Method for installing and removing a construction operation platform for a rooflight resting on a main beam

Abstract

The present application relates to the technical field of building construction, and particularly relates to a method for installing and removing a main beam resting type daylighting roof construction operation platform, comprising the following steps: S1, marking the opening center line position; S2, cutting the opening in the parapet wall; S3, installing the auxiliary cross beam on the parapet wall; S4, installing the main beam; S5, moving the auxiliary cross beam to the installation position of the next main beam; S6, the end portions of the plurality of main beams are fixed by welding the second angle steel; S7, a plurality of secondary beams are arranged between the two adjacent main beams; S8, the double-layer protection system is laid on the main beam; S9, the three-stage loading pretest is implemented; S10, the platform covering layer is removed; S11, the main beam and the auxiliary beam are synchronously separated along the axial direction, and the remaining main beams are sequentially removed. The method does not need to occupy other operation surfaces in the building, is beneficial to flexible arrangement of the site, and the material consumption is far lower than that of the traditional scaffold, so that the cost is effectively reduced. The installation and fixing process of the main beam and the main structure is simple, and the construction speed is faster.
