Support head, ceiling support, and ceiling formwork having such a ceiling support

Abstract

A support head and a ceiling support. The support head in particular has a plate-shaped design and has multiple guide tabs. The guide tabs are arranged or provided in such a way that a formwork element is secured on the support head so as to prevent shifting, preferably at various positions. The support head has widely opened first guide tabs that are situated opposite from less widely opened guide tabs. This asymmetry of the support head allows the support head to be situated close to a wall corner, while at the same time the formwork element can be easily fastened.

DETAILED DESCRIPTION OF THE INVENTION

(18) FIG. 1 shows a ceiling formwork 10 comprising four formwork elements 12 and a ceiling support 14. The ceiling support 14 has a support head 16 that is connected to a formwork support 18. In the present example, the formwork elements 12 each rest at their corners on the support head 16.

(19) FIG. 2 shows the support head 16 by itself. The support head 16 is formed from sheet steel that is partially cut to shape and partially bent. The support head 16 has a support plate 20 whose top side forms a support plane 22 in the mounted state of the support head 16. First guide tabs 26a-d are provided on the support plate 20 on a first side 24. Second guide tabs 30a-d are provided on a second side 28 situated opposite from the first side 24. The first guide tabs 26a-d are spread apart farther than are the second guide tabs 30a-d. Fastening a formwork element 12 (see FIG. 1) from a great distance is thus much easier on the first side 24 than on the second side 28.

(20) It is apparent from FIG. 2 that the guide tabs 26a-d, 30a-d in each case have protrusions 31a-h to allow the support head 16 to engage behind the formwork elements 12.

(21) FIG. 3 shows the support head 16 according to FIG. 2 in a top view. It is apparent from FIG. 3 that the first guide tabs 26a-d form a first guide tab pair 32 and a second guide tab pair 34. The second guide tabs 30a-d form a third guide tab pair 36 and a fourth guide tab pair 38. The support head 16 has spacer tabs 40a-d between the first guide tabs 26a-d and the second guide tabs 30a-d. The spacer tabs 40a, 40b form a first spacer tab pair 42, and the spacer tabs 40c, 40d form a second spacer tab pair 44.

(22) The first guide tab pair 32 together with the third guide tab pair 36 and the first spacer tab pair 42 defines a first channel guide 46. The second guide tab pair 34 together with the fourth guide tab pair 38 and the second spacer tab pair 44 defines a second channel guide 48. In addition, the space between the first guide tab pair 32 and the first spacer tab pair 42, as well as the space between the second guide tab pair 34 and the second spacer tab pair 44, define a third channel guide 50. Lastly, the space between the third guide tab pair 36 and the first spacer tab pair 42, as well as the space between the fourth guide tab pair 38 and the second spacer tab pair 44, define a fourth channel guide 52. The channel guides 46, 48, 50, 52 form options for frame sections to accommodate formwork elements 12 (see FIG. 1). The channel guides 46, 48, 50, 52 preferably delimit a square. More preferably, the channel guides 46, 48, 50, 52 are provided centrally with respect to a connecting area 54 of the support head 16. The support head 16 may thus be situated on formwork elements 12, in the position shown in FIG. 1, or rotated by 90 in the support plane 22.

(23) A first beam insertion area 56 with lateral guides 58a, 58b in the form of tabs is provided in the support plate 20, between the first guide tab pair 32 and the second guide tab pair 34. In addition, a second beam insertion area 60 with lateral guides 62a, 62b in the form of tabs is provided in the support plate 20, between the third guide tab pair 36 and the fourth guide tab pair 38. Beams 90 are fastenable in the beam insertion areas 56, 60 in a tilt-proof manner (see FIGS. 13 through 15).

(24) FIG. 4 shows a view of a formwork element 12. It is apparent from FIG. 4 that the formwork element 12 has connecting protrusions, of which only the connecting protrusions 64a-h are provided with reference numerals for reasons of clarity. The connecting protrusions 64a-h are used for positioning support heads 16 (see FIG. 1) or support heads 16a-f (see FIG. 5) on the formwork element 12 with a precise fit.

