[0002] The concrete column joint unit is a kind of prefabricated component widely used in modern building structure, mainly by prefabricated concrete column, connecting bar (such as steel pipe body or steel plate) and the reinforcing steel or positioning bar for connecting these components etc. The design of this joint unit aims to provide longitudinal and lateral support for building structure, so that it maintains stability and safety under various external forces. The concrete column joint unit plays a vital role in building structure, not only supports the weight of building, but also helps to transfer and disperse the power from external environment, such as wind force, earthquake force and other dynamic load. By optimizing the design of these nodes, engineers can ensure that the building remains stable and safe under extreme conditions, thereby improving the seismic and wind resistance of the building. In addition, due to the modular nature of these joint units, the construction process is simplified and accelerated, and the use of prefabricated components reduces the need for site pouring of concrete, thereby avoiding the influence of weather changes and reducing construction time and labor cost. Construction personnel can quickly install these concrete column joint units in place and quickly complete the assembly of the overall structure.

[0003] However, the conventional prefabricated concrete column component joint unit is often difficult to accurately butt joint the upper and lower nodes due to the weight and size of the prefabricated component when connecting up and down, which may lead to inaccurate installation and affect the stability of the overall structure. Moreover, the design of the connection often cannot effectively resist shear force, especially under the action of strong earthquake or wind load, which may cause slippage or damage at the connection and affect the safety of the structure.

[0004] Therefore, the skilled in the art provides a kind of fabricated concrete column joint unit to solve the problems raised in the above background art. SUMMARY

[0005] The utility model aims at solving the shortcomings in the prior art and provides a kind of fabricated concrete column joint unit. The new model strengthens the shear resistance of the joint from the structure, ensures more convenient construction and more accurate positioning.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions:

[0007] The utility model provides a kind of fabricated concrete column joint unit, including four lower layer prefabricated concrete columns, four upper layer prefabricated concrete columns, four steel pipe bodies and four prefabricated concrete beams, and steel pipe sleeve is movably arranged in the hole of the opposite end of two two of the four lower layer prefabricated concrete columns and four upper layer prefabricated concrete columns, and node steel plate is fixedly arranged at the opposite end of multiple steel pipe sleeves, and channel steel is fixedly arranged at the lower end of the both sides of four prefabricated concrete beams.

[0008] Further, the four lower layer prefabricated concrete columns and the four upper layer prefabricated concrete columns are in the same pattern, and the four lower layer prefabricated concrete columns and the four upper layer prefabricated concrete columns are in the form of L-shaped columns, T-shaped columns, square columns and rectangular columns.

[0009] Further, the four lower layer prefabricated concrete columns are fixedly connected with the four prefabricated concrete beams, and the four steel pipe bodies are fixedly connected with the multiple node steel plates.

[0010] Further, the four upper layer prefabricated concrete columns are movably arranged on the upper ends of the four lower layer prefabricated concrete columns.

[0011] The utility model has the following beneficial effects:

[0012] The fabricated concrete column joint unit disclosed by the utility model is buried in the upper and lower layer prefabricated concrete columns by 1 / 6 when processed in a processing factory, and the node steel plate is welded and fixed to the end of the steel pipe sleeve. When installed, the lower layer prefabricated concrete column is fixed with the prefabricated concrete beam, and then the positioning steel pipe body is inserted into the lower layer column, which facilitates the on-site installation and positioning, enhances the shear resistance of the joint, optimizes the stress distribution, effectively disperses stress through the unique column design when the structure is subjected to external loads such as wind and earthquake forces, thereby enhancing the seismic capacity of the entire building. Through the optimization of stress design, the safety performance of the building under extreme conditions can be improved, and the potential damage risk can be reduced. The connection mode of the utility model strengthens the shear resistance of the joint from the structure, and compared with the traditional connection mode, the connection part is prone to weakness when bearing shear force, but the utility model adopts the design of welding and combining with the steel pipe body, which can significantly improve the strength of the overall joint, so that it still maintains good stability under high load. In addition, the combination of prefabricated concrete and steel pipe body reduces the demand for site pouring of concrete, reduces human errors in the construction process and the need for later maintenance. Furthermore, the accurate reserved hole and welding position ensure the accuracy of positioning during installation, further improving the construction efficiency. BRIEF DESCRIPTION OF DRAWINGS
