Description
ВОДОНЕПРОНИЦАЕМЫЙ КОРПУС ПЛАВУЧИХ СООРУЖЕНИЙ WATERPROOF HOUSING OF FLOATING STRUCTURES
Изобретение относится к морской технике и касается конструирования корпуса судна или плавучего сооружения. The invention relates to marine engineering and for the construction of a ship's hull or floating structure.
Общеизвестно, что для обшивки корпуса плавучего средства обычно применяются такие жесткие материалы, как металл, дерево, полимеры, композиты из разных органических и неорганических компонентов. Корпусы существующих плавучих средств представляют собой жесткие конструкции, ударостойкость оболочки которых зависит от прочности применяемых материалов и толщины оболочки. Увеличение ударостойкости конструкции этих сооружений приводит к повышению их нежелательного веса, либо требует больше затратов материальных и энергических ресурсов для их построения и эксплуатации. Гибкая оболочка корпуса плавучих средств наблюдается только в изготовлении надувных лодок или лодок на воздушных подушках, выполненных в виде целого надувного баллона из резины или ткани поливинилхлорида. Но такая конструкция не может применена в изготовлении судов или больших плавучих сооружений, где требуются большая прочность и определенный внешний вид. It is well known that rigid materials such as metal, wood, polymers, composites from various organic and inorganic components are usually used for sheathing a body of a floating craft. The hulls of existing floating equipment are rigid structures, the impact resistance of the shell of which depends on the strength of the materials used and the thickness of the shell. An increase in the impact resistance of the construction of these structures leads to an increase in their undesirable weight, or requires more material and energy resources for their construction and operation. The flexible hull of the hull of floating craft is observed only in the manufacture of inflatable boats or air cushion boats made in the form of a whole inflatable balloon made of rubber or PVC fabric. But such a design cannot be applied in the manufacture of ships or large floating structures, where greater strength and a certain appearance are required.
Задачей, решаемой данным изобретением, является уменьшение массы корпуса плавучего средства за счет применения эластичных и прочных полимерных материалов в обшивке оболочки, основывающейся на металлическом каркасе, причем обеспечиваются прочность и внешний вид по заданной архитектуры корпуса. The problem solved by this invention is to reduce the mass of the hull of the floating means due to the use of elastic and durable polymeric materials in the shell casing based on the metal frame, and strength and appearance according to the given architecture of the hull are provided.
Поставленная задача достигается тем, что в корпусе выполнены подушки, сделанные Из полимерных и их композитных материалов и выстроенные на основе металлического каркаса. Каждая подушка монтируется в ячейке многоугольной формы, в частном случае четырехугольной формы, выполненной в результате разделения наружной поверхности корпусного каркаса пересекающимися на одном уровне металлическими арматурами прямоугольного сечения, в частном случае продольными и поперечными, состоящими из лежащих арматур, закрепленных снаружи к каркасным опорам (для ' судна - шпангоутам), и стоящих арматур, перпендикулярно соединенных сваркой вдоль и посредине широкой стороны лежащих арматур. Подушка состоит из боковых стен, внутренней и внешней пластин. Пластины, закрывающие ячейки внутри и создающие внутренний слой оболочки корпуса, изготовлены из прочных материалов с целью противостояния силе изгиба и герметично закреплены к лежащим арматурам; а пластины, закрывающие ячейки снаружи и создающие внешний слой оболочки корпуса, изготовлены из прочных материалов, либо из эластичных полимерных материалов, либо из прочных и эластичных материалов в виде многослойной пластины, герметично закреплены к плоской выступной поверхности рамок, образующихся полосами эластичного полимерного материала, покрывающими стоящие арматуры и служащими как боковые стены подушки. При необходимости полость подушек заполнена пористыми материалами или надувными камерами из легких эластичного полимерного материала с целью поддержания устойчивости внешнего слоя оболочки корпуса. The task is achieved in that the cushion is made in the body, made of polymer and their composite materials and built on the basis of a metal frame. Each pillow is mounted in a cell of a polygonal shape, in the particular case of a quadrangular shape, made as a result of dividing the outer surface of the casing by intersecting metal reinforcement of rectangular cross section, in the particular case of longitudinal and transverse, consisting of lying reinforcements fixed outside to the frame supports (for 'of the vessel - frames), and standing reinforcement, perpendicularly connected by welding along and in the middle of the wide side of the lying reinforcement. The pillow consists of side walls, inner and outer plates. The plates covering the cells inside and creating the inner layer of the shell are made of durable materials in order to withstand the bending force and hermetically fixed to lying fittings; and the plates that cover the cells on the outside and create the outer layer of the shell membrane are made of durable materials, either of elastic polymer materials, or of strong and elastic materials in the form of a multilayer plate, hermetically fixed to the flat protruding surface of the frames formed by strips of elastic polymer material covering standing armatures and serving as side walls of the pillow. If necessary, the cavity of the pillows is filled with porous materials or inflatable chambers made of lightweight elastic polymer material in order to maintain the stability of the outer layer of the shell casing.
