Concrete construction method for large-slope inclined roof

Abstract

The invention relates to a building construction method, in particular to a concrete construction method for a large-slope inclined roof. The method comprises the following steps that S1, bottom formworks and supporting frames of the inclined roof are constructed; S2, steel bars of the inclined roof are bound; S3, face formworks of the inclined roof are arranged and installed; S4, concrete is poured; and S5, the concrete is cured. According to the concrete construction method, the construction efficiency of pouring and vibrating of the concrete is improved, the non compaction and internal damage caused by concrete sliding is reduced, and the quality common disease in concrete pouring of the large-slope roof is overcome; the good inclined roof concrete forming quality creates good construction conditions for subsequent construction procedures (waterproof and hanging) of roof engineering; and the leakage hidden danger left in construction of the conventional inclined roof concrete structure is overcome, the concrete forming quality is ensured, and the construction period delay and the economic loss thereof caused by reworking repair due to structural leakage are avoided.

Description

technical field [0001] The invention relates to a building construction method, in particular to a concrete construction method for a large-slope inclined roof. Background technique [0002] In recent years, a large number of civil buildings have adopted sloped roof design. Sloped roofs can not only effectively prevent seepage and leaks, heat insulation, smooth drainage, and improve the living environment on the top floor; The roofs of these buildings generally have the characteristics of steep slopes, large spans, high requirements for formwork support, difficult construction on inclined operating surfaces, and difficult control of concrete construction quality. [0003] There are usually two methods for the existing steep slope roofs: one is the single-sided formwork method, which is more commonly used, but the compactness of the concrete is difficult to control, and it is prone to pitting and exposed tendons, resulting in common quality problems such as roof leakage; On...

Problems solved by technology

The roofs of these buildings generally have the characteristics of steep slopes, large spans, high requirements for formwork support, difficult construction of inclined operation surfaces, and difficulty in controlling the quality of concrete construction.

[0003] There are usually two methods for the existing steep slope roofs: one is the single-sided formwork method, which is more commonly used, but the compactness of the concrete is difficult to control, and it is prone to pitting and exposed tendons, resulting in common quality problems such as roof leakage; One is the overall double-sided formwork method. Due to the small thickness of the slab (generally only 100mm), the intermediate gap is less than 50mm after removing the steel bars and protective layers. Quality problems such as honeycombs and dog holes are prone to occur when in place, and the construction cost is relatively high
