It is welded and fixed on the right side of shoulder beam, by roof leg 7, upper strata crane load and roof load is delivered to lower floor's shoulder beam；Lower floor's shoulder
The levels crane load and roof load that bear are passed to mid-span four limbs lattice column by beam again.
In practical application, interior limb post 8 and roof leg 7 it is Height Adjustable, and then adjust the height of upper strata crane 3.Upper strata
The end of crane girder 5 is additionally provided with upper strata crane braking system 10；The end of lower floor's crane girder 6 is additionally provided with lower floor's crane braking
System 11.
Mid-span four limbs lattice column 9 can use following structure type：Including be arranged at corner etc. height post limb, adjacent pillars
Batten plate is set between limb；In the top surface of post limb, abacus is set.
In addition, to improve the support force of mid-span four limbs lattice column 9, mid-span four limbs lattice column can be connected by shaped steel with batten plate
The combination cylinder connect, shaped steel are the angle steel formed with steel plate rolling, and it subtracts than the angle steel of the dual-layer welding of same thickness
Room, no welding deformation and the rigidity that ensure that angle steel are overlapped less；Stake holes is dug on ground, the concrete perfusion base in post holes
Plinth, the bottom of shaped steel is drilled into the inside of concrete foundation, and finally pours, and the bottom of shaped steel is firmly tied with concrete foundation
Close, improve the support strength of shaped steel.Batten plate part includes moment reinforcement；Moment reinforcement is connected between adjacent shaped steel, is used
Moment reinforcement is as the benefit of batten plate：Lattice column can be made when bearing horizontal force, there is enough bearing capacitys and resistance to become
Shape ability, the deformation by sewing part reaches good lateral resisting energy consumption effect, while steel using amount is reduced, and building cost reduces.
As can be seen here, one kind provided by the utility model is used for high-end equipment manufacturing workshop center pillar upper support bilayer crane
The primary structure member of beam, by two stiffness layers, greatly horizontal shoulder beam, inner prop limb and roof leg collectively constitute, and its operation principle is：On
Lower two layers of crane girder can be placed directly in the top surface of every layer of shoulder beam, and roof leg directly bears roof system load, and roof system load is straight
Connect and be transferred to four limbs lattice column；Upper strata shoulder beam mainly undertakes upper strata crane load.Lower floor's shoulder beam mainly undertakes lower floor's crane load
And the roof load that roof leg transmission comes, suitable for the high-end equipment manufacturing workshop of double-deck super-tonnage crane, both sides are risen
Hanging object can be lifted by crane simultaneously by double-deck shoulder beam, and played hanging object and do not limited by locus, can solve the problem that overweight object is adding
Work and the lifting problem in manufacturing process；Wherein, the lifting capacity of upper strata crane can according to interior limb away from size and lower floor's shoulder beam
Rigidity be adjusted.
Mid-span four limbs lattice column bilayer shoulder beam has advantages below compared with traditional individual layer crane+bracket of encorbelmenting construction：
(1) compared with traditional individual layer crane+bracket of encorbelmenting construction, the utility model can meet bigger lifting capacity, often
The biggest lifting capacity of platform crane can reach 800 tons；
