Description

Technical Field

[0001] The invention relates to a load-bearing component of a building, in particular to a transverse connecting device of a steel structure column. Background Art

[0002] In the process of constructing the main body of the steel structure, a process of horizontally connecting two columns by using a crossbeam (the crossbeam is a secondary load-bearing beam or a non-load-bearing beam) is usually involved. In the prior art, a substantially rigid crossbeam is usually used to connect the two columns. Specifically, a butt joint surface is configured at both ends of the crossbeam, and a mounting surface is processed on the surface of each column. First, the butt joint surface of the first end of the crossbeam is butted against the mounting surface of the first column, and the first end of the crossbeam is fixed to the first column by a fastener. Then, the butt joint surface of the second end of the crossbeam is butted against the mounting surface of the second column, and the second end of the crossbeam is fixed to the second column by a fastener.

[0003] The above-mentioned connection structure between the crossbeam and the column has the following defects during installation and subsequent use: Since the verticality error between the crossbeam and the column is inevitable, in the process of fixing the second end of the crossbeam to the second column, the docking surface of the second end and the mounting surface of the second column are not parallel in the initial state when docking, which results in the need to increase the tension of the bolts in the corresponding area to correct the non-parallel state of the two as much as possible, and to make the docking surface and the mounting surface dock in full contact as much as possible. However, this will cause harmful internal stress between the column and the crossbeam, and the bolts in the corresponding area are prone to break due to excessive stretching. These harmful results are particularly prone to occur when the main body of the steel structure vibrates. Therefore, the seismic effect of the above-mentioned connection structure between the crossbeam and the column is poor.

[0004] In order to solve the above problems, in the prior art, the crossbeam is divided into two sections at the position close to the column, and the two sections of the crossbeam are connected by a circumferentially arranged columnar spring, which enables the butt joint surface of the end of the crossbeam to be compliantly adjusted to avoid excessive tension added by the bolt. However, due to the poor shear resistance of the columnar spring, the relative torsion and bending between the two sections of the crossbeam cannot be effectively suppressed, resulting in the crossbeam's torsional rigidity and bending rigidity being too small, and then resulting in the crossbeam's support rigidity and strength being too low. Summary of the invention

[0005] In view of the above technical problems existing in the prior art, an embodiment of the present invention provides a transverse connection device for steel structure columns.

[0006] In order to solve the above technical problems, the technical solution adopted in the embodiments of the present invention is: A transverse connection device for a steel structure column, comprising: A column, the outer surface of which is processed to form a mounting surface; The crossbeam comprises a main body section and a docking section; a docking surface is configured at one end of the docking section away from the main body section, and the docking surface is used to dock with the mounting surface and be fixed by bolts; wherein: A first docking plate is configured at the end of the main body section opposite to the docking section, and a second docking plate is configured at the end of the docking section opposite to the main body section; A connecting plate is provided between the first docking plate and the second docking plate; The connection disk has a plurality of first connection areas connected to the first docking disk, and the plurality of first connection areas are arranged at intervals along the circumferential direction; the connection disk has a plurality of second connection areas connected to the second docking disk, and the plurality of second connection areas are arranged at intervals along the circumferential direction; the second connection areas are arranged alternately with the first connection areas.

[0008] Preferably, the connection disk comprises a disk-shaped body, and a plurality of radial protrusions arranged circumferentially are configured by removing material from an edge of the disk-shaped body, and the radial protrusions alternately serve as the first connection area and the second connection area.

[0009] Preferably, the connecting disk includes a disk-shaped body, and a plurality of axial protrusions formed by bending are arranged on the disk-shaped body, the plurality of axial protrusions are arranged circumferentially at intervals, and the protruding directions of two adjacent axial protrusions are opposite; the axial protrusion facing the first docking disk serves as the first connection area, and the axial protrusion facing the second docking disk serves as the second connection area.

[0010] Preferably, the axial protrusion extends in the radial direction of the disc-shaped body; and the axial protrusion is stamped in the axial direction by a stamping die.

[0011] Preferably, a first boss is configured at a position of the first docking tray corresponding to the first connection area, and the first boss is combined with the first connection area; a second boss is configured at a position of the second docking tray corresponding to the second connection area, and the second boss is combined with the second connection area, so that the disc-shaped body and the first docking tray and the second docking tray have a predetermined gap.

[0012] Preferably, the first connection area and the first docking plate are fixed by bolts passing through both, and the second connection area and the second docking plate are fixed by two types of bolts passing through.

[0013] Preferably, a center hole is processed in the middle of the connecting disk; a connecting tube is arranged between the first connecting disk and the second connecting disk, and the middle part of the tube wall of the connecting tube is radially bent inward; both ends of the connecting tube have radially outward-turned outer edges, and the outer edges of both ends of the connecting tube are fixed to the first docking disk and the second docking disk by bolts.

[0014] Preferably, a rectangular docking plate is arranged at one end of the docking section away from the main body section, and the docking surface is formed on an outer plate surface of the rectangular docking plate.

[0015] Preferably, a vertically extending positioning groove is processed on the outer surface of the column, and the bottom of the positioning groove serves as the mounting surface.

