Abstract

The solution concerns a set with deviation for horizontal socket join of a concrete support grouted by thermite steel. Its principle consists in the fact that it is composed of a prefabricated conical feed runner (3), which is mounted on a tube (2) into a feeding hole of a socket (1), on which a horizontal two-part graphite deviated feed runner (4) is mounted, which is pressed to the socket (1) by a press (8) and into whose mouth (14) of the two-part feed runner made of graphite a prefabricated centring plate (9) is slided. On this plate (9) a remelting plate (10) is positioned above the mouth, above the centring plate there is a reaction graphite crucible (11) equipped with a cover (13).<IMAGE>

Description

Vynález sa týká súpravy pre horizontálně objímkové spoje betonárskej výstuže zalievané termitovou, oceíou.The invention relates to a set for horizontal sleeve joints of concrete reinforced with thermite steel.

Súpravy pre horizontálně zalievanie objímkových spojov betonárskej výstuže volné nastavovanéj bez medzier sú známe. Beakčný téglik v súprave je vytvořený z grafitovej rúry, na ktorú sa nasúva kovový nátrubok. Po reakci sa tekutá troska z téglika vylieva, pričom táto operácia musí sa urobit v čase, kecL je ešte troska tekutá, čo je obtažná operácia.Kits for horizontally watering the joints of the concrete reinforcement loosely adjusted without gaps are known. The reaction crucible in the kit is formed from a graphite tube onto which a metal sleeve is pushed. After the reaction, the liquid slag is poured out of the crucible, and this operation must be performed at a time when the slag is still liquid, which is a difficult operation.

Dvojdielny grafitový liaci kanálik má len nepatrný odklon a nemože sa vsunut medzi husto ngpnTn a danú výstuž v radě nad sebou. MSže sa‘nasadzovat na objímku len v pozdížnom smere jej osi. Pre husto nastavovaná, betonársku výstuž nad sebou ako sa vyskytuje u nás, pri připojovaní aimoblokov alebo prefabrikácii sa takáto súprava použit nedá. Okrem toho súprava sa prichytáva na objímku gallovou retazou s excentrom, čo stažuje manipuláciu pri montáži.The two-piece graphite casting channel has only a slight deviation and cannot be inserted between the densely ngpnTn and the given reinforcement in a row above one another. MApply to the sleeve only in the longitudinal direction of its axis. For densely adjusted, concrete reinforcement one above the other, as it occurs in our country, when attaching aimoblocks or prefabrication, such a kit can not be used. In addition, the kit attaches to the collar with an eccentric gland chain, which makes assembly handling difficult.

Uvedené nevýhody sú do značnej miery odstránené súpravou s odklonom pre horizontálně zalievanie objímkových spojov betonárskej výstuže podía vynálezu. Podstata vynálezu spočívá v tom, že súprava je tvořená jednorázovým liacim kanálikom, ktorý je nasadený na rúrke do liaceho otvoru objímky, na ktorý je nasunutý horizontálny dvojdielny grafitový odkloněný liaci kanálik, ktorý je lisom pritláčaný k objímke a do ktorého v ústi je zasunutá centrovacia prefabrikovaná platnička, na ktorú je položená pretavovacia platnička nad otvorom dvojdielneho grafitového odkloněného liaceho kanálika a nad centrovacou platničkou je reakčný grafitový téglik opatřený poklopom.These drawbacks are largely eliminated by the diversion kit for horizontal embedding of the clamp joints of the concrete reinforcement according to the invention. SUMMARY OF THE INVENTION The kit consists of a disposable casting channel which is mounted on a tube in the casting hole of the sleeve, onto which a horizontal two-piece graphite diverting channel is inserted, which is pressed by the press against the sleeve and into which a centering prefabricated a plate on which the removable plate is placed above the opening of the two-piece graphite diverting channel and above the centering plate is a reaction graphite crucible provided with a lid.

