Description
Technical Field
The utility model belongs to the technical field of steel structures, and particularly relates to a novel weakened section steel connecting beam.
Background
The steel coupling beam is combined with the traditional steel plate shear wall structure, and a coupled steel plate shear wall structure system can be formed. The connected steel plate shear wall structure is relatively flexible in arrangement, a door and window opening is convenient to open, and the requirements of a structural system on the bending resistance bearing capacity and rigidity of the frame column can be reduced. In the coupled steel plate shear wall structure, the best failure mode is that the steel coupling beam is used as the first seismic fortification. Under the action of small and medium earthquakes, the steel connecting beam can be damaged preferentially to protect other structural components, and the steel connecting beam is designed into a replaceable component, so that better economical efficiency and earthquake-resistant performance are easy to obtain, however, the existing steel connecting beam structure cannot well solve the problem.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems in the prior art, the utility model provides a novel weakened steel connecting beam to realize the idea that the steel connecting beam in the coupled steel plate shear wall is used as a replaceable component and the first earthquake-proof fortification is realized, so that the coupled steel plate shear wall obtains better economical efficiency and earthquake-proof performance.
In order to achieve the purpose, the utility model provides the following technical scheme:
the utility model relates to a novel weakened section steel connecting beam which comprises an I-shaped steel and end plates vertically welded at two ends of the I-shaped steel; the I-shaped steel comprises flange plates and web plates; two ends of each side of the flange plate are respectively provided with a node; a central hole is formed in the center of the web plate; a plurality of bolt holes are formed in the end plate.
Furthermore, a stiffening rib is welded between the outer side of the flange plate and the end plate.
Further, the central hole is of a hyperbolic quadrilateral hole type.
Further, the node is a dog-bone node.
Compared with the prior art, the novel weakened steel connecting beam has the advantages that the web plate and the flange plate of the I-shaped steel of the steel connecting beam are weakened, so that plastic hinge can be easily formed on the steel connecting beam firstly, the steel connecting beam is positioned in the first earthquake proofing, and energy consumption is preferentially carried out; in addition, the steel coupling beam is connected with the coupled steel plate shear wall through an end plate and a bolt so as to realize the replaceability of the steel coupling beam; stiffening ribs are welded at the flange plate-to-end plate weld to strengthen the end plate-to-flange plate connection, since the weld is prone to tearing at the end plate-to-flange plate weld. In addition, the web plate is weakened by arranging the hyperbolic quadrilateral holes, and among the plurality of hole patterns, the hyperbolic quadrilateral hole patterns have the best energy consumption and can better meet the requirement of hole forming on buildings; the steel coupling beam is designed as a dog bone beam end so that a plastic hinge is easily formed at the dog bone node, not the beam end. Therefore, the steel connecting beam web and the flange plate are weakened, so that the steel connecting beam is preferentially taken as first earthquake proofing under the action of medium and small earthquakes and is easy to replace, other structural members are protected, and better economical efficiency and earthquake resistance can be obtained.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-3, the novel weakened section steel coupling beam of the present invention includes an i-beam 1 and end plates 2 vertically welded to two ends of the i-beam 1; the I-shaped steel 1 comprises flange plates 11 and web plates 12; two ends of each side of the flange plate 11 are respectively provided with a node 14; a central hole 13 is formed in the center of the web 12; and a plurality of bolt holes 21 are formed in the end plate 2 and used for combining the steel coupling beam with the steel plate shear wall. In the embodiment, a stiffening rib 3 is welded between the outer side of the flange plate 11 and the end plate 2; the central hole 13 is a hyperbolic quadrilateral hole; the node 14 is a dog-bone node.
In the embodiment, the web plate 12 and the flange plate 11 of the I-steel 1 of the steel connecting beam are weakened, so that plastic hinge can be easily formed on the steel connecting beam firstly, the steel connecting beam is positioned in the first path of earthquake proofing, and energy consumption is preferentially consumed; in addition, the steel coupling beam is connected with the coupled steel plate shear wall through the end plate 2 and the bolts 21 so as to realize the replaceability of the steel coupling beam; as the weld is prone to tearing at the end plate 2 to flange plate 11 weld, stiffening ribs 3 are welded at the flange plate-end plate weld to strengthen the end plate to flange plate connection. In addition, a central hole of a hyperbolic quadrilateral is formed in the web 12 to weaken the web, and among a plurality of hole types, the hyperbolic quadrilateral hole type has the best energy consumption and can better meet the requirement of hole opening on buildings; the steel coupling beam is designed to be a dog-bone beam end (i.e., the arrangement of the nodes 14) so that a plastic hinge is easily formed at the dog-bone node, rather than the beam end. Therefore, the steel connecting beam web and the flange plate are weakened, so that the steel connecting beam is preferentially taken as first earthquake proofing under the action of medium and small earthquakes and is easy to replace, other structural members are protected, and better economical efficiency and earthquake resistance can be obtained.
