Definitions

  • This invention involves a reinforcement tie for structural use, similar to those which are embedded in prefabricated wall bed joints that already have a pre-designated function related to the mechanical performance of the wall in which they are installed.
  • Prefabricated reinforcement ties that are used for embedding in masonry wall bed joints (also known as “bed joint reinforcement ties”) and which are intended to improve the mechanical performance of walls, consist of two longitudinal steel bars or plates connected at given distances by other transverse bars or plates, or by a continuous plate forming a triangular lattice.
  • joint reinforcement ties currently on the market come in various geometrical configurations, but their geometry always remains constant throughout the piece, keeping the same position, even at the ends.
  • the applicant's GEOFOR@ standard reinforcement tie belongs to the triangular lattice group.
  • the unique characteristic of this arrangement is that the reinforcement tie cannot be deformed in its plane. This provides a crucial advantage for the component's mechanical performance by making it resistant to perpendicular forces from the wall along its plane, regardless of the contribution of the mortar in which it is embedded.
  • the overlapping is installed along the same plane, connected to the end of a contiguous component.
  • the goal of this invention is to create a reinforcement tie for structural use in embedding in masonry wall bed joints that will be able to overcome the drawbacks of the proposals of the prior art, and which will make it possible to transmit forces properly between each reinforcement tie and its contiguous reinforcement tie-- an aspect that is crucial for assigning structural functions to reinforcement ties.
  • the invention involves a reinforcement tie for structural use comprising two longitudinal bars or plates connected by internal bars or plates, ending in a female end and a male end that is narrower than the female one.
  • a reinforcement tie for structural use comprising two longitudinal bars or plates connected by internal bars or plates, ending in a female end and a male end that is narrower than the female one.
  • the cross section of the corresponding internal bars or plates is, totally or partially, less than the cross section of the other internal bars or plates, or in at least one of the male and female ends, the corresponding internal bars or plates have an area where the bar or plate changes direction, with this area forming an entrance slot.
  • Another advantage of the invention is that it makes it possible to avoid manipulating the parts during construction, since the geometry of the internal bars is modified during the manufacturing process.
  • Figures 1 - 5B show configurations with bed reinforcement tie from the prior art with triangle lattice.
  • Figure 1 shows a standard, triangle lattice shaped bed reinforcement tie. Here a triangular area can be seen, the plane of which cannot be deformed. Force is transmitted by the reinforcement tie itself (indicated by the letter 'a'). It has non-triangulated anchor areas and the forces are transmitted by adherence to the mortar (indicated by the letter 'b'). It also shows a series of diagonal segments at the end, which are inert for mechanical performance (indicated by the letter 'c'), and cut sections of the reinforcement tie (indicated by the letter 'd') which are unprotected against corrosion.
  • Figure 2 shows a plan view of two overlapped triangle lattice bed reinforcement ties designed with the prior art, together with their overlap lengths.
  • the overlapping is installed along the same plane, connected to the end of a contiguous component.
  • the maximum possible overlap length without cutting the reinforcement ties is marked as 'L'.
  • Figure 3 shows a plan view of two overlapped bed reinforcement ties designed with the prior art, with their overlap length (L) increased. This overlap length is necessary for transmitting forces; therefore, shears are used on site to make at least one diagonal cut at each end of the piece (indicated as 'e' in the figure).
  • Figure 4A shows a plan view of a bed reinforcement tie from the prior art on masonry components, indicating the distance (D) of the reinforcement tie from the lateral side of the wall formed by the components.
  • This reinforcement tie is made of protected steel, so a minimum lateral covering of 15 mm is sufficient.
  • the width of the masonry piece is marked as 'A' and the nominal width of the reinforcement tie is marked as 'Z'.
  • Figure 4B shows a plan view of two bed reinforcement ties from the prior art, overlapping masonry components, indicating the distance (D) of the reinforcement ties from the lateral side of the wall in the overlap area.
  • These reinforcement ties are made of protected steel, but their cut sections are made of unprotected steel. A minimum lateral covering of 30 mm is therefore needed.
  • the width of the masonry piece is marked as 'A'
  • the nominal width of the reinforcement tie is marked as 'Z'
  • the unprotected cut section is marked as 'C'. It can also be noted in the figure that in order to adhere to the minimum coverings specified by standards as a protection requirement, the lateral edges of bed reinforcement ties in overlapping areas must have narrower reinforcement tie than what would be viable in a centre area.
  • Figure 5A shows a bed reinforcement tie from the prior art in a hollow bed reinforcement tie assembly, indicating the distance from the reinforcement tie to the lateral edge and the lateral bands of mortar, (m).
  • the mortar in the reinforcement ties is installed in two bands (m) located alongside the wall faces, and the centre area is left hollow, as can be seen in the figure.
