Abstract
Description
Technical Field
[0001] This invention relates to the field of building steel structure connection technology, and in particular to a connection structure between H-beams and square steel tube columns. Background Technology
[0002] In steel structure buildings, square steel tube columns and H-beams are widely used, especially in high-rise steel structure buildings. Compared with conventional concrete columns, the use of square steel tube columns and H-beams can reduce the column cross-section and increase the actual usable area.
[0003] Currently, when connecting square steel pipe columns to H-beams, connecting components such as angle steel and bolts are required. Specifically, several bolt holes are made on both the side walls of the square steel pipe column and the H-beam for bolts to pass through. Then, the angle steel is attached to the side walls of both the square steel pipe column and the H-beam, and finally, bolts are used to lock them in place. However, after connecting the H-beam to the side wall of the square steel pipe column, only one side wall of the square steel pipe column bears the force, resulting in a small force-bearing area. This reduces the overturning resistance of the H-beam. Furthermore, making too many bolt holes on the side wall of the square steel pipe column can also affect the local strength of the square steel pipe column, making it prone to local tearing, which in turn affects the safety of the entire building structure. Summary of the Invention
[0004] The purpose of this invention is to provide a connection structure between H-beams and square steel tube columns to solve the technical problems existing in the prior art.
[0005] To solve the above-mentioned technical problems, the present invention provides a connection structure between an H-beam and a square steel column, comprising a square steel column, an H-beam, an inner connection component, an outer connection component, and a drive component. The square steel tube column has through holes on its sidewalls for the internal connecting components to pass through. The external connection assembly is fixedly installed on the side wall of the H-beam. One end of the drive component is connected to the external connection component, and the other end is connected to the internal connection component. When the inner connecting component enters the square steel column through the through hole, the driving component drives the inner connecting component to move inside the square steel column, so that the inner connecting component acts on the inner wall of the square steel column.
[0006] As a further improvement of the present invention: the external connection assembly includes a U-shaped plate and a bolt and nut assembly. The U-shaped plate is provided in two sets, and the two sets of U-shaped plates are respectively embedded on opposite sides of the H-beam. The bolt and nut assembly is used to connect the H-beam and the two sets of U-shaped plates into one unit.
[0007] As a further improvement of the present invention: several ribs are fixedly provided on the inner side of both sets of U-shaped plates.
[0008] As a further improvement of the present invention: the driving component includes a support tube and a rotating shaft. The support tube extends transversely through several ribs and is fixedly connected to the ribs. A sliding groove is formed along the length of the sidewall of the support tube. One end of the rotating shaft extends to the outside of the support tube, and the other end extends to the inside of the support tube and rotatably engages with the support tube. Two sets of external threads are formed on the shaft inside the support tube, with the two sets of external threads rotating in opposite directions. The internal connection assembly includes an outer ring block, an inner support rod, an elastic element, an inner ring block, and a connecting rod. Two sets of outer ring blocks and two sets of inner ring blocks are provided, each corresponding to one of the inner ring blocks. The two sets of outer ring blocks are fitted around the outside of the support tube, and the two sets of inner ring blocks are fitted around the outside of the rotating shaft and threaded with the two sets of external threads. A connecting rod is fixedly installed on the outer wall of each set of inner ring blocks. The end of the connecting rod away from the corresponding inner ring block extends from the sliding groove to the outside of the support tube and is fixedly connected to the outer ring block. Each of the two sets of outer ring blocks has a plurality of inner support rods rotatably disposed on one of their opposite ends. Each set of inner support rods is connected to the corresponding outer ring block by an elastic element, which provides elastic tension to the inner support rods.
[0009] As a further improvement of the present invention: each of the two sets of outer ring blocks has a plurality of second slots at its mutually distant edges, and one end of each of the plurality of inner support rods extends into the interior of the plurality of second slots and is rotatably connected to the inner wall of the second slot by a pin. Both sets of outer ring blocks have several first slots on their circumferential sidewalls. The first slots are connected to the second slots. A vertical stepped surface is formed between the first slots and the corresponding second slots. One end of the elastic element is connected to the inner wall of the first slot, and the other end is connected to the inner support rod.
