SPOJNI ELEMENT ZA PROJEKTIRANO REGOJOINT DESIGN FOR DESIGNED REGO
Izum se nanaša na spojni element za projektirano rego (v orig. Soliriss-Fugenschiene).The invention relates to a coupling element for a projected reg (in orig. Soliriss-Fugenschiene).
Pri betoniranju daljših neprekinjenih delov sten nastanejo zaradi krčenja betona pri vezanju razpoke, ki lahko vodijo do netesnosti v steni. Zato se posebno pri stenah, ob katerih se nabira voda, na določenih mestih izdelajo projektirane rege z vnašanjem elementov, ki zmanjšujejo presek zidu. Rege se zatesnijo skozi elemente, ki tvorijo rege, tako da je tesnost stene zagotovljena.When concreting longer continuous portions of walls, they are caused by shrinkage of concrete in the bonding of cracks, which can lead to leaks in the wall. Therefore, especially for walls where water accumulates, projected joints are made in certain places by inserting elements that reduce the cross-section of the wall. The joints are sealed through the elements forming the joints so that the tightness of the wall is ensured.
Običajno se za izdelavo tovrstnih spojev za projektirano rego (v orig. Sol 1riss-Fuge) uporabljajo spojne tesnilne cevi, ki sestojijo iz cevastega spojnega traku in iz cevi za ostoženje iz trdega PVC.Typically, joint sealing tubes consisting of a tubular joint strip and a rigid tube of rigid PVC are used to make such joints for the projected reg (in orig. Sol 1riss-Fuge).
Z montažo spojnih tesnilnih cevi v centru stene in istočasnim nameščenjem trirobnih letvic na notranji in zunanji strani, se presek stene namensko zmanjša. Zaradi tega se razpoke zaradi krCenja krajevno omejijo in zatesnijo s spojnim trakom.By installing connecting sealing tubes in the center of the wall and simultaneously installing triangular slats on the inside and outside, the cross section of the wall is purposefully reduced. As a result, shrinkage cracks are locally restricted and sealed with a connecting tape.
Cevasti spojni trak se pri tem zavari s spojnim trakom, ki poteka horizontalno v prehodu talne plošCe proti steni, tako da nastane za vodo neprepustna elastična plast.The tubular joint strip is then welded with a joint strip extending horizontally in the passage of the floor slab towards the wall, so that a watertight elastic layer is formed.
Pri tem načinu spojnih tesnilnih cevi je pomanjkljivo, da se spojna tesnilna cev ne more postaviti na površino talne plošče, na katero se betonira stena, ker sicer lahko voda vdira v vzdolžni smeri spojnega tesnilnega prostora.In this method of joint sealing tubes, it is disadvantageous that the joint sealing tube cannot be placed on the surface of the floor slab on which the wall is concreted, since otherwise water may intrude in the longitudinal direction of the joint sealing space.
Dalje so poznani spojni elementi za projektirano rego, ki so oblikovani iz ploščatih votlih ali polnih elementov (v orig. Schiene) z več komorami, potekajočimi v vzdolžni smeri. Ti elementi imajo določeno debelino, da bi lahko na vzdolžno potekajoči ozki strani vključili nek nabrekljiv trak v utoru. Nabrekljivi trak se nanese tudi na ozki strani elementa, ležečega na tleh, da bi se zagotovila zatesnitev v spoju med talno ploščo in steno, ki jo je treba betonirati. Ta nabrekljivi tesnilni trak, predviden na spodnji ozki strani elementa, je treba potem spojiti z nadaljnjimi nabrekljivimi tesnilnimi trakovi, potekajočimi v vzdolžni smeri spoja med talno ploščo in steno, ki jo je treba betonirati, s čimer se doseže običajna zatesnitev celotnega spojnega območja s pomočjo nabrekljivega traku.The following are known to be designed elements for a projected reg, formed from flat hollow or solid elements (in orig. Schiene) with several chambers extending longitudinally. These elements have a certain thickness to allow for a swollen ribbon in the groove on the longitudinally narrow side. An inflatable strip is also applied on the narrow side of the element lying on the floor to provide a seal in the joint between the floor slab and the wall to be concreted. This swollen sealing strip provided on the lower narrow side of the element must then be joined with further swollen sealing strips extending longitudinally between the floor plate and the wall to be concreted to achieve the normal sealing of the entire joint area by means of swollen tape.
Pri tem uporabljeni elementi z votlimi komorami se izdelujejo iz umetne snovi. Dalje je treba uporabiti bodisi zelo močne nabrekljive trakove, da bi se zagotovila zanesljiva zatesnitev, kar spet poveča stroške za spojni element za projektirano rego ali dopusti samo omejeno zmožnost tesnjenja, kar pri lokalno visokih vodnih tlakih ne zadostuje. Naknadna zatesnitev tovrstnih spojev za projektirano rego, zatesnjenih z nabrekljivimi trakovi, se lahko izpelje bodisi samo od zunaj ali je izredno draga, če naj bi se popravila tesnitev ob elementu samemu. Betonska stena se mora tedaj odpreti ali se lahko lokalno zatesni z od zunaj izvedljivim, vendar zelo dragim postopkom točkastega vbrizganja.The hollow chamber elements used here are made of plastic. Furthermore, either very strong swelling straps should be used to ensure reliable sealing, which again increases the cost of the coupling element for the projected lug, or allows only a limited sealing capacity, which is insufficient at locally high water pressures. The subsequent sealing of such joints for the projected reggae, sealed with swollen straps, can be done either from the outside only or is extremely costly to repair the sealing of the element itself. The concrete wall must then open or be sealed locally with an externally feasible but very costly point injection process.
