Production and Assembly of Steel Structure

The production and assembly of such a steel structure , as described in this work, is one of the larger projects their small company has completed. Here, the mechanical properties of steel are important, which, through various tests, provide us with results on where the limits are that we must not exceed in practice. It covers the field of ** standard EN 1090/2**.

Solution and Method

The production and assembly of such a steel structure , as described in this work, is one of the larger projects their small company has completed. Therefore, they are pleased that, with combined efforts, they managed to complete a facility which they can proudly show to future clients in this field. The diploma thesis presents the process of ** constructing a steel structure using the example of the Lar commercial-production facility**.

In the introduction, they clarified what steel is and its main characteristics. Several historical facts about steel are mentioned, which show us steel production in the past and today. It also describes how we test the strength of steel and where the ** limits of irreversible deformations** are under loads.

When designing a steel structure, we must know what loads the facility will be exposed to.

Results

Here, the mechanical properties of steel are important, which, through various tests, provide us with results on where the limits are that we must not exceed in practice. It covers the field of standard EN 1090/2. An example of testing and obtaining a CE certificate is described.

The structure, which was built according to the standard and is materially divided into base material, filler material, protective material and fastening material, is confirmed within the scope of this standard and contains everything necessary to achieve it. Through the work, he verified whether all procedures for marking the structure with the CE mark were observed. This can be confirmed, as the procedure was followed according to all regulations.

Given that their company has only recently been in this system of certifying elements as products, with the help of his mentor in the company, Mr Šumak, he studied all the steps of obtaining a certificate and issuing a certificate for the described steel structure. All submitted documents required for the production and assembly of the steel structure were observed, reviewed and confirmed by the competent certification body.

All installed materials are tested and traceability is possible. The work describes areas in production where material and machine meet. It explains the work and discusses the procedures for preparation, processing and assembly of elements in production and then on the construction site. The production of the steel structure proceeded with some changes to certain elements, as the designer did not provide an optimal solution for the production and subsequent assembly of the steel structure.

Here, it is concluded that the bill of quantities forms for issuing the tender and subsequent production of the structure were partially incomplete. The drawings were also partially incomplete, so modification of the drawings by their company was necessary, followed by reconfirmation of changes to the static calculation. All changes to the structure were accepted and approved, so they were also observed.

In this way, they avoided mainly impractical work and thus additional costs in the production and assembly of the steel structure. In the assembly of the steel structure, mainly the ** anchoring of structural elements** into the concrete slab is described. Where they used two-component adhesive, which is very durable in terms of strength.

This is also described and confirmed by the calculation procedure in this chapter of the work. It also shows the curing time of the adhesive, depending on the external temperature. Special bolts are also presented, which were used in bolting the roof part of the structure.

Here, the roof gutter is meant. The bolts are tested and durable, and comply with the required regulations. They will also be used in the future, as they have proved reliable.

Their greatest task and advantage is that they enable us to have ** faster production** in advance and consequently also ** assembly of the steel** structure. At the end, a graph with costs is shown, which tells us that the structure was prepared on a good basis in the enquiry and tender, and during the construction of the steel structure there were not many additional costs with possible changes and various additional works. Some additional costs accumulated mainly in the substructure for bolting panel boards.

For the structure, however, the calculation was fairly accurate, despite changes to certain details. All received bills of quantities are the work of the company Projektiranje Alja s.p. As an investor, the company will most likely not face space constraints in the future, which it has experienced until now in smaller rented premises.

Through diligence, they have proved that it is also possible to build one's own production hall. For survival in this global competition, however, diligence alone is not enough, but new knowledge and innovations, as only a company with more new achievements always comes to life more quickly in the production environment. Their company also strives for this by showing who they are.

What they can achieve is enabled by clients and the market who trust them. In the work, he did not mention that a good final product is the sum of good ** preparation, precision, cooperation, and professional thinking of the people** who were present during the production and assembly of the structure. Great thanks go to their staff in the company and partners who participated in this project.

His goal in this work was to present the entire ** process of production and assembly of the steel structure** fairly clearly. To present the entire process as accurately as possible, he went into the details of preparation, cutting and processing of metal elements. The experience he gained in this project is also invaluable and he will be able to use it in the future in the next challenges that await them. He hopes that he has managed to describe the process of production and assembly of the structure as accurately and comprehensibly as possible, also to those people who are not engaged in this profession.
