Description

Technical Field

[0001] The present application relates to the field of prefabricated buildings, and in particular to prefabricated building beam-column steel structure connection components. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods.

[0003] Beam-column structure is an indispensable component in construction. At present, when constructing beam-column structure of prefabricated building, the steel structure column is hoisted first, and then the steel structure beam is hoisted. The two ends of the steel structure beam are connected and fixed with the connecting plates pre-fixed on the side walls of the steel structure column by fasteners.

[0004] The steel structure beam is installed between two adjacent steel structure columns. Although the steel structure columns are usually adjusted in verticality during installation so that the two adjacent steel structure columns remain parallel to each other, when the steel structure columns are installed, although the steel structure columns are installed as far as possible according to the predetermined distribution position, there are inevitably errors in the installation position of the steel structure columns, resulting in an alignment error between the connecting plates located on the side walls of the two adjacent steel structure columns. As a result, when the two ends of the steel structure beam are respectively installed correspondingly to the two adjacent connecting plates, it is difficult for the steel structure beam and the connecting plate to fit together, that is, a certain angle is formed. If fasteners are used for strong tightening later, on the one hand, it increases the work intensity of the staff in locking the fasteners, and on the other hand, it is easy to cause deformation and damage to the connection between the connecting plate and the steel structure column. Summary of the invention

[0005] In order to reduce the problem of increased work intensity and deformation and damage at the connection parts between the connecting plate and the steel structure column caused by the difficulty of steel structure beams to fit together with the connecting plates during installation, the present application provides a prefabricated building beam-column steel structure connecting component.

[0006] The prefabricated building beam-column steel structure connection member provided in this application adopts the following technical solution:

[0007] The prefabricated building beam-column steel structure connecting component includes a connecting plate and a plurality of fastening components, wherein a hinge for connecting the steel structure column is provided on one side of the connecting plate, and the fastening component is used to connect the connecting plate and the steel structure beam; the connecting plate is provided with an auxiliary connecting plate, and the auxiliary connecting plate includes a transverse plate portion and a longitudinal plate portion, the transverse plate portion and the longitudinal plate portion are perpendicular to each other, an arc transition portion is provided between the transverse plate portion and the longitudinal plate portion, the transverse plate portion is fixedly connected to the connecting plate, and the longitudinal plate portion is used to be fixedly connected to the side wall of the steel structure column.

[0008] By adopting the above technical scheme, two adjacent connecting plates are respectively connected to the steel structure beam, and the connecting plates are locked and connected to the steel structure beam through a fastening assembly. When there is an alignment error between the two adjacent connecting plates, the steel structure beam forces the two connecting plates to be parallel to each other, so that the relative angle between the connecting plate and the steel structure column changes. Since the connecting plate is connected to the steel structure column through a hinge, the relative angle change between the connecting plate and the steel structure column can be achieved by a small angle rotation of the connecting plate, rather than by deformation of the connecting portion between the connecting plate and the steel structure column, which is beneficial to reduce damage to the connecting portion between the connecting plate and the steel structure column.

[0009] In addition to being connected to the steel structure column through the hinge, the connecting plate is also fixedly connected to the steel structure column through the auxiliary connecting plate. The transverse plate portion of the auxiliary connecting plate is fitted and fixed to the crossbeam, and the longitudinal plate of the auxiliary connecting plate is fitted and fixed to the steel structure column. Compared with the hinged connection method of the hinge, the auxiliary connecting plate has a more stable connection effect on the connecting plate and the steel structure column, which is beneficial to ensuring the stability of the connection between the connecting plate and the steel structure column; in addition, when the relative angle between the connecting plate and the steel structure column changes, the arc transition portion of the auxiliary connecting plate can be deformed to adapt to the angle change between the transverse plate portion and the longitudinal plate portion. Compared with the welded connection between the connecting plate and the steel structure column in conventional means, the arc transition portion is easier to deform and is not easy to break due to stress concentration during the deformation process, so that the staff needs to overcome less resistance to lock the connecting plate and the crossbeam through the fastening assembly, which is beneficial to reduce the labor intensity of the staff to lock the fastening assembly, and at the same time, the arc transition portion is not easy to be damaged after deformation.

