Definitions
- the present invention concerns a connecting piece for sheetings, in particular for concrete forms.
- the invention concerns a connecting piece for sheetings which is mainly formed of a supporting element which can work in conjunction with a first sheeting and which is provided with position finding means. It also comprises a coupling element which is also provided with position finding means and which can work in conjunction with the position finding means of the supporting element; and connecting means which provide for the connection between the aforesaid coupling element and a second sheeting.
- Such connecting pieces are already known, for example from BE 905030 , whereby the supporting element is mainly formed of a flat body and the position finding means are formed of at least one recess in a side of this body, whereas the coupling element is mainly formed of a flat body whereby the position finding means are formed of a protrusion provided on one side of said flat body which can work in conjunction with the aforesaid recess.
- connecting pieces are advantageous in that sheetings can be coupled to each other to a centimetre accurately.
- the sheetings are usually provided with a series of holes, 5 cm apart from one another, to be coupled to each other.
- the sheetings can also be coupled to one another according to intermediate distances that do not correspond to the aforesaid holes with 5 cm in between them.
- the connecting means with which the sheetings are coupled to one another must often be entirely disassembled to put the supporting element and the coupling element in the required position, for example as the coupling part must be turned with its other side to the supporting element for certain positions.
- Another disadvantage of the known connecting pieces is that the distance between the successive positions of the coupling element in relation to the supporting element is determined by the distance between the protrusions and the grooves, which results in a not so fine alignment.
- protrusions are rather weak, such that they break off easily.
- the present invention aims to remedy one or several of the aforesaid and other disadvantages.
- the present invention concerns a connecting piece of the aforesaid type whereby the position finding means are formed of two parallel teeth on at least one of the aforesaid elements, shifted half a pitch in relation to each other, and of at least one tooth provided on the other element, whereby, when the coupling element is pointed in a first direction in relation to the supporting element, as a result of an axial movement of the coupling element towards the supporting element, the aforesaid tooth can co-operate with one of both aforesaid parallel teeth in a non-rotating manner and, when the coupling element is pointed in a second direction after a rotation in the aforesaid axial direction, the aforesaid tooth can co-operate in a non-rotating manner with the other teeth of the aforesaid two parallel teeth.
- a major advantage of this connecting piece according to the invention is that the positioning of the supporting element and the coupling element in relation to each other is very simple.
- tooth of one element can co-operate with the two parallel teeth of the other element, such that any position whatsoever can be taken by simply shifting the coupling element in relation to the supporting element and/or by rotating the coupling element in relation to the supporting element.
- Another advantage of a connecting piece according to the invention is that the distance between the successive positions of the coupling element in relation to the supporting element can be smaller than the distance between the successive teeth of the parallel teeth, also called the pitch, since by rotating the coupling part in relation to the supporting element, both parts can be shifted in relation to each other by exactly one half pitch.
- this connecting piece according to the invention is that, in order to position the supporting part and the connecting piece in relation to each other, the connecting means must no longer be entirely disassembled between the sheetings, since all positions can be simply set by shifting the coupling part a few teeth and/or by rotating it in relation to the supporting element.
- the position finding means of one element are formed by an inner toothing and those of the other element by an outer toothing, whereby the outer toothing can be axially shifted in the inner toothing.
- An advantage of this embodiment of a connecting piece according to the invention is that it can be made small and that the coupling element and the supporting element are automatically locked against rotating in relation to each other by shifting them into one another, such that the connecting means can be easily and very efficiently provided on the coupling element.
- the invention also concerns a sheeting which is provided with a metal strut in which a connecting piece according to the invention is or can be integrated, either by welding or by clamping or another jointing technique.
- the sheeting according to the invention is preferably provided with holes which are preferably situated at an equal mutual distance, such that it can be coupled to another sheeting, whereby a reinforcing profile is provided at the holes.
- the sheeting according to the invention with reinforced holes offers the advantage of dimensional stability, as the holes can no longer wear out due to frequent use thanks to the reinforcing profile, which is the case with the known sheetings.
- the connecting piece 1 according to the invention represented in figures 1 to 7, as with the known connecting pieces, is mainly formed of a supporting element 2, a coupling element 3 and connecting means 4.
- the supporting element 2 and the coupling element 3, as is known, are provided with position finding means 5 which can co-operate.
- a specific characteristic of the connecting piece 1 according to the invention is that the position finding means 5 are formed of two parallel sets of teeth 6 and 7 on at least one of the aforesaid elements, in this case the supporting element 2, and of at least one tooth 8 provided on the other element, in this case the coupling element 3.
- the two parallel sets of teeth 6 and 7 of the supporting element 2 have shifted half a pitch in relation to each other.
- the pitch in a toothing is defined as the centre distance D between two successive teeth 9.
- a tip 10 of a tooth 9 of the first set of teeth 6 is situated directly opposite a foot 11 of a tooth 10 of the second set of teeth 7 that is parallel to the latter, and vice versa.
