Abstract

The method is for making concrete wall panels (10) with a casing (102) of noise absorbing material such as porous cement with a profiled surface. The concrete is cast into a mould (28) for the panel and the porous cement is then applied to the concrete. The profiling (104) is then applied to the cement.

Description

I. Field of application

The invention relates to a method and an apparatus for producing a multilayer concrete slab with a profiled surface, such as Noise barriers or the like.

II. Technical background

In the known noise barriers, a concrete slab takes over the load-bearing Function. Moreover, in these noise barriers then on the load-bearing Concrete slab a layer of cellular concrete, such. B. from expanded slate, wood concrete, Foamed glass or expanded clay concrete or the like applied to the Reduction of the sound reflection is additionally provided with ribs.

These known noise barriers are usually in the negative process produced.

In this negative process in the precast plant on the production table the desired wall element size designed with the required rib structure.

These rib structures are usually in a separately created original form pre-cast of elastic plastic (eg polyurethane). One speaks then from structural matrices.

After previously on the production table, the Abstellrahmen as formwork of then the textured die is placed on top of it laid underfloor glued and adjusted by means of a special adhesive. This is necessary so that when stripping the next day the Strukturmatrize not stuck to the finished concrete element, but on the production table remains lying.

Once this preparatory work has been completed, it can be used on the production table with the Production to be started. First the structure matrix is cleaned and with a sprayer with a special release agent wetted to a non-stick To ensure stripping after hardening.

After a certain ventilation time then becomes an aerated concrete mixture introduced and then by means of a puller to the required Discharge height deducted.

Thereafter, by means of a person's muscular strength, a vibrating rammer is guided over the surface to be compacted by lifting and lowering the device. In the individual lifting and lowering files, 0.07 to 0.08 m ^{2 of} surface area are compressed per cycle.

If the plate has been stamped off, the required material height is checked, if necessary corrected and re-compressed once again.

After that, the actual concreting process of the load-bearing wall panel kick off. The reinforcement is inserted and the mold filled with concrete, compacted and subtracted.

Later, the concrete is reworked (e.g., smoothed) to make the to achieve the desired surface.

The production of one-sided profiled wall elements is thus very time consuming and also very expensive.

III. Presentation of the invention a) Technical task

It is therefore the object of the invention, a method and a Device with the wall panels made of concrete with at least one profiled header shell can be quickly manufactured easily and inexpensively can.

b) Solution of the task

This object is solved by features of claims 1, 2 and 8. advantageous Embodiments emerge from the respective subclaims.

Through the work sequence, first the load-bearing wall panel made of solid concrete and then apply the sound-absorbing material on the outside and to profile on the outside is not a textured die in the Total size of the wall plate needed and therefore the corresponding costs saved, and also the associated replacement problem no longer occurs.

In that the wall plate form lies horizontally in its main plane and upwards, So with one of the large-area pages, open, is the filling, distributing and Compaction of the material as well as the lateral support of the formwork unproblematic and fast possible, especially if the sound-absorbing Material such as the cellular concrete a curable and before curing pourable or flowable material.

In the following, only "aerated concrete" will be briefly mentioned, without this Sound-absorbing material to limit this.

The same applies in advance for the introduction of solid concrete and for the Reinforcement necessary incorporation of reinforcement of structural steel into the mold, which is also easily possible because of the large opening.

By applying and processing the sound-absorbing aerated concrete on the solid concrete before it hardens and in particular immediately after Inserting and compacting the solid concrete, no time is lost to Layer by layer to allow the material to harden.

By profiling the outside of the sound-absorbing material by means of Pounding is simultaneously carried out on the one hand by e.g. Aerated concrete in the transverse direction to Main level sufficiently compacted and on the other hand, an intimate, positive Connection between the cellular concrete and the not yet cured Solid concrete reaches, whereby a firm connection of the two layers without additional measures is achieved.

By the profiling first coarsely preformed and then in their final Form is completed, is the degree of deformation at each step relatively low, so this procedure even at a bad only flowable material such as cellular concrete is feasible.

