Una de las secciones del perno tiene formadas al menos tres roscas de tornillo diferentes de una manera equiespaciada para que se pueda fijar así firmemente a la pared o tablero sin sesgarse, y las roscas de tornillo diferentes tienen diferentes profundidades de rosca para recoger los residuos de cemento generados durante el proceso de instalación y de extrusión, lo que crea un mayor efecto de fijación. Al no producirse expansión, la pared o tablero no se agrieta, y puede acortarse el intervalo entre los agujeros de construcción. En consecuencia, puede reducirse las áreas de anclaje no utilizables cerca de las esquinas de la pared, y puede incrementarse el número de agujeros de construcción en un área unitaria dada. El tornillo de anclaje de la invención puede retirarse también fácil y cómodamente para facilitar la construcción.In view of the above disadvantages, the object Primary of the invention is to provide an anchor screw perfected that has a polygonal flange (or a cavity polygonal) for fixing use and a bolt that has a section upper a lower section forming respectively on them Screw threads of different specifications. One of the Bolt sections have at least three screw threads formed different in an equally spaced way so that it can be fixed like this firmly to the wall or board without skewing, and the threads of Different screw have different thread depths for collect cement waste generated during the process of installation and extrusion, which creates a greater effect of fixation. When there is no expansion, the wall or board is not cracks, and the interval between holes can be shortened building. Consequently, anchoring areas can be reduced not usable near the corners of the wall, and can increase the number of construction holes in an area Unitary given. The anchor screw of the invention can also withdraw easily and comfortably to facilitate building.

Con referencia a las figuras 2 y 3, el tornillo 3 de la invención incluye principalmente una brida poligonal 31 para uso de fijación (la brida puede ser sujetada por una llave general para operaciones de giro y de fijación). La caña del tornillo 3 incluye una sección superior y una sección inferior para formar respectivamente un perno superior 32 y un perno inferior 33 que tienen respectivamente roscas de tornillo de especificaciones diferentes. La brida poligonal 31 puede localizarse entre el perno superior 32 y el perno inferior 33. El perno inferior 33 tiene formadas tres roscas de tornillo diferentes 331, 332 y 333 (el número de roscas de tornillo puede ser tres, cinco o similar) por lo que cada avance es tres veces el del paso (esto es para la realización de roscas triples). Además, los bordes de tornillo 3310, 3320 y 3330 de las roscas de tornillo 331, 332 y 333 tienen alturas respectivamente diferentes (también llamadas profundidad de rosca) h1, h2 y h3. Por consiguiente, cuando se fija el perno inferior 33 en un agujero de construcción 11 de una pared de cemento (como se muestra en la figura 5), las tres roscas del tornillo 331, 332 y 333 están separadas una de otra de una manera equidistante (esto se basa en la realización de roscas triples como ejemplo, véase también la figura 4) y las roscas de tornillo 331, 332 y 333 se localizan en un intervalo angular de 120° una con relación a otra. En la sección transversal hay tres líneas tangentes de rosca de tornillo equidistantes, por lo que se puede proporcionar un efecto de equilibrio para mantener el perno firmemente posicionado sin sesgado. Además, como las alturas h1, h2 y h3 de los bordes de tornillo 3310, 3320 y 3330 de las roscas de tornillo 331, 332 y 333 son diferentes, cuando se fijan los bordes de tornillo 3310, 3320 y 3330 dentro del agujero de construcción 11 (un agujero de construcción 11 tiene en general un diámetro D1 que está comprendido entre el diámetro pequeño D del perno inferior 33 y el diámetro externo de la altura más pequeña h1, es decir, D1<D + 2h1), los bordes de tornillo pueden recoger los residuos de cemento extruidos para generar un efecto de fijación más resistente. Por otro lado, como no hay expansión, la pared o tablero no se agrieta. Se puede acortar por tanto el intervalo entre los agujeros de construcción. En consecuencia, se puede reducir las áreas de anclaje no utilizables cerca de las esquinas de la pared, y el número de agujero de construcción puede incrementarse en una unidad de superficie dada. El tornillo de anclaje de la invención puede retirarse también con mayor facilidad y conveniencia para facilitar la construcción.With reference to figures 2 and 3, screw 3 of the invention mainly includes a polygonal flange 31 for fixing use (the flange can be held by a general wrench for turning and fixing operations). The