Pri tem uporabljeni nabrekljivi trak nabreka pod vplivom vode. Nabrekljivo sredstvo je neka hidrofilna masa, ki je vložena v nosilni snovi, večinoma kloroprenski gumi. Nosilna snov ima predvsem nalogo, da daje nabrekljivemu sredstvu stabilnost in elastičnost. Hidrofilna (vodo vsrkajoča)The swelling strip used here is under the influence of water. A swellable agent is a hydrophilic mass embedded in a carrier substance, mostly chloroprene rubber. The carrier is primarily intended to give the swelling agent stability and elasticity. Hydrophilic (water absorbent)
-3~ komponenta vsrka vodne molekule in poveča s tem svoj volumen za 1,5 do ca. 4 krat. Pri tem nastane tlak do 6,5 bar, ki izpolni okoliške votle prostore in naj bi jih s tem napravil nepropustne za vodo. Pri uporabi tovrstnih nabrekljivih sredstev je treba upoštevati, da se nabrekljiva masa ne razteza hitro, ampak počasi v teku ur ali drii in se zatorej lahko uporablja v spremenljivih območjih z mokrimi in suhimi periodami samo omejeno. Markantna prednost nabrekljivih sredstev, zaradi česar se Cesto uporabljajo, je v njihovi možnosti, da zanesljivo zatesnijo spoje med različnimi materiali, kot na primer beton/umetna snov, beton/železo in tako dalje.The -3 ~ component absorbs the water molecule and thereby increases its volume by 1.5 to ca. 4 times. This produces a pressure of up to 6.5 bar, which fills the surrounding hollow spaces and thus makes them watertight. When using such swelling agents, it should be borne in mind that the swelling mass does not stretch rapidly but slowly over the course of hours or driers and therefore can only be used in variable areas with wet and dry periods. The striking advantage of swelling agents, which is why Road applications are used, is their ability to reliably seal joints between different materials such as concrete / plastic, concrete / iron and so on.
Dalje so poznane tesnilne priprave za zatesnjenje spoja, ki obstaja med dvema betoniranima deloma, ki tvorijo kanal, skozi katerega se neko sredstvo za injektiranje vbrizga v spojno področje pod visokim tlakom in ga zatesni.Further known are sealing devices for sealing a joint that exists between two concreted parts that form a duct through which an injection medium is injected into the joint area under high pressure and sealed.
V CH-PS 600 077 je opisana cev, ki sestoji iz opornega telesa v obliki spiralne vzmeti, ki je obdano z neko prvo pleteno cevjo, ki je spet obdana z zunanjo, mrežasto porozno cevjo. Po montiranju te tesnilne priprave iri betoniranju drugega betoniranega dela se tesnilni material vtisne v cevasto tesnilno pripravo, ki naj bi izstopala na prostih mestih betona. Tovrstna cev je priprava, ki jo je mogoče izdelati le sorazmerno zapleteno.CH-PS 600 077 describes a tube consisting of a support body in the form of a spiral spring, which is surrounded by a first braided tube, which is again surrounded by an outer, mesh porous tube. After mounting this sealing device or concreting another concrete part, the sealing material is pressed into the tubular sealing device, which should stand out at the vacant positions of the concrete. Such a pipe is a device that can only be made relatively complicated.
Da bi lahko tovrstno porozno cev bolje ščitili pred zamašitvijo z betonsko goščo, se v DE 83 35 231 Ul predlaga, da se med oporno telo v obliki spiralne vzmeti in zunanjo mrežasto cev vstavi nek nepleten material, ki je prepusten za tekočino, neprepusten pa za fine betonske delčke.In order to better protect such a porous tube from clogging with a concrete slurry, it is proposed in DE 83 35 231 Ul that a non-woven, fluid-permeable, impermeable material is inserted between the support body in the form of a spiral spring and the outer mesh tube. fine concrete particles.
Končno je iz DE 86 08 396 Ul poznana nadaljnja tesnilna priprava v obliki cevi za vbrizganje, ki hoče po eni strani odpraviti pomanjkljivosti pri pozicioniranju cevi s spono, /i predvideno na telesu cevi in po drugi strani predlaga predvideno mesto preloma v vzdolžni smeri cevastega telesa, skozi katerega naj bi tesnilni material izstopal v beton.Finally, a further injection device in the form of an injection tube is known from DE 86 08 396 Ul, which seeks, on the one hand, to remedy the defects in the positioning of the tube with the clamp provided on the tube body and, on the other hand, proposes the intended fracture location in the longitudinal direction of the tubular body , through which the sealing material should protrude into the concrete.
Gradnja teh cevi je z napredujočim razvojem vedno bolj komplicirana in dražja, s Čimer naraščajo tudi stroški leteh. Dodatno obstoji nevarnost, da se te cevi pri betoniranju zmečkajo, tako da je vbrizganje materiala za injektiranje težavno.The construction of these pipes is increasingly complicated and costly with the advancement of development, which also increases the cost of flying. In addition, there is a risk that these pipes will become crushed during concreting, making injection material difficult.
