Q:What is the roof of a steel structure?
Slope roofing structure of the house generally refers to the normal slope of the drainage, less than a certain standard range, it will form water accumulation, and increase the burden on housing.
Q:Are there many knowledge of structural mechanics in steel structure? What about material mechanics?
In general do not understand the theory of mechanics, material mechanics, structural mechanics, steel structure is unlikely to understand.
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 is the difference between steel structure HN and HW?
Distinction: H type steel is welded, HM, HN and HW are hot rolledHW is a wide flange of H steel, H steel and the height of the flange width is basically the same, mainly used in steel frame structure of steel column, also known as reinforced steel columns in the steel structure is mainly used for the column.
Q:How to repair the steel structure workshop H steel column in the ground 1 meters high is hit by the car deformation, in the condition of not changing the column, how to restore and ensure structural load-bearing role?
Can be directly welded steel plate for reinforcement
Q:Steel structure lateral inspection "z15" what does that mean?
In general, thick steel plate is easy to produce lamellar tearing, because the thicker the steel plate, the more non-metallic inclusion defects, and the thicker the weld, the greater the welding stress and deformation. To solve this problem, it is better to use Z to steel. This kind of steel plate is on the basis of a certain structural steel (called parent steel). After special treatment and processing, the content of sulfur is less than 1/5 of the general steel, and the shrinkage of the section is more than 15%. The mechanical properties of steel plates in the thickness direction (mainly ductility) are called Z properties. The Z properties of steel plates can be obtained by tensile tests of specimens, usually measured by cross-sectional shrinkage. China's production of Z steel plate to mark is in the parent class followed by Z to steel steel plate Z15, Z25, Z35 grade mark, the number after the Z word for section shrinkage index (%).
Q:Steel structure, tied with brace pipe casing and how the difference? What difference?
The tie bar is a fixed connecting rod between the steel beams. The drawing is generally expressed as "XG" or "GXG", and the steel pipe is usually 114 in diameter,Brace is fixed between the purlin connecting rod, a straight and inclined brace brace, drawing on the general expression of ZLT, XLT, diameter of 12 bar for general use,The main casing support, support, drawing on the general expression of CG, up to 12 bar up to + 32x2.0 circular tube
Q:Which engineering structures are more economical and rational with steel structure?
Steel structure is suitable for large span structures, such as industrial buildings;
Q:What kind of building materials are used in steel structure engineering?
Secondary frame, shear key (column bottom), purlin (walls, roof), daughter column (the wall) and canopy (wall), gutter (walls, roof), steel tile (walls, roof and so on).
Q:Construction technology practice of steel structure in interior decoration
And around the ring beam and wall with embedded parts / expansion bolt welding, filling gaps with polystyrene board insulation, achieve sound effects, and then use the blockboard or pine board tile can be integrated. Can also be added according to the needs of barbed wire, light weight ceramsite concrete pouring a layer of 40-60mm (heat preservation, sound insulation effect better). Then lay the composite floor. A gypsum slab ceiling is required below the steel structure. Suggest going to the construction site to have a look.
