Hollow core slabs
Production capacity – 18 lakh sq. ft. per year or 6000 sq. ft. /day.
Prestressed hollow core slabs are the most widely used type of precast flooring. This success is due to the highly efficient design and production methods, choice of unit depth and capacity, smooth underside and structural efficiency.
With VME there is no contradiction between architectural freedom and production efficiency. Our prestressed floor technologies allow you to change product volumes and specifications, and also shift to entirely new products, with ease and efficiency - ensuring faster reaction to new orders and that extra edge over the competition.
Featuring advantages such as longer spans and excellent load bearing capacities, our proven technologies for prestressed hollow-core slabs allow you to build large areas with less need for partition walls, resulting in unprecedented architectural freedom during and after construction.
The Prestressed hollow core units are manufactured using long line extruders. The steel beds are usually 1.2 meters wide and 120 meters long.
The VME manufacturing process deploys dry mix concrete, which means less water is needed compared to conventional processes & thus curing time required is less.
With the production process using modern state-of-art VME machines and experienced crews you can achieve saving of 25 – 30 % in labor hours compared with conventional slab production. You can manufacture 1.5 to 2.5 square meters hollow-core slabs with energy and labor costs you need to produce 1 m2 slabs with equivalent depth in conventional system of construction.
Columns and beams Production capacity – 18,000 running meters per year
Precast beams and columns made in VME Precast factory offers an extremely wide range of technical possibilities. Beams have a rectangular cross-section and are used mostly horizontally for the structure of multi-storey buildings, and also for bridges. Columns have a rectangular section and are used mostly vertically for structures and supports of multi-storey buildings, car parks etc.
Precast beams are mainly used for roof structures, and also for floors with composite action. They are usually in prestressed concrete, although classical reinforced concrete is possible. Beams may be designed composite with the floor to enhance the flexural and shear capacity, fire resistance and stiffness. The main advantage of a composite beam structure is that it permits less structural depth for a given load-bearing capacity. The breadth of the compression flange can be increased to the maximum permitted value, as in monolithic construction. For composite action with hollow core floors, the collaborating section is through the unfilled hollow core. This comprises only the top and bottom flanges of the slab.
Precast columns are manufactured in a variety of sizes, shapes and lengths. The concrete surface is smooth and the edges are chamfered. Columns generally require a minimum cross-sectional dimension of 300 x 300 mm to accommodate the column-beam connections. The 300 mm dimension provides a two-hour fire resistance, making it suitable for a wide range of buildings. Columns with a maximum length of 12 meters can be manufactured and erected in one piece, i.e. without splicing, although a common practice is to work also with single-storey columns.
Wall panels
Production capacity – 18 lakh sqft per year.
Every building material and construction method has its advantages and its disadvantages. A comparison, however, will reveal that no other material or system combines as many benefits as precast wall systems. VME Precast offers a wide variety of Precast panels including internal walls, external wall, boundary walls, sandwich panels etc. Precast concrete made with VME precast factory offers an extremely wide range of visual appearances. Even though the basic structural material is concrete, you can create the impression that the facade has been made of materials such as brickwork, polished marble or granite. And if you wish to maintain the appearance of concrete, you can still create an array of profiles and textures that bring out the natural beauty of the aggregates from which the elements are made.
Load & Non Load Bearing Walls:
Within the VME Group, systems for housing and apartment buildings are normally designed as wall-frame structures. The walls support the vertical loads from the floors and the upper structure. They can also perform only as separating walls. Central stair cases and lift shafts are constructed with precast walls as a variant.
Sandwich Panel for external walls:
Sandwich elements consist of two concrete leaves with an insulation layer in between. The external leaf is generally in architectural concrete. The internal leaf is in gray concrete and may be designed as load-bearing or self-bearing. Load-bearing means that it is supporting the floors and the structure above. Self-bearing means that it is only supporting the self-weight of the facade.
The U- value of such insulated walls are as under:
