Abstract

Odnímatelné zábradlie pozostáva z dvoch nosných stlpov medzi sebou přepojených madlom. Riešenýra problémov je zdokonalenie zábradlia, aby bolo použitelné ako stavebnica. To sa dosahuje tým, že v hornej časti nosných stlpov je prídržná konzolka s bočným zárezom pre madlo, opatřená gravitačným uzávěrom, a v dolnej časti nosných stlpov sú záchytné sedlá dolnej priečky, ktorá je spolu s madlom včleněná do samostatného rámu.The removable railing consists of two supporting posts interconnected by a handrail. The solution to the problem is to improve the railing so that it can be used as a kit. This is achieved by having a retaining bracket with a side notch for the handrail in the upper part of the supporting posts, equipped with a gravity lock, and in the lower part of the supporting posts there are retaining seats for the lower crossbar, which is integrated into a separate frame together with the handrail.

Vynález se týká odnímatelného zábradlia pozostávajúceho z dvoch nosných stlpov, medzisebou přepojených spojovacím Slenom, upevnitelného na hornú časť betonových, či ocelovýchkonštrukcií šácht.BACKGROUND OF THE INVENTION The present invention relates to a removable handrail consisting of two load-bearing pillars interconnected by an interlocking sleeve that can be attached to the top of a concrete or steel shaft structure.

Podlá známého stavu techniky bývá spojovací člen medzi nosnými stlpmi bud retaz, alebomadlo. V případe, že sú nosné stlpy medzi sebou spojené iba retazou, je zábrana pádu člověkado šachty nedokonalá. Známy je aj odnímatelný rám, ktorého nosné stlpy sú v hornéj častistočené do spoločného madla a ktoré sú v strednej časti přepojené prepojovacou žrdou. Takétoriešenie má nevýhodu najmS v tem, že otvory, do ktorých sa takéto zábradlie vsádza, musiabyť vytvořené v přesných rozst.upoch. Odnímatelné zábradlie může byť dalej vytvořené aj z le-šenářských rúrok, spojených příslušnými mechanickými spojkami. Nevýhodou takýchto lešení je,že bez dalšej konštrukčnej úpravy, ktoré požadujú normy, t. j. bez použitia okopového plechu,nie je možné ich pre tento účel uplatnit.According to the prior art, the connecting member between the supporting pillars is either a chain or a handle. In the case where the support posts are connected to each other by a chain only, the fall of the manado is imperfect. Also known is a removable frame, the bearing pillars of which are often coiled in the upper handrail and which are interconnected in the middle by a connecting rod. Such a solution has the disadvantage in particular that the openings into which such handrails are inserted must be formed in precise spans. Furthermore, the removable handrail may also be made of polishing tubes connected by respective mechanical couplings. The disadvantage of such scaffolds is that without further construction, which requires standards, i.e. without the use of sheet metal, they cannot be used for this purpose.

Uvedené nevýhody odstraňuje odnímatelné zábradlie podlá vynálezu, ktorého podstata spo-čívá v tom, že v hornej časti nosných stlpov je prídržná konzola s bočným zárezom pre madlo,opatřené gravitačným uzáverom, v dolněj časti nosných stlpov sú zachytené sedlá dolněj priečky,ktorá je spolu s madlom včleněná do samostatného rámu. Výhodou odnímatelného zábradlia podlá vynálezu je, Že má stavebnicový charakter, že jelahko montovatelné a demontovatelné a že jeho montážné otvory sí nevyžadujú přesný rozostup,táže můžu byť vzhledom na priemer nosných stlpov dimenzované s menšou vůlou. To má za následokaj zvýšenie stability zábradlia. Alternativně je výhodné, ked gravítačný uzávěr je vyhotovenýako zvislý kolík opatřený zvislou drážkou pre vodiaci čap upevněný v prídržnej konzolke nadjej bočným zárezom a zasunutý do vodiaoeho uška upevněného na prídržnej konzolke pod jej boč-ným zárezom. Tým sa vytvoří konštrukčne jednoduchý a funkčně spolehlivý gravitaěný uzávěr. Je tiež výho-dné, ked dolná časti nosného stlpa je opatřená aspoň jedným radiálnym výstupkom a je zasunutádo otvoru pStice, pričom otvor pStice je opatřený aspoň jedným radiálnym výrezom pre radiálnyvýstupok. Tým sa jednoduchými prostredkami dosáhne blokovanie nosných stlpov zábradlia protiuvolneniu v podmienkách, ked je zábradlie kotvené v kotvových pSticiach. Příklad vyhotovenia odnímatelného zábradlia je znázorněný na výkresoch, na ktorýchobr. 1 představuje axonometrický pohlad na jeden blok zábradlia, obr. 2 detail A z obr. 1,obr. 3 detail pStice zábradlia v inej alternativě, obr.í pSdorysné rozmestnenie pStic priobdlžnikovom usporiadaní jednotlivých blokov zábradlia, obr.5 půdorysnej rozmiestnenie pStícpri šesíúholníkovom usporiadaní jednotlivých blokov zábradlia a obr.6 půdorysné rozmiestneniepStíc pri štvorcovom usporiadaní blokov zábradlia na betónovej, či ocelověj konštrukcií hornejčasti šachty.The above-mentioned disadvantages are eliminated by the removable handrail according to the invention, which consists of a retaining bracket with a lateral notch for the handrail provided with a gravity closure in the upper part of the support pillars; handrail incorporated into a separate frame. The advantage of the removable handrail according to the invention is that it is of modular nature, that it is easy to assemble and dismantle and that its mounting holes do not require a precise spacing; This results in increased railing stability. Alternatively, it is preferred that the gravity closure is in the form of a vertical pin provided with a vertical guide pin groove fixed in the retaining bracket above the lateral notch and inserted into the water tab attached to the retaining bracket below its lateral notch. This creates a structurally simple and functionally reliable gravity seal. It is also advantageous when the lower portion of the support pillar is provided with at least one radial projection and is inserted into the opening of the housing, wherein the opening is provided with at least one radial recess for the radial projection. In this way, by means of simple means, it is possible to block the rails of the railing against loosening in conditions when the railing is anchored in the pStic anchors. An example of an embodiment of a removable railing is shown in the drawings in which FIG. Fig. 1 is a perspective view of one railing block, Fig. 2 detail A of Fig. 1; Fig. 3 is a plan view of the railing arrangement of the individual railing blocks, Fig. .

