Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe and steel beam connection, and in particular to a structurally stable steel pipe and steel beam connection structure. Background Art

[0002] Steel structures and steel-concrete composite structures are lightweight, high-strength, ductile, and highly reliable. They offer excellent energy-saving, mechanical, and seismic performance. They also possess strong styling capabilities, a high degree of industrialization, and high economic benefits. They are widely used in multi-story and super-high-rise buildings, industrial buildings, large stadiums, and public infrastructure. Currently, the main connection methods for rectangular steel tubular columns and I-beams include diaphragm joints, beam-end clamping joints, and through-type joints.

[0003] Most steel pipe-steel beam connections are mainly made by welding and high-strength bolting. Various connecting plates are welded on the outer wall of the steel pipe, and then the I-beam is screwed to these connecting plates. The connection strength between the connecting plates and the steel pipe is entirely guaranteed by the welded nodes, which requires welding multiple connecting plates to disperse the force to ensure the connection strength while also ensuring the welding quality. In order to find a more convenient and stable connection structure, designers have designed a connection structure in which slots are opened in the steel pipe and connecting plates are inserted to form a connection structure for the I-beam to connect. However, this structure is currently mainly used for connecting I-beams in both directions on opposite sides, and the installation of the connecting plates is inconvenient. Therefore, when the four sides of the steel pipe need to be connected to I-beams, a new connection structure needs to be redesigned.

[0004] In view of this, a structurally stable steel pipe-steel beam connection structure is designed, which can install I-beams on all four sides of the steel pipe through a penetrating structure. It also has the characteristics of easy installation, reduces dependence on welding reliability, and effectively avoids the stress concentration problem caused by grooving of the steel pipe. Summary of the Invention

[0005] The object of the present invention is to provide a structurally stable steel pipe and steel beam connection structure to solve the problems described in the background art.

[0006] The technical solution of the present invention is achieved as follows:

[0007] The cam is connected to the front of the steel pipe by a plurality of vertical cross-sections, and the cam is connected to the front of the steel pipe by a plurality of vertical cross-sections. The cam is secured to the outside of the tube and is accessible through a latch lock and is secured to the outside of the tube by a latch lock and is accessible through a latch lock.

[0008] A further technical solution is that a plurality of first long holes are opened on the extended connecting plate, a plurality of second long holes are opened on the portion of the first transverse connecting plate extending to the outside of the steel pipe, a plurality of third long holes are opened on the portion of the second transverse connecting plate extending to the outside of the steel pipe, a plurality of fourth long holes are opened on the pad, a plurality of fifth long holes are opened on the portion of the second through-connecting plate extending to the outside of the steel pipe, and through holes matching the first long holes, the second long holes, the third long holes, the fourth long holes and the fifth long holes are opened on the portions where the I-beam is connected to the extended connecting plate, the first transverse connecting plate, the second transverse connecting plate and the second through-connecting plate.

[0009] A further technical solution is that the through hole is an elongated hole.

[0010] A further technical solution is that the length of the first connecting plate is greater than the distance between the left and right outer walls of the steel pipe, and the left and right ends of the corresponding first connecting plate pass out of the left and right side walls of the steel pipe, and the edge of the flange plate of the corresponding I-beam connected to the extended connecting plate is provided with an avoidance groove for avoiding the first connecting plate.

[0011] A further technical solution is that a chamfer is provided at the connection between the first penetration plate and the extended connection plate.

[0012] A further technical solution is that it also includes multiple triangular angle code connectors, which are respectively arranged at the connection between the first transverse plate and the steel pipe, one end of the angle code connector at the connection between the first transverse plate and the steel pipe is bolted to the first transverse plate, and the other end is fitted and abutted against the side wall of the steel pipe; multiple angle code connectors are also respectively arranged at the connection between the second transverse plate and the steel pipe, one end of the angle code connector at the connection between the second transverse plate and the steel pipe is bolted to the second transverse plate, and the other end is fitted and abutted against the side wall of the steel pipe.

[0014] The beneficial effects of the present invention are:

[0015] 1. Penetrating cross structure: The internal cross skeleton is formed by the vertical interlacing of the first connecting plate and the second connecting plate, which cooperates with the steel pipe body to form a multi-dimensional force system, significantly improving the node stiffness and anti-deformation ability.

