Background technology
During prefabricated case beam side bar anti-collision wall construction integrated construction, in small box girder lifting to the concrete bearing mixing up vertical and horizontal gradient, the existence of the horizontal wall inscription due to 2% and the produced load such as anti-collision wall deadweight and template deadweight, there is the possibility toppled in oriented anti-collision wall side in box beam in the process of anti-collision wall construction.
Utility model content
This utility model is for avoiding the deficiency existing for above-mentioned prior art, a kind of prefabricated case beam side bar anti-collision wall construction integration overturn-preventing supporting construction is provided, ensure that the box beam stability in anti-collision wall construction process, eliminate the possibility that box beam is toppled in anti-collision wall construction process, reduce unsafe factor in anti-collision wall construction construction, thus ensureing project progress, improve construction quality.
This utility model adopts the following technical scheme that for solving technical problem
The feature of this utility model prefabricated case beam side bar anti-collision wall construction integration overturn-preventing supporting construction is: for being lifted on the small box girder on coagulation bearing, steel bracket is set between small box girder flange plate and the concrete bearing of anti-collision wall side, makes the small box girder flange plate of steel bracket side obtain support force upwards in bottom；Pull bar is set between opposite side small box girder flange plate and concrete bearing, makes the small box girder flange plate of pull bar side obtain lower pulling force at top.
The construction features of this utility model prefabricated case beam side bar anti-collision wall construction integration overturn-preventing supporting construction lies also in:
Described steel bracket is the framework being welded into by steel profile, and the concrete bearing of corresponding side is placed with sleeper, and described steel bracket props up and stands on described sleeper, arranges anti-skid rubber cushion between the end face and small box girder flange plate of described steel bracket.
Stating pull bar is the pull bar being become Len req by the fining twisted steel that length is 1m by sleeve connection, is embedded with shaped steel and forms groove in the concrete bearing of corresponding side, and the bottom of pull bar utilizes bolt and billet to be fixed in the trench；The top of pull bar is run through the embedded hole in small box girder flange plate and utilizes bolt and billet to be fixed.

Fig. 2 b is steel bracket schematic side view in this utility model；
Number in the figure: 1 concrete bearing, 2 small box girder, 3 anti-collision walls, 4 steel brackets, 5 pull bars, 6 sleepers, 7 anti-skid rubber cushions, 8 embedded holes, 9 choose arm, 10 wet seam widened section, 11 jack resettlement grooves.
Detailed description of the invention
Referring to Fig. 1, in the present embodiment, prefabricated case beam side bar anti-collision wall construction integration overturn-preventing supporting construction is: for the small box girder 2 being lifted on coagulation bearing 1, steel bracket 4 is set between small box girder flange plate and the concrete bearing of anti-collision wall 3 side, makes the small box girder flange plate of steel bracket 4 side obtain support force upwards in bottom；Pull bar 5 is set between opposite side small box girder flange plate and concrete bearing, makes the small box girder flange plate of pull bar 5 side obtain lower pulling force at top.
For due to 2% the existence of horizontal wall inscription and the produced load such as anti-collision wall deadweight and template deadweight, the present embodiment utilizes steel bracket 4 and pull bar 5 support a form drawn with one and in anti-collision wall construction, box beam is played effect that is spacing and that support, it is to avoid topple.
In being embodied as, as shown in Figure 2 a and 2 b, steel bracket 4 is the framework being welded into by steel profile, the concrete bearing of corresponding side is placed with sleeper 6, steel bracket 4 stands on sleeper 6, utilize sleeper 6 and cushion block is set on sleeper to ensure that steel bracket 4 effectively supports, anti-skid rubber cushion 7 being set between the end face and small box girder flange plate of steel bracket 4, so that supporting construction is more firm.
Pull bar 5 is the pull bar being become Len req by Φ 20 fining twisted steel that length is 1m by sleeve connection, is embedded with shaped steel and forms inverted " t " type groove in the concrete bearing of corresponding side, and the bottom of pull bar utilizes bolt and billet to be fixed in the trench；The top of pull bar is run through the embedded hole 8 on small box girder flange plate and utilizes bolt and billet to be fixed, and utilizes billet to increase the contact area between pull bar and groove and embedded hole, it is ensured that stablizing effectively of pull bar system.
It is being the small box girder flange plate of steel bracket side is extended with choose arm 9 shown in Fig. 1, it is anti-collision wall 3 in the outer end choosing arm 9, the small box girder flange plate of pull bar 5 side extends to wet seam widened section 10, the twice that be arranged in parallel in concrete bearing 1 jack mounting groove 11, the jack for shoring small box girder 2 is arranged in jack resettlement groove 11.
