Multi-Span Heavy Industrial Plant Design Research

This article studies on the north a heavy group new joint workshop for sevencontinuous span industrial workshop, single building area of110000m2, thelongitudinal length of408m, width of257m transverse, plant north of double spandouble crane, five southern cross for single crane, and the crane tonnage, variety, plantof each span crane maximum lifting tonnage from100t to800t, involving a total ofsix lifting tonnage, two of the biggest800t crane with lifting capacity of1600t; at thesame time crane rail is high, single crane rail high18m, double crane upper crane railhigh28m, high eaves height reaches38m joint plant. So the size of the plant in thedomestic and foreign equipment manufacturing industry factories in relatively few.Therefore, the joint workshop regardless of a total construction area of index, totallength, width, plant high index and maximum tonnage crane lifting and otherindicators rank in the forefront of the industry, has the very strong industryrepresentative.In this paper seven connected across the column size, heavy-duty industrialworkshop of bent frame column forms are multiple schemes research on thecalculation of integrated cost, to use as evaluation standard, optimize the economicand reasonable structural arrangement and structure system.Research shows that: the building space size is decided to plant overall amount ofsteel are important factors; steel structure industrial building the steel structure systemcan be divided into industrial longitudinal spacing on sensitive component system andnon sensitive component system; the bent frame column of heavy steel structureworkshop steel quantity in the largest proportion of the system, followed by the cranesystem, roof system, intercolumnar supports, bracing system; able to cross heavyindustrial plants,18m column and12m column schemes, the comprehensive cost of2500000yuan can be saved; the same workshop space and structure, concrete filledsteel tubular lattice column than the steel lattice column scheme can save nearly40%of steel consumption, save integrated building materials cost more than30%; forseven continuous span industrial workshop, the first double column grid structurecolumn approach, effectively solves the multiple connected cross plant horizontalwidth, temperature setting expansion joint and waste plant space problem. Doublecolumn grid structure column approach with the traditional approach compared withdouble columns, steel saving consumption of around50%, and the steel columncovers an area of reduced amounts to20%, comprehensive effect is prominent;through the finite element calculation result analysis, get in the lattice columnshoulder beam design, should be appropriate to increase web thickNess or reasonablearranging stiffeners, and appropriately increase the web and column flange platebetween the strength of welding seam. Combined with practical engineering research, solves the continuous spanindustrial workshop design problem, for the practical engineering design providedtechnical basis, effectively saves the project investment, obtain the conclusion andsuggestion for future multiple connected cross heavy-duty industrial workshop designprovides important reference value.
