Metal Formwork Mounting Technology Construction
As you know, in the process of the construction of the foundation, it is simply necessary to equip high-quality formwork. This element is a kind of form for a concrete structure. In this case, it is important that the formwork has high-quality and smooth surfaces that will ensure the optimal geometry of the base of the house. Most often in construction used metal and wooden formworks.

It is worth recognizing that the formworks produced on the basis of wood are gradually going to the past. They have a lot of deficiencies, due to which the foundation may be far from such high quality, as planned.
As for the metal formwork, it is a truly modern solution that allows you to confident that the construction process will be as smooth.
Metal structures are now offered by many large construction companies. Ultimately, such products can serve at least a few years before its flaws will be rushed into the eyes. In this article, we will analyze all the main details related to the features and installation of metal formwork.
Main features of metal formwork
If we are talking about metal products, then it is often implied by a removable formwork, which can be used in construction an unlimited number of times. Moreover, most often this product can also be used to build the foundation, and to create housing walls.
Already ready-made metal formwork can be immediately used in the construction process. In sufficiently small construction, the owners are inclined to use wood formwork, which, of course, can only be used once. The thing is that the wood elements are fairly deformed and completely come into disrepair after enormous loads.
In large construction, it is simply necessary to use metal formwork, which easily withstand heavy loads, and also create the perfect surface of the concrete foundation.
Builders also make a choice in favor of metal formwork because they are folding. They can be stored in sufficiently limited spaces, as well as transported on small trucks. Accordingly, there should be no problems with transportation. Of course, this applies only to the construction of small buildings. In other cases, truly massive structures are used, which are delivered only with the help of special equipment.
Benefits and disadvantages of metal formwork
The following aspects include positive parties:
- Ideally smooth surface. Unlike all the same wood that can have a lot of irregularities, the metal formwork has a really high-quality and smooth surface. Accordingly, we get a qualitative foundation that will not have any external flaws.
- Elementary platform. For beginner builders a rather serious problem is precisely removing formwork after the fill of concrete. Wooden design in this case can prevent a lot of unpleasant surprises. With metal design, everything is elementary simply. With a proper approach (lubrication of surfaces), the formwork can be disassembled as soon as possible.
- Strength and rigidity. As we have already spoken, the metal base for formwork is the perfect option, since in this case we are confident in the monolithic design, which certainly does not collapse under the pressure of the concrete mix. This is an explicit advantage compared to wood formwork.
- Durability. The largest construction companies who regularly conduct construction of foundations, using the same metal casing. Of course, they have for many years practically does not deform, so you can be sure that the formwork will last a very long time. If there is a small building of a private house, you may want to rent a formwork at any organization involved in the construction.
Many modern metal formwork have special coatings that make it impossible to corrosion.
Of course, there is also a lot of other small advantages, but most of it relates to the specific use of certain materials as the foundation formwork.
If we talk about the shortcomings, it may be noted that the metal casing has a large specific gravity. This suggests that use metal product will be quite difficult in makeshift conditions. In large building formwork can be lifted and moved with the help of special devices, so that the problem concerns only those owners who want to spend the construction of their own hands.
I would also like to point out that the market can find aluminum casing, which have a modest weight than the other options. However, as it became known, in order to fix a formwork, it is necessary to use argon welding.
Already on the basis of the above information, you can determine whether it is necessary to use metal forms.
Types of formwork structures
You should know that in the building is used as much as 3 types of formwork designs. Each option can be used in a particular building, but about choosing the most appropriate type of care should be taken in advance.
- Large-design. In this case we are talking about the formwork which is assembled from the really big boards, as well as the holding of a special frame. Such a construction is used when necessary to pour concrete extensive base portion with very simple geometry. In most cases, such a structure consists of 8 panels, which form the tape boundary.
- Small-panel design. These formwork elements are used in the event that we have a complex geometry to create designs. Respectively, to form a concrete structure will require a lot of boards, but it depends directly on the construction of the scale, as well as the intricacies of the work done.
- Restored design. Accordingly, such formworks are advisable to use when building architectural structures, as well as small houses that must have original elements (columns, supporting walls for terraces).
