Description

Reinforcement with sealing tape

The present invention relates to a reinforcement such as in particular a connection reinforcement for concrete components according to the preamble of claim 1.

In the field of transitions from floor or ceiling slabs to side walls in concrete components, it is essential

be able to absorb sufficiently occurring shear, compressive and tensile stresses. Accordingly, so-called connection reinforcements or reinforcing baskets are arranged in this part, wherein some rods thereof extend into the floor or ceiling panels as well as into the wall. Such connection reinforcements are well known, as described, for example, in EP 0 495 135, CH 642 131, CH 697 760 and CH 700 503, to name only a few.

Especially in the corner of walls to floor or ceiling panels, especially in exterior facades, or generally in joints in walls in a humid environment, the problem of moisture penetration. As a rule, it is proposed, for example, to arrange a seal on an exterior facade or in general in joints in walls, be this by applying a sealant, for example based on bitumen or a polymer compound, or by arranging a sealing membrane along or on the joint in the wall. On the one hand this requires an additional operation and also there is the risk of damage, for example, an external seal, for example, when introducing

Rocks, boulders and the like, to a sinking of the

Allow moisture along, for example, an exterior facade.

The task is to create a simpler and easier way

work-saving solution to avoid the ingress of moisture.

The object is achieved by means of a reinforcement, such as in particular a connection reinforcement according to the wording of claim 1.

Proposed is a reinforcement such as in particular a connection reinforcement for concrete components, in particular for connecting a concrete floor slab or ceiling slab with a wall, or for arranging in or along a joint in a wall, for example. At the transition floor to floor slab, comprising at least one reinforcement, for example. Consisting of Longitudinal and transverse bars and at least one arranged in or on the reinforcement joint seal. In the

Joint seal provided to be arranged at the transition from wall to floor or ceiling slab or along a joint in a wall, for example. At the transition floor to bottom plate, it is a running along the reinforcement geomembrane resp. a sealing plate. In a reinforcement consisting, for example. From longitudinal and

According to one embodiment, transverse bars run the transverse bars at least almost parallel to one another and are designed such that, in particular in the case of the

Connecting wall and floor respectively ceiling plate at least two at least approximately mutually perpendicular sections are formed on the transverse rods, wherein at least one portion is provided to hineininzuragen in the wall of the component and the other portion to be arranged in the bottom plate or a ceiling ,

According to one embodiment, the reinforcement is called a so-called port basket or as a reinforcement mat

formed with transversely extending to the wall transverse bars and along the wall extending longitudinal bars.

According to a off ^'design variant, it is proposed that the sealing web is arranged longitudinally with respect to the basket along that leg of the transverse rods and perpendicularly thereto, which are parallel to the wall and at least partially in this Arranged.

The longitudinal bars of the reinforcing cage are at least almost parallel to each other and arranged extending in the longitudinal direction of the basket. According to a further embodiment, at least a portion of the transverse rods are at least almost U-shaped bent, comprising two legs with crosspiece therebetween, the sealing sheet along each one or the other or both legs and / or directed from the crossbar to the interior of the basket in Longitudinal direction of the basket is arranged to extend.

For arranging the geomembrane but also an auxiliary basket or an assembly aid can be provided which, for example, inserted in a reinforcing cage or a reinforcing mat of the known type or can be placed on this. The advantage of an auxiliary basket is that the joint tape or sealing tape can be arranged flexibly or aligned with the joint according to local conditions. When using, for example, a plurality of reinforcing mats, the auxiliary basket can also be arranged lying between them in the region of a working joint, such that the sealing sheet is arranged to seal the working joint.

The geomembrane can be, for example, a metal sheet, which is optionally arranged on the legs of the transverse rods or on the longitudinal bars, such as welded or introduced by means of auxiliary basket or mounting aid in the reinforcement. The geomembrane can also be a film or a board based on a polymer, such as in particular based on thermoplastic olefins such as soft polyethylene or PVC, rubber, rubber or the like, bitumen-coated fabrics, etc., both reinforced or unreinforced ,

When supplied to a site reinforcing baskets or reinforcing mats, the geomembrane or the joint tape, such as a composite sheet may be pre-assembled, preferably the sheet each laterally projecting from the basket or the mat to overlap when mounting the sheets or the sealing strip guarantee. The high of

Geomembrane or composite sheet is, for example. Up to 10 cm or possibly more.