screw shank 3 includes an upper section and a lower section to form respectively an upper bolt 32 and a lower bolt 33 which they have specifications screw threads respectively different. The polygonal flange 31 can be located between the bolt upper 32 and lower bolt 33. Lower bolt 33 has formed three different screw threads 331, 332 and 333 (the number of screw threads can be three, five or similar) per what each advance is three times that of the step (this is for the realization of triple threads). In addition, screw edges 3310, 3320 and 3330 of screw threads 331, 332 and 333 have respectively different heights (also called depth of thread) h1, h2 and h3. Therefore, when the bolt is fixed bottom 33 in a construction hole 11 of a cement wall (as shown in Figure 5), the three threads of screw 331, 332 and 333 are separated from each other in an equidistant manner (This is based on the realization of triple threads as an example, see also figure 4) and screw threads 331, 332 and 333 they are located in an angular range of 120 ° one in relation to other. In the cross section there are three tangent thread lines equidistant screw, so you can provide a balancing effect to keep the bolt firmly positioned without bias In addition, as the heights h1, h2 and h3 of the edges of screw 3310, 3320 and 3330 of screw threads 331, 332 and 333 they are different, when screw edges 3310, 3320 and 3330 inside construction hole 11 (a hole of construction 11 generally has a diameter D1 which is comprised between the small diameter D of the lower bolt 33 and the diameter external of the smallest height h1, that is, D1 <D + 2h1), the Screw edges can collect extruded cement waste to generate a more resistant fixing effect. On the other hand, As there is no expansion, the wall or board does not crack. It can therefore shorten the interval between construction holes. Consequently, you can reduce anchor areas not Usable near the corners of the wall, and the number of construction hole can be increased by one unit of given surface. The anchor screw of the invention can also withdraw more easily and conveniently to facilitate construction
Véase las figuras 6 y 7 para otra realización de la invención. El tornillo 4 incluye una sección superior y una sección inferior que forman respectivamente un perno superior 42 y un perno inferior 43 de diferentes especificaciones de rosca de tornillo. El perno inferior 43 tiene roscas triples con diferentes alturas de borde de tornillo (igual que la realización mostrada en la figura 2). Sin embargo, la brida poligonal 41 para uso de fijación se localiza en el extremo de arriba del perno superior 42 (es decir, el perno expuesto fuera del agujero de construcción, y la brida poligonal 41 tiene un diámetro externo menor que el diámetro del perno superior 42 para permitir el montaje de objetos externos sobre el perno superior 42 sin impedimento).See Figures 6 and 7 for another embodiment of the invention. Screw 4 includes an upper section and a lower section that respectively form an upper bolt 42 and a lower bolt 43 of different thread specifications screw. The bottom bolt 43 has triple threads with different screw edge heights (same as the embodiment shown in Figure 2). However, the polygonal flange 41 for use of fixing is located at the top end of the upper bolt 42 (i.e. the bolt exposed outside the construction hole, and the polygonal flange 41 has an external diameter smaller than the diameter of upper bolt 42 to allow mounting of objects external on the upper bolt 42 without impediment).
Véase las figuras 8 y 9 de otra realización de la invención. El tornillo 5 incluye una sección superior y una sección inferior que forman respectivamente un perno superior 52 y un perno inferior 53 de diferentes especificaciones de rosca de tornillo. El perno inferior 53 tiene roscas triples con diferentes alturas de borde de tornillo (igual que la realización mostrada en la figura 2). Sin embargo, la brida poligonal para uso de fijación ha sido modificada para convertirla en una cavidad hundida poligonal 51 formada en el extremo de arriba del perno superior 52 que puede ser cogida con una llave apropiada para uso de fijación.See Figures 8 and 9 of another embodiment of the invention. Screw 5 includes an upper section and a section lower respectively forming a upper bolt 52 and a bolt Bottom 53 of different screw thread specifications. He bottom bolt 53 has triple threads with different heights of screw edge (same as the embodiment shown in the figure 2). However, the polygonal flange for fixing use has been modified to turn it into a polygonal sunken cavity 51 formed at the top end of the upper bolt 52 which can be caught with an appropriate key for fixing use.
