DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0043] Embodiment 1:

[0044] See also Figure 1-11 , a beam-column structure for a super-long-span steel structure building, comprising:

[0045] A support column 1, the top and bottom ends of the support column 1 are fixedly connected with a locking plate A2, and both ends of the locking plate A2 are provided with locking holes A3;

[0046] The crossbeam mounting assembly 4 is arranged between the two supporting columns 1. The crossbeam mounting assembly 4 includes a vertical plate 5 and two horizontal plates 6. The two horizontal plates 6 are respectively fixedly connected to the top and bottom ends of the vertical plate 5. The ends of the two horizontal plates 6 that are away from each other are fixedly connected with limit columns A7 adapted to the matching lock holes A3. The two sides of the vertical plate 5 are fixedly connected with limit columns B8. A stabilization assembly is also arranged between the two horizontal plates 6.

[0047] The crossbeam body 9, both ends of the crossbeam body 9 are fixedly connected with a locking plate B10, the locking plate B10 is provided with a locking hole B11 at a position adapted to the limit column B8, the top and bottom ends of the crossbeam body 9 are fixedly connected with two stabilizing columns 12, and the stabilizing assembly is used to position the support column 1 and the crossbeam body 9;

[0048] A locking assembly 13, which is assembled at the connection of the two crossbeam bodies 9 and is used to splice the two crossbeam bodies 9;

[0049] In this embodiment, the support column 1 and the crossbeam body 9 are both I-beams, and their characteristics are as follows:

[0050] 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.

[0051] Good stability: I-beams have good lateral stability and rigidity, and can effectively resist additional internal forces caused by external wind or vibration.

[0052] Combinability: I-beams can be flexibly combined with other types of steel structural components such as (H-shaped steel, angle steel, channel steel) to form a complex structural system, making I-beams highly flexible and adaptable in actual engineering applications.

[0053] Facilitate industrialized production: Rapid and efficient production is achieved through automated production lines, which greatly reduces construction costs and improves construction efficiency.

[0054] 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 with the positioning ear 14, the middle part of the positioning ear 14 is rotatably connected with the guide shaft 15, each guide shaft 15 is fixedly connected with 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 with the eccentric plate A19 and the eccentric plate B20, a guiding groove 21 is opened in the middle of the eccentric plate A19, and the end of the eccentric plate B20 away from the guiding shaft 15 is fixedly connected with a linkage column 22, and the linkage column 22 is also movably connected inside the guiding groove 21;

[0055] 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:

[0056] Single tooth pattern: composed of a single protrusion arranged in a tooth shape.

[0057] 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.

[0058] Grid pattern: 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.

[0059] Petal-shaped pattern: It is composed of multiple inward-bending petal-shaped protrusions. This pattern can not only ensure a certain anti-slip effect, but also has a certain decorative effect.

[0060] Spiral pattern: arranged in a spiral form, the distance and height between each spiral are specially designed, which can significantly improve the anti-slip effect of the positioning frame 16 and the limiting frame 17;

[0061] Both ends of the vertical plate 5 are fixedly connected with a positioning seat 24, and the middle of the positioning seat 24 is rotatably connected with 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 in opposite directions. The insides of the two threaded receiving grooves are threadedly connected with a threaded rod 26, and one end of the threaded receiving groove located outside the threaded rod 26 is fixedly connected with a support ear 27, and one end of the support ear 27 is rotatably connected with 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;

[0062] In this embodiment, the transmission shaft 25 is rotated with the aid of a tool, and the two thread 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 thread receiving grooves, thereby driving the displacement of the support ear 27. Since the linkage rod 28 is connected between the support ear 27 and the eccentric plate B20, when the support ear 27 is 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 simultaneously.

[0063] Furthermore, the middle part of one side of the eccentric plate B20 is rotatably connected with a rotating shaft 23, and one end of the linkage rod 28 away from the supporting 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 the smoothness of the linkage of the linkage rod 28 between the supporting ear 27 and the eccentric plate B20.

[0064] Furthermore, the top of the support ear 27 is fixedly connected to a limit rod 29, and the end of the limit rod 29 close to the vertical plate 5 is also slidably connected to the vertical plate 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 vertical plate 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 vertical plate 5.

