Description

Technical Field

[0001] The utility model relates to the technical field of building construction devices, in particular to a reinforced concrete assembled cantilevered plate structure. Background Art

[0002] Reinforced concrete cantilever slab structure is a formwork combination structure used for pouring concrete cantilever beams. Traditional cantilever slabs are mainly composed of seven parts: U-shaped cone ring, wire rope, side plate, bottom plate, support column, tension bolts and wire rope clamp. With the development of science and technology, there are more and more types of reinforced concrete cantilever slab structures, and the demand for reinforced concrete cantilever slab structures is getting higher and higher.

[0003] Most existing cantilever slab structures are fixed, which is not convenient for installation and fixation of buildings of different heights. Moreover, the external cantilever slab is too long and difficult to fix, which can easily cause construction accidents and affect the construction progress. There is no support under part or all of the building, which gives people a sense of instability, mainly due to lateral force. Different from suspension, when the concrete cantilever of a building is constructed, it is often necessary to use concrete formwork for support before concrete pouring can be carried out. The concrete formwork can be removed after the concrete solidifies. The cantilever concrete formwork needs to be supported by a support device during construction to ensure that it will not collapse when pouring concrete.

[0004] After searching, the applicant found that a Chinese patent disclosed "a reinforced concrete cantilever beam formwork structure", and its publication (announcement) number is "CN 206636216 U". This patent mainly connects the angle steel with the U-shaped cone ring through a conical nut, the steel wire rope passes through the upper clamp and the lower clamp and is connected to the wire rope clamp, the support column is connected to the bottom plate, and the side plate is provided with standoff steel bars. The reinforced concrete cantilever beam formwork structure is innovatively designed in combination with the currently used reinforced concrete cantilever beam formwork structure. The reinforced concrete cantilever beam formwork structure fixes the I-beam by pre-embedded U-shaped cone rings, and cooperates with the bottom support columns to well solve the problem of difficult cantilever beam support. Not only does it not have safety hazards and high costs, it can also greatly shorten the construction period. A plywood module consisting of an upper plywood and a lower plywood is arranged on the upper and lower sides of the side panels, which can well fix the cantilever beam in a specified position and is not prone to misalignment. However, the device is not convenient for fixing and adjusting according to the height of different floors, which affects the progress of construction. For this reason, we propose a reinforced concrete assembled cantilever plate structure. Utility Model Content
