Minimum spacing for channel bolts

PEC standard T-bolts are specifically designed to withstand tension and perpendicular shear loads. These T-bolts provide a secure and reliable connection, even in demanding applications to anchor structural elements such as beams, columns, and walls to cast-in channels in concrete structures, or attaching facade systems, such as curtain walls and cladding, to cast-in channels in concrete structures.

Anchor spacing for standard short cast-in channels

A4-70 cold-rolled channels are the perfect solution for simple applications with static tension and shear loads in two directions. They are the most economical and environment-friendly product. Typical installations include building appliances (e.g. ventilation, heating), stadium seating and ceiling suspension.

PEC cold-rolled cast-in channel SS

The building was designed to achieve BREEAM ‘Outstanding’ rating. The facade was designed to maximise the light coming in. However, due to its design, the loads that the panels need to withstand are significant.

, 1 Bank Street is a steel-framed office tower with a sloping western façade and flexible design based around cellular beams.

Due to its extensive expertise in the design and delivery of glass facade fixings, Construction Fixing Systems were approached to discuss the design. CFS delivered a special design of cast-in channels for the facade, including the design and manufacturing of ski channels.

One Bank Street glass facade project 

Sheldebouw were tasked with designing the building’s glazed envelope. The key challenge in the case of Shard was the building’s irregular shape. As the architect’s vision asked for a highly transparent facade with excellent energy efficiency, Sheldebouw opted for extra-clear low-iron glass. The glazing panels were installed to oversail the steel frames, making them invisible from the outside. Due to new regulations introduced in 2006, the whole facade was designed as a passive double-skin ventilated facade with built-in automatic fiberglass roller blinds.

Similarly, Shard Place, built several years later, has a double-skin glass facade.

In both cases, Sheldebouw needed an experienced partner to design and deliver fixings for the glass facade.

The Shard Quarter, developed in several phases, consists of three buildings: News Building, Shard Place, and Shard itself. Thanks to Sheldebouw, a leader in the curtain wall industry, CFS were involved in the building of Shard and Shard Place.

The Shard, designed by Renzo Piano Building Workshop, was designed as a ‘vertical city’. Shard Place (aka Fielden House) is a residential building built in the third phase of the development.

CFS has extensive experience in designing fixing solutions for glass facades as well as project management to minimise any unexpected delays. Being able to combine their technical expertise and manufacturing capabilities makes them an ideal partner for large complex projects.

In both cases, CFS designed and delivered cast-in channels to fix mullions supporting the glass panels of the facade, including relevant T-bolts.
