Description

The pre-assembled moulding bed of large sections steel box-girder
Technical field
The utility model relates to a kind of steel box girder assembling equipment, particularly relates to a kind of large pre-assembled moulding bed of sections steel box-girder.
Background technology
Steel box-girder is the form of structure that Large Span Bridges is conventional, is generally formed by connecting by all-welded mode by top board, base plate, back and diaphragm, midfeather and stiffening rib etc.Traditional erection method generally carries out in outdoor, each sections of steel box-girder is transported to job site, after carrying out welding assembly at the scene, then be arranged on bridge pier, but due to the size of steel box-girder general larger, welding job amount in erecting bed is very large, the impact that outdoor work keeps environmental factor and weather is also larger, and a large amount of welding job needs to complete in the air at height, there is high risk factor, there is no reliable positioning equipment when installing simultaneously, easily occur dislocation metaboly.
Utility model content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, provides the pre-assembled moulding bed of large sections steel box-girder that a kind of structure is simple, easy to use, conveniently can regulate steel box-girder camber.
The technical scheme that the utility model adopts is: the utility model comprise some be fixedly connected on ground built-in fitting moulding bed column, be connected to the connection system between two adjacent described moulding bed columns and be fixedly installed on the moulding bed crossbeam on described moulding bed column top, described moulding bed crossbeam is also fixedly installed adjustment steel plate, the position, rear and front end below described moulding bed crossbeam is all reserved with beam transporting passage.
Often be provided with two described connection systems between adjacent two described moulding bed columns, two described upper ends connecting system are all fixedly installed on described moulding bed crossbeam, and the other end is then fixed therein on a described moulding bed column.
Preferably, with bolts between described connection system and described moulding bed column.
The beneficial effects of the utility model are: due to the utility model comprise some be fixedly connected on ground built-in fitting moulding bed column, be connected to the connection system between two adjacent described moulding bed columns and be fixedly installed on the moulding bed crossbeam on described moulding bed column top, described moulding bed crossbeam is also fixedly installed adjustment steel plate, the position, rear and front end below described moulding bed crossbeam is all reserved with beam transporting passage.Compared with prior art, the utility model is by the moulding bed of described moulding bed column, described moulding bed crossbeam and described connection system composition, realize location during steel box girder assembling, and can be realized the adjustment of steel box-girder camber by described adjustment steel plate, arranging of described beam transporting passage can allow dolly enter and steel box-girder is transported out of the utility model.So the utility model structure is simple, easy to use, can conveniently regulate steel box-girder camber.
Due to bolts between described connection system and described moulding bed column.Formed almost by bolted mode between the utility model each several part, easy accessibility, existing with existing dress, effectively reduce the occupancy of job site.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model comprise somely be fixedly connected on the moulding bed column 1 of ground built-in fitting, the connection be connected between two adjacent described moulding bed columns 1 is 2 and is fixedly installed on the moulding bed crossbeam 3 on described moulding bed column 1 top, described moulding bed crossbeam 3 is also fixedly installed and regulates steel plate 4, the position, rear and front end below described moulding bed crossbeam 3 is all reserved with beam transporting passage 5.
Often being provided with two described connections between adjacent two described moulding bed columns 1 is 2, two described connections be 2 upper end be all fixedly installed on described moulding bed crossbeam 3, the other end is then fixed therein on a described moulding bed column 1.Described connection is with bolts between 2 and described moulding bed column 1.
When large sections steel box-girder carries out assembled, first described moulding bed column 1 is welded on the ground built-in fitting burying in advance and put well, then is 2 moulding bed column 1 described in each to be coupled together by described connection, form a moulding bed similar to steel box-girder size.Then described moulding bed crossbeam 3 in the welded top of described moulding bed column 1, and described adjustment steel plate 4 is placed with on described moulding bed crossbeam 3, by the camber of described adjustment steel plate 4, realize the adjustment of steel box-girder camber.Position, described moulding bed rear and front end is also reserved with beam transporting passage 5, after steel box girder assembling terminates, remove the described moulding bed crossbeam 3 on described beam transporting passage 5 position, fortune beam dolly is after from then on position enters, remove the connection between this moulding bed and steel box-girder, utilize the jacking ability of fortune beam dolly self, steel box-girder top is transported after the utility model.Because the connection between described moulding bed column 1 is all with bolts, therefore moulding bed can be removed rapidly after using.
The utility model is applicable to bridge construction field.
