EP2829657B1 - Dilatation and contraction joints in traffic areas made of concrete - Google Patents

Description

The invention relates to a set for joint construction for trafficable concrete surfaces of concrete slabs, which are produced on site, with Abschlusszargen for the enclosure of adjacent concrete slabs, each having a specific for covering the vertical end faces of the concrete slabs, substantially vertically oriented central leg, the top in a horizontally angled upper end leg and down into a likewise horizontally angled lower Aufstandsschenkel.

The invention comprises navigable traffic areas made of locally produced concrete slabs and in particular a device for bridging and forming dilatation and contraction joints in order to dissipate the resulting stresses by thermal deformation in the concrete covering and thereby avoid damage such as cracks and flaking. The peculiarity consists of the multifunction of relatively thin closing frames that encircle the concrete slabs.

Such joints constructions are required for trafficable concrete pavement surfaces, for example, roads, airfields, aprons, terraces, roofs and especially for parking decks on roofs. Since the traffic areas are exposed to the weather, in particular extreme temperatures of + 60 ° C to -30 ° C especially on the surfaces in summer and in winter, measures must be taken to compensate thermally induced changes in length. In particular, when the concrete slabs are made on thermally insulated and sealed roof surfaces, they must be able to expand and contract independently without transferring stress to the underlying seal. For this purpose, between the concrete slabs circumferentially arranged dilatation and Contraction joints provided. These joint chambers must be closed elastically, so that no sand, dirt, water or snow can penetrate, which could hinder a tension-free deformation of the concrete slabs and can lead to cracks and flaking. It is therefore necessary to permanently and safely close these joint chambers with an elastic material.

From the EP 1 911 882 is an existing concrete slabs traffic area with a joint construction of the type mentioned above, in which in the joint chamber an elastic sealing strip is introduced as a hollow chamber profile, which is placed on both sides of the frame legs. Under extreme weather conditions and under the loads and deformations caused by moving vehicles, the sealing tape in the known device can become loose and fall into the joint chamber or even be pulled out by rolling friction of the overlying vehicles, so that sand, dirt and other undesirable materials in can penetrate the expansion joint. Another weakness of this construction is that the joint through the end legs, the joint chamber of the lower part of the frame is too narrow to accept the deformations of larger concrete slabs risklos, which can lead to damage to the road surface.

At one of the DE 20 2012 102 396 U1 known construction, the sealing of an expansion joint between concrete slabs by means of elastic grout or rubber granules is made. In the course of time, embrittlement, demolition and erosion of the material occur with the result that undesirable materials can penetrate the expansion joint again. In addition, such a joint connection is very maintenance-intensive, which can lead to damage to the underlying seal.

Other joint constructions between adjacent concrete slabs are from the DE 1 658 845 A1 as well as the DE 20 2006 015 909 U1 known.

Object of the present invention is to improve a joint construction of the type mentioned above for drivable traffic areas made of concrete slabs, so that at low cost production a long service life is guaranteed and as possible no maintenance costs.

The solution according to the invention is that the closing frames are provided in the upper region of the central leg near the drivable surface of the concrete slab, each with a horizontal, lateral claw groove, the open sides of the claw grooves of adjacent concrete slabs opposite to each other at the distance of the joint width provided between the concrete slabs joint chamber , and that the joint chamber is covered by an expansion joint profile seal in the form of a hollow chamber profile made of elastic material substantially flush with the drivable surface of the upper end leg of the concrete slabs, wherein the expansion joint profile seal projects down into the region of the claw grooves and laterally projecting anchoring lips which in engage the claw grooves. As a result, it is permanently secured in their position.

The claw grooves according to the invention are formed in a simple and cost-effective manner in the Abschlusszargen. The expansion joint profile gasket is produced as an extruded profile in a simple manner and inexpensively as an endless strand and prefabricated for the object-specific use in the factory to the concrete slab size and delivered to the site.

In the production of driveable traffic area concrete slabs on site, the expansion joint profile seal is pressed in a simple manner from above into the joint chambers, wherein the hollow chamber profile reducing the width of the profile sealing strand by lateral Squeezing allows, so that the laterally projecting anchoring lips are first pressed together so far that they fit into the narrow joint chamber inside to expand laterally when reaching the claw grooves laterally into the claw grooves and dig. This creates a positive connection between the expansion joint profile seal and the opposite Endzargen, because the lateral Klauennuten form an undercut. In this way, the expansion joint profile seal is completely securely anchored in the claw grooves of the Abschlusszargen within the joint chamber and it remains even under extreme stress by moving vehicles or by different weather conditions.

