Description

Technical Field

[0001] This utility model relates to the field of energy dissipation and vibration reduction technology in building structures, specifically a connecting support suitable for small-output plate dampers. Background Technology

[0002] Small-output plate dampers are passive energy dissipation devices that provide additional stiffness and damping to the structure by utilizing the energy dissipation characteristics of viscoelastic materials during shear deformation. They are suitable for multi-story frame structures or frame structures with few walls, such as those used in hospitals and schools, and are characterized by their simple structure, economy, and durability.

[0003] Chinese Patent CN220704820U discloses a wall-mounted damper installation structure, including an upper steel reinforcement frame embedded inside an upper pier, a lower steel reinforcement frame embedded inside a lower pier, and a damper located between the upper and lower piers. Upper and lower embedded plates are pre-embedded in the upper and lower piers, respectively, and are connected and fixed to the top and bottom of the damper. The upper steel reinforcement frame includes multiple steel reinforcement supports, with reinforcing ribs connecting the supports on their outer sides. The advantages are: this invention uses an assembly method for damper installation, allowing for pre-production and significantly shortening the construction period, reducing labor costs, and saving labor expenses; this technology can increase the seismic stability of buildings; when a building is subjected to an earthquake, the damper absorbs the energy generated by the shaking, reducing damage to the building structure, ensuring structural stability, and achieving the goal of seismic reinforcement.

[0004] The damper connection piers in the above scheme and existing technology are usually reinforced concrete piers. Using all reinforced concrete piers has a significant impact on the structure and is too wasteful. There is a lack of corresponding relatively economical combined masonry pier structures in this area, so improvements and optimizations are needed. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: A connecting support for a small-output plate damper includes a small-output plate damper, one end of which is fixedly connected to a lower support assembly, and one end of which is fixedly connected to an upper support assembly. One end of the lower support assembly is fixedly connected to a beam, and beam-embedded steel plates are symmetrically and fixedly embedded in the middle of the beam, and beam-embedded reinforcing bars are also pre-embedded and fixedly connected in the middle of the beam.

[0008] Preferably, the lower support assembly includes a lower concrete body, which is poured and connected to the inner side of the beam embedded steel plate. The lower concrete body is internally fixedly connected to the beam embedded reinforcing bars. Two sets of first side steel plates are symmetrically fixedly connected to both ends of the lower concrete body. One end of the first side steel plate is fixedly welded to one end of a beam embedded steel plate, and the other end of the first side steel plate is fixedly welded to the lower steel plate of the damper.

[0010] Preferably, the two ends of the first annular reinforcing bar are respectively fixedly welded to the inner wall of a first side steel plate, and the two sets of binding ends in the first annular reinforcing bar are placed in opposite directions.

[0011] Preferably, the upper support assembly includes a third masonry, one end of which is fixedly connected to the upper steel plate of the damper, and two sets of second side steel plates are symmetrically fixedly connected to both ends of the third masonry.

They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Please see Figures 1-4 The present invention provides the following two preferred embodiments: Example 1: A connecting support for a small-output plate damper includes a small-output plate damper 1, with a lower support assembly fixedly connected to one end of the small-output plate damper 1 and an upper support assembly fixedly connected to one end of the small-output plate damper 1. One end of the lower support assembly is fixedly connected to a beam 4. Beam embedded steel plates 5 are symmetrically and fixedly embedded in the middle of the beam 4, and beam embedded reinforcing bars 6 are also pre-embedded and fixedly connected in the middle of the beam 4. The small-output plate damper 1 includes a composite buffer body 101, a lower damper steel plate 102, and an upper damper steel plate 103. The lower damper steel plate 102 is fixedly connected to one end of the composite buffer body 101, and the upper damper steel plate 103 is fixedly connected to the other end of the composite buffer body 101. The lower support assembly includes a lower concrete body 201, which is cast and connected to the beam embedded steel plate 6. Inside the slab 5, the lower concrete body 201 is fixedly connected to the pre-embedded steel bars 6 of the beam. Two sets of first side steel plates 202 are symmetrically fixedly connected to both ends of the lower concrete body 201. One end of the first side steel plate 202 is fixedly welded to one end of a pre-embedded steel plate 5 of the beam, and the other end of the first side steel plate 202 is fixedly welded to the lower steel plate 102 of the damper. One end of the lower concrete body 201 is fixedly connected to a first masonry 203, and one end of the first masonry 203 is fixedly connected to a second masonry 205. Two sets of first ring steel bars 204 are symmetrically fixedly connected inside the second masonry 205. One end of the second masonry 205 is fixedly connected to the lower steel plate 102 of the damper. Both ends of the first ring steel bars 204 are fixedly welded to the inner wall of a first side steel plate 202, and the two sets of binding ends of the first ring steel bars 204 are placed in opposite directions.

[0018] In use, when pouring the lower beam 4, two sets of pre-embedded steel plates 5 and multiple sets of pre-embedded steel bars 6 are installed. When constructing the lower support pier assembly, formwork is erected between the two sets of pre-embedded steel plates 5, and the lower concrete 201 is poured. The multiple sets of pre-embedded steel bars 6 are then poured into the lower concrete 201. A set of first side steel plates 202 is welded upwards from one end of each of the two sets of pre-embedded steel plates 5. A first masonry 203 is built on the upper end of the lower concrete 201, followed by a second masonry 205 on top of the first masonry 203. The upper and lower ends of the second masonry 205 are respectively pre-embedded with first annular steel bars 204. The upper and lower sets of first annular steel bars 204 are also pre-embedded. The binding ends of the reinforcing bars 204 are placed in opposite directions, and the two ends of the first ring reinforcing bars 204 are respectively welded to the inner wall of the first side steel plate 202, which increases the strength and stability of the structure. Then, the lower steel plate 102 of the damper on the small output plate damper 1 is fixedly connected to the upper end of the second masonry 205, and the two ends of the lower steel plate 102 of the damper are welded to one end of the first side steel plate 202. The spacing of the ring reinforcing bars is determined according to the height of the pier, and the spacing is not greater than 600mm and is uniformly set. When the beam 4 is a steel beam, it is not necessary to pre-embed the pre-embedded steel plate 5 and the pre-embedded reinforcing bars 6. At this time, the first side steel plate 202 is directly welded to the flange plate.

One end of the second side steel plate 302 is fixedly connected to a top embedded part 305. One end of the fourth masonry 303 is fixedly connected to a top concrete body 306.

[0020] When using the construction of the upper support pier assembly, a third masonry 301 is built on the upper steel plate 103 of the damper, and a second side steel plate 302 is welded to both ends of the upper steel plate 103 of the damper.
