Exemplary embodiments of the present invention are described below with reference to the accompanying drawings. It is to be understood that the drawings and the following description of the drawings are merely exemplary and are not restrictive in any way, and that the scope of the present invention is defined by the appended claims.

fig. 1A shows a side view of a foundation top layer steel-reinforced concrete structural L-shaped column 100 (hereinafter referred to simply as L-shaped 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 foundation 3 top 3 layer 3 steel 3- 3 reinforced 3 concrete 3 structural 3 L 3- 3 shaped 3 column 3 100 3 of 3 FIG. 3 1 3A 3. 3

referring to fig. 1A, the L-shaped column 100 includes a reinforced concrete column 300, a steel column head 200 located at an upper end of the reinforced concrete column 300, and a basal-top steel column head 400 located at a lower end of the reinforced concrete column 300. The reinforced concrete column 300, the steel column head 200, and the steel column head 400 of the L-shaped column 100 are all L-shaped 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 steel 301 at a plurality of corners (6 corners) of the column 300, a plurality of longitudinally stressed rebars 302 arranged along the circumference of the column 300, and concrete 303 filling most of the structure of the column. The angle steel 301 disposed at the corners of the column 300 is connected (e.g., bolted, or welded) to the steel column head 200 and the steel column head 400 of the foundation layer, facilitating the pouring of concrete, and is particularly advantageous in maintaining the dimensional accuracy of the column 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 a single longitudinal force-receiving rebar 302 is labeled in fig. 2, but it should be understood that in the embodiment shown in fig. 2, 12 longitudinal force-receiving rebars are disposed along the entire circumference of the column 300, particularly circumferentially around the overlapping portions of two mutually perpendicular elongated structures of the L-shaped column 100 (labeled longitudinal force-receiving rebars 302') for reinforcing the overall 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 steel-reinforced concrete structural L-shaped column 100 is prefabricated in a factory. Specifically, the upper steel stud 200, the top-base steel stud 400, the steel diaphragms (not shown), the angle steel 301, the longitudinal load-bearing steel bars 302, and the stirrups are first connected (e.g., by bolting) at the factory into a structurally stable L-shaped stud skeleton 100' (excluding concrete). Fig. 2 shows a side view of the L-shaped column steel skeleton 100' (i.e., the steel-concrete structure L-shaped column 100 in a state where no concrete is poured). As can be seen more particularly in fig. 2, the longitudinal load-bearing rebars 302 extend along the longitudinal direction, along the entire length of the L-shape 100 of the reinforced concrete structure. Subsequently, on the work bench, the L-shaped column steel skeleton 100' is supported by using a standard steel formwork, and concrete is poured to form a steel-reinforced concrete structure L-shaped column 100 as shown in fig. 1A.

fig. 3A shows a side view of a rectangular steel pipe a201 (in a state where concrete is not poured) of the steel stud 200. Fig. 3B shows a top view of the rectangular steel pipe a201 in fig. 3A, showing a view of the upper surface of the upper plate a 202. Fig. 3C shows a view from above looking down, taken along section line B-B, showing a view of the upper surface of lower plate a 204. In the L-shaped column skeleton 100' shown in fig. 2, a longitudinal force-receiving rebar 302 is connected (e.g., bolted) to an upper plate a202 of a rectangular steel pipe a201 through a hole B205 in a lower plate a204 of the rectangular steel pipe a201, through a hole a203 in the upper plate a 202. The upper plate a202 and the lower plate a204 and the holes thereon can effectively fix the position of the longitudinal force-bearing rebar 302. The structure of the upper plate a202 and the lower plate a204 of the rectangular steel tube a201 can realize better fixation of the position of the longitudinal stressed steel bar 302, and particularly avoid deformation at the steel column head, so as to facilitate connection with a matched steel node. In a preferred embodiment, the lower plate a204 is provided to have a hollow portion. The rectangular steel pipe a201 is fixed (e.g., bolted) to the angle iron 301 through a hole provided in the side wall, and is thus connected to a portion of the L-shaped column skeleton 100' corresponding to the column body 300 (fig. 1A).

fig. 4A shows a side view of a rectangular steel tube B401 (in a state where concrete is not poured) of the steel stud 400 of the base-top layer. Fig. 4B shows a view from below looking upwards, taken along section line C-C, showing a view of the lower surface of its upper plate B404. Fig. 4C shows a view from below looking up, taken along section line D-D, showing a view of its lower plate B402. In the L-shaped column skeleton 100' shown in fig. 2, the longitudinal force-receiving rebar 302 is connected (e.g., bolted) to the lower plate B402 of the rectangular steel tube B401 through a hole D405 in the upper plate B404 of the rectangular steel tube B401, through a hole C403 in the lower plate B402. The lower plate B402 and the upper plate B404 and the holes thereon can effectively fix the position of the longitudinal force-bearing steel bars 302. The lower plate B402 and the upper plate B404 of the rectangular steel tube B401 and the holes thereon can achieve better fixation of the position of the longitudinal force-bearing steel bars 302, and particularly avoid deformation at the steel column head of the foundation top layer, so as to facilitate connection with the matched steel node, and particularly facilitate maintaining strength and avoiding deformation during pouring concrete on the steel column head of the foundation top layer and the node of the foundation top layer to be embedded into the foundation cap. In a preferred embodiment, the upper plate B404 is provided to have a hollow portion. The rectangular steel tube B401 is fixed (e.g., bolted) to the angle iron 301 through a hole provided on the side wall, and is thus connected to a portion of the L-shaped column skeleton 100' corresponding to the column body 300 (fig. 1A).

