Abstract
Description
Technical Field
[0001] The utility model relates to the field of beam-column nodes, in particular to a novel steel tube concrete beam-column cross node connector. Background Art
[0002] At present, due to the good mechanical properties of steel tube concrete columns, on the one hand, the steel tube can impose lateral constraints on the compressed concrete, so that the concrete in the tube is in a three-dimensional compressive stress state; on the other hand, with the support of the inner filling concrete, the stability of the steel tube wall is enhanced and the instability mode of the steel tube is changed. The combination of the two greatly improves the bearing capacity and ductility, especially in high-rise buildings. The compressive and shear bearing capacity of steel tube concrete columns is more obvious than that of ordinary reinforced concrete. Although the compressive bearing capacity is slightly lower than that of steel columns, there is no local instability problem. In addition, the plasticity of steel tube concrete is good, which prevents the brittle failure of the concrete in the tube, and the axial compression ratio can be unlimited in high-rise buildings.
[0003] The defects of circular steel tube concrete columns also make it have many limitations, such as the arc surface of the circular steel tube, which makes welding inconvenient and the node connection processing is complicated. The effective connection of the node is the basic guarantee of structural safety. Conventional beam-column nodes are mostly constructed by welding technology, and the node structure is complex, which makes on-site construction operation inconvenient and affects the construction quality and progress. Utility Model Content
[0004] The utility model aims to provide a novel steel tube concrete beam-column cross node connector to solve the problem of complicated construction operation of conventional beam-column nodes proposed in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of steel tube concrete beam-column intersection node connector, comprising a circular tube, an I-beam and a sleeve fixedly sleeved on the side wall of the circular tube, a pair of circular rings fixedly installed on the side wall of the sleeve, the circular rings form a connecting portion on the circumferential side of the main body in a manner that can contact the I-beam, the connecting portion and the I-beam are fixedly connected by fasteners, a pair of the circular rings are fixedly installed with the same reinforcing plate between adjacent I-beams, and both ends of the reinforcing plate extend to be fixedly connected to the side walls of the I-beams respectively.
[0006] Preferably, a plurality of reinforcing ribs distributed in a circumferential manner are fixedly mounted on the side wall of the sleeve, and a pair of grooves for accommodating the circular ring are formed on one side of the reinforcing ribs.
[0007] Preferably, a trapezoidal groove for accommodating the reinforcement plate is provided at the central position of the reinforcement rib.
[0008] Preferably, the reinforcing plate forms bent sections at the left and right ends of the main body in a manner that the reinforcing plate can contact the side walls of the I-beam, and the top and bottom of the reinforcing plate are bent to form mounting ears, and the mounting ears extend to contact the circular ring.
[0009] Preferably, the fasteners are a pair of channel steels installed on the side walls of the I-beam and a plurality of high-strength bolts provided with nuts and washers.
[0010] Preferably, the corner connections of the reinforcing plate are all rounded for smooth transition.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] The utility model fastens the circular tube and the I-beam through the cooperation of the sleeve, the circular ring, the reinforcing rib, the reinforcing plate and the fasteners. When encountering a large earthquake vibration disaster, the seismic resistance of the concrete beam and column at the connection node structure position can be increased, and the deformation of the I-beam can be reduced or avoided, thereby avoiding the failure of the connection node structure due to the structure of the beam and column itself. The utility model has a simple structure and is easy to operate. It only needs to assemble and connect the I-beam and the reinforcing plate, which effectively improves the assembly efficiency.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-Figure 6 The utility model provides a technical solution: a new type of steel tube concrete beam-column intersection node connector, comprising a round tube 1, an I-beam 2 and a sleeve 3 fixedly sleeved on the side wall of the round tube 1, the sleeve 3 is welded and fixed to the outer surface of the round tube 1, a pair of circular rings 4 are fixedly installed on the side wall of the sleeve 3, a plurality of circumferentially distributed reinforcing ribs 5 are fixedly installed on the side wall of the sleeve 3, a pair of grooves for accommodating the circular rings 4 are opened on one side of the reinforcing rib 5, and the reinforcing rib 5 forms a triangular structure at the connection between the sleeve 3 and the circular ring 4. The circumferentially arranged reinforcing ribs 5 effectively increase the stiffness of the node. The connection strength is that the ring 4 forms a connecting portion 8 on the circumferential side of the main body in a manner that it can contact the I-beam 2. The connecting portion 8 is fixedly connected to the I-beam 2 by fasteners. The fasteners are a pair of channel steels 6 installed on the side walls of the I-beam 2 and a number of high-strength bolts with nuts and washers. The above is the prior art and will not be repeated here. A pair of rings 4 are fixedly installed with the same reinforcing plate 7 between adjacent I-beams 2. The corner connections of the reinforcing plate 7 are all chamfered and smoothly transitioned. The advantage of this arrangement is that it avoids scratching the skin due to sharp corners during installation. The two ends of the reinforcing plate 7 are divided into The reinforcing rib 5 is provided at the central position of the reinforcing rib 5 with a trapezoidal groove for accommodating the reinforcing plate 7, providing installation space for the reinforcing plate 7, and the reinforcing plate 7 is formed with a bending section 9 at the left and right ends of the main body in a manner that can contact the side wall of the I-beam 2. The bending section 9 is in contact with the channel steel 6 of the fastener. The top and bottom of the reinforcing plate 7 are both bent to form mounting ears 10, and the mounting ears 10 extend to contact with the circular ring 4 and are fastened by bolts. The present application cooperates with the sleeve 3, the circular ring 4, the reinforcing rib 5, the reinforcing plate 7 and the fastener to form a circular tube 1, an I-beam 2. The steel 2 is tightly connected, and the reinforcing plate 7 effectively strengthens the connection strength between a pair of circular rings 4 and an adjacent pair of I-beams 2. When encountering a large earthquake vibration disaster, the seismic resistance of the concrete beam-column at the connection node structure position can be increased, and the deformation of the I-beam 2 can be reduced or avoided, thereby avoiding the failure of the connection node structure due to the beam-column structure itself. The structure is simple and the operation is convenient. During assembly, only the I-beam 2 and the reinforcing plate 7 need to be assembled and connected. The abutting parts of the circular tube 1, the sleeve 3, the circular ring 4 and the reinforcing rib 5 can be welded at the construction site, and other components can be prefabricated, which effectively improves the assembly efficiency.
