A Formwork Structure of Fair-faced Concrete Group Columns with Small Diameter and Large Slender Ratio

Abstract

The invention discloses a clean water concrete pile column template structure with small diameter and large slenderness ratio. The template structure comprises a template supporting frame, a bottom limiting component, an abutment reinforcing mechanism and at least two up-down abutted PVC column templates, wherein the template supporting frame is a rectangular parallelepiped frame composed of vertical upright poles, longitudinal horizontal rods and lateral horizontal rods; the bottom limiting component comprises a limiting base and at least three limiting piles; the abutment reinforcing mechanism comprises four limiting plates, two opposite pulling screws, four U-shaped clamping seats, four fixing nuts and four supports. The template structure can realize rapid construction of clean water concrete columns, and has good application prospect; and the outer surfaces of the constructed columns are smooth and have no convex marks.

Description

technical field [0001] The invention relates to a column formwork construction structure, in particular to a small-diameter and large-slender-ratio fair-faced concrete group column formwork structure. Background technique [0002] With the continuous innovation of architectural technology, on the premise of satisfying its function, the architectural design method with novel shape and outstanding features is more and more favored by architects. In the field of fair-faced concrete, a clear-faced concrete column with a small diameter and a large slenderness ratio has gradually been applied to building structures. This kind of clear-water column usually has the characteristics of small diameter, high height, large quantity, and strict requirements. [0003] Existing formwork technology usually adopts custom-made steel formwork or custom-made wooden formwork for the construction of fair-faced concrete columns. The steel formwork is heavy and expensive, and it is not suitable for ...

[0003] Existing formwork technology usually adopts custom-made steel formwork or custom-made wooden formwork for the construction of fair-faced concrete columns. The steel formwork is heavy and expensive, and it is not suitable for large-scale construction

The wooden formwork is composed of left and right pieces connected by concave-convex card slots. However, after the formwork is removed, a flickering vertical trace will usually be formed at the slots of the wooden formwork and the joints of the segmented wooden forms, resulting in poor quality of the surface of the fair-faced concrete.
