In this article we will thoroughly study the process of manufacturing a concrete ladder with our own hands. It is worth noting that the concrete staircase with its technology resembles the construction of a concrete porch, the construction of which we disassembled in the previous article, but as an additional material we will analyze the step-by-step construction of the staircase - so let's proceed.
Concrete stairs with their own hands
The cycle of construction work associated with the construction of the stairs must begin with the calculation of the number of steps you need to know the height between the floors between which the staircase will be located, then this height will be divided by the expected number of steps that we want to get. It should be noted that the height of onestep should be about 150-170 mm, this will allow us not to seed on the steps and vice versa, if the step height is higher, climbing to the second floor will be very problematic, especially inour case, because we do not have very long steps. As for the width of the staircase, it will depend directly on the distance between the walls where the staircase will need to be inscribed if space is limited to a ladder with stall steps being built.
A staircase with runners is a variant of a ladder, when there is no opening between the two platforms, and this space is filled with steps.
The figure shows the optimum height of the
step. Step 1 - installation of the
ladder formwork The first thing we need to do is to set up the ladder frame. The frame serves as a support material for our entire monotonous concrete structure at this stage, note that the boards on our formwork need thick and very strong, especially if you make a massive ladder, because they will keep our entire structure after casting concrete.
Installation of the formwork for pouring concrete
Next, we set up the overlap of the formwork in the openings between the steps. Note that the formwork for the steps must also be anchored and strengthened as best as possible - this is to ensure that our frame is not deformed after pouring concrete,the staircase will go to smarku. Mount the formwork best with metal corners, such as you see in the picture.

formwork. Sample attachment for
formwork Step 2 - laying of the metal frame
At the bottom of our frame it is necessary to lay a metal reinforced frame - this will serve as an excellent element that will give strength to our design.
The reinforcing casing is tied together with a conventional
wire. Note that the cells between the elements should be of the order of 200 mm, and sometimes more than that is enough.
Reinforcing frame for a concrete ladder
For a metal frame metal bars with a diameter of about 15 mm are used, the yarns rest against the holes in the wall, and from the other end they are made almost to the end and rest against the formwork.
Step 3 - pouring the ladder
Fill the stairs, we advise you to start with the first stage, this is especially true if the concrete, how to choose the concrete read here, is done in liquid form.
Filling of the first and second stages of
By the way, because we laid a metal frame at the bottom of the stairs when filling the stairs, it is necessary to shake the concrete mixture with a conventional trowel, it will not allow air layers to appear in the structure and will not undermine the monolithic structure.
It is necessary to remove the formwork approximately 10 days after pouring, and the supporting poles that hold our frame are recommended to be removed after 14 days. Then there is a process of grinding concrete with a grinder and the staircase gets an attractive appearance, and how do you build your ladder?details in the commentary.
