Improved supporting system construction method suitable for large overhung outer floating plate roof

Abstract

Provided is an improved supporting system construction method suitable for a large overhung outer floating plate roof. A technological process comprises the steps of erecting a double-row ground standing type steel pipe scaffold, adding frame body supporting oblique rods and horizontal suspension rods, performing frame body strengthening treatment, arranging horizontal rod supporting rods, strengthening fasteners, arranging connecting wall rods, erecting an overhung parapet wall floating plate bottom cast support, performing stability checking calculation and performing supporting acceptance inspection. The formwork supporting system bearing requirement is achieved by performing strengthening treatment on an original outer scaffold system for construction and erecting an outer overhung bearing platform, normalized construction is quickly and rapidly achieved, the improved supporting system construction method is economic, safe and reliable, erection and demolition are convenient and flexible, revolving materials are saved, the construction efficiency is remarkably improved, and a construction period is obviously shortened. A series of complicated processes for a supporting system and the like used for ground formwork erection by adopting a traditional construction method are well avoided, and materials and labors are greatly saved, and the construction period is shortened.

Description

technical field [0001] The invention relates to IPC international patent classification E04B general building construction technology, in particular to an improved support system construction method suitable for large overhanging external floating board roofs. Background technique [0002] In the single construction of some ancient-style buildings, floating slabs with a length of more than 2m above the top of the parapet are often encountered, which belong to super-long slabs. The support height of this type of slab is relatively high during construction, and it is difficult to support the formwork. However, if the original scaffolding is removed and the vertical support frame is erected on the ground again, more materials, labor and time will be consumed. [0003] The parapet refers to the low wall around the roof of the building. In addition to maintaining safety, the main function is to apply waterproof pressure bricks to the bottom to prevent water seepage from the water...
