Description

Okenski sestav z ojačitvenimi elementi za prerazporeditev napetostiWindow assembly with reinforcing elements for voltage redistribution

Predlagani izum se nanaša na okenske sestave, še posebej na ojačano leseno okensko ogrodje z ojačitvenim elementom, ki je vgrajen in skrit znotraj lesenega okenskega ogrodja oziroma znotraj lesenega okenskega profila in na postopek izdelave ojačanega lesenega okenskega ogrodja.The present invention relates to window assemblies, in particular to a reinforced wooden window frame with a reinforcing element, which is mounted and hidden within the wooden window frame or within a wooden window profile, and to a process for manufacturing a reinforced wooden window frame.

Pri vgrajevanju okenskih sestavov v predvidene odprtine v zgradbah morajo sestavi izpolnjevati določene predpisane norme, npr. zadostno togost in zadostno odpornost proti obremenitvam z vetrom, če izpostavimo le nekatere. To je še posebej pomembno pri vgradnji lesenih okenskih sestavov velikih dimenzij.When installing window assemblies into the intended openings in buildings, the assemblies must meet certain prescribed standards, e.g. sufficient rigidity and sufficient resistance to wind loads, to name a few. This is especially important when installing large-sized wooden window assemblies.

Tehnični problemA technical problem

Pri velikih okenskih sestavih nastanejo statični problemi zaradi velikih površin, izpostavljenih obremenitvam z vetrom in zaradi povečane lastne teže lesenega okenskega ogrodja, kar lahko povzroči deformacijo lesenega okenskega ogrodja. To je še posebej pomembno pri visokih okenskih sestavih, kjer tehnični problem predstavlja rotacija v kontaktni točki, t.j. v kontaktni točki okenskega ogrodja in konstrukcijo zgradbe ter nezadosten, t.j. nizek vztrajnostni moment prečnega prereza okenskega ogrodja.Large window assemblies cause static problems due to large surfaces exposed to wind loads and due to the increased inherent weight of the wooden window frame, which can cause deformation of the wooden window frame. This is especially important for tall window assemblies where the rotation at the point of contact is a technical problem, i.e. at the window frame contact point and the structure of the building and insufficient, i.e. low cross-sectional inertia of window frame.

Tehnični problem je rešen s predlaganim izumom, ki predstavlja ojačano okensko ogrodje, sestavljeno iz ojačitvenega elementa in lesenega okenskega profila. Ojačitveni element je vgrajen v lesen okenski profil, pri čemer oba konca ojačitvenega elementa segata ven iz lesenega okenskega profila in sta fiksno in neposredno povezana s predvidenimi stenami odprtine v zgradbi. Omenjeno ojačano okensko ogrodje predstavlja konstrukcijsko podporo in povečuje togost okenskih sestavov.The technical problem is solved by the present invention, which is a reinforced window frame consisting of a reinforcing element and a wooden window profile. The reinforcement element is integrated into a wooden window profile, with both ends of the reinforcement element extending out of the wooden window profile and being fixed and directly connected to the intended walls of the opening in the building. This reinforced window frame provides structural support and increases the rigidity of window assemblies.

Lesen okenski okvir je sestavljen iz dveh vertikalnih in dveh horizontalnih obodnih elementov, ki so trdno povezani s konstrukcijo zgradbe, medtem ko vmesni pokončnik predstavlja vertikalni srednji element in vmesni prečnik horizontalni srednji element, ki deli okenski sestav na dva dela. V trenutno znanih okenskih sestavih vmesni pokončni ali prečnik ni neposredno povezan s konstrukcijo zgradbe ampak z obodnimi elementi okenskega okvirja.The wooden window frame consists of two vertical and two horizontal circumferential elements that are firmly connected to the structure of the structure, while the intermediate upright represents the vertical middle element and the intermediate diameter horizontal middle element dividing the window assembly into two parts. In currently known window assemblies, the intermediate upright or diameter is not directly related to the structure of the structure but to the peripheral elements of the window frame.