  • the width of the masonry piece is marked as 'A', and the reinforcement tie width compatible with the piece in order for it to enter into the mortar band (m) is marked as 'Z'.
  • Hollow reinforced bed assemblies must have a minimum width for the reinforcement tie to be installed in the outer band of mortar (m).
  • Figure 5B shows how this situation is incompatible with the minimum coverage reinforcement ties must have in their overlap areas.
  • the required protection width is marked as 'A', which is incompatible with the width of the piece, because it does not fit in the band of mortar (m).
  • Figures 6 - 10 show reinforcement tie configuration 1 of the invention.
  • Figure 6 shows a plan view of reinforcement tie 1. It can be seen that reinforcement tie 1 comprises two longitudinal bars or plates 2 connected by internal bars or plates 3, ending in a female end 4 and a male end 5, which is narrower than the female end 4.
  • Figures 8 - 10 show that the cross section of internal corresponding bars or plates 3 is less in its ends in a specific area (i.e., partially lower) than the cross section of the other internal bars or plates 3. This reduction in height can be achieved by, for example, local flattening at the overlap points (area 6).
  • This configuration would work either at just one end of the reinforcement tie 1, which could be both the female end 4 and the male end 5, or it could be done at both ends at the same time.
  • Figure 7 shows a plan view of the end of a reinforcement tie 1 installed for structural use of the invention, with the end of one of the contiguous reinforcement ties 1 level and superimposed.
  • Figure 8 shows a detailed perspective of the diagonal bars or wires 3 with the modified geometry. It shows how the wire 3 cross section is changed in the overlap area 6 in order to reduce the height.
  • the section transitions from circular sections to rectangular ones.
  • Figure 9 shows a detailed perspective of two reinforcement ties 1, contiguous and overlapping by superimposition, holding one of the longitudinal wires or bars 2 of one of the recesses of the other reinforcement ties 1. This recess makes it possible to position the reinforcement tie 1 correctly along the width of the wall.
  • Figure 10 shows a section schematic of the end of a reinforcement tie 1 for structural use of the invention from Figure 7 , installed in the wall reinforcement tie located inside the wall 9. It shows how the height of the diagonal or transversal bar 3 is reduced if necessary, in order to make it possible to superimpose the reinforcement tie 1 contiguously without prejudicing the required covering.
  • Figures 11 - 14 show another reinforcement tie configuration 1 of the invention.
  • the guide for the bars or wires that make up the diagonal ends changes the plane locally, retaining the same form and dimensions in its cross sections.
  • the plane of the wires is changed during the manufacturing process using whichever mechanical procedure is most suitable. This basically consists of modifying the diagonal wire's guide, forming a slot 7 into which the contiguous piece will be inserted.
  • This configuration not only allows the reinforcement ties 1 to overlap over each other, but it also ensures that they are correctly located inside the wall 9, because their location is created when the diagonal guide is changed.
  • Figure 12 is a detailed perspective of the reinforcement tie 1 with its diagonal modified in the overlap area, forming a slot 7 and retaining its circular cross section and size.1
  • Figure 13 shows a detailed perspective of two contiguous reinforcement ties overlapping by superimposition, holding one of the longitudinal wires 2 of one of them in the slot 7 created in the other.
  • the slot 7 makes it possible to position the reinforcement tie 1 correctly along the width of the wall 9.
  • Figure 14 is a section schematic of the wall reinforcement tie 1 with the diagonal guide modified and installed inside the wall 9.
  • the slot 7 created by the wire 3 can be seen, making it possible to house the reinforcement tie 1 contiguously without decreasing the required covering.
  • Figure 15 shows another configuration of the reinforcement tie 1 from the invention. It consists of using a cross section of internal bars or plates 3 from at least one of the male 5 and female 4 ends that is less than the section of the other internal bars or plates 3.
  • the diameter of the internal bars or wires 3 in the corresponding end(s) must be smaller than that of the other internal bars or wires 3.
  • the invention's scope may include any type of prefabricated wall reinforcement ties (wire or plate reinforcement ties) with any type of geometry (ladder joint reinforcement ties or triangle lattice reinforcement ties with internal bars or plates arranged as diagonals), and with any wire (or plate) width or diameter.
  • the internal bars or plates 3 prefferably be arranged as a continuous bar or plate, forming a triangle lattice inside the male end 5 and as another continuous bar or plate forming a lattice in the rest of the interior of the reinforcement tie 1.
  • the internal bars or plates 3 may be arranged in parallel in transversal position (ladder joint reinforcement tie).
  • each one of the male end 5 and the female end 4 comprises two internal bars or plates 3.
  • the longitudinal bars or plates 2 of the female end 4 are folded inward at their free end 8.
