Bare concrete bay window steel formwork structural body device

Abstract

The invention relates to a bare concrete bay window steel formwork structural body device. The bare concrete bay window steel formwork structural body device is characterized in that an under-window inner formwork and an under-window outer formwork are connected with main formworks commonly used for an inner wall and an outer wall through assembling holes, and a lower suspension bottom formwork and the under-window outer formwork can be directly assembled through corner connecting pieces; one side face of a window inner formwork and one side face of a window outer formwork are connected with the inner wall main formwork and the outer wall main formwork on the two sides of a window respectively; the bottom edges of two bay window aperture formworks are hung in the air to be at the same height as the lower side of the window inner formwork, and are connected with the other side face of the window inner formwork and the other side face of the window outer formwork respectively; an upper suspension bottom formwork, a window beam bottom formwork and window beam inner formworks are connected and assembled; the window beam inner formworks and window beam outer formworks are oppositely pulled to be fixed through screw rod sleeves; the window beam inner formworks, the window beam outer formworks, the window beam bottom formwork and the upper suspension bottom formwork are connected with the main formwork commonly used for the outer wall and a connection formwork on the upper portions of the bay window aperture formworks. The device has the advantages of being simple in structure, convenient to assemble and capable of reducing labor and cost; concrete can be successfully poured at a time to form a whole structural body, the anti-seismic effect is enhanced, and construction quality is improved; the steel formwork is high in university and capable of meeting various structural requirements.

Description

technical field [0001] The invention relates to building construction equipment, in particular to a steel formwork structure device for clear-water concrete bay windows. Background technique [0002] The construction of bay windows has always been relatively complicated. In the past, wooden formwork was used most often for construction. However, due to the complexity of construction, the quality is often not guaranteed, and there are many deviations, which cannot meet the construction requirements. The construction quality defects of bay windows need to be repaired and covered by decoration, the structural strength is poor, and a lot of labor is wasted; aluminum alloy formwork, national standard steel formwork and all-steel large formwork have not been seen to make bay windows, and no such literature reports have been seen , For this reason, be badly in need of developing a kind of practical tool that can improve bay window construction quality, and reduce labor cost.
