KERTO-RIPA SMART PREFABRICATION LARGE FLOOR AND ROOF CAVITIES HOLES & INSTALLATIONS Usually there is a lot of space for piping, running longitudinally within the elements. It is important to include the systems at an early stage in the plans. It is easy to drill holes in the ribs for systems running crosswise. The influence of these holes can be calculated with the Finnwood software. The holes here can be up to a maximum of 70% of the height of the ribs. Usually this is not a problem, but it must always be checked by a structural engineer. The Kerto-Ripa elements are designed with a high level of flexibility. Thus holes can be easily made in floors (and roofs) where required without heavy auxiliary structural elements. Wider or double ribs can be applied where required in order to be able to suspend other elements. These other elements can often be attached onto the main beam using integrated pocket screws or joist hangers. Thereby, for example, a staircase cavity can be achieved easily. Example of an integrated staircase opening, without loose trimmer joists. SPECIAL SUPPORT AND CONNECTION DETAILS Here again clever details come into practice to resolve both building requirements or improve speed on site. Systems can be easily integrated in Kerto-Ripa. Cavities can be made horizontally as well as vertically in all kind of Kerto-Ripa Top panel support increases acoustical performances and simplifies erection. Air tightness and fire safety connection details can be prefabricated too.
