DK153341B - Post profile for internal partition walls - Google Patents

Abstract

A post profile for internal partitions of the type wherein the post profile (1) is designed to support wall boards (2) with an interspacing corresponding to the profile. The profile (1) contains pockets or grooves (3), in which the fire-resisting material (4) is placed. The grooves are preferably placed in the profile's external faces in which cutouts (8) are provided so that the fire-resisting material (4) separates the proper profile (1) from the wall boards (2). The post profile serves to increase the fire-resistance of the partition.

BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a post profile for interior partitions, wherein the post profile is adapted to support wall plates with a distance corresponding to the profile.

DK 153S41B

It has long been known to use metal profiles, preferably steel profiles, as the supporting element in movable partitions of the kind in which a supporting skeleton of pillar profiles positioned at appropriate spacing is used and top and bottom connected by transverse profiles. Outside of said post skeleton, 10 building boards are placed, e.g. plasterboard which is held firmly against the outer surface of the post profile by a joint profile having flanges which engage the abutting ends of the building panels and is arranged to be screwed into the post profile. As a rule, an insulating material, preferably mineral wool, is arranged between the building boards.

In order to meet the requirements of most of the countries with regard to: fire resistance and sound insulating ability, it is necessary in the above known post construction to use at least two layers of conventional building panels in overlapping mounting, which of course substantially increases the total partition compared to previously where a single layer of building plate could be used.

Attempts have been made to solve the problem by placing a layer of non-combustible material on each profile side immediately below the cladding boards, but this solution must be rejected for economic reasons, as an effective fire protection material is very expensive. In addition, in the worst case scenario, the installer fails to place the fire-protective layer on the profile cover and, at best, installs it during large-time consumption.

The invention has for its object to provide a profile which together with a single layer of cladding plate on each side of the profile provides the required fire resistance for 2 years.

the overall wall construction. At the same time, the profile must of course ensure that the design meets the other requirements regarding mechanical strength, sound attenuation, etc. Finally, the profile must be easy to use and install.

This object is achieved according to the invention by a post profile of the kind mentioned above and characterized in that the profile has cross-section rectangular pockets which are arranged to form contact surface for two adjacent wall plates and to receive strips of fire-retardant material.

10 By incorporating fire-retardant material into the profile, a significant increase in the time that the wall structure can insulate a room in which a fire has occurred is obtained from another. The invention is based on the recognition that the weak link in a wall construction of the kind in question in a fire situation is precisely the post profile, since the heat is very rapidly transmitted through the metal and causes a melting of the joint profiles over the wall plates on the wall away from the " heat ”room facing side. Once the assembly profile is melted away, the wall plates bend out and the 20 intermediate insulation disappears, leaving free smoke and flame penetration. By placing the fire-retardant material in the profile itself, a significant delay of the heat transmission is achieved, since the fire-retardant material accumulates the heat and forms resistance to heat transmission, and partly there is no danger of the fire-retardant material being omitted, as it is not without further can be removed from the profile and finally there is no additional mounting. A maximum fire-retardant effect is achieved precisely in the most critical area for the mechanical strength of the wall structure, since the stabilizing wall panels will be held together for as long as possible.

The profile can be substantially M-shaped with pockets for fire-retardant material at the M's sidelines.

With this design great stability is achieved in the profile with regard to compression across the wall structure. In addition, the relatively wide abutment surfaces can be used for retaining a relatively large amount of fire-retardant material and provide compensation for the wall plates.

In addition, the profile may be substantially Z-shaped with pockets for fire-retardant material at the sidelines of the Z.

This embodiment also ensures high mechanical strength against compression and forms broad abutment surfaces for the wall plates.

Cuts may be provided in the outer surfaces of the profile, thereby providing increased resistance to fire, the fire-retardant material being able to counteract radiation and absorb heat directly as the flames will strike against the fire-retardant material through said cuts.

The invention will now be explained in more detail with reference to the drawing, in which: 1 shows the use of a bar profile according to the invention in an oblique view, and FIG. 2 is a horizontal section through the same.

In FIG. 1, the schematic illustration illustrates the principle structure of a partition formed in accordance with the invention. The post profile is generally designated by reference numeral 1 and, in the embodiment shown, is substantially M-shaped. At the lateral bars of the M, bends 5, 6, designed to hold rod-shaped strips 3,4 of fire-retardant material, e.g. raw gypsum. Cutouts 8 are provided at the exterior of the profile so that the profile itself is protected against fire impact. In the center connecting region of the profile, there may also be formed cuts 7 which give rise

5 The wall construction is also of a conventional nature, with wall plates mounted on each side of the post profile, which are assembled to the side surface of the post profile. The wall plates are secured to the post profile by means of a joint profile 9 having the side branches which abut the wall plates and through which fastening screws which are screwed into the post profile are inserted. An insulating material 10, preferably mineral wool, is arranged between the wall plates. In FIG. 2 shows a horizontal section through the embodiment of FIG. 1 is a schematic view of the wall construction, but the wall plates are shown on both sides of the profile 1. In addition, the M-shape of the profile 1 is more clearly visible and the screws passing through the connecting profile 9 are marked by a dash-dotted line. The post profile is preferably of folded steel plate, but other suitable materials can of course also be used. 20 Similarly, as fire-retardant material 3,4, e.g. asbestos foam, raw gypsum, hard pressed mineral wool or a special fire paste that expands by heat. Post bar profile for internal partitions, wherein the bar profile (1) is adapted to carry wall plates (2) with a distance corresponding to the profile, characterized in that the profile (1) has rectangular pockets (5,6) arranged to form a contact surface for two adjacent 30 wall panels and to receive strips (3,4) of fire-retardant material.
