Formwork for staircases from concrete

Formwork for stairs is a special fencing devices temporary use, which plays a role in the formation of reinforced concrete stair design.

How to do formwork for stairs by yourself? ↑

To perform such a time consuming and difficult work should have patience, knowledge, construction material and necessary tools.

Knowledge of the technical part of product design ↑

First, create a drawing of the future building formwork. The designated location and the calculated load on the suspension.

Calculated quantity of consumables, preparation tools and equipment.

Consider creating formwork for monolithic stairs. We will need:

• Prepared by edged boards 25-30 mm;
• Waterproof plywood – 20 mm;
• Rebar is ribbed in diameter of 10-20 mm;
• Bars with a cross section of 10 10 mm.

All parts of the future of design must be stykovanii and customized to each other without a variety of slots and recesses.

Begin the Assembly fixture. For this you need to use screws, do not recommend the use of nails, as will difficulties at the time of their extraction from the boards.

Check the availability of construction tools:

• The level of customization of products
• Plumb
• Mechanical hand saw or jigsaw electric
• Drill bits or screwdriver set
• Hammer.

During installation, the backups need to be very vigilant not «on the off chance» to record logs, concrete structure weighs quite a lot that can damage the entire formwork.

Reinforcement ↑

Being done to increase the strength of the product, most often used of ribbed rebar. Its numerous elements are twisted soft wire.

Pour a monolithic concrete stairs need a single step, starting from the bottom to the last top step. To avoid witecki solution of the formwork, it makes it more dense, due to the impurity sites. To eliminate in the concrete air cavity is necessary in the work to apply the electrovibrators.

After complete curing of the concrete and test the strength of the staircase formwork is dismantled.

Formwork for stairs marching ↑

Installation of formwork stairs marching should meet strict guidelines:

1. To prepare the two side boards 20 cm wide, to celebrate the future degree;
2. Fix with screws the bars, which will be based podstupenki;
3. When you narrow the March will be enough to use a 40 mm thick boards;
4. Strengthen the construction of an additional focusing.

Before pouring concrete, drive stakes in the ground, and after complete drying them a bit of rasp, removing all the bumps on the surface layer. Formwork for concrete staircase manufactured with a standard height regardless of the number of steps and design.

Installation of the formwork for the stairs with his hands ↑

Constructing formwork for stairs, which is between two walls that are against each other, you must do the following:

1. Make the layout of the walls, where there will be stairs.

2. Attached to the wall 15 cm nails wooden rails of I-beam for formwork.
3. Installed the rack, locking them in concrete. Hammered them wedges, which are fastened with screws spacers.
4. Stacked formwork of boards, put the roofing material and sanding the ends.
5. Next, make the reinforcement, twisted rods with wire.
6. Now start processing steps. Take the Board and fasten them to the wall using dowels.
7. Watch carefully that the right side of the Assembly against an intermediate edge metal corners. The shotgun fasten long nails.
8. Building level measure all planes correct errors.
9. If done correctly and precisely, fill the product with concrete.

Formwork for spiral staircases ↑

A spiral staircase is the most difficult and time-consuming to manufacture shuttering for her. The technological process is complicated by the fact that each element of the design need to do separately.

Try to understand main points of a formwork for spiral staircases.

We need sheets of plywood for laying and forming a trapezoid. A curved surface can be formed rods or pieces of thick plywood.

1. Do stands from bars with cross section of 100 by 100 mm in the interval 40-60 cm.
2. Mount well fix more logs so that the weight of the formwork and the rebar had to support design, avoid the irregularities and the formation of air locks.
3. It is important to consider: 3 m beam 100 by 100 mm can hold weight of 150 kg.
4. Knowing this, calculate the number of required props. To enhance the design you can still install the crossbar.

So the formwork for spiral staircases made of concrete securely fastened, fixed, and verified. If the ladder will be with the railings, before pouring concrete for fasteners, you can install a special plate, of which subsequently will form the side walls.

Types of formwork for stairs ↑

• Mobile. Which can be used several times, it can be disassembled and moved. This kind of the most profitable and prevalent in construction sites and large-scale enterprises for the manufacture of the frame for the stairs.
• With a film overlap. Tough, easy to create, easy. The design is made according to the number of steps of the staircase, is covered with special plastic film. Possible re-use in concreting.
• Wooden floor. This formwork needs in special clamps, placed initially one Board is fixed, then the other, this is done to ensure that they are tightly connected and there was no space between them. After fixing them with nails still requires additional wooden wedges.

So we learned today how to assemble the formwork for the staircase alone, having a pre-generated drawing of the design scheme, the required list of construction tools and materials.
And so, we learned that the work on establishment of the formwork for the various types of ladders should be done in a strict sequence:

1. To assemble the structure
2. To make the reinforcement frame staircase
3. Concreted prepared by the steps

The dismantling of formwork do not earlier than in three to four weeks. Let the whole design dry and will shrink.

Well, that’s all! Your staircase is ready for finishing work!