- the coupling element 3 when pointed in a first direction CC' in relation to the supporting element 2, as a result of an axial movement of the coupling element 3 towards the supporting element 2, the aforesaid tooth 8 can co-operate in a non-rotating manner with one of both the aforesaid parallel sets of teeth 6 and 7.
- the aforesaid tooth 8 can co-operate in a non-rotating manner with the other set of teeth of the aforesaid two parallel sets of teeth 6 and 7.
- the aforesaid angle of rotation in the axial direction AA' from the first direction CC' to the second direction CC' amounts to 180°.
- teeth 8 of the coupling element 3 there are several of the aforesaid teeth 8 of the coupling element 3 in the given embodiment, since the tooth 8 is part of two parallel sets of teeth 12 and 13 that have been shifted half a pitch D/2 in relation to each other in the direction CC' of the parallel sets of teeth 12 and 13.
- the position finding means 5 of one element 2 or 3 are formed of an inner toothing 14 and those of the other element 3 or 2 are formed of an outer toothing 15.
- the position finding means 5 of the supporting element 2 in particular are formed of an inner toothing 14, namely the parallel sets of teeth 6 and 7, and those of the coupling element 3 are formed of an outer toothing 15, namely the parallel sets of teeth 12 and 13.
- outer toothing 15 can be shifted in the inner toothing 14 in the axial direction AA'.
- teeth 14 and 15 are complementary and as the tooth flanks 16 of the sets of teeth 6 and 7, as well as of the sets of teeth 12 and 13 extend in the axial direction AA'.
- the inner toothing 14 is provided with more teeth 9 than the outer toothing 15, as a result of which the outer toothing 15 fits in the inner toothing 14 in several ways.
- the supporting element 2 of the connecting piece 1 according to the invention is provided with a collar 17, whereas the coupling element 3 is provided with a supporting surface 18 with which it rests against the supporting element 2 when in use.
- the connecting means 4 mainly consist of a threaded rod 19, represented in detail in figure 7, which can work in conjunction with a threaded hole 20 in the coupling element 3, and of a nut 21.
- the supporting element 2 is further provided with a central passage 22 provided between the parallel sets of teeth 6 and 7.
- This central passage 22 extends in the axial direction AA'.
- central passage 22 is somewhat elongated in the direction CC' of the parallel sets of teeth 6 and 7.
- Such sheetings 23 typically consist of a metal frame that is built of metal struts 24, whereby a plate 25, such as for example a multiplex plate 25, is provided.
- the plate 25 are usually provided holes 26 in order to couple several sheetings 23 that are provided at a regular distance E of for example 5 cm from one another.
- the supporting element 2 of the connecting piece 1 is first fixed to the crosscut side 27 of a metal strut 24 of a first sheeting 23.
- this part 28 can be provided in a fitting manner in a metal strut 24 on the crosscut side 27 of the sheeting 23, whereby a collar 29 is further provided to make the supporting element 2 rest on the metal struts 24 and 27.
- the supporting element 2 is preferably welded onto the metal strut 24 and 27, but other jointing techniques are not excluded however.
- the coupling element 3 is provided on the supporting element 2 together with the connecting means 4, whereby the connecting means 4 provide for the connection between the aforesaid coupling element 3 and a second sheeting 23.
- the threaded rod 19 is hereby provided through one of the holes 26 of the second sheeting 23, whereby it is further put with one far end 30 through the central passage 22 of the supporting element 2 and is screwed down in the threaded hole 20 of the coupling element 3. With its other far end 31, it is clamped against the second sheeting 23 by means of the nut 21.
- a sheeting 23 according to the invention is provided with a reinforcement in the form of a metal strut 32 behind the holes 26.
- the holes 26 in the second sheeting 23 have been provided with a certain intermediate distance E of for example 5 cm, such that in order to couple the first sheeting 23 to the second sheeting 23 with a greater precision than the aforesaid distance E, for example with a precision of 1 cm, provisions must be made to realize the coupling at an intermediate distance.
- the coupling element 3 and the supporting element 2 are each provided with cooperating position finding means 5.
- the outer toothing 15 of the coupling element 3 fits between the inner toothing 14 of the supporting element 2, and the positioning of both elements 2 and 3 in relation to each other in the direction CC' of the teeth is determined by the position of the outer toothing 15 in the inner toothing 14.
- the coupling element 3 points in a first direction CC' and is provided in an utmost position between the sets of teeth 6 and 7 of the supporting element 2 as a result of an axial movement, whereby the tooth 8 works in conjunction with the set of teeth 6 in a non-rotating manner.
- the coupling element 3 is connected to the second sheeting 23 via its threaded hole 20 and the threaded rod 19, whereas the supporting element 2 is fixed to the metal strut 24 and 27 of the first sheeting 23.
- marks can be provided for example on the supporting element 1, as is represented in figures 11 to 14.
- the teeth can be block-shaped or they can be made as a standard set of teeth.
- the invention is by no means limited to the connecting pieces for concrete formworks described as an example; on the contrary, such a connecting piece can be made according to all sorts of variants while still remaining within the scope of the invention.
