[0051] See also Figures 1-8 As shown, the embodiment of the present application provides a beam-column positioning structure of an assembled concrete structure, which includes a lower precast column 10, an upper precast column 20, a left precast beam 30, a right precast beam 40 and a positioning square tube 50, wherein:

[0052] The lower precast column 10 is pre-embedded with a lower tube 11 and a lower connecting plate 12. Both extend vertically upward from the top of the lower precast column 10. The lower tube 11 is pre-filled with concrete to a level with the top of the lower precast column 10. Two lower connecting plates 12 are symmetrically located on the left and right sides of the lower tube 11.

[0053] An upper tube 21 and an upper connecting plate 22 are pre-buried within the upper precast column 20. Both the upper tube 21 and the upper connecting plate 22 extend vertically downward from the bottom surface of the upper precast column 20. The upper tube 21 is pre-filled with concrete to a level with the bottom surface of the upper precast column 20. Two upper connecting plates 22 are symmetrically located on the left and right sides of the upper tube 21.

[0054] Two left connecting plates 31 are pre-buried in the left precast beam 30 . Both left connecting plates 31 extend horizontally to the right from the right side of the left precast beam 30 . The two left connecting plates 31 are spaced apart in the vertical direction.

[0055] Two right connecting plates 41 are pre-buried in the right precast beam 40 . Both right connecting plates 41 extend horizontally to the left from the left side of the right precast beam 40 . The two right connecting plates 41 are spaced apart in the vertical direction.

[0056] The upper connecting plate 22, lower connecting plate 12, left connecting plate 31, and right connecting plate 41 are all provided with long waist holes. The bottom ends of the left and right precast beams 30 and 40 rest on the left and right sides of the top surface of the lower precast column 10, respectively. The left connecting plate 31 and right connecting plate 41 on the lower side are connected to the lower connecting plate 12 on the left and right sides, respectively, by bolts 60 inserted through the long waist holes of the two. The bottom end of the positioning square tube 50 is inserted into the lower tube 11, and the top end of the positioning square tube 50 is inserted into the upper tube 21. The upper connecting plate 22 on the left is connected to the left connecting plate 31 on the upper side by bolts 60 inserted through the long waist holes of the two. The upper connecting plate 22 on the right is connected to the right connecting plate 41 on the upper side by bolts 60 inserted through the long waist holes of the two.

[0057] When assembling each prefabricated component, first place the left prefabricated beam 30 and the right prefabricated beam 40 on the left and right sides of the top surface of the lower prefabricated column 10, so that the long waist holes on the left connecting plate 31 on the lower side of the left prefabricated beam 30 and the right connecting plate 41 on the lower side of the right prefabricated beam 40 respectively coincide with the long waist holes on the lower connecting plate 12 on the left side and the lower connecting plate 12 on the right side of the lower prefabricated column 10, insert the bolts 60 into the long waist holes of the two and tighten them with the nuts 70, thereby completing the accurate positioning between the left prefabricated beam 30, the right prefabricated beam 40 and the lower prefabricated column 10.

[0058] Then, the positioning square tube 50 is inserted into the lower tube 11 of the lower prefabricated column 10 , and the bottom end of the positioning square tube 50 is placed on the concrete surface in the lower tube 11 . Then, the upper tube 21 of the upper precast column 20 is aligned with the positioning square tube 50 and the upper precast column 20 is lowered. The upper tube 21 is sleeved on the positioning square tube 50 and moved downward until the top of the positioning square tube 50 is against the concrete surface in the upper tube 21. The upper precast column 20 is supported by the positioning square tube 50. In this way, the preliminary positioning of the upper precast column 20 is achieved. Then, through fine-tuning, the long waist holes on the upper left connecting plate 31 of the left precast beam 30 and the upper right connecting plate 41 of the right precast beam 40 are made to coincide with the long waist holes on the upper connecting plate 22 on the left and the upper connecting plate 22 on the right of the upper precast column 20 respectively. The bolts 60 are inserted into the long waist holes of the two and tightened with the nuts 70, thereby completing the accurate positioning between the left precast beam 30, the right precast beam 40 and the upper precast column 20.

[0059] The beam-column positioning structure of the prefabricated concrete structure provided in the embodiment of the present application can quickly and easily realize the positioning between the upper prefabricated column 20 and the lower prefabricated column 10 through the upper tube 21, the lower tube 11 and the positioning square tube 50. The bolts 60 between the connecting plates can realize accurate positioning between the left prefabricated beam 30, the right prefabricated beam 40 and the upper prefabricated column 20 and the lower prefabricated column 10, and can strengthen the connection between the prefabricated components to avoid movement after positioning.

[0060] See also Figure 8 As shown, in order to facilitate the lifting of the lower prefabricated column 10, a lifting hole 111 is provided on the lower tube 11. The lifting hole 111 is located on the tube body of the lower tube 11 that extends out from the top surface of the lower prefabricated column 10. In this way, when lifting the lower prefabricated component, a lifting tool such as a lifting rope can be inserted into the lifting hole 111, making it easier to lift the lower prefabricated component and also preventing the lower prefabricated column 10 from slipping, ensuring that the lower prefabricated column 10 will not fall during lifting.

[0061] In order to prevent the lower tube 11 from separating from the lower prefabricated column 10 when the lower prefabricated column 10 is hoisted, a reinforcement hole is provided on the lower tube 11. The reinforcement hole is located on the tube body of the lower tube 11 buried in the lower prefabricated column 10. A reinforcement rib 112 is passed through the reinforcement hole. The reinforcement rib 112 is buried in the lower prefabricated column 10, thereby strengthening the connection strength between the lower tube 11 and the lower prefabricated column 10.

[0062] See also Figure 1-Figure 5 As shown, in the embodiment of the present application, a plurality of vertical ribs 13 are embedded in the lower precast column 10, and the vertical ribs 13 extend vertically upward from the top surface of the lower precast column 10. The bottom surface of the upper precast column 20 is provided with a plurality of sockets, and the plurality of vertical ribs 13 are inserted into the sockets. When the upper precast column 20 is hoisted, the vertical ribs 13 on the lower precast column 10 are inserted into the sockets of the upper precast column 20, which further ensures the accurate positioning of the upper precast column 20, and the vertical ribs 13 can also enhance the structural strength. A left curved rib 32 is embedded in the left precast beam 30, and the left curved rib 32 extends from the right side of the left precast beam 30 and bends upward. A right curved rib 42 is embedded in the right precast beam 40, and the right curved rib 42 extends from the left side of the right precast beam 40 and bends upward. The left curved rib 32 and the right curved rib 42 can be welded together with adjacent vertical ribs 13. A left stirrup 33 is embedded in the left precast beam 30 and extends from the top surface of the left precast beam 30 ; a right stirrup 43 is embedded in the right precast beam 40 and extends from the top surface of the right precast beam 40 .
