The advantages of the present invention are: the cable laying method of the hull cab of the present invention is installed on the front of the cab deck through the cable trough, which can avoid damage to the cables, and is convenient for construction and maintenance. In addition, a fireproof layer is set on the back of the cab deck to enhance fire performance.

Description

A method for laying cables in a hull bridge

technical field

The invention relates to the field of ship manufacturing, in particular to a cable laying method for a ship cab.

Background technique

Ship electrical cable laying is a key link in ship electrical installation. The quality of the cable laying process directly affects whether the ship's power distribution system can work normally and safely, and whether the electrical equipment can operate effectively and reliably.

There are two structures for cable laying in the ship's cab. The first one is shown in Figure 1. The cable 1 passes through the deck 2 of the cab and is hidden on the back of the deck 2 of the cab. The disadvantage of this laying structure is that the cable 1 is exposed to the In the area of the lower layer of the cab, the cables will be burned if the lower layer catches fire, resulting in failure of the cab equipment control or signal; the second type is shown in Figure 2, in order to avoid cable exposure, a cable bracket 3 is added on the back of the cab deck 2, so that The disadvantage of protecting the cable 1 is that since there are many horizontal and vertical profiles on the back of the deck 2 of the cab, and the air ducts and cable brackets are staggered vertically and horizontally, it is difficult to construct additional structures, and it is also not conducive to maintenance.

Contents of the invention

The technical problem to be solved by the present invention is to provide a cable laying method for the hull bridge with a simple construction method and improved insulation and fireproof performance of the cables.

In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a method for laying cables in the cab of a hull. The back of the deck is covered with a fireproof layer.

Further, the specific steps of the method are as follows:

(1) Cable laying: first install the cable trough on the deck of the cab, and then install the cables in the cable trough. After the cable installation is completed, install the cable trough cover at the notch of the cable trough;

(2) Laying high-level layers: Lay soundproof rock wool layer, light deck covering layer and deck covering layer on the cab deck around the cable trough in sequence, and keep the upper end surface of the deck covering layer flush with the upper end surface of the cable trough;

(3) Lay the floor: Lay the floor above the high-rise and the cable trough. When laying the floor, first lay the leveling dressing layer, and then lay the floor above the leveling dressing layer;

(4) Laying fireproof layer: Lay ceramic wool on the back of the cab deck in the area where the cable trough is located and within 450mm on both sides of the area where the cable trough is located.

Further, the lightweight deck covering layer may be expanded perlite.

The advantages of the present invention are:

(1) The cable laying method of the hull cab of the present invention is installed on the front of the cab deck through the cable trough, which can avoid cable damage and is convenient for construction and maintenance;

(2) The laying method of the present invention is specifically divided into laying cable troughs, laying high-rise floors, laying floors, and laying fireproof layers. The high-rise layers use sound-insulating rock wool layers, lightweight deck covering layers, and deck covering layers, which strengthen the sound insulation effect. Does not affect the weight of the empty ship, and the cost is low; the fireproof layer is made of ceramic wool, covering the area where the cable duct is located and the area within 450mm on both sides of the area where the cable duct is located, with good fire resistance;

(3) The lightweight deck covering layer can be expanded perlite, which has low thermal conductivity and enhances the thermal insulation performance of high-rise buildings.

detailed description

As shown in Figure 1, the present invention discloses a method for laying cables 1 in a hull cab. The method is that the cables 1 are installed on the front of the cab deck 2 through the cable trough 4, and on the back of the cab deck 2 in the area where the cable trough 4 is located. Lay a fireproof layer.

The specific steps of the above method are as follows:

The first step is to lay cables: first install the cable groove 4 on the cab deck 2, then install the cable 1 in the cable groove 4, and when the cable 1 is installed, install the cable groove cover 5 at the notch of the cable groove 4;

The second step is to lay high-level layers: on the cab deck 2 around the cable trough 4, a sound-insulating rock wool layer 6, a lightweight deck covering layer 7 and a deck covering layer 8 are successively laid, and the lightweight deck covering layer adopts expanded perlite. The upper end surface of the deck coating layer 8 is flush with the upper end surface of the cable duct 4;

The third step is to lay the floor: lay the floor 9 above the upper level and the cable duct 4. When laying the floor 9, first lay the leveling dressing layer 10, and then lay the floor 9 above the leveling dressing layer 10;

The fourth step is to lay the fireproof layer: lay ceramic wool 11 on the back of the cab deck 2 in the area where the cable duct 4 is located and within 450 mm on both sides of the area where the cable duct 4 is located.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above. Those skilled in the industry should understand that the present invention is not limited by the above-mentioned embodiments. What are described in the above-mentioned embodiments and the description only illustrate the principle of the present invention.
