Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and relates to a multiple conversion high-rise structure system and a construction control method. Background Art

[0002] In the development of modern cities, high-rise buildings are not only an important part of the city skyline, but also a manifestation of urban functions and aesthetics. With the increasing demand for the use of large spaces at the bottom of buildings and the pursuit of aesthetics, the design of high-rise buildings faces more severe challenges. These challenges are not only reflected in the appearance of the building, but also go deeper into the structural system of the building, forcing architects and engineers to ensure the safety and stability of the structure while meeting aesthetic and functional requirements.

[0003] The demand for large spaces at the bottom of buildings is usually related to commercial, cultural or public activity spaces. In order to ensure the transparency of the bottom floors of the building, the outer frame outside the core tube needs to minimize the number of structural components, which will inevitably lead to a large number of vertical components of the outer frame being unable to land, discontinuous vertical load transfer, and indirect force transmission. In order to adapt to these challenges, engineers have developed a variety of conversion structure systems, such as truss conversion layers, beam conversion layers, box-shaped conversion layers, etc., to achieve the openness and flexibility of large spaces at the bottom of the building. The innovation of these conversion structure systems not only solves the demand for large spaces at the bottom of the building, but also provides new possibilities for the structural design of high-rise buildings. These conversion structure systems effectively transfer the load of the upper structure to the lower structure to meet the requirements of the building by setting up conversion layers on one or some floors of the building, but the conversion structure system is usually rigidly connected, and it is difficult to achieve precise control of structural performance during construction.

DETAILED DESCRIPTION

[0037] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0038] like Figure 1-Figure 7 A multi-conversion high-rise structural system shown includes four independent columns 1 arranged outside the core tube 2. The four independent columns 1 play a major supporting role in the structural system. A common bottom conversion truss 4 is designed on the top of the four independent columns 1. The bottom conversion truss 4 not only connects the four independent columns 1, but also has an umbrella-shaped conversion unit 13 connected to the core tube 2 arranged inside it to achieve structural conversion and force transmission.

[0039] On the top of the bottom conversion truss 4, multiple layers of outer frame structures 6 and conversion trusses are sequentially arranged until the construction height. Taking the three-layer conversion truss as an example, multiple outer frame structures 6 are arranged on the top of the bottom conversion truss 4. These outer frame structures 6 not only enhance the stability of the structure, but also provide connection points for subsequent conversion trusses. In particular, between the two outer frame structures 6 in the middle, a middle conversion truss 5 connected to the core tube 2 is arranged. And on the top of the uppermost outer frame structure 6, a top conversion truss 7 connected to the core tube 2 is arranged. Both the middle conversion truss 5 and the top conversion truss 7 are provided with multiple limit steels 8 used in conjunction with the core tube 2. Multiple cables 12 are arranged on these limit steels 8, and the other end of the cable 12 is adjustably connected to the core tube 2. This design allows the length and angle of the cable 12 to be adjusted as needed, thereby changing the direction of force application and improving the flexibility and stability of the structure.

[0040] In order to achieve accurate installation and horizontal adjustment of the above structure, a plurality of temporary support frames 3 are set on the ground. The tops of these temporary support frames 3 are provided with lifters 25 that interfere with the bottom conversion truss 4. The height of the lifters 25 is adjustable, so that the horizontal positions of the bottom conversion truss 4, the middle conversion truss 5, the outer frame structure 6 and the top conversion truss 7 can be accurately adjusted to ensure the stability and accuracy of the entire structural system.

[0041] In order to firmly connect the temporary support frame 3 with the independent column 1, four clamping mechanisms are provided on the independent column 1. These clamping mechanisms are used in conjunction with the lifter 25 to ensure the stability and reliability of the temporary support frame 3 in the structural system.

