Fig. 2 is Fig. 1 lateral structure schematic diagram；
In figure, 1 it is pylon column, 2 is upper free bearing, 3 is lower free bearing, 4 is steel box-girder, 5 is upper anchor case, 6 to cast anchor case, 7
It is bearing beam for hoist cable, 8,9 be extending beam, 10 be walking beam, 11 be overturning-preventing hawser, 12 be top removal device, 13 has been footstock.
Embodiment
The utility model is further elaborated below in conjunction with the accompanying drawings.
With reference to shown in figure 1, the proud one embodiment of the utility model is a kind of hanging available for Large-span Steel Box Beam construction
Sarasota frame, including pylon column 1, the lower end of the pylon column 1 is fixed with free bearing 2, and upper free bearing 2 need to be arranged on lower free bearing 3
On, lower free bearing 3 is fixed on steel box-girder 4, that is, is placed in the top of steel box-girder 4；What is more important, in the both sides of pylon column 1
It is both needed to install anchor case 5 and two upper anchor casees 5, the both sides of near middle is installed in the case 6 that casts anchor, the i.e. both sides on the top of pylon column 1
Two casees 6 that cast anchor are installed, need to also be in the fixed hoist cable 7 in the inside of upper anchor case 5 and the case 6 that casts anchor, the effect of the hoist cable 7 is by pylon
It is connected between column 1 and steel box-girder 4, for being entered by pylon column 1 by hoist cable 7 to the steel box-girder 4 of the both sides of pylon column 1
Row drawing is hung.
In the present embodiment, by the erection tower column 1 on steel box-girder 4, by the upper anchor case 5 on pylon column 1 with
Anchor case 6 is attached by the extended position of hoist cable 7 and steel box-girder 4, so play it is fixed in the presence of, avoid steel box-girder 4 from existing
It is turned under discounting as making steel box-girder 4 from a branch pier base to another buttress caused by front end is hanging during reach
Remain horizontal during seat reach, even if distance is excessive without therefore Temporary Piers are set between branch pier base, be advantageous to be lifted
The convenience of Large-span Steel Box Beam construction.
Referring again to shown in Fig. 1, in another embodiment of the present utility model, to make pylon column 1 be arranged on steel box-girder 4
The upper uniformity with stress, can also fix a bearing beam 8 between above-mentioned lower free bearing 3 and steel box-girder 4, also can by bearing beam 8 with
Lower free bearing 3, steel box-girder 4 are welded as a whole；So as to further lift the stability that pylon column 1 is arranged on steel box-girder 4.Simultaneously
Drawn for raising sling 7 and hang the stability of steel box-girder, can realized by way of increasing the quantity of hoist cable 7, this mode is also more
It is easy；With reference to shown in Fig. 2, the upper anchor case 5 on pylon column 1 is specially disposed as multiple, Ran Hou with the case 6 that casts anchor first
Each upper anchor case 5 is with being respectively and fixedly provided with hoist cable 7 in the case 6 that casts anchor, and the steel with the both sides diverse location of pylon column 1 respectively of hoist cable 7
Box beam 4 is attached, and then the stability that further lifting steel box-girder 4 moves forward on the whole.
Referring still to shown in Fig. 1, in utility model is used to solve the more preferred one embodiment of technical problem, in order to
Prevent pylon column 1 from toppling over after being arranged on steel box-girder, can be on the basis of said structure, in the bottom of pylon column 1
One extending beam 9 is installed, gone out as shown, extending beam 9 is starting point with pylon column 1, is extended to its both sides；And this prolongs
Beam 9 also needs to be arranged on walking beam 10 by bearing；So as to each at the both ends of extending beam 9 and the near middle of pylon column 1
One or one group of installation overturning-preventing hawser 11 are installed；And for the convenience of the installation of lifting pylon column 1, above-mentioned walking beam 10 is pacified
The angle of dress is to make it perpendicular with steel box-girder 4 in the horizontal plane；, can be in pylon column by the walking beam 10 of foregoing angle
During 1 installation, by it from the side of steel box-girder 4, the position at lower free bearing 3 is pushed into along walking beam 10, by the upper of the bottom of pylon column 1
Free bearing 2 is arranged on lower free bearing 3 by bearing pin, and then simplifies the mounting means of pylon column 1.
Further, for ease of adjusting its upper-lower position when pylon column 1 is installed, it is easy to enter upper free bearing 2 and lower free bearing 3
It row alignment, because the weight of pylon column 1 itself is larger, therefore need to typically use outside crane gear to be aided in, and send out
A person of good sense considers the limitation of Large-span Steel Box Beam construction site, the top removal device 12 directly installed on steel box-girder 4, top lifting dress
Putting 12 can be directly using conventional jack, according to the jack of the weight of pylon column 1 selection dimension.Foregoing top lifting
The installation site of device 12 need to be corresponding with the bottom of extending beam 9, and also needs to set and top removal device 12 in the bottom of extending beam 9
Corresponding plays footstock 13, as shown, is preferably respectively mounted a top lifting on the steel box-girder 4 of the lower both sides of free bearing 3
Device 12.
As mentioned here above, as shown in Fig. 2 tower with suspended cable upper anchor case 5 need to be with the case 6 that casts anchor by each in use
From hoist cable 7 be connected with steel box-girder 4；And pylon column 1 can use truss structure, i.e., at it more with vertical for ease of removing
There is more transverse directions, longitudinal direction and skewed horizontal load bar between post, while being easy to be lifted pylon 1 intensity of column, reduce its own
Weight.
