Description
Technical Field
The invention relates to the technical field of construction of a floating window plate, in particular to a construction method of a concrete floating window plate on an outer vertical surface of a building.
Background
The upper and lower plates of the bay window are used as a cast-in-place concrete cantilever structure, and the traditional construction method comprises two steps: firstly, in order to pursue the surface construction progress, the horizontal reinforcing bar of the cantilever plate is reserved on the upper and lower plates of the bay window during wall body construction, and after the wall body concrete pouring is completed, the cantilever member is poured independently, the construction process has the defects that the positions of the embedded reinforcing bars of the upper and lower plates are inaccurate simultaneously, the cross operation and the template reinforcement are still existed in the secondary construction, and the real construction progress is delayed. The construction process is synchronous with the main structure on the same layer, and the construction process is slow due to cross operation at the position; and the lower floating window plate overhanging steel bar is seriously trampled, so that the steel bar protective layer is too large, and the quality defects of the overhanging plate, such as bearing capacity, durability, section size deviation, concrete honeycomb pitted surface, insufficient arching, poor flatness and the like, are overcome.
Therefore, how to quickly finish the construction of the concrete floating window plate on the outer surface of the building with quality and quantity conservation is a technical problem which needs to be solved urgently by technical personnel in the field.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention provides the construction method of the building external facade concrete bay window plate, which effectively accelerates the construction progress, controls the construction quality of each procedure and reduces the construction period pressure.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
a construction method of a concrete floating window plate on the outer facade of a building comprises the following steps:
s1, measuring and paying off, and binding steel bars according to design requirements;
s2, erecting a template on the upper bay window plate, and reserving a lower bay window plate steel bar;
s3, pouring concrete according to the design requirement and maintaining;
s4, removing the formwork after the concrete achieves the formwork removal adjustment;
s5, performing secondary construction on the lower floating window plate;
and S6, after the construction of the lower floating window plate is finished, checking and accepting.
In the step S1, during the construction of the main body structure, measurement and paying-off are carried out in advance, reinforcing steel bars are bound according to design requirements, and the lower bay window plate is pre-stressed with longitudinal reinforcing steel bars.
In the step S2, according to the elevation control line, the upper bay window is supported by a formwork, and the reinforcing steel bars are reserved at the lower bay window plate position, so that the wall body formwork is supported to 150mm below the bay window plates.
In the step S5, after the mould is removed, a control line with the lower elevation of 200mm of the lower bay window plate is guided and measured to the inner wall surface and the outer wall surface of the position, after the stubble connecting part is roughened, the reserved steel bars of the lower bay window plate are aligned and the steel bars are bound according to the design requirement, the support frame is utilized to reinforce the mould plate, and concrete pouring and maintenance are carried out.
In the step S6, after the downward floating window plate reaches the mold removal condition, mold removal and acceptance check are performed.
Compared with the prior art, the method has the beneficial effects that:
go up and waft the luffer boards and construct with the floor is in step, waft the luffer boards down and postpone in the same floor major structure construction, can accelerate the construction progress, control the quality of every process effectively, accomplish the engineering once and become excellent, the later stage maintenance cost that significantly reduces alleviates time limit for a project pressure.
