Definitions

  • the present invention relates to a support structure for formwork of walls of suspended type, which allows achieving sensible advantages with respect to what is currently known.
  • Suspended structures for wall formwork are intended to provide the means for the workers who make the formwork to carry out their work as the wall is being built, increasing its height.
  • double-type structures are used to achieve high heights of formwork handling. Said structures have, apart from their work platform or upper "console”, an important prolongation in the lower part or second "console”, allowing work in sections of the wall located below the work platform.
  • this type of structure suffers from a main problem due to its large dimensions that make it difficult to assemble the structure in the work by means of lifting cranes, especially in the initial phase of lifting the structure of the ground, where it will be mounted , until its placement for the start of the work of the same. Given the size of the structure with double console, the lifting operation is complicated by the lack of sufficient transverse stiffness of said structure, which is simply intended for its suspension coupling to the wall that will gradually be concreted.
  • the present invention is also intended for cover important aspects of security of the double consoles currently known, since in these, when reaching sensitive heights, in the order of 6 meters, the part of the structure that lies below the work platform presents itself security problems for operators who must work on it and who eventually have to move from the work platform to the lower platform mentioned, since a height of the order of 6 meters can represent dangers in case of personnel falls.
  • the present invention is based on constituting the part of the structure located below the work platform by several sections of lower height, for example, 2 meters, placing in each of them a platform of auxiliary work and constituting said sections in an articulated manner with each other, so that the rear part of each section, that is, the one adjacent to the wall under construction, which bears the auxiliary work platform, will be articulated by the two ends, upper and lower. lower, while the front part of each section will be in a first phase, disassembled by its lower part and articulated by its upper part, thus allowing the free movement and adaptation of the structure as a whole in the lifting phase from the horizontal position to move to the vertical or suspension position.
  • each section of the structure is integrally fixed, giving rigidity to the assembly and allowing 'structure with double console normal working arrangement with a working platform main and several auxiliary platforms, preferably three, one for each of the lower sections with an approximate height of 2 meters.
  • the upper part of the console which supports the shuttering panels, will be movable so that the set of the shuttering panels can move backwards, separating from the part of the wall already set, and forward, to occupy the work position.
  • These shuttering panels will also be vertically displaceable, for the purpose of adjusting their working position.
  • Figure 1 shows a schematic side elevation view of the set of elements of the support structure for formwork of walls object of the present invention, with a main platform and three sections, the two lower articulated.
  • FIG. 2 shows a front view of the elements represented in figure 1.
  • Figure 3 shows a perspective view of a structure corresponding to Figures 1 and 2, an auxiliary platform having been omitted for purposes of greater clarity.
  • Figures 4 and 5 show respective side and perspective views of an element of the lower section coupled to the work platform of the structure, with a mast for supporting the protection handrails.
  • Figure 6 shows a perspective view of part of an element such as those depicted in FIGS. Figures 5 and 6, with the mast carrying the protection handrails in folded arrangement.
  • Figure 7 is a view similar to that of figure ⁇ but with the mast carrying the protection handrails raised.
  • Figure 8 shows a detail of the interlocking means of the mast carrying the protection handrails with respect to the gusset.
  • Figure 9 shows a detail of the arrangement of means for effecting the adjustment of the shuttering panel in a vertical direction and in a horizontal direction.
  • the support structure for wall formwork comprises an upper module -1- carrier of the panels -2- for wall formwork and a work platform -3- as well as masts - 4- for protection handrails, said module being extended inferiorly in several articulated sections or modules arranged one after the other, such as those indicated with the numerals -5-, -6- and -7-, each of which will have an approximate height of 2 meters and will present an auxiliary work platform, indicated respectively with the numerals -8-, -9- and -10-.
  • the whole of the structure is intended to be suspended in the wall as its setting permits.
  • anchors will be fixed, for example -11- and -12- in the wall, allowing the suspension of the structure of said anchors.
  • the sections of structure or modules -5-, -6- and -7- have a predetermined height to avoid risks in the bricks, for example, about 2 meters, to achieve greater security within each section, since the height of each of them does not represent any special danger for the staff in the event of a fall, as occurs with the current sections that reach 6 meters.
  • the modules -6- and -7- are articulated with the corresponding front and rear platforms.
  • the structure can be lifted simply by means of a crane, said modules articulating with each other.
  • the fastening of the front elements of each module takes place after the vertical positioning of the structure, as will be explained in more detail below.
  • Each of the modules -5-, -6- and -7- is constituted in the form of a kind of cage, which in the case of the module -5- is constituted by a minimum of two end elements such as that represented in FIG. figure 1, formed by a rear arm -13- that will be adjacent to the wall, a front arm -14- as opposed to the wall and the support -15- for the main or work platform and the lower support -8- for a platform assistant.
  • the arm -14- will carry supports -16- and -17-, in variable number, for the incorporation of protection handrails.
  • the upper module -1- has a support frame -18- of the board or formwork panels -2-, said frame -18- being tiltable with respect to a lower pivot point by the action of an adjustable brace -19- incorporated between the support -15- and said frame -18-.

  • the arrangement shown in the figure achieves a correct seal to prevent leaks in the pouring of concrete.
  • the vertical displacement is achieved by the vertical spindle -33-, which allows the vertical movement of the formwork board -2- and front plate -31- to achieve the desired height position.
