PARTS OF A SUSPENDED TIMBER FLOOR The suspended timber floor involves the over site concrete slab, honey combed sleeper walls, wall plates and floor joints. The diagram of figure two shows the linkages between the various components of the floor. The examination of the illustration can help you to identify the functions of the various parts. FUNCTIONS OF THE PARTS OF SUSPENDED TIMBER FLOOR -- Sleeper walls serve as the main support to the load of the whole timber floor system. -- Floor joist serves as the barrier of the floor boards. It is to the joists that the floor boards are nailed. -- Wall plate functions as the main timber link between the timber floor system and the sleeper wall. -- Floor boards serve as the floor surface for the room. PRECEDURES                                                                                     The use of the following procedures for suspended timber floor construction is important. -- Ensure that the concrete floor is of high strength to receive the load of the timber floor system. -- Erect the sleeper walls at the appropriate layout and ensure that it is honey combed to provide adequate ventilation. -- Apply the damp proof course at the appropriate level. -- Place the wall plates correctly on the D.P.C. -- Place the floor joists at the set intervals across the wall plate. -- Finally, place the floor boards across the joist and nail accordingly.
