[0004] With respect to the above-mentioned related technologies, embedded parts are usually first installed on the floor formwork and the column formwork, and the embedded parts are fixed when the floor and the column are cast and formed by pouring concrete. However, the column formwork is prone to horizontal displacement due to the vibration of concrete during pouring, which makes the distance between the two adjacent columns deviate from the predetermined distance. The embedded parts on the column formwork deviate from the predetermined position, resulting in a deviation in the distance between the two connecting plates in the node unit, thereby affecting the installation of the constraint support body. Summary of the invention

[0044] Taking one floor of a building as an example, a plurality of columns 2 are arranged in an array between upper and lower adjacent floor plates 1 , and columns 2 in the same column extend along the same straight line direction, and a node unit 7 is formed between two adjacent columns 2 in each column.

[0045] Reference Figure 1 and Figure 2 The floor 1 is cast by setting up the formwork. When the formwork of the floor 1 is set up, the first embedded part 3 and the steel bars passing through the first embedded part 3 are placed in the floor formwork, and then concrete is cast in the floor formwork. After the floor 1 is formed, the side of the first embedded part 3 facing the column 2 is flush with the side of the floor 1 facing the column 2.

[0046] Reference Figure 2 and Figure 3After the upper and lower floor slabs 1 are cast, a column formwork 24 is set up between the upper and lower floor slabs 1 to cast and form a column 2. A column reinforcement frame 8 is provided in the column 2 to form the shape of the column 2, and both the column 2 and the column reinforcement frame 8 are square structures. The column reinforcement frame 8 includes a plurality of vertical steel bars 81 extending in the vertical direction, and a plurality of stirrups 82 enclosed outside the vertical steel bars 81 in the vertical direction.

[0047] Reference Figure 1 and Figure 2 The number of the second embedded parts 4 on each column 2 is two, the two second embedded parts 4 on the column 2 are simultaneously located at the top or bottom of the column 2, the two second embedded parts 4 on the column 2 are respectively located in two adjacent node units 7, and the positions of the second embedded parts 4 on the two adjacent columns 2 are staggered up and down, so that the number of the second embedded parts 4 in the node unit 7 is two, and the two second embedded parts 4 in the node unit 7 are respectively located at two opposite diagonals of the node unit 7.

[0048] Reference Figure 2 and Figure 3 , the position and quantity of the first embedded parts 3 correspond to the second embedded parts 4 one by one. In the node unit 7, the top surface of the second embedded parts 4 located above abuts against the lower surface of the first embedded parts 3 on the top floor 1, and the bottom surface of the second embedded parts 4 located below abuts against the upper surface of the first embedded parts 3 on the bottom floor 1. The first embedded parts 3 and the second embedded parts 4 relative to each other jointly form an angle for the connecting plate 5 to abut, and the angle is a right angle. There are two connecting plates 5 in each node unit 7, and the two connecting plates 5 are respectively located at the two opposite diagonals of the node unit 7, and the connecting plates 5 are welded to the angle formed by the first embedded parts 3 and the second embedded parts 4.

[0049] Reference Figure 1 Each node unit 7 has a constraint support body 6, and the two ends of the core material of the constraint support body 6 that are far away from each other are respectively welded to the two connecting plates 5 of the node unit 7, so that the constraint support body 6 is installed obliquely in the node unit 7, and the constraint support bodies 6 of two adjacent node units 7 are inclined in opposite directions.

[0050] Reference Figure 3 and Figure 4 , wherein each second embedded part 4 includes a mounting frame 41, an extension seat 42, an adjustment plate 43, an adjustment sleeve 44, a guide seat 45 and a guide sleeve 46. The mounting frame 41 abuts against the outer side of the column reinforcement frame 8, and the mounting frames 41 in the two second embedded parts 4 on the same column 2 abut against the opposite sides of the column reinforcement frame 8 respectively. The mounting frame 41 has a mounting cavity 9 with an opening facing away from the column reinforcement frame 8, and the mounting cavity 9 passes through the mounting frame 41 toward one end of the first embedded part 3, and the mounting frame 41 abuts against the surface of the first embedded part 3 at one end of the first embedded part 3.

