Description
Vynález sa týká spojky najma na trubkové lešenie používané v stavebníctve, určenej na flxovanie vzájomnej polohy dvoch trubiek vo vzájomne kolméj polohe.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe scaffolding connector for use in the building industry for flipping two pipes relative to one another.
Doteraz sa na daný účel používajú spojky vytvořené vhodné ohnutým a profilovaným kovovým plechom s přítlačným mechanizmom vytvořeným jazýčkom ovládaným skrutkou vedenou v matici. Nevýhodou týchto spojok trubkových lešení je technologická náročnost ich výroby, vysoké spotřeba kovového materiálu, potřeba maziva a ošetrovania závitu, montáž vyžadujúce upevňovanle kTúčom a životnost ovplyvnená najma zoxidovanim skrutkového spoja. Montáž a demontáž za rftznych klimatických podmienok v rfiznych výškách a vzhTadom na potřebu manipulácie so skrutkovým spojom je nevýhodná.To date, couplings formed by a suitable bent and profiled metal sheet with a pressing mechanism formed by a screw-guided screw guided in a nut are used for this purpose. The disadvantages of these tubular scaffolding couplings are the technological demands of their manufacture, the high consumption of metal material, the need for lubricant and thread treatment, the assembly requiring fastening to the keys and the service life affected in particular by the oxidation of the screw connection. Assembly and disassembly under different climatic conditions at close heights and in view of the need to handle the screw connection is disadvantageous.
Podstatou spojky najma na trubkové lešenie podTa vynálezu je to, že pozostáva zo spony vytvorenej z ocelového prutu uzavretého v tvare písmena 0 a ohnutého do tvaru jeden a pol vlny, pričom poloměr ohnutia strednej vlny je menší ako poloměr prítlačnej trubky; z dvoch klinov lichoběžníkového tvaru ohnutých do tvaru písmena V a dvoch vymedzovacích ok vytvořených z ocelového prutu uzavretého v tvare písmena 0.The essence of the pipe scaffolding coupling according to the invention is that it consists of a clamp formed of a steel rod closed in the shape of the letter 0 and bent into a one-and-a-half wave shape, the radius of bending of the medium wave being smaller than the radius of the pressing tube; two trapezoidal wedges bent into a V - shape and two stitches formed from a steel bar closed in the shape of a letter.
Hlavné výhody spojky najma na trubkové lešenie spočívajú v zjednodušení technologické j náročnosti výroby, v znížení spotřeby kovového materiálu, v odstránení potřeby maziva, v zjednodušení montáže a demontáže pomocou kladiva a vo zvýšení životnosti.The main advantages of the pipe scaffolding coupler are, in particular, the simplification of the technological demands of production, the reduction of metal material consumption, the elimination of the need for lubricant, the simplification of assembly and disassembly with a hammer and the increased service life.
Spojka najma na trubkové lešenie podTa vynálezu je v príkladnom provedení znázorněná na pripojenom výkrese, kde na obr. 1 je nárys, na obr. 2 bokorys a na obr. 3 pfidorys.The pipe scaffolding connector according to the invention is shown in the accompanying drawing in an exemplary embodiment. 1 is a front view, FIG. 2, and FIG. 3 pfidorys.
Spojka najma na trubkové lešenie podTa vynálezu je tvořená sponou J. vytvořenou z oceThe pipe scaffolding connector according to the invention is formed by a clamp 10 made of steel
226 583 l’ového prutu uzavretého v tvare písmena O a ohnutého do tvaru jeden a pol vlny, pričom poloměr ohnutla strednej vlny je menSí ako poloměr prítlačnej trubky 4; dvorní klinmi 2 lichoběžníkového tvaru ohnutých do tvaru písmena V; dvorní vymedzovacími okami J vytvořenými z ocelového prutu uzavretého v tvare písmena 0. Činnost a funkcia spojky najma na trubkové leSenie, podl’a vynálezu, je následovná: Po navlečení spony J. na přítlačná trubku a nosnú trubku £ sa nasadia vymedzovacie oké cez krajné vlny spony _£ tak, aby sa spona J. opřela o přítlačná trubku £ a vymedzovacie oká Jo nosná trubku 2, do vzniklých otvorov sa kladivom zasuná kliny 2. Pri spojení trubiek % spojkou podl’a vynálezu vznikajá tri opěrné body so zvýšeným měrným tlakom po obvode prítlačnej trubky í zabezpečujáce zvýšenie stability spoja.226 583 of an O-shaped closed rod and bent into a one-and-a-half-wave form, the radius of bending of the medium wave being smaller than the radius of the pressure tube 4; trapezoidal shaped wedges 2 bent to a V-shape; The operation and function of the coupling, in particular for the scaffolding according to the invention, is as follows: After inserting the clamp J on the pressure tube and the support tube 8, the spacer meshes are fitted over the edge waves. The wedges 2 are inserted into the openings by a hammer 2. When connecting the pipes with the coupling according to the invention, three support points are created with an increased specific pressure after the clamping pipe. the circumference of the pressure tube 1 to increase the stability of the joint.
