Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a connection structure between a lifting frame and an independent column. Background Art

[0002] Independent columns are being widely used as vertical load-bearing components of buildings, bridges, and structures. During the construction of independent columns, it is usually necessary to first tie the longitudinal reinforcement and stirrups at the construction site to form a steel cage, then set up the outer formwork, pour and cure concrete, and remove the formwork after the concrete reaches a certain strength to complete the forming of the independent column. Due to the inconvenience of high-rise building construction, some independent columns need to be lifted to the installation position by a lifting frame after being cast on the ground for installation.

[0003] At present, the lifting of independent columns is generally done by pre-embedding anchor plates on the independent columns, setting anchor bars on the bottom of the anchor plates and embedding them in the concrete independent columns, and welding and fixing the lifting frame to the anchor plates. After the lifting work is completed, the lifting frame and the anchor plates are separated by cutting and the lifting frame is removed. However, there are raised parts on the plane of the anchor plates, which need to be polished and made smooth, which is a more troublesome operation. Summary of the invention

[0004] In view of this, the purpose of the utility model is to provide a connection structure between a lifting frame and an independent column, to improve the work efficiency of the connection and fixation between the lifting frame and the independent column, to avoid the high temperature of welding affecting the concrete independent column structure, and at the same time, the embedded plate is not damaged and remains in its original state, saving labor costs.

[0005] The connection structure between the lifting frame and the independent column provided by the utility model adopts the following technical solutions:

[0006] A connection structure between a lifting frame and an independent column, comprising a lifting frame bottom plate arranged on the lifting frame and an embedded plate embedded in the top of the independent column, the lifting frame bottom plate abuts against the embedded plate, a plurality of connecting sleeves are vertically arranged on the embedded plate, the top of the connecting sleeve is flush with the top surface of the embedded plate and the bottom extends into the independent column, a plurality of connecting screws corresponding to the connecting sleeves are arranged on the lifting frame bottom plate, the connecting screw passes through the lifting frame bottom plate and is inserted into the connecting sleeve and is threadedly matched with the connecting sleeve, a fixing nut is threadedly sleeved on one end of the connecting screw located on the lifting frame bottom plate, and the fixing nut abuts against the lifting frame bottom plate.

[0007] Furthermore, a reinforcement plate is provided at the bottom of the connecting sleeve.

[0008] Furthermore, two fixing nuts are provided and are overlapped and sleeved on the connecting screw.

[0009] Furthermore, the connecting sleeves are evenly distributed on the embedded plate, and a plurality of through holes corresponding to the connecting sleeves are evenly arranged on the bottom plate of the lifting frame.

[0010] Furthermore, a bayonet for rotation is provided at the top end of the connecting screw.

[0011] Furthermore, the area of ​​the bottom plate of the lifting frame is the same as the area of ​​the embedded plate, and the bottom plate of the lifting frame is completely fitted and fixed to the embedded plate.

[0012] In summary, the utility model includes at least one of the following beneficial effects: the embedded plate is embedded in the concrete, and the internal thread connecting sleeve is set and connected and fixed with the lifting frame by screws to achieve the lifting working conditions, avoiding the influence of welding fixation on the quality of the concrete.