[0010] Optionally, the hinged part includes an hinge seat and an hinge shaft, the diameter of the hinge shaft is larger than the thickness of the connecting plate, the hinge shaft is fixedly connected to the connecting plate, the hinge seat is provided with a hinge groove for hinged connection of the hinge shaft, the hinge groove is an arc groove, and the arc angle of the groove wall of the hinge groove is larger than the straight angle.

[0011] By adopting the above technical solution, the hinge shaft of the hinged member is directly fixedly connected to the connecting plate, which is conducive to realizing a hinged connection between the connecting plate and the steel structure column with a relatively simple structure. The arc angle of the hinge groove is greater than the flat angle, so that the hinge shaft can be kept inside the arc groove.

[0012] Optionally, a side of the connecting plate close to the hinge shaft is provided with a plurality of protruding teeth, and an outer peripheral wall of the hinge shaft is provided with a plurality of slots for correspondingly inserting the protruding teeth, and the slots are arranged in sequence along the axial direction of the hinge shaft.

[0013] By adopting the above technical solution, the staggered meshing connection between the connecting plate and the hinge shaft is achieved through the insertion and adaptation between the convex teeth and the slots, so that the connecting plate and the hinge shaft can better transmit the axial force of the hinge shaft, so that the hinge part between the connecting plate and the steel structure column can better withstand the load of the steel structure beam.

[0014] Optionally, the articulated seat includes a seat body and an articulated tube, the articulated tube is fixedly connected to the seat body, the outer peripheral wall of the articulated tube is provided with a cutting groove, the bottom of the cutting groove is connected to the inner cavity of the articulated tube, and the area of ​​the inner cavity of the articulated tube exposed to the cutting groove serves as the articulated groove, the length of the articulated shaft is greater than the axial dimension of the connecting plate along the articulated shaft, and greater than the length of the articulated groove, the connecting plate is located between the two end surfaces of the articulated shaft, and the cutting groove is located between the two end surfaces of the articulated shaft.

[0015] By adopting the above technical solution, the articulated seat is made of a seat body and an articulated tube, and the articulated groove is formed by cutting the peripheral wall of the articulated tube, so that the forming process of the articulated groove is relatively fast. In addition, the articulated tube can be made of standard parts, and it is convenient to obtain materials. The length of the articulated shaft is greater than the length of the connecting plate and the cutting groove, and the articulated groove is located between the two end surfaces of the articulated shaft, so that the two ends of the articulated shaft are respectively located in the closed areas around the two ends of the articulated tube, so that the articulated tube has a good restraining effect on the articulated shaft.

[0016] Optionally, the hinged tube is provided with two metal springs, which are symmetrically arranged along the center line of the hinged tube, one side of the metal spring is fixedly connected to the hinged tube, and the side of the metal spring away from the fixed side is inclined to abut the wide surface of the connecting plate.

[0017] By adopting the above technical solution, the two metal spring sheets fixed on the hinged tube respectively abut against the connecting plates, so that the two metal spring sheets respectively form a limiting effect on the hinged seat, making it difficult for the hinged seat to rotate relative to the connecting plate, so that the side of the seat body away from the connecting plate is flush with the side of the longitudinal plate parts of the two auxiliary connecting plates away from the transverse plate parts, so that the seat body and the longitudinal plate parts of the two auxiliary connecting plates can fit the surface of the steel structure column at the same time.

[0018] Optionally, it also includes a positioning steel bar ring, which is used to surround and fix on the steel structure column, and the positioning steel bar ring is provided with a positioning notch for avoiding the seat body.

[0019] By adopting the above technical solution, when the hinged seat is fixedly connected to the steel structure column, the positioning ring steel bar can be used for positioning, so that the position of the hinged seat on the side wall of the steel structure column is not easy to change during the installation process, which is conducive to making the position of the hinged seat after fixing as close as possible to the predetermined installation position.

[0020] Optionally, two auxiliary connecting plates are provided, and the two auxiliary connecting plates are respectively located on two opposite sides of the connecting plate, and the dimension of the auxiliary connecting plate along the axial direction of the hinge axis is less than or equal to half of the dimension of the connecting plate along the axial direction of the hinge axis, and the two auxiliary connecting plates are staggered along the axial direction of the hinge axis.

