Description

Изобретение относится к полносборным теплоизоляционным конструкциям для изоляции трубопроводов, резервуаров, промышленного оборудования и строительных конструкций и может найти применение в строительстве. 5The invention relates to prefabricated insulating structures for insulation of pipelines, tanks, industrial equipment and building structures and can find application in construction. 5

Известны полносборные теплоизоляционные конструкции, выполненные в виде состыкованных между собой упругих элементовполос из упругого материала, например минеральной ваты, закрепленных на покровном слое [1].Known prefabricated heat-insulating structures made in the form of stacked together elastic elements of strips of elastic material, such as mineral wool, mounted on the cover layer [1].

Однако в период эксплуатации такой теплоизоляционной конструкции происходит усадка минераловатного слоя, при этом проявляется зазор между изолируемым объектом и теплоизоляционной конструкцией, вследствие чего существенно снижается эффективность теплоизоляции.However, during the operation of such a heat-insulating structure, the mineral wool layer shrinks, and a gap appears between the insulated object and the heat-insulating structure, as a result of which the efficiency of thermal insulation is significantly reduced.

Наиболее близкой к предлагаемой по технической сущности и достигаемому результату является полносборная теплоизоляцион- 20 ная конструкция, содержащая состыкованные между собой жесткие теплоизоляционные элементы, например из пенопласта, закрепленные на покровном слое. Для обес2 печения плотного прилегания элементов друг к другу в рабочем положении их сопрягаемые грани выполняются со скосами. При этом угол скоса выбирается в зависимости от радиуса кривизны изолируемой поверхности [2].The closest to the proposed technical essence and the achieved result is a fully-assembled heat-insulating 20-ny structure containing rigid heat-insulating elements joined together, for example, of foam, fixed to the coating layer. To ensure tight fit of the elements to each other in the working position, their mating faces are made with bevels. In this case, the bevel angle is selected depending on the radius of curvature of the insulated surface [2].

Необходимость выполнения скосов на боковых гранях теплоизоляционных элементов ограничивает применение известной конструкции строго определенным радиусом кривизны изолируемой поверхности, что вызывает необходимость изготовления большого парка форм для изделий различных типоразмеров и,’ в конечном итоге, сдерживает рост производительности труда при изготовлении и монтаже конструкций.The need to make bevels on the lateral faces of heat-insulating elements limits the use of the known design to a strictly defined radius of curvature of the insulated surface, which necessitates the manufacture of a large fleet of molds for products of various sizes and, ultimately, inhibits the growth of labor productivity in the manufacture and installation of structures.

Цель изобретения — обеспечение универсальности, повышение производительности труда при изготовлении и монтаже тепловой изоляции.The purpose of the invention is the provision of versatility, increasing labor productivity in the manufacture and installation of thermal insulation.

Цель достигается тем, что в гибком теплоизоляционном материале, выполненном .из состыкованных между собой и закрепленных на покровном слое жестких теплоизоляционных элементов, стыки последних выполнены в виде шарнирных соединений, образованных пазами и выступами цилиндрической формы, расположенными на сопрягаемых гранях элементов, а покровный слой выполнен с компенсаторами, ориентированными параллельно стыкам теплоизоляционных элементов.The goal is achieved in that in a flexible heat-insulating material made of rigid heat-insulating elements joined to each other and fixed on the cover layer, the joints of the latter are made in the form of hinged joints formed by grooves and protrusions of a cylindrical shape located on the mating faces of the elements, and the cover layer is made with compensators oriented parallel to the joints of the insulating elements.

На фиг. 1 изображен предлагаемый гибкий теплоизоляционный материал; на фиг. 2 — фрагмент изоляции трубы с помощью предлагаемой конструкции; на фиг. .3 — вариант выполнения конструкции.In FIG. 1 shows the proposed flexible thermal insulation material; in FIG. 2 - fragment of pipe insulation using the proposed design; in FIG. .3 is an embodiment of the structure.

Гибкий теплоизоляционный материал содержит жесткие теплоизоляционные элементы 1, выполненные из вспененных пластмасс (на основе фенолформальдегидных и полиуретановых смол, полистирола, полиэтилена и др.) или силикатных теплоизоляционных масс (известково-кремнеземистых, на основе перлита и т. п.), и покровный слой 2. На сопрягаемых гранях теплоизоляционных элементов выполнены пазы 3 и выступы 4 цилиндрической формы, образующие шарнирные соединения в местах стыков. При этом длина дуги выступа больше длины дуги полуокружности и дуги паза. Покровный слой 2 снабжен компенсаторами 5, ориентированными параллельно стыкам элементов 1. Компенсаторы 5 выполнены в виде гофр или складок покровного материала, образуемых в процессе изготовления конструкции. Гофры могут быть выполнены по всему покровному слою — мелкая гофра (фиг. 1) или только в местах расположения стыков теплоизоляционных элементов (фиг. 2 и 3). Крепление теплоизоляционных элементов 1 к покровному слою 2 осуществляется с помощью клеевых соединений или стандартного крепежа (на чертеже не показаны).A flexible heat-insulating material contains rigid heat-insulating elements 1 made of foamed plastics (based on phenol-formaldehyde and polyurethane resins, polystyrene, polyethylene, etc.) or silicate heat-insulating materials (lime-siliceous, based on perlite, etc.), and a coating layer 2. On the mating faces of the heat-insulating elements, grooves 3 and protrusions 4 of a cylindrical shape are made, forming articulated joints at the joints. The length of the arch of the protrusion is greater than the length of the arc of the semicircle and the arc of the groove. The cover layer 2 is equipped with compensators 5 oriented parallel to the junctions of the elements 1. The compensators 5 are made in the form of corrugations or folds of the coating material formed in the manufacturing process of the structure. Corrugations can be made throughout the entire coating layer - a small corrugation (Fig. 1) or only at the locations of the joints of the insulating elements (Figs. 2 and 3). The fastening of the insulating elements 1 to the cover layer 2 is carried out using adhesive joints or standard fasteners (not shown in the drawing).

