Description

TECHNICAL FIELD

[0002] With the development of cities, in order to express the style of buildings, the shapes of buildings are various, and various types of slope roof shapes are applied more and more widely. Although the slope roof building shape can express different building styles and has strong aesthetics, the construction of the slope roof is a construction problem.

[0003] The conventional construction method often adopts a reinforced concrete slope roof and eaves, which has many shortcomings. First, because the cross section is inclined, a non-conventional formwork system needs to be set up, the formwork rod is not in accordance with the module, the scaffold steel pipe needs to be cut, so the material loss is large, the economy is poor, and a long time is spent. Second, the concrete pouring has great construction difficulty due to the slope problem, and is prone to form quality problems such as construction cold joints, and the forming quality of the eaves gutter construction is difficult to control. Third, the cast-in-place slope roof eaves form, the forming quality is difficult to control, and the overall forming effect of the outer facade is affected. Finally, the slope roof eaves and the gutter are mostly picked out of the building contour line, and the safety protection risk is great during construction. The operating personnel often have low efficiency, high safety risk and other shortcomings during operation. These shortcomings directly lead to the defects of high cost, long construction period and high safety risk of the slope roof construction, and do not meet the construction concept of low carbon and high efficiency in modern society.
