Zapiralo jaškaShaft closure
Izum zadeva zapiralo jaška za jaškovno zgradbo, potekajočo v bistvu v navpični smeri, z zgornjim jaškovnim elementom, ki ga predvsem tvori jaškovni vrat in ki s svojo notranjo steno omejuje jaškovni odsek ter na katerem se posredno preko vsaj enega izravnalnega elementa opira okvir pokrova, ki sprejme pokrov.The invention relates to a shaft closure for a shaft structure, extending substantially in the vertical direction, with an upper shaft element, mainly formed by a shaft door, which with its inner wall restricts the shaft section and on which the frame of the lid indirectly rests on at least one of the counterbalancing elements. accept cover.
Tovrstne znane jaškovne zgradbe služijo temu, da v zemljo položene kanale, naprimer kanale za umazano vodo, kanale za deževnico, kanale za hišni in zemljiščih odtok, kanale za mešano vodo pa tudi kabelske kanale za položitev jakotočnih in šibkotočnih kablov, telefonskih kablov, televizijskih kablov ipd. naredimo dostopne z zemeljske površine, da v teh kanalih izvajamo dela, jih torej naprimer odmašujemo, pregledujemo stene kanalov, polagamo dodatne kable ipd.Such well-known shaft structures are used for laying channels in the ground, such as dirty water channels, rainwater channels, domestic and land drainage channels, mixed water channels, as well as cable channels for the placement of high and low-current cables, telephone cables, television cables. etc. make accessible from the ground, to perform work in these channels, for example, clearing them, inspecting the walls of channels, laying additional cables, etc.
Tovrstne jaškovne zgradbe običajno naredijo iz posameznih jaškovnih elementov iz betona in/ali umetne snovi, ki so zatesnjeni preko ustreznih tesnil. Zadnji zgornji jaškovni element nosi okvir pokrova, ki sprejme pokrov, po katerega snetju je jaškovna zgradba dostopna. Zlasti če se pokrov nahaja na javni površini, kot je cesta, trg ali pešpot, je treba zgornjo stran pokrova in okvira pokrova natančno prirediti višini zemljišča, pri čemer je treba računati na to, da se ta višina zemljišča lahko menja, naprimer tedaj, ko vgradijo novo cestno oblogo. Nadalje se dogaja, da višina terena neposredno ob pokrovu pogosto ni vodoravna, marveč nagnjeno poteka, saj so ne nazadnje naprimer ceste bombirano izvedene in so pešpoti v smeri proti robu pločnika nagnjene, da je zagotovljen odtok vode. V takem primeru morata biti položaja pokrova in okvira pokrova dodatno prilagojena nagibu okolišne višine.Usually, such shaft structures are made of individual shaft elements made of concrete and / or plastic, which are sealed via suitable seals. The rear upper shaft element bears the lid frame which accepts the lid, after which the shaft structure is accessible. In particular, if the cover is located in a public area, such as a road, market or footpath, the top of the cover and the frame of the cover must be precisely adjusted to the height of the land, taking into account that this height of the land may change, such as when they are installing a new road lining. It is further the case that the height of the terrain immediately adjacent to the cover is often not horizontal, but rather inclined, since, for the last time, the roads are bombed and the footpaths inclined towards the edge of the pavement to ensure water drainage. In such a case, the position of the lid and the frame of the lid must be further adapted to the slope of the surrounding height.
Da je to možno, predvidijo med zgornjo čelno ploskvijo zgornjega jaškovnega ele2 menta in spodnjo stranjo okvira pokrova vsaj en izravnalni element. Ta izravnalni element je lahko narejen iz na kraju samem pripravljenega in vgrajenega betona. Pomanjkljivost je, da ima tak beton zaradi slabe in nestrokovne predelave majhno kakovost v primerjavi z zgornjim jaškovnim elementom, tako da struktura betona ni homogena in ima tak izravnalni element majhno trdnost in kratko življenjsko dobo. Zlasti pri močno uporabljanih cestah prihaja zaradi sil, delujočih na pokrov in okvir pokrova, vedno znova do neželenih vgreznitev pokrova.For this to be possible, at least one offset element is provided between the upper face of the upper shaft member and the underside of the lid frame. This leveling element may be made of on-site prepared and embedded concrete. The disadvantage is that due to poor and unprofessional processing, such concrete has a low quality compared to the upper shaft element, so that the concrete structure is not homogeneous and has such a leveling element of low strength and short life. Especially on heavily used roads, the forces acting on the hood and the hood frame result in unwanted hindrances of the hood.
