Description
~7~
The present inven$ion relates to an improvement of the shutterings described in my copending application Serial No. 226, 092.
As becomes clear from that specification panels are provided with grooves extending near an edge of a panel and two panels laid side by side with their grooves in parallel are firmly connected by means of a rail of a specific profile which includes "tongue poxtions~ engaging in the said groove. In the construction according to the said pater.t application different means have to be provided for panels to be connected co-planarly and for those to be connected at an angular relation to one another. Co-planar connections are employed for shutterings used in castingthe major face of a wall or the like; the angular connection is required when the corner of a building structure, or a pillar is to be cast.
A~ further improvement concern~ the following: As has been explained in the description of the invention according to mSr said ~;
patent application the rails may be slid lengthwise into the grooves provided in the panels. For certain purposes and in some location such sliding in of the rails would at least be awkward, if not impossible. Therefore it had been proposed to make the tongues on the rails narrower across than the grooves into which they are to be inserted" Thus a narrow tongue may enter a groove of a panel sideways, eliminating thereby the need of sliding in a long rail the length of which might make this operation diffi-~ult.

In such a case clamping means are required to forcibly urge together the rails in the grooves of two vicinal panels, The present application relates to such an improved clamping means9 Incidentally, such clamps can fulfil a further, important task.
It is the object of the present invention to pxovide panels and connecting rails which may be used as shutterings for concrete structures to be cast therein, the panels being connectable by means of the same rails, both co-planarly and in angular relation to one another, It is a further object of the invention to provide an improved clamp for the purpose referxed to above, According to the present improvement each panel is provided along at least one edge thereof with two parallel grooves and the rails for connecting the panels are provided with profiled portions fitting into either of the grooves, means being provided on the said rails for forcibly urging the panels towards one another whenever the said profiled portions of the rails are engagingly inserted în the grooves of the two panels.
The invention will now be described in detail with reference to the accompanying dxawings, wherein the n~w construction is shown schematically.

The invention will now be described in detail with reference to the accompanying dxawings, wherein the n~w construction is shown schematically.
Figs. 1 and 2 are both cross sectional views of the improved panel connections. Figo 1 shows the angular relative position and Fig. 2 the co~planar position of connected panels.

