The Basics on Cast in Channel System

Various cast in channel systems are available, ranging from simple self-anchoring slots for receiving restraints to channels with integral anchors. Concrete fixes can be screwed to them without drilling through the concrete, providing the necessary adjustment. Infills prevent concrete from ingressing into channels and nail holes aid in fixing channels to timber formwork. We will be discussing the installation and casting process in this blog post. 

Prepare with Cast in Channel System 

Cast System inserts can be used with or without baseplates, for instance lifting inserts for transporting precast parts, anchor channels, embedded plates with headed studs, bent rebars connected to internally threaded rods, and custom components for attaching masonry and heavy facade panels to walls. 
In situations where the external load's location is known and the reinforced concrete member's reinforcement is appropriately positioned, cast-in-place anchor fastening systems provide the greatest advantage as a result of detailed planning during the conceptual stage. In contrast to the two other systems, cast-in-place requires no further work to be done after the concrete has been poured, which minimizes damage to the concrete base and embedded reinforcement as well as delaying site productivity, which is crucial for both post-tensioned and high-strength concrete members. Despite these challenges, the implementation of these systems requires extra planning during their conceptualization, and there is a potential of erroneous placement during execution, which can be avoided if proper training is provided at the site.  

Cast-In Anchor Channels – Flexibility like no other 

An anchor channel is either a cold-formed, a hot-rolled, or a temperature-controlled and -rolled channel with an integrated round-headed rigid anchor. These anchor channels are tied to reinforcing prior to casting concrete. For concrete protection, a low-density polyethylene foam is installed in the channel, which is then removed after curing. Various components can be installed into the channel itself using special T-headed bolts. 
Cast-in channels allow unprecedented flexibility on a grand scale. Not only can the fixture be positioned with the T-bolts attached, but the cast-in channel can also be positioned very close to the edge of concrete members. Post-installed anchors are less capable of carrying loads since their distance from the edge allows them to handle lower loads than pre-installed anchors. As well as eliminating drilling, flexibility here implies reducing the installation time of facades and lifts, giving architects and façade consultants greater flexibility in planning layout and elevations, adjusting fixing positions, and anticipating load transmission. As a consequence, this: improves overall project efficiency; allows higher loads to be carried; and uses ETA-approved and well-designed system solutions that can even be used in pre-tensioned slabs. 

Cast-in anchor bolt:  Selection and creation criteria 

Besides the standard channel range, customers can also request bespoke design and cast-in   channel installations for those areas not suitable for standard types. When there are specific restrictions, such as complex corner applications, low slab thicknesses, narrow edge spaces, or higher design loads, special cast-in channels are the preferred option. We offer anchor bolts and Lock Nuts that will allow you to connect to the channels in a secure and easy manner. A wide range of construction works can be conducted using this system. When selecting an anchor channel, consideration must be given to three factors - the correct channel size, the anchor T-bolt, and the T-bolt's strength. According to the limit-state approach, the characteristics of the channel, concrete, and reinforcement are reduced, while the tension and shear loads are increased.  
Our engineers and architects can be confident that their structure will have the highest level of safety no matter the location or the loading conditions, as we offer full guidance in selecting and designing the right cast in channel system. The purpose of this blog is to help you understand the process and application of cast in systems. Select the best quality from us.
