Assembly type operation platform of compound fertilizer granulation high tower and construction method of assembly type operation platform

Abstract

The invention discloses an assembly type operation platform of a compound fertilizer granulation high tower and a construction method thereof, the operation platform comprises: two truss side beams which are arranged in parallel at an interval, and two ends of the two truss side beams are respectively fixed on the inner tower wall of the high tower; the light prefabricated bottom plate is fixedly mounted between the bottom ends of the two truss side beams; and the multiple transverse supporting top rods are arranged at intervals, and the two ends of the multiple transverse supporting top rods are fixedly installed between the top ends of the two truss side beams correspondingly. The operation platform is simple in structure and light in weight, the truss side beams and the light prefabricated bottom plate are machined under the tower, then the machined truss side beams and the light prefabricated bottom plate are hoisted to the tower to be installed, and the operation platform has the advantages of being short in construction time, low in construction cost, high in safety and easy to construct and install.

Description

technical field [0001] The invention relates to the technical field of compound fertilizer granulation towers, and more specifically relates to an assembled operation platform of a high compound fertilizer granulation tower and a construction method thereof. Background technique [0002] The compound fertilizer granulation tower is a new type of concrete structure (or steel structure) high tower. The air pressure difference between the upper and lower sides of the high tower forms a ventilation effect similar to a chimney (or cooling water tower). The molten slurry is sprayed on the tower and exchanged with the cold wind for cooling. Granular solids, compound fertilizer granulation tower is a special chemical structure, the height of the tower is usually more than 100m, and the tower wall is usually constructed with sliding film. [0003] The characteristic of the compound fertilizer granulation tower is that an operating platform for carrying related equipment is built abov...

AI Technical Summary

Problems solved by technology

However, the existing operating platform structure is generally to build a special construction platform on a high tower, and then erect a formwork cast-in-place concrete beam, wall, and board on the construction platform. Its volume is heavy, and high-altitude construction is dangerous and difficult to build. The method of platform is that after the concrete slide film of the tower body reaches the top, when the strength of the concrete reaches 100% requirements, the radiation beam method is used to construct the inner sleeve operation layer platform on the upper part of the granulation tower or the construction of the strong beam structure. It is necessary to build a construction platform at a height of 70-90m in the tower for the construction of the upper operation platform, resulting in long construction time, high construction cost, high difficulty in platform erection, and high risk of platform structure
