Hollow Core Precast Concrete Floor Panels Slab Thickness

Maximize space in any house plan for approximately 20 per square foot with hollowcore roof and floor systems from county materials.

Hollow core precast concrete floor panels slab thickness. Spancrete hollowcore precast concrete planks slabs are fire resistant reduce weight and costs. Milbank hollowcore floors also known as slabs or planks are pre stressed concrete slabs with internal tubular voids creating an efficient and lightweight plank that is far lighter than other floor slabs of equal thickness or strength. The uk s leading manufacturer of pre stressed hollowcore concrete floors. The precast concrete slab has tubular voids extending the full length of the slab typically with a diameter equal to the 2 3 3 4 the thickness of the slab.

We also do cut slabs in custom sizes according to each individual installation. Our precast hollowcore floors are available in sections 150 200 250 and 260mm deep. Hollowcore systems are prestressed concrete plank that serve as both a ready made sub floor for a garage and a ceiling for additional living areas. Two things need to be addressed.

Prestressed hollowcore floor panels available in 150 200 250mm depths. The use of precast concrete hollowcore flooring is a highly cost effective solution that fits easily into any structural system such as steel or concrete frame or indeed masonry construction. The cables are drawn to a design tens. Figure 1 7 shows typical precast lattice slab floor units.

We core drill hollow core precast slabs when needed. The units themselves are manufactured at a width of 1200mm and depths of 150 200 250 and 300mm. Along with being significantly easier to lift and handle during the construction process hollowcore slabs lower construction costs related to the amount of material required to cast the slabs as well as the cost to transport the finished product to the job site. Our precast hollowcore slabs are significantly lighter when compared to solid precast concrete floor slabs.

See span load tables for full details. This makes the slab much lighter than a massive solid concrete floor slab of equal thickness or strength. These slabs are supported by cables embedded in the webs of the slabs under tension hence the name prestressed concrete. All slabs are 1200mm wide and can be supplied with a maximum length of 12m depending on design and application.

Precast lattice slab floor units are typically 50 to 100 mm thick reinforced with steel bars forming a lattice girder that is only partially embedded in the precast unit.