Odnímatelné zábradlie pozůstává z dvoch stlpov A,na ktorých hornú časť je privarená prí-držná konzolka 2 s bočným zárezom 3 pre madlo 4. Prídržná konzolka 2 je totiž opatřená gravi-tacným uzáverom 2- v dolnej časti nosných stlpov 1_ sú privarené záchyné sedla 6, v ktorých jeuložená dolná priečka 7. Táto spolu s madlom vytvára samostatný rám 8., ktorý je dalej tvoře-ný střednou priečkou 3_ a pletivom, sietovinou, perforovaným plechom, či iným vhodným materi-álom. Gravítačný uzávěr 5 je vytvořený ako zvislý plochý kolík opatřený zvislou drážkou 10 prevodiaci čap 11 upevněný v prídržnej konzolke 2 nad jej bočným zárezom 2· Gravítačný uzávěr5 je zasu.utý do vodiaceho uška 12 privareného na prídržnej konzolke 2 pod jej bočným zárezom 3. Dolná časť nosného stlpa 2 je vyhotovená bud ako pokračovanie rúrkového materiálu tohotonosného stlpa 2> a je určená pre zasunutia do otvorov 13 v betone 14 (obr. 1), alebo je opatře-ná dvomi radiálnymi výstupkami 15 (obr. 3) a je zasunutá do otvoru 1_6 pStice 17. Otvor 16 pSti-ce 11 je opatřený dvomi radiálnymi výrezmi 12« oez ktoré sa přesunů oba radiálně výstupky25. Vzhladom na poměrně malú výšku pStice 17 a z toho vyplývajúcu určitú labilnost nosnýchstlpov 2 zábradlia, můžu byť v tomto případe jednotlivé bloky zábradlia navzájom pospájanéretiazkou 22·The removable handrail consists of two pillars A, on which the retaining bracket 2 is welded to the upper part with a lateral notch 3 for the handle 4. In fact, the retaining bracket 2 is provided with a gripping seat 2 in the lower part of the supporting pillars 7. in which a lower crossbar 7 is inserted. This together with the handrail forms a separate frame 8, which is further formed by a middle bar 3 and a netting, a netting, a perforated sheet or other suitable material. The gravity closure 5 is formed as a vertical flat pin provided with a vertical groove 10, a gear pin 11 fixed in the retaining bracket 2 above its lateral notch 2. The gravity closure 5 is inserted into the guide ear 12 welded to the retaining bracket 2 below its lateral notch 3. Bottom the support pillar 2 is provided either as a continuation of the tubular material of this supporting pillar 2 and is intended to be inserted into the openings 13 in the concrete 14 (FIG. 1) or is provided with two radial projections 15 (FIG. 3) and is inserted into the opening The aperture 16 of the aperture 11 is provided with two radial cutouts 12 'which are moved by both radial projections 25. Due to the relatively small height of the rail 17 and the consequent certain lability of the rails 2, in this case, the individual railing blocks may be interconnected by a line 22 ·

Claims

3 264825, but at the same time that it is sufficiently resistant to anticipated horizontal or downwardly directed forces and also against deliberate release by the guardian. The rails 1 can also be mounted in the mounting holes, even when these inaccurate spacings are used because the pillars 7 are mounted individually. In this case, the inner diameters of the mounting openings may be more tight with respect to the outer diameters of the supporting pillars, thereby increasing the stability of the railing and preventing unwanted dismantling of the railing block as a whole as the block may be in case when the pillars Jt are terminated in the form of one-stroke (fig. 1), select only when k3 in both load-bearing pillars 1 is to produce a time-like lifting force in exactly the axial direction. Otherwise, the support piles 7 will crease. In the deliberate but unprofessional attempt to dismantle the entire railing block, the supporting pillars _! provided that the rail frame plane j) does not coincide with the plane in which the support rails are located, the lifting force being exerted eccentrically on the handle 4, i.e. in any case outside the planes 11. Also, the release of the railing frame 8 from the supporting pillars 1 is cured at random, in that both gravity closures need to be released at the same time. In the construction of the railing, it has been taken into account that the main force acting under normal operating conditions is transferred to the dangerous prism by the frictional support frames 1 in the opposite direction. transmitted from the frame i! nanoparticles 1 ' In an alternative where the load-bearing pillars 1, anchored to the metal plates 17, fixedly attached to the metal floor, as required in some of the operating areas of the nuclear power plants (FIG. 3), the support pillars 1 ' so that they are inserted into the openings of these faces 17 and then rotated about their vertical axis by 90 °. Only then the frame is mounted. Once the frame 8 has been mounted, it is no longer possible to select the whole block, since the rotation of the support frames 1, which have a relatively large bore in the bases 17, blocks the frame 8. After dismantling the railing, not the metal base is an obstacle for walking through the operating area, as the low and bevelled upper peripheral edges. SUBJECT OF THE INVENTION
