Cast-in-place continuous box girder construction system and construction technology
The invention relates to the technical field of bridge construction, in particular to a cast-in-place continuous box girder construction system and a construction technology. The cast-in-place continuous box girder construction system comprises a formwork device, the formwork device comprises an outer formwork, an inner formwork, a top formwork and an end formwork, the outer formwork, the top formwork and the end formwork define a closed structure, and the inner formwork is arranged in the closed structure; the two axial ends of the inner mold abut against the end molds, an isolation supporting mechanism is arranged between the outer mold and the inner mold and comprises a supporting steel bar, abutting ends and clamping ends, the abutting ends are fixed to the two axial ends of the supporting steel bar, and the clamping ends are arranged at the ends, away from the supporting steel bar, of the abutting ends. The ends, away from the steel bars, of the abutting ends abut against the sides, close to each other, of the inner mold and the outer mold, and the clamping ends are clamped and fixed to the inner mold or the outer mold. The cast-in-place continuous box girder construction system has the following effects that the inner mold is fixed through the isolation supporting mechanism and is kept stable in the outer mold and not prone to shaking, and therefore deviation is not prone to being generated after a continuous box girder is formed.
本申请涉及桥梁施工技术领域，尤其是涉及一种现浇连续箱梁施工系统及施工工艺，现浇连续箱梁施工系统包括模板装置，模板装置包括外模、内模、顶模和端模，外模、顶模和端模围合形成封闭结构，内模设在封闭结构内，内模轴向的两端与端模相抵接，外模和内模之间设有隔离支撑机构，隔离支撑机构包括支撑钢筋、抵接端头和卡接端头，抵接端头固定在支撑钢筋轴向的两端，卡接端头设在抵接端头远离支撑钢筋的一端，抵接端头远离钢筋的一端与内模和外模相互靠近的一侧相抵接，卡接端头卡接固定在内模或者外模上。本申请具有以下效果：内模由于隔离支撑机构的固定，在外模内保持稳固且不易产生晃动，因此连续箱梁成型后不易产生偏差。
