Round coal yard net rack construction technology
The invention relates to a circular coal yard net rack construction technology which comprises the following specific steps of S1, preparation work before installation, S2, net rack starting unit installation operation, transition plate installation, blocky net rack splicing, blocky net rack hoisting, blocky net rack fixing and blocky net rack air butt joint operation are conducted in sequence, and S3, follow-up net rack installation is conducted. After the block-shaped net rack is closed, high-altitude bulk packing of the net rack is carried out, namely from a second ring belt of an upper chord of the net rack, an upper chord small assembly unit is firstly mounted by adopting a crane, when the upper chord small assembly unit is mounted to a 1/4 ring belt, another crane is added to start to mount a lower chord small assembly unit, and the whole spherical shell is completely mounted in a ring-by-ring closing manner in the circumferential direction; s4, mounting operation of purlins is conducted, specifically, bracket mounting, main purlin mounting and secondary purlin mounting are conducted in sequence; S5, color plate mounting is conducted; detailed operation steps are provided for specific hoisting operation of the spherical net rack, and safety and working efficiency during installation operation of the spherical net rack are improved.
本发明涉及一种圆形煤场网架施工工艺，该方法具体步骤如下：S1：安装前准备工作，S2：网架起步单元安装操作，依次进行过渡板安装、块状网架拼装、块状网架吊装、块状网架固定和块状网架空中对接操作，S3：后续网架的安装，块状网架合拢完成后即进入网架的高空散装，高空散装即从网架的上弦第二个环带开始，先采用一台吊车安装上弦小拼单元，当安装至1/4环带时，再增加一台吊车开始安装下弦小拼单元，如此环向逐圈闭合安装至整个球壳全部完成，S4：檩条的安装操作，依次进行支托安装、主檩安装和次檩安装，S5：彩板安装；为球形网架的具体吊装操作提供了详细的操作步骤，提升了球形网架安装操作时的安全性和工作效率。
