Steel Beam Supporting Cavity Wall Detail

Figure 1 effective areas supported by steel beams.

Steel beam supporting cavity wall detail.

Steel beam end bearings to be located on substantial load bearing masonry walls or piers. Some of the beams were supporting existing timber floors. The minimum end bearing length at supports to be 100mm. Walls that face driven rain are particularly vulnerable to water penetration.

The spacers are at a minimum of 750crs along the length of the beam including close to the support. 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. Steel beam calculations accepted by building control. 3 end of beam fixed to a column or a beam.

In these cases they were packed with oak timbers struts to spread the floor loads correctly across the rsj steel beams. Supporting masonry to comply with eurocode 6 or bs 5628. Openings in cavity walls. M16 bolts fix the beam back to the side plates.

1 end of beam built into masonry wall. 2 end of beam fixed to a masonry wall. 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 steel beam is hung from the rolled steel angle rsa with a side plate welded onto it.

Ends of beams can be laterally restrained using one of the following methods.

Essentially your large steel prevents the natural gravitational passage of water. 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. Table 4 size of steel beam supporting floor. If you install one large steel that picks up a double skin wall you should also install a cavity tray above it. The designer is to ensure that the proposed detail adequately ensures that the end of the beam is laterally restrained.

Plan area of bonded masonry supporting steel beam to be greater than or equal to 0 1m. Note that the wind post is formed from remains of the existing load bearing wall.
