Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a complete supporting device of an ultra-large span concrete structure which can be dismantled early. Background Art

[0002] When constructing the floor structure in a building project, it is necessary to support the formwork and support system. After the concrete strength reaches the design requirements, the formwork and support system will be removed. In addition to the concrete design strength, the removal conditions are related to the span of the component. When the component span is ≤2m, it will be removed when the design concrete strength grade value is ≥50%; when the component span is >2m and ≤8m, it will be removed when the design concrete strength grade value is ≥75%; when the component span is >8m, it will be removed when the design concrete strength grade value is ≥100%. Conventional formwork and brackets need to reach 100% before they can be removed. The early formwork removal technology uses the time difference between removing the formwork when it reaches 100% and removing the formwork when it reaches 50% or 75%, realizing the early removal of the bottom formwork and its support system. As a technical measure to accelerate the turnover of the formwork and reduce the investment in the formwork, it is also a measure to reduce costs and speed up the construction speed. It also reflects the advanced nature of the formwork and its support system. The early removal head is the core of the entire early removal device and is one of the important components for realizing early removal of the formwork.

[0003] For example, the Chinese utility model patent with the announcement number CN204081477U discloses an early disassembly device, including a lead screw and a top plate, a clamp, a bracket and an adjustment handle arranged on the lead screw in sequence, wherein: the plate surface boundary line of the top plate is a smooth curve, and the top plate is fixedly connected to the end of the lead screw; the bracket is sleeved on the lead screw, and the bracket can move along the axial direction of the lead screw; the clamp is fixedly installed on the lead screw and is used to limit the movement of the bracket; the adjustment handle is set to two, and the two adjustment handles are respectively screwed on the lead screw;

[0004] The above scheme has the following problems: the early dismantling device provided by the device during use can avoid the situation of empty top of the roof, thereby reducing the accident rate of construction, and has the characteristics of easy operation, good stability and high safety. However, the device cannot ensure that the supporting structure can obtain good strength during use, and cannot improve the turnover rate of the supporting device, so that the turnover of materials used in construction is too slow, affecting the work progress.
