Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a basement circular pipe column separation support device and an installation method thereof. Background Art

[0002] In recent years, with the rapid development of super-high-rise buildings and their constant renewal of the skyline, the application of steel structures in these buildings has become increasingly widespread. The connection between the steel structure and the foundation is typically achieved through anchor bolts. The diameter and number of anchor bolts increase with height, especially in super-high-rise steel structures exceeding 300 meters. The basements are deep, and the cross-sections of the steel columns are particularly large, making the connection between them and the concrete base slab particularly critical. In such cases, oversized anchor bolt groups are generally used to maintain joint reliability. These anchor bolts are high in strength, diameter, and number, and the overall weight of the anchor bolt group is considerable. Therefore, very high requirements are placed on the installation support device and installation method of the anchor bolt group.

[0003] For the extra-large anchor bolt groups of giant circular pipe columns in ultra-deep basements, the shortcomings of traditional anchor bolt group installation support devices and installation methods have gradually become apparent. The support measures require a large amount of investment and are relatively costly, and are generally composed of a support frame + positioning plate. The anchor bolt group is usually installed in bulk in situ, that is, a single anchor bolt is installed on the basement floor anchor bolt bracket. For ultra-deep basements, the basement is deep, and the in-situ bulk lifting times are many and the lifting distance is long, resulting in low anchor bolt installation efficiency and accuracy. At the same time, the in-situ bulk installation of anchor bolts and the steel bars form an intersecting operation. There is a technical gap between the anchor bolt bracket and the steel bars, and they have to wait for each other. Only after the overall installation of the anchor bolt bracket is completed can the anchor bolts be installed in bulk in situ. The anchor bolt installation cannot be inserted in advance for construction, and the construction period is relatively long. Welding is adopted between the anchor bolt and the positioning plate, which damages the high-strength anchor bolt base material, reduces the mechanical properties, and increases the structural safety risk. The anchor bolt and the positioning plate are fixed with upper and lower double nuts, which greatly increases the anchor bolt threading length, the number of nuts input, and the installation and adjustment workload of workers, increasing cost investment and reducing work efficiency.

[0004] For the giant circular pipe column and extra-large anchor bolt groups in ultra-deep basements, how to insert them into the construction site in advance, reduce support measures and improve installation efficiency has become an urgent problem to be solved. Summary of the Invention

[0071] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0074] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0075] The following combination Figures 1 to 18 , describing embodiments of the present invention.

[0076] According to an embodiment of the present invention, on the one hand, a basement circular pipe column separate support device is provided, comprising:

[0077] The support frame assembly 3 is adapted to be at least partially received within the bottom layer of steel bars 12;

[0078] The assembly frame group 5 is assembled separately from the support frame group 3. The support frame group 3 is suitable for supporting the assembly frame group 5, and the top of the assembly frame group 5 is suitable for at least partially being installed in the top steel bar 11. The area where the assembly frame group 5 passes through the top steel bar 11 is suitable for connecting to the circular pipe column 4.

[0079] The prefabricated base frame assembly 2 is suitable for supporting the assembling frame assembly 5 before the assembling frame assembly 5 is assembled with the supporting frame assembly 3 so as to assemble the assembling frame assembly 5 .

[0080] The separate support device for circular tubular columns in basements provided by an embodiment of the present invention divides the support device installed at the construction site into two parts, namely, a support frame group 3 and an assembly frame group 5. Furthermore, by setting up a prefabricated base frame group 2 near the storage yard, the assembly frame group 5 can be pre-assembled, facilitating the insertion of anchor bolts during construction. This allows the support frame group 3 and the assembly frame group 5 to be constructed simultaneously. After the assembly of the two is completed, the assembly frame group 5 is hoisted as a whole above the support frame group 3 and the two are connected and fixed. This achieves a fast and efficient installation process, reduces on-site work time, improves construction efficiency, and achieves efficient installation, a short construction period, and low costs.

[0081] It should be noted that in order to ensure that the assembly frame assembly 5 can fully adapt to the support frame assembly 3 after assembly is completed, and facilitate subsequent precise docking, when designing the prefabricated base frame assembly 2, it is necessary to follow the design drawings of the support frame assembly 3 to ensure that the dimensions of the prefabricated base frame assembly 2 match those of the support frame assembly 3. At the same time, the stability of the prefabricated base frame assembly 2 must also be strictly considered to ensure that the assembly frame assembly 5 will not shift or tilt during the assembly process, thereby ensuring the stability and safety of the entire support device.

[0082] In some embodiments, the support frame assembly 3 includes a bottom plate support frame 31 adapted to be supported on the bottom of the assembly frame assembly 5; the bottom plate support frame 31 includes:

[0083] Multiple bottom plate columns 311, each of which extends vertically and is disposed around the bottom of the assembly frame set 5;

[0084] The bottom plate cross beam 313 sequentially connects the plurality of bottom plate columns 311 along the circumferential direction, and the bottom plate cross beam 313 includes multiple layers spaced apart vertically.

