Description

Technical Field

[0001] The utility model relates to the technical field of structures, in particular to an earthquake-resistant connection node of a steel-wood hybrid structure. Background Art

[0002] Steel-wood hybrid structure is a building structure technology that uses steel and wood to complement each other. Steel has the characteristics of high strength and good tensile properties, and is suitable for structures with large spans and heavy loads. It also has excellent corrosion resistance and plasticity. Wood is lightweight, environmentally friendly, easy to process, and has good shock absorption. It is often used in architectural design to provide a warm and natural feeling. Steel-wood hybrid structure makes full use of the advantages of both materials, combining the stability of steel structure and the warmth of wood structure, and can meet the needs of buildings in terms of mechanical properties, aesthetics, and environmental friendliness.

[0003] The seismic connection nodes of steel-wood hybrid structures usually include steel plate connectors, bolts and angle steels. Steel plate connectors fix wood and steel by welding and bolting to improve overall stability. Bolts tighten the connection materials through preload and bear shear and tension. Angle steels reinforce the nodes through connecting plates and bolts to provide additional support. These components effectively transmit and disperse structural loads, ensure connection stability and strength, and improve seismic resistance.

[0004] Some connection nodes of steel-wood hybrid structures cannot be connected at active locations, which may cause the structure to become fragile and weaken its ability to adapt to changes in external forces, thus affecting durability and stability. In addition, during the installation process, some structures cannot adapt to deviated wooden piles, which may lead to installation difficulties and increase adjustment costs and man-hours. Therefore, a seismic connection node of a steel-wood hybrid structure is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a seismic-resistant connection node of a steel-wood hybrid structure, aiming to improve the connection nodes of some steel-wood hybrid structures in the prior art, which limit the movable connection and may weaken the ability to adapt to changes in external forces. At the same time, during the installation process, they cannot adapt to deviated wooden piles, which may cause installation difficulties and increase adjustment costs and working hours.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a steel-wood hybrid structure seismic connection node, including a first frame, a clamping block is arranged on the front and rear sides of the left part of the first frame, a plurality of annular holes are opened at equal intervals on the right part of the clamping block, the right part of the clamping block is fixedly connected to the left part of the first frame by a second bolt, a first screw rod passes through the right side of the front part of the first frame, a first nut is threadedly connected at both ends of the first screw rod, a second screw rod passes through the right side of the upper part of the first frame, a second nut is threadedly connected at both ends of the second screw rod, the first screw rod and the second screw rod are clamped and connected to the second frame, a square groove is opened on the left part of the second frame, and a cross block is fixedly connected to the middle side of the right part of the second frame;

[0007] As a further description of the above technical solution: a vertical wood is clamped and connected between the clamping blocks, and the front and rear sides of the vertical wood are equidistantly threadedly connected with a first bolt;

[0008] As a further description of the above technical solution: the upper and lower parts of the clamping block are fixedly connected to the limiting block;

[0009] As a further description of the above technical solution: first triangular blocks are fixedly connected to the upper and lower sides of the right part of the first frame at equal distances;

[0010] As a further description of the above technical solution: the left part of the second frame is equidistantly and fixedly connected with a second triangular block;

[0011] As a further description of the above technical solution: the cross block is clamped and connected to the crossbar, and the left part of the crossbar is equidistantly threadedly connected with a third bolt;

[0012] As a further description of the above technical solution: the left part of the limit block is close to the vertical wood;

[0013] As a further description of the above technical solution: the first screw rod and the second screw rod are close to the square groove.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, through the interaction between the first frame and the second frame and other components, the connection node is improved to be movable, so that the first screw and the second screw are indirectly crossed inside the first frame. At the same time, a square groove is opened on the left side of the second frame, and is engaged with the first screw and the second screw, leaving a certain space for the second frame to move. The movable connection can be achieved, and the ability of the structure to adapt to changes in external forces is enhanced. The connection node can freely perform a small displacement and rotation to adapt to different external forces on the structure, which helps to reduce the stress concentration of the structure and improve the durability and stability of the entire structure.

[0016] 2. In the utility model, the clamp block is provided with an annular hole through the cooperation of the clamp block and other structures; when there is a deviation in the size of the vertical wood, the second bolt is used to adjust the displacement in the annular hole to ensure the stable fixation of the clamp block. At the same time, the vertical wood is fixed by the first bolt, which can adapt to the deviation of the size of the vertical wood and ensure the fixing stability of the clamp block. Even if there is a deviation in the wood pile, it can still be effectively installed, reducing the difficulty of installation, saving adjustment costs and working hours, and ensuring the stability and safety of the final connection node.
