Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical connection components, and more specifically, relates to a connection assembly for connecting a structural beam and a structural column. Background Art

[0002] In the field of engineering construction, structural beams and structural columns are commonly used components. Among them, connecting a structural beam between two structural columns is a more common combination of beams and columns. During the construction process, the structural beams and structural columns are usually fixed by bolts. Bolt connection has the characteristics of simple structure and convenient operation. However, under some special working conditions, such as when one side of the structural column sinks and moves down as a whole, since the beams and columns connected by traditional bolts are fixed to each other, the sinking structural column will pull the structural beam, causing internal stress in the structure connecting the structural beam and the structural column. In severe cases, this will cause the structural beam to deform or the structural column on the other side to tilt, thereby destroying the stability of the structure connecting the structural beam and the structural column. To address this problem, it is necessary to design a connector for connecting the structural beam and the structural column so that the connection between the structural beam and the structural column can swing relative to each other within a certain angle range to adapt to different force deformations, installation errors or dynamic movement requirements. Summary of the invention

[0003] The purpose of the present invention is to provide a connection assembly for connecting a structural beam and a structural column. By connecting the structural beam and the structural column, the structural beam and the structural column can achieve relative swing within a certain angle range, effectively adapt to the connection requirements under special working conditions, and improve the reliability of the connection.

[0004] To achieve the above object, the technical solution adopted by the present invention is: to provide a connection assembly for connecting a structural beam and a structural column, comprising: A connecting plate, wherein a connecting portion is provided on the connecting plate, wherein the connecting portion is used to connect the structural beam and make the connecting plate perpendicular to the axial direction of the structural beam, wherein a connecting hole is penetrated through the connecting plate, and arched convex ridges are symmetrically provided on both sides of the connecting hole, wherein the arched convex ridges are located on the end surface of the first side of the connecting plate, and the extension lines of the two arched convex ridges coincide and intersect with the central axis of the connecting hole; A stud is inserted into the connection hole, and a movable gap is provided between the circumference of the stud and the connection hole. The stud comprises a first section and a second section. The first section is located at a first side of the connection plate and is fixedly connected to the structural column. The second section is located at a second side of the connection plate. The first section and the second section are hingedly connected in the connection hole. A connecting block is inserted into the first section, and an arched groove is provided on one side of the connecting block facing the connecting plate corresponding to the arched convex ridge, the height of the arched convex ridge is greater than the depth of the arched groove, the width of the arched groove is greater than the width of the arched convex ridge, the arched convex ridge abuts against the arched groove, and a swing gap is provided between the connecting block and the connecting plate; The first locking nut is passed through the second section, and the first locking nut presses against the second side end surface of the connecting plate to limit the movement of the first section and prevent the connecting block from being separated from the connecting plate.

[0005] In a possible implementation, the connection portion is a connection sub-plate vertically connected to the connection plate, and the connection sub-plate is fixed to the structural beam by bolting or welding.

[0006] In a possible implementation manner, the connecting block and the first section are formed integrally.

[0007] In a possible implementation manner, a second locking nut is provided on the first section, and the second locking nut is used to fix the structural column between the connecting block and the second locking nut.

[0008] In a possible implementation, a connecting groove is provided at the end of the first section near the second section, a connecting shaft is provided in the connecting groove, the axial direction of the connecting shaft is consistent with the length direction of the arched ridge, and a connecting head is provided at the end of the second section near the first section, a through hole is provided on the connecting head for inserting the connecting shaft, the through hole is an elliptical hole, and the radial direction of the short diameter of the elliptical hole is the same as the axial direction of the second section.

[0009] In a possible implementation, a limiting rib is provided on the end surface of the connecting block facing the connecting plate, and the limiting rib is located on both sides of the arched groove and is used to limit the swing angle of the connecting plate relative to the connecting block.

[0010] In a possible implementation, an end surface of the limiting rib plate close to a side of the connecting plate is inclined from the inside to the outside toward a side of the connecting block.

[0011] In one possible implementation, an annular groove is provided on the end face of the second side of the connecting plate, and the annular groove is concentric with the connecting hole.

