Single-layer grid string structure and construction method
The invention discloses a single-layer grid string structure and a construction method. The single-layer grid string structure comprises a grid part, a bifurcate column, a string cable and a strut. The grid part comprises grid beams which intersect to form a single-layer grid. The string cable is tightened below the grid part. The strut is connected with the grid part and the string cable. The construction method comprises the steps that platy grid sections, the bifurcate column and a plurality of support tire frames are arranged, the grid sections in each single span are lifted, the adjacentgrid sections are connected to form single-span grid units, the grid units slide backwards by a span, the adjacent grid units are connected to form the grid part, the string cable is inserted into thelower portion of the grid part, and stretching is conducted. Through an accumulative sliding mode, the grid sections are lifted and connected continuously, and the construction process is simple andfast. The single-layer grid part is formed after the multiple grid sections are lifted and spliced, the grid part is simple and light in structure, and the defects that a traditional single-layer gridstring structure is provided with many rod parts, assembly is complex, and the construction quantity is high are overcome.
本发明公开了一种单层网格张弦结构及施工方法，单层网格张弦结构包括网格部、分叉柱、弦索及撑杆，网格部包括网格梁相互交叉形成单层的网格，弦索绷紧于网格部下方，撑杆与网格部及弦索连接；施工方法包括设置片状网格节段、分叉柱及若干支撑胎架，吊装单个跨度内的网格节段，连接相邻的网格节段形成单跨的网格单元，网格单元向后滑移一个跨度，连接相邻的网格单元形成网格部，在网格部下方插入弦索，并进行张拉。通过累积滑移的方式，使网格节段不断进行吊装及连接，施工过程简单、快捷；多个网格节段吊装拼接完成后形成单层的网格部，网格部的结构简单、轻盈，克服了传统单层网格张弦结构杆件多、组装复杂、施工量大的缺陷。
