Description

The invention relates to a casing for floors of building parts according to the preamble of independent claim 1 and a casing for floors of building parts according to the preamble of independent claim 2. In particular, the invention relates to a casing for forming a waterproof flooring for balconies, terraces or the like.

Cladding for building parts are already known from the prior art. In particular, formworks are known in which a plurality of shuttering elements spaced to form gaps or joints are arranged to each other, wherein between the shuttering elements in each case a groove is provided to receive on the gaps or joints penetrating liquids and to dissipate suitable.

From the publication DE 200 02 547 U1 is a flooring for open spaces known in which gutters are milled into the planks.

From the pamphlets DE 10 2005 029 933 B4 and DE 298 14 983 U1 Floor coverings have become known in which water drainage profiles are provided between the planks.

The document defining the generic term DE 199 31 810 A1 discloses a step floor for balconies comprising a dewatering element received between a pair of planks fixed in grooves of the planks.

A disadvantage of the known cladding that they often have only insufficient fixation of the gutters on the shuttering elements. This can lead to problems in the laying of the casing, to impact sound and beyond to a leaking of the casing, especially in the case of gushing liquid quantities to be discharged through the channel.

The object of the invention is therefore to show a casing, which has an improved fixation of the grooves on the shuttering elements while increasing the tightness.

The object is achieved on the basis of the preambles of the independent claims 1 and 2 by their characterizing features.

The invention relates to a casing for floors of building parts comprising a plurality of shuttering elements. The formwork elements each have an upper side, a lower side and two mutually opposite side surfaces. To form the shuttering the shuttering elements spaced to form columns or joints spaced from each other on a support and secured in a suitable manner, for example by screwing. Between the shuttering elements in each case a channel is provided with a channel bottom and two gutter legs projecting from the channel bottom. The shuttering elements each have on their underside in the region of a first side surface a first recess or first groove, in which a first compensating belt made of an elastic material is arranged. The first recess or first groove and the groove are dimensioned such that when fastening the shuttering elements, an upper portion of a first channel leg is at least partially pressed into the first compensating band. This ensures that even with tolerances of the support or the shuttering elements or occurring in moisture / dryness swelling movements a permanent entrapment of the first gutter leg between the support and the first compensating strip having shuttering element is achieved. In addition, it is achieved that a permanent sealing of the transition between the first channel leg and the shuttering element is effected by pressing the upper portion of the first channel leg in the first compensating band.

An alternative formwork for floors of building parts comprises a plurality of shuttering elements each having an upper side, a lower side and two opposite side surfaces, wherein the shuttering elements spaced apart to form columns and wherein between the shuttering elements in each case a groove with a groove bottom and two projecting from the groove bottom Trough legs is provided. The shuttering elements each have on their underside in the region of a first side surface a first recess or first groove. On a first channel leg, in particular at the free end of the channel leg, a first compensating band made of an elastic material is arranged and the first recess or first groove and the channel are dimensioned such that when fixing the shuttering elements, the first compensating band in the region of the first recess or first Groove is pressed under deformation of the first compensating band. This in turn ensures that even with tolerances of the support or the shuttering elements or occurring in the case of moisture / dryness swelling movements a permanent sealing of the transition between the first channel leg and the shuttering element is achieved.

In a preferred embodiment, the free end of the first gutter leg is at least partially enclosed by the first compensating band. Thus, the attachment of the first compensating band can be done easily and inexpensively by attaching to the free end of the gutter leg.

In a preferred embodiment, the shuttering elements have on their second side surface opposite the first side surface a second groove in which a second channel leg of the channel can be fixed. This ensures that the gutter is held on both gutter legs, which further increases the fixing effect on the gutter.

Preferably, the second groove is a groove open to the second side surface. It is thereby achieved that the gutter leg, at least in sections, protruding from the gutter bottom, covers the second side surface, so that the rot of shuttering element sections projecting into the gutter interior can be prevented when wooden shuttering elements are used.

In a preferred embodiment, the first channel leg in the region of its free end has a profile section which enlarges the bearing surface in relation to the first compensating strap. This profile section can be formed by a profile section projecting laterally, in particular parallel or substantially parallel to the channel bottom in the direction of the channel interior. By the support surface enlarging profile section is achieved that the first compensating band is not only punctiform, but flat deformed. This lowers the load on the first compensating band and thus its durability. In addition, the tightness of the transition between the groove and the shuttering element is further increased by a projecting in the direction of the channel interior profile section.