[0042] Two sets of embedded seats 9 corresponding to the top conversion truss 7 and the middle conversion truss 5 are fixedly arranged on the outside of the core tube 2. A sliding seat 10 is slidably arranged inside the embedded seat 9, and the other ends of multiple cables 12 are connected to the sliding seat 10. At least two first bolts 11 are penetrated through one side of the sliding seat 10, and multiple threaded holes matching the first bolts 11 are opened on one side of the embedded seat 9. In this way, the connection point between the cable 12 and the core tube 2 can be accurately adjusted by a jack, and fixed by the first bolt 11 after the adjustment is completed, thereby further improving the stability and flexibility of the structure.

[0043] The specific structure of the temporary support frame 3 includes a plurality of tower bodies 14 that are sequentially plugged in from bottom to top. The four corners of the bottom of each tower body 14 are rotatably provided with first positioning pins 15, and the four corners of the top are provided with limiting holes corresponding to the first positioning pins 15. In this way, two adjacent tower bodies 14 can be conveniently spliced ​​or disassembled by inserting or pulling out the first positioning pins 15. At the same time, a limiting piece is also provided on the first positioning pin 15, which is used to limit the position between the two tower bodies 14 to ensure that the connection between them is firm and reliable.

[0044] The specific implementation method of the limiting member is as follows: a hexagonal block 16 is rotatably provided at the four corners of the bottom of the tower body 14, and a first positioning pin 15 is fixedly provided on the hexagonal block 16. A limiting column 17 is fixedly provided on the outer wall of the first positioning pin 15, and an L-shaped slot 18 used in conjunction with the limiting column 17 is provided at the four corners of the top of the bottom conversion truss 4. When the two tower bodies 14 are plugged in, the limiting column 17 can be inserted into the L-shaped slot 18 by rotating the hexagonal block 16, thereby achieving the limiting and fixing of the tower body 14.

[0045] The specific structure of the lifter 25 includes a mounting base 34 arranged at the top of the upper tower body 14. Two superimposed first wedges 26 are arranged at the top of the mounting base 34, and a second rotating base 39 is arranged between the two first wedges 26. A guide bar 37 is slidably provided through the middle of the two first wedges 26, and the two guide bars 37 are respectively fixed at the top and bottom of the second rotating base 39. Two double-headed screws 27 are rotatably provided through one side of the second rotating base 39, and two second wedges 40 are threadedly provided on the outer walls of the two double-headed screws 27. The two second wedges 40 are respectively located on both sides of the second rotating base 39 and abut against the two first wedges 26. By rotating the double-headed screw 27, the second wedge 40 can be moved along the double-headed screw 27 and abut against the first wedge 26, thereby realizing the height adjustment of the lifter 25.

[0046] In order to protect the double-headed screw rods 27 and facilitate operation, first guard plates 28 are sleeved on both ends of the two double-headed screw rods 27. At the same time, guide rods 29 are fixedly provided on both sides of the second rotating seat 39, and second guard plates 31 are slidably sleeved on the outer wall of the guide rods 29. First rotating seats 32 are fixedly provided at both ends of the second guard plate 31 and the first guard plate 28, and a connecting rod 33 is rotatably provided between the two corresponding first rotating seats 32. The outer wall of the guide rod 29 is also sleeved with a spring 30, and the two ends of the spring 30 are respectively fixedly connected to the outer wall of one end of the guide rod 29 and one side of the second guard plate 31. In this way, when it is necessary to adjust the height of the lifter 25, the first guard plate 28 can be pushed first to expose the hexagonal notch 43 of the double-headed screw rod 27, and then the double-headed screw rod 27 can be rotated with a wrench for adjustment. After the adjustment is completed, the first guard plate 28 is loosened, and the elastic force of the spring 30 will reset the second guard plate 31 and drive the first guard plate 28 to cover the hexagonal notch 43, thereby protecting the double-headed screw 27 from damage and accidental rotation due to external force.

