We mount a glass-type foundation for columns: Monolithic and prefabricated

Stability and strength are the two most important indicators that determine the performance of a structure.

The foundation of the glass type is usually equipped with the construction of industrial buildings.

It is especially important to use it in the construction of one-story columns, which serve to strengthen the floors. The foundation glass has an impressive mass, so installing it yourself is not feasible in practice. However, when using special equipment, this procedure is greatly simplified.

Moreover, the process does not take so much time, and takes place in several stages. The use of especially strong concrete allows to obtain wear-resistant elements that are not afraid of various aggressive influences.

Glass-type foundation: characteristic features

Modern glass-type foundations are made of high-quality reinforced concrete. They can be attributed to one of the varieties of the well-known columnar structures , but the former are characterized by better stability.

They are not just pillars, but a kind of large "shoes" made of reinforced concrete.

They are installed in specially prepared pits, where the surface is thoroughly compacted beforehand.

What are their features?

It cannot be said that in modern realities this method is used so often. But, among others, it has the right to exist.

Main areas of application

Glass-type structures are used for:

• the construction of relatively small production facilities ;
• construction of individual residential frame houses;
• for the construction of reliable racks for basement, condensation and basements.

Types of glass foundations

There are two types of glass foundations:

1. Monolithic;
2. Prefabricated.

It is easier to manufacture and more convenient to use monolithic structures. They are characterized by the presence of a horizontal surface, and for prefabricated, a sloping surface is typical.

But, in both versions, the monolithic pillar is located, in relation to the glass, higher.

Column glasses are made of high-quality concrete mortar with the inclusion of reinforced reinforced frames. Such structures have excellent stability, have an impressive service life.

What does the structure consist of?

In the structural state, the structure contains the following components:

• A base or foundation slab placed on a crushed stone and sand cushion prepared in advance;
• A special element, in shape glass-like patella;
• Columns are the most important supporting parts;
• Strong concrete pillar. Its main function is to reliably support reinforced concrete beams, which account for the bulk of the structure.

When all the listed elements are assembled into one structure, a prefabricated glass-type foundation made of reinforced concrete is obtained. Its distinctive feature is the sole, which can have a different area, but usually does not exceed 55 square meters. m.

Advantages and disadvantages of glass bases

What special advantages do such glass bases have?

• Columns for them are manufactured industrially, which ensures their durability, high quality and reliability;
• If available the necessary equipment, their installation is quite simple and does not take much time, which allows you to speed up the installation time and reduce the cost of money.

The disadvantages of using this type of bases
include the need to use special heavy equipment:

• both for the delivery of products,
• and for their placement and installation.

Currently, various reinforced concrete supports are actively used: the difference lies in their size and weight.

Installation of the foundation

For the construction of glass structures, it is important to adhere to the prescribed standards. The installation process is not so difficult if you strictly adhere to a certain sequence of work.

Steps for the construction of the foundation

1. Competent preliminary preparation of the soil.
   It must be well aligned and marked.

   The fact is that reinforced concrete beams will be placed on it, which are strictly forbidden to be displaced.
   If the characteristics of the construction site do not allow this, then it is quite possible to add the brought soil and tamp it properly.

2. Soil compaction.
   When the soil is sufficiently prepared, you can move on to the pits that are dug in predetermined marked places.
   The bottoms of the finished pits are compacted and compacted with gravel.

3. Next comes the turn of installing the blocks.
   Care must be taken that the surfaces of all elements to be installed are in a strictly horizontal plane. They use various devices for this, for example, a level or the usual building level .When all the elements used are installed, it is required to clean their surface from all types of contamination.

A correctly installed glass foundation evenly distributes the loads from the structure over the entire soil surface.

An important condition for this is soil resistant to subsidence, heaving, deformation.

Such its characteristics are necessary for the absence of subsequent subsidence of the structure, the formation of cracks. In other words, they provide the building with reliability, increase its possible service life.

Compliance with technology

In order to avoid errors when installing the base , the necessary measures must be taken to provide it with the necessary strength.

• It is required to use concrete grade M200 (or higher quality) , which is necessary for high bearing capacities and proper strength of future supporting pillars;
• During the construction of a structure, a water absorption level of not more than five percent should be ensured;
• All structures are installed only after they have acquired the necessary strength;
• Mandatory reinforcement of the columns with special steel reinforcement;
• The thickness of the mortar around the metal rods must be at least 3 cm;
• Cracks are allowed after drying no more than 1/10 of one mm;
• During the installation process, after the support columns have been installed, remove all existing special mounting loops.
