2. Our building systems description

Our industral shed is an pre-engineered steel structure which is formed by the main steel framework linking up H section, Z section, and Csection steel components, roof and walls using a variety of panels. The steel workshop building is widely used for the large-scale workshop, warehouse, office building, steel shed, aircraft hangar etc.

Q:The role of stiffeners in steel structures?
In the process of structure design, the structure may be suspended to span is too large, or too large, in this case, the connection structure can bear the load, the common vertical in the two combination on a reinforcing plate, reinforcing ribs (commonly known as JIN in reading the project, in order to increase the strength of binding).
Q:What is the fire-resistant time of steel column under steel structure?
In order to make the steel structure materials overcome the shortage of fire protection in practical application, fire prevention must be carried out, the purpose of which is to raise the fire resistance limit of the steel structure to the limit range prescribed by the design specification. To prevent the deformation of steel structure in heating in the fire quickly, the measure is varied, the key is to adopt different methods according to different situations, such as the use of thermal insulation and refractory material directly blocking flame burning steel structure, reduce the heat transfer rate of temperature rise, steel structure to postpone the weakening time. But whatever the method, the principle is the same. Here are some different steel structure fire protection measures.
Q:Steel structure component assembling method
Vertical mounting: according to the characteristics of components and the stable position of parts, choose the top-down or bottom-up assembly. The method is applicable to a structure with a smooth and small height or a large diameter cylinder.
Q:How to determine the thickness of anticorrosive paint for steel structure?
When the design does not require the coating thickness, the total thickness of the coating should be 150 m, and the room shall be 125 m, the allowable deviation is -25 mu m. The allowable deviation of the dry paint film thickness per time is -5 mu m." Check quantity: according to the number of components, check 10%, and similar components should not be less than 3 pieces.
Q:How long is the fire resistance rating of steel structure two?
As everyone knows, the steel structure is usually at 450 DEG C to 650 DEG C temperature will lose the bearing capacity, big deformation, resulting in steel column and beam bending, the results caused by excessive deformation can't continue to use, generally without steel structure fireproof limit protection for 15 minutes.
Q:What is the two steel structure?
Two definition: in the steel structure frame, shear wall, frame some non bearing masonry, shear in engineering structural column, some need to be completed in the lintel decoration before the steel structure, known as the two steel structure.
Q:What is steel structure steel plate?
When the length of the material is controlled from 3 to 6m, the problem that the vertical transportation can not be suspended between the secondary beams can be avoided. When the floor slab is hoisted, a special soft sling is used. Check the soft sling for tearing and cutting when lifting. When the support plate is used on the steel beam, the probe shall be prevented. When laying, the operator shall wear a seat belt and ensure that the edges are secured to the perimeter safety rope.
Q:What are the differences between steel structures and concrete structures?
Generally speaking, the steel structure is more energy saving, environmental friendly, high strength, good seismic resistance, fast construction speed and suitable for industrial production. The reinforced concrete structure corrosion performance is good, good insulation effect.
Q:The position of the steel structure requires a spring cushion for mounting the bolt
Ordinary bolts: the bolts must be tightened so as to prevent the bolts from loosening. A spring washer prevents looseness between the connecting plate and the nut. When the nut is preloaded, the gasket is flattened to produce an elastic reaction force that forces the screw between the threads to increase friction and prevent looseness. However, due to uneven elasticity, the shock loading during operation results in poor looseness of the gasket. Generally used in less important connections.
Q:In the steel structure, those belong to the main steel structure, and those belong to the secondary steel structure
The main steel member is the load-bearing member! It is the steel frame, steel columns, purlins, while those belonging to, in order to reinforce the enclosure, the steel structure is a steel member!
