Description
Izum se odnosi na držač izolacionog materijala prema vrsti zahtjeva 1. The invention relates to the insulating material holder according to claim type 1.
Iz EP 0 042 573 poznat je držač izolacionog materijala sa šupljom drškom, koji na svom vanjskom kraju ima plitki pridržni tanjur, a na svom unutarnjem kraju ima područje razupiranja s rascjepom, Za učvršćenje izolacione ploče umetne se držač izolacionog materijala u prethodno pripremljenu izbušenu rupu- Zatim se u šuplju dršku ugura klin od sintetičke tvari tako duboko, dok se veza smještena na klinu od sintetičke tvari ne poravna s pridržnim tanjurom- Prethodno se, u ovisnosti o materijalu nosive ljuske, može provesti prilagodba duljine klina kidanjem dijela klina na potrebnom mjestu prijeloma. Svladavanjem graničnika snage udarca koji se pojavljuje uslijed veze na klinu, gurne se držač izolacionog materijala u smjeru nosive ljuske i pritom pritegne izolaciona ploča pridržnim tanjurom. Istovremeno prodire klin od sintetičke tvari u područje razupiranja i proširuje ovo za sidrenje držača izolacionog materijala u nosivoj ljusci. Primjena klina od sintetičnog materijala kod poznatog držača izolacionog materijala ima doduše prednost, da ne nastaje toplinski most; poznati držač izolacionog materijala prikladan je doduše samo za sporedna učvršćenja, budući da klin od sintetičke tvari omogućuje samo male razupiruće sile. lako je prilagodba duljine klina od umjetne tvari moguća u ovisnosti o materijalu osnove sidra, može usprkos tome, ipak radi ukupne duljine klina odgovarajuće držaču izolacionog materijala, nastupiti zbijanje kod njegovog zabijanja u područje razupiranja, koje oštećuje klin od sintetičkog materijala i onemogućuje potpuno zabijanje. Zbog toga je zadaća pronalaska da stvori držač izolacionog materijala, koji se dade montirati jednostavno i bez problema, neovisno o materijalu nosive ljuske, koji ne stvara toplinske mostove i omogućuje kontrolirano sidrenje držača izolacionog materijala u nosivoj ljusci. From EP 0 042 573, a holder for insulating material with a hollow handle is known, which has a shallow retaining plate at its outer end, and a gaping area with a slit at its inner end. Then, a wedge made of synthetic material is pushed into the hollow handle so deeply, until the connection located on the wedge made of synthetic material is aligned with the retaining plate - Previously, depending on the material of the supporting shell, the length of the wedge can be adjusted by tearing a part of the wedge at the required fracture point . By overcoming the shock force limiter that appears due to the connection on the wedge, the holder of the insulating material is pushed in the direction of the supporting shell and the insulating plate is tightened by the holding plate. At the same time, a wedge of synthetic material penetrates the gap area and expands this to anchor the insulating material holder in the supporting shell. The use of a wedge made of synthetic material in the known insulation material holder does have the advantage of not creating a thermal bridge; the known holder of the insulating material is only suitable for secondary fastenings, since the wedge made of synthetic material allows only small bursting forces. it is easy to adjust the length of the wedge made of synthetic material depending on the material of the base of the anchor, however, due to the total length of the wedge corresponding to the holder of the insulating material, compaction may occur when it is driven into the opening area, which damages the wedge made of synthetic material and prevents complete driving. Therefore, the task of the invention is to create an insulating material holder, which can be mounted easily and without problems, independently of the material of the supporting shell, which does not create thermal bridges and enables controlled anchoring of the insulating material holder in the supporting shell.
Rješenje ove zadaće postiže se pomoću držača izolacionog materijala sa značajkama zahtjeva 1. The solution to this task is achieved by means of a holder of insulating material with the features of requirement 1.
Time što je valjčić za zabijanje opremljen rebrom, postiže se, da se valjčić za zabijanje nakon uvođenja u područje tanjura zadrži pritegnuto. Pritom je valjčić za zabijanje zakočen u tanjuru na način, da kod porasta energije zabijanja zahtijevani prijenos sile jamči zabijanje umetka do nalijeganja tanjura na izolacioni materijal, a umetak je fiksiran u izbušenoj rupi. The fact that the nailing roller is equipped with a rib ensures that the nailing roller is kept taut after being introduced into the area of the plate. At the same time, the nailing roller is locked in the plate in such a way that when the nailing energy increases, the required force transfer guarantees the insertion of the insert until the plate rests on the insulating material, and the insert is fixed in the drilled hole.
Nakon nalijeganja pridržnog tanjura sila ponovno znatno poraste, pritom se oslobodi valjčić za zabijanje iz rebra i pomakne u smjeru glave klina. Dosezanjem glave klina uslijedi prijenos energije udaranja direktno na glavu klina. Pritom se klin uklini u područje rascjepa, ovo se proširi i izolaciona ploča pritegne pridržnim tanjurom. Klin dolazi na graničniku za zabijanje do dispozicije. Uspješno razupiranje umetka ja izvedeno tada, kada valjčić za zabijanje leži u šupljoj dršci zabijen do gornjeg ruba tanjura. Izvedbenim oblikom držača izolacionog materijala prema izumu osigura se, da ne dolazi do nastajanja toplinskog mosta. After pressing the retaining plate, the force increases significantly again, at the same time the driving roller is released from the rib and moves in the direction of the head of the wedge. Upon reaching the head of the wedge, the impact energy is transferred directly to the head of the wedge. At the same time, the wedge is wedged into the area of the crack, this expands and the insulating plate is tightened by the retaining plate. The wedge comes on the stop for driving until available. Successful opening of the insert is performed when the hammering roller lies in the hollow shaft and is hammered to the upper edge of the plate. The design of the insulating material holder according to the invention ensures that a thermal bridge does not occur.
