[0002] Steel structures are buildings that use structural steel as their load-bearing structure. These structures are typically made up of beams, columns, trusses, and other components made of section steel and steel plates. Together with the roof, floor, and wall enclosures, they form the entire building.

DETAILED DESCRIPTION

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0042] See also Figure 1-11 , a beam-column structure for ultra-long span steel structure buildings, comprising:

[0043] Support column 1, the top and bottom ends of the support column 1 are fixedly connected to the matching lock plate A2, and both ends of the matching lock plate A2 are provided with matching lock holes A3;

[0044] The crossbeam mounting assembly 4 is arranged between the two support columns 1. The crossbeam mounting assembly 4 includes a vertical plate 5 and two horizontal plates 6. The two horizontal plates 6 are fixedly connected to the top and bottom ends of the vertical plates 5 respectively. The ends of the two horizontal plates 6 away from each other are fixedly connected with limit columns A7 adapted to the lock holes A3. Both sides of the vertical plates 5 are fixedly connected to limit columns B8. A stabilization assembly is also provided between the two horizontal plates 6.

[0045] The crossbeam body 9 has a locking plate B10 fixedly connected to both ends of the crossbeam body 9. The locking plate B10 has a locking hole B11 at a position corresponding to the limit column B8. The top and bottom ends of the crossbeam body 9 are fixedly connected to two stabilizing columns 12. The stabilizing component is used to position the support column 1 and the crossbeam body 9.

[0046] A locking assembly 13 is assembled at the connection of the two crossbeam bodies 9 and is used to splice the two crossbeam bodies 9;

[0047] In this embodiment, the support column 1 and the crossbeam body 9 are both I-beams, and their characteristics are as follows:

[0048] High strength: Since the cross-section of the I-beam is H-shaped, it has strong tensile and compressive resistance and can withstand large loads. At the same time, the I-beam has strong bending resistance and is suitable for various stress conditions.

[0049] Good stability: I-beams have good lateral stability and rigidity, and can effectively resist additional internal forces caused by external wind or vibration.

[0050] Combinability: I-beams can be flexibly combined with other types of steel structural components such as H-beams, angle steels, channel steels, etc. to form complex structural systems, making I-beams highly flexible and adaptable in actual engineering applications.

[0051] Facilitates industrialized production: Production is carried out quickly and efficiently through automated production lines, which greatly reduces construction costs and improves construction efficiency.

[0052] The stabilization component includes a positioning ear 14, a guide shaft 15, a positioning frame 16, a limiting frame 17, an eccentric plate A19 and an eccentric plate B20. The four end corners of the two horizontal plates 6 are fixedly connected to the positioning ear 14, and the middle part of the positioning ear 14 is rotatably connected to the guide shaft 15. Each guide shaft 15 is fixedly connected to the positioning frame 16 and the limiting frame 17. One end of the two guide shafts 15 at the same end angle is respectively fixedly connected to the eccentric plate A19 and the eccentric plate B20. A guide groove 21 is opened in the middle of the eccentric plate A19. The end of the eccentric plate B20 away from the guide shaft 15 is fixedly connected to a linkage column 22, and the linkage column 22 is also movably connected to the inside of the guide groove 21;

[0053] In detail, the positioning frame 16 and the limiting frame 17 are both "L"-shaped, and the tops of the positioning frame 16 and the limiting frame 17 are provided with anti-slip grooves, and the middle of the limiting frame 17 is provided with a waist hole 18. By utilizing the structural characteristics of the positioning frame 16 and the limiting frame 17, after the positioning frame 16 is flipped, it can contact the locking plate A2 in a larger range, and after the limiting frame 17 is flipped, the limiting frame 17 can limit the stabilizing column 12 inside the waist hole 18, thereby locking the position of the beam body 9. In this embodiment, the shape of the anti-slip groove can be:

[0054] Single tooth pattern: composed of a single protrusion, arranged in a tooth shape.

