Description
Узел соединения деревянных балок Knot of connection of wooden beams
Полезная модель относится к средствам соединения строительных конструкций и может быть использована в несущих конструкциях при строительстве структур трехмерных соединений для кровельных перекрытий различных типов зданий, таких как спортивные залы, конференц-залы, выставочные залы, бассейны, шатры и т.д. The utility model relates to means of connecting building structures and can be used in load-bearing structures in the construction of three-dimensional connection structures for roofing of various types of buildings, such as sports halls, conference halls, exhibition halls, swimming pools, tents, etc.
Из источника RU 149596 Ul, Е04С 3/12, 10.01.2015 известно узловое соединение двух и более балок, каждая из которых одним из своих концов примыкает к соединительному элементу, с помощью встроенного анкера, выполненного из пластиковой трубы (полихлорвиниловая PVC, или полипропиленовая, или полиэтиленовая, или из композитных материалов), установленная в углубление, расположенное внутри балки на всю ее длину или на ее часть. From the source RU 149596 Ul, Е04С 3/12, 01/10/2015, nodal connection of two or more beams is known, each of which adjoins the connecting element with one of its ends, using an integrated anchor made of a plastic pipe (polyvinyl chloride PVC, or polypropylene, or polyethylene, or from composite materials), installed in a recess located inside the beam for its entire length or for part of it.
Недостатком такого узла является низкая прочность соединения, поскольку пластиковая втулка, вклеенная в отверстие детали, при температурном нагреве (на солнце, например) будет иметь тенденцию к механическому разрушению клеевого соединения и далее нарушении целостности конструкции, следовательно, при длительных статических и динамических нагрузках и при температурном нагреве внутренняя пластиковая резьба имеет тенденцию к разрушению, что приведет к разрушению болтового соединения и как результат всей конструкции. The disadvantage of such an assembly is the low strength of the connection, since the plastic sleeve, glued into the hole of the part, during temperature heating (in the sun, for example) will tend to mechanical destruction of the adhesive joint and further violate the integrity of the structure, therefore, under prolonged static and dynamic loads and when Under thermal heating, the internal plastic thread tends to break, which will lead to the destruction of the bolted connection and, as a result, the entire structure.
Технический результат, достигаемый заявленной полезной моделью, заключается в повышении прочности и несущей способности узлового соединения деревянных балок. The technical result achieved by the claimed utility model is to increase the strength and bearing capacity of the nodal connection of wooden beams.
Заявленный технический результат достигается за счет использования узла соединения балок, содержащего металлический коннектор и соединенные с ним посредством элементов крепления балки, выполненные из клееной древесины, при этом элементы крепления выполнены в виде металлических втулок с внутренней резьбой, которые вставляются и вклеиваются в продольные глухие отверстия, просверленные на торцевых концах балок и частично заполненные клеящим составом, заполняющим зазор, образующийся между отверстием балки и цилиндрической поверхностью втулки, когда она вставлена в данное отверстие, при этом коннектор соединен с балками посредством металлических болтов, вкрученных в резьбовое отверстие втулок, жестко связывающих коннектор с балками. The claimed technical result is achieved through the use of a beam connection unit containing a metal connector and beams connected to it by means of fastening elements made of glued wood, while the fastening elements are made in the form of metal bushings with internal threads that are inserted and glued into longitudinal blind holes, drilled at the end ends of the beams and partially filled with an adhesive that fills the gap formed between the beam hole and the cylindrical surface of the sleeve when it is inserted into this hole, while the connector is connected to the beams by means of metal bolts screwed into the threaded hole of the bushings, rigidly connecting the connector with beams.
Выполнение элементов крепления в виде металлических втулок и болтов обеспечивает большую прочность и несущую способность конструкции исходя из
особенностей материала, поскольку металлическая втулка увеличивает возможные нагрузки на конструкцию в 5 и более раз. The implementation of the fastening elements in the form of metal bushings and bolts provides greater strength and load-bearing capacity of the structure based on features of the material, since the metal sleeve increases the possible load on the structure by 5 or more times.
