Floor Joist Supportfor Tile

In this scenario jim and rich install 1 2 cementious backer unit cbu resulting in at least an 1 1 8 thick.

Floor joist supportfor tile.

However you should take a little extra time to double check to make sure that they are all level. Now consider the same floor joist supporting stone tile flooring such that floor dead load is now 20 psf. So a 5 by 10 foot bathroom floor generally supports up to 2 000 pounds. Cut 1 5 extra on the beam side and 3 extra on the other side.

Planning on laying tile in our house. In extreme cases jim and rich have advised additional joists be put in place. Also when installing the joist supports you need to make sure that they are level. However the limit on total deflection is span 720 resulting in the need for total deflection to be only 0 50 half of the 1 00 value for span 360.

The floor framing for bathtubs requires special attention. The tiles are 7in x 20in. True floor joist span calculations can only be made by a structural engineer or contractor. A standard bathtub can hold between 40 and 60 gallons of water.

Hi a question regards setting out velux windows on a new extension roof basically do the velux s have to be spaced out so that the tiles fit as either a full or half tile to the edges of the velux. My question is should the tiles be placed so they are perpendicular with the floor joists or can they be laid parallel to the joists. If we use the same joist total deflection will be 1 50 1 25 0 25. Joists are spaced at regular intervals much like the studs in a wall frame.

This sample table gives minimum floor joist sizes for joists spaced at 16 inches and 24 inches on center o c for 2 grade lumber with 10 pounds per square foot of dead load and 40 pounds of live load which is typical of normal residential construction. Attach joists using joist hangers the project shouldn t take you more than a few hours. If the floor was built using the general 16 inch spacing you can expect a bathroom floor to safely hold 40 psf. 2 temporarily support the 3 joists that pass under the shower pan area on either side of that area.

They are covered with subflooring panels of plywood or oriented strandboard osb to complete the floor s structural assembly and create the solid continuous platform on which you install tile carpet or other finish flooring. Tile over wood subfloor. 4 add a single 2x10 header between the doubled joists to carry the 1 stub joists from the beam. 3 cut out the joists under the area to be lowered.

This provides sufficient support for most cast iron bathtubs which run under 500 pounds even when full. Plywood and osb are the two most common materials used for floor decking and typically they are 5 8 or 3 4 thick.
