Concreting grillages: arrangement of piles, formwork and

Pile foundations became popular in ancient times, as they not only had good stability on the ground, exposed to water, but also saved a lot of time. In modern construction, such structures are also used quite often, but with a number of improvements and improvements. At the same time, concreting of the grillages is one of such innovations, which significantly increases the technical characteristics of this structure.

Phased preparation process

First we need to say that all work with the foundation should be carried out strictly according to the project. The fact is that there are a lot of varieties of such structures, which have their own unique features and are designed for a specific type of building. Therefore, intending to create a pile-grillage foundation for aerated concrete or other basic material, first of all, you should be familiar with the project. (See also the article Partitioning of aerated concrete: how to do.)

Piles

• There are many different types of piles. However, most of them are designed for a specific type of soil. Therefore, your choice should be oriented with regard to the load of the building.

• It is worth noting that the foundation on screw piles with a concrete grillage is created according to a special plan, which is called a pile field. It takes into account all the loads and shows the exact distance between the supports.
• Some masters recommend immediately planning the land on the site, since the remaining mounds can interfere with further installation.

• It is worth noting that the concrete grillage on screw piles or the like is entered into the project as a single foundation. It is impossible to use separate elements of such a construction for the manufacture of another structure, even if it seems almost identical.

Tip! When making a project independently, special attention should be paid to a bunch of all the supports and their subsequent concreting. Professional masters recommend entrusting such work to specialists, since even they may make mistakes in calculations, especially on complex structures.

Formwork

• At this stage, the installation manual recommends the manufacture of formwork. At the same time it should be tied up not only to the piles, but also to make supports on the ground.

• To create such a design is best to use sheets of moisture-resistant plywood. If they are not, then you can apply and boards, but you must create a sealed seams so that moisture does not flow out of the formwork.
• When it is necessary to create reinforced concrete grillages, professional craftsmen recommend first making a pile dressing and only then fill the formwork with reinforcement. At the same time, it is not boiled, but tied with steel wire.

• To control the level of placement of the metal in the concrete casting is best to use special coasters that fall to the bottom.
• It is worth saying that experts recommend bandaging metal piles in any case. However, if it is not in the finished project, then you should immediately abandon it.

• It is important to remember that not only the monolithic reinforced concrete grillade needs precise positioning, but any other element of the cast foundation. Therefore, in the manufacture of formwork, you must use the measuring tools in the form of a level and respond.

• It is also important to note that you should not create additional sections, or branches, motivating this with too long materials that you do not want to cut. Otherwise, it may be necessary to cut the reinforced concrete with diamond circles, which has a rather high cost.

Tip! Professional masters recommend laying a film on the bottom of the formwork, which will serve as a waterproofing and at the same time will not allow the liquid to flow from it.

Fill

• Many builders do not attach much importance to this stage, since they believe that it is enough just to pour the solution into the formwork and smooth it out.. However, there are a lot of different features.

• First of all, care should be taken to create seats for the main structure or columns.. To do this, install the pipe or special liners. If this is not done at this stage, then diamond drilling of holes in the concrete may be necessary.
• Next you should order a solution. It is worth noting that some masters prefer to do it themselves, but this is permissible only in cases where it is impossible to fit the machine to the structure. The fact is that enterprises manufacturing concrete strictly comply with all the necessary proportions and, if desired, the customer can add special additives to it that significantly improve its technical characteristics.

• The finished mixture is poured in one run, leveling its surface on the formwork. It is also worth using the water level to make the area smooth and even.
• To speed up the process of solidification, professionals advise to use rags soaked in ammonia solution.. It is placed on the surface and covered with a film. It is worth noting that the price of this method is small, but it is thanks to him that you can significantly reduce the time after pouring before the construction of walls.

• After the concrete has completely dried formwork, it is possible to disassemble and trim some drops with the help of cement mortar..
• Then this part must be further warmed and protect the concrete from moisture from the sides and from above.. This will significantly increase the life of not only the cast base, but also the entire structure that will be on it.

Tip! Experts recommend adding plasticizer and antimicrobial additives to concrete. Also, if desired, higher grades of cement or other additional components may be used.

Conclusion

After reviewing the video in this article, you can get more detailed information about how the grillage is made. Also on the basis of the article proposed above, it should be concluded that this process is completely based on the project and is strictly prohibited to deviate from it.
