Description

Technical Field

[0001] The utility model belongs to the technical field of concrete wall assembly, and in particular relates to an energy dissipation structure of a combined mild steel damper. Background Art

[0002] At present, under the action of earthquakes, the shear wall structures in actual projects have suffered serious damage in the bottom area of ​​the shear wall. Although the shear wall structure will not collapse as a whole, post-earthquake repair work is difficult to carry out, affecting people's normal production and life.

[0003] After studying the data from seismic wave experiments, we learned that the damage area of ​​the shear wall under the action of an earthquake is concentrated at the toe and base of the wall. Most of the existing energy dissipation structures use the web plate to buffer and absorb energy, and install multiple sets of web plates to enhance the energy absorption effect. Although this combination can reduce the external force impact of the shear wall, the web plates are all one-piece molded plates and cannot meet the energy dissipation requirements of shear walls of different thicknesses. Secondly, an additional layer of energy absorption plate is set between the energy dissipation structure and the shear wall to improve the situation where the structural strength is weakened due to the web plate stress.

[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1

[0027] Reference Figure 1-2 , is the first embodiment of the utility model, which provides an energy dissipation structure of a combined mild steel damper, including:

[0028] A wall 100, an energy dissipation member 200 is fixedly connected to the inner side of the wall 100, and the energy dissipation member 200 includes a base plate 203 fixedly connected to the inner side of the wall 100, and a mild steel flange plate 201 is fixedly connected to the side of the base plate 203;

[0029] In addition, a soft steel web 202 is arranged on the side of the soft steel flange plate 201, the side of the soft steel web 202 is fixedly connected to the base plate 203, the other side of the soft steel web 202 is fixedly connected to the top plate 204, the top plate 204 is fixedly connected to the side of the soft steel flange plate 201, and the side of the top plate 204 is cooperated with a connecting component 300.

[0030] Specifically, the fixed connection between the energy dissipation component 200 and the wall 100 allows the energy dissipation component 200 to directly provide energy dissipation protection for the wall 100. The coordinated arrangement of the mild steel flange plate 201 and the mild steel web 202 can protect the scissor wall from the combined attack of seismic transverse waves and vertical waves to the greatest extent. The coordinated arrangement of the connecting component 300 can help the energy dissipation component 200 to be suitable for walls 100 of different thicknesses, thereby increasing the scope of application of the energy dissipation component 200.

[0031] The connecting member 300 includes a side screw 301 fixedly connected to the top of the top plate 204, an intermediate screw 305 fixedly connected to the center of the outer surface of the top plate 204 through a bearing, the outer surface of the intermediate screw 305 is threadedly connected to the second sleeve 304, and the outer surface of the side screw 301 is threadedly connected to the first sleeve 302.

[0032] It should be noted that the threaded connection between the side screw 301 and the first sleeve 302 and the threaded connection between the intermediate screw 305 and the second sleeve 304 enable the connection member 300 to flexibly adjust the distance from the wall 100 by displacement, further ensuring that the energy dissipation member 200 exerts the best energy dissipation effect at an appropriate distance.

[0033] When in use, first fix the energy dissipation component 200 to one side of the wall 100, then fix the base plate 203 and the top plate 204 to the inner side of the wall 100, and fix the mild steel web 202 and the mild steel flange plate 201 between the base plate 203 and the top plate 204 respectively, for energy dissipation protection of the wall 100; then fix the side screw 301 on the end face of the top plate 204 and the middle screw 305 in the middle, and then thread the first sliding sleeve 302 and the second sliding sleeve 304 with the side screw 301 and the middle screw 305, so that the energy dissipation component 200 can exert the best energy dissipation effect at the appropriate position.

[0034] Example 2

[0035] Reference Figure 2-3 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides relevant parts for the limiting locking effect of the second sliding sleeve.

[0036] Specifically, there are several first sleeves 302, and the tops of several first sleeves 302 are fixedly connected with energy dissipation plates 312. The side surfaces of the first sleeves 302 and the side surfaces of the second sleeves 304 are rotatably connected with straight rods 303 through ear plates, and the side fixed sleeves of the second sleeves 304 are provided with oil seal rings 306.

[0037] Among them, the fixed connection between the energy dissipation plate 312 and the first sliding sleeve 302 can, on the one hand, eliminate the shaking of the wall 100 and increase the stability of the wall 100; on the other hand, it can reduce the structural strength effect caused by the stress of the web and flange plates by means of energy dissipation, thereby extending the service life of the web and flange plates. At the same time, the oil seal ring 306 mounted on the outer wall of the second sliding sleeve 304 can ensure the stable displacement of the second sliding sleeve 304.

[0038] The second sliding sleeve 304 is matched with an intermediate screw rod 305 , the bottom of which is fixedly connected to a base 309 via a stabilizing seat, and a spur gear 307 is fixedly sleeved on the outer side surface of the second sliding sleeve 304 .

[0039] Furthermore, the base 309 can provide support and stability for the intermediate screw 305 to ensure the stability of the intermediate screw 305. The sleeve of the spur gear 307 and the second sleeve 304 can limit and lock the second sleeve 304, helping the energy dissipation component 200 to be permanently embedded in a suitable position.

[0040] When in use, the energy dissipation plate 312 is fixedly connected to the first sleeve 302 , and then the straight rod 303 is rotatably connected between the first sleeve 302 and the second sleeve 304 , and the oil seal ring 306 is sleeved and connected to the second sleeve 304 to ensure the sliding stability of the second sleeve 304 .

The end face of the locking piece 308 is fixedly connected to a pull rod 311, and the pull rod 311 is an integrally formed steel rod. There are two locking pieces 308, and the teeth of the locking piece 308 are arc-shaped teeth, and the inner edges of the two arc-shaped teeth are meshed with the teeth of the spur gear 307.

[0044] Furthermore, the fixed connection between the locking member 308 and the limiting block 310 allows the locking member 308 to be displaced and pushed, and the second sliding sleeve 304 is stably limited and locked. The fixed connection between the pull rod 311 and the locking member 308 can help the locking member 308 to actively slide, thereby helping to stably lock the arc teeth and the spur gear 307.

[0045] When in use, the limiting block 310 is fixed on the side of the locking member 308, and a through groove is opened between the limiting block 310 and the base 309 to complete the sliding. At the same time, the pull rod 311 is installed on the end face of the locking member 308 to push the arc teeth on the inner side of the locking member 308 to engage and lock with the teeth of the spur gear 307.
