Installation method of large-span arched grid structure
The invention discloses a method for installing a large-span arched grid structure, which comprises the following steps of: firstly, mounting a starting area grid in a cantilever manner, starting assembling on a support on one side of a grid mounting area, firstly completing assembling of four grids of a lower chord and three grids of an upper chord of a first unit, hoisting an upper chord ball at one end by using a crane to hoist the grid away from the ground, and after reaching a certain height, hoisting the first unit to form a second unit; the net rack extends outwards along the lifted end; and then a truck crane is added to repeat the hoisting operation to move outwards, the net rack continues to be extended until the starting net rack is assembled, and then the method that the net rack is extended in a high-altitude bulk mode is adopted. Scaffolds do not need to be erected on site, the net rack occupies a small area of a coal yard during starting installation, does not need to occupy the space of the coal yard for a long time in the construction process, adopts a small amount of large mechanical equipment, is safe and reliable, extends towards the two sides to be installed after the starting area is installed, and can be installed while the installation area is returned to the coal yard to be used. And net rack installation and use in a coal yard are ensured to be neglected.
本发明公开了一种大跨度拱形网架结构的安装方法，用先悬挑安装起步区域网架，在网架安装区域一侧的支座开始拼装，先完成第一单元下弦四个网格、上弦三个网格的拼装，再用吊车吊起一端的上弦球将网架吊离地面，达到一定高度后，将网架沿吊起的一端向外延伸；之后增加汽车吊重复上述吊装操作向外移动，继续延伸网架，直至起步网架拼装完成，再采用高空散装的方式延伸网架的方法。本发明现场不需要搭设脚手架、网架起步安装时占用煤场区域较少，施工过程中不需要长时间占用煤场空间，采用的大型机械设备较少，安全、可靠，而且起步区域安装完成之后向两侧延伸安装，网架可一边安装一边把安装区域退还煤场使用，保证网架安装与煤场使用两不误。
