Abstract
The invention relates to the concrete and pre-stress concrete beam with transition area, which provides a concrete structure of civil engineering. The invention comprises first concrete or pre-stress concrete beam (1), second concrete or pre-stress concrete beam (2) and a transition area (3). Wherein, the first and second concrete or pre-stress concrete beam (1, 2) are parallel opposite arranged; the transition area (3) is integrated with the end (1-1) of first concrete or pre-stress concrete beam (1) and the end (2-1) of second concrete or pre-stress concrete beam (2). The invention has the advantages that: it uses transition area to connect the beams as a whole to support, and since it uses the beams as main beam, it can reduce the height of concrete plane system to reduce cost, improve application function and optimize the system. And the transition area can realize the extension of pre-stress bar of pre-stress concrete beam.
Description
Technical field
