Concrete secondary formwork construction method with ultra-large area

Abstract

The invention relates to concrete construction, and provides a concrete secondary formwork construction method with an ultra-large area. The method comprises the steps of concrete wall construction joint division and segmented construction; first construction segment reinforced steel bar binding and template installing; installation of the template at the construction joints, casting of concrete;form removing; pasting of double-faced adhesive tape at the external rims of primary-casting concrete, casting of concrete for the secondary construction stage after the template for the second construction stage is installed, and completion of the construction of the whole concrete wall through the circulation. First construction segment reinforced steel bar binding and template installing comprises the steps of bonding reinforced steel bars and installing the template in front of the construction joints. The installation of the template at the construction joints comprises the steps of 1, arranging a through wood beam inside the upper opening of the template in the horizontal direction in the horizontal construction joints, and fixing the wood beam with the template through steel nails;2, arranging a through wood beam inside the template in the vertical direction in the vertical construction joints, and fixing the wood beam with the template through steel nails. Casting of concretecomprises the step of casting concrete and conducting vibrating and closely compacting according to design requirements. Form removing comprises the steps of removing the template and the wood beam atthe construction joints after concrete casting maintenance is completed, and reserving split bolts at the construction joints; The concrete secondary formwork construction method with the ultra-largearea has excellent appearance quality.

Description

technical field [0001] The invention relates to concrete construction, in particular to a super-large-area concrete construction method. Background technique [0002] In the field of concrete construction, the so-called super large area refers to the concrete walls of large buildings such as basements and pools. These structures often have super-long, super-high concrete exterior walls, which are also among the structures most prone to quality problems. Due to the effect of internal and external factors, concrete structures inevitably have appearance defects, and construction joints are the parts with the most frequent appearance defects of super-long and super-high concrete walls such as concrete basements and pools. [0003] In view of the above problems, the relevant regulations stipulate that vertical and horizontal construction joints must be set to obtain better construction quality, but there is still a lack of effective measures so that the appearance quality requir...
