Abstract

Se divulga un sistema de empernado para usos generales en la construcción, reforzamiento estructural, fijación de elementos y otros, mediante la compresión de un material externo (1) a comprimir, que comprende una barra (2) sustancialmente cilíndrica y roscada, una primera tuerca (3) con un hilo interior pasante y completo compatible con la barra (2), donde la primera tuerca (3) comprende en uno de sus extremos un hilo exterior (4), de paso más fino que el hilo de la barra (2), y comprende además una segunda tuerca (5), con un hilo interior fino (6) y pasante en un extremo, compatible con el hilo exterior (4) de la primera tuerca (3), donde la primera tuerca (3) se enrosca mediante su hilo exterior (4) dentro del hilo interior fino (6) de la segunda tuerca, y mediante su hilo interior a la barra (2) en uno de sus extremos, con la segunda tuerca (5) enfrentando al material externo (1), para posteriormente desenroscar parcialmente la segunda tuerca (5) respecto de la primera tuerca (3), utilizando su hilo interior fino (6), comprimiendo el material externo (1) hasta lograr una tensión deseada de la barra (2) y una compresión deseada del material externo (1).A bolting system for general uses in construction, structural reinforcement, fixing elements and others is disclosed, by means of the compression of an external material (1) to be compressed, which comprises a substantially cylindrical and threaded bar (2), a first nut (3) with a through and complete inner thread compatible with the bar (2), where the first nut (3) comprises at one of its ends an outer thread (4), with a finer pitch than the thread of the bar (2 ), and also comprises a second nut (5), with a fine inner thread (6) and through at one end, compatible with the outer thread (4) of the first nut (3), where the first nut (3) is threaded through its outer thread (4) into the fine inner thread (6) of the second nut, and through its inner thread to the bar (2) at one of its ends, with the second nut (5) facing the outer material ( 1), to subsequently partially unscrew the second nut (5) from the first nut (3), using its fine inner thread (6), compressing the outer material (1) until achieving a desired tension of the bar (2) and a desired compression of the outer material (1).
