Definitions

  • the present invention is framed in the technical field of construction. More specifically, a template is proposed for wood-concrete collaborative floor slab connectors that allow the correct placement of said connectors in the positions and with the inclination determined by the structural calculations.
  • the present invention presents a template for placing plug-type connectors on wood-concrete slabs.
  • the main objective is to provide a template that allows to determine precisely the correct position and inclination with which the connectors must be placed.
  • the template is placed in part or throughout the length of the beam according to the distribution of shear forces. It is a non-reusable template, which is permanently arranged between the beam to which it joins and a layer of concrete that is arranged on the template. Thanks to the fact that it is permanent, it contributes to improving the deformation and resistance of the assembly (forged wood-concrete) when it is loaded. In terms of deformation, the difference in stiffness between wood (or wood derivatives) and concrete is very high. Therefore, the template is formed of a material of intermediate stiffness between both materials that allows a more gradual transition between the deformation experienced by the ends of the floor.
  • the template can be made of wood (or products derived from wood) or any other material provided it has a stiffness greater than the beams or joists on which it sits, and less than the concrete of the compression layer itself higher.
  • the template helps to improve the resistant capacity of the assembly.
  • the plug-type connectors in mixed wood-concrete slabs work mainly on shear, tensile-compression, or a combination of these efforts, depending mainly on their angle of inclination and their arrangement.
  • the template helps to distribute the shear stress in two resistant sections, instead of one, to subject the connectors to double shear.
  • the connectors work at axial forces (tension and compression)
  • the template helps to improve the strength of the assembly by providing extra material resistant section
  • the holes in the template are arranged in the exact position where the connectors determined by the structural calculations should be placed. Also, said holes have a certain inclination with respect to the beam. This inclination determines the angle of inclination with which the connectors must be placed.
  • the template comprises one or more main bodies to cover the entire length of the beam. These main bodies are placed directly butt one after the other, or they can be gathered together by means of tongue and groove joints.
  • the holes for the connectors instead of having a diameter equal to or greater than the connector, carry a pre-drill along the entire depth of the template with a diameter smaller than that of the connector.
  • the template further comprises reusable lugs that are housed in the holes.
  • the lugs have the same inclination as the holes in which they are introduced and therefore collaborate in guiding the connectors. These lugs also allow the exact position of the head of the connectors to be determined.
  • the holes In the case that studs are used without pre-drilling, the holes have a constant diameter and larger than the diameter of the connector to be able to remove the pin once the connector is placed. In the case that pre-drilled bolts are used, the holes have two different diameters, a larger diameter where the bolt with a diameter larger than the connector is introduced and fixed so that the bolt can be removed later; and a smaller diameter smaller than the diameter of the connector that reaches the lower face of the main body of the template.
  • the template can comprise anchoring elements or pins to specify its positioning on the beam.
  • the template can comprise a plurality of notches (grooved, laminated, pointed elements or a combination thereof) on the inner face of the main body, which are nailed to the lower beam to increase the transfer of stresses .
  • the template can also comprise a rough surface (grooved, grooved) on the upper face of the main body to favor the transmission of stress with the concrete.
  • the template can comprise, on the side faces and along its entire length, a grooved tongue-and-groove type to join boards. These boards are usually arranged between two continuous slab beams providing a continuous surface necessary for concreting the compression layer.
  • the template can comprise, in addition to holes for the placement of the connectors, indications of the quality of the materials of the floor (wood and concrete), and data of the geometry and the resistant capacity of the wrought. DESCRIPTION OF THE DRAWINGS
