Description

Novel method for building ocean platform block

Technical Field

The invention relates to a novel method for building an ocean platform block.

Background

The main structure of the ocean platform block generally comprises 3-5 layers of decks, each layer of deck is generally formed by welding and splicing a plurality of deck plates, a room formed by welding upright posts, tie bars, wall skins and the like between an upper layer of deck and a lower layer of deck, equipment in the room and other structures are formed.

The conventional construction method of the ocean platform block comprises the following steps: prefabricating each deck plate of the lower layer, spraying the deck plates, and welding and splicing a plurality of lower deck plates into a lower deck; respectively spraying the upright post, the lacing wire, the wall skin and the like; and welding and installing the upright posts, the tie bars, the wall coverings and the like to form a room. Then, each deck plate on the upper layer is prefabricated, the deck plates are sprayed, the deck plates are hoisted in place and welded with the upright posts, the tie bars, the wall coverings and the like, the deck plates on the upper layer are welded into an upper deck in sequence, and finally paint repair is carried out.

The defects of the prior art are as follows: the simultaneous work on the deck has a large amount of cross work, the building period of the block is long, the high-altitude work is more, the safety is poor, the spraying frequency is more, the work efficiency is low, the repetitive work is more, the paint repairing work amount is large, and the like.

Disclosure of Invention

The invention provides a novel method for building an ocean platform block, which can reduce the spraying times and the paint replenishing amount when the ocean platform block is built.

In order to solve the technical problem, the invention provides a novel method for building an ocean platform block, which is realized by the following steps:

(1) prefabricating an upper deck and a lower deck of a room;

(2) welding the upright posts, the tie bars and the wall skins with the upper deck and the lower deck to form an integral room;

(3) transporting the room to a spraying workshop for integral spraying;

(4) hoisting the assembled room in place;

(5) repeating the steps (1) to (4) until the number of the prefabricated rooms meets the design requirement of the platform;

(6) and welding all the hoisted rooms in place to complete the construction of the ocean platform block.

Furthermore, the number of the prefabricated rooms is 3, so that the design requirement of the platform can be met.

The invention has the technical effects that: (1) the original technical proposal is that lower deck plates are prefabricated and sprayed, and upright posts, lacing wires, wall coverings and the like on the lower deck plates are respectively sprayed and installed; and then spraying and installing an upper deck plate, and finally performing paint repair. The invention adopts the scheme of prefabricating rooms in advance on land, integrally spraying and integrally hoisting, thereby greatly improving the working efficiency, saving the construction period and reducing the spraying times and the paint replenishing amount; (2) the original technical scheme has the disadvantages of more high-altitude operation, more work for building scaffolds, and easy generation of safety and quality problems. The invention can greatly reduce overhead operation and cross operation, thereby greatly improving the safety and the reliability.

Detailed Description

The present invention is further described with reference to the following drawings and specific examples so that those skilled in the art can better understand the present invention and can practice the present invention, but the examples are not intended to limit the present invention.

Embodiment, as shown in fig. 1 to 6, the present invention discloses a new method for constructing ocean platform blocks, and the number of rooms constructed by the method of the present invention is determined according to actual design requirements. In this embodiment, three rooms are taken as an example, and each step is implemented as follows:

the first step is as follows: and prefabricating the first deck 1, the fourth deck 4, the upright post 7, the tie bar 8 and the wall skin 9.

The second step is that: and welding the first deck 1, the second deck 2, the upright post 7, the tie bar 8, the wall skin 9 and the temporary support 10 to form a room I.

The third step: and transporting the whole room to a spraying workshop for integral spraying.

The fourth step: and hoisting the whole room in place.

The fifth step: and prefabricating the second deck 2, the fifth deck 5, the upright post 7, the tie bar 8 and the wall skin 9.

And a sixth step: and welding the second deck 2, the fifth deck 5, the upright post 7, the tie bar 8, the wall skin 9 and the temporary support 10 to form a second room.

The seventh step: and integrally transporting the room II to a spraying workshop for integral spraying.

Eighth step: and integrally hoisting the second room in place and welding and assembling the second room with one side of the first room.

The ninth step: prefabricating a third deck 3, a sixth deck 6, a stand column 7, a tie bar 8, a wall skin 9 and a temporary support 10.

The tenth step: and welding the third plate 3, the sixth plate 6, the upright post 7, the tie bar 8, the wall skin 9 and the temporary support 10 to form a third room.

The eleventh step: and transporting the three rooms to a spraying workshop for integral spraying.
