Formwork for columns

    Huge importance in architecture have columns. They are erected both in large, high-rise buildings and in not very large, private houses. Most often, similar designs make from concrete.

    What it is?

    Formwork is a kind of frame, which poured concrete. Need it to give it the necessary form. This is very relevant in the case of formwork columns, because sustainability depends on its correct geometry. Formwork, as it is easy to guess, is used not only for professional purposes. Each person who intends to put on a plot of columns will definitely collide with it. Such a device has long been present in the convenience of builders, so today it is divided into several types and types. Each of them has its advantages and disadvantages and is excellent for use in the case for which it was created.

    Types of formwork

    Depending on whether it is possible to use a formwork design again or not, distinguished two types: one-time and reusable. Each of them is vertical because used to fill standing concrete structures.


    The essence of such auxiliary design is to use it once. Of course, this flows various pros and cons of such a formwork. Its cost will be sufficiently low when the pair of columns is erected. This is achieved by using simpler, and, it means, inexpensive materials. A huge advantage is the conditions for storing and transporting details of the formwork. Store them in the form of materials that are easy to transport to any place where the construction is planned, and if necessary, transfer the date of the construction of the columns, they will not give discomfort in storage places, because there will be no very many space.

    This type is used mainly for filling the monolithic columns of round shape. The fact is that the circle is the simplest geometric shape. Those materials from which one disposable formwork is produced is enough in order to bring them into a circle. For more complex columns, more rigid and durable materials will be required.

    The minuses of this species is a fairly high price with a frequent construction of columns. The price is very small, however, in the case of wholesale purchase, the situation is completely changing. Therefore, this kind of formwork is perfect for private construction, where there is no need to build a large number of columns. The subspecies of the disposable formwork is the unavailable type. It is used as a decorative element in the ready-made column.

    Used extremely rare, but it is appropriate enough with proper use.


    The formwork of this species is distinguished by its relatively high price, however, it is completely captured when using it in order for which it originally and thought – reusable construction of columns. Of course, the obvious advantage of this species is cash savings, by more payment initially for less fees in the future. However, it is profitable for those who are professionally engaged in filling columns.

    The buyer of a multi-sized formwork should understand that the maintenance of such a design is harder than one-time. So, the formwork of reusable use is harder to transport from place to place, and this is added to this and the fact that it will be constantly needed somewhere to store. Despite many inconvenience of this species, its huge advantage is the possibility of filling columns of the most bizarre. This is what is impossible to implement with a one-time type.

    It is appropriate even for pouring pipes under the pile, which can be carried out with one-time formwork, but it will be more expensive than with a multi-part.


    Formwork also differ on the materials of their manufacture. Depending on which its parts will be made, its properties and purpose will change.


    This material is used for the manufacture of disposable formwork. Its simplicity allows you to achieve the minimum price of this kind of products. Sometimes the cardboard is replaced with a special, impregnated paper. Them both are easy to dismantle after concrete freezes. Minus paper formwork lies in the fact that build complex columns using cardboard will be problematic, so it is better not to use it for such tasks.


    Successfully practiced in private construction. It’s all about the availability of materials – any not very large boards or ordinary plywood will be suitable. To put the form of the fill will not be difficult. And the column can be made both round and with sharp edges in the form of a polygon. But taking into account the fact that it is still a tree, and not solid, but consisting of boards, you will have to use an additional one interlayer between concrete and formwork. For the construction company, this type of material will not suit, as it will make difficulties in the storage and transportation of components.

    The construction of the same design quickly quickly, if one or two pieces is required, but in large quantities there will be problems with spending a lot of time.


    Indispensable in professional construction. Such a formwork consists of separate components – shields that are going on the site of construction. When using the so-called universal shields, workers have a large range of tasks, because the number of shields can be any, and therefore, the height of the column erected can also be diverse. Such material allows you to build high and wide columns. However, it causes difficulties in storing and transporting parts.

    Metal formwork is a reusable view, and due to its strength, it is capable of long period of performance.


    This type, in contrast to metal structures, can not withstand a large pressure from the solution. Therefore, it does not apply to the fill of large columns. But This material is very light, so it is easier in its installation. Also, in addition to polygonal types of columns, using this formwork you can pour round and oval columns. Mainly used for professional purposes in building low houses. This determines the low price of such products.

    For a large column, this species will not suit, because there is a possibility that the formwork simply will not stand the pressure of concrete.


    We can say that this species has its own ancestor in the form of a metal formwork. In fact, the combined design also consists of steel or aluminum, but with the addition of wooden elements. Or, on the contrary, holding elements can be made of wood, and their ribs – from metal. In general, combinations of various materials are made either in order to reduce the price of goods, without lowering the quality, or to increase the reliability of the formwork without much growth in the price of it.


    Concrete structures have different sizes. For wooden formwork, this is not a problem – it is enough just to add more boards and zoom in the diameter of the product. But for metal and combined it is an important point. If the shields are too small, then use them to create large and wide columns will not work.

    The shield size determines the largest polygon area, which they can form. The most popular are 300×300 and 400×400 sizes. The height also depends on either the length of the board or plastic in the case of the formwork of the sameb, or on the number of shields in the case of a metal formwork.


    Properly selected formwork – the first step to good columns. To make it with your own hands or in the enterprise, you should perform a small and simple instruction. However, more accurate actions can be taken only on the basis of a plan or drawing. It is necessary for the end result to be worthy.

    The very first thing to do is to place a formwork design in the right place. If universal shields are used, then it will be slightly harder. First, the first guide details on the diameter of the future column are put. With the help of special tools – riglels, the divosers they align. This action is made with subsequent levels. You need to connect the shields with each other with special locks.

    It is worth considering that With the construction of high designs, scaffolding will have to use, and if possible, the lifting faucet. After the formwork is installed, the reinforcement stage begins. Poles are inserted inside, which are designed to strengthen the future concrete. They are clogged to the ground to such a condition in which they will be able to stand all the time of pouring the columns.

    At the end of the installation of formwork elements, you can pour a concrete mixture. When using shields, this task is simplified for high columns. It is enough just to open the shield at the right level every time, and pour concrete through it. Fill the formwork will not be much labor.

    Dismantling begins when the whole concrete will freeze. To do this, you will need to shoot shields one by one, starting on top. With any other formwork, it is easier to do this, for example, in the case of a wooden structure just to remove the boards included in its composition. Formwork for columns – an indispensable thing in construction. It exists in a wide variety of types, which allows for a specific task a specific formwork.

    Its installation can be made by both a private person and a construction team.