[0021] By adopting the above technical solution, two auxiliary connecting plates are provided, so that the load is transmitted between the steel structure beam and the steel structure column through the two auxiliary connecting plates, which is conducive to making the load between the steel structure column and the steel structure beam more balanced. The dimension of the auxiliary connecting plate along the axial direction of the hinge axis is smaller than the dimension of the connecting plate along the axial direction of the hinge axis, so that the hinge seat is exposed to facilitate the connection between the hinge seat and the steel structure column. The two auxiliary connecting plates are staggered in the height direction after the hinge is free, which is convenient for connecting various parts of the hinge seat along the axial direction of the hinge axis.

[0022] Optionally, there are multiple fastening components, each of which includes bolts and nuts. The bolts are used to be simultaneously penetrated and connected to the connecting plate and the steel structure beam, and each of the nuts is commonly connected to a positioning member, and the positioning member includes multiple positioning frames. The shape of the positioning frames is adapted to the contour shape of the nuts, and each of the positioning frames is arranged in a one-to-one correspondence with each of the nuts. The positioning frames are sleeve-connected with the corresponding nuts, and a connecting rod is connected between every two adjacent positioning frames. The connecting rod includes a bending section located in the middle and straight rod sections located at both ends of the bending section.

[0023] By adopting the above technical solution, each nut is positioned by the positioning frame of the positioning member, so that when the bolt and the corresponding nut need to be locked, there is no need to use tools such as wrenches and sockets to position the nut, so that the connection process between the bolt and the nut is more convenient; adjacent positioning frames are connected by connecting rods, and by making the connecting rods have bending sections, when the position between adjacent nuts deviates from the predetermined position, the connecting rod can be deformed along its own length direction to compensate for the position deviation between adjacent nuts.

[0024] Optionally, the bolt includes a bolt body and a bolt cap, and the bolt caps of each bolt are commonly wound with a synchronous traction rope, and the synchronous traction rope is provided with a plurality of spiral coils, and each of the spiral coils is respectively arranged in one-to-one correspondence with each of the bolt caps, and there is friction damping between the spiral coils and the bolt caps, and the synchronous traction rope is provided with a plurality of wire tie rings, and each of the wire tie rings is respectively arranged in one-to-one correspondence with each of the spiral coils, and both ends of the spiral coils are simultaneously connected with the wire tie rings.

[0025] By adopting the above technical solution, the bolt caps of each bolt are wrapped with a traction rope together. When one of the bolts rotates, the bolt can drive the other bolts to rotate through the synchronous traction rope. In the initial stage of installing the connecting plate and the steel structure beam using the fastening assembly, the other bolts can be driven to rotate synchronously by rotating one bolt. When any group of bolts and nuts are close to the locking state, the traction rope is removed and then locked separately. The above process can greatly improve the locking efficiency of the fastening assembly.

[0026] Optionally, a longitudinal section is provided on the outer convex side of the circular arc transition portion, and the longitudinal section intersects with the thickness surface where the two arc edges of the circular arc transition portion are located.

[0027] By adopting the above technical solution and arranging a longitudinal section at the arc transition, the arc transition portion of the auxiliary connecting plate is more easily deformed to adapt to the angle change between the connecting plate and the steel structure column.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. The connecting plate is connected to the steel structure column through a hinge, so that the relative angle change between the connecting plate and the steel structure column can be achieved through a small angle rotation of the connecting plate, which is conducive to reducing damage to the connection between the connecting plate and the steel structure column. The auxiliary connecting plate has a more stable connection between the connecting plate and the steel structure column, which is conducive to ensuring the stability of the connection between the connecting plate and the steel structure column; the arc transition part of the auxiliary connecting plate can be deformed, and the resistance that the staff needs to overcome to lock the connecting plate and the beam through the fastening component is smaller, which is conducive to reducing the labor intensity of the staff to lock the fastening component, and at the same time, the arc transition part is not easy to be damaged after deformation.

[0030] 2. The hinge shaft of the hinge is directly fixedly connected to the connecting plate, which is conducive to the connection between the connecting plate and the steel structure column to achieve a hinged connection with a relatively simple structure. The arc angle of the hinge groove is greater than the flat angle, so that the hinge shaft can be kept inside the arc groove.

