Assembly formwork - let's get acquainted with
Such an important thing in construction is a combination of parts that form after assembly a strong, solid and even structure that does not buckle or fracture under the weight of concrete, which allows to pour concrete of different shapes with almost perfect angles.
Like everything in our life, prefabricated formwork has its positive and negative sides. Naturally, the advantages of this simple invention are enormous. Perhaps the most important plus is the speed of assembly. Indeed, such a formwork is made very quickly.
The second plus is reliability. Having correctly established such formwork, you are 100% insured against possible ruptures, bends and other troubles that arise under the influence of the mass of concrete. It is also worth noting that with this invention, concrete can be shaped in a variety of forms without losing the integrity of the structure.
These are the most important pluses, the rest is better to evaluate already during the use of this formwork. Of the minuses is worth noting the relative high cost of construction, but it is solved in a simple way. This formwork is not necessary to buy, it can be rented.
Reusable formwork - prepare for construction
Having decided on the next construction site, you should make some amount of preparatory work. First, you need to clear the site for construction, provide space for auxiliary equipment for mixing concrete, and also equip quick access to all tools. Most likely, you will be able to install the entire structure in one day.
Now go to the marking of the future concrete foundation, size the edges, observe all the corners, and then drip a pit for concrete. Reusable formwork is installed directly after excavation. For the installation itself, we will need the wrenches and, possibly, the drill. Everything else is part of the formwork.
Demountable formwork - assembling the
constructor The very process of setting the formwork is extremely simple and reminds the children's designer, only on a larger scale. The main thing to do everything in turn, reusable formwork does not like rushing. Once you have installed all the elements, make sure the location is correct.
Measure the center and corners, after which you can safely fill in the concrete itself. After it is poured a rather complicated question arises: how and when to remove formwork? There is no exact answer to this question, so you need to act, so to speak, with a margin. The fact that the concrete freezes depending on the brand, the higher it is, the faster it will solidify. Also important is the amount of the concrete itself and the temperature regime.
So that everything was fine, and there were no surprises, the formwork should be removed after a minimum of 30 hours. Ideally - 48 hours. We pick up the wrenches and begin the process of dismantling. Since we collected the formwork from the bottom up, the bolt behind the bolt, then it is necessary to disassemble it in the opposite direction, from top to bottom.
This will help to avoid possible discharges, which can lead to a sharp runoff of the rack and washer, which promises quite dangerous consequences, since on one such a supporting rail can press several tons.
In general, even untwisting properly, be careful and stand sideways so as not to injure yourself.
After you have removed all the bolts, you must dismantle the formwork plates yourself. If they do not depart, then a powerful hammer blow solves this problem. In order not to run after the hammer, it is desirable to immediately tap every plate. This will ensure a quick dismantling. That's all the secrets, you'll agree - it's easy.
