Description

Ramp construction structure of logistics structure applying PC method {RAMP CONSTRUCTION STRUCTURE OF WAREHOUSE USING PRECAST CONCRETE CONSTRUCTION METHOD}

The present invention relates to a lamp construction structure of a logistic structure to which the PC method is applied, and more particularly, to the lamp construction structure of a safe distribution structure for each construction stage of PC columns, beams, slabs, handrails and water wall members according to the application of the PC method. .

Architectural structures are usually major structural parts such as columns, beams, slabs, and railings. It is composed of ancillary structures such as water walls.

The construction method for building structures consists of the RC (Reinforced Concrete) structure method, in which the concrete is poured by placing the formwork and rebar directly on site, and the structure is properly divided and manufactured at the factory, transported and assembled, and the joint and topping are poured. It is divided into PC (Precast Concrete) structure method to be constructed.

Currently, large-scale logistical structures are constructed in such a way that large trucks can directly go up to each floor and berth for loading and unloading.

The recent trend is to build large-span structures such as logistics structures by applying the PC method, which has the advantage of low vibration, excellent quality assurance, and fast construction period.

However, compared to the main building, the ramp is formed by a ramp, and in particular, due to the nature of the floor level in which the curved section is twisted up, the railing and water wall are hung from the external edge beam. It is true that it is very difficult to apply

Failure to properly design safety for each stage of construction directly leads to a major accident, and its importance is even more urgent, even in the recent case of major accidents.
