Abstract
The utility model relates to a marine ceiling access door, comprising a compound rock wool ceiling (1) and an access door board (3), wherein the compound rock wool ceiling (1) is provided with a doorhole; the periphery of the door hole is embedded with a rubber board skeleton (1.1) which is externally coated with a door frame (2) and a door pressing frame (4); the periphery of the back surface ofthe access door board (3) is respectively compounded with a smoke-proof strip (5); the door pressing frame (4) comprises a rear cross pressing frame (4.1) which is arranged at the rear side of the rubber board skeleton (1.1); one side of the rear cross pressing frame (4.1), which is separated from the access door board (3), bends forward by 180 degrees and then is closely compounded on the back surface of the rear cross pressing frame (4.1); one side of the rear cross pressing frame (4.1), close to the access door board (3), bends forward by 90 degrees so as to form a side pressing frame (4.2); and the side pressing frame (4.2) is arranged beside the rubber board skeleton (1.1). The marine ceiling access door has high fire-proofing grade and the door frame position does not have bur.
Description
(1) technical field
The utility model relates to a kind of ceiling access door for ships.Be used on the composite rock wool plate of the overhead that needs maintenance.Belong to technical field of ships.
(2) background technology
For ease of maintenance, access door is installed as on the top ceiling of composite rock wool plate by portion belowdecks usually.Top ceiling has strict fire safety rules requirement.Adorned the whole fire-protection rating that still will reach the composite rock wool plate behind the access door.Before the utility model was made, ceiling access door for ships in the past had the following disadvantages:
1, owing to around the maintenance door-plate anti-plume is not set, the fiery cigarette that burning produces can be gone out from the clearance leakage between maintenance door-plate and the doorframe, so fire endurance rating is low, its fire resistance out of reach B15 level.
2, because the door opening place of composite rock wool plate top ceiling is not provided with a press box, door opening has been sawed later doorframe place and has been had the burr generation, causes the ceiling access door for ships overall aesthetics poor.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of fire endurance rating height, door-plate opening part can not to have the ceiling access door for ships of burr.
The purpose of this utility model is achieved in that a kind of ceiling access door for ships, comprise composite rock wool plate top ceiling and maintenance door-plate, offer a door opening on the described composite rock wool plate top ceiling, be equipped with the offset plate skeleton around the described door opening, described maintenance door-plate one side is hinged by the offset plate skeleton of hinge and described doorframe one side, described offset plate skeleton is coated with doorframe and door press box, described doorframe comprises front transverse frame, this front transverse frame is arranged at described offset plate skeleton front side, this front transverse frame closely is compounded in the front transverse frame back side after bending 180 ° backward away from the one side of overhauling door-plate, this front transverse frame bends 90 ° of formation side frames backward near one side of maintenance door-plate, this side frame is arranged at the side of described maintenance door-plate, the back of this side frame forms rear transverse frame for 90 ° to the direction bending near the maintenance door-plate, this rear transverse frame closely is compounded in the rear transverse frame back side after bending 180 ° forward away from one side of described composite rock wool plate top ceiling, and this rear transverse frame is arranged at around the back side of described maintenance door-plate; All be compounded with anti-plume around the back side of described maintenance door-plate, described anti-plume is arranged at the front side of described rear transverse frame; Described door press box comprises the horizontal press box in back, the horizontal press box in this back is arranged at described offset plate skeleton rear side, the horizontal press box in this back closely is compounded in the horizontal press box back side, back after bending 180 ° forward away from the one side of overhauling door-plate, the horizontal press box in this back bends 90 ° of formation side pressure frames forward near one side of maintenance door-plate, and this side pressure frame is arranged at the side of described offset plate skeleton.
Compare with existing ceiling access door for ships, the utlity model has following advantage:
1, owing to around the doorframe of described access door, all is stained with anti-plume, should anti-plume be intumescent, meeting self inflation after the burning, the burning chance can expand nearly 25 times when hot, and the gap between maintenance doorframe and the door leaf is blocked, and flame can't pass, do not allow cigarette leak out, good seal performance, so fire endurance rating height, its fire resistance can reach the B15 level.
2, owing to side and rear side at described composite rock wool plate top ceiling door opening are provided with a press box, door opening has been sawed later doorframe place does not have the burr generation, and the ceiling access door for ships overall aesthetics is good.
