Membrane jacking rod for supporting truss membrane
The invention discloses a membrane jacking rod for supporting a truss membrane, which effectively solves the tensioning problem of the truss membrane, is simple in tensioning process and remarkable in tensioning effect, and greatly prolongs the service life of the truss membrane while ensuring the safe use of the truss membrane. In order to solve the technical problems, lifting devices are fixedly arranged on tie bars at the top of a truss, ejector rods are arranged on the lifting devices, at least one or more lifting devices are arranged on each ejector rod, a membrane material at the top of the truss is located on the upper sides of the ejector rods, and after the membrane material is laid in place, the lifting devices drive the ejector rods to rise to support and tighten the membrane material. The lower end of a lead screw of the lifting device penetrates through the tie bar, a bottom plate is fixedly arranged at the end of the lower end penetrating through the tie bar and used for preventing the lower end of the lead screw from sliding out of the upper portion of the tie bar, the upper end of the lead screw is fixedly arranged on the ejector rod, the lead screw is sleeved with a nut in a matched mode, and the nut is located on the portion, between the tie bar and the ejector rod, of the lead screw. The nut is rotated to drive the lead screw to move upwards to lift the ejector rod.
本发明公开一种用于支撑桁架膜的顶膜杆，有效解决了桁架膜的张紧问题，张紧过程简单，张紧效果显著，在确保桁架膜安全使用的同时，大大延长了桁架膜的使用寿命；为了解决上述技术问题，升降装置固定设置在桁架顶部的系杆上，顶杆设置在升降装置上，每个顶杆上至少设置有一个或一个以上的升降装置，桁架顶部的膜材位于顶杆上侧，待膜材铺设到位后升降装置驱动顶杆升高，将膜材撑起绷紧，升降装置的丝杠的下端贯穿系杆设置，且在贯穿系杆的下端端部固定设置有底板，底板用于防止丝杠的下端从系杆上方滑出，丝杠的上端固定设置在顶杆上，螺母匹配的套装在丝杠上，且螺母位于系杆和顶杆之间的丝杠上，通过转动螺母驱动丝杠向上运动将顶杆升起。
