Pre-tensioning type pipe truss
The invention provides a pre-tensioning type pipe truss, and belongs to the technical field of truss components. Comprising a main pipe and two branch pipes, a triangular shape is formed between the two branch pipes and the main pipe, a plurality of branch nodes are arranged on the main pipe at intervals, two pre-tightening units are formed between the branch nodes and the two branch pipes, and each pre-tightening unit comprises two pull pipes connected with the branch nodes and the branch pipes respectively and a cable penetrating transverse pipe connected with the two branch pipes. The two pull pipes and the cable penetrating transverse pipe corresponding to the pre-tightening unit are located in the same plane. Each branch node comprises a sleeve arranged outside the main pipe in a sleeving manner and two adjusting heads symmetrically distributed in the sleeve, the adjusting heads are in threaded connection in the sleeve, the adjusting heads are connected outside the main pipe in a sliding manner, the inner ends of the adjusting heads are provided with conical adjusting parts, and the adjusting parts are provided with spiral guide rope grooves; the two ends of the inhaul cable are fixed in the cable penetrating transverse pipe, the inhaul cable is arranged in the hollow cavities of the cable penetrating transverse pipe and the branch pipes in a penetrating mode, and the inhaul cable is provided with at least one complete winding circle on the adjusting part cable guide groove. The invention has the advantages of high strength and the like.
本发明提供了一种预拉式管桁架，属于桁架构件技术领域。包括一根主管和两根分管，两根分管与主管之间呈三角状，主管上相间设置若干分支节点，分支节点与两根分管之间形成两个预紧单元，预紧单元包括两根分别连接分支节点与分管的拉管和连接两根分管的穿索横管，预紧单元对应的两根拉管和一根穿索横管处于同一平面内；分支节点包括一根套设在主管外的套管和对称分布在套管内的两个调节头，调节头螺纹连接在套管内，调节头滑动连接在主管外，调节头的内端具有一锥形的调节部，调节部上具有螺旋状的导索槽；拉索的两端部固定在穿索横管内，拉索穿设在穿索横管和分管的中空腔内，拉索在调节部导索槽上至少有一个完整的绕圈。本发明具有强度高等优点。
