Large-span hillside top formula steel construction storage warehouse

Technical Field

The utility model belongs to the building field relates to a large-scale steel construction building, in particular to large-span pitched roof formula steel construction storage warehouse.

Background

Facilities such as large-scale plants and warehouses are generally constructed by selecting steel structure buildings. The steel structure building has high structural strength and good structural stability. Most frame structures of the steel structure building can be prefabricated and formed in a factory and then assembled and constructed on site, construction speed is high, and construction period is short. For storage type steel structure buildings, the occupied area is large usually, and the number of the supporting columns in the building is small, so that a proper truss supporting structure needs to be designed to ensure the structural safety. For the storage facilities of the steel structure building, an arc roof or a sloping roof is generally adopted to ensure the stable structure, and particularly for the large-span steel structure building, the mechanism design of the truss support is particularly important.

Preferably, the hoisting platform is of a horizontal truss structure, the hoisting platform is arranged at one third to two fifths of the upper portion of the herringbone roof main truss, the hoisting platform is provided with an upper chord and a lower chord, and a web member is arranged between the upper chord and the lower chord.

Preferably, the turning parts of the wall surface main truss and the roof surface main truss are provided with diagonal braces.

Preferably, the diagonal tie bars are continuously arranged between wall surface main trusses and roof surface main trusses of adjacent main trusses every several trusses. The adjacent main trusses are mutually connected through the matching of the tie bars and the secondary trusses, and the stability of the structure is ensured.

Preferably, the cross section of the main truss is of a triangular structure and comprises two upper chords and a lower chord, and web members are uniformly arranged between the upper chords and the lower chord.

Preferably, reinforced concrete foundations are poured between the adjacent wall surface main trusses at the part below the ground level, brick walls are built at the part above the ground level, and galvanized steel plates are laid between the adjacent roof surface main trusses.

Preferably, a reinforced concrete foundation is poured below the ground level below the gable truss, and a brick wall is built above the ground level or a steel plate galvanized wall is adopted to build a wall surface.

Preferably, the main trusses are uniformly arranged at intervals of 5-10 meters along the length direction of the warehouse.

The utility model discloses steel construction storage warehouse span is big, stable in structure, and construction period is short, for the reserve space of accessible large-span in the warehouse, especially is fit for the storage that bulk cargo such as coal stacked.
