Изобретение относитс к судостроению, а именно к стыковым формованным соединени м стеклопластиков.FIELD OF THE INVENTION The invention relates to shipbuilding, namely to butt molded joints of glass-reinforced plastics.
Известно клееное соединение конструкций из стеклопластиков 1,Known glued connection of fiberglass structures 1,
Недостатком указанного соединени вл етс мала прочность, объ сн ема наличием концентраций напр жений по концам клееных швов при нагружении соединени .The disadvantage of this compound is low strength, due to the presence of stress concentrations at the ends of the glued seams when the joint is loaded.
Наиболее близким по технической сущности к предлагаемому вл етс стыковое формованное соединение стеклопластиков, содержащее соедин емые детали, приформованные накладки и клеевую прослойку 2.The closest in technical essence to the present invention is a butt molded compound of glass-reinforced plastics containing joining parts, preformed linings and adhesive layer 2.
Недостаток такого соединени заключаетс в том, что его прочность при разрыве ниже, прочности соедин емого стеклопласгека.The disadvantage of such a compound is that its tensile strength at break is lower than that of the glassglass to be joined.
Цель изобретени - повышение прочности соединени .The purpose of the invention is to increase the strength of the joint.
Указанна цель достигаетс тем, что клеева прослойка выполнена с клиновидными утолщени ми на кра х клеевого шва и в месте соединени деталей, причем толщина клеевой прослойки между зтолщени ми посто нна.This goal is achieved by the fact that the adhesive layer is made with wedge-shaped thickenings at the edges of the adhesive joint and at the junction of the parts, the thickness of the adhesive layer between thickening is constant.
Кроме того, толщина клиновидных утолщений составл ет 5-6 толщин клеевой прослойки на ширине 15-20 толщин клеевой прослойки.In addition, the thickness of the wedge-shaped bulges is 5-6 thickness of the adhesive layer at a width of 15-20 thickness of the adhesive layer.
На чертеже схематично изображено предлагаемое устройство.The drawing schematically shows the proposed device.
Стыковое формованное соединение содержит собственно соедин емые детали 1, приформированные накладки переменного сечени 2 и клеевую прослойку 3, выполне1шую с к;шновидными утолщени 1ии 4 на концах накладок и у места стыка деталей 5.The butt molded joint contains the parts to be joined 1, the forks of variable cross section 2 and the adhesive layer 3, which are formed with a K-shaped bolts 1 and 4 at the ends of the plates and at the junction of the parts 5.
Толщина клеевой прослойки между утолщени ми посто нна. Толщина же клиновидных утолщений составл ет 5-6 толщин клеевой прослойки на ширине 15-20 толщин клеевой прослойки .The thickness of the adhesive layer between the thickenings is constant. The thickness of the wedge-shaped bulges is 5-6 thicknesses of the adhesive layer at a width of 15-20 thicknesses of the adhesive layer.
Применение предлагаемого изобретени особенно в крупном пластмассовом судостроении может в значительной степени увеличить прочность и эффективность пластмассовых конструкций, так как увеличение прочности соединени , а они до насто щего времени вл ютс наиболее слабым узлом конструкции, позволит более эффективно нагружать ocijciBHbie несущие конструкции , которые могут соответственно либс легче, либо при том же весе нести большие эксплуатационные нагрузки.The application of the present invention, especially in large-scale plastic shipbuilding, can significantly increase the strength and efficiency of plastic structures, since an increase in the strength of the joint, and they are the weakest component of the structure to date, will make it possible to more efficiently load ocijciBHbie supporting structures that can respectively easier, or with the same weight to carry large operating loads.
