Detailed Description
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.
As shown in fig. 1, the present disclosure provides a removable beam-column node of self-clinching formula, this beam-column node is mainly connected together through steel column 1 and girder steel 2 with cantilever section, connection structure mainly includes bone formula edge of a wing connecting plate 3 and web connecting plate 4, connects together the cantilever section of steel column and the edge of a wing of girder steel through bone formula edge of a wing connecting plate 3, connects together the cantilever section of steel column and the web of girder steel through web connecting plate 4.
The cantilever section of the steel column and the steel beam 2 are all made of I-shaped steel and respectively comprise a web plate and flange plates positioned on the upper side and the lower side of the web plate, the web plate connecting plates 4 are two and respectively arranged on the two sides of the cantilever section of the steel column and the web plate of the steel beam 2, and the bone type flange connecting plates 3 are also two and respectively arranged on the cantilever section of the steel column and the flange of the steel beam 2.
Further, in this embodiment, the first bolt group 13 is disposed on the bone-type flange connecting plate 3, the high-strength bolt penetrates through the bolt hole on the bone-type flange connecting plate 3 to connect the cantilever section of the steel column with the flange of the steel beam, the second bolt group 14 and the through hole are disposed at two ends of the web connecting plate in the length direction, the web connecting plate and the steel beam 2 are connected together through the second bolt group 14, and the high-strength bolt 11 penetrates through the through hole to fix the web connecting plate and the cantilever section of the steel column together.
As shown in fig. 4, the second bolt group 14 in the present embodiment is two rows of bolt holes, 8 in total, and the number of bolt groups may be determined according to the size and shape of the steel beam 2.
As described in the background art, the conventional node connection structure usually introduces a friction energy dissipation device to improve the energy dissipation capability of the node, but under the action of reciprocating load, the energy dissipation capability of the high-strength bolt is gradually reduced due to the pretensioning loss of the high-strength bolt and the abrasion of a friction plate, so in order to solve the technical problem, in this embodiment, a self-tightening device is added between the high-strength bolt 11 and the web connection plate 4, as shown in fig. 4, the self-tightening device mainly comprises an inner cam 9 and an outer cam 10 which are meshed with each other and are cylindrical, wherein the outer cam 10 is fixed on a fastener 7, the inner cam 9 is arranged on a through hole on the web connection plate, a bolt hole is arranged between the inner cam 9 and the outer cam 10, and the high-strength bolt 11 passes through the bolt holes on the two cams.
It should be noted that the inner cam and the outer cam which are engaged with each other can be understood as two cams which are engaged with each other to form a cylinder, and the surfaces of the inner cam and the outer cam which are engaged with each other are uneven, so that the inner cam and the outer cam cannot rotate relatively. Under the action of the pretension force of the high- strength bolts 11 and 12, the inner cam and the outer cam are in a tight occlusion state and do not have relative displacement; when the web plate rotates around the high-strength bolt, the inner cam and the outer cam start to rotate relatively and extrude each other along the profile surface of the cams along with the increase of the rotation angle, the rotation and the displacement of the outer cam are limited by the high-strength bolt 11 on the fastening piece, so that the rotation and the displacement between the inner cam and the outer cam are mainly the unidirectional rotation and the inward extrusion of the inner cam, the extrusion force on the inner cam is larger when the rotation angle of the web plate is larger, the friction force between the web plate and the friction plate is larger, and the extrusion force transmitted to the web plate by the cams can be controlled by controlling the radius of the cams, the push stroke motion angle (the angle rotated by the cam which runs from the lowest position to the highest position on the profile surface) and the return stroke motion angle (the angle rotated by the cam which runs from the highest position to the lowest position on the profile surface) so as to supplement the energy consumption caused by the pretension loss of the high-strength bolt and the abrasion of the The decrease in capacity is called the auto-tightening effect.
