Description

Technical Field

[0001] This invention relates to load-bearing components of buildings, and more particularly to a lateral connection device for steel structure columns. Background Technology

[0002] In the process of constructing the main steel structure, it is usually necessary to use a crossbeam (which may be a secondary load-bearing beam or a non-load-bearing beam) to connect two columns laterally. In the existing technology, a basically rigid crossbeam is usually used to connect the two columns. Specifically, the two ends of the crossbeam are configured with mating surfaces, and the surface of each column is machined with an mounting surface. First, the mating surface of the first end of the crossbeam is mated with the mounting surface of the first column, and the first end of the crossbeam is fixed to the first column by fasteners. Then, the mating surface of the second end of the crossbeam is mated with the mounting surface of the second column, and the second end of the crossbeam is fixed to the second column by fasteners.

[0003] The aforementioned connection structure between the beam and the column has the following defects during installation and subsequent use:

[0004] Because errors in the perpendicularity of the beam and column are unavoidable, during the fixing of the second end of the beam to the second column, the initial mating surface of the second end and the mounting surface of the second column are not parallel. This necessitates increasing the tension of the bolts in the corresponding area to correct the non-parallelism as much as possible, ensuring full contact between the mating and mounting surfaces. However, this leads to harmful internal stress between the column and beam, and the bolts in the corresponding area are prone to breakage due to excessive tension. These harmful consequences are especially likely to occur when the steel structure vibrates. Therefore, the aforementioned beam-column connection structure has poor seismic resistance.

[0005] To address the aforementioned problems, existing technology divides the crossbeam into two sections near the column, connecting them with circumferentially arranged columnar springs. These springs allow for compliant adjustment of the mating surfaces at the ends of the crossbeams, preventing excessive tension on the bolts. However, due to the poor shear resistance of the columnar springs, the relative torsion and bending between the two crossbeam sections cannot be effectively suppressed, resulting in insufficient torsional and bending stiffness of the crossbeam, and consequently, insufficient support stiffness and strength. Summary of the Invention

[0006] To address the aforementioned technical problems in the prior art, embodiments of the present invention provide a lateral connection device for steel structure columns.

[0007] To solve the above-mentioned technical problems, the technical solution adopted in the embodiments of the present invention is as follows:

[0009] The column has an installation surface machined on its outer surface;

[0010] The crossbeam includes a main section and a connecting section; the connecting section has a connecting surface at its end away from the main section, the connecting surface being used to mate with the mounting surface and be fixed by bolts; wherein:

[0011] A first docking plate is provided at the end of the main body segment opposite to the docking segment, and a second docking plate is provided at the end of the docking segment opposite to the main body segment;

[0014] Preferably, the connecting disc includes a disc-shaped body, and the first connecting region and the second connecting region are located at the edge of the disc-shaped body.

[0015] Preferably, the connecting disc includes a disc-shaped body, with a plurality of radially arranged protrusions configured by removing material from the edge of the disc-shaped body, the radial protrusions alternately serving as the first connecting region and the second connecting region.

[0016] Preferably, the connecting disc includes a disc-shaped body with a plurality of axial protrusions formed by bending on the disc-shaped body. The plurality of axial protrusions are arranged circumferentially at intervals, and the directions of two adjacent axial protrusions are opposite. The axial protrusions facing the first docking disc serve as the first connecting area, and the axial protrusions facing the second docking disc serve as the second connecting area.

[0017] Preferably, the axial protrusion extends radially along the disc-shaped body; the axial protrusion is formed by stamping in the axial direction using a stamping die.

[0018] Preferably, a first protrusion is configured at the position corresponding to the first connecting area of ​​the first docking plate, and the first protrusion is combined with the first connecting area. A second protrusion is configured at the position corresponding to the second connecting area of ​​the second docking plate, and the second protrusion is combined with the second connecting area, so that the disc-shaped body has a predetermined gap with both the first docking plate and the second docking plate.

