Abstract

The wall profile has two shanks connected by a cross piece with a small cross section to allow easy cutting with snips. The cross piece (8) has an m-shaped tongue (9) with a small ridge (14) formed by a curved section (17). The ridge width is approximately the same as the four times the material width.

Description

Predmetni izum se odnosi na profilni nosač za zvučno-izolacijsku montažnu stijenu, kod kojeg su dva kraka na jednom kraju međusobno povezana poprečnim elementom, koji ima određenu debljinu materijala i kod kojeg je uskim poprečnim presjekom određenog profila omogućeno jednostavno rezanje ručnim škarama. The subject invention relates to a profile support for a sound-insulating mounting rock, in which two arms are interconnected at one end by a transverse element, which has a certain thickness of material and in which the narrow cross-section of a certain profile enables simple cutting with hand scissors.

Profilni nosač se postavlja u montažnu stijenku između dva gornja sloja i svaki od gornjih slojeva naliježe na jedan od krakova i na njega je pričvršćen. Montažna stijena mora jamčiti određenu zvučnu izolaciju, zbog čega se primjerice između obje ljuske zida stavlja izolacioni materijal. Profilni nosač koji je poznat u praksi i koji je uvodno opisan tvori jedan C-profil, kod kojeg poprečni element prema definiciji prolazi relativno ravnolinijski od jednog kraka do drugog. C-profil nema veliki utjecaj na zvučnu izolaciju montažne stijenke. Ipak se C-profilni nosač zbog svog profila može relativno jednostavno obrezati pomoću ručnih škara, pri čemu se prije svega prvo režu oba kraka, tada se poprečni element izvija u visini reza kraka i tada se duž linije savijanja reže poprečni element. The profile support is placed in the assembly wall between the two upper layers and each of the upper layers rests on one of the legs and is attached to it. The assembly wall must guarantee a certain sound insulation, which is why, for example, insulating material is placed between both wall shells. The profile support which is known in practice and which was described in the introduction forms a single C-profile, in which the transverse element, according to the definition, passes in a relatively straight line from one leg to the other. The C-profile does not have a great impact on the sound insulation of the assembly wall. However, due to its profile, the C-profile support can be trimmed relatively easily using hand shears, whereby first of all both legs are cut, then the transverse element is bent at the height of the cut of the leg and then the transverse element is cut along the bending line.

Iz prakse je također poznat profilni nosač za zvučno izolacionu montažnu stijenku, pri kojemu su dva kraka jednim krajem međusobno povezana poprečnim elementom, koji ima određenu debljinu materijala, i kod kojeg poprečni element na jednom M-jezičku tvori široka leda zuba, tako da se kroz taj profil ne može jednostavno rezati ručnim škarama, jer se široka leđa zuba opiru ručnim škarama. Široka poleđina zuba je formirana pomoću dva savijanja bridova i ima širinu poleđine koja je najmanje 6-struka debljina materijala. Taj profilni nosač ima zbog poprečnog elementa na kojem se nalazi M-jezičak bolju zvučno izolacionu funkciju od profilnog nosača s relativno ravnolinijskim poprečnim elementom. A profile support for a sound-insulating prefabricated wall is also known from practice, in which two arms are connected at one end by a transverse element, which has a certain thickness of material, and in which the transverse element on one M-tab is formed by a wide back of teeth, so that through this profile cannot simply be cut with hand shears, because the broad back of the teeth resists hand shears. The broad back of the tooth is formed by two edge bends and has a back width that is at least 6 times the thickness of the material. Due to the transverse element on which the M-tab is located, this profile support has a better sound insulation function than a profile support with a relatively straight-line transverse element.

Zadatak ovog izuma je izvedba uvodno opisanog profilnog nosača, koji zbog mogućnosti jednostavnog rezanja ručnim škarama ima poboljšanu zvučno izolacijsku karakteristiku. Profilni nosač prema izumu kojim se rješava ovaj zadatak je naznačen time, da poprečni element na M-jezičku tvori uska leđa jezička, da je oblikovan samo jednim savijanjem i da ima širinu leđa koja je jednaka maksimalno 4-strukoj debljini materijala. The task of this invention is the performance of the profile support described in the introduction, which, due to the possibility of simple cutting with hand scissors, has improved sound insulation characteristics. The profile support according to the invention, which solves this task, is indicated by the fact that the transverse element on the M-tab forms a narrow back of the tab, that it is formed by only one bend and that it has a width of the back that is equal to a maximum of 4 times the thickness of the material.

