Description

A kind of upper front beam suspension system of suspended pouring construction hanging basket

Technical field

The utility model belongs to continuous beam, continuous rigid frame bridge cantilever construction engineering field, and in particular to a kind of cantilever is applied The upper front beam suspension system of work Hanging Basket.

Background technology

Continuous beam, continuous rigid frame bridge are built because its structure is with excellent mechanical property and economic performance across river valley bridge It is used widely in if, and cantilever method pouring construction technology is continuous beam, Continuous Rigid-framed Girder construction one preferred technique, Hanging Basket is then Cantilever method pouring construction necessary equipment.

As shown in Figure 1, the gusset plate 3 that upper front beam 1 is supported directly upon two main couple of Hanging Basket, 2 front end by traditional Hanging Basket pushes up Portion, the mounting means need 3 top-slitting of gusset plate, processing and installation required precision is high；For upper beam before installation and hang Band and the length for adjusting suspender belt, will be arranged operating platform 4 on preceding upper beam, and operating platform 4 hangs in the sky, difficulty above and below personnel Greatly, construction is inconvenient and there are security risks；It is directly connected to suspender belt 5 on upper front beam 1, since upper front beam position is higher, extends The length of suspender belt, causes suspender belt deflection bigger than normal, influences structural stability；Suspender belt length is not easy to adjust in above structure, especially It is complicated to tiny Pass line adjustment process and control difficulty is big.

Invention content

The purpose of this utility model is that for the above structure defect of existing Hanging Basket, one kind is provided and is easily installed, operates The upper front beam suspension system for the suspended pouring construction hanging basket that safety, stable structure, suspender belt length are conveniently adjusted.

The technical solution of the utility model is as follows：

A kind of upper front beam suspension system of suspended pouring construction hanging basket, including front beam on two main couples and one, feature exist In：Two short columns are fixedly installed on the upper front beam, a connecting plate is respectively welded in the both sides of each short column, each short vertical The connecting plate of column both sides is connect with the gusset plate of a main couple by axis pin respectively；The bottom of the upper front beam is equipped with multipair hang Ear, sets a horizontally disposed distribution beam respectively below each pair of lifting lug, and the both ends of every distribution beam are separately connected one and vertically set The flower basket bolt set, the two flower basket bolt upper ends at every distribution beam both ends respectively with a pair of of lifting lug pin joint of upper front beam bottom, The lower end of flower basket bolt and distribution beam pin joint；1 or 2 suspender belts, every suspender belt difference are separately connected in the middle part of every distribution beam It is connect with skid beam in the edge of a wing skid beam or case of Hanging Basket or bottom basket front beam.

The utility model gives full play to rod piece stress performance, and stress is clear, simple in structure, high capacity, upper front beam peace Dress is convenient, and construction personnel can be operated on bridge floor, it is not necessary to and high-altitude operation platform is set up, worker high-altitude suspension operation is reduced, Working security is improved, difficulty of construction is reduced；Suspender belt length adjustment is convenient, is especially adjusted to tiny absolute altitude accurate.

Specific implementation mode

As shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5, the utility model includes front beam 1 on two main couples 2 and one, the cross of going forward Two short columns 6 are fixedly installed on beam 1, a connecting plate 7 is respectively welded in the both sides of each short column 6, each short column both sides Connecting plate 7 is connect with the gusset plate of a main couple 3 by axis pin 8 respectively；The bottom of the upper front beam 1 is equipped with multipair lifting lug 9, Set a horizontally disposed distribution beam 10 respectively below each pair of lifting lug 9, the both ends of every distribution beam 10 are separately connected one vertically The flower basket bolt 11 of setting, two flower basket bolts, 11 upper end at every distribution beam both ends a pair of of lifting lug with upper front beam bottom respectively 9 pin joints, lower end and 10 pin joint of distribution beam of flower basket bolt 11；The middle part of every distribution beam 10 is separately connected 1 or 2 suspender belts 5, Every suspender belt 5 is connect with skid beam 13 in the edge of a wing skid beam 12 or case of Hanging Basket or bottom basket front beam 14 respectively.

As shown in Figure 4, Figure 5, the pedestal 15 of 1 or 2 inverted U, each bottom is fixedly installed in the top surface of every distribution beam 10 A centre-hole jack 16 is vertically installed in the top surface of seat 15, and each pedestal and jack pair should install a suspender belt 5, described to hang 5 Band uses fining twisted steel, every suspender belt 5 to sequentially pass through distribution beam 10, pedestal 15 and centre-hole jack 16 from bottom to top, hang The top of the jack 16 is protruded from 5 upper end, and first bolt-nut 17 that is spirally connected, be located at the pedestal 15 in suspender belt 5 Position between distribution beam 10 is spirally connected the second bolt-nut 18, sliding in the lower end of suspender belt 5 and the edge of a wing skid beam 12 or case of Hanging Basket Beam 13 or bottom basket front beam 14 connect.

The utility model can be pre-machined by factory, and upper front beam and distribution beam are made of Two bors d's oeuveres channel steel, are being constructed Scene is installed by bolt axis pin, when installation first by short column, connecting plate and upper front beam it is integrally mounted after integral hoisting arrive On main truss gusset plate.After upper front beam is installed in place, in below the crossbeam installation flower basket bolt and the distribution beam of going forward, installation, Depth of beam is distributed by adjusting the length adjustment of flower basket bolt, it is ensured that it is in proper height and facilitates operation.Then again Suspender belt is installed, skid beam in bottom basket and flange plate skid beam and case is connected finally by suspender belt.

When utility model works, when needing to adjust the height of distribution beam 10, it can be adjusted by rotating flower basket bolt 11. The length of suspender belt 5 can be adjusted by the cooperation of punching jack 16 and the first adjusting nut 17, the second adjusting nut 18.Fig. 4, Under state shown in fig. 5, when needing adjustment extension suspender belt 5 downwards, first the first adjusting nut 17 is rotated up, away from 16 top certain distance of centre-hole jack, then start jack 16 make its be elongated to top withstand the first nut 17 again, The second nut 18 is rotated then up away from 10 top surface certain distance of distribution beam, then shrinks jack 16, keeps suspender belt 5 whole It falls, recycles aforesaid operations, until suspender belt 5 reaches the length of needs；When needing to be lifted up suspender belt 5, operating process on the contrary, So that jack 16 is extended the first nut 17 of jacking upwards, so that the second nut 18 is left 10 top surface of distribution beam, then rotate down Second nut 18 makes it resist 10 top surface of distribution beam again, then shrinks jack 16, rotating the first nut 17 still further below makes it It resists at the top of jack 16, then extends the upward jacking of jack 16 again, recycle aforesaid operations, until the promotion of suspender belt 5 is arrived need to The height wanted.
