Description

Technical Field

[0001] This invention relates to the field of compound fertilizer granulation tower technology, and more specifically to a prefabricated operating platform for a compound fertilizer granulation tower and its construction method. Background Technology

[0002] Compound fertilizer granulation tower is a new type of high tower with a concrete (or steel) structure. The pressure difference between the top and bottom of the tower creates a ventilation effect similar to a chimney (or cooling tower). Molten slurry is sprayed on the tower and exchanged with cold air to form solid granules. Compound fertilizer granulation tower is a special chemical structure, usually more than 100m high, and the tower wall is usually constructed using a sliding membrane method.

[0003] The characteristic of compound fertilizer granulation towers is that an operating platform is built at a height of 70-90m inside the tower to house related equipment. However, existing operating platform structures generally involve erecting a dedicated construction platform on a high tower, and then installing formwork and cast-in-place concrete beams, walls, and slabs on the platform. This is heavy, involves high-altitude construction, is highly dangerous, and is difficult to construct. Furthermore, the construction method for the operating platform involves sliding the concrete of the tower to the top and waiting for the concrete to reach 100% strength before constructing the inner sleeve operating platform of the upper part of the granulation tower using the radial beam method or a stiffening beam structure. Both of these construction methods require the erection of a construction platform at a height of 70-90m inside the tower for the construction of the upper operating platform, resulting in long construction time, high construction costs, high platform erection difficulty, and high risks associated with the platform structure.

[0004] Therefore, how to provide a prefabricated operating platform for compound fertilizer granulation towers that is lightweight and easy to assemble, and its construction method, is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a prefabricated operating platform for a compound fertilizer granulation tower that is lightweight and easy to assemble, and its construction method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A prefabricated operating platform for a compound fertilizer granulation tower includes:

[0008] Truss side beams, wherein two truss side beams are arranged in parallel and spaced apart, and the two ends of the two truss side beams are respectively fixed to the inner tower wall of the tower;

[0009] A lightweight precast base slab is fixedly installed between the bottom ends of the two truss side beams;

[0010] The cross bracing is a plurality of cross bracing members arranged at intervals, and the two ends of the plurality of cross bracing members are respectively fixedly installed between the top ends of the two truss side beams.

[0011] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a prefabricated operating platform for a compound fertilizer granulation tower. The operating platform is composed of truss side beams, lightweight prefabricated base plates and cross bracing top rods. It has a simple structure, light weight, and adopts prefabricated installation, which makes the construction of the operating platform easy.

[0012] Furthermore, there are multiple lightweight precast base plates, which are spliced ​​together between the bottom ends of the two truss side beams.

[0013] The beneficial effect of adopting the above technical solution is that there are multiple lightweight prefabricated base plates, which facilitates the later stage of segmented hoisting and installation.

[0014] Furthermore, the surface of the truss side beams is covered with a layer of corrosion-resistant, lightweight, and flame-retardant material.

[0015] The beneficial effect of adopting the above technical solution is to improve the corrosion resistance and durability of the truss side beams.

[0016] Furthermore, the surface of the lightweight precast base plate is covered with a layer of corrosion-resistant, lightweight, and flame-retardant material.

[0017] The beneficial effect of adopting the above technical solution is to improve the corrosion resistance and durability of lightweight precast foundation slabs.

[0018] Furthermore, the cross brace is inclinedly arranged between the tops of the two truss side beams.

[0019] The beneficial effect of adopting the above technical solution is that the inclined arrangement of the cross bracing top rod can provide better support for the two truss side beams, making the two truss side beams more stable and improving the stability of the operating platform.

[0020] Furthermore, the truss side beams are made of steel.

[0021] The beneficial effects of adopting the above technical solution are that it is easy to process and manufacture, and has a lightweight structure and strong vertical load-bearing capacity.

[0022] This invention provides a construction method for a prefabricated operating platform for a compound fertilizer granulation tower, comprising the following steps:

[0023] Step S1: Fabricate the truss side beams and the lightweight precast base plate on the ground;

[0024] Step S2: Use the tower crane erected at the top of the tower to hoist the truss side beam. Specifically, during hoisting, the truss side beam is hoisted from the outside of the tower through the opening at the top of the tower to the inside of the tower. Then, the two ends of the truss side beam are fixed to the inner tower wall of the tower. Repeat step S2 to hoist another truss side beam to the inner tower wall of the tower and fix it, so that the two truss side beams are arranged in parallel and spaced apart.

[0025] Step S3: Use the tower crane to lift the lightweight precast base plate. Specifically, during the lifting process, the lightweight precast base plate is lifted from the outside of the tower through the opening at the top of the tower to the inside of the tower, and then the lightweight precast base plate is fixedly installed between the bottom ends of the two truss side beams.

[0026] Step S4: Use the tower crane to hoist the horizontal support top rod. Specifically, during hoisting, the horizontal support top rod is hoisted from the outside of the tower through the opening at the top of the tower to the inside of the tower. Then, the two ends of the horizontal support top rod are fixedly installed between the tops of the two truss side beams.

[0027] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a construction method for a prefabricated operating platform for a compound fertilizer granulation tower. This construction method involves processing truss side beams and lightweight prefabricated base plates under the tower, and then hoisting the processed truss side beams and lightweight prefabricated base plates onto the tower for installation. It has the advantages of short construction time, low construction cost, high safety, and easy construction and installation.

[0028] Furthermore, step S1 also includes wrapping the surfaces of the truss side beams and the lightweight precast base plate with a layer of corrosion-resistant, lightweight, and flame-retardant material.

[0029] The beneficial effects of adopting the above technical solution are that the complete anti-corrosion lightweight flame-retardant material wrapping at the bottom of the tower eliminates the need for operations on the tower, which can greatly shorten the construction time, improve safety, and save the high cost of high-altitude anti-corrosion operations.

[0030] Furthermore, in step S3, there are multiple lightweight prefabricated base plates, which are sequentially hoisted into the tower by the tower crane, and the multiple lightweight prefabricated base plates are spliced ​​together between the bottom ends of the two truss side beams.

[0031] The beneficial effect of adopting the above technical solution is that the lightweight precast base slab is installed by segmented hoisting, which makes the hoisting and installation of the lightweight precast base slab simpler and easier to carry out construction operations.

[0032] Furthermore, when installing the cross brace top rod in step S4, the cross brace top rod needs to be arranged obliquely between the top ends of the two truss side beams.

[0033] The beneficial effect of adopting the above technical solution is to improve the stability of the two truss side beams after construction. Attached Figure Description
