DE3909189A1 - Securing element (reinforcing material) for free-flowing and pourable substances and process and extruder head for its production - Google Patents

Abstract

To achieve securement against sliding movements within free-flowing and pourable substances, such as earthworks (embankments, dams, dykes), coastal and marine soil, massed snow and scree or the like, and on the underlying surface (avalanches), but also as a protection for young plants (marram grass) and during sporting activities (ski suit), a honeycombed securing element (reinforcing material) is provided as an inlay, overlay or underlay with friction-increasing openings and projections (spikes) or serrated edges. The one-stage continuous production process uses as a weld-joining medium for the strand elements of polymer melt extruded parallel next to one another compressed air which, in an alternating, primary controlling program, responds to contactless radiated pulses to effect in each case the deflection and joining of the strands, their perforation, spreading and deforming to form the projections or a latticework. The extruder head for producing the securing element (reinforcing material) comprises as the jet-deflecting means low-inertia, non-wearing resilient tongues, or alternatively: vibrating air feed tubes with nozzle ends, which avoid feeding in through the melt dies and in each case permit a direct and favourably directed impingement. Both are passively set in oscillating motion, assisting joining, by the electromagnetically (programmably) controlled compressed air surges.

Description

The invention relates to a reinforcing body for pourable and pourable materials such as earthworks, coastal or seabed, sand, Scree, snow masses or the like. These substances tend to accumulate Diverging and sliding in and on their surface. Environmental influences, wind, temperature, humidity, precipitation, currents movements, shocks, angles of inclination and, above all, structure of the Pads have an impact on the mostly desired cohesion.

For example, on a gas-covered slope in the mountains Avalanche danger with longer, smooth, downward-inclined stalks in space mean larger than with shorter grass stubble, which the com Secure the compact snow cover against slipping much better. A another example of the effect of the surface condition on the adherence of soil and covering is the landge Fencing and securing in the coastal area by fence-like tarpaulin tongue with beach grass or similar. The flying sand is returned there hold and pent up.

The invention has for its object with simple, easy to handle the stability and slip resistance suchi to improve the accumulation of substances and - in coastal soil or Seabed - to favor deposits and plant growth. Since the areas in question are usually large, the security measure to be taken must be particularly economical be. Other requirements are: simple geometry, stability and environmental resistance, easy assembly and disassembly options, far expandable but small storage volume, universal use and Reusability.

The inventive solution to this problem consists in the use of a reinforcing body for inserting, underlaying or supporting the pourable or pourable material accumulation, the body having a honeycomb structure composed of individual solid-walled ( 1 ) or lattice-shaped ( 34, 35 ) strip elements Has projections ( 3 ) or pin-like inclusions (spikes) ( 4 ), especially in the connection areas (seams) ( 2 ).

This honeycomb body could possibly be used instead of or in avalanche protection Supplement to the complex system of avalanche protection used Prevent masses of snow from slipping. Even smaller ones Snow fields (from approx. 10 × 15 m and 15 ° incline) form u. U. one potential danger. Before or during the snowfall station the body from a compact state with little stock space requirement, for example on a hillside meadow or the like spread out. The stored preload supports this the expansion process, so that, for example on a steeper slope, the Handling can only be done from above. If necessary, several stakes fastened in the ground in association with in the fall line in the Wa towing ropes arranged on the body ensure the sliding safety through the protrusions or spikes, increase. Because the protruding from the honeycomb walls in large numbers, protrusions penetrating deeper into the ground when loaded ge or spikes result in a positive fit with the ground Thrust protection. The snow becomes opposite a smooth floor supported in the cells of the honeycomb grid. The geometry of the body can be varied within wide limits. A measurement example has 50 to 100 cm mesh length, 10 cm high and 0.1. . . 0.2 cm thick strip elements made of polypropylene with approx. 2.5 cm high projections.

For heavy snowfall, form several layers Lay through the interlocking interlocking Protrusions or spikes provide increased support.

The same applies to when used in coastal areas Flying sand and running water sediments.

