Construction of metal skeleton frame
The frame of steel structures, which includes stainless steel structure framing, describes the construction of a metal skeleton frame which consisting of vertical columns and horizontal beams. This skeleton supports the ceiling, floor and wall of the structure. There are three main types of structural steel systems. They have frame structure rigid, modular frame and single slope frame. Selecting the type of a steel frame to use a particular project requires an examination of a number of factors, including the width of the building, height, location, type of roof and the use of the building.
Definition of construction of metal skeleton frame:
The construction method of high-rise buildings, in which the main horizontal and vertical members are rolled steel, and most of the walls on the floor are supported by their steel frame.
Construction steps of foundation for metal skeleton frame buildings (bolted metal skeleton):
Performance Tips for foundation infrastructure:
The basic stages of the metal structure include the construction of a suitable foundation that executes roughly the same on all projects, but before a brief description of the construction of the foundation, it should be noted that at first the plan of landing has been implemented on the ground, and for the accurately implementation, it has been needed to be determined required details in the plan. The structure is divided into a network of perpendicular axes, and the position of the above-mentioned axes is determined relative to the axes or defined points, such as the axis of the road on the ground, on the adjacent building, etc.
(Usually the axes of an extension are numbered with numbers of 1, 2, 3, etc. and the other direction axes are marked with the letters A-B-C, etc. It should also be noted that the columns and foundations that have the same status in terms of load are shown with the same marked: the column with the letter C and the foundation is indicated by the letter F. Drawings of the sections and writing the digits under the foundation, the digits on the foundation, the height of the parts of the foundation, the lean concrete specifications, the concrete specifications, the type and the overall diameter which is required for cutting the bars, should be indicated on the plan.
Before laying the plan on the ground if the ground is uneven or contains plants and trees, the unbalanced highlands should be removed and the area should be cleared of all the plants and roots. Then the north geographic of map will match the plan of the north of the geographical area where the project is to be executed (this is called map justification) after this, we will implement one of the axes (the longitudinal or transverse axis) which is marked on the plan, on the ground, with at least two nails at the beginning and the end, which is said to be along the base axis
Now we identify other longitudinal and transverse axes on the base axis (by wooden or metal nails on the ground) with a theodolite camera and for small-rooted works it executes on plumb rule, meter, rule and plumb bob. Now, if we want to excavate the site, we need excavation height, that even if the ground has a slight elevation, the point as the base (B.M) should be determined in the workshop area (this point is creating by concrete and bar at a point far from damage).
Technical and executive issues related to excavation: having basic information on ground and type of soil such as: soil compression strength, especially for degradability, groundwater status, glacial depth and other physical properties of the soil that are determined by testing the soil from that site, is very necessary. In foundation excavation, while execute in the underground, the wall may fall or underneath the adjacent drainage may be lost, with a variety of tools, the pavement and protection of the wall should be made; so that it has sufficient resistance to the loads it has. One of the solutions to prevent the fall Soil and foundation of adjacent buildings, is differential implementation which first executes at the location of the foundation of the columns, and at the next step, after the gradual excavation, other components of the wall are carried out. Bolted metal skeleton frame
The Hadid Karan Company has over a decade of activity in the field of production and manufacturing steel structures, metal skeleton frame, bolted metal skeleton frame, execution of metal structures, construction of metal skeleton frame, bolted metal structures, steel skeleton frame and design and construction industrial shed.
