Abstract

The solution concerns a set for vertical socket joins of concrete support grouted with thermite steel. The set consists of a prefabricated single shot feed runner (3), which is mounted on a tube (2) into a feeding hole of a socket (1), on which a vertical two-part feed runner (4) is mounted, supported by a console (7). It is pressed by a press (8) to the socket (1). In mouth (9) of the vertical feed runner (4) there is a prefabricated plate (10), on which there is a remelting plate (11). Above the vertical two-part feed runner (4) there is a reaction graphite crucible (12) equipped with a cover (14). The set is suitable for preparation of a concrete support in assembly conditions. Ultimate tensile strength of the socket join equals the rigidity of a non-compounded concrete support and even unweldable concrete steel can be compounded.<IMAGE>

Description

Vynález 3a týká súpravy pre vertikálna objímkové spoje betonárskej výstuže zalievané termitovou ocelou.The invention 3a relates to a kit for vertical sleeve joints of concrete reinforced with thermite steel.

Súprava pre vertikálně zalievanie objímkových spojov betonárskej výstuže s volným nastavením bez medzier a v prefábrikácii je v zahraničí známa. Reakčný téglik je vyhotovený z grafitovej rúrky, na ktorú sa ešte nastavuje kovová rúrka. Po reakcii musí sa tekutá troska z téglika zavčasu vylievat, čo je obtíažna operácia.The set for vertically watering the clamp joints of the concrete reinforcement with free adjustment without gaps and in prefabrication is known abroad. The reaction crucible is made of a graphite tube on which a metal tube is still set. After the reaction, the liquid slag must be poured out of the crucible in a timely manner, which is a difficult operation.

Dvojdielny grafitový liaci kanálik je konstruovaný ako jednoúčelový s válcovitou dosadacou plochou v ústi podía priemeru zalievanej objímky, ku ktorej sa pritláča pomocou gallovej reíaze s excentom, čo stažuje manipuláciu při montáži.The two-piece graphite casting channel is designed as a single-purpose with a cylindrical bearing surface in the mouth according to the diameter of the sealed sleeve to which it is pressed by an eccentric gauge chain, which makes assembly handling difficult.

Uvedené nevýhody sú do značnej raiery odstránené súpravou pre vertikálně objímkové spoje betonárskej výstuže zalievané termitovou ocelou podía vynálezu, ktorá je tvořená reakčným grafitovým téglikom, ktorého dno tvoří centrovacia platnička, podstata ktorej spočívá v tom, že Sálej pozostáva z dvojdielneho liaceho kanálika z grafitu opatřeného ústím pre odtok termitovej ocele.These drawbacks are eliminated to a considerable extent by the termite steel-embedded vertical sleeve jointing kit of the invention, which consists of a reaction graphite crucible, the bottom of which is a centering plate, which consists of a two-piece casting channel made of graphite orifice. for termite steel drain.

Súprava pre vertikálně objímkové spoje betonárskej výstuže zalievané termitovou ocelou podlá vynálezu umožňuje v montážnych podmienkach stavby vyhotovoval vertikálně objímkové spoje o takej pevnosti v ňahu, akú má nespojovaná výstuž. konce výstuže sa možu v objímke spojovat bez medzere alebo s medzerou medzi koncami do velkosti priemeru spojovacej výstuže. Troska v reakčnom tégliku po vychladnutí sa lahko odstráni z kuželových stien téglika.The set for vertically sleeve joints of concrete reinforced with thermite steel according to the invention makes it possible in the assembly conditions of the construction to produce vertically sleeve joints with the tensile strength of unconnected reinforcement. the ends of the reinforcement can be joined in the sleeve without a gap or with a gap between the ends up to the diameter of the connecting reinforcement. The slag in the reaction crucible, upon cooling, is easily removed from the conical walls of the crucible.

