His structure but equally tripod 10 can be anchored at the anchor structure on 13 side of Main Pier of Bridges pier shaft.
When being constructed by anchoring shelf bracket in embodiment one, comprise the following steps：
Step 1：Preburied component.When 13 final section of Main Pier of Bridges pier shaft is constructed, the present invention is calculated according to design drawing
The height of middle anchoring shelf bracket, is accurately positioned out anchor rib 14 in the pre-buried position in space of pier shaft 13, and carries out pre-buried.
Pre-buried steel box is provided with bracket 2 for forming reserved groove 16 intending installing, while internal support need to be added, is prevented
Only steel box deformation in concreting process, steel cassette bottom portion need to add bar-mat reinforcement, strengthen concrete local compressive resistance, pre-buried anchoring
Muscle 14 ensures straight and perpendicular to pier shaft 13.
Step 2：Bracket 2 is installed.Pour in final section pier shaft 13 and finish after form removal exposes reserved groove 16, remove
Steel box inner support, clears up hole slot, then carries out bracket 2 and install, and the through hole and its back of the body passed through for anchor rib 14 is offered on bracket 2
Face is formed with spacing block set.Bracket 2 is single to weigh about 60kg, and manual type or tower crane auxiliary can be adopted to install.
Bracket 2 is located on anchor rib 14 and by spacing block set insertion reserved groove 16, then by the limit of anchor rib 14
Position nut anchoring.Check whether 2 upper padding plate of bracket is adjacent to preformed groove bottom, whether lower bolster is adjacent to 13 face of pier shaft, if because of pre-buried steel
Box causes upper padding plate warpage or lower bolster be adjacent to pier shaft 13 with 13 face out of plumb of pier shaft, then preferentially adjust upper padding plate and be adjacent to groove
Bottom, lower bolster are held out against with 13 face of pier shaft by forms such as cushioning steel plates.Check that adjustment tightens anchor rib 14 after errorless again.
Two brackets 2 are connected as into entirety with reinforcing bar after two 2 installations of bracket side by side, while two brackets 2 are pushed up
Leveling.Cross spacing plate 17 is welded with after 2 installation of bracket, 2 lateral stability of bracket is improved.
Step 3：Tripod 10 is installed.Tripod 10 is processed by the weldering of work steel group.Each tripod 10 weighs about 2t, installs
On 13 two broad side surfaces of pier shaft, two tripods 10 are at least installed in each face, can be according to load scalable tripod 10
Quantity, ensures during installation that symmetrical tripod 10 is force transferring structure, for 0#, 1# block load is passed to bracket 2 and pier shaft
13.Coordinate anchor rib 14 to form anchoring and upper limit nut is screwed in the end of anchor rib 14 by spacing pressing plate 18 form limit
Position.Laterally connection 19 can be added between tripod 10 on 13 face of same pier shaft, 10 lateral stiffness of tripod is improved, is laterally coupled
19 integral prefabricated installations, are welded on tripod 10.
Step 4, platform bracket 12 are installed.Tripod 10 lifts shellfish thunder crossbeam 20 on tripod 10 after installing,
Cantilever segment lays longeron, flap position laying side crossbeam.Shellfish thunder crossbeam arranges double 16 work bearing beams for 20 times, for striking.0#、
1# blocks two ends cantilever segment respectively arranges one group of three row's monolayer shellfish thunder crossbeam 20 and one group of double monolayer shellfish thunder crossbeam 20, and longeron is adopted
The weldering of 10# channel-section steels group is formed, and is arranged in web bottom and base plate bottom, and side crossbeam adopts 36b work steel, side crossbeam to fall within shellfish thunder crossbeam 20
On, on wing plate bottom position shellfish thunder crossbeam 20, left-hand thread one saves 3 meters long 20b channel-section steels, and blending bolt is fixed, and side beam welding is in channel-section steel
On, it is ensured that crossbeam is stable.Side form supporting leg is fallen within the crossbeam of side, side crossbeam level, is adjustment box beam longitudinal gradient, need to be by cutting side form
Supporting leg mode adjusts longitudinal gradient, supporting leg is welded on the crossbeam of side after the completion of adjustment, it is ensured that side form is stable.
