VARNOSTNI SISTEM ZA DELO NA STREHIROOF WORKING SYSTEM
Predmet izuma je varnostni sistem za delo na strehi, ki zagotavlja fizično zavarovanje območja ob gradbišču in zagotavlja varnost delavcev pri krovskokleparskih delih, kot to zahtevajo veljavni predpisi za izvajanje gradbenih del na visokih objektih, zlasti na strehah.The subject of the invention is a safety system for roof work, which provides physical protection of the area near the construction site and ensures the safety of workers in roofing works, as required by the applicable regulations for the execution of construction work on high buildings, especially on roofs.
Znano je namreč, da morajo podjetja, ki izvajajo dela na višinah oziroma na strehah, in običajno potekajo razmeroma visoko nad tlemi, zadostiti mnogim predpisom, ki zagotavljajo varnost pri delu in preprečujejo nesreče delavcev.It is well known that companies that perform work at heights or on roofs, and usually run relatively high above the ground, have to comply with many regulations that provide safety at work and prevent workers from accidents.
Tehnični problem, ki ga rešuje navedeni izum, je takšen varnostni sistem za delo na strehi, ki omogoča namestitev lovilne mreže in varnostne ograje, kot to zahtevajo varnostni predpisi, hkrati pa omogoča namestitev pohodnega delovnega odra, ki omogoča hojo po njem in s tem omogoča izvajanje krovsko-kleparskih del, kot so obijanje, letvanje, pokrivanje s kritino, montaža žlebov in obrob.A technical problem solved by the invention is such a safety system for roof work, which allows the installation of trap nets and safety fences, as required by safety regulations, while also allowing the installation of a walkable work platform that allows walking on it and thus performance of roofing and plastering works, such as upholstery, molding, roofing, installation of gutters and edges.
Do sedaj so v ta namen ob zgradbi, na kateri so nameravali izvajati krovsko kleparska dela, postavljali gradbeni oder, na katerem je bila nameščena ograja in zaščitna mreža, ki je delavce na strehi varovala pred padci, prav tako pa je preprečevala padce orodja in drugih predmetov in materialov.Until now, a scaffolding was erected next to the building on which it was intended to perform roofing works, on which a fence and a safety net were installed, which protected workers on the roof from falls, as well as preventing the fall of tools and others. objects and materials.
Postavljanje gradbenih odrov je drago in zahtevno opravilo, poleg tega pa včasih na določenih mestih gradbenega odra sploh ni mogoče postaviti, ker to preprečuje oblika ali lega zgradbe, na kateri se izvajajo krovsko-kleparska dela.Scaffolding is a costly and demanding task, and sometimes it is not possible to place it at certain points in the scaffolding, as this prevents the shape or position of the building on which the roofing and plastering work is carried out.
Eno izmed doslej znano rešitev opisuje patent JP8326252 z naslovom Varnostna ograja za delo na strehi, ki opisuje namestitev zaščitne ograje na rob strehe. Pričvrstitev zaščitne ograje je izvedena z odstranitvijo dela kritine nad nekaterimi nosilnimi elementi ostrešja. Na določene nosilne elemente, ki ležijo na spodnjem oziroma na stranskem robu ostrešja, se po patentu JP8326252 pritrdijo elementi, v katere se kasneje vpenjajo nosilci varnostne ograje. Na te nosilce se pripnejo horizontalni deli varnostne ograje. Rešitev, ki jo navaja patent JP8326252, zagotavlja varnost delavcev na strehi, ne preprečuje pa padanje orodij in drugih predmetov ali materialov in ne omogoča namestitev pohodnega odra, s katerega bi bilo mogoče izvajati krovsko-kleparska dela. Takšna izvedba pa ne omogoča vseh krovsko-kleparskih del, zlasti ne montažo žlebov in obrob.One known solution so far is JP8326252, entitled Roof Work Safety Fence, which describes the installation of a safety fence at the edge of a roof. Securing the guardrail is done by removing a part of the roof over some of the supporting elements of the roof. Certain load-bearing elements lying on the lower or lateral edge of the roof are, according to the patent JP8326252, attached to the elements, into which later the security fence beams are fastened. Horizontal sections of the safety barrier are attached to these supports. The solution cited in JP8326252 provides for the safety of roof workers, but does not prevent tools and other objects or materials from falling and does not allow the installation of a scaffold from which roofing and plastering work can be performed. However, such a design does not allow for all roofing and plastering work, in particular the installation of gutters and edges.