V tej vlogi izraz leseno okensko ogrodje zaobjema tako vertikalni vmesni del lesenega okenskega okvirja, t.j. vmesni pokončnik, kot horizontalni vmesni del lesenega okenskega okvirja, t.j. vmesni prečnik.In this application, the term wooden window frame encompasses both the vertical intermediate portion of the wooden window frame, i.e. an intermediate upright, as a horizontal intermediate part of a wooden window frame, i.e. intermediate diameter.

V tej vlogi izraz okenski sestav zaobjema tako okna kot drsna vrata.In this role, the term window assembly includes both windows and sliding doors.

Stanje tehnikeThe state of the art

Okno predstavlja gradbeni element, ki je ločeno izdelan in vgrajen v odprtino konstrukcije zgradbe. Tradicionalna zasnova oken predvideva povezavo oken oziroma okenskih okvirjev s konstrukcijo zgradbe z uporabo vijakov ali veznih plošč, odvisno od specifike zgradbe.The window represents a building element that is separately constructed and built into the opening of the structure of the building. Traditional window design involves connecting windows or window frames to the structure of a building using screws or panels, depending on the specifics of the building.

Okenski okvirji in krila so večinoma izdelani iz lesa, aluminija in polimera. V zadnjih letih so okna iz več komornih aluminijastih ali polimernih profilov postala priljubljena zaradi stroškovne učinkovitosti in enostavnosti proizvodnje v primerjavi s tradicionalnimi lesenimi okni. Vsi omenjeni okenski sestavi imajo omejitve zaradi zahtev po odpornosti na obremenitev z vetrom, ki jih določajo mednarodni standardi.The window frames and sash are mostly made of wood, aluminum and polymer. In recent years, multi-chamber aluminum or polymer windows have become popular due to their cost-effectiveness and ease of production compared to traditional wooden windows. All of these window assemblies have limitations due to the requirements for wind load resistance set by international standards.

Okenski sestavi so med življenjsko dobo izpostavljeni različnim obremenitvam. Eden od najpogostejših problemov ob povečevanju velikosti oken je vpliv obremenitve z vetrom in vpliv povečane lastne teže na deformacijo okenskega ogrodja.Window assemblies are exposed to various stresses during their lifetime. One of the most common problems with increasing window size is the impact of wind loads and the impact of increased net weight on the deformation of the window frame.

V ameriškem patentu št. US 6,662,512 B2 je opisana ojačitev v obliki vmesnega pokončnika iz dveh delov, ki predstavlja del celote okenskega sestava in se pretežno uporablja za dvokrilna okna. Kovinski profili se uporabljajo kot prvi člen, na katerega je pritrjen del okenskega okvirja prvega okna in kot drugi člen, na katerega je ravnotako pritrjen del okenskega okvirja drugega okna. Ko je okvir prvega okna povezan z okvirjem drugega okna oba člena skupaj delujeta kot celota. Na takšen način se kovinski profili uporabijo za ojačitev posameznih okenskih elementov in vmesnega pokončnika, ki delujejo kot celota, ko so okna zaprta.In U.S. Pat. US 6,662,512 B2 discloses a two-part intermediate window reinforcement that forms part of the entire window assembly and is predominantly used for double-glazed windows. Metal profiles are used as the first member to which part of the window frame of the first window is attached and as the second member to which the part of the window frame of the second window is equally attached. When the frame of the first window is connected to the frame of the second window, the two articles work together as a whole. In this way, metal profiles are used to reinforce the individual window elements and the intermediate upright, which act as a whole when the windows are closed.

V ameriškem patentu US 5,435,106 A je opisan okenski sestav z okviri iz polimera iz dveh sosednjih oken ter ojačitvenim vmesnim pokončnikom, ki povezuje okni.US Patent 5,435,106 A discloses a window assembly with polymer frames from two adjacent windows and a reinforcing intermediate upright connecting the windows.