The preforming by transverse to the main plane protruding pairs of Preform elements, in particular knife edges, which subsequently in the Main plane to be moved to make the recesses of the profiling, So for example, the grooves of the profiling, the force required for the Profiling much lower than by dipping a negative profiling into the outside of the aerated concrete. Above all, it would be pure immersion only bring the desired success if the material is flowable enough would be up to the top by crowding and flowing along the flanks Buckling of the profiling to bulge and form, resulting in the flowability of As a rule, sound-absorbing materials used here no longer exist is possible. To come as close as possible to the final profile form, the Vorformen already the height of the resulting ribs by a stop limited. Then immerse in the preformed grooves to the final Profiling a rib rammer, whose stamp face the negative mold for desired final profile shape of the outside of the attachment shell has.

The final profiling by means of Rippenstampfers is preferably carried out in itself in two stages, by first only the elevations of the Rippenstampfers in immerse the preformed grooves, causing the material to continue in between the ribs of the profiling is pushed up. In this position, the persist Elevations of the Rippenstampfers and the floors between the elevations are then placed on the upper ends of the ribs of the profile of the Wall plate pressed on.

• einerseits erfolgt eine Verdichtung in Richtung der Hauptebene durch die sich hin und her bewegenden Messerkanten,
• andererseits erfolgt eine Verdichtung quer zur Hauptebene der Wandplatte durch das vertikale Aufsetzen sowohl der Stempelplatte des Vorformers als auch des Rippenstampfers auf die Oberfläche der Vorsatzschale.

A significant advantage of the preforming by the knife edges moving back and forth in the main plane is also that the uniform compaction of the material of the facing shell, which is important for the quality of the facing shell, is achieved very well by the two-stage densification:

• on the one hand, compression takes place in the direction of the main plane through the knife edges moving back and forth,
• On the other hand, a compaction takes place transversely to the main plane of the wall plate by the vertical placement of both the stamp plate of the preformer and the Rippenstampfers on the surface of the facing shell.

This is a directed in only one of the two directions structure of Aerated concrete largely avoided.

This procedure is carried out in each case for a partial area of the wall panel, which comprises a plurality of grooves or ribs, but divided into Sections on the total length of the plate.

A section extending over the entire length of a rib will be included not edited at once, but in turn subdivided into subsections that one after the other, each subsection in turn finally profiled by means of the preformer and then by means of Rippenstampfers becomes.

For profiles, not just an extension direction, but for example may have two intersecting extension directions, the Processing optionally progressing in both directions of extension of Profiling be continued, in only one extension direction is this preferably at the same time the direction of progress.

The successively processed subsections or sections overlap each slightly in the direction of progress, in the direction transverse to Course of profiling around a profile.

The approach of the next working position, ie the change of one to the next subsection or section to be processed preferably automatically effected by the control of the machine. At the beginning and end of a section, ie the direction of the profiles, can before all of the Rippenstampfer with its final profile shape over the Project outside dimensions of the wall plate form and in there along the Outside edge of the mold extending profiles, usually mounted in the form of Sheet metal combs, immerse, which by exact fit an exact positioning of the Allow work unit.

The positioning when changing from one subsection to the next in Course of the profiling is less problematic, as long as doing so Overall, an overlap of the individual subsections is achieved.

Preformer and Rippenstampfer are preferably along along the working surface and thus the wall plate design moves and each subsection is immediately after each other first by the preformer and then processed by Rippenstampfer, preferably through only one time immersion or placement on the attachment shell.

Accordingly, wall panels that are on both sides with a Front shell made of sound-absorbing material with profiled surface be prepared in two ways:

Either first, as described above, a load-bearing wall panel Solid concrete and applied to it and profiled an attachment shell sound-absorbing material. After curing the two Layers, this plate is removed from the mold, turned 180 ° and with the already finished attachment shell down again in the form filed so that on the now accessible second outside of the Solid concrete slab again a layer of sound-absorbing material applied, compacted and profiled.

If you want to avoid the time required for curing between, so in the Wandplattenform first a whole area a Strukturmatrize inserted, which the Negative form of profiling of the facing shell has. Then you can then layer by layer, the first facing shell, the wall plate Solid concrete and then the second facing shell in a row and without Curing time applied in between and the latter last profiled.

This procedure is time-saving and cost-effective with the help of a Machine, in which over a work table, by means of a peripheral edge has a function as a wall plate shape, about a support frame on a Processing unit is arranged, in particular a preformer and a Finishing rammer, which are moved at least in the vertical direction can.

After the introduction, compression and removal of the solid concrete is the sound-absorbing material applied and evenly distributed and then compacted by means of the preformer and then the Rippenstampfers and profiled.

