Description
Technical field
The utility model relates to a kind of carriage, relates in particular to a kind of supporting bracket of bridge construction.
Background technology
With the transportation development, bridge construction comprises that river bridge, land bridge are more and more.Bridge pier is the basis of building in bridge construction.Usually, attached pier carriage construction is adopted in highway, No. 0 piece construction of Railway Bridges And Piers, and pre-buried large block plate in the present pier of conventional bracket is with shelf bracket monolithic hoisted in position and pre-embedded steel slab welding after assembly welding is finished under the bridge.But there is following problem in conventional bracket in work progress: high-altitude vertical welding, weldquality are difficult to guarantee, have potential safety hazard; Weld seam is long, the overhead welding workload is large, the carriage installation period is long; Need to use during dismounting gas welding with carriage by cutting off on the pre-embedded steel slab, remove difficulty, and serious through the shelf bracket damage after the gas welding cutting, should not repeatedly use, turnover property is poor, the carriage input amount is large; After carriage is removed, realize that pre-buried large block plate is difficult to process, affect the bridge pier presentation quality.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of supporting bracket of bridge construction, be installed on bridge pier, described supporting bracket of bridge construction comprises high-strength split bolt, lower high-strength split bolt, upper free bearing plate, lower free bearing plate, upper chord, hound, described high-strength split bolt, lower high-strength split bolt is horizontally disposed with and is fixedly connected in described bridge pier, described high-strength split bolt, lower high-strength split bolt connects described bridge pier, described upper free bearing plate is fixedly connected on the end of described high-strength split bolt, lower free bearing plate is fixedly connected on the end of described lower high-strength split bolt, described upper free bearing plate, upper chord, hound, lower free bearing plate is hinged successively.
Further improvement of the utility model is that described lower high-strength split bolt and upper high-strength split bolt are parallel to each other.
Further improvement of the utility model is that described lower high-strength split bolt is arranged under the described high-strength split bolt.
Further improvement of the utility model is that described upper chord adopts the Q235 steel.
Further improvement of the utility model is that described hound adopts the Q235 steel.
Further improvement of the utility model is that described upper free bearing plate adopts the Q345 steel.
Further improvement of the utility model is that described lower free bearing plate adopts the Q345 steel.
Compared to prior art, the upper free bearing plate of supporting bracket of bridge construction of the present utility model, lower free bearing plate adopt carbon dioxide gas arc welding, and the second-order weld weldquality is good.Upper free bearing plate, lower free bearing plate adopt high-strength split bolt to wearing bolt, and elastic deformation is effective.After carriage was removed, the presentation quality of bridge pier was good.Supporting bracket of bridge construction of the present utility model is convenient to adjust spacing, is applicable to different beam types, and versatility, turnover property are strong, are applicable to the high density Construction of continuous beam, save construction cost, improve operating efficiency, reduce construction safety risk.
Description of drawings
Fig. 1 is the structural representation of the utility model supporting bracket of bridge construction.
The specific embodiment
Below in conjunction with description of drawings and the specific embodiment the utility model is further specified.
See also Fig. 1, the utility model provides a kind of supporting bracket of bridge construction 10, comprises free bearing plate 11, lower free bearing plate 13, upper chord 15, hound 17, upper high-strength split bolt 18, lower high-strength split bolt 19.Described supporting bracket of bridge construction 10 is installed on bridge pier 20, described high-strength split bolt 18, lower high-strength split bolt 19 are horizontally disposed with and are fixedly connected in the described bridge pier 20, and described high-strength split bolt 18, lower high-strength split bolt 19 connect described bridge pier 20.Described lower high-strength split bolt 19 is parallel to each other with upper high-strength split bolt 18, and in the present embodiment, described lower high-strength split bolt 19 is arranged under the described high-strength split bolt 18.
Upper free bearing plate 11 is fixedly connected on the end of described high-strength split bolt 18, and lower free bearing plate 13 is fixedly connected on the end of described lower high-strength split bolt 19.Upper free bearing plate 11, upper chord 15, hound 17, lower free bearing plate 13 are hinged successively.Described upper chord 15 is horizontally disposed with, and described hound 17 is inclined relative to horizontal.Described supporting bracket of bridge construction 10 also is provided with steel pin, and described upper chord 15 is articulated in described upper free bearing plate 11 by steel pin, and described hound 17 is articulated in described lower free bearing plate 13 by steel pin, and described upper chord 15 is articulated in described hound 17 by steel pin.In the present embodiment, upper chord 15, hound 17 adopt the Q235 steel.Upper free bearing plate 11, lower free bearing plate 13 adopt the Q345 steel.In the present embodiment, all parts is undertaken hinged by steel pin, is understandable that, also can be by other means between all parts or device carry out hingedly, do not repeat them here.
Supporting bracket of bridge construction 10 of the present utility model can be at the bridge pier 20 interior preformed holes that high-strength split bolt is set.For guaranteeing that the preformed hole position accurately is not subjected to the impact off normal in the concreting process, need at bridge pier 20 interior installation locating racks, preformed hole adopts pvc pipe.The upper free bearing plate 11 of supporting bracket of bridge construction 10 of the present utility model, lower free bearing plate 13 adopt carbon dioxide gas arc welding, and the second-order weld weldquality is good.Upper free bearing plate 11, lower free bearing plate 13 adopt high-strength split bolt to wearing bolt, and elastic deformation is effective.After carriage is removed, can be with the reserving hole channel mud jacking, the presentation quality of bridge pier 20 is good.Supporting bracket of bridge construction 10 of the present utility model is convenient to adjust spacing, is applicable to different beam types, and versatility, turnover property are strong, are applicable to the high density Construction of continuous beam, save construction cost, improve operating efficiency, reduce construction safety risk.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
