Cast-in-place bent cap of reserved door opening cantilever support and construction method
According to the reserved door opening cantilever support cast-in-place cover beam construction, a cover beam support is arranged on the upper portion of a carriageway to support the cover beam and a cover beam formwork, and a steel box foundation is arranged on the lower carriageway to support an outer side steel pipe column; prefabricated steel pipe column foundations are arranged on carriageways to support inner side steel pipe columns, anti-collision warning barrels are arranged on the outer sides of the carriageways, overhanging fixing supports are arranged on the upper portions of bearing platforms and the prefabricated steel pipe column foundations, steel hoops are arranged on pier columns to fix lower cross beams and back pressure supporting cross beams, and inner inclined struts and outer inclined struts are arranged in the middles of capping beam supports. An upper beam is arranged on the capping beam support. The invention belongs to the field of civil engineering, and relates to a construction method for a reserved door opening cantilever support cast-in-place cover beam structure, which effectively reduces the engineering cost, accelerates the construction speed, and can obtain better technical and economic benefits when being applied to actual engineering.
本发明涉及一种预留门洞悬挑支架现浇盖梁及施工方法，针对预留门洞悬挑支架现浇盖梁施工，行车道上部设置盖梁支架对盖梁和盖梁模板进行支撑，下部行车道上设置钢箱基础对外侧钢管柱进行支撑，行车道上设置预制钢管柱基础对内侧钢管柱进行支撑，行车道外侧设置防撞警示桶，承台和预制钢管柱基础上部设置悬挑固定支架，墩柱上设置钢抱箍对下部横梁、反压支撑横梁进行固定，盖梁支架中部设置内部斜撑和外部斜撑，盖梁支架上部设置上部横梁。本发明属于土木工程领域，针对预留门洞悬挑支架现浇盖梁结构的施工方法，有效降低工程成本，加快施工速度，应用于实际工程中可取得较好的技术经济效益。
