Definitions
- the invention relates to an extension board, in particular for installation in in-situ concrete formwork, according to the preamble of claim 1.
- Planks of the type mentioned here include wooden boards, laminated beams, plywood panels and the like., Which have different cross-sections, but in particular a rectangular cross-section of about 45 x 280 mm, both elongated and square cross-sections can be provided.
- a generic extension board in particular for the lining of concrete elements, has a floorboard with a substantially rectangular cross-section and at least one slip-on element arranged displaceably in the longitudinal direction on the floorboard.
- the slip-on can be moved along the plank length, so that one end of the Aufsteckelements changed when moving on the plank, the total length of the extension plank.
- the slip-on element has a substantially C-shaped profile whose essentially rectangular inner cross section is at least slightly larger than the outer cross section of the plank.
- the plank can serve as a guide for the slip-on element, wherein the part of the plank lying in the profile in a form-fitting manner displaceably fixes the slip-on element so that it can only be moved along the longitudinal axis of the plank.
- the C-shaped profile surrounds the board substantially completely on three sides along the circumference and with two flange-like sections, which rest on a further side. This ensures that the slip-on can be moved along an axis on the plank.
- the displaceability of the slip-on element can be correspondingly restricted, for example, by means of a device for fixing the slip-on element on the plank. This makes it possible to adjust the length, which have the floorboard and the slip-on, according to the formwork requirements.
- the means for fixing may be arbitrary, for example in the form of at least one recess in the slip-on element, which can be engaged by a fixing element.
- a fixing element preferably nails are beaten, whereby the plug-on element is fixable to the board.
- the attachment of the Aufsteckelements can also be made via screw, wherein in the region of the recess directly or indirectly, an internal thread is arranged through which a Fixierele- screwed is ment. It can be made in a simple manner, a releasable connection between the male element and the floor, for example, by a mother is welded over one of the recesses into which a screw can be screwed.
- the arrangement of the recesses is provided primarily in the areas of the slip-on, which are located in the region of the inserted plank. It is particularly preferred to arrange the recesses in the region of the flange-like sections, since this side corresponds to the side facing away from the concrete.
- a particularly preferred embodiment provides to connect the flange-like portions of the slip-on element via at least one strut element.
- the distance between two recesses, which are arranged on a respective flange-like portion be fixed by the strut element, which increases the strength of the stretched formwork.
- the end of the slip-on element can basically be designed in any desired form, but in one exemplary embodiment it is provided that a connection plate is arranged at the end of the slip-on element.
- a connection plate is arranged at the end of the slip-on element.
- this connection plate can be used to fix a further floorboard on the drafting board.
- connection plate is arranged on the slip-on element.
- a corner element can be formed in that the connection plate is arranged at right angles to the slip-on element, so that the profile thereof is essentially completed.
- connection plate can be connected to the slip-on.
- the connecting plate and the slip-on are made in one piece.
- the connection plate For this purpose, it can be folded from a region of the slip-on element.
- a weld can make the connection between the slip-on element and a connecting plate arranged thereon.
- fixation of other planks on the extension board can be made with the known formwork techniques, wherein, however, j edoch in a particularly preferred implementation in the connecting plate at least one recess is provided, which isteurgreifbar by a fixing. Through these recesses it is possible, for example, to hammer in nails so as to fasten the connecting plate and the other floorboard to each other.
- a particularly preferred embodiment provides that in the region of the recesses indirectly or directly an internal thread is arranged, through which a fixing element can be screwed.
- a fixing element can be screwed.
- the further floorboard can be fixed to the connection plate in a similar manner as the floorboard to the slip-on element, for example by using screw-fastened elements.
- the connecting plate has a surface which corresponds at least twice the floor cross section, a frictional, surface connection of the connecting plate and the floorboard or a sufficient hold of both parts can be ensured in a simple manner.
- Figure 1 is a schematic side view of an inventive slip-on.
- Figure 2 is a top view of an inventive slip-on element according to Fig. 1.
- 3 shows the slip-on element according to FIGS. 1 and 2 from the left side view perspective;
- Fig. 4 is a side view of the invention embarking according to FIGS. 1 and 2 from the right.
- Fig. 1 shows a slip-on element 1 from the side, wherein a plank can be inserted from the left over the entire length.
- a connecting plate 2 is provided, which limits the slot for a plank in the slip-on and what an additional floorboard can be connected.
- FIG. 2 shows the top view of the slip-on element from FIG. 1, the slip-on element 1 having on the upper side two flange-like shoulders 3 on which the recesses 4 are provided.
- Mounting and fixing elements can be provided in the recesses 4 in such a way that, when a plank is inserted from the left into the slip-on element, it is fixed with fixing elements provided in the recesses 4.
- An inserted from the left into the slip-on element 1 plank can be inserted through the right arranged connection plate 2 only for a maximum length corresponding to the slip-on.
- Fig. 3 shows the left side view of the Aufsteckelements 1 shown in Fig. 2, wherein the C-shaped profile of the Aufsteckelements 1 is shown, which is formed at the top by two flange-like portions 3.
- the connecting plate 2 is in turn broken by recesses 5, which are usable for fixing a further plank.
- Fig. 4 shows the side view of the Aufsteckelements of FIG. 2 from the right view perspective, wherein the connecting plate 2 and the recesses 5, which serve to fix the other floorboard, are shown.
- the embodiment of the invention is not limited to the embodiments described in FIGS. 1 to 4, but also in a variety of variants is possible, in particular, the profile in the nature and size of the formwork requirements can be adjusted ,
