Honeycomb Type Composite Beam Stiffened with Prestressed Concrete Panel having Novel Connecting Structure

摘要

The invention is pre-cast concrete panels and the steel beams are connected to more robust behavior to be fully integrated structurally, and, to a precast concrete panel composite beam assembly having a structure in which the assembly is easy. In the present invention, the steel beam 10 and the pre-cast concrete panels 20 as a composite beam of the structure to be assembled integrally, the abdomen cut part (14) (12) has cut the abdominal inner side of the steel beam 10 is It made of a honeycomb girder type formed at a predetermined interval, the lower portion of the part which is not cut away from the abdomen 12 of the steel beam 10 is provided with a bottom flange 31 having a predetermined length and width is integrally attached to and; The precast concrete panel 20 is the inside and the longitudinal reinforcement 24 and the lateral reinforcement 25 is reinforcement, its upper surface accommodating concave bottom flange to accommodate the lower flange 31 part ( 21) it is formed, and; A side wall of the concave bottom flange receiving portion 21 is equipped are reinforced filling the vagina 23, one end of the reinforced vagina 23 is coupled to the end integral with the transverse reinforcement (25); The other end of the reinforced joints 23 are connected to reinforcement 22 is received in the lower flange receiving portion 21 of the, the combined lower flange 31 of the steel beam 10, the precast concrete panels (20) when, the connecting reinforcement 22 is integrally attached to a lower surface of the lower flange (31); The lower flange 31 of the lower flange receiving part 21, the lower flange receiving portion (21) Non-shrink concrete is being the cured casting, the honeycomb girder-shaped steel beam in housed state of the steel beam 10 ( 10) and the pre-cast concrete panels 20 are provided with a honeycomb-shaped girder precast concrete panel composite beam having a structure in which the composite assembled as one body. Here, the the bottom surface of the lower flange 31, and the steel beam 10 is pre-cast height for adjusting concrete panels allowed to equilibrate when it is placed on the lower flange receiving portion 21 to be coupled to the 20 adjustment member ( 33) it is provided with.