Vmesni pokončnik je sestavljen iz dveh votlih polimernih elementov med katerima je kovinska ojačitvena letev spojena z obema polimernima elementoma. Ena kovinska ojačitvena letev ima poseben profil pozicioniran med posameznimi elementi obeh oken z namenom zagotavljanja ojačitve. Dodaten končni element opisan v tem patentu, zagotavlja povezavo z odprtino oz. s konstrukcijo zgradbe, vendar s ciljem zagotavljanja podporne strukture. Stik je zagotovljen z uporabo vijakov, nameščenih znotraj osi vrtenja na kontaktnem mestu, ki pa ne izboljša vztrajnostnega momenta in rotacijske togosti v kontaktnem območju med oknom in okoliško konstrukcijo.The intermediate upright consists of two hollow polymeric elements between which a metal reinforcement strip is connected with both polymeric elements. Each metal reinforcement bar has a special profile positioned between the individual elements of the two windows in order to provide reinforcement. The additional end element described in this patent provides a connection to the opening or opening. with the construction of the structure but with the aim of providing a supporting structure. Contact is ensured by the use of screws mounted inside the axis of rotation at the contact point, which, however, does not improve the moment of inertia and rotational rigidity in the contact area between the window and the surrounding structure.

V CN patentu št. CN106930660 je predstavljena vogalna vez, ki se uporablja za aluminij-les vrata ali okna z namenom zagotovitve dodatne togosti in povezave v kotih oken.In CN patent no. CN106930660 presents a corner link that is used for aluminum-wood doors or windows to provide additional rigidity and connection in window corners.

V omenjenih dokumentih ojačitve predstavljajo del vmesnih pokončnikov, ki pa ne preprečujejo rotacije v kontaktni točki okenskega vmesnega pokončnika in konstrukcije zgradbe. Poleg tega so predstavljene ojačitve posebej izdelane za polimerne ali kovinske okenske profile in zato niso primerne za lesene okenske profile. Poleg tega bi ojačitve, predstavljene v navedenih patentih, negativno vplivale na toplotne lastnosti lesenih okenskih profilov, če bi bila prilagoditev mogoča. Dodatno so vse predstavljene rešitve vidne in niso primerne za lesene okenske profile, pri katerih morajo biti ojačitve skrite v notranjosti lesenih okenskih profilov zaradi estetskega vidika. Okenski sestavi z ojačitvenim elementom za prerazporeditev obremenitve, predstavljeni v tem izumu, zagotavljajo tog stik s konstrukcijo zgradbe, zmanjšano rotacijo v kontaktnem območju in povečanje vztrajnostnega momenta prečnega prereza okenskega ogrodja. Razlika med tradicionalno montažo lesenih okenskih sestavov in predlagano rešitvijo je v dodatnih kontaktnih točkah z gradbeno konstrukcijo, pri čemer je ojačano okensko ogrodje neposredno povezano s konstrukcijo zgradbe, na primer nad in pod okenskim vmesnim pokončnikom, ko je ojačano okensko ogrodje v funkciji vertikalnega vmesenega elementa.In these documents, the reinforcements represent a part of the intermediate uprights, which, however, do not prevent rotation at the contact point of the window intermediate upright and the structure of the building. In addition, the reinforcements presented are specially designed for polymer or metal window profiles and are therefore not suitable for wooden window profiles. In addition, the reinforcements presented in those patents would adversely affect the thermal properties of the wooden window profiles, if adjustments were possible. In addition, all the solutions presented are visible and not suitable for wooden window profiles, where the reinforcements must be hidden inside the wooden window profiles due to the aesthetic aspect. Window compositions with a load redistributive element presented in the present invention provide rigid contact with the structure of the structure, reduced rotation in the contact area, and an increase in the moment of inertia of the cross-section of the window frame. The difference between the traditional assembly of wooden window assemblies and the proposed solution lies in the additional points of contact with the structure, with the reinforced window frame directly connected to the structure of the building, for example above and below the window intermediate window when the window frame is reinforced as a vertical intermediate element. .

Na sliki 4 so prikazani različni prečni prerezi ojačitvenih jeder.Figure 4 shows the different cross sections of the reinforcing cores.