Handy Metal Formwork Production
Immediately it should be noted that it is incredibly difficult to create a metal formwork. Most often the owners who want to build a house are used in this case wood. Based on wood, you can create a fairly good formwork, while forget about large financial spending. Do not forget that in case of problems, such a formwork can be easily broken and removed.
When erecting a metal structure, you can face a number of problem points. Do not forget that in this case you need to have a lot of special metal profiles, as well as devices that will allow fully copplain all the necessary elements. In addition, the cost of such a design is very high, so often there is a sense to purchase an already finished formwork directly from the manufacturer.
Metallic formwork
- Installation of formwork begins with the corner of the structure. At the same time, two metal shields are located for a start, and then the remaining elements can be installed. In order for the shields to keep, you need to install the supporting disclosures. By itself, the discolitions as accurately fixed the vertical position of the main element of the formwork, ensure the immobility of the design being created, as well as minimize possible wind loads, which will certainly be present when mounting formwork.
- In this process, it is best to use the disclosures that have an adjusting mechanism. With their help, we can control the layout of the support, while not paying attention to many building factors. As for the fastening of the splits themselves, often manufacturers are highlighted under these need special places (at these places it is possible to detect polypropylene nuts). Accordingly, the nuts are removed, the blocking elements of the formwork occurs, after which the nuts are screwed again.
- Formwork elements need to be highly fixed with each other. Most often, this is based on a dense screw connection. As an additional connection, you can use the most common wood elements. Boards can be placed on the surface of two shields at once, the field of which is securely secured.
- If we are talking about the installation of a metal formwork for the walls, it can be fixed directly based on metal reinforcement, which protrudes from a concrete foundation. In this case, you can use a thick wire that provides a completely good connection to carry out construction work without any problems.
- Immediately after installing each shield, the maintenance of supporting sinks occurs. This is necessary for the reason that under a large weight of the design, it can simply collapse. The disclosures themselves can be located either on the area of \u200b\u200ba particular shield, or between two shields. Both options are quite good, but the most important thing is to keep a step.
- Another important question is the creation of openings. When the foundations are erected, such solutions are not used as often, however, during the creation of walls, it is simply necessary. Accordingly, on the platforms of the openings you need to use a stripped panel element. Most often, similar components have modest dimensions, so there is simply no need for reference disclosures. If, for example, a window opening is created, then it is necessary to create a support zone on the side metal shields. In this case, it will be a kind of groove for non-standard on the dimensions of the shield.
Metal formwork reinforcement
Obviously, without reinforcement, during the creation of the foundation or the construction of the walls, it is simply impossible to do. For this procedure, the metallic formwork is suitable in the best way.
Often the reinforcement is installed along the entire length of the wall formwork. It is especially serious about the installation of reinforcement at the corners of the design. In this case, L-shaped retainers will be required that will protect the angle from the pressure of concrete. At the ends of the walls, a jack is used, which is necessary for stretching fittings.
As for the placement of long reinforcement in the formwork elements, 2 advice can be used here:
- Before making the fitting of the reinforcement, you can install a small tube, which has a slightly larger diameter than the metal rod itself. Already then you can still stretch the reinforcement through the pipe. It should be borne in mind that the pipe should be plastic.
- Another good option is to install fittings directly during the installation of metal shields. The essence of this ventilation is that here you can use a large number of rods that are gradually moving forward, thereby simplifying the building process.
Arrangement of Communications based on Formwork
It should be understood that the construction process, especially if it lies in the construction of the foundation or wall, may have a lot of subtleties. In this case, I would like to say a few words about the presence of communications in the structure. It can be ordinary pipes or a whole set of wires. You need to take care of this while creating a formwork.
To do this, we will need a small gap, which will be equal to the diameter of the pipe or any other communication. To this very clearance you need to install a small pipe. After the fill with concrete, the emptiness can be used in this place, which can be used for its intended purpose.
Some metal formwork structures support the analysis, already on the basis of which you can create the necessary opening. If such a procedure is not provided, it is only necessary to ensure the gap between the metal shields, and the extra area is filled with ordinary boards.