Малой удельной плотностью и водонепроницаемостью полимерных материалов являются позитивные характеристики для изготовления легковесного корпуса плавучего средства. Высокий предел упругости, а также высокий предел прочности на растяжение и сжатие эластичного полимерного материала обеспечивают конструкции противостояние разным действующим силам, при этом эластичные подушки рассеивают действующие силы на все направления, снижая локальное давление на поверхности корпуса. Сеть металлических арматур прямоугольного сечения, соединенных между собой перпендикулярно в виде лежащих и стоящих полос, обеспечивает продольную и поперечную прочность корпуса. Разделение поверхности корпуса на ячейки дает удобный способ формированию его внешнего архитектурного вида. The low specific gravity and water resistance of polymeric materials are positive characteristics for the manufacture of a lightweight hull of a floating vessel. A high elastic limit, as well as a high tensile and compressive strength of the elastic polymer material provide the structure withstanding different acting forces, while the elastic cushions disperse the acting forces in all directions, reducing local pressure on the housing surface. A network of metal reinforcement of rectangular cross-section, connected to each other perpendicularly in the form of lying and standing strips, provides longitudinal and transverse strength of the housing. Dividing the surface of the housing into cells provides a convenient way to form its external architectural appearance.
Сущность изобретения поясняется рисунком, на котором представлен фрагмент поперечного сечения корпуса плавучего сооружения. The invention is illustrated in the figure, which shows a fragment of a cross section of the hull of a floating structure.
Корпус включает каркасные опоры (для судна - шпангоуты) 1, на которых располагаются лежащие на широкой стороне арматуры 2 прямоугольного сечения, вдоль и посредине их обратной широкой стороны соединены сваркой перпендикулярно стоящие арматуры 3 того же сечения; пересечением этих арматур на одном уровне образуется сеть ячеек многоугольной формы, полости этих ячеек заполнены пористыми материалами или воздушными камерами 4 и ограничены внутренними пластинами 5 и внешними пластинами 6, при этом внешние пластины 6 закреплены к полосам 7 из эластичного полимерного материала, опирающимся на стоящие арматуры 3; The hull includes frame supports (frames for the vessel) 1, on which are located the reinforcement 2 of rectangular cross section lying on the wide side, and the perpendicular standing reinforcement 3 of the same cross section is welded along and in the middle of their reverse wide side; the intersection of these fittings at one level forms a network of polygonal cells, the cavities of these cells are filled with porous materials or air chambers 4 and are limited by internal plates 5 and external plates 6, while the outer plates 6 are fixed to strips 7 of elastic polymer material, based on standing reinforcement 3;
Здесь и далее лежащим арматурам называется металлическая полоса прямоугольного сечения, которая крепится ее широкой стороной к какому-либо основанию; а стоящим арматурам называется металлическая полоса того же сечения, крепящаяся ее узкой стороной к какому-либо основанию. Изготовление предлагаемой конструкции корпуса сооружения осуществляется следующим образом. Hereinafter, the lying reinforcement is called a metal strip of rectangular cross section, which is fastened by its wide side to any base; and standing reinforcement is a metal strip of the same cross section, fastened with its narrow side to any base. The manufacture of the proposed structure of the building is as follows.
