Mould platform is hung in a kind of steel truss girder concrete slab construction
Technical field
The utility model belongs to steel truss girder concrete slab laying technology field, particularly relates to the construction of a kind of steel truss girder concrete slab and hangs mould platform.
Background technology
In steel truss girder concrete-bridge building course, bridge deck are laid is vital part in work progress after steel truss girder is built, its difficult problem is how to guarantee steel work producing balanced forces in casting process, steel work is avoided to produce local inhomogeneous deformation, cause the change of bridge force-bearing model, bridge deck concrete is caused to ftracture, produce quality accident, even structure is overturned, in practice of construction, unit in charge of construction is through repeatedly studying demonstration, finally determine that employing is hung modulus method and built bridge deck, the modulus method that hangs conventional at present adopts the suspension bracket be covered with at steel truss girder upper surface, refer to Fig. 5, the laying lumps of wood is carried out in the below of suspension bracket, bamboo slab rubber, and then carry out concreting, although this kind of mode solves the construction method of original full framing, decrease the turnover of material and artificial consumption, but need after laying by the angle bar frame being welded on steel truss girder upper surface one by one sawing fall, part angle steel is left in concrete after sawing, then repair one by one, workload is added in the middle of invisible like this, because upper surface lays suspension bracket, by the restriction in space when laying the lumps of wood in practice of construction process, laying the lumps of wood can only insert from suspension bracket one end, so greatly reduces operating efficiency.
Summary of the invention
The utility model provides the steel truss girder concrete slab construction that is simple, easy to install, that increase work efficiency of a kind of structure to hang mould platform for solving in known technology the technical problem that exists.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
Mould platform is hung in a kind of steel truss girder concrete slab construction, comprise the array horizontal tray between fixed installation girder, often organize horizontal tray comprise be arranged in parallel truss girder, the same side, both ends of described truss girder is provided with peg, the upper end of described peg is provided with horizontal bending laterally, described horizontal bending part is mounted on girder upper surface, and welds together with girder upper surface.
The utility model can also adopt following technical measures:
The same side, both ends of described truss girder is welded with center sleeve, and described peg is inserted in described center sleeve, and the bottom of described peg is provided with thread segment, and described thread segment stretches out the lower surface of center sleeve, equipped adjusting nut and pad on thread segment.
Described truss girder is embedded with bubble and scale.
The advantage that the utility model has and good effect are: because the utility model adopts said structure, namely adopt and hang mould platform in the soffit laying of steel truss girder, the application of this kind of structure instead of the construction method of existing over sling, ensure that steel truss girder hangs steel truss girder producing balanced forces in mould putting up platform, concreting process, distortion is symmetrical, even, only by sawing peg, need reserve within it after sawing, need not repair in the later stage after having built; Owing to there is no other component interference hanging above mould platform, thus the laying lumps of wood and bamboo slab rubber convenient and swift; Decrease turn around time and the manual application amount of material simultaneously, shorten the duration, reduce construction cost and achieve good economic benefit; And less to the traffic impact of steel truss girder upper surface in practice of construction process, do not affect normally carrying out of other operation.

Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Embodiment 1, refer to Fig. 1 and Fig. 2, mould platform is hung in a kind of steel truss girder concrete slab construction, comprise the array horizontal tray 1 between fixed installation girder, often organize horizontal tray comprise be arranged in parallel truss girder 1-1, the same side, both ends of described truss girder is welded with peg 1-2, and the upper end of described peg is provided with horizontal bending 1-20 laterally, described horizontal bending part is mounted on girder upper surface, and welds together with girder upper surface.
Embodiment 2, refer to Fig. 3, in order to improve the levelness adjusting the lumps of wood after laying the lumps of wood, center sleeve 2 is welded with in the same side, both ends of described truss girder, described peg is inserted in described center sleeve, the bottom of described peg is provided with thread segment 1-21, and described thread segment stretches out the lower surface of center sleeve, equipped adjusting nut 3 and pad 4 on thread segment.All the other features are identical with embodiment 1.
Embodiment 3, refers to Fig. 4, in order to improve the levelness of truss girder further, described truss girder is embedded with bubble and scale 5, like this can directly by the Realize of the direct reaction bracket beam of bubble and scale.All the other features are identical with embodiment 2.
Adopt said structure, namely adopt and hang mould platform in the soffit laying of steel truss girder, the application of this kind of structure instead of the construction method of existing over sling, ensure that steel truss girder hangs steel truss girder producing balanced forces in mould putting up platform, concreting process, distortion is symmetrical, even, only by sawing peg, need reserve within it after sawing, need not repair in the later stage after having built; Owing to there is no other component interference hanging above mould platform, thus the laying lumps of wood 7 and bamboo slab rubber 8 convenient and swift; Decrease turn around time and the manual application amount of material simultaneously, shorten the duration, reduce construction cost and achieve good economic benefit; And less to the traffic impact of steel truss girder upper surface in practice of construction process, do not affect normally carrying out of other operation.
The above is only to preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
