Problems solved by technology

[0008] However, in the general assembly process, the upper and lower decks are assembled in multiple sections in the width direction, and there is no strong structure on the four sides of the section to support the upper and lower sides. However, it is often difficult to assemble from the section to form a complete section. long natural period

Embodiment 1

[0029] see Figure 1-6 ,本实施例提供了大型邮轮薄板总段内部临时支撑方法,包括如下步骤:

[0030] 中间全宽型甲板分段的左右两侧:因为外板分段参与总组较晚,中间全宽型甲板分段从下往上总组成多层甲板总段,所以该分段左右两侧长时间处于自由状态,在结构特点方面,往往前后左右8m范围内无立柱2、舱壁、围壁结构进行上下支撑,且该区域的薄板甲板板架5相对较弱,设置内部临时支撑进行上下连接,确保上方甲板不会沉降,直到外板结构总组完成后,才进行临时支撑拆除。

[0031] 带外板半宽型分段9之间:某类总段的多层甲板,都采取这种划分方式,单层甲板的左右分段之间,甲板面下方的结构自身支撑结构可能较少, 在后总组分段的总组之前,以总组的分段的船中位置处于自由状态,必须设置必要的内部临时支撑进行上下连接,直到左右分段都总组完成后,才进行临时支撑 tear down.

[0032] 甲板面大型舾装的下方:部分大型舾装设计在分段左右首尾的自由边位置,带来甲板沉降问题并影响舾装准确安装,在大型舾装的甲板下方,设置必要的内部临时支撑进行上下连接,直到总组后期或者船坞阶段大型舾装设备四周具备上下强结构,才进行临时支撑拆除。

[0033] 总段首尾端面:总段首尾端面往往没有完整的全幅面舱壁结构,或者立柱2结构数量不足,因薄板总段采用大型吊车进行船坞吊装,其吊点往往距离首尾端面有一定距离,加上总段层数较多,为了确保总段首尾端面的整体刚度,并避免变形给船坞总段之间合拢作业带来困难,必须确保保证首尾端面的结构精度,在首尾端面各层甲板之间,设置必要的内部临时支撑,直到总段船坞吊装结束,才进行临时支撑拆除。

[0034] 支撑结构均选用圆管15型材,且圆管15的两端各设置有四块肘板14用于上下连接焊接,仅仅肘板14连接,圆管15不连接。

[0035] 圆管15型材直径60mm-100mm,壁厚6-10mm,φ80mm×8mm圆管15 2.5m长,其重量35kg,相比其他常用建造用型材,重量轻了接近40%,这样拆除后更方便从邮轮结构内部运输到外部进行回收,提高作业效率,否则太重,往往进行切断进行运输,造成整根回收不便,同时,太重或者进行切断,可能在拆除及运输过程中碰撞薄板结构,造成破坏。

Abstract

According to a large cruise ship sheet block internal temporary supporting method, toggle plates and round pipes are connected to form a supporting structure, and the supporting structure is preset ateach installation position of a ship body, so that the precision between an upper deck and a lower deck can be ensured while the stability of upper supporting and lower supporting is ensured, smoothconstruction is ensured; and, through repeated utilization of the toggle plates, Waste of consumables can be effectively reduced, and efficient operation of supporting work can be guaranteed under thecondition that the cost is controlled.

Description

technical field [0001] 本发明涉及大型邮轮建造支撑相关技术领域,具体为大型邮轮薄板总段内部临时支撑方法。 Background technique [0002] 大型邮轮是薄板船体结构,其主要结构框架由外板板架、甲板板架、主竖区横舱壁板架、立柱组成,还有部分内部纵横围壁板架,甲板板架,主要8mm以下厚度的钢板、小规格球扁钢和较为稀疏的T-beam纵横梁组成,大型邮轮一般有十五六层以上甲板,是主要的水平承重水平板架,主竖区横舱壁板架,一般在船的首尾方向间隔40m左右,立柱,一般在间隔一档T-beam处连接上下两层甲板,所以,各层甲板之间,依靠外板板架、主竖区横舱壁板架、立柱、部分内部纵横围壁板架进行支撑。 [0003] 大型邮轮的船宽一般在40m左右,根据邮轮结构型式和船厂薄板分段流水线,且分段宽度应小于流水线单个工位最大长度36m的建造特点,基于高效高质量建造需求,一般对邮轮结构采取如下分段划分及建造方式: [0004] 各层甲板之间,上下相互划分为不同的分段; [0005] 单层甲板内,划分为中间全宽型甲板分段、外板分段,或者划分为左右两只带外板半宽型分段。 [0006] 对于包含阳台外板的甲板,必定会基于外板结构的专业化建造要求,将外板与中间甲板划分开。 [0007] 根据邮轮结构及舾装特点,以及船坞吊车起重能力,一般将3-5层甲板组成总段,在船坞搭载前进行总组建造。根据总段的结构建造顺序,一般是一层一层甲板分段依次总组,最后总组外板分段。 [0008] 而在总组过程中,上下层甲板之间在宽度方向分多个分段先后总组,分段四边没有强结构进行上下支撑,而从该分段开始总组到形成完整总段往往具有较长的固有周期。因此,必须设置内部临时支撑以辅助总组建造,直至上下甲板之间在宽度方向已具备完整的船体结构,以确保足以上下支撑,才能确保上下甲板之间精度,并确保建造顺利进行。 Contents of the invention [0009] 本发明的目的在于提供大型邮轮薄板总段内部临时支撑方法,以解决上述背景技术中提出的问题。 [0010] 为实现上述目的,本发明提供如下技术方案:大型邮轮薄板总段内部临时支撑方法,具体包括如下步骤: [0011] T1、中间全宽型甲板分段的左右两侧:...
