Problems solved by technology
Due to the large slope of the sloped roof, the fluidity of the concrete, and the large area during pouring, these problems are difficult to solve by traditional pouring methods
In addition, when the traditional method is used for construction, the construction personnel on the inclined roof lack a foothold, and there are potential safety hazards

Embodiment Construction
[0011] like figure 1 As shown, the present invention divides the large roof 2 into several small surfaces by using the compartment bar 1 on the base of the large roof. The spacing of each compartment bar is set according to the slope of the inclined roof. The spacing of the bars should be 0.9m; the spacing of each section of the sloping roof with a slope of 30°~45° should be 0.8m; the spacing of each section of the sloping roof with a slope of more than 45° should be 0.6m. After the strength of the sub-bars meets the requirements, the pouring of the fine stone concrete on the inclined roof can be carried out from top to bottom.

The invention relates to concrete pouring for sloping roofs, in particular to a pouring method for fine aggregate concrete steps of a sloping roof. The pouring method for the fine aggregate concrete steps of the sloping roof comprises the steps that annular bin separation strips are arranged around the rooftop on the sloping roof before pouring construction, and fine aggregate concrete pouring is performed on the sloping roof from top to bottom after the strength of the bin separation strips meets requirements. According to the pouring method for the fine aggregate concrete steps of the sloping roof, the flatness of poured fine aggregate concrete is effectively guaranteed, and a standing place can be provided for constructors.
Description
technical field [0001] The invention relates to concrete pouring for sloped roofs, in particular to a method for pouring fine stone concrete for sloped roofs. Background technique [0002] With the development of housing construction and the spread of urban building flat-to-slope projects, the roofs of most buildings are now sloped roofs, and the quality of fine stone concrete on sloped roofs during the construction process has become the key object of process acceptance. It plays a particularly important role in the sloping roof system, and also plays a connecting role in the structure of the roof system: for the bottom, the waterproof membrane must be protected, which is related to the service life of the waterproof membrane; for the upper, it must be used as a tile roof. Construction of the base layer; this requires quite high requirements for the flatness control of the fine stone concrete protective layer on the sloped roof. Due to the large slope of the inclined roof,...