[0016] Compared with the prior art, the beneficial effects of the transverse connection device of the steel structure column disclosed in the present invention are: The crossbeam connection device provided by the present invention reduces the internal stress between the crossbeam and the column, and reduces the tension of the bolts in the corresponding area. Therefore, when the main body of the steel structure vibrates, the bolts in the corresponding area of ​​the docking surface and the installation surface are not easy to break.

[0028] In order to keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and well-known components are omitted.

[0029] The embodiment of the present invention discloses a transverse connection device for steel structure columns, which is used to connect a beam 100 between two columns 200. The device is particularly suitable for the transverse connection of non-load-bearing beams 100. Figures 1 to 6 As shown, the device includes: a column 200 and a beam 100.

[0030] The column 200 is a square tubular column 200 having four flat surfaces. Vertically extending positioning grooves 202 are processed on the opposite surfaces of two columns 200 , and the bottom of the positioning groove 202 is processed into a mounting surface 201 .

[0031] The crossbeam 100 includes a main section 10 and docking sections 20 located on both sides of the main section 10 (only the docking section 20 on one side of the main section 10 is shown in the accompanying drawings). The main part of the main section 10 is an I-shaped steel profile, and the main part of the docking section 20 is also an I-shaped steel profile. A first docking plate 11 is fixed to the end of the main section 10 by welding, and a second docking plate 21 is fixed to the end of the docking section 20 opposite to the main section 10 by welding. A rectangular docking plate 22 is fixed to the end of the docking section 20 away from the main section 10 by welding. A docking surface 221 is processed on the outer plate surface of the rectangular docking plate 22, so that the rectangular docking plate 22 is embedded in the positioning groove 202, so as to make the docking surface 221 fit with the mounting surface 201 of the groove bottom of the positioning groove 202, and the rectangular docking plate 22 is penetrated by bolts and screwed into the column 200 to achieve docking and fixation between the rectangular docking plate 22 and the column 200.

[0032] In the present invention, a connection plate 30 is arranged between the first docking plate 11 of the main body section 10 and the second docking plate 21 of the docking section 20. The docking plate is divided into a plurality of first connection areas 321 and a plurality of second connection areas 322. The plurality of first connection areas 321 are arranged circumferentially at intervals, and the plurality of second connection areas 322 are arranged circumferentially at intervals. The first connection areas 321 and the second connection areas 322 are arranged alternately in the circumferential direction. A plurality of bolts are arranged circumferentially on the first docking plate 11, and the plurality of bolts are screwed into the first connection areas 321 respectively, so that the connection plate 30 is connected to the first docking plate 11 through the circumferentially arranged first connection areas 321. A plurality of bolts are also arranged circumferentially on the second docking plate 21, and the plurality of bolts are screwed into the second connection areas 322 respectively, so that the connection plate 30 is connected to the second docking plate 21 through the circumferentially arranged second connection areas 322. In this way, the first docking plate 11 and the second docking plate 21 are connected through the connection plate 30. Since the adjacent first connection area 321 and the second connection area 322 are connected to the first docking tray 11 and the second docking tray 21 respectively, the relative posture of the first docking tray 11 and the second docking tray 21 can be sequentially changed through micro-deformation of the area between the first connection area 321 and the second connection area 322.

[0033] In the process of connecting the crossbeam 100 to the two columns 200, first, the rectangular docking plate 22 of the docking section 20 at the first end of the crossbeam 100 is docked with the mounting surface 201 of the first column 200 and fixed by bolts, and then the rectangular docking plate 22 of the docking section 20 at the second end of the crossbeam 100 is directed toward the mounting surface 201 of the second column 200 and fixed by bolts. If the docking surface 221 of the docking section 20 at the second end of the crossbeam 100 and the mounting surface 201 of the column 200 are in a non-parallel state, this state is corrected by tightening the bolts so that the docking 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 docking plate 11 and the second docking plate 21 are connected by the connecting plate 30, the connecting plate 30 undergoes a micro-elastic deformation, which can make the docking section 20 produce a compliant bending relative to the main section 10. Therefore, the bolts make the docking surface 221 and the mounting surface 201 attached as a whole without increasing excessive tension, thereby reducing the internal stress between the crossbeam 100 and the column 200, and reducing the tension of the bolts in the corresponding area. Therefore, when the main body of the steel structure vibrates, the bolts in the corresponding area of ​​the docking surface 221 and the mounting surface 201 are not easy to break. In addition, when vibration occurs, the connection structure of the two docking plates and the connecting plate 30 enables the docking section 20 and the main section 10 to have a certain anti-seismic effect. It is important that: since the structure of the connecting plate 30 is basically a disc-shaped structure, the connection structure between the two docking plates and the connecting plate 30 has a shear resistance stronger than that of a spring, and thus can have a sufficient inhibitory effect on the torsion and bending of the beam 100 to avoid excessive bending and torsion during earthquake resistance.

[0034] In addition, the main section 10 and the docking section 20 of the cross beam 100 are connected via a docking plate, which is simpler to install than arranging a plurality of columnar springs in a circumferential direction.

[0035] The present invention provides docking plates with three structures.

