Abstract

Изобретение относитс  к машиностроению, в частности к средствам дл  анкерного креплени . Цель изобретени  - повышение надежности установки и анкеровки дюбел  в отверстии строительного элемента. Распорный дюбель содержит стержень 1 с резьбой 2 на одном конце и кольцевой проточкой 3 на другом конце. Цилиндрическа  часть 7 проточки 3 переходит в коническую часть 7. В проточке размещена втулка 4 с отогнутыми кра ми 5 продольного разреза. Кра  5 выполнены со скосами 6. Скосы направлены в сторону конической части 7 проточки стержн . Скосы позвол ют обеспечить вхождение дюбел  в отверстие базовой конструкции без разрушени  материала базовой конструкции и среза части металла втулки дюбел . После забивани  дюбел  на необходимую глубину на резьбу навинчивают крепежную гайку. Отсутствие сколов материала базовой конструкции и среза части втулки способствует повышению надежности дюбел . 1 з.п.ф-лы, 10 ил.The invention relates to mechanical engineering, in particular to means for anchoring. The purpose of the invention is to increase the reliability of installation and anchoring of dowels in the hole of the building element. The expansion bolt shield includes a rod 1 with a thread 2 at one end and an annular groove 3 at the other end. The cylindrical part 7 of the bore 3 passes into the conical part 7. A bushing 4 with bent edges 5 of a longitudinal section is placed in the bore. Edge 5 is made with bevels 6. Bevels are directed towards the conical part 7 of the groove of the rod. The bevels allow the dowel to enter the hole of the base structure without destroying the material of the base structure and cutting off a part of the metal of the dowel sleeve. After driving the dowel to the required depth, the mounting nut is screwed onto the thread. The absence of chipping of the material of the basic design and the cut-off of the part of the sleeve contributes to the reliability of the dowel. 1 hp ff, 10 ill.

Формула изобретенияClaim 1. Распорный дюбель,содержащий стержень с резьбой на одном конце и кольцевой проточкой на другом конце, имеющей цилиндрический и конический участки, и размещенную в проточке стержня втулку с продольным разрезом, при этом кромки втулки, образующие продольный разрез, отогнуты в направлении от стержня, отличающийся тем, что, с целью повышения надежности установки и анкеровки дюбеля в отверстии строительного элемента, кромки втулки, образующие продольный разрез, выполнены со скосами со стороны конического участка кольцевой проточки стержня, причем отношение размера каждого из скосов по торцу втулки к размеру вдоль втулки составляет 0,1 - 1,1.1. An expansion dowel comprising a rod with a thread at one end and an annular groove at the other end having cylindrical and conical sections, and a sleeve with a longitudinal section located in the groove of the rod, while the edges of the sleeve forming a longitudinal section are bent away from the rod, characterized in that, in order to increase the reliability of installation and anchoring of the dowel in the hole of the building element, the edges of the sleeve forming a longitudinal section are made with bevels from the side of the conical section of the annular groove of the rod, moreover, the ratio of the size of each of the bevels along the end of the sleeve to the size along the sleeve is 0.1 - 1.1. 2. Дюбель поп. 1.отличающийся тем, что скосы втулки имеют радиусную форму с вогнутостью, обращенной в тело втулки.2. Dowel pop. 1. characterized in that the bevels of the sleeve have a radial shape with a concavity facing the body of the sleeve.
