Production of hollow core slabs with technological holes

Production of hollow core slabs with technological holes “Oberbeton”

Виробництво пустотних плит з технологічними отворами

Production capabilities of “Oberbeton” allow:

– Change end rectangular cuts on slanted;

– To produce slabs with different cuts (depending on the bearing slab or its connection with other supporting elements);

– To produce slabs with technological holes used for the passage of various communications.

The maximum size of the holes in the slab depends on its length, location, design scheme, shipping and installation, corresponding loads on the slab.

Depending on configuration and location the holes cut through either the fresh concrete (hole’s edge uneven), or frozen. Holes, the parameters of which are beyond the given sizes must always be consistent with the design department of the plant “Oberbeton”.

Permissible parameters of cutting for holes in hollow core slabs

Cut hole is allowed only in certain areas of the vacuum hollow core slabs. The location and size of these zones depends on the type of reinforcement and thickness.

Arrangement of holes with width of more than 800 mm in the floor slabs

If the width of the hole is more than 800 mm, it is recommended to exclude slab at this point. In such a case a slab is based on the neighboring slabs by means of special steel “saddle” brackets. Panel weight is transferred to the neighboring slabs. All design decisions on arrangement of such holes and the use of steel “saddle” bracket should be coordinated with the design department of the plant “Oberbeton”
