Reinforcing method of brick-concrete structure low-strength concrete flower basket beam
The invention belongs to the technical field of building structure reinforcement, and discloses a reinforcement method of a brick-concrete structure low-strength concrete flower basket beam to solve the problems that in the prior art, the flower basket beam reinforcement cost is high, the dead weight of a reinforcement beam is greatly increased, the lower use space is greatly influenced, and new and old concrete is prone to hollowing. The method comprises the steps of designing the bearing capacity, determining stress angle steel, chiseling away the lower edge of an original flower basket beam, pouring a static dismantling hole, welding a steel batten plate, installing a support, blocking, pressing and smearing polymer mortar and the like, the bearing capacity of the flower basket beam can be reliably improved, original usability can be well kept, meanwhile, the weight of the structure is slightly increased, and the service life of the structure is prolonged. The characteristics of steel and concrete materials are fully utilized, meanwhile, the problem of concentrated stress at the beam support is solved, section steel combined steel-clad reinforcement is adopted, the beam bearing capacity is effectively improved, the reinforcement dead weight is reduced, and the influence of beam reinforcement on the lower use space is reduced.
本发明属于建筑结构加固技术领域，公开了涉及砖混结构低强度混凝土花篮梁的加固方法，以解决现有技术花篮梁加固成本高、加固梁自重增加大、下部使用空间影响较大、新旧混凝土容易空鼓等问题，该方法包括设计承载力确定受力角钢、对原花篮梁的下边部进行凿除、浇筑静力拆除孔、焊接钢缀板、安装支座、封堵、压抹聚合物砂浆等步骤，本发明能够可靠的提高花篮梁承载力，能够较好的保持原有的使用性，同时对结构自身重量增加较少，充分利用钢材与混凝土材料特点，同时解决梁支座处集中受力问题，本发明采用型钢组合包钢加固，有效提高梁承载力、降低加固自重、减少梁加固对下部使用空间影响。