The flat, horizontal manufacturing table is the wall plate shape by on the production table - according to the desired dimensions of the Wall plate - soaring upwards around the top, that is to say with the mostly quadrangular ones Wall panels four in a square to each other, adjoining, Bounding ledges project upwards, their height as a puller can serve and thus determine the thickness of the wall plate.

In which the processing plant one hanging above the production table and down to the production table lowerable, each stamp-shaped preformers and Rippenstampfer includes, with the help of these two working elements the Surface of the wall plate to be processed in sections, by first the preformer and then the Rippenstampfer preferably on and the same partial area, ie a section or subsection of the upper side, acts.

For this purpose, preformers and rip rammers are attached to one or the other suspended from a common intermediate frame, opposite which they by means of a vertical drive can be lowered while the intermediate frame in the Horizontal relative to the production table is movable so that this Working elements can reach any area of the work table.

Since preformers and rammers side by side, especially in the direction of smaller horizontal extension of the production table and / or in Extension direction of the desired profiling, arranged side by side are, the same partial area by only minor method, for. B. of common intermediate frame in succession first from the preformer and then be processed by Rippenstampfer. For this purpose, the Stamp plates of the two working elements also formed the same size.

The rib rammer is on his down facing contact page with equipped with a profiling, the negative shape of the desired later Profiling on top of the plate corresponds.

The preformer, on the other hand, is equipped with pairs of male connectors that are transversal to the main plane of the stamp plate projecting from this down and one Have height approximately the depth of the grooves of the later profiling, and with the slope of which, however, depending on a pair of down against each other approaching male connectors is closer together than the later groove of profiling.

This makes it possible, in an initially outwardly continuous layer of Aerated concrete these male connectors by placing the stamp plate of Preformer on the aerated concrete in these intrusions and there slightly back and forth, causing the male connectors the aerated concrete displace laterally and thus create gutters that are wider than the distance the male connectors, especially if the male connectors are not common but can be partially moved relative to each other.

For this purpose, the preformer has in addition to the vertical drive relative to the intermediate frame a pendulum drive for horizontal movement, preferably a float between two strokes, the on Preformer is formed.

The vertical drive - both the preformer and the rammer - relative to the intermediate frame carrying them comprises one or more Hydraulic cylinder for pressing the stamp plate down on the Surface of the aerated concrete.

The one or more intermediate frames are preferably in the vertical direction formed in several parts with a horizontal slewing ring in between to the course of the profiling of preformers and rip rammers according to the desired extension direction of the profiling of to be able to adjust later plate. For this purpose, the turntable rotatable at least 90 °, in particular rotatable in smaller steps / steps or even infinitely rotatable.

The rib rammer has a surface structure in the form of negative profiling to the desired profiling of the concrete slab.

The negative profiling of the Rippenstampfers can from separate surveys and these connecting floors are made of strip-shaped and are movable relative to each other in the vertical direction.

A particularly simple embodiment results when preformers and Rippenstampfer are fastened together on the same intermediate frame, because then only a turntable is needed.

The support frame on which the surface processing unit with preformer and Rippenstampfer hangs, can in the simplest case a central support column with a pivotally mounted thereto boom, on which the Machining unit hangs.

Such a one-sided projecting construction is easy to produce, but because of the only one-sided support little stable.

To provide compressive force on the top of the wall plate to a sufficient extent to apply and also to the relative positioning of the work table To reproducibly and accurately approach, there is the support frame preferably from a frame bridge extending over the production table, which sits on both sides on guide rails and is movable, the Machining unit is suspended from the frame bridge.

The guide rails are on the work table or the side rails of the Attached wall plate shape and the frame bridge preferably has four Flange wheels, with which it runs on the guide rails, of which at least one is drivable via a motor. The processing unit is along the frame bridge, ie transversely to the direction of movement, movable, by placing intermediate frames along guide rails at the frame bridge is movable, with this chassis again preferably motorized is driven.

All these Vorbewegungen are just like the other movements of Preformer and rip rammer from a central machine control semi-automatic or fully automatic controlled.

The chassis is on the frame bridge facing part of arranged multi-part intermediate frame.

The chassis of the frame bridge opposite the production table and / or the Intermediate frame opposite to the manufacturing bridge own Locking devices, by activating the current position of the Suspension can be fixed to a later unintentional procedure to avoid this working position.

