Definitions
- the present invention relates to a usable frame for obtaining formwork panels, as well as bolt through which the connection between the frames for obtaining the general formwork surface, specifically in the case of panels intended to be handled manually.
- the object of the invention is to obtain a rigid frame which allows easy mounting of the constituent plate of the panel itself for fast and efficient fixing for the rest of the frames or panels participating in a determined formwork.
- Manually portable formwork panels as in document DE-A-31 22 191 are made from a metal frame (1) generally braced, on which a wooden plank of reduced dimensions and weight to allow its transport and its manual handling, without the need for cranes.
- these panels also have handles that allow convenient handling for the operator, as well as support means for setting in place and support for wooden planks.
- the framework of panel presents as a fundamental characteristic the fact to incorporate a metal plate on each of its edges provided with a longitudinal alignment of orifices intended for receive the fixing locks between the frames or panels.
- the said orifices have a circular central sector and two radial projections and opposite flayed, with a width less than the diameter of the central sector and aligned longitudinally in the background of the metal plate, while each lock is materialized in a butt stock with a head at one of its ends, from a tapered terminal to the opposite end and a cross pin to near this last end, so that the general diameter of the journal is adequate to pass to through the intermediate and circular sector of one any of the orifices of the two plates to be joined, corresponding to the two adjoining frames, while the diametral spindle is dimensionally adequate for being able to pass through the extreme projections of the said orifice, in a determined position, and to constitute a retaining stop when the journal turns 90 ° by compared to the decks.
- the final stabilization of the whole, and more concretely the final tightening between the plates of the two frames, is made with the collaboration of a corner which crosses diametrically the trunnion, through a orifice operatively produced therein, this corner being at one end capped by an actuating head which facilitates the clamping action or jamming thereof, while at its opposite end it is provided with a side riveting or stamping which acts as bearing stop on the corresponding mouth of the diametral groove of the journal, preventing the total uncoupling between the pin and the corner, and by Consequently, the possible loss of one of these two elements.
- each panel incorporates a series of internal stampings which determine the shoulders on which the edges of the board forming the formwork surface proper.
- the recommended framework is configured based on a framework proper (1), rectangular in outline, stiffened at by means of a series of spacers (2) determining a reticular structure, as is the case with any what a classic formwork frame, but with the special feature that the frame itself (1) is obtained from a series of plates (3) each provided of them of a longitudinal alignment of orifices (4), in each of which an intermediate sector is established, correspondence with own reference (4), of circular configuration, and two extreme sectors (4 ') radially flailed and in opposition, preferably in the longitudinal direction, relative to the plate (3).
- Each lock is materialized in a pin (5), in diameter in agreement with that of the central sector of holes (4), through which it is likely to serve as a passage, which is facilitated by existence in said pin (5) of a frustoconical terminal (6), which caps the journal (5) at its opposite end in a head (7), while in the vicinity of the frustoconical terminal (6) there is a diametric pin (8) in turn dimensionally suitable for crossing the plates (3) through the radial and opposite extensions (4 ') of its holes (4).
- the pin (5) is also provided near its head (7) of a wide diametrical groove (9) in which is a corner (10) capped in turn and by end wider in an actuating head (11) while at its opposite end it is provided with a lateral stamping (12), especially visible in the detail of FIG. 7, which prevents its uncoupling from the journal (5).
- the whole inseparable formed by the pin (5) and the corner (10) can be coupled in the opposite holes (4) of the plates perforated (3) which belong to two formwork panels contiguous, obviously in a situation of parallelism between the transverse pin (8) of the first set and the radial extensions (4 ') of the aforesaid orifices (4).
- the journal After said coupling the journal must undergo a rotation of 90 ° so that its transverse spindle (8) is perpendicular to the extensions (4 ') of the orifices (4), in constituting a support stop on one of the plates (3), opposite to the adaptation of the wedge (10), so that when of the axial displacement of said corner (10) within the groove (9) of the trunnion, a tightening of a plate occurs compared to another, which ensures rapid union, solid and effective between the formwork panels.
- frame (1) it is provided with a series of stampings (13) along its perimeter, facing inwards and spaced from the edge internal of the frame by an extent coincident with the thickness of the wooden planks making up the formwork itself, so that these stampings act as marginal retaining stops for said boards, together with the stops established by the interior spacers (2).

Description
Claims (1)
- Cadre et verrou pour panneau de coffrage manuellement portable, qui partant d'un cadre convenablement entretoisé pour recevoir la ou les planches en bois de coffrage, ledit cadre étant muni de moyens d'accouplement à celui de panneau contigus, et d'une platine métallique périmétrale (3), pourvue d'un alignement également périmétral d'orifices (4) pour le passage des verrous d'union entre panneaux, avec la particularité spéciale que chacun des dits orifices présente un secteur intermédiaire et circulaire (4), et deux secteurs extrêmes (4') radialement prolongés et en opposition, de largeur substantiellement inférieure au diamètre du secteur intermédiaire (4), tandis que chaque verrou est matérialisé dans un tourillon (5) de diamètre en accord avec le secteur circulaire et central des orifices (4) et pourvu d'une broche transversale et diamétrale (8) à proximité d'une de ses extrémités et d'une tête (7) à son autre extrémité, broche (8) qui est dimensionnellement en accord avec les prolongements opposés (4') des orifices précités (4), de manière que dans une position angulaire pour le verrou, celui-ci soit susceptible de passer à travers les orifices (4) des deux platines (3) adjacentes, qui appartiennent à deux panneaux de coffrage contigus, caractérisés en ce que entre la tête et la broche (8) est pourvue une large rainure longitudinale et diamétrale (9) où se trouve un coin (10) de serrage pour le verrou qui, lorsque le verrou est passé à travers desdites orifices (4) et a subi un mouvement giratoire de 90°, peut être déplacé au sein de ladite rainure (9), immobilisant ainsi le verrou, ledit coin (10) incorporant à une de ses extrémité une tête (11) d'actionnement sur celui-ci, tandis que son extrémité opposée est pourvue d'un emboutissage latéral (12) qui agit en tant que butée de retenue pour ledit coin (10), qui empêche son désaccouplement par rapport au tourillon (5).
