Description

КРЕПЕЖНЫЙ ЭЛЕМЕНТ FIXING ELEMENT
Настоящая полезная модель относится к крепежным элементам в области строительства, в частности для крепления теплоизоляционных, облицовочных материалов на поверхности из легкого и суперлегкого бетона, а также для крепления плит опалубки, рекламных изделий, вывесок, различных деталей и изделий. This utility model relates to fasteners in the field of construction, in particular for fastening heat-insulating, facing materials on surfaces made of light and ultra-light concrete, as well as for fastening formwork panels, advertising products, signboards, various parts and products.
В уровне техники широко известны крепежные элементы для фиксации теплоизолирующих плит на несущей конструкции, которые содержат пластиковый дюбель - стержень на одном конце которого расположена прижимная пластина, а на другом растирающиеся части для удержания стержня в стене и металлический штифт (ЕР0074469, 23.03.1983, E04D3/36). In the prior art, fasteners for fixing heat-insulating plates on a supporting structure are widely known, which contain a plastic dowel - a rod at one end of which is a pressure plate and rubbed parts on the other to hold the rod in the wall and a metal pin (EP0074469, 03.23.1983, E04D3 / 36).
Известный крепежный элемент не позволяет надежно закрепить на стенах, изготовленных из легкого и суперлегкого бетона и аналогичных материалах малой плотности поскольку при грубых сверлениях и винтовых нагелях в качестве разжимного элемента, разжимной элемент может относительно легко выпадать из отверстия вместе с распорным дюбелем. Кроме этого, наличие обязательного металлического штифта усложняет процесс монтажа крепежного элемента. The known fastener does not allow reliable fastening on walls made of lightweight and ultra-lightweight concrete and similar low-density materials, since during rough drilling and screw pins as an expandable element, the expandable element can relatively easily fall out of the hole together with the expansion bolt shield. In addition, the presence of a mandatory metal pin complicates the mounting process of the fastener.
Известен дюбель, который содержит винтовую часть, включающую в себя конический наконечник и сердечник, и головную часть, соединенную одним концом с сердечником и имеющую фланец (выступ-буртик) на втором конце, диаметр которого больше, чем диаметр винтовой части (резьбы). Дюбель выполнен с продольной полостью, имеющей со стороны фланца заходный участок шестигранного поперечного сечения. Распространенная после заходного участка часть полости имеет цилиндрическую форму с круглым поперечным сечением (RU 2340800, 15.05.2007, Е16В 13/00). Known dowel, which contains a screw part including a conical tip and a core, and a head part connected at one end to the core and having a flange (protrusion-shoulder) at the second end, the diameter of which is larger than the diameter of the screw part (thread). The dowel is made with a longitudinal cavity having an inlet portion of a hexagonal cross section on the flange side. The part of the cavity that is widespread after the entry section has a cylindrical shape with a round cross section (RU 2340800, 05/15/2007, ЕВВ 13/00).
Недостатком известного дюбеля является ограниченная функциональность его применения вследствие неизменяемого диаметра прижимной пластины, что не позволяет закрепить материалы в труднодоступных местах, например, из-за большого размера прижимной пластины становится невозможным закрепление материалов в угловых зонах, либо из-за низкой плотности теплоизолирующих материалов диаметра прижимной пластины может быть недостаточно для его надежного закрепления. Известен аналог, а также прототип для данной полезной модели - крепежный элемент для монтажа теплоизолирующих материалов и устройств на несущей конструкции из легкого бетона (RU 131396, 20.08.2013, Е04В1/76), содержащий стержневой держатель с прижимной перфорированной пластиной и переходным утолщением, концевая часть стержня держателя имеет наружную резьбу, которая выполнена с увеличивающимся диаметром витков в направлении к прижимной пластине, а в прижимной пластине и переходном утолщении выполнено осевое отверстие, ограниченное упорной площадкой и имеющее в своем сечении форму шестигранника или квадрата или тора. A disadvantage of the known dowel is the limited functionality of its use due to the unchanged diameter of the pressure plate, which does not allow fixing materials in hard-to-reach places, for example, due to the large size of the pressure plate, it becomes impossible to fix materials in corner zones, or because of the low density of heat-insulating materials of the diameter of the pressure plate the plate may not be enough to secure it securely. A known analogue, as well as a prototype for this utility model, is a fastener for mounting heat-insulating materials and devices on a supporting structure made of light concrete (RU 131396, 08.20.2013, Е04В1 / 76), containing a rod holder with a clamping perforated plate and transitional thickening, end part of the holder rod has an external thread, which is made with an increasing diameter of the turns in the direction of the pressure plate, and in the pressure plate and the transitional thickening there is an axial hole bounded by a thrust pad and having the shape of a hexagon or square or torus in its cross section.