Da se tem pomanjkljivostim izognemo, je že znano, da kot izravnalni element uporabimo enega ali več vnaprej pripravljenih distančnih obročev. Ti vnaprej pripravljeni distančni obroči sicer izpolnjujejo zahteve glede kakovosti betona in trdnosti, toda za povezavo teh distančnih obročev so, četudi so le-ti s čelne strani za medsebojno fiksiranje položaja ozobljeni, še vedno potrebni maltni stiki, katerih izvedba in kakovost sta odvisni od vsakokratnega delovnega osebja in sta zato nedoločljivi. Zgornjo stran pokrova zaradi prilagoditve k višini okolišne ploskve lahko tudi pri uporabi vnaprej pripravljenih distančnih obročev nagnemo le z betonskimi stiki različnih višin.In order to avoid these drawbacks, it is already known to use one or more pre-assembled spacer rings as a leveling element. These prefabricated spacer rings, although they meet the requirements for concrete quality and strength, but to connect these spacer rings, even if they are toothed from the front, they still require mortar joints whose construction and quality depend on each and therefore are undetectable. To adjust the height of the surrounding surface, the top of the lid can only be tilted with pre-prepared spacers of different heights when using pre-prepared spacer rings.
Bistven problem, ki nastopa pri znanih konstrukcijah, je tesnost. Tako je nezaželeno, če denimo pri obilnih padavinah večje količine vode preko jaškovne zgradbe stečejo v kanal. Če gre naprimer za kanal za umazane vode, tedaj take zajetne količine vode, ki se pojavljajo samo začasno, povzročijo, da čistilne naprave odpovedo. Pogosto tudi presek kanalov ni tako dimenzioniran, da zmore sprejeti nenadoma prihajajoče večje količine vode. Pri kabelskih kanalih lahko vdirajoče količine vode povzročijo kratke stike. Zato gradbene oblasti zahtevajo, da imajo jaškovne zgradbe od vznožja jaška do spodnjega roba pokrova tesnost do 50 kPa. Pri izravnalnem elementu, narejenem iz betona na kraju samem, tolikšna tesnost ni zagotovljena, saj zaradi majhne kakovosti betona in nehomogene strukture betona voda lahko prestopa skozi tak beton. Pri uporabi vnaprej pripravljenih distančnih obročev je možen dostop vode v območju maltnih stikov.An essential problem encountered in known structures is tightness. Thus, it is undesirable if, for example, in heavy rainfall, large quantities of water flow through the shaft structure into the channel. For example, if it is a dirty water channel, then such large quantities of water, which appear only temporarily, will cause the treatment plants to fail. Often, the cross-section of the canals is not so large that it is able to receive suddenly large quantities of water. For cable ducts, leaking amounts of water can cause short circuits. Therefore, the construction authorities require shaft shafts to have a tightness of up to 50 kPa from the base of the shaft to the bottom edge of the hood. In the case of a leveling element made of concrete on site, such tightness is not guaranteed, because of the low quality of the concrete and the inhomogeneous structure of the concrete, water can pass through such concrete. When using pre-prepared spacer rings, water can be accessed in the area of mortar joints.
Nadalje naj ima jaškovno zapiralo primerno dolgo obratovalno dobo in ne sme prihajati do nikakršnih poškodb zaradi mraza, prometne obtežbe, nezadovoljive kakovosti betona ipd. Slednjič je potrebna ustrezna zanesljivost proti premiku zapirala jaška glede na preostalo jaškovno zgradbo. Vse te zahteve se dajo pri znanih konstrukcijah komajda izpolniti.Furthermore, the shaft closure should have a suitable long service life and must not be damaged by cold, traffic loads, poor quality of concrete, etc. Lastly, adequate reliability is required against the movement of the shaft closure relative to the rest of the shaft structure. All of these requirements can hardly be met with known structures.
