[0070] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0071] The present invention will be further explained below with reference to specific embodiments.

[0072] Example 1

[0073] like Figures 1 to 14 As shown, the reinforced steel-concrete composite column provided in this embodiment includes a steel pipe 3 and concrete 1 poured inside the steel pipe 3; a reinforcing rod is provided on the steel pipe 3; the reinforcing rod is used to enhance the connection strength between the steel pipe 3 and the concrete 1. Since the reinforcing rod enhances the connection strength between the steel pipe 3 and the concrete 1, it enhances the integrity of the steel pipe 3 and the concrete 1, and avoids the phenomenon of the concrete 1 separating from the wall of the steel pipe 3.

[0074] Preferably, the reinforcing rod is a bolt 2; the side wall of the steel pipe 3 is provided with bolt holes 4. The bolt 2 passes through the bolt holes 4 on the side wall of the steel pipe 3, which not only achieves a reinforced connection but also facilitates installation and use. Preferably, the bolt 2 is an extended ribbed bolt.

[0075] The two ends of the reinforcing rod are respectively connected to the opposite side walls of the steel pipe 3, so that the reinforcing rod tightly connects the two side walls to the concrete 1 between the side walls. This arrangement allows the reinforcing rod to act on the opposite side walls of the steel pipe 3, thereby improving the reinforcing effect of the reinforcing rod.

[0076] The reinforcing rod is perpendicular to the side wall of the steel pipe 3, which facilitates the installation of the reinforcing rod. At the same time, the perpendicular installation further enhances the force exerted by the reinforcing rod on the steel pipe 3.

[0077] like Figures 5 to 7 As shown, multiple reinforcing rods are arranged at intervals along the length of the steel pipe 3. That is, the intervals between the steel pipe 3 and the concrete 1 are strengthened by the multiple reinforcing rods arranged at intervals along the length, which greatly improves the integrity of the steel pipe 3 and the concrete 1.

[0078] After the reinforcing rod is connected to the steel pipe 3, concrete 1 is poured to form a steel pipe 3 concrete 1 column. This allows the reinforcing rod to be poured onto the steel pipe 3 along with the concrete 1, which enhances the integrity of the reinforcing rod, the steel pipe 3 and the concrete 1, and improves the reinforcement effect.

[0079] Wherein, the steel pipe 3 concrete 1 column of the application can be in various structural forms, for example: as shown in Figure 1 , which is a middle column structure, that is, the steel pipe 3 is in a cross shape, and the four edges of the cross shape are provided with reinforcing rods; or as shown in Figure 2 and Figure 3 , which is an edge column structure, the steel pipe 3 is in a T shape, and the three edges of the T shape are provided with reinforcing rods; or as shown in Figure 4 , which is a corner column structure, the steel pipe 3 is in an L shape, and the two edges of the L shape are provided with reinforcing rods.

[0080] For example: the steel pipe 3 is a square steel pipe, and a T-shaped steel column 5 is connected outside the square steel pipe; a plurality of reinforcing rods are provided on the square steel pipe in the thickness direction of the square steel pipe, that is, a plurality of reinforcing rods are provided on the square steel pipe from the perspective of the cross section.

[0081] As shown in Figure 8 , the T-shaped steel column 5 includes a column flange 51 and a column web 52 connected perpendicularly, and the column web 52 is connected with the outer wall of the square steel pipe.

[0082] As shown in Figure 8 , it can be a middle column structure, that is, the T-shaped steel column 5 is four, and the four T-shaped steel columns 5 are arranged around the four edges of the square steel pipe to form a cross shape.

[0083] As shown in Figure 9 and Figure 10 , or it is an edge column structure, that is, the T-shaped steel column 5 is three, and the three T-shaped steel columns 5 are arranged around the three edges of the square steel pipe to form a T shape.

[0084] As shown in Figure 11 and Figure 12 , or it is a middle column structure, that is, the T-shaped steel column 5 is two, and the two T-shaped steel columns 5 are arranged around the opposite two edges of the square steel pipe to form a straight line shape.

[0085] As shown in Figure 13 , or it is a corner column structure, that is, the T-shaped steel column 5 is two, and the two T-shaped steel columns 5 are arranged around the adjacent two edges of the square steel pipe to form an L shape.

[0086] The shape of the steel pipe 3 is not limited in the application, and different shapes of the steel pipe 3 can be selected according to the application.

[0087] Example 2

[0088] The embodiment discloses a fabricated building using the above-mentioned steel pipe concrete column.

[0089] As shown in Figure 15As shown, the king-shaped steel beam support prefabricated slab assembly type composite floor provided by the embodiment comprises a king-shaped steel beam 12 and a prefabricated floor slab 11. The king-shaped steel beam 12 is lapped on the top of a steel pipe concrete column steel pipe 3, and the end plate 3a on the top of the steel pipe 3 is fixedly connected to the lower flange of the king-shaped steel beam 12 by bolts.

