Large-span wood arch structure reinforced by prestress
The large-span wood arch structure comprises a main body structure, a wood arch and an inhaul cable, the lower end of the wood arch is fixedly connected to the upper end of the main body structure, the wood arch is divided into a plurality of wood arch sections, the wood arch sections are fixedly connected at the splicing structure position to form the continuous wood arch, and the inhaul cable is arranged between the wood arch sections. The inhaul cables are connected with the wood arch on the inner lower side of the wood arch through the lug plate structures, the number of the lug plate structures is multiple, the inhaul cables are connected on the inner lower side of the whole wood arch through the lug plate structures in a spanning distribution mode, and the number of the inhaul cables is two. The lug plate structures of one set of inhaul cables and the lug plate structures of the other set of inhaul cables are staggered by one point in the transverse direction of the large-span wood arch roof, and the two sets of inhaul cables are distributed in a crossed linear array mode in the longitudinal direction of the large-span wood arch roof. The wood arch roof structure has the beneficial effects that the problem that the utilization efficiency of an existing wood arch roof structure is reduced and even the structure safety is affected under adverse conditions is solved, and meanwhile the clear height and the visual impression effect of the wood arch roof are prevented from being affected.
本发明公开了一种采用预应力增强的大跨度木拱结构，包括：主体结构、木拱和拉索，木拱的下端固定连接在主体结构的上端，木拱分为多段木拱段，木拱段与木拱段之间在拼接结构处固定连接并组成连续的木拱，拉索通过耳板结构在木拱的内下侧与木拱连接，耳板结构的个数为多个，拉索通过耳板结构在整个木拱的内下侧跨越式分布连接，拉索具有两组，其中一组拉索的耳板结构与另一组的耳板结构在大跨度木拱屋盖的横向方向上相互错开一个点位，两组拉索在大跨度木拱屋盖的纵向方向上相互交差的线性阵列分布，本发明的有益效果：解决了现有的木拱屋盖结构在不利情况下利用效率降低甚至影响结构安全的问题，同时避免影响木拱屋盖净高和视觉观感效果。