Pri odtokih v podu, naprimer v sanitarnih prostorih, v ravnih strehah, terasah ipd., je že znano, da v pod zalijemo z odtočno cevjo preko sifonskega zapirala povezan lonec, v katerega zgornji odprtini je zatesnjeno in premakljivo nameščen cevni nastavek, ki na svojem zgornjem koncu nosi rešetko. Voda teče preko rešetke in cevnega nastavka v lonec in od ondod naprej odteka preko odtočne cevi. S tem, ko je cevni nastavek premakljiv, lahko raven rešetke prilagodimo preostali višini tal, kar je potrebno naprimer pri poplavljenju tal. Za popolno zatesnitev med cevnim nastavkom in zgornjo odprtino lonca pri taki znani izvedbi ne gre in tudi ni potrebna, saj v prehodnem območju med loncem in cevnim nastavkom tako in tako ni dostopa vode, temveč voda preko rešetke direktno teče v cevni nastavek. Predvsem pa pri tej znani izvedbi ni možna nikakršna prilagoditev na nagnjeno površino tal.For floor drains, for example in sanitary rooms, in flat roofs, terraces, etc., it is already known that a pot is connected to the floor by means of a siphon closure, with a siphon closure connected to it; the upper end wears a grille. Water flows through the grate and pipe fitting into the pot and from there flows out through the drain pipe. By moving the pipe nozzle, the level of the grid can be adjusted to the remaining floor height, which is necessary for example when flooding the floor. In such a known embodiment, complete sealing between the pipe nozzle and the upper orifice of the pot is not necessary and is not necessary, since there is no water access in the transition zone between the pot and the pipe nozzle, but water flows directly into the pipe nozzle through the grate. Above all, in this known embodiment, no adjustment to the sloping surface of the soil is possible.
Pričujoči izum si je zastavil nalogo, izogniti se omenjenim pomanjkljivostim in ustvariti zapiralo jaška, ki ustreza postavljenim zahtevam glede tesnosti, a ga je kljub temu možno natančno prilagoditi k višini sosedne površine, četudi je ta nagnjena, in je tudi varovano proti neželenemu premiku.The present invention has set itself the task of avoiding the aforementioned disadvantages and of creating a shaft closure that meets the set requirements for tightness, but can nevertheless be precisely adjusted to the height of the adjacent surface, even if it is inclined, and is also protected against unwanted movement.
Za rešitev te naloge izum, izhajajoč iz zapirala jaška uvodoma opisane vrste, predlaga, da je predviden z okvirom pokrova povezljiv, dol štrleč in čez noter štrlečo štrlino notranje stene zgornjega jaškovnega elementa z odmikom segajoč cevni nastavek in da je razporejeno ta razmik zapolnjujoče elastično tesnilo. S tem, da tesnilo nalega na noter štrlečo štrlino in premošča odmik med to štrlino in zunanjo stranjo cevnega nastavka, je omogočeno, da lego okvira pokrova prilagodimo k višini sosedne površine, četudi je le-ta nagnjena, torej ko os cevnega nastavka ne poteka vzporedno z osjo zgornjega jaškovnega elementa, temveč s to osjo oklepa kot, a je vendarle zagotovljena absolutna tesnost. Seveda morajo biti dimenzije in presek cevnega nastavka prilagojeni na štrlino mejočemu notranjemu preseku zgornjega jaškovnega elementa. Praviloma je ta notranji presek krožen in ima cevni nastavek ustrezno obliko. V poštev pa pride tudi druga oblika preseka.In order to accomplish this task, the invention, based on the closure of the shaft of the type described above, proposes that a hinged, downward projecting and inwardly projecting projection of the inner wall of the upper shaft element with a displacement extending a tubular attachment be provided with the lid frame and that this gap is filled with a filling elastic seal . By ensuring that the gasket fits in the projecting projection and bridges the distance between this projection and the outer side of the tube attachment, it is possible to adjust the position of the cover frame to the height of the adjacent surface, even if it is inclined, ie when the axis of the tube attachment does not extend parallel with the axis of the upper shaft element but with this axis it encloses an angle, but absolute tightness is nevertheless ensured. Of course, the dimensions and cross-section of the pipe fitting must be adapted to the projection of the adjacent inner cross-section of the upper shaft element. As a rule, this inner cross-section is circular and has a tubular nozzle in the proper shape. Another cross-sectional design may also be considered.
