Double-layer prestress adjustable truss
The invention relates to the field of building supplies, in particular to a double-layer prestress adjustable truss which comprises two sets of independent truss units, each independent truss unit comprises a first cross rod and a second cross rod which are parallel to each other, and a plurality of split supporting rods are arranged between the two second cross rods of the two sets of independent truss units. A top supporting rod parallel to the first transverse rod is further arranged above the first transverse rod, an end supporting rod is arranged at the end of the top supporting rod and connected to the first transverse rod, a pre-drawing wire rod perpendicular to the top supporting rod is arranged on the top supporting rod in a sliding and penetrating mode, and a first nut is in threaded connection with the rod body, opposite to the top supporting rod and back to the first transverse rod, of the pre-drawing wire rod. A plurality of pre-drawing assemblies are sequentially arranged on the rod body, opposite to the top supporting rod and facing the side of the first transverse rod, of the pre-drawing wire rod, each pre-drawing assembly comprises two pull rods, and each pull rod is connected to one split supporting rod. The method has the advantage that the service life of the truss is prolonged.
本发明涉及建筑用品领域，尤其是涉及一种双层预应力可调式桁架，其包括两组独立桁架单元，独立桁架单元包括相互平行的第一横杆和第二横杆，两组独立桁架单元的两个第二横杆之间均设置有多个分体支撑杆，第一横杆的上方还设有与其平行的顶支撑杆，顶支撑杆的端部设置有端头撑杆，端头撑杆连接在第一横杆上，顶支撑杆上滑动穿设有与其垂直的预拉丝杆，预拉丝杆相对顶支撑杆背向第一横杆一侧的杆身上螺纹连接有第一螺母，预拉丝杆相对顶支撑杆朝向第一横杆一侧的杆身上依次设置有多个预拉组件，预拉组件包括两个拉杆，每个拉杆均连接于一个分体支撑杆。本申请具有提高桁架使用寿命的优点。
