[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] This utility model provides a technical solution: such as Figures 1 to 5 , Figure 7 As shown in this embodiment, a convenient assembly-type steel-concrete composite column joint connection device includes a steel-concrete composite body 1, a steel plate 2, and an assembly connection component 3. The assembly connection component 3 includes a column end connecting sleeve 30, with a groove 31 inside the column end connecting sleeve 30 and second insertion holes 32 on both sides of the groove 31. Second fixing blocks 11 are fixedly connected to both ends of the column end connecting sleeve 30. The second fixing blocks 11 are connected to a first fixing block 10 by screws. One end of the first fixing block 10 is fixedly connected to the outside of the steel-concrete composite body 1. A connecting plate 22 is inserted into the groove 31 of the column end connecting sleeve 30. A first insertion hole 23 is opened inside the connecting plate 22. A pin rod 38 is inserted and connected to the column end connecting sleeve 30 and the connecting plate 22. The pin rod 38 passes through and connects the first insertion hole 23 and the second insertion hole 32. A first fixing rod 33 is fixedly connected to one end of the pin rod 38, and a second fixing rod 34 is fixedly connected to one end of the first fixing rod 33. A lead screw 35 is fixedly connected to one end of the lead screw 35. A second nut 392 is rotatably connected to the outside of the lead screw 35.
[0023] Furthermore, such as Figures 5 to 7 As shown, a first nut 37 is fixedly connected to one end of a second nut 392. The first nut 37 has an internal thread 393. The first nut 37 is rotatably connected to the outside of a sleeve 36. An external thread 391 is provided at one end of a sleeve 36. A lead screw 35 is inserted inside the sleeve 36. A through hole 39 is provided inside the sleeve 36. A fixing plate 21 is fixedly connected to one end of a connecting plate 22. The fixing plate 21 is connected to one end of a steel plate 2 by bolts.
[0024] In this scheme, the operator first places the column end connecting sleeve 30 at the end of the steel pipe concrete body 1, aligning the second fixing blocks 11 at both ends of the column end connecting sleeve 30 with the first fixing blocks 10 on the outside of the steel pipe concrete body 1, and then fixes the two together with screws, thereby realizing the connection between the column end connecting sleeve 30 and the steel pipe concrete body 1. Next, the connecting plate 22 is inserted into the groove 31 of the column end connecting sleeve 30, ensuring that the first insertion hole 23 on the connecting plate 22 is aligned with the second insertion holes 32 on both sides of the groove 31 of the column end connecting sleeve 30. When the first fixing rod 33 and the second fixing rod 34 move relative to each other, the pin 38 moves accordingly within the first insertion hole 23 and the second insertion hole 32, inserting the pin 38 into the first insertion hole 23 and the second insertion hole 32, thus initially connecting the column end connecting sleeve 30 and the connecting plate 22. Then, the lead screw 35 moves within the sleeve 36, and the operator rotates the first nut 37 and the second nut 392. The first nut 37 rotates and moves outside the lead screw 35, while the second nut 392 rotates and fixes outside one end of the sleeve 36. As the first nut 37 and the second nut 392 rotate, the lead screw 35 is tightened, making the pin 38 more secure and enhancing the connection stability between the column end connecting sleeve 30 and the connecting plate 22. Finally, the fixing plate 21 at one end of the connecting plate 22 is aligned with the steel plate 2, and the fixing plate 21 and the steel plate 2 are fixedly connected with bolts. At this point, the entire node connection device is assembled.
[0025] In this implementation, the column end connecting sleeve 30 is connected to the steel pipe concrete body 1 by screws through the first fixing block 10 and the second fixing block 11. The column end connecting sleeve 30 and the connecting plate 22 are initially connected by inserting the pin rod 38 into the first insertion hole 23 and the second insertion hole 32. The screw rod 35, the first nut 37 and the second nut 392 are used to tighten the screw rod 35 to further fix the pin rod 38, which enhances the connection stability between the column end connecting sleeve 30 and the connecting plate 22. Finally, the fixing plate 21 of the connecting plate 22 is connected to the steel plate 2 by bolts. Compared with traditional welding and other connection methods, the connection method between the various components shortens the construction time and improves the construction efficiency. The operator only needs to follow the clear steps to complete the connection of the column end connecting sleeve 30 to the steel pipe concrete body 1, the connection plate 22 to the column end connecting sleeve 30, and the connection plate 22 to the steel plate 2 in sequence, which reduces the construction difficulty and the technical requirements of the operator.
[0026] This utility model provides a convenient assembled steel pipe concrete column joint connection device. The specific working principle is as follows: The operator first places the column end connecting sleeve 30 at the end of the steel pipe concrete body 1, so that the second fixing blocks 11 at both ends of the column end connecting sleeve 30 are aligned with the first fixing blocks 10 on the outside of the steel pipe concrete body 1. Then, the two are fixed together with screws, thereby realizing the connection between the column end connecting sleeve 30 and the steel pipe concrete body 1. Next, the connecting plate 22 is inserted into the groove 31 of the column end connecting sleeve 30, ensuring that the first insertion hole 23 on the connecting plate 22 is aligned with the second insertion holes 32 on both sides of the groove 31 of the column end connecting sleeve 30. When the first fixing rod 33 and the second fixing rod 34 move relative to each other, the pin 38 moves accordingly within the first insertion hole 23 and the second insertion hole 32, inserting the pin 38 into the first insertion hole 23 and the second insertion hole 32, thus initially connecting the column end connecting sleeve 30 and the connecting plate 22. Then, the lead screw 35 moves within the sleeve 36, and the operator rotates the first nut 37 and the second nut 392. The first nut 37 rotates and moves outside the lead screw 35, while the second nut 392 rotates and fixes outside one end of the sleeve 36. As the first nut 37 and the second nut 392 rotate, the lead screw 35 is tightened, making the pin 38 more secure and enhancing the connection stability between the column end connecting sleeve 30 and the connecting plate 22. Finally, the fixing plate 21 at one end of the connecting plate 22 is aligned with the steel plate 2, and the fixing plate 21 and the steel plate 2 are fixedly connected with bolts. At this point, the entire node connection device is assembled.
