Definitions

  • ABSTRACT A support beam consisting of two telescopically interfitting tubular rods provided with an adjusting and locking device wherein the outer rod carries a support collar with opposite lateral extensions and the inner rod carries two sleeves, the upper sleeve being inclined and having opposite horizontal extensions engaged on their outer end by the lateral extensions of the support collar to exert a pressure on this sleeve causing pivoting movement therein to bear against the inner rod in a locking manner, the second sleeve having conventional means to lock it in position on the inner rod.
  • the present invention relates to an adjustable support beam or prop for supporting ceiling, wall and frame structures of the type generally used in the construction of buildings.
  • the support beam according to the invention comprises two tubular telescopically interfitting rods wherein the inner rod is slidably received in the outer rod and a device for adjusting and maintaining the position of the rods relative to each other in setting the desired height of the beam.
  • This device consists basically of a collar welded to the outer rod and of two sleeves which are slideably mounted over the inner rod.
  • the known beams provided with screw devices for adjusting the height of the beam permit a gradual adjustment of the height but they have the disadvantage that they tend to accumulate rust so that the screw can be turned frequently only by applying considerable force and expending an excessive amount of time.
  • the present invention concerns a device which provides a gradual or stepless adjustment of the height without the need of a screw arrangement.
  • the structural simplicity and working precision of the beams according to the invention permit a saving of maintenance and time.
  • the handling and operation of the new beams is extremely simple and requires no trained workers.
  • FIG. 1 is a side view of the vertical support beam according to the invention in combination with the auxiliary triangular top support.
  • FIG. 2 represents the direction of the active force in the upper sleeve during the supporting action of the beam or during transporting of the beam.
  • FIG. 3 shows an example of an application of the novel beam with and without the triangular top support.
  • FIG. 4 is a diagrammatic view of a cross-section through the novel beam along the line A-B in FIG. 1.
  • FIG. 5 shows the triangular top support
  • FIG. 6 shows on a larger scale a cross-section along line IIIIII of FIG. 5.
  • the support beam according to the invention consists of an inner rod or base elementl which is received in the outer rod 2 of larger diameter in a telescopic manner.
  • a circular flange or protective hood 3 is attached to the lower part of rod 2 as by welding in order to prevent a soiling of the adjusting device by dust particles, cement, mortar or the like.
  • This adjusting device consists of a collar 4 which is preferably welded to the lower end of the rod 2 and which presents at one side a support extension 5 which.
  • Two sleeves 8 and 9 are slidably mounted around the inner rod 1.
  • the sleeve 8 is inclined and presents two oppositely disposed horizontal extensions 7 and 12.
  • the extension 12 serves to lock the beam in the working position by means of the guides 6 on the collar 4 which receive the extension 12 so that the sleeve is at all times in the correct position and permits the effect of one of the two directional forces shown in FIG. 2.
  • the extension 16 of collar 4 bears against the extension 7 of sleeve 8 to exert a force which is opposite to the force described above and causes a locking of the two rods.
  • the extension 7 also assists in setting the correct position of the guides 6 and prevents a release or sliding of the extension 12 out of the guides 6 of the collar 2.
  • the lower sleeve 9 has a lateral grooved extension 14 directed slightly upwardly under the extension 12 of -sleeve 8. This sleeve has at one side a threaded hole with a setting screw 21.
  • the beam has at its lower end a base plate 11 and at its upper end a bearing support 10.
  • the rods 1 and 2 have at their opposite ends inner and outer side collars 22 which avoid an excessive amount of play and confer the required rigidity to thebeam. They also facilitate the sliding action when the contact surface between the rods 1 and 2 becomes smaller and prevent a separation of the two rods 1 and 2 upon pulling them apart.
  • the lever 13 placed on the extension 7 of the sleeve 8 may also be extended by means of a tubular extension piece 15. Holes 19 are provided in the bearing support 10 for securing'the beam by means of pins or the like to the frame work to be carried by the beam.
  • the upper rod 2 is provided also under the plate 10 at a suitable distance with a welded sleeve 24 which has upwardly inclined extensions 25 for anchoring the beam in combination with the outwardly inclined stays 28 of the triangular support.
  • This support consists of the two lateral stays 28 and the horizontal bar 27 which constitutes a bearing surface.
  • the free ends of the lateral stays 28 project into the extensions 25 of the sleeve 24 around rod 2 and thus impart strength to the unit.
  • the horizontal bar 27 is provided with pins 29 which fit into the holes 19.
  • a slide bushing 26 is provided which presents on the upper side an extension 31 which has one or more holes 30 in order to attach the bar to the frame work and thus prevents a falling of the beam.
  • the beam is generally used as shown in FIG. 3.
  • the safety screw 21 As soon as the beam is securely set in place the safety screw 21 is screwed strongly against the rod 1. In this manner the device is locked and the sleeve 9 serves as holding safety. In order to collapse the beam the safety screw 21 is released so that the sleeve 9 may slide downwardly. By a force on the lever 13 between the extension 7 of sleeve 8 and the extension 17 of the collar 4 the sleeve 8 assumes again its vertical position and slides downwardly.
  • the triangular support is secured to the beam by placing it on the rod 2 and sliding it downward until the free ends 28 wedge between the rod 2 and the extensions 25 of the collar 24.
  • the pins 29 are simultaneously inserted into the holes 19 of the plate and bushings 26 are moved until they correspond with the holes provided in the structure to be supported so that this structure may be secured to the beam.
  • An adjustable support beam comprising two telescopically arranged tubular rods wherein an inner rod (1) is'received telescopically in an outer rod (2) in sliding relationship, and an adjusting and locking device for fixing the rods in position relative to each other, said device consisting of a support collar (4) secured to said other red (2), and of an upper sleeve (8) and a lower sleeve (9) mounted for sliding movement along said inner rod (1), said support collar (4) having opposite extensions (5,17), said upper sleeve (8) having an inclined configuration with opposite extensions (7,12) said lower sleeve (9) having means to lock it on said inner rod whereby said extension (5) of said support collar bears in the supporting position of said adjustable beam on the outer extremity of said extension (12) on said upper sleeve to generate a pivotin action to lock said upper sleeve on said inner rod, sat extension (17) on said support collar (4) having a portion (16) projecting inwardly under said extension (7) on said upper
  • An adjustable support according to claim 4 wherein a ring member is fixed to the outer end of said inner rod (1) and to the inner end of said outer rod (2) to prevent separation of said rods.
  • An adjustable support according to claim 5 comprising a collar (24) fixed to the upper end of said outer rod provided with upwardly and outwardly directed extensions (25) and a triangular support consisting of a horizontal top bar connected at each extremity to two downwardly and inwardly directed stays, the free ends of said stays engaging behind said extensions (25) on said collar (24).
