Description

Herbert Ender, Murnau / Obb. Expansion joint profile

The invention relates to an elongation of the filament several hollow chambers formed by dividing webs, which can be glued to the joint reveals with its lateral outer walls

It is such a sum of impressions in existing building joints of certain rubber-coated Faltprofildiohtungsstrang known, which has at least one provided for receiving the adhesive profile chamber on that side of the Profiles, with which the strand is introduced into the joint, has exit points for the adhesive masses, which are due to the deformation of the profile when the strand is pressed in open and wherein the side parts form a rope shape with one another before the rope is pressed into the puge, which tapers in the direction of the exit points in order to prevent the adhesive material from penetrating when exiting the profile chamber to facilitate between the side part and the reveal

In this belcanned folding profile sealing strip accordingly, the pressing out of the sealant in a direction substantially parallel to the joint reveals on the

M2955022.7.71

Top of the joint opposite inner web bridging, which for this purpose was weakened or completely separated in order to allow the escape of adhesive. For this Basically, however, the transverse webs could not or only partially perform their expansion function was squeezed out of the profile, has proven to be useful in many cases and a reliable seal the joints were guaranteed, difficulties arose in certain cases both with the laying and with regard to gluing, especially in wider structural joints.

The invention is therefore based on the object, in a further development of such a device equipped with ... glue Folded profile, in which hollow chambers divided by webs are formed, the formation to meet in such a way that gluing takes place with certainty when inserting by squeezing the adhesive in the correct position, the elasticity, i.e. the expansion force inherent in the profile is not impaired in any way.

According to the invention, this object is achieved in an expansion joint profile strand of the type mentioned in that a rope of the hollow chambers adjacent to the side walls is filled with an adhesive that can be pressed through openings in the outer wall of the profile between this and the joint reveal.

This ensures that the sieve mortar is not pushed in front of the profile, as was the case with the known design of the Sail, and that the two joint walls are rigid

Ties together, but the adhesive mortar is rather pressed from both the Fugenleibungen adjacent hollow chambers against the joint walls and causes a bonding of Fugenleibungen with the profile on both sides "ao that the profile of the thermal motion can follow occur without any leakage. The adhesive therefore does not form an uninterrupted bridge and therefore no permanently elastic adhesives need to be used for the invention, and the method offers both the advantage of simple and secure installation even with large joint cross-sections.

According to a preferred embodiment of the invention, the adhesive chambers are in the middle section on both side walls arranged so that the escaping adhesive both in this central section and in the above or below lying section for a bond can be effective.

In general, it is not necessary to fill all the chambers of the hollow profile with adhesive mortar when inserting is squeezed out, because then an essential rope of the adhesive mortar would remain within the profile and uselessly would be lost. It has also been shown, in particular, that it is not necessary to replace the adhesive chambers, which are arranged on both side walls in the middle section, to be filled with adhesive over the entire width of the profile. Rather, it is sufficient to arrange an amount of adhesive that is sufficient for full-surface bonding on the outsides to effect, with only a relatively thin adhesive layer between the surfaces to be bonded must be present. in the However, for the purpose of a favorable squeezing out and distribution of the adhesive mortar, it is not expedient to only partially use the chambers to be filled with glue.

/ VU? ^# Ij ^:::

According to a "preferred embodiment of the invention is therefore between the two essentially completely filled adhesive chambers A cavity free of adhesive is provided on both sides of the profile. Instead of this one cavity Of course, several single caramers can also be provided. It is also possible to open the adhesive chambers from the inside supported by a latticework of longitudinal and / or transverse webs that delimit further hollow chambers "

This makes it possible to squeeze the largest percentage of the adhesive out of the adhesive chambers when the sealing strip is inserted into the expansion joint, so that the adhesive is almost completely utilized. This also ensures that between the chambers filled with the adhesive or the hardening adhesive mortar on both sides there is a sufficiently wide room for movement for the gap between the joints and the compression of the profile when the joints are narrowed .

So that the adhesive does not harden during transport and storage within the hollow chamber that houses it, Care must be taken to ensure that the outlet openings or outlet slots are used for transport and storage are covered airtight for the adhesive. For this purpose, the adhesive outlet openings can be on the side walls be closed with a tearable tape.