Kuželový liaci kanálik nasadený na objímke je rotačný, čo umožňuje dvojdielnemu lincemu kanáliku pootočenie pracovnej polohy a možu sa vyhotovit vertikálně spoje i nakloněné do 3Q°« Při súčasnom nastavovaní zvislej výstuže možu sa vertikálně súpravy nastavit do série vedla seba a zhotovit viac spojov naraz.The tapered casting channel mounted on the sleeve is rotatable, allowing the two-piece inline channel to rotate the working position and can make vertical joints inclined up to 3 °. At the same time adjusting the vertical reinforcement, the vertical sets can be aligned side by side and make multiple joints at once.

Na priloženom obrázku je znázorněná vertikálna súprava v řeze.The attached figure shows a vertical set in section.

Vynález je bližšie objasněný na nasledovnom příklade. Po liaceho otvoru objímky sa vsunie ocelová rúrka 2, na ktorú sa nasunie prefabrikovaný kuželový liaci kanálik 3· Dvojdielny liaci kanálik z grafitu 4 sa uzavrie pomocou pantografu. 5, uzamkne sa poistkou 6, nasunie sa kuželovým výtokovým kanálikom na prefabrikovaný liaci kanálik 3 a podoprie sa na predom přimontovaná nastavovaciu konzolu 7 do zvislej polohy. Pomocou skrutkového lisu 8 přitlačí sa dvojdielny liaci kanálik 4 s prefabrikováním k objímke J., čím sa utěsní liaci systém. Naď ústie dvojdielneho liaceho kanálika 9 vloží sa centrovacia platnička £0, ktorá tvoří dno reakčného grafitového téglika 12, nad ktorú sa umiestni pretavovacia platnička z ocele a reakčný téglik 1.2 sa postaví na dvojdielny liaci kanálik 4 tak, aby zakryl centrovaciu platníčku 1.0. Do reakčného grafitového téglika Γ2 sa vsype zalievková aluminotermická dávka 13, ktorá sa zapaluje aluminotermickou zápalkou a téglik 12 sa přikryje poklopom 14. Po reakcii vyredukovaný kov přetaví ocelovú platničku 1.1 a tečie liacim kanálikom 9 do objímky J., kde sa po stuhnutí kovu v objímke J vytvoří pevné a spolahlivé spojenie kovov výstuže.The invention is illustrated by the following example. A steel tube 2 is inserted over the casting hole of the sleeve, onto which the prefabricated conical casting channel 3 is inserted. The two-part casting channel of graphite 4 is closed by means of a pantograph. 5, it is locked by a fuse 6, pushed onto the prefabricated casting channel 3 by means of a conical outlet channel and supported on a pre-mounted adjusting bracket 7 in a vertical position. By means of a screw press 8, the two-part casting channel 4 is pre-fabricated to the sleeve J, thereby sealing the casting system. At the mouth of the two-part casting channel 9 a centering plate 60 is inserted, which forms the bottom of the reaction graphite crucible 12, over which a steel remelting plate is placed and the reaction crucible 1.2 is placed on the two-part casting channel 4 to cover the centering plate 1.0. Into the reaction graphite crucible Γ2 a pouring aluminothermal dose 13 is placed which is ignited by an aluminothermal match and the crucible 12 is covered with a lid 14. After the reaction, the reduced metal melts the steel plate 1.1 and flows through the pouring channel 9 into the socket. J forms a firm and reliable connection of the reinforcement metals.

Súprava podía vynálezu zabezpečuje dobré zalievanie konca výstuže v objímke, kde vznikne nerozoberatelné, spolahlivé a pevné spojenie.The kit according to the invention ensures good watering of the end of the reinforcement in the sleeve, where a non-detachable, reliable and firm connection is formed.

Pevnosň v íahu objímkového spoja sa vyrovná pevnosti nespojovanej betonárskej výstuže a spojovaň sa možu i nezvaritelné betonářské ocele, lebo teplo zalievkového kovu nestačí nepriaznivo ovplyvnií vlastnosti spojovacích materiálov.The tensile strength of the sleeve joint is equal to that of the unbonded concrete reinforcement, and even non-weldable reinforcing steels can be joined because the heat of the casting metal is not sufficient to adversely affect the properties of the bonding materials.
