Often asked: What is a whaler in construction?

What is construction Waler?

waler (plural walers ) (structural engineering) A plank of wood, block of concrete, etc., used for support or to maintain required separation between components in order to help maintain the form of a construction under stress.

What is the function of a Waler?

Walers perform two other functions. First, they protect the concrete floating dock from impact from a docking boat. Secondly, they present a gentle surface to the hull of a boat using the moorage, especially when the walers are built of structural timbers and when combined with protective rub rails.

What is a concrete Waler?

Brackets attach directly to the concrete forms to straighten the wall and minimize the need for additional bracing. In most residential construction, one row of walers at the top of the wall is usually sufficient.

What is a Waler in formwork?

[′wā·lər] (civil engineering) A horizontal reinforcement utilized to keep newly poured concrete forms from bulging outward. Also spelled whaler.

What is a raker in construction?

In this method, inclined members called rakers are used to give temporary lateral support to an unsafe wall. One or more timbers slope between the face of the structure to be supported and the ground. The most effective support is given if the raker meets the wall at an angle of 60 to 70 degrees.

What is difference between formwork and shuttering?

Formwork is the overarching term that’s used to describe the forming process. Shuttering is defined as the temporary moulds that are used to hold the wet concrete in place until the concrete has set and cured. Projects of different sizes will often need to use both formwork and shuttering methods.

A waler is a horizontal beam that is attached with bolts to a larger upright structure. The structures that you may see with walers on them are often retaining walls and docks. Walers ‘ overall purpose is to support the structure they are attached to.

What are Form ties?

Form ties (sometimes referred to as tie bolts) connect opposite faces of wall formwork to restrain the applied concrete pressures. They transmit loads in tension between stiff vertical and/or horizontal members associated with the main formwork.

How is formwork calculated?

The formwork is measured in terms of area that is in contact with the concrete surface. For example, the formwork for concrete footing will be calculated as the surface area of four sides of foundation only. Bottom of the footing is resting on earth, there is no need of any formwork and top of footing is open.

How do you calculate concrete pressure on formwork?

Calculating Concrete Pressures Sq. Ft. per tie x 150# x height of pour = pressure per tie. example: 2’x2′ tie pattern equal 4 sq. ft. per ties. 4sq. ft. x 150 x 6′ height of pour equals 3600#. This is the pressure of the bottom tie of a 6′ lift of concrete with the ties on 2’x2′ tie pattern.