Tudi izbira gradiva, iz katerega je narejen cevni nastavek, ni kritična. Pomembna je ustrezna vodotesna zasnova cevnega nastavka. Ta bi utegnila biti primerna tudi pri uporabi ustreznega vodotesnega betona za izdelavo cevnega nastavka. Če je okvir pokrova betonski, bi prišlo v poštev tudi, da sta cevni nastavek in okvir pokrova izvedena v enem kosu. Smotrno pa je, če je cevni nastavek iz takega gradiva, ki v majhnih mejah dopušča tudi določeno deformacijo, da se lahko izravnajo odstopanja, torej naprimer iz umetne snovi, zlasti iz s steklenimi vlakni ojačane umetne snovi, iz kovine, predvsem iz pločevine, v danem primeru tudi iz trde gume ali podobnih gradiv.Also, the choice of material from which the hose fitting is made is not critical. Adequate watertight design of the pipe fitting is important. This may also be suitable for the use of suitable waterproof concrete for the construction of a pipe fitting. If the lid frame is concrete, it would also be advisable to have the tubular nozzle and lid frame made in one piece. However, it is advantageous if the tubular nozzle is of such material, which also allows a small deformation in a small range, to compensate for deviations, for example from plastic, in particular fiberglass reinforced plastic, from metal, in particular sheet metal, in if applicable, hard rubber or similar materials.
Cevni nastavek z okvirom pokrova lahko potrebno povežemo na gradbišču, lahko pa tudi vnaprej v izdelovalnem obratu. Zveza je lahko vijačna, pa tudi zlepna ali zvama. Predvsem ko sta okvir pokrova ali vsaj del le-tega in cevni nastavek kovinska ali ko sta vgradni del okvira pokrova in cevni nastavek iz umetne snovi, je zvaritev teh delov drugega z drugim smotrna, saj s tem naredimo vodotesno zvezo.The hose fitting with the cover frame can be connected at the construction site as necessary, but also in advance at the manufacturing plant. The relationship can be screwed, but also screwed or twisted. Particularly when the cover frame or at least part of it and the pipe fitting are metal, or when the fitting part of the cover frame and the pipe fitting is made of plastic, welding these parts to each other is sensible, since this makes a waterproof connection.
Prednostna izvedbena oblika nastane, če je štrlina razporejena na zgornjem koncu zgornjega jaškovnega elementa, tesnilo pa ima prečno na vzdolžno os cevnega nastavka potekajoč svoj nastavek, ki nalega na zgornjo čelno stran zgornjega jaškovnega elementa. S tem je preprečeno premikanje tesnila v vzdolžni smeri cevnega nastavka pri nameščanju cevnega nastavka v zgornji jaškovni element.A preferred embodiment is formed when the projection is disposed at the upper end of the upper shaft element, and the gasket has a transverse projection extending to the longitudinal axis of the tube attachment which rests on the upper front face of the upper shaft element. This prevents the gasket from moving in the longitudinal direction of the pipe fitting while installing the pipe fitting into the upper shaft element.
Kot tesnilo lahko uporabimo običajno tesnilo v obliki drsnega obroča ali običajno tesnilo v obliki kotalnega obroča, tesnilo pa lahko ima tudi stranska, na notranjo steno zgornjega jaškovnega elementa in/ali zunanjo steno cevnega nastavka nalegajoča rebra, tako da se tesnilni učinek še okrepi.As a seal, a conventional sliding ring seal or a conventional roller ring seal may be used, and the seal may also have lateral ribs on the inner wall of the upper shaft element and / or the outer wall of the tube attachment so that the sealing effect is further strengthened.