As a variant of the honeycomb geometry, continuous lengthways can also be used provide stripes. The position on the ground can be chosen arbitrarily, about so that these longitudinal stripes lie in the fall line and the Take over the task of the pulling ropes.

In a corresponding modification, the honeycomb body is also part of Use protective clothing for sports, such as an insert or pad of ski suits. The anti-glare and shock absorption effect when falling The further falling movement slows down on steep slopes. In slalom and Motorcycling protects smooth honeycomb tubes (of course without spikes) Head and body from bruises and abrasions.  

There are other possible applications in the protection of Plants against game browsing, when securing dikes, as fill bodies in cooling towers and sewage treatment plants, as a replacement for snow chains Road vehicles, as protective mats on ski slopes. . . etc.

The honeycomb strips can also be made of foam instead of all-plastic plastic or fiber-reinforced plastic or the like.

The sliding friction on the floor can be increased considerably by roughening, corrugating or interlocking the narrow, overlying ones Outer surfaces of the strip elements.

Openings or dents in the connection area of the strip elements facilitate the formation of the protrusions during manufacture. Outside They also allow traction ropes to pass through to the Stabili and soil growth.

The reinforcement-like insert of one or more teeth layered reinforcement body in pourable or pourable Substances such as soil or the like, concrete, rubble, snow masses a solid cohesion. The reinforcing body itself can be from Raw material forth with glass, carbon or aramid fibers intrinsically ver be strengthened.

The method for producing the reinforcing body is based on the Patent application DE 23 36 313 A1. There they are parallel from ne juxtaposed nozzles extruded strip elements Change pressure medium jets with constant pressure (compressed air) deflected laterally and ver together to a honeycomb network welds. The pressure medium nozzles are located closely between the masses at the end of an additional energy-consuming transmission be push-pull tubes with many bearings. The Ver bond areas have the same height and double throughout Thickness like the stripe elements.

In contrast, according to the invention, the pressure medium jet becomes a pressure vibration - up to ultrasonic frequencies - superimposed to a fe to achieve more welding. The beam initially acts strengthens in the middle connection area to a flattening or Per to achieve foration, the thermoplastic strip mass  during continuous extrusion to form one-sided widened and ver outwards or ver is pushing. This enables a larger and more stable shape height. Higher pressure values are used here.

Then the beam effect is used to form the protrusion tips shifted outside.

The measure also serves this purpose, according to the rays an initial movement parallel to the direction of extrusion to be given via (one-sided) right-angled motion component, to distort the opening and / or the outer ends to sharpen the tabs.

Depending on the requirement and the nature of the floor, prefabricated Te metal pins (spikes) useful as a deep anchor be. They can be cycled in front of or in the connection area lead - for example by a vacuum or magnet-controlled manipulation device - and through the pressure medium surges with or without protrusion Weld the ge firmly into the connection.

Friction-increasing projections, but with a smaller height (and en smaller division) also arise if between the effects conditions of the pressure medium when connecting two strip elements each Honeycomb body, each stripe element on both sides simultaneously under pressure medium beam is applied, d. i.e. when during extrusion of the free strip lengths jet all pressure medium nozzles at the same time have effects. Extrusion speed and pressure medium frequency determine the distances between the embossed tooth-like projections Fluid pressure their height.

For reasons of material savings, but also to increase the stand safety (such as on grass or sand, where grass plants or Beach grass through the mesh) is another general one Variant of the invention is advantageous: the strip elements are instead designed as solid walls, as lattice walls. The lattice structure comes in that first the plastic mass instead of each egg ner nozzle opening corresponding to the full strip cross-section, now strips of several each, roughly rewritten in the original  round cross-sectional nozzle opening emerges thread-like, the honeycomb welded joints as in the solid litter fen are generated and the cross-linking welding connections through the intermittent simultaneous release of all pressure media rays arise; so as above for the procedure for the smaller, friction-increasing projections described.