Further, as shown in fig. 5-6, the fastening member 7 in this embodiment is triangular, the fastening member 7 is welded with the outer cam 10, a bolt hole is provided at each of three ends of the triangular fastening member, and three elliptical holes are also provided in the circumferential direction around the through hole in the web connecting plate, so that the high-strength bolt 12 passes through the bolt hole in the fastening member 7 and the elliptical hole in the web connecting plate to fix the two together, thereby enabling the web connecting plate 4 to rotate at a certain angle around the high-strength bolt 11. Similarly, as shown in fig. 7-8, the inner cam 9 is welded with the web connecting plate 4, and the oval holes are arranged in the circumferential direction of the inner cam.
Further, as shown in fig. 9, in this embodiment, a left friction plate 5 and a right friction plate 6 are further respectively disposed between the web connection plate and the steel column 1 and the steel beam 2, wherein the left friction plate 5 is disposed between the web connection plate and the cantilever beam of the steel column 1, and the right friction plate 6 is disposed between the steel beam and the web connection plate.
As shown in fig. 10-11, in order to solve the problem that when the height of the cantilever section of the steel column 1 is not consistent with the height of the longitudinal section of the steel beam 2, for example, the longitudinal section of the steel beam 2 is larger than that of the cantilever section of the steel column 1, a flange plate and a web plate at the end of the steel beam may be partially cut, the remaining web plate is the same as the web plate of the cantilever section of the steel column, and bolt holes are further provided thereon, and the web plates of the two parts are connected together by a web connecting plate 4, further, a reinforced flange plate is added in the present embodiment, the flange plate is placed on the top and bottom of the web plate at the cut-out part of the end of the steel beam, the reinforced flange plate and the web plate at the end of the steel beam are connected by welding, the reinforced flange plate is also provided with through holes corresponding to the bolt holes on the flange connecting plate 3, and the flange plate 3 connects the flange on the cantilever section of the steel column and the reinforced flange on the.
It should be noted that, in this embodiment, through increasing the flange plate after strengthening, not only the height that reduces the junction realizes that two I-shaped roof beams of equidimension not are connected, and on this basis, through strengthening the processing, strengthen the bearing capacity of flange plate, prevent that its atress is too big and lead to the bolt hole on the edge of a wing to produce great residual deformation, strengthen the processing with girder steel tip flange plate simultaneously, and the flange plate overlap the thickening of welding part, consequently can be with the weak regional control of node in the power consumption region, increase the stability of whole node.
The working principle of the self-tightening type replaceable beam column node is as follows: under the action of a multi-earthquake, the structural main body and the replaceable damage element are in an elastic working stage, and the web connecting plate does not rotate relatively; under the earthquake-proof effect, the bone-type flange connecting plate on the node is partially buckled and enters an elastic-plastic deformation stage, the web connecting plate rotates to a certain degree, an inner cam on the web connecting plate starts to rotate and is extruded inwards, the self-tightening effect starts to play a role, the node mainly dissipates earthquake energy through the plastic deformation of the bone-type flange connecting plate, meanwhile, the friction between the web connecting plate and the friction plate assists in dissipating energy, other structural components are in the elastic working stage, and the structure does not need to be repaired; under the action of rare earthquake, most of the bone flange connecting plates on the nodes are subjected to yielding to enter a plastic working stage, the web connecting plates are sufficiently rotated, the cams are extruded mutually and simultaneously generate large abrasion and deformation, the self-tightening effect is reduced, high-strength bolts and bolt holes on the bone flange connecting plates are extruded mutually to generate residual deformation, the flange plates at the ends of the steel beams subjected to strengthening treatment are still in the elastic working stage, the nodes dissipate earthquake energy through the plastic deformation of the bone flange connecting plates and the friction between the web connecting plates and the friction plates, other structural components are in the elastic working stage or only a small part of structural components enter the elastic-plastic stage, and the structure can restore the use function through repairing (replacing damage elements).