In the direction of movement of the frame bridge is an exact positioning in accordance with the profile to be produced achieved by that the guide rails or profiled on the production table metal combs rise above the profiling of the cross-sectional shape of the produced Correspond to profile.

For fine positioning of the frame bridge can after coarse starting the Move working position of the rib rammer in the area of the sheet metal comb and be lowered with its profiling in its profiling, the fit exactly into each other, resulting in an exact working position of the Setting frame bridge, which then z. B. by activating the appropriate Locking device can be secured before in this working position of Manufacturing bridge of the processing unit a strip of the surface of the Wall plate is processed.

The device according to the invention serves to produce a wall plate 101 made of solid concrete with a facing shell 102 made of cellular concrete or the like, as shown in Figures 6 and 7, wherein the surface 103 of the cellular concrete 102 has a profiling 104, consisting of adjacent Troughs 106 and in between towering ribs 105, each oblique Flanks.

With only one header shell 102, the wall panel in one pass be prepared by placing in a horizontal plane with the main plane, after above open mold first - after Baustahlarmierungen already introduced were introduced - the solid concrete for the wall plate 101, distributed and is compacted and then, even before it hardens, the material applied to the facing shell 102, distributed and with the profiling 104th provided and compacted at the same time.

The preparation of a wall plate with shells 102 on both sides, such as shown in Figure 7, is possible in one pass only if one in Figure 7 not shown structural template as a negative mold on the bottom of the Wall plate shape are designed over the entire surface. Only then can in one Passage, so without waiting for the previous layer to cure must successively the lower header 102, the bearing wall plate 101 made of solid concrete and the upper facing shell 102 along with their profiling getting produced.

If you want to get along without a textured matrix, the only possibility is one one-sided with attachment shell equipped wall plate to produce according to Figure 6, to wait for their hardening, to take out of shape and 180 degrees turned, so with the facing shell 102 down, in the wall plate design lay down again and then on the still uncoated outside 107 of the supporting wall plate 101 to apply the second facing shell 102 and to profile.

For this purpose, the system according to FIGS. 1 to 5 and 8 to 10 is used:

Figure 8 shows in plan view and Figure 1 in the side view of the broad side ago the surface processing system 3 according to the invention, the one Manufacturing table 5 includes, over the on a support frame 4 in the form of a Frame bridge 17, the surface processing unit 2 is arranged in Figure 1 in two different functional positions, that is double, drawn.

The worktable 5 serves as a wall-plate mold 28 in that the upper side 5a of the Working table 5 serves as the bottom of the mold, from the boundary strips 29 as Stand up the side walls of the mold. The shape is thus free from above accessible, allowing the flowable concrete material before curing can be introduced, distributed and condensed.

Along the side edges of the work table 5 extend in the direction of the figure 1, ie along the narrow sides of the work table 5, guide rails 18, along which the frame bridge 17, each with two flange wheels 19 movable at least one of which is in communication with a drive motor 20.

The frame bridge 17 usually extends in the direction of extension 111 of the profiling 104 of the facing shell 102 of the wall plate 101, because this usually runs parallel to the narrow sides of the main plane of the wall plate 101st and is indicated in FIG. 1 for illustrative purposes only.

Along the frame bridge 17 is an intermediate frame 15, 15 'moved along of horizontally extending guide rails 22 on which a chassis 21st of the intermediate frame 15 'is movable.

The under the movable intermediate frame 15 'hanging intermediate frame 15th is opposite this to a turntable 24 with a vertical axis of rotation 25th rotatable.

In addition, the upper intermediate frame 15 'is formed in two parts with a Base part 16a, which is movable with the chassis 21 on the rails 22 and a contrast lowerable lifting part 16b, which in contrast vertical is relocatable.

On the intermediate frame 15 hang next to each other, a preformer 6 and Rippenstampfer 7, each via a hydraulic (with hydraulic cylinder 12), pneumatic or electromechanical drive 8 or 14 vertically opposite the intermediate frame 15 can be lowered until the pressing or Press into the top of the wall plate mold 28 stored on one even height deducted concrete material.

Both serve to treat each part of the surface by treatment of the work table 5 and thus the wall plate 101 successively first through the preformer 6 and then by the Rippenstampfer 7 the material of Front shell 102 on the one hand to compress transversely to the main plane 110 of the plate and at the same time in the surface 103, the desired profiling 104, consisting from the adjacent grooves 106 and ribs 105, and to provide In addition, the not yet cured materials of the wall plate 101 with the attachment shell 102 to connect.

