Definitions

  • This utility model relates to building structures, in particular, to fastening devices of the formwork, which includes devices for placing reinforcement and forming a space filled with hardening mortar, which together forms part of the building structure.
  • the closest analogue is a screed construction (RU 166729, E04G17 / 06, 04/20/2013), containing a jumper, at each end of which two plates are installed perpendicular to the axis of the jumper, one of which is an end plate and the other one is internal.
  • Each inner plate is removed from the corresponding end plate by a distance equal to the thickness of the formwork, the jumper is detachable and consists of parts.
  • the jumper contains fixing elements in the form of holes and protrusions.
  • the jumper has a groove on each end. The end plates are removable and are installed in the necessary groove located on the shank.
  • the screed construction may have an extension cord with fixing elements in the form of holes and protrusions, similar to the holes and protrusions, respectively.
  • the construction coupler may have protrusions and clips for fixing reinforcement elements. Through-holes are provided in the jumper parts and in the extension cord.
  • This screed is easy to use, however, due to the lack of a reliable lock on the fixation elements of the jumper elements containing the protrusions and holes, it has an unreliable connection, which can lead to its opening or deformation when pouring the mortar, or other external influences.
  • the technical result of the proposed utility model is the elimination of involuntary opening of the parts of the jumper of the screed when it is under pressure from the mortar, due to which a reliable holding fixation of the formwork and, if necessary, reinforcement elements is created.
  • the technical result is achieved by the fact that in the screed construction, containing two elements interconnected to form a jumper, at each end of which there is a shank with grooves for installing the plate-limiter, while the jumper elements have at least one protruding locking element and reciprocal grooves, characterized in that in the upper part of the fixing element there is a holding protrusion interacting with the grooves, and at least one cutout is made along the vertical axis.
  • the bridge elements are equipped with protrusions and reinforcement clips.
  • jumpers are installed at each end perpendicular to the axis of the plate, one of which is a latch and is located at the end, and the second, internal, is removed from it by a distance equal to the thickness of the wall panel.
  • the plate can be one - the inner one in the case when the screed is attached to the supporting wall without fixing it on the other side of the wall.
  • the presence of a retaining protrusion on the fixation elements of the jumper and extension module allows reliable fixing of the screed and, accordingly, the formwork wall, eliminating the possibility of its deformation or opening during the filling of the formwork with the building mixture and when it dries, without complicating the assembly of the structure.

  • the screed construction contains a jumper element 1, an extension 2.
  • the jumper element 1 contains a surface 12, a shank 18 and a plate-stopper 17.
  • On the surface 12 there is a fixing element 3, which is a protrusion, in the proposed embodiment, of a square shape.
  • At the base of the protrusion at the interface with the surface 12 there is an end point 13.
  • the locking element 3 is divided in the upper part by at least one cutout 6 into two parts 5, and has a retaining protrusion 7, which, to facilitate entry into the groove, includes a front inclined surface 8 near the end part 9 of part 5 and a rear surface 10 next to the extreme point 11 of the part with the front inclined surface 8.
  • Each part 5 of the locking element 3 includes an end part 9 located at the distal end from the surface 12 of the jumper element 1. Parts 5 of the locking element end at an end point 13 located adjacent to the surface 12.
  • the holding protrusion 7 of each part 5 is located near the end surface 9 and contains a part with an inclined front surface 8 and a rear surface 10.
  • a part with an inclined front surface 8 starts at the end part 9 and extends either linearly or with a slight bend to the outside, from the end part 9 to the end part 11 of part 5, while also expanding outward from an imaginary longitudinal central axis.
  • the part with the inclined front surface 8 ends at the extreme point 11, and then passes to the rear surface 10.
  • the rear surface 10 extends from the extreme point 11 at a steep angle substantially perpendicular to the longitudinal central axis to surface 12.
  • the distance from the end point 13 to the rear surface 10 may be greater than or equal to the length of the groove 4.
  • the distance between the end points 13 of the opposite petals may be less than or equal to the width of the groove 4.
  • the retaining protrusion 7 is part of the fixing element 3, which in turn is part of the building screed module.
  • the retaining protrusion 7 is part of the locking element 3, which in turn is part of the extension of the screed construction.
  • the parts 5 When the locking element 3 passes into the groove 4, the parts 5 are compressed to each other due to the notch 6. The final insertion of the locking element 3 into the groove 4 is achieved when the surface 12 of the jumper element 1 is in contact. The return of the parts 5 to their original position is due to the elastic force, that is, when the cutout is straightened 6. Due to the protrusion 7, the locking element 3 cannot be removed from the groove 4, due to the fact that the rear surface 10 is in contact with the supporting surface 12 of the element jumpers 1, which allows you to protect the modules of the screed construction from breaking and securely fix the walls of the formwork.
  • the clip 15 for creating the frame of the reinforcement is made in the form of a circle and contains a leg for mounting on the screed elements and an inlet cutout for securing the reinforcement.
  • the inlet cutout for mounting the reinforcement contains petals, spaced apart from each other by a small distance and turned inward clips and having a ribbed surface.
  • the leg for fixing on the jumper elements has a cutout corresponding to the protrusion 14 size.
  • the clips for fastening the reinforcement 15 are inserted into the protrusion 14 of the jumper element 1.
  • the clips of the reinforcement 15 should be on one side of the screed.
  • An example of the location of the clips 15 on the jumper elements is shown in the patent of the Russian Federation N ° 166729.
  • the longitudinal bars of the reinforcement are laid and fastened with the aid of the reinforcement clip 15.
  • the reinforcing cage is installed inside the formed formwork, the concrete mixture is poured with vibration compaction or bayonet. It is also possible to fix the reinforcement in the clips of the reinforcement 15, if necessary, to create the design thickness of the formwork.
  • the construction of formwork is possible from any moisture-resistant sheet, plate, masonry building materials. Formwork can be either removable or non-removable. To increase the thickness of the formwork, several extension cords can be installed, connecting them to each other until the required thickness of the concrete core is obtained.
  • the use of the described element for fixing the coupler modules will allow to exclude the possible opening or deformation of the modules (displacement fixing element relative to the entrance groove) when exposed to mechanical stresses caused by the pressure of the building mixture on the modules during pouring, and compression during setting and hardening, due to the drying of moisture from the building mixture, rigidly fastening and making the coupler modules as if in one piece, allowing protection from structural damage, loss of bearing capacity and the overall quality of the structure.
  • reinforcement clips can also contribute to the strength of the construction of the screed, due to the rigid fixation of the reinforcement, which prevents it from shifting to the side and preventing it from exerting excessive loads.
  • the fixing element is made in the form of a protrusion of a square shape, hollow inside. This has two cutouts 6 located on opposite sides of the locking protrusion and which divide the locking protrusion into two identical parts 5.
  • the protrusion can be made flat in shape, for example, as described in RF patent Ns 2584411.
  • the proposed screed fixes the formwork panels to the required distance from each other using an extension cord, allows you to type and fix various thickness of the formwork panels, as well as fix the reinforcement to the design thickness of the concrete protective layer.
