DESCRIPTION OF A PREFERRED EMBODIMENT

[0036] In light of the aforementioned figures, and in accordance with the adopted numbering, one may observe therein an example of a preferred embodiment of the invention, which comprises the parts and elements indicated and described in detail below.

[0037] In the embodiment, an anchoring head is shown, indicated generally with the reference (1), for installation on formwork struts (2), envisioned to support two adjacent beams (3) axially aligned with each other at an angle of inclination with respect to a horizontal plane, comprising a support, a region defined by an internally hollow elongated profile (4) configured to be coupled to a strut (2), which extends at the upper and lower ends with respect to the support.

[0038] The support comprises visual indicating means, described in greater detail below, which are configured to indicate the angular position of each one of the beams to be supported, the indicating means being associated with the positioning shaft (5) of the beam to be supported by a cam arrangement. This cam arrangement is provided with a cam member coupled to the positioning shaft (5), such that the position of the cam is directly related to the height at which the positioning shaft (5) is located.

[0039] The support has two casings (6) spaced apart and joined together by at least one central platen (7) wherein an elongated profile (3) is arranged, the height adjusting means and the locking means being mounted on each one of the casings (6). The casings (6) are made of any suitable material, such as metal.

[0040] It must be noted that relative terms with orientations, such as “upper”, “lower”, “above” and “below” should be considered in a condition of the anchoring head mounted on a strut vertically arranged with respect to a support surface or ground.

[0041] Going into greater detail regarding the cam arrangement, it comprises the cam member (8) mounted on each one of the ends of the positioning shaft (5), the cam member (8) (with an outer contour in the form of a “snail” such that it has a variable diameter) being provided with a cam surface configured to come into contact with a static region located in the support. As can be seen, this static region is defined by a pair of pins (9) separated from each other, which are in contact with the surface of the cam member at all times.

[0042] It should be mentioned that the two static regions arranged on the same side of the support (6) are offset a gap (d) (see FIG. 4) from each other with respect to a horizontal plane, such that each one of the static regions is located at a different height.

[0043] Now, with respect to the visual indicating means present in the cam arrangement, they comprise a plurality of marks (10) that indicate the slope of the beam (3) to be supported with respect to a horizontal plane, and a reference mark (11) situated in the support, more specifically between the two pins (9). As can be seen, these marks (10) are distributed along the periphery of the surface of the cam member (8) and indicate a percentage of inclination ranging from 0% to 16%.

[0044] With respect to the height adjusting means, they comprise bolts (12) that are vertically arranged and pass through holes (60) made in the casings (6). These bolts (12) are each provided with a pair of threaded portions (120) located at the upper and lower ends. In FIGS. 2 and 4, it can be seen how the bolt has a central widened region (121) having a through hole (122) where the positioning shaft is coupled. Each one of the casings (6) that make up the support includes mounting holes (13) through which the positioning shaft (5) can slide to place it at the desired height. The length (or height) of the mounting holes (13) determines the total path that the positioning shaft (5) can cover to place the beams (3).

[0045] Referring now to the locking means, they consist of a combination of hexagonal clamping nuts (14) located in the top portion, that is to say, threaded in the threaded top portion (120) and clamping nuts with a knurled outer surface (15) coupled to the threaded portions (120) of the lower portion of the bolt (12). As can be seen more clearly in FIG. 2, the hexagonal clamping nuts (14) located on the top portion of each one of the casings (6) include a washer (20), such that it ensures the correct positioning of the nuts on the surface of the casing (6).

[0046] Additionally, to ensure a contact between the top portion of the formwork strut (2) and a formwork board (not depicted), the elongated profile (4) that forms part of the anchoring head (1) includes in the top portion thereof a tiltable support surface, which is made up of a platen (16) that is rotatably hinged by means of a rotation shaft (17) coupled to the top portion of said profile (4).

[0047] The profile (4) includes a fastening system at the lower portion thereof, indicated generally with the reference (18) comprising a region (180) with a substantially rectangular shape, which is provided with a plurality of through holes (181) configured for the insertion of screw elements (not shown) and a plurality of projections (182) with a substantially spherical shape that protrude perpendicularly with respect to the longitudinal axis of the elongated profile (4), which are provided for the arrangement of diagonally arranged bars or profiles that provide greater stabilisation. The plurality of projections (182) adopts a general cross-shaped radial arrangement and are configured to fit in grooves present in the diagonal profiles. In this specification, the coupling system between the fastening system (18) and the diagonal profiles will not be entered into greater detail as it is not the subject of the present invention.

[0048] Next, the operation of the anchoring head (1) described above is described once it is placed on a formwork strut (2).

[0049] First, an operator releases the positioning shafts (5) by unscrewing the nuts (14) and (15) that support the positioning shafts (5). It should be mentioned that the stresses exerted by the weight of the beams to be supported (3) are mainly supported by the hexagonal nuts (16) located in the top portion of the anchoring head (1). Next, the operator raises or lowers one or both positioning shafts, while performing a rotation thereof, in such a way that it matches the mark (10) that indicates the desired slope to obtain with the reference mark (11) present in the casing (6). Subsequently, once the operator has the desired height of the positioning shaft that corresponds to the slope, he first screws the lower nuts and then the upper nuts to block the movement of the positioning shaft (5) during use thereof.

[0050] FIG. 8 shows an arrangement of two anchoring heads (1) supporting three beams (3), which are axially aligned with each other and arranged in a horizontal plan situated e (see longitudinal axis (E)), so that the cam member in each one of the anchoring elements (1) is arranged such that the marking visually indicates a 0% slope (see the enlarged details relating to the cam member of each one of the anchoring heads).

[0051] It can be seen from FIG. 9 a second arrangement having two anchoring heads (1) supporting three beams (3), two of the beams being aligned with each other and inclined with respect to a third beam (located to the right of the drawing) which is arranged in a horizontal plane. In this case, the two beams (3) are inclined by 5 degrees with respect to the horizontal beam, as indicated in the cam members of the anchoring head (1) located to the left of the drawing (see the enlarged details relating to the cam member), that is, the mark (10) indicating 5% is aligned with the reference mark (11).

[0052] FIG. 10 shows a third arrangement of two anchoring heads (1) supporting three beams (3), two of the beams being aligned with each other and inclined with respect to a third beam (located to the right of the drawing) which is arranged in a horizontal plane. In this case, the two beams are inclined by 16 degrees with respect to the horizontal beam, as indicated in the cam members of the anchoring head (1) located to the left of the drawing (see the enlarged details relating to the cam member), that is, the mark (10) indicating 16% is aligned with the reference mark (11).

[0053] The details, shapes, dimensions and other accessory elements, used to manufacture the anchoring head of the invention, may be suitably substituted for others which do not depart from the scope defined by the claims which are included below.
