Description

FRAME PANEL SUPPORTING APPARATUS FOR CONCRETE CASTING A BRIDGE STRUCTURE}

The present invention relates to a formwork supporting device for placing a bridge deck for supporting the formwork panel used when placing the bridge deck into concrete until curing of concrete.

In general, bridges are divided into slab bridges, girder bridges, truss bridges, arch bridges, ramen bridges, suspension bridges, and cable-stayed bridges according to their superstructures. Among them, girder bridges are further divided into T-shape, plate shape, steel box type, and the like. Shows a partial bottom perspective view of a typical steel box-type bridge.

In the case of the steel box-type bridge (3), as shown in Figure 1, after installing a bridge device (not shown) on the top of the concrete pier (4), the steel box (5) is placed on the top of the bridge device Next, the lattice structure 6 is formed by the horizontal beam 6a and the vertical beam 6b so as to have a predetermined equal interval on the upper side and the side of the steel box 5 to form the entire bridge structure. After the formwork panel is installed on the lattice-shaped space formed by this, the concrete is poured and cured to finish by pouring the bridge slab 7.

However, in order to install the formwork for placing the bridge slab (7), the scaffolding structure is piled up from the ground to almost the floor height of the bridge slab (7), and then the joists and yokes are laminated to each other and the plywood formwork is placed on the top. When the panel should be installed and when the bridge slab (7) is completed, all the dismantling and repetition of the above-mentioned work in the next section will not only reduce work efficiency, but also increase the construction period and construction cost of the whole bridge. There is a problem that the dismantling work of the formwork panel is very complicated, and safety accidents are frequently caused by falling objects during the dismantling work.

In addition, the left and right edges of the bridge deck slab (7) is also formed to be obliquely sloped at a predetermined slope, the proper form support device for the installation of the formwork for placing the left and right edges of the bridge deck slab (7) has not been developed a lot of difficulties in construction There was a problem.