Okenski sestav sestoji iz okenskega okvirja 8 z vsaj enim ojačanim okenskim ogrodjem 1, ki je sestavljeno iz lesenega okenskega profila 2 in ojačitvenega elementa 3, kot je prikazano na sliki 1. Ojačitveni element 3 sestoji iz vsaj enega ojačitvenega jedra 3a, ki je vgrajeno v lesen okenski profil 2 vzdolž celotne dolžine lesenega okenskega profila 2. Oba konca 3c ojačitvenega jedra 3a segata izven lesenega okenskega profila 2 in sta povezana z veznima ploščama 3b, pri čemer je vsaka od omenjenih veznih plošč 3b togo povezana z ustreznim koncem 3c ojačitvenega jedra 3a. Z veznima ploščama 3b je omogočena pritrditev ojačanega okenskega ogrodja 1 v predvideno odprtino zgradbe.The window assembly consists of a window frame 8 with at least one reinforced window frame 1 consisting of a wooden window profile 2 and a reinforcing element 3, as shown in Figure 1. The reinforcing element 3 consists of at least one reinforcing core 3a which is incorporated in a wooden window profile 2 along the entire length of a wooden window profile 2. Both ends 3c of the reinforcing core 3a extend beyond the wooden window profile 2 and are connected to the connecting panels 3b, each of said connecting panels 3b being rigidly connected to the corresponding end 3c of the reinforcing core 3a . The connection panels 3b allow the reinforced window frame 1 to be fixed to the intended opening of the building.

Vezni plošči 3b imata vsaj eno pritrdilno odprtino 4 za povezavo s pritrdilnimi elementi 5, ki zagotavljajo trdno povezavo ojačanega okenskega ogrodja 1 s konstrukcijo zgradbe, t.j. v predvideno steno odprtine v zgradbi. Pritrdilne odprtine 4 so prednostno v obliki okrogle luknje ali utora, vezni plošči 3b pa sta pritrjeni na konstrukcijo zgradbe z uporabo pritrdilnih elementov 5, npr. z vijaki ali z navojnimi palicami z maticami.The connecting plates 3b have at least one fastening opening 4 for connection with the fastening elements 5, which provide a firm connection of the reinforced window frame 1 with the structure of the structure, i.e. into the intended wall of the opening in the building. The mounting openings 4 are preferably in the form of a round hole or groove, and the connecting plates 3b are attached to the structure of the structure using fasteners 5, e.g. with screws or threaded rods with nuts.

V primeru izvedbe, ko je ojačano okensko ogrodje 1 v obliki vmesnega pokončnika, sta vezni plošči 3b povezani s spodnjo steno odprtine 6, t.j. tlemi in z zgornjo steno odprtine 7, t.j. stropom, kot je prikazano na sliki 2.In the embodiment, when the window frame 1 is reinforced in the form of an intermediate upright, the connecting plates 3b are connected to the lower wall of the opening 6, i.e. the floor and with the upper wall of the opening 7, i.e. ceiling as shown in Figure 2.

V primeru izvedbe, ko je ojačano okensko ogrodje 1 v obliki vmesnega prečnika, sta vezni plošči 3b povezani s stranskimi stenami odprtine, t.j. na levo in desno steno odprtine.In the embodiment, when the window frame 1 is reinforced in the form of an intermediate diameter, the connecting plates 3b are connected to the side walls of the opening, i.e. to the left and right wall of the opening.

