Definitions

  • the present invention refers to a device for the formation of chamfers on reinforced concrete pillars which has important characteristics of novelty and inventive activity.
  • the device of the present invention is intended to achieve the following objectives.
  • the device of the present invention is constituted by a triangular prismatic profile section intended to coincide with each corner edge of the shuttering of the pillar to form the chamfer, for which purpose said profile section will have two sides intended to engage with the inner faces of the pillar shuttering, and a third side intended to form the chamfer, having a long flange extending from the device, allowing it to be placed and manipulated from the outside of the pillar shuttering, and having specific inventive characteristics for obtaining a high degree of watertightness and perfect adaptation to the faces of the pillar shuttering.
  • the sealing profile section is made of a synthetic material having a certain resilience, so that the two sides intended to coincide with two adjacent faces of the pillar shuttering have a certain difference of angle with respect to said walls, according to a reduced value, so that on its placement the profile section will be arranged so that it forms very small acute angles with one and the other face of the shuttering.
  • the tensioning of the device by an extending wing of the profile section which reaches the outside of the pillar shuttering members, given the resilient characteristics of the material permits good adaptation of the sides of the profile section on the faces of the shuttering, obtaining a high degree of watertightness, which is optimised by the arrangement of respective sealing flanges extending from the corner edges of the triangular profile section.
  • the present invention provides for the arrangement of a through hole for the fixing of the device on one of the faces of the pillar shuttering, there being a slight difference in height between the axis of the hole in the device and the axis of the mounting hole, so that when a coupling bolt is inserted, at the instant of mounting it takes on a slight inclinationbecause of the above-mentioned offset, but on tightening the bolt, for example by means of the corresponding nut or a wing nut, the bolt is centred and straightened in the mounting hole, thereby resulting in a pulling effect on the extending wing of the device, which is the action which actually effects the firm and watertight application of the sides and edges of the triangular profile section to the shuttering faces.
  • Figure 1 shows diagrammatically a view in section which represents the device of the invention in the mounting state.
  • Figure 2 is a view similar to Figure 1, showing the device fully mounted.
  • Figure 3 shows a section in detail and on a larger scale of the device of the invention.
  • Figures 4 and 5 are respective perspective views of embodiments of the present invention.
  • Figures 6 and 7 are views showing a case of execution of the device according to the present invention.
  • Figure 8 shows a cross-section of a pillar provided with the device of the present invention.
  • Figure 8 shows the shuttering of a concrete pillar 1, in a customary execution of a square or rectangular pillar.
  • the shuttering is produced by means of four members 2, 3, 4 and 5 which interlock with one another, enclosing the space which will receive the concrete to form the pillar 1.
  • a device will be arranged in each of the corners as shown diagrammatically in Figures 1, 2, 6 and 7.
  • the shuttering device comprises a profile section 6, preferably hollow and made of a material having a certain resilience, such as a plastics material, which takes the form of a triangle, preferably isosceles, the shorter sides 7 and 8 of which are intended to fit on the inner faces of the shuttering, respectively 9 and 10.
  • the longer side 11 will form a chamfer on the shuttered wall, as can be seen in Figures 6, 7 and 8.
  • the profile section 6 extends in a long wing 12 which projects laterally from the shuttering wall 10, permitting its correct placing and manipulation from outside the shuttering.
  • the profile section 6 has its sides 7 and 8 forming angles and ⁇ respectively to the vertical and to the horizontal.
  • the profile section assumes the arrangement shown in Figure 1, in which it can be seen that the contact of the profile section with the shuttering faces 9 and 10 takes place at the vertices of the above-mentioned profile section and more precisely at the ends of respective flanges or profile sections 13 and 14 which are extensions of the corresponding corner edges, made of a more resilient material intimately joined to the profile section 6 and ending in a knife edge to allow good adaptation to the shuttering faces.
  • angles ⁇ and ß will have variable values determined by experience, and need to be of the minimum value that permits correct tensioning of the profile section on the shuttering faces. In practice, it has been observed that the values to be recommended are those ranging between 1 and 5 degrees, and more specifically, approximately 3 degrees.
  • the wing 12 will be subjected to a pulling action so that, by taking advantage of the resilience of the profile section, correct adaptation to the shuttering faces can be obtained, as may be observed in Figure 2.
  • a preferred form of producing said tensioning lies in making use of the mounting of the fixing bolts 15, which in the initial stage are disposed with a slight inclination owing to the offset of the corresponding hole 16 of the wing 12 with respect to the axis of the hole in which is fitted the bolt 15, which may be fixed by means of a nut or wing nut 17. That will require the hole 16, in the initial mounting position, to be at a slightly greater height than that of the axis of the hole in which is fitted the bolt 15, which, at the moment when the nut or wing nut 17 is tightened, will cause an effort to be exerted on the lower edge of the hole 16, which will be transformed into the pull on the wing 12 necessary to effect the adaptation shown in Figure 2.
  • the profile section with its wing 12, as shown in Figures 4 and 5, may be produced according to other variants such as those shown, being provided in the first case with circular holes 16, and in the second with slots 18 which will permit better adaptation to different actual structures of the shuttering.