Клеящий состав заполняет зазор, образующийся между просверленным отверстием балки и цилиндрической поверхностью втулки, когда она вставлена в данное отверстие. После затвердевания клей обеспечивает прочное и не разъемное соединение втулки и балки и окружает цилиндрическую поверхность втулки по всей ее длине, передавая нагрузки и напряжения коннектору возникающие в точках крепления в конструкции параллельно древесным волокнам, таким образом, повышая прочность соединения и увеличивая несущую способность узлового соединения деревянных балок. The adhesive fills the gap formed between the drilled hole in the beam and the cylindrical surface of the sleeve when it is inserted into the hole. After hardening, the adhesive provides a strong and non-detachable connection between the sleeve and the beam and surrounds the cylindrical surface of the sleeve along its entire length, transferring loads and stresses to the connector that occur at the attachment points in the structure parallel to the wood fibers, thus increasing the strength of the connection and increasing the bearing capacity of the nodal connection of wooden beams.
На цилиндрической поверхности каждой втулки выполнена резьба или выступы, для увеличения поверхности соприкасающейся с клеем и предотвращения прокручивания втулки, вставленной в отверстие балки, что обеспечивает повышение прочность соединения при монтаже. On the cylindrical surface of each bushing, a thread or protrusions are made to increase the surface in contact with the adhesive and prevent the bushing inserted into the beam hole from scrolling, which ensures an increase in the strength of the connection during installation.
Для обеспечения выпуска возможного избыточного количества клеящего состава и воздуха после размещения втулки в продольном отверстии балки вблизи конца каждого отверстия балок просверлены поперечные отверстия малого диаметра до пересечения с продольным отверстием балки, что обеспечивает плотное размещение втулки в отверстии и прочное клеевое соединение. To ensure the release of a possible excess amount of adhesive and air after the sleeve is placed in the longitudinal hole of the beam, transverse holes of small diameter are drilled near the end of each hole of the beams until they intersect with the longitudinal hole of the beam, which ensures tight placement of the sleeve in the hole and a strong adhesive connection.
В качестве клея используется смола или клеящий состав для деревяннометаллических соединений, обладающий хорошими склеивающими характеристиками, подходящими для получения креплений больших размеров, которые выдерживают очень высокие нагрузки. The adhesive used is a resin or wood-to-metal adhesive with good adhesive properties, suitable for making large fasteners that can withstand very high loads.
Сущность полезной модели поясняется чертежами. The essence of the utility model is illustrated by drawings.
На фигуре 1 - схема, показывающая проекцию всех деталей; The figure 1 is a diagram showing the projection of all the details;
На фигуре 2 - продольный разрез узла, показывающий концевую часть деревянной балки, в которой просверлено отверстие, вставлена и вклеена втулка, и присоединен коннектор; Figure 2 is a longitudinal section of the assembly, showing the end of a wooden beam in which a hole is drilled, a bushing is inserted and glued, and a connector is attached;
На фигуре 3 - вид в перспективе нескольких балок, соединенных друг с другом в точке крепления. The figure 3 is a perspective view of several beams connected to each other at the attachment point.
Узел соединения между собой двух и более деревянных балок (1) из клееной древесины содержит коннектор (7) для соединения балок и элементы крепления (3).
Элементы крепления (3) выполнены в виде металлических втулок (3), каждая из которых представляет собой цилиндр, имеющий осевое отверстие с внутренней резьбой (5). The joint between two or more wooden beams (1) made of glued wood contains a connector (7) for connecting the beams and fastening elements (3). Fastening elements (3) are made in the form of metal bushings (3), each of which is a cylinder having an axial hole with an internal thread (5).
