Abstract
The utility model discloses a kind of overcasts, including concrete strip footing, column, stringer, crossbeam and table-top；The cast-in-place molding of concrete strip footing, column stand in concrete strip footing, fix with the built-in fitting in concrete foundation；Stringer is longitudinally placed in column top surface, and is welded and fixed；Crossbeam is laterally placed on stringer, is equally welded and fixed；It is laid with steel plate at the top of crossbeam, steel plate is fixed with beam welding.The overcast, at the top of construction working platform, worker can be located at workbench on construct, facilitate the construction of bridge.Meanwhile the door opening formed below column, vehicle pass-through can be convenient for, can be reduced the influence current to existing road.
Description
Technical field
The utility model relates to the overcast structures that construction of railways uses.
Background technique
During bridge construction, it can encounter and need the case where crossing over existing road.In order to not influence the passage of road, can take
If rack platform, the direct assembling construction on platform can construct in the case where not influencing original road.Subtract
Shaoshi work influences current bring.
Summary of the invention
The utility model is directed to that existing road can be not being influenced, and can facilitate and realize the aerial of bridge construction
Supporting structure.
Overcast described in the utility model, including concrete strip footing, column, stringer, crossbeam and workbench；The concrete
The cast-in-place molding of strip footing, column are stood in concrete strip footing, are fixed with the built-in fitting in concrete foundation；Stringer is longitudinally placed in vertical
Capital face, and be welded and fixed；Crossbeam is laterally placed on stringer, is equally welded and fixed；Crossbeam top be arranged workbench,
Workbench is fixed with beam welding.
The overcast, top are the workbench of construction, and worker, which can be located on workbench, to construct, and facilitates bridge
Construction.Meanwhile the door opening formed below column, vehicle pass-through can be convenient for, can be reduced the influence current to existing road.
Detailed description of the invention
The structural schematic diagram of Fig. 1 overcast described in the utility model；
The structural schematic diagram of Fig. 2 overcast described in the utility model；
The structural schematic diagram of Fig. 3 pre-buried connector.
Specific embodiment
A kind of overcast, as shown in Figure 1, Figure 2, including concrete strip footing 1, column 2, stringer 3, crossbeam 4 and table-top
5；The concrete strip footing is poured using excavated by manual work foundation pit, keeps strip footing top surface concordant with earth's surface absolute altitude, with C25 concrete it is cast-in-place at
Type.In order to ensure the stabilization of steel pipe post, the built-in connection at the top of concrete strip footing is connected by pre-buried connector and column
It connects.
The pre-buried connector 6 welds the reinforcing bar 62 of lower extension, steel plate including steel plate 61, steel plate bottom such as Fig. 3
Top the steel pipe 63 that upwardly extends is set, on steel pipe top, connecting flange 64 is set.
The settable upward hook portion 65 of the reinforcing bar of connector bottom, can further increase connector and concrete strip footing it
Between link stability, the also further fastness improved after connection column.
Column can be spliced according to length by one or more steel pipe post, and steel pipe post is fixed each other by flange, bottom
Flange is equally arranged in the bottom of the steel pipe post in portion, passes through the flanged joint at the top of flange and pre-buried connector flange.
The longitudinally disposed I-shaped steel longitudinal beam in the top of steel pipe post, stringer are welded and fixed with column, are arranged again at the top of stringer horizontal
To I-shaped gooseneck, I-shaped gooseneck is welded and fixed with I-shaped steel longitudinal beam.
The welding bench on I-shaped gooseneck.When construction, worker can operate on the table, convenient and safe, and not shadow
Ring the traffic of existing line.
Stud materials use 630 × 10mm of Ф steel pipe, using segmented assembly, ring flange are all arranged up and down in steel pipe, leads to
It crosses to be bolted and carrys out spreading.Using steel plate as cover board at the top of column.
Column has more, is connected between adjacent steel column with channel steel, enhances the horizontal and vertical stability of steel pipe column.Stringer is adopted
With Three kinds of hors d'oeuvres I-steel.Stringer and existing road axes are at angle.Stringer Three kinds of hors d'oeuvres I-steel is connected using anchor ear form.
