Abstract
A formwork board (3) is made up of at least two formwork board parts (4 and 5) fitting together, whilst the separating line between at least two of the formwork board parts (4 and 5) is defined by abutment webs (12), straps or the like which, in cross section, are located in an inclined position relative to the formwork skin (11) of the formwork board (3) and to the outer edge webs (6) of these formwork board parts (4 and 5). Preferably, the formwork board parts (4 and 5) fit together to form a rectangle. The formwork board part (4) whose abutment web (12) forms an obtuse angle with the formwork skin (11) can be removed first during the stripping of the forms, thus producing a correspondingly wide form-removing gap. The removal of the first part (4) of the formwork board is made easier by the wedge shape resulting from the inclined arrangement of the abutment web (12). Thus, the forms can readily be removed even between two outgoing walls, in shafts or the like. <IMAGE>
Description
SPECIFICATION
Formwork board
The invention relates to a formwork board comprising a formwork skin and webs extending at right angles to the formwork skin, the webs forming end faces at the edges of the formwork board and having points of attachment for securing the formwork board to adjacent formwork boards, the formwork board consisting of at least two parts which are wedge-shaped at least in certain areas, to facilitate the removal of the forms.
A formwork board of this kind is disclosed in
German Patent 1264735. In this patent, two wedge-shaped formwork boards are provided which, in the operating position, together form a rectangle. Longitudinal displacement of a wedgeshaped formwork board of this kind loosens the formwork and especially internal formwork, during the removal of the forms. However, this is only possible if there is enough space for the longitudinal displacement of a wedge-shaped formwork board in the longitudinal direction of the formwork. Furthermore, removal of such forms is difficult in any case, in spite of the wedge-shaped construction, since the longitudinal displacement has to be effected parallel to the plane of concreting, with the result that forces of adhesion between the concrete and the wedge-shaped formwork board may offer considerable resistance to displacement.
The object of the invention is to provide a formwork board which can be removed from the concrete without difficulty and which facilitates the removal of the forms, for example, between two outgoing walls, in shafts or the like, without any need for displacement in the plane of concreting.
According to the invention, there is provided a formwork board comprising a formwork skin and webs extending at right angles to theformworkskin, the webs forming end faces at the edges of the formwork board and having points of attachment for securing the formwork board to adjacent formwork boards, the formwork board consisting of at least two parts, the separating line between at least two of said parts being defined by planar members which are inclined relative to the formwork skin and the webs.
Consequently, owing to the overall wedge-shaped cross section of one of the parts of the formwork board, during removal of the forms it is easy to move the wedge-shaped part away from the concreted surface, thus making room for the removal of the other formwork boards. A formwork board of this kind can therefore facilitate the stripping of the forms even if a limitation, such as a ceiling or the like, for example, is immediately adjacent to the formwork board preventing longitudinal movement.
Advantageously, when the formwork skins of the parts of the formwork board are in alignment, the securing points provided on the planar members coincide and are in the securing position. The planar members, for example in the form of abutment webs, may contain holes for through-bolts or other securing means. Appropriately, the holes in the planar members correspond in shape and size to those in the edge webs of the formwork board.
Manufacture of the formwork board is made easier if the separating line or lines extend parallel to the edges thereof in a plane parallel to the plane of the formskin. Certainly, it would be possible for the separating line to extend diagonally, so that the formwork parts would not only have a wedgeshaped cross section but would also have a wedgeshaped longitudinal construction, but this is not necessary, since the direction of movement for detaching the wedge-shaped part of the formwork board which widens away from the concreted surface may occur away from the concreted surface.
The parts forming the formwork board may be of different widths and a pianar member of at least one part may enclose an obtuse angle with the formwork skin adjoining its edge nearest the concrete. This enables a broad part to widen out in cross section away from the formwork skin, so that this broad part is removed first from the formwork assembly. The form-removing gap thus formed is correspondingly large. It is particularly advantageous if a planar member of the larger part of the formwork board encloses an angle of 135 with the formwork skin, whilst the planar member of another part of the formwork board encloses an angle of 45" with its formwork skin.This produces, on the one hand, a favourable taper for the formwork part which is to be removed first and also makes production easier, since as a rule an angle of 45" is particularly easy to measure out and construct. Moreover, these webs are also made relatively accessible for the securing members.
The planar member of a narrower part or parts of the formwork board may extend from the formwork skin to the outer edge web. As a result, such a formwork part has a virtually triangular cross section, so that a wider formwork part can make optimum use of the total width of the formwork board, so as to permit the largest possible formremoving gap.
The overall width of the parts in the operating position may correspond to a standard grid measurement used in the building industry, preferably about 25 cm. This will then enable the formwork boards to fit the standard dimensions used in building.
The invention is hereinafter explained in more detail, with its essential features, with reference to the drawings, wherein:
Figure 1 is a schematic plan view of a formwork in the region of two outgoing walls;
Figure 2 is a cross section, on an enlarged scale, through an embodiment of a formwork board according to the invention;
Figure 3 is a schematic view of a ceiling formwork, wherein the formwork board of Figure 2 is provided for forming a form-removing joint; and
Figure 4 is a view corresponding to Figure 2, but of a modified embodiment.
During removal of formwork 1 between two outgoing walls 2, in shafts or the like, problems may arise in removing the forms, on account of the pressures occurring during concreting.