[0051] The adjustment plate 43 slides horizontally in the installation cavity 9 of the installation frame 41. The adjustment plate 43 has a square structure, and the side of the adjustment plate 43 relative to the first embedded part 3 abuts against the surface of the first embedded part 3, and the other three sides of the adjustment plate 43 abut against the inner wall of the installation frame 41 respectively.

[0052] The extension seat 42 and the guide seat 45 are both fixed to the side where the installation frame 41 and the column reinforcement frame 8 are against each other. The extension seat 42 and the guide seat 45 are both cylindrical with the axis extending in the horizontal direction. The axes of the extension seat 42 and the guide seat 45 are parallel to each other and are of equal length. The extension seat 42 and the guide seat 45 are distributed up and down in the vertical direction. The extension seat 42 is farther away from the relative first embedded part 3 than the guide seat 45. When the installation frame 41 and the column reinforcement frame 8 are against each other, the extension seat 42 and the guide seat 45 are both located in the space enclosed by the column reinforcement frame 8 and face the second embedded part 4 on the other side of the column 2.

[0053] An extension cavity 22 communicating with the installation cavity 9 is coaxially formed on the extension seat 42, and a guide cavity 23 communicating with the installation cavity 9 is coaxially formed on the guide seat 45. One end of the adjustment sleeve 44 is coaxially threadedly connected to the extension cavity 22 of the extension seat 42, and the other end of the adjustment sleeve 44 is rotatably connected to the adjustment plate 43. One end of the guide sleeve 46 slides in the guide cavity 23 of the guide seat 45 along the axial direction of the guide seat 45, and the other end of the guide sleeve 46 is fixed to the adjustment plate 43. The adjustment sleeve 44 and the guide sleeve 46 are of equal length, and the ends of the adjustment sleeve 44 and the guide sleeve 46 away from the column reinforcement frame 8 are flush with the side of the adjustment plate 43 away from the column reinforcement frame 8.

[0054] After the column 2 is cast, the side of the mounting frame 41 away from the column reinforcement frame 8 is flush with the surface of the column 2. Rotating the adjustment sleeve 44 can make the adjustment sleeve 44 move axially along the extension seat 42. Under the guiding action of the guide sleeve 46 and the guide seat 45, the adjustment plate 43 is driven to move axially along the extension seat 42 in the mounting frame 41 to adjust the position of the adjustment plate 43 so that the distance between the two adjustment plates 43 in the node unit 7 adapts to the installation requirements of the constraint support body 6.

[0055] Reference Figure 5 and Figure 6 In order to drive the movement of the adjustment sleeve 44, the adjustment member 10 is detachably connected to the adjustment sleeve 44. Specifically, the adjustment member 10 includes an adjustment rod 101, a guide block 102 and a limit ring 103. The adjustment rod 101 is cylindrical, the guide block 102 is fixed to the outer wall of one end of the adjustment rod 101, and the limit ring 103 is threadedly connected to the outer wall of the adjustment rod 101. The adjustment sleeve 44 is coaxially provided with a sliding groove 11 that passes through the end of the adjustment sleeve 44 away from the column reinforcement frame 8, and the sliding groove 11 allows the adjustment rod 101 to slide in the adjustment sleeve 44.

[0056] The adjustment sleeve 44 is provided with a first limiting groove 12 on the inner wall of the sliding groove 11 for the guide block 102 to slide, and the first limiting groove 12 penetrates the end of the adjustment sleeve 44 away from the column reinforcement frame 8 along the axial direction of the adjustment sleeve 44. The adjustment sleeve 44 is provided with a second limiting groove 13 at the end of the first limiting groove 12 close to the column reinforcement frame 8, and the second limiting groove 13 extends circumferentially along the adjustment sleeve 44. The adjustment sleeve 44 is provided with a third limiting groove 14 at the end of the second limiting groove 13 away from the first limiting groove 12, and the third limiting groove 14 extends along the axial direction of the adjustment sleeve 44 in a direction away from the column reinforcement frame 8, and the third limiting groove 14 does not penetrate the end of the adjustment sleeve 44 away from the column reinforcement frame 8.