For this purpose, the preformer 6 (see FIG. 9) points in the extension direction 111 of the subsequent profiling 104 extending vertically, and at the horizontally hanging die plate 6 'of the preform 6 projecting downwards Pairs of male connectors 9, which are inclined towards each other at their free ends run down, with the converging pairs to each other Have transverse distance which is less than the width of the later grooves 106th

By lowering the preformer 6 to the male connectors 9 in the material of Submerge bowl 102 and subsequent reciprocation of the Knife strips 9 transversely to their extension direction are roughly the grooves 106 of later profiling 104 formed.

In this case, all male connectors 9 of a preformer 6 together, for Example between two end stops 13 along guides 10, back and move and thereby form the grooves 106, as shown in Figure 5 can be seen. This is realized by a pendulum drive 11 which holds the stamp plate 6 '. horizontally reciprocated with respect to the base plate of the preformer 6 between the attacks 13.

The vertical movement is realized by means of the hydraulic piston 8.

However, a solution for the transverse movement can be chosen, in which the respective left male connectors 9a and the respective right male connectors 9b are interconnected and these two groups each relative to each other be moved, such as one group on the base plate 6 'and the other Group is attached to the stamp plate or the like.

In both cases, the displaced from the resulting grooves 106 material in between, piled up in the region of the resulting ribs 105, which is limited at the top by the die plate 6 'of the preform. 6

In the next step, after raising the preformer 6, the entire Intermediate frame 15 proceed accordingly, for example along the Frame bridge 17, until the same size in the supervision Rippenstampfer 7 is located on the same surface and now the Rippenstampfer 7 down lowered to the pre-profiled surface and pressed into the pre-profiling.

The Rippenstampfer 7 is profiled on its underside with a negative profiling 104 'corresponding to the final shape of the desired profiling 104 in FIG the attachment shell. He will be rough with his protrusions in the already preformed grooves 106 of the profiling 104 of the facing shell 102 pressed, and thereby the final shape of the profiling 104 is produced.

In this case, (see FIG. 10), the negative profiling 104 'of the rammer 5 from separate elevations 7a and arranged between them Soils 7b exist, which are movable relative to each other in the vertical direction. Then first the elevations 7a into the grooves 106 of the attachment shell pressed and this finally shaped, and only then the bottoms 7b of pressed on top of the upper ends of the ribs 105 of the profiling 104 and whose outer surface is shaped.

After just such a placement of the Rippenstampfers 7 is the Profiling 104 completed.

In this way, the entire top 103 of the facing shell 102 successively first each by the preformer 6 and then the Rippenstampfer 7 are processed by, for this purpose - each after prior lifting of the preformer 6 and rammer 5 until it stops Contact with the wall plate 101 advised - either the intermediate frame 15th along the frame bridge 17 is moved and then after editing of such a section, the frame bridge 17 along the work table. 5 move to the next section or vice versa.

It is important that the individually edited subsections as well Sections mutually overlap slightly and a consistently constant Profiling 104 is achieved.

By turning the turntable 24 by 90 °, for example Extending direction 111 of the profiling 104 of the transverse direction Be changed longitudinal direction of the plate.

Thus, the chassis 21 of the intermediate frame 15 and / or the chassis of the Frame bridge 17 also remains at a once approached working position, may have these locking means 26, via which a connection the respective guide rails with the wheels running thereon non-positively.

To the working position of the frame bridge 17 relative to the table 5 right to approach are on the guide rails 18 and directly on Manufacturing table 5 metal combs 27 arranged as positioning aids to the Preformer 6 or the Rippenstampfer 7 manually or automatically to the Align metal combs.

For this purpose - as can be seen in Figure 8 - the sheet metal combs 27 with a upwardly open profiling according to the later profiling 104 of Attachment shell 102 equipped.

Before by preformer and Fertigstampfer a new section, ie strip, the Plate is processed, the transverse position of this strip can be selected exactly Be by at the roughly preselected transverse position of the over the edge outside and thus over the sheet metal comb 27 extending away Fertigstampfer 7 is lowered down until its elevations 7a in the Immerse depressions of the profiling of the metal combs 27 and thereby the correct positioning in a horizontal direction is established.