[0085] In this embodiment, the bottom plate cross beam 313 includes multiple layers arranged at intervals along the vertical direction. The multi-layer design of the bottom plate cross beam 313 enhances the stability of the overall structure and ensures that it can withstand a large load during the construction process.

[0086] In some embodiments, the prefabricated base frame assembly 2 includes a prefabricated base frame 21;

[0087] The prefabricated base frame 21 comprises:

[0088] A plurality of base columns 214 , where the distribution positions of the plurality of base columns 214 correspond to the bottom plate columns 311 ;

[0089] The base crossbeam 211 is connected to a plurality of base columns 214 in sequence along the circumferential direction, and the distribution position of the base crossbeam 211 corresponds to the bottom plate crossbeam 313;

[0090] Embedded plate 212, disposed at the bottom of base column 214;

[0091] The embedded bolts 213 are adapted to pass through the embedded plate 212 and be fixedly connected to the prefabricated foundation of the storage yard.

[0092] By making the distribution positions of multiple base columns 214 correspond to the bottom plate columns 311, and the distribution positions of the base beams 211 correspond to the bottom plate beams 313; it is ensured that the prefabricated base frame group 2 and the support frame group 3 are highly compatible in structure, which facilitates the precise docking of the assembled frame group 5, improves the installation accuracy, further optimizes the construction process, reduces the error rate, and ensures the quality and safety of the project.

[0093] At the same time, the fixing effect of the embedded bolts 213 effectively prevents any slight displacement during the assembly process, ensuring efficient and accurate construction.

[0094] In some embodiments, the support frame group 3 further includes an oblique support 32, which is arranged around the circumference of the assembly frame group 5 and is suitable for supporting the outer periphery of the assembly frame group 5;

[0095] The base plate support frame 31 includes multiple diagonal support columns 312, which all extend vertically and are horizontally arranged on the periphery of the area surrounded by the multiple base plate columns 311; the diagonal support 32 is suitable for supporting between the diagonal support columns 312 and the assembly frame group 5.

[0096] The design of diagonal braces 32 not only enhances the overall stability of the assembled frame assembly 5 but also disperses structural stress through multi-point support, effectively preventing deformation or overturning due to external forces. Furthermore, the synergistic effect of diagonal brace columns 312 and baseplate columns 311 further enhances the compressive strength of the supporting frame assembly 3, ensuring excellent load-bearing capacity even in complex construction environments.

[0097] In some embodiments, the prefabricated base frame assembly 2 further includes a prefabricated support frame 22;

[0098] The prefabricated support frame 22 comprises:

[0099] A plurality of prefabricated support columns 223, wherein the plurality of prefabricated support columns 223 extend vertically, and one end of the prefabricated support column 223 is fixedly connected to the base beam 211;

[0100] The cantilever beam 222 is connected to the other end of the prefabricated support column 223. The cantilever beam 222 extends in the horizontal direction and is suitable for supporting the assembly frame group 5. The cantilever beam 222 is provided with an elongated hole 2221.

[0101] The adjusting beam 221 is movably connected to one end of the cantilever beam 222 away from the prefabricated supporting column 223. The adjusting beam 221 is provided with a fixing hole 2211. The fixing hole 2211 is connected to the elongated hole 2221 through an adjusting bolt 224 to horizontally adjust the adjusting beam 221. The adjusting beam 221 is suitable for adjusting the horizontal position of the assembly frame group 5.

[0102] Combine Figure 7 As shown, the cantilever beam 222 extends in the horizontal direction. The cantilever beam 222 is suitable for supporting the bottom of the ring plate 511 located at the lowest layer and forming a stable support point to ensure the stability of the assembly frame set 5 in the vertical direction.

[0103] At the same time, by movably connecting the adjustment beam 221 to one end of the cantilever beam 222 away from the prefabricated support column 223, the cantilever beam 222 is provided with a long hole 2221 to adjust the horizontal position of the adjustment beam 221, thereby achieving precise positioning of the assembly frame group 5. The adjustment beam 221 can be flexibly adjusted according to actual needs to ensure the horizontal alignment of the assembly frame group 5 so as to accurately position the ring plate 511.

[0104] In some embodiments, the assembly frame set 5 includes an assembly frame 51, which includes multiple layers of ring plates 511. The multiple layers of ring plates 511 are arranged at intervals along the vertical direction. Adjacent ring plates 511 are connected via main columns 512, and the main columns 512 are evenly distributed along the circumference.

[0105] The multiple layers of ring plates 511 are arranged at intervals along the vertical direction, and the adjacent ring plates 511 are connected via the main columns 512 so as to realize the vertical increase of the assembly frame 51. At the same time, the uniform distribution of the main columns 512 ensures the overall rigidity and stability of the assembly frame 51.

[0106] In some embodiments, the ring plate 511 is provided with anchor holes 5111 , and the anchor holes 5111 of the multiple layers of ring plates 511 are arranged in a vertically aligned manner;

[0107] The assembly frame set 5 also includes an anchor bolt group 52, which includes:

[0108] Anchor rod 522, adapted to pass through anchor hole 5111 and connect the multi-layer ring plate 511;

[0109] The top nut 521 is adapted to securely connect the anchor rod 522 to the uppermost ring plate 511;

[0110] The end plate 523 is disposed below the bottom ring plate 511. The main column 512 is connected between the bottom ring plate 511 and the end plate 523. The end plate 523 also has anchor holes 5111.

