Abstract
The present invention relates to a composite beam in which a fabricated truss is embedded in the concrete, and more particularly, it relates to a composite beam in which the fabricated truss acts as a truss beam which endures the concrete weight and the construction load in the liquid phase before the curing of the concrete and acts as a main structural member together with the concrete after the curing of the concrete.
Claims10
A flush type fabricated truss composite beam attached with a sheathing board comprising a fabricated truss, a sheathing board and a concrete,
- wherein the fabricated truss comprises:
- a lower chord consisted in a plate shape of a predetermined thickness, wherein screw rods formed with a screw thread on both ends or along the entire length are combined to the lower chord with a predetermined spacing along a length direction so as to protrude in the width direction;
- a pair of folding type web members composed in a zigzag form by connecting ends of plural flat steels, wherein the screw rod combined to the lower chord penetrates a penetrating hole formed at a connecting portion of the flat steel and a D cone is screwed so that the lower ends of the folding type web member are combined to both ends of the lower chord in the width direction;
- and
- a pair of upper chords comprising a vertical plate at which combination holes are pierced along the length direction with a predetermined spacing and a horizontal plate composed at the upper end of the vertical plate, wherein the screw rod penetrates the combination hole of the vertical plate and the upper penetration hole of the folding type web member, and a D cone is screwed at the outside so that the pair of upper chords are combined to the pair of folding type web members,
- wherein the sheathing board is formed by a pair of side wall sheathing boards and a U shape lower sheathing board so that the lower ends of a pair of side wall sheathing boards are overlapped at both sides of the U shape lower sheathing board so as to have a U shape section in which the upper surface is opened so as to receive the fabricated truss in its section, and bolt holes are pierced at positions corresponding to the D cone combined to the upper chord and the lower chord of the fabricated truss and a bolt is combined to the D cone through the bolt hole at the outside so that the sheathing board is fixed to the fabricated truss,
- wherein the concrete is integrated with the fabricated truss by being poured into the section of the sheathing board, and
- wherein the sheathing board is removed by unscrewing the bolt after curing of the concrete.