[0010] As a further improvement of the present invention: the elastic element is a spring or a metal sheet.
[0011] As a further improvement of the present invention: a sealing block adapted to the through hole is also fixedly provided on the outer wall of the support tube.
[0012] By adopting the above technical solution, the present invention has the following beneficial effects: In this embodiment of the invention, when connecting the H-beam to the side wall of the square steel column, the inner connecting component can be inserted into the square steel column through the through hole. Then, the H-beam is placed on the outside of the square steel column, with the end of the H-beam in contact with the outer wall of the square steel column. Subsequently, the outer connecting component is fixedly installed on the side wall of the H-beam. Then, the driving component is used to drive the inner connecting component to move inside the square steel column, so that the inner connecting component acts on the inner wall of the square steel column. At this time, the inner connecting component provides support for the H-beam from inside the square steel column, and the outer connecting component provides support for the H-beam from outside the square steel column, thereby completing the connection between the H-beam and the square steel column. Compared with the prior art, through the cooperation of the inner and outer connecting components, it is not necessary to open too many bolt holes on the side wall of the square steel column, which can increase the connection area between the H-beam and the square steel column, thereby improving the connection strength between the H-beam and the square steel column, improving the stability of the H-beam and the safety of the square steel column.

[0018] The present invention will be further explained below with reference to specific embodiments.
[0019] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a connection structure between an H-beam and a square steel column, including a square steel column 10, an H-beam 20, an inner connecting component 30, an outer connecting component 40, and a driving component 50. A through hole 101 is provided on the side wall of the square steel column 10, through which the inner connecting component 30 can pass. The outer connecting component 40 is fixedly installed on the side wall of the H-beam 20. One end of the driving component 50 is connected to the outer connecting component 40, and the other end is connected to the inner connecting component 30. When the inner connecting component 30 enters the square steel column 10 through the through hole 101, the driving component 50 drives the inner connecting component 30 to move inside the square steel column 10, causing the inner connecting component 30 to act on the inner wall of the square steel column 10.
[0020] When connecting the H-beam 20 to the side wall of the square steel column 10, the inner connecting component 30 can be inserted into the square steel column 10 through the through hole 101. Then, the H-beam 20 is placed on the outside of the square steel column 10, with the end of the H-beam 20 contacting the outer wall of the square steel column 10. Subsequently, the outer connecting component 40 is fixedly installed on the side wall of the H-beam 20. Then, the driving component 50 is used to drive the inner connecting component 30 to move inside the square steel column 10, so that the inner connecting component 30 acts on the inner wall of the square steel column 10. At this time, the inner connecting component 30 provides support for the H-beam 20 from inside the square steel column 10, and the outer connecting component 40 provides support for the H-beam 20 from outside the square steel column 10, thereby completing the connection between the H-beam 20 and the square steel column 10. Through this connection method, the connection area between the H-beam 20 and the square steel column 10 can be increased, thereby improving the connection strength between the H-beam 20 and the square steel column 10 and improving the stability of the H-beam 20.
[0021] Please see Figure 1 , Figure 2 as well as Figure 3 In one embodiment, the external connecting component 40 includes a U-shaped plate 401 and a bolt and nut assembly 403. Two sets of U-shaped plates 401 are respectively embedded on opposite sides of the H-beam 20. The bolt and nut assembly 403 connects the H-beam 20 and the two sets of U-shaped plates 401 into a single unit. Specifically, bolt holes are provided on the web of the H-beam 20 and on the plates of the two sets of U-shaped plates 401, allowing bolts from the bolt and nut assembly 403 to pass through. After the two sets of U-shaped plates 401 are respectively embedded on opposite sides of the H-beam 20, the bolt holes on the two sets of U-shaped plates 401 are aligned with the bolt holes on the web of the H-beam 20. Then, the bolts included in the bolt and nut assembly 403 are passed through the aligned bolt holes, and then locked using the nuts included in the bolt and nut assembly 403, thereby connecting the two sets of U-shaped plates 401 and the H-beam 20 into a single unit.
