Steel structure curved surface skylight frame and construction method thereof
The invention discloses a steel structure curved surface skylight frame and a construction method thereof. The curved surface skylight frame is of a truss structure composed of a curved surface skylight top and box type section stand columns (1) installed and welded to the lower portion of the curved surface skylight top. The curved skylight top is composed of a net-shaped structure and an annular edge sealing beam (3), wherein the net-shaped structure is formed by installing and welding a plurality of trapezoidal-section rod pieces through a plurality of nodes (2), and the annular edge sealing beam (3) is installed and welded to the periphery of the curved skylight top. The trapezoidal cross-section rod piece comprises a main chord member (4), a thickened node (5) and a secondary chord member (6); the cross sections of the two ends of the main chord member (4) are trapezoidal; the construction method comprises the following steps: installing and welding semi-finished trapezoidal cross-section rod pieces, butting and installing and welding the main chord members and the thickened nodes, integrally pre-splicing, and sequentially installing the secondary chord members, the annular edge sealing beams and the box-type cross-section upright posts according to a ground sample coordinate control network. The manufacturing method is simple, the construction precision is high, lighting and ornamental value are achieved, butt joint and welding deformation is effectively controlled through sequential tailor welding, and the construction quality and the construction efficiency are improved.
本发明公开了一种钢结构曲面天窗架及其施工方法，所述曲面天窗架为曲面天窗顶和组焊在曲面天窗顶下部的箱型截面立柱（1）组成的桁架结构；所述曲面天窗顶由若干个梯形截面杆件通过若干个节点（2）组焊成的网状结构和组焊在所述曲面天窗顶外围的环形封边梁（3）组成；所述梯形截面杆件包括两端截面均为梯形的主弦杆（4）、加厚节点（5）、次弦杆件（6）；其施工方法包括组焊半成品梯形截面杆件、主弦杆与加厚节点对接组焊、整体预拼、根据地样坐标控制网依次安装次弦杆、安装环形封边梁、安装箱型截面立柱；本发明的制作方法简单、施工精度高、兼具采光和观赏性，本发明采用的按序拼焊有效控制了对接和焊接变形，提高了施工质量和施工效率。