Kod profilnog nosača prema izumu je poleđina jezička uska, to znači da je izvedena samo jednim savijanjem i ima širinu leđa koja je jednaka maksimalno 4-strukoj debljini materijala. Uska poleđina jezička povezana s M-jezičcem, dakle sa M-oblikom profila, znatno poboljšava zvučnu izolaciju postignutu pomoću profilnog nosača. Zbog toga što je poleđina jezička uska, a ne samo zbog M-jezička profilni nosač ima bolje zvučno izolaciono djelovanje u montažnoj stijenki. Pri tome postoji mogućnost jednostavnog rezanja ručnim škarama, jer se M-jezičak zbog svojih uskih leđa može zarezati pomoću ručnih škara, nakon čega se polazeći od poleđine jezička mogu rezati djelići jezička. U svemu ostalom rezanje ručnim škarama specijalnog M-profilnog nosača prema izumu vrši se kao i ono poznatog C-profilnog nosača. Uska poleđina jezička je važna kako za bolju zvučnu izolaciju, tako i za jednostavnu mogućnost rezanja ručnim škarama. With the profile support according to the invention, the back of the tongue is narrow, this means that it is made with only one bend and has a width of the back that is equal to a maximum of 4 times the thickness of the material. The narrow back of the tab connected to the M-tab, thus with the M-shape of the profile, significantly improves the sound insulation achieved by means of the profile bracket. Because the back of the tab is narrow, and not only because of the M-tab, the profile bracket has a better sound insulating effect in the assembly wall. There is also the possibility of simple cutting with hand scissors, because the M-tab due to its narrow back can be cut with hand scissors, after which parts of the tab can be cut starting from the back of the tab. In all other respects, the cutting with manual scissors of the special M-profile support according to the invention is done in the same way as that of the known C-profile support. The narrow back of the tab is important both for better sound insulation and for easy cutting with hand scissors.

M-jezičak počinje u visini kraja kraka okrenutog poprečnom elementu kod stope jezička sa dva dijela jezička koji prelaze jedan u drugi na poleđini jezička. Duljina M-jezička koja se pruža od stope jezička prema poleđini jezička iznosi u pravilu najmanje 50% duljine kraka i najviše 100% duljine kraka. Važno je, da je poleđina jezička oblikovana pomoću samo jednog savijanja odnosno izvođenja brida, a ne primjerice pomoću dva međusobno paralelna savijanja. Poleđina jezička je vanjski obris polukružnog prijelaza od jednog dijela jezička prema drugom dijelu jezička, pri čemu širina poleđine jezička približno odgovara promjeru tog polukružnog prijelaza. Pošto M-jezičak sam po sebi uzrokuje slabljenje stabilnosti profilnog nosača, njegovi krakovi imaju na kraju okrenutom suprotno od poprečnog elementa u pravilu savijene rubove, što postoji i kod poznatog C-profilnog nosača i što povećava stabilnost profilnog nosača. The M-tab starts at the height of the end of the arm facing the cross member at the foot of the tab with two parts of the tab that merge into each other on the back of the tab. The length of the M-tab that extends from the base of the tab to the back of the tab is, as a rule, at least 50% of the arm length and at most 100% of the arm length. It is important that the back of the tongue is shaped using only one bending, i.e., the edge, and not, for example, using two parallel bendings. The back of the tongue is the outer outline of the semicircular transition from one part of the tongue to the other part of the tongue, with the width of the back of the tongue approximately corresponding to the diameter of that semicircular transition. Since the M-tab in itself causes a weakening of the stability of the profile support, its arms usually have bent edges at the end facing the opposite of the transverse element, which also exists in the known C-profile support and which increases the stability of the profile support.

