Q:What are the connecting forms of steel structures? What are the characteristics of each?
Is the end of the rivet connection with prefabricated nail head rivet, screw holes are inserted in the connecting member, the rivet gun or pressure riveting machine, the other end is pressed into the closed nail head. So that the connecting piece is connected to form solid rivet clamping. Rivet connection is characterized by reliable power transmission, good plasticity and toughness, easy to check and ensure the quality of plate, can be used under dynamic structure of heavy load, but its structure is complicated, cost of steel work, poor working conditions, high cost, has been rarely used.
Q:Why steel structure is adopted in super high-rise buildings?
The steel strength (tensile and compressive) than concrete, steel (standard) 345Mpa (pull) above, 200Mpa (pressure), and concrete (standard) 10Mpa (pull), 100Mpa (pressure), so don't need stupid thick section.
Q:What documents do steel installers need to have?
Steel structure installation work requirements: structure; material, surface roughness, tolerances, surface treatment, straightness (or arc) connection; hole deviation, bolt grade; welding method, welding standard, welding materials; tightness requirements
Q:What does "CHS44*12" mean in steel structures?
The structure is mainly composed of steel beams and steel plates, such as steel beams, steel columns, steel trusses and so on. Each component or component is usually connected with welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise and other fields.
Q:How to consider the influence of base displacement on steel structure
A variety of raw materials will exist in a variety of deformation, steel structure in prefabricated projects will appear in a variety of geometric size deviation. Such as bending, uneven and non vertical and so on need to be corrected, correction works often use heating correction, the correction of the components will appear heating zone embrittlement of the scene. Material cutting or welding deformation often happen, such as a variety of complex twists and turns, distortion and warping deformation etc..
Q:In the steel structure of steel purlin 160*60*20*2.5 is what mean
Channel steel is a strip of steel with a cross section. Section steel with groove shape.
Q:What are the raw materials of steel structure?
Support: round steel, steel pipe, welded pipe, bushing, angle steel, etc..
Q:How to calculate the allowable slenderness ratio of steel structures under compression?
It can be seen from the formula that the concept of slenderness ratio takes into account the end constraint of the component, the length of the component itself and the section characteristics of the component.The effect of slenderness ratio on the stability calculation of compressive members is obvious, because the larger the slenderness ratio is, the more easily it is unstable. Here are some formulas for calculating axial and flexural members. There are parameters related to slenderness ratio.
Q:The role of stiffeners in steel structures?
Because the product can overcome the wall thickness from the difference of stress caused by the uneven deformation of the products.
Q:Which engineering structures are more economical and rational with steel structure?
Steel structure is suitable for large span structures, such as industrial buildings;
