Description

Technical Field

[0001] This utility model relates to a vibration reduction structure for building structures, specifically to a connection structure of a plate viscoelastic damper in a structure. Background Technology

[0002] In recent years, with the increasing development and maturity of the field of building structure vibration reduction technology, vibration reduction technology has rapidly developed in new construction and reinforcement projects. Viscoelastic dampers have been widely used in specific structures due to their low cost, space saving, and high temperature stability.

[0003] Currently, the following are some typical connection methods for viscoelastic dampers in engineering:

[0004] 1) Welded connection:

[0005] Implementation method: The outer steel plate layer of the damper is directly welded to the steel components of the main structure or the pre-embedded steel plate.

[0006] Limitations: It cannot be replaced; the high temperature generated during welding can easily damage the rubber layer in the viscoelastic damping layer.

[0007] 2) Bolted connection:

[0008] Implementation method: The end plate of the damper is fixed to the embedded parts or connecting plates in the main structure by high-strength bolts.

[0009] Limitations: High installation accuracy and strict control of bolt preload are required.

[0010] 3) Pin connection:

[0011] Implementation: The damper is hinged to the structure via an earring seat and a pin, allowing for multi-directional rotation.

[0012] Limitations: High machining requirements for the pin and pin hole, and high precision requirements during on-site installation.

[0013] Therefore, a new viscoelastic damper connection method is needed to solve the above problems. Utility Model Content

[0014] To address the technical problems of high-temperature welding and inconvenient assembly / disassembly in the above-mentioned viscoelastic damper connection methods, this utility model provides a connection structure for a plate viscoelastic damper.

[0015] This utility model provides the following technical solution:

[0016] A connection structure for a plate viscoelastic damper includes a viscoelastic damper, a pin, and a connector. The viscoelastic damper is connected to the connector via the pin. The viscoelastic damper consists of two side connecting steel plates, a middle connecting steel plate, and a viscoelastic damping layer. The viscoelastic damping layers are symmetrically arranged on both sides of the middle connecting steel plate, and the two side connecting steel plates are located outside the viscoelastic damping layers.

[0017] Furthermore, the viscoelastic damping layer is composed of several rubber layers and several steel plate layers, which are alternately stacked and vulcanized to form the rubber layers. The rubber layers are vulcanized together with the steel plates on both sides and the steel plate in the middle.

[0018] Furthermore, the connector consists of a double-clamp plate and a single-clamp plate. The double-clamp plate is connected to the middle connecting steel plate pin by a pin shaft, and the single-clamp plate is connected to the two side connecting steel plates pin by a pin shaft.

[0019] Furthermore, the connector is connected to the steel components of the main structure or the embedded steel plate by welding.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] (1) The viscoelastic damper is connected to the structure using pins and connectors. The pin connection section is isolated from the viscoelastic damping layer, which effectively solves the influence of high welding temperature on the viscoelastic damping layer.

[0022] (2) The pin connection method facilitates later maintenance, and it is more convenient to maintain and replace the viscoelastic damper by disassembling the pin shaft;

[0023] (3) The pin connection process, which requires high precision, is completed in the factory through process control, thus achieving integrated production and installation of pin connections and effectively ensuring production and installation precision and installation quality.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-3 This utility model discloses a connection structure for a plate viscoelastic damper in a structure, used for connecting the viscoelastic damper to the main structure. It includes a viscoelastic damper 1, a pin 2, and a connector 3. The viscoelastic damper 1 is connected to the connector 3 by the pin 2. The viscoelastic damper 1 is composed of two side connecting steel plates 4, a middle connecting steel plate 5, and a viscoelastic damping layer 6. The viscoelastic damping layers 6 are symmetrically arranged on both sides of the middle connecting steel plate 5, and the two side connecting steel plates 4 are located on the outside of the viscoelastic damping layers 6.

[0030] The viscoelastic damping layer 6 is composed of several rubber layers 601 and several steel plate layers 602. The rubber layers 601 and steel plate layers 602 are alternately stacked and vulcanized to form a bond. The rubber layers 601 are vulcanized together with the steel plates 4 on both sides and the steel plate 5 in the middle.

[0031] The viscoelastic damping layer 6 is rectangular, circular, or fan-shaped.

[0032] The connector 3 consists of a double-clamp plate 7 and a single-clamp plate 8. The double-clamp plate 7 is connected to the middle connecting steel plate 5 by a pin 2, and the single-clamp plate 8 is connected to the two side connecting steel plates 4 by a pin 2. All assembly is completed in the factory.

[0033] Pin holes are pre-drilled at the ends of the double-clamp plate 7 and the single-clamp plate 8, with a tolerance of +0.05mm to +0.3mm. The double-clamp plate 7 is drilled to mate with the intermediate connecting steel plate 5, and the pin connection is completed at the factory. The single-clamp plate 8 is drilled to mate with the two side connecting steel plates 4, and the pin connection is completed at the factory.

[0034] Connector 3 is connected to the steel components or embedded steel plates of the main structure by welding. That is, the ends of the double-clamp plate 7 and the single-clamp plate 8 are connected to the steel components or embedded steel plates of the main structure by welding on the construction site.

[0035] Pre-machined pin holes are provided at the ends of the connecting steel plates on both sides (4) and the end of the connecting steel plate in the middle (5). The tolerance of the pin holes is +0.05mm to +0.3mm.

[0036] The viscoelastic damper 1 is welded to the steel component or embedded steel plate of the main structure using the connector 3, which effectively avoids the high temperature during welding from damaging the viscoelastic damping layer 6, and at the same time facilitates the later disassembly of the pin 2 to replace the viscoelastic damper 1.

[0037] This invention utilizes pins and connectors to connect the viscoelastic damper to the structure, avoiding damage to the rubber layer in the viscoelastic damping layer caused by the high temperature generated during welding. It also facilitates the maintenance and replacement of the viscoelastic damper by disassembling the pins later. This solves the accuracy and quality problems in the production and installation process of plate viscoelastic dampers, effectively improving construction efficiency and installation quality.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