[0031] 3. Each nut is positioned by the positioning frame of the positioning piece, so when the bolt and the corresponding nut need to be locked, there is no need to use tools such as wrenches and sockets to position the nut, making the connection process between the bolt and the nut more convenient.

DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-6 This application is described in further detail.

[0040] Example 1

[0041] The present application embodiment discloses a prefabricated building beam-column steel structure connection member. Figure 1 The prefabricated building beam-column steel structure connection member includes a connection plate 1, an auxiliary connection plate 2 and four fastening components 3. A hinge 4 for connecting a steel structure column 30 is provided on one side of the connection plate 1. The fastening component 3 is used to connect the connection plate 1 with the steel structure beam 20; the auxiliary connection plate 2 is used to connect the connection plate 1 with the steel structure column 30. The dimensions of the connection plate 1 and the auxiliary connection plate 2 along the hinge centerline direction of the hinge 4 are defined as height dimensions.

[0042] The steel structure beam 20 of the prefabricated building is installed between adjacent steel structure columns 30 through the beam-column steel structure connecting member. Before the steel structure beam 20 is installed, the hinge 4 and the auxiliary connecting plate 2 of the beam-column steel structure connecting member are pre-welded and positioned on the side wall of the steel structure column 30, and then the steel structure beam 20 is hoisted and connected to the corresponding connecting plate 1 using the fastening assembly 3.

[0043] When the fastening assembly 3 is being locked, if the installation position of the adjacent steel structure column 30 deviates from the ideal installation position, the steel structure beam 20 forces the two connecting plates 1 to undergo a small degree of angular deformation to fit the surface of the steel structure beam 20 during the process of locking the steel structure beam 20 and the connecting plate 1 using the fastening assembly 3. During the process of the connecting plate 1 undergoing angular deformation, the hinge 4 can make the connecting plate 1 easier to rotate, and the auxiliary connecting plate 2 can ensure the connection strength between the connecting plate 1 and the steel structure column 30.

[0044] Reference Figure 2 The auxiliary connecting plate 2 includes a transverse plate portion 21 and a longitudinal plate portion 22. The transverse plate portion 21 and the longitudinal plate portion 22 are perpendicular to each other. An arc transition portion 23 is provided between the transverse plate portion 21 and the longitudinal plate portion 22. A longitudinal section 231 is provided on the outer convex side of the arc transition portion 23. The longitudinal section 231 intersects with the thickness surface where the two arc edges of the arc transition portion 23 are located. The transverse plate portion 21 is bonded and welded to the connecting plate 1, and the longitudinal plate portion 22 is used to be bonded and welded to the side wall of the steel structure column 30.

[0045] When the connection plate 1 is deformed at an angle, the angle between the horizontal plate portion 21 and the vertical plate portion 22 of the auxiliary connection plate 2 changes accordingly. The horizontal plate portion 21 and the vertical plate portion 22 are connected by the arc transition portion 23, so that the angle change between the horizontal plate portion 21 and the vertical plate portion 22 is achieved through the deformation of the arc transition portion 23. The arc transition portion 23 is an arc-shaped structure, which is easier to deform and is not easy to break due to stress concentration during the deformation process. In addition, the longitudinal section 231 provided on the convex side of the arc transition portion 23 can also make the arc transition portion 23 easier to deform.

[0046] Reference Figure 2 and Figure 3 The hinge 4 includes a hinge seat 41 and a hinge shaft 42. The diameter of the hinge shaft 42 is greater than the thickness of the connecting plate 1. The connecting plate 1 is provided with a plurality of equally spaced protruding teeth 11 on one side of the hinge shaft 42 along its own height direction. The outer peripheral wall of the hinge shaft 42 is provided with a plurality of slots 421 equally spaced along the axial direction. The bottom wall and the side wall of the slots 421 penetrate the peripheral wall of the hinge shaft 42. The slots 421 are provided for the corresponding insertion of the protruding teeth 11. The slots 421 are arranged in sequence along the axial direction of the hinge shaft 42. The hinge shaft 42 is fixed to the connecting plate 1 by welding. The angle area formed between the outer peripheral wall of the hinge shaft 42 and the thickness surface of the connecting plate 1 is filled with weld metal.