This joint construction can now work as a dilatation and contraction joint, that is, the joint chamber can be narrower or wider, without the expansion joint profile seal is too loosened or excessively squeezed, because the hollow chamber profile allows large strains and compressions and always remains safe through the lateral anchoring lips anchored in the claw grooves. The invention therefore ensures that no dirt, sand or other debris can penetrate into the joint chambers and cause damage there, for example by filling the joint chamber with material which restricts or prevents the expansion of the concrete slabs and would then lead to deformations and damage to the concrete slabs , The introduction of the expansion joint profile gasket requires no complex means or steps and can therefore be carried out very inexpensively.

In an embodiment of the invention, the claw grooves in profile on a substantially horizontally oriented upper leg, an obliquely downwardly sloping leg and a vertical leg. This gives an arrow-shaped profile of Expansion joint profile seal. It is therefore possible to push the "tip of the arrow" into the joint chamber, the oblique side surfaces of the expansion joint profile seal sliding downwards along the upper edges of the joint chamber into the joint chamber and in this way being squeezed together. To introduce the expansion joint profile seal in the joint chamber thus requires only a small force. The expansion joint profile seal is compressed laterally so that it can be inserted into the joint chamber.

The lower sloping leg is adapted to the sloping surface of the lateral anchoring lip of the expansion joint profile seal, so that the anchoring lips can slide unhindered into the claw grooves and dig into it. The upper leg of the claw grooves, however, is aligned horizontally, so even with strong upward forces on the expansion joint profile seal no force components that compress the expansion joint profile seal and could affect their solid anchorage in the claw groove.

In a preferred embodiment, the Abschlusszargen made of chrome-nickel steel or plastics. This measure protects them against corrosion in the long term. In addition, these materials facilitate the shaping of the Abschlusszargen, in particular the formation of the claw groove according to the invention.

If the free edge areas of the upper end legs of the Abschlusszargen are angled downwards, you will get a total of more stable Abschlusszargen. However, there is then the danger that when pouring the concrete slab air bubbles are trapped in the upper end leg, which could affect the stability and resilience of the edging profile. It Therefore, ventilation holes are introduced into the upper end legs, from which air which has entered during the introduction of the concrete and the mechanical compression can escape.

By the measure that the free edge areas of the lower Aufstandsschenkel the Abschlusszargen are angled upwards, the stability of the Abschlusszarge is also improved.

An important part of the invention is that a concrete stop film is attached to the undersides of the lower horizontal uprising legs of the Abschlusszargen, which insulates emerging cavities on uneven roof surfaces and Lunken so that the liquid concrete can indeed flow into the cavities below the treads, but not in the expansion joint chamber to be kept clear. The concrete stop film is preferably glued to the lower tread leg of the Abschlusszarge

A further advantageous embodiment of the invention provides that Zargeneckstücke are arranged at the corners of the rectangular or square concrete slabs, which are formed by Abschlusszargen by miter cuts and notches. Except for the latter features, these Zargeneckstücke do not differ from Abschlusszargen, which has bent at right angles. The Zargeneckstücke thus consist of a bent at right angles modified central leg and miter cuts each divided into two sections Abschlussschekel and Aufstandsschenkel, each meeting at right angles. In other features, the Zargeneckstücke are designed as well as the Abschlusszargen.

To seal the crossing areas of the joint chambers, in which four corner pieces meet, becomes a cross-shaped Central molding proposed, which corresponds in shape and function of the expansion joint profile seal.

Preferably, the four ends of the central moldings are glued to the adjacent expansion joint gaskets.

The stability of the connection can be further improved by the central molding is provided at its ends with pins, which serve to connect the central molding with adjacent sealing gasket profile gaskets.

The invention also includes a configured according to the features described above, consisting of two such Abschlusszargen Zargenbauteil for a trafficable traffic area made of concrete, because the core of the invention manifests itself in the design of Zargenbauteile, especially in the Klauennuten.

The Zargenbauteil invention is characterized by the fact that two Abschlusszargen are initially connected as an assembly aid by means of plastic screws preferably made of polyamide firmly together, so that their central leg and the claw grooves are opposite, with inserted spacers guarantee the exact distance of the joint chamber.

