Sorry this is a bit long!

I am looking to take an internal wall out of the kitchen.
The wall is about 3/4 of the way down the length of the kitchen and provides
support for a joint in the ceiling joists. This is a single storey
extension, so the joists form part of the roof timber construction. The
roof is purpose built and not pre-fab'd A frame, so it has 2 angled beams
across the width of the roof space providing intermediate support for
rafters. Also it has 2 longitudinal tie beams going the length of the roof
space.
I have seen this style of roof before and believe it was common before the
introduction of the pre-made A frames.

I have had some plan designers in to draw up the general alterations, but
the details for the support of the joists was a bit sketchy. They mentioned
joist hangers to suspend the timber joist joint from a steel beam installed
in the roof space above the existing wall location.

The questions:

Does anyone have a link to pictures/suppliers of these hangers? I have
searched and searched without success!
Will this beam be carrying anything other than the weight of the ceiling and
ceiling timbers?


TIA

Phil