[0016] 2. Stress dispersion design: The combination of I-shaped groove + vertical groove + horizontal groove is used for opening. The stress concentration problem caused by the opening is effectively avoided through the precise fitting and filling of the through-hole component, the second through-hole plate and the second horizontal plate with the groove.

[0017] 3. Multi-directional connection enhancement: The upper and lower double abutment of the first and second transverse connecting plates, combined with the angle connectors, forms a three-dimensional force transmission path, achieving multi-directional bearing of axial force, bending moment and shear force.

[0018] 4. Long hole tolerance system: 5 types of long holes (first to fifth) are matched with the through holes of the I-beam to form adjustable allowances to achieve rapid hole assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0034] See also Figures 1 to 13A structurally stable steel pipe 1-steel beam connection structure comprises a rectangular steel pipe 1 and an I-beam 2 respectively arranged on the front, back, left and right sides of the steel pipe 1. The left and right side walls of the steel pipe 1 are symmetrically provided with "I"-shaped grooves 7, the front and back side walls of the steel pipe 1 are symmetrically provided with vertical grooves 8, and horizontal grooves 9 are provided above and below the vertical grooves 8. The horizontal grooves 9 are perpendicular to the vertical grooves 8 and are not connected to the vertical grooves 8. The upper horizontal groove 9 is higher than the top of the "I"-shaped groove 7, and the lower horizontal groove 9 is lower than the bottom of the "I"-shaped groove 7.

[0035] The 'I'-shaped groove 7 is penetrated by a connecting component 3, which includes a rectangular first connecting plate 301. The left end of the first connecting plate 301 is provided with an extended connecting plate 303 whose height is less than that of the first connecting plate 301. The right end of the first connecting plate 301 is also provided with an extended connecting plate 303 whose height is less than that of the first connecting plate 301. The top and bottom of the first connecting plate 301 are respectively welded with first cross-connecting plates 305. When the connecting component 3 is slidably inserted into the 'I'-shaped groove 7, the first connecting plate 301 and the first cross-connecting plate 305 are embedded in the 'I'-shaped groove 7, the extended connecting plate 303 is outside the steel pipe 1, and the left and right ends of the first cross-connecting plate 305 extend to the outside of the steel pipe 1.

[0036] The first connecting plate 301 and the first transverse connecting plate 305 are hammered into the I-shaped groove 7. The first connecting plate 301 and the first transverse connecting plate 305 fit into the I-shaped groove 7 to fill the I-shaped groove 7, thereby reducing stress concentration and deformation of the steel pipe 1 caused by the opening of the I-shaped groove 7.

[0037] During conventional construction, due to the cutting error of the I-beam 2, the I-beam 2 needs to be moved a small distance toward or away from the steel beam. At this time, the left and right positions of the connecting component 3 in the steel beam can be adjusted by tapping. After the installation position is determined, the connection between the first connecting plate 301 and the first cross-connecting plate 305 and the "I"-shaped groove 7 can be welded for auxiliary fixation to reduce dependence on welding reliability.

[0038] The front and rear end surfaces of the first connecting plate 301 are also provided with long straight holes 302, and the second connecting plate 6 is passed through the vertical groove 8. The front and rear ends of the second connecting plate 6 extend to the outside of the steel pipe 1 respectively, and the middle part of the second connecting plate 6 is passed through the long straight hole 302. The outer wall of the second connecting plate 6 and the inner wall of the long straight hole 302 slide and fit with each other.

[0039] By providing the vertical groove 8 and the long straight hole 302, the second penetration plate 6 can pass through the front and rear ends of the steel pipe 1. The embedded cooperation of the second penetration plate 6 and the vertical groove 8 can fill the vertical groove 8, thereby reducing the stress concentration deformation of the steel pipe 1 caused by the opening of the vertical groove 8. At the same time, the cooperation of the second penetration plate 6 and the long straight hole 302 can fill the long straight hole 302. The mutual penetration and vertical connection between the first penetration plate 301 and the second penetration plate 6 increases the overall structural strength of the penetration component 3 and the second penetration plate 6, and increases the stability of the connection structure.

[0040] At the same time, the cross internal structure formed by the steel pipe 1, the connecting assembly 3 and the second connecting plate 6 increases the structural strength of the steel pipe 1 at that location.