[0047] In order to facilitate the limiting and fixing of the two second wedge blocks 40, second positioning pins 41 are fixedly provided on both sides of the second wedge blocks 40, and a plurality of insertion holes 42 for use with the second positioning pins 41 are provided on the inner side of the second guard plate 31. When the second wedge block 40 is moved to a specified position, the position of the second wedge block 40 can be fixed by inserting the second positioning pins 41 into the corresponding insertion holes 42.

[0048] The specific implementation method of the clamping mechanism is: two clamping rings 19 are set on the outer wall of the independent column 1, and the two clamping rings 19 are fixedly connected by a nut ring 21 and a second bolt 20. An extension frame 22 is fixedly provided on the outer wall of the clamping ring 19, and two limit bars 23 are fixedly provided on the top of one end of the extension frame 22. A plurality of positioning grooves 24 are provided on one side of the limit bar 23, and the same positioning bar 36 is clamped in two corresponding positioning grooves 24. The same extension bar 35 is fixedly provided between the positioning bar 36 and the corresponding second guard plate 31. In this way, when the temporary support frame 3 rises to the specified position, the positioning bar 36 can be inserted into the corresponding positioning groove 24, and the positioning bar 36 can be connected to the second guard plate 31 using the extension bar 35, thereby realizing a firm connection between the clamping mechanism and the lifter 25.

[0049] In particular, two adjacent extension frames 22 are designed to be at right angles and correspond to the temporary support frame 3. This not only improves the stability and reliability of the clamping mechanism, but also makes the temporary support frame 3 more evenly and reasonably distributed in the structural system, further improving the stability and bearing capacity of the entire structural system.

[0050] During the construction and control of the multi-conversion high-rise structure system, first, the double-headed screw 27 is rotated to drive the first wedge 26 to move up and down, and the horizontal position of the bottom conversion truss 4 is adjusted. During the adjustment of the bottom conversion truss 4, the middle conversion truss 5 and the top conversion truss 7 above are adjusted in turn through the multiple outer frame structures 6;

[0051] After the adjustment is completed, the cable 12 is tightened, and the jack is placed on the corresponding limit steel 8 according to the force condition, and the jack is pressed to drive the sliding seat 10 to move upward on the embedded seat 9, so as to adjust the position of one end of the cable 12 on the core tube 2, adjust the internal force distribution, and reduce the deformation and force of the key point. After the adjustment is completed, the first bolt 11 is passed through the sliding seat 10 and screwed into the embedded seat 9 to lock the cable 12;

[0052] When the temporary support frame 3 needs to be unloaded after the construction is completed, the lifter 25 above the temporary support frame 3 is first removed, specifically: push the first guard plate 28, and during the movement of the first guard plate 28, the second guard plates 31 on both sides can be driven away from each other through the connecting rod 33, the movement of the second guard plate 31 can drive the extension bar 35 to move, and the movement of the extension bar 35 can drive the positioning bar 36 to move, so that the positioning bar 36 is disengaged from the corresponding positioning groove 24, thereby releasing the connection between the lifter 25 and the independent column 1, and then the wrench is stuck in the hexagonal notch 43, and the two double-headed screws 27 are rotated in the opposite direction. The rotation of the double-headed screw 27 can drive the two second wedge blocks 40 to move away from each other. During the process of moving away, the upper first wedge block 26 can move downward under its own gravity until there is enough disassembly distance between the upper first wedge block 26 and the temporary support frame 3, and then the lifter 25 is removed from the tower body 14, and then the retaining ring 19 is removed from the independent column 1. Finally, multiple tower bodies 14 are disassembled in turn. During the disassembly process, the hexagonal block 16 is rotated by a wrench to drive the first positioning pin 15 to rotate. The rotation of the first positioning pin 15 can drive the limiting column 17 to move in the L-shaped slot 18 until the limiting column 17 moves to the corner of the L-shaped slot 18. At this time, the upper tower body 14 can be removed from the lower tower body 14, and the tower bodies 14 can be dismantled in turn using the above method.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
