I need to know what the codes are on stairs? Treads@risers an hand rails ?for what degree of slope
They are the side members that the treads are fastened to, sometimes notched out to receive the treads.
11 risers will normally take 10 treads
They are the height it needs to be in order to make the desired number of treads connect the low and high points. That being said, Stair risers should be no more than 8" and treads should be no less than 11". Once your risers start being taller than your tread is long, you are building a ladder, not a stair. If you start at 8" for a riser and 11" as a tread, By shrinking the riser and adjusting the treads to fit you can get the steps to work out so that one consistent riser height can be achieved. One that will be in the 6-8" range. If you use risers that are less than 6", you should lengthen the treads. Example problem-- Lower floor is 6 feet lower than the higher floor. Keep in mind you always have 1 more riser than tread. 6'-0"= 72" You can make 18 each 4" risers (72"H /4"R=18 risers) and have a run of 34 feet using 24" treads. or you can make 12 each 6" risers and have a run of 11 feet using 12" treads. or you can make 9 each 8" risers and have a run of 7'-4" or 88" using 11" treads. You will always have at least one "given"-the height you need to traverse. From there it is just division and multiplication based on the 8" maximum riser and the 11" minimum tread.
A staircase is a series of steps consisting of horizontal treads and vertical risers that provides access between floors in a building.
@ risers are less than 73/4 inches high b. The width of treads does not strictly comply with codes c. The height of the risers by more than 3/8 inches
A Stringer is the long piece that the stair treads attach to on either side, and which goes diagonally up the wall. The handrails sit atop vertical supports which are secured into the stringer as well. As an addition, after Much researching, I conclude that the word has its origin in Italian - Stringa - which means to join together (and England was invaded by the Romans for a long time). And could also have some Danish (Viking) roots as the Danish word for Rise is Stigning, which could easily have been bastardized into the English Stringer. But as the Italians/Romans were known as stair makers, I'd go with Italian roots for the word. Michael Ross
The surface area of stairs is found by multiplying the length and width of one stair top and of the riser. This should be multiplied by the number of stairs.
Depends on where you are at in the assembly of the stairs. You could put spacers behind the risers or add a strip to the back edge of the tread. If the stairs are assembled and you can get to the underside you can screw a splice up under each tread and put a filler strip in from above.
It is a right-angled triangle where the height is the vertical leg (a) and the depth is the horizontal leg (b). a/b = tan of slope angle Slope angle = arctan(a/b)
No, tires have treads.
