Welcome to the Reinforced EPS Structural Panels Installation, the innovative world of Expanded Polystyrene (EPS) core panel systems, where modernity meets efficiency, safety, and affordability in building construction. These panels represent a cutting-edge solution for constructing durable and versatile buildings, serving as both load-bearing and non-load-bearing elements.
At the heart of the EPS core panel is its 3D design, consisting of a welded wire space frame with a polystyrene insulation core. This unique configuration provides exceptional strength and thermal insulation properties, ensuring structural integrity and energy efficiency.
During installation, the EPS panels are positioned and encased in shotcrete on both sides. This process enhances the panels’ durability and load-bearing capacity, making them suitable for a wide range of construction applications.
Manufactured with welded reinforcing meshes of high-strength wire and diagonal wire, along with self-extinguishing expanded polystyrene, EPS panels are engineered for reliability and longevity. The combination of factory-made components and on-site shotcrete application further enhances the structural integrity of the building.
The EPS core panel system offers a modern, efficient, and cost-effective solution for building construction. With its innovative design and construction process, EPS panels provide a durable and sustainable building solution for both residential and commercial projects.
EPS panel after shotcrete has the following five components (as Fig.):
i. The outer layer of shotcrete.
ii. Welded reinforcing mesh of high wire.
iii. The core of expanded polystyrene sheet.
iv. Diagonal wire (stainless or galvanized wire).
v. The inner layer of shotcrete.
The welded mesh fabric connected piercing polystyrene with truss of steel wire, welded to the welded fabric at an angle. It gives rigidity spatial structure,and simultaneously prevents polystyrene core shifting.
Individually welded internal strut wires or diagonals extend through the panel core between each surface. These galvanized strut wires are welded continuously in the required spacing so they form, with the welded wire fabric, into a triangulated truss system which greatly increases the panel strength. EPS panel is a versatile structural element designed for floors, walls, partitions, roof and stairs. Pic’s shows the welded reinforcing mesh of the EPS panels at different cross-sections. The typical EPS panel is generally manufactured with dimensions of 1200 m width, 3000 mm length and over all thickness range of 80-230 mm. The panels are finished at the site using minimum 30 mm thick shotcreting of cement & coarse sand in the ratio of 1:4 applied under pressure. The shotcreting coat encases the EPS Core with centrally placed steel welded wire mesh.
Some of the advantages of the EPS Core panel systems are as follows:
i. Reduce the cost of construction
ii. Reduce Construction period
iii. Reduce transport cost. Light weight panels: do not requires cranes and other heavy construction equipment. (A Standard panel of size (1.2×3) m without shotcrete weighs 20 kg).
iv. The installation does not need heavy construction equipment.
v. Ensure high levels of thermal insulation, sound insulation, as well as sanitary and fire safety.
vi. EPS 3-D panels allow no additional cost to erect buildings in areas with moving soil, especially heaving, subsidence, frozen ground, and remote areas.
vii. Strength and durability – used extruded polystyrene virtually inert and does not absorb moisture, is durable and resistant to decay.
Some of the Limitations of the EPS Core Panel System:
i. EPS Panel construction system may only be used in the construction of foundation walls supporting 4 storeys or less, unless designed by a professional engineer.
ii. Concrete must be applied by either the “shotcrete dry” or “shotcrete wet” process in accordance with ACI 506 R-85, “Guide to Shotcrete,” by the American Concrete Institute.
iii. Compressive strength of concrete shall not be less than 20 MPa.
iv. The steel reinforcement shall have a minimum allowable stress (fy) of 415 MPa.
The EPS Core panel system is eco-friendly and visually appealing, offering both environmental benefits and aesthetic charm. Its rapid construction process leads to significant savings in both time and costs. This technology has been successfully implemented in numerous African and European countries, involving various agencies and demonstrating its widespread effectiveness.
