Hinging joint structure of large-span prestressed concrete framed girder

Abstract

The invention provides a hinging joint structure of a large-span prestressed concrete framed girder. The hinging joint structure comprises a framed girder (1) and a framed column (2) which are integrally connected to form a prestressed concrete frame structure. The hinging joint structure is characterized in that an inner side isolating layer (3) and an outer side isolating layer (4) are respectively arranged at the inner side and the outer side of a plane in which the bottom surface of the framed girder (1) is intersected with the top surface of the framed column (2); the framed girder (1) and the framed column (2) are connected through a reinforced concrete core column (5); a reinforced concrete girder pad (6) is arranged at one inner side of the framed girder (1), at the inner side plate isolating layer (3). According to the hinging joint structure, a side column of the large-span prestressed concrete frame of a roof is structured into a single hinging form, thus the bending moment transmitted by the large-span prestressed concrete framed girder can be released, the framed column at the side can be kept in a small-eccentric pressing state, and as a result, the quantity of reinforcement and the section dimension can be reduced, the bearing performance of the frame structure can be improved, and the large-space design requirement of a building is met.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a prestressed concrete frame beam hinge joint structure, which can improve the stress condition of a large-span prestressed concrete frame. Background technique [0002] In construction engineering technology, in order to obtain a larger space for use, the prestressed concrete frame structure is a commonly used structure type, but when the top floor of the building adopts a large-span prestressed concrete frame structure, the axial pressure on the side frame columns is relatively high. It is small, but the bending moment is very large, so it is necessary to configure a lot of stressed steel bars or use a large column section size. However, too many frame columns will lead to dense steel bars, which will affect the quality of concrete pouring and increase the cost. Increasing the cross-sectional size of the frame columns will not only unreasonable stru...

Problems solved by technology

[0003] The purpose of the present invention is to provide a long-span prestressed concrete frame beam-hinge joint structure aiming at the technical defect of the large-span prestressed concrete frame column in the existing construction project that the force and bending moment are too large. The side columns of the frame are set in a single-item hinged structure to release the bending moment transmitted by the long-span prestressed concrete frame beams, so that the side frame columns are in a small eccentric compression state, reduce the amount of reinforcement and section size, and improve the mechanical performance of the frame structure. Meet the design requirements of large building spaces
