Inverted cone jacking method for large-span net rack structure
The invention provides an inverted cone jacking method for a large-span net rack structure. The method comprises the following steps of A, arranging a supporting rack on the ground, and splicing threelayers of arc-shaped net racks from bottom to top in sequence on the supporting rack; B, mounting a jacking support at the free end of the spliced lowermost net rack; C, arranging a jacking device below the jacking support and enabling the jacking portion of the jacking device to make contact with a first ball node of the jacking support; D, jacking the net rack by the jacking device through thejacking support; E, after the free end of the net rack is jacked by a certain height, continuing to conduct splicing along the free end of the net rack, reserving positions for mounting the jacking support and placing the jacking device below the free end lowermost net rack newly formed by the net racks; F, repeating the steps B to D until the whole net rack is spliced; and G, after the whole netrack is spliced, arranging a mounting support on the ground, and fixing a ball node at the free end of the net rack to the mounting support. The method enables simple and convenient construction and is easy to implement.
本发明提供了一种大跨度网架结构倒锥顶升方法，其步骤包括a、在地面上设置支撑架，在支撑架上从下至上依次拼接三层弧形的网架；b、在拼接好的最下层网架的自由端上安装顶升支架；c、在顶升支架的下方设置顶升装置，并使顶升装置的顶升部位与顶升支架的第一球节点接触；d、使用顶升装置通过顶升支架将网架顶起；e、当网架的自由端被顶起一定的高度后，沿着网架的自由端继续拼接，并在网架新形成的自由端最下层网架的下方留出安装顶升支架和放置顶升装置的位置；f、重复步骤b至步骤d，直到整个网架拼接完毕；g、当整个网架拼接完毕后，在地面设立安装支座，并将网架自由端的球节点固定在安装支座上。本发明施工简便，易于实现。