На каркасных опорах 1 закрепить сваркой или иным способом одинаковые по ширине и толщине металлические арматуры 2 прямоугольного сечения так, чтобы они лежали широкой стороной на одном уровне. Эти лежащие арматуры 2, располагаются продольно, поперечно и/или по другим направлениям относительно от положения каркасных опор 1. Пересечением арматур образуется сеть ячеек многоугольной формы, размер которых зависит от прочности на изгибе рамок ячеек и пластин 5, закрывающих эти ячейки. Перпендикулярно этим лежащим арматурам 2 соединить сваркой вдоль и посредине их обратной широкой стороны стоящие металлические арматуры 3 того же сечения, т.е. присоединять их узкой стороной перпендикулярно к лежащим арматурам 2. Стоящие арматуры 3 служат как основание для прикрепления полоса 7 эластичного полимерного материала, толщина которого достаточна для устойчивого закрепления внешней пластины 6. Полосы 7 имеют одинаковую ширину, размер которой больше ширины стоящих арматур 3. Полосы 7 соседних по боку ячеек соединяются между собой в их завышенной части над стоящим арматурам 3 так, чтобы образовалась сеть ровных ячеек, служащая основанием для закрепления пластин 6. Шириной полосы 7 и площадью ячейки определяется объем полости, которая обусловливает гибкость корпуса. Внутренние пластины 5 изготовлены из прочных материалов в виде досок и вырезаны по форме и размеру, соответственным с формой и размером их закрываемых ячеек. Внутренние пластины 5 плотно прижимаются набором болтов, гаек и шайб, либо иным закрепленным способом к рамкам ячеек, созданным лежащими арматурами 2, обеспечивая водонепроницаемость внутреннего слоя оболочки корпуса. Внешние пластины 6 могут изготовлены из эластичных полимерных и/или прочных материалов в виде многослойных досок. Их размеры зависят от способа прикрепления к полосам 7, в частном случае последившая пластина кладётся своим краем на край предыдущей пластины, причем толщина этих краев утончена на половину в их встречной стороне. Внешние пластины 6 плотно закреплены к полосам 7 шурупами, клеем или иным способом, обеспечивая водонепроницаемость внешнего слоя оболочки корпуса. С целью поддержания устойчивости внешнего слоя перед укладкой пластин 6 в полость подушек установлены пористые материалы 4 или надувные камеры из легких эластичного полимерного материала. On the frame supports 1, fix by welding or in another way the metal reinforcement 2 of rectangular cross section, identical in width and thickness, so that they lie with the wide side at the same level. These lying rebars 2 are arranged longitudinally, transversely and / or in other directions relative to the position of the frame supports 1. By crossing the rebars, a network of polygonal cells is formed, the size of which depends on the flexural strength of the cell frames and plates 5 covering these cells. Perpendicular to these lying reinforcing bars 2, by welding, along and in the middle of their opposite wide sides, are standing metal reinforcing bars 3 of the same section, i.e. connect them with the narrow side perpendicular to the lying reinforcing bars 2. Standing reinforcing bars 3 serve as the basis for attaching a strip 7 of elastic polymer material, the thickness of which is sufficient for stable fastening of the outer plate 6. The strips 7 have the same width, the size of which is larger than the width of the standing reinforcement 3. Strips 7 adjacent on the side of the cells are interconnected in their inflated part above the standing reinforcement 3 so that a network of even cells is formed, which serves as the basis for fixing the plates 6. Width of the strip 7 and the area The cell volume is determined by the volume of the cavity, which determines the flexibility of the body. The inner plates 5 are made of durable materials in the form of boards and are cut out in shape and size, corresponding to the shape and size of their closed cells. The inner plates 5 are tightly pressed by a set of bolts, nuts and washers, or in another fixed way to the cell frames created by the lying fittings 2, ensuring the waterproofness of the inner layer of the shell casing. The outer plates 6 may be made of elastic polymer and / or durable materials in the form of multilayer boards. Their sizes depend on the method of attachment to the strips 7, in the particular case the subsequent plate is placed with its edge on the edge of the previous plate, and the thickness of these edges is half thinned in their opposite side. The outer plates 6 are tightly fixed to the strips 7 with screws, glue, or otherwise, ensuring the waterproofness of the outer layer of the shell casing. In order to maintain the stability of the outer layer before laying the plates 6 in the cavity of the pillows, porous materials 4 or inflatable chambers made of lightweight flexible polymer material are installed.
