Abstract

"FIXADOR DE EXPANSãO AUTO-PERFURANTE" Trata-se de um fixador de expansão autoperfurante, constituído de um cilindro pontiagudo em uma de suas extremidades e uma flange na outra. Existe um rasgo longitudinal que vai do lado pontiagudo até o início da flange, dividindo esta parte do cilindro em duas faces. Na flange existe um orifício onde deve ser introduzido um expansor que pode ser um pino ou um parafuso. O orifício onde é introduzido o expansor torna-se menor após a flange, fazendo com que o expansor force a expansão das faces que formam o corpo do cilindro, fixando-o na superfície desejada. O "FIXADOR DE EXPANSãO AUTOPERFURANTE" pode variar de tamanho, material construtivo e modo de costrução, de acordo com as necessidades técnicas."SELF-DRILLING EXPANSION FIXER" This is a self-drilling expansion fastener, consisting of a pointed cylinder at one end and a flange at the other. There is a longitudinal groove that runs from the pointed side to the beginning of the flange, dividing this part of the cylinder into two faces. There is a hole in the flange where an expander must be inserted, which can be a pin or a screw. The hole where the expander is inserted becomes smaller after the flange, causing the expander to force the expansion of the faces that form the cylinder body, fixing it on the desired surface. The "SELF-DRILLING EXPANSION FIXER" can vary in size, construction material and construction method, according to technical needs.