[0055] Double tooth pattern: It is composed of two mutually symmetrical protrusions, with a certain gap between each protrusion, which can significantly improve the anti-slip effect of the positioning frame 16 and the limiting frame 17.

[0056] Grid pattern: It is composed of a plurality of small protrusions, forming a grid-like structure, which can significantly improve the anti-slip effect of the positioning frame 16 and the limiting frame 17.

[0057] Petal-shaped pattern: It is composed of multiple inward-curved petal-shaped protrusions. This pattern can not only ensure a certain anti-slip effect, but also has a certain decorative effect.

[0058] Spiral pattern: Arranged in a spiral form, the distance and height between each spiral are specifically designed, which can significantly improve the anti-slip effect of the positioning frame 16 and the limiting frame 17;

[0059] Both ends of the interior of the vertical plate 5 are fixedly connected to a positioning seat 24, and the middle part of the positioning seat 24 is rotatably connected to a transmission shaft 25, and both ends of the transmission shaft 25 pass through the vertical plate 5. Both ends of the transmission shaft 25 are provided with a threaded receiving groove, and the threads of the two threaded receiving grooves are rotated in opposite directions. The inside of the two threaded receiving grooves is threadedly connected to a threaded rod 26, and one end of the threaded receiving groove located outside the threaded rod 26 is fixedly connected to a support ear 27, and one end of the support ear 27 is rotatably connected to a linkage rod 28, and the end of the linkage rod 28 away from the support ear 27 is rotatably connected to the corresponding eccentric plate B20;

[0060] In this embodiment, the transmission shaft 25 is rotated with the aid of a tool, and the two threaded receiving grooves with opposite thread rotation directions are arranged so that the two threaded rods 26 can follow the rotation of the transmission shaft 25 and move out of the threaded receiving grooves, thereby driving the support ear 27 to move. Moreover, since the linkage rod 28 is connected between the support ear 27 and the eccentric plate B20, when the support ear 27 moves, the eccentric plate B20 can be pulled by the linkage rod 28, and the eccentric plate A19 can be pulled by the displacement of the linkage column 22 inside the guide groove 21, thereby driving the corresponding two guide shafts 15 to rotate simultaneously.

[0061] Furthermore, a rotating shaft 23 is rotatably connected to the middle portion of one side of the eccentric plate B20, and one end of the linkage rod 28 away from the support ear 27 is fixedly connected to the corresponding rotating shaft 23. By setting the rotating shaft 23, the linkage rod 28 can be effectively assembled to ensure smooth linkage between the support ear 27 and the eccentric plate B20.

[0062] Furthermore, the top end of the support ear 27 is fixedly connected to a limit rod 29, and the end of the limit rod 29 close to the riser 5 is also slidably connected to the riser 5. The setting of the limit rod 29 can effectively guide the displacement of the support ear 27 to prevent the support ear 27 from rotating with the threaded rod 26. In this embodiment, the end of the limit rod 29 located inside the riser 5 is fixedly connected to a baffle for guiding the displacement of the limit rod 29 to prevent the limit rod 29 from detaching from the riser 5.

[0063] Furthermore, a threaded section 30 is provided at one end of the transmission shaft 25, and a stabilizing ring 31 is threadedly connected to the outer side of the threaded section 30. A gasket is fixedly connected to the end of the vertical plate 5 close to the stabilizing ring 31. By utilizing the connection between the stabilizing ring 31 and the threaded section 30, after the transmission shaft 25 rotates, the stabilizing ring 31 is rotated so that the stabilizing ring 31 moves on the threaded section 30 and fits tightly against the gasket, thereby increasing the friction force of the rotation of the transmission shaft 25.

