Roof beam hanging and column pulling transforming and reinforcing method
The invention provides a roof hanging beam and column pulling reinforcing and transforming method, belongs to the technical field of buildings, and aims to solve the secondary problems that an existing supporting beam and column pulling technology affects the clear height of a building, peripheral components need to be reinforced and the like. According to the technical key points, the method mainly comprises the following steps that a stand column needing to be erected with the steel arch is heightened, a column cap for supporting the steel arch is obtained, the steel arch machined in a factory is conveyed to a construction site to be placed at the heightened column cap, the steel arch is connected with a roof beam to be reinforced through a Y-shaped suspender, and roof loads are transmitted to the steel arch through the Y-shaped suspender. And meanwhile, the prestressed steel cables are additionally arranged at the two arch feet of the steel arch frame to balance horizontal thrust generated at the arch feet after the steel arch frame is subjected to roof load transmitted by the suspender. The steel arches, the Y-shaped suspenders and the prestressed steel cables form an independent stress system, the stress performance is excellent, the force transmission path is clear, the requirements for deflection, cracks and bearing capacity of the roof beam lacking of support due to column dismantling are met, and a novel reinforcement and transformation method is creatively provided.
本发明提供了一种屋面吊梁拨柱加固改造方法，属建筑技术领域，旨在解决现有托梁拔柱技术影响建筑净高、需加固周边构件等次生问题。本发明技术要点主要包括以下步骤：对需要架设钢拱架的立柱加高，得到支撑钢拱架的柱帽，将工厂加工好的钢拱架运至施工现场放置在加高柱帽处，钢拱架与拟加固屋面梁通过Y形吊杆相连，屋面荷载通过Y形吊杆传递到钢拱架。同时在钢拱架两拱脚处增设的预应力钢索，以平衡钢拱架受吊杆传来屋面荷载后拱脚处产生的水平推力。钢拱架、Y形吊杆以及预应力钢索形成独立受力体系，受力性能优异，传力路径明确，确保因拆除柱而缺少支撑的屋面梁挠度、裂缝、承载力要求，创造性的提供了一种新的加固改造方法。