Nekoliko drugačna je rešitev, ki jo opisuje objavljena prijave EP 1215354. Tudi po izumu opisanem v tej patentni prijavi se konstrukcija pričvrsti na konce špirovcev z zgornje strani z ustreznimi vijaki, kar onemogoča, da bi se krovsko-kleparska dela lahko v celoti opravila iz postavljene konstrukcije, saj je za dokončanje krovskokleparskih del potrebno odstraniti postavljeno konstrukcijo. Ker v tej rešitvi potekajo nosilci z zgornje strani, preko delovnega odra, je delovni oder predeljen z vsakim izmed teh nosilcev, kar bistveno zmanjšuje uporabnost le-tega.Somewhat different is the solution described in published applications EP 1215354. Even according to the invention described in this patent application, the construction is fastened to the ends of rafters from above with appropriate screws, which makes it impossible for the roof-plastering work to be completely carried out structures, since the erected structure must be removed to complete the roofing work. Because in this solution, the supports from the top, through the scaffolding, are scaffolded with each of these supports, which significantly reduces the usefulness of the scaffolding.
Rešitev, ki jo navaja predloženi izum za varnostni sistem za delo na strehi v patentnih zahtevkih, zagotavlja z ograjo absolutno varnost za delavce, ki izvajajo dela na strehi in z mrežo preprečuje padce orodja, predmetov in materiala s strehe na območje v okolici, ter s pohodnim delovnim odrom omogoča izvajanje krovskokleparskih del, kot so obijanje, letvanje, pokrivanje s kritino, montaža žlebov in obrob. Sistem je prilagojen tako, da omogoča hitro in enostavno montažo na vidne dele špirovcev v kapu strehe in ob straneh, ter hitro in enostavno demontažo.The solution provided by the present invention for the roofing safety system of the claims provides a fence with absolute safety for workers performing roof work and prevents the fall of tools, objects and materials from the roof into the surrounding area by means of a net. The walkway scaffolding enables the execution of roofing works such as upholstery, molding, roofing, installation of gutters and edges. The system is adapted to allow quick and easy mounting of visible rafters in roof rafters and sides, as well as quick and easy disassembly.

On the existing roof structures we carry out the installation procedure with the help of a ladder or a suitable lift.
V nadaljevanju je s pomočjo izbranega izvedbenega primera varnostnega sistema za delo na strehi še podrobneje opisan izum.In the following, the invention will be described in more detail with the aid of a selected embodiment of a roofing safety system.
Vpenjalna glava 1 je narejena iz dveh med seboj razstavljivih delov, iz svojega prvega in drugega dela.The clamping head 1 is made of two disassembled parts, of its first and second parts.
Prvi del vpenjalne glave 21 je izdelan iz, prednostno kvadratnega, kovinskega profila (tipa A), na katerega je na enem koncu pravokotno privarjena ukrivljena pločevina 22, na katero je na oddaljenosti privarjena matica 23. Skozi matico 23 je vzporedno s pravokotnim profilom 35 vstavljen vijak 23, ki ima na eni strani togo pritrjeno ročico 25 za vrtenje vijaka 24, na drugi strani pa ima drsno vpeto sidrna ploščo 26 z vsaj dvema jeklenima čepoma. Kovinski profil, iz katerega je izdelan prvi del ima vsaj dve luknji 27, skozi katere se prvi del zagozdi z drugim delom 31.The first part of the clamping head 21 is made of a preferably square metal profile (type A), at which a curved sheet 22 is welded at one end to which a nut 23 is welded at a distance. Through a nut 23 is inserted parallel to the rectangular profile 35 a screw 23 having a rigidly mounted handle 25 for rotating the screw 24 on one side and having a sliding anchor plate 26 with at least two steel studs on the other. The metal profile from which the first part is made has at least two holes 27 through which the first part is stuck with the second part 31.