[0064] The locking assembly 13 includes an assembly frame 32, a transmission screw A33, a transmission screw B34, a displacement plate 35 and a locking rod A36. The two ends of the assembly frame 32 are rotatably connected to the transmission screw A33 and the transmission screw B34. The end of the transmission screw A33 close to the transmission screw B34 is fixedly connected to the transmission screw B34, and the thread rotation direction of the transmission screw A33 and the transmission screw B34 are opposite. The outer sides of the transmission screw A33 and the transmission screw B34 are both threadedly connected to the displacement plate 35. The sides of the two displacement plates 35 close to each other are fixedly connected to the locking rod A 36 and locking plate B37, and the locking rod A36 and locking plate B37 are both snap-connected with the lock hole B11. The top and bottom ends of the assembly frame 32 are fixedly connected to linear guide rails 38. Each linear guide rail 38 is slidably connected to a transmission column 39. The end of the transmission column 39 away from the linear guide rail 38 is fixedly connected to a positioning clamping plate 40. The top and bottom of the two displacement plates 35 are both obliquely fixedly connected to conductive plates 41. The middle part of the four conductive plates 41 is provided with a conductive through groove 42, and the four transmission columns 39 are also movably connected to the inside of the four conductive through grooves 42;

[0065] In more detail, the transmission screw B34 is rotated, and the connection between the transmission screw B34 and the transmission screw A33 is coordinated, so that the transmission screw A33 can rotate with the transmission screw B34, and because the thread rotation direction of the transmission screw B34 is opposite to that of the transmission screw A33, when the transmission screw A33 and the transmission screw B34 rotate, the two displacement plates 35 can be driven to approach each other, so as to move the locking rod A36 and the locking plate B37 into the locking hole B11, so as to realize the splicing between the two crossbeam bodies 9 through the locking rod A36 and the locking plate B37, and cooperate with the connection between the displacement plate 35 and the conductive plate 41, when the displacement plates 35 approach each other, the transmission column 39 can be pulled through the conductive groove 42, so that the transmission column 39 drives the positioning clamping plate 40 to vertically displace under the limit of the linear guide rail 38, until the positioning clamping plate 40 contacts the crossbeam body 9, and the crossbeam body 9 is locked again;

[0066] In detail, the cross-section of the linear guide 38 is in the shape of an I-beam. A linear slider is fixedly connected to one end of the transmission column 39 connected to the linear guide 38. An I-shaped linear groove is provided in the middle of the linear slider. The linear slider is slidably connected to the linear guide 38 through the linear groove. The arrangement of the linear slider can effectively guide the displacement of the transmission column 39, thereby ensuring the contact effect between the positioning splint 40 and the crossbeam body 9.

[0067] Furthermore, one end of the locking rod A36 is fixedly connected to a card rod, and one end of the locking plate B37 is provided with a card slot, and the locking rod A36 is connected to the inside of the card slot through the card rod. By utilizing the setting of the card rod and the card slot, when the locking rod A36 and the locking plate B37 move into the matching lock hole B11, the card rod will synchronously move into the card slot, thereby enhancing the connection stability between the cross plate 6 and the locking plate B37. Example

[0068] See also Figure 1-11 Based on the first embodiment, this embodiment provides a construction method for a beam-column structure of a super-large span steel structure building, and the steps are as follows:

[0069] The first step is to lift the crossbeam mounting assembly 4 to the top of the support column 1 using a lifting device, and align the limit column A7 with the lock hole A3, and then move the limit column A7 into the lock hole A3;

[0070] In more detail, according to the original size of the steel structure building, the support column 1 and the cross beam body 9 are prefabricated, and the prefabricated support column 1 and cross beam body 9 are transported to the construction site, and then the support column 1 is lifted vertically by a crane, and then the support column 1 is installed in the required position, and then the vertical plate 5 is lifted to the top of the matching lock plate A2, and the limit column A7 is aligned with the matching lock hole A3, and then the vertical plate 5 is lowered, so that the lower limit column A7 is stuck in the matching lock hole A3, forming the initial assembly of the support column 1 and the cross plate 6, and then another support column 1 is lifted to the top of the upper cross plate 6 by a crane, and the matching lock hole A3 at the matching lock plate A2 is aligned with the limit column A7 at the upper cross plate 6, and then the support column 1 is lowered, so that the matching lock hole A3 is sleeved on the outside of the limit column A7, so that the initial splicing between the two adjacent support columns 1 can be achieved with the help of the limit column A7;