Ojačitveni element 3 je izdelan iz različnih materialov, na primer iz kovine, ogljikovih vlaken ali steklenih vlaken; prednostno je ojačitveni element 3 izdelan iz kovine. Ojačitveno jedro 3a je prednostno v obliki kovinske letve in ima lahko različne oblike profilov kot so pravokotni profil, L profil, T profil, I profil in H profil, odvisno od velikosti predvidene obremenitve, kot je prikazano na sliki 4. Na primer, pri drsnih vratih je ojačitveno jedro 3a v obliki L profila vstavljeno v lesen okenski profil 2 v bližini zunanje površine lesenega okenskega profila 2, da bi zmanjšali toplotne izgube. Zunanja površina lesenega okenskega profila 2 je površina, ki je ob vgradnji okenskega sestava obrnjena proti zunanjemu prostoru. Na primer, pri dvokrilnem oknu z vmesnim pokončnikom je ojačitveno jedro 3a v obliki pravokotnega profila in je vgrajeno v lesen okenski profil 2. V obeh primerih je ojačitveno jedro 3a ojačitvenega elementa 3 popolnoma skrito v okenskem profilu 2, medtem ko oba konca 3c ojačitvenega jedra 3a segata ven iz lesenega profila 2. Vezni plošči 3b sta prednostno izdelani iz kovine in sta privarjeni na ustrezna konca 3c ojačitvenega jedra 3a, kar zagotavlja trdno povezavo.The reinforcement element 3 is made of a variety of materials, for example metal, carbon fiber or fiberglass; preferably, the reinforcement element 3 is made of metal. The reinforcing core 3a is preferably in the form of a metal strip and may have different profile shapes such as a rectangular profile, L profile, T profile, I profile and H profile, depending on the size of the intended load, as shown in Figure 4. For example, in sliding of the door, an L-shaped reinforcing core 3a is inserted into the wooden window profile 2 near the outer surface of the wooden window profile 2 to reduce heat losses. The outer surface of the wooden window profile 2 is the surface facing the outer space when the window assembly is installed. For example, in the case of a double window with an intermediate window, the reinforcing core 3a is in the form of a rectangular profile and is embedded in a wooden window profile 2. In both cases, the reinforcing core 3a of the reinforcing element 3 is completely hidden in the window profile 2, while the two ends 3c of the reinforcing core 3a extend out of the wooden profile 2. The bonding plates 3b are preferably made of metal and are welded to the corresponding ends 3c of the reinforcing core 3a, which provides a solid connection.

Ojačitveno jedro 3a je vgrajeno v lesen okenski profil 2 z vijačenjem in/ali z lepljenjem.The reinforcing core 3a is incorporated into the wooden window profile 2 by screwing and / or gluing.

V prvi izvedbi se lesen okenski profil 2 ojačanega okenskega ogrodja 1 razteza do okenskega okvirja 8, to je do njegovih navpičnih ali vodoravnih perifernih elementov, kot je prikazano na sliki 3a. V drugi izvedbi se lesen okenski profil 2 ojačanega okenskega ogrodja 1 razteza preko okenskega okvirja 8, kot je prikazano na sliki 3b.In the first embodiment, the wooden window profile 2 of the reinforced window frame 1 extends to the window frame 8, i.e. to its vertical or horizontal peripheral elements, as shown in Figure 3a. In another embodiment, the wooden window profile 2 of the reinforced window frame 1 extends beyond the window frame 8, as shown in Figure 3b.

Postopek izdelave ojačanega okenskega ogrodja 1 sestavljajo naslednji koraki:The process of manufacturing a reinforced window frame 1 consists of the following steps:

- pred izdelava ojačitvenega elementa 3, pri čemer je ustrezen profil ojačitvenega jedra 3a izbran glede na želeno zasnovo okenskega sestava, na vsak konec 3c ojačitvenega jedra 3a pa sta fiksno pritrjeni vezni plošči 3b z oblikovanimi pritrdilnimi odprtinami 4;- prior to the fabrication of the reinforcing element 3, wherein the corresponding profile of the reinforcing core 3a is selected according to the desired design of the window assembly, and to each end 3c of the reinforcing core 3a there are fixed fixing plates 3b with shaped fixing holes 4;

- začetno profiliranje zunanjih površin lesenega okenskega profila 2, ki mu sledi razrez lesenega okenskega profila 2 vzdolž celotne dolžine, pri čemer se določi oblika in položaj utorov glede na izbrano obliko profila ojačitvenega jedra 3a;- initial profiling of the outer surfaces of the wooden window profile 2, followed by cutting the wooden window profile 2 along the entire length, determining the shape and position of the grooves according to the selected shape of the profile of the reinforcing core 3a;

