Description

Technical Field

[0001] This utility model relates to the field of energy dissipation wall vibration reduction technology, specifically to an energy dissipation wall vibration reduction structure. Background Technology

[0002] In the construction field, to achieve good seismic performance, energy dissipation and vibration reduction structures are typically designed inside buildings, especially in high-rise and super high-rise buildings. Traditional structural seismic design mainly relies on the strength, stiffness, and ductility of the structure itself to resist earthquake forces. Numerous earthquake examples show that after a major earthquake, the main structure itself will suffer some degree of damage and destruction, and in severe cases, irreversible consequences may occur. The energy dissipation and vibration reduction devices used in structural energy dissipation and vibration reduction designs can consist of energy dissipators and supporting components such as braces, walls, and beams. Currently, commonly used displacement-related energy dissipators are classified into shear yield type and axial yield type according to their yield form.

[0003] In the current use of energy dissipation wall structures, most methods involve drilling holes in the wall and using screws for positioning. However, during use, the energy dissipator repeatedly exerts reverse forces on the screws, causing them to experience repeated tensile forces. This makes the screws prone to loosening and falling off after installation, affecting stability. Therefore, manual application of screw glue is required to improve the stability of the screw installation. However, manual application is not uniform, and the glue is prone to overflowing due to gravity during the application process. Therefore, it is necessary to provide a new type of energy dissipation wall vibration reduction structure to solve the above technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide an energy dissipation wall vibration reduction structure, which has good stability and can prevent the energy dissipator from falling off.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A novel energy dissipation wall vibration reduction structure includes: a lower wall, an upper wall, an energy dissipator, and two mounting plates. The lower wall and the upper wall are distributed vertically at intervals. Two threaded holes are opened on the bottom surface of the lower wall and the top surface of the upper wall. Screws are screwed into the threaded holes. The two mounting plates are fixed to the lower wall and the upper wall respectively by screws. The two ends of the energy dissipator are hinged to the two mounting plates respectively.

[0007] The screw has an internal cavity, a glue bladder is installed in the upper part of the cavity, a piston is slidably connected to the lower part of the cavity, a sliding rod is fixedly connected to the bottom of the piston, a protrusion for piercing the glue bladder is fixedly provided on the top of the piston, a limiting spring is sleeved on the outside of the screw, and several overflow holes communicating with the cavity are opened on the outer wall of the screw.

[0008] Compared with the prior art, the advantages of this utility model are:

[0009] 1. The utility model, through the cooperation of threaded holes, mounting plates, and screws, enables the simultaneous assembly of an energy dissipator between the upper and lower walls. During installation, the screw needs to be rotated to engage with the threaded hole. As the screw is rotated deeper into the threaded hole, when the sliding rod contacts the bottom of the threaded hole, the sliding rod slides upward inside the screw. Simultaneously, the piston moves upward inside the screw, eventually allowing the protrusion to contact and pierce the glue bladder. After the glue bladder is pierced by the protrusion, the glue inside overflows. As the piston continues to move upward, the glue is pressurized and flows out from the overflow hole, filling the screw and the threaded hole, thereby improving the stability of the energy dissipator.

[0010] 2. When the rotating screw is limited, the elastic force of the limiting spring can act on the screw in the opposite direction, so that the screw will not easily loosen or fall off after installation, and further assists the glue to improve the stability of the screw after installation.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0018] like Figure 1-5 The diagram shown is a schematic representation of an embodiment of the energy dissipation wall vibration reduction structure provided by this utility model:

[0019] An energy dissipation wall vibration reduction structure includes:

[0020] The structure consists of a lower wall 1, an upper wall 2, an energy dissipator 3, and two mounting plates 4. The lower wall 1 and the upper wall 2 are arranged vertically at intervals. The bottom surface of the lower wall 1 and the top surface of the upper wall 2 each have two threaded holes 5. Screws 6 are screwed into the threaded holes 5. The two mounting plates 4 are fixed to the lower wall 1 and the upper wall 1 respectively by the screws 6. The two ends of the energy dissipator 3 are hinged to the two mounting plates 4 respectively.

[0021] The screw 6 has a cavity inside, a glue bag 10 is installed at the upper part of the cavity, a piston 15 is slidably connected to the lower part of the cavity, a sliding rod 11 is fixedly connected to the bottom of the piston 15, a protrusion 16 for piercing the glue bag 10 is fixedly provided at the top of the piston 15, a limiting spring 7 is sleeved on the outside of the screw 6, and several overflow holes 17 communicating with the cavity are opened on the outer wall of the screw 6.

[0022] It should be specifically noted that the energy dissipator 3 is a product that can be purchased directly from the market, and its principle, connection method and control method are all existing technologies well known to those skilled in the art.

[0023] The overflow holes 17 are arranged in a ring array on the outer wall of the screw 6.

[0024] The bottom of the slide rod 11 is fixedly connected to a cap 12, which is hemispherical in shape.

[0025] The slide rod 11 is fitted with a retaining sleeve 8, and a lever 9 is fixedly connected to the outside of the retaining sleeve 8. The retaining sleeve 8 can limit the slide rod 11 and prevent the glue bag 10 from being punctured when not in use.

[0026] A return spring 14 is installed between the piston 15 and the glue bag 10. A protective plate 13 is fixed on the top of the return spring 14, and the protective plate 13 is made of rubber.

[0027] The general usage of this utility model is as follows:

[0028] First, the corresponding threaded holes 5 are prepared. Then, using two mounting plates 4 and four screws 6, the energy dissipator 3 can be installed between the upper wall 2 and the lower wall 1. During installation, the screws 6 need to be rotated to engage with the threaded holes 5. As the screws 6 are rotated, the sliding rod 11 extends into the threaded hole 5 and contacts the bottom of the threaded hole 5. This causes the sliding rod 11 to slide upward inside the screw 6, simultaneously driving the piston 15 to move upward inside the screw 6. Finally, the protrusion 16 contacts and punctures the glue bladder 10. After the glue bladder 10 is punctured by the protrusion 16, the glue inside overflows. As the piston 15 continues to move upward, the glue is pressurized and flows out from the overflow hole 17, filling the screw 6 and the threaded hole 5. At the same time, when the screw 6 is rotated to a limit position, the elastic force of the limit spring 7 acts in the opposite direction on the screw 6, ensuring that the screw 6 will not easily loosen or fall off after installation, further assisting the glue in improving the stability of the screw 6 after installation.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
