Definitions

  • the present invention is comprised in the technical field of construction and, more particularly, in the sector of self-climbing perimetric protections for buildings undergoing construction, and more specifically to anchoring systems for self-climbing perimetric protection systems.
  • the elements forming said protection such as the metal support structure and the protective panels and meshes, had to be moved manually by means of a crane to the upper floors that had to be protected.
  • Self-climbing perimetric protections have been developed in recent years, which have means for being moved up and down, such that they are placed on the floors that must be perimetrically protected. Examples of such self-climbing protections can be seen in patent documents WO 2004/020766 , WO 2007/036300 and in European patent application EP 10382052.8 .
  • the object of the present invention is a perimetric protection system according to claim 1.
  • Preferred embodiments of the system are defined in the dependent claims.
  • the protection system of the present invention comprises an adjustable anchoring system for anchoring to the slabs or floors of the building. Therefore, depending on the geometry of the floor in which the protection system is used, the corresponding adjustment is made in the anchoring system such that it can move closer to or farther from the end of the floor of the building, absorbing the vertical misalignments of the building.
  • the self-climbing perimetric protection system comprises:
  • the anchoring system comprises:
  • This linear movement can cause the guiding heads to move closer to or farther from an end edge of the slab or floor of the building to be in a vertical alignment position with the guiding heads corresponding to other slabs or floors of the building and the system thus allows absorbing the vertical misalignments that may arise in the slabs or floors of the building.
  • the heads are vertically aligned, i.e., in the position suitable for the correct hoisting of the masts:
  • the displacement means can comprise a rack and at least one pinion.
  • the rack can be assembled in the anchoring parts and the pinion in the adjustable supports or vice versa.
  • the system may incorporate a first pinion (in the front part) and a second pinion (in the rear part), the pinions being arranged such that the operation of the second pinion overlaps with the operation of the first pinion.
  • the second pinion can follow the linear movement of the heads, reaching a greater distance farther away from the end edge of the slab or floor of the building.
  • the first and second pinions can be externally operable by means of a tool causing the linear sliding of the guiding heads.
  • the displacement means can also comprise guiding means which ensure contact between the rack and the first/second pinion.
  • These guiding means can comprise, for example, sliding rollers arranged in the adjustable supports and resting on the anchoring parts facilitating and guiding the sliding between both.
  • guiding means can comprise, for example, sliding rollers arranged in the adjustable supports and resting on the anchoring parts facilitating and guiding the sliding between both.
  • pairs of rollers facing one another such that part of the anchoring parts is arranged between each pair of rollers to prevent the vertical movement between both parts can be used.
  • the rollers can obviously be in the anchoring parts and rest on the adjustable supports.
  • each anchoring part has an I-beam section and a rack solidly assembled (for example by means of welding) on the upper part of each anchoring part and the adjustable support is formed by two channel irons facing one another and attached by pins (through their central branches), the adjustable support being provided with:
  • Each plurality of pairs of first rollers is separated from one another by a distance greater than the width of the rack and each plurality of pairs of second rollers is separated from one another by a distance greater than the width of the narrow part of the I-beam.
  • Each pinion is preferably attached to the channel irons by means of a pin, at one of the ends of which a hexagon head is assembled. Each pinion can thus be operated by means of a tool that can be coupled to said hexagon head.
  • the distribution of the pairs of first rollers along the adjustable support is preferably uniform.
  • the distribution of the pairs of second rollers along the adjustable support is preferably uniform.
  • the masts are each formed by preferably vertical channel irons open towards opposite lateral sides.
  • the system can thus be adapted to the changes in the geometry of the building on which it is assembled.
  • the perimetric protection system of the invention can be self-climbing, of the type described in European patent application EP 10382052.8 ; to that end, the system further comprises a self-climbing device that can be coupled to said at least two masts and to at least said guiding heads.
  • the system according to the present invention is simple, can be easily hoisted, adaptable without major changes to different work sites and made up of combinable modules making the system very versatile.
  • Figure 1 shows a side section view of a known self-climbing perimetric protection system- such as the one described in European patent application EP 10382052.8 - comprising a pair of vertical masts 1 (since it is a side view, Figure 1 only shows one of them) which are fixed to slabs or floors 5 of a building and guided by means of respective anchors 4.
  • a horizontal work or loading platform 3 can be assembled on these masts 1.
  • a vertical protective panel 2 is assembled on the masts 1.
  • the masts 1 can be, for example, standard beams having determined lengths with a continuous configuration of simple standard attachments and holes which affords extreme versatility when forming different types of structures: structures adapted to the desired floor height in each case, different sections adapted to the needs of each work site, etc.
