Definitions

  • the present invention relates to a joint between two objects to be joined together, such as reinforced concrete pillars, said joint comprising
  • each pillar to be joined has at its one end four guiding and locking spigots provided with a transverse hole, which fit into corresponding cavities provided at the end of the opposite pillar when the pillars are set end to end to form extensions of each other.
  • the butt joint is locked by inserting locking splines laterally through the transverse holes in the pillar ends and through the holes provided at a corresponding position in the guiding and locking spigots.
  • this method of making a joint has proved to be difficult and laborious in practice.
  • transverse holes in the pillar ends and the holes of the guiding and locking spigots are not always properly aligned, so it is difficult to drive the transverse locking splines into position.
  • one or more of the locking splines of the joint are left out, so a weak butt joint is formed between the pillars.
  • the joining element at the end of a pillar to be extended comprises a round spigot, which is fitted into a round cavity at the end of another pillar, said cavity being provided with an annular groove and an annular spring.
  • the end of the spigot is conically shaped so that, when inserted into the cavity, it opens and strains the annular spring in the cavity.
  • the object of the present invention is to achieve a butt joint for pillars that does not have the above-described disadvantages.
  • the joint of the invention for joining two objects is characterized in that the groove of the joining element of at least one of the objects to be joined is provided with a wedge-like part on which the spring-like locking element is wedged.
  • a preferred embodiment of the joint of the invention is characterized in that the annular groove in the projecting part of the first joining element has a wedge-shaped cross-section so that at least one of the side walls of the groove forms an element, such as a conical surface, that produces a wedging effect on the spring-like locking element.
  • a second preferred embodiment of the joint of the invention is characterized in that the spring-like locking element is a severed annular spring having a rectangular cross-section.
  • a fourth preferred embodiment of the joint of the invention is characterized in that the spring-like locking element is a severed annular spring of circular cross-section.
  • a further preferred embodiment of the joint of the invention is characterized in that the annular groove in the cavity has a wedge-shaped cross-section such that at least one of the side walls of the groove forms an element, such as a conical surface, that produces a wedging effect on the spring-like locking element.
  • Fig. 1 illustrates a situation where two reinforced concrete pillars 10a and 10b are being joined together end to end, with the pillar ends brought close to each other but still remaining apart.
  • the principal material of the pillars 10a and 10b is concrete 11, in addition to which they also contain numerous steel reinforcements as is known in the art, which are not shown.
  • Fig. 1 presents a detailed illustration of the structure of the joining elements 20a and 20b.
  • Each joining element 20a and 20b comprises an end plate 21a and 21, an edge collar 22a and 22b welded on it and anchor bars 23a and 23b welded to the end plates 21a and 21.
  • the joining element 20a of the reinforced concrete pillar 10a shown above the other one in Fig. 1 comprises a cylindrical projecting part 30 welded to the end plate 21a and having an annular groove 31 in the outer surface of its cylinder barrel.
  • the inner end of the cylinder 30 is closed by a bottom plate 32.
  • the joining element 20b of the reinforced concrete pillar 10b shown below the other one in Fig. 1 comprises a cylindrical cavity 40 welded to the end plate 21b and having an annular groove 41 in the inner surface of its cylinder barrel.
  • This cylinder 40 is provided with a bottom plate 42.
  • the extremity of the cylindrical projecting part 30 is shaped as a conical surface 33, which, when the reinforced concrete pillars 10a and 10b are being joined together, causes the severed annular spring 50 in the groove 31 of the cavity 40 to open until the spring falls into the groove 31 of the projecting part 30, locking the joint between the joining elements 20a and 20b and therefore the joint between the reinforced concrete pillars 10a and 10b.
  • Fig. 1 it can be seen that it is possible to add a suitable number of reinforcing rods to the circumference of the joining elements 20a and 20b in accordance with the strength requirements regarding the joint between the reinforced concrete pillars 10a and 10b.