[0047] Reference Figure 3 and Figure 4The hinge seat 41 includes a seat body 411 and a hinge tube 412. Circular plates 413 are welded and fixed at both ends of the hinge tube 412. The hinge tube 412 is welded and fixed to the seat body 411. The outer peripheral wall of the hinge tube 412 is provided with a cutting groove 4121. The groove bottom of the cutting groove 4121 is connected to the inner cavity of the hinge tube 412. The area of ​​the inner cavity of the hinge tube 412 exposed from the cutting groove 4121 is set as the hinge groove 4122. The arc angle of the groove wall of the hinge groove 4122 is greater than the straight angle. The hinge groove 4122 is provided for hinge connection of the hinge shaft 42. The length of the hinge shaft 42 is greater than the axial dimension of the connecting plate 1 along the hinge shaft 42, and is greater than the length of the hinge groove 4122. The connecting plate 1 is located between the two end surfaces of the hinge shaft 42. The cutting groove 4121 is located between the two end surfaces of the hinge shaft 42, so that both ends of the hinge shaft 42 are located in the circumferentially closed position of the hinge tube 412, so that the hinge tube 412 forms an effective restraining effect on the two ends of the hinge shaft 42.

[0048] Reference Figure 3 The hinged tube 412 is provided with two metal springs 43, which are symmetrically arranged along the center line of the hinged tube 412, and are respectively located at two opposite sides of the connecting plate 1. One side of the metal spring 43 is welded and fixed to the hinged tube 412, and the side of the metal spring 43 away from the fixed side is inclined to abut against the wide surface of the connecting plate 1. The metal spring 43 can prevent the seat body 411 of the hinged seat 41 from rotating relative to the connecting plate 1, so as to make the side of the seat body 411 away from the connecting plate 1 and the side of the longitudinal plate portion 22 of the auxiliary connecting plate 2 away from the transverse plate portion 21 keep flush, so as to facilitate welding and fixing the beam-column steel structure connector to the steel structure column 30.

[0049] Reference Figure 1 The fastening assembly 3 includes bolts 31 and nuts 32. The bolts 31 are used to be connected to the connecting plate 1 and the steel structure beam 20 at the same time. Each nut 32 is commonly connected to a positioning member 33. The positioning member 33 is a metal member. The positioning member 33 includes four positioning frames 331. The shape of the positioning frame 331 is adapted to the contour shape of the nut 32. Each positioning frame 331 is arranged in a one-to-one correspondence with each nut 32. The positioning frame 331 is sleeved and connected with the corresponding nut 32. A connecting rod 332 is connected between every two adjacent positioning frames 331. The connecting rod 332 includes a bending section 3321 located in the middle and straight rod sections 3322 located at both ends of the bending section 3321.

[0050] Reference Figure 1 and Figure 5The bolt 31 is a flange bolt 31, and the bolt 31 includes a bolt body 311 and a bolt cap 312. The bolt cap 312 is provided with a flange-shaped flange 313 at one end close to the bolt body 311. The bolt caps 312 of each bolt 31 are commonly wound with a synchronous traction rope 34. The two ends of the synchronous traction rope 34 are connected to each other to form a ring structure. The synchronous traction rope 34 is a rubber elastic rope. When the synchronous traction rope 34 is wound and connected with each bolt cap 312, tension deformation occurs. The synchronous traction rope 34 is provided with four spiral coils 341, and each spiral coil 341 is respectively arranged in a one-to-one correspondence with each bolt cap 312. The spiral coil 341 is sleeved on the corresponding bolt cap 312, and there is friction damping between the bolt cap 312. The synchronous traction rope 34 is provided with four cable tie rings 35, and each cable tie ring 35 is respectively arranged in a one-to-one correspondence with each spiral coil 341. Both ends of the spiral coil 341 are simultaneously connected with the cable tie ring 35. The cable tie ring 35 can hinder the spiral coil 341 from unfolding, so that the staff can sleeve each spiral coil 341 on the corresponding bolt cap 312 respectively.

