fig. 1A shows a side view of a steel-reinforced concrete structural rectangular column 100 (hereinafter simply referred to as rectangular column 100) according to an embodiment of the present invention; 3 FIG. 3 1 3B 3 shows 3a 3 cross 3- 3 sectional 3 view 3 taken 3 along 3 section 3 line 3A 3- 3A 3 of 3 the 3 steel 3- 3 concrete 3 structural 3 rectangular 3 column 3 100 3 of 3 FIG. 3 1 3A 3; 3 Fig. 1C shows a view of a cross section taken along section line B-B of the steel-reinforced concrete structural rectangular column 100 in fig. 1A.

referring to fig. 1A, the rectangular column 100 includes a reinforced concrete column 300, and steel columns 200 at both ends of the reinforced concrete column 300. Referring to the sectional views of fig. 1B and 1C, the reinforced concrete column 300 and the steel column cap 200 of the rectangular column 100 are both rectangular in cross section.

The internal structure of cylinder 300 is shown in the cross-sectional view of FIG. 1B. Specifically, in the illustrated embodiment, the column 300 includes angle irons 301 at four corners of the column 300, a plurality of longitudinal load-bearing rebars 302 arranged along a circumference of the column 300, and concrete 303 filling a majority of the structure of the column. The angle steel 301 disposed at the corner of the column body 300 is connected (e.g., bolted, or welded) to the steel column head 200, facilitating the pouring of concrete, and particularly, facilitating the maintenance of dimensional accuracy of the column body 300 in the longitudinal direction (i.e., the vertical direction in the view of fig. 1A) during the pouring of concrete. The circumferentially arranged longitudinal force-bearing rebars 302 help to maintain the strength of the column structure. Only the right four longitudinal force-receiving rebars 302 are labeled in fig. 1B, but it should be understood that the longitudinal force-receiving rebars are arranged along the entire circumference of the column 300, and there are 12 longitudinal force-receiving rebars in the embodiment of fig. 1B for reinforcing the entire strength of the column 300. It should be understood by those skilled in the art that although 12 longitudinal force-receiving rebars arranged along the circumference of the column 300 are shown in the embodiment of fig. 1B, those skilled in the art may increase or decrease the number of longitudinal force-receiving rebars or add longitudinal force-receiving rebars to the central portion of the column 300 on the basis of the national standard. In a preferred embodiment, a plurality of longitudinally disposed longitudinally stressed steel bars 302 are secured by stirrups and lashed thereto to help maintain the position and shape of the longitudinally stressed steel bars during the casting of the concrete.

The internal structure of the steel column head 200 portion is shown in the cross-sectional view of FIG. 1C. Specifically, the steel stud 200 partially includes a rectangular steel tube 201. The longitudinal force-bearing reinforcing bars 302 extend in the longitudinal direction of the rectangular column 100, through the entire column body 300, and preferably through the entire steel column head 200 provided at both ends. Rectangular steel tubes 201 are arranged along the circumference of the steel stud 200 and are used for mating connection with steel nodes (shown in fig. 5 below).

The steel-reinforced concrete structural rectangular column 100 is prefabricated in a factory. Specifically, rectangular steel pipes 201 at the upper and lower ends, steel diaphragms (not shown), angle steel 301, longitudinal load-bearing steel bars 302, and stirrups are first connected (e.g., by bolting) at the factory into a structurally stable rectangular column steel skeleton 100' (excluding concrete). Fig. 2A shows a side view of a rectangular column steel skeleton 100' (i.e., a state where the steel-concrete structure rectangular column 100 is not concreted). As can be seen more particularly in fig. 2A, the longitudinal force-bearing rebar 302 extends along the longitudinal direction, along the entire length of the reinforced-concrete-structure rectangle 100. Subsequently, on the work bench, the rectangular column steel skeleton 100' is supported by using a standard steel formwork, and concrete is poured to form the steel-reinforced concrete structure rectangular column 100 as shown in fig. 1A. The steel-reinforced concrete structural rectangular column 100 is provided with the steel studs 200 only at both ends thereof, and thus corresponds to only a single floor, and thus is referred to herein as a single-layered steel-reinforced concrete structural rectangular column.

