Description
Vynález sa týká zariadenia na tepelné delenie železobetonu.BACKGROUND OF THE INVENTION The invention relates to a device for the thermal partitioning of reinforced concrete.
Pri deštrukcii železobetonových stavieb a pri zarážaní železobetonových stípov do terénu je často potřebné uskutočniť delenie železobetonu. Doteraz známe spůsoby spočívajú prevažne na mechanickom principe, při ktorom sa buď ručným sekáčkom, elektrickým príklepovým, alebo pneumatickým kladivem rozrušuji! betonové časti a ocelová výstuž sa dělí nástrojmi na obrábanie kovov. Tieto spůsoby sú nevýhodné, nakolko sú náročné na fyzickú silu, pri delení, připadne zarovnávaní materiálu vzniká vysoká prašnost, práca je velmi hlučná a prácnosť delenia je velká a produktivita práce nízká.In the destruction of reinforced concrete structures and when driving reinforced concrete beams into the ground, it is often necessary to carry out the separation of reinforced concrete. So far known methods are based mainly on the mechanical principle, whereby either a manual chopper, an electric hammer or a pneumatic hammer breaks! concrete parts and steel reinforcement are divided by metalworking tools. These methods are disadvantageous because they are demanding on physical strength, high dustiness is generated when dividing, eventually aligning the material, the work is very noisy and the labor of cutting is great and the labor productivity low.
Tieto nevýhody odstraňuje zariadenie na tepelné delenie železobetonu podlá vynálezu. Predmetom vynálezu je teda zariadenie, ktorého podstatou je, že pozostáva z posuvovej rúrky, napojenej na přívod kyslíka, na ktorej je posuvné uložený injektor s násypkou, ktorý je opatřený uzatváracou páčkou přívodu vzduchu a na ktorý je cez spojku napojená spalovacia rúrka, podopieraná vodiacou objímkou umiestnenou na posuvovej rúrke.These disadvantages are eliminated by the reinforced concrete thermal separation apparatus according to the invention. Accordingly, it is an object of the present invention to provide a device comprising a feed tube connected to an oxygen supply on which an injector with a hopper is provided, which is provided with a shut-off lever for an air supply and through which a combustion tube is supported by a coupling sleeve supported by a guide sleeve. located on the feed tube.
Hlavnou výhodou zariadenia podlá vynálezu je, že sa dosiahne vysoká produktivita práce pri nižšej hladině hluku, čím sa dosiahne úspora pracovných sil a zlepší sa hygiena práce. Navýše práca so zariadením podlá vynálezu je nenáročná na fyzickú silu obsluhy.The main advantage of the device according to the invention is that high productivity is achieved at a lower noise level, thus saving labor and improving work hygiene. Moreover, the work with the device according to the invention is undemanding on the physical strength of the operator.
Na priloženom výkrese je znázorněný v schematiekom náryse příklad uskutočnenia zariadenia podlá vynálezu.In the accompanying drawing, an exemplary embodiment of the device according to the invention is shown schematically.
Zariadenie podlá vynálezu, ako je znázorněné na výkrese, pozostáva z posuvovej rúrky 9, ktorá je napojená na přívod 10 kyslíka a na ktorej je posuvné uložený injektor 11 s násypkou 4. Injektor je opatřený uzatváracou páčkou 5 přívodu 6 vzduchu. K injektoru 11 je cez spojku 3 napojená spalovacia rúrka 2, podopieraná vodiacou objímkou 7 umiestnenou na posuvovej rúrke 9. Činnost zariadenia podlá vynálezu je nasledovná. Do násypky 4 sa nasype feromangán, ferosilícium alebo jemný křemičitý piesok. Volný koniec spalovacej rúrky 2 sa nahřeje na zápalnú teplotu a cez posuvovú rúrku 9 sa spustí přívod kyslíka 10, čím príde k horeniu rúrky a k vzniku velkého množstva tepla. Koncom spalovacej rúrky 2 sa priblíži zariadenie k železobetonu 1. Uzatváracou páčkou 5 sa otvorí přívod vzduchu 6, ktorým sa dopraví feromangán, ferosilícium alebo jemný křemičitý piesok z násypky 4 cez spojku 3 do spalovacej rúrky 2. Tým na jej konci vznikne velké množstvo tepla, ktorým sa v prúde kyslíka zabezpečí spalovanie železobetonu a vytvorenie reznej spáry vyfukováním splodín horenia z miesta řezu. Spalovacia rúrka 2 je do miesta horenia posúvaná cez vodiacu objímku 7 pohybom posuvovej skrutky 8.The device according to the invention, as shown in the drawing, consists of a feed pipe 9 which is connected to an oxygen inlet 10 and on which an injector 11 with a hopper 4 is slidably mounted. The injector is provided with a closing lever 5 of the air inlet 6. A combustion tube 2 is connected to the injector 11 via a coupling 3 supported by a guide sleeve 7 located on the feed tube 9. The operation of the device according to the invention is as follows. Ferromanganese, ferro-silicon or fine quartz sand is poured into the hopper 4. The free end of the combustion tube 2 is heated to the ignition temperature and the oxygen supply 10 is triggered through the feed tube 9, causing the tube to burn and to generate a large amount of heat. At the end of the combustion tube 2, a device for reinforced concrete 1 is approached. The closing lever 5 opens the air inlet 6, which transports the ferro-manganese, ferro-silicon or fine quartz sand from the hopper 4 through the coupling 3 into the combustion tube 2. This generates a large amount of heat at its end, by which the reinforced concrete is combusted in the oxygen stream and the cutting joint is formed by blowing the combustion products from the cutting point. The combustion tube 2 is moved to the burning location via a guide sleeve 7 by moving the feed screw 8.
Zariadenie na tepelné delenie železobetonu je možné využiť hlavně v stavebníctve pri vysokej produktivitě práce a nižšej hladině hluku.The equipment for the thermal separation of reinforced concrete can be used mainly in the construction industry with high labor productivity and lower noise level.
