Hollowcore Plank Construction Details

hollowcore plank construction details

When it comes to construction projects, every detail matters. At Floorspan Contracts, we specialise in providing high-quality hollowcore concrete planks suitable for a variety of building applications. In this guide, we’ll delve into the essential hollowcore plank construction details and how they contribute to structural integrity and performance.

HOLLOWCORE PLANK BEARING REQUIREMENTS

Whether your project involves masonry or steel frame buildings, it’s crucial to adhere to specific bearing requirements for hollowcore planks:

Masonry Walls: The minimum bearing requirement onto masonry walls is 100mm.

Steelwork: Planks require a minimum bearing of 75mm onto steelwork.

These bearing requirements ensure proper support and stability for the structure.

TYPICAL BEARING CONFIGURATIONS

 

 

 

 

 

One common application involves hollowcore slabs bearing onto a 100mm wide masonry wall. At Floorspan Contracts, we can customise floor layouts to accommodate service voids, cut-outs, and notching according to the building envelope.

For projects requiring large openings, bespoke steel trimmers can be provided to trim out the opening while maintaining structural integrity. These details are clearly marked on the design drawings we provide, ensuring seamless integration into the construction process.

bearing on shared walls

 

 

 

 

 

In situations where slabs need to share a wall, special measures may be required, especially if the wall is narrower than standard. Our experienced designers can assist in accommodating a 140mm wide bearing wall with tailored solutions.

Side bearing onto blockwork walls necessitates filling the gap between the plank underside and the wall top with mortar. This not only enhances air tightness but also reduces sound transmission, contributing to a more comfortable indoor environment.

bearing on shelf angles and steel

 

 

 

 

 

 

When bearing onto steel supports or shelf angles, careful consideration is given to ensure optimal performance. Chamfered plank ends aid installation, and filling voids with concrete by the main contractor creates a solid floor, enhancing sound separation and fire safety.