[0111] The bottom nut 524 is suitable for fixing the anchor rod 522 to the end plate 523 .

[0112] The vertical locking of the multi-layered ring plate 511 is ensured by the penetration connection of the anchor rod 522 and the fastening of the top nut 521 and the bottom nut 524 .

[0113] As an example, 36 anchor rods 522 are arranged on the inner and outer rings of the ring plate 511. Each anchor rod 522 has a diameter of 60 mm and is made of GLG850. The nut areas at both ends need to be threaded in the factory.

[0114] The end plate 523 is a steel plate, which is bolted to the anchor rod 522. An anchor hole is opened at the position where the anchor rod 522 passes through the end plate; the bottom nut 524 can be set on the upper and lower sides of the end plate 523, and the elevation is adjusted through the threaded area and then locked to form a fixed connection between the anchor rod 522 and the end plate 523.

[0115] Similarly, the top nuts 521 can be set on the upper and lower sides of the uppermost ring plate 511, and their main functions are to adjust the elevation and support the load of the upper steel column.

[0116] Since the anchor rods 522 in the anchor bolt group 52 are made of high-strength material, the ring plate 511 is not allowed to be welded to the high-strength anchor rods 522 . Therefore, bolts are used to fasten the ring plate 511 to ensure that there is no connection between the two.

[0117] In some embodiments, the assembly frame set 5 further includes a lifting lug 53 , which is installed on the uppermost ring plate 511 .

[0118] The lifting lugs 53 can be welded to the topmost ring plate 511. After the anchor bolt group is assembled, the lifting equipment lifts the lifting lugs 53 to lift the entire anchor bolt group to the installation location for docking with the support frame assembly 3. The number of lifting lugs 53 can be multiple and evenly distributed to ensure uniform force during lifting and avoid local stress concentration.

[0119] According to an embodiment of the present invention, in another aspect, a method for installing a basement circular pipe column separate support device is provided, which is applied to the above-mentioned basement circular pipe column separate support device; the installation method comprises:

[0120] According to the design drawings of the support frame group 3, the prefabricated base frame group 2 is assembled in the yard area;

[0121] After the assembly is completed, the assembly frame group 5 is assembled on the prefabricated base frame group 2;

[0122] While the prefabricated base frame group 2 is being assembled, the support frame group 3 is being assembled at the construction site;

[0123] After the assembly of the assembly frame group 5 and the supporting frame group 3 is completed, the assembly frame group 5 is hoisted to a predetermined position of the supporting frame group 3, and the two are fixed.

[0124] The installation method of the basement circular pipe column separate support device provided by the embodiment of the present invention divides the support device installed at the construction site into two parts, namely, the support frame group 3 and the assembly frame group 5. By setting up a prefabricated base frame group 2 near the yard, the assembly frame group 5 can be assembled in advance, which facilitates the early insertion of anchor bolts during construction, so that the support frame group 3 and the assembly frame group 5 can be constructed simultaneously. After the two are assembled separately, the assembly frame group 5 is hoisted as a whole above the support frame group 3 and the two are connected and fixed, thereby achieving a fast and efficient installation process. There is no need to wait for the assembly work of the support frame group 3 to be completed before installing the assembly frame group 5, which reduces on-site operation time, improves construction efficiency, and achieves efficient installation, short construction period, and low cost.

[0125] It should be noted that the prefabricated base frame group 2 is assembled in the basement top plate yard area. Correspondingly, the assembly frame group 5 is also assembled as a whole in the basement top plate yard area, and the construction site of the support frame group 3 is the basement floor area, where there is a high drop from the basement top plate to the basement floor, for example, the distance can reach 42.5m. Therefore, after the assembly frame group 5 is assembled, it needs to be hoisted as a whole from the basement top plate yard area to the basement floor area, and the two need to be connected and fixed, so as to achieve a fast and efficient installation process.

[0126] According to the design drawings of the support frame group 3, the prefabricated base frame group 2 is assembled in the yard area; specifically, the points can be marked out and holes can be drilled according to the design drawings, and after the embedded bolts 213 are installed, the embedded plates 212 can be installed, and the anchor bolt group assembly work can be carried out in advance to improve work efficiency and shorten the construction period.

[0127] In some embodiments, when assembling the support frame group 3 at the construction site, the bottom plate columns 311 and the diagonal support columns 312 are first positioned and installed, and then the bottom steel bars 12 are tied, and then the bottom plate cross beams 313 are welded and fixed to the bottom plate columns 311.

[0128] After the assembly frame group 5 and the support frame group 3 are assembled, the top steel bars 11 can be tied on the assembly frame group 5. Before tying, the lugs 53 need to be cut off to avoid collision with other top steel bars 11.

[0129] The round tube column 4 is then installed to the area where the assembly frame set 5 passes through the top layer of steel bars 11.

[0130] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the present invention.
