Description

Technical Field

[0001] The utility model relates to the technical field of installation of superimposed plates, in particular to a device for reinforcing and leveling superimposed plates. Background Art

[0002] As a green and environmentally friendly structural form, prefabricated concrete structures are currently widely promoted and applied in my country. As the main component of prefabricated concrete structures, the installation and leveling of the composite slabs must be designed and constructed in accordance with relevant specifications. However, during the specific construction on site, due to the actual situation of the construction site, the composite slabs are inevitably tilted during the installation process, and the manual prying during the leveling of the composite slabs can easily damage the sponge rubber strips. Unqualified leveling can also lead to a large gap between the composite slabs and the formwork, the rubber strips cannot be fully sealed, the support and reinforcement of the formwork at the plate strip position is not in place, and the formwork is deformed after pouring concrete, resulting in leakage. Excessive force on one side can easily cause the composite slabs to crack or even break, which will seriously affect the quality of the project. The existing construction process basically controls the wire rope of the hoist and manually pries the composite slabs during leveling. There is no convenient and effective method for leveling and checking the composite slabs, and accurate leveling methods are still a vacuum area. Utility Model Content
