Elevated floor capable of being doubled as plenum chamber and construction method thereof

Abstract

Provided are an elevated floor capable of being doubled as a plenum chamber and a construction method thereof. The elevated floor comprises an elevated floor body and the plenum chamber. The elevatedfloor body comprises a frame which stands on the ground and is arranged around a center building and surface plates laid on the whole frame body. The frame comprises a set of adjustable bases, a set of vertical rods, a set of brackets and a set of cross rods. The adjustable bases and the bottom ends of the vertical rods are vertically adjustable and are in threaded connection. Each bracket comprises a supporting plate, a stand rod sleeve and a bracket convex head, each surface plate comprises a set of unit surface plates, and each unit surface plate comprises a plate body, a steel frame and abracket bearing groove. According to the elevated floor, an elevated platform is provided, and the problem of elevating leveling is solved; meanwhile, an air supply area is tightly blocked, and the lower space of the elevated platform is fully utilized for ground static-pressure air supply; the frame body has enough rigidity, and therefore the platform can meet the normal people stream load needs;and the air supply plenum chamber on the lower portion of the elevated floor is even in air supply, the elevated floor and the plenum chamber can be used in commo through the whole system, mounting and demounting are fast, and the elevated floor and the plenum chamber can be cyclically used.

Description

technical field [0001] The invention relates to an elevated floor, in particular to an elevated floor which can double as a static pressure box and a construction method thereof. Background technique [0002] The static pressure box is a necessary accessory for the air supply system to reduce dynamic pressure, increase static pressure, stabilize airflow and reduce airflow vibration, which can make the air supply effect more ideal. Traditional plenums are often made of iron sheets and must be installed and fixed. They are permanent pipelines and require a large space. The traditional raised floor is permanently fixed, and it cannot be used repeatedly and quickly. The function of the ground air supply plenum and the raised floor need to solve the problems of leveling the ground height difference and sealing. It is difficult to coordinate and arrange the static pressure box and the elevated floor space, and there are many problems in design and construction. The traditional m...

Problems solved by technology

[0003] The purpose of the present invention is to provide a raised floor that can double as a static plenum and its construction method, to solve the technical problems that the elevated floor needs to be leveled and the ground height difference needs to be leveled and the static plenum needs to be installed and fixed separately and takes up a large space. To solve the difficulty in coordinating and arranging the static plenum and the raised floor in space, there are many design and construction problems, all of which are technical problems that cannot be turned around in one permanent construction