Ker je tesnilna zasnova zapirala jaška zagotovljena z od okvira pokrova dol štrlečim cevnim nastavkom v povezavi s tesnilom in je s tem cevnim nastavkom zapiralo tudi varovano proti premikom, zasnova in ureditev izravnalnega elementa nista več pomembni. Zato je ta izravnalni element lahko iz na kraju samem pripravljenega betona, pri čemer kakovost betona glede tesnilnega učinka ni več kritična. Bolje pa je, če izravnalni element sestoji iz enega ali več vnaprej pripravljenih delov. V tem primeru je koristno, če ima vnaprej pripravljeni izravnalni element izrez za sprejem prečno na vzdolžno os cevnega nastavka potekajočega nastavka tesnila. S tem se prepreči škodljiva obremenitev nastavka.Since the sealing design of the shaft closure is provided by a downwardly projecting tubular connection in connection with the gasket, and thus the tube adapter also secures displacement, the design and arrangement of the balancing element are no longer relevant. Therefore, this leveling element can be made of on-site concrete, and the quality of the concrete is no longer critical to the sealing effect. However, it is preferable that the balancing element consists of one or more pre-made parts. In this case, it is advantageous if the pre-assembled leveling element has a cutout for receiving transversely to the longitudinal axis of the tube connection of the running gasket adapter. This prevents harmful load on the attachment.
Vnaprej pripravljeni izravnalni element ima nadalje lahko v bistvu v smeri vzdolžne osi cevnega nastavka potekajoče reže, ki služijo za vnos malte za izravnavo višine, tako da je moč s tem izravnati določene višinske odstopke in tudi doseči nagnjenost pokrova.The pre-assembled leveling element may further have substantially slit-shaped slots in the direction of the longitudinal axis of the tube attachment for the purpose of introducing height-adjusting mortar, so that it is possible to compensate for certain height variations and also to achieve the inclination of the cover.
Nadalje je koristno, če je cevni nastavek koničen, ker s tem ta cevni nastavek laže vložimo v zgornji jaškovni element in je v večjem obsegu možno poševno postavljanje osi cevnega nastavka glede na zgornji jaškovni element za potrebe prilagajanja višine. Razen tega ta izvedbena oblika omogoča uvedbo cevnega nastavka v že razpoložljiv, v zemeljskih tleh premaknjen cevni nastavek, kar je potrebno tedaj, ko je treba zaradi nameščanja nove, zelo debele plasti cestne obloge na že razpoložljivo nivo ceste močno dvigniti in je zato tudi treba ustrezno prilagoditi površino pokrova.Further, it is advantageous if the nozzle is tapered, since this makes it easier to insert the nozzle into the upper shaft element and to a larger extent the oblique position of the axis of the pipe nozzle relative to the upper shaft element is possible for height adjustment purposes. In addition, this embodiment enables the insertion of the pipe nozzle into an already available soil-displaced nozzle, which is necessary when, due to the installation of a new, very thick layer of road surface, it is necessary to raise it to an already available level of the road and, therefore, adjust the cover surface.
V skicah je izum shematično predstavljen na osnovi izvedbenih primerov. Pri tem kaže sl. 1 izvedbeno obliko zapirala jaška po izumu v vzdolžnem prerezu, sl. 2a do 2c tri različne možnosti povezave cevnega nastavka z okvirom pokrova, sl. 3 montažo zapirala jaška po izumu, sl. 4 nadaljnjo izvedbeno obliko zapirala jaška po izumu v vzdolžnem prerezu, sl. 5 prerez po črti V-V s sl. 4, sl. 6 in 7 pa različni možnosti uporabe zapirala jaška po izumu pri povišanju nivoja ceste.In the drawings, the invention is schematically presented on the basis of embodiments. In this respect, FIG. 1 shows an embodiment of a shaft closure according to the invention in longitudinal section; 2a through 2c three different options for connecting the hose fitting to the cover frame, FIG. 3 shows the assembly of the shaft closure according to the invention; 4 shows a further embodiment of the shaft closure according to the invention in longitudinal section; FIG. 5 is a cross-sectional view taken along line V-V of FIG. 4, FIG. 6 and 7, different possibilities of using the shaft closure according to the invention in raising the level of the road.
