One of the most important new executive methods for a variety of construction and industrial structures that are fully regulated in terms of engineering is steel structure. Wooden skeletons were used before the steel structures were used for the base and support of the buildings. But today, with the advancement of technology and engineering science, most steel structures made with different types of steel are used for the skeleton of the building. Because of the important role that the steel structure plays in the building, its installation should also be considered like the design. Some errors and negligence during installation will never be compensated and this determines the importance of learning to install steel structure for workers in this field.
Considering that today most structures are constructed with steel structure, teaching the installation of steel structure to people who want to work in this field is one of the most sensitive in the construction of the building. If done properly, the safety of the building and its resistance to natural disasters such as floods and earthquakes will increase. However, in case of inaccuracy and awareness when installing the steel structure, mistakes may be made and the whole building will be destroyed due to negligence or even loss of life.
Usually, steel structures are chosen for multi-storey buildings and therefore are of great importance in the building in terms of engineering. However, these skeletons can also be used in single-storey buildings. All the engineered points when designing will work with the correct installation of the steel structure, and if this is not done properly, these calculations and the result will also change. Therefore, the installation of the steel structure requires both sufficient care and knowledge and requires experience and skill.
Each steel structure is composed of different parts, which must be trained both theoretically and practically to install it. Usually, the technical and vocational organization in this field in each province of the country holds skill courses at some time of the year. In this article, we will briefly explain the important things in each field for your familiarity. The general principles of installing steel structure are based on written standards and engineering regulations for the construction of various structures, which you can also use these references.
Installation of column plate bolts in steel structure
The first and most important step for raising a building is the installation of a steel structure, and the first parts of this skeleton include column plate bolts that need to be installed precisely in their location, ox plate columns. In order for the installation of these pages to be done with high accuracy and there is no need to relocate them, mapping cameras should be used to locate them. On the other hand, bolts should be placed in their place so that when concrete is done on them, they do not move from their place and do not move. This is done easily using a special schabelone for the column plate and four bolt stabilization stands. This shablon is a plate with the same dimensions as the column plate, which is made of wooden or metal, and is used to fix bolts and accurately install the main column plate.
Another method of installing the main column plate is precisely on the foundation, which in this method a tool such as crane is needed and therefore it will take time. On the other hand, there are more administrative problems in this method and if it is not implemented carefully, you may have problems installing beams later. The last thing to keep in mind when installing bolts is that before concrete the threaded parts of each bolt should be completely impregnated with grease and closed with sacks or nylon. This makes it easy to open and close the column plate beads after concrete .
After the columns, we go to build and install beams. The construction and installation of beams directly depends on the type of connection including welding, screw or rivet, as well as whether the connections are simple or simple. When installing beams, points such as weld length, length of beams, observing beam tolerations, welding type, welding dimension, type of screws needed, electrode needed for welding and ... Full note. For the construction and installation of beams, usually one of the four methods of sliding, splice, joint and flange is chosen depending on the conditions of the project and the opinion of the employer or contractor. The easiest method among these four methods is sliding, which is more applicable in the installation of steel structure.
After the installation process of the steel structure is completed, final control should be done by the contractor and supervisory engineers. In this control, many points such as steel structure construction checklists and installation, standards required for the installation of steel structure, checking the sizes and calculations performed should be taken into account.
