Optionally embodiment, wheel shaft are bearing pin or bolt.
It should be noted that in the case where not conflicting, the spy in embodiment and/or embodiment in the utility model
Sign can be combined with each other.
Crossbeam of the present utility model is horizontal positioned in processing and installation process, and the first flange plate 12 is in second wing
The top of listrium 13.Processing of the present utility model and installation process comprise the following steps：
Step 1：The design processing of hinge 3
The design of hinge 3 mainly considers its stability under loading, simple to operate, does not influence structure normal function.Material purchases side
Just, processing is made simply, quality control is easily achieved.
Hinge 3 uses thickness as 20mm, and material Q345B steel plate makes.It is divided into three parts composition：One is to be welded on steel
Base joint 31 on web 11, two is are welded on the rotary connector 32 on bolt clamping plate 2, and three between two connectors
M14 bearing pin (or bolt)；In the function and structure, needed between two connectors (base joint 31 and rotary connector 32)
Reserved 2mm gaps, while base joint 31 need to be below rotary connector 32, the pin-and-hole both during for adjusting installation bolt
The difference of interdigit；Wheel shaft of the bearing pin (or bolt) as rotation.When wheel shaft uses bolt, ensure that nut under, is screwed onto nut
Contact base joint 31.
Base joint 31 and the processing of rotary connector 32 use Numerical control cutting, and fixture by base joint 31 or rotates
Unified drilling is carried out after 32 batches of clamping of connector.
The total weight in installation process of bolt clamping plate 2 is undertaken by hinge 3, and the quantity that hinge 3 is arranged is by bolt clamping plate 2
Weight, which calculates, to be determined.The most heavy most heavy monolithic of bolt clamping plate 2 reaches 392KG, can meet to require using 3 connections of hinge 3.
Fig. 7 is the Force Calculation schematic diagram of hinge 3.
As shown in fig. 7, according to different operating modes, it is lower individually to list the maximum weighted numerical value of hinge 3.
The horizontal direction force max of hinge 3：Fa=Fb=Fc=1962.5N
The vertical applied force max of hinge 3：Fa=Fb=Fc=1274N
The weld seam of hinge 3 is cut checking computations：Fy >=N/nhe*lw≤[fw]=2.18N/mm2≤[200], weld strength meet.
The bearing capacity of bolt is provided to calculate by following equation：τ=4F/ (π ы 2)≤[τ]=12.75≤[140]
Stressed bolt bearing capacity meets to require.
Step 2:Bolt clamping plate 2 is with brill
Because large-scale steel beam joint bolt quantity is more, up to 128 when the single bolt hole count of bolt clamping plate 2 is most.To be true
The drilling precision and efficiency of bolt clamping plate 2 are protected, the standard component of bolt clamping plate 2 is first fabricated separately before drilling, then bolt clamping plate 2 is existed
Carry out matching somebody with somebody on radial drill and drill hole.The bolt clamping plate 2 that polylith matches is stacked together, is placed on drilling machine and is fixed with pressing plate
Afterwards, it is another with drilling after being positioned using the standard component of bolt clamping plate 2, it is ensured that the bolt clamping plate 2 matched in single batch makes
Error is identical, reaches the effect for improving bolt penetration hole rate.
Step 3：Steel beam web plate 11 drills
When steel beam web plate 11 drills, the supporting bolt clamping plate 2 for having completed drilling is matched simultaneously with steel beam web plate 11
With clamp, set brill is then carried out, forms a unified drilling batch, 11 sets of steel beam web plate need to carry out preboring positioning when boring
Prevent from damaging the hole wall of bolt clamping plate 2.Realize and checked oneself certainly between formation process between the bolt clamping plate 2 of drilling and the drilling of steel beam web plate 11
Inspection.
Step 4：Bolt clamping plate 2 assembles
After the completion of the drilling of steel beam web plate 11, upset bolt clamping plate 2 is assembled, bolt clamping plate 2 and girder steel abdomen during assembling
Plate 11 is fixed using refined rushing and bolt, it is ensured that hole position aligns, realize that steel beam web plate 11 drills, bolt clamping plate 2 assembles and
Hinge 3 is assemblied in same workshop section and completed, and avoids Secondary Transport.
Step 5：Hinge 3 assembles
The assembling of hinge 3 is inserted during girder steel bolt clamping plate 2 assembles, the rigging position of hinge 3 is in strict accordance with in-depth
Design drawing carry out, avoid position offset after influence high-strength bolt end twist.Ensure that pin-and-hole passes through pin on hinge 3 after positioning
After axle (or bolt) and situation without interim card, then it is welded and fixed, striking position must avoid on hinge 3 during welding
Striking arc crater is caused on component mother metal.Finally remaining welding will be continued to complete after bolt clamping plate 2 and girder steel partition, welded in title
Prevent from welding deformation using CO2 gas shielded arc welding small current weldings and prevent from splashing to influence high-strength bolt rubbing surface quality.Hinge
Bolt clamping plate 2 assembles together with girder steel part again after the completion of chain 3 welds, and is fixed two bolt clamping plates 2 with installation bolt.
Step 6：Packing and transporting
All production process are completed and after impeller blasting, girder steel are packed.Using waste and old drawing and adhesive tape by bolt
After carrying out paint spraying after clamping plate 2 and weld seam parcel, component entrucking that girder steel and bolt clamping plate 2 are integrally formed be sent to scene with
It is to be installed.Avoid traditional mode from individually numbering connecting plate to pack, installed again after matching board after checking after showing up.
Step 7：Colligation is lifted by crane
Before girder steel colligation, node location packing adhesive tape and wrapping paper are removed, clears up steel beam surface dirt；To producing floating rust
Connecting plate and rubbing surface derusted before lifting, open bolt clamping plate 2, the safety of school inspection hinge 3 and function is complete again
Standby situation, packages installation bolt with instrument and ties, after having drawn safety rope and having slipped rope, 2 colligation liftings.
Step 8：Installation in place
Fig. 8 is steel girder erection schematic diagram.
After girder steel is lifted near installation site, operating personnel are by slipping the stable girder steel of rope, adjustment girder steel both ends inner side
Two open angles of bolt clamping plate 2, from outer lateral Center-Periphery Structure direction translation installation.As shown in figure 8, after in place, tower crane off the hook
After contacting steel column bracket to girder steel both ends location-plate 14, bolt clamping plate 2 is closed, installation bolt is put on and realizes that girder steel is modular integrated
Formula is installed.Coordinate adjusting hole away from, it is ensured that common installation bolt quantity by must not be less than using punch hole joint devious
The 30% of node bolt sum, and must not be less than two or by number of computations.
Step 9：High-strength bolt is constructed
After the steel girder erection in a framework finishes to form stable frame, in time measurement correction, then replace installation it is high-strength
Bolt.High-strength bolt is forbidden to penetrate by force when installing.When that can not freely pass into, coordinate rushing adjustment or reamer finishing, finishing
Aperture afterwards cannot be greater than 1.2 times of high-strength bolt diameter.High-strength bolt needs to twist eventually again after first just twisting, and first screwing torque is turned round for construction
50% or so of square, and in the way of central order is outwards tightened, and complete to twist eventually within 24h hours.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art can readily occur in change in the technical scope that the utility model discloses
Or replace, it should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be with the power
The protection domain that profit requires is defined.
