Q:What are the types of steel structures?
Structural engineering is the discipline of structural selection, mechanical analysis, design theory, construction construction technology and organization management methods, which are common in the construction of various engineering facilities. Not only refers to the object of the project construction, that is, all kinds of engineering facilities, but also refers to the applied materials, equipment and the technical activities such as survey, design, construction, maintenance and maintenance. Structural engineering is one of the two subjects of civil engineering. It occupies a very important position in the whole urban and urban construction field.
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: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 is the performance and function of steel structure engineering?
Steel structure engineering is mainly made of steel, with large span, steel structure, workshop frame, steel structure workshop, light overall, saving foundation, little material, low cost and short construction period. Safe and reliable, beautiful appearance, stable structure and other advantages. Steel structure workshop is widely used in large span industrial buildings, warehouses, cold storage, high-rise buildings, office buildings, multi-storey parking lots and houses and other construction industry.
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.
Q:The steel structure housing about how much money.
If it is a high-rise, it will need to increase the steel beam, then the cost will increase accordingly. Refer to
Q:What is a light portal steel frame?
Light steel structure is made of steel (steel plate and shaped steel), and compared with other materials, the steel structure has the following characteristics:High strength steel strength and elastic modulus of concrete, masonry and wood to be many times higher, due to the small weight, high stiffness, steel structure for the construction of large span and super high and super heavy buildings especially suitable for.Small weight - the weight of ordinary steel roof truss only reinforced concrete roof truss 1/4~1/3, if the use of thin-walled steel roof, it is lighter. Because of its light weight, the steel structure is also convenient for transportation and lifting, and can lighten the burden of the substructure and the foundation.Uniform material - the internal structure of the steel is uniform, very close to the isotropic body, and in a certain range of stress, it belongs to the ideal elastic work, and accords with the basic assumption adopted in engineering mechanics. Therefore, the calculation method of steel structure can be accurate and reliable according to the principle of mechanics.
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?
When the steel column is struck, the deformation of the plate belongs to the partial buckling of the plate:1. Flame correction;2. The transverse stiffener is arranged on both sides of the web plate of the correcting part;3, you can hit the flange, flange welding reinforcing plate;If the web is struck, the web shall be welded to the stiffener.
Q:Steel structure, tied with brace pipe casing and how the difference? What difference?
The casing is pipe, casing is roof straight brace at the oblique brace increase casing
Q:Can the steel structure workshop be used as the ground lead of lightning rod?
Second mine buildings or third mine buildings for steel or reinforced concrete buildings, between the steel or reinforced connection meet the specification and use it as a lead line under the condition when the vertical pillar plays a lead role, can not meet the requirements of special spacing between deflectors the.
