Q:What does the title of a steel structure mean?
A truss is a structure in which the bars are hinged with each other at both ends. The straight rod truss has a generally triangular unit plane or space truss structure, mainly bear axial tension or stress, which can make full use of the strength of materials, the span is large than the solid web beam to save materials, reduce the weight and increase the stiffness. In the membrane structure building, truss design is very important, or it can support the whole building.
Q:What is steel structure steel plate?
The penetration welding spot welding, welding should be prepared before the arc welding test pieces, adjust the welding current. Because the floor plate at the bottom of horizontal and vertical supporting formwork, pouring concrete material should not be too concentrated, the plate vibrator timely allocation of vibration.
Q:What does the name below the steel structure of the pillars of the corner piece of iron bolt connection called ah
Steel column base, usually has two connections, and a lower anchor bolt, according to the column size, set 2, 4, 6 or more pieces of anchor bolts, no embedded parts (that is, in the above concrete plate), installation of steel column, a regulating nut is arranged in the column bottom plate anchor bolt, steel column base plate column falls directly on the adjusting nut, the flatness of the steel column to adjust the adjusting nut.
Q:What kind of material test is necessary for steel structure engineering?
The test of high strength bolt connection must be done, and the anchor bolt needs to be made of raw material.
Q:What is the two steel structure?
It is in the range of a structure (referring to the main structure of the bearing component part) after the completion of construction construction, is relative to the supporting structure, non bearing structure, the steel structure of the retaining structure, such as structural column, beam and lintel, waterproof anti parapet, filling, capping, partition wall steel structure the.
Q:Steel structure workshop and equipment have static electricity is how?
Steel structure plant and equipment rarely appear static savings phenomenon, this is because the steel structure and equipment are connected to the shell, and the metal is a good conductor, static steel structure ought to be able to pass into the ground.
Q:In the installation of steel structure, insulation foil should be placed in the side wall or side wall? Why?
This is not strictly required, generally in the installation of steel structure workshop enclosure plate, insulation foil should be in the inner side of the wall.
Q:Ratio of width to thickness in steel structure design,
Slenderness ratio refers to the bar length and the member sections turning radius ratio, note that is calculated length bar, and calculate the length of rod end of the connection, such as fixed, hinged, links, freedom, slenderness ratio is not long and short side ratio. The turning radius is a material mechanics concept, the complexity of the computation.Slenderness ratio refers to the bar length and the member sections turning radius ratio, note that is calculated length bar, and calculate the length of rod end of the connection, such as fixed, hinged, links, freedom, slenderness ratio is not long and short side ratio.
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:What does HN350*175*7*11*16 represent in steel structures?
HN350*175*7*11*16 in steel structure: H steel, 350mm high, 175mm wide, web thick 11mm, upper and lower plate thickness 16mm.
