Description

Изобретение относится к строительству, а именно к соединению элементов деревянных конструкций.The invention relates to the construction, namely the connection of elements of wooden structures.

Известна конструкция стыка деревян-. ных элементов на колодках, нагелях, ⁵пластинчатых шпонках, которые осуществляют передачу усилий за счет врезания соединительных элементов в массив элементов конструкции [1]. : ...Known design joint wooden. elements on the pads, pins, ⁵ plate dowels, which carry out the transmission of forces by cutting the connecting elements into an array of structural elements [1]. : ...

Недостатками устройства являются ^υсложность изготовления стыка, необходимость изготовления соединительных элементов (колодок, шпонок), а также ослабление элементов конструкции врубками, зарезаниями и т.д. 15The disadvantages of the device are ^{υ the} complexity of the manufacture of the joint, the need for the manufacture of connecting elements (pads, dowels), as well as the weakening of structural elements by cuts, cuts, etc. fifteen

Наиболее близким по технической сущности к предлагаемому является соединение растянутых элементов при помощи стальных накладок и приваренных к ним стальных шпонок, которые 20 врезаются с двух сторон в соединяемые элементы и стягиваются болтами, при этом усилие передается стыком за счет работы древесины между шпонками И · 25The closest in technical essence to the proposed one is the connection of the stretched elements using steel plates and steel dowels welded to them, which 20 cut into two from the two sides into the connected elements and are pulled together by bolts, while the force is transmitted by the joint due to the work of the wood between the keys And 25

Недостатками данного стыка являют-. ся ослабление конструкции врубками, трудность передачи большого усилия стыком через скалывание древесины, необходимость высокой точности изго- 30 товления стыка и низкая долговечность перерезанных волокон древесины.The disadvantages of this joint are. This is due to weakening of the structure by cuts, the difficulty of transferring a large joint force through chipping wood, the need for high accuracy of the joint manufacturing and low durability of cut wood fibers.

Цель изобретения - увеличение несущей способности и надежности стыка за счет сохранения целостности волокон древесины.The purpose of the invention is to increase the bearing capacity and reliability of the joint by maintaining the integrity of the wood fibers.

Поставленная цель достигается тем, что стальные шпонки выполнены плоскими со стороны накладок и криволинейными со стороны древесины.This goal is achieved in that the steel keys are made flat from the side of the plates and curved from the side of the wood.

На чертеже изображена конструкция стыка деревянных элементов, общий вид.The drawing shows the joint design of wooden elements, a General view.

Конструкция стыка включает накладки 1, шпонки 2, болты 3 и соединительные элементы 4.The joint design includes pads 1, keys 2, bolts 3 and connecting elements 4.

В процессе эксплуатации усилие передается с накладки 1 на древесину через криволинейную шпонку 2, которая через надавливание и трение криволинейной поверхности передает продольное и касательное усилие.During operation, the force is transmitted from the lining 1 to the wood through a curved key 2, which, through pressure and friction of the curved surface, transmits a longitudinal and tangential force.

Выполнение соединения таким образом позволяет в процессе устройства стыка, не делая врубок, силой натяжения соединительных болтов достигать вмятия криволинейных шпонок в древесину без разрыва волокон.The implementation of the connection in this way allows, in the process of making a joint, without making cuts, by the force of the tension of the connecting bolts to achieve the indentation of the curved keys in the wood without breaking the fibers.

При применении данного соединения деревянных элементов достигается це3 лый ряд преимуществ:повышение надежности стыка, так как криволинейная ‘шпонка вызывает смятие древесины при разрушении вместо более опасного скалывания, которое имеет место в известном соединении, появляется возможность достижения равнопроЧности стыка и соедйняемого элемента. Простота устройства стыка не требует точной подгони шпонок, несущая способность соединенного элемента повышается, так как стык не ослабляет площадь сечения врезной шпонки, а только искривляет волокна древесины. Кроме того повышается долговечность стыка из-за отсутствия перерезанных волокон, подверженных быстрому загниванию.When applying this connection of wooden elements, a number of advantages are achieved: increasing the reliability of the joint, since the curved ‘key leads to crushing of the wood during destruction instead of the more dangerous chipping that occurs in the known connection, it becomes possible to achieve equal strength of the joint and the joined element. The simplicity of the joint device does not require precise fitting of the keys, the bearing capacity of the connected element is increased, since the joint does not weaken the cross-sectional area of the mortise key, but only bends the wood fibers. In addition, the durability of the joint is increased due to the absence of cut fibers subject to rapid decay.

Claims

The invention relates to the construction, in particular to the joining of element wood constructions. The known structures of the joint of wooden elements on the pads, lugs, lamellar keys, which transmit the force due to the embedding of the connecting elements into the array of structural elements 1. The drawbacks of the device are the difficulty of manufacturing the joint, the need to manufacture the connecting elements (pads, dowels), as well as the weakening of structural elements by cuts, notches, etc. The closest in technical essence to the present invention is the joining of stretched elements with the help of steel plates and steel dowels welded to them, which cut from both sides into the connecting elements and are bolted, while the force is transmitted by the joint due to the work of wood between dowels 2. The disadvantages of this joint are the weakening of the construction of the cut-offs, the difficulty of transmitting a large force by the joint through the chipping of wood, the need for high precision of the joint production and the low durability of cut wood fibers. The purpose of the invention is to increase the carrying capacity and reliability of the joint by maintaining the integrity of the wood fibers. The goal is achieved by the fact that steel tongues are made flat on the side of the knobs and curvilinear on the side of wood. The drawing shows the structure of the junction of wooden elements, a general view. The design of the joint includes lining 1, pins 2, bolts 3 and connecting elements 4. During operation, the force is transferred from the lining 1 to the wood through a curved key 2, which transmits a longitudinal and tangential force through pressure and friction of the curved surface. Making the joint in this way allows, in the process of arranging the joint, not to cut, the tensioning force of the connecting bolts reaches the curvature of the splines into the wood without breaking the fibers. When using this combination of wood elements, a number of advantages are achieved: an increase in the reliability of the joint, since the curved spline causes the wood to crumble when destroyed, instead of the more dangerous chipping that occurs in the known joint, it is possible to achieve equipotential bonding element The simplicity of the joint device does not require precise preparation of the keys, the carrying capacity of the connected element increases, since the joint does not weaken the sectional area of the mortise key, but only distorts the wood fibers. In addition, the durability of the joint is increased due to the absence of cut fibers subject to rapid rotting. Claims of wood elements including bolts and bolts, characterized in that, in order to increase the bearing capacity and reliability of the joint by maintaining the integrity of wood fibers, the keys are flat on the side of the plates and curvilinear on the side of wood.