[0022] See also Figures 1 to 8, a connection assembly for connecting a structural beam and a structural column provided by the present invention is now described. The connection assembly for connecting a structural beam and a structural column comprises a connection plate 1, a stud 2, a connection block 3 and a first locking nut 4, wherein a connection portion is provided on the connection plate 1, the connection portion is used to connect the structural beam 200, and the connection plate 1 is perpendicular to the axial direction of the structural beam 200, a connection hole 101 is penetrated through the connection plate 1, and arched convex ridges 6 are symmetrically provided on both sides of the connection hole 101, and the arched convex ridges 6 are located on the end surface of the first side of the connection plate 1, and the extension lines of the two arched convex ridges 6 coincide and intersect with the central axis of the connection hole 101, the stud 2 is penetrated in the connection hole 101, and there is a movable gap between the circumference of the stud 2 and the connection hole 101, and the stud 2 comprises a first section 21 and a second section 22, wherein the first section 21 The first side of the connecting plate 1 is used for fixed connection with the structural column 100, the second section 22 is located on the second side of the connecting plate 1, the first section 21 and the second section 22 are hinged in the connecting hole 101, the connecting block 3 is penetrated on the first section 21, and the connecting block 3 is provided with an arched groove 31 corresponding to the arched rib 6 on the side facing the connecting plate 1, the height of the arched rib 6 is greater than the depth of the arched groove 31, the width of the arched groove 31 is greater than the width of the arched rib 6, the arched rib 6 abuts against the arched groove 31, and there is a swing gap between the connecting block 3 and the connecting plate 1, the first locking nut 4 is penetrated on the second section 22, and the first locking nut 4 presses against the second side end face of the connecting plate 1 to limit the movement of the first section 21 and prevent the connecting block 3 from detaching from the connecting plate 1.

[0023] The present invention provides a connection assembly for connecting a structural beam and a structural column. Compared with the prior art, the connection assembly is fixedly connected to the structural beam 200 through a connection plate 1, and connected to the structural column 100 through the first section 21 of the stud 2. When the structural column 100 on one side of the beam-column structure sinks and moves downward, the structural beam 200 can slide in the arched groove 31 in the connection block 3 (with the help of the connection plate 1) with the arched convex rib 6 on the connection plate 1 as a fulcrum, so that the structural beam 200 can swing a certain angle relative to the structural column 100 to adapt to the sinking of the structural column 100, prevent the structural beam 200 from being pulled by the structural column 100, and meet the connection requirements of the beam-column structure. In addition, since the height of the arched convex rib 6 is greater than the depth of the arched groove 31 and the arched convex rib 6 abuts against the arched groove 31, the connection block 3 can be effectively prevented from being separated from the connection plate 1. The first locking nut 4 abuts against the second side end face of the connection plate 1 to limit the movement of the first section 21, which ensures the stability of the connection. In addition, there is a movable gap between the stud 2 and the connecting hole 101 in the circumferential direction, the first section 21 and the second section 22 are hinged in the connecting hole 101, and the width of the arched groove 31 of the connecting block 3 facing the connecting plate 1 is greater than the width of the arched rib 6, which allows a swing gap between the connecting block 3 and the connecting plate 1, thereby allowing angle adjustment and relative movement within a certain range.

[0024] In this example, see Figures 1 to 8 The connecting portion provided on the above-mentioned connecting plate 1 can be a connecting sub-plate 11, and the connecting sub-plate 11 is vertically connected to the connecting plate 1. In application, a through hole can be provided on the connecting sub-plate 11, and the connecting sub-plate 11 and the connecting plate 1 are connected to the structural beam 200 by bolts, or the connecting sub-plate 11 can be fixed to the structural beam 200 by welding. In this embodiment, the connecting plate 1 and the connecting sub-plate 11 can be fixed by welding, or they can be made of the same steel plate after bending. In order to improve the structural strength between the connecting plate 1 and the connecting sub-plate 11, a reinforcing rib (not shown in the figure) can be provided between the connecting plate 1 and the connecting sub-plate 11.

[0025] In some embodiments, see Figure 1 to Figure 2 The above-mentioned connecting block 3 can be a block structure threadedly connected to the first section 21, so that the connecting block 3 and the first section 21 can be detachably connected through threads, which can facilitate the maintenance and replacement of the connecting block 3.