Figs, 3, 4 and 5 illustrate schematically the improved c onne ction.
Fig. 6 is a perspective view9 on a larger scale of an improved clamp.
Fig. 7, is a perspective view of a form of such a clamp for special use.
Fig. 8 is a like view of another clamp destined for use in cases where very wide panels are to be held to one another.
Fig. 9 illustrates schematically an incidental, additional use of the new clamps.
Turning first to Figs, l and 2: Two panels l and 2 are each provided near an edge thereof with two parallel grooves 3 and 4, Groove 3 is undercut (but need not be so) while groove 4 is a V-groove (but need not be so)~
A rail 5 having a profiled tongue 51 can engage with that portion 51 in either of grooves 3 or 4, A profiled tongue member 6 is of same profile as portion 5s and thus can also engage in either of the t~wo grooves. To member 5 is attached a bar 71 the end 7~ of which is formed as a presser foot. To bar 7 is turnab~r - about an axis 8 ,- affixed a cam 9 which can be turned by a handle lO, In Fig. l "tongue" portion 51 engages in groove 4 of panel 2, while member 6 engages in groove 3 of panel l" The panels l and
2 are positioned to define a right angle between them. Presser foot 7t lies against the outside of portion 5~, The cam 9 lies against the rear of member 6. By turning the cam 9 by means of handle - 4,--10 strong pressure is exerted on both, member 6 and portion 5~
(onto the latter by presser foot 7~), thereby firmly urging the two panels 1 and Z against one another and rigidly connecting them.
In Fig, 2 the two panels are placed in a common plane and abut against one another with their edges, In this case both portions 5 and member 6 engages in grooves 3 of panels 1 and 2, Again pressure is exerted by means of cam 9 as has been described above.
It will be seen that identical panels with identical grooves can now be connected with one another in different relative positionsO
There are possible certain variations of construction without departing from the gist of the invention~ While the cam mechanism shown and described permits a quick and secure connection, it would be possible to use different means, So e, g. pressure might be exerted by screw or by clamps urging the panels towards one another, Equally the profiles of portion St and member 6 may be different, say square - in which case the grooves 3 and 4 will be of corresponding cross sectional shape, The rails 5 and 6 may be of whatever length, As can be seen from Figs. 3 and 4, the rails are inserted sideways into thc grooves~, Then by means of bar 7 and presser foot 7~ which are actuated by cam 9~ the two panels are forcibly pulled together (as indicated by the arrows in Figs, 3 and 4), 7~6~1L
At the same time pressure is exerted on both panels in the direction of the upwardly pointing arrows in Fig~, 4, As a result the two panels become co_planarly aligned, as is required in a shuttering.
Fig. 5 shows in the same manner the use of the improved connecting means applied to angularly connected panels.
The perspective view of Fig. 6 does not require further description, the clamping member having been described in full ab ove .
As is well known, the two walls of a shuttering are connected by ties which span the distance between the said two walls. It is common practice to drill holes in the planks which form the shuttering, to provide a hold for the ties. l~rilling holes into planks or panels of the kind of this invention would be inconvenient, the panels are destined for repeated use and should not be defaced by drilled holes. It ;s suggested the3refore to interpose between two panels an expendable narrow timber plank or fillet into which holes may be drilled and which can be discarded after one or a few uses. So that this can be done the implement according to Fig. 7 is used. Here the bar 7 is of such a length that it is adapted to span a distance between two panels. In that case a narrow timber strip or fillet can be inserted between the panels and is held there-between when the panels are forcibly urged towards one another It will be understood that the new clamp may either be permanently attached to the rails (as e. gO shown in Fig. 7~ or rnay be a separate unit (as shown eO g. in Fig. 6), - 6 ~-~7~
Turning now to Fig. 8, here a bar 70, the free end of which is formed as a rack, serves instead of bars 7 described above.
C)ne of the rails, indicated by numeral 50 can be urged into clamping position by cam 9. The second rail 60 is shiftable on bar 70 and can be fixed in a desired position by a pawl 61 engaging the rack portion of bar 70., Such devices are well known and require no further elucidation.
Fig~ 9 illustrates the use of the devices of Figs. 7 and 8.
At the left hand end of the wall which is cast in a shuttering comprising panels ,a at one and panels b at the opposite side, a clamping device c is provided. This device is one identical with that shown in Fig. ~,, Between the two outermost panels ,a and b at that end of the shuttering is held a timber plank d constituting the end closure of the shuttering, ~Lll panels ,a and all panels b are clamped together by clamying devices ,e which are identical with that shown in Figr 7, Between vicinal panels - both ~a and b are inserted wooden fillets f and are clampingly held between the edges of the respective panels. ~Ioles are drilled into these fillets - as mentioned above and tie rods ,~ are passed there ,-through and are secured at the outside of the shuttering by screwed on nut, as is well known~ Onto rods ,~ are slipped short pieces of tubes h which serve as distance pieces between opposite pane 1 s, 7,,
(onto the latter by presser foot 7~), thereby firmly urging the two panels 1 and Z against one another and rigidly connecting them.
In Fig, 2 the two panels are placed in a common plane and abut against one another with their edges, In this case both portions 5 and member 6 engages in grooves 3 of panels 1 and 2, Again pressure is exerted by means of cam 9 as has been described above.
It will be seen that identical panels with identical grooves can now be connected with one another in different relative positionsO

Fig. 5 shows in the same manner the use of the improved connecting means applied to angularly connected panels.
The perspective view of Fig. 6 does not require further description, the clamping member having been described in full ab ove .
