Description

一种矿砂船压载舱集成式检验通道及其搭建方法 技术领域
本发明涉及船舶建造领域，具体涉及矿砂船的压载舱集成式检验通道及其搭建方法。
背景技术
在矿砂船压载舱的设计中，为了满足对压载舱船体结构进行全面近观检查和板材测厚的要求，一般都是采用搭建传统的检验通道结构形式，这种结构形式为常规设计，而且该种结构形式也存在着诸多不利的因素：第一，采用搭建传统的检验通道结构形式，一般都是在压载舱内，通过在同一平面内增加扁钢、方钢等，并在上方搭设格栅、扶手的方法建立检验通道结构平台，一般都要在压载舱内才可安装结构，并且由于高度的原因会导致施工安装的难度加大和舱内二度施工造成的油漆破坏；第二，采用搭建传统的检验通道结构形式，既需要设置船体纵骨结构，又需要设置独立的检验通道平台，因此也浪费了一部分的制造材料，增加了制造成本，还增加了船舶的重量。如此以上两点，可以说既费时费工费材料，增加制造成本。
发明内容
为解决现有技术中大型船舶的内部检验通道搭建困难且浪费材料的缺陷，本发明的目的在于提供一种利用船舶的纵骨结构、减少搭建量的集成式检验通道结构及搭建方法。
为达到以上目的，本发明采取的技术方案为：
一种矿砂船压载舱集成式检验通道，包括舷侧外板、外板检验通道平台、压载舱水密舱壁、检验通道连接平台、内纵壁检验通道平台、内纵壁、检验通道平台支撑肘板，所述外板检验通道平台垂直焊接于舷侧外板内壁，所述内纵壁检验通道平台垂直焊接于内纵壁的内壁上，所述检验通道连接平台垂直焊接于压载舱水密舱壁，所述检验通道连接平台的两端连接外板检验通道平台和内纵壁检验通道平台，所述检验通道连接平台、外板检验通道、内纵壁检验通道平台为加宽的纵骨，所述检验通道连接平台、外板检验通道平台、内纵壁检验通道平台的底部由多个间隔设置的支撑肘板支撑，所述支撑肘板焊接于对应的压载舱水密舱壁、舷侧外板以及内纵壁。
进一步地，所述支撑肘板为梯形板，所述支撑肘板的上、下侧面分别焊接于加宽的纵骨以及其下方的纵骨。
进一步地，所述检验通道连接平台与外板检验通道平台、内纵壁检验通道平台位于同一平面，且连接的拐角处安装有直角补强板。
该矿砂船压载舱集成式检验通道的搭建方法，包括以下步骤：
(1)将舷侧外板、外板检验通道平台、压载舱水密舱壁、检验通道连接平台、内纵壁检验通道平台、内纵壁、检验通道平台支撑肘板按放样尺寸1：1进行数控下料；
(2)以舷侧外板一面为胎架基准面，确定外板检验通道平台的位置，建造加宽的纵骨代替原纵骨作为外板检验通道平台，以内纵壁一面为胎架基准面，确定外板检验通道平台的位置，建造加宽的纵骨代替原纵骨作为内纵壁检验通道平台；
(3)在安装好舷侧外板和内纵壁之后，将外板检验通道平台定位焊接安装在舷侧外板内壁，并在外板检验通道平台的底部等间距焊接多个支撑肘板，支撑肘板的三条侧边分别与舷侧外板、外板检验通道平台以及外板检验通道平台底部的纵骨焊接固定；将内纵壁检验通道平台定位安装在内纵壁上，并在内纵壁通道平台的底部等间距焊接多个支撑肘板，支撑肘板的三条侧边分别与内纵壁、内纵壁检验通道平台以及内纵壁检验通道平台底部的纵骨焊接固定；
(4)以压载舱水密舱壁一面为胎架基准面，建造加宽的纵骨代替原纵骨作为检验通道连接平台；
(5)在定位安装好的压载舱水密舱壁外侧，将检验通道连接平台焊接安装在压载舱水密舱壁上，检验通道连接平台的两端分别与同层的外板检验通道平台以及内纵壁相检验通道平台的侧面平齐，并在检验通道连接平台的底部等间距焊接多个支撑肘板，支撑肘板的三条侧边分别与压载舱水密舱壁、检验通道连接平台以及外检验通道连接平台底部的纵骨焊接固定；
(6)在检验通道连接平台与外板检验通道平台、内纵壁检验通道平台的连接处的内拐角焊接安装直角补强板。
采取以上技术方案后，本发明的有益效果为：
利用矿砂船压载舱结构形式的特殊性，改变传统的检验通道由舾装搭设平台安装的方法，改为借助外板及内纵壁纵骨的宽度设计检验通道，将纵骨与检验通 道平台合二为一使用，采用这种检验通道的结构形式，不仅可以节省建造周期，同时还降低了施工难度。
在船舶设计过程中，将船舶原有纵骨结构兼做检验通道平台使用，不仅有利于增加船舶整体的结构强度，还将工序前移至分段建造过程中完成检验通道平台的施工，减少了后期舾装搭建检验通道的工作量，降低后续由于高度原因造成的难度和舱内二度施工造成的油漆破坏，有效提高了生产效率；且在保证船舶结构强度的前提下，此方法减少了部分结构，降低了重量，降低了制造成本。

该矿砂船压载舱集成式检验通道的搭建方法如下：
(1)将舷侧外板7、外板检验通道平台1、压载舱水密舱壁9、检验通道连接平台2、内纵壁检验通道平台3、内纵壁8、支撑肘板5按放样尺寸1：1进行数控下料；
(2)以舷侧外板7一面为胎架基准面，确定外板检验通道平台1的位置，建造加宽的纵骨代替原纵骨作为外板检验通道平台1，以内纵壁8一面为胎架基准面，确定外板检验通道平台的位置，建造加宽的纵骨代替原纵骨作为内纵壁检验通道平台3；
(3)在安装好舷侧外板7和内纵壁8之后，将外板检验通道平台1定位焊接安装在舷侧外板7内壁，并在外板检验通道平台1的底部等间距焊接多个支撑肘板5，支撑肘板5的三条侧边分别与舷侧外板7、外板检验通道平台1以及外板检验通道平台底部的纵骨焊接固定；将内纵壁检验通道平台3定位安装在内纵壁8上，并在内纵壁通道平台3的底部等间距焊接多个支撑肘板5，支撑肘板5的三条侧边分别与内纵壁8、内纵壁检验通道平台3以及内纵壁检验通道平台底部的纵骨焊接固定；
(4)以压载舱水密舱壁9一面为胎架基准面，建造加宽的纵骨代替原纵骨作为检验通道连接平台2；
(5)在定位安装好的压载舱水密舱壁9外侧，将检验通道连接平台2焊接安装在压载舱水密舱壁9上，检验通道连接平台2的两端分别与同层的外板检验通道平台1以及内纵壁相检验通道平台3的侧面平齐，并在检验通道连接平台的底部等间距焊接多个支撑肘板5，支撑肘板5的三条侧边分别与压载舱水密舱壁9、检验通道连接平台2以及外检验通道连接平台底部的纵骨焊接固定；
(6)在检验通道连接平台2与外板检验通道平台1、内纵壁检验通道平台3的连接处的内拐角焊接安装直角补强板10。
本技术方案将检验通道与纵骨兼做使用，不仅有利于船舶整体的结构强度还可提高生产效率、降低材料损耗。
