Abstract

This invention relates to a reinforcing structure for the joint of a deck plate, and more specifically, to a reinforcing structure for the joint of a deck plate that can prevent the collapse of the deck plate during the construction process of a reinforced concrete structure by providing deck beam supports upright at each end of the deck beam yoke member so as to support the lower panel of a deck slab positioned to be close to the joint.

Description

Joint Part Reinforcement Structure of the Deck Plate This invention relates to a reinforcing structure for the joint of a deck plate, and more specifically, to a reinforcing structure for the joint of a deck plate that can prevent the collapse of the deck plate during the construction process of a reinforced concrete structure by providing deck beam supports upright at each end of the deck beam yoke member so as to support the lower panel of a deck slab positioned to be close to the joint. Generally, reinforced concrete structures are composite structures that utilize both concrete, a compression material, and reinforcing bars, a tension material. They are constructed by preparing formwork using materials such as plywood or lumber, arranging reinforcing bars within the formwork, and repeating the process of pouring and curing concrete, followed by the removal of the formwork. Formwork is a temporary structure provided to shape and dimension concrete while it is still fluid until it is cured, and formwork construction is essential for reinforced concrete structures. In the prior art, an assembled beam deck plate of Registered Patent Publication No. 10-2236580 (March 31, 2021) was proposed to be applicable to the construction of beams of various specifications, but there was a problem in that concrete poured through the gaps leaked during the process of assembling multiple side plate units to correspond to the height of the beam. In addition, when concrete is poured and vibration-compacted on the deck slab and deck beam of a reinforced concrete structure, there was a cause for the side panels of the deck beam at the joint, which is the inner connection part of the deck slab and deck beam, to bulge outwards on both sides, and various troubles occurred, such as the deck slab at the joint also being crushed downwards, leading to the collapse of the structure.
