Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to a modular installation method for a floor drain on a composite material deck and a modular floor drain structure. Background Art

[0002] Traditional decks are made of steel, and floor drains are also steel structures. Therefore, floor drains are typically welded to the deck. However, to reduce ship weight, some ship decks are made of composite materials. However, welding processes are not suitable for the mechanical properties of composite decks, so floor drains cannot be directly welded to the deck. Summary of the Invention

[0003] In view of this, the present invention provides a modular installation method for a floor drain on a composite material deck and a modular floor drain structure, so as to solve the problems existing in the above-mentioned background technology.

[0004] A modular installation method for a floor drain on a composite deck comprises the following steps:

[0005] S1, pre-treat the leak opening on the composite deck;

[0006] S2, welding and fixing the steel flange ring to the outer wall of the floor drain at a position a first distance away from the upper edge of the outer wall;

[0007] S3, pre-embed and fix the fiberglass flange ring in the leaking hole of the composite deck;

[0008] S4, place the floor drain with welded steel flange ring into the leaking hole of the composite deck;

[0009] S5, rotate the floor drain so that the bolt holes on the steel flange ring are aligned with the bolt holes on the fiberglass flange ring, and then use bolts to lock the steel flange ring and the fiberglass flange ring together;

[0010] S6. Apply structural adhesive to the surface of the steel flange ring so that the upper surface of the structural adhesive after solidification is flush with the upper surface of the composite deck.

[0011] Preferably, in step S2, the steel flange ring is fixed on the outer wall of the floor drain at a position 5 mm to 10 mm away from the upper edge of the outer wall.

[0012] Preferably, in step S2, the specific steps of pre-embedding and fixing the fiberglass flange ring in the leaking port of the composite material deck in step S3 are:

[0013] According to the outer diameter of the fiberglass flange ring, a countersunk hole is opened outward around the water leakage hole of the composite deck but does not penetrate the composite deck plate body;

[0014] Use structural adhesive to embed and fix the fiberglass flange ring in the countersunk hole of the composite deck;

[0015] After the structural adhesive solidifies, step S4 is performed.

[0016] Preferably, the structural adhesive is evenly filled in the gap between the fiberglass flange ring and the composite material deck by pouring, so as to pre-embed and fix the fiberglass flange ring in the countersunk hole of the composite material deck.

[0017] Preferably, when executing step S6, structural adhesive may be filled into the gap between the steel flange ring and the composite material deck.

[0018] A modular floor drain structure installed using the method includes a floor drain, a fiberglass flange ring, and a steel flange ring. A composite deck is provided with a through leakage opening and non-through countersunk holes extending outward from the leakage opening. The floor drain is arranged in the leakage opening of the composite deck, the fiberglass flange ring is arranged in the countersunk holes of the composite deck, the steel flange ring is stacked on the fiberglass flange ring and fixed to the fiberglass flange ring by bolts, and the steel flange ring is welded to the outer wall of the floor drain. Structural adhesive is poured into the surface of the steel flange ring and the gap between the fiberglass flange ring and the composite deck.

[0019] Preferably, the gap between the steel flange ring and the composite material deck is also filled with structural adhesive.

[0020] The beneficial effects of the present invention are:

[0021] 1. The present invention pre-buries a fiberglass flange ring in the composite material deck, utilizes the fiberglass flange ring to adapt to the composite material properties of the deck, welds and fixes the steel flange ring on the floor drain, connects the steel flange ring and the fiberglass flange ring with bolts, and fills the gaps between the steel flange ring, the fiberglass flange ring, the composite material deck, and the floor drain with structural adhesive, thereby forming a multiple sealing barrier. This effectively solves the problem of being unable to install a metal floor drain on a composite material deck, and also solves the sealing problem of the metal floor drain, significantly reducing the probability of leakage.

[0022] 2. The present invention adopts a composite design of connecting a fiberglass flange ring and a steel flange ring. The steel flange ring can improve the structural strength of the connection structure between the floor drain and the composite deck, avoiding deformation of the connection between the composite deck and the floor drain due to external forces and other factors, which may cause the seal to fail. It can effectively ensure the sealing life, reduce the probability of leakage, and increase the service life of the floor drain. BRIEF DESCRIPTION OF THE DRAWINGS
