Circular Column Formwork

Applications Features / benefits Product list
 

Circo round & tall

Circular columns are a prominent architectural feature in structural and civil engineering projects. Since concrete cosmetics are rarely admitted, the demands on the concrete finish (fairfaced concrete) of circular columns are high. Circo is a leading formwork system – totally made of steel – for diameters from 25 to 80 cm and delivers a perfect fairfaced concrete finish in

  • car parks
  • skeleton construction
  • halls
  • bridge piers
  • commercial projects
  • hospitals

Circo can also be combined with Mammut wall formwork to shape circular stop-ends.

Circo circular column formwork

Circo circular column formworkZoom
steel construction with steel sheeting, state-of-the-art surface coating. Consists of two semi-circular halves, inside sealed with clear varnish. Accurate height extension owing to special connecting flanges. Can be combined with Mammut-panels (e.g. for stop ends), up to Ø 60 cm with Mammut assembly locks, for Ø 65 cm and more with transition locks Circo-Mammut. Standard height 300 cm, extension heights 100 cm and 50cm.

M-assembly lock

M-assembly lockZoom
galvanized, to tightly connect and align Circo-panels. Clamping length 12 cm. Four (4) M-assembly locks are required per meter in height.

Transition lock Circo-Mammut for Ø 65 cm and more

Transition lock Circo-Mammut for Ø 65 cm and moreZoom
galvanized, to connect Mammut-panels to Circo-panels with a diameter of more than 65 cm to form semi-sircular stop ends.

Brace frame 250

Brace frame 250Zoom
galvanized,to align and brace the formwork, without formwork-prop connector, it consists of a push-pull prop R 250 (190-320 cm), a brace SRL 120 (90-150 cm) and a double-jointed footplate. It is attached to the Circo-panels with head bolts 16/90 and cotter pins 4 (come with Circo-panels).

Circo-platform

Circo-platformZoom
access platform with foldable guard-railing, galvanized steel frame covered with non-slipping aluminium. Load capacity 2 kN/m². It is attached to the Circo-panels (half shell) by using two (2) Circo-scaffolding brackets. Material required for a complete platform: 1 Circo-platform, 2 Circo-scaffolding brackets, 4 flange screws, 2 Circo-railings.

Circo-scaffolding bracket

Circo-scaffolding bracketZoom
galvanized, is attached to the Circo circular column formwork with two (2) flange screws and with an integrated hammerhead screw. The flange screws have to be ordered separately. Two (2) Circo-scaffolding brackets are required per platform.

Circo-railing

Circo-railing
galvanized, is attached with two (2) integrated bolts to the guard-railing of the Circo-platform. Two (2) railings are required per platform (not shown).

Flange screw

Flange screwZoom
galvanized, with Dywidag thread Ø 15 mm. To attach Circo-brackets to half-circular Circo-panels. Length of thread 18 cm.
