Fixing to Steel RHS Sections (Masonry Supports)

 

#

rhs1

Various solutions are available for fixing Wincro Support Systems to rolled hollow section (RHS) steelwork structures.

 

All systems are carefully designed by our Technical Design Team to suit the specific application and our optimisation design package ensures the most cost-effective system is designed quickly and safely. Systems are designed to suit the masonry height to be supported, the cavity width and structural fixing position.

 

The support systems featured in this section can be fixed directly onto RHS frame structures by the use of the Wincro RHS Blindbolts, or suitably coated T Head bolts into channels pre-welded to the RHS frame. To avoid the effects of bi-metallic corrosion, all Wincro support systems are supplied complete with isolation patches and neoprene washers where required.

All systems utilise an angle support and come complete with vertical adjustment of up to +/- 26mm. Welded channels onto the RHS frame provide virtually unlimited horizontal adjustment. Wincro recommend RHS sections are site drilled when using the RHS Blindbolt to facilitate any horizontal adjustment that may be necessary.

 

WSC Bracket System

 

Wincro WSC Bracket System comprises of a continuous thin angle support complete with welded brackets incorporating a serrated slot and adjustment washer. Capable of supporting masonry over 9m in height and designed to suit cavities greater than 40mm, Wincro WSC systems are ideal for fixing straight on to steel framed structures.

Adjustment

 

The Wincro Serrated Slot and Washer allows for vertical adjustment of +/- 26mm and using welded channels onto the RHS frame provide virtually unlimited horizontal adjustment. Lateral adjustment is provided by the use of stainless steel packing shims between the system and structure.

 

For non-standard situations, please contact our Technical Design Team for further advice.

 

Bi-metallic Corrosion

 

Careful consideration should also be taken to avoid the effects of bi-metallic corrosion where the two dissimilar metals meet. Wincro recommend the use of Isolation Patches or the painting of the contact area between the metals to prevent such an occurrence.

 

Design

 

Detailed general arrangement (layout) drawings are provided with our masonry support designs, fully referencing systems, fixings and installation details prior to manufacture.

 

Systems can be adapted to suit special masonry details including the support of soffit brickwork or atypical coursing positions. An example of configurations are shown below. Angles can also be supplied curved on plan to suit radiused masonry.

 

WSCFA Cold Formed Angle / Gusseted Angle System

 

Wincro WSCFA Cold Formed Angle Support Systems are generally used where there is a reduced cavity situation or a need for the cavity to be closed at the support location.

Comprising of a traditional support angle, WSCFA systems are capable of supporting masonry over 9m in height and can be designed to incorporate all the fixing methods employed for other masonry support systems shown in this section.

 

Where larger cavities are encountered, WSC Bracket Support Systems tend to be more cost-effective.

 

WSCFA Angles are normally supplied in lengths up to 3 metres and can be supplied with either serrated vertical slots or welded serrated patches where vertical adjustment needs to be designed into the system.

WSCFA Angle System can also be supplied Inverted to accommodate situations where the coursing level/horizontal movement joint is above the fixing position.

An example of WSC and WSCFA configurations are shown below.
