Structure, the structure of bottom girder have the left lower transverse beam being connected in steel harness system, and the left lower transverse beam upper and lower ends connect respectively
There are underframe longitudinal member and bottom joist, it is connected with upper and lower ends on the right side of the underframe longitudinal member and is connected to bottom joist and underframe longitudinal member
On lower right frame beam, be provided with multiple bed die crossbeams above the underframe longitudinal member, bed die steel be provided with the bed die crossbeam
Panel, the structure of bottom girder are symmetrical arranged along main couple, also have the block being connected on main couple above the bed die steel facing
Section box beam.
Filled preferably, being both provided with the bottom joist fixed with bottom joist on the left lower transverse beam and lower right frame beam and anchoring
Put, effectively increase the stability of bottom joist, and then improve the reliability and security of total, reduce security risk.
, can be with preferably, be equipped with the bottom joist anti-drop device for being used for preventing that bottom joist from coming off on the right side of the bottom joist
Effectively prevent bottom joist from coming off.
Preferably, block box beam connection is with the suspender belt anchor for being used to fix with bottom joist, can be by collet
Beam is firmly fixed in block box beam, and in order to improve the non-deformability of whole device, bottom joist is arranged on lower right frame beam and scratches
Maximum position is spent, can be greatly reduced because of the deformation that amount of deflection is excessive and produces, and then reduce the possibility of faulting of slab ends between bottom plate block
Property.
Preferably, the bed die crossbeam is I-steel.
Compared with prior art, the utility model is beneficial in that：By adding 2 groups of bottom joists, bottom joist is compared
In truss weight smaller, the lower flexure strain of left and right bottom end rail is reduced, reduces the section ruler of left and right bottom end rail to greatest extent
It is very little, the steel using amount of the wide box girder cradle construction device with bottom joist is saved, increases the width with bottom joist in walking process
The safety coefficient of width box beam cradle construction device；Deformation accumulation of the rear bottom end rail in Hanging Basket walking process is reduced, is solved
The problem of faulting of slab ends between bottom plate block.
