预应力混凝土简支梁加固结构
摘要：
本实用新型公开了一种预应力混凝土简支梁加固结构，所述预应力混凝土简支梁加固结构包括设置在所述预应力混凝土简支梁(2)的左侧和/或右侧的辅助钢梁(1)、以及设置在所述预应力混凝土简支梁(2)的跨中位置的横梁(3)，并且所述横梁(3)、所述预应力混凝土简支梁(2)和所述辅助钢梁(1)通过预应力束预应力连接，所述辅助钢梁(1)的两端通过支座支撑，使所述辅助钢梁(1)的自重由支座承担，不增加预应力混凝土简支梁(2)承受的载荷。本实用新型预应力混凝土简支梁加固结构能够提高既有桥梁承载能力和桥梁刚度以满足重载运输要求。
摘要（英）：

The utility model discloses a prestressed concrete simple beam reinforced structure, prestressed concrete simple beam reinforced structure is including setting up the left side of prestressed concrete simple beam (2) and/or supplementary girder steel (1) on right side and setting are in crossbeam (3) of the span centre position of prestressed concrete simple beam (2), and crossbeam (3) prestressed concrete simple beam (2) and supplementary girder steel (1) is connected through pre -stressed reinforcement prestressing force, the both ends of supplementary girder steel (1) are passed through the support and are supported the messenger the dead weight of supplementary girder steel (1) is undertaken by the support, does not increase the load of prestressed concrete simple beam (2) bearing. The utility model discloses prestressed concrete simple beam reinforced structure can improve existing bridge bearing capacity and the requirement is transported in order to satisfy the heavy load to bridge rigidity.