- nanašanje lepila v utor/e;- applying glue to the groove (s);

- vstavljanje pred izdelanega ojačitvenega elementa 3 v utor/e izdelan/e v vsaj enem delu lesenega okenskega profila 2, pri čemer se ojačitveno jedro 3a prilega utoru/om, oba konca 3c ojačitvenega jedra 3a pa segata ven iz lesenega okenskega profila 2;- inserting a pre-fabricated reinforcing element 3 into the groove (s) made in at least one part of the wooden window profile 2, with the reinforcing core 3a fitting into the groove / s and the two ends 3c of the reinforcing core 3a extending out of the wooden window profile 2;

- prekritje vstavljenega ojačitvenega elementa 3, t.j. ojačitvenega jedra 3a z lesenim elementom z obliko in dimenzijami, ki so določene glede na izbrano obliko lesenega okenskega profila 2, obliko profila ojačitvenega jedra 3a in obliko utora, pri čemer je ojačitveno jedro 3a popolnoma vgrajeno v lesen okenski profil 2 in pri čemer oba konca 3c z veznima ploščama 3b segata izven lesenega okenskega profila 2;- covering the inserted reinforcement element 3, i.e. of a reinforcing core 3a with a wooden element having the shape and dimensions determined according to the selected shape of the wooden window profile 2, the shape of the profile of the reinforcing core 3a and the shape of the groove, the reinforcing core 3a being fully integrated into the wooden window profile 2 and having both ends 3c with connecting panels 3b extend beyond the wooden window profile 2;

- stiskanje v stiskalnici, pri čemer je čas stiskanja prilagojen času potrebnemu za zaključitev postopka utrjevanja lepila, s čimer se zagotovi trdna povezava med posameznimi deli, t.j. med ojačitvenim jedrom 3a in lesenim okenskim profilom 2;- pressing in a press, wherein the pressing time is adapted to the time required to complete the process of curing the adhesive, thereby ensuring a firm connection between the individual parts, i.e. between the reinforcing core 3a and the wooden window profile 2;

- dokončanje ojačitvenega okenskega ogrodja 1 z namenom funkcionalne in estetske zaščite lesa in njegove površine.- completion of the reinforcement window frame 1 with the aim of functional and aesthetic protection of the wood and its surface.

Vgradnja okenskih sestavov z ojačanim okenskim ogrodjem 1 se razlikuje od vgradnje standardnih okenskih sestavov. Ojačano okensko ogrodje 1 je potrebno najprej pozicionirati in pritrditi v predvidene stene odprtine zgradbe z uporabo pritrdilnih elementov 5 skozi pritrdilne odprtine 4, ki so izdelane v veznih ploščah 3b. Ojačano okensko ogrodje 1 je nameščeno tako, da povezuje nasprotni strani odprtine v zgradbi, bodisi horizontalni bodisi navpični stranici (steni) odprtine, pri čemer je ojačitveni element 3 povezan s konstrukcijo zgradbe, t.j. pritrjen v predvidene stene odprtine z vijaki, ki so vstavljeni skozi odprtine na veznih ploščah 3b ali z navojnimi palicami z maticami, ki so vstavljene v utore, izdelane na veznih ploščah 3b in zasidrane v konstrukcijo zgradbe.Installation of window assemblies with reinforced window frame 1 differs from the installation of standard window assemblies. The reinforced window frame 1 must first be positioned and secured to the intended walls of the opening of the building by using fasteners 5 through the fastening openings 4 made in the connecting panels 3b. The reinforced window frame 1 is positioned to connect the opposite side of the opening in the building, either horizontally or vertically to the side (wall) of the opening, with the reinforcing element 3 connected to the structure of the building, i.e. secured to the intended walls of the opening by screws inserted through the openings on the connecting plates 3b or by threaded rods with nuts inserted into the grooves made on the connecting plates 3b and anchored in the structure of the structure.

