Description
Vynález se tyká otevrené hmoždinky pro pražoe z predpratého betónu, vyrábéné prdbéžným pracovním postupem.The present invention relates to open dowels for pre-washed concrete dowels produced by a conventional process.
iepiyiiky hmoždinky z umelé hmoty, určené pro ukotvení upevňovacích šroubú k olej nie v betónových praŽcích jsou známy· Hmoždinky pre pražce z predpjatého betónu, vyrábéné prubéžným pracovníci postupem (napríklad pro pražce Abetong), marí nzaviený tvar. Hmoždinka se do betónu zalévá a dosahuje približne až do 2/3 výšky pražce» Aby se zabránilo nashŕomáždéní vody ve hmoždince béhem dopravy, pri skladovaní nebo stavenlsti, opatrí se hmoždinka svnitf vrstvou tuku (Terrecete) nebo tésnicími pysky. Obé opatrení vyžaduj dodatečné pracovní a materiálové náklady* Presto se však podie zkušeností nedosáhne absolútni tesnosti hmoždinky. Voda, která vnikne do hmoždinky,, muže pri zmrznutí zepríčinit vznik trhlín nebo dokonca prasknutí pražce.Plastic dowels intended for anchoring fastening bolts to oil not in concrete roasters are known. The dowel is poured into the concrete and reaches up to approximately 2/3 of the sleeper height. Both measures require additional labor and material costs * However, experience has shown that the anchor is not leakproof. Water entering the dowel can cause cracks or even sleepers to burst when frozen.
Pále je také známa otevŕená hmoždinka, která se peuživá pro jednotlivé upínané betónové pražce. Hmoždinka j® v oblasti dna otevŕená. Hmoždinka se do betónu zalévá. Predtím se ale musí otvor ve dnu hmoždinky uzavíít, aby se zabránilo Vniknutí betónu.Also known is an open dowel which can be used for individual clamped concrete sleepers. The dowel is open in the bottom area. The dowel is watered into the concrete. Before that, the opening in the dowel bottom must be closed to prevent concrete from entering.
Po zatuhnutí betónu se uzáver (bednéní) složitým post upem vyjme nebo dokonce vyráží. Pro výrobu pražcd z predpratého betónu prúbéžnýa pracovním postupem se tento druh hmoždinek nehodí· ,pndstst^;:WRáiegu .·,After the concrete has set, the shutter (formwork) is removed or even punched out with a complicated post up. For the preparation of pražcd concrete prúbéžnýa prewashed according to the procedure, this type of anchors fit ·, s ^ n DSTS; : WRáiegu.
Úloha vynálezu spocívá ve vytvorení hmoždinky, která je vhodná pro výrobu pražeň z predpjatého betónu prôbéžjoýmSUMMARY OF THE INVENTION The object of the invention is to provide a dowel suitable for the manufacture of prestressed concrete roast
- 2 pracovním postupem. Tato úloha byla vyžezsuz tím, že dno hmoždinky je prodlouženo o kuželovou čepičkou a tato je opatrená dnem hmoždinky. Dno hmoždinky je tenkosténné, snadné k provrtání nebo proražení.- 2 working procedure. This task has been improved by the plug base being extended by a tapered cap and this plug is provided with a plug base. The dowel bottom is thin-walled, easy to drill or pierce.
Výhoda této hmoždinky oproti stávajícím hmožuinkáia spočíva v tom, že se ve hmoždince prakticky nemaže nashromáždit vode.The advantage of this dowel over existing dowels is that it is virtually impossible to collect water in the dowel.
Po dohotovení pražcú z pŕedpjatéhD betónu se dno hmoždinky prorazí nebo provrtá, čímž se ve hmoždince nemúžeuž shromažSovat voda. Hmoždinka je tak dlmenzována, že prochází celým pražcem. Dno hmoždinky zabraňuje tomu* aby pri betenování vnikl betón do hmoždinky. Kuželová čepička je däle výhodná tím, že se vnéjsí závit neprodlouží, čímž zústanouzachovány silové poméry jako u krátke hmoždinky, to znamená, že se nezméní odzkoušené poméry známe u krátke hmoždinky·After the sleepers have been made of prestressed concrete, the bottom of the dowel is pierced or drilled so that no water can collect in the dowel. The dowel is so dimensioned that it goes through the whole sleeper. The dowel bottom prevents the concrete from penetrating into the dowel during concreting. The tapered cap is further advantageous in that the external thread does not lengthen, thus maintaining the force ratios as in the case of the short plug, i.e. the tested conditions known in the short plug are not changed.
Príklad provedení vynáleznDETAILED DESCRIPTION OF THE INVENTION
Príklad provedení vynálezu je blíže vy svet len podie výkresu. Hmoždinka £ sestává z telesa £ hmoždinky, koruny £ hmoždinky a výbehu vnitíníh© závitu 2· Hm&ždihka X je prodlou žena čepíčkou £. Čepička X je pri pohledu zvnejska vytvorená kuželová, nemá žádný závit a není opatrená zebry. Vnitfní stena kuželové čepičky X je približne do poloviny valcová a od stredu vytvarována kužeľovité.DETAILED DESCRIPTION OF THE INVENTION The invention is illustrated in greater detail in the drawing. The dowel £ consists of the dowel body £, the dowel crown a and the internal thread thread 2. The cap X is conical when viewed from the outside, has no thread and no zebras. The inner wall of the conical cap X is approximately half cylindrical and conical in shape from the center.
Kuželová čepička £ je opatrená dnera £ hmoždinky. Dno £ hmoždinky je vytvorená tak, že je možno jej snadno provrtat nebo prorazit. Dno £ hmoždinky musí ale současné odolat tlaku, který je na nej vyvozován béhem betonování.The conical cap 6 is provided with an anchor dowel. The plug base 6 is designed so that it can be easily drilled or pierced. At the same time, the wall of the plug must withstand the pressure exerted on it during concreting.
Celá hmoždinka je vyrobená z umélohmotného materiálu, napríklad termoplastu.The entire dowel is made of a plastic material, for example a thermoplastic.