[0041] During installation, the second connection plate 6 is knocked into the vertical groove 8 and the long straight hole 302 by knocking. Due to the cutting error of the I-beam 2, the I-beam 2 needs to be moved a small distance toward or away from the steel beam. At this time, the front and rear positions of the second connection plate 6 in the steel beam can be adjusted by knocking. After determining the installation position, the connection between the second connection plate 6 and the vertical groove 8 is welded for auxiliary fixation to reduce dependence on welding reliability.

[0042] A second transverse connecting plate 304 is passed through the horizontal and vertical grooves 9. The front and rear ends of the second transverse connecting plate 304 extend to the outside of the steel pipe 1 and a detachable pad 5 is provided at the end facing the vertical groove 8. The first transverse connecting plate 305 and the second transverse connecting plate 304 above the first connecting plate 301 fit together and abut against each other, and the first transverse connecting plate 305 and the second transverse connecting plate 304 below the first connecting plate 301 fit together and abut against each other.

[0043] During installation, after the front-to-back I-beam 2 is secured by the second through-plate 6, the second cross-plate 304 is hammered into the horizontal and vertical grooves 9, and the backing plate 5 is then hammered into the gap between the second cross-plate 304 and the flange of the I-beam 2. Once the second cross-plate 304 is in place, the abutment between the second cross-plate 304 and the first cross-plate 305 increases the structural strength of the entire connection.

[0044] By providing the first transverse connecting plate 305 and the second transverse connecting plate 304 , the flange plate of the I-beam 2 is also connected to the steel beam, thereby increasing the structural strength of the entire connection structure.

[0045] The I-beam 2 includes a web and flange plates at both ends of the web. The web of the I-beam 2 arranged on the left and right sides of the steel pipe 1 is bolted to the extended connecting plate 303 and the flange plates are bolted to the first transverse connecting plate 305. The web of the I-beam 2 arranged on the front and rear sides of the steel pipe 1 is bolted to the second through-connecting plate 6 and the flange plates are bolted to the second transverse connecting plate 304 and the pad 5.

[0046] Specifically, a plurality of first elongated holes 304 are provided on the extended connecting plate 303, a plurality of second elongated holes 306 are provided on the portion of the first transverse connecting plate 305 extending to the outside of the steel pipe 1, a plurality of third elongated holes 401 are provided on the portion of the second transverse connecting plate 304 extending to the outside of the steel pipe 1, a plurality of fourth elongated holes 501 are provided on the pad 5, a plurality of fifth elongated holes 601 are provided on the portion of the second connecting plate 6 extending to the outside of the steel pipe 1, and through holes matching the first elongated holes 304, the second elongated holes 306, the third elongated holes 401, the fourth elongated holes 501 and the fifth elongated holes 601 are provided at the portions where the I-beam 2 is connected to the corresponding connecting plate 303, the first transverse connecting plate 305, the second transverse connecting plate 304 and the second connecting plate 6.

[0047] By providing the first elongated hole 304 , the second elongated hole 306 , the third elongated hole 401 , the fourth elongated hole 501 and the fifth elongated hole 601 , slight adjustment of the connection when the I-beam 2 moves due to cutting errors is facilitated, thereby increasing the convenience of connection.

[0048] Specifically, the through hole is a long hole. The through hole on the I-beam 2 is a long hole, which also facilitates improving the connection convenience.

[0050] When using this solution, by setting the length of the first connecting plate 301 to be greater than the distance between the left and right outer walls of the steel pipe 1, the first connecting plate 301 can always fill the "I"-shaped groove 7 during movement and adjustment. The flange edge of the I-beam 2 connected to the extended connecting plate 303 is provided with a clearance groove 10 to avoid the first connecting plate 301, ensuring that the I-beam 2 and the steel pipe 1 are in the best possible fit.

[0051] Preferably, a chamfer is provided at the connection between the first penetration plate 301 and the extended connection plate 303 to reduce stress concentration between the first penetration plate 301 and the extended connection plate 303 .

[0053] When the above solution is used, by providing the triangular angle connector 11, the force transmission of the I-beam 2 can be dispersed, thereby increasing the overall strength of the connection structure.

[0054] Preferably, the plurality of angle code connectors 11 are respectively arranged at the connection between the I-beam 2 and the steel pipe 1, and one end of the angle code connector 11 at the connection between the I-beam 2 and the steel pipe 1 is screwed to the I-beam 2, and the other end is fitted and abutted against the side wall of the steel beam.
