High-altitude long-span overhung cornice formwork supporting system and constructing method thereof

Abstract

The invention provides a high-altitude long-span overhung cornice formwork supporting system. The system comprises an overhung I-shaped steel beam, an overhung I-shaped steel beam fixing hoop, an anchoring ring, a steel wire rope inhaul cable, an operating platform, an overhung structure load-bearing frame, an outer protecting scaffold, a cornice supporting formwork and a secondary unloading assembly, wherein a pull ring, a vertical rod inserting-connection positioning part and steel angles are arranged on the overhung I-shaped steel beam, one end E of the overhung I-shaped steel beam is fixed to an architectural structure plane through the overhung I-shaped steel beam fixing hoop, the other end of the overhung I-shaped steel beam is tensioned with the steel wire rope inhaul cable, the secondary unloading assembly comprises an inclined-supporting steel tube and a pre-buried supporting point steel tube, and the secondary unloading assembly is used for performing secondary unloading on a cornice supporting formwork system. A constructing method of the high-altitude long-span overhung cornice formwork supporting system includes the steps of manufacturing the overhung I-shaped steel beam, arranging the pre-buried part, installing the overhung I-shaped steel beam, setting up the operating platform, the overhung structure load-bearing frame, the outer protecting scaffold and the cornice supporting formwork, installing the inclined-supporting steel tube and the like. The high-altitude long-span overhung cornice formwork supporting system is easy to construct and operate and convenient to detach, the construction period is shortened, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of construction of high-altitude and large-span cantilevered cornices in buildings, in particular to a formwork support system for high-altitude and large-span cantilevered cornices and a construction method thereof. Background technique [0002] With the pursuit of individuality and visual effects in modern architectural design, high-rise buildings often set cantilevered cornices on the top and outer walls of the building to meet the needs of functional and beautiful appearance. Such as figure 1 As shown, in the superstructure of a high-rise building with high-altitude and large-span cantilevered cornices, it includes a roof surface 101, a shear wall 102, a first layer 103 under the roof surface, a second layer 104 under the roof surface, and a third floor under the roof surface. storey 105 and overhanging cornice 100. The cantilevered eaves 100 are built on the upper outer wall of the shear wall 102 of t...

AI Technical Summary

Problems solved by technology

This kind of floor support frame system and construction method requires a lot of manpower to build and dismantle, and requires a lot of building materials and labor. The construction is complicated and cumbersome, the project cost is high, the construction period is long and the construction safety is not high.