Zato je bila v EP 0 418 699 Al predložena tesnilna priprava, ki sestoji iz v preseku odprtega, v obliki pokrova izoblikovanega profila, ki je s prostimi vzdolžnimi robovi svojih stranskih območij montiran nasedajoče na betonski površini, tako da nastane pretočni kanal za tesnilni material med profilom in betonsko površino. Tesnilni material se pod visokim tlakom uvaja v pretočni kanal in izstopa med prostimi vzdolžnimi robovi profila in površino betona na prostih mestih betona. Nadaljnja v tem opisana tesnilna priprava sestoji iz telesa, ki sestoji iz penaste snovi oz. traku iz penaste snovi s prehodnimi porami, prednostno s pravokotnim presekom, ki je montiran nasedajoče na površini betona, tako da se tvori prehodni kanal za tesnilni material skozi telo samo, pri Čemer tesnilni material izstopa iz prehodnih por v območje spoja.Therefore, a sealing device is presented in EP 0 418 699 Al, consisting of an open section shaped like a cover, which, with the free longitudinal edges of its lateral regions, is mounted seated on a concrete surface, thus forming a flow channel for the sealing material between profile and concrete surface. The sealing material is introduced under high pressure into the flow duct and protrudes between the free longitudinal edges of the profile and the concrete surface at the vacant sites of concrete. Further, the sealing device described herein consists of a body consisting of a foam material or a foam. a foam strip with transitional pores, preferably a rectangular cross-section, which is mounted adjacent to the concrete surface, so that a passage channel is formed for the sealing material through the body only, whereby the sealing material protrudes from the transitional pores into the joint area.
Tesnilna priprava predstavlja sicer občuten napredek v primerjavi z običajnimi cevmi, ni pa mišljena za uporabo v spojih za projektirano rego, ker se enostransko odprt profil položi na že gotovi betonski površini talne plošCe, da bi tvoril kanal za vbrizganje. Pri izdelavi spojev za projektirano rego pa se priprave, ki tvorijo spoje za projektirano rego, dobetonirajo z obeh strani, tako da bi se tovrsten enostransko odprt profil polnil z betonom.Although the sealing device represents a significant improvement over conventional pipes, it is not intended to be used in joints for the projected sling, since a single-sided open profile is laid on a ready-made concrete surface of the floor slab to form an injection channel. In the manufacture of joints for the projected reggae, the devices forming the joints for the projected reggae are knocked on both sides, so that this unilaterally open profile is filled with concrete.
Iz DE 93 20 134 Ul je za zatesnitev spojev za projektirano rego poznan spojni element, v katerega se da vbrizgati. Ta spojni element je izoblikovan z obojestransko razporejeni mi rebri in sestoji iz ekst rud i ranega profila, ki ima v srednjem delu v vzdolžni smeri vsaj en intregriran prehodni kanal. Kot izstopno odprtino ima ta prehodni kanal zarezo, potekajočo v vzdolžni smeri, ki je zaprta z oblikovno usklajeno vloženim tesnilnim trakom. Tesnilni trak se pri vbrizganju tekočine za vbrizganje odpre podobno kot ventil tako, da lahko tekočina za vbrizganje izstopi iz kanala za vbrizganje.DE 93 20 134 Ul is known for injecting a connection element into a projected rego into which it is injectable. This coupling element is formed by two ribs arranged on both sides and consists of an extruded profile having at least one integregated transition channel in the median longitudinal direction. As an outlet, this passage channel has a notch extending in a longitudinal direction, which is closed by a formally aligned sealing strip. When injecting the injection fluid, the sealing strip opens much like a valve so that the injection fluid can exit the injection channel.
Ta spojni element ima v primerjavi z običajnimi spojnimi elementi, izoblikovanimi brez kanala za vbrizganje, v primeru naknadnega tesnjenja pomembno stroškovno prednost. Vendar je izoblikovanje kanala za vbrizganje drago, ker je predviden votel kanal, ki je zaprt s posebej oblikovanim tesnilnim trakom. Za obojestransko zatesnitev sta potrebna dva kanala za vbrizganje, s čimer se sicer zanesljivost pri postopku tesnjenja zviša, stroški takega spojnega elementa pa ustrezno naraščajo.This joint element has a significant cost advantage in comparison to conventional joint elements formed without an injection channel. However, designing an injection channel is expensive because a hollow channel is provided, which is closed with a specially designed sealing strip. Both seals require two injection grooves, which otherwise increases the reliability of the sealing process and the cost of such a coupling element increases accordingly.
Enostavnejša varianta spojnega elementa z obojestranskim zatesnjenjem je razvidna iz DE 41 40 616 Al, zlasti iz Fig. 4. Ta spojni element je na eni strani izoblikovan s kanalom za vbrizganje in ima na strani, ki je obrnjena stran od kanala za vbrizganje n a b r e k1 j i v trak. Kanal za vbrizganje in n a breki jivi trak sta pri tem s hrbtom ob hrbtu nameščena na spojnem elementu.A simpler variant of the coupling element with double-sided sealing can be seen in DE 41 40 616 Al, in particular FIG. 4. This coupling element is formed on the one hand by an injection channel and has a ribbon on the side facing away from the injection channel. The injection groove and the nozzle strip are mounted on the coupling element with their backs along the back.
