A towering suspended micro-vibration equipment construction structure and its construction method

Abstract

The present invention provides a towering suspended micro-vibration equipment construction structure, including: a rigid support structure, including a foundation beam structure, a first-floor support structure and a second-floor support structure, the foundation beam and the first-floor support structure pass through a first-floor support beam ( 3) Connection. The support structure on the first floor is connected to the support structure on the second floor through the support beams (10) on the second floor, and the support columns (3) on the first floor are connected to the foundation beams. There are six concrete columns with circular cross-sections in total; the air flotation control system includes air Float system (14) and limiter (15), air flotation system (14) is an independent air spring structure composed of mechanical height valve, main air chamber, additional air chamber, air inlet and exhaust port, limiter (15) installed between the anti-microvibration T-stage (16) and the air flotation system (14); and the anti-microvibration T-stage (16), which provides a certain counterweight for the air flotation system (14) and has rigid body characteristics The supporting platform structure and place the radar detection equipment. Corresponding equipment construction methods are also provided.

Description

technical field [0001] The invention relates to the field of optical detection as vibration control, in particular to a towering suspension type optical detection micro-vibration equipment structure and a construction method thereof. Background technique [0002] For the space-independent detection environment, such as the electromagnetic shielding performance detection of radar and similar electronic components, etc., it is necessary to provide a high-performance micro-vibration environment in a closed electromagnetic wave anechoic chamber. At present, for towering, suspended, high-performance micro-vibration environments The precision equipment platform mainly adopts the construction technology of cast-in-place concrete. However, this type of construction process is rough, and it is difficult to meet the design requirements for vibration reduction and isolation of the equipment platform. In short, the shortcomings of traditional methods mainly include the following aspect...
