Large-span prestress arch crown structure construction method and device
The invention relates to the technical field of building construction, and provides a large-span prestress vault structure construction method and device.The method comprises the following steps that a to-be-constructed vault structure is divided into a plurality of sliding assembling units in the sliding direction; sliding rails are installed at the two ends of the vault structure; a sliding trolley is installed on the starting section of the sliding rail; the sliding seat, connected with the beam base and the upper section steel column, of one sliding assembly unit is installed on the sliding trolley; a supporting jig frame is erected, an arched beam of the sliding assembling unit is assembled, and the arched beam is connected with beam bases at the two ends of the arched beam; a tensioning steel strand is installed and tensioned; a traction device is used for pulling the sliding trolley to move to the target position of the sliding assembly unit on the sliding rail; the steps are repeated until all the sliding assembling units of the arch crown structure are installed; and the supporting jig frame, the prestress tensioning steel strand and the sliding rail are dismantled. The construction progress is accelerated, social resources are saved, and the engineering cost is saved.
本申请涉及建筑施工技术领域，提供一种大跨度预应力拱顶结构施工方法及装置，方法包括以下步骤：将拟施工的拱顶结构沿滑移方向划分为若干个滑移拼装单元；安装滑移轨道于拱顶结构的两端；将滑移小车安装在所述滑移轨道的起始段；将一个滑移拼装单元的连接有梁底座和上节钢柱的滑动座安装在滑移小车上；搭设支撑胎架，拼装该滑移拼装单元的拱梁，并将拱梁与其两端的梁底座连接；安装张拉钢绞线并张拉；利用牵引装置牵引滑移小车在滑移轨道上移动至该滑移拼装单元的目标位置；重复上述步骤，直至拱顶结构的全部滑移拼装单元完成安装；拆除支撑胎架、预应力张拉钢绞线和滑移轨道。本发明加快了施工进度、节约了社会资源、节省了工程成本。
