Closing device for large-span steel truss arch closure section
The invention discloses a closure device for a closure section of a large-span steel truss arch, which comprises stress seats correspondingly arranged on a closure main body, a fastener and a wedge block, the fastener and the wedge block are arranged between the two stress seats, and a wedge opening matched with the wedge block is formed between the two stress seats. By the adoption of the method, welding is not needed in the steel truss arch folding process, and therefore the whole construction process has the advantages of being higher in efficiency and shorter in hoisting equipment and site occupation time. The folding device can also be used for quickly folding structures such as arch trusses, pipe frames and box girders of various material types such as concrete structures and steel structures.
本发明公开了一种用于大跨度钢桁拱合拢段的合拢装置，包括对应设在在合拢主体上的受力座、设在所述两受力座之间的紧固件和楔块，所述两受力座之间形成与所述楔块配合的楔口。采用本发明可以在钢桁拱合拢过程中无需进行焊接，因而整个施工过程具有效率更高、占用吊装设备和场地时间更短的优点。本发明合拢还可以用来实现混凝土结构、钢结构等各种材料类型的拱形桁架、管架、箱梁等结构物的快速合拢。
