SUSPENDED SLABS CONCRETE FLOORS. ECONO Rib and Block is the trademark of our highly economical suspended flooring system. The two-part system, consisting of 'ribs' and 'blocks', forms permanent shutters for the quick and economical construction of floors in multi-story buildings. The 'Ribs' or Lintels: these..
Mar 1, 2008 . by Ted Cushman. In a coastal environment, house foundations need to be water tolerant as well as strong and stable. The classic poured-concrete slab-on-grade a simple monolithic pour with nothing more than a thickened edge at the perimeter is not enough where floodwaters from storm surge or..
Hollowcore ribbed slabs derive their name from the voids or cores which run through the units. . This is a one of the types of concrete slabs. . Fast in construction; No additional formwork or any special construction machinery is required for reinforcing the hollow block..
This form of construction is not very common because of the formwork costs and the low fire rating. A 120-mm-thick slab with a minimum rib thickness of 125 mm for continuous ribs is required to achieve a 2-hour fire rating. Hordy Slab(Hollow Block Slab). Hollow blocks are used to fill portions of the slab thickness; this results..
In-situ concrete slabs are built on the building site using formwork - a type of boxing into which the wet concrete is poured. . In some cases formwork is not necessary - for instance, a ground slab surrounded by brick or block foundation walls, where the walls act as the sides of the tray and..

United Nations Service Building, 3rd Floor. Rajdamnern Nok . principles of good design and good construction in natural hazard prone areas. ... This is a common construction fault with hollow blocks. Columns are inadequate, too small, and poorly constructed, and there should be a reinforced column between the door..
Fire Resistant. Provide thermal and sound insulation: The air in hollow of the block, does not allow outside heat or cold in the house. . In this construction system, structurally, each wall and slab behaves as a shear wall and a diaphragm . Only semi-skilled labour is required for this type of construction. It is a faster and..
suffix of the slab earlier than 28 days. Construction of Monolithic Hollow. Clay Pot Slab\. Hollow (Ribbed) floors are floors eco- nomically designed and constructed using hollow blocks, removable foams or permanent voids former such as clay pots. This type of floors have reduced self weight compared to the solid slabs
Dec 19, 2017 . Eleven one-way simply supported slabs comprised three as reference slabs (solid slabs) and eight as hollow block slabs with two cases of reduction in cross sectional area (23.3% and .. this type of structural floor system, the increasing of the .. As in a pin jointed structure, no bending of the element is
The first category, 'adjacent beams or slabs', included the typical hollow core slabs: prefabricated beams or slabs were put next to each other, and the relatively small joints between them were filled with mortar or reinforced concrete. The second category were 'beam-and-block' systems. This type combined prefabricated..
Precast, prestressed concrete floors offer significant advantages in many types of building construction. . formwork and construction time, and also the precast beam-slab system construction require propping and ..

It was built with Ackermann clay bricks, though one must qualify that these bricks were not only used in the construction of reinforced brick floors, but also for rib and block slabs, a special type of reinforced concrete slab floors (Fig.9).