Dalje je v DE 93 15 974 Ul opisana spojna pločevina, na katero je pritrjena cev za vbrizganje. Cev za vbrizganje nalega približno preCno središčno na nepredrti spojni pločevinasti steni in je nameščena v prostem prostoru med spojno pločevinasto steno in namensko steno, ki ima odprtine.Further, DE 93 15 974 Ul describes the connection plate to which the injection tube is attached. The injection tube rests approximately transversely centrally on the unopened connecting sheet metal wall and is positioned in the open space between the connecting sheet metal wall and the purpose wall having openings.
Stanje tehnike se torej da povzeti v tem smislu, da obstajajo spojni elementi za zatesnitev spojev za projektirano rego, ti tudi zagotavljajo zanesljivo zatesnitev, zlasti Ce imajo na obeh straneh kanale za vbrizganje. Če se izvedba spojnega elementa poenostavi, se s tem sicer stroški spojnega elementa zmanjšajo, vendar upade zanesi jivost, s katero je spoj za projektirano rego zatesnjen.The state of the art can therefore be summarized in the sense that there are joints for sealing joints for the projected reg. These also provide reliable sealing, especially if they have injection channels on both sides. If the design of the coupling element is simplified, the cost of the coupling element will be reduced, but the reliability with which the coupling for the designed regu- lation is sealed will decrease.
Obstoji veliko število stroškovno ugodnih enostavnih izvedb spojnih elementov, ki pa imajo samo na eni sami st ra ti i kanal za vbrizganje in zato zatesnijo samo enostransko s pomoCjo sredstva za injektiranje.There are a large number of cost-effective, easy-to-implement couplings, which, however, have a single injection channel on a single site and are therefore sealed only unilaterally by means of an injection means.
To veliko število enostavnih izvedb kaže, da obstoji znatna potreba po enostavnih, stroškovno ugodnih spojnih elementih za spoje za projektirano rego, ki istočasno zagotavljajo visoko zanesljivost pri zatesnitvi s pomoCjo sredstva za i n j e k t i r a n j e.This large number of simple embodiments indicates that there is a considerable need for simple, cost-effective joints for projected-joint joints, which at the same time provide high sealing reliability with the aid of an i n j e k t i r a n e.
Osnova izuma je zaradi tega naloga, da ustvari enostaven, stroškovno ugoden spojni element za izdelavo spojev za projektirano rego, ki omogoča zanesljivo, tudi naknadno izvedljivo zatesnitev spoja za projektirano rego.The object of the invention is, therefore, to create a simple, cost-effective joint element for making joints for the projected reg, which enables reliable, and subsequently feasible, joint sealing for the projected reg.
Naloga je rešena s spojnim elementom za projektirano rego, z značilnostmi zahtevka 1.The task is solved by a coupling element for the projected reg, with the characteristics of claim 1.
S predvidenjem vodilne letvice (v orig. Schienenlatte) v obliki traku, z na njej nameščeno napravo, ki tvori kanal za vbrizganje, raztezajočo se preko celotne dolžine vodilne letvice, se ustvari priprava, ki je primerna za izdelavo projektirane rege in dopušča naknadno zatesnitev z vbrizganjem tesnilnega materiala v kanal za vbrizganje.By designing a guide strip (in orig. Schienenlatte) in the form of a strip, with a device mounted thereon forming an injection channel extending over the entire length of the guide strip, a device is created which is suitable for making a projected gap and permits subsequent sealing with injection of sealing material into the injection duct.
Ker je v vodilno letvico v območju stika naprave, ki tvori kanal za vbrizganje, narejena perforacija, lahko vnesemo s spojnim elementom za projektirano rego v smislu izuma sredstvo za injekti ranj e na obeh straneh spojne letvice v sosednje betonske odseke celo, če ima spojni element samo en sam kanal za vbrizganje, S tem se zanesljivost naknadne zatesnitve pri enostavnem načinu izvedbe bistveno poveča.Since a perforation is made into the guide strip in the area of contact of the device forming the injection channel, a means of injection on both sides of the connecting lane into the adjacent concrete sections can be introduced by means of a connecting element for the projected reg. only a single injection channel, This significantly increases the reliability of post-sealing in a simple way of execution.
Dalje dopušča perforacija pri spojnem elementu z dvema kanaloma za vbrizganje, ki sta nameščena na nasproti ležečih straneh v območju perforacije, da se površina preseka kanalov za vbrizganje zmanjša, ker oba kanala za vbrizganje komunicirata preko perforacije in se lahko lokalno oviranje funkcije enega kanala izravna skozi paralelno potekajoči kanal za vbrizganje, nameščen na drugi strani vodilne letvice.It further permits perforation at the coupling element with two injection channels arranged on opposite sides in the perforation area, to reduce the surface of the intersection of the injection channels, since both injection channels communicate through the perforation and the local obstruction of the function of one channel can be compensated through a parallel injection groove located on the other side of the guide rail.
