In the case of long span truss work, bearing lengths of at least 3" are quite common. Trusses span greater distances than framed floor assemblies and can be designed to span the entire building, eliminating center load bearing supports. They are moderately more expensive than framed floor assemblies, but provide a remarkably strong floor with little deflection or "bounce" to it. Another advantage to this type of structural system, is that utility installations can be run between the webwork components. Never allow trades to cut or drill into the members of a truss, for they are manufactured precisely for the loading conditions they will undergo during the life of the building.
Many people also have questions about the tiles durability and use. Interlocking floor tiles are usually placed on the floor underneath it, meaning there is no adhesive or floor base. Some may become concerned that the interlocking tiles will become loose easily due to the lack of adhesive. This is not the case. Tile floor systems are designed to lock together permanently. When appropriately installed, the interlocking floor tile should remain exactly as it was placed until the user decides to move it. Interlocking tile floors are appropriate for any use, from industrial to residential. This interlocking flooring system does not have as much risks compared to traditional tile flooring.
All joists must extend at least 1-1/2" on to a bearing assembly, of either a beam or full height wall, unless metal hangers are installed to provide proper bearing support against other structural components. Beams, which support the floor joists over greater spans, are constructed in the form of laminated joists often referred to as built up beams, or one piece solid load bearing beams, cut from logs or manufactured. Electricians and plumber may often cut or drill into the joist work to install utilities, and this is accepted, so long as they do not remove more material than what is required by codes. This type of floor system is usually the cheapest to install.
