HAND-E-FORM® for Curved or Circular Walls

HAND-E-FORM Curved Walls

  • HAND-E-FORM Flex Panel

    Flex Form Panel

    Flex Form Panel is set between the panels and the clamp. A vertical row of spreader ties is required on both sides of the flexible form panels.

  • HAND-E-FORM Face Sheet

    All-Steel Face Sheet

    The lightweight all-steel face sheet extends to the edge of the panel, giving you consistent concrete texture from one joint to another. This face sheet will produce steel-smooth concrete year after year. With proper care, you will never have to replace the face sheet of an EFCO steel form.

  • HAND-E-FORM Tie Bearings

    Tie Bearings

    The tie bearing in a HAND-E-FORM® panel is an integral part of the panel. It is designed to transfer the concrete load from the tie into the flanges and grill work of the panel. It is conveniently located to permit easy placement and removal of the Spreader Tie Pins. The locking device on the pin bearing is designed to lock the pin into position to hold it securely during the pouring operation.

  • HAND-E-FORM Flange Holes

    Holes in Flanges

    Holes in flange are placed every 1 inch to permit the panels to be clamped together in numerous staggered positions. All EFCO HAND-E-FORM® panels have holes in the flanges at 1" center-to-center around the perimeters for use by the various clamps and other accessories.

Handset Radius Formwork

Round tanks and curved walls are an excellent application for EFCO’s HAND-E-FORM® system. Standard HAND-E-FORM panels used with HAND-E-FORM flexible panels will form the required radius. The size of the standard panel will vary according to the radius and amount of chord allowed.

Easy-to-Use Forming System

The HAND-E-FORM® Forming System is easy to use and the most versatile handset forming system on the market. Inexperienced workers quickly learn the simple mechanics of this system. Unlike competitive systems, HAND-E-FORM panels are lightweight and conveniently sized, so even the largest panel can be set and stripped by just one worker.

FEATURES AND BENEFITS

  • Set and stripped with one worker
  • Versatile handset forming system
  • Easy to use
  • No wood walers required
  • Reduced number of ties with greater tie spacing
  • Single joint finish

The first step to form a round tank is planning your work. An engineer can calculate the inside and outside circumference of tank walls. Next, select the standard panel module for the tank depending on the allowable chord dimension. Most tanks are formed with a 24″ chord but sometimes a smaller tank requires a 16″ or 12″ panel. Some very large tanks may use a 48″ chord.

A normal assumption is that a 2″ flexible panel will be used between each 24″ modular panel on the inside of the wall. Completing the outside plating plan requires using wider flex panels in order to make up the difference in the circumference of the inside and outside of the tank.  

All-steel EFCO HAND-E-FORMS cannot be matched for durability. With proper care, the steel face sheet of a HAND-E-FORM panel will last a lifetime. HAND-E-FORM face sheets are five times more dent resistant than composite sheets and can withstand the demands of being used over and over again on your jobsite. Add it all up—maximum durability, less labor to clean and maintain, plus the best in quality concrete finish equals the benefits of steel.

The HAND-E-FORM® Forming System is an easy-to-use system. It is the most versatile handset forming system on the market today. Inexperienced workers quickly learn the simple mechanics of this system. Unlike competitive systems, HAND-E-FORM panels are lightweight and conveniently sized. Even the largest panel can be set and stripped by just one worker.

The duration of time between placing concrete and removing/stripping formwork and shoring depends on a variety of factors, but it is ultimately based on age criteria and the minimum concrete strength determined by the project engineer/architect (reference ACI 347-R14; 5.7.1).