Drugi del vpenjalne glave 31 je izdelan iz takšnega kovinskega profila (tip B), da se kovinski profil (tip A), iz katerega je izdelan prvi del, primemo tesno prilega notranjosti profila, iz katerega je narejen drugi del. Drugi del vpenjalne glave 31 ima iz navedenega profila izdelan križ, z enakimi kraki (32, 35). Na vsakem kraku je izdelana luknja 33, skozi katere se zagozdi, na eni strani s prvim delom vpenjalne glave 21, na drugem koncu pa z nosilno konzolo 2. Pravokotno na tisti krak 34, ki je spet s prvim delov, je na k njemu pravokotna kraka privarjena sidrna plošča 10 iz ukrivljene pločevine, ki je opremljena z več jeklenimi čepi.The second part of the clamping head 31 is made of such a metal profile (type B) that the metal profile (type A) from which the first part is made adheres closely to the interior of the profile from which the second part is made. The second part of the clamping head 31 has a cross made of the same profile with the same arms (32, 35). A hole 33 is made on each arm through which it wedges, on one side with the first part of the clamping head 21 and on the other end with a support bracket 2. Perpendicular to that arm 34, which is again with the first parts, is perpendicular to it. arm welded anchor plate 10 made of curved sheet metal fitted with several steel studs.
Prvi in drugi del vpenjalne glave 1 se prilagodita drug drugemu glede na debelino špirovca 6,7 , na katerega se pritrjuje vpenjalna glava. Po prilagoditvi se čvrsto spneta z zagozdo in zagozdo se zavaruje z varovalko.The first and second parts of the clamping head 1 adjust to each other according to the thickness of the raft 6,7 to which the clamping head is attached. After the adjustment, they are clamped securely with the wedge and the wedge is secured with a fuse.
Nosilna konzola 2 je narejena iz prednostno pravokotnega profila. Na eni strani ima privarjen pod kotom, ki malo večji od pravega, nastavek 17, na katerega se z zagozdo pričvrsti varovalni drog 3. Na drugi strani je nosilna konzola opremljena z dvema enakima, medsebojno togo zvarjenima ploščama 15, ki ga oklepata, nanj pa sta pritrjeni z vijakom 16 tako ,da sta plošči vrtljivi okrog vijaka 16. Med plošče je ob robu privarjen nastavek 40 iz profila (tipa A) s katerim se nosilna konzola 2 spne z vpenjalno glavo 1 s pomočjo zagozde. Po postavitvi nosilne konzole v vodoravno lego, se nosilna konzola 2 fiksira z zagozdo v eno izmed lukenj 14, ki služijo za nastavitev naklona nosilne konzole 2 v vodoravno lego. Nosilni element je mogoče naravnati za naklone streh, ki imajo naklonski kot od 20° do 65°. Na nastavek, ki služi za spenjajne z vpenjalno glavo 1 je privarjen tm 9, ki služi za nameščanje lovilne mreže 5.The support bracket 2 is preferably made of a rectangular profile. On the one hand, it has a weld at an angle slightly larger than the right, a nozzle 17, to which the guard rod is fastened with a wedge 3. On the other hand, the support bracket is provided with two identical, rigidly welded plates 15, which arm it, and therewith they are secured by a bolt 16 so that the plates are rotatable about a bolt 16. Between the plates is welded a profile 40 of profile (type A), which fastens the support bracket 2 to the clamping head 1 by means of a wedge. After placing the support bracket in a horizontal position, the support bracket 2 is fixed by a wedge into one of the holes 14 which serves to adjust the inclination of the support bracket 2 to the horizontal position. The supporting element can be adjusted for roof slopes having an inclination angle of 20 ° to 65 °. A tm 9 is welded to the clamping attachment nozzle 1 for mounting the trap nets 5.
Varovalni drogovi 3 so izdelani iz, prednostno kvadratnega, profila, ki se prilega nastavku 17 na nosilni konzoli 2. Na robu, ki je obrnjen k gradbišču so nanj privarjeni vsaj tri ročice 8, ki so pločevinasti L trakovi, prednostno zgoraj, spodaj in v sredini, tako da omogočajo namestitev lovilne mreže, in varovalne drogove.The guard rods 3 are made of a preferably square profile that fits into the extension 17 on the support bracket 2. At the edge facing the construction site, at least three arms 8 are welded thereto, which are sheet metal L, preferably above, below and in. in the middle, so as to allow the installation of a fishing net, and the safety poles.