Figure 1 shows in perspective arranging a

Connection reinforcement 2 according to the invention in the area of the coincidence of a concrete wall on a concrete floor resp. Ceiling plate 1. The connection reinforcement 2 is such formed on the one hand, in particular transverse bars 11 both in the ground resp. Ceiling plate 1 as well as projecting into the wall to occur in this area

Sufficient to absorb thrust, compression and tensile stresses.

In practice, it has been found that, in particular for external facades, the gap 10 when meeting the wall on the floor resp. Ceiling plate 1 with respect to incoming moisture is critical. Therefore, for example, on external facades especially in this area sealing measures are provided, such as on the basis of bitumen or plastic geomembranes are glued. However, the same problem sometimes also exists in the interior of a housing, for example when sealing a light shaft against moisture in the ground.

The invention shown in Figure 1

Rebar basket now has one in the longitudinal direction of the basket

extending sealing sheet 13, which are arranged on the transverse bars of the reinforcement.

Recognizable this geomembrane 13 is also in Figure 2, showing a cross section through the view of Figure 1. Recognizable is a transverse bar 11 of the reinforcing cage 2 comprising two parallel to the wall 3 extending legs 15 and 17, wherein the one leg 15 in the bottom part. 1 is bent, to form a leg portion 19, extending into the bottom plate 1 into it. For the

Holding together the div. Cross bars 11 are further longitudinal bars, e.g. 20 to 24 are provided, which are arranged in the longitudinal direction and parallel to each other. The other

Leg 17 is finally in FIGS. 1 and 2

At one leg 15 extending in the longitudinal direction of the basket, the sealing sheet 13 is arranged, whereby a penetration of moisture through the joint 10 and a working joint between the wall and floor respectively resp. Ceiling plate is prevented. This eliminates the need to arrange a specifically directed to this joint seal, for example, in the area of an external facade, in a moist surface or generally at the risk of moisture penetration through a joint.

In Figure 3, a further arrangement of a

Reinforcement basket 2 according to the invention, again comprising two legs 15 and 17 and a transverse web 25 extending therebetween. Again in the region of the joint 10 between the wall 3 and the base plate 1, the sealing sheet 13 is arranged on the one leg 15 in order to

prevent moisture along this gap 10 can penetrate the wall 3. In the arrangement according to FIG. 3, an additional reinforcement 31 is additionally provided in the base plate, as well as reinforcing bars 33. FIG. 4 shows a further arrangement of a

Reinforcing basket 2 according to the invention, again comprising the two legs 15 and 17 extending in a wall 3 and the leg 17 of a against the bottom resp.

Ceiling plate back bent leg section 18. In the floor resp. Ceiling plate 1 extending further leg portion 19 is provided, and finally

Longitudinal bars 21 and 23 or more to form the basket 2. The ^' inventive geomembrane 13 is now on

bent back leg portion 18, in the region of the joint 10 between the wall 3 and floor resp. Ceiling plate 1.

This serves to arrange the sealing strip 13, transversely to the

Working or transitional joint 10. FIG. 8a shows the region in cross section, while FIG. 8b shows the arrangement of the auxiliary cage 51 in perspective. The advantage of using an auxiliary basket is that the

Sealing tape such as a composite sheet can be positioned exactly in relation to the working joint, since the auxiliary basket 51 is usually within the two legs 15 and 17 freely movable. Similarly, FIGS. 9a and 9b again show the same area between a wall 3 and a base plate 1, wherein instead of the auxiliary cage according to FIGS. 8a and 8b an L-shaped reinforcing auxiliary mat 53

is used, in each case on the upstanding leg of the L-shaped cross bars in turn in the region of the working joint 10, the sealing strip 13 is arranged. FIG. 9a shows the region in cross-section, while in FIG

Placing the L-shaped reinforcement auxiliary mat 53 is shown with the sealing strip 13 in perspective.

In Fig.10, again in the range of wall 3 to bottom plate 1, the use of an L-shaped sealing strip 13 is shown, which is held by means of a bracket-like mounting aid 55, for example. On a leg 17 of the reinforcing basket 2 fitting.