Fig. 2B shows a side view of a rectangular steel pipe 201 (in a state where concrete is not poured) of the steel stud. Fig. 2C shows a top view of the rectangular steel tube 201 of fig. 2B, showing a view of the upper surface of the end spacer 202. Fig. 2D shows a view from above looking down, taken along section line C-C, showing a view of the upper surface of the middle baffle 204. In the rectangular column steel skeleton 100' shown in fig. 2A, longitudinal force-receiving rebars 302 are connected (e.g., bolted) to the end bulkheads 202 of the rectangular steel pipes 201 through the holes 205 in the center bulkheads 204 of the rectangular steel pipes 201, through the holes 203 in the end bulkheads 202. The end spacers 202 and the intermediate spacers 204 and the holes in them effectively fix the position of the longitudinal load bar 302. The end partition 202 and the middle partition 204 of the rectangular steel pipe 201 can fix the position of the longitudinal stress steel bar 302 better, and particularly avoid deformation at the head of the steel column, so as to facilitate connection with a matched steel node. In a preferred embodiment, the midplate 204 is configured as a rectangular plate and has a hollow portion. The rectangular steel pipe 201 is fixed to the angle iron 301 through a hole provided on the sidewall, thereby being connected to a portion of the rectangular column steel skeleton 100' corresponding to the column 300 (fig. 1A). It should be understood by those skilled in the art that although only the rectangular steel pipe 201 disposed at the upper end portion is illustrated in fig. 2A-2D, the rectangular steel pipe 201 disposed at the lower end portion has a similar structure and connection, and thus, a detailed description thereof is omitted.

Fig. 3A shows an assembled structure of two rectangular columns 100A, 100B connected together in a vertical direction by a steel node 500, in which the outer surfaces of the rectangular steel pipes of the steel column heads 200A, 200B are shown by dotted lines. Fig. 3B shows the skeletal structure of rectangular columns connected together by steel nodes 500 to more clearly illustrate the mating relationship of the steel nodes 500 and the rectangular columns 100A, 100B.

referring specifically to fig. 3A, the two rectangular columns are labeled as upper rectangular column 100A and lower rectangular column 100B, respectively. The rectangular posts 100A, 100B in fig. 3A are identical in structure to the rectangular post 100 in fig. 1A, with their respective components respectively affixed with a suffix A, B for ease of description and differentiation. A steel stud 200A at the lower end of the upper rectangular column 100A and a steel stud 200B at the upper end of the lower rectangular column 100B are inserted into the steel node 500. The outer surface of the steel node 500 has substantially the same size as the outer surface of the reinforced concrete column 300, so that a substantially flat outer surface is formed after the steel node 500 is completely assembled with the rectangular columns 100A, 100B, contributing to an aesthetic appearance and reducing subsequent operations. The gaps between the outer surfaces of the steel column heads 200A, 200B and the inner surfaces of the steel nodes 500 are filled with a high-strength caulking material. The high-strength caulking material preferably uses epoxy resin, and more particularly uses a material suitable for connecting steel materials. The high-strength gap filling material can effectively ensure the fixed connection between the rectangular steel pipe of the steel column head and the steel node 500, and simultaneously fill the gap between the outer surfaces of the steel column heads 200A and 200B and the inner surface of the steel node 500, thereby compensating the machining error possibly generated in the machining process, reducing the machining precision requirement of components and being beneficial to the installation of the components.

fig. 4 shows a top view of the steel node 500 of fig. 3A-3B. In this exemplary embodiment, the steel node 500 is used only to connect two vertically arranged rectangular columns 100A, 100B, without connecting any beams. The steel node 500 is formed as a rectangular steel tube structure and its hollow portion is adapted to receive the steel studs 200A, 200B. The size of the inner surface of the steel node 500 is equal to or slightly larger than the size of the outer surface of the steel stud 200 so that the steel stud 200 can be easily inserted into the hollow portion of the steel node 500. As described above, the gap between the two is filled with a high strength caulking material.