[0019] Preferably, the first connecting area and the first mating plate are fixed together by bolts passing through both, and the second connecting area and the second mating plate are fixed together by bolts passing through both.

[0020] Preferably, a central hole is machined in the middle of the connecting plate; a connecting cylinder is provided between the first connecting plate and the second connecting plate, and the middle part of the cylinder wall of the connecting cylinder is bent radially inward; both ends of the connecting cylinder have radially outward-flared outer edges, and the outer edges of both ends of the connecting cylinder are fixed to the first mating plate and the second mating plate by bolts.

[0021] Preferably, a rectangular docking plate is provided at the end of the docking segment away from the main body segment, and the docking surface is formed on the outer surface of the rectangular docking plate.

[0022] Preferably, the outer surface of the column is machined with a vertically extending positioning groove, and the bottom of the positioning groove serves as the mounting surface.

[0023] Compared with the prior art, the beneficial effects of the transverse connection device for steel structure columns disclosed in this invention are:

[0024] The beam connection device provided by this invention reduces the internal stress between the beam and the column, and lowers the tensile force of the bolts in the corresponding area. Therefore, when the main steel structure vibrates, the bolts in the corresponding areas at the mating surface and the mounting surface are less likely to break. In addition, during vibration, the connection structure of the two mating discs and the connecting disc provides a certain degree of seismic resistance between the mating section and the main body section. Importantly, because the structure of the connecting disc is basically a disc-shaped structure, the connection structure of the two mating discs and the connecting disc has a shear resistance stronger than that of a spring. Therefore, it can sufficiently suppress the torsion and bending of the beam to avoid excessive bending and torsion during seismic resistance.

[0037] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0038] An embodiment of the present invention discloses a lateral connection device for steel structure columns, which is used to connect a beam 100 between two columns 200. This device is particularly suitable for the lateral connection of non-load-bearing beams 100. Figures 1 to 6 As shown, the device includes: a column 200 and a crossbeam 100.

[0039] The column 200 is a square tubular column 200 with four flat surfaces. Vertically extending positioning grooves 202 are machined on the opposing surfaces of two columns 200. The bottom of the positioning grooves 202 is machined into mounting surfaces 201.

[0040] The crossbeam 100 includes a main body section 10 and connecting sections 20 located on both sides of the main body section 10 (only one side of the connecting section 20 of the main body section 10 is shown in the attached figure). The main body of the main body section 10 is an I-shaped steel profile, and the main body of the connecting section 20 is also an I-shaped steel profile. The end of the main body section 10 is fixed with a first connecting plate 11 by welding. The end of the connecting section 20 opposite to the main body section 10 is fixed with a second connecting plate 21 by welding. The end of the connecting section 20 away from the main body section 10 is fixed with a rectangular connecting plate 22 by welding. The outer plate surface of the rectangular connecting plate 22 is machined with a connecting surface 221, so that the rectangular connecting plate 22 is embedded in the positioning groove 202 to make the connecting surface 221 fit with the mounting surface 201 of the bottom of the positioning groove 202. The rectangular connecting plate 22 is inserted through bolts and screwed into the column 200 so that the rectangular connecting plate 22 and the column 200 are connected and fixed.

[0041] In this invention, a connecting plate 30 is provided between the first docking plate 11 of the main body segment 10 and the second docking plate 21 of the docking segment 20. This docking plate is divided into multiple first connecting areas 321 and multiple second connecting areas 322. The multiple first connecting areas 321 are arranged circumferentially at intervals, and the multiple second connecting areas 322 are arranged circumferentially at intervals, alternating in the circumferential direction. Multiple bolts are arranged circumferentially on the first docking plate 11, and these bolts are screwed into the first connecting areas 321 respectively, thereby connecting the connecting plate 30 to the first docking plate 11 through the circumferentially arranged first connecting areas 321. Similarly, multiple bolts are arranged circumferentially on the second docking plate 21, and these bolts are screwed into the second connecting areas 322 respectively, thereby connecting the connecting plate 30 to the second docking plate 21 through the circumferentially arranged second connecting areas 322. Thus, the first docking plate 11 and the second docking plate 21 are connected through the connecting plate 30. Since the adjacent first connecting region 321 and second connecting region 322 are respectively connected to the first docking plate 11 and the second docking plate 21, the relative posture of the first docking plate 11 and the second docking plate 21 can be changed sequentially through micro-deformation of the area between the first connecting region 321 and the second connecting region 322.

