Method for building telescopic truss mechanism and truss mechanism
The invention relates to the technical field of mechanical structure construction in the field of spanning buildings and machinery, in particular to a construction method of a telescopic truss mechanism. A fixed upper chord and a movable upper chord are restrained and limited by a slide way structure, and the fixed upper chord and the movable upper chord only move according to the fact that the fixed upper chord and the movable upper chord are restrained in a needed threshold value track or within a needed threshold value range through relative displacement between the fixed upper chord and the movable upper chord; the lower chord member is connected with at least two inclined chord members in a hinge manner, a group of upper chord members with at least one group are connected to the connected inclined chord members in a hinge manner, and the lower chord member is additionally connected with at least two inclined chord members in a hinge manner; and at least one second group of upper chords are connected to the connected inclined chords in a hinge manner to form a hinge structure. The mechanism has the advantages of light truss structure, low steel consumption, simple stress system and high construction speed, and has the capability of completely replacing the truss structure after being completely unfolded; the mechanism has the advantages of small concentrated stress, unlimited telescopic proportion and the like, and can be used for partially replacing a slideway in the prior art.
本发明涉及一种跨越建筑与机械领域的机械结构组建技术领域，一种可伸缩桁架机构的组建方法：定上弦杆、动上弦杆受滑道结构约束限制，两者之间的相对位移使其仅按照被约束在所需阈值轨迹或所需阈值范围内移动；下弦杆以铰链方式连接数量至少为2的斜弦杆，并且在被连接的斜弦杆上以铰链方式连接数量至少为1的一组上弦杆，下弦杆另外以铰链方式连接数量至少为2的斜弦杆，并且在被连接的斜弦杆上以铰链方式连接数量至少为1的第二组上弦杆共同组成铰链结构。本机构顾桁架结构轻盈、用钢量省、受力体系简单、建设速度快优点，完全展开后具备完全替代桁架结构的能力；本机构还有集中应力小、伸缩比例不受限等优点，可用于部分替代现有技术滑道。
