Description

Technical Field

[0001] The utility model relates to the technical field of hollow slab jacking, in particular to a hollow slab jacking device. Background Art

[0002] In bridge construction projects, the use of prefabricated concrete installation construction methods has accelerated the speed of project construction. The main load-bearing structural member of the bridge - hollow slab, has good force performance and saves materials. It is the most economical load-bearing component of the bridge. Bridge hollow slabs are also commonly called prefabricated bridge slabs, prestressed bridge slabs, bridge prefabricated hollow slabs, etc. According to the cross-sectional form, they are divided into hollow slab beams, box beams, T-beams, etc., which are the upper components of bridges made of reinforced concrete. The main function is to support the bridge deck load and transfer all loads to the lower structure. In recent years, my country's highway transportation industry has developed rapidly, and more and more highway bridges use prefabricated prestressed concrete hollow slabs.

[0003] During the construction of a bridge, multiple hollow slabs are usually laid in sequence by hoisting, and the specific number is determined by the width of the bridge deck; the multiple hollow slabs are spliced ​​with hinged joints; however, when the hollow slabs are laid, after the multiple hollow slabs are spliced ​​with hinged joints, they often tilt to the side. Therefore, it is urgent to push the hollow slabs to adjust the angles of the multiple hollow slabs. Utility Model Content

[0004] In view of the above problems existing in the prior art, the technical problem to be solved by the utility model is that when the hollow slabs are laid, after multiple hollow slabs are spliced ​​with hinged seams, they often tilt to the side.

[0011] Preferably, the pushing mechanism is provided with a plurality of them in the length direction of the pushing plate, so as to provide thrust for the pushing plate uniformly.

[0012] Preferably, the telescopic member is a synchronous jack. The provision of the synchronous jack overcomes the problem that a single jack is prone to tilting when lifting a heavy object, which may damage the object and cause danger.

[0013] Preferably, the push plate is provided with a plurality of insertion holes spaced apart in the length direction thereof, and bolts are inserted into the hollow plate through the insertion holes, thereby installing the push plate on the hollow plate.
