Definitions

  • This invention relates to means for the connecting or joining of beams or rods, for example of wood, that are used in the building industry when constructing horizontal or upright compositions, such as, for example, beams, roof trusses, walls, load-bearing floors and the like.
  • W02020173093A1 discloses a connection that connects up to six discontinuous square beams.
  • the connecting piece always exceeds the volume of the beams, changing the contact surface of the beams to be joined.
  • unused connecting elements must be cut off. To realize this connection, it is also necessary to know in advance the size of the cross section of the beams, the number of beams and the configuration of the joint.
  • JP2003336321 discloses a building frame connector used to join first and second sections of a column, beams, a threshold or similar. According to the description, this connector can facilitate and simplify the production process, transport and installation. With this connection, a beam must always be continuous, which can increase internal stresses and decrease the strength of the construction. To increase the strength of the connection, the insertion grooves in the beams must be narrow, which is difficult to achieve. Since a number of pins are used in this connection, it is also necessary to accurately calculate the position of the holes in the beams, which can slow down the production process.
  • FR2647861 discloses an installation system for a detachable connection of a plane of a first element with a plane of a second element.
  • the mounting system includes a first and a second component, each of them includes a support plate; means, each of which are complementary to each other, to attach it to the corresponding element, and positioning, guiding and immobilization means, which are respectively male and female and are attached to the support plate, the engagement of one of these means in regard to the other leading the support plates to move towards each other until they come into contact, thus establishing a rigid and dismountable connection between the two elements.
  • the disadvantage of this known invention is that insertion grooves for the mounting system in the beams must be narrow to realize the connection.
  • the present invention provides a solution for these disadvantages with a connection that is easy to achieve.
  • the combination of the components of the connection increases the reliability of the structure by maintaining the contact surface of the connected beams and accelerates the production process.
  • the purpose of the present invention is to provide a connection that is easy to realise, increases the reliability of the construction by retaining the contact surface of the connected beams and accelerates the production process. This objective is achieved by a connection according to the present invention.
  • connection can be carried out repeatedly by means of a limited number of components, each of which has a specific form, without having to take into account the dimensions and features of the elements to be connected.
  • connection allows up to five connections of discontinuous beams with, for example, square cross section, to be realised on site.
  • connection does not exceed the volume of the beams. As indicated above, this means that no excess parts must be removed after the connection has been realised.
  • connection can be disassembled and reassembled.
  • connection is modular/circular. More or fewer beams can be connected or disconnected to adjust the connection.
  • connection comprising an end plate, a connecting plate and a conical pin.
  • the end plate includes a slot, which connects with a close fit to a protrusion of the connecting plate.
  • the protrusion of the connecting plate comprises a cut-out.
  • This cut-out comprises a connecting element, which is configured so that the connecting plate can be connected to the end plate by means of the conical pin, characterized in that the connecting element of the connecting plate comprises an opening, which is configured to permit a lateral movement of the connecting element opposite the connecting plate when a conical pin is inserted.
  • the lateral movement of the opening of the connecting element of the connecting plate opposite the connecting plate is limited by a shape of the cut-out.
  • the connecting element of the connecting plate is resiliently suspended, preferably resiliently in the cut-out of the connecting plate.
  • the connecting element of the connecting plate is connected to the connecting plate by retaining a thin strip of material in the cutout.
  • the cut-out is funnel-shaped.
  • the connecting plate comprises several protrusions, in particular protrusions with the features as described herein.
  • the connecting plate comprises, in addition to one or more of the previous features, a slit configured to insert a second connecting plate.
  • the slit of the connecting plate can be connected with a close fit with the thickness of the second connecting plate.
  • the slit of the connecting plate has a depth up to the centre line of the connecting plate.
  • the connecting element can be placed as a separate element in the cut-out in the protrusion of the connecting plate.
  • the connecting element will be able to move transversally opposite the connecting plate by bending the resilient suspension (205) (in both directions of a z-axis of a corresponding coordinate system, which is shown in fig. 2).
  • the end plate has a square shape.
  • the end plate comprises a screw hole.
  • this invention provides a method for connecting an end plate, a connecting plate and a conical pin.
  • a protrusion of the connecting plate as described above is inserted into a slit (sometimes also referred to as slot) of the end plate and a conical pin is inserted into an opening of the connecting element of the connecting plate to create the connection by permitting a lateral movement of the connecting element opposite the connecting plate.
  • the method comprises sliding the connecting plates together using the slits provided in the connecting plates.
  • the invention relates to the method for connecting the end plate with a beam or other building element by means of a screw hole, thus using the above-mentioned method to establish a connection between at least 2 beams or other building elements.
