Overlap: choosing the right home option

Types of overlap

Two types are considered:

2. profile Reinforced concrete

The monolithic overlap on the corrugated board is a fill using a special formwork. After the completion of the work, it looks like a finished ceiling and does not need any secondary finishes. Profiled sheeting plays the role of reinforcement.

Profiled overlap has a number of advantages. The main thing is the corrugated sheet surface, which increases the strength and high quality of the structure. By the way, this option reduces the amount of consumption of concrete and reinforcement.

The option of overlapping with the use of profiled sheet means the use of decking as fixed formwork. They will be concreted in the future. The metal frame, which has the structure of the columns, will be used as an additional support. This installation can use light building materials of low quality.

What are the load on the frame?

This method of overlapping is ubiquitous due to the fact that the load with the application of corrugated board is put on a strong frame of metal. Thus, the main weight does not go to the wall, which increases the endurance of the building.

Overlapping on the profiled sheet uses the following series of building materials:

• Penoblock;
• Gas block;



• Thermal insulation.

Specialists distinguish the overlap from the proflist for a number of advantages:

1. With the use of a strip foundation, the load on it must be reduced. When overlapping, all pressure goes to the frame, facilitating the walls and, accordingly, reducing pressure on the foundation.
2. This overlapping facilitates the use of the column foundation. This reduces the cost of construction. The head of such a foundation has a small grillage, its cross section corresponds to the thickness of the walls and the gap of the foundation columns.

Overlapping process with

profiled sheet The plan of monolithic overlaps using profiled sheet should be based on the rules of SNiP 2.03.01-84 "Reinforced concrete and concrete structures", SNiP 11-23-81 "Steel structures".It is important to perform the correct calculation of the structure using the following data:

• Parameters of the future construction;
• Calculates loads created by overlapping.

Using these data, it is necessary to determine the sizes of metal columns and beams. Support posts are made of metal materials( tubes of round, square shape).Additional blocks are made of metal beams.
The gaps between them depend on the type of flooring used. The length of the profiled sheet determines the pitch of the beams - the larger it is, the smaller the gap.

Calculate the pitch of the corrugated board is difficult enough. To avoid errors and gross errors, it is better to contact a professional or use special instructions that give the most accurate calculation data. It is necessary to be guided by correct representations about the used building material, about types of profiled sheets, their features and operational qualities.
