This may cause a problem that when one side of the door, that is, the side facing the fire, is heated to the temperature of the fire, such as a high temperature of 1000°C or higher, the other side is maintained at a relatively low temperature, such as Below 40-50℃

Embodiment Construction

[0027] exist figure 1, the schematic diagram shows that a temperature gradient causes a structural member to bend and one side of the structural member is exposed to extremely high temperatures. The structural member indicated by reference numeral 10 has an end wall 12 , a top wall 14 and a side wall 16 . Relative to end wall 12, structural member 10 also has another end wall, relative to top wall 14, structural member 10 also has another bottom wall, relative to side wall 16, structural member 10 also has another side wall, and this side wall exposes In extremely high temperatures, for example, heat is transferred from one side 16 of the structure 10 where the fire causes the temperature to rise to the other side 16, reaching eg 800-1000°C. Thus the other side of the structural member 10 relative to the side wall 16 expands in the direction indicated by a pair of opposing arrows 20 and, conversely, the side wall 16 contracts or contracts relative to the expanded end. The ef...

Abstract

For preventing or reducing temperature gradient caused bending of a structural element made of a material capable of withstanding heating to a specific temperature for an extended period of time, when heating the element to the specific temperature, the structural element is connected to an adjacent supporting structural element through a high temperature resistant supporting body. The structuralelement, providing the high temperature resistant supporting body is provided as a pultruded profiled body including a solidified high temperature resistant resin and reinforcing fibres at least a part of which are constituted by fibres exhibiting high strength and high stiffness at a low temperature and a reduced strength and a reduced stiffness when exposed to and possibly deteriorated at the specific temperature. The structural element is fixated relative to its supporting structure by means of the pultruded body.

Description

technical field [0001] The present invention relates to a novel technique for preventing or reducing temperature gradients that cause buckling of building elements exposed to high temperatures, for example due to a fire on one side of the building elements. Background technique [0002] Many components or building systems have, for example, house buildings have horizontal boundaries, doors, windows, firewalls, ship structures have deck boundaries, baffles, doors, windows, firewalls, etc. One end of the element is physically isolated from the other, thereby preventing a fire (assuming a fire occurs at one end of the building element) from spreading to the other end of the building element. Typically, such building elements are made of steel material, or comprise a steel component fixed to a support member or to another structural member by means of another high temperature resistant and thermally insulating component, such as a steel component of a high temperature tensile, i...