  • the protective panel 2 can also be attached directly to the masts 1.
  • the protective panel 2 is formed with a board, it can be supported with standard horizontal wood beams 2a attached directly to the masts 1 with standard connectors.
  • the system further has support or self-climbing blocks having projections 6a emerging from the masts 1 towards the anchors 4.
  • the self-climbing system comprises a climbing head 7 connected to a guiding head 10 of the anchor 4 immediately thereunder by means of a hydraulic hoisting cylinder 9 the lower end of which is connected to the guiding head 10.
  • the mast 1 can be rigid but it can also be articulated by means of an articulation.
  • the articulation comprises an upper body attached to the upper part of the mast and a lower body attached to the lower part of the mast, which are connected to one another by means of a bolt. There are respective wedge-shaped side spaces between the upper body and the lower body which together determine the maximum angle of rotation of the articulation.
  • this articulated mast embodiment is useful when there is a variation in the geometry of the different slabs or floors of the building in the perimeter to be protected, such that there are height variations of the different slabs or floors 5.
  • the anchors 4 are placed in the same position from the end of the slabs or floors 5, so if this end varies, the masts 1, and therefore the entire assembly, have to be adapted.
  • the articulation which constitutes the attachment of two vertical parts of each mast 1, limited articulation, such as 4° of maximum rotation, for example, towards and away from the building, between those two parts of the mast 1 is allowed.
  • the present invention proposes replacing the anchors 4 with an adjustable anchoring system.
  • the adjustable anchoring system is made up of an anchoring part 20 and an adjustable support 30.
  • This anchoring part 20 comprises an I-beam section 21 which is assembled solidly by means of an anchoring cone 22 embedded in the slab or floor of the building, and forming a movement guide for the adjustable support 30.
  • a rack 23 which, as explained below, is responsible for the necessary linear movement for adjustment is fixed in the upper part of the beam 21, for example by welding.
  • the upper part of Figure 5 shows a side view and a section view of this anchoring part 20, with the I-beam 21 and the rack 23 in the upper part.
  • the adjustable support 30, comprising two channel irons 31 welded at one end to an end plate 32, which in turn has welded thereto a series of plates forming the base support for the guiding head 10. (One of the channel irons has been removed in Figure 3 for greater clarity).
  • the two channel irons 31 are open towards opposite sides and attached by pins 33, each pin being provided at its ends with a pair of first rollers 34 uniformly distributed along the channel irons although they could also be non-uniformly distributed.
  • the adjustable support 30 incorporates at least several pinions 36, 36' spaced from one another along the channel irons 31.
  • Each pinion 36, 36' is assembled integrally to the channel irons 31 by means of the corresponding pin 37.
  • FIG. 5 shows a side view of the adjustable support 30, with one of the channel irons 31, the first rollers 34, the second rollers 35 and the pinions 36.
  • Figure 6 shows a section view along line A-A of Figure 5 .
  • the adjustable support 30 can slide along the anchoring part 20: the rollers keep the adjustable support 30 attached to the anchoring part 20, and the forward and backward movement of the support on the anchoring part is by rack and pinion.
  • the pinions are operated by means of a tool (not shown) acting on the end of the pin 37 of the pinion, having a hexagon head 38 or the like, for the corresponding key and tool.
  • the upper part of Figure 7 shows the initial position of the assembly, the relative position between adjustable support 30 and anchoring part 20 being shown.
  • the linear movement of the assembly is performed by operating the pinion 36 on the rack, and thus it reaches the position shown in the intermediate part of this Figure 7 .
  • another pinion 36' is operated with the suitable tool; this pinion continues with the linear movement of the assembly until the end position shown in the lower part of Figure 7 .
  • Linear movement of the guiding heads 10, which move farther way to a greater or lesser extend (as required) from the outer edge of the slab or floor, is thus achieved such that when the masts 1 of the perimetric protection system are hoisted, the heads 10 are in the appropriate position for being coupled to the masts 1.
  • the amount of pins 33 with first rollers 34 or upper rollers, of second rollers 35 or lower rollers, and of pinions 36 depends on the adjustment length to be achieved.
  • the telescopic nature of the adjustable support 30 of the guiding head 10 allows for assembling the perimetric protection system even though the floors are not vertically aligned.
  • Figure 8a shows the self-climbing perimetric protection system of the invention assembled by means of the adjustable anchoring system for anchoring to a first slab or floor 5 of a first storey and to a second slab or floor 5 of a second storey of a building. It also shows a third slab or floor 5 and a fourth slab or floor 5a of the third and fourth storeys of the building.
  • the fourth slab or floor 5a is not vertically aligned with the other first, second and third slabs or floors 5.
