Cantilever bay window board concrete overall pouring structure and construction method thereof

Abstract

The invention provides a cantilever bay window board concrete overall pouring structure and a construction method of the cantilever bay window board concrete overall pouring structure. An upper bay window board is formed together with an above-window coupling beam and an upper layer floor through concrete overall pouring, and the inner end of an upper bay window board reinforcing steel bar of the upper bay window board extends into the above-window coupling beam to be anchored. A lower bay window board is formed together with the upper portion of a below-window coupling beam through concrete overall pouring, and the inner end of a lower bay window board reinforcing steel bar of the lower bay window board extends into the below-window coupling beam to be anchored. According to the cantilever bay window board concrete overall pouring structure and the construction method, the positions of the bay window boards are reserved in the construction process of a concrete wall, the upper bay window board and the above-window coupling beam are simultaneously formed together with the upper layer floor through pouring, the lower bay window board and the upper portion of the below-window coupling beam are simultaneously formed through pouring, the integrity is good, cracks of the root portions of the bay window boards are effectively eliminated, leakage and potential safety hazards caused by the cracks are effectively eliminated, later-period maintenance and processing expenses of a bay window are reduced, and the cantilever bay window board concrete overall pouring structure and the construction method can be widely applied to non-floor type bay window construction of a cast-in-place concrete shear wall structure house.

Description

technical field [0001] The invention relates to a cast-in-situ concrete cantilever bay window structure and a construction method thereof. Background technique [0002] In order to pursue the permeability of the architectural living room, form a wide viewing space, and improve the livable quality of urban residences, bay windows, as a special architectural design form, are more and more widely used in residential projects. The upper and lower slabs of the bay window are cast-in-situ concrete cantilevered structures. Traditional construction methods generally use the horizontal steel bars reserved or pre-embedded for the cantilevered slab during wall construction. After the wall concrete is poured, the cantilevered components are poured separately. figure 1 shown. This kind of construction technology has problems such as inaccurate location of pre-embedded steel bars, repeated bending of horizontal steel bars, vertical construction joints left at the root of the slab, and ...