The gutter leg portion of the second gutter leg may be fixed in the second groove by gluing. As a result, a fixed fixation of the channel relative to the second groove having shuttering element is achieved. Alternatively, a gutter leg portion of the second gutter leg may be clamped in the second groove.

In a preferred embodiment, the first groove is formed wider than the free end of the first groove leg received in the first groove. This has the advantage that, for example, during swelling and shrinkage movements of the shuttering element having the first groove, there is lateral movement space with respect to the groove, so that deformations or damage to the groove are effectively prevented by these swelling and shrinkage movements.

Preferably, the second channel leg is formed folded. As a result, a channel leg section can be introduced laterally into the groove open to the second side face and fixed by gluing or by clamping action.

Preferably, a channel leg portion of the second channel leg is clamped by a rotational movement of the channel in the bottom region of the second groove. As a result, an effort minimized attachment of the channel in the second groove of the Verschaltungselements is achieved, which can be done on site without additional material, such as adhesive.

Furthermore, preferably, the second channel leg has a rounded edge. This rounded edge comes with the rotational movement of the channel for clamping the same in the groove against a side surface of the groove to the plant and facilitates due to the rounding of the rotational movement of the channel.

In a preferred embodiment, the profile of the second gutter leg is adapted to the profile of the shuttering element in the region of the second side surface between the second groove and the bottom or corresponds to this profile. It is thereby achieved that the second channel leg extends along the preferably stepped second side surface adjacent. This further improves the fixation of the channel on the shuttering element due to the positive connection.

Preferably, the free end of the second channel leg is formed tapering. This allows this free end to penetrate when jamming the channel in the shuttering element, which in turn the fixation of the channel is improved on the shuttering element.

In a further embodiment, a sealing band may be provided in the region of the second channel leg. This sealing tape may be provided, for example, in the bottom region of the second groove and thus lie flat against a gutter leg section. As a result, the tightness of the transition between the second groove and groove in the region of the second gutter leg is improved.

In a further exemplary embodiment, a second compensating strap made of an elastic material which partly surrounds this free end is provided on the free end of the second channel leg. This second compensating band will on the one hand reaches a clamping holder of the second gutter leg in the region of the second groove, since this second compensating band is preferably deformed upon insertion of the free end of the second gutter leg. In other words, the second compensating band is compressed during the introduction of the second channel leg into the second groove such that a clamping of the channel leg in the groove is effected. The second compensating strap is preferably reversibly deformable, so that the clamping force of the second trough arm is achieved by the restoring forces. Furthermore, the compensating band also causes a sealing of the transition between the free end of the channel leg and the upper side surface or the bottom region of the second groove.

The shuttering elements can be made of any suitable materials for the purpose, in particular of wood, a wood-based panel, plastic, a wood-plastic composite material, concrete or metal.

The channel may be formed of any suitable material for the purpose, for example metal, aluminum or plastic.

The first and second compensating tapes and the sealing strip can be formed from any reversibly deformable, elastic materials, in particular vulcanized rubber, sponge rubber, etc. In particular, a swelling tape can be used as compensating tape or sealing tape.

The expressions "approximately", "substantially" or "approximately" in the context of the invention mean deviations from the respective exact value by +/- 10%, preferably by +/- 5% and / or deviations in the form of changes insignificant for the function ,

The basic design of the shuttering element 2 in the area of the second side surface 2.4 corresponds to the second embodiment described above. The shuttering element 2 in particular has a second groove 8th on, extending to the second side surface 2.4 opens. It is preferably in the corner of a fold 11 arranged. This fold 11 causes a stepped formation of the side surface 2.4 , Analogous to the second embodiment, the second groove 8th in the embodiment shown also has a width e, which is a multiple of the material thickness of the Rinnenwandung. In this second groove 8th becomes a folded portion of the second gutter leg 5.3 brought in.

This is the second gutter leg 5.3 formed repeatedly folded. The second gutter leg 5.3 includes, for example, a first trough leg portion starting from the free end 5.3.1 that is perpendicular or substantially perpendicular to the channel bottom 5.1 runs and over a first edge 5.3.4 in a parallel or substantially parallel to the channel bottom 5.1 extending second trough leg section 5.3.2 passes. To the second gutter leg section 5.3.2 over a second edge 5.3.5 then there is a third channel leg section 5.3.3 provided, in turn, perpendicular or substantially perpendicular to the channel bottom 5.1 runs and preferably passes directly into this. The training of the second gutter leg 5.3 is preferably chosen such that the second trough leg 5.3 the profile of the formwork element 2 in the area of the second groove 8th or in the area between the second groove 8th and the bottom 2.2 equivalent. In other words, the gutter leg 5.3 to the course of the shuttering element 2 in a partial region of the stepped side surface 2.4 adapted in shape.