(25) The formwork element 12 has outer abutment faces 68a-d in the plane of a formwork shell 66, which in the mounted state abut on a wall (not shown), or in the case of multiple identical formwork elements 12, abut against one another in flush alignment.

(26) FIG. 5 shows support heads 16a-f on the formwork element 12 according to FIG. 4. The support head 16a is maximally covered by the formwork element 12. The abutment faces 68a, 68b not visible in FIG. 5 (see FIG. 4) are in flush alignment with the farthest protruding portions of the support head 16a. In this way, the support head 16a together with the formwork element 12 may be situated flush in a wall corner (not shown).

(27) In contrast, the formwork element 12 is only partially supported on the support heads 16c, 16d, 16f, so that further formwork elements 12 (see FIG. 1; not shown in FIG. 5) may be attached to the support heads 16c, 16d, 16f.

(28) The support heads 16b, 16e are used to centrally support the formwork element 12 for very heavy roofs to be concreted. The support head 16b does not protrude beyond the formwork element 12, so that the formwork element 12 may be positioned directly on a wall or in parallel to a wall. A further formwork element 12 (not shown in FIG. 5) may be attached to the support head 16e.

(29) FIG. 6 shows an enlarged detail A from FIG. 5. It is apparent from FIG. 6 that the formwork element 12 is positioned in the first channel guide 46 and in the fourth channel guide 52. Connecting protrusions 64b, 64c ensure exact placement of the formwork element 12 on the support head 16a. The connecting protrusions 64a-c are preferably part of an angled metal sheet of the formwork element 12.

(30) FIG. 7 shows an enlarged detail B from FIG. 5. It is apparent from FIG. 7 that the formwork element 12 is held in the first channel guide 46 on the support head 16b. The formwork element 12 is positioned by connecting protrusions 64d, 64e that rest against the spacer tab 40b. The formwork element 12 is thus fixed relative to the support head 16b, in the direction of the longitudinal axis 70 of the formwork element 12. The connecting protrusions 64d, 64e are preferably part of a sheet metal strip of the formwork element 12.

(31) FIG. 8 shows an enlarged detail C from FIG. 5. It is apparent from FIG. 8 that the formwork element 12 is positioned in the first channel guide 46 and in the fourth channel guide 52. The connecting protrusion 64g is engaged from behind by the second guide tab 30b, so that the support head 16c is securely fastened to the formwork element 12 with protection against shifting.

(32) FIG. 9 shows a perspective bottom view of the support head 16. The support head 16 includes the connecting area 54. The support head 16 has a tube 72 in the connecting area 54.

(33) FIG. 10 shows the ceiling support 14 according to FIG. 1 during mounting thereof. The ceiling support 14 has the support head 16 and a formwork support 18. The tube 72 (see FIG. 9) is at least partially, in particular completely, inserted into the formwork support 18. The formwork support 18 has a connecting plate 74. The connecting plate 74 is partially insertable into connecting tabs 78a-d of the support head after rotation about the longitudinal axis 76 of the formwork support 18. The connecting area 54 (see FIG. 9) forms a bayonet receptacle 80 as a result of the connecting tabs 78a-d.

(34) FIG. 11 shows the ceiling support 14 in the mounted state. For anti-twist protection of the connecting plate 74 in the bayonet receptacle 80, the ceiling support 14 has at least one screw connection 82a, 82b between the formwork support 18 and the support head 16. At least one connecting tab 78a-d, in the present case the connecting tabs 78a, 78c, preferably has/have a recess, in the present case the recesses 84a, 84b, for locking a screw nut, in the present case the screw nuts 86a, 86b. The screw nuts 86a, 86b therefore do not have to be secured when the screw connections 82a, 82b are established.

