Types and construction details of reinforced concrete belts in Kyiv
Several types of reinforced concrete belts are used in this type of construction; the choice depends on the building's number of stories, soil characteristics, and the materials used for walls and floor slabs. In general, four main types are distinguished in Kyiv construction projects:
Base monolithic belt
This is installed prior to the main foundation work, acting as a continuous strip that secures the base for support columns. A sand or crushed stone "cushion" is a mandatory component. The result is an underground structure that bears the entire weight of the building.
Plinth reinforced belt
This is installed on top of the already poured foundation. The width of the structure must match the width of the walls. This type is typically not installed for single-story buildings made of lightweight materials.
Reinforced belt for floor slabs
This is an intermediate belt that bears the load of the floor slabs. It is constructed along the entire perimeter, including over internal walls.
Reinforced belt for the roof plate (mauerlat)
This is the final structural element; it distributes the roof load and ties together the uppermost section of the walls. It serves as the base for anchoring the roof plate. Its installation requires an additional reinforced layer.
Everything you need to know about installing a reinforced concrete belt
The type of structure and its location are determined during the facility's design phase. Reinforced concrete tie beams are essential when constructing residential buildings, commercial premises, and industrial facilities. They are used in frame and timber houses built on monolithic foundations.
Specialists employ three basic methods for installing a monolithic reinforced concrete tie beam:
- Using removable formwork. This is the most cost-effective option, though it is relatively labor-intensive. At the start of the process, formwork is attached to the load-bearing walls. Reinforcement is placed into the resulting channel, and concrete is poured. Once the concrete has cured, the formwork is removed.
- Using permanent formwork. In this case, the channel structure is made of expanded polystyrene, which offers excellent thermal insulation properties. The main construction steps are otherwise identical to those for the removable formwork method.
- A combined method. Here, wooden panels are installed on the inside to form the channel, while a narrow foam concrete block is mounted on the outside. After the concrete cures, the formwork is removed only from the inner side.
When pouring the tie beam, great attention is paid to the concrete grade and consistency, which are selected based on the region's climatic conditions. The concrete reaches its initial strength four weeks after pouring.
Calculation of the cost of installing a reinforced concrete belt
RBK ALBA offers turnkey installation and construction of reinforced concrete belts (tie beams) in Kyiv and the Kyiv region. The cost of the work depends directly on the location and the perimeter area. For instance, an underground reinforced belt requires trench excavation and the preparation of a bedding layer. Overall, several parameters must be considered when calculating the cost:
- total length of the rebar framework (in linear meters);
- volume of concrete required for pouring (priced per cubic meter);
- quantity of rebar (priced per linear meter);
- binding wire (in kilograms) and a specialized rebar tying hook;
- fasteners for formwork assembly;
- wooden planks or panels sufficient for the entire length of the reinforced belt;
Additionally, the estimate includes costs for material delivery and concrete placement. Calculations also account for the purchase of crushed stone and sand, water usage, and labor costs for formwork installation and dismantling, rebar tying, and other tasks. The final price is specified in the contract agreed upon with the client.
