Technical Field
[0001] This utility model relates to the field of earthquake-resistant technology in building engineering, specifically to an earthquake-resistant buffer device for wooden beams in rural houses. Background Technology
[0002] Dampers, widely used in engineering for vibration reduction, operate primarily on the principle of energy dissipation. When a structure is subjected to external excitation forces, the damper converts some of the mechanical energy into heat or other forms of energy through the deformation or flow of its internal materials, thereby reducing the amplitude and velocity of the structure's vibration and achieving vibration reduction. Dampers come in various types, but generally utilize the inherent properties of the materials or ingenious structural design to achieve effective energy dissipation. Dampers play a vital role in engineering applications. First, in building construction, dampers can significantly improve the seismic performance of structures and reduce earthquake damage. Second, in mechanical equipment, dampers can effectively reduce the impact of vibration on equipment accuracy and lifespan, improving operational stability and reliability. Furthermore, dampers are widely used in aerospace, transportation, and other fields, providing effective solutions for vibration control problems in various complex environments.
[0003] Currently, existing dampers in the construction field are mostly used in large concrete and steel structures. These devices are large, expensive, and require professional installation. However, in the seismic reinforcement and renovation of many rural houses, traditional strengthening methods such as wire binding and nailing are still used, lacking corresponding simple and easy-to-use damping buffer devices. Therefore, a seismic buffer device for wooden beams in rural houses is needed to address these technical shortcomings. Utility Model Content

The metal damping plate 6 is made of three sets of low carbon steel spliced together.

The three sets of metal damping plates 6 are arranged at equal intervals. Low carbon steel plates 5 are welded to both sides of the metal damping plate 6.

[0024] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, metal damping plates 6 are made by splicing three sets of low carbon steel. A single piece of soft steel of a certain size is hollowed out and its diameter is reduced, so that the thickness in the middle of the cross section of the hollow part is narrowed, forming a weak zone of steel stress. This makes better use of the deformation of metal materials to consume external seismic horizontal forces. The advanced low carbon steel yield deformation energy dissipation principle is adopted. The wooden beam and the concrete structural column of the wall are reliably connected by the circular fixing ring assembly and the triangular steel support assembly to form a seismic buffer connection.
[0025] A lower semicircular ring 3 is welded to the concave arc surface of a steel rectangular connector 4. An upper semicircular ring 1 is fixedly connected to the upper part of the lower semicircular ring 3. The lower semicircular ring 3 and the upper semicircular ring 1 constitute a circular fixing ring assembly. Fastening bolts 2 are fastened to the sides of the lower semicircular ring 3 and the upper semicircular ring 1. The upper semicircular ring 1 and the lower semicircular ring 3 have the same diameter, both with a width of 120mm. The shape of the steel rectangular connector 4 matches the circular fixing ring assembly. It is hollow inside and has a size of 120mm*100mm.
[0026] Specifically, such as Figure 1 and Figure 2 As shown, the upper part of the device is equipped with a circular fixing ring assembly that connects to the wooden beams of rural houses. It is made of steel, with an upper semi-circular ring 1 and a lower semi-circular ring 3 of equal diameter forming a ring. It is fastened with a steel high-strength bolt 2, which can effectively connect the device to the wooden circular beams of the house. The horizontal stress section of the wooden beam and the vertical stress surface of the wall are connected by a metal energy dissipation section, which can buffer the movement of the wooden roof beams during an earthquake.
[0027] A connecting steel plate 7 is fixedly connected to the lower part of the metal damping plate 6. A triangular steel plate support 8 is welded to the connecting steel plate 7. A base steel plate 10 is welded to the bottom of the triangular steel plate support 8. The connecting steel plate 7, the triangular steel plate support 8 and the base steel plate 10 constitute a triangular steel support assembly. Four sets of concrete connecting bolts 9 are installed at the base steel plate 10. The base steel plate 10 uses chemical anchor bolt technology to connect and fix the concrete connecting bolts 9 to the reinforced concrete structural column. The connecting steel plate 7 and the base steel plate 10 have the same width, both 100mm. The height of the connecting steel plate 7 is 150mm and the length of the base steel plate 10 is 160mm.
[0028] Specifically, such as Figure 1 As shown, the lower part of the device is equipped with a steel fixed triangular support assembly that is connected to the concrete structural column of the rural house reinforcement. It mainly consists of a connecting steel plate 7, a triangular steel plate support 8 and a base steel plate 10. Chemical anchor bolt technology is used to firmly fix two pairs of concrete connecting bolts 9 to the reinforced concrete structural column.
[0029] Working Principle: The device consists of three main parts: a circular fixed ring assembly, a metal damping plate assembly (6 components), and a triangular steel support assembly. The metal damping plate assembly (6 components) is the core of the device. It is made by splicing three sets of low-carbon steel to form the metal damping plate (6). A single piece of soft steel of a certain size is hollowed out and its diameter is reduced, making the thickness of the cross-section in the hollowed-out part narrower, forming a weak zone in the steel's stress. The lower part of the device is equipped with a steel fixed triangular support assembly connected to the concrete structural column used for rural house reinforcement. This assembly mainly consists of a connecting steel plate (7), a triangular steel plate support (8), and a base steel plate (10). Chemical anchor bolt technology is used to firmly fix two pairs of concrete connecting bolts (9) to the reinforced concrete structural column. After all the nuts are tightened, it ensures stability and prevents slippage under seismic stress. The device is equipped with a circular fixing ring assembly for connecting to the wooden beams of rural houses. Made of steel, the upper and lower semicircular rings 1 and 3, with equal diameters, form a ring. These are secured to high-strength steel bolts with fastening bolts 2, effectively connecting the device to the wooden circular beams of the house. The horizontal load-bearing section of the wooden beam and the vertical load-bearing surface of the wall are connected by a metal energy dissipation section, which can buffer the movement of the wooden roof beams during earthquakes. From a structural mechanical performance perspective, it also meets the practical requirements for earthquake resistance in rural houses. Utilizing the advanced low-carbon steel yield deformation energy dissipation principle, the circular fixing ring assembly and triangular steel support assembly reliably connect the wooden beams to the concrete structural columns of the walls, forming an earthquake-resistant buffer connection. This effectively avoids damage to the wooden beam connections of rural houses caused by seismic forces, reducing losses from disasters.
