Description

Technical Field

[0001] This utility model relates to the field of building support technology, specifically to a metal building support with a vibration damping and sound insulation mechanism, which can effectively alleviate the problem of noise transmission through structural components. Background Technology

[0002] Noise complaints from elevators in high-rise buildings are on the rise and are difficult to resolve. Some noise is transmitted through solid media, and the sound is amplified when the metal supports connecting the guide rails are located at the floor slab. The main problems are: 1) Vibration noise from the elevator is transmitted to residents through the guide rails, metal supports, concrete, or reinforcing steel, causing noise pollution; 2) The metal connecting components on the elevator shaft walls lack vibration damping and sound insulation treatment. Traditional vibration damping and sound insulation methods involve installing insulating rubber to reduce the vibration noise transmitted to the reinforced concrete shaft during elevator car operation. However, this rubber ages over time, affecting its vibration damping performance, and is difficult to replace, eventually losing its damping effect. Therefore, the research objective of this utility model is to design a metal building support with a vibration damping and sound insulation mechanism that, while ensuring stable performance, extends the connection path through structural improvements and incorporates energy-dissipating and vibration-damping methods to achieve a true vibration damping and sound insulation effect. Utility Model Content

[0003] In view of the technical problems existing in the prior art, the present invention provides a metal building support with a vibration damping and sound insulation mechanism, which can effectively solve the technical problems existing in the prior art.

[0004] The technical solution of this utility model is: A metal building support frame with vibration damping and sound insulation mechanism, comprising: A number of connecting parts are provided, with two connecting parts symmetrically spaced to form a fixed assembly. Each connecting part consists of a fastening part, a buffer part, and a fixing part connected in sequence in a Z-shape or S-shape. The connecting parts are locked and fixed to the wall by bolts that pass through the fixing part. The guide rail is installed between the gaps of the two connecting members. Multiple sets of fixing components are arranged vertically on the guide rail 2. The fastening part of the connecting member is attached to the front side wall of the guide rail. The two sides of the guide rail are set as inclined planes parallel to the buffer part of the connecting member and spaced apart. The inner side of the guide rail is spaced apart from the wall. The reinforcing mechanism includes a reinforcing plate fixedly connecting the included angle of the fastening part and the buffer part, and the included angle of the buffer part and the fixing part. The reinforcing plate and the connector are connected to form a corresponding receiving cavity and filled with vibration damping particles. Corresponding closing plates are fixedly installed at both ends of the receiving cavity.

[0005] The metal building support also includes an elastic element fixed to the wall by a corresponding embedded part. When the guide rail is installed, its inner side is attached to the other end of the elastic element that is not connected to the embedded part. The embedded part includes a hollow shell fixed to the wall or inside the wall, and the hollow shell is filled with corresponding vibration damping particles.

[0006] The vibration damping particles are vibration damping cotton or damping particles.

[0007] A pre-fixed plate is pre-secured to the wall by bolts. The pre-fixed plate has a trapezoidal groove that is narrower on the outside and wider on the inside. The connector has a trapezoidal strip that matches the trapezoidal groove. The connector is laterally limited and slidably installed on the pre-fixed plate by connecting the trapezoidal strip with the trapezoidal groove. The pre-fixed plate has several through holes, and the wall has corresponding mounting holes at positions corresponding to the through holes. When the guide rail is installed, after the connector moves to the guide rail side, the bolts on the connector are rotated inward and locked through the through holes and mounting holes respectively.

[0008] The end of the guide rail adjacent to the fastening part of the connector is provided with a chamfer that is adapted to the reinforcing plate. When the connector moves into place, the chamfer is fitted and connected to the reinforcing plate.

[0009] Advantages of this utility model: 1) This utility model uses multiple sets of symmetrical Z-shaped or S-shaped connectors with spacing for mounting the guide rail. The front side wall of the guide rail is fitted with the fastening part of the connector for snap-fit ​​fixation. The guide rail and the buffer part are spaced apart, thereby extending the length of the connection between the guide rail and the wall without extending the length of the equipment. By extending the vibration transmission path, the amount of vibration transmitted to the wall is reduced, thereby achieving the effect of vibration reduction and sound insulation.

[0010] 2) The present invention further provides reinforcing plates at the angle between the fastening part and the buffer part of the connector, and at the angle between the buffer part and the fixing part, to enhance the strength of the connector and ensure the stability of the guide rail installation. The reinforcing plate and the connector form a cavity and are filled with vibration damping particles. When the sound waves pass through the sound insulation cotton, they are reflected, superimposed, and collided by countless fibers, which converts the sound wave energy into heat energy to weaken the sound wave intensity. Alternatively, the energy is dissipated by the friction between the damping particles to isolate and reduce the amount of vibration transmitted to the wall, thereby achieving the effect of vibration reduction and sound insulation.

[0011] 3) To further reduce the transmission of vibration from the inner side of the guide rail to the wall, in addition to fixing the guide rail by interlocking two connectors, this utility model also fixes an elastic element to the wall by pre-embedded parts. When the guide rail is installed, the inner side is attached to the elastic element, and the pre-embedded parts are filled with vibration damping particles. By converting the vibration energy into the potential energy of the elastic element, the vibration transmitted to the wall and the energy dissipation due to the friction between the damping particles are reduced, thereby isolating and reducing the amount of vibration transmitted to the wall, further reducing vibration and sound insulation, and thus improving the practical effect of this utility model.