The closing frames are thus connected together in a position that they later occupy in the trafficable traffic area, whereby they can be installed in the planned plate and joint grid assembly stable. The Zargenbauteile be placed on site at the appropriate place and connected to each other. For the connection between two Zargenbauteilen suitable butt connectors are provided which provide a simple connection by snapping two Allow frame lengths. Only unevenness of the footprint must be compensated by underlying wedges.

Preferably, the spacers consist of metal profiles. These are easy to produce with the required cross-section and to procure cost-effective. The spacers can also be made of plastic.

The invention also includes prefabricated central crossing components, in which four Zargeneckstücke are connected to each other, so that their central leg and the Klauennuten face each other, with inserted spacers guarantee the distance of the joint chambers. The central crossing components are delivered pre-assembled to the construction site and placed on the floor according to the dimensions of the concrete slabs to be cast. The straight sides between the central crossing components are then filled with frame members which are adapted in length to the dimensions of the concrete slab, whereby concrete concrete frames are produced with liquid concrete.

After setting up the central intersection and Zargenbauteile invention and their connection to the respective complete frame, the resulting formwork are poured with liquid concrete, making sure that no concrete gets into the joint chambers. After setting the concrete, the spacers and the plastic screws can be pulled out of the joint chambers or cut out so that the joint chambers are then completely free of material which could impair their purpose. Finally, the expansion joint profile seal is pressed from above into the joint chamber until it engages and is securely anchored.

The invention also includes a central molding, which corresponds in shape and function of the expansion joint profile seal. It is designed to accommodate the same deformation as the expansion joint profile seal. The central molding is formed cross-shaped with four equal-length legs, the legs ensure a positive connection to adjacent expansion joints profile seals. In addition, two stable pins were arranged at each of the four ends of the central molding, on which later the expansion joint profile seal can be pushed. Next, the blunt sides of the joint connection are each coated with a special adhesive, so that after attaching the expansion joint profile seal a firm and permanent connection between the molding and profile seal by means of plug connection and bonding is formed.

Already during the factory pre-assembly of the central crossing components, the central moldings are mounted in their intersection areas. Then the frames are placed on the insulation and sealing structure as well as the separating and sliding bearing located thereon and introduced the concrete, so that individual concrete deck plates arise. After curing of the concrete, the device for receiving the dilatation and contraction movements of the road surface is completely formed.

After pouring the o.g. Frame with liquid concrete and solidification of the concrete, the joint chambers are sealed with expansion joint gaskets and connected the four ends of the central moldings with the adjacent strain profile gaskets.

In FIG. 1 can be seen a section of a partially finished trafficable traffic surface concrete slabs 1, 2, 3 which are limited at their narrow sides 4, 5 with end frames 6, 7.

How to best in the FIGS. 2 to 4 recognizes the Abschlusszargen 6, 7 each consist of a central leg 8, at the top of a horizontally angled upper end leg 9 and below a likewise horizontally angled lower tread leg 10th followed. The central leg 8 of the Abschlusszargen 6, 7 have in the upper region 11 each have a claw groove 12, which consist of a horizontally oriented upper leg 13, a lower oblique leg 14 and a vertical leg 15. The oblique leg 14 rises from the open side of the claw groove 12, starting at the vertical leg 15 towards. Free edge regions 16 of the upper end legs 9 of the end frames 6, 7 are angled downwards and the non-angled portion of the upper end legs 9 is provided with vent holes 26. Free edge regions 17 of the lower turf legs 10 of the end frames 6, 7 are angled upwards and on the undersides of the non-angled portions of the lower turf legs 10 each have a concrete stop sheet 18 is attached, preferably by gluing. The concrete stop sheet 18 is guided loop-shaped, so that their free edge protrudes from the respective end frame 6, 7 in the horizontal direction.

The Abschlusszargen 6, 7 are bent from chromium-nickel steel sheet, wherein the claw grooves 12 are formed. Between the Abschlusszargen 6, 7 of the concrete slabs 1, 2 is in each case a joint chamber 19, which extends over the entire side length 20 of each concrete slab 1, 2, 3 and even about 10 to 20 mm, in special cases to 40 mm wide. In the finished traffic area, the joint chambers 19 are each covered with a expansion joint profile seal 21 upwards and the joint chamber 19 is closed, the expansion joint profile seal 21 with the surface 22 of the concrete slabs 1, 2, 3 flush.

