Abstract

Profile for detachable connection between wall elements with tongue and groove, where the wall elements have grooves on their side edges and where the profile is set into the grooves on two adjacent wall elements (5). To make the profile detachable so that any one wall element can be taken out of a constructed wall without necessitating the profile to include costly mobile parts, the profile is assembled with two profile rails (1) with top sections, which are placed with their tabs (3) in connection with one another and the midpieces oriented in opposing directions, as well as two U-shaped cover rails (4), which are placed with one tab on each side of the top section's tab (3).<IMAGE>

Description

DK 152991 BDK 152991 B

Den foreliggende opfindelse angår et samleprofil til adskillelig samling mellem vægelementer med fjer og not og af den i indledningen til kravet angivne art.The present invention relates to an assembly profile for separable assembly between wall elements with feathers and groove, and of the type specified in the preamble to the claim.

Samleprofiler af denne art er kendt fra blandt andet 5 tysk offentliggørelsesskrift nr. 2.747.611. Ved det i dette skrift viste samleprofil er der mellem de to hatteprofiler indlagt en gummitætningsliste, der forhindrer, at der etableres en stiv forbindelse mellem de to hatteprofiler. De to hatteprofiler, der er fremstillet af metal, samvirker derfor ikke 10 som et samlet styrkeelement ved kraftige stødpåvirkninger af væggen/ idet overførelsen af kræfter mellem de to hatteprofiler alene sker gennem de påsatte U-profiler.Collection profiles of this kind are known from, among other things, 5 German Publication Publication No. 2,747,611. In the assembly profile shown in this publication, a rubber sealing strip is inserted between the two hat profiles which prevents a rigid connection between the two hat profiles. Therefore, the two hats made of metal do not cooperate 10 as a total strength element in the strong impact of the wall / the transfer of forces between the two hats profiles only through the applied U-profiles.

Formålet med opfindelsen er på enkel måde at forøge modstandskraften af samleprofilet over for stødpåvirkninger 15 uden tilsvarende at vanskeliggøre adskilleligheden af væggen.The object of the invention is simply to increase the resistance of the joint profile to impacts 15 without correspondingly making the wall separable difficult.

Dette formål opnås ifølge opfindelsen ved, at samle-profilfet er ejendommeligt ved det i krav 1 angivne.This object is achieved according to the invention in that the joint profile grease is peculiar to that of claim 1.

Profileringerne af flangerne muliggør en umiddelbar overførelse af forskydningskræfter mellem de to hatteprofi-20 ler uden om de to U-formede dækskinner. Dækskinnerne behøver derfor ikke at blive forsynet med særlige låseorganer, hvilket forenkler adskillelsen af samleprofilet betydeligt.The profiling of the flanges enables an immediate transfer of shear forces between the two cap profiles around the two U-shaped tire rails. Therefore, the tire rails do not need to be provided with special locking means, which greatly simplifies the separation of the assembly profile.

Opfindelsen skal i det følgende beskri Mes. nærmere under henvisning til tegningen, i hvilken der er vist et udføre!-25 seseksempel på profilet ifølge opfindelsen. I tegningen vi ser :The invention will now describe Mes. Referring now to the drawing, in which an exemplary embodiment of the profile according to the invention is shown. In the drawing we see:

Fig. 1 et snit gennem et profil ifølge opfindelsen, fig. 2 et vandret snit i en væg, hvor profilet ifølge opfindelsen er indsat i noter i sidekanterne i to 30 vægelementer, og fig, 3 et afsnit af profilet ifølge opfindelsen med en krog til aftagning af en dækskinne indsat.FIG. 1 is a section through a profile according to the invention; FIG. 2 is a horizontal section of a wall in which the profile according to the invention is inserted into grooves in the side edges of two wall elements, and fig. 3 is a section of the profile according to the invention with a hook for removing a cover rail inserted.

Det i fig. 1 i tværsnit viste profil ifølge opfindelsen består af to profilskinner 1 med hatteprofil. Profilskinnerne 35 1 består således af et U-formet midterparti 2 og to flige 3, der er forbundet med midterpartiet ved de yderste enaer af benene i U-formens ben. De to profilskinner 1 er anbragt i anlæg mod hinanden således at de U-formede midterpartier er orienteret modsat. Derved kommer fligene 3 til at ligge anThe FIG. 1 in cross section according to the invention consists of two profile rails 1 with a hat profile. Thus, the profile rails 35 1 consist of a U-shaped central portion 2 and two tabs 3 connected to the central portion at the outer ends of the legs of the U-shaped legs. The two profile rails 1 are arranged in abutment so that the U-shaped central portions are oriented opposite. This causes the tabs 3 to touch

2 mod hinanden to og to. De to par flige holdes sammen ved hjælp af dækskinner 4. der er U-formede og som presses ind over de mod hinanden anliggende flige. De to profiiskinner og de to dækskinner danner derved tilsammen et lukket profil.2 against each other two and two. The two pairs of tabs are held together by tire rails 4. which are U-shaped and which are pressed over the adjacent tabs. The two profile rails and the two tire rails thereby together form a closed profile.

5 der er egnet til indsættelse i noter i sidekanter i op til hinanden stødende sidekanter af to vægelementer således som det er vist i fig. 2, der viser et vandret snit gennem en væg, der er sammensat af lodrette vægelementer 5.5 suitable for insertion into grooves in side edges of adjacent side edges of two wall elements as shown in FIG. 2, which shows a horizontal section through a wall composed of vertical wall elements 5.

