Large-span cantilever tensile counterweight roof structure and construction method thereof
The invention relates to a large-span cantilever tensile counterweight roof structure and a construction method thereof. The method comprises the steps that counterweight beams and counterweight columns are installed on a secondary roof layer, and the counterweight columns achieve horizontal limiting connection through a temporary connection structure; a temporary supporting structure is arranged on a lower layer structure to support the cantilever ends of the counterweight beams; outer ring beams are fixedly connected to the cantilever ends of the counterweight beams; inhaul cables are vertically connected between the lower layer structure and the outer ring beams, the inhaul cables are tensioned when connected, and the inhaul cables are fixedly connected with the corresponding outer ring beams after being tensioned; the counterweight columns are fixedly connected with a secondary roof layer, and the temporary connection structure and the temporary supporting structure are dismantled, so that construction of the counterweight roof structure is completed. A tensile force transmission structure is formed on the periphery of the counterweight roof structure through the inhaul cables, and the safety degree and stability of a cantilever part are improved. In the installation process, stress accumulation of integral deformation of the roof caused by tensioning of the inhaul cables can be avoided through horizontal limiting connection of the counterweight columns.
本发明涉及一种大跨度悬挑抗拉型配重屋面结构及其施工方法，该方法包括：于次屋面层之上安装配重梁和配重柱，将配重柱通过临时连接结构实现水平限位连接；于下层结构上设置临时支撑结构以支撑配重梁的悬挑端；将外圈梁固定连接在配重梁的悬挑端；将拉索竖向连接在下层结构和外圈梁之间，在连接拉索时对拉索进行张拉，经张拉后再将拉索与对应的外圈梁固定连接；将配重柱与次屋面层固定连接，并将临时连接结构和临时支撑结构拆除，从而完成了配重屋面结构的施工。本发明利用拉索在配重屋面结构的外周形成抗拉传力结构，提高了悬挑部位的安全度及稳定性。在安装过程中，配重柱的水平限位连接能够避免拉索在张拉时造成屋面整体变形的应力积累。
