A kind of hull driver's cabin cable laying method
Technical field
The present invention relates to shipbuilding field, particularly a kind of hull driver's cabin cable laying method.
Background technology
Marine electrical equipment cable laying is the key link during marine electrical equipment is installed, and whether the quality of cable laying technique directly has influence on ship power distribution system and can normally, safely work, and whether electric equipment effectively, reliably operates.
When ship-handling house cable lays, there are two kinds of structures, the first as shown in Figure 1, cable 1 is hidden in flying bridge deck 2 back side through flying bridge deck 2, the shortcoming of this kind of laying structure is, cable 1 is exposed to the region of driver's cabin lower floor, can burn cable after lower floor catches fire, cause bridge equipment control or signal malfunctioning; The second as shown in Figure 2; in order to avoid cable exposes; adopt and increase cable tray 3 at flying bridge deck 2 back side; thus cable 1 is protected; its shortcoming is: because the horizontal longitudinal profile in flying bridge deck 2 back side is many; and airduct and cable tray etc. are staggered in length and breadth, increase structure and be difficult to construction, be also unfavorable for maintenance.
Summary of the invention
It is simple and improve the insulation of cable and the hull driver's cabin cable laying method of fire protecting performance that the technical problem to be solved in the present invention is to provide a kind of construction method.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of hull driver's cabin cable laying method, its innovative point is: described method is that cable is arranged on flying bridge deck front by cable trough, and at the back side of cable trough region flying bridge deck paving fireprotection layer.
Further, the concrete steps of described method are as follows:
(1) cabling: first installing cables groove on flying bridge deck, then cable is arranged in cable trough, when after cable installation, at the notch place installing cables groove lid of cable trough;
(2) contour level is laid: the flying bridge deck around cable trough is laid successively sound insulation rock wool layer, light deck dressing layer and deck composition layer, the upper surface of deck composition layer and the upper surface of cable trough keep flushing;
(3) laying floor: laying floor above contour level and cable trough, first lays levelling dressing layer during laying floor, then laying floor above levelling dressing layer;
(4) fireprotection layer is laid: lay ceramic wool at the back side of the flying bridge deck of cable trough region and both sides, cable trough region 450mm inner region.
Further, described light deck dressing layer can be expanded perlite.
The invention has the advantages that:
(1) hull driver's cabin cable laying method of the present invention, is arranged on flying bridge deck front by cable trough, cable can be avoided impaired, and construction and maintenance are conveniently;
(2) laying method of the present invention is specifically divided into cabling groove, laying contour level, laying floor and lays fireprotection layer, contour level adopts sound insulation rock wool layer, light deck dressing layer and deck composition layer, it reinforces soundproof effect, do not affect the weight of clean ship, and cost is low; Fireprotection layer adopts ceramic wool, and overlay area comprises cable trough region and both sides, cable trough region 450mm inner region, and fire protecting performance is good;
(3) light deck dressing layer can be expanded perlite, and the thermal conductivity of expanded perlite is low, strengthens the heat-insulating property of contour level.

Embodiment
As shown in Figure 1, the invention discloses a kind of hull driver's cabin cable 1 laying method, the method is that cable 1 is arranged on flying bridge deck 2 front by cable trough 4, and at the back side of cable trough 4 region flying bridge deck 2 paving fireprotection layer.
The concrete steps of said method are as follows:
The first step, cabling: first installing cables groove 4 on flying bridge deck 2, then cable 1 is arranged in cable trough 4, when after cable 1 installation, at the notch place installing cables groove lid 5 of cable trough 4;
Second step, lay contour level: the flying bridge deck 2 around cable trough 4 is laid successively sound insulation rock wool layer 6, light deck dressing layer 7 and deck composition layer 8, light deck dressing layer adopts expanded perlite, and the upper surface of deck composition layer 8 keeps flushing with the upper surface of cable trough 4;
3rd step, laying floor: laying floor 9 above contour level and cable trough 4, first lays levelling dressing layer 10 during laying floor 9, then laying floor 9 above levelling dressing layer 10;
4th step, lays fireprotection layer: lay ceramic wool 11 at the back side of the flying bridge deck 2 of cable trough 4 region and both sides, cable trough 4 region 450mm inner region.
