Steel Beam Supporting Cavity Wall Detail

2 end of beam fixed to a masonry wall.

Steel beam supporting cavity wall detail. Supporting masonry to comply with eurocode 6 or bs 5628. M16 bolts fix the beam back to the side plates. Ends of beams can be laterally restrained using one of the following methods. Some of the beams were supporting existing timber floors.

Openings in cavity walls. The steel beam is hung from the rolled steel angle rsa with a side plate welded onto it. I regularly specify double pfc s for existing new cavity walls but i always specify steel spacers formed with angle one side of which is welded to 1 pfc and the other side is bolted to the other with a minimum of 2 no m16 bolts. This is important because the bricks need to be tied back cross bonded into the inner leaf of gable end cavity wall.

6 if steel beam to steel beam connections are required use appendix 6 5 c. If any area shown as void contains a staircase add 2m 2 to the effective area supported by any beam which supports partially or fully that staircase. 3 end of beam fixed to a column or a beam. If you install one large steel that picks up a double skin wall you should also install a cavity tray above it.

In these cases they were packed with oak timbers struts to spread the floor loads correctly across the rsj steel beams.

The designer is to ensure that the proposed detail adequately ensures that the end of the beam is laterally restrained. Steel beam calculations accepted by building control.

Walls that face driven rain are particularly vulnerable to water penetration. The minimum end bearing length at supports to be 100mm. Plan area of bonded masonry supporting steel beam to be greater than or equal to 0 1m. Cavity walls consist of 2 skins of masonry separated by a gap cavity.

Essentially your large steel prevents the natural gravitational passage of water. Above the rsj steel beam we dry pack the small gaps up to the first floor support with a semi dry strong 2 1 cement mixture this is compacted into the gaps between the beam and the first floors. The spacers are at a minimum of 750crs along the length of the beam including close to the support. Note that the wind post is formed from remains of the existing load bearing wall.

Figure 1 effective areas supported by steel beams. Steel beam end bearings to be located on substantial load bearing masonry walls or piers.