Súprava s odklonom pre horizontálně objímkové spoje betonárskej výstuže zalievané termitovým kovom podía vynálezu umožňuje v montážnych. podmienkach v hustom usporiadaní výstuže nad sebou vyhotovoval spoje zalievané termitovou oceíou o takej pevnosti v tahu, akú má nespojovaná výstuž. Spájat sa možu konce výstuže bez medzery a s medzerou do velkosti priemeru spájanej výstuže. Troškové zvyšky v reakčnom téglika z kuželových stien sa po vychladnutí íahko odstránia.The diversion kit for the horizontal sleeve joints of the concrete reinforced with thermite metal according to the invention allows for assembly. under the dense arrangement of the reinforcement one above the other, he made thermite-steel joints of the tensile strength of the unbonded reinforcement. The ends of the reinforcement can be joined without a gap and with a gap up to the diameter of the connected reinforcement. The traces of residue in the crucible are easily removed from the conical walls.

Cez zapuštěný prefabrikovaný kuželový liaci kanálik, ktorý je rotačný, može sa zalievat vo vodorovnej polohe s íubovoíným nastavením dvojdielneho liaceho kanálika v uhle od 0 do 360°.Through the recessed prefabricated conical casting channel, which is rotatable, it can be cast horizontally with any adjustment of the two-piece casting channel at an angle of 0 to 360 °.

Na pripojenom obrázku je súprava s odklonom pre horizontálně-zalievanie objímkových, spojov betonárskej výstuže znázorněná v řeze.In the attached figure, the diversion set for horizontal-potting of the clamp joints of the concrete reinforcement is shown in section.

Do liaceho otvoru objímky 2 je vsunutá ocelová rúrka 2, na ktorú sa nasunie prefabrikovaný kuželový liaci kanálik 3· Dvojdielny liaci kanálik z grafitu 4 sa uzatvára pomocou pantografu 5, uzamkne sa poistkou 6, nasunie sa kuželovým výtokovým kanálikom na prefabrikovaný liaci kanálik 3 a podoprie sa na vopred přimontovánu nastavovaciu konzolu 7 do vodorovnej polohy. Pomocou skrutkového lisu 8 přitlačí sa dvojdielny liaci kanál i k 4 k objímke 2» čím sa utěsní liaci systém. Do ústia 24 dvojdielneho liaceho kanálika 4 vloží sa centrovacia platnička 9, na ktorú sa položí ocelová pretavovacia platnička 10 nad hlavný vtokový otvor. Beakčný téglik 22 j© postavený na dvojdielny liaci kanálik 4 tak, aby zakryl centrovaciu platničku 9. Aluminotermická dávka 12. vsypaná do reakčného téglika 22, sa zapaluje aluminotermickou zápalkou a tento sa přikryje poklopom 22· Po reakcii vyredukovaný kov přetaví oceíovú platničku 22 a vtečie ústim 24 do ob jímky 2» kde sa po stuhnutí kovu vytvoří pevné a spoíahlivé spojenie koncov výstuže.A steel tube 2 is inserted into the casting hole of the sleeve 2, 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, locked by a fuse 6, slunged by a conical outlet channel to the prefabricated casting channel 3 and to the pre-mounted adjusting bracket 7 in a horizontal position. By means of a screw press 8, the two-piece casting channel 1 is pressed against the sleeve 2 to seal the casting system. A centering plate 9 is inserted into the opening 24 of the two-part casting channel 4, onto which the steel removable plate 10 is placed over the main inlet opening. The reaction crucible 22 is placed on a two-part casting channel 4 so as to cover the centering plate 9. The aluminothermal dose 12 poured into the reaction crucible 22 is ignited by an aluminothermic match and covered with a lid 22. orifice 24 into the receptacle 2 where a solid and reliable connection of the reinforcement ends is formed after the metal has solidified.

Súprava podía vynálezu zabezpečuje dobré zalievanie koncov výstuží v objímke, kde vznikne nerozoberateíné a pevné spojenie. Pevnost v tahu objímkového spoja sa vyrovná pevnosti nespojovanéj výstuže. Spojovat sa možu nezvariteíné betonářské ocele, lebo teplo zálievkovej ocele nepriaznivo neoyplyvňuje vlastnosti spojovaných materiálov.The kit according to the invention ensures good watering of the ends of the reinforcements in the sleeve, where an unbreakable and firm connection is formed. The tensile strength of the sleeve joint is equal to that of the unbonded reinforcement. Non-weldable reinforcing steels can be joined because the heat of the grout steel does not adversely affect the properties of the materials to be joined.