(35) FIG. 12 shows the ceiling support 14 according to FIG. 11 in a top view. It is apparent from FIG. 12 that the support head 16 has through recesses 88a-d in the support plate 20 for placing the screws of the screw connections 82a, 82b.

(36) For setting down a beam 90 (see FIGS. 13-15) in a center position of the beam 90, i.e., for additionally supporting the beam 90 away from its longitudinal side ends, a spacer protrusion 89 is provided on the support head 16. The spacer protrusion 89 is preferably part of the tube 72 (see FIG. 9). The spacer protrusion 89 is situated between the spacer tab pairs 42, 44.

(37) FIG. 13 shows the support head 16 and a beam 90 to be situated on the support head 16. The beam 90 has a first hook 92 in the form of a curved finger. The first hook 92, with its end protruding from the beam 90, is inserted into the first beam insertion area 56.

(38) FIG. 14 shows the support head 16 with the beam 90 completely situated on the support head 16. The beam 90 is supported on the support plate 20.

(39) FIG. 15 shows the support head 16 with the beam 90 vertically lifted. It is apparent from FIG. 15 that the first hook 92 has an interior bevel 94 that is angled with respect to the longitudinal axis 96 of the beam 90. The bevel 94 is designed in such a way that the beam 90 in the mounted state is pulled by its weight force toward the center of the support head 16. The beam 90 may thus be mounted on the support head 16 with a clearance fit, resulting in a defined seat of the beam 90 relative to the support head 16 in the mounted state of the beam 90.

(40) FIG. 16 shows multiple ceiling formworks 10. The ceiling formworks 10 have multiple identical formwork elements 12 and multiple identical support heads 16, the support heads 16 being illustrated only schematically. In addition, only some of the support heads 16 are provided with a reference numeral for reasons of clarity. FIG. 16 illustrates the situation, among others, that only one formwork element rests on a support head 16 (see arrow a). The support head 16 is engaged (see the support head 16a according to FIG. 5), so that the formwork elements 12 may rest flush against a wall 98. The support heads 16 are designed for accommodating formwork elements 12 having different orientations. Adjacently situated formwork elements 12 may be rotated by 90 relative to one another on the support head 16 (see arrows b).

(41) Considered in an overview of all figures of the drawing, the invention relates to a support head 16, 16a-f and a ceiling support 14. The support head 16, 16a-f in particular has a plate-shaped design and has multiple guide tabs 26a-d, 30a-d. The guide tabs 26a-d, 30a-d are arranged or provided in such a way that a formwork element 12 may be placed on the support head 16, 16a-f so as to prevent shifting, preferably at various positions. The support head 16, 16a-f has widely opened first guide tabs 26a-d that are situated opposite from less widely opened guide tabs 30a-d. This asymmetry of the support head 16, 16a-f allows the support head 16, 16a-f to be situated close to a wall corner, while at the same time the formwork element 12 can be easily fastened. The support head 16, 16a-f, in addition to the guide tabs 26a-d, 30a-d, preferably has at least one beam insertion area 56, 60 with a lateral guide 58a, 58b, 62a, 62b, in particular in the form of lateral guide tabs. The guide tabs 26a-d, 30a-d and/or the beam insertion area 56, 60 are/is preferably arranged or provided on a support plate 20, wherein the top side of the support plate 20 facing away from a connecting area 54 of the support head 16, 16a-f forms a support plane 22. The invention further relates to a ceiling formwork 10 comprising such a support head 16, 16a-f, a formwork element 12, and/or a beam 90. In order to put up the ceiling formwork 10, a formwork element 12 with its first end is preferably suspended from below, between the first guide tabs 26a-d of two support heads 16, 16a, 16d that are fastened to formwork supports 18. Two further support heads 16, 16c, 16f that are fastened to formwork supports 18 are subsequently affixed to the formwork element 12 by means of the second guide tabs 30a-d. The formwork element 12 is subsequently swiveled up, and in the swiveled-up state may then be held by the ceiling supports 14.
