Description

Technical Field

[0001] The invention relates to the technical field of prefabricated buildings, and in particular to a beam-column stress node of a prefabricated beam structure with recoverable functions. Background Art

[0002] At present, although prefabricated buildings have shown their unique advantages in the modernization process of the construction industry, especially through standardized design, factory production and assembly construction, they have greatly improved construction efficiency, shortened construction period, and to a certain extent achieved resource conservation and environmental protection. This construction method enables components to be precisely manufactured in the factory and then transported to the construction site for rapid assembly, thereby greatly improving the construction speed and quality control level of the building.

[0003] However, although prefabricated buildings have made remarkable achievements in conventional construction, their current technical system still faces certain challenges when facing natural disasters, especially emergencies such as earthquakes. Specifically, although prefabricated buildings can realize the assembly production of components and ensure the stability and durability of buildings in daily use, after extreme natural disasters such as earthquakes, prefabricated buildings have certain limitations in the rapid repair of damaged buildings. This is mainly because although the components of prefabricated buildings are standardized, the connection method between the components and the resilient design of the overall structure may not be as flexible and resilient as traditional buildings when dealing with complex and changeable natural disasters such as earthquakes. In addition, rapid post-earthquake repair requires efficient component replacement and reassembly technology, and the current technical reserves and emergency response mechanisms of prefabricated buildings in this regard are still imperfect, resulting in difficulty in quickly restoring the use function of the building after an earthquake.

[0009] Furthermore, as a preferred embodiment of the present invention, a plurality of cantilever beam sections distributed in a ring shape are fixedly connected to one side of the annular partition, and one side of the cantilever beam section is fixedly connected to the second round steel pipe column.

[0010] Furthermore, as a preferred embodiment of the present invention, a reinforcement piece is fixedly connected to one side of the connecting plate, and the reinforcement piece is in a triangular shape.

[0011] Furthermore, as a preferred embodiment of the present invention, one side of the round steel pipe column one is fixedly connected to a support plate, the inner cavity of the support plate is provided with a fixing bolt two, one end of the fixing bolt two penetrates into the inner cavity of the web, and one side of the fixing bolt two is in contact with the support plate.

[0016] In the present invention, a method for using a beam-column stress node of a prefabricated beam structure with restorable function comprises the following steps:

[0017] Step 1: Use round steel pipe column 1 as the central support, and cooperate with two round steel pipe columns 2 to form a stable support to enhance the stability of the overall structure. Through the cooperation of the connecting plate and the fixing bolt 1, the web and the flange connecting plate are firmly connected together to form an integral structure, ensuring that the structure can withstand large loads in both vertical and horizontal directions. Strengthen the treatment of the connection between the web and the flange connecting plate to improve its stability and carrying capacity; and add a shaped plate between the flange connecting plates to enhance the cross-sectional stiffness between each flange connecting plate and improve the bending resistance of the overall structure.

By rotating the operating block, the bidirectional threaded rod is driven to rotate, thereby driving the two threaded blocks to move relative to each other under the action of the thread. The movement of the threaded block will drive the movable plate 1 and the movable plate 2 to move and rotate until the clamping block is in close contact with the rotating shaft to achieve the positioning of the rotating shaft. During the movement of the movable plate 1 and the movable plate 2, the linkage plate 2 will drive the round block to move in the inner cavity of the linkage plate 1 to ensure that the seismic assembly can respond flexibly when subjected to vibration. When vibration occurs, rotation will occur between the round steel pipe column 1 and the web. Under the action of the seismic assembly, the web is repositioned to ensure that the round steel pipe column 1 and the round steel pipe column 2 components remain elastic and are not damaged, so as to achieve rapid post-earthquake repair of the node.

[0019] Beneficial effects: The technical solution of the present application has the following technical effects: The present invention has the advantages of improving ductility and rotation capacity and enhancing connection strength. First, a gap is set between the round steel pipe column 1 and the web, which not only improves the ductility of the node, so that the structure can more effectively absorb and disperse energy when subjected to force, but also enhances the rotation capacity of the node. By avoiding direct extrusion and collision between the round steel pipe column 1 and the web, the risk of damage to the structure under dynamic loads such as earthquakes is reduced, thereby improving the durability and safety of the overall structure. Furthermore, advanced seismic-resistant components are introduced in the round steel pipe column 1, the round steel pipe column 2, the web and the flange connection plate, etc. The main components play a vital role in ensuring that these main components can maintain elasticity and not suffer plastic failure under extreme conditions such as earthquakes, so that the structure can quickly restore its original bearing capacity and stability after the earthquake, providing a strong guarantee for the rapid post-earthquake repair of the nodes; finally, by adopting connecting plates and fixing bolts, the connection strength between the web and flange connecting plates is effectively improved, thereby increasing the initial stiffness and ultimate bearing capacity of the circular steel pipe column and the web, which not only improves the stability and safety of the overall structure, but also increases the yield load of the node, so that the structure can function more reliably when subjected to stress.
