Definitions

  • the present invention relates to an element for assembling form-work, of the type constituted by a plurality of planks of wood positioned alongside each other.
  • Form-work of the aforementioned type is well known; since these service structures are intended to confer the desired shape on the cast concrete and to support it until it has reached a sufficient consistency, it is important that the form-work should constitute a substantially rigid, non-deformable container with an accurate geometry.
  • planks which constitute the form-work are usually aligned side by side and joined together at suitable intervals by wooden battens, nailed to the planks perpendicular to the alignment thereof.
  • the battens must therefore be straight and sufficiently strong to give a substantially flat surface on which to nail the planks of the form-work.
  • the object of the present invention is to provide an element for the assembly of form-work which is able to overcome the aforesaid disadvantages; the object is, in particular, to provide an element able to ensure over time the required characteristics of straightness and flatness, which enable carpenters to assemble form-work of optimum characteristics both rapidly and accurately.
  • Another object of the present invention is to provide an element which can be fitted to auxiliary elements which enable it to be used, in particular but not exclusively, to construct form-work of horizontal slabs for ceilings or inclined ones, such as are used for stairs.
  • a further object of the invention is to provide an element which can be fitted in a stable manner to auxiliary elements for supporting blocks forming a support structure.
  • planks of wood arranged with their longitudinal edges adjacent, one above the other are indicated 10, and are fixed to and supported by a composite element according to the invention, generally indicated 20.
  • the composite element 20 includes a rigid rectilinear core 21, preferably constituted by a metal box section with a quadrilateral cross section, with a pair of battens 24 and 25 fixed to the opposing surfaces 22 and 23 thereof, constituted by the long sides of the rectangle, the battens 24 and 25 being made of wood or other material of a consistency enabling the planks constituting the form-work to be nailed together.
  • the battens 24, 25 are fixed to the central section 21 by self-tapping screws 27, the free ends 27a of which protrude within the central box section element 21.
  • the screws 27 are preferably arranged in pairs at suitable intervals along the length of the element 20, so as to hold the battens tight against the straight box section element 21.
  • the battens 24, 25 thus have flat outer surfaces 24a, 25a respectively, one of which acts as a support and fixing surface for the planks 10 to be nailed by nails 26.
  • Pairs of aligned apertures 29 are formed at regular intervals along the short sides 28 of the box section element 21, which can be used advantageously for fixing auxiliary elements to the element 20, as described hereinafter.
  • an auxiliary element such as an external bracket, with a substantially C-shaped section, is indicated 30.
  • the bracket 30 has a central portion 31 and two lateral arms 31 perpendicular to the central portion 31, the lateral arms 32 extend so as substantially to cover the short sides 28 of the section 21, or at least the apertures 29 formed therein.
  • Apertures 33 are formed near the end, or free portion of the arms 32 and aligned with the apertures 29 in the section 21 in order to enable a transverse connection pin 34, in this case a bolt, to be passed through.
  • a transverse projecting beam-shaped portion 36 Rigidly fixed to the bracket portion 30, preferably by welding 35 to one of the two lateral arms 32 thereof, is a transverse projecting beam-shaped portion 36 that can be used advantageously to support one or more planks (not illustrated) constituting a support structure alongside the planks 10 of the form-work.
  • the opposite end of the beam portion 36 forms, advantageously, an upturned cup shape 37 into which the top end of a support column 38 can be fitted, in order to give the support structure greater stability (not illustrated).
  • the upturned cup-shape element 37 could act as housing for an upper vertical rod in which seats, consisting of vertical slots, are formed for housing and supporting one or more vertically arranged planks delimiting the scaffolding laterally and thus constituting a barrier for the safety of people climbing onto the scaffolding.
  • the lateral apertures 29 could also be used to anchor the form-work by means of a tie (a cable, for example) fixed to a post embedded in the ground.
  • a tie a cable, for example
  • the element 20 is arranged horizontally for connecting and supporting a series of horizontal planks 10 for the casting of a horizontal concrete slab 39.
  • the auxiliary element fitted to the box section element 21 is constituted by a junction element 40, which is fixed pivotally to the box section element 21 by means of a pin or bolt 34 and is operable for connection to a support beam 41 arranged perpendicular to the surface of the slab under construction.
  • the auxiliary element 40 of Figure 3 has a pair of lateral arms 42 in which appropriate apertures 43 are formed which can be aligned with the apertures 29 of the box section element 21.
  • the composite element 20 is strong enough to support the weight of a concrete slab, provided a sufficient number of beams 41 are in position.
  • the angular orientation of the auxiliary bracket element 40 can be adjusted with respect to the composite element 20, for the formation, for example, of an inclined slab forming part of a staircase (not shown).
  • connection means preferably constituted by a section 44 with a cross-section matching the opening at either end of the quadrilateral box section elements 21, is inserted into the open ends of the quadrilateral sections; each section 44 is partially inserted into an end of each of two adjacent section elements.
  • a substantially continuous support and connection element can thus be assembled from a succession of composite elements 20 extending for the length of the form-work.
  • the end portions 27a of the self-tapping screws 27 which project into the box section elements 21 can usefully be used as a stop element for determining the longitudinal position of the junction sections 44 relative to the elements 21 into which they are inserted.
  • the screws 27 closest to the ends of the element 20 are spaced from the said ends by just over half the length of the sections 44.
  • the battens 24 and 25 can be fixed by gluing to the surfaces 22 and 23 of the box section element 21; in this case, the screws 27 are no longer necessary.
  • the junction sections 44 could have one or more central holes 45 into which would be inserted corresponding pins 46 so as to project from at least one of the two surfaces of the section.
  • the protruding portion of the pins 46 would act as a stop element, fulfilling the same function as the end portions of the screws 27a of the screws 27 as stated earlier; in the embodiment of Figure 5, the pins 46 ensure that one half of each junction section 44 is inserted into a quadrilateral section, and the other half into the adjacent section.
  • Junction elements which are around 20 cm long ensure that the elements 20 are stable and well aligned.
