Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, bridge construction bracket bearing assembly, including bracket body 1, lifting top box 2, built-in fitting 3, fixed spiral shell
Bolt 4, the bracket body 1 is that top is big, small bucket-shaped in bottom, in former and later two face levels correspondence positions of the middle part of bracket body 1
Put and respectively open a circular hole, if a round steel pipe 5 is penetrated from circular hole, the two ends of the round steel pipe 5 are welded to connect with two bore edges respectively,
A mobilizable hole door 6 is set in the bottom of the bracket body 1, as shown in Fig. 2 the lifting top box 2 includes box body 7, box top
Panel 8, safe blend stop 9, the box body 7 are obturator, and the external diameter of the box body 7 and the internal diameter gap on the top of bracket body 1 are matched somebody with somebody
Close, the box body 7 can be entered bracket body 1 by the upper opening of bracket body 1, the box top plate 8 is located at the top of box body 7, institute
The external diameter for stating box top plate 8 is more than the external diameter of the upper opening of bracket body 1, and the safe blend stop 9 is arranged vertically within box top plate 8
On, as shown in figure 3, the built-in fitting 3 includes pre-embedded steel slab 10, long nut 11, the long nut 11 is vertically fixedly connected on pre-
The one side of steel plate 10 is buried, the fixing bolt 4 coordinates with the screw thread of long nut 11, and the screw rod of the fixing bolt 4 may pass through round steel
Pipe 5 is threadedly coupled with the long nut 11 being embedded in concrete.
As shown in figure 4, bracket bearing assembly is the main load part of erection without scaffolding, when it is implemented, bracket body 1
It is welded by thickness for 6mm steel plate, the bracket first half is rectangle, lower half is trapezoidal, and inside can be with sand loading.Lift top box
2 be also the closing box that steel plate is welded into, and its external diameter size is more slightly smaller than the upper opening internal diameter of bracket body 1, with can be successfully
The sand that fill in bracket body 1 ensures in bracket body 1 again is unlikely to the effusion from top and is advisable.
Pier stud answers pre-buried built-in fitting 3, before pier stud concreting, should set the position of built-in fitting 3 before construction,
And the measure that properly protects, it is to avoid cement mortar, which is immersed in nut, damages nut.
Completion is poured Deng pier stud, after form removable, using the screw rod of fixing bolt 4 through round steel pipe 5 with being embedded in coagulation
Long nut 11 in soil is threadedly coupled, and bracket bearing assembly is fixed on pier stud.Sand is filled out in the inside of bracket body 1, and
Ensure that sand top surface is smooth (sand top surface will below bracket top surface at least 10cm), lifting top box 2 is finally installed.
As shown in figure 5, both sides are symmetrically installed two bracket bearing assemblies before and after pier stud, bracket bearing assembly install with
Afterwards, I-steel 14 is installed on lifting top box 2, safe blend stop 9 is to prevent I-steel 14 from breakking away.I-steel 14 is held as main
Weight beam rigidity must is fulfilled for requirement, and the model of I-steel 14 is determined according to the construction loads of bent cap, laying side on I-steel 14
Wood 15, the top of the lumps of wood 15 can lay template 17.
As indicated with 6, in order to ensure safety, the I-steel 14 on both sides is connected with girt 16 before and after pier stud 18, water
The number of horizontal drawing bar 16 is determined on a case-by-case basis.
