[0017] The following is a description of the preferred embodiments of the utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the utility model, and are not intended to limit the utility model.

[0018] In the description of the utility model, it should be understood that the orientation or positional relationship indicated by terms such as "left" and "right" is based on the orientation or positional relationship shown in the drawings of the specification Figure 1 shown, which is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the utility model.

[0019] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] As Figures 1 to 4 shown, this embodiment provides a joint device for a wooden structure with seismic self-resetting function, including a spring 1, a spring outer sleeve 2, a steel jacket support 3, and an anchor fixed support 4. The steel jacket support 3 is in an O shape or a square shape. In this embodiment, in order to match the shapes of the wooden cross beam and the wooden column, the steel jacket support is selected to be in an O shape. The steel jacket support 3 is sleeved on the mutually orthogonal wooden cross beam and wooden column.

[0021] As Figure 3 and Figure 4 shown, the anchor fixed support 4 includes a fixed end plate 41. The fixed end plate 41 is installed on the steel jacket support 3. The plate surface of the fixed end plate 41 is perpendicular to the axis of the steel jacket support 3. Two installation through holes are provided on the fixed end plate 41.

[0022] As Figure 1 and Figure 2 shown, wire grooves are provided at both ends of the spring 1 in the length direction. Both ends of the spring 1 in the length direction pass through the installation through holes and are installed on the fixed end plate 41 through fastening nuts. One spring 1 is respectively provided between any two adjacent and mutually orthogonal wooden cross beams and between the wooden column that is also mutually orthogonal to the two wooden cross beams. Both ends of the three springs 1 in the length direction are respectively installed on the anchor fixed supports 4 distributed orthogonally and form an equilateral triangle structure.

[0023] In addition, the spring outer sleeve 2 includes a first sleeve body 21 and a second sleeve body 22. The first sleeve body 21 and the second sleeve body 22 are sleeved on the same spring, and any one end of the two in the length direction is respectively installed on the fixed end plate 41 distributed orthogonally. Limit plates 23 are provided at the free ends of the first sleeve body 21 and the second sleeve body 22. The length dimensions of the first sleeve body 21 and the second sleeve body 22 are 1 / 2 of the static length dimension of the spring 1.

[0024] The working principle of this embodiment is further described as follows: First, fix the anchor fixed support in accordance with the design requirements and adjust the direction, and weld it in advance on the O-shaped or square-shaped steel jacket support. Then, fix the two O-shaped steel jacket supports on the wooden cross beam and the wooden column arranged orthogonally to each other respectively. Next, fix both ends of the spring in the length direction on the anchor fixed support through steel pins and fastening nuts, so that there is a spring 1 between any two adjacent and mutually orthogonal wooden cross beams and between the wooden column that is also mutually orthogonal to the two wooden cross beams. Both ends of the three springs 1 in the length direction are installed on the anchor fixed supports 4 distributed orthogonally and form an equilateral triangle structure. Finally, sleeved the spring outer sleeve on the spring and fix one end of its length direction on the anchor fixed support through steel pins and fastening nuts.

[0025] In the deformation process of this embodiment during an earthquake, when the node changes from a right angle to an obtuse angle, the spring is stretched and begins to provide a restoring tensile force; when the node changes from a right angle to an acute angle, the spring outer sleeve is compressed and begins to become a compression bar to provide a supporting pressure. At the same time, since there is a spring between any two adjacent and mutually orthogonal wooden cross beams and between the wooden column that is also mutually orthogonal to the two wooden cross beams, the equilateral triangle structure formed by the three springs is more stable, making the node have a good active earthquake resistance function. The restoring tensile force and the supporting pressure can be calculated as design parameters through the material strength and the cross-sectional area of the component.

[0026] According to the design requirements, different nodes can be arranged in multiple places, which can further improve the overall active earthquake resistance ability of the wooden structure.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