[0022] Please see Figure 1 , Figure 2 as well as Figure 3 In one embodiment, a plurality of ribs 402 are fixedly provided on the inner side of both sets of U-shaped plates 401.
[0023] The rib plate 402 provides support for the U-shaped plate 401, thereby enhancing the rigidity of the U-shaped plate 401 and improving the external connection effect of the H-beam 20.
[0024] Please see Figure 4 as well as Figure 5In one embodiment, the drive assembly 50 includes a support tube 501 and a rotating shaft 503. The support tube 501 extends laterally through several ribs 402 and is fixedly connected to the ribs 402. A groove 502 is formed along the length of the sidewall of the support tube 501. One end of the rotating shaft 503 extends to the outside of the support tube 501, and the other end extends to the inside of the support tube 501 and rotatably engages with the support tube 501. Two sets of external threads 504 are formed on the shaft of the rotating shaft 503 located inside the support tube 501, with opposite rotation directions. The inner connection assembly 30 includes an outer ring block 301, an inner support rod 303, an elastic element 305, an inner ring block 306, and a connecting rod 307. Two sets of outer ring blocks 301 and two sets of inner ring blocks 306 are provided in each pair. The outer ring block 301 is sleeved on the outside of the support tube 501, and the two sets of inner ring blocks 306 are circumferentially arranged inside the support tube 501. The two sets of inner ring blocks 306 are sleeved on the outside of the rotating shaft 503 and threadedly engaged with the two sets of external threads 504. The connecting rod 307 is fixedly arranged on the outer wall of each of the two sets of inner ring blocks 306. The end of the connecting rod 307 away from the corresponding inner ring block 306 extends from the sliding groove 502 to the outside of the support tube 501 and is fixedly connected to the outer ring block 301. Several inner support rods 303 are rotatably arranged on the edges of the two sets of outer ring blocks 301 that are far apart from each other. Each set of inner support rods 303 is connected to the corresponding outer ring block 301 through the elastic element 305. The elastic element 305 is used to provide elastic tension to the inner support rod 303.
[0025] After the bolt and nut assembly 403 fixes the two sets of U-shaped plates 401 to the opposite sides of the H-beam 20, the workers use hoisting machinery to lift the H-beam 20 to one side of the square steel column 10 and drive the H-beam 20 close to the side wall of the square steel column 10. The rib plate 402 drives the support pipe 501 to move closer to the side wall of the square steel column 10. At this time, the workers can press down on several inner support rods 303 on the two sets of outer ring blocks 301 to keep the inner support rods 303 in a horizontal state. When one end of the support pipe 501 extends into the square steel through the through hole 101... When the tube column 10 is inside, the two sets of outer ring blocks 301 and several inner support rods 303 enter the square steel tube column 10 together with the support pipe 501. After the inner support rods 303 enter the square steel tube column 10, several elastic elements 305 pull the inner support rods 303, causing the inner support rods 303 to rotate to a vertical state. Then, as the H-beam 20 continues to approach the square steel tube column 10, after the end of the H-beam 20 contacts the outer wall of the square steel tube column 10, the operator rotates the shaft 503. When the shaft 503 rotates, it passes through two sets of external threads 5 04 The threads of the two sets of inner ring blocks 306 engage with each other, causing the two sets of inner ring blocks 306 to move away from each other along the inside of the support tube 501. When the two sets of inner ring blocks 306 move away from each other, they drive the two sets of outer ring blocks 301 to move away from each other through the connecting rod 307. The connecting rod 307 slides adaptively inside the slide groove 502. The two sets of outer ring blocks 301 drive their respective internal support rods 303 to move away from each other. When the two sets of outer ring blocks 301 act on two opposite side walls inside the square steel tube column 10, the two sets of outer ring blocks 301 can be vertical. Several internal support rods 303 press against two opposite side walls inside the square steel column 10. At this time, the internal support rods 303 can provide support for the support tube 501 from inside the square steel column 10. This support effect is transmitted to the H-beam 20 through the rib plate 402, thereby dispersing the force applied by the H-beam 20 to the square steel column 10 to the two side walls of the square steel column 10, so as to increase the connection area between the H-beam 20 and the square steel column 10, improve the overturning resistance of the H-beam 20, and thus improve the connection strength of the H-beam 20.
