What is steel warehouse building?

​

Steel warehouse building is composed of steel material structure, is one of the main building structure types.Structure is mainly made of steel and steel plate, steel column, steel truss girder artifacts, such as weld is required between each components or parts, bolt, or rivet connection.Because of its weight is lighter, and the construction is simple, widely used in large factories, stadiums, high-rise, and other fields.

The characteristics of steel warehouse building:

Steel is characterized by high strength, light weight, good overall stiffness and deformation ability, therefore, to build large span and super high, super-heavy buildings is suitable;Homogeneous and isotropic materials is good, is a ideal elastic body, the most in line with the general engineering mechanics basic assumption;Material plasticity and toughness, good can have large deformation, can bear dynamic load;Short construction period;Its high degree of industrialization, high mechanization degree of specialization of production can be performed. Steel structure components are easy to manufacture, site assembly in the factory.Mechanization of factory manufacture steel structure component products of high precision, high efficiency, site assembly speed up, short time limit for a project.Steel structure is one of the most industrialized structure.

Steel structure fireproof performance
When the temperature was below 150 ℃, the steel properties changed little.Thus the steel structure is suitable for the hot shop, but the structure surface at the thermal radiation of about 150 ℃, to adopt heat insulation board to protect it.Temperature at 300 ℃ to 400 ℃. The steel strength and elastic modulus were decreased significantly, the temperature about 600 ℃, the steel strength tends to zero.In buildings with special fire protection demand, steel structure must be preserved with refractory materials in order to improve the fire resistance rating.

The application of steel structure
Steel structure is widely used in residential, factory, warehouse, tower, power plants, Bridges, and other areas of the building.Steel structure industry is usually divided into light steel structure, high-rise steel structure, steel structure residential steel structure, space and bridge steel structure of the five subclasse.

The Leiting Heavy steel structure workshop - metallurgical automatic transmission equipment assembly base steel structure project. Located in Qingdao China High-tech Zone, total span is 120 meters, total length is 198.1 meters; eave height is 13.2 meters; the ridge height is 18.6 meters.

Specification of steel structure workshop
The workshop steel column is lattice without anchor bolt that has a strict requirement for the steel column’s perpendicularity, elevation and axis deviation. The column bracing, welded by channel steel and angel steel, is double layer installation. Roof horizontal bracing is continuous connection by angel steel; the middle column crane beam is divided into two layers. All crane beams are installed walkway plate and guardrail and each walkway plate has two ladders and escalators. The wall panel use v-780 type wave board; the wall between the upper and the lower window is the horizontal installation, the upper window is skylight plate, therefore the wall installation must be vertical to avoid clearance.

Steel structure workshop installation quality control

1) before installation, the construction unit of product certification, design documents and deal with members assembled records for inspection, record the size of the component and the reinspection do not coincide.Deformation of steel structure, defects exceed the allowable deviation, should be handled.
Before the installation, should prepare a detailed measurement and correction of the process, the welding of thick steel plate shall be installed in the welding process test of simulated product structure before, prepare the corresponding construction technology.Wriggle through the earth to assemble good roof should be preset a certain degree.

(2) steel structure hoisting in place, after dealing with components such as design requirements for control point positioning axis, elevation measurement marking, for lifting the butt joint quality inspection before welding.Temporary support wave and steel cable is installed in order to make the security and stability of steel roof in construction process.

(3) the steel structure installation, the construction unit shall submit each common component after lifting the elevation dimension, welding, painting and so on were submitted to supervision of acceptance.

The total steel structure building price was $5.38 million USD,the steel was about 2600ton,the whole contract period of 150 days,80 days on-site installation and construction of 80 days.It is used as gold mining plant.

Steel column:latticed column,with the height of the latticed column up to 39 meters,fixing the column foot adopts shape of rim of a cup foundation,with buried depth of 2.2 meters,and single steel column weighing about 28 tons,a total of 22

Steel beam: tube truss steel structure,span 33 meters,12 meters bay,33m main span on each side of 17.445 and 14.26m auxiliary span, auxiliary span for two or three layer structure,

Five storeys platform in the main span.And among messy distribution of platform steel column are criss-cross with civil foundation.

This prefabricated Food Processing Plant building used for oil refinery was finished in 2010, it is 3 floors and some parts is 5 floors.and all internal design was built as per customer’s request.There is a little such this kind of building in steel structure line.

Steel structure building data for reference:

The reasonable application of prefabricated steel structure building

1, heavy duty industrial workshop, span and column spacing is larger Or with the heavy duty crane or large tonnage crane or hoist with 2 ~ 3 layers of factories and some high temperature workshop Appropriate USES steel crane beam steel roof truss and steel column and all steel structure components
2, the structure of the long-span structure: the larger span Reduce the structure weight has obvious economic effect
3, tall structures and high-rise buildings, tall structures including substation high-voltage transmission line tower architecture radio and television launch tower and mast, etc These major structure under wind load in addition to the light weight steel structure Ease of installation construction Also because of the light weight, high strength of steel Small component section reduced the wind load To achieve more economic benefits
4, subjected to dynamic loading structure: due to the good dynamic performance of steel Good toughness Can be used as a direct bear up the weight or larger span larger bridge crane crane beam
5, removable and mobile structure: flow type gallery and prefabricated houses, etc The most appropriate USES light weight steel structure steel structure To facilitate the demolition Using bolt connection And convenient for assembly and disassembly Construction machinery in order to reduce the structure weight Steel structure must be adopted