[0090] As shown, Figures 16-17 The king-shaped steel beam 12 comprises an upper flange 12-1, a middle flange 12-3, a lower flange 12-3 and a web 12-4; the middle flange 12-3 is wider than the upper flange 12-1; the end of the prefabricated floor slab 11 is lapped on the middle flange 12-3; and the top surface of the upper flange 12-1 is flush with the upper surface of the prefabricated floor slab 11. The width difference of the middle flange 12-3 relative to the upper flange 12-1 is set according to the strength requirement of the prefabricated floor slab 11 at the lapped part. Generally, the middle flange 12-3 is 40-120 mm wider than the upper flange 12-1. The width of the middle flange 12-3 is set according to the support strength or the requirement of the adapted connecting structure. Preferably, the lower flange 12-3 and the upper flange 12-1 are of equal width, so as to improve the generalization and replaceability of the components, thereby improving the production efficiency.

[0091] In a specific application scenario, the widths of the upper flange 12-1, the middle flange 12-3 and the lower flange 12-3 increase in turn. That is, the three flanges of the king-shaped steel beam 12 are of a stepped shape and increase in width from top to bottom. For example, the widths of the upper flange 12-1, the middle flange 12-3 and the lower flange 12-3 increase in an arithmetic sequence. The difference of the arithmetic sequence is 60-100 mm. The king-shaped steel beam 12 of the stepped shape and increasing in width in turn is more convenient for lapping of the multi-layer prefabricated floor. During construction, different prefabricated floor slabs 11 or prefabricated slab structures can be lapped on the lower flange 12-3 and the middle flange 12-3 in turn, and the two layers of structures are filled with concrete or pipelines, or form a sandwich structure to improve the heat insulation performance. The prefabricated floor slab 11 is prefabricated in a factory and is composed of concrete, double-layer steel bars and stirrups.

[0092] As shown, Figure 15 The end of the prefabricated floor slab 11 for lapping with the middle flange 12-3 comprises a step part 11-1, the step part 11-1 is inserted into the U-shaped groove between the middle flange 12-3 and the upper flange 12-1, and a sink 11-3 for receiving the upper flange 12-1 is arranged above the step part 11-1.

[0093] The embodiment further comprises shear reinforcement 16; the step part 11-1 is provided with a clamping groove 11-2 on the outer side end surface of one side of the web 12-4; and the two ends of the shear reinforcement 16 respectively extend into the clamping grooves 11-2 of the adjacent two prefabricated floor slabs 11. A plurality of shear reinforcements 16 are uniformly arranged in the clamping grooves 11-2 at equal intervals. Figure 16 and Figure 18As shown, the web plate 12-4 is provided with a through hole 12-5 for the anti-shear steel bar 16 to pass through. In this embodiment, the cross section of the clamping groove 11-2 is V-shaped, and the notch width of the V-shaped clamping groove is equal to the height of the step part 11-1, wherein the height of the step part 11-1 is 40-100 mm.

[0094] The sink 11-3 is provided with a steel bar connecting part 18 extending from the inside of the prefabricated floor slab 11; the steel bar connecting parts 18 of two adjacent prefabricated floor slabs 11 are connected by the lap steel bar 17 at the butt joint. The web plate 12-4 is provided with a through hole 12-6 for the lap steel bar 17 to pass through. The middle flange 12-3 is provided with a plurality of studs 15.

[0095] In addition, the gap between the king-shaped steel beam 12 and the prefabricated floor slab 11 is filled with joint concrete 13, which can be UHPC or ECC concrete.

[0096] The prefabricated floor slab 11 is arranged on the upper surface of the middle flange 12-3 on both sides of the king-shaped steel beam 12, and the upper flange 12-1 of the steel beam is flush with the upper surface of the prefabricated floor slab 11, thereby reducing the overall height of the floor system and thus reducing the building floor height. On the other hand, the use of prefabricated floor slabs 11 avoids a large amount of work such as formwork, steel bar binding and concrete pouring on site, and has the advantages of fast construction speed, high industrialization degree and energy saving and environmental protection.

[0100] The application sets the rotatable reinforcing rib assembly 120 in the steel pipe pile 100, after the steel pipe pile 100 is inserted into the set bore, the rotatable reinforcing rib assembly 120 is forced to swing by the gravity of the rod or the added cement, the rib plate 121 is extended from the hollow steel pipe 110 through the pre-opening 111, a reinforcing rib plate 121 is formed, thereby increasing the supporting capacity of the steel pipe pile 100. It has the characteristics of convenient construction, small damage and the like.

[0101] A plurality of pre-openings 111 are arranged on the pipe wall of the hollow steel pipe 110 and spaced along the axial direction of the hollow steel pipe 110.