[0065] Furthermore, a threaded section 30 is provided at one end of the transmission shaft 25, and the outer side of the stabilizing ring 31 is threadedly connected with the stabilizing ring 31, and a gasket is fixedly connected to one 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 is rotated, the stabilizing ring 31 is rotated again, so that the stabilizing ring 31 moves at the threaded section 30 and fits tightly with the gasket, thereby increasing the friction force of the rotation of the transmission shaft 25;

[0066] 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 respectively. 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 directions 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, and the sides of the two displacement plates 35 close to each other are fixedly connected to the locking rod A36. 36 and a locking plate B37, and the locking rod A36 and the locking plate B37 are both connected by clamping with the matching lock hole B11, the top and bottom ends of the assembly frame 32 are fixedly connected with linear guide rails 38, each linear guide rail 38 is slidably connected with a transmission column 39, and the end of the transmission column 39 away from the linear guide rail 38 is fixedly connected with a positioning clamping plate 40, the top and bottom of the two displacement plates 35 are both obliquely fixedly connected with a conductive plate 41, the middle of the four conductive plates 41 are 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 respectively;

[0067] 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 beam bodies 9 through the locking rod A36 and the locking plate B37, and in coordination 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 through groove 42, so that the transmission column 39 drives the positioning clamping plate 40 to vertically displace under the limit of the linear guide 38, until the positioning clamping plate 40 contacts with the beam body 9, and the beam body 9 is locked again;

[0068] In detail, the cross-sectional shape of the linear guide 38 is an I-shaped one, and a linear slider is fixedly connected to one end of the transmission column 39 connected to the linear guide 38. An I-shaped linear slide groove is provided in the middle of the linear slider. The linear slider is slidably connected to the linear guide 38 through the linear slide groove. By using the arrangement of the linear slider, the displacement of the transmission column 39 can be effectively guided, thereby ensuring the contact effect between the positioning clamping plate 40 and the crossbeam body 9.

[0069] Furthermore, one end of the locking rod A36 is fixedly connected to a clamping rod, one end of the locking plate B37 is provided with a clamping slot, and the locking rod A36 is connected to the inside of the clamping slot through the clamping rod. By utilizing the settings of the clamping rod and the clamping slot, when the locking rod A36 and the locking plate B37 move into the locking hole B11, the clamping rod will simultaneously move into the clamping slot, thereby enhancing the connection stability between the cross plate 6 and the locking plate B37.

[0070] Embodiment 2:

[0071] 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:

[0072] The first step is to lift the beam carrying assembly 4 to the top of the support column 1 by means of a lifting device, and make the limit column A7 correspond to the locking hole A3, and then move the limit column A7 into the locking hole A3;

[0073] 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 then the prefabricated support column 1 and the cross beam body 9 are transported to the construction site, and then the support column 1 is vertically lifted 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 locking plate A2, and the limit column A7 is made to correspond to the locking hole A3, and then the vertical plate 5 is lowered, so that the lower limit column A7 is inserted into the locking 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 locking hole A3 at the locking plate A2 is made to correspond to the limit column A7 at the upper cross plate 6, and then the support column 1 is lowered, so that the locking hole A3 is sleeved on the outside of the limit column A7, so that the initial splicing between two adjacent support columns 1 can be achieved with the help of the limit column A7;

[0074] The second step is to lift the cross beam body 9 to a height suitable for the vertical plate 5 by means of a lifting device, and then put the lock hole B11 on the limit column B8 to form the initial loading of the cross beam body 9;

[0075] More specifically, the cross beam body 9 is hoisted horizontally, and then the locking hole B11 at the cross beam 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 by means of the locking hole B11, and the cross beam body 9 is initially loaded;

[0076] 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 crossbeam body 9;

[0077] In more detail, by rotating the transmission shaft 25 with the aid of a tool, in conjunction with the setting of the threaded receiving grooves with opposite thread rotation directions at two places, 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, and 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 at the same time, so that the positioning frame 16 is in close contact with the corresponding surface of the locking plate A2, and the limiting frame 17 is flipped toward the locking plate A2, and the stabilizing column 12 is limited in the waist hole 18, thereby forming a locking 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;

[0078] 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.

[0079] Step 4: Splice the two crossbeam bodies 9 through the locking holes B11, and set a locking assembly 13 at the splicing position, and then splice the two crossbeam bodies 9 through the locking assembly 13;

[0080] More specifically, the locking hole B11 of the other beam body 9 is assembled with the locking hole B11 of the beam body 9 to be assembled by a crane, and then the assembly frame 32 is placed at the joint 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 directions of the transmission screw B34 and the transmission screw A33 are opposite, 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, so as to realize the splicing between the two beam 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 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 plate 40 to vertically displace under the limit of the linear guide rail 38 until the positioning clamp plate 40 contacts the beam body 9, and the beam body 9 is locked again.

[0081] 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 mounting assembly 4 and the beam body 9, can achieve rapid splicing between the support column 1, the beam mounting assembly 4 and the beam body 9 at the construction site with the help of stabilization components, which greatly shortens the construction period and facilitates later recycling.

[0082] 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 two displacement plates 35, thereby meeting the construction requirements of ultra-large span steel structure buildings.