[0057] When the guide block 102 moves in the first limiting groove 12 to the end of the first limiting groove 12 close to the column reinforcement frame 8, the adjusting rod 101 is rotated to drive the guide block 102 to move into the second limiting groove 13. When the guide block 102 is located at the end of the second limiting groove 13 away from the first limiting groove 12, the adjusting rod 101 is pulled in the direction away from the column reinforcement frame 8, which can drive the guide block 102 to press into the third limiting groove 14. And when the guide block 102 abuts against the end of the third limiting groove 14 away from the column reinforcement frame 8, the limiting ring 103 is threadedly moved to abut against the side of the adjusting sleeve 44 away from the column reinforcement frame 8, which can limit the guide block 102 from sliding further, so that the adjusting rod 101 and the adjusting sleeve 44 are relatively positioned. At this time, rotating the adjusting rod 101 can drive the adjusting sleeve 44 to rotate, so that the adjusting sleeve 44 moves in the inner thread of the extension seat 42.

[0058] Reference Figure 4 and Figure 5 In addition, a casting space is formed between a side of the adjustment plate 43 close to the column reinforcement frame 8 and the inner wall of the installation frame 41, and the guide sleeve 46 has a through groove 20 that penetrates the end of the guide sleeve 46 away from the column reinforcement frame 8, and leakage holes 21 are distributed on the end of the adjustment sleeve 44 away from the column reinforcement frame 8 and the guide sleeve 46. The leakage holes 21 on the adjustment sleeve 44 connect the sliding groove 11 with the casting space, and the leakage holes 21 on the guide sleeve 46 connect the casting space with the through groove 20.

[0059] After the position adjustment of the adjustment plate 43 is completed, the adjustment rod 101 is removed from the adjustment sleeve 44, and the portion between the adjustment sleeve 44 and the guide sleeve 46 at the bottom can be used as a grouting port, and the portion at the top can be used as a grouting outlet. Concrete is poured from the grouting port into the casting space to form a reinforced concrete structure in the casting space to further support and position the adjustment plate 43.

[0060] Reference Figure 3 and Figure 4In order to improve the stability of the mounting frame 41 when the column formwork 24 is cast, a rotating cylinder 16 and a guide cylinder 17 are arranged between two opposite second embedded parts 4 of the same column 2. The rotating cylinder 16 and the guide cylinder 17 are both made of steel. The rotating cylinder 16 and the guide cylinder 17 are located between the mounting frames 41 of the two opposite second embedded parts 4, and the rotating cylinder 16 and the guide cylinder 17 are both hollow cylindrical structures.

[0061] The rotating cylinder 16 includes a positive rotation part 161 and a negative rotation part 162. The inner walls of the positive rotation part 161 and the negative rotation part 162 are both provided with internal threads, and the internal threads on the positive rotation part 161 and the negative rotation part 162 are in opposite directions. The two extension seats 42 on the second embedded parts 4 are respectively threadedly connected with the positive rotation part 161 and the negative rotation part 162.

[0062] The extension seats 42 on the two relative second embedded parts 4 are respectively threadedly connected to the positive rotation part 161 and the reverse rotation part 162, and the guide seats 45 on the two relative second embedded parts 4 coaxially slide in the same guide cylinder 17, and the rotating cylinder 16 between the two relative mounting frames 41 is parallel to the axis of the guide cylinder 17, so that by rotating the rotating cylinder 16, the two relative second embedded parts 4 can move towards or away from each other under the guiding action of the guide cylinder 17 to adjust the distance between the two relative mounting frames 41.

[0063] Reference Figure 4 Furthermore, a connection seat 18 is connected to the outer wall of the middle part of the guide cylinder 17, and the connection seat 18 is made of steel. The connection seat 18 includes a connection portion 181 and a rotating ring 182. The connection portion 181 is fixed to the outer surface of the guide cylinder 17 and extends toward the rotating cylinder 16. The rotating ring 182 is fixed to the end of the connection portion 181 away from the guide cylinder 17. A rotating ring groove for the rotating ring 182 to be inserted is coaxially provided on the outer wall of the middle part of the rotating cylinder 16, so that the rotating cylinder 16 and the guide cylinder 17 are relatively limited, thereby improving the stability between the rotating cylinder 16 and the guide cylinder 17.

