[technical field]

The present invention relates to the technical field of bracket, especially a kind of technical field of the hanging bracket of end bay Cast-in-Situ Segment.

[background technique]

Bridge generally uses cantilever construction, and generally console is used to construct end bay Cast-in-Situ Segment.But due to Some Field in Bridge Site Located are located at high oblique zanjon, and topography is dangerously steep, and based process is more difficult, therefore conventional console is difficult to meet The construction at scene.In addition, the cast-in-place section concrete of end bay when pouring, in order to eliminate the unbalanced weight of transition pier two sides, usually needs Counterweight is carried out to bracket by loading the objects such as sandbag and water tank on transition pier access bridge side, this mode needs to expend largely Material resources and manpower, construction cost investment is big, and security risk is big.

[summary of the invention]

The object of the invention is to solve the problems of the prior art, a kind of hanging bracket of end bay Cast-in-Situ Segment is proposed, it can Guarantee that structure is reasonable, securely and reliably, and can reach guarantee construction quality, speeds up the work, reduces engineering cost, greatly It reduces workload and mitigates the good result of labor intensity of workers in ground.

To achieve the above object, the invention proposes a kind of hanging bracket of end bay Cast-in-Situ Segment, including pre-embedded steel slab, bracket are oblique Support and distribution beam, if the pre-embedded steel slab includes along the first steel plate along bridge to the dry plate equidistantly distributed for being embedded in bridge pier side With the second steel plate, second steel plate is located under the first steel plate and stretches out from the other side of bridge pier, and the bracket diagonal brace includes Bottom end tilts the first diagonal brace and the second diagonal brace of embedment bridge pier two sides respectively, and the top and middle part of first diagonal brace are respectively with the The middle part of one steel plate is mutually welded and fixed with the end of the second steel plate, and the top of second diagonal brace is mutually welded with the end of the second steel plate Fixation is connect, the distribution beam is fixed on the first steel plate.

Preferably, being welded with several first supports vertically at bridge pier between first steel plate and the second steel plate Beam.

Preferably, oblique weld has several second supporting beams between first supporting beam and the first diagonal brace.

Preferably, the oblique weld between the first diagonal brace and the second diagonal brace has several third branch to second steel plate respectively Support beam.

Preferably, being welded with lateral connection channel steel between first diagonal brace and between the second diagonal brace.

Preferably, the distribution beam includes the transverse distribution beam being fixed on the first steel plate and is fixed on transverse distribution Longitudinal distribution beam on beam.

Preferably, further including the steel strand wires tail rope being fixed between the second steel plate and bridge pier, the steel strand wires tail rope The side of the second diagonal brace is equipped with positioned at bridge pier and both ends pass through anchorage respectively and are fixed on the second steel plate and bridge pier.

Beneficial effects of the present invention: the present invention is formed by pre-embedded steel slab, the first diagonal brace and distribution beam in the side of bridge pier Hanging bracket can efficiently use the unbalanced weight when bearing capacity resistance concreting of bridge pier itself；By making to be pierced by bridge The second diagonal brace that second steel plate of the pier other side is embedded on bridge pier with inclination is mutually fixed, and cooperates the tensioning of steel strand wires tail rope Power, which is used as, matches heavy load, to resist moment of flexure suffered by bridge pier in access bridge side；It is perpendicular by being arranged at bridge pier in pre-embedded steel slab The first straight supporting beam, the case where effectively avoiding hanging bracket from turning on one's side to Cast-in-Situ Segment side.

Feature and advantage of the invention will be described in detail by embodiment combination attached drawing.

[specific embodiment]

Refering to fig. 1, a kind of hanging bracket of end bay Cast-in-Situ Segment of the present invention, including pre-embedded steel slab 2, bracket diagonal brace 3 and distribution beam 4, if the pre-embedded steel slab 2 include along bridge to the first steel plate 21 of the dry plate equidistantly distributed for being embedded in 1 side of bridge pier and the Two steel plates 22, second steel plate 22 are located under the first steel plate 21 and stretch out from the other side of bridge pier 1, the bracket diagonal brace 3 Including bottom end respectively tilt embedment 1 two sides of bridge pier the first diagonal brace 31 and the second diagonal brace 32, the top of first diagonal brace 31 and End of the middle part respectively with the middle part of the first steel plate 21 and the second steel plate 22 is mutually welded and fixed, the top of second diagonal brace 32 with The end of second steel plate 22 is mutually welded and fixed, and the distribution beam 4 is fixed on the first steel plate 21, first steel plate 21 and It is welded with several first supporting beams 6, first supporting beam 6 and the first diagonal brace 31 vertically at bridge pier 1 between two steel plates 22 Between oblique weld have several second supporting beams 7, second steel plate 22 inclines between the first diagonal brace 31 and the second diagonal brace 32 respectively Inclined weld is connected to several third supporting beams 8, is welded with lateral connection between first diagonal brace 31 and between the second diagonal brace 32 Channel steel 5, the distribution beam 4 include be fixed on transverse distribution beam 41 on the first steel plate 21 and be fixed on transverse distribution beam 41 it Upper longitudinal direction distribution beam 42, further includes the steel strand wires tail rope 9 being fixed between the second steel plate 22 and bridge pier 1, the steel strand wires balance Rope 9 is located at side of the bridge pier 1 equipped with the second diagonal brace 32 and both ends pass through anchorage respectively and are fixed on the second steel plate 22 and bridge pier 1.

The course of work of the present invention:

Firstly, stress point of the pre-embedded steel slab 2 as bracket diagonal brace 3 is arranged in the pier shaft of bridge pier 1, make bracket diagonal brace 3 and 2 firm welding of pre-embedded steel slab forms calf support as support system, and transverse distribution beam 41 and longitudinal point are then set up above Operation platform is formed with beam 42 to construct.

The present invention forms hanging bracket in the side of bridge pier by pre-embedded steel slab, the first diagonal brace and distribution beam, can be effectively sharp Unbalanced weight when concreting is resisted with the bearing capacity of bridge pier itself；Pass through the second steel plate for making to be pierced by the bridge pier other side The second diagonal brace being embedded on bridge pier with inclination is mutually fixed, and is cooperated the stretching force of steel strand wires tail rope to be used as and matched heavy load, from And moment of flexure suffered by bridge pier is resisted in access bridge side；By the way that the first vertical supporting beam is arranged at bridge pier in pre-embedded steel slab, have The case where effect avoids hanging bracket from turning on one's side to Cast-in-Situ Segment side.

Above-described embodiment is the description of the invention, is not limitation of the invention, after any pair of simple transformation of the present invention Scheme all belong to the scope of protection of the present invention.
