Definitions
- the present invention relates to a system for the formwork of perimeter trenches of concrete structures, that is, for the formwork of the so-called "edge beams" that make up the aforementioned perimeter strips.
- the inventor has carried out tests and trials aimed at achieving a new system allowing the formwork for perimeter strips to be carried out quickly, with a reduced contribution of labor and with high safety features, firstly so that the personnel can perform all the work from inside a floor slab, that is, away from the free edge of the floor and without having to approach it excessively for any of the phases of work.
- a new formwork system for strips perimeter that allows to achieve the aforementioned objectives allowing quick and safe assembly and disassembly of the formwork.
- the system consists of a set of elements that are integrated with each other in the formwork assembly and that are then easily recovered and transported equally safely and compactly, comprising: a) a set of struts preferably arranged in 'alignments' according to parallel planes, an alignment of struts being found on the edge of the support floor formwork; b) a minimum of two belt beams intended for parallel mounting on two strut alignments; c) bracing bars transversely coupled between the belt beams; d) crossbars incorporated in transverse arrangement on the belt beams, intended to receive the horizontal formwork panels and each of them, at the outer end, an outer jaw intended to support vertical formwork panels and in the inner part a jaw.
- the jaws are easily operated by threaded spindles and popcorn, from inside the floor of the floor, which greatly facilitates assembly and disassembly with remarkable safety for personnel.
- Figure 1 shows a perspective view of the formwork system as a whole.
- Figure 2 shows a phase of the assembly of the formwork system with support struts of a belt carrier beam and another belt carrier beam suspended by bracing bars.
- Figure 3 shows another phase of the assembly in which, by means of other struts and from the inside, the second belt carrier beam is lifted to its working position.
- Figure 4 shows the arrangement of struts, fastening tape and belt beams.
- Figure -5 shows the complete set equipped with all the crossbars and jaws as well as a guardrail, corresponding to Figure 1 with the representation of the upper floor slab and part of the perimeter fence.
- Figure 6 shows a belt carrier beam
- Figure 7 shows a bracing crossbar.
- Figure 8 shows a crossbar intended to support the outer and inner jaws and the horizontal formwork panels.
- Figure 9 shows a side elevation view of an outer jaw.
- Figure 10 shows a perspective view of the inner jaw.
- Figure 11 shows a perspective view of the coupling of a bracing bar with a belt carrier beam.
- the formwork system for perimeter strips object of the present invention comprises a set of struts integrated, at least, by two alignments of struts, one of them outer, formed by several struts -1-, -1'-, -1 "-... placed immediately to the edge -2- of the floor slab on which the system will be mounted.
- a second alignment of struts is arranged parallel to the first, on the floor slab -4-, in an area away from the outer edge -2-, being one of the struts, for example, the end struts -3- and -3 "-, supported on tripods.
- each alignment may be variable depending on the dimensions of the formwork and a higher number of strut alignment could also be provided.
- Each of the strut alignments is intended to receive belt beams, the belt beams -5- and -6- that have been depicted in greater detail in Figure 6 being represented in the drawing.
- the crossbars -7-, -7'-, -7 "-... will be located to support the horizontal formwork panels and both external and internal jaws.
- the external jaws that is, those closest of the edge -2- of the slab, they have been indicated with the numerals -8-, -8 1 -, -8 "-... and the inner jaws, with the numerals -9-, -9'-, -9" -
- the assembly process of the set of system elements will be observed in Figures 2 to 5.
- Figure 2 shows two first struts -3-, -3 "- of alignment farthest from the edge -2- of the floor slab -4-, observing that the rear belt carrier beam -5 has already been mounted above said struts - and, suspended from the transverse bracing bars -10- and -10'-, the second belt carrier or front belt carrier beam -6- Said front belt carrier beam -6- is suspended from the bracing bars -10- and -10 '- and these in turn are suspended in the same way articulated and detachable from the carrier beam -5-, by means of suspension elements that will be explained.
- Figure 3 shows the arrangement of two struts -1-, -1'- of the front alignment, which, when tilted from the inside for greater safety, allow the lifting of the structure formed by the belt beams -5- and -6- and the bracing bars -10- and -10'- to their working position.
- the bracing bars are articulated along an axis parallel to the longitudinal axis of the belts, but with respect to the vertical axis they constitute a recess, so that once the structure is assembled, the rectangle consisting of two belts and two bracing bars It is rigid or undeformable.
- a belt or similar element 11 will be coupled between the rear belt carrier beam 5 and the floor slab -4 -, - to give greater stability to the assembly, placing the struts -1- and -1 "- in immediate position to the front edge -2- of the slab and placing the rest of struts of the front and rear alignments which in this case consist of the struts -I 1 - and -3 1 -.
- Another of the additional elements of the system consists of the upper protection railing, indicated as a whole with the numeral -13-, whose vertical uprights -14-, -14'-, -14 "- are mounted in support housings of the respective front jaws.
- Figure 6 shows a belt carrier beam -5- in which the arrangement of pairs of upper rings -15-, -15'-, -15 "-... intended to receive the crossbars -7-, -7'-, -7 "- and hooks -16- and -16'- for the bracing bars -10- and -10'-.
- said hooks can be made in any preferred way, in the case shown their constitution has been shown based on two pairs of bridge-shaped bridges that determine a space for the coupling of the ends of the bracing bar terminals that can be seen in figure 7, observing two elements -17- and -17'- laterally protruding, intended for coupling in said hooks, as can be seen in the detail of figure 11 , in which the placement of the transverse element -17- of the bar -10- between the adjacent rings -18- and -18'- of the pair of rings -16- of the belt carrier beam is observed.
- a crossbar -7- is shown, observing in it the arrangement of a hook -18- in the back, directed downwards and intended to embrace the belt carrier beam -5-, leading in the front part -19- coupling of tubular type.
- FIG 9 a front jaw -8- is observed in greater detail, showing the arrangement of the threaded spindle -20- and the upper actuating knob -21-, as well as the lower hook -22- and the body -23- with Your support card.
- the placement and handling of the jaw is very simple and safe because the operator is at all times inside the floor slab, well separated from the edge.
- FIG 10 a rear jaw -9- is shown in which "the body -24- is appreciated to be engaged in the corresponding crossbar and to accommodate a wooden strip or block -27-, figure 1, with the object of power fix, by means of nails or screws, the panels that will constitute the lateral formwork of the beam, also having a threaded spindle -25- with its actuating lever -26-
- the coupling and actuation of the inner jaw is very similar to that of the front jaw that has been described
- the present invention mainly refers to the perimeter "beams” or “hanging” formwork formwork, it would also be applicable to the formwork of such non-perimetral beams, that is to say interiors, using internal jaws on both sides of the beam. to form.
