Tent and prestressed structure truss thereof

XU TUANJIE / LI HANJIE / LI JIEWEI / CHEN JINHUI

The invention discloses a prestressed structure truss. The prestressed structure truss comprises two rows of supporting structures arranged side by side in a spaced mode, a plurality of first prestress components and a plurality of second prestress components, each row of supporting structure is formed by connecting supporting frames connected end to end, the two adjacent rows of supporting structures are connected through a plurality of supporting beams, the supporting beams are provided with first positioning groove holes in the length direction of the supporting beams, the supporting framesare provided with second positioning groove holes in the length direction of the supporting frames, the second positioning groove holes of all the supporting frames in each row of supporting structure communicate with each other in a butt joint mode to form a prestress channel, the second prestress components penetrate through the prestress channels in a sliding and tensioned mode, the supportingstructures forms an integrated structure through the tensioned second prestress components, and the first prestress components penetrate through the first positioning groove holes of the supporting beams in a sliding and tensioned mode and are connected with the supporting structures. The prestressed structure truss has the advantages of effectively saving material cost and being high in structural rigidity. The invention further discloses a tent.

本发明公开了一种预应力结构桁架，其包括两排呈并排且间隔设置的支撑结构、多根第一预应力构件和第二预应力构件，每一排支撑结构由相互首尾相接的支撑架连接形成，相邻两排支撑结构借由多根支撑梁连接，支撑梁沿其长度方向开设有第一定位槽孔，支撑架沿其长度方向开设有第二定位槽孔，同一支撑结构中的所有支撑架的第二定位槽孔对接连通而形成一预应力通道，第二预应力构件呈滑动的张紧穿过预应力通道，支撑结构借由张紧的第二预应力构件而形成一体式结构，第一预应力构件呈滑动的张紧穿过于支撑梁的第一定位槽孔并与支撑结构连接。本发明的预应力结构桁架具有有效节约物料成本和结构刚性高的优点。本发明还公开了一种篷房。
