The present invention is by orthogonal-diagonal lattice formula steel weir on an empty stomachThe orthogonal-diagonal lattice multilayer that made obtains that is connected of lattice superstructure and orthogonal spatial formula steel grid wall frameThe building structure of Steel Space grid boxlike, makes the orthogonal both direction of steel laced beam stressed evenly, fromAnd make both direction member shared floow load, can reach so effective reduction steel using amountEffect. Technical scheme proposed by the invention is actual is a kind of assembled integral Steel Space gridThe new system of orthogonal-diagonal lattice superstructure box structure. Proposition of the present invention is according to Long-span Multi-storey Frame degree workThe feature of industry workshop form determines. Due to industrial plant plane be generally long narrow rectangle (asShown in Fig. 1), its long (being longitudinal length lx) is logical with the length-width-ratio of wide (being span ly)Normal is lx/ly=4. If industrial plant is span ly=18m, its longitudinal length lx=4ly=72m,If make the waffle floor (as shown in Figure 2) of the orthogonal spatial of traditional approach, at superstructure justWhen the external force action P=1 of central authorities, it along lx to the external load distributing is: px=p/n is short along lyTo Distributing loads Py=p-p/n, in the time of n=4, the load distributing along span (ly) beam is:py=3p/4, from then on can find out that its space-load is extremely inhomogeneous significantly. Unidirectional as reinforced concretePlate is the same, along short (ly) arrangement of reinforcement by calculative determination, along long true by constructing to (lx) arrangement of reinforcementFixed, as shown in Figure 2. When superstructure both sides span equates, i.e. lx=ly, flooring central authorities loadDistribute both direction load Px=Py=0.5P, i.e. the orthogonal spatial grid type building of square-shaped planarCover stressed evenly (as shown in Figure 3). When being rectangle plane (as shown in Figure 2), and lx/ly >=n(n=2,3 ... 8), time, should arrange orthogonal-diagonal lattice by Steel Space grid hollow floor system of the present inventionGrid, as 45 ° of angle dotted line positions in Fig. 2, floow load P acts on 45 ° of angle skiesWhen web grider (in Fig. 2, dotted line represents) both direction, also can accomplish Px=Py=0.5P. From thisIn just can find out significantly, for the building structure of rectangle plane (be lx/ly >=n,N=2,3 ... 8), as adopt orthogonal-diagonal lattice formula steel laced beam grid superstructure of the present invention and just orthogonalPut the orthogonal-diagonal lattice multilayer Steel Space grid boxlike building structure that formula steel grid wall frame connects to form,Its distribution of force along lx and ly direction is just very even, and the uniform effect of its distribution of force canReach the stressed effect of square-shaped planar. Therefore, adopt the present invention to reach significantly and reduce useThe object of steel amount.
For example, for span ly=4000, the simple supported edge board of lx=8000, its thickness of slabH=140mm (l/28.6), one-way slabs reinforcement manner routinely carries out arrangement of reinforcement, along short (ly)Levels arrangement of reinforcement, needs every square metre of steel bar stress 10.17kg, needs every square along long to (lx)Rice reinforcing bar 2.4kg, adds up to 12.57kg/m2; When concrete board plane is of a size of square (4m × 4m),Floow load is born (q/2) by the steel bar stress of both direction, two-way slab side that can be routinelyFormula is carried out arrangement of reinforcement, and both direction levels arrangement of reinforcement is all the same, adds up to 8kg/m2; These two kindsEvery square metre of quantity of reinforcement differs 12.57-8=4.57kg/m2, one-way slabs quantity of reinforcement compares two-way slabQuantity of reinforcement increases more than 35%. From unidirectional and two-way concrete slab arrangement of reinforcement, the sky of two-way slabBetween the three-dimensional stressed one-way slabs that is greatly better than, by parity of reasoning, when the plane of industrial premises superstructure is squareShape, and its lx/ly=n (n=2,3,4 ... 8), time, if adopt conventional steel frame, work as ly=18mTime, q=5kN/m2Steel using amount is 122.5kg/m2, be 201110437708.5 when adopting application numberThe technical side of disclosed " assembled integral orthogonal spatial hollow sandwich panel ceiling for storied building box structure "When case, its steel using amount is 86kg/m2; And while adopting technical scheme proposed by the invention, itsSteel using amount is only 72.5kg/m2, this is than the multilayer of conventional steel-frame structure (three layers) large span(ly=18m) industrial premises steel using amount (122.5kg/m2) declining more than 40% (declines50kg/m2). So compared with prior art, the present invention not only has can be effective in the present inventionReduce the advantage of steel using amount, but also have simple in structure, make easily, construction costs is low,Construct time saving and energy saving, reliable construction quality, the advantage such as structural strength is high, structural stability is good.