Известный крепежный элемент для монтажа теплоизолирующих материалов и устройств на несущей конструкции из легкого бетона используют следующим способом. Для крепления утеплителя на фасад здания предварительно насверливают отверстие подходящего диаметра в стеновой панели из легкого бетона и, подготовив инструмент, закрепив в патрон, (например, электродрели или электрической отвертки) биту, шестигранник, квадрат или тор, в зависимости от выбранного элемента крепления и конфигурации осевого отверстия, вставляют биту в осевое отверстие стержневого держателя и закручивают в предварительно просверленное отверстие крепежный элемент до соприкосновения поверхности прижимной пластины и поверхности утеплителя. При закручивании крепежный элемент наружной резьбой нарезает резьбу в предварительно засверленном отверстии, что дает более прочное соединение в отличие от анкеровки, так как последняя крепится посредством вводимого в осевое отверстие штифта, что, как показывает анализ крепления по истечении некоторого времени, вызывает напряжение в стеновой панели из легкого бетона и ломает перегородки- пустоты, например, при креплении в пенобетоне. The known fastener for mounting insulating materials and devices on a supporting structure of lightweight concrete is used in the following way. To fasten the insulation on the building facade, a hole of suitable diameter is pre-drilled in the wall panel of light concrete and, having prepared the tool, secured in the cartridge (for example, an electric drill or an electric screwdriver) a bat, hexagon, square or torus, depending on the selected mounting element and configuration axial holes, insert the bit into the axial hole of the rod holder and screw the fastening element into the pre-drilled hole until the surface of the pressure plate and the surface of the insulation come into contact. When tightening the fastener, the external thread cuts the thread in the pre-drilled hole, which gives a stronger connection as opposed to anchoring, since the latter is fastened by means of a pin inserted into the axial hole, which, as the analysis of the fastening shows after some time, causes tension in the wall panel made of lightweight concrete and breaks partitions, voids, for example, when mounted in foam concrete.
К недостаткам данного аналога можно отнести необходимость предварительного высверливания отверстия и неизменяемый диаметр прижимной пластины, что не позволяет без её срезания, закрепить материалы в труднодоступных местах, например, из-за большого размера прижимной пластины становится невозможным закрепление материалов в угловых зонах, либо из-за низкой плотности теплоизолирующих материалов диаметра прижимной пластины может быть недостаточно для его надежного закрепления. The disadvantages of this analogue include the need for preliminary drilling of the hole and the unchanged diameter of the pressure plate, which does not allow cutting it to fix materials in hard-to-reach places, for example, due to the large size of the pressure plate, it becomes impossible to fix the materials in the corner zones, or because the low density of heat-insulating materials, the diameter of the pressure plate may not be enough to secure it.
Техническим результатом предлагаемой полезной модели является надёжное закрепление теплоизолирующих материалов в труднодоступных местах. Например, в угловых местах соединения, где нельзя использовать известные крепежные элементы ввиду большого диаметра шляпок. Технический результат достигается тем, что крепежный элемент для монтажа теплоизолирующих материалов и устройств на несущей конструкции из легкого бетона, содержащий стержень, на одном конце которого имеется наружная резьба, а на другом выступ-буртик, которая взаимодействует прижимной пластиной, которая выполнена съёмной. Прижимная пластина и шляпка стержня могут иметь элементы фиксации. The technical result of the proposed utility model is the reliable fixing of heat-insulating materials in hard-to-reach places. For example, in corner junctions where known fasteners cannot be used due to the large diameter of the caps. The technical result is achieved by the fact that the fastener for mounting heat-insulating materials and devices on a supporting structure made of light concrete, containing a rod, on one end of which there is an external thread, and on the other ledge is a shoulder that interacts with a pressure plate that is removable. The pressure plate and the cap of the rod may have locking elements.
