Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building connection structure technology, specifically relating to a snap-fit steel-wood composite node with shock absorption and energy dissipation function. Background Technology
[0002] Against the backdrop of the steady progress towards the "dual carbon" goals, steel-wood hybrid structures are gradually becoming a new favorite in the construction industry due to their unique advantages. They possess the high strength and load-bearing capacity of steel structures, meeting the stringent structural stability requirements of various buildings; and the green, environmentally friendly, and renewable characteristics of wood structures, highly aligning with the current concept of sustainable development. For this reason, steel-wood hybrid structures have been widely and deeply applied in various fields such as prefabricated buildings, tourist accommodations, and rural revitalization projects.
[0003] However, in the promotion of steel-wood hybrid structures, connection node technology has become a bottleneck that cannot be ignored. Traditional connection methods struggle to achieve a balance between the three requirements of "construction efficiency, connection performance, and green and low-carbon development," severely hindering the progress of the entire industry.
[0004] As the modern construction industry accelerates its transformation towards environmental protection and energy conservation, wood, as a lightweight, low-energy-consumption, and environmentally friendly building material, is becoming increasingly important and is gradually becoming an ideal alternative to traditional concrete and steel, possessing extremely high research value and application potential. Compared with concrete and steel structures, wood structures can significantly reduce carbon emissions during construction, contributing to the achievement of "dual carbon" goals. At the same time, the unique connection methods and material properties of wood structures also enable faster construction, effectively shortening the construction period and reducing construction costs.
[0005] However, current technologies have many shortcomings, which seriously affect the further development of steel-wood hybrid structures. Traditional bolted connections require on-site drilling and positioning, which are extremely cumbersome procedures. This not only consumes a lot of manpower and resources but also greatly extends the construction period, making it difficult to meet the demands of modern buildings for efficient construction.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a snap-fit steel-wood composite node with shock absorption and energy dissipation function, comprising H-shaped steel columns, wooden beams, upper steel structural members, lower steel structural members, and connecting members;
[0007] The H-shaped steel column passes through the upper steel structure and the lower steel structure in sequence. Both the upper and lower steel structures have outwardly extending cross-shaped sides. A wooden beam is installed between each opposite side of the upper and lower steel structures.
[0008] At least one side of the lower steel structure is movably connected to one end of the connector, and the other end of the connector is fixedly connected to the H-shaped steel column.
[0009] Preferably, the upper steel structural member and the lower steel structural member have grooves on their opposite surfaces for connecting the wooden beam.
[0010] Preferably, there are an even number of connectors; wherein, one end of two connectors is slidably connected to both sides of the lower end of one side of the lower steel structure member, and the other end is fixedly connected to both sides of the corresponding H-shaped steel column.
[0011] Preferably, each of the connecting members includes: a sliding body, a hinge member, and a fixed body, wherein the two ends of the hinge member are respectively hinged to the sliding body and the fixed body;
[0012] The sliding body is slidably connected to the lower end of the edge of the lower steel structure member;
[0013] The fixing body is fixedly connected to the H-shaped steel column.
[0014] Preferably, each side of the upper steel structural member and the lower steel structural member is provided with multiple holes, and the multiple holes are used to connect the upper steel structural member and the lower steel structural member by means of bolt assembly.
[0015] Preferably, each side of the upper and lower steel structural members has a damping hole for connecting the damper at the middle position.
[0016] The beneficial effects of this utility model are as follows: First, it enables rapid connection of steel columns and wooden beams, eliminating the cumbersome on-site drilling and welding processes of traditional connection methods, greatly shortening construction time and improving construction efficiency. Second, through the synergistic effect of prestressed support connectors and replaceable threaded dampers, this combined node possesses both the strong load-bearing capacity and stiffness of prestressed support connectors and the energy dissipation and vibration reduction effect of dampers. It can resist certain deformation and energy dissipation under load, making the structure of this utility model safer and more reliable when encountering sudden loads such as earthquakes. Third, the node has high flexibility; the connection method between components facilitates disassembly and replacement, which not only benefits later maintenance and modification but also enables material reuse, conforming to the concept of green and environmentally friendly development.

[0026] The specific embodiments of the present invention will now be described in full with reference to the accompanying drawings. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details are not intended to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.
[0027] like Figure 1-9 As shown, this utility model discloses a snap-fit steel-wood composite node with shock absorption and energy dissipation function, consisting of H-shaped steel column 1, wooden beam 2, upper steel structure component 3, lower steel structure component 4, and connector 5;
[0028] The H-shaped steel column 1 passes through the upper steel structure 3 and the lower steel structure 4 in sequence. Both the upper steel structure 3 and the lower steel structure 4 have outwardly extending cross-shaped sides. A wooden beam 2 is installed between each opposite side of the upper steel structure 3 and the lower steel structure 4.
[0029] At least one side of the lower steel structural member 4 is movably connected to one end of the connector 5, and the other end of the connector 5 is fixedly connected to the H-shaped steel column 1.
[0030] Furthermore, the upper steel structural member 3 and the lower steel structural member 4 each have grooves 6 on their opposite surfaces for connecting the wooden beam 2.
[0031] Furthermore, there are an even number of connectors 5; wherein, one end of two connectors 5 is slidably connected to both sides of the lower end of one side of the lower steel structure member 4, and the other end is fixedly connected to both sides of the corresponding H-shaped steel column 1.
[0032] Furthermore, each of the connecting members 5 includes: a sliding body 501, a hinge 502, and a fixing body 503, wherein the two ends of the hinge 502 are respectively hinged to the sliding body 501 and the fixing body 503;
[0033] The sliding body 501 is slidably connected to the lower end of the side of the lower steel structure member 4;
[0034] The fixing body 503 is fixedly connected to the H-shaped steel column 1.
[0035] Furthermore, each side of the upper steel structural member 3 and the lower steel structural member 4 is provided with a plurality of holes 301, which are used to connect the upper steel structural member 3 and the lower steel structural member 4 by means of bolt assemblies.
[0036] As mentioned above, a certain number of threaded holes 101 (a total of 6, evenly distributed on both flanges) are opened on the H-shaped steel column 1 for connection with the lower steel structural member 4. The lower steel structural member 4 has holes opened at corresponding positions.
[0037] Furthermore, each side of the upper steel structural member 3 and the lower steel structural member 4 is provided with a damping hole 302 for connecting the damper 7.
[0038] The node structure of this utility model incorporates a damper 7. The upper steel structural member 3 and the lower steel structural member 4 effectively clamp the wooden beam 2. Simultaneously, under sudden or impact loads (such as earthquakes), the wooden beam 2 can undergo a certain vertical displacement within the allowable range of the damper 7 to dissipate the energy of sudden or impact loads such as earthquakes, thereby reducing the damage and destruction of the connection node between the wooden beam and the H-shaped steel column 1 caused by sudden or impact loads such as earthquakes. This node structure possesses recoverable and resistant properties, thus achieving superelasticity.
[0039] This utility model allows for perforation at the ends of the wooden beam 2, as well as perforation at corresponding positions of the upper steel structural member 3 and the lower steel structural member 4, to facilitate connection between the wooden beam and the H-shaped steel column 1.