На торцевом конце каждой деревянной балки (1) просверлены продольные глухие отверстия (2) в которые вставляются втулки (3). При этом, в зависимости от размеров строительной конструкций и, соответственно, размеров используемых балок, на конце балки (1) может быть выполнено одно и более продольных отверстий (2). Отверстия (2) частично заполнены объемом клеящего состава (4), достаточного для заполнения зазора, образующегося между отверстием (2) балки (1) и цилиндрической поверхностью втулки (3), когда она вставлена в данное отверстие (2). При этом для обеспечения плотного размещения втулки (3) в отверстии (2) и при этом образования необходимого зазора для клеевого состава между отверстием и цилиндрической поверхностью втулки, когда она вставлена в данное отверстие, диаметр втулки (3) немногим менее диаметра продольного отверстия (2) балки. At the end end of each wooden beam (1), longitudinal blind holes (2) are drilled into which bushings (3) are inserted. In this case, depending on the dimensions of the building structures and, accordingly, the dimensions of the beams used, one or more longitudinal holes (2) can be made at the end of the beam (1). The holes (2) are partially filled with a volume of adhesive (4) sufficient to fill the gap formed between the hole (2) of the beam (1) and the cylindrical surface of the sleeve (3) when it is inserted into this hole (2). At the same time, to ensure tight placement of the bushing (3) in the hole (2) and at the same time the formation of the necessary gap for the adhesive composition between the hole and the cylindrical surface of the bushing, when it is inserted into this hole, the diameter of the bushing (3) is slightly less than the diameter of the longitudinal hole (2 ) beams.
В качестве клея (4) используется смола или любой другой клеящий состав для деревянно-металлических соединений. Resin or any other adhesive for wood-metal joints is used as glue (4).
На цилиндрической поверхности каждой втулки (3) выполнена резьба или выступы (6) для предотвращения прокручивания втулки, вставленной в отверстие балки, и увеличения поверхности втулки соприкасающейся с клеем (4), что, следовательно, обеспечивает более надежное крепление при монтаже соединения. On the cylindrical surface of each bushing (3) there is a thread or protrusions (6) to prevent the bushing inserted into the hole of the beam from turning and to increase the surface of the bushing in contact with the adhesive (4), which, therefore, provides a more reliable fastening during the installation of the connection.
Вблизи конца каждого продольного отверстия (2) балок (1) просверлены поперечные отверстия малого диаметра до пересечения с продольным отверстием (2) балки (на фигурах не показано), обеспечивающие выпуск возможного избыточного количества клеящего состава (4) и воздуха после размещения втулки в отверстии балки. Near the end of each longitudinal hole (2) of the beams (1), transverse holes of small diameter are drilled to the intersection with the longitudinal hole (2) of the beam (not shown in the figures), ensuring the release of a possible excess amount of adhesive (4) and air after the sleeve is placed in the hole beams.
После затвердевания клей (смола) (4) окружает цилиндрическую поверхность втулки (3) по всей ее длине. Таким образом, клей (смола) (4) передает нагрузки и напряжения коннектору (7), возникающие в точках крепления в конструкции параллельно древесным волокнам, тем самым увеличивая прочность соединения. After hardening, the adhesive (resin) (4) surrounds the cylindrical surface of the sleeve (3) along its entire length. Thus, the adhesive (resin) (4) transfers the loads and stresses to the connector (7) that occur at the attachment points in the structure parallel to the wood fibers, thereby increasing the strength of the connection.
Соединение между собой двух или более балок получается путем соединения балок (1) к металлическому коннектору (7). Коннектор (7) снабжен отверстиями или вертикальными пазами для прохождения через них болтов (8). При этом коннектор может быть выполнен любой формы и размера в зависимости от размеров
строительной конструкций и необходимого числа присоединяемых к нему балок. Крепление каждой балки (1) к коннектору (7) осуществляется посредством металлического болта (8), вкрученного в резьбовое отверстие (5) втулки (3). The connection between two or more beams is obtained by connecting the beams (1) to a metal connector (7). The connector (7) is provided with holes or vertical slots for the bolts (8) to pass through. In this case, the connector can be made in any shape and size, depending on the dimensions. building structures and the required number of beams attached to it. The fastening of each beam (1) to the connector (7) is carried out by means of a metal bolt (8) screwed into the threaded hole (5) of the bushing (3).
Предлагаемый узел соединения строительных конструкций может быть простым и удобным в монтаже и обеспечивает повышение прочности и несущей способности соединения деревянных балок при строительстве структур трехмерных соединений для кровельных перекрытий.
The proposed joint of building structures can be simple and easy to install and provides an increase in the strength and load-bearing capacity of the connection of wooden beams in the construction of structures of three-dimensional connections for roofing.
