Integrally-prefabricated U-shaped bay window component and fabricated bay window joint structure and construction method thereof

Abstract

The invention discloses an integrally-prefabricated U-shaped bay window component and a fabricated bay window joint structure and a construction method thereof. The integrally-prefabricated U-shaped bay window component is formed by first, second and third plates, the upper portion of the second plate forms a boss relative to the lower portion, the boss projects towards the inner side of the second plate, a plurality of grouting sleeves are pre-embedded into the boss, an operating notch is reserved corresponding to each group of the grouting sleeves, and the lower ends of each group of the grouting sleeves extends downwards from the lower end face of the boss. The first plate serves as a bay window bottom plate of an upper floor of two adjacent floors; the upper portion of the second plateserves as a bay window lower wall of the upper floor of the two adjacent floors; the third plate serves as a bay window top plate of the lower floor of the two adjacent floors. On the premise that structure safety of the fabricated bay window joint structure is guaranteed, long special-shaped prefabricated components of bay window joints are avoided, and accordingly production, transporting and hoisting difficulty and cost of each prefabricated part in the fabricated bay window joint structure can be reduced.

Description

technical field [0001] The invention relates to a U-shaped integral prefabricated bay window component, an assembled bay window node structure using the U-shaped integrally prefabricated bay window component, and a construction method for the assembled bay window node structure. Background technique [0002] Construction industrialization is a new business model. With the continuous development of the real estate industry in society, the construction industrialization model has gradually formed with the changes in the construction economy, and prefabricated buildings are becoming more and more popular. In the design of prefabricated structures, although the proportion of large building nodes is relatively small, due to the diversification of its forms, it is easy to lead to the formation of special-shaped prefabricated components, which brings great inconvenience to production, transportation and construction, and also increases costs. . Therefore, on the premise of ensurin...

Problems solved by technology

[0006] First, since the prefabricated part A21 of the structural beam and the top plate A13 of the bay window sill on the lower floor are designed as one prefabricated component, the prefabricated part A21 of the structural beam is a long component, and the top plate A13 of the bay window sill is shorter, which only accounts for the prefabricated part of the structural beam A part of the length of A21, which makes the prefabricated component a long-shaped special-shaped prefabricated component, which increases the difficulty and cost of production, transportation, and hoisting, and the structural beam prefabricated part A21 and the bay window top plate A13 of the lower floor The connection is easily broken and damaged during transportation and hoisting

[0007] Second, since the two prefabricated components are split, they need to be positioned with a supporting structure during construction, and the prefabricated structure composed of the bottom plate A11 of the bay window sill on the upper floor and the lower wall A121 of the bay window sill on the upper floor The component is located on the cast-in-place part A22 of the structural beam, which is neither easy to fix nor easy to construct
