Blocking. Cross Blocks, or X Blocks/Bracing. Depends on what region of the country you are in.
If you're installing hardwood floor boards over a strong 3/4 inch plywood sub-floor, then yes, you can install the hardwood floor parallel to the joists. If your sub-floor is weak, then you should fix the subfloor.
floor joists and they sit on bearers
If your house is wood framed with wood joists, the shaking may be caused by floor joists being too small. This will cause the floor to sink whenever a person walks across the room. Floor joists should be size by an experienced carpenter, architect, or engineer to prevent movement.Another cause of floor movement may be insufficient bracing between the floor joists. This will cause sagging and twisting of the joists.There are several solutions that require the skills carpenter. New joists can be added beside the existing joists to strengthen the floor. Another option is to add one or more beams and columns in the room below the floor. Or blocking can be added between existing joists to add support.
That depends on (a) the mass of amount of pressure applied by the tonne - how much area does it occupy and (b) the strength of the joists - the boards the floorboards are laid across. it also might depend on whether the floor is at ground level or not.
answerYou would lay timber floor joists acroos the the size would depend upon how high you need to raise the floor. Then you'd lay floor boards over the joists. the joists would be layed every 400mm and would require noggings to reduce movevement and 'creaking'. The floor boards should be of a tongue and groove type for the same reasons. The cheapest floor bords are made of chipboard and are 8' by 2' and they should be glued.If you wanted to raise it a matter of a few inches then you could just screed over the top of it. If you wanted just a few mm then a self leveling liquid can be applied.
Different situations call for different joists. Generally floor joists are 2 x 12.
That depends on the sise and the type of timber the floor boards are made of, However standard practice with flooring is 450mm centers or 600mm centers if the boards are thicker to allow for the extra 150 millimeter's
Yes. Rafters and flloor joists do not have to run the same direction.
Joists resting upon sills and girders
Essentially, you fit floor boards to the ceiling joists. The more common option is to use 4' by 2' chipboard tongue and groove floorboards, using screws and wood glue on the joints. This will stop creaking.
That depends on how well supported the floor is and that depends on how far apart the joists are placed. The closer they are, the more weight can be supported.