[0042] In the process of connecting the crossbeam 100 to the two columns 200, firstly, the rectangular mating plate 22 of the mating section 20 at the first end of the crossbeam 100 is mated with the mounting surface 201 of the first column 200 and fixed with bolts. Then, the rectangular mating plate 22 of the mating section 20 at the second end of the crossbeam 100 is oriented toward the mounting surface 201 of the second column 200 and fixed with bolts. If the mating surface 221 of the second end of the crossbeam 100 and the mounting surface 201 of the column 200 are not parallel, this state is corrected by tightening the bolts, so that the mating surface 221 is attached to the mounting surface 201 as a whole. When the non-parallel state is corrected by the bolts, since the first mating plate 11 and the second mating plate 21 are connected by the connecting plate 30, the connecting plate 30 undergoes a slight elastic deformation, which allows the mating section 20 to bend compliantly relative to the main body section 10. Thus, the bolts can make the mating surface 221 and the mounting surface 201 attached as a whole without increasing the tensile force too much, thereby reducing the internal stress between the crossbeam 100 and the column 200 and reducing the tensile force of the bolts in the corresponding area. Therefore, when the main steel structure vibrates, the bolts in the corresponding area of ​​the mating surface 221 and the mounting surface 201 are not easy to break. In addition, when vibration occurs, the connection structure of the two mating plates and the connecting plate 30 gives the mating section 20 and the main body section 10 a certain seismic resistance. Importantly, because the structure of the connecting plate 30 is basically a disc-shaped structure, the connection structure between the two mating plates and the connecting plate 30 has a stronger shear resistance than the spring. Therefore, it can effectively suppress the torsion and bending of the beam 100 to avoid excessive bending and torsion during earthquake resistance.

[0043] In addition, the main body section 10 of the crossbeam 100 and the connecting section 20 are connected by a connecting plate, which is simpler to install compared to circumferentially arranging numerous columnar springs.

[0044] This invention provides three types of docking discs.

[0045] The first type of docking plate.

[0046] like Figure 1 and Figure 2As shown, the connecting disc 30 includes a disc-shaped body 31 made of a high-elasticity modulus metal plate, with a first connecting region 321 and a second connecting region 322 located at the edge of the disc-shaped body 31. A first protrusion 111 is machined at a position corresponding to each of the first connecting regions 321 on the first mating disc 11. A corresponding bolt passes through the first protrusion 111 and is screwed into the threaded hole of the first connecting region 321, thus engaging the first protrusion 111 with the surface of the first connecting region 321. A second protrusion 211 is machined at a position corresponding to each of the second connecting regions 322 on the second mating disc 21. A corresponding bolt passes through the second protrusion 211 and is screwed into the threaded hole of the second connecting region 322, thus engaging the second protrusion 211 with the surface of the second connecting region 322. Thus, the first mating disc 11 and the second mating disc 21 are connected to the connecting disc 30 through the protrusions, thereby forming a predetermined gap between themselves and the connecting disc 30. This predetermined gap serves as a reserved gap to allow the mating section 20 to bend relative to the main body section 10.

[0047] The connecting plate 30 of this structure is basically a flat disc structure. Therefore, the connecting plate 30 of this structure gives the crossbeam 100 the following characteristics: the allowable bending and torsional compliance between the butt joint section 20 and the main body section 10 are both small, and the bending and torsional resistance are both strong. The applicable working conditions are: the assembly error between the crossbeam 100 and the column 200 is predicted to be small, and the crossbeam 100 is required to have a large rigidity.

