Description

Technical Field

[0001] The present application relates to the technical field of bay window installation, and in particular to a modular prefabricated bay window and a rapid installation system thereof. Background Art

[0002] Bay windows refer to windows that protrude outward on the exterior walls of buildings. They are usually designed to be larger than ordinary windows, and the windowsills are lower, so they can be used as seats. Bay windows not only increase indoor lighting and ventilation, but also provide a place to rest or enjoy the scenery outside. Bay windows are generally rectangular or trapezoidal, protruding toward the outside, and are equipped with glass on three sides. There are two types of bay windows: inner bay windows and outer bay windows. The outer bay windows are convex, while the inner bay windows are flat and concave. The outer bay windows are generally glass windows on three sides, protruding from the wall, and the bottom is suspended in the air. The inner bay windows generally have one side of glass and two sides of walls, which are safer, but they will take up indoor space.

[0003] Prefabricated bay windows refer to transferring a large amount of on-site work in traditional construction methods to the factory. Prefabricated bay windows are processed and manufactured in the factory, transported to the construction site, and installed on site through reliable connection methods. Compared with traditional building forms, prefabricated buildings have great differences in structural forms and construction methods. At the same time, they can improve building quality, reduce construction costs, improve construction efficiency, and enhance environmental protection and energy-saving performance.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the existing prefabricated bay windows are made entirely of reinforced concrete. The prefabricated bay windows are large and heavy in weight, which makes them prone to collision with buildings, making the installation of the prefabricated bay windows more difficult. Summary of the invention
