Embodiment Construction

[0015] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0016] figure 2 is a perspective view schematically showing a sub-composite beam in which a web corrugated steel beam is bonded to a concrete slab, according to a preferred embodiment of the invention, and image 3 is a perspective view which is schematically represented for figure 2 Steel beams in hybrid beams.

[0017] Such as figure 2 and 3 As shown in , a composite beam 1 according to a preferred embodiment of the present invention includes a steel beam 10 and concrete slabs 30 and 40 integrally combining the steel beam 10 at upper and lower sides of the steel beam 10 . Steel beam 10 is made of corrugated steel plate 20 with uniform vertical corrugated pleats, rather than flat steel plate.

[0018] Such as image 3 As shown in , the steel plate forming the web of the steel girder 10 in the present invention is made of corrug...

Abstract

The invention discloses a composite beam wherein the concrete slab is combined with upside and underside of the steel beam with corrugate steel web so as to increase rigidity of the cross section. A prestress concrete composite beam with corrugate steel web contains steel beam, upper and lower concrete slab combined with the upside and underside of the steel beam. The steel web is made of corrugate steel plate with the same corrugate pleat as each other in vertical direction of the beam, thereby increasing resistance to bending. The pylome is formed in upside and underside of the steel beam. Many binding reinforcements insert into the pylome in horizontal direction and embed into the upper and lower concrete slab. Then the steel beam is combined with the upper and lower concrete slab.

Description

technical field [0001] The present invention relates to a prestressed hybrid beam with a concrete slab and a corrugated steel web beam, and more particularly to a composite beam in which the concrete slab is bonded to the upper and lower ends of the steel beam whose web is corrugated thereby Increase the rigidity of its cross-section. Background technique [0002] Beam-Concrete Hybrid Beams, as a type of hybrid beam, are often used in bridge construction in which a steel beam is combined with a concrete slab. figure 1 is a cross-sectional view showing a schematic bridge using conventional steel girder-concrete slab hybrid girders. Such as figure 1 As shown, the conventional steel beam-concrete hybrid beam is constructed such that the lower flange 101 of the I-shaped steel beam 100 is embedded in the concrete slab 110 thereby combining the steel beam 100 with the concrete slab 110 . [0003] Although the concrete slab 110 can be made from concrete at the construction site,...
