Field of the invention

The invention relates to a method for providing a movement joint in a concrete floor supported by a sub-base as defined in the preamble of independent claim 1.

The invention also relates to a movement floor joint apparatus for providing a movement joint in a concrete floor supported by a sub-base as defined in the preamble of independent claim 13.

Movement floor joint apparatuses are mainly used in connection with large concrete floors supported by a sub-base such as by a sand bed. Large concrete floors are structures formed of concrete slabs and cast directly in place for example upon a sub-base such as upon a sand bed on the construction site. Usually it is necessary to cover relatively large areas by means of concrete. Due to the shrinkage and thermal movements of concrete, large areas must be divided into smaller parts i.e. into concrete slabs with movement floor joint apparatuses. A movement floor joint apparatus must allow adjacent concrete slabs of the concrete floor to move horizontally relative to each other due to shrinkage and thermal movements. These movements mean here movements that are in the direction of the joint and perpendicular to the joint. In contrast, vertical movements perpendicular to the slab plane must be prevented, in other words the joint must be capable of transferring vertical load between the concrete slabs of a concrete floor.