En stivere og stærkere udformning fremkommer, hvis der i 10 fligene 3 oppresses et fremspring 6 i den ene af fligene og en tilsvarende fordybning 7 i den anden flig. Nér de to profilskinner 1 bringes i anlæg mod hinanden og den ene af profilskinnerne 1 endevendes, vil fremspringet 6 passe ind i fordybningen 7, hvorved de to profilskinner forhindres i at 15 blive forskudt i forhold til hinanden. Den klemvirknmq, som dækskinnerne 4 skai præstere, bliver derved reduceret til blot at være tilstrækkelig til at dæksk i nnerne ikke kan falde af af sig selv. Dette arrangement gør samlingen af profilet til en meget enkel proces og det samme gælder adskilleisen. 20 Den lette adskillelse kan udnyttes ved udtagning af et væge lement 5 i en væg. Udtagningen sker ved at dæksk i nnerne 4 aftages på begge sider af profilerne 1 i de to samlinger på elementets- 5 to sider, hvorefter elementet kan udtages, idet profilskinnerne forbliver i noterne i vægelementerne. For at 25 lette aftagningen af dæksk i nnerne kan disse være forsynet med i det mindste en udtagning i forbindelsespartiet mellem dæksk innernenes flige som vist ved 8 på fig. 3. Ved indsættelse af en krog 9 i udtagningen kan dækskinnen let trækkes af, især hvis udtagningen er placeret forholdsvis tæt ved en af 30 enderne af dækskinnen. Genopsætning af et udtaget vægelement sker ved at påsætte dækski nnerne på de hatteformede profil-skinner 1 efter at vægelementet er bragt på plads i væggen. For at lette påsætningen af dækskinnerne kan disse ved enderne have fligene bøjet en smule udefter så fligene på profil-35 skinnerne lettere fanges, hvorefter dæksk i nnerne presses på plads og derved låser profilet sammen igen omtrent som en lynlås.A stiffer and stronger configuration emerges if a tab 6 is pressed into one of the tabs in one of the tabs and a corresponding recess 7 in the other tab. When the two profile rails 1 are brought into contact with each other and one of the profile rails 1 is turned, the projection 6 will fit into the recess 7, thereby preventing the two profile rails from being displaced relative to each other. The clamping effect provided by the tire rails 4 is thereby reduced to just being sufficient that the tire in the nails cannot fall off by itself. This arrangement makes the assembly of the profile a very simple process and so does the separation requirement. The easy separation can be utilized by removing a wick element 5 in a wall. The removal is done by removing the cover in the nails 4 on both sides of the profiles 1 in the two joints on the two sides of the element, after which the element can be removed, leaving the profile rails in the grooves in the wall elements. In order to facilitate the removal of tires in the nails, these may be provided with at least one recess in the connecting portion between the tire flaps of the tires as shown at 8 in FIG. 3. When inserting a hook 9 into the recess, the tire rail can be easily pulled off, especially if the recess is located relatively close to one of the 30 ends of the tire rail. Removing a removed wall element is done by applying the cover rails to the hat-shaped profile rails 1 after the wall element is placed in the wall. To facilitate the attachment of the tire rails, these at the ends may have the tabs bent slightly outward so that the tabs on the profile rails are more easily caught, after which the tire in the nails is pressed in place, thereby locking the profile together again approximately like a zipper.

Midterdelen af prof i iski nnerne bidrager kun i ringe grad ' til profilets styrke og stivhed, fordi denne del af profilet 3The middle part of the profile in the scissors contributes only slightly to the strength and stiffness of the profile, because this part of the profile 3

er placeret forholdsvis tæt ved den neutrale akse af profilet. Den del af midterpartierne, som er indsat i vægelementerne kan derfor med fordel perforeres, hvilket reducerer såvel varme- som lydtransmissionnen gennem 5 profilet. Det er navnlig af hensyn til brandrnodstanden af den samlede væg bestående af vægelementer og profiler vigtigt at profilerne ikke virker som forbindelsesbroer gennem væggen for varme udviklet ved en eventuel brand. Dersom der anbringes perforeringer i fligene skal disse placeres således 10 at der ikke opstår utætheder gennem profilet.is located relatively close to the neutral axis of the profile. The portion of the central portions inserted in the wall elements can therefore advantageously be perforated, which reduces both the heat and the sound transmission through the profile. In particular, in view of the fire resistance of the entire wall consisting of wall elements and profiles, it is important that the profiles do not act as connecting bridges through the wall for heat developed in the event of a fire. If perforations are placed in the tabs, they must be positioned such that no leaks occur through the profile.

De af profilskinner og dækskinner sammensatte profiler er enkle at fremstille, idet de enkelte dele lader sig valse op af f.eks. tynd stålplade. Dækskinnerne lukker profilet, således at der ikke er mulighed for lydgennemgang, når profilet 15 er indsat i noterne i vægelementerne i en skillevæg. Desuden virker profilerne afstivende på væggen på grund af det forholdsvis store i ner timoment, som prof iIski nnerne på grund af hatteprofilet besidder.The profiles made up of profile rails and tire rails are easy to manufacture, as the individual parts can be rolled up by e.g. thin steel plate. The tire rails close the profile so that no sound penetration is possible when the profile 15 is inserted into the grooves in the wall elements of a partition. In addition, the profiles appear to be stiffened on the wall due to the relatively large momentum that the ProfiIs have due to the hat profile.
