A staircase is the union between the different levels within a structure, either for housing or for shops or offices, in any construction project from two floors to 5 the use of stairs is necessary (Practical Guide to Build a Wooden Staircase with the Perfect Measurements!). This element is constructed from three main components: stringers, steps and counters (or footprint and riser). The stringers are the 2 × 12 inch timbers that carry the weight of the people while they walk down the stairs, the steps are the sockets of the upper part (where you step), and the counterpanes are placed perpendicular below each step . With all this information, you can start building stairs yourself.
Instructions of step 1:
The result will be equal to the total number of steps on the ladder. The typical height of the counterbalance of each step is approximately 18 cm, but it is likely that you will use a different height in the final construction of the project (Practical Rule: If the total elevation is 241 cm, then divide it by 18 cm, the result will be 13.37 cm Round down to obtain the number of steps: 13)
Instructions of step 2:
Divide the total elevation by the number of steps to get the true height of each counterpart. To continue with our example, Divide 241 cm by 13, the number of steps; the result will be 18.5 cm. On the stringers, each step will have an atura of 18.5 cm.
Instructions of step 3:
The length of each step must not be less than 23 cm and must be at least 25 cm. Multiply the total number of rungs by the length of each rung: 13 rungs in total x 25 cm = 325 cm, the total length. The total length is the horizontal distance that exists between the start and the end of the staircase. In our hypothetical example, the total length is 325 cm
Instructions of step 4:
The spars are the pieces of wood that go diagonally below the width of the steps to support them. The rungs will be finally joined to this piece. Determine the length of the same form in which you find the hypotenuse of a triangle in geometry class:
Everything is translated in multiplying the length by itself (it elevates the length to the square), multiplies the height by itself (height to the square) and sum the two results. Then, find the square root of this sum.
- √ ((325 x 325) + (241 x 241)) = 405 cm
Instructions of step 5:
The secret so that the rungs do not sink or bend when you step on them, a wide ladder will need many stringers below to support the weight evenly. For safety reasons, the spars must have a clearance of between 40 cm 122 cm.
Instructions of step 6:
Get yourself a wooden board of 5 x 30 cm. Not yet the custom cuts; This will be inclined at an angle and this depends on the height and depth of the rungs.
Instructions of step 7:
Using a carpentry square, you will mark the height and depth of the steps. In the example you see in the image, 18.5 cm was marked on the vertical side and 25 cm on the horizontal side.
Instructions of step 8:
Modify the upper part of the spar to consider the total angle of inclination, since this will depend on the size of the steps. If necessary, consider any change, for example, the increased length when arming the stringers under a ledge.
Instructions of step 9:
Measure and mark each rung along the wood. Use the horizontal upper part of the crossbar as a reference point to determine (measuring downwards) a distance equal to the height of a step.
Instructions of step 10:
With a circular saw or a manual saw cuts the notches of the rungs on the stringers. If you use an electric circular saw, cut the edges of the marks and then use a hand saw or jigsaw to finish cutting.
Instructions of step 11:
Cut the end of the crossbar so that it is at ground level because cutting the protruding corner of the final part is much easier, simply mark a line parallel to the top end of the last step and cut it off
Instructions of step 12:
Do the test by placing the stringers in the position where your ladder will go; make sure the height is accurate.
Instructions of step 13:
Use the first crossbar as a template or pattern to follow the other stringers. Place the first finished crossbar on a wood or board. Then trace the outline of the first crossbar on the board. Then, cut where necessary.
Instructions of step 14:
Only two things, it ensures and stabilizes the stringers when installing the counters or baseboards. In general, the skirting boards are made of wood measuring 2.5 x 15.5 cm. Although you can do without them, screwing these planks vertically between each step will make the ladder look more beautiful, last longer and protect the wood ends of each cut stringer.
Instructions of step 15:
Place the boards to seal the sides and give an elegant appearance to the molding of the staircase. You can also install molding boards cut to the size of the step and install them just below.
Instructions of step 16:
If the staircase is for outdoor use, be very careful to make the wood a special treatment against the elements that may damage it.
