Abstract

"APERFEIçOAMENTOS INTRODUZIDOS EM PARAFUSO CHUMBADOR". Consiste em parafuso convencional (1) dotado de rosca soberba (1.1) e bucha bipartida (2) formada por duas castanhas (2.1 e 2.2) que possuem em sua periferia saliências (2.4) que auxiliam na sua fixação. Tendo em seu lado interno um orifício cónico (2.3) com rosca soberba (2.5), onde será inserido o parafuso (1). Em uma das castanhas (2.1) existem duas abas laterais (2.7) que na união com a outra (2.2) servem para mantê-las unidas, a outra possui alojamento (2.6) onde encaixarão estas abas (2.7). O local (3) onde ficará fixado o chumbador é preparado com um furo (3.1) onde será inserido a bucha bipartida (2), quando atarrachado o parafuso (1) as castanhas dilatam seu lado inferior, como mostra a figura 2, permitindo sua compressão nas paredes do furo (3.1) fixando o chumbador na local desejado (3)."IMPROVEMENTS INTRODUCED IN A LEAD SCREW". It consists of a conventional screw (1) equipped with a superb thread (1.1) and split chuck (2) formed by two nuts (2.1 and 2.2) that have protrusions (2.4) on their periphery that help in their fixation. Having a conical hole (2.3) with a superb thread (2.5) on its internal side, where the screw (1) will be inserted. In one of the chestnuts (2.1) there are two side flaps (2.7) that in union with the other (2.2) serve to keep them together, the other has a housing (2.6) where these flaps (2.7) will fit. The location (3) where the anchor bolt will be fixed is prepared with a hole (3.1) where the split anchor (2) will be inserted, when the screw (1) is screwed, the chestnuts expand its lower side, as shown in figure 2, allowing its compression in the hole walls (3.1) fixing the anchor in the desired location (3).
