Mounting and demounting method of demountable and mountable overall hoisting protective frames

Abstract

The invention discloses a construction method of demountable and mountable overall hoisting protective frames. The construction method comprises the following steps that a plurality of protective frame units are prepared, and each protective frame unit comprises a prefabricated wallboard and the corresponding protective frame connected with the prefabricated wallboard; the protective frame units on the first layer are hoisted, and the protective frames at the first layer are reinforced; the second step is repeated, the prefabricated wallboards on the second layer and the third layer are hoisted sequentially and fixed to the edges of a prefabricated floor slab on the second layer and the edges of a prefabricated floor slab on the third layer correspondingly; the protective frames are demounted; the protective frames conveyed to the ground are connected with the prefabricated wallboards according to the method in the first step, then the second step is repeated to hoist the prefabricatedwallboards of the mounted protective frame units to the edges of a prefabricated floor slab on the fourth layer, and the prefabricated wallboards and the prefabricated floor slab on the fourth layerare mounted and fixed; and when the hoisting conditions of the prefabricated wallboards on the previous layer are achieved, the protective frames located on the lowermost layer are demounted accordingto the fourth step and hoisted to the ground. By adopting the construction method of the demountable and mountable overall hoisting protective frames, the stability of joists on the outer side is improved, and operation is quite easy and fast.

Description

technical field [0001] The invention relates to a construction method for an outer eave protective frame body of a fully assembled residential project, in particular to a method for installing and dismounting a detachable integral hoisting protective frame body. Background technique [0002] At present, with the promotion of the country and the support of policies, the construction industry has entered the era of rapid development of prefabricated buildings. Due to the gradual increase in the design height of fully prefabricated houses, the traditional protective frame can only be erected up to 50 meters. Since the prefabricated building wall panels are all prefabricated, there is no space for the cantilevered frame to be erected on the outer eaves. For buildings over 50 meters The building cannot use the traditional frame for construction, so the traditional protective frame can no longer meet the construction requirements of the prefabricated building.