In the area of the free end of the second trough leg 5.3 , ie at the free end of the first trough leg section 5.3.1 is a second compensating band 10 arranged. This second compensating band 10 is preferably formed of an elastic, shape-changeable material. It is preferably the clamping holder of the channel 5 opposite the shuttering element 2 in the area of the second side surface 2.4 , Furthermore, it serves to seal the gutter 5 opposite the shuttering element 2 in such a way that liquid located in the channel interior even in the event that this up to the free end of the second gutter leg 5.3 rises, do not flow over this free end and thus possibly down in the direction of the support 4 or penetrate underlying building areas.

Preferably, the second compensating band 10 a round, oval or polygonal cross-section. The arrangement on the gutter 5 This can be done by making the second compensating band 10 a notch 10.1 or having a cut. This can be the second compensating band 10 on the free end of the second trough leg 5.3 be plugged. It is also possible that on the second compensating band 10 a Aufsteckbereich is provided, especially for attachment to the free end of the second gutter leg 5.3 is trained.

How special in the 7 and 8th shown, the clamping attachment of the channel takes place 5 similar to the second embodiment described above. This is the gutter 5 from a starting position in which the gutter floor 5.1 parallel to the underside of the shuttering element 2 runs, twisted around the trough longitudinal axis, preferably in such a way that the groove bottom 5.1 receiving level and the bottom 2.2 of the shuttering element 2 Receiving plane between them include an acute angle, which is to that of the second side surface 2.4 opposite side opens. In this tilted state, the gutter becomes 5 with the free end of the second trough leg 5.3 ahead into the second groove 8th introduced. Here comes the free end, preferably the compensating band 10 has, in the region of the upper corner of the second groove 8th to lie. Subsequently, the reverse rotation of the channel 5 so that the gutter floor 5.1 in the bottom 2.2 of the shuttering element 2 at the receiving or parallel level.

The height c of the trough leg section 5.3.1 is preferably at the width e of the second groove 8th adapted that when turning back the gutter 5 the compensating band 10 is compressed and thereby a clamping of the second gutter leg 5.3 in the second groove 8th results. By this compression of the equalization band 10 is also advantageously achieved that even with variations in the width d of the second groove 8th a seal over the entire length of the shuttering element 2 is reached. The same applies to occurring swelling and shrinkage movements of the shuttering element 2 ,

Incidentally, the description of the embodiment according to the 7 to 10 also for the embodiment according to 11 ,

The essential difference of the embodiment according to the 11 Compared with the embodiments described above is that the first compensating band 7 not in the first groove 6 is arranged, but in the region of the free end of the first trough leg 5.2 , in particular this free end of the first trough leg 5.2 is arranged across. In particular, the trough points 5 only a first trough leg section 5.2.1 up, from the gutter floor 5.1 sticks out and moves in the direction of the first groove 6 extends. The first compensation band 7 may in turn consist of an elastic material. The arrangement on the gutter 5 This can be done by making the first compensating band 7 a notch 7.1 or having a cut. This can be the first compensation band 7 on the free end of the first trough leg 5.2 be plugged. It is also possible that on the first compensating band 7 a Aufsteckbereich is provided, especially for attachment to the free end of the first gutter leg 5.2 is trained. The first compensation band 7 can have any cross-sections, in particular a round, oval or polygonal cross-section.

That on the first trough leg 5.2 arranged first compensating band 7 becomes when attaching the shuttering element 2 on the support 4 to the shuttering element 2 in the area of the first groove 6 pressed down and the first compensating strap 7 thereby at least partially compressed in the upper area. This ensures that the gutter leg 5.2 and thus the entire gutter 5 clamped between the shuttering element 2 or the first compensating band 7 and the support 4 is fixed. By means of the first compensating band consisting of an elastic, compressible material 7 is also achieved that bumps in the area of the support 4 while maintaining a tight fit of the free end of the first trough leg 5.2 opposite the compensating band 7 can be compensated. As a result, even with existing bumps in the area of the support 4 and when a large amount of liquid flows into the channel 5 a leakage of the liquid over the first trough leg 5.2 effectively avoided.