According to a preferred embodiment of the invention, however, a plastic tape is provided to cover the openings to form on the outer wall of the profile, for this purpose the plastic tape can be welded or welded to the side walls of the sealing profile at both edges

According to a preferred embodiment of the invention however, this masking tape is provided. during the profile production with to be molded and the others The tape to be welded on afterwards. In order to "conveniently tear off when inserting the sealing strip into the expansion joint It is useful to ensure that the tape is equipped with predetermined breaking lines on the beach, which make it easier to pull it off.

According to a preferred embodiment of the invention, 1st part of the hollow chambers of the profile designed trapezoidal, wherein the trapezoidal chambers from an inner verti cal central web, two parallel, diagonally from the center outwardly and upwardly extending ridges and a top of the outer re-wall-forming web are limited , which is inclined in such a way that it intersects the profile strand center plane in its extension downwards

This design ensures that when the profile is pressed together in the upper section by hand or by means of a suitable tool, a corresponding reduction in the width of the lower section is effected _e whereby this reduction in width in the lower section can be greater than that in the upper section, which results in that the sealing strip can easily be inserted into narrow joints.

It is preferably these trapezoidal hollow chambers that are filled with the adhesive mortar, and it is then in particular in a favorable way ensures that when the profile tape is inserted into the expansion joint, the adhesive mortar is squeezed out and is distributed over a wide area of the walls, so that full-surface bonding is guaranteed. If in The moment when Jes mortar is squeezed out, i.e. when it is laid of the lye tape, the adhesive outlet openings tight and

, ill Il I · '· ·· ··

.1111 ·· ·· ··

would be pressed under high tension on the joint pipes, then such a full-surface system or «, gluing cannot be guaranteed.

Instead or in addition, the trapezoidal chambers can also be arranged in the middle section of the profile and / or one above the other ₀

According to a further expedient embodiment of the invention, the expansion joint profile is included in a manner known per se equipped with a vertical central bar. This promotes the deformation described, which is a slight one Insertion into the expansion joint guaranteed, ie. it becomes the width deformation or width reduction in the lower one Section of the profile favors when a squeezing force is applied to the upper section of the profile to reduce the width is exercised.

With such a profile, especially if the- ■ sen dimensions are relatively wide, difficulties in terms of transport arise. Since such profile strands usually have a relatively high section modulus in any direction perpendicular to their axis only supplied in rod form and accordingly in relatively short lengths. For installation in expansion joints, however, is the use longer profiles, especially those extending over the entire joint length, are desirable in order to avoid sealing problems on the To avoid joints from the outset "In order to now According to the invention, it can be transported in greater lengths, according to the further embodiment of the invention provided that the vertical center "web of the profile is executed divided and the so formed partial center webs

ij connected by a hinge at the lower end. Through this there is the possibility that the profile in the stretched

Λ3Ι

th state is wound because in the stretched state the section modulus in the direction of the width dimension is significantly reduced, so that such a tape can be wound in relatively great lengths without the risk of distortion or permanent deformation.

The production takes place preferably in the stretched state, i.e. the extrusion takes place with one on top of the other Teilkanmerprofilen in Aufwickel! State, where then "when inserting the profile into the expansion joint of the frofiling strand lengthways of the hinge band is folded up, the hinge band resulting in an additional spreading force.

According to a further embodiment of the invention, it is provided that the chambers of the Profi1-strand * which house the adhesive are open to the outside, i.e. towards the joint reveals to shape, i.e. to interrupt the side walls at the level of these chambers. It is provided in these to insert a tube profile made of thinner plastic, which is filled with the adhesive mortar is. These profile hoses can then be equipped with a tear-off tape which, when the strand is inserted into the expansion joint, puts the adhesive in the right place and in the the correct amount can escape.

The trapezoidal hollow chamber profiles that contain the adhesive are applied to the joint reveal after insertion of the sealing profile strand, dovetail-shaped recesses «In these: the adhesive is pressed when it is inserted into the Expansion joint. The adhesive is also distributed in the longitudinal direction and in the joint wall leveled out unavoidable bumps; those in profile

Dovetail-shaped recess results after the inflow of the Adhesive form-fitting anchoring of the profile on the joint wall

If the distance between the Eugen walls is greater, the pressure on the hollow chambers filled with adhesive or adhesive mortar is expediently increased by inserting a foamed elastic band, ζ.B ₀ made of polyurethane.
