Industrial shed is usually used to construct industrial halls from sections with variable cross-section that the dimensions and weights of these sections change according to the usage of each industrial unit. The most important factors in determining the weight of industrial halls include: the desired area for the construction of the industrial shed from the direction of wind speed, as well as the maximum amount of snowfall, the span of the hall, the height of the pillars and in case of need, the overhead crane.
The most used prefabricated steel buildings around the world are industrial sheds and is used in more than 90 percent of the industries, warehouses, stadiums, livestock and poultry production centers, etc. , and according to the dimensions of the span, height and length and bearing capacity of the region snow and wind, have various forms at the time of design. The most important consideration for economizing each order is to know the actual size of the mentioned dimensions and predict the required items.
Obviously, the best computations without considering the quality of welding, the use of bolts and nuts, and other standard joints, de-rusting and scientific coloring, or the proper application of the components, will be lacked the necessary strength and effectiveness. It needs to be explained that all manufactured parts of the company have been using a multi-year experience and constant monitoring, automatic submerged arc welding and the use of a fully standard material that can be seen at any time by the employer and has been approved by dozens of consulting firms and the monitoring device.
Design of industrial shed
Plans of execution and details and components of the product about the skeleton should be prepared separately for each contract and issued for the construction order. Technical inspection and quality control are also under the responsibility of design representatives. Design can be done by the company individuals with Safe, Etabs and Sap2000 software, or in some cases carried out by specialist or consulting firms. The executive plans of the foundations are also provided by the designers of the company and delivered to the buyer for its implementation.
According to the Schedule organization’s standard, up to 20 percent slope in Iran, the snow load is divided into four sections: 25, 90, 150 and 200 kg/m2. The majority of orders for the snow load are assumed to be 150 kg/m2. Based on the Schedule organization’s standard, the wind pressure in various regions of Iran, is displayed up to 92 kg/m2.
Types of Industrial shed
Industrial shed have different types:
- Single span as 8 Industrial shed
- Two or more spans with a common column of 88 or 888 or 8888 Industrial shed
- Double span in the form of 8 Industrial shed
- Circular Industrial shed
- Polygon Industrial shed
Appearance of the industrial shed
The shape of the metal frame can be either a simple frame or a composite, or with a middle column, or a compound middle column, or with a (single-sided) slider that the skylight can be installed for lighting in the ceiling. One side and two sides of the canopy can be installed around the hall. It is also very common in the production halls of install overhead crane.
The apparent dimensions of the industrial shed
The halls of industrial shed can be produced up to 60 meters, and usually the required spans of the halls are from 10 meters to 25 meters with a simple frame, and the average span in the industries is 20 meters and the usual height is 6 meters.
Specifications of the industrial shed components:
The main components of a prefabricated metal frame are mainly as follows:
- Wall post
- Z purlin
- Crane Beam
- Anchor rode
- Roof and Brace
- Base plate
- Crane anchor gutter or Project implementation brackets
Characteristics of the industrial shed
Industrial shed building because of its largely industrial application in terms of design is different with other structures, especially the frames are completely different in these types of structures and have slopes, and the spans are also larger than other structures. Due to the large dimensions of the beams and columns, it is not possible to use the profiles existing in the market for the construction of this structure and they should be constructed, which is called the girder.
General steps of the industrial shed building project
Construction and assembly of all metal frame structure parts perform inside the factory. The construction includes: cutting, initial assembly, initial welding, final assembly, final welding, cleaning and painting of the industrial shed and installation of metal frame structure at the desired location. In addition to the main parts made, some other parts, such as bolts and nuts, should be carried to the place, then with the help of the crane and the beam and the necessary tools installation and final adjustment take place.
