Fabricated building overhung balcony position external envelope structure

Abstract

The invention relates to a fabricated building overhung balcony position external envelope structure, comprising a vertical prefabricated shear wall; the prefabricated shear wall is provided with a balcony floor slab overhung at the outer side face of the prefabricated shear wall; the outer side face of the prefabricated shear wall is connected with two external protective frames; each external protective frame comprises a horizontal pedal, and the upper surface of each pedal is connected with a vertical forward guard plate; the forward guard plates are flushed with the side faces, far away from the prefabricated shear wall, of the pedals; the two external protective frames are respectively positioned at the two ends of the balcony floor slab; the pedals are flushed with the balcony floorslab; extending protective plates, used for protecting the corresponding ends of the balcony floor slab, extend from the ends, close to the balcony floor slab, of the forward guard plates; a verticalouter protective plate is connected between the two extending protective plates in a detachable way by means of a connecting piece; the outer protective plate is flushed with the overhung side face ofthe balcony floor slab and is used for protecting the outer side of the balcony floor slab. The overhung balcony envelope structure is simpler; the external protective frames and the outer protectiveplate are detachable, so that the construction is facilitated while the safety is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of building protection, and in particular relates to an outer protection structure for the position of an overhanging balcony of a prefabricated building. Background technique [0002] In the construction process of the prefabricated building, the outer protection system can adopt the form of cantilevered scaffolding, floor-standing steel pipe scaffolding, fixed attachment protection frame, integral operating platform, integral attachment lifting protection frame, tool scaffolding and other frame forms . Among them, cantilever scaffolding and floor-standing steel pipe scaffolding are traditional forms, which have disadvantages such as limited height, difficult construction, and excessively large reserved holes in the wall. At present, the tool-type outer protective frame of tool-type scaffolding is more commonly used, and there are relevant standards for use, and there are also related references in the pri...

Problems solved by technology

Among them, cantilevered scaffolding and floor-standing steel pipe scaffolding are traditional forms, which have disadvantages such as limited height, difficulty in construction, and too large reserved holes in the wall.

At present, the tool-type outer protective frame of tool-type scaffolding is commonly used, and there are related standards for use. There are also relevant references in the prior art, such as: CN206376507U, CN108756196A, CN207110421U, CN106677509A, CN108868096A, but the relevant outer protective frames are all connected On the outside of the wall, and connected in a circle on the outside of the wall of the building for use, in the position of overhanging structures such as air-conditioning placement boards and balconies, there is still a lack of corresponding external protection structures. CN106677509A discloses a bay window outside For the structure of the protective frame, the outer protective structure is specially designed for the bay window. In addition, the cantilever, screw, bolt, inverted U-shaped clamp, channel steel and other structures for supporting the outer protective structure are specially designed, and also It needs to be implemented in combination with the special structure of the wall, which is relatively complicated and has poor applicability; in addition, the related outer protective frame still has problems of construction inconvenience and imperfect design considerations; all of them need to be further improved and optimized