U idealnom slučaju se M-jezičak izvodi s uskom poleđinom, pri čemu se poprečni element savija preko elementa s oštrim bridom, tako da se na strani tog elementa za savijanje dobije oštra linija savijanja. Pošto kalup za savijanje iz praktičnih razloga mora biti zaobljen, poleđina jezička, odnosno prijelaz između oba elementa jezička je također na unutarnjoj strani malo zaobljen. Pri tome se preporuča da uski poleđina jezička ima širinu maksimalno jednaku 3-strukoj debljini materijala. Time je poleđina jezička još uža, što dodatno poboljšava zvučnu izolaciju profilnog nosača u montažnoj stijenki i olakšava mogućnost rezanja ručnim škarama. Ideally, the M-tab is made with a narrow back, where the cross member is bent over the sharp edge member, so that a sharp bend line is obtained on the side of the bending member. Since the bending mold must be rounded for practical reasons, the back of the tab, i.e. the transition between both elements of the tab, is also slightly rounded on the inside. At the same time, it is recommended that the narrow back of the tab has a maximum width equal to 3 times the thickness of the material. This makes the back of the tab even narrower, which further improves the sound insulation of the profile support in the assembly wall and facilitates the possibility of cutting with manual scissors.

Ako od uske poleđine jezička polaze dva dijela jezička koja su međusobno postavljena pod kutom od 5-15°, M-jezičak ima povoljan oblik obzirom na apsorpciju zvuka i mogućnost rezanja. Ako poprečni element između jednog od krakova i M-jezička tvori poprečnu zonu pod približno pravim kutom prema kraku, može se jednostavno izvesti uska poleđina jezička i mali kut između elemenata jezička. If two parts of the tongue start from the narrow back of the tongue and are placed at an angle of 5-15°, the M-tab has a favorable shape in terms of sound absorption and the possibility of cutting. If the transverse element between one of the arms and the M-tab forms a transverse zone at an approximately right angle to the arm, a narrow back of the tab and a small angle between the tab elements can be easily achieved.

Preporučiv i svrsishodan oblik izvedbe se dobiva ako M-jezičak duž uske stražnje strane jezička ima niz proboja (otvora), koji se pružaju na dva elementa jezička polazeći od poleđine jezička. Ti proboji koji se pružaju i na elemente jezička također doprinose poboljšanju zvučne izolacije profilnog nosača. Oni olakšavaju rezanje ručnim škarama, jer u području otvora se poleđina jezička ne može rezati, a ručne škare se mogu staviti na jedan od elemenata jezička. A recommended and expedient form of performance is obtained if the M-tab along the narrow back side of the tab has a series of perforations (openings), which extend to the two elements of the tab starting from the back of the tab. These perforations, which also extend to the tongue elements, also contribute to the improvement of sound insulation of the profile support. They facilitate cutting with manual scissors, because in the area of the opening the back of the tab cannot be cut, and manual scissors can be placed on one of the elements of the tab.

Posebno je povoljno i svrsishodno da se, gledajući u smjeru uske poleđine jezička, predvidi povećan broj kratkih proboja, a između svaka dva otvora preostaju kratki mostovi. To poboljšava mogućnosti da se profilni nosač reže na jednom mjestu na kojem nije izvedena uska poleđina jezička. It is especially advantageous and expedient that, looking in the direction of the narrow back of the tongue, an increased number of short openings are foreseen, and short bridges remain between every two openings. This improves the possibilities of cutting the profile bracket in one place where the narrow back of the tab is not made.

Izum se odnosi i na profilni nosač za zvučno-izolacionu montažnu stijenku, kod kojeg su dva kraka na jednom kraju međusobno povezana jednim poprečnim elementom koji ima određenu debljinu materijala i kod kojeg postoji mogućnost kutijastog slaganja dva profilna nosača, pri čemu se jedan krak jednog profilnog nosača uvlači između dva kraka drugog profilnog nosača i nalazi se sasvim uz jedan od ta dva kraka, a naznačen je time, da je poprečni element izveden s jednini M-jezičkom koji tvori poleđinu jezička i koji je pomaknut u odnosu na simetralu nosača i time ima veći razmak od jednog kraka nego od drugog. The invention also relates to a profile support for a sound-insulating assembly wall, in which the two legs are interconnected at one end by one transverse element that has a certain material thickness and in which there is the possibility of stacking two profile supports in a box-like manner, whereby one leg of one profile of the support is inserted between the two arms of the second profile support and is located right next to one of those two arms, and is indicated by the fact that the transverse element is made with a singular M-tab which forms the back of the tab and which is shifted in relation to the bisector of the support and thus has greater distance from one arm than from the other.

