Description

Novel matching beam anti-sliding structure

Technical Field

The utility model relates to a novel matching beam anti-sliding structure, in particular to the technical field of bridge construction industry.

Background

At the present stage, road construction in China is found very quickly, and the conventional common bridge construction mode is site pouring. With the continuous development of cities, construction of each component of a bridge in a cast-in-place manner in an urban area is increasingly limited by the requirements of the surrounding environment and construction conditions. Therefore, the full-prefabricated production mode of a bridge component factory is more and more widely applied, and the prefabricated capping beam is a main prefabricated component in a full-prefabricated assembled bridge. Capping refers to a beam placed on top of the bent pier to support, distribute and transfer the load of the superstructure. Also known as a hat beam. The bridge pier (platform) or the row pile is provided with a beam made of reinforced concrete or less reinforced concrete. The main function is to support the bridge superstructure and transfer all loads to the substructure.

When the segmental beams are matched, the matched beams can be subjected to concrete side pressure of the poured beams. At present, when pouring is carried out, lateral pressure borne by a matching beam is offset by the anti-sliding of the matching beam only through friction force between a supporting leg foot of a bottom die of the matching beam and the bottom die, but when the friction force is smaller than the lateral pressure of concrete, the matching beam can slide, so that large errors are generated in beam length, and particularly when the condition is generated in adjustment of a section, the whole collapsed length can be affected, and the construction difficulty in girder erection is increased.

With respect to the segmental beams, when matched, the matched beams are subjected to concrete side pressure of the poured beams. At present, when pouring is carried out, lateral pressure borne by a matched beam is offset by anti-sliding of the matched beam only depending on friction force between a supporting leg foot of a bottom die of the matched beam and the bottom die, but when the friction force is smaller than the lateral pressure of concrete, the matched beam can slide, so that large errors are generated in beam length, and particularly when the condition is generated in adjustment of a section, the overall collapsed length can be affected, and the problem of construction difficulty in beam erecting is solved. In chinese patent publication no: CN 211736652U discloses a temporary protection frame suitable for a prefabricated section matching box girder, the technical scheme comprises a main frame and a main board, the technical scheme utilizes a hoisting point hole on the section matching box girder to install the protection frame, other devices do not need to be welded or drilling holes do not need to be drilled, the main frame and the main board can be disassembled, and the main board can be folded through hinges, so that the carrying and the installation are convenient; however, the problem that the matching beam slips during pouring provided by the utility model cannot be solved by the technical scheme.
