Abstract

PERNOS DE ROCA (1). ECONÓMICOS DE FABRICAR Y EN DONDE LA CARGA DEL COMPUESTO PARA ANCLAJE ES PRESIONADO UNIFORMEMENTE Y EN FORMA CONFIABLE DENTRO DE LA CAVIDAD ALREDEDOR DEL TUBO DEL PERNO, EXISTEN EN VARIAS FORMAS, EN DONDE ES PARTICULARMENTE VENTAJOSO SI EL EXTREMO DE DESCARGA (4) ESTÁ PROVISTO CON UN CABEZAL MEZCLADOR (15), EN EL CUAL EL ORIFICIO DE SALIDA (8) REQUERIDO ESTÁ INTEGRADO. ESTE ORIFICIO DE SALIDA (8) ESTÁ PROTEGIDO POR LA FORMA DEL CABEZAL (16) DEL CABEZAL MEZCLADOR (15) EN TAL FORMA QUE UNA DESCARGA CONFIABLE DE LA MEZCLA PARA ANCLAJE ESTÁ SIEMPRE GARANTIZADA INCLUSO SI HAY PERFORACIONES AÚN SITUADAS EN EL BARRENO. ADEMÁS, EL CARTUCHO PARA ANCLAJE (7) EN LA APLICACIÓN DE PRESIÓN ES ABIERTO EN FORMA CONFIABLE RASGÁNDOLO DE TAL FORMA QUE LOS DOS COMPONENTES PASAN A LA REGIÓN DEL MEZCLADOR ESTÁTICO (9) Y SON LUEGO DESCARGADOS EN EL ESTADO MEZCLADO DE TAL FORMA QUE LA CAVIDAD (12) ALREDEDOR DEL TUBO DE PERNO (2) ES RELLENADA EN FORMA CONFIABLE.ROCK BOLTS (1). ECONOMICAL TO MANUFACTURE AND WHERE THE LOAD OF THE ANCHOR COMPOUND IS UNIFORMLY AND RELIABLY PRESSED INSIDE THE CAVITY AROUND THE BOLT TUBE, THERE ARE IN VARIOUS FORMS, WHERE IT IS PARTICULARLY ADVANTAGED (PROVIDED WITH 4 EXTREME ADVANTAGES) A MIXER HEAD (15), IN WHICH THE REQUIRED OUTLET HOLE (8) IS INTEGRATED. THIS OUTLET HOLE (8) IS PROTECTED BY THE SHAPE OF THE HEAD (16) OF THE MIXER HEAD (15) IN SUCH A WAY THAT A RELIABLE DISCHARGE OF THE ANCHOR MIX IS ALWAYS GUARANTEED EVEN IF THERE ARE STILL PUNCHES IN THE HOLE. IN ADDITION, THE ANCHOR CARTRIDGE (7) IN THE APPLICATION OF PRESSURE IS RELIABLY OPENED BY RIPPING IT IN SUCH A WAY THAT THE TWO COMPONENTS PASS INTO THE REGION OF THE STATIC MIXER (9) AND ARE THEN DISCHARGED IN THE MIXED STATE IN SUCH A WAY AS THE CAVITY (12) AROUND BOLT TUBE (2) IS RELIABLY FILLED.
