Description

Technical Field

[0001] The utility model relates to a precast concrete bay window, belonging to the field of precast concrete component design. Background Technique

[0002] Compared with cast-in-situ concrete, precast concrete components produced in factories have many advantages: the relatively stable working environment in factories has a higher safety factor than the complex construction site operations; the quality and technology of building components can be better controlled through mechanized production; the standardization of precast component sizes and characteristics can significantly accelerate the installation speed and construction progress of building projects; compared with traditional on-site formwork, the molds in factories can be reused in cycles, and mechanized production requires less manual labor. With the continuous increase of labor costs, the cost advantage of precast components produced on a large scale will become more obvious. The on-site operation volume of construction sites using precast components is significantly reduced, and the dust pollution and noise pollution are significantly reduced.

[0003] The existing precast concrete bay window is transported to the construction site after being prefabricated in the factory. The precast concrete bay window is assembled with the shear wall. Using the precast concrete bay window helps to improve the construction efficiency. Since the precast concrete bay window needs to be assembled after arriving at the construction site, there is a construction gap formed by the assembly of the upper end of the precast concrete bay window and the wall. The construction gap is prone to water seepage and leakage problems when it rains.

[0004] In summary, there is a technical problem that the construction gap generated during the assembly construction of the existing precast concrete bay window is prone to water seepage and leakage when it rains. Summary of the Invention
