Prestressed steel beam overlapping reinforcing structure of existing concrete beam
The invention discloses a prestress steel beam overlapping reinforcing structure of an existing concrete beam, and aims to provide the prestress steel beam overlapping reinforcing structure capable ofreinforcing the existing concrete beam which cannot be subjected to concrete pouring and tamping reinforcement at the bottom or on the surface of the beam under the condition that the section of theexisting concrete beam does not need to be enlarged and the use space of an original building is not reduced, so as to improve the bearing capacity of the existing concrete beam. The prestress steel beam overlapping reinforcing structure comprises a reinforced beam, a reinforcing steel beam, a connecting structure body and prestressed tendons, wherein the connecting structure body comprises anchorbolts implanted into the reinforced beam, the upper ends of the anchor bolts are located above the reinforcing beam, the reinforcing steel beam is located above the reinforced beam, and the reinforcing steel beam and the reinforced beam are connected into a whole through the anchor bolts. The prestressed tendons extend in the length direction of the reinforced steel beam and apply pre-pressing force to the lower portion of the reinforced steel beam so as to improve the bearing capacity of the reinforced steel beam.
本发明公开了一种既有混凝土梁的预应力钢梁叠合加固结构，旨在提供一种可以在不需加大既有混凝土梁截面，不降低原有建筑使用空间的情况下，对无法在梁底或梁面做混凝土浇捣加固的既有混凝土梁进行加固，以提高既有混凝土梁的承载力的既有混凝土梁的预应力钢梁叠合加固结构。它包括被加固梁、加固钢梁、连接结构及预应力筋，所述连接结构包括植入被加固梁内的锚栓，所述锚栓的上端位于被加固梁的上方，所述加固钢梁位于被加固梁的上方，所述加固钢梁通过锚栓与被加固梁连接为一体，所述预应力筋沿加固钢梁的长度方向延伸，且预应力筋对加固钢梁的下部施加预压紧力，以提高加固钢梁的承载力。