[0048] The second type of docking plate.

[0049] like Figure 3 and Figure 4 As shown, the connecting disc 30 includes a disc-shaped body 31, and a plurality of radially arranged protrusions 34 are configured by removing material from the edge of the disc-shaped body 31. The radially arranged protrusions 34 alternately serve as the first connecting area 321 and the second connecting area 322. The first mating disc 11 and the second mating disc 21 are also machined with first protrusions 111 and second protrusions 211 respectively corresponding to the first connecting area 321 and the second connecting area 322, so as to provide a reserved gap for the bending of the mating section 20 relative to the main body section 10. The bolts pass through the first protrusions 111 and the second protrusions 211 respectively and are screwed into the threaded holes of the radially arranged protrusions 34.

[0050] The connecting plate 30 of this structure has a radial protrusion 34. Therefore, the connecting plate 30 of this structure makes the beam 100 have the following characteristics: the radial protrusion 34 is more likely to deform in the axial direction. Therefore, the mating section 20 and the main body section 10 have a larger allowable bending compliance. The applicable working conditions are: the assembly error of the beam 100 and the column 200 is predicted to be large, and it has better seismic resistance (adapting to the deformation of the main steel structure caused by vibration through elastic bending).

[0051] The third type of docking plate.

[0052] like Figure 5 and Figure 6 As shown, the connecting disc 30 includes a disc-shaped body 31 with a plurality of axial protrusions 35 formed by bending on the disc-shaped body 31. The plurality of axial protrusions 35 are arranged circumferentially at intervals, and the directions of protrusion of two adjacent axial protrusions 35 are opposite. The axial protrusions 35 facing the first mating disc 11 serve as the first connecting area 321, and the axial protrusions 35 facing the second mating disc 21 serve as the second connecting area 322. The axial protrusions 35 extend radially along the disc-shaped body 31. The axial protrusions 35 are stamped in the axial direction by a stamping die. In this structure, the first mating disc 11 and the second mating disc 21 do not need to be machined with protrusions. The surface of the axial protrusions 35 directly contacts the mating discs, and each axial protrusion 35 is screwed with two bolts.

[0053] The connecting disc 30 of this structure has an axial protrusion 35. Therefore, the connecting disc 30 of this structure gives the crossbeam 100 the following characteristics: the axial protrusion 35 protrudes axially from the disc-shaped body 31. Therefore, the axial protrusion 35 makes the connecting disc 30 more likely to deform in the circumferential direction. As a result, there is a larger allowable torsional compliance between the mating section 20 and the main body section 10. The advantage of the connecting disc 30 of this structure is that it gives the crossbeam 100 better seismic resistance (the crossbeam 100 adapts to the deformation of the steel structure caused by vibration through torsion).

[0054] In some preferred embodiments, such as Figure 2 and combined Figure 7 As shown, a central hole 33 is machined in the middle of the connecting plate 30; a connecting cylinder 40 is provided between the first connecting plate 30 and the second connecting plate 30, and the middle part of the cylinder wall of the connecting cylinder 40 is radially bent inward; the two ends of the connecting cylinder 40 have radially outward-curved outer edges, and the outer edges of the two ends of the connecting cylinder 40 are fixed to the first mating plate 11 and the second mating plate 21 by bolts. The connecting cylinder 40 with this structure has stronger conformability than the connecting plate 30. The function of the connecting cylinder 40 is that when the connection between the main body section 10 and the mating section 20 fails through the mating plate, for example, if the mating plate is damaged or the bolt at the mating plate breaks due to excessive torque and bending moment, the connecting cylinder can keep the main body section 10 connected to the connecting end. The connecting cylinder 40 is particularly suitable as a safety component in earthquake-resistant steel structure main bodies.
