Description
DISPOSIÇÃO CONSTRUTIVA EM PARAFUSO DE AUTOEXPANSÃO CAMPO TÉCNICO [001] O seguinte relatório descritivo para modelo de utilidade se refere à disposição construtiva em parafusos de autoexpansão, onde a manga de expansão apresenta uma coroa que se expande ao ser roscado o parafuso, deixando-o preso no talhado feito, sendo que essa coroa apresenta-se invertida em relação aos parafusos usuais.TECHNICAL FIELD CONSTRUCTIVE SCREW ARRANGEMENT [001] The following descriptive report for utility model refers to the constructive arrangement on self-expanding screws, where the expansion sleeve has a crown that expands when the screw is threaded, leaving it locked. in the carving done, and this crown is inverted in relation to the usual screws.
ESTADO DA ARTE [002] Parafusos de autoexpansão por anel é o tipo de ancoragem mais utilizada na atualidade para equipamento de escaladas, chamado familiarmente por parabolt (marca). Existem em diferentes tamanhos e diâmetros, inclusive com o dobro da expansão (dois anéis). Para colocá-lo, o talhado (furo) é feito perpendicular à rocha e do mesmo diâmetro que o parafuso deve introduzir. Assim que ajustado, o anel no seu interior se expande imediatamente ao ser apertado, dessa forma o parafuso só deve associar ao torque uns poucos fios de rosca até finalizar o aperto (chegar ao aperto ideal), um exemplo desse tipo de parafuso está mostrado no documento US 3750519 que descreve um parafuso de ancoragem com manga de expansão.ART STATUS [002] Self-expanding ring bolts is the most commonly used type of anchor for climbing equipment, commonly known as parabolt (brand). They come in different sizes and diameters, including double expansion (two rings). To place it, the cut (hole) is made perpendicular to the rock and of the same diameter as the screw should enter. Once adjusted, the ring inside expands immediately upon tightening, so the screw should only attach a few threads to the torque until tightening (reaching the optimal tightness), an example of this type of screw is shown in US 3750519 describing an expansion sleeve anchor bolt.
DISCUSSÃO [003] Os parafusos de autoexpansão conhecidos apresentam a manga de expansão que se expande no sentido direto do tracionamento feito pelo parafuso. A manga de expansão proposta realiza essa expansão no sentido contrário ao tracionamento feito pelo parafuso, com isso a coroa abre no sentido contrário.DISCUSSION Known self-expanding screws have the expansion sleeve that expands in the straight direction of the screw pull. The proposed expansion sleeve performs this expansion in the opposite direction to the screw pull, thus the crown opens in the opposite direction.
SUMÁRIO [004] Assim, devido às considerações pertinentes ao estado da arte anteriormente discutido é um dos objetivos do presente modelo de utilidade, o desenvolvimento de um parafuso de autoexpansão que apresenta manga de expansão dotada de coroa invertida. Esse parafuso permite maior aderência e resistência na fixação.Thus, due to the prior art considerations discussed above, it is one of the objectives of the present utility model to develop a self-expanding screw having an inverted crown expansion sleeve. This screw allows for greater grip and strength in attachment.
DESCRIÇÃO [005] A caracterização do presente documento para modelo de utilidade é feita por meio de desenhos representativos da disposição construtiva aplicada em parafuso de autoexpansão, de tal modo que o objeto possa ser integralmente reproduzido por técnica adequada, permitindo plena caracterização da funcionalidade do objeto pleiteado. [006] A partir das figuras elaboradas que expressam a melhor forma ou forma preferencial de se realizar o produto ora idealizado, se fundamenta a parte descritiva do relatório, através de uma numeração detalhada e consecutiva, onde esta esclarece aspectos que possam ficar subentendidos pela representação adotada, de modo a determinar claramente a proteção ora pretendida. [007] Estas figuras são meramente ilustrativas, podendo apresentar variações, desde que não fujam do inicialmente pleiteado. [008] Neste caso se tem que: [009] - A figura 1 mostra o parafuso e a manga de expansão com a coroa invertida sem estar expandida e; [0101 - A figura 2 mostra a manga inserida dentro do concreto com a coroa invertida, revelando como ela se comporta ao ser expandido pelo parafuso. [011] Uma forma preferencial de realização do modelo proposto mostra um parafuso sextavado de rosca soberba (1) e uma manga de expansão (2), sendo que se insere a manga (2) dentro do talhado feito no concreto (3), de tal modo que a coroa (4) fique invertida, ou seja, os raios virados para fora (5), sendo que ao se atarraxar o parafuso (1) na manga (2) sua expansão se dá por intermédio dos ditos raios (5) que vão se opor ao movimento de retirada do parafuso. REIVINDICAÇÃO:DESCRIPTION [005] The characterization of this document for utility model is made by means of representative drawings of the constructive arrangement applied in self-expanding screw, such that the object can be fully reproduced by proper technique, allowing full characterization of the functionality of the object. claimed. From the elaborated figures that express the best way or preferential way to realize the product idealized now, the descriptive part of the report is based, through a detailed and consecutive numbering, where it clarifies aspects that can be understood by the representation. clearly determined the intended protection. [007] These figures are for illustration purposes only and may vary as long as they do not depart from the original claim. [008] In this case one has to: [009] - Figure 1 shows the screw and the expansion sleeve with the crown inverted without being expanded and; [0101 - Figure 2 shows the sleeve inserted into the concrete with the inverted crown revealing how it behaves when expanded by the screw. [011] A preferred embodiment of the proposed model shows a superb threaded hexagon screw (1) and an expansion sleeve (2), with the sleeve (2) being inserted into the groove made of concrete (3) of such that the crown (4) is reversed, ie the outwardly facing radii (5), whereby screw (1) on the sleeve (2) is screwed in by means of said radii (5) that will oppose the withdrawal movement of the screw.