The thread elements extruded close to each other are obtained by the Beam blows several times between the individual honeycomb connections Abplat tings with laterally protruding, with their neighboring threads welding projections. After formation of the honeycomb connections at ge compared to the solid threads faster cooling of the thread cross-connection conditions (cold pressure medium and thinner cross sections) can be NEN stretching process, the warmer ones, or later again warmed thread cross sections (lengthwise) stretched and thus in diameter be reduced, increasing the free air mesh, also in the transverse direction.

For other uses, such as packing or trickling in Sewage treatment plants, cooling towers or filters can be used after this last Another feature of the process is also continuous pipes or mats etc. without honeycomb connections, with orthogonal geometry.

The manufacture of the honeycomb body or lattice body could instead of how described so far in the one-step procedure the generation heat, alternatively also using prefabricated finished, reheated full or grid strip elements, and the honeycomb connections can also be separated Effect technologies. However, quality and economy would be considerably less favorable.

Another object of the invention is the spray head for off Exercise of the new extrusion blow welding process shown. High quality connections of the extruded strands with the sweat factor 1 require that - with restricted structural space - the pressure medium jet near the strand nozzle mouth and the fresh strand surface, concentrated and with a precise direction of action from the Pressure fluid nozzle emerges and strikes. In the well-known Spritz  Head according to DE 23 36 313 A1 are of two alternately be long tubes branching openable distribution channels seen with their nozzle openings through holes between the slot-shaped nozzles for the plastic strands up to the area in front, but pass through the mouths of these nozzles. These two tube groups are countered by a special gear cycles back and forth, synchronized with the pressure medium surges.

According to the invention, this admission system is essentially ver simply by using vibratable, outside the Spraying thin, protruding in front of the fluid nozzle Spring tongues with a streamlined W-shaped cross-section, that is similar to a rounded w. The tongue is when the nozzle is depressurized at the nozzle mouth to the deflection and welding process at ak not to hinder activated neighboring nozzles. In the pressurized Condition lifts the tongue through the impinging jet of pressure medium elastic, moves a short distance with the strands up to an adjustable stop, thereby splitting the beam and directs it around 90 degrees on both sides in the direction of the two neighboring strands that move across it with their other night Weld bar strands.

This system does not require a special gear with energy consumption and avoids the many plain bearings of the tubes and ver divider channels. It is also wear and maintenance free. The ener pourable natural vibration frequency is due to a movable Adjustable weight. Further profiles of the tongue to the beam differentiation can be made if necessary. Interchangeable Inserts, such as copper, for the fluid nozzle orifices, he by adapting their mouths, they adapt to rheology cal requirements (pressure distribution).

A modification of the two alternating groups of effects Pen of the pressure medium supply and its control brings more Advantages in the design of the nozzles at the end of the pressure medium ka channels. These channels do not need the strand here in the narrow space nozzle carrier plates to be incorporated, but can, independently gig as an elastic springy tube, the nozzle-carrying ends up reach close to the strand nozzles, trained and from the outside on Spray head must be fixed or movable. So you're one  separate function group on common extrusion heads to be installed as a nozzle attachment. Number and cross sections of the print middle nozzles can be in any shape (e.g. round or slit-shaped) incorporated into the end of the tube or exchangeable. It leaves a defined beam deflection and beam effect can be achieved. Lifting off the nozzle system is done either by the rear downward jet recoil, if necessary by directly against the Nozzle carrier plate directed additional nozzle opening, or through the Bourdon tube effect if the pressure medium tube is appropriate is bent, possibly with a winding loop. For a special end The projections can be shaped by a cam, depending on the Tact the tube end slides, also a sequence of the beam movement in the direction of the strand exit and then perpendicular to it in stripe height.