[0026] In some embodiments, see Figures 1 to 8 The connecting block 3 can also be a block structure fixedly connected to the first section 21. The connecting block 3 and the first section 21 can be fixed by welding, or the two can be integrally formed. Such a setting can make the connection between the connecting block 3 and the first section 21 more reliable, prevent the connection between the connecting block 3 and the first section 21 from loosening during use, and thus avoid affecting the abutting relationship between the connecting block 3 and the arched convex rib 6.

[0027] Furthermore, the connecting block 3 can be a square block or a polygonal block structure. Such a configuration can facilitate operators to use tools to fix the connecting block 3, thereby preventing the connecting block 3 from rotating during installation and ensuring that the arched groove 31 on the connecting block 3 can correspond to the arched ridge 6 on the connecting plate 1.

[0028] In the application, see Figure 8 Some structural columns 100 are provided with connecting wing plates 110. In order to enable the first section 21 to be connected to the connecting wing plates 110, a second locking nut 5 is passed through the first section 21. When in use, the first section 21 passes through the reserved hole on the connecting wing plate 110. By rotating the second locking nut 5, the connecting wing plate 110 can be fastened between the connecting block 3 and the second locking nut 5, so that the second section 22 is connected and fixed to the structural column 100.

[0029] In some embodiments, see Figures 5 to 7The first section 21 and the second section 22 of the stud 2 can be connected by the following structure. Specifically, a connecting groove 211 is provided at the end of the first section 21 close to the second section 22. In this embodiment, the opening direction of the connecting groove 211 is perpendicular to the opening direction of the arched groove 31 on the connecting block 3. A connecting shaft 7 is provided in the connecting groove 211. The axial direction of the connecting shaft 7 is parallel to the length direction of the arched convex rib 6. A connecting head 221 is provided at the end of the second section 22 close to the first section 21. The connecting head 221 is provided with a through hole 8 for inserting the connecting shaft 7. In order to compensate the total length of the stud 2 when the connecting plate 1 and the connecting block 3 swing relative to each other, the above-mentioned through-hole 8 is set as an elliptical hole, and the radial direction of the short diameter of the elliptical hole is set to be the same as the axial direction of the second section 22. In this way, when the structural beam 200 drives the connecting plate 1 to swing a certain angle, with the help of the connecting shaft 7 and the elliptical hole, the second section 22 can rotate with the connecting plate 1 around the connecting shaft 7, and at the same time, the connecting shaft 7 can slide relatively in the elliptical hole along the long diameter direction of the elliptical hole, thereby generating a compensating displacement, so that the total length of the stud 2 can be compensated.

[0030] In some embodiments, see Figures 1 to 8 A limiting rib 32 is provided on the end surface of the connecting block 3 facing the connecting plate 1. The limiting rib 32 is located on both sides of the arched groove 31. The height of the limiting rib 32 is less than the swing gap between the connecting plate 1 and the connecting block 3. By controlling the height of the limiting rib 32, the swing angle of the connecting plate 1 relative to the connecting block 3 can be limited to avoid excessive swing angle. In addition, the rigidity of the connecting block 3 is also enhanced by setting the limiting rib 32, so that the connecting block 3 is more stable when pressed by the inclined connecting plate 1 and is not easy to bend or deform.

[0031] In this embodiment, the end face of the limiting rib 32 close to the connecting plate 1 is inclined from the inside to the outside toward the connecting block 3. In this way, the inclined connecting plate 1 can make surface-to-surface contact with the inclined surface of the limiting rib 32, thereby increasing the contact area between the connecting plate 1 and the limiting rib 32, dispersing the force of the connecting plate 1 on the limiting rib 32, and thereby evenly distributing the force on the connecting block 3 and improving the stability of the connecting block 3.

[0032] In some embodiments, see Figures 5 to 7 An annular groove 102 is provided on the end face of the second side of the above-mentioned connecting plate 1, and the annular groove 102 is concentric with the connecting hole 101. An annular convex ridge 41 is provided on the end face of the first locking nut 4 facing the connecting plate 1 corresponding to the annular groove 102. In application, the annular convex ridge 41 is inserted into the annular groove 102 to limit the sliding between the first locking nut 4 and the connecting plate 1.

[0033] Furthermore, in order to prevent the first locking nut 4 from loosening during use, a spring washer may be provided between the first locking nut 4 and the connecting plate 1 .

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
