Simply enter the required span to see a range of results that will work.
Easi joist flat roof span tables.
Span tables for solid timber joists.
Ceiling joist span use this table to determine the maximum lengths of ceiling joists based on species of lumber joist spacing and joist size.
Notches are not to exceed 0 125 of the depth of the joist and are to be located between 0 07 and 0 25 of the span from the support.
Span tables for flat roof joists to bs 5268 7 2 imposed loads of 0 75 kn m for maintenance and snow load are applicable where there is no permanent access no fixed ladder or staircase and most areas where the altitude does not exceed 100 metres refer to bs 6399 3 imposed loads of 1 kn m for maintenance and snow load are applicable where there is no permanent access no fixed ladder or staircase and most areas where the altitude exceeds 100 metres but does not exceed 200 metres.
These span tables apply only to flat roof and roof with a slope of up to 10 degrees.
The following easi joist.
Select floor or roof type.
For timber floors between homes.
Easi joist span tables.
The easi joist combines the lightness of timber with the structural qualities of metal.
Flat apartment floor.
The easi joist is a parallel chord truss utilising stress graded timber chords.
What is easi joist.
Rafter spans can be extended slightly beyond what the rafter tables suggest when there is a cantelever extending beyond the supporting wall.
These chords are plated together with a precision engineered and manufactured structural component called the metal web and when combined form the easi joist.
Timber to be covered these span tables do not apply to timber which is fully exposed to the elements.
You will be given a range of depths and centres that are available and also an indicative deflection result.
Due to variations in timber grades load sets support conditions and bearing widths the tables are not suitable as a design tool.
The following easi joist span tables are to be used as a basic guide to achievable joist span for given depth and spacing and should be used for estimating of feasibility only.
Easi joists are parallel chord trusses using stress graded timber chords plated together with wolf systems patented precision engineered metal webs ep 1 985 774 a1 a great alternative to standard carcassing joists and l beams.
Offering excellent versatility when designing floors roofs or walls.
Tables 1 and 2 in this chapter are derived from the trada technology ltd.
Easi joist specifier select the joist span and depth.