Наличие съёмной прижимной пластины позволяет использовать широкий спектр размеров и форм прижимных пластин для крепления теплоизоляции в зависимости от её плотности, либо при необходимости закрепления в труднодоступных местах, а наконечник с режущей кромкой исключает необходимость предварительного высверливания отверстий. Фиксирующие элементы надежно закрепляют прижимную пластину на переходном утолщении стержня. The presence of a removable pressure plate allows you to use a wide range of sizes and shapes of pressure plates to fix the insulation, depending on its density, or if necessary to fix it in hard to reach places, and the tip with a cutting edge eliminates the need for pre-drilling holes. The locking elements securely fasten the pressure plate to the transitional thickening of the rod.
Это устройство представляет собой крепежный элемент по форме напоминающий саморез или шуруп с прижимной пластиной, который пропускается через толщину теплоизолирующей панели и концевой частью вворачивается в стену и может использоваться для монтажа опалубки из любого влагостойкого и достаточно прочного листового материала (в частности, полистирола вспененного, экструзионного полистирола), соединения слоев теплоизоляции между собой, крепления углов, откосов и пароизоляции на вент фасаде, соединения слоев теплоизоляции к легким бетонам, а также кровельных работ, закручивая крепежный элемент с помощью выполненного в нём отверстия, без предварительного засверливания прижимаемой поверхности. Прижимная пластина подбирается под необходимый размер и предположительно фиксируется на шляпке стержня крепежного элемента. В функцию этой пластины входит возможность прижима к теплоизолирующей плите после ввода стержня по всей его длине в стеновую конструкцию. This device is a fastener in shape resembling a self-tapping screw or screw with a pressure plate, which is passed through the thickness of the heat-insulating panel and screwed into the wall with the end part and can be used to mount formwork from any moisture-proof and sufficiently strong sheet material (in particular, expanded polystyrene, extrusion polystyrene), joining layers of thermal insulation to each other, fixing corners, slopes and vapor barrier on the vent facade, joining layers of thermal insulation to light concrete, as well as roofing, twisting the fastener with the hole made in it, without first drilling the pressed surface. The pressure plate is selected to the required size and is presumably fixed to the cap head of the fastener. The function of this plate includes the ability to clamp to a heat-insulating plate after entering the rod along its entire length into the wall structure.

Крепежный элемент для монтажа теплоизолирующих материалов содержит стержень 1, на одном конце которого имеется выступ-буртик 4, а на части противоположного конца стержень содержит наружную резьбу 5. В выступе 4 и стержне 1 выполнено осевое отверстие 6. Осевое отверстие 6 в сечении имеет форму многоугольника, например, шестиугольника. Отверстие необходимо для взаимодействия с рабочим органом завинчивающего устройства, например шуруповерта. При этом рабочий орган (насадка) шуруповерта имеет шестигранную форму, может иметь трех или четырехгранную форму. The fastener for mounting heat-insulating materials contains a rod 1, at one end of which there is a protrusion-shoulder 4, and on the part of the opposite end the rod contains an external thread 5. In the protrusion 4 and the rod 1 there is an axial hole 6. The axial hole 6 in cross section has the shape of a polygon , for example, a hexagon. The hole is necessary for interaction with the working body of the screw device, such as a screwdriver. In this case, the working body (nozzle) of the screwdriver has a hexagonal shape, may have a triangular or quadrangular shape.
Отверстие 6 может быть выполнено вдоль всего крепежного элемента, а может только в части. При этом отверстие может быть все выполнено в сечении в виде многоугольника, а может иметь начальный участок у края выступа-буртика 4, имеющее шестиугольное поперечное сечение, а остальная часть отверстия 6 - цилиндрическая с круглым поперечным сечением. The hole 6 can be made along the entire fastener, and can only in part. In this case, the hole can be made in the cross section in the form of a polygon, and may have an initial section at the edge of the protrusion flange 4, having a hexagonal cross section, and the rest of the hole 6 is cylindrical with a circular cross section.
Выступ 4 выполняется конической либо цилиндрической формы, который предотвращает попадание пыли и мусора с краев отверстия в полость крепежного элемента, а также служит для предотвращения неконтролируемого заглубления. При этом в поперечном сечении форма выступа может быть круглой, а может иметь форму многоугольника. The protrusion 4 is made conical or cylindrical in shape, which prevents dust and debris from the edges of the hole from entering the cavity of the fastener, and also serves to prevent uncontrolled penetration. Moreover, in the cross section the shape of the protrusion may be round, and may have the shape of a polygon.
