Embodiment Construction

[0058] The construction method of the present invention uses the FRP pultrusion profile as the core plate of the FRP floating plate to replace the existing honeycomb core plate, and uses the FRP light-cured prepreg as the bottom layer and the top layer of the FRP floating plate on the upper and lower sides of the pultrusion profile Reinforcing layer. Core board structure see figure 2 shown.

[0059] The specific construction process is to combine the characteristics of light-cured resin and FRP profiles. The steps are as follows:

[0060] 1. Welding floating disc outriggers

[0061] In order to ensure the tightness of the FRP floating plate, no outriggers are set on the FRP floating plate body, and the outriggers are welded to the bottom of the storage tank. The outriggers are made of 100*100mm H-shaped steel as columns, and the strength of the outriggers is far higher than the existing outriggers. The number of outriggers is only about one-fifth of that of ordinary floati...

Abstract

The invention discloses a novel FRP floating tray construction method. A FRP pultrusion profile serves as a core plate of an FRP floating tray, an existing honeycomb core plate is replaced, and on theupper and lower faces of the pultrusion profile, FRP light-cured prepreg serves as bottom and top layer reinforcement layers of the FRP floating tray. The construction method comprises the specific construction steps that 1, floating tray landing legs are welded; 2, no landing legs are arranged on an FRP floating tray body, and the landing legs are welded to the bottom of a storage tank; 3, a core layer is constructed; 4, construction of upper-layer FRP is carried out; 5, construction of bottom-layer FRP is carried out, 6, seals and accessories are installed; and 7, falling of the floating tray is carried out, and the floating tray is manufactured. The novel FRP floating tray construction method can solve the technical problems of high manufacturing cost, complicated construction equipment, slow construction speed and the like during construction of the FRP floating tray.

Description

technical field [0001] The invention relates to an improvement technology for an oil storage tank of an oil depot. In particular, it relates to a manufacturing method of a floating plate of a floating roof oil storage tank. Background technique [0002] With the increasing scale of oil storage tanks and oil depots, the requirements for floating trays of floating roof oil storage tanks are getting higher and higher. In recent years, there have been many accidents of floating roof storage tanks being struck by lightning, and the most serious one is the explosion accident of inner floating roof storage tanks being struck by lightning. Many of these internal floating roof storage tank accidents are caused by poor sealing of the floating plate, storage tank Explosive gas exists in the tank, and the concentration of oil and gas near the exhaust port of the storage tank exceeds the standard. At the same time, the loose sealing of the floating plate also causes a large amount of h...
