Stairs made ​​of concrete with their hands , manual and manufacturing technology

In this article we will thoroughly examine the process of making concrete stairs with his hands.It should be noted that the concrete stairs of his building technology resembles the concrete porch, the construction of which we discussed in the previous article, but as an additional material analyze step by step the construction of stairs - so proceed.

Concrete stairs with his hands

construction work cycle associated with the construction of the ladder must begin to calculate the number of steps you need to know the height between the floors between which will be stationed staircase then this height will be divided by the estimated number of steps that we wantget it should be noted that the height of a step should be about 150-170 mm, this will allow us not Semianov the steps and vice versa at a higher altitude climb steps to the second floor will be very difficult, even more so in this case because it is we do not have stepstoo long.As for the width of the stairs, it will depend on the distance between the walls of the staircase where it will be necessary to enter if the space will be limited built staircase with zabezhnymi steps.

Staircase with zabezhnymi steps - a variant of the stairs when the two platforms is not opening, and this space is filled stage.

The figure shows the optimum height level

Step 1 - Installation of the formwork for stairs

The first thing we need to do - is to put a ladder frame.The frame serves as reference material for all our monotonous concrete structure at this point note that our formwork boards need thick and very strong especially if you are doing a massive ladder, because they will keep our entire structure after the concrete is poured.

Installing formwork for pouring concrete

Next, set the overlap of the casing in the gaps between the stages of note that the formwork stages must also, as much as possible be secured and strengthened - this is done to ensure that our frame is not deformed after castingconcrete, then all will go to the construction of stairs smarku.Attach formwork best metal corners, such as you see in the picture.

mounting Sample steps

Note that the side plates of plywood should also be attached or rest against additional reinforcing structures in this case the side boards are holding wooden timber.

final form fixing formwork

Step 2 - stacking metal frame

At the bottom of our framework is necessary to lay fiber reinforced metal frame - it will serve as an excellent element that will give the strength of our structure.

reinforcing cage ligated together using conventional wire

Note that among the elements of the cell must be of the order of 200 mm, and sometimes more than it is enough.

reinforcing cages for concrete staircase

to the metal frame used metal rods with a diameter of about 15 mm, pryatya run into the hole in the wall, and on the other end makes it almost to the end and run into the formwork.

Particular attention should be paid to strengthening the very first step - because it is on it will be sent to the biggest load after pouring.

Step 3 - Fill the stairs

Fill stairs we advise you to start with the first step, this is especially true if the concrete, how to choose concrete read here, is in liquid form.

Fill the first and second stages

way due to the fact that the bottom of the stairs, we laid a metal frame by pouring the stairs need to necessarily shake the concrete mixture using a standard trowel, it will not allow to appear a layer of air in the constructionand do not undermine the solidity of the structure.

Shoot formwork need about 10 days after casting and the supporting pillars that are holding our framework suggested withdraw after 14 days.Then comes the concrete grinding process using a grinding machine and a ladder gets priglyadny appearance, but as you build a ladder?details in the comment.