Ugodne izvedbe izuma izhajajo iz opisa in podzahtevkov.Advantageous embodiments of the invention arise from the description and the sub-claims.
za projektirano rego v smislu izuma.for a designed reggae according to the invention.
Spojni element za projektirano rego v smislu izuma sestoji iz vodilne letvice 1 približno v obliki traku in iz vsaj ene na tej nameščene naprave, ki tvori kanal za vbrizganje, raztezajoče se preko celotne dolžine vodilne letvice 1.The coupling element for the projected slot according to the invention consists of a guide strip 1 approximately in the form of a strip and of at least one device mounted thereon, forming an injection channel extending over the entire length of the guide rail 1.
Vodilna letvica 1 je prednostno izoblikovana pločevinasto, to pomeni, da sestoji Iz t a n k o s t e n s k e g a ploskovnega materiala, ki ima kot pločevina določeno lastno togost. Ta vodilna letvica 1 v obliki traku ima dva dolga s t r a n s k a vzdolžna robova la, z g o r* n j i in spodnji prečni rob Ib in dve p o v r* š i n i vodilnih letvic, omejeni z robovi la, Ib.The guide strip 1 is preferably formed of sheet metal, that is, it consists of a sheet material having a certain rigidity as a sheet. This strip-shaped guide strip 1 has two long s t r a n s k a longitudinal edges la, with g o r * n j i and a lower transverse edge Ib, and two p o v r * š i n i leading rails bounded by the edges la, Ib.
Naprava, ki tvori kanal za vbrizganje 2, je lahko običajen kanal za vbrizganje ali pa sestoji iz tesnilne priprave s profilom, odprtim v preseku, izoblikovanim v obliki pokrova, ki je nameščen s prostimi vzdolžnimi robovi svojih stranskih območij nasedajoče na površini vodilne letvice le. Posebno ugodno je kot naprava, ki tvori kanal za vbrizganje 2, lahko izoblikovan nek trak penaste snovi 12 iz penaste snovi z odprtimi celicami oz. odprtimi porami.The device forming the injection duct 2 may be a conventional injection duct or may consist of a sealing device with a profile open in cross-section shaped like a cover arranged with the free longitudinal edges of its lateral areas adjacent to the surface of the guide strip only. Particularly advantageously, as a device forming an injection channel 2, a strip of foamed substance 12 may be formed from open-cell foam material or. open pores.
Vodilna letvica 1 ima prednostno nekaj manjšo Širino, kot je debelina stene od stene, ki jo je treba betonirati, tako da se lahko ta vbetonira z odmikom od 1 do nekaj centimetrov od zunanje površine stene, Presek se lahko tudi zmanjša v kombinaciji z od zunaj na površini stene speljanimi trikotnimi letvicami. Dolžina vodilne letvice 1 naj bi ustrezala približno višini stene, tako da se vodilna letvica 1 lahko pred betoniranjem postavi na odsek tal 3 talne plošče in se razteza do zgornje meje stene, ki jo je treba betonirati.Guide lath 1 preferably has a slightly smaller width than the thickness of the wall from the wall to be concreted, so that it can be concreted with a distance of 1 to a few centimeters from the outer surface of the wall, the cross-section can also be reduced in combination with the outside triangular slats on the wall surface. The length of the guide bar 1 should correspond approximately to the height of the wall so that the guide bar 1 can be placed on the floor section 3 of the floor slab before concreting and extends to the upper border of the wall to be concreted.
Penasta snov 12 ima prednostno nek približno pravokoten presek, pri čemer naj bi bila površina preseka le-te izbrana tako, da se penasta snov ne more stisniti skupaj nepropustno za material za injektiranje zaradi sosednjega betona in ta naj ne bo prevelika, da volumen, ki ga je treba izpolniti z materialom za injektiranje, držimo majhen. Pri kanalih za vbrizganje s prevelikim presekom obstoji poleg tega nevarnost, da se pri večjih netesnostih pri vbrizganju tesnilnegaThe foam material 12 preferably has an approximately rectangular cross-section, the cross-sectional area of which is to be selected such that the foam material cannot be compressed together to be impermeable to the injection material due to the adjacent concrete, and this volume should not be too large so that it should be filled with injection material, keep small. In the case of oversized injection ducts, there is also the risk that the sealing of the sealing may be more severe

Penasta snov 12 je prednostno penasta snov z odprtimi celicami, ki sestoji iz togega materiala iz umetne snovi, tako da ima penasta snov 12 določeno lastno togost.The foam 12 is preferably an open-cell foam consisting of rigid plastic material such that the foam 12 has a certain rigidity of its own.
Vodilna letvica 1 je prednostno opremljena s perforacijo 5 v območju stika s penasto snovjo 12 tako, da vbrizgan tesnilni material lahko prodre skozi vodilno letvico 1.The guide strip 1 is preferably equipped with a perforation 5 in the area of contact with the foam material 12 so that the injected sealing material can penetrate through the guide strip 1.
