Prestress superimposed reinforced concrete beam and construction method thereof
The invention discloses a prestressed superimposed reinforced concrete beam and a construction method thereof, and aims to provide a prestressed superimposed reinforced concrete beam which can reinforce an original concrete beam under the condition that the beam height of the original concrete beam of a building is not changed so as to meet the requirements of bearing capacity and normal use. Therefore, the problem of reinforcement of the beam under the condition that the clear height requirement of a building is high is effectively solved. A prestressed superimposed reinforced concrete beam comprises an original concrete beam, and at least one of the two sides of the original concrete beam in the beam width direction is provided with a prestressed reinforced concrete beam. The pre-stress reinforced concrete beam comprises a steel reinforcement framework which comprises a plurality of shear-resistant steel bars, and one ends of the shear-resistant steel bars are implanted into an original concrete beam; and the prestressed tendons are embedded in the prestressed reinforced concrete beams, and stress is applied through the prestressed tendons, so that upward anti-arch force is generated by the prestressed reinforced concrete beams and the original concrete beams.
本发明公开了一种预应力叠合加固混凝土梁及其施工方法，旨在提供一种能够在不改变建筑物原混凝土梁的梁高的情况下，对原混凝土梁进行加固，以满足承载力与正常使用要求，从而有效解决建筑净高要求较高情况下梁的加固问题的预应力叠合加固混凝土梁及其施工方法。一种预应力叠合加固混凝土梁，包括原混凝土梁，原混凝土梁在梁宽方向上的两侧中至少有一侧设有预应力加固混凝土梁；预应力加固混凝土梁包括：钢筋骨架，其包括若干抗剪钢筋，抗剪钢筋的一端植入原混凝土梁内；预应力筋，其埋设在预应力加固混凝土梁内，并通过预应力筋施加应力，以使预应力加固混凝土梁和原混凝土梁产生向上的反拱力。