Vgradnjo okenskega sestava z ojačanim okenskim ogrodjem 1 se lahko izvede kot celoten okenski sestav kar pomeni, da je ojačano okensko ogrodje 1 spojeno z okenskim sestavom med postopkom vgradnje, ali kot okenski sestav pri katerem je ojačano okensko ogrodje 1 ločeno od okenskega sestava med postopkom vgradnje.The installation of a window assembly with a reinforced window frame 1 can be carried out as a complete window assembly, which means that the reinforced window frame 1 is connected to the window assembly during the installation process, or as a window assembly where the reinforced window frame 1 is separated from the window assembly during the installation process .

V primeru celotnega okenskega sestava je sestav pozicioniran v odprtino stavbe, ojačano okensko ogrodje 1 pa se trdno poveže s stenami odprtine zgradbe preko veznih plošč 3b s pritrdilnimi elementi 5.In the case of the entire window assembly, the assembly is positioned in the opening of the building, and the reinforced window frame 1 is firmly connected to the walls of the opening of the building via connecting panels 3b with fasteners 5.

V primeru, ko je ojačano okensko ogrodje 1 ločeno od okenskega sestava, se vgradnja začne z vgradnjo ojačanega okenskega ogrodja 1, ki je pozicioniran na ustrezno mesto in trdno povezan s stenami odprtine zgradbe preko veznih plošč 3b s potrditvenimi elementi 5. Preostali del okenskega sestava je nato vstavljen v odprtino in spojen z ojačanim okenskim ogrodjem 1 na znane načine, na primer s posebej oblikovanimi spojnimi elementi.In case the reinforced window frame 1 is separated from the window assembly, installation begins with the installation of the reinforced window frame 1, which is positioned in a suitable place and firmly connected to the walls of the building opening through the connecting panels 3b with the supporting elements 5. The rest of the window assembly it is then inserted into the opening and joined to the reinforced window frame 1 in known ways, for example by specially designed fasteners.

V obeh primerih sledi standardni postopek vgradnje. Okenski okvir 8 je povezan z odprtino zgradbe z vijaki vzdolž okvirja, dodatno pa je nameščen ustrezen montažni material, npr. izolacijska pena, izolacija in trakovi, da je zagotovljena primerna zrakotesnost, prepustnost zraka in vodotesnost spoja.In both cases, the standard installation procedure is followed. The window frame 8 is connected to the opening of the building by screws along the frame, and a suitable mounting material, e.g. insulation foam, insulation and tapes to ensure adequate airtightness, air permeability and watertightness of the joint.

Predlagani izum zagotavlja povezavo med nasprotnimi stranicami (stenami) odprtine zgradbe, zagotavlja povečanje vztrajnostnega momenta prereza ojačanega okenskega ogrodja 1 in zmanjšuje rotacijo ojačanega okenskega ogrodja 1 v kontaktnem področju, t.j. v kontaktni točki okenskega ogrodja 1 s konstrukcijo zgradbe.The present invention provides a connection between opposite sides (walls) of an opening of a building, provides an increase in the moment of inertia of the section of the reinforced window frame 1 and reduces the rotation of the reinforced window frame 1 in the contact area, i.e. at the window frame contact point 1 with the structure of the structure.

Potrebno je izpostaviti, da predloženi izum nikakor ni omejen le na oblike opisane in prikazane na risbah, temveč ustreza tudi katerikoli spremembi ali ekvivalentu v obsegu zahtevkov.It should be noted that the present invention is by no means limited to the forms described and shown in the drawings, but also corresponds to any change or equivalent in the scope of the claims.

Predlagane okenske ojačitve se prednostno uporabljajo za dvokrilne okenske sestave in drsna vrata, vendar so primerne tudi za uporabo v vseh vrstah oken, saj lahko predlagano ojačitev namenjeno prerazporeditvi obremenitev vstavimo v kateri koli okenski element.The proposed window reinforcements are preferably used for double-glazed window assemblies and sliding doors, but are also suitable for use in all types of windows, since the proposed reinforcement for load redistribution can be inserted into any window element.