Kot vidimo s sl. 1, ima zapiralo po izumu okvir i pokrova, ki je pri izvedbenem primeru po sl. 1 betonski in v katerem je predviden kovinski vložni del 2, na katerega nalega tu nepredstavljen pokrov. Okvir 1 pa je lahko tudi v celoti kovinski, kar je slučaj pri izvedbenem primeru po sl. 3, 4 in 6. Z okvirom 1 pokrova oz. s kovinskim vložnim delom 2 le-tega je povezan dol štrleč koničen cevni nastavek 3, ki s svojo zunanjo steno 4 z odmikom sega preko navznoter štrleče štrline 5 notranje stene kot vrat jaška zasnovanega zgornjega jaškovnega elementa 6 jaškovne zgradbe. Omenjeni odmik je zapolnjen z elastičnim tesnilom 7, ki potemtakem na eni strani nalega na štrlino 5, na drugi na zunanjo steno cevnega nastavka 3. Pri izvedbenem primeru po sl. 1 je to tesnilo v območju, nalegajočem na zunanjo steno 4 cevnega nastavka 3, opremljeno z rebri, ima pa lahko tudi drugačno obliko. Kot kaže skica, je štrlina 5 razporejena na zgornjem koncu zgornjega jaškovnega elementa 6, tesnilo 5 pa ima prečno na vzdolžno os cevnega nastavka 3 potekajoč nastavek 8, ki nalega na zgornjo čelno stran 9 zgornjega jaškovnega elementa 6, tako da je tesnilo 7 varovano proti zdrsu v smeri vzdolžne osi cevnega nastavka 3. Kot izravnalni element 10 služi pri iz6 vedbeni obliki po sl. 1 vgrajen na kraju samem pripravljen beton. Potrebno tesnost dosežemo s pomočjo tesno z okvirom 2 pokrova povezanega cevnega nastavka 3 in med zunanjo steno cevnega nastavka 3 in štrlino 5 zgornjega jaškovnega elementa 6 delujočega tesnila 7, pri čemer je s tako posebno ureditvijo tesnila omogočena tudi poševna postavitev vzdolžne osi cevnega nastavka 3 glede na vzdolžno os zgornjega jaškovnega elementa 6 za potrebe prilagoditve k strmemu nivoju sosedne površine.As can be seen from FIG. 1, the closure according to the invention has a frame i of the lid, which in the embodiment of FIG. 1 is concrete and in which is provided a metal insert 2, which is not provided with a cover not shown here. The frame 1 may also be entirely metal, which is the case in the embodiment of FIG. 3, 4 and 6. With frame 1 of the lid or. a metal conical part 2 thereof is connected by a downwardly projecting conical nozzle 3 which extends with its outer wall 4 through the projection of the upper shaft element 6 of the shaft structure through the inwardly projecting projection 5 of the inner wall. Said offset is filled with an elastic seal 7, which then rests on one side on the projection 5, on the other on the outer wall of the pipe fitting 3. In the embodiment of FIG. 1, this seal is provided with ribs in the area adjacent to the outer wall 4 of the pipe nozzle 3, but may also have a different shape. As shown in the drawing, the projection 5 is disposed at the upper end of the upper shaft element 6, and the seal 5 has a projecting nozzle 8 extending transversely to the longitudinal axis of the pipe shaft 8, which rests on the upper front face 9 of the upper shaft element 6, so that the seal 7 is secured against sliding in the direction of the longitudinal axis of the pipe fitting 3. The counterbalancing element 10 is used in the embodiment according to FIG. 1 built-in concrete prepared on site. The required tightness is achieved by means of a tightly fitting frame 2 of the connected tube connection 3 and between the outer wall of the tube connection 3 and the protrusion 5 of the upper shaft element 6 of the working gasket 7, whereby such special arrangement of the gasket also allows the oblique positioning of the longitudinal axis of the tube adapter 3 with respect to to the longitudinal axis of the upper shaft element 6 for the purpose of adapting to the steep level of the adjacent surface.
