Description
Technical Field
The utility model relates to the field of buildings, in particular to a connecting node on a prefabricated external wall panel, which comprises a shearing device easy to replace.
Background
The assembled steel structure building is a novel structure which is developed quickly at present, and has the advantages of high construction speed, low manufacturing cost, attractive appearance and the like. The steel structure building can realize the on-site dry operation, reduces the environmental pollution, and the material can be recycled, accords with the environmental protection policy advocated by the state, and has good application prospect in the residential market. In addition, the vigorous development of steel structure buildings is an effective way for resolving the surplus of steel productivity in China.
The connection node of the external wall panel and the steel frame is taken as the design key point of the assembled steel structure building, and has considerable influence on the seismic performance of the building (Dian Erlin, Marlin, Liu Xue Chun, Jiang Ji. finite element analysis on the stress performance of the assembled external wall panel steel frame [ J ]. study on building structure, 2016,37(S1): 152-. At present, the node type of the externally-hung wall board and the frame structure which are widely applied in the market is mainly a rigid connection node, but the frame beam in the main body structure and the externally-hung wall board are tightly and rigidly connected when the externally-hung wall board and the frame structure are connected, so that the overall rigidity is high, and the structure is easy to damage when the structure is subjected to rare earthquake load (Wangzi Yang, the earthquake resistance research of the PC coupled shear wall structure containing the damping externally-hung wall board [ D ]. Hefei Industrial university, 2018.).
In the existing related researches on anti-Seismic energy consumption, the main energy consumption modes include the crawler-type deformation energy consumption of a U-Shaped damper (Qing Jiang, Hanqin Wang, Yuleng Feng, Xun Chong, Junqi Huang, and Yibo Liu. (2020). Enhanng the semi Performance of the compressed RC Frames with clamping coils through Setting U-Shaped Dampers and locking coils.shock and Vibration 2020.) and the energy consumption mode of plastic deformation of a shear-resistant steel piece under the shearing action (Chan RWK, Albermani F. (2008). Example deformation of shear for applying energy transmission 30: 1058). In order to better solve the problem of energy dissipation of the connection node under the action of earthquake load, the utility model combines the two energy consumption modes and provides the prefabricated external wall panel upper connection node with the easily replaceable shearing device, wherein the easily replaceable shearing device is provided with the shearing sheet made of low-yield steel. The energy consumption sequence is carried out in three stages: in the normal use stage, the connecting node can be regarded as a rigid connecting node, and energy generated by wind load and other variable loads is jointly borne by the whole body formed by the external wall panel and the structural steel frame; when the structure is in a stage of encountering a frequent earthquake or fortifying an earthquake, the shearing steel sheets in the easily-replaced shearing device are made of low-yield steel, so that energy generated by the earthquake at the stage is firstly mainly absorbed by the shearing steel sheets in the nodes in a shearing deformation energy-consuming manner; in the stage of rare earthquake, after the shearing steel sheet in the easily-replaced shearing device is sheared and damaged, the energy generated by the earthquake is absorbed by the steel plate through crawler-type deformation and energy consumption.
In addition, aiming at the problems of difficult installation and difficult maintenance and replacement after the joint is damaged commonly existing in the connecting joint of the external wall panel of the prior assembly structure, the upper connecting joint provided by the utility model also has the function of flexible disassembly. After the node is subjected to the action of a frequent earthquake and a fortification earthquake, the shearing device is easy to replace and can be detached at any time, and the shearing sheets in the shearing device are replaced, so that the service life of the node is prolonged. Meanwhile, in the dismounting and replacing process of the shearing device, the joint main body formed by the U-shaped steel plate and the angle steel connecting piece arbitrarily maintains the connection relation between the external wall-hung plate and the frame beam, the wall plate does not need to be dismounted, and the dismounting and replacing function has higher practical value for the steel structure building.

Against the background, the utility model provides a connecting node on a prefabricated external wall panel with an easily-replaceable shearing device, which aims to solve the problems that the connecting part of an external wall panel and a frame beam in an assembled steel structure building is easily damaged by rarely-occurred earthquake action and is difficult to disassemble, replace and maintain after the action of frequently-occurred earthquake.
The utility model is realized by at least one of the following technical schemes.

preferably, the two sides of the L-shaped steel plate are connected with ribbed plates for improving the structural rigidity.
Preferably, the easily replaceable shearing device comprises a first convex steel grooved plate, a shearing steel plate and a second convex steel grooved plate;
the first convex steel plate with the groove is connected with the second convex steel plate with the groove through a replaceable shearing steel sheet;
preferably, the first convex grooved steel plate is connected with the node body; the length of the steel plate of the protruding part of the second convex steel plate with the groove is the same as the distance between the two U-shaped steel plates in the node main body, the protruding part of the second convex steel plate with the groove is embedded between the two U-shaped steel plates on one side of the angle-free connecting piece, and the second convex steel plate with the groove is connected with the node main body.

Under the action of frequent earthquakes, the displacement between the structural layers is slightly increased, and energy consumption can be carried out through shearing deformation of a shearing steel sheet made of low-yield steel, so that the influence of the displacement between the layers on the whole frame is reduced. Under the action of large shock, the U-shaped steel plate starts to perform reciprocating crawler-type displacement due to the fact that displacement between structural layers is increased, the shearing steel sheet made of low-yield steel yields and destroys before the U-shaped steel plate, and after the shearing steel sheet quits working, node energy consumption is performed by crawler-type deformation of the U-shaped steel plate. Compared with a pure rigid connection node, the three-stage working mode allows relative displacement to occur between the external wall-hanging plate and the steel frame, and can avoid damage to the connection part of the wall plate and the frame.
2. After the connection node provided by the utility model encounters frequent earthquake action, the shearing steel sheet with yield failure in the connection node can be replaced by independently replacing the easily replaced shearing device in the node. Compared with other energy consumption type nodes, the mode of connecting the easily-replaceable shearing device in the node with the node main body, the mode of connecting the frame with the node main body and the mode of prefabricating the external wall panel are mutually independent, so that when the easily-replaceable shearing device is disassembled, the whole node does not need to be disassembled, namely, the node main body, the frame and the prefabricated external wall panel are still in a connected state in the whole process of disassembling and replacing the shearing device, and convenience is provided for the installation, disassembly and maintenance of the node in the practical engineering application.
3. The connecting node provided by the utility model has a staged energy consumption mode and a flexible and detachable function, so that the energy generated by load can be prevented from being completely absorbed by the U-shaped steel plate of the node main body, and the node shearing steel plate can be replaced and maintained after the node shearing steel plate is withdrawn from working, and the service life of the node is prolonged to a great extent.