Fig. 1 shows the on the ground 8, as a grassy slope of outstretched, honeycomb-shaped basic structure reinforcing body. In the front, right part you can see a simple (welded) connection point Ver two strip elements 1 , which is preferably made in the extrusion blow welding process according to DE 23 36 313 A1. Three variants according to the invention, each of which can be present individually or in combination with one another in a coherent body, are shown in the same FIG. 1: In the middle, on the right, is an embodiment of the connection point (weld seam) 2 of two strip elements each 1 with projections on both sides 3 , which are anchored in the subsurface 8 . On the left there is an opening, dent or hole 5 . Meh rere pegs 6 , above, are hammered into the ground and give the reinforcement body additional hold, also possibly in association with the pull cables 7 , which at each connection point 2 or only ever at the upper ( 6 ) and lower end of the reinforcement body could be. In the lower left part of FIG. 1 you can see as a further modification, the friction-increasing teeth 32 of the Wa benwand (strip elements). 1 It provides additional slip resistance. Another variant shows the upper, middle part of FIG. 1, where a grid strip element 33 with the horizontal, thread-like strands 34 and the vertical cross connections 35 , the Strei fenelement 1 correspond. The large number of transverse openings created with this profiling increases the adsorption surface z. B. for snow and ice crystals or sand or sediments, but also for supporting young plants.

Fig. 2 shows the reinforcing body in a collapsed, compact state, z. B. for storage, in which the internal voltage before the honeycomb geometry can be high or low depending on the preceding heat treatment. In the former case, a fixing wrap is required for storage. The holes 5 are here, for example, a kind of diamond-shaped cut.

The Fig. 3 may be the variant of the junction 2 with a welded-in spike-like pin 4 (with or) without projections 3 recognize.

Fig. 4 shows in a cross section through the slope 8 with penetrated protrusions 3 or pins 4 an option to connect the strip elements offset to each other in height, so that an oblique honeycomb geometry, which adapts approximately to the Hangnei, arises.

In Figs. 5 to 9 construction and operation of the spray head are shown for the manufacture of the reinforcing body. The plasticized plastic mass 19 , such as polypropylene, comes in the direction of the arrow from a normal extruder, not shown, and flows via a connecting flange 10 into the spray head housing 9 of a normal slot die, for example with a “clothes hanger” cross-distributor 11 ( FIG. 5).

The nozzle holder 12 , which is mounted instead of the wide-slot lips, accommodates the parts 13 to 23 as a compact attachment unit in and of itself. The mass flow 19 evenly distributed over the nozzle width (eg 1.5 m) then emerges through the nozzle slot openings 13 into the free atmosphere. The nozzle channels 14 for the pressure medium (air), which are divided into two action groups and are arranged parallel to and between the mass nozzles 13 , are alternately connected to the distributor channels 15 and 16 . These can be connected to a pressure medium source (compressed air network, approx. 2 to 6 bar, if necessary via a vibrator), alternatively or simultaneously, via a programmable controlled, not shown, solenoid valve.

For transverse deflection and welding of the strip elements 1 , immediately at the nozzle mouth 13 , the compressed air jet 18 must be divided and deflected approximately 90 °. In a first embodiment according to FIG. 5, this deflection means is designed according to the invention as a spring tongue 17 . It is fastened with its one end 23 to the nozzle holder 12 . The other, freely swinging end 17 lies with a slight bias against the mouth of the nozzle channel 14 , covering it. This oscillating tongue 17 is located in front of each nozzle 14 , ie between the nozzles 13 (for example 100 pieces, each 15 mm laterally apart). The free end is 17 W-shaped for low-loss beam deflection. Each time the air jet 18 emerges abruptly, the spring tongue 17 lifts off the nozzle system 14 and moves up to a (or more) adjustable stop 22 . The air jet is divided into two halves, each blowing apart at approximately 90 °, which meet directly against the adjacent freshly extruded strip elements 1 , deflect them and bring about welding to the connecting region 2 , the direction, intensity and duration of the height of the corresponding projections 3 or determine the shape of the holes 5 . The adjustment of the air jet effect 18 to the desired connection shape ( 2, 3, 4, 5 ) can be made by easily deformable inserts 20 for the nozzles 14 (e.g. made of copper) ( FIGS. 6 and 7). The deduction in the direction of arrow V , the cooling and cutting to length of the finished reinforcement body are done in a usual manner by known means, not shown.