Profilni nosač prema ovom izumu uključuje uz zvučnu izolaciju poboljšanu pomoću M-jezička i poboljšanu karakteristiku slaganja, znači mogućnost tješnjeg kutijastog slaganja. Postavljanje M-jezička izvan simetrale može kod izvedbe široke poleđine jezička biti preporučivo, a preporučivo je u kombinaciji s uskom poleđinom jezička. Radi se o profilnom nosaču, kod kojeg je, s jedne strane, uskim poprečnim presjekom određenog profila omogućeno jednostavno rezanje ručnim škarama, a s druge strane postoji mogućnost dobrog kutijastog slaganja kao i slaganja dva profilna nosača jedan na drugi, pri čemu se jedan krak jednog profilnog nosača uvlači između dva kraka drugog profilnog nosača i nalazi se sasvim blizu jednog od ta dva kraka. The profile support according to this invention includes, in addition to sound insulation improved by means of the M-tab, and improved stacking characteristics, meaning the possibility of tighter box stacking. Placing the M-tab outside the bisector can be recommended in the design of the wide back of the tab, and it is recommended in combination with the narrow back of the tab. It is a profile support, where, on the one hand, the narrow cross-section of a specific profile enables easy cutting with hand scissors, and on the other hand, there is the possibility of good box stacking as well as the stacking of two profile supports on top of each other, whereby one arm of one profile of the support is inserted between two arms of the second profile support and is located very close to one of those two arms.

Ovdje spomenuta mogućnost dobrog slaganja profilnog nosača kojom se štedi prostor olakšava skladištenje i transport profilnih nosača, a mogućnost slaganja omogućava produženje jednog profilnog nosača drugim, time što se oba profilna nosača slažu s međusobno preklapajućim krajnjim dijelovima. Dobra mogućnost slaganja pojednostavljuje uzdužno postavljanje profilnih nosača odnosno elemenata profilnih nosača jedan na drugi. U pravilu se M-jezičak postavlja najmanje za pola širine stope jezička pomaknut izvan simetrale. Ta najmanja mjera pomaka od simetrale je nužna za kutijasto slaganje. The mentioned here possibility of good stacking of the profile support, which saves space, facilitates the storage and transport of the profile supports, and the possibility of stacking allows the extension of one profile support by another, by stacking both profile supports with overlapping end parts. A good possibility of stacking simplifies the longitudinal placement of profile supports or profile support elements on top of each other. As a rule, the M-tab is placed at least half the width of the foot of the tab offset from the bisector. That smallest measure of displacement from the bisector is necessary for box stacking.

Naročito je preporučivo i svrsishodno ako oba kraka imaju različitu dužinu. To dopušta slaganje oba profilna nosača s međusobno paralelnim krakovima i poprečnim elementima. Različita dužina krakova je preporučiva i obzirom na to što svaki krak na kraju suprotnom od poprečnog elementa ima savijene rubove. Jedan profilni nosač s kraćim krakom se stavlja ispod savijenog ruba dužeg kraka drugog profilnog nosača. It is especially recommended and expedient if both arms have different lengths. This allows stacking of both profile supports with mutually parallel arms and transverse elements. A different length of the arms is also recommended considering that each arm has bent edges at the end opposite to the transverse element. One profile support with a shorter leg is placed under the bent edge of the longer leg of the second profile support.

Naročito svrsishodno i preporučivo je da se M-jezičak, koji je odmaknut od simetrale, nalazi na razmaku od bližeg kraka najmanje za dužinu prodiranja vijka. Dužina prodiranja vijka, koja se naziva i najmanje prodiranje, predstavlja onaj dio vijka kojim je oplata stijene pričvršćena na krak, koji prodire izvan unutrašnje strane kraka. Vijak ne smije ući u M-jezičak. It is particularly expedient and recommended that the M-tab, which is moved away from the bisector, is located at a distance from the closer leg at least by the length of the screw penetration. The length of bolt penetration, which is also called the smallest penetration, represents that part of the bolt with which the rock formwork is attached to the arm, which penetrates beyond the inner side of the arm. The screw must not enter the M-tab.

Sl. 6 prikazuje oba profilna nosača sa Sl. 3 u prvom složenom stanju. Sl. 6 shows both profile supports from Fig. 3 in the first complex state.

