Specific Features

1. Customers can lower construction costs and lighten the weight of Hollow Core because the planks are hollow. Thus, customers can save concrete and other structures including piles, foundations, columns and
2. Hollow core is quick to install as it does not require temporary bracing for the construction. Hence, it is convenient to work and saves time and labor as well.
3. The bottom surface of the Hollow Core is smooth so no plaster or installation of ceiling is required.
4. Hollow Core has a Long span making the cross-section highly efficient and lightweight compared to other cross-sections; However, there is no reduction of the cross-sectional power and durability which allows the Hollow core use with different lengths of span up to 8 meters without deflection problems (according to the thickness of Hollow Core)
5. All of the Hollow Core slabs are standard with the high efficiency manufacturing processes, extruded and pressed concrete; therefore, the slabs have a consistent shape.
6. Hollow Core is strong because it is made from dry concrete (NO SLUMP CONCRETE) and is passed through the modern machinery manufacturing processes Thus, the Hollow Core is higher compressive strength and quality than the general Planks.
7. Because of the Hollow Core, when laying the Hollow Core, there will be a Shear Key groove for grooving with sand mortar making it possible to distribute the load between the Hollow Core slabs
8. Due to the air inside the hollow of the Hollow Core, it could greatly reduce the transmission of sound and temperature.
9. Because the concrete coated with steel is sufficiently thick, Hollow Core is able to withstand the heat temperature for hours. In the case of the fire that is severe at any point, it will cause only local... Read More

10. Hollow Core, with a large hollow, is used for an electrical wiring, a hole for ventilation and water pipes. In addition, the structure of a thin upper and lower surface allows for quick and easy modifying, drilling and opening solid concrete litter channels.

The on-site preparation and the preparation of Hollow Core support beams

1. Casting of building columns
2. Preparing the stock place
3. Preparing the Hollow Core support beam
4. Beams that cover the sides of Hollow Core
5. The process of laying Hollow Core
6. The furrow done by a builder
7. Laying the steel grating
8. Pouring the topcoat concrete

  How to install Hollow Core

1. A sling is used to wrap the Hollow Core floor from the end of the sheet 25-30 cm.,by considering the safety
2. Dcon Hollow Core is placed on the structural beam for not less than 7.5 cm per side. If the beam distance is less than the requirement, customers must consult a project engineer before the installation. The beam where the Hollow core that is placed must be smooth before the Hollow Core plate is arranged.
3. Customers should check the installation quality according to Shop Drawing.
4. Dcon Hollow Core sheets must be rest on the installed plates and should not be stacked for more than 1 layer.
5. After finishing the installation of Hollow Core, Mortar must be applied along the Shear Key line. Then the steel grating is placed and the Topcoat concrete is poured ,making the Hollow Core to distribute the force well.
6. Pouring Topcoat concrete must be poured from the edge to the middle of Hollow Core plate and should not be poured at the specific position especially the middle of the plate because the weight of the Topcoat might exceed the capacity of the weight support of the Hollow Core slab.
7. A sling is used to wrap the Hollow Core floor from the end of the sheet 25-30 cm.by considering the safety first.
