Building facade concrete bay window board construction method

Abstract

The invention relates to the technical field of bay window board building construction, in particular to a building facade concrete bay window board construction method. The method comprises the stepsof S1, performing surveying and setting out, wherein reinforcing steel bars are bound according to the design requirement; S2, erecting a formwork on an upper bay window board, and reserving lower bay window board reinforcing steel bars; S3, pouring concrete according to the design requirement for maintenance; S4, after the concrete meets the requirement for formwork disassembling, performing formwork disassembling; S5, performing secondary construction on a lower bay window board; S6, after construction of the lower bay window board is completed, performing acceptance inspection. When the body structure is constructed, the building facade upper bay window board and floors are synchronously constructed, reinforcing steel bars are reserved for the lower bay window board, and construction is performed after the formwork of the same layer is disassembled. According to the method, the construction progress can be accelerated, the quality of each procedure is effectively controlled, a project can be excellent at a time, the later maintenance cost is greatly lowered, and the pressure of the time limit for the project is relieved. The method is mainly applied to the aspect of building facade bay window board construction.

[0002] The upper and lower slabs of the bay window are cast-in-place concrete cantilevered structures. There are two traditional construction methods: one is to pursue the surface construction progress. When using the wall construction, all the upper and lower slabs of the bay window are reserved for the horizontal steel bars of the cantilever slab, and the concrete pouring of the wall is completed. Afterwards, the cantilevered components are poured separately. In this construction process, the positions of the pre-embedded steel bars on the upper and lower slabs are inaccurate, the secondary construction still has cross operations, the formwork reinforcement is complicated, and the real construction progress is lagging behind.

The second is to construct synchronously with the main structure of the same floor. Due to the cross-operation here, the construction progress is slow; and the overhanging steel bars of the lower bay window panels are seriously trampled, resulting in too large a protective layer of steel bars, which reduces the bearing capacity and capacity of the cantilevered slabs. Quality defects such as durability, cross-sectional size deviation, concrete honeycomb pitting, insufficient arching, and poor flatness
