Truss glide shoes for raised tie trusses

They’d need to be pretty meaty, and supported at the ridge by a steel probably. That’s what trusses generally avoid the need for, as they can’t spread.

Impressive What's the rationale behind doing it with raised tie trusses? Nowhere to support the other end of a structural ridge, or purely build speed?

A raised tie truss usually comes about when the wall plate and ridge heights are pre-determined which in turn means that in order to get a decent height ceiling, the tie needs to be raised above the level of the wall plate. Matching an existing roof pitch also, can have a bearing

What do you think of these glide shoes, if one nails into the top holes, surely it defeats the purpose of getting these if they can slide. The ones with the same top holes as what's on these would help the movement.

You are meant to nail into the glide holes only until the weight of the roof is in place. You are then supposed to add the remaining fixings once the roof is on.

These type where confusing me because ive seen others that have the glide long hole only they have 3 the same. Why is there different types

So, your advice would be to nail the long hole while trusses are installed and when the roof is loaded with battens, felt and slates then is the time to nail the other holes. What about the snow and heavy wind loads in the future, surely they will contribute to bowing of the walls on a raised tie truss.

the first pic i posted with the truss clips are for scissor trusses on other part of the roof.
 
Shouldn't all this be part of the design by the specialist truss supplier :?:

The truss suppliers supplied the trusses plus the diagram of bracing however i was expecting the truss slide shoes with the 3 longer holes rather than one long and 3 small.
 
Why not ask the truss supplier
That's what I do. Rarely are any of our jobs similar so neither are the roofs. I have good rapport going with a fella from Trussform (Matt) really knows his onions and can visualise most things I blab to him down the phone.
