Steel Structure:

1.The steel structure of the connection method: welding connection
2.Steel structure design common norms are as follows: "Steel Design Code" (GB50017-2003) Cold formed steel structure technical specifications" (GB500182002) "Construction Quality Acceptance of Steel" (GB50205-2001) "Technical Specification for welded steel structure" (JGJ812002, J218 2002) "Technical Specification for Steel Structures of Tall Buildings" (JGJ99-98)
3.The characteristics of steel Light weight steel structure Higher reliability of steel work Steel anti-vibration (earthquake), impact and good Steel structure for a higher degree of industrialization Steel can be assembled quickly and accurately Large steel interior space Likely to cause sealing structure Steel corrosive Poor fire-resistant steel Recyclable steel shorter duration.
4.Commonly used steel grades and performance of steel Carbon
structural steel: Q195, Q215, Q235, Q255, Q275, etc.
High-strength low alloy structural steel Quality carbon structural steel and alloy structural steel Special purpose steel Product Feature Carport, House, Office, Shop, Toilet, Villa, Warehouse, Workshop, Plant Other Information.

Q:Is the floor of the steel structure slab cast-in-place or steel?
The steel floor of the steel structure building is steel.
Q:What are the budgets for fire-resistant coatings for steel structures?
Fire resistance grade 2.5 hours, paint should be painted to 3mm. General again brush up 1.3mm thick and material price in Xi'an area with artificial material does not contain measures fee at 55 yuan / square meters of brush, but not regular professional fire, professional fire can meet the design requirements with the price will be twice as expensive as about 100 yuan.
Q:Why are the main and main beam joints of steel structures articulated?
The hinged construction is convenient, the requirements of the secondary beam are large, the maximum bending moment is in the midspan, and the torsion resistance of the rigid beam is high.
Q:What is the cushion block in the steel structure?
In the steel structure of wedge type block is used to adjust the steel structure column or large equipment and the top surface of the base pad installed with the steel quantity.
Q:What are the advantages of steel structure houses?
The characteristics of steel structure basically adopts the triangular truss system made of cold-formed steel, light steel members in sealed end structural plate and plaster board, formed a very strong - plate structure system, this system has stronger ability of resisting earthquake and horizontal load, suitable for the seismic intensity of 8 degrees above the area.Wind resistance: the steel structure is light in weight, high in strength, good in overall rigidity and strong in deformation. The weight of the building is only 1/5 of the brick concrete structure. It can withstand the hurricane of 70 meters per second, so that the life and property can be effectively protected.Durability: light steel structure residential cold-formed thin-walled steel structure using all system components, steel using super anticorrosion high strength cold rolled galvanized sheet manufacturing, effectively avoid the influence of the steel in the construction and use of the process of corrosion, increase the service life of steel member, the structure of a life span of 100 years.Thermal insulation: the heat preservation and heat insulation material is mainly made of glass fiber and cotton, and has good heat insulation effect. The utility model relates to an outer wall heat insulation board, which effectively avoids the cold bridge phenomenon of the wall, and achieves better heat preservation effect. 100mm around R15 thick cotton insulation, heat resistance equivalent to 1m thick brick wall.
Q:Excuse me, how to steel structure materials such as ah, how do I know purlin, bar, etc. What material is tied ah
Purlin, bar, etc. belong to time is tied to steel, angle steel, pipe, steel and other steel materials two processing, offer the actual weight per ton price, you have to feed the decomposition of various types of steel, (for example, the middle part is tied round pipe, both ends of steel plate, are calculated respectively after the total weight is single, tied)Most of the steel members are calculated in tons, and the wall panels are calculated by square meters. The folding parts are calculated by meters. All kinds of connecting bolts are included in the actual quantities, and the self tapping screws are taken together according to the panel area
Q:Want to ask the steel structure workshop leakage, how to do? How do you do it?
In a heavy rain, on-site inspection records Water Leakage position, if the conditions can be used to view Water Leakage close status of elevator, combined with house design drawings, a detailed record of the status of Water Leakage; to stay outside after the rain stopped, the area near the roof on the view point of the situation, meet all kinds of defect parts, should be promptly recorded, also available camera file.
Q:Is the metal structure the same as the steel structure?
The metal structure is a general term, including the steel structure, aluminum alloy structure, etc.. Somewhere, the steel structure is confined to the structure made of steel. In the past, aluminum alloy structures were seldom used, and the metal structures were basically equal to steel structures. Now, the aluminum alloy structural design code has been promulgated and implemented, the aircraft also use titanium alloy structure, metal structure of the scope is more extensive.
Q:What can be painted on the surface of steel structure to prevent rust and corrosion?
Steel structure workshop: epoxy anticorrosive primer primer, intermediate paint epoxy micaceous iron oxide intermediate coating, fluorocarbon paint is above several matching scheme is one of the most common facilities, according to the different environment different anti-corrosion paint such as high-rise building steel structure, tower steel structure and so on, if not anticorrosive paint generally used in corrosion environment for epoxy zinc yellow / iron red primer, epoxy coal tar paint, such as in the harsh environment of the steel structure, generally used in the majority of zinc rich epoxy primer.
Q:Can the steel structure workshop be used as the ground lead of lightning rod?
The building of the steel beam, steel column, ladder and other metal components and metal curtain wall column should be taken as the lead line, but between the various parts shall be connected through electrical, the copper zinc alloy welding, welding, crimping crimping, sewing, screw or bolt connection; the cross section should be according to the specification in table 5.2.1 the specified value; each metal component can be coated with an insulating material.
