Common beam and slab formwork arch camber construction method
The invention discloses a common beam and slab formwork arch camber construction method. The method comprises the following steps of (1) an arch camber method and (2) selection of arch camber values. In the step (1), for the common beam and slab structure of a concrete horizontal member, a beam is calculated according to the clear span between supports, and a slab is calculated according to the clear span of short edges; in the step (2), the arch camber values can be 2-4 mm according to the size of the span, or can be wholly lifted according to 0.03%-0.05% of the span. According to the common beam and slab formwork arch camber construction method, the arch camber method and the arch camber values are more scientific, through engineering applications, the deflection of a concrete horizontal structure can be effectively controlled, the forming quality of the concrete horizontal structure is improved, and rework waste is reduced.