Na obeh straneh vodilne letvice 1 oz. obeh površinah vodilne letvice lc sta lahko tudi predvidena trakova penaste snovi 12 tako, da se tvorita na obeh straneh pločevine 1 kanala za vbrizganje 2. Oba trakova penaste snovi 12 ne smeta medseboj stati v povezavi, toda perforacija 5 v pločevini 1 med trakovoma penaste snovi omogoča izenaCevanje tlaka pri vbrizganju tesnilnega materiala in dovoljuje, da se izberejo površine presekov oz. debelina trakov iz penaste snovi manjše, ker se lahko lokalno oviranje funkcije traku iz penaste snovi 12 kompenzira skozi paralelno potekajoči kanal na drugi strani pločevine. Trak oz. trakovi iz penaste snovi 12 so prednostno nameščeni preCrio-središCno na površinah vodilnih letvic lc.On both sides of the guide strip 1 oz. both surfaces of the guide strip lc may also be provided with strips of foam material 12 such that they form on both sides of the sheet 1 of the injection channel 2. The two strips of foam material 12 may not be interconnected, but the perforation 5 of the sheet 1 between the strips of foam material allows equalization of pressure when injecting the sealing material and permits the selection of cross-sectional areas and / or joints. the thickness of the foam strips is smaller because the local hindrance of the foam strip 12 function can be compensated through a parallel channel running on the other side of the sheet. Ribbon or. foam strips 12 are preferably positioned pre-centrally on the surfaces of the guide strips 1c.
Tako se s predvidenjem perforacije 5 in enega samega traku penaste snovi kot priprave za oblikovanje kanala za vbrizganje 2, kot tudi s predvidenjem dveh trakov penaste snovi 12, zagotovi, da se zatesnita dve vodni poti vzdolž obeh površin vodilnih letvic lc.Thus, by providing perforation 5 and a single strip of foam material as a device for forming the injection duct 2, as well as providing two strips of foam material 12, it is ensured that two waterways are sealed along both surfaces of the guide strips 1c.
Naprava, ki tvori kanal za vbrizganje 2, je lahko nameščena tudi na enem od stranskih vzdolžnih robov la vodilne letviceThe device forming the injection channel 2 may also be mounted on one of the side longitudinal edges 1a of the guide strip

Vodilna letvica 1 je t a n k o s t e n s k i element, ki je lahko izoblikovan iz umetne snovi ali iz kovine. Spoj med trakom penaste snovi 12 in vodilno letvico 1 se prednostno izdela z lepljenjem.Guide rail 1 is a t a n k o s t e n s k i element that can be made of plastic or metal. The joint between the foam strip 12 and the guide strip 1 is preferably made by gluing.
Vodilna letvica 1 je bodisi plošCat element (Fig. 1 in 2) ali je lahko tudi opremljena s konturo (Fig. 3 in 4) z namenom, da bi se trak iz penaste snovi 12 v njej vključil deloma ali popolnoma. Zaradi svoje konture ima vodilna letvica 1 večjo togost in nudi penasti snovi zaščito proti tlaku zidu 4, ki nastopi zaradi sosednjega betona, ker so boki oz. stranske ploskve 8 penaste snovi in ena od obehThe guide strip 1 is either a flat element (Figs. 1 and 2) or may also be provided with a contour (Figs. 3 and 4) in order to integrate the foam strip 12 in part or in its entirety.

Montaža spojnega elementa za projektirano rego v smislu izuma poteka z vnašanjem spoj n ega elementa za projektirano rego v območje opaža stene, ki jo je treba betonirati. Spojni element za projektirano rego se pri tem postavi na betonsko plošCo, na katero naj bi se betonirala stena, pri Čemer naj vodilna letvica 1 stoji približno pravokotno na stranske površine zidu 4, ki ga je treba betonirati. Po postopku betoniranja se v tesnilni kanal, ki se tvori s trakom iz penaste snovi 12, vbrizga tesnilni material, ki potem v izobilju izpolne spoj za projektirano rego, oblikujoč se pri procesu vezanja. Vbrizganje tesnilnega materiala se lahko vrši potem, ko je bil na steni 4, z v njej vloženim spojnim elementom za projektirano rego, nanešen nadaljnji odsek 11, ki kanal za vbrizganje 2 zatesni navzgor. Kanal za vbrizganje 2 se nato od zunaj navrta in skozi izvrtino 10 seThe mounting of the coupling element for the projected lug according to the invention is carried out by inserting the coupling element for the projected lug into the paneling area of the wall to be concreted. The coupling element for the projected joist is then placed on the concrete slab on which the wall is to be concreted, whereby the guide rail 1 is approximately perpendicular to the side surfaces of the wall 4 to be concreted. Following the concreting process, a sealing material is injected into the sealing duct formed by a strip of foam material 12, which then in abundance fills the joint for the projected lug formed during the bonding process. Injection of the sealing material may be carried out after a wall section 4 has been inserted therein with a projecting lug inserted therein, a further section 11 is applied which seals the injection channel 2 upwards. Injection duct 2 is then threaded from the outside and through the bore 10

