Para ello, las presentes mejoras prevén el engrapado entre el elemento tubular y cada pletina dotada de orificio central, mediante una disposición del reborde del elemento tubular en forma de gancho sensiblemente en "U", preferentemente dispuesto con un cierto ángulo con respecto a la vertical que abraza directamente el pliegue extremo realizado en el orificio de la pletina, de manera que existe una sensible alineación entre la pared del elemento tubular y las zonas de contacto con el pliegue de la pletina y la zona de contacto con el suelo del gancho en forma de "U" del propio elemento tubular. Mediante esta disposición se consigue una mayor facilidad de fabricación y economía por ser la manipulación del elemento tubular y de la propia pletina de mayor suavidad y menor exigencia en el material, por lo que además se asegura una mayor duración en el puntal, al desaparecer el peligro de formación de grietas con la consiguiente posibilidad de
rotura.The improvements object of the present invention refer to the constitution of the stapling between plate and tubular element so that the material is not subjected to high deformation stresses, thereby avoiding possible crack formation in certain areas. To this end, the present improvements provide for the stapling between the tubular element and each plate provided with a central hole, by means of an arrangement of the flange of the tubular element in a substantially "U" shape, preferably arranged at a certain angle with respect to the vertical which directly embraces the end fold made in the hole of the plate, so that there is a sensitive alignment between the wall of the tubular element and the contact areas with the fold of the plate and the contact area with the floor of the shaped hook of "U" of the tubular element itself. Through this arrangement a greater ease of manufacture and economy is achieved by being the manipulation of the tubular element and the plate itself of greater smoothness and less demand on the material, so that it also ensures a longer duration in the strut, when the danger of cracking with the consequent possibility of
break.

Para su mejor comprensión se adjunta, a título de ejemplo explicativo pero no limitativo, la figura 1 que muestra una sección transversal de la zona del pie de un puntal que incorpora las presentes mejoras. En dicha figura se representa una sección transversal completa.For your best understanding it is attached, by title an explanatory example but not a limitation, figure 1 that shows a cross section of the foot area of a strut that incorporates the present improvements. This figure represents a full cross section.

Tal como se aprecia en dicha figura, las mejoras objeto de la presente solicitud de Patente de Adición se refieren a la realización del reborde extremo del elemento tubular en forma de gancho (1) en la pared del elemento tubular (2) que integra el puntal, adoptando dicho elemento en forma de gancho, en el ejemplo representado, una estructura de lados (3) y (4) que forman una estructura sensiblemente en "U" dispuesta con un cierto ángulo con respecto a la vertical y comprendiendo en su interior el reborde (5) realizado en el orificio central de la pletina (6), que en el caso representado corresponde a la pletina inferior de un puntal apoyado sobre la superficie del suelo (7). El reborde (5) queda engrapado en el interior del gancho (1), presentando una estructura simple de borde doblado con respecto a la zona inmediata (8) de la pletina.As can be seen in this figure, the improvements  Subject of the present Addition Patent application refer to the realization of the end flange of the tubular shaped element hook (1) on the wall of the tubular element (2) that integrates the strut, adopting said hook-shaped element, in the example represented, a structure of sides (3) and (4) that form a substantially "U" structure arranged at a certain angle with respect to the vertical and comprising inside the flange (5) made in the central hole of the plate (6), which in the case represented, it corresponds to the lower plate of a prop supported on the ground surface (7). The flange (5) it is stapled inside the hook (1), presenting a simple folded edge structure with respect to the immediate area  (8) of the plate.

Es decir, se realiza el engrapado entre las paredes de cada uno de los extremos, superior e inferior del puntal, y el borde del orificio central de las pletinas correspondientes, por engrapado del extremo del tubo correspondiente, que es doblado en forma de gancho abierto que se prolonga directamente del elemento tubular sin plegado intermedio, comprendiendo en su interior el reborde doblado del orificio de cada una de las pletinas, disponiéndose sensiblemente en alineación una generatriz de la pared del elemento tubular, el punto de contacto sobre el exterior del reborde doblado de la pletina, el contacto de la pletina con el interior del extremo doblado en forma de gancho del elemento tubular y el punto de contacto exterior del elemento tubular sobre el suelo o superficie plana de apoyo.That is, stapling is performed between the walls of each of the ends, upper and lower of the strut, and the edge of the central hole of the plates corresponding, by stapling the end of the tube corresponding, which is folded in the form of an open hook that extends directly from the tubular element without intermediate folding, comprising inside the folded flange of the hole of each of the plates, arranged substantially in alignment a generatrix of the wall of the tubular element, the point of contact on the outside of the folded flange of the plate, the contact of the plate with the inside of the bent shaped end of hook of the tubular element and the external contact point of the tubular element on the floor or flat support surface.