The steel capital-top column head 400 (or rectangular steel tube B401) has substantially the same structure as the steel column head 200 (or rectangular steel tube a201), except that since the steel capital-top column head 400 corresponds to the capital layer and is used to connect to foundation beams through the steel capital-top nodes and cast concrete to embed foundation cap and foundation slab, which are at the bottommost layer of the building, and its own accuracy and installation accuracy directly determine the positioning accuracy of the various elements of the entire building structure, the force at the steel capital-top column head 400 is greater, the strength requirement at the steel capital-top column head 400 is higher, and the accuracy requirement for it is higher, so that the longitudinal length of the steel capital-top column head 400 is chosen to be greater than the longitudinal length of the steel column head 200, as shown in the figures.

Fig. 5A shows an assembled structure of the foundation top layer steel node 500 and the foundation top layer steel-node-concrete structure L-shaped column 100 connected together, in which the outer surface of the rectangular steel tube B401 of the foundation top layer steel stud 400 is shown by a dotted line. Fig. 5B shows the skeletal structure of the assembled structure of fig. 5A to more clearly show the mating relationship of the base top layer steel node 500 and the base top layer steel-node concrete structural L-shaped column 100.

Referring specifically to fig. 5A, the capital-level steel stud 400 of the L-shaped stud 100 is inserted into a capital-level steel node 500. The size of the outer surface of the basic top layer steel node 500 is substantially the same as that of the outer surface of the reinforced concrete column 300, so that a substantially flat outer surface is formed after the basic top layer steel node 500 is assembled with the L-shaped column 100, reducing subsequent adjustment operations. The gap between the outer surface of the capital-level steel stud 400 and the inner surface of the capital-level steel stud 500 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 rectangular steel pipe B401 of the steel column head 400 on the top base layer and the steel node 500 on the top base layer, and simultaneously fills the gap between the outer surface of the steel column head on the top base layer and the inner surface of the steel node 500 on the top base layer, 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. 6A shows a front view of the base-top layer steel node 500 of fig. 5A, and fig. 6B shows a top view of the base-top layer steel node 500. Fig. 6A-6B more clearly illustrate the structure of the base-top layer steel node 500. Specifically, the base-top layer steel node 500 includes a hollow L-shaped frame 501, and a bottom plate 502. When the L-shaped column 100 is mounted to the foundation top level steel node 500, the foundation top level steel stud 400 is received in the hollow of the L-shaped frame 501 and is fixedly connected thereto by a high strength caulking material, as described above. A plurality of fastening holes 503 are provided in the bottom plate 502 for attaching the foundation top layer steel node 500 to a foundation cap or foundation bottom plate, e.g. via bolting and/or spot welding, etc. In the illustrated embodiment, a plurality of fixing holes 503 are arranged on the bottom plate 502 at positions corresponding to the outer periphery of the frame 501 in the circumferential direction. In an alternative embodiment, a plurality of fixing holes may be disposed at positions of the bottom plate 502 corresponding to the inside of the frame 501, so that when the foundation top layer steel node 500 is fixed to the foundation cap or the foundation bottom plate, the entire bottom plate is uniformly stressed and can endure a large external force. In other embodiments, the fixing holes 503 are not limited to the arrangement described above, but may be arranged in any pattern as long as it can satisfy the national standards and strength requirements.

In the embodiment shown in fig. 6A-6B, the foundation top layer steel nodes 500 are used only to connect the foundation top layer steel-node concrete structural L-columns 100 to the foundation cap or foundation bedplate, and not to connect the transverse beam structures, such as foundation beams. In an alternative embodiment, the foundation top layer steel node further comprises a brace for connecting the transverse beam structure, such as shown in the embodiment of fig. 7A-7B.

Fig. 7A shows a front view of a base top layer steel node 1500 according to another embodiment, and fig. 7B shows a top view of the base top layer steel node 1500 in fig. 7A. Specifically, the base top layer steel node 1500 includes a hollow L-shaped frame 1501, a bottom plate 1502, and standoffs 1510, 1520 extending from the L-shaped frame 1502. The structure of the L-shaped frame 1501 and the base plate 1502 is similar to the structure of the L-shaped frame 501 and the base plate 502 of the base-top layer steel node 500 shown in fig. 7A-7B. The brackets 1510, 1520 are preferably made of steel material and are used to connect a transverse beam structure, such as a foundation beam.