Cevni nastavek 3 je lahko narejen iz različnih gradiv, ki zagotavljajo tesnost proti tekočinam, prednostno iz kovine ali umetne snovi. V predloženem primeru, ko je vložni del 2 okvira 1 pokrova kovinski, je smotrno izdelati cevni nastavek 3 iz pločevine in ga z vložnim delom 2 povezati z varjenjem. Če pa je okvir pokrova v celoti betonski, je lahko tudi cevni nastavek 3 iz betona in ga formamo kar hkrati pri izdelavi okvira pokrova.Pipe nozzle 3 can be made of a variety of materials that provide tightness against liquids, preferably metal or plastic. In the present case, when the insert part 2 of the frame 1 of the cover is metal, it is advisable to make a tubing 3 made of sheet metal and connect it to the insert part 2 by welding. However, if the cover frame is entirely concrete, the pipe attachment 3 may also be made of concrete and can be molded at the same time as the cover frame is made.
Možno je, da cevni nastavek 3 šele na gradbišču povežemo z okvirom 1 pokrova ah ga na gradbišče dostavimo že kot vnaprej pripravljeno enoto.It is possible to connect the pipe nozzle 3 only at the construction site to the frame 1 of the cover ah and deliver it to the construction site as a pre-prepared unit.
Skice sl. 2a do 2c kažejo različne možnosti povezave cevnega nastavka 3 z okvirom 1 pokrova. Po sl. 2a zveza temelji na prirobnici 11 cevnega nastavka 3, ki je s pomočjo vijaka 12 in posredno preko gumijastega tesnila 13 povezan z okvirom pokrova.Figs. 2a through 2c show the various options for connecting tube 3 to the lid frame 1. According to FIG. 2a, the connection is based on the flange 11 of the pipe nozzle 3, which is connected to the lid frame by means of a screw 12 and indirectly via a rubber seal 13.
Pri izvedbeni obliki po sl. 2b je prirobnica 11 cevnega nastavka 3 s pomočjo posebnega lepila (lepilo za epoksi smolo ali lepilo za kovine) 14 povezana z okvirom 1 pokrova.In the embodiment of FIG. 2b, the flange 11 of the tube attachment 3 is bonded to the cover frame 1 by means of a special adhesive (epoxy resin or metal glue) 14.
Pri izvedbeni obliki po sl. 2c je prirobnica cevnega nastavka 3 z okvirom 1 pokrova oz. vložnim delom tega okvira 1 pokrova zvarjena pri 15. Možna je tako kovinska zvaritev kot tudi zvaritev umetnih snovi.In the embodiment of FIG. 2c is a flange of a pipe fitting 3 with a frame 1 of the lid or. the insertion portion of this frame 1 of the lid is welded at 15. Both metal welding and plastic welding are possible.
Sl. 3 kaže delovni pristop pri vgrajevanju zapirala jaška po izumu.FIG. 3 shows a working approach for the installation of a shaft closure according to the invention.
Po premaknitvi jaškovne zgradbe vključno zgornji jaškovni element 6 na zgornjo čelno stran 9 le-tega namestimo tesnilo 7 z njegovim nastavkom 8, tako da tesnilo nalega na štrlino 5 zgornjega jaškovnega elementa 6. Cevni nastavek 3 povežemo z okvirom 1 pokrova na primeren, zgoraj opisani način. Zatem na cevni nastavek 3 nanesemo drsno sredstvo in nato s pomočjo primerne priprave 16 okvir 1 pokrova s cevnim nastavkom 3 spustimo, ga na pravi višini in legi naravnamo in pritrdimo.After moving the shaft structure including the upper shaft element 6 to the upper front face 9, the gasket 7 is fitted with its attachment 8 so that the gasket fits into the protrusion 5 of the upper shaft element 6. Connect the hose nozzle 3 to the cover frame 1 as described above way. Then, a sliding means is applied to the pipe nozzle 3 and then, by means of a suitable device, 16 the frame 1 of the lid with the pipe nozzle 3 is lowered, adjusted and fixed at the correct height and position.
