[0002] Prefabricated buildings are made by uniformly processing various building components in factories, and then assembled on site. Various building components are fixed with connecting components to form buildings. It can greatly improve the efficiency of construction, is cost-effective, and meets the requirements of green buildings. When assembling prefabricated buildings, reliable connecting components are very important. For example, the patent with the announcement number CN 113374080 B relates to a connection assembly of a crossbeam and a structural column for an assembled building, comprising a column and a crossbeam arranged horizontally on the top of the column, wherein the crossbeam is connected to the column through a first connection part, a second connection part is arranged on one side of the top of the crossbeam, and support parts are arranged on both sides of the column; the support part comprises a connecting frame, a cylinder and a push plate, wherein the push plate is arranged horizontally at the center of the inner cavity of the connecting frame, the cylinder is installed at one end of the connecting frame, and the output end of the cylinder passes through the connecting frame and is connected to the push plate through a connecting rod; the present invention enhances the wind resistance of the assembled building through the mutual cooperation between the cylinder, the first spring, the wedge block, the second spring and the plug block, so as to avoid the roof shaking too much in windy weather or strong convective weather and damage to the beam, thereby improving the firmness and service life of the assembled building; Another example is the patent with announcement number CN 222390633 U, which relates to a node connection assembly for prefabricated buildings, including a first connection plate arranged on the side of a column, and a second connection plate located below the first connection plate, the second connection plate being provided with a detachably connected damper, a crossbeam being provided between the first connection plate and the damper and being fastened and connected by a plurality of high-strength bolts respectively; the crossbeam is provided on each side of the column to form a node of the prefabricated building; the first connection plate and the second connection plate are connected to the column respectively by high-strength bolts, and / or tension screws. The node connection assembly for prefabricated buildings improves the connection method between the column and the crossbeam, and provides the damper at the connection between the crossbeam and the column, which can effectively reduce or even prevent the plastic deformation of the crossbeam and the column body, reduce the risk of damage to the column or the crossbeam, and reduce the difficulty of maintenance of the crossbeam and the column in the later stage; However, combined with the actual assembly and use of connection components for prefabricated buildings, the current connection components still have certain disadvantages, such as: 1. The component structure that can be used for end connection and wrapping of structures such as beams, slabs, and columns has a large overall weight and occupies a large space. When used for connection, it needs to be hoisted and fixed separately, which is not conducive to rapid assembly and is not conducive to improving assembly and connection efficiency; 2. After the general connection components are assembled and used, their structural strength is not high, which is not conducive to coping with the stress changes in different directions of the building construction, and cannot improve the bending strength of the connection nodes; 3. The vibration buffering ability is poor or even cannot be used for vibration buffering. Some vibration buffering structures are complex, which is not conducive to rapid installation and use, and is not convenient for adjustment and use; 4. Generally, it can only be used for two-sided connection between beams, slabs and columns, and cannot be combined to adapt to the use of complex nodes. It is not conducive to improving the connection strength and cannot be used in different nodes.