The expansion joint profile seal 21 is made of an elastic material, preferably EPDM and has the shape of a hollow chamber profile. These hollow chambers 23 allow compression of the expansion joint profile seal 21. The expansion joint profile seal 21st also has in profile two laterally projecting anchoring lips 24 which engage with mounted expansion joint profile seal 21 in the claw grooves 12 and are firmly anchored there by positive locking. In addition, the expansion joint profile seal 21 is designed arrow-shaped in section. Therefore, when pressed into the joint chamber 19, its tip 25 compresses the anchoring lips 24 so that they can slide through the narrow joint chamber 19 until they reach the claw grooves 12, into which they snap laterally when the expansion joint gasket 21 relaxes again. Thereafter, the arrow-shaped beveled bottom of the expansion joint profile seal 21 nestles against the obliquely oriented oblique leg 14 of the claw groove 12, while the horizontally oriented upper leg 13 of the claw groove 12 prevents slipping out of the lateral anchoring lips 24 of the expansion joint profile seal 21 from the claw groove 12.

That in the Figures 3 and 4 shown Zargenbauteil 27 consists of two Abschlusszargen 6, 7, which by means of a spacer 28 (FIG. FIG. 4 ) are kept at a distance from each other and are connected to each other by means of plastic screws 29 as mounting aids. The spacer 28 consists of a metal profile whose thickness corresponds exactly to the width 46 of the joint chamber 19.

The frame components 27 according to the invention are set up on site and connected to one another by means of butt joints 30. The butt connectors 30 are also made of chromium-nickel steel sheet, which follows in profile the form of the Endzargen 6, 7 with central leg 8, upper end leg 9 and lower tread leg 10, wherein the modified upper connecting leg 31 and the modified lower connecting leg 32 of the butt connector 30th each have no angled wall area. The connection between two on the same side of a joint chamber 19 abutting End frames is done in a simple manner by clipping a butt connector 30th

To facilitate the production of concrete slabs on site serve prefabricated central crossing components 40, in which four Zargeneckstücke 36 are interconnected.

How to best in FIG. 5 detects the Zargeneckstücke 36 consist of a bent at right angles modified central leg 41 and by miter cuts each divided into two sections tail legs 42, 43 and tread pieces 44, 45, which meet each at right angles. Otherwise, the Zargeneckstücke 36 are designed as well as the Abschlusszargen 6, 7. In the central crossing components 40, the Zargeneckstücke 36 are arranged so that their central leg 41 and the claw grooves 12 are opposite, being held by inserted spacers 28 at a distance of a joint chamber width 46.

To seal the joint chambers 19 in the corner areas, in each of which four Zargeneckstücke 36 meet, serves in the Figures 5 and 6 shown central mold part 37, which corresponds in shape and function of the expansion joint profile seal 23. It consists of four cruciform arranged in each case the same length legs 38, the ends 39 are bonded to the adjacent expansion joint gaskets 23. In order to increase the strength of the connection, the ends 39 of the central molding 37 are provided with pins 34 which are inserted into corresponding hollow chambers of the adjacent gasket groove seals 21.

The central crossing components 40 are connected to the central moldings 37 as shown in FIG FIG. 5 delivered pre-assembled to the construction site and according to the dimensions of the to be poured Concrete slabs 1, 2, 3 placed on the substructure 33 and the separating and sliding layer.

When constructing the construction, the central crossing components 40 are first positioned in the corner points of the traffic area to be produced, and the straight intermediate areas between the central crossing components 40 are filled with frame components 27 as centerpieces. Depending on the length of the filled with the frame members 27 routes the size of the concrete slabs to be produced can be varied. In this case, the frame frames that pour with liquid concrete form as formwork for the concrete slabs 1, 2, 3.

At the same time serve the Zargenbauteile invention 27 and central crossing components 40 as a teaching for the concrete coverings, because they not only determine the width 46 of the joint chambers 19, but also provide an upper guide and fixed point for the concrete coverings. In addition, so the necessary compression energy can be passed into the introduced concrete. The inventive arrangement of Zargenbauteile 27 and central crossing components 40 allows processing of the concrete surface with rotating rollers, Rüttelbohlen and large dish washers. The lower Aufstandsschenkel 10 of the Abschlusszargen 6, 7 take over the function of a footprint, which can be placed on the substructure 33 and aligned. Any existing unevenness of the substructure 33 can be bridged by wedge documents.