[0012] 4) To ensure convenient and stable installation, this utility model adds a pre-fixed plate that is pre-fixed to the wall by bolts. The connector is laterally limited and slidably installed on the pre-fixed plate by a trapezoidal strip and a trapezoidal groove. When installing the guide rail, the pre-installed connector moves relative to the guide rail and is locked on it. A through hole is provided on the pre-fixed plate to connect with the wall mounting hole. After the position of the connector is determined, the connector is rotated inward by bolts and locked to the wall through the through hole and the mounting hole respectively, thereby strengthening the connection stability between the connector and the pre-fixed plate.

[0018] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings: refer to Figure 1-4 A metal building support frame with vibration damping and sound insulation mechanism, comprising: A plurality of connecting parts 1 are arranged symmetrically at intervals to form a fixed assembly. Each connecting part 1 is formed by connecting a fastening part 101, a buffer part 102 and a fixing part 103 in sequence in a Z-shape or S-shape. The connecting parts 1 are locked and fixed to the wall by bolts that pass through the fixing part 103. The guide rail 2 is installed between the gaps of the two connecting parts 1. Multiple sets of fixing components are arranged vertically on the guide rail 2. The fastening part 101 of the connecting part 1 is attached to the front side wall of the guide rail 2. The two sides of the guide rail 2 are set as inclined planes parallel to the buffer part 102 of the connecting part 1 and spaced apart. The inner side of the guide rail 2 is spaced apart from the wall. The reinforcing mechanism includes a reinforcing plate 3 fixedly connecting the angle between the fastening part 101 and the buffer part 102, and the angle between the buffer part 102 and the fixing part 103. The reinforcing plate 3 and the connecting member 1 are connected to form a corresponding receiving cavity and filled with vibration damping particles 4. Corresponding closing plates 5 are fixedly installed at both ends of the receiving cavity.

[0019] This utility model uses multiple sets of symmetrical Z-shaped or S-shaped connectors 1 arranged at intervals to install the guide rail 2. The front side wall of the guide rail 2 is fitted and locked to the fastening part 101 of the connector 1. The guide rail 2 is spaced apart from the buffer part 102. Thus, without extending the length of the equipment, the length of the connection between the guide rail 2 and the wall is extended. By extending the vibration transmission path, the amount of vibration transmitted to the wall is reduced, thereby achieving the effect of vibration reduction and sound insulation.

[0020] This utility model further provides reinforcing plates 3 at the angle between the fastening part 101 and the buffer part 102 of the connector 1, and at the angle between the buffer part 102 and the fixing part 103, to enhance the strength of the connector 1 and ensure the stability of the guide rail 2 installation. The reinforcing plate 3 and the connector 1 are connected to form a cavity and filled with vibration damping particles 4. When sound waves pass through the sound insulation cotton, they are reflected, superimposed, and collided by countless fibers, converting the sound wave energy into heat energy to weaken the sound wave intensity. Alternatively, the energy is dissipated by the friction between the damping particles to isolate and reduce the amount of vibration transmitted to the wall, thereby achieving the effect of vibration reduction and sound insulation.

[0021] The metal building support also includes an elastic element 7 fixed to the wall by a corresponding embedded part 6. When the guide rail 2 is installed, its inner side is attached to the other end of the elastic element 7 that is not connected to the embedded part 6. The embedded part 6 includes a hollow shell fixed to the wall or inside the wall, and the hollow shell is filled with corresponding vibration damping particles 4.

[0022] The vibration damping particles 4 are vibration damping cotton or damping particles.

[0023] To further reduce the transmission of vibration from the inner side of the guide rail 2 to the wall, in addition to fixing the guide rail 2 by connecting two connectors 1 together, this utility model also fixes the elastic element 9 to the wall by pre-embedded part 6. When the guide rail 2 is installed, the inner side is attached to the elastic element 9, and the pre-embedded part 6 is filled with vibration damping particles. By converting the vibration energy into the potential energy of the elastic element 9, the vibration transmitted to the wall and the energy dissipation due to mutual friction of the damping particles are reduced, so as to isolate and reduce the amount of vibration transmitted to the wall, further reduce vibration and sound insulation effect, and thus improve the practical effect of this utility model.

[0024] A pre-fixed plate 7 is pre-fixed to the wall by bolts. The pre-fixed plate 7 has a trapezoidal groove 701 that is narrower on the outside and wider on the inside. The connector 1 has a trapezoidal strip 8 that matches the trapezoidal groove 701. The connector 1 is laterally limited and slidably installed on the pre-fixed plate 7 by connecting the trapezoidal strip 8 with the trapezoidal groove 701. The pre-fixed plate 7 has several through holes 702, and the wall has corresponding mounting holes at positions corresponding to the through holes 702. When the guide rail 2 is installed, after the connector 1 moves to one side of the guide rail 2, the bolts on the connector 1 are rotated inward and locked through the through holes 702 and the mounting holes 702 respectively.

[0025] The end of the guide rail 2 adjacent to the fastening part 101 of the connector 1 is provided with a chamfer that is adapted to the reinforcing plate 3. When the connector 1 is moved into place, the chamfer is fitted and connected to the reinforcing plate 3.

[0026] To ensure convenient and stable installation, this utility model adds a pre-fixed plate 7 that is pre-fixed to the wall by bolts. The connector 1 is laterally limited and slidably installed on the pre-fixed plate 7 by a trapezoidal strip 8 and a trapezoidal groove 701. When installing the guide rail 2, the pre-installed connector 1 moves relative to the guide rail 2 and is locked on the guide rail 2. A through hole 702 is provided on the pre-fixed plate 7 to connect with the wall mounting hole. After the position of the connector 1 is determined, the connector 1 is rotated inward by bolts and locked to the wall through the through hole 702 and the mounting hole respectively, thereby strengthening the connection stability between the connector 1 and the pre-fixed plate 7.

For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in embodiment one. The above description is only a preferred embodiment of the present utility model.
