Description

Climbing external formwork support platform

technical field

The utility model relates to the technical field of concrete wall construction, in particular to a climbing formwork support platform.

Background technique

Compared with other formwork construction technologies, climbing form construction has the same advantages as sliding form construction: it is not affected by site stacking conditions, has good structural integrity, and can be arbitrarily raised with the height of the structure. Although the construction speed of the climbing formwork is not faster than that of the sliding formwork (since the sliding formwork can be climbed during the initial setting stage of the concrete, while the climbing formwork construction must be completed when the concrete strength of the next layer reaches 10Mpa or higher, the climbing construction of the previous layer can be carried out.) But its The construction speed can basically reach 3~5 days per floor. Relatively speaking, climbing formwork construction has more prominent advantages: quality is easier to control, structural errors are small, deviation correction is simple, and construction errors can be eliminated layer by layer; at the same time, the construction process can be interrupted, and temporary protection and operation can be carried out against severe weather conditions.