Na ugoden način se lahko spojni element za projektirano rego v smislu izuma uporablja tudi z vodilno letvico 1 in na to nameščenim trakom 12 iz penaste snovi v povezavi z nabrekljivim trakom 6 (Fig. 5 in 6). Nabrekljivi trak 6 je treba namestiti vsaj na eni strani, prednostno na obeh straneh vodilne letvice 1 ali na stranskem vzdolžnem robu la vodilne letvice 1 preko celotne dolžine vodilne letvice. Po dokončanju se pokaže, Ce nabrekljivi trak zagotavlja potrebno tesnost v spoju za projektirano rego 7. če bi bi bilo to, lahko naknadno vbrizganje tesnilnega materiala opustimo, če pa bi se pokazale še naknadne netesnosti, se lahko ob vsakem Času z navrtanjem kanala za vbrizganje 2 vbrizga tesnilni material in se netesni spoj za projektirano rego zatesni. Naknadno vbrizganje tesnilnega materiala poteka z navrtanjem kanala za vbrizganje in z vbrizganjem tesnilnega materiala. Z uporabo nabrekljivih trakov torej ne nastane nikakršen rizik, ker se tesnost lahko vedno naknadno ponovno vzpostavi. To omogoča tudi, da se uporabljajo nabrekljivi trakovi 2 relativno manjšo debelino, ki v večini primerov nudijo zadostno tesnost. S tem so stroški pri uporabi relativno dragih nabrekljivih trakov omejeni, kar v povezavi s stroškovno ugodno penasto snovjo v primerjavi z nabrekljivim trakom nudi vse skupaj poceni rešitev problema, ne da bi obstojal rizik netesnega spoja za projektirano rego, ki ga naknadno ne bi mogli zatesniti.In an advantageous manner, the coupling element for the projected sling according to the invention can also be used with the guide strip 1 and the foam material strip 12 fitted therewith in conjunction with the swelling strip 6 (Figs 5 and 6). The swellable strap 6 should be positioned on at least one side, preferably on either side of the guide rail 1 or on the longitudinal longitudinal edge 1 of the guide rail 1 over the entire length of the guide rail. When complete, it is shown that if the swelling tape provides the necessary tightness in the joint for the projected track 7. If this is the case, subsequent injection of the sealing material can be omitted, or if further leaks are found, the injection channel can be turned at any time. 2 injects the sealing material and seals the sealed joint for the designed reg. Subsequent injection of the sealing material is done by drilling the injection duct and injecting the sealing material. Thus, the use of swollen tapes does not create any risk, since the tightness can always be subsequently restored. This also makes it possible to use swollen webs 2 of relatively smaller thickness, which in most cases offer sufficient tightness. This reduces the cost of using relatively expensive swell strips, which, combined with the cost-effective foam compared to the swollen strap, offers an inexpensive solution to the problem without the risk of a leaky joint for the projected reggae, which cannot subsequently be sealed. .

2.2.
Nadaljnja ugodna izvedba je vodilna letvica 1, ki ima votel kanal za vbrizganje 2, ki je popolnoma obdan z dvema stranskima in eno sprednjo in zadnjo steno 16, 17, 18, 19 vodilne letvice 1 in oddaja tesnilni material preko perforacije 5 navzven (Fig. 7 in 8). Votli kanal za vbrizganje 2 se lahko bodisi izpolni s trakom penaste snovi 12 ali se lahko odprtine perforacije 5 zatesnijo pred vdiranjem betona v postopku betoniranja s koprenastim materialom ali materialom iz penaste snovi ali podobnim, ki je za tesnilni material prepusten. Odprtine perforacije 5 so lahko narejene tudi na stranskih površinah kanala za vbrizganje 2, pri čemer lahko izberemo njihovo namestitev in velikost v skladu z uporabljenimi tesnilnimi materiali in uporabljenim betonom. Vendar je potrebno, da lahko tesnilni material izstopa na obeh straneh vodilne letvice 1, s Čimer je zagotovljeno, da se spoj za projektirano rego s procesom vbrizganja popolnoma zatesni.Another advantageous embodiment is a guide strip 1 having a hollow injection channel 2 which is completely surrounded by two lateral and one front and rear walls 16, 17, 18, 19 of the guide rail 1 and transmits the sealing material through the perforation 5 outwards (Figs. 7 and 8). The hollow injection duct 2 can either be filled with a strip of foam material 12 or the perforation openings 5 may be sealed before concrete penetration by concreting with a foam or foam material or the like which is permeable to the sealing material. The holes of the perforation 5 can also be made on the side surfaces of the injection channel 2, whereby their placement and size can be selected according to the sealing materials used and the concrete used. However, it is necessary that the sealing material can protrude on either side of the guide rail 1, thereby ensuring that the joint for the projected lug is completely sealed by the injection process.
Namesto traku iz penaste snovi se lahko kot naprava, ki tvori kanal za vbrizganje, uporabi tudi običajna cev za vbrizganje. Pri uporabi običajne cevi za vbrizganje s krožnim presekom je treba prednostno uporabiti dve cevi za vbrizganje na obeh straneh vodilne letvice ali izoblikovati luknje perforacije kot dolge luknje, tako da je poskrbljeno za zadosten prepust za tesnilni material skozi vodilno letvico.Instead of a foam strip, a conventional injection tube may also be used as a device forming an injection channel. When using a conventional circular cross-section injection pipe, it is preferable to use two injection tubes on either side of the guide rail or to form perforation holes as long holes so that sufficient sealing material is passed through the guide rail.