[0051] In the process of connecting the steel structure beam 20 and the connecting plate 1 by using the fastening assembly 3, each nut 32 on the same connecting plate 1 is positioned by a positioning piece 33, and at the same time, a synchronous traction rope 34 is commonly wound around the bolt caps 312 of each bolt 31 corresponding to the same connecting plate 1. When the staff rotates any bolt 31, the other bolts 31 of the same group can be driven to rotate at the same time. In this process, each nut 32 corresponding to the same connecting plate 1 is positioned by the positioning piece 33, so that the staff can quickly rotate each nut 32 to a state close to being locked with the nut 32, which is beneficial to improving work efficiency. When it is necessary to further tighten the bolts 31 and nuts 32 of the fastening assembly 3, the synchronous traction rope 34 is removed and each fastening assembly 3 is locked separately.

[0052] Reference Figure 2 The beam-column steel structure connecting member also includes two positioning steel rings 5, which are used to surround the steel structure column 30. The positioning steel rings 5 ​​are welded and fixed to the steel structure column. The positioning steel rings 5 ​​are provided with positioning notches 51 for avoiding the seat body 411.

[0053] The positioning notch 51 of the positioning steel bar ring 5 can form a positioning effect on the hinge seat 41, that is, the positioning steel bar forms a positioning effect on the entire beam-column steel structure connecting part, so that it is not easy to cause horizontal displacement during the welding of the auxiliary connecting plate 2 and the hinge seat 41 to the steel structure column 30.

[0054] The implementation principle of the prefabricated building beam-column steel structure connection component of the embodiment of the present application is as follows: the steel structure beam 20 is installed on the steel structure column 30 through two beam-column steel structure connectors. When there is an alignment error between two adjacent connecting plates 1, the steel structure beam 20 forces the two connecting plates 1 to be parallel to each other, so that the relative angle between the connecting plate 1 and the steel structure column 30 changes. Since the connecting plate 1 is connected to the steel structure column 30 through the hinge 4, the relative angle change between the connecting plate 1 and the steel structure column 30 can be achieved by a small angle rotation of the connecting plate 1, rather than by deformation of the connecting portion between the connecting plate 1 and the steel structure column 30, which is beneficial to reduce damage to the connecting portion between the connecting plate 1 and the steel structure column 30.

[0055] In addition to being connected to the steel structure column 30 through the hinge 4, the connecting plate 1 is also fixedly connected to the steel structure column 30 through the auxiliary connecting plate 2, so that the connection between the connecting plate 1 and the steel structure column 30 is more stable; in addition, when the relative angle between the connecting plate 1 and the steel structure column 30 changes, the arc transition portion 23 of the auxiliary connecting plate 2 can be deformed to adapt to the angle change between the transverse plate portion 21 and the longitudinal plate portion 22. Compared with the welded connection between the connecting plate 1 and the steel structure column 30 in conventional means, the arc transition portion 23 is easier to deform and is not easy to break due to stress concentration during the deformation process, so that the staff needs to overcome less resistance to lock the connecting plate 1 and the crossbeam through the fastening component 3, which is conducive to reducing the labor intensity of the staff to lock the fastening component 3. At the same time, the arc transition portion 23 is not easy to be damaged after deformation.

[0056] Example 2

[0057] Reference Figure 6 The difference between this embodiment and embodiment 1 is that: in this embodiment, two auxiliary connecting plates 2 are provided, and the two auxiliary connecting plates 2 are respectively located at two opposite sides of the connecting plate 1, and the height dimension of the auxiliary connecting plate 2 is less than or equal to half of the height dimension of the connecting plate 1, and the two auxiliary connecting plates 2 are staggered along the axial direction of the hinge shaft 42. The connecting plate 1 is connected to the steel structure column 30 through the two auxiliary connecting plates 2, which is conducive to improving the stability of the connection between the connecting plate 1 and the steel structure column 30, and makes the load of the steel structure beam 20 better transferred to the steel structure column 30. The height dimension of the auxiliary connecting plate 2 is less than or equal to half of the height dimension of the connecting plate 1, so that the two sides of the seat body 411 are exposed to the auxiliary connecting plates 2. Larger parts are provided to facilitate welding and fixing the seat body 411 to the steel structure column 30.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