  • Fig. 2 presents the structure of the joining elements 20a and 20b of reinforced concrete pillars 10a and 10b in vertical section.
  • the projecting cylindrical part 30 attached to the end plate 21a of the upper pillar 10a has a conical end 33 and an annular groove 31. It can be seen from the figure that one 34 of the side walls of the annular groove 31 is inclined, forming an angle ⁇ with a plane perpendicular to the longitudinal axis of the cylinder 30. Since the projection 30 is a round cylinder, the inclined wall 34 forms a conical surface.
  • the angle ⁇ preferably has a magnitude of only a few degrees. An inclination of e.g.
  • the cylinder 40 of the joining element 20b of the lower pillar 10b is provided with an internal annular groove 41 of rectangular cross-section, with a severed annular spring 50 of rectangular cross-section placed in the groove.
  • a and b indicate the distances from the edges of the annular grooves 31 and 41 to the stop faces of the reinforced concrete pillars 10a and 10b to be placed against each other. In manufacture, these measurements are essential to flawless functioning of the joining elements 20a and 20b. To allow the annular spring 50 to be effectively locked against the conical surface 34, measurement a must be smaller than or equal to measurement b.
  • Fig. 3 shows the reinforced concrete pillars 10a and 10b of Fig. 2 joined together, with the annular spring 50 latched in the groove 31 of the projecting part 30 of the joining element of the upper reinforced concrete pillar 10a. Since the annular spring 50 was expanded by the conical surface 33 of the projecting part 30 during the insertion movement, in the locked state of the joint the annular spring 50 is still exerting compression. Thus, the annular spring 50 is wedged against the conical surface 34 of the groove 31. When the pillar thus extended is jolted by impacts applied to the end of the upper pillar, each impact will cause the annular spring 50 to be more and more tightly wedged against the conical surface 34, a very firm joint being thus formed.
  • Fig. 4 presents an embodiment in which a more effective wedging of the annular spring 50 as the conical surface 34 is additionally ensured by using screws 51a and 51b that press the annular spring towards the bottom of the groove 31.
  • Fig. 5 presents a diagrammatic vertical section of a joint connecting two objects, in which the cylindrical projecting part 30 has been pressed into the cylindrical cavity of the other object.
  • both the groove 31 of the cylindrical projecting part 30 and the annular spring 50 have a wedge-shaped cross-section, i.e. both have conical surfaces, which are placed against each other.
  • the annular spring 50 is wedged still more effectively into the groove 31, interlocking the projecting part 30 and the cavity 40 of the joining elements.
  • Fig. 6 presents an alternative annular spring 50, according to which the annular spring 50 has a circular cross-section.
  • Fig. 7 presents a joint between a reinforced concrete pillar 10 and a rock shoe 60 in vertical section.
  • the structure of this joint fully corresponds to the above-described joint between two pillars.
  • a rock shoe 60 as shown here can be joined to the end of any pillar.
  • an actual shoe part 61 is fastened with a screw 62 to a frame part 63, which corresponds to the cylinder 40 of the joining element 20b at the end of a pillar 10b.
  • This frame cylinder 63 has inside it a corresponding cavity and an annular groove 65 for an annular spring 50.
  • the frame cylinder 63 is attached to an end plate 64, which meets the end plate 21 of the pillar.
  • Fig. 8 presents an alternative joint between reinforced concrete pillars 10a and 10b, where, before the joining, the annular spring 50 is placed in the groove 31 of rectangular cross-section of the projecting part 30.
  • the mouth of the cavity 40 has a conical shape 43 that compresses the annular spring 50 as the pillars are being joined together.
  • the annular spring 50 will expand into the groove 41 in the cavity 40 and get wedged against the conical surface 44.
  • the operation of the annular spring 50 is thus reversed.
  • the inclined surface 44 of the groove 41 in the cavity 40 must be located on the opposite side.
