Q:What are the connecting forms of steel structures? What are the characteristics of each?
The bolt connection can be divided into two kinds: common bolt connection and high strength bolt connection. The advantages of the bolt connection are that the construction technology is simple and the installation is convenient, and the utility model is especially suitable for installation and connection on a construction site. The disadvantage is that due to open holes on the component section, there are some clear and weak connected panels need to overlap or separate pieces and connectors. Therefore, the welding material more than. In addition, the bolt connection is required in the plate making hole, etc., and the work place is increased.
Q:What is the ultimate capacity of steel structures?
A condition in which a structure or component reaches a specified limit for normal use or durability, referred to as the serviceability limitSuch as (1) affecting the normal use or appearance of deformation;(2) local damage (including cracks) that affects normal use or durability;(3) vibration affecting normal use;(4) other specific conditions that affect normal use;
Q:What are the budgets for fire-resistant coatings for steel structures?
According to the steel structure expansion area calculation, according to time brushing number, apply the corresponding quota, modify the main material prices and labor costs, take management fees, profits, fees, taxes, summary.
Q:Measures to prevent rust in welded seam of steel structure
95% pure zinc protective film can effectively resist rust and corrosion, providing years of rust protectionBecause of the strong permeability, after the protective film has been scraped, the zinc can protect the metal from corrosionRepairing damaged metal surface is effective, used for welding seam repair.
Q:The longitudinal force of a steel column supported by a steel column
The material has good plasticity and toughness, and can have large deformation, can well withstand dynamic loads; short construction period; the high degree of industrialization, can carry out specialized production of high degree of mechanization; the processing of high precision, high efficiency, good sealing performance, so it can be used in the construction of tank, tank and transformer etc..
Q:What is the difference between rigid connection or hinge in steel structure?. Are all high strength bolts connected just now?
In fact, steel joints are generally difficult to be made of pure rigid joint or pure hinge. Likewise, different arrangement of different performance such as rigid hinged pillars generally stiffened column base, anchor bars in the bottom edge is more rigid. If the steel column base section reduced, ribbed or not and anchor bar closer to the section is more biased hinge. Whether the beam has been joined or not, the simpler way is to see if the flange is welded. If welding is partial to the line, if it is not welded, it will hinge on the hinge.
Q:I want to make light steel structure. What tools do I need?
The other also need some tools, such as hand Hu Lu, high-strength screw gun, semi-automatic cutting machine or cutting etc.Some consumables are also needed, such as wire ropes, polishing plates, etc.
Q:What kind of material test is necessary for steel structure engineering?
All materials used, such as various steel plates, steel tubes, H steel, square tubes, etc.. Purlin and color steel plate generally do not do, do bulk insulation cotton.
Q:Which is better, the fire resistance of the reinforced concrete structure and the fire resistance of the steel structure?
The steel melting point, steel structure is not to the melting point, when the burning temperature reached 500 degrees, the structure will collapse, concrete has no melting point, when the temperature reached 80 degrees will appear on the surface of concrete crack, skin peeling.
Q:How many square meters is one ton of steel structure anticorrosion?
After the reunification of 2000, the inventory valuation scheme began in 2003.Not in the national norm, local and trade quota were clear, petroleum and petrochemical quota according to their characteristics made tons of conversion of 28 square meters and 38 square meters of two conversion data is used in petroleum and petrochemical engineering
