Abstract

A floor component (1) includes a reinforced concrete slab (2) that has a plurality of mutually parallel sheet-meal beams (4), wherein an edge part of each beam (4) is embedded in the slab (2), and wherein a beam web (41) projects out from the slab (2) perpendicularly to said slab and terminates in or connects with a beam flange (5) that includes a part (42) which is bent through 90 DEG relative to the web (41). The first flange part (42) is followed by a second flange part (43) which is bent through 180 DEG over the first flange part (42) and which has a greater width than the first flange part (42).

Description

15 20 25 30 511 897 Vidare är det svårt att på plátbalkarna (dvs deras flänsar) montera beslag för upphångning av profilelement, pà vilka undertak kan monteras. Ändamålet med uppfinningen är att anvisa ett bjâlklagselement av den nämnda arten, vilket har plátbalkar med en utformning som helt eller delvis undanröjer de nämnda problemen. 15 20 25 30 511 897 Furthermore, it is difficult to mount brackets for hanging profile elements on the sheet metal beams (ie their flanges), on which suspended ceilings can be mounted. The object of the invention is to provide a floor element of the said species, which has sheet metal beams with a design which completely or partially obviates the said problems.

Detta ändamål uppnås med ett bjâlklagselement enligt det bilagda patentkravet 1.This object is achieved with a floor element according to the appended claim 1.

Uppfinningen kommer i det följande att beskrivas i exempelform med hänvisning till den bilagda ritningen.The invention will be described in the following in an exemplary form with reference to the accompanying drawing.

I fig 1 och 2 visas ett överhöjt bjälklagselement 1 omfattande en armerad relativt tunn betongplatta 2 med plátbalkar 4 vilka har en randdel ingjuten i betongplattan 2. Plattans 2 armering består av stálfibrer eller konventionella armeringsgitter.Figures 1 and 2 show a raised floor element 1 comprising a reinforced relatively thin concrete slab 2 with sheet metal beams 4 which have an edge part cast into the concrete slab 2. The reinforcement of the slab 2 consists of steel fibers or conventional reinforcing grids.

Vardera plátbalken 4 har ett liv 41 som är orienterat vertikalt och vinkelrätt mot plattans 2 huvudyta. Vid livets 41 undre rand ansluter en balkfläns 5 innefattande ett första flänsparti 42 som är bockat 90° relativt livet 41. Därefter följer ett andra flänsparti som år tillbakabockat runt 180° relativt det första partiet 42 och vilket har en bredd som överstiger bred- den för det första partiet 42. Slutligen är det andra flänspar- tiets 43 randdel 44 omböjt ca 90°bort från plattan 2.Härigenom bildas en át ena sida öppen inträdningsspalt 50 mellan nämnda första och andra flänsparti 42, 43. Dessutom bildas ett upplag 6 på vardera sidan om livet 41, varvid upplagen ligger på väsentligen samma höjdnivå. Härigenom kan en värme- eller ljud- absorberande platta (ej visad) med väsentligen samma bredd som avståndet mellan närliggande plátbalkars 4 liv 41 införas mel- lan dessa och uppbäras på upplagen 6, 6'.Each plate beam 4 has a web 41 which is oriented vertically and perpendicular to the main surface of the plate 2. Adjacent to the lower edge of the web 41 is a beam flange 5 comprising a first flange portion 42 which is bent 90 ° relative to the web 41. Then follows a second flange portion which is bent back 180 ° relative to the first portion 42 and which has a width exceeding the width of the first portion 42. Finally, the edge portion 44 of the second flange portion 43 is bent about 90 ° away from the plate 2. As a result, an entry gap 50 is formed on one side between said first and second flange portions 42, 43. In addition, a support 6 is formed on each side of the waist 41, the supports being at substantially the same height level. As a result, a heat- or sound-absorbing plate (not shown) with substantially the same width as the distance between the webs 41 of adjacent plate beams 4 can be inserted between them and supported on the supports 6, 6 '.

Den del av den undre flânsdelen 43, som ligger under flänsdelen 42, eliminerar helt den laterala rörelsen genom att de båda flänsdelarnas excentriciteter, som uppkommer av kraftflödena, tar ut varandra (neutraliserar varandra).The part of the lower flange part 43, which lies below the flange part 42, completely eliminates the lateral movement in that the eccentricities of the two flange parts, which arise from the force flows, cancel each other out (neutralize each other).

Genom den dubbelvikta flänsen ökar man andelen stål i flänsen relativt livet, och därmed utnyttjas livets skjuvkapacitet 10 15 20 25 511897 4 bättre. Med oförändrad stàlkvantitet kan man erhålla ett styvare och bärkraftigare bjälklag.The double-folded flange increases the proportion of steel in the flange relative to the web, and thus the shear capacity of the web 10 15 20 25 511897 4 is better utilized. With an unchanged quantity of steel, a stiffer and more load-bearing floor can be obtained.

Med hänvisning till fig 3 till 7 kan man se att en i sig förut känd allmänt U-formad upphängningsklammer 7 i sitt liv 71 har en central öppning 72 för en skänkel 83 tillhörande en allmänt U-formad bygel 8, vars andra skänkel 82 har en omböjd änddel 86 (fig 7) vilken har en allmänt V-formad urklippning 85 till bildning av tvâ tänder 84, vilka stöder mot flänsdelens 43 ovansida.Referring to Figs. 3 to 7, it can be seen that a generally known U-shaped suspension bracket 7 in its web 71 has a central opening 72 for a leg 83 belonging to a generally U-shaped bracket 8, the second leg 82 of which has a bent end portion 86 (Fig. 7) which has a generally V-shaped cutout 85 to form two teeth 84 which abut the top of the flange portion 43.

I fig 5 kan man se att öppningen 72 är bildad genom att ett bandformat parti 74 av klammern är stämplad undan frán de när- liggande delarna 75 av klammerns centrala del. I enlighet med en gynnsam utföringsform av uppfinningen är bygelskänkeln 83 försedd med knaster 86, 87 av vilka det främre knastret 86 är avsett att snäppa upp framför bandets 74 främre kant, medan det bakre knastret 87 är anordnat att bilda ett införingsstopp för skänkeln 83 genom öppningen 72. Härigenom kommer klammern 7 att axiellt säkras pà skänkeln 83 som ändå kan demonteras, exempel- vis genom att en skruvmejsel införes mellan bandet 74 och bygel- skänkeln 83 samtidigt som bygeln 8 dras bort från klammern 7.In Fig. 5, it can be seen that the opening 72 is formed by a band-shaped portion 74 of the staple being stamped away from the adjacent portions 75 of the central portion of the staple. According to a favorable embodiment of the invention, the stirrup leg 83 is provided with lugs 86, 87 of which the front crank 86 is intended to snap up in front of the front edge of the belt 74, while the rear crank 87 is arranged to form an insertion stop for the leg 83 through the opening 72. As a result, the clamp 7 will be axially secured on the leg 83 which can still be disassembled, for example by inserting a screwdriver between the belt 74 and the shackle leg 83 at the same time as the shackle 8 is pulled away from the clamp 7.

En klammer 7 av den visade arten tjänar till att emotta en i sig känd s k hattprofil, på vilken innertakplattor sedan kan mOIltêraS .A staple 7 of the type shown serves to receive a so-called hat profile known per se, on which ceiling tiles can then be molded.