Zatem namestimo zunanji opaž 17 in prostor 18 med tem zunanjim opažem 17 in zunanjo steno 4 cevnega nastavka 3 zapolnimo z betonom, ki tvori izravnalni element 10. S cevnim nastavkom 3 se v zvezi s tesnilom 7 doseže potrebna tesnost kot tudi zagotovi potrebno fiksiranje proti premikanju. Ureditev štrline 5 kot tudi uporaba elastičnega tesnila 7 pa tudi konična zasnova cevnega nastavka 3 omogočajo poševno postavitev okvira 1 pokrova glede na zgornji jaškovni element 6 in s tem prilagoditev na razpoložljivi nagib površine, ki meji na okvir 1 pokrova.Subsequently, the outer formwork 17 and the space 18 between this outer formwork 17 and the outer wall 4 of the pipe nozzle 3 are filled with concrete forming a counterbalancing element 10. With the pipe nozzle 3, the necessary tightness is achieved with respect to the seal 7, as well as to provide the necessary anti-displacement fixation. . The arrangement of the projection 5, as well as the use of the elastic seal 7, as well as the conical design of the tube attachment 3, allow the frame 1 to be obliquely positioned relative to the upper shaft element 6, thereby adjusting to the available slope of the surface adjacent to the lid frame 1.
Sl. 4 kaže izvedbeno obliko z vnaprej pripravljenim delom 19 kot izravnalnim elementom. Po namestitvi tesnila 7, ki spet s svojim nastavkom 8 nalega na čelno stran 9 zgornjega jaškovnega elementa 6 in na štrlino 5, pripravljeni del 19, ki je prirejen obliki cevnega nastavka 3, namestimo na to čelno stran 9. Nastavek 8 pri tem pride v izrez 20 pripravljenega elementa. Zatem spet na zunanjo stran 4 cevnega nastavka 3 nanesemo drsno sredstvo in nato cevni nastavek 3, ki je povezan z okvirom 1 pokrova, spustimo, kot smo pojasnili v zvezi s sl. 3, ga po višini in legi naravnamo in fiksiramo.FIG. 4 shows an embodiment with pre-assembled part 19 as a leveling element. After installing the gasket 7, which again with its nozzle 8 rests on the front side 9 of the upper shaft element 6 and the projection 5, the prepared part 19, which is adapted to the shape of the tubular nozzle 3, is placed on this front side 9. The nozzle 8 thus comes into cutout 20 of the prepared element. Then again, a sliding means is applied to the outer face 4 of the tube nozzle 3 and then the tube nozzle 3 connected to the lid frame 1 is lowered, as explained in connection with FIG. 3, adjust and fix it in height and position.
Pripravljeni del 19 ima reže 21, preko katerih lahko vnesemo malto za izravnavo višine, s čimer opravimo fino nastavitev višine in nagnjenosti okvira pokrova.The prepared part 19 has slots 21 through which a height adjustment mortar can be inserted, thus fine-tuning the height and inclination of the lid frame.
Sl. 6 kaže možnost, da pri spremembi nivoja ceste za manjšo vrednost do okoli 8 cm okvir pokrova prilagodimo novi višini na ta način, da okvir 1 pokrova s primerno dvigalno pripravo dvignemo, pri čemer cevni nastavek 3 v povezavi s tesnilom 7 slejkoprej zagotavlja tesnost.FIG. 6 shows the possibility of adjusting the level of the road for a smaller value of up to about 8 cm to a new height of the lid in such a way that the frame 1 of the lid is raised with a suitable lifting device, the pipe connection 3 in conjunction with the seal 7 being secured in advance.
Če je treba nivo ceste dvigniti za večjo vrednost, je, kot se vidi s sl. 7, možno na že vgreznjeno razporejeni prvotni okvir 1 pokrova namestiti novo tesnilo 7’ in nato vgrezniti nov, s cevnim nastavkom 3’ povezan okvir Γ pokrova in ga naravnati na pravo višino in položaj, pri čemer je tudi v tem primeru zagotovljena potrebna tesnost. Medprostor med starim okvirom 1 pokrova in novim okvirom Γ pokrova lahko pri tem zapolnimo naprimer z gradivom cestne obloge.If the level of the road is to be raised to a higher value, as shown in FIG. 7, it is possible to attach a new gasket 7 'to the already original original lid frame 1, and then insert a new lid lid 3' connected to the tube fitting 3 and adjust it to the correct height and position, providing the necessary tightness in this case as well. The gap between the old cover frame 1 and the new cover frame pri can be filled, for example, with the pavement material.
