Definitions

  • This invention relates to a prop for construction work of the type used for the temporary support of concrete structures and which has telescopic members which can be moved at will for the purposes of adjusting to a desired height.
  • This invention is based on forming an internal spring in the internal tube of the prop from a flat strip of steel bent into a substantially "V" shape, the ends of which have bent lips in the form of approximately circular segments projecting through transverse grooves in the tube, which is very easy to manufacture.
  • the new prop is further combined with a unitary sleeve body having a handle and a top flange, eliminating any welding and added pieces.
  • the bent lips in the shape of circular segments of the internal V-shaped spring abut against the top flange of the unitary sleeve body.
  • the new unitary sleeve will be made by casting materials providing sufficient strength and mouldability to achieve the relatively complex shape of this sleeve and handle member.
  • the new unitary sleeve is also characterised in that it has means to permit easy cleaning of the internal thread, comprising one or more longitudinal channels which interrupt the threads and which because of their width do not impede proper fine adjustment by means of the said thread, while on the other hand permitting the easy removal of dust, waste materials, etc., which habitually accumulate in such members on site.
  • the prop to which this invention relates has original features in the upper and lower plates which are attached to the extremities of the tubular body of the prop merely through cold deformation by cramping and swaging.
  • the prop to which this invention relates has an internal tubular member -1- with its threaded upper end -2- embedded in a combined sleeve member formed by tubular member -3- which through its thread -4- engages the thread -2- of tubular member -1- and from whose outer surface there extend handle members -5- and -6-, constructed as a single piece, having at the top a flange or top -7- which is also integral with the whole.
  • Internal tubular member -8- has diametrically opposite transverse grooves -9- and -10- designed for passage of the lips of internal spring -11-.
  • Internal spring -11- comprises a steel spring in the shape of a strip or band of material which has two limbs -12- and -13- joined below by curved portion -14- arranged in a substantially "V" shape, terminating at the top in outwardly bent lips -15- and -16-, whose outer edges -17- and -18- are preferably of a curved shape.
  • Spring -11- is fitted within internal tubular member -8- in such a way that lips -15- and -16- project through grooves -9- and -10- in such a way that edges -17- and -18- offer a large contact surface area when they abut against the upper flange of the sleeve, to dissipate impact energy without damaging the prop.
  • manufacture of the prop assembly is very much simplified with respect to the spring, which is merely a flat strip of material, that is a cut and bent steel spring, and likewise transverse grooves -9- and -10- in the external tube, which are very easy to manufacture.
  • construction of the sleeve, handle and upper flange assembly as a single casting provides appreciable advantages in manufacture and assembly, resulting in more effective functioning of the prop, a longer service life and substantial savings in manufacture.
  • the prop to which this invention relates provides for formation of the foot -19- and the top part -20- of the same in a new and rational way which makes it possible to avoid welding, through plates pressed directly onto the tubular member, as may be seen in the detail in Figure 7 which shows the bottom part of tubular member -1- comprising a base plate -21- having a central opening in which the bottom end of tubular member -1- is fitted by cold cramping deformation and pressing forming a cramped zone -22- of substantially doughnut structure cramped at the edge -23- of the central opening and plate -21-, supplemented with an outwardly transversely bent zone in the form of a flange -24- which bears against the upper edge of the said edge -23-, making it possible to apply loads between the plate and the tube.
  • the base plates can be formed without any need for welding and with great strength and durability.
  • top end -20- construction of the top end is similar to that described, merely in an inverse arrangement as regards the positioning of top tube -8- and upper plate -25-.
  • the pin of the prop has a special structure which essentially comprises two successive U-shaped half loops -27- and -28- arranged, as seen in plan, opposite each other and in such a way that the inner arm -29- of loop -27- passes through tubular member -8- to set the desired height, while as seen in side view loop -28- is at an obtuse angle with respect to loop -27-.
  • the extremity of external arm -30- of loop -28- ends in an extremity -31- bent into a right-angle which partly encloses the outside of loop -27-. Damage to and/or breakage of the pin and the opening, and loss of the pin, especially as a result of being dropped, is avoided in this way.
  • This invention also provides for improvements in sleeve member -3-, the inner thread -4- of which has longitudinally one or more longitudinal grooves -26- which make it possible for particles of dirt which may enter the thread from the site, and which frequently give rise to problems for the versions of prop sleeves of the type currently known, can be automatically discharged.
  • FIG 11 which illustrates sleeve -3-
  • base member -32- has a projecting collar -34- of a generally cylindrical shape with openings -35- and -36- designed to receive the bottom projections -37- and -38- of cap -33- in the working position of the prop, and it will be seen that the bottoms of these notches -35- and -36- each have small projections -39- and -40- to prevent incorrect assembly.
  • Wings -41- and -42- of base member -32- have an asymmetrical shape with a straight side -43- and an extensively curved side -44-, preventing incorrect mating with that base member.
  • cap -33- has bottom projections -37- and -38-, the bottom edges of which have a pointed shape, for example edge 45.
  • upper edges -46- and -47- of cylindrical collar -34- have an inclined structure to assist the retaining movement.
