Girder Floor Truss

These are often pre fabricated and sent to a construction site.

Girder floor truss.

Girder trusses have a long straight design. This girder is made of similar trusses built and fastened together to act as one unit to support the load. Span tables below illustrate common combinations of the multiple variables available. Forming the top of the floor truss.

Repairs are costly and time consuming. A girder truss is designed to support other secondary roof supports. Top chord bearinga floor truss support condition in which the truss load is transferred to the bearing or support through the top chord and 4x4 block end detail. Floor trusses are not fire code friendly.

The top chord is always in compression and the bottom chord is always in tension. Floor truss span chart each individual floor truss design is unique based on multiple variables. Girders are trusses specially designed to carry extra loads from framing and equip ment. To strengthen a truss the fabricator may double its top and bottom chords make side by side girder trusses use larger truss plates or stronger wood or use some combination of these techniques.

The wide nailing surface provides for easy gluing and quick accurate attachment of sheathing reducing squeaks and improving floor performance for the life of the structure. Required for girder floor trusses slope for drainage as required cantilever span controlled by lumber size grade and deflection limitations floor cantilevered perpendicular to floor truss span section aa floor truss jacks floor joist scab cantilever floor cantilevered perpendicular and parallel to floor truss span strongback lateral supports. Floor trusses are built with 2x4s or 2x3s with a wide stable bearing surface that is easier to work on and around. A truss is a roof or floor support structure built from a connected series of box or triangle shaped elements to distribute load to a building s walls or foundation.
