Description

Technical Field

[0001] This utility model relates to the field of steel truss composite beam technology, specifically a steel truss composite beam node structure. Background Technology

[0002] The node structure of a steel truss composite beam is a key part used to connect various components in a steel truss composite beam. It is usually composed of steel truss web members, connectors, and node plates. The function of the node structure is to effectively connect the steel truss web members with other components to ensure the stability and load-bearing capacity of the entire structure.

[0003] Existing node structures generally use steel. Although steel is a high-strength material, it has a certain degree of ductility. Earthquakes are a process of repeated loading. Under the frequent action of seismic motion, steel truss composite beam node structures are prone to fatigue. Under seismic action, steel will yield, which is a self-protection mechanism of the material. When the steel truss members at the node are subjected to repeated tensile, compressive and shear forces caused by earthquakes, the yielding of the steel will cause large deformation of the node, thereby reducing the service performance of the node structure. In view of the shortcomings of existing technology, we propose a steel truss composite beam node structure to solve the above problems. Utility Model Content

[0005] The reinforcing component is located on one side of the mounting component. The metal yield damper is located between the mounting component and the vertical web member and the diagonal web member, respectively. The metal yield damper provides protection for the main body of the steel truss composite beam. The connecting component connects and installs the metal yield damper with the mounting component, the vertical web member, and the diagonal web member, respectively.

[0006] Preferably, the first hinge seat is fixedly installed at the bottom of the upper chord, the top of the vertical web member is hinged inside the first hinge seat, the reinforcing assembly includes a first reinforcing plate, a second reinforcing plate, a second fixing bolt and a mounting plate, and connecting grooves are provided inside both sides of the lower chord.

[0013] This utility model discloses a steel truss composite beam node structure, which has the following beneficial effects: This steel truss composite beam node structure, by installing and supporting two sets of diagonal and vertical web members between the upper and lower chords using an umbrella-type support, and ensuring the node components are installed and connected in an umbrella-type support configuration, can improve the overall strength of the main body of the steel truss composite beam. Simultaneously, through the metal yield dampers installed between the diagonal and vertical web members and the upper and lower chords, the kinetic energy input into the structure by the earthquake can be converted into heat energy and dissipated through the yield deformation of the metal material itself. This rapidly attenuates the seismic response of the composite beam node, reduces the displacement and deformation of the node during an earthquake, prevents node damage due to excessive seismic force, and can bear some of the energy dissipation during an earthquake. This reduces the seismic force borne by the main body of the steel truss composite beam, making the stress on the main body of the steel truss composite beam more uniform during an earthquake, reducing the risk of damage to the main structure, improving the seismic performance of the entire structure, and protecting the safety and stability of the structure.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] This utility model discloses a steel truss composite beam node structure.

[0023] According to the appendix Figure 1-4As shown, the main body 1 of the steel truss composite beam is composed of an upper chord 101, a lower chord 102, vertical web members 103, and diagonal web members 104. The vertical web members 103 and diagonal web members 104 are respectively installed between the upper chord 101 and the lower chord 102, and the diagonal web members 104 are located on both sides of the vertical web members 103. Node components 2 are provided between the vertical web members 103 and the diagonal web members 104 and the upper chord 101 and the lower chord 102, respectively. The node components 2 include a reinforcing component 201, a mounting component 202, a metal yield damper 203, a first hinge seat 204, and a connecting component 205. Before use, the upper chord 101 and the lower chord 102 are sequentially installed and connected to the multiple sets of diagonal web members 104 and vertical web members 103, so that the multiple sets of diagonal web members 104 and vertical web members after installation are connected. 103 can support and connect the upper chord 101 and the lower chord 102, and can connect and support one end of the two sets of diagonal web members 104 and vertical web members 103 after installation through multiple sets of node components 2 to form a node structure. During use, the metal yield damper 203 set between the diagonal web members 104, vertical web members 103 and the upper chord 101 and lower chord 102 can consume seismic energy under seismic action, reducing the damage caused by seismic force to the node structure. At the same time, the metal yield damper 203 consumes energy by the yield deformation of the metal material during the earthquake, effectively reducing the seismic response of the node, thereby effectively protecting the node structure connected by multiple sets of diagonal web members 104 and vertical web members 103 and improving the strength of the node structure.

[0024] The reinforcing component 201 is located on one side of the mounting component 202.

The diagonal web members 104 serve as a connection, allowing the ends of the vertical web members 103 and the diagonal web members 104 to be installed and connected to the mounting base 2021 via the metal yield damper 203. The opening direction of the multiple sets of third hinge seats 2022 is consistent with the installation support direction and quantity of the two sets of diagonal web members 104 and vertical web members 103, adopting an umbrella-type support form.

It should be noted that the first reinforcing plate 2011, the second reinforcing plate 2012, the mounting seat 2021, and the lower chord 102 and the upper chord 101 can be fixed together by welding. Multiple sets of fixing bolts are first used to position the components after installation and connection. After positioning, welding is performed to improve the firmness of the installation between the components. A second reinforcing plate 2012 is installed on the inner wall of the first reinforcing plate 2011 so that the second reinforcing plate 2012 can be connected to the first reinforcing plate 2011 from the inside of the lower chord 102 and the upper chord 101. This improves the strength of the installation between the node component 2 and the main body of the steel truss composite beam 1 and avoids deformation between the node component 2 and the main body of the steel truss composite beam 1 during earthquakes.

[0026] The second reinforcing plate 2012 is fixedly installed on both sides of the inner wall of the first reinforcing plate 2011. The second reinforcing plate 2012 is inserted into the connecting groove 1021. The mounting plate 2014 is fixedly installed on both sides of the outer wall of the lower chord 102. The first reinforcing plate 2011 is attached to the outer wall of the mounting plate 2014. The second fixing bolts 2013 are all threadedly connected to the first reinforcing plate 2011 and the mounting plate 2014, and the second reinforcing plate 2012 and the lower chord 102.

[0027] The mounting assembly 202 includes a mounting base 2021, a third hinge base 2022, and a second hinge member 2023. The mounting base 2021 is fixedly installed on the inner wall of the first reinforcing plate 2011 and is fixedly connected to the lower chord 102. Multiple sets of third hinge bases 2022 are fixedly installed on the top of the mounting base 2021, and the second hinge member 2023 is hinged inside the third hinge base 2022.

[0028] The connecting assembly 205 includes a second hinge seat 2051, a first fixing bolt 2052, and a first hinge member 2053.