Profilni nosač prema crtežu se ugrađuje prema Sl. 1 u montažnu stijenku, koja ima dvije ljuske 1, koje se postavljaju izvana na jedan od dva kraka 2 profilnog nosača 3. Vijci 4 se uvijaju izvana kroz ljusku 1 i krak 2, a vijak 4 ulazi za dužinu 5 od unutarnje strane kraka u profilni nosač. Na presjeku profilnog nosača je označena simetrala 6. Svaki krak 2 ima na jednom kraju savijeni rub 7 i oba savijena ruba 7 se postavljaju jedan na drugi. Na krajevima suprotnim od savijenih rubova oba kraka 2 prelaze jedan u drugi preko poprečnog elementa 8, koji ima M-jezičak 9. The profile support according to the drawing is installed according to Fig. 1 in the assembly wall, which has two shells 1, which are placed from the outside on one of the two arms 2 of the profile support 3. The screws 4 are screwed from the outside through the shell 1 and the arm 2, and the screw 4 enters the length 5 from the inside of the arm into the profile carrier. The bisector 6 is marked on the section of the profile support. Each leg 2 has a bent edge 7 at one end and both bent edges 7 are placed on top of each other. At the ends opposite the bent edges, both arms 2 pass into each other via the transverse element 8, which has an M-tab 9.

Prema Sl. 2 predviđa se jedan duži krak 2 i jedan kraći krak 2', koji imaju jednako daleko istaknute savijene rubove 7. Poprečni element 8 postavljen nasuprot savijenih rubova 7 tvori na svakom kraku 2, 2' poprečnu zonu 10,10' od koje je dio 10 veći od 10', tako da je M-jezičak 9 pomaknut u odnosu na simetralu 6, to znači da od jednog kraka 2 ima veći razmak nego od drugog kraka 2'. Prema Sl. 4 se profilni nosač 3 za dobro dosjedanje na drugi jednaki profilni nosač 31 postavlja prema drugome na taj način, da krakovi 2, 2' zahvaćaju jedan u drugi sa savijenim rubovima 7 i da je duži krak 2 jednog profilnog nosača 3 okrenut kraćem kraku 2' drugog profilnog nosača 31. Pošto je M-jezičak 9 postavljen izvan sredine, oba M-jezička od oba profilna nosača 3, 31 su postavljena daleko jedan nasuprot drugome. Prema Sl. 4 su oba profilna nosača 3, 31 dobro odnosno praktično postavljena, time da jedan krak 2' jednog profilnog nosača iznutra naliježe na drugi krak 2 drugog profilnog nosača. Pri tome se oba jezička ne dodiruju. According to Fig. 2, one longer arm 2 and one shorter arm 2' are provided, which have bent edges 7 that are equally far apart. The transverse element 8 placed opposite the bent edges 7 forms on each arm 2, 2' a transverse zone 10, 10' of which part 10 larger than 10', so that the M-tab 9 is shifted in relation to the bisector 6, this means that it has a greater distance from one leg 2 than from the other leg 2'. According to Fig. 4, the profile support 3 for a good fit on another equal profile support 31 is placed towards the other in such a way that the arms 2, 2' engage with each other with bent edges 7 and that the longer leg 2 of one profile support 3 faces the shorter leg 2' of the second profile support 31. Since the M-tab 9 is placed outside the middle, both M-tabs of both profile supports 3, 31 are placed far opposite each other. According to Fig. 4, both profile supports 3, 31 are well or practically placed, so that one leg 2' of one profile support lies on the inside of the other leg 2 of the other profile support. In doing so, both tabs do not touch.

Svaki M-jezičak tvori u poprečnoj zoni 10, 10' stopu jezička 11, koja je sastavljena od dva elementa jezička 12, koja su postavljena pod šiljastim kutom 13. Oba elementa jezička 12 prelaze jedan u drugi na kraju postavljenom nasuprot stope jezička 11 preko leđa jezička 14. Prema Sl. 5, leđa jezička 14 imaju širinu leđa 15, koja se mjeri s vanjske strane, i koja je veća od debljine materijala 16 profilnog nosača. Leđa jezička 14 tvore na svojoj unutarnjoj strani relativno jako zakrivljenje 17. Prema Sl. 1 leđa jezička 14 imaju niz kratkih otvora 18, tako da od samih leđa jezička ostaju samo kratki mostovi 19. Otvori 18 su kod ravnog materijala izvedeni probijanjem kao okrugli otvori i pružaju se na elemente jezička 12. Each M-tab forms in the transverse zone 10, 10' a foot of the tongue 11, which is composed of two elements of the tongue 12, which are placed at an acute angle 13. Both elements of the tongue 12 pass into each other at the end placed opposite the foot of the tongue 11 across the back tab 14. According to Fig. 5, the back of the tongue 14 has a back width 15, which is measured from the outside, and which is greater than the thickness of the material 16 of the profile support. The back of the tongue 14 forms a relatively strong curvature 17 on its inner side. According to FIG. 1, the back of the tab 14 has a series of short openings 18, so that only short bridges 19 remain from the very back of the tab. The openings 18 are punched as round openings in flat material and extend to the elements of the tab 12.