[0071] The second step is to lift the crossbeam body 9 to a height suitable for the vertical plate 5 by using a lifting device, and then put the lock hole B11 on the limit column B8 to form the initial loading of the crossbeam body 9;

[0072] More specifically, the crossbeam body 9 is lifted horizontally, and then the locking hole B11 on the crossbeam body 9 is moved into the space between the two cross plates 6, and the locking plate B10 is sleeved on the limit column B8 through the locking hole B11, and the crossbeam body 9 is initially loaded;

[0073] The third step is to rotate the transmission shaft 25 to cause the positioning frame 16 and the limiting frame 17 to flip over and position the support column 1 and the beam body 9;

[0074] In more detail, by rotating the transmission shaft 25 with the help of a tool, the two threaded receiving grooves with opposite thread rotation directions are matched, so that the two threaded rods 26 can move out of the threaded receiving grooves following the rotation of the transmission shaft 25, thereby driving the support ears 27 to move, and since the linkage rod 28 is connected between the support ears 27 and the eccentric plate B20, when the support ears 27 are displaced, the eccentric plate B20 can be pulled by the linkage rod 28, and the eccentric plate A19 can be pulled by the displacement of the linkage column 22 inside the guide groove 21, thereby driving the corresponding two guide shafts 15 to rotate at the same time, so that the positioning frame 16 is in close contact with the corresponding locking plate A2 surface, and the limiting frame 17 is flipped toward the locking plate A2, limiting the stabilizing column 12 in the waist hole 18, thereby forming a locking position of the support column 1 and the beam body 9, which greatly improves the assembly efficiency of the support column 1 and the beam body 9;

[0075] After the transmission shaft 25 rotates, the stabilizing ring 31 is rotated so that the stabilizing ring 31 moves on the threaded section 30 and fits tightly against the gasket, thereby increasing the friction force of the transmission shaft 25 and preventing the transmission shaft 25 from rotating uncontrollably.

[0076] Step 4: Splice the two beam bodies 9 through the lock holes B11, and set a locking assembly 13 at the splicing point, and then splice the two beam bodies 9 through the locking assembly 13;

[0077] More specifically, the locking hole B11 of the other beam body 9 is spliced ​​with the locking hole B11 of the beam body 9 to be spliced ​​by a crane, and then the assembly frame 32 is placed at the splicing position of the two beam bodies 9, and the transmission screw B34 is rotated, and the connection between the transmission screw B34 and the transmission screw A33 is coordinated, so that the transmission screw A33 can rotate with the transmission screw B34, and because the thread rotation direction of the transmission screw B34 is opposite to that of the transmission screw A33, when the transmission screw A33 and the transmission screw B34 rotate, they can drive The two displacement plates 35 are brought close to each other to move the locking rod A36 and the locking plate B37 into the locking hole B11, thereby realizing the splicing between the two beam bodies 9 through the locking rod A36 and the locking plate B37, and cooperating with the connection between the displacement plates 35 and the conductive plate 41. When the displacement plates 35 are brought close to each other, the transmission column 39 can be pulled through the conductive groove 42, so that the transmission column 39 drives the positioning clamp 40 to vertically displace under the limit of the linear guide rail 38 until the positioning clamp 40 contacts the beam body 9 and locks the beam body 9 again.

[0078] In summary, the beam-column structure and construction method for ultra-large span steel structure buildings, through the combined connection of the support column 1, the beam carrying assembly 4 and the beam body 9, can achieve rapid splicing between the support column 1, the beam carrying assembly 4 and the beam body 9 at the construction site with the help of the stabilization assembly, which greatly shortens the construction period and facilitates later recycling.

[0079] The beam-column structure and construction method for ultra-large span steel structure buildings can utilize the structural coordination of the locking assembly 13 to achieve effective locking between adjacent beam bodies 9 by utilizing the relative displacement of the two displacement plates 35, thereby meeting the construction requirements of steel structure buildings under ultra-large spans.
