Compensating ceiling formwork element for building around an obstacle

Abstract

A formwork element of a ceiling formwork. The formwork element has a non-fully circumferentially closed, in particular U-shaped, frame onto which a formwork skin can be or is arranged. The frame preferably has at least a first leg, a second leg and a base strut in between. The base strut is preferably oriented at a right angle ±5° relative to the two legs. The legs are preferably each provided at their end regions opposite to the base strut with a fastening projection and/or a fastening recess. The formwork element can be suspended by a worker from below into a pillar head and is upwardly pivotable. It makes it possible to build around an obstacle in a simple manner while maintaining a grid-like imprint structure in the concrete surface to be created with the ceiling formwork.

Description

(1) Further features and advantages of the invention are presented in the following detailed description of an exemplary embodiment of the invention, in the claims and in reference to the figures of the drawing, which show details that are essential to the invention. The various features can each be realized in variants of the invention individually or by any combination of multiple features. The features shown in the drawing are depicted in such a way that the special features according to the invention can be made clearly visible.

(2) Shown are:

(3) FIG. 1 a perspective view of a ceiling formwork with a plurality of standard formwork elements and a first formwork element for building around an obstacle in the ceiling formwork;

(4) FIG. 2 a perspective view of the formwork element from FIG. 1;

(5) FIG. 3 a perspective view of the ceiling formwork according to FIG. 1 with a fully inserted formwork element;

(6) FIG. 4 a perspective view of the ceiling formwork according to FIG. 3 with an attached second formwork element;

(7) FIG. 5 a perspective view of the ceiling formwork according to FIG. 4 with a fully mounted second formwork element;

(8) FIG. 6 a perspective view of a transverse strut; and

(9) FIG. 7 a perspective view of the ceiling formwork according to FIG. 5 with a plurality of inserted transverse struts according to FIG. 6.

(10) FIG. 1 shows a ceiling formwork 10. The ceiling formwork 10 has a plurality of standard formwork elements 12a-12e supported on a plurality of pillars, of which only a first pillar 14a is provided with a reference character in FIG. 1 in the interests of clarity.

(11) More precisely, the ceiling formwork 10 has a pillar head 16a on the upper end of pillar 14a, on which the standard formwork elements 12a-12e can rest, wherein in the case of the pillar head 16a, the standard formwork element 12a is supported.

(12) As is clear from FIG. 1, the erection of the ceiling formwork 10 is prevented by an obstacle 18, in this case in the form of a column. A formwork element 20a that is partly visible in FIG. 1 allows the sealing enclosure or building around of the obstacle 18 in a simple manner according to the invention.

(13) FIG. 2 shows the first formwork element 20a alone. The first formwork element 20a has a first frame 22 with a U-shaped design. The frame 22 is constructed from a metal profile, in particular in the form of an aluminum profile. The frame 22 has a first leg 24, a second leg 26 and a base strut 28 between the two legs 24, 26. The first leg 24 is connected to the base strut 28 via a first connecting strut 30. The second leg 26 is connected to the base strut 28 via a second connecting strut 32.

(14) The frame 22 has a step 34, on which a formwork skin 36 can be arranged. The formwork skin 36 is represented only partly in FIG. 2 and diagrammed in the interest of clarity. The formwork skin 36 is arranged in a formwork skin layer 38. In the interest of clarity, the formwork skin 36 is not represented in FIG. 7.

(15) To suspend the first formwork element 20a in a pillar head (see, for example, FIG. 1: pillar head 16a), the frame 22 in the region of each of the end regions of the legs 24, 26 opposite to the base strut 28 has a fastening projection, of which, for the purposes of perspective representation, only a first fastening projection 40 is provided with a reference character in FIG. 2.

(16) FIG. 3 shows the ceiling formwork 10, wherein the first formwork element 20a, in contrast to the representation according to FIG. 1, has been fully pivoted from below. The support of the formwork element 20 is accomplished via a pillar head 16b that is on a pillar 14b. A second fastening projection 42 (see FIG. 2: first fastening projection 40) is incorporated in the pillar head 16b in such a way that the first formwork element 20a can no longer be moved relative to the pillar head 16b perpendicular to the longitudinal axis of the pillar 14b, i.e. parallel to the formwork skin layer 38 (see FIG. 2).

(17) FIG. 4 shows the suspension of a second formwork element 20b in the pillar head 16b. The second formwork element 20b has a design identical to the first formwork element 20a. The first formwork element 20a and the second formwork element 20b can be completely mounted from below, whereby the occupational safety during the erection of the ceiling formwork 10 is substantially increased.

(18) FIG. 5 shows the support of the second formwork element 20b via pillar heads 16c, 16d, which are arranged on the pillars 14c, 14d. The formwork element 20b is thus underlain in its two corner regions by the U shape.

(19) FIG. 6 shows a first transverse strut 44a for reinforcing the formwork elements 20a, 20b (see FIG. 7). The first transverse strut 44a can preferably be reversibly releasably connected to the frame 22 (see FIG. 2). More preferably, the first transverse strut 44a can be screwed to the frame 22 (see FIG. 2). Alternatively or additionally, the first transverse strut 44a can be held at least partly positively engaged on the frame 22 by a guide (see FIG. 2).

(20) FIG. 7 shows the ceiling formwork 10 with the formwork elements 20a, 20b, wherein the formwork elements 20a, 20b have a plurality of transverse struts 44a-44d. The transverse struts 44a-44d, moreover, assist the support of the formwork skin 36 (see FIG. 2), which can be laid directly on longitudinal sides of the transverse struts 44a-44d. The transverse struts 44a-44d are ideally mounted before the mounting of the formwork element 20b.

(21) When viewing all figures of the drawing together, the invention relates collectively to a formwork element 20a, 20b of a ceiling formwork 10. The formwork element 20a, 20b has a non-fully circumferentially closed, in particular U-shaped, frame 22 onto which a formwork skin 36 can be or is arranged. The frame 22 preferably has at least a first leg 24, a second leg 26 and a base strut 28 in between. The base strut 28 is preferably oriented at a right angle ±5° relative to the two legs 24, 26. The legs 24, 26 are preferably each provided at their end regions opposite to the base strut 28 with a fastening projection 40, 42 and/or a fastening recess. The formwork element 20a, 20b can be suspended into a pillar head 16a-16 by a worker from below and can be pivoted upward. It makes it possible to build around an obstacle 18 in a simple manner while maintaining a grid-like imprint structure in the concrete surface to be created with the ceiling formwork 10.