Fig. 8 shows the above to Fig. 5 in side view described relationships again in plan view (to the right ver sets). To the left, in the direction of arrow V , the finished honeycomb structure moves. The interplay of the spring tongues 17 is clearly visible here. In the cycle according to claim 9, with simultaneous swinging exit of the air jets 18 , all spring tongues 17 are on the left at the stop 22 . The adjustable weight 21 allows the natural frequency of the spring tongue 17 to be adapted to the air jet frequency, in order to save energy. Electrical feedback of the vibration to the solenoid valve in the air supply line would also be possible.

A view in front of the spray head in the direction C of FIG. 5, that is, in the direction opposite to the exit direction, is shown in FIG . But also by differentiated impressions of the individual supply tubes Ge speed and amount of air jets can be matched.

The reinforcing body can also be produced in the closed tube shape, for example for use as protective clothing, using the same manufacturing method instead of in a flat path, as shown in FIGS . 10, 11 and 12. If necessary, a later longitudinal cutting and spreading the plan again results in the flat mat geometry. The numbers corresponding to the part numbers of FIGS. 5 to 9 are provided with an index line '.

Referring to FIG. 13, in which the head construction with nozzle slots 13 '' to that of FIG. 10 corresponds to (part numbers with index Two stick '') is in modification of the beam deflection and the Blaszuluftleitung, instead of the spring blade 17, 17 ', a System of spring tubes 25 to 29 provided. They combine the functions of blown air supply, jet deflection and free swinging. This eliminates the necessity that the blown air nozzles 14 must be incorporated into the nozzle holder 12 in the confined space between the mass nozzles 13 . This system also allows the blowing nozzles to be designed freely and brought close to the extruded mass strands. Fig. 14 corresponds to Fig. 11 and Fig. 16 of Fig. 12. The Blasluftdü sen 28, 29 are located at the end 27 of the spring tube 25, 26 , the other end of the distribution channels 15 '', 16 '' fixed or be movable (e.g. rotatable) is connected. The distribution channels are fastened to the spray head housing 9 with a holder 30 .

To increase the elasticity, the tubes 25, 26 are expediently bent and flattened ( 25 ) or designed as a spring turn ( 26 ). In this way, the so-called Bourdon effect can be exploited: When pressurized by the blown air, the tube end 27 stretches out of the system shown in FIG. 13 fully drawn on the mass nozzle 13 into the raised, dash-dotted position at the stop 22 '' . This creates, depending on the geometric positioning of the spring tubes, an oblique movement of the blowing nozzles 28, 29 , thus with vertical components, which, here one-sided, favors the formation of the projections 3 in the connec tions 2 of the strip elements 1 .

In Fig. 14 inclined blown air jets 18 '' with a small stem distance, therefore with a large deformation effect to the outside, he is recognizable.

Fig. 15 shows a way to divide the movement of the blowing nozzle in a first horizontal and then vertical Wegab section. The spring tube end 27 slides on a cam cam.

An enlarged cross section compared to FIG. 16 through the area of the blowing nozzles 28, 29 , with the air jets 18 '' and possibly an additional recoil nozzle directed towards the nozzle carrier 12 '' in the middle, above, is shown in FIG. 17.

In Fig. 18 a variant of the blowing nozzles 28, 29 is shown, with egg ner, approximately diamond-shaped or cross-slot-shaped cutting nozzle 31 on the tube chen 25 ' to z. B. holes 5 according to FIG. 2 in the connections 2 .

This principle of the process can also be constructed as a slot or Round system can be realized.

The shape, number and combination of the nozzles, action groups and the pressure medium as well as the control program can be modified accordingly. For example, superimpositions and / or sequences of pressure medium pulses or vibrations of the first order (quasi-ultrasonic welding), second order (interlocking of the honeycomb strip edges 32 ) and third order (connection area 2 ), etc., or the like, can be carried out.

Since the reinforcing body according to the invention consists exclusively of (before preferably environmentally friendly) plastic, it can be full reprocess. Depending on the intended use, the plastic can be set so that after some time it is affected by the environment kung is degraded or that it is environmentally resistant.