Прижимная пластина 2 содержит входное отверстие 7 соответствующее диаметру выступающей резьбы 5, но менее диаметра выступа 4. В предпочтительном варианте выполнения пластины 2 соосно отверстию в ней выполнена выемка 8, соответствующая размеру выступа-буртика 4. The pressure plate 2 contains an inlet 7 corresponding to the diameter of the protruding thread 5, but less than the diameter of the protrusion 4. In a preferred embodiment of the plate 2, a recess 8 is made coaxially with the hole in it, corresponding to the size of the shoulder 4.
Для надежного закрепления прижимной пластины 2 на стержне 1 выполнены фиксирующие элементы в виде выступов 9, а на пластине 2 элементы фиксации 10. Элемент фиксации 10 на прижимной пластине 2 выполнен в виде обращенного внутрь удерживающего упругого выступа 13 на выемке 8 входного отверстия 7. Удерживающий выступ 13 для облегчения вхождения в фиксирующий элемент 10 стержня 1 имеет по меньшей мере один вырез 16 и наклонную поверхность 17. Элемент фиксации 9 выполнен в виде выступа 14 имеющего опорную площадку 15. При установке прижимной пластины 2 на стержень 1, в момент прохождения выемки 8 прижимной пластины 2, удерживающий выступ 13 как бы раздвигается за счёт выреза 16 и давления оказываемого выступом 14 на наклонную поверхность 17. При полном прохождении выступа 14, удерживающий выступ 13, за счёт силы упругости возвращается в исходное положение и жестко фиксируется на опорной площадке 15. Таким образом прижимная пластина 2 надежно закрепляется на стержне 1, с одной стороны за счёт давления буртика 4 на выемку 8, с другой стороны за счёт жесткой фиксации элементов 9 и 10. For reliable fastening of the pressure plate 2 on the rod 1, fixing elements are made in the form of protrusions 9, and on the plate 2 fixing elements 10. The fixing element 10 on the pressure plate 2 is made in the form of an inwardly retaining elastic protrusion 13 in the recess 8 of the inlet 7. Holding protrusion 13 to facilitate entry into the fixing element 10 of the rod 1 has at least one cutout 16 and an inclined surface 17. The fixing element 9 is made in the form of a protrusion 14 having a support pad 15. When installing the pressure plate 2 on the rod 1, at the time of passage of the recess 8 of the pressure plate 2, the retaining protrusion 13 as it extends due to the cutout 16 and the pressure exerted by the protrusion 14 on the inclined surface 17. With the passage of the protrusion 14, the retaining protrusion 13, due to the elastic force, returns to its original position and is rigidly fixed on the supporting platform 15. Thus thus, the pressure plate 2 is securely fixed to the rod 1, on the one hand due to the pressure of the shoulder 4 on the recess 8, on the other hand due to the rigid fixation of the elements 9 and 10.
Так же есть возможность закрепления прижимной пластины 2 на стержне 1 без использования фиксирующих элементов 9 и 10. Для этого на прижимной пластине 2 имеется выемка 8, и буртик 4 стержня 1. Буртик 4 может фиксироваться в выступе 8 за счёт выполнения их в форме многоугольника не давая прокручиваться прижимной пластине 2 на стержне 1 и удерживая её при вкручивании. It is also possible to fix the pressure plate 2 on the rod 1 without using the fixing elements 9 and 10. For this, the pressure plate 2 has a recess 8, and a collar 4 of the rod 1. The collar 4 can be fixed in the protrusion 8 due to their execution in the form of a polygon preventing the pressure plate 2 from scrolling on the rod 1 and holding it while screwing it in.
Для использования крепежного элемента на более плотных поверхностях на его конце с резьбой установлен металлический наконечник с режущей кромкой 3 (например, как описано в патента US4601625), который содержит по меньшей мере один заостренный кончик 11 и по меньшей мере одну режущую кромку 12, который работает как саморез. To use the fastener on denser surfaces, a metal tip with a cutting edge 3 is installed at its threaded end (for example, as described in US4601625), which contains at least one pointed tip 11 and at least one cutting edge 12 that operates like a screw.
