Yes and it bears just 5cm on brick, in case of earthquake you will have tons of steel on your head.

The steel beam splice should be moment connection not shear connection, it will work as a simple joint which quite dangerous.

By this do you mean the bolt connection should be coming through the top of the beam vertically with a slice plate rather than what they've done here with bolts going through horizontally?

Great work. I have used dowels as well to move heavy stuff and it is magically easier. I do have a question: Is there a series of load-bearing columns beneath the I-beam ?

@OfficeBoyBuilder

2 жыл бұрын

Thanks! It's crazy how rolling a weight makes it seem lighter than lifting it. The SE didn't specify columns beneath the I-Beams, they are resting on the outer, structural walls of the building, which are 9 inches thick, so it's supposed that they are strong enough to bear the load.

Thank you for your videos. They are very helpful. I’m interested in knowing the size and length of this beam? I know all builds are different, but, mine has been specced with mid span support. It’s only 7m long so probably no longer than your one. Also, did you bed the outside wall padstone onto the wall plate?

@OfficeBoyBuilder

3 жыл бұрын

I believe the overall length was 8m (cut into 3 sections) and it was 203x203x52. Hope that helps mate! We sat the steel beam onto large steel plates which were on a bed of cement on the wall plate. We didn't actually use padstones.

@OfficeBoyBuilder

Yes this spanned 8m and took the weight of the floor and the mini stud wall that supported the roof slightly. Ours was spliced into 3, but you can get them as one piece. 8m is about the limit before there's too much deflection that requires a really big chunk of steel.

No washers only on adjustable slotted holes

You'll need to get a structural engineer to confirm that mate, the size of the steel is only one aspect... you'll need them to specify whether it can be spliced into sections or not, and also the weight per meter, which denotes the strength of the steel...while there are similarities between houses, each one could need a slightly different specification.

@peterpeterson9903

@Lynx L In this instance ordinary steel washers would be fine, assuming the fastener is torqued up correctly, the tension in the bolt, in a stationary application & not subjected to vibration or movement, would be sufficient to ensure good clamping force. The design intent here being that the bolt is under constant tension, if there are hot/cold cycles as long as the bolt always remains in tension, it basically is the spring. Don't forget, that is essentially how fasteners work, they rely on being stretched to one point or another to create an elasticity which pulls. Loads of fascinating science behind fasteners. Before I go, I will add, it is also very important not to overtighten as believe it or not, overnighted can be as dangerous as not tight enough. Once the bolt yields, it won't do much.

Why didn't you opt for a single long rsj instead of three separate rsjs?

@OfficeBoyBuilder

Finally, an educated comment from Science man. This is England. That's how they do things here. Structural engineers know what they are told. It is wrong, but this is how it is. Houses are built with bricks / blocks with no concrete pillars and collar concrete beams around. Load bearing beams and joists sit on bricks only. It's madness, but the reasoning is that it's not a ceismic prone land. However, when one day there is an earthquake, all those rsj and what not will come down crashing when's the bricks dislodge. It hasn't happen yet, but it will. Climate is changing, seismic activity can also shift. I will never build a loft like this, whatever the structural engineers and building control may say and sign off. I will do it properly, over do it.