[0036] The docking plate of the first structure.

[0037] like Figure 1 and Figure 2As shown, the connection plate 30 includes a disk-shaped body 31 made of a high elastic modulus metal plate, and the first connection area 321 and the second connection area 322 are located at the edge of the disk-shaped body 31. The first connection plate 11 is processed with a first boss 111 at a position corresponding to each first connection area 321, and the corresponding bolt is passed through the first boss 111 and screwed into the threaded hole of the first connection area 321, so that the first boss 111 is combined with the surface of the first connection area 321, and the second connection plate 21 is processed with a second boss 211 at a position corresponding to each second connection area 322, and the corresponding bolt is passed through the second boss 211 and screwed into the threaded hole of the second connection area 322, so that the second boss 211 is combined with the surface of the second connection area 322. In this way, the first connection plate 11 and the second connection plate 21 are combined with the connection plate 30 through the boss, so that a predetermined gap is formed between the connection plate 30, and the predetermined gap is used as a reserved gap to allow the docking section 20 to bend relative to the main section 10.

[0038] The connecting plate 30 of the present structure is basically a flat disc-shaped structure. Therefore, the connecting plate 30 of the present structure enables the beam 100 to have the following characteristics: the allowed bending compliance and torsional compliance between the docking section 20 and the main section 10 are both small, and the bending resistance and torsional resistance are both strong. The applicable working conditions are: the assembly error between the beam 100 and the column 200 is predicted to be small, and the beam 100 is required to have greater rigidity.

[0039] The docking plate of the second structure.

[0040] like Figure 3 and Figure 4 As shown, the connecting disk 30 includes a disk-shaped body 31, and a plurality of radial protrusions 34 arranged circumferentially are configured by removing material from the edge of the disk-shaped body 31. The radial protrusions 34 alternately serve as the first connection area 321 and the second connection area 322. The first docking disk 11 and the second docking disk 21 are also processed with first bosses 111 and second bosses 211 respectively corresponding to the first connection area 321 and the second connection area 322, so as to provide a reserved gap for the docking section 20 to bend relative to the main section 10, and the bolts respectively pass through the first bosses 111 and the second bosses 211 and are screwed into the threaded holes of the radial protrusions 34.

[0041] The connecting plate 30 of the present structure has a radial protrusion 34, and thus, the connecting plate 30 of the present structure enables the cross beam 100 to have the following characteristics: the radial protrusion 34 is more likely to deform in the axial direction, and thus, there is a larger allowable bending compliance between the docking section 20 and the main section 10, and the applicable working conditions are: it is predicted that the assembly error between the cross beam 100 and the column 200 is large, and it has better earthquake resistance (complying with the deformation of the steel structure body caused by vibration by elastic bending).

[0042] The docking plate of the third structure.

[0043] like Figure 5 and Figure 6 As shown, the connection disk 30 includes a disk-shaped body 31, on which a plurality of axial protrusions 35 formed by bending are arranged, the plurality of axial protrusions 35 are arranged circumferentially at intervals, and the protrusions of two adjacent axial protrusions 35 are in opposite directions; the axial protrusions 35 facing the first docking disk 11 serve as the first connection area 321, and the axial protrusions 35 facing the second docking disk 21 serve as the second connection area 322, and the axial protrusions 35 extend radially along the disk-shaped body 31; the axial protrusions 35 are stamped and formed in the axial direction by a stamping die. In this structure, the first docking disk 11 and the second docking disk 21 do not need to be processed with a boss, and the surface of the axial protrusion 35 directly contacts the docking disk, and each axial protrusion 35 is screwed with two bolts.

[0044] The connecting disk 30 of the present structure has an axial protrusion 35, and thus, the connecting disk 30 of the present structure enables the cross beam 100 to have the following characteristics: the axial protrusion 35 protrudes axially from the disc-shaped body 31, and thus, the axial protrusion 35 makes it easier for the connecting disk 30 as a whole to deform in the circumferential direction, and thus, there is a larger allowed torsional compliance between the docking section 20 and the main section 10. The connecting disk 30 of the present structure has the advantage that it enables the cross beam 100 to have better earthquake resistance (the cross beam 100 complies with the deformation of the steel structure body caused by vibration through torsion).

[0045] In some preferred embodiments, Figure 2 Combined with Figure 7 As shown, a center hole 33 is processed in the middle of the connecting disk 30; a connecting tube 40 is arranged between the first connecting disk 30 and the second connecting disk 30, and the middle part of the tube wall of the connecting tube 40 is radially bent inward; both ends of the connecting tube 40 have radially turned outward outer edges, and the outer edges of both ends of the connecting tube 40 are fixed to the first docking disk 11 and the second docking disk 21 by bolts. The compliance of the connecting tube 40 of this structure is stronger than that of the connecting disk 30. The function of the connecting tube 40 is: when the connection between the main section 10 and the docking section 20 through the docking disk fails, for example, if the docking disk is damaged or the bolts at the docking disk are broken due to excessive torque and bending moment, the connecting tube can keep the main section 10 and the connecting end connected. As a safety component, the connecting tube 40 is particularly suitable for earthquake-resistant steel structure bodies.
