Five load types for concrete industrial floors

Depending on the location of use, different types of load are used for a concrete industrial floor. According to these requirements, the structure, the reinforcement, the plate thickness and the course of the joints must be adapted. In addition to the static requirements, service properties such as abrasion and skid resistance must also be taken into account.

Five types of stress

A load in any case consists of a traffic load that is either dynamic in nature or acts as a static load. Dynamic traffic is generated by walking and driving. Static load is created by installations such as high rack systems, partitions and machines.

Changing or constant temperature loads often form another focus. Particularly effective in concrete shrinking forces that bring movement in the ground and which must be counteracted by appropriate building precautions.

Mechanical forces caused by rolling or sanding on the surface as well as frost must also compensate for and tolerate industrial floors made of concrete as well as, if necessary, the action of chemical substances such as acids, lyes, fats, sulfates and salt.

Physical and mechanical forces

Traffic loads and mechanical loads determine the construction and dimensioning of concrete industrial floors. The expected load values ​​must be used as a basis. Maximum point loads must be able to withstand industrial floors over the entire area. Their durability and resilience can be enhanced by embedded reinforcement without having to increase the overall thickness.

When using industrial floor panels, the individual panels are reinforced. The larger the individual panel sections, the larger the gaps between the joints. In order to compensate for the shrinkage forces acting on the distances, combinations of "hard" reinforcements such as steel mesh or steel fibers with "soft" reinforcements made of spiral shapes are used. As a further element, the structure of the industrial screed is designed for the physical forces.

Chemical resistance

A mixed form represents stresses due to mechanical force, which are taken into account both in the physical structure and in the industrial floor coating. Abrasion and durability depend on both the statically appropriate subsurface structure and the covering wear layer.

While industrial floors with PVC coating or a gelcoat are suitable for almost all mechanical loads, sometimes a combined coating and underbody model must be installed when exposed to chemical substances.

Tips & Tricks

For industrial floors, there are legally binding European and German standards. Have each design approved by the appropriate building authorities.
