Construction method of controlling slope and thickness of sloping roof and guide rail device

Abstract

The invention provides a guide rail device, and is applied to cast-in-place concrete of a sloping roof. The guide rail device comprises a sloping roof formwork, plate bottom steel bars, plate surface steel bars, a guiding guide rail, a guide rail support and cushion blocks. The plate bottom steel bars are laid on the sloping roof formwork. The multiple cushion blocks are arranged between the plate bottom steel bars and the sloping roof formwork. The plate surface steel bars are arranged on the upper portion of the plate bottom steel bars. The plate surface steel bars are fixed on the plate bottom steel bars through a bracket. The guiding guide rail is placed on the upper portion of the plate surface steel bars. The guiding guide rail is fixed on the plate bottom steel bars or / and the plate surface steel bars through the guide rail support. The elevation of the guiding guide rail is the elevation of the concrete surface. The invention further relates to a construction method of controlling slope and thickness of the sloping roof. According to the construction method of controlling the slope and thickness of the sloping roof and the guide rail device, the roof forming quality can be guaranteed, rework and secondary leveling are avoided, the construction period, material cost and labor cost are saved, and the construction difficulty is reduced; and the phenomenon of seepage of roofing is avoided, and the loss to an owner is not caused.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a construction method and a guide rail device for controlling the slope and thickness of a sloping roof. Background technique [0002] In recent years, my country's construction industry has made great leaps in terms of technical level and construction quality. The traditional flat roof of the building has gradually been replaced by sloping roof due to its backward thermal insulation performance. In architectural design, there are many novel and colorful sloping roof structures, which add different colors to the functions of houses. However, it should not be ignored that the rise of sloping roofs has also brought certain influence and hidden dangers to the quality of roof construction. [0003] The construction of the cast-in-place concrete sloping roof is difficult, and the overall construction quality is difficult to control, and many construction difficulties are prone to qu...

AI Technical Summary

Problems solved by technology

[0009] (1) The method of measuring the elevation of the concrete slab with red paint on the steel bar head has a large error, and it is difficult to accurately control and inconvenient to operate during the pouring process

[0010] (2) The vibration process is likely to cause a large amount of concrete flow, and it is difficult to ensure the compactness of the concrete
