KR19980044226A - Connecting device of reinforced concrete column and steel beam joint (1) - Google Patents

Abstract

The present invention relates to a joint connecting device in which a column and a beam meet in a composite structure consisting of a reinforced concrete column and a steel beam. It has an upper band plate and a lower band plate and has a cross-shaped intermediate plate inside the outer periphery of the upper and lower band plates, respectively. The upper band plate and the lower band plate are joined to each other by vertically welding four side plates.

Stresses generated at the joints of columns and beams have bending moments and shear forces. The bending moment acts as tensile and compressive stresses on the upper and lower flanges of the steel beams, which are transmitted to the upper band plate and the lower band plate, and transmitted to the column by the outer plate and the cross-shaped intermediate plate attached to the band plate to stabilize the joint. Will be

The present invention is to provide an apparatus for ensuring the connection of a joint when using reinforced concrete as a pillar material and steel material as a long span member. The device can be manufactured in the factory, the structural performance of the product is assured, and the column concrete can be easily placed, thus providing a connection construction device with excellent workability.

Field of invention

The present invention relates to a joining device for connecting reinforced concrete columns and steel beams in a structure. Reinforced concrete and steel member have different functions, each with its own function. When the reinforced concrete member and the steel member are mixed, structural performances are different from each other. Therefore, it is necessary to specially design the joint to properly transmit the stress of the member. The present invention relates to an apparatus for assuring the stress transfer of this joint.

Background of the Invention

The composite structure that combines reinforced concrete columns and steel beams has reinforced concrete columns with excellent performance in compressive force and steel beams with excellent performance in tensile force. Although the joining method is clear in a single structure, ensuring continuity is an important concern at joints where heterogeneous materials meet. If the beams penetrate the column integrally (beam through type) at the joint, it is advantageous to the strength of the beam, but it is more likely to cause problems in the continuity of the column.If the column is constructed integrally and the beam wraps around the column (pillar through type), it is advantageous for the column. The strength of the beam is disadvantageous. Therefore, in the structural type of reinforced concrete column-steel beams, it is important to develop a joint connection device that can effectively support the stress transmitted from the beam and the column.

In the joint, the column section is missing, it is difficult to reinforce the column reinforcement, and it is difficult to fill the concrete, so it is urgently required to develop a joint apparatus that can solve this problem and effectively transmit stress. The present invention has been made to solve this problem.
