Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a precast deck plate and a concrete slab construction method using the precast deck plate,

The present invention relates to a precast deck plate and a concrete slab construction method using the precast deck plate. More specifically, it is possible to manufacture a bridge or a construction slab in a factory and to easily transport the slab to a construction site, The present invention relates to a precast deck plate and a method of constructing a concrete slab using the precast deck plate.

The most common method of constructing a reinforced concrete slab in a general reinforced concrete structure is to construct a concrete form to form the outer surface of the concrete and a tread to support the concrete. The reinforced concrete is laid on the form, After the concrete is cured after a curing process for a certain period of time, the process is performed to remove the form and the tall building.

However, this method requires a lot of manpower and work depending on the hypothesis and dismantling of the formwork and the tall building, and it is necessary to perform a separate reinforcement work, and when the concrete is cured and the form is taken out, There is a problem in that a considerable amount of air is required to be consumed and economical efficiency is deteriorated due to the generation of waste materials due to damage to the form when the form is dismantled.

Therefore, in recent years, a deck panel made of a deck plate serving as a form and a truss girder installed to maintain the strength of the slab on the deck plate is used to form a slab of reinforced concrete Deck slab construction method is mainly used.

A representative example of this new type of slab construction method is a method using a DeckPlate.

In other words, the deck plate is used as a permanent form for the slab concrete pouring, and then the deck plate is manufactured. Then, at the construction site, the deck plate is used as a permanent form by using a crane or a work truck, A deck plate using a steel plate is known as a main advantage in that it is combined with a slab concrete and a construction simplicity in which a separate form dismantling is not required, which is disclosed in Laid-Open Patent Application No. 10-2009-0004053.

However, in the investigation of slab cracks, which is one of the most important inspection items required for the smooth maintenance of bridges, it is almost impossible to confirm that the deck plate is steel, and rust is generated on the surface of the steel deck plate, And when a steel material having a significantly low rigidity is used as a deck plate, excessive sagging occurs during the construction of the slab.

In consideration of this, a method of using a precast concrete panel as a deck plate has been introduced. Such a deck plate can be made to conform to the structural behavior of the slab by the complete synthesis with the slab concrete, And 635137 because of the fact that the stiffness of the city dies is large and the safety is secured easily during construction.