[0026] Please see Figure 4 In one embodiment, each of the two sets of outer ring blocks 301 has a plurality of second slots 304 at one of their mutually distant edges. One end of each of the plurality of inner support rods 303 extends into the interior of the plurality of second slots 304 and is rotatably connected to the inner wall of the second slot 304 via a pin (not shown in the figure). Each of the two sets of outer ring blocks 301 has a plurality of first slots 302 on its circumferential sidewall. The plurality of first slots 302 are connected to the plurality of second slots 304. A vertical stepped surface (not shown in the figure) is formed between the first slot 302 and the corresponding second slot 304. One end of the elastic member 305 is connected to the inner wall of the first slot 302, and the other end is connected to the inner support rod 303.
[0027] When the workers press down on the inner support rods 303 to keep them horizontal, the elastic element 305 is stretched. After the inner support rods 303, along with the inner ring block 301 and the support tube 501, enter the square steel column 10 through the through hole 101, the inner support rods 303 are no longer under pressure. Therefore, the elastic element 305 can pull the inner support rods 303, causing them to rotate relative to the pin. When the inner support rods 303 rotate to a vertical position, one side of the inner support rods 303 acts on the vertical stepped surface, thus stably maintaining the vertical position. When the rotating shaft 503 is subsequently rotated, causing the two sets of outer ring blocks 301 to move away from each other, the inner support rods 303 at the ends of the two sets of outer ring blocks 301 that are moving away from each other... 3. The vertical force is applied synchronously to the two opposite side walls inside the square steel tube column 10 to provide support for the support tube 501 from inside the square steel tube column 10. The support effect is transmitted to the rib plate 402 through the support tube 501, and then to the H-beam 20 through the U-shaped plate 401. This disperses the connection force applied by the H-beam 20 to one side wall of the square steel tube column 10 to both side walls of the square steel tube column 10, thereby improving the overturning resistance of the H-beam 20 and thus improving the connection strength between the H-beam 20 and the square steel tube column 10. The above-mentioned arrangement of the elastic element 305 inside the first slot 302 can prevent the elastic element 305 from protruding outward and thus affecting the smooth passage of the outer ring block 301 through the through hole 101.
[0028] In one embodiment, the elastic element 305 may be a spring or a metal sheet, and there is no limitation on this.
[0029] In one embodiment, a sealing block (not shown in the figure) adapted to the through hole 101 is also fixedly provided on the outer wall of the support tube 501.
[0030] After the two sets of outer ring blocks 301 are brought into the square steel column 10 through the through hole 101 at one end of the support tube 501, the sealing block can then be embedded into the through hole 101 to seal the through hole 101, so as to prevent external dust and rainwater from entering the square steel column 10 through the gap between the through hole 101 and the support tube 501, and prevent corrosion damage to the various structures of the internal connection component 30.
[0031] In this embodiment of the invention, when connecting the H-beam 20 to the side wall of the square steel column 10, the inner connecting component 30 can be inserted into the square steel column 10 through the through hole 101. Then, the H-beam 20 is placed on the outside of the square steel column 10, with the end of the H-beam 20 contacting the outer wall of the square steel column 10. Subsequently, the outer connecting component 40 is fixedly installed on the side wall of the H-beam 20. Then, the driving component 50 is used to drive the inner connecting component 30 to move inside the square steel column 10, so that the inner connecting component 30 acts on the inner wall of the square steel column 10. At this time, the inner connecting component 30 moves from the square steel column 10... The internal component 30 provides support for the H-beam 20, while the external connecting component 40 provides support for the H-beam 20 from the outside of the square steel column 10, thus completing the connection between the H-beam 20 and the square steel column 10. Compared with the prior art, through the cooperation of the internal connecting component 30 and the external connecting component 40, it is not necessary to open too many bolt holes on the side wall of the square steel column 10, which can increase the connection area between the H-beam 20 and the square steel column 10, thereby improving the connection strength between the H-beam 20 and the square steel column 10, and improving the stability of the H-beam 20 and the safety of the square steel column 10.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
