Super-large-span roof steel truss and high-altitude floor support-free construction method
The invention belongs to the technical field of building material preparation, and particularly provides a super-large-span roof steel truss which comprises a roof structure and a floor plate, wherein the roof structure is formed by combining a plurality of single trusses. High-altitude floor support-free construction of the ultra-large-span roof steel truss comprises the following steps: S1, conducting preparation before installation; conducting pre-embedding of steel structure embedded parts in the upper-layer structure civil engineering professional steel bar binding process; and after concrete pouring is completed and the maintenance strength meets the requirement, hoisting two 10-ton forklift trucks to a floor plate through a 100-ton truck crane; laying a 2cm steel plate on a floor plate to serve as a temporary road; and hoisting the two 25-ton truck-mounted cranes and the four 50-ton crawler cranes to the floor plate by combining the 200-ton truck-mounted cranes, wherein all hoisting equipment can conduct construction on an upper floor, so that the installation difficulty of the roof super-large-span truss is lowered, and the construction period is shortened.
本发明属于建筑材料制备技术领域，具体而言，本发明提供了一种超大跨度屋面钢桁架，包括屋顶结构和楼层板，屋顶结构由多个单榀桁架组合而成，一种超大跨度屋面钢桁架的高空楼面无支撑施工，包括以下步骤：步骤S1、安装前准备、在上层结构土建专业钢筋绑扎过程中穿插钢结构埋件的预埋，混凝土浇筑完成养护强度满足要求后，采用100吨汽车吊将两台10吨叉车吊至楼层板，本发明通过100吨汽车吊将两台10吨叉车吊至楼层板，并在楼层板铺设2cm钢板作为临时道路，并结合200吨汽车吊将两台25吨汽车吊及4台50吨履带吊吊至楼层板，从而使得各吊装设备能够在上层楼面进行施工，从而降低了屋顶超大跨度桁架的安装难度，从而缩短工期。
