DEVICE FOR PLACEMENT OF FIBERS IN FIBERCONCRETE AND METHOD THEREFORE

摘要

The invention relates to the technology of production of monolithic and prefabricated fiberconcrete structural elements working under bending, buckling, shear and other loading conditions, as well as for production of curved elements and in the reconstruction processes. The invention offers to place in the fibroconcrete structural elements a dosed amount of fibers oriented in necessary direction at necessary depth in order to create the internal structure of fibers that in case of incipient cracking begin to work in tension, twisting etc. due to bridging the cracks. During the cracking the fibres are being stretched and pulled-out of concrete. In this case, if fibers of necessary geometrical form are used, it is possible to govern whole opening process of cracks and their propagation.