In the first exemplary embodiment, shown in
Figure 2, a formwork board 3 is provided inside the formwork 1, said formwork board 3 consisting of two parts 4 and 5 which are partially wedge-shaped in construction (as will be described hereinafter) and which fit together to form a formwork rectangle. The formwork board 3 is provided, on its edges, with webs 6 forming end faces and extending at right angles to the surface which is to be concreted, these webs having points of attachment for securing to the adjacent formwork boards 7. This is clearly shown in
Figure 2, in which these points of attachment are in the form of holes 8 for through-bolts 9.
According to the invention, the separating line 10 between the two parts 4 and 5 of the formwork board is defined by abutment webs 12 which, in cross section, are located in an inclined position relative to the formwork skin 11 and to the outer edge webs 6, whilst, in the illustrated embodiment, abutment webs 12 formed from flat iron are provided. In the illustrated embodiment, at least the abutment web 12 of the wider part 4 of the formwork board is continuous over its entire length. Advantageously, this is also true of the abutment web 12 of the narrower part 5 of the formwork board. However, for connecting the two parts 4 and 5, it may also be sufficient to provide only web portions, i.e. individual straps or the like, in certain areas, so as to make room for a point of attachment 13.When the formwork skin 11 of the two parts 4 and 5 is in alignment, the points of attachment 13 on the abutment webs 12 adjoining the separating line 10 coincide with one another and are in the securing position, the points of attachment 13 in the embodiment by way of example consisting of holes for through-bolts 9. The holes in the abutment webs 12 correspond in shape and size to those provided in the edge webs 6,so that the through-bolts 9 can be the same for both methods of securing. This makes storage easier.
Since the removal of the forms starts by releasing the appropriate connections and then removing the part 4 in the direction of the arrow Pf 1 (Figures 2 and 3), to allow the removal of the forms the separating line 10 of the formwork board 3 may extend parallel to the edges and edge webs 6 thereof in the direction perpendicular to the plane of the Figures.
The abutment webs 12, like the edge webs 6, may be provided with keyhole-shaped holes 8 and 13, respectively, for the securing bolts 9, whilst these bolts 9 may be provided, on the one hand, with cross-pins 14 and, on the other hand, with a counter-stop 15 for holding together the abutment webs or edge webs coming into contact, these bolts being capable of being rotated into the securing position shown, after being inserted. Thus, here again, the securing bolts 9 already available for use with numerous formworks of this kind may also be used for assembling the formwork board 3 and also for securing the two parts 4 and 5 to each other.
The two parts 4 and 5 constituting the formwork board 3 are of different widths in the embodiment by way of example and the abutment web 12 of the wider part 4 encloses an obtuse angle with the formwork skin 11 adjoining its edge 16 nearestthe concrete. In the embodiment shown, this angle is 135 . The abutment web 12 of the narrower part 5 of the formwork board thus encloses an angle of 45 with its formwork skin part, so that the two webs 12 abut on each other in the operating position and form the required abutment whilst simultaneously reinforcing the two-part formwork board.
Figures 2 and 3 also clearly show that the abutment web 12 of the narrower part 5 of the formwork board extends from the formwork skin 11 substantially to the outer edge 17 of the associated edge web 6, with the result that the narrower part 5 of the formwork board is virtually triangular in cross section. As a result, this part is made relatively rigid, so that its additionai reinforcement will at least partially compensate for any weakening of the formwork board 3 caused by the separating line 10, and in addition the wider part 4 of the formwork board is thus made as wide as possible, resulting in a correspondingly large form-removing gap after it has been removed.
In the exemplary embodiment, the formwork skin 11 of the two parts 4 and 5 consists of sheet metal.
As a result, the abutment webs 12 can be securely attached thereto, e.g. by welding.
Figures 1 and 2 show that the formwork tie rods 18 may each extend in the region of the edge webs 6 of the formwork board 3, so that the wing nuts 19 partly engage over the formwork board 3. On removal of the forms, first these wing nuts 19 are released, followed by all the connecting bolts 9 along the inclined separating line 10. The through-bolts 9 on the edge webs 6 of the wider part 4 of the formwork board are then removed. This formwork part 4 can then be removed in the direction of the arrow Pf 1, i.e. in a slightly inclined direction relative to the concreted surface, this movement being made easier by its tapering shape in this cross sectional direction. After this part has been removed (cf. the illustration shown in broken lines in Figure 2), a sufficiently large form-removing gap is formed which enables the remainder of the formwork 1 to be removed without any difficulty.Longitudinal displacement along the concreted surface is avoided.
The embodiment according to Figure 2 shows a formwork board which, as described, comprises two parts 4 and 5 which are releasably connected at the inclined separating line 10, in the operational position. Figure 4 shows a modified embodiment of independent significance. Like parts, even when slightly modified, have been given the same reference numerals as in Figure 2, in the interests of clarity.
In this embodiment, the formwork board comprises three parts 4, 5 and 5a and has two separating lines 10 which, in cross section, extend diagonally away from the formwork skin 11 and from each other, the three parts 4, 5 and 5a being releasably connected along the separating lines 10. In the illustrated embodiment, the two separating lines 10 are arranged symmetrically relative to a centre line
M extending at right angles to the formwork skin.
Thus, the removal of the forms may be effected virtually exactly at right angles to the concreted surface, in the direction of the arrow Pf 2.
This arrangement comprising a central formwork board part 4, which substantially corresponds to an equilateral trapezium in cross section, has major advantages particularly for use in shaft formwork when the clamping points on the edge webs 6 are not arranged symmetrically, viewed in the longitudinal direction of the formwork board.
