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] In Figure 1, the schematic diagram shows that the temperature gradient causes the 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 of the structure 10 to the other side 16 where the fire causes the temperature to rise, 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 effe...

Abstract

In order to prevent or reduce the bending of structural parts caused by temperature gradients, the structural parts are made of materials that can withstand high temperatures for a period of time. When the structural parts are heated to a certain temperature, the structural parts are connected to adjacent supporting members through high-temperature resistant supports superior. A structural member with a high-temperature-resistant support as a stretch-formed body, which includes a high-temperature-resistant solid resin and reinforcing fibers, at least a part of which is composed of fibers exhibiting high-strength and high-hardness properties at low temperatures, and these fibers are exposed to a certain temperature The strength and hardness will be reduced when it is lowered, and it may be damaged. The structural elements are fastened to the supporting elements by means of stretch forming bodies.

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...
