Detailed description of the invention
Embodiment mono-
Shown in Fig. 1 and Fig. 2, the anchoring shelf bracket in the utility model, comprises many tripods 1, supports bracket 2 and platform bracket 3.
Wherein, a straight flange of tripod 1 is for being anchored at Main Pier of Bridges pier shaft 4 sides by anchor rib 5, and another straight flange of tripod 1 is along the horizontal forward extension of direction away from main pier pier shaft 4 sides, and many tripod 1 intervals arranged side by side are arranged. Can be used as preferably: between the tripod 1 on 4 of same pier shafts, can add horizontal connection 10, improve tripod 1 lateral stiffness, laterally connect 10 integral prefabricated installations, be connected on tripod 1.
Support bracket 2 and be arranged on tripod 1 below and the bottom of tripod 1 is formed to jacking support, support bracket 2 and be connected on Main Pier of Bridges pier shaft 4 by anchor rib 5. Support on bracket 2 and offer a pair of through hole passing for anchor rib 5, one end of described anchor rib 5 is embedded in other end level in described Main Pier of Bridges pier shaft 4 and stretches out, and the horizontal external part of described anchor rib 5 is connected with stop nut 6 in its end from described through hole.
Can be used as preferably: the back side of supporting bracket 2 is formed with spacing block set, be reserved with the groove 7 inserting for described spacing block set in Main Pier of Bridges pier shaft 4 sides, be all welded with cross spacing plate 8 in the both sides of described support bracket 2, improve bracket 2 lateral stabilities.
Above many spaced apart tripods 1 arranged side by side, set up platform bracket 3, the bottom of platform bracket 3 forms and is connected with another straight flange of tripod 1. Platform bracket 3 is to be made up of shellfish thunder crossbeam 11, longeron and side crossbeam, can certainly be other structure and the platform bracket 3 with supporting role.
Can be used as preferably: one end of described anchor rib 5 is embedded in other end level in described Main Pier of Bridges pier shaft 4 and stretches out, and also comprises the spacing pressing plate 9 for matching with the external part of described anchor rib 5. The two ends of described spacing pressing plate 9 are respectively arranged with through hole, and the end of described anchor rib 5 external parts passes and be connected with stop nut from described through hole.
Can be used as further preferably: aforementioned anchor rib 5 forms two rows at pre-connection tripod 1 place of Main Pier of Bridges pier shaft 4 sides respectively, two row's anchor ribs 5 lay respectively at the both sides of a straight flange of tripod 1, the two ends of spacing pressing plate 9 are respectively arranged with through hole, and the end of anchor rib 5 passes and be connected with stop nut from through hole. Certainly that, also can adopt other structures but tripod 1 can be anchored at equally to the anchor structure on Main Pier of Bridges pier shaft 4 sides.
When in embodiment mono-, anchoring shelf bracket is constructed, comprise the following steps:
Step 1: preburied component. In the time of the 4 final section construction of Main Pier of Bridges pier shaft, calculate the height of anchoring shelf bracket in the utility model according to design drawing, accurately orient the space pre-buried position of anchor rib 5 at pier shaft 4, and carry out pre-buried.
Be provided with pre-buried steel box at plan installation bracket 2 places and be used to form reserved groove 7, need to add inner support simultaneously, prevent steel box distortion in concreting process, steel box bottom needs to add bar-mat reinforcement, add the local compressive resistance of reinforced concrete, it is straight and perpendicular to pier shaft 4 that pre-buried anchor rib 5 ensures.
Step 2: bracket 2 is installed. In the end a joint pier shaft 4 is built complete form removal and is exposed after reserved groove 7, removes steel box inner support, and cleaning hole slot, then carries out bracket 2 and install, and offers through hole and its back side passed for anchor rib 5 and be formed with spacing block set on bracket 2. The single heavy about 60kg of bracket 2, can adopt the auxiliary installation of manual type or tower crane.
Bracket 2 is located on anchor rib 5 and by spacing block set and inserts reserved groove 7, then by anchor rib 5 stop nut anchoring. At the bottom of checking whether bracket 2 upper padding plates are adjacent to preformed groove, whether lower bolster is adjacent to 4 of pier shafts, if because pre-buried steel box and 4 out of plumb of pier shaft cause upper padding plate warpage or lower bolster cannot be adjacent to pier shaft 4, preferentially adjust upper padding plate and be adjacent to bottom land, lower bolster is by adding the forms such as pading plate and pier shaft 4 faces hold out against. After inspection adjustment is errorless, again tighten anchor rib 5.
After two bracket 2 installations, with reinforcing bar, two brackets 2 are connected to entirety side by side, simultaneously by the 2 top leveling of two brackets. After bracket 2 installations, be welded with cross spacing plate 8, improve bracket 2 lateral stabilities.
Step 3: tripod 1 is installed. Tripod 1 is processed by work steel assembly welding. The heavily about 2t of each tripod 1, be installed on 4 two broad side surfaces of pier shaft, each face is at least installed two tripods 1, can be according to adjustable tripod 1 quantity of load, when installation, ensure that symmetrical tripod 1 is force transferring structure, for 0#, 1# piece load are passed to bracket 2 and pier shaft 4. Coordinating anchor rib 5 to form anchoring and screw upper limit nut in the end of anchor rib 5 by spacing pressing plate 9 forms spacing. Between tripod 1 on 4 of same pier shafts, can add horizontal connection 10, improve tripod 1 lateral stiffness, laterally connect 10 integral prefabricated installations, be welded on tripod 1.
Step 4, platform bracket 3 is installed. After tripod 1 installs, on tripod 1, lift shellfish thunder crossbeam 11, lay longeron at cantilever segment, side crossbeam is laid in wing plate position. Shellfish thunder crossbeam arranges two 16 work bearing beams for 11 times, for striking. 0#, 1# piece two ends cantilever segment are respectively arranged one group three and are arranged individual layer shellfish thunder crossbeam 11 and one group of double individual layer shellfish thunder crossbeam 11, longeron adopts 10# channel-section steel assembly welding to form, at the bottom of being arranged in web and at the bottom of base plate, side crossbeam adopts 36b work steel, side crossbeam falls within on shellfish thunder crossbeam 11, and on position shellfish thunder crossbeam 11 at the bottom of wing plate, left-hand thread one saves 3 meters long 20b channel-section steels, and fixes with bolt, side beam welding, on channel-section steel, ensures that crossbeam is stable. Side form supporting leg falls within on side crossbeam, and side crossbeam level is adjusting tank beam longitudinal gradient, need adjust longitudinal gradient by cutting side form supporting leg mode, after having adjusted, supporting leg is welded on side crossbeam, ensures that side form is stable.
The above-described embodiment that is not limited to of the present utility model; the technical scheme of above-mentioned each embodiment of the present utility model can combined crosswise form new technical scheme each other; all employings are equal to the technical scheme of replacing formation in addition, all drop in the protection domain of the utility model requirement.
