摘要： A dome structure is disclosed, comprising an upper part of a dome structure having a top portion and a bottom portion and being erected on a structure with the bottom portion of the dome frame contacting the structure, the dome structure comprising a plurality of arch-shaped steel trusses, each of which comprises a plurality of upper chord members and a plurality of lower chord members; and at least two pairs of compression rings, each ring in a pair being of a different diameter and being engaged with the top portion of the dome structure, at least the pairs of the compression rings supporting the upper chord members, and one of the rest of the pairs of the compression rings supporting the lower chord members, the steel trusses extending radially from the compression ring to the structure.

摘要： With the conventional radiating truss roof support array, the inner-truss connecting members form multiple complete rings radiating from the central portion of the roof to the periphery at fixed intervals. When tension is applied to the periphery of the roof, a constricting annular compression is generated in each of the concentric rings of inner-truss connecting members. By this mechanism, the tension applied to the periphery is somewhat dissipated, and a less than optimal effect on the curvature of the dome of the roof is achieved for a given amount of tension applied to the periphery. The present invention concerns a radiating truss roof support array constructed in such a manner as to eliminate the above described problem of induced annular constriction in the concentric rings of inner-truss connecting members. This goal is achieved by interrupting the concentric rings of inner-truss connecting members at fixed intervals so that predetermined adjacent trusses are not connected together by the above mentioned inner-truss connecting members. the concentric rings of inner-truss connecting members thus formed are incomplete at predetermined portions and the annular constriction is thus eliminated. Thereby, the tension applied to the periphery of the structure is used to maximum effect in maintaining the curvature of the dome of the roof.
摘要翻译： 使用传统的辐射桁架屋顶支撑阵列，内部桁架连接构件形成从固定间隔从屋顶的中心部分到周边辐射的多个完整环。 当对屋顶的周边施加张力时，在内桁架连接构件的每个同心环中产生收缩的环形压缩。 通过该机构，施加到周边的张力有些消散，并且对于施加到周边的给定量的张力，实现了对屋顶的圆顶的曲率的不太理想的影响。 本发明涉及一种辐射桁架屋顶支撑阵列，其以这样的方式构造，以消除上述在内桁架连接构件的同心环中引起的环形收缩的问题。 该目的通过以固定间隔中断内桁架连接构件的同心环来实现，使得预定的相邻桁架不通过上述内桁架连接构件连接在一起。 如此形成的内桁架连接构件的同心环在预定部分是不完整的，因此消除了环形收缩。 因此，施加到结构的周边的张力用于保持屋顶的圆顶的曲率的最大效果。
