Construction method of large-span irregular trusses
The invention discloses a construction method of large-span irregular trusses. The method includes the steps that the large-span irregular trusses with different bottom elevations are divided into regular partial trusses with same bottom elevation and residual irregular partial trusses in advance; then the regular partial trusses are assembled on a ground home position; the regular partial trussesare lifted to a specific elevation (the elevation of satisfying the mounting requirement of bottom irregular partial trusses) and hovered at the low altitude after assembly, and the regular partial trusses are subjected to temporary fixing constraint measures; the regular partial trusses act as a support system to assemble the residual irregular partial trusses at the low altitude; and the large-span irregular trusses are lifted to a design elevator wholly and mounted and fixed after the irregular partial trusses are assembled completely. According to the method, on the basis of lowering construction safety hazards, the construction efficiency can be greatly improved, a great number of temporary support facility building costs can be saved, good economic benefits can be achieved, and themethod has the advantages of safety, economy, and efficiency and the like.
本发明公开了一种大跨度不规则桁架的施工方法，包括步骤：预先将底面标高不同的大跨度不规则桁架划分为底面标高相同的规则部分桁架和剩余的不规则部分桁架；然后，先在地面原位拼装规则部分桁架；拼装完后将规则部分桁架提升至特定标高(满足底面不规则部分桁架安装需求的标高)后低空悬停，并对规则部分桁架施加临时固定约束措施；再利用规则部分桁架作为支撑体系低悬空拼装剩余的不规则部分桁架；待不规则桁架完全拼装完成后，将大跨度不规则桁架整体提升至设计标高，并安装固定。本发明能在降低施工安全隐患的基础上，大幅提高施工效率，节省大量临时支撑设施搭设费用，具有良好的经济效益，具有安全、经济、高效等优点。