Prema Sl. 6 su dva profilna nosača složena jedan u drugi za transport ili skladištenje, to znači tako da se štedi prostor i relativno su labavo gurnuti jedan na drugoga. Kod složenih profitnih nosača, savijeni rub 7 jednog prema van postavljenog kraka 2' jednog profilnog nosača završava ispred susjednog prema unutra postavljenog kraka jednog drugog profilnog nosača. Savijeni rubovi 7 jednog profilnog nosača su postavljeni s razmakom od poprečne zone 10, 10' drugog profilnog nosača. Dok kod kutijasto složenih profilnih nosača prema Sl. 4 duži krak jednog profilnog nosača i kraći krak drugog profilnog nosača moraju biti okrenuti jedan prema drugome, kod profilnih nosača postavljenih jedan na drugi prema Sl. 6 taj položaj može biti proizvoljan, jer kod profilnih nosača postavljenih jedan na drugi prema Sl. 6 također i oba kraća kraja oba profilna nosača i oba duža kraka oba profilna nosača mogu biti okrenuta jedan prema drugome. According to Fig. 6 are two profile supports folded into each other for transport or storage, this means that space is saved and they are relatively loosely pushed on top of each other. In the case of complex profit supports, the bent edge 7 of one outwardly placed leg 2' of one profile support ends in front of the adjacent inwardly placed leg of another profile support. The bent edges 7 of one profile support are placed with a distance from the transverse zone 10, 10' of the other profile support. While in case of box-shaped profile supports according to Fig. 4, the longer leg of one profile support and the shorter leg of the other profile support must face each other, in the case of profile supports placed on top of each other according to Fig. 6, that position can be arbitrary, because in the case of profile supports placed on top of each other according to Fig. 6 also both shorter ends of both profile supports and both longer arms of both profile supports can be turned towards each other.

3. Profile support according to Patent Claim 1 or. 2, characterized by the fact that the narrow back (14) of the tongue has a width (15) maximally equal to 3 times the thickness of the material (16).

4. Profile support according to Patent Claim 1, 2 or 3, characterized by the fact that from the narrow back (14) of the tab, two elements of the tab (12) are placed towards each other at an angle (13) of 5-10°.

5. Profile support according to one of the previous patent claims, characterized in that the transverse element (8) between one of the arms (2, 2') and the M-tab (9) forms a transverse zone (10, 10') approximately perpendicular to the arm .

6. Profile support according to one of the preceding patent claims, characterized in that the M-tab (9) along the narrow back (14) of the tab has a series of perforations (18), which extend to two elements of the tab (12) starting from the back of the tab (14).

7. Profile support for a sound-insulating assembly wall, in which two arms on one side are connected to each other by a transverse element, which has a certain thickness of material, and in which there is the possibility of stacking the profile supports in a narrow box, by inserting one leg of one profile support between two arms of the second profile support and that it fits tightly against one of those two arms, especially according to one of the previous patent claims, characterized by the fact that the transverse element (8) is made with one M-tab (9) that forms the back (14) of the tab , which tab is placed away from the bisector and is therefore at a greater distance from one leg (2) than from the other leg (2').

8. Profile support according to Patent Claim 7, characterized by the fact that the M-tab (9) is moved away from the bisector by at least half the length of the tab (11).

9. Profile support according to Patent Claim 7 or 8, characterized in that both arms (2, 2') have different lengths.

10. Profile support according to Patent claim 7, 8 or 9, characterized in that the M-tab (9) which is moved away from the bisector is located at a distance from the closer arm (2') at least by the length of the penetration of the screw (5).