[0064] In addition, the rotating cylinder 16 and the guide cylinder 17 are both provided with connecting holes 19 connected to their own inner cavities. When the column formwork 24 is grouting, the concrete slurry can enter the rotating cylinder 16 and the guide cylinder 17 through the connecting holes 19, thereby improving the stability of the rotating cylinder 16 and the guide cylinder 17 and making the rotating cylinder 16 and the guide cylinder 17 less likely to bend under force.

[0065] Reference Figure 7 and Figure 8When the column formwork 24 is constructed, the two opposite second embedded parts 4 are first matched with the rotating cylinder 16 and the guide cylinder 17, and then the vertical steel bars 81 and the stirrups 82 are arranged, so that the rotating cylinder 16 and the guide cylinder 17 are located in the column reinforcement frame 8, and the upper and lower stirrups 82 adjacent to the extension seat 42 are respectively abutted against the upper and lower sides of the connecting seat 18, and the upper and lower stirrups 82 adjacent to the guide seat 45 are respectively abutted against the upper and lower sides of the guide seat 45. And by rotating the rotating cylinder 16, the two installation frames 41 can be respectively pressed against the opposite sides of the column reinforcement frame 8, so that the column reinforcement frame 8 and the installation frame 41 are relatively positioned.

[0066] Reference Figure 5 and Figure 8 When the adjusting rod 101 cooperates with the adjusting sleeve 44, the end of the adjusting rod 101 away from the column reinforcement frame 8 always extends out of the outside of the installation frame 41. The part of the adjusting rod 101 located outside the installation frame 41 is detachably threaded with a butterfly nut 15.

[0067] After the column reinforcement frame 8 and the installation frame 41 are relatively positioned, a column template 24 that encloses the installation frame 41 and the column reinforcement frame 8 needs to be erected outside the installation frame 41, and a through hole opposite to the adjusting rod 101 is opened on the column template 24 so that the adjusting rod 101 can pass through the column template 24, and then the butterfly nut 15 is matched with the adjusting rod 101 and threadedly moved to be tight against the outer wall of the main template, so that the column template 24 is locked between the butterfly nut 15 and the installation frame 41, so as to position the column template 24 while increasing the sealing between the column template 24 and the installation frame 41, so that concrete is not easy to enter the installation cavity 9 during pouring.

[0068] The implementation principle of a steel tube concrete node seismic resistant structure in an embodiment of the present application is: when the column 2 is cast, the rotating cylinder 16 is rotated to adjust the distance between the two installation frames 41, and then the column reinforcement frame 8 is installed, and then the column template 24 is enclosed by the installation frame 41 and the column reinforcement frame 8, so that the adjusting rod 101 passes through the column template 24 and the butterfly nut 15 is threadedly moved on the adjusting rod 101 to be tightly pressed against the outer wall of the column template 24, and then concrete is cast in the space enclosed by the column template 24 to form the column 2.

[0069] After the column 2 is formed, the butterfly nut 15 and the column template 24 are removed, and the distance between the two adjustment plates 43 in the node unit 7 is measured. The adjustment rod 101 is rotated to drive the adjustment sleeve 44 to move in the inner thread of the extension seat 42 to adjust the position of the adjustment plate 43 in the installation frame 41. When the distance between the two adjustment plates 43 is adjusted to a predetermined value, the adjustment rod 101 is removed, and concrete is poured into the pouring space through the adjustment sleeve 44 and the guide sleeve 46.

[0070] After the concrete in the pouring space is formed, the connecting plate 5 is welded to the relative adjusting plate 43 and the first embedded part 3, and then the restraining support body 6 is welded to the connecting plate 5, and the installation of the restraining support body 6 is completed.

[0071] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
