Abstract

Vynález sa týká tesniaceho dilatačného pásu pre betonové konštrukcie. Podstatou vynálezu je, že po okraji pásu sú vytvořené dutiny opatřené perforáciou, prostredníctvom ktorej sa primárné indikuje obtekanie tesniaceho pásu a sekundárné umožňuje privedenie injekčného média priamo do poréznej časti dilatácie betonovej konštrukcie· Použitie je možné predovšetkým vo vodohospodárskej výstavbě.The invention relates to a sealing expansion joint strip for concrete structures. The essence of the invention is that cavities are formed along the edge of the strip, provided with perforations, through which the primary flow around the sealing strip is indicated and the secondary one enables the injection medium to be introduced directly into the porous part of the expansion joint of the concrete structure. It is used primarily in water management construction.

Vynález sa týká tesniaceho dilatačného pásu, použitelného pre betonové konštrukcie.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing expansion strip useful for concrete structures.

Doteraz známe tesniace dilatačně pásy sa vyznačujú róznym tvarováním, ktoré umožňuje spolehlivé kotvenie, vyrovnanie tahového namáhania a osadenia debnenia. V tuzemsku sa vyrába len jeden typ tesniaceho dilatačného pásu na báze pryže, ktorý sa vžak vyznačuje velkou Šířkou a tým aj hmotnosfou, čo má negativny vplyv na manipuláciu. Najnovšie typy tesniacich pásov v zahraničí sú lahšej konštrukcie na báze plastov. 'Up to now known expansion dilatation strips are characterized by a rosa-forming design that allows for reliable anchoring, tensile stress compensation and formwork mounting. Only one type of rubber expansion strip is produced in the country, but is characterized by a large width and hence weight, which has a negative effect on handling. The latest types of sealing tapes abroad are lighter in plastic-based construction. '

Spoločným nedostatkom doteraz známých tesniacich dilataČných pásov je obtekanie tesniaceho elementu vplyvom poréznosti betonu, ktorý móže vzniknut aj pri dodržaní technologickéj discipliny a uviaznutím vody a vzduchu v priestore lemovania pásu pri spracuvávapí čerstvej betónovej zmesi· Defekty sa spravidla zistia až po uvedení stavebného diela do prevádzky a náklady na dodatočnú sanáciu sú velmi vysoké. Přitom používané spósoby oprav nie sú v súlaďe so základnými požiadavkami kladenými na funkciu dilatácie. Často je aj opakované odstraňovanie priesakov bez efektu.The common drawback of the hitherto known sealing expansion strips is the bypass of the sealing element due to the porosity of the concrete, which can also be produced by keeping the technological discipline and by stuck water and air in the stripping area of the fresh concrete mixture. the costs of additional rehabilitation are very high. The repair methods used here are not in line with the basic requirements for the dilatation function. Often there is also repeated removal of leaks without effect.

Vyššie uvedené nedostatky sú odstránéné tesniacim dilatačným pásom s pozdížne umiestnenými výstupkami a dutinami podlá vynálezu, ktorého podstata spočívá v tom, že na okraj.och sú vytvořené dutiny, opatřené perforáciou.The aforementioned drawbacks are eliminated by a sealing expansion strip with longitudinally extending projections and cavities according to the invention, the principle of which is that perforations are provided on the edges.

Perforované dutiny majú primárnu funkciu indikovat a lokalizovat případné obtekanie tesniaceho dilatačného pásu. Za tým účelom sa podlá potřeby okrajové perforované dutiny vyvedú z betónovej konštrukcie do priestorov umožňujúcich kontrolu vizuálnu, popřípadě električku. V případe netěsnosti dilatácie, spravidla vinou nekvality betonu v tesnej blízkosti dilatačného pásu, je sekundárnou funkciou perforovaných okrajových dutin privedenie- injekčnej zmesi priamo do poréznej Časti betónovej konštrukcie.The perforated cavities have a primary function to indicate and locate the possible bypass of the sealing expansion strip. To this end, the peripheral perforated cavity is led out of the concrete structure to the visual inspection or tramway control areas. In the event of a dilatation leak, generally due to the poor quality of the concrete in close proximity to the expansion strip, the secondary function of the perforated marginal cavities is to inject the injection mixture directly into the porous concrete structure.

Na pripójenom výkrese je znázorněný příklad prevedenia tesniaceho dilatačného pásu podlá vynálezu, kde na obr. 1 je nakreslený pás v řeze A-A, na obr. 2 je nakreslený pás v náryse.In the accompanying drawing, an exemplary embodiment of a sealing expansion strip according to the invention is shown, wherein in Fig. 1 a strip is drawn in section A-A, in Fig. 2 the drawn strip is in front view.

Tesniaci dilatačný pás je opatřený poz dl žne umiestnenými výstupkami 1, ktoré zvyšujú primárnu tesniacu funkciu a okrajovými dutipami 2^ s perforáciou 3, prostredníctvom ktorej je možné indikovaf netesnosé betonu a priviesf injekčhú zmes priamo do poréznej časti dilatácie, Středná dutina umožňuje dížkovú změnu pásu v dilatácii a rebro 5. uchytenie pásu do debnenia.The sealing expansion strip is provided with longitudinally extending protrusions 1, which increase the primary sealing function and the peripheral hollows 2 'with the perforation 3, through which concrete leakage can be indicated and the injection mixture is brought directly into the porous portion of the dilatation. dilatation and rib 5. attachment of the belt to the formwork.

Tesniaci dilatačný pás je možné vyrobit například z mákčeného PVC za podstatného zníŽenía hrubky, šířky a tým aj hmotnosti v porovnaní s doterajšími dilatačnými pásmi. .The sealing expansion strip can be made, for example, of PVC dipped with a substantial reduction in roughness, width and hence weight compared to the existing expansion strips. .