When pouring the liquid concrete, the concrete stop sheet 18 prevents the concrete from penetrating into the expansion joint chamber 19. Existing air can escape through the vent holes 26 in the upper end legs 9 of the end frames 6, 7, so that the between the central leg 8 and angled wall portion 16 formed cavity can completely fill with concrete.

After filling the liquid concrete hardens this. When the concrete has reached sufficient strength, the plastic screws 29 are cut from polyamide and removed from the joint chambers 19, so that the expansion joints for dilatation and contraction of the concrete slabs 1, 2, 3 are available. The invention ensures that the joint chambers 19 close exactly and evenly with the drivable surface 22, so that there is an overall aesthetic appearance.

By prefabrication of Abschlusszargen 6, 7 to the Zargenbauteilen invention 27 and central crossing components 40, the required for the pouring and processing of the concrete stability and strength is ensured and the width 46 of the joint chambers 19 is precisely defined.

The invention enables the easy and safe closing of dilatation and contraction joints, which serve between the concrete slabs to avoid mechanical stresses due to thermal deformation of the concrete slabs. In this way, cracks or chips on the concrete slabs are avoided. On the one hand, they have the function of a shuttering when introducing the liquid concrete and on the other they provide the claw groove 12 according to the invention for the anchoring of the expansion joint profile seals 21 and 37 of the central molding. The Abschlusszargen 6, 7 can be made inexpensively and easily from relatively thin material. The claw grooves 12 are formed.

When making traffic surfaces of concrete slabs the Abschlusszargen 6, 7 serve not only as concrete formwork, but also as a teaching for the concrete coverings by their visible tops are aligned both horizontally and vertically in a line, the upper guide and fixed points for casting forms the concrete coverings. This ensures a flat concrete surface even beyond the boundaries of the individual concrete slabs. In addition, the joint constructions according to the invention using the end frames 6, 7 ensure that the necessary compaction energy can be introduced into the concrete by machining the concrete surfaces with rotating rolls, shaking planks and large dish washers. The lower tread legs 10 of the end frames 6, 7 are based on the substructure 33, wherein any unevenness of the substructure 33 are compensated by means of wedge pads. In this way, the joint chambers 19 are absolutely uniform, both in terms of the joint chamber width 46 and the other with respect to exactly aligned on the horizontal upper edge regions, which not only aesthetically pleasing appearance of the traffic area, but also a simple and secure insertion and anchoring of the expansion joint gaskets 21st and the central moldings 37 is ensured.

By pre-fabricating the Zargenbauteile 27 and Zargeneckstücke 36 by means of spacers 28 and plastic screws 29 not only the exact joint width 46 is fixed, but also saves operations on site in the production of traffic areas. The production can therefore be done locally with simple means and relatively quickly. Initially, the points of the traffic area to be created are determined, at which the central intersection components 40 are to be positioned. Thereafter, the gaps between the central crossing members 40 become straight Zargenbauteilen 27 filled, which are connected to each other and with the central crossing components 40 by butt connector 30 by the butt connectors 30 are simply locked. Subsequently, any bumps are compensated by inserting wedge pads. In this way one obtains for each concrete slab to be cast a frame which forms a solid unit so that all the dynamic requirements imposed on the frame during the casting of the liquid concrete and its compaction or further processing can be fulfilled. After the concrete has reached a sufficient strength, the plastic screws 29 are severed, so that the joint chamber 19 is free and for dilatation or contraction movements of the concrete slabs 1, 2, 3 is available.

Finally, the joint chambers 19 are sealed by inserting expansion joint gaskets 21 against the ingress of dirt or sand or other materials that could prevent the dilatation or contraction of the concrete slabs 1, 2, 3. The expansion joint profile seals 21 are simply pressed from above into the joint chambers 19 until the lateral anchoring lips 24 engage in the claw grooves 12 and anchor the respective hollow chamber seal securely and firmly.

Subsequently, the Abschlusszargen 6, 7 continue to ensure that the joints of the traffic areas have an exact string accuracy and meet high aesthetic requirements, the joints transitions are very flat. The concrete slab dimensions can be done individually, taking into account the desired markings of the parking spaces.
