Definitions
- Props are vertical support elements whose height can be adjusted, normally used in construction, comprised of a vertical exterior base tube, known as the lower shaft, which has a support base at its lower end and an interior tube, or upper shaft, that is removable to a lesser or greater extent from the lower shaft to adapt the length of the prop to the distance between the surfaces or elements to be supported by the prop, such as formwork elements.
- a vertical exterior base tube known as the lower shaft
- an interior tube, or upper shaft that is removable to a lesser or greater extent from the lower shaft to adapt the length of the prop to the distance between the surfaces or elements to be supported by the prop, such as formwork elements.
- a device to aid the unloading of props is disclosed in document ES 2140280, wherein it provides a sliding holder on the prop shaft, that is supported by the adjusting nut and which has two indentations diametrically opposite one other, each one having on one of its sides a sloping step, the bottom of the indentation being rounded, adapted to receive the prop pin.
- the device is complemented by another part, a sliding cylindrical device on the exterior of the prop shaft, which holds different diametrically opposite extensions, which can fit, for the operative position of the prop, in the holder indentations, preventing the accidental falling of the pin therein.
- the first projection and second projection of each annular body have respectively, in the sides opposite the transversal protuberances, a first and a second bevelled surface parallel to the surfaces of the opposite interior faces of the two straight sides of the intermediate unloading wedge, so that said bevelled surfaces have guide devices for the intermediate unloading wedge when this slides between the two annular bodies, at the same time that said bevelled surfaces of the same body are guided by the vertical end stop portions of the bases of the other annular body to which it is attached.
- at least the first projection of each annular body is included in the opposite face of the face with the transversal protuberance of a third bevelled surface, which is attached to the first bevelled surface.
- Fig. 2 is a side view of the section of the prop of Fig. 1 ;
