Floating formwork (horizon) is one of the most important components of the construction process. It is a necessary element that provides convenience and efficiency of works during construction of the building. Decking allows you to make a floor made of monolithic concrete, which has an extraordinary strength and durability.
In this text, we will consider the issue of floor formwork, focusing on its main functions, types, requirements for materials and installation.
Functions of the floor formwork
Floor formwork has several important functions. The most important of them are preserving the shape of the future overlap and guaranteeing the quality of works. Decking allows you to make a floor made of monolithic concrete, which has an extraordinary strength and durability.
In addition, the formwork of the floor allows to ensure accuracy and uniformity of load distribution on the future overlap. Decking also performs the function of ensuring the safety of employees working on construction, protecting them from possible injuries.
Types of floor formwork
There are several types of floor formwork, which differ in material, with of which they are made.
- Wooden formwork. This type of formwork is very common and is used due to its availability and ease of installation. Wooden formwork is usually used to create monolithic floors of medium height. Formwork is used to create boards, bars and tripods. However, wooden formwork has its drawbacks - it is not reliable and has a limited durability, so it often needs replacement or repair.
- Metal formwork. Metal formwork has high strength and durability, which allows it to be used to create high monolithic floors. It usually consists of metal panels, which can be connected using special fasteners. One more the advantage of metal formwork is that it can be used more once, which reduces the cost of construction.
- Plastic formwork. Plastic formwork is a new type of formwork, which is well adapted to use in various conditions. She has a lung weight, which allows it to be easily transported and installed. In addition, plastic formwork has high strength and durability, which allows use it to create monolithic ceilings of different heights.
Requirements for materials and installation
Requirements for materials
- Strength: the formwork material must withstand large loads acting on it during concrete pouring. Depending on ceiling height, the formwork material must have the appropriate strength.
- Durability: the formwork must retain its properties and form during prolonged use. It is important that the formwork material is not was damaged by water, sun and other factors.
- Watertightness: the formwork must protect the concrete from penetration of water and other substances. This will help prevent quality degradation concrete and increase the life of the building.
- Lightness: formwork material should be light to be able to was easy to transport and install.
Installation requirements
- Reliability: the formwork must be correctly installed and securely fastened to ensure maximum stability and strength structures.
- Evenness: the formwork must be even and conform to the plan designing. This will help ensure the correct shape and size monolithic floor.
- Hermeticity: the formwork must be closed and hermetic so that prevent leakage of concrete during pouring of the monolith. If the formwork is not airtight, concrete can leak during pouring and create defects in monolithic floor.
- Ventilation: the formwork should be sufficiently ventilated so that provide fresh air, remove excess moisture and avoid formation of condensate. This is especially important in conditions of high humidity or when the ceiling is in the ground.
- Materials: the formwork must be made of quality materials materials that can withstand the weight of concrete and not be damaged under installation time. I usually use it as formwork material i.e wood, metal or plastic.