če naj bi bila na vodilni letvici 1 s perforacijo nameščena samo ena cev za vbrizganje 13, se lahko prednostno uporabi tudi cev za vbrizganje, ki sestoji iz cevastega dela 14 in osnove 15 v obliki traku, pri Čemer je osnova 15 nanesena na območju perforacije 5 vodilne letvice 1 (Fig. 10 in 11). Osnova 15 je opremljena z izstopnimi odprtinami za tesnilni material. To je novo v primerjavi z običajnimi cevmi za vbrizganje z osnovnim trakom, pri katerih je osnovni trak sluzil samo kot fiksirni element za lažje nameščanje cevi za vbrizganje na območje, ki ga je treba zatesniti. S tako razporeditvijo se zagotovi, da v cev za vbrizganje 13 vbrizgani tesnilni material izstopa tako iz cevi v območje betona, ki obdaja cev, kot tudi preko osnovnega traku 15, ki sestoji prednostno iz istega materiala kot del cevi 14 in skozi luknje perforacije 5 dospe na drugo stran vodilne letvice 1, da bi tam zatesnil nastopajoča prosta mesta.if only one injection tube 13 is to be mounted on the perforation guide strip 1, then an injection tube consisting of a tubular portion 14 and a ribbon-shaped base 15 may be used, whereby the base 15 is applied in the area of the perforation 5 guide slats 1 (Figs. 10 and 11). The base 15 is provided with outlets for sealing material. This is new compared to conventional injection tubes with a base tape, in which the base tape only served as a fixing element for easier placement of the injection tubes in the area to be sealed. This arrangement ensures that the injection tube 13 injected sealing material protrudes from the pipe into the area of concrete surrounding the pipe as well as through the base strip 15, which consists preferably of the same material as the pipe section 14 and reaches through the perforation holes 5. to the other side of the guide rail 1 to seal the vacant positions there.
Na Fig. 12 je prikazana nadaljnja izvedba spojnega elementa za projektirano rego v smislu izuma v preseku.In Figs. 12 shows a further embodiment of the coupling element for the projected reg in the sectional view of the invention.
Vodilna letvica 1 tega spojnega elementa za projektirano rego je simetrično izoblikovana okoli prečno-središčne osi 20. Na prečni sredini vodilne letvice 1 je nameščena naprava za oblikovanje kanala za vbrizganje, ki je razdeljena na tri območja, nek središčen votel kanal 2a in dva stranska trakova iz penaste snovi 12, ki vsakokrat tvorita neko delno območje 2b kanala za vbrizganje. Votli kanal 2a ima pravokoten presek in je omejen z dvema stranskima stenama 21 in z eno zgornjo in spodnjo steno 22,23. Stranske stene 21 so nameščene z majhnim razmakom druge proti drugi, ki ustreza približno debelini materiala pločevinastega materiala vodilne letvice 1.The guide bar 1 of this coupling element for the projected reg is formed symmetrically about the transverse-center axis 20. In the transverse center of the guide strip 1 is a device for forming an injection channel, which is divided into three areas, a central hollow channel 2a and two side strips of foam material 12, which each form a partial area 2b of the injection channel. The hollow channel 2a has a rectangular cross-section and is bounded by two side walls 21 and one upper and lower walls 22,23. The side walls 21 are mounted at a small distance from each other, corresponding to approximately the thickness of the sheet material of the guide strip 1.
Zgornja in spodnja stena 22,23 se raztezata na obeh straneh preko stranskih sten 21 navzven, tako da zgornja in spodnja stena 22, 23 tvorita s stranskimi stenami 21 stransko odprte utore za vključenje trakov iz penaste snovi. V obeh stranskih stenah 21 so predvidene odprtine za perforacijo 5, tako da stoji votli kanal 2a s trakovi iz penaste snovi 12 v komunicirajoči povezavi. Odprtine so v stranskih stenah 21 lahko nameščene zamaknjeno, tako da presek vodilne letvice 1, pokazan na Fig. 12, sega samo v desni stranski steni 21 skozi odprtino perforacije 5,The upper and lower walls 22,23 extend on both sides beyond the side walls 21 to the outside so that the upper and lower walls 22, 23 form side-open grooves with the side walls 21 to engage the foam strips. Perforation openings 5 are provided on both side walls 21 such that a hollow channel 2a with foam strips 12 in communication communication is provided. The openings in the side walls 21 may be positioned offset so that the cross section of the guide strip 1 shown in FIG. 12, extends only in the right side wall 21 through the perforation opening 5,
Za ojačitev spojnega elementa za projektirano rego je vodilna letvica 1 opremljena z ojačilnimi robovi 24, ki so vsakokrat izoblikovani z robovi, vezanimi pravokotno na površinah vodilne letvice lc, ki se raztezajo preko celotne dolžine vodilne letvice 1.To reinforce the coupling element for the projected reg, the guide strip 1 is provided with reinforcing edges 24, which are each formed by edges tied perpendicularly to the surfaces of the guide rail lc, extending over the entire length of the guide rail 1.
Ojacilni robovi 24 dosežejo tudi podaljšanje vodne poti v projektirani regi, tako da se z njimi ne izboljša samo togost vodilne letvice 1, ampak se doseže tudi boljša tesnost .The reinforcing edges 24 also achieve a lengthening of the waterway in the projected region, which not only improves the rigidity of the guide bar 1 but also improves the tightness.
