundary in a ramp structure, and the vertical wall receives the load from the inclined ramp floor and transmits the load to the foundation floor.
