Concrete industrial floors, also called high-performance floors or high-resistance floors, are elements intended to resist loading efforts and transmit them to the subgrade. They are indicated for places where products are stored vertically, generating punctual or distributed efforts with large loads, as well as for places where there is heavy vehicle traffic or loaded forklifts. Comaro Engenharia's industrial floor is widely used in places such as industries, logistics warehouses, distribution centers, supermarkets and wholesalers, shopping malls, maneuvering yards, among others.
Prestressed concrete industrial floors are structures that use reinforcements with strands anchored at the ends and pulled through the use of a hydraulic jack, in order to generate loads that compress the concrete plates horizontally. This load generated has the function of guaranteeing the neutralization of the effects originated by the external forces that are on the structure, in order to balance the forces and effects and thus achieving a drastic reduction of cracking and deformation in the structure.
The reinforced concrete floor is ideal for areas with large loads and many interferences. The use of reinforcements composed of welded screens, on industrial floors, aims at structural reinforcement and/or combating concrete shrinkage cracks, and is characterized as a solution in the application on industrial floors due to its practicality and speed in the process. Steel meshes are a type of prefabricated reinforcement composed of a network of rectangular meshes formed by overlapping steel wires longitudinally and transversely, with all its points of contact welded by the welding process.
The growth of civil engineering provided the introduction of several new materials, and steel fiber reinforced concrete is one of the main examples. These fibers have the function of keeping closed the cracks that will eventually appear in the concrete, and are used to partially or totally replace the reinforcements in concrete floors.
Compared to reinforced concrete floors with welded mesh, floors reinforced with steel fibers promote greater agility in the process of preparing the area to be concreted, in addition to considerably reducing the generation of steel waste on site.
The flooring reinforced with Macrofibers, also called concrete flooring reinforced with synthetic fibers, is an extremely used solution in the market, and Comaro Engenharia has a wide experience in this solution. Macrofibers have characteristics similar to those of metallic fibers, and the concrete floor reinforced with this type of fiber represents an alternative to welded mesh floors or floors reinforced with metallic fibers. Its main function is to improve the properties of concrete and mortar by providing homogeneous reinforcement that controls shrinkage cracking. The result is a concrete that is more resistant to impacts and with excellent mechanical properties.
