Detailed Description
The invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, the invention is an energy-consuming sparrow for reinforcing a wood beam-column connection node, which comprises a wood column 1, a wood beam 2, a sparrow 7 and an energy-consuming device; the wood column 1 and the wood beam 2 are connected through mortise and tenon joints, the energy dissipation device is fixed at a node between the wood column 1 and the wood beam 2, and the sparrow 7 is installed on the energy dissipation device. The inclination angle of the bevel edge of the sparrow 7 is consistent with the inclination degree of the connecting piece in the energy consumption device.
As shown in fig. 3, the column steel anchor ear 3 and the beam steel anchor ear 4 are fixed by bolts with symmetrical sides, and the two are fixed on the corresponding beam and column. The energy dissipation device is formed by overlapping and reinforcing three beam connecting sheets 5 extending from the beam steel anchor ear 4 and a column connecting sheet 6 extending from the column steel anchor ear 3.
As shown in fig. 4, bolt holes 11 are preset in the beam connecting pieces 5 at two sides extending from the beam steel anchor ear 4; the middle column connecting sheet 6 extended from the column steel hoop 3 is provided with a bolt moving hole 10, and two friction sheet grooves 9 are respectively arranged on two sides of the column connecting sheet 6 and can be embedded with friction sheets 8. The center of a preset bolt hole of a beam connecting sheet 5 extending from the beam steel anchor ear 4 corresponds to the center of a preset bolt moving hole groove 10 of a column connecting sheet extending from the column steel anchor ear 3. The diameter of a bolt hole 11 formed in the beam connecting piece 5 is larger than that of a bolt 12, steel gaskets 13 and nuts 14 are arranged on two sides of the bolt 12, and the nuts 14 are tightened to generate pre-pressure. The pressure between the energy consuming devices is provided by the prestressed bolts 12.
When the beam-column type wood member is acted by external force, when the external force effect exceeds the maximum static friction force between the connecting sheets and the friction sheets on two sides in the energy dissipation structure, the wood beam 2 rotates relative to the wood column 1 to drive the beam steel hoop 4, the beam connecting sheet 5 extending from the beam-column type wood member rotates relative to the column connecting sheet 6 extending from the column steel hoop 3, and the bolt 12 in the energy dissipation device can displace in the direction of the bolt moving hole 10. At this time, the connecting piece and the embedded friction plate 8 consume energy because the two slide relatively to generate sliding friction force; in the process that the bolt 12 can move in the bolt moving hole 10, the pressure between the connecting sheets is provided by the anchoring of the bolt 12, and at the moment, because the nut 14 and the gasket 13 which play a role in fixing in the energy consumption device extrude the connecting sheets, the connecting sheets are combined more tightly, the sliding friction force is increased, and the energy consumption function can be fully played in the structure.
As shown in fig. 4, during the movement of the bolt, the friction force generated between the connecting plate and the friction plate 8 can dissipate the energy transmitted from the outside by the friction force.
