Method for additionally arranging fulcrum column under beam
The invention discloses a method for additionally arranging a fulcrum column under a beam. The method comprises the following steps: pre-planting a steel bar at a position where the fulcrum column is additionally arranged on a reinforced beam; a first supporting assembly, a second supporting assembly and a splicing top-supporting cross beam are arranged below the reinforced beam, the splicing top-supporting cross beam comprises a first beam section, a second beam section and a third beam section, the splicing top-supporting cross beam is transversely placed on the first supporting assembly and the second supporting assembly, and the pre-planted steel bars penetrate through the steel bar pre-penetrating holes in the vertical direction; jacking equipment arranged on the first supporting assembly and the second supporting assembly is used for jacking the spliced jacking and supporting cross beam, and a second beam section of the spliced jacking and supporting cross beam applies pre-stressing force to the reinforced beam; pouring of an added fulcrum column is conducted, and the second beam section is poured into the fulcrum column during pouring; and the first supporting assembly, the second supporting assembly, the first beam section and the third beam section are dismantled. The method can be used for additionally arranging permanent reinforced concrete column fulcrums capable of cooperatively working for an existing structure, and the difficulty of reconstruction and reinforcement engineering is reduced.
本发明公开了一种梁下增设支点柱的方法，包括以下步骤：在被加固梁的增设支点柱的位置预植钢筋；在被加固梁的下方设置第一支撑组件、第二支撑组件和拼接顶支横梁，其中，拼接顶支横梁包括第一梁段、第二梁段和第三梁段，将拼接顶支横梁横向放置于第一支撑组件和第二支撑组件，将预植的钢筋沿竖向穿过钢筋预穿孔；通过设置于第一支撑组件、第二支撑组件的顶升设备顶升拼接顶支横梁，拼接顶支横梁的第二梁段对被加固梁施加预加力；进行增设的支点柱的浇筑，浇筑时将第二梁段浇筑于支点柱中；拆除第一支撑组件、第二支撑组件、第一梁段和第三梁段。本发明能够用于对既有结构增设可协同工作的永久性钢筋混凝土柱支点，降低改造加固工程的难度。