Smještanje klina pomoću valjčića za zabijanje ima prednost, što se može primijeniti čelični klin u kratkom obliku izvedbe, a time se postiže u pogledu troškova pogodno učvršćenje. Placement of the wedge by means of a driving roller has the advantage that a steel wedge can be applied in a short version, thereby achieving a cost-effective fastening.
Time što je valjčić za zabijanje proizveden od visokootpornog spojnog materijala i za vrijeme stavljanja može primiti veliku energiju zabijanja bez da se deformira, omogućena je montaža bez problema. The fact that the nailing roller is made of highly resistant connecting material and during installation can receive a large amount of nailing energy without being deformed, enables problem-free installation.
Da bi se osiguralo razupiranje umetka, treba prilagoditi duljinu stršećeg dijela valjčića za zabijanje duljini razupirućeg područja umetka. Zahtijevano razupiranje umetka je zajamčeno tada, ako je valjčić za zabijanje zabijen do gornjeg ruba tanjura. To ensure the spreading of the insert, the length of the protruding part of the nailing roller should be adjusted to the length of the spreading area of the insert. The required opening of the insert is guaranteed if the nailing roller is driven up to the upper edge of the plate.
Konkavna konstrukcija donje strane glave klina pruža prednost, da se vlačna sila koja djeluje na umetak, odvodi preko glave klina u korijen učvršćenja, i ne djeluje više pod pravim kutem, a time ima težnju da raširi umetak, nego silu vodi na vrat vijka, koji sada predstavlja protuležaj za uvedenu silu. Obostrano smještanje rebara na valjčiću za zabijanje osigurava brzo kompletiranje držača izolacionog materijala. The concave construction of the lower side of the pin head offers the advantage that the tensile force acting on the insert is directed over the pin head into the root of the fixture, and no longer acts at a right angle, and thus tends to spread the insert, but directs the force to the neck of the screw, which now represents a counter bearing for the introduced force. The two-sided placement of the ribs on the nailing roller ensures quick completion of the insulating material holder.
Izum se razjašnjava u slijedećem na temelju izvedbenih primjera prikazanih crtežom. The invention is clarified in the following on the basis of practical examples shown in the drawing.

Slika 4 Držač izolacionog materijala u montiranom stanju Figure 4 Insulation material holder in assembled state
Držač izolacionog materijala 1 proizveden prvenstveno od sintetičke tvari sastoji se od plosnatog pridržnog tanjura 2 i šuplje drške 13 cilindričnog vanjskog promjera, koja se na njega priključuje, i koja dalje poprima suženi oblik 15. U šupljoj dršci se nalazi razupirući klin 3 s glavom klina 4, kako to prikazuje slika 1. Na suprotnom kraju od pridržnog tanjura šuplja drška ima prorez 14 i stvara područje razupiranja 12. Na čeonoj strani tanjura smješteni su proboji 19 i ukrućenja 18, da bi se poboljšalo prianjanje žbuke. Donja strana pridržnog tanjura 2 opremljena je okretnim elementima za zatvaranje 17. Na ulazu u šuplju dršku smješten je valjčić za zabijanje 5. The insulating material holder 1, produced primarily from synthetic material, consists of a flat holding plate 2 and a hollow handle 13 with a cylindrical outer diameter, which is connected to it, and which further takes on a narrowed shape 15. In the hollow handle, there is a spreading wedge 3 with a wedge head 4 , as shown in figure 1. At the opposite end of the retaining plate, the hollow handle has a slot 14 and creates a spreading area 12. On the front side of the plate, perforations 19 and stiffeners 18 are placed, in order to improve the adhesion of the plaster. The lower side of the retaining plate 2 is equipped with rotating closing elements 17. At the entrance to the hollow handle, there is a nailing roller 5.
Time što je valjčić za zabijanje 5 na svoja oba kraja opremljen rebrima 6, osigurava se da se valjčić za zabijanje učvršćuje u šuplju dršku 13, stežući se. U rebrima 6 su aksijalno usmjereni prekidi 7, kako to prikazuje slika 2. Specijalni oblik glave klina 4 prikazan je na slici 3. Kao što je vidljivo, donja strana 8 glave klina 4 je konkavno oblikovana. By the fact that the nailing roller 5 is equipped with ribs 6 at both ends, it is ensured that the nailing roller is fixed in the hollow handle 13, clamping. In the ribs 6 there are axially directed breaks 7, as shown in figure 2. The special shape of the head of the wedge 4 is shown in figure 3. As can be seen, the lower side 8 of the head of the wedge 4 is concavely shaped.
Kod zabijanja klina 3 u područje rascjepa 12 gura se klin u smjeru nosive ljuske 28, dok ne nalegne na graničnik zabijanja 26. Pritom se područje rascjepa 12 držača izolacionog materijala raširi i izolacionu ploču pritegne pridržnim tanjurom 2. Istovremeno valjčić za zabijanje 5 leži u šupljoj dršci 13 zabijen do gornjeg ruba pridržnog tanjura, kako prikazuje slika 4, i ispunjava šuplju dršku. When driving the wedge 3 into the gap area 12, the wedge is pushed in the direction of the supporting shell 28, until it rests on the driving stop 26. At the same time, the gap area 12 of the insulating material holder expands and the insulating plate is tightened by the held plate 2. At the same time, the nailing roller 5 lies in the hollow shank 13 driven to the upper edge of the retaining plate, as shown in figure 4, and fills the hollow shank.
