Description

A prefabricated bay window unit component, prefabricated bay window and construction method

technical field

The invention belongs to the technical field of prefabricated architectural design, and in particular relates to a prefabricated bay window unit component, a prefabricated bay window and a construction method.

Background technique

The bay window is a very common window sill in existing houses. The bay window is generally rectangular or trapezoidal and protrudes to the outside, with glass on one or three sides. Not only is it beautiful in appearance, but also has a higher utilization rate of resources. With the vigorous development of prefabricated buildings, prefabricated walls are used more and more in prefabricated buildings. The existing technology is mainly to prefabricate the bay window and the whole prefabricated wall body together, the production efficiency of the factory is low, and the large volume and weight of the components make the on-site installation difficult and costly.

Chinese utility model patent CN 206655311U discloses a prefabricated assembled reinforced concrete bay window component, including two symmetrically arranged side windows, a roof window connected to the top of the two side windows, and a window sill connected to the bottom of the two side windows. The two side windows and the inner side of the top window are equipped with steel bars, and the bay window components are connected with the cast-in-place wall beams through the steel bars to form a whole during installation. Steel bars protrude from three sides of this component, which will easily affect the binding of steel bars in the shear wall and affect the construction progress.

Chinese utility model patent CN 204174731U discloses a combined reinforced concrete prefabricated bay window, which is surrounded by two side baffles and a front end baffle to form a unit member with a groove, and a pre-embedded connector extending inward is arranged in the groove During installation, the two unit components are fixed with the corresponding upper and lower floor cast-in-place beams through the embedded connectors, thus forming a bay window. The prefabricated bay window has many connection methods, the operation is complicated, and the quality of the connection points is difficult to control.

Moreover, both of the two prefabricated bay windows disclosed above cannot be used as air-conditioning panels, and the resource utilization rate and practicability are lower than those of cast-in-place bay windows.