При изготовлении конструкции выступы 4 вставляют в пазы 3 соседнего элемента 1, после чего соединяют теплоизоляционные элементы с покровным слоем 2. Готовые изделия, благодаря провороту элементов 1 относительно друг друга в шарнирных соединениях, образованных пазами 3 и выступами 4, и растягиванию компенсаторов 5, сворачивают в рулоны и отправляют на монтаж, где в зависимости от размеров изоли5 руемых объектов производят их раскрой на полотна необходимой длины. При монтаже конструкций им придают форму любой криволинейной или плоской поверхности за счет поворота элементов 1 относительно друг друга и растягивания компенсаторов 5. ¹⁰ Использование изобретения позволяет наладить поточное производство универсальных полносборных теплоизоляционных конструкций. Ожидаемый экономический эффект от внедрения изобретения составляет ₁₅ 1166 тыс. руб.In the manufacture of the structure, the protrusions 4 are inserted into the grooves 3 of the adjacent element 1, after which the heat-insulating elements are connected to the cover layer 2. The finished products, due to the rotation of the elements 1 relative to each other in the swivel joints formed by the grooves 3 and the protrusions 4, and stretching the compensators 5, are rolled in rolls and sent for installation, where, depending on the size of the insulated objects, they are cut into canvases of the required length. When assembling structures, they are shaped into any curved or flat surface due to the rotation of the elements 1 relative to each other and stretching of the compensators 5. ¹⁰ Using the invention allows to set up in-line production of universal prefabricated heat-insulating structures. The expected economic effect from the implementation of the invention is ₁₅ 1166 thousand rubles.

Claims

The invention relates to complete thermal insulating structures for the insulation of pipelines, tanks, industrial equipment and building structures and may find application in construction. Full-assembled thermal insulation structures are known, made in the form of elastic elements joined to each other from elastic material, such as mineral wool, fixed on the covering layer 1. However, during the operation of such thermal insulation, the mineral wool layer shrinks, and a gap appears between the insulated object and a heat insulating structure, as a result of which the heat insulating efficiency is significantly reduced. Closest to the proposed technical essence and the achieved result is a full-assembled heat-insulating structure containing rigid heat-insulating elements joined together with one another, for example, foam plastic, mounted on a covering layer. To ensure that the elements fit snugly together in the working position, their mating faces are made with bevels. The bevel angle is selected depending on the radius of curvature of the insulated surface 2. The need to make bevels on the lateral faces of the heat insulating elements limits the use of the known construction to a strictly defined radius of curvature of the insulated surface, which necessitates the manufacture of a large fleet of forms for products of various sizes and, ultimately as a result, hinders the growth of labor productivity in the manufacture and installation of structures. The purpose of the invention is to ensure versatility, increase productivity in the manufacture and installation of thermal insulation. The goal is achieved by the fact that in a flexible heat insulating material made of rigid rigid insulation elements that are joined to each other and fixed on a covering layer, the joints of the latter are made in the form of hinged joints formed by grooves and cylindrical protrusions located on the matched edges of the elements , and the covering layer is made with compensators oriented parallel to the joints of the heat insulating elements. FIG. 1 shows the proposed flexible thermal insulation material; in fig. 2 - a fragment of pipe insulation using the proposed construction; in fig. .3 embodiment of the design. Flexible heat insulating material contains rigid heat insulating elements 1 made of foamed plastics (based on phenol formaldehyde and polyurethane resins, polystyrene, polyethylene, etc.) or silicate heat insulating masses (lime-silica, perlite-based, etc.), and a covering layer 2. Grooves 3 and cylindrical protrusions 4 are formed on the matching edges of the heat insulating elements, which form hinged joints at the joints. The length of the arc of the protrusion is greater than the length of the arc of the semicircle and the arc of the groove. The covering layer 2 is provided with compensators 5 oriented parallel to the joints of the elements 1. The compensators 5 are made in the form of corrugations or folds of the covering material formed during the manufacture of the structure. The corrugations can be made along the entire coating layer — small corrugation (Fig. 1) or only at the locations of the joints of the heat insulating elements (Fig. 2 and 3). The fastening of the heat insulating elements 1 to the covering layer 2 is carried out using adhesive joints or standard fasteners (not shown in the drawing). In making the construction, the protrusions 4 are inserted into the grooves 3 of the neighboring element 1, after which the heat insulating elements are connected to the cover layer 2. The finished products, due to the rotation of the elements 1 relative to each other in the hinged joints formed by the grooves 3 and the projections 4, and The expansion of the compensators 5 is rolled up into rolls and sent to the assembly, where, depending on the size of the insulated objects, they are cut into sheets of the required length. When assembling the structures, they are shaped into any curved or flat surface due to the rotation of the elements 1 relative to each other and the expansion of the compensators 5. The use of the invention allows for the on-line production of universal prefabricated thermal insulation structures. The expected economic effect from the implementation of the invention is 1,166 thousand rubles.
