[0132] The present invention proposes a modular assembled steel-concrete composite sleeve hoop column and a connection node thereof, each part of which has a simple structure, a simple node structure, clear force transmission and convenient connection, which can effectively improve the efficiency of factory manufacturing and on-site installation.

[0133] The steel-concrete composite sleeve hoop column proposed in the present invention is divided into three parts, namely, a top column module (i.e., a beam end connection structure 3), a middle column module (i.e., an assembled steel-concrete column 2) and a bottom column module (foundation connection column 25) with independent functions, no matter how long the column is and how many floors the building has. The length of the reinforced concrete column 4 in the top column module, the bottom column module and the assembled steel-concrete column 2 does not exceed one layer, which is very suitable for factory standardization and mass production and is also convenient for transportation.

[0134] The steel-concrete composite sleeve hoop columns proposed in the present invention are all disconnected in the middle of each floor of the building (i.e., the inflection point) and inter-column connections are set. Compared with the traditional method of disconnecting at the beam-column node of each floor, they have the characteristics of simple connection force (only shear force), which is beneficial to reducing the amount of steel used in the connection node, making the inter-column connection node structure simple and efficient.

[0135] The steel-concrete composite sleeve hoop column proposed in the present invention, the connection between the beam and the column, abandons the connection method of designing an independent beam-column node, and adopts the method of integrating the beam-column node with the concrete column (that is, the steel sleeve hoop acts as the node body and is an attached part of the column itself), which effectively reduces the beam-column connection interface, thereby reducing the probability of connection failure, and speeding up the on-site connection speed. In addition, there are only two methods for the beam-column node: the middle layer beam-column node and the column top beam-column node, which is very suitable for making prefabricated standard parts with strong versatility.

[0136] The steel-concrete composite sleeve hoop column proposed in the present invention has the characteristics of ingenious and simple structure, no need for formwork, no need for steel bar binding, little wet work, and quick positioning and anchoring of the beam end. The double ear plate of the beam end connector has a vertical long circular groove, and after the position is determined by the V-shaped positioning groove on the steel sleeve hoop, the vertical long circular groove can be used to hook the rear inserted steel bar in the steel sleeve hoop, so as to achieve the effect of quick anchoring of the beam end and bearing the bending moment.

[0137] The steel-concrete composite sleeve hoop column proposed in the present invention can form different types of column base anchoring connections by simply replacing different types of column base connectors (i.e., the integrated column base connector disclosed in Example 13, the separate column base connector disclosed in Example 15, and the embedded column base connector disclosed in Example 16). The column base is connected to a fully exposed column base through an integrated column base connector, to a semi-exposed column base through a separate column base connector, and to an embedded column base through an embedded column base connector. In this way, a set of columns can be effectively adapted to different column base installation environments. For the embedded column base, the bottom steel sleeve hoop of the bottom column can be directly inserted into the post-casting cup formed by the embedded column base connector to form a whole with the foundation, which has the characteristics of simple structure, fewer processes, pure dry connection, and quick assembly.

[0138] The modular assembled steel-concrete composite sleeve hoop column of the present invention can effectively solve the technical problems of excessive deadweight of traditional single PC columns, low degree of standardization, and inconvenient assembly method, while also solving the technical problems of high cost of steel columns, large anti-corrosion and fireproof maintenance area, and easy instability under pressure.

[0139] Finally, it should be noted that the above embodiments are only preferred embodiments of the present invention to illustrate the technical solution of the present invention, but not to limit it, and certainly not to limit the patent scope of the present invention. Any changes or modifications that have no substantial significance on the main design concept and spirit of the present invention, which solve technical problems consistent with the present invention, should be included in the protection scope of the present invention; in addition, the direct or indirect application of the technical solution of the present invention in other related technical fields should also be included in the patent protection scope of the present invention.
