The screw thread suspension rod 7 of firmware；First backing plate 1 is laid on the top surface of completed beam body；Bearing beam 2 includes being arranged on the first backing plate 1
Bottom plate, be oppositely arranged on bottom plate top plate and two side plates between the bottom panel and top panel be set；First fastener is set
In bearing beam 2, including the first nut 8 and the first anchor plate 9 for being arranged between the first nut 8 and the bottom plate of bearing beam 2；It is very heavy
Top 3 is arranged on the top plate of bearing beam 2；Second backing plate 4 is arranged on the piston of jack 3；Second fastener is arranged on the second pad
On plate 4, including the second nut 10 and the second anchor plate 11 for being arranged between the second nut 10 and the second backing plate 4；3rd pad
Plate 6 is arranged under support support beam 5；3rd fastener is arranged under the 3rd backing plate 6, including the 3rd nut 12 and is arranged on
The 3rd anchor plate 13 between three nuts 12 and the 3rd backing plate 6.
When the cast-in-place simply supported beam that is provided using the present embodiment is constructed with mounting system is dropped, beam body must whole tensioning it is complete
Into outer side mold need to slide onto next girder span, it is necessary to the mounting hole for screw thread suspension rod 7 be set in completed beam body, in beam body
First backing plate 1, bearing beam 2, the first fastener, jack 3, the second backing plate 4 and the second fastener be installed, screw thread suspension rod 7 is through the
Two fasteners, the second backing plate 4, jack 3, bearing beam 2, the first fastener, the first backing plate 1, completed beam body, support to be dropped,
Support support beam 5, in 5 times the 3rd backing plates 6 of installation of support support beam and the 3rd fastener；After installation, below striking
Support column；Perform step 1；It is rotated up the highest that the second nut 10 and the second anchor plate 11 can reach to the piston of jack 3
Highly, the bottom plate that the first nut 8 makes the first anchor plate 9 compress bearing beam 2 is rotated down, starts jack 3, until jack 3
After piston contacts with the second anchor plate 11, piston stops movement, rotates down the second nut 10 to that can not rotate, and is rotated up the
Until the first nut 8 can not rotate under one nut 8 to the top plate of bearing beam 2, screw thread is hung by the first nut 8 and the second nut 10
Bar 7 is fixed；Perform step 2：The piston of jack 3 moves down, and drives screw thread suspension rod 7 to move down, until the first nut 8
After being contacted with the first anchor plate 9, piston stops movement, and screw thread suspension rod 7 is completed once to move down；Repeat step one and step 2
Until decentering of scaffold to specified location, striking.From the foregoing, it will be observed that the mounting system that drops provided using the present embodiment need not
Crane moves support, overcomes when shifting support using crane in the presence of by applying the technical problem of environmental restrictions, while reduce height
Sky lifting risk；The use of jack, has been effectively ensured and has dropped stroke；The position of completed beam body upper installing hole need to only be adjusted
Put, you can adapt to the simple supported box beam of different spans, applicability is wide；Operated by the space below completed beam body, no
Need additional maneuvering spaces；Support from installation site threadingly suspension rod 7 unload fall earthward when, larger position will not occur for horizontal direction
Move, can realize that original position drops substantially；Using the supporting support of support support beam 5, stressed effect is good, increases the stability dropped；The

Border does not produce additional risk factor.
Further, support support beam 5 includes multiple I-steel that wing plate is oppositely arranged and the wing for connecting multiple I-steel
The steel plate of plate；Screw thread suspension rod 7 passes through steel plate.According to actual conditions, the quantity of I-steel can select two or three, with enhancing
The stress-bearing capability of support support beam 5, guarantee, which dropped engineering support support beam 5, to be bent by support.
Further, the first anchor plate 9 is opening anchor plate, i.e., U-typed opening is set on anchor plate.In backing positions
The higher single length of screw thread suspension rod 7 not enough needs that screw thread suspension rod 7 is connected into the installation in use, in beam body by connector
The size in hole, the through hole on the first backing plate 1 and the through hole on the bottom plate of bearing beam 2 should be adapted with the size of connector, in screw thread
When suspension rod 7 falls, the first anchor plate 9 is laid on the first backing plate 1, and opening blocks screw thread suspension rod 7, and screw thread suspension rod 7 is put down in opening
Steady moves down, without because the mounting hole in beam body, the through hole on the first backing plate 1 and the clear size of opening on the bottom plate of bearing beam 2 it is larger
Shake, add the stationarity dropped；When being displaced downwardly to connector the first 1 top of anchor plate of arrival, the first anchor plate is extracted out
1, connector is passed through from bearing beam 2, the first backing plate 1 and beam body.
Further, bearing beam 2 is welded by steel plate.
Further, screw thread suspension rod 7 is fining twisted steel.
Further, the first backing plate 1, the second backing plate 4 and the 3rd backing plate 6 are the steel plate for being provided with through hole.Steel plate and essence
It is common materials to roll screw-thread steel, can be bought from market, and installation is simple, reasonable price.
Embodiment of the present utility model is these are only, not thereby limits the scope of the claims of the present utility model, every utilization
The equivalent structure or equivalent flow conversion that the utility model description is made, or be directly or indirectly used in other related
