Description

Technical Field

[0001] This utility model belongs to the technical field of vibration reduction devices for buildings, and particularly relates to a combined vibration reduction device for a steel frame floating platform. Background Technology

[0002] During building construction, the installation of large electromechanical equipment on the roof and equipment floor is carried out in order to avoid large vibrations during operation, which could lead to equipment instability and damage to the building structure. Therefore, in order to implement vibration reduction and noise reduction management, the conventional practice is to use a floating platform with structural strip foundations and vibration dampers for vibration reduction.

[0003] However, in conventional practices, vibration reduction and noise reduction using floating platforms are often necessary for some equipment due to pipe connection requirements. In such cases, the floating platform requires secondary casting of strip or column foundations on the original foundation. This conventional practice of casting concrete foundations in place can easily lead to poor structural flatness and the need for secondary repairs after casting, making it impossible to guarantee strength. Furthermore, cracking is likely to occur later, affecting the vibration reduction effect on the equipment. Therefore, this utility model proposes a new solution to the above-mentioned technical problems. Utility Model Content

The adjustable supports 3 include an adjustable support body 31 and a movable adjustment structure 32 for height adjustment. The adjustable support body 31 is connected to the first mounting position 23. The movable adjustment structure 32 is connected to the adjustable support body 31 and abuts against the contact surface of the equipment for height adjustment.

The flanges of the H-beams are parallel inside and out, which facilitates the continuous opening of elongated holes as first mounting positions 23 on the flanges of the first steel section 21 and the second steel section 22, thereby improving the positioning accuracy and installation convenience of the adjustable support 3. The I-beams have thinner webs, and reinforcing ribs can be symmetrically welded on both sides of the web to form a local box-shaped section. This improves the local bearing capacity of the first steel section 21 and the second steel section 22 without increasing the height of the profiles, so as to adapt to the concentrated loads of different equipment bases and enhance the support stability of the steel structure frame 2.