Наконечник с режущей кромкой 3 также служит для возможности использования крепежного элемента без предварительного высверливания отверстия. Для этого он содержит заостренный кончик 11 и по меньшей мере одну режущую кромку 12. Предпочтительно наконечник с режущей кромкой 3 выполнен из металла и позволяет высверливать отверстие непосредственно в процессе его использования. A tip with a cutting edge 3 also serves to enable the use of a fastener without first drilling a hole. To this end, it contains a pointed tip 11 and at least one cutting edge 12. Preferably, the tip with a cutting edge 3 is made of metal and allows you to drill a hole directly during its use.
Крепежный элемент для монтажа теплоизолирующих материалов и устройств на несущей конструкции из легкого бетона используется следующим образом: A fastener for mounting heat-insulating materials and devices on a supporting structure of lightweight concrete is used as follows:
В частности, такой крепеж используется для крепления утеплителя на фасад здания. Предварительно подбирается подходящего размера прижимная пластина 2, с учётом доступа в месте прикручивания, либо с учётом плотности изолирующего материала. Прижимная пластина 2 устанавливается на стержень 1, до соприкосновения шляпки 4 и выемки 8, размер и форма выемки 8 и шляпки 4 выполнены в соответствии друг другу, и предпочтительно закрепляется при помощи фиксатора 9 выполненного на стержне 1 и фиксатора 10 выполненного на пластине 2. In particular, such fasteners are used to fasten the insulation to the building facade. Pre-selected a suitable size of the pressure plate 2, taking into account access at the place of screwing, or taking into account the density of the insulating material. The pressure plate 2 is mounted on the rod 1, until the cap 4 and the recess 8 are in contact, the size and shape of the recess 8 and the cap 4 are made in accordance with each other, and is preferably fixed using the latch 9 made on the rod 1 and the latch 10 made on the plate 2.
При необходимости, например, из-за высокой твердости стеновой панели, высверливается отверстие подходящего диаметра, либо высверливание отверстия происходит непосредственно крепежным элементом при помощи наконечника с режущей кромкой. Подготовив инструмент, закрепив в патрон, (например, шуруповерта или электрической отвертки) насадку шестигранник, квадрат или тор, в зависимости от выбранного элемента крепления и конфигурации осевого отверстия, вставляют насадку в осевое отверстие 6 и закручивают крепежный элемент до соприкосновения поверхности прижимной пластины 2 и поверхности утеплителя. При закручивании крепежный элемент наружной резьбой 5 нарезает резьбу, что дает более прочное соединение в отличие от анкеровки, так как последняя крепится посредством вводимого в осевое отверстие штифта, что, как показывает анализ крепления по истечении некоторого времени, вызывает напряжение в стеновой панели из легкого бетона и ломает перегородки-пустоты, например, при креплении в пенобетоне. При креплении между собой листов утеплителя нет необходимости засверливать предварительно отверстия, крепежный элемент закручивается, используя наружную резьбу 5 до необходимого усилия. If necessary, for example, due to the high hardness of the wall panel, a hole of a suitable diameter is drilled, or the hole is drilled directly by a fastener using a tip with a cutting edge. Having prepared the tool, securing the nozzle with a hexagon, square or torus in the chuck (for example, a screwdriver or an electric screwdriver), depending on the selected fastening element and configuration of the axial hole, insert the nozzle into the axial hole 6 and tighten the fastening element until the surface of the pressure plate 2 contacts insulation surface. When tightening the fastening element, an external thread 5 cuts the thread, which gives a stronger connection, unlike anchoring, since the latter is fastened by means of a pin inserted into the axial hole, which, as the fastening analysis shows after some time, causes tension in the lightweight concrete wall panel and breaks the void partitions, for example, when mounted in foam concrete. When attaching insulation sheets to each other, there is no need to drill pre-holes, the fastener is twisted using an external thread 5 to the required force.
Использование съемных пластин 2 дает возможность подобрать необходимый размер и диаметр пластин, что позволяет наиболее эффективно и надежно использовать крепежный элемент в труднодоступных местах, ограниченных пространствах, например, в углах. The use of removable plates 2 makes it possible to select the required size and diameter of the plates, which allows the fastest and most reliable use of the fastener in hard-to-reach places, confined spaces, for example, in corners.