FIG. 5A shows a top view of a steel node 1500 according to another embodiment; fig. 5B shows a side view of the steel node 1500 in fig. 5A. In the embodiment shown in fig. 5A-5B, steel node 1500 includes a rectangular hollow steel tube 1501 and standoffs 1502, 1503 extending from steel tube 1501. The structure of the steel duct 1501 is similar to the rectangular steel duct of the steel node 500 shown in fig. 4, and the hollow portions thereof are adapted to receive corresponding steel column heads of the rectangular columns 100A, 100B. The mounts 1502, 1503 are preferably made of steel material.

standoffs 1502, 1503 extend from the mutually perpendicular surfaces of steel pipe 1501, respectively in mutually perpendicular directions, and are preferably connected to the outer surface of steel pipe 1501 by welding. The brackets 1502, 1503 are used to connect lateral horizontal structures, such as beam structures, and are particularly adapted to receive steel column heads of beam structures having a steel-to-concrete structure. The mounts 1502, 1503 have similar structures and, thus, the features described for one mount 1502/1503 may be similarly applicable to the mount 1503/1502. In the embodiment shown in fig. 5A-5B, the brackets 1502, 1503 are formed as male brackets to which the steel column heads of the mating beam structure are sleeved (from above) and preferably connected by high-strength bolts, e.g. via holes 1504 shown in fig. 5B. In the illustrated embodiment, the base plate of the holder 1502 has a width greater than the maximum width between the sidewalls, and the base plate extends outwardly from the outer surface of both sidewalls to form two sided bosses 1505A, 1505B; similarly, the support 1503 also has two-sided bosses 1506A, 1506B. The bosses of the mounts 1502, 1503 are used to support corresponding structures (e.g., the bottom of the side walls) of the female end when the female end of the mating beam structure is capped over the mounts 1502, 1503.

In a preferred embodiment, the gap between the male abutment and the steel column head of the beam structure is filled with a high strength caulking material. The high-strength caulking material preferably uses epoxy resin, and more particularly uses a material suitable for connecting steel materials. The high-strength gap filling material can effectively ensure the fixed connection between the supports 1502 and 1503 and the steel column head of the matched beam structure, and simultaneously fill the gap between the supports and the steel column head, thereby compensating the machining error possibly generated in the machining process, reducing the requirement on manufacturing precision and being convenient for installation. In a more preferred embodiment, after the steel column head of the beam structure is fitted to the seat, the top of the steel column head is further fixedly connected to the surface of the steel tube 1501 by a welded connection. It should be understood by those skilled in the art that while the embodiment of fig. 5A-5B shows the standoffs extending from two mutually perpendicular outer surfaces of the steel tube 1501, a different number of standoffs, and/or different positions of extension, may be used depending on the application.

FIG. 6A shows a top view of a steel node 2500 according to yet another embodiment; fig. 6B shows a side view of steel node 2500 in fig. 6A. In the embodiment shown in fig. 6A-6B, steel node 2500 includes a rectangular hollow steel tube 2501 and supports 2502, 2503 extending from steel tube 2501. The structure of steel tube 2501 is similar to the structure of the rectangular steel tube of steel node 500 shown in fig. 4, and its hollow portion is adapted to receive the corresponding steel column heads of rectangular columns 100A, 100B. The supports 2502, 2503 are preferably made of steel.

The structure of steel node 2500 is substantially similar to that of steel node 1500 shown in fig. 5A-5B, except that supports 2502, 2503 are formed in the form of female supports into which the steel column heads of the mating beam structure are inserted (from above) and are preferably connected with the female supports by high-strength bolts, for example via holes 2504 shown in fig. 6B. Similarly, in the preferred embodiment, the gap between the female brace and the steel column head of the beam structure is filled with a high strength caulking material. In a more preferred embodiment, after the steel column head of the beam structure is fitted to the seat, the top of the steel column head is further fixedly connected to the surface of the steel tube 2501 by a welded connection. It should be understood by those skilled in the art that although the embodiment of fig. 6A-6B shows the abutments extending from two mutually perpendicular outer surfaces of steel tube 2501, a different number and/or different positions of the abutments could be used depending on the application.
