Q:Steel structure brush fire retardant coating per square meter kg?
The amount of fire retardant paint is determined according to the coating thickness of fire-resistant coating, and the indoor thin steel structure fire retardant coating: the fire resistance limit of 2.5 hours per square meter is 6kg. Fire resistance limit of fire resistance limit of fire resistance limit of 2 hours per square meter was 4.5kg for 1.5 hours the amount per square meter 2.5kg 1 hours the amount per square meter 1.5kg indoor ultra-thin fireproof coating for steel structure: the fire resistance limit of fire resistance limit of fire resistance limit of 2 hours of consumption per square meter 3.5kg 1.5 hours per square meter per hour amount 2.9kg 1 the amount of 1.6kg square meters of indoor thick fire retardant coating for steel structure, fire resistance limit of 3 hours per square meter was 23kg. 2..0 hours of fire resistance per square meter dosage of 14kg
Q:Steel structure canopy belongs to the metal structure which component? Steel roof truss? Steel wall frame? Or steel grid?
1, if the structural part of the main steel structure is H steel or other profiles, that is, steel roof truss
Q:Name of steel structure awning
Polycarbonate material with high strength impact resistance is about 200 times the strength of glass. The raw materials imported from Germany and in the domestic processing, through the double co extrusion technology added anti ultraviolet material (UV), it can prevent more than 98% of the ultraviolet radiation, protect the car paint surface, can effectively control the temperature rising. It also has flame retardant effect and can be used for more than 30 years under the environment of -30 to 60 degrees Celsius (137 degrees of thermal deformation).
Q:How to calculate the steel structure quota?
Steel structure is mainly made of steel material, and it is one of the main types of building structure. The structure is made up of steel beams, steel columns and steel trusses made of shape steel and steel plate.
Q:What is the edge of the steel structure?
Water is a kind of waterproof technology in construction, popular said is actually in the wall and the roof, is at the intersection of waterproofing in all need waterproof treatment that is the facade, with waterproof material to wrap the corner. And different apron
Q:What is an engineering structure?
According to the structure of the force system, type of engineering structure are the main frame structure, shear wall structure, tube structure, tower structure, mast type structure, suspension structure and shell structure, grid structure, plate structure, wall structure, structure, structure, folding inflatable membrane structure.
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:What does the steel structure lug 2-240*290*12 mean?
The characteristics of the steel is of high strength, light weight, good integral rigidity, deformation ability, it is used in the construction of large span and super high and super heavy buildings especially suitable; homogeneous and isotropic material, an ideal elastic body, the most consistent with the basic assumption of the general engineering mechanics; material has good plasticity and toughness that can have large deformation, can well withstand dynamic loads; short construction period; the high degree of industrialization, can carry out specialized production of high mechanization degree. Steel structure of high strength steel, greatly improve the yield strength of steel rolling; in addition to the new varieties, such as H steel (also called wide flange steel) and T shaped steel and steel plate to meet the needs of a large span structure and high-rise building.
Q:Installation quota, there are tubes, steel structures and general steel structure, how to distinguish between the two?
Installation is only water and electricity installation, that is, the general steel structure. I do not know what you said is the instructions, if it is the installation of water and electricity support, then the electrical and ventilation is a set of general steel structure (general iron component production, installation), the pipe is to use pipe stent installation.
Q:Housing cost of civil steel structure
The steel structure cost is high, the service life is in 100 years or so (ordinary frame structure is 70 years)Only parts cost about 1000 yuan / square meters.As long as the regular design institute calculates the load, the constructed ones are safeThe steel structure must be of high cost and it is not allowed to build brick structures nowIn addition, there are frame brick concrete structureThe steel structure must be the most expensive
