Description

La présente invention a pour objet une structure de bloc-porte fermant une baie pratiquée dans un ouvrage de maçonnerie installé dans un bâtiment et plus particulièrement dans un bâtiment de haute sécurité tel qu'un bâtiment de centrale nucléaire.The present invention relates to a door block structure closing a bay made in a masonry structure installed in a building and more particularly in a high security building such as a nuclear power plant building.

On sait qu'un bloc-porte est essentiellement constitué, d'une part, par une partie fixe, habituellement connue sous le nom d'huisserie ou de cadre dormant, apte à être engagé(e) dans une ouverture ou baie pratiquée dans un ouvrage de maçonnerie, tel qu'un mur, s'étendant généralement sensiblement verticalement dans un bâtiment en vue de séparer ou de délimiter deux espaces de ce dernier et, d'autre part, par au moins une partie mobile, ci-après dénommée battant, monté(e) pivotant(e) autour d'un axe, généralement sensiblement vertical.It is known that a door block essentially consists, on the one hand, of a fixed part, usually known as a frame or frame, capable of being engaged in an opening or bay made in a masonry structure, such as a wall, generally extending substantially vertically in a building in order to separate or delimit two spaces of the latter and, on the other hand, by at least one movable part, hereinafter referred to as pivoted about an axis, generally substantially vertical.

De manière générale, le cadre dormant, qui présente une forme globalement rectangulaire, est monté et fixé rigidement dans la feuillure de l'embrasure d'une baie, dans laquelle il s'étend sensiblement verticalement, et est composé de deux montants verticaux reliés entre eux par une traverse supérieure horizontale et, éventuellement, d'un seuil, notamment dans le cas d'un bloc-porte étanche formant la partie basse dudit cadre dormant, à l'état monté dans ladite baie. Le battant comporte deux montants opposés, s'étendant sensiblement verticalement à l'état monté du bloc porte dans ladite baie, dont l'un est apte à être monté pivotant sur le montant vertical correspondant du cadre dormant, tandis que l'autre montant opposé du battant est équipé, éventuellement, d'une serrure.In general, the frame, which has a generally rectangular shape, is mounted and fixed rigidly in the rabbet of a recess of a bay, in which it extends substantially vertically, and is composed of two vertical uprights connected between they by a horizontal upper cross and possibly a threshold, particularly in the case of a sealed door block forming the lower part of said frame, in the mounted state in said bay. The leaf has two opposite uprights, extending substantially vertically in the mounted state of the door block in said bay, one of which is adapted to be pivotally mounted on the corresponding vertical upright of the frame, while the other opposite amount the wing is equipped, possibly, with a lock.

Les blocs-portes se répartissent selon plusieurs types de blocs-portes, à savoir les blocs-portes ordinaires, avec ou sans étanchéité à l'air et/ou au feu et/ou au gaz, et les blocs portes coupe feu, avec ou sans serrure, comprenant notamment les blocs-portes pare flammes qui sont étanches au passage des flammes et des gaz, les blocs-portes coupe feu résistant à de fortes élévations de température et les blocs-portes coupe feu étanches à l'air et/ou à l'eau et/ou au gaz.Door units are divided into different types of door units, ie ordinary door units, with or without air and / or fire and / or gas tightness, and fire door blocks, with or without without a lock, including flame-resistant door-blocks that are flame-proof and gas-tight, fire-resistant door locks resistant to high temperature rises, and airtight and / or fire-resistant fire door blocks with water and / or gas.

Dans le cas où les blocs-portes ne comportent pas de serrures, ceux-ci sont plus particulièrement destinés au confinement et au compartimentage des zones enflammées pour empêcher la propagation du feu et des fumées dans les bâtiments ainsi équipés.In the case where the door units do not include locks, they are more particularly intended for containment and compartmentalization of inflamed areas to prevent the spread of fire and smoke in buildings and equipped.

Pour ce qui concerne les bloc-portes destinés à être installés dans des bâtiments de haute sécurité, tels que des bâtiments de centrales nucléaires, ceux-ci doivent répondre à des contraintes de sécurité et/ou de protection incendie élevées. De tels blocs-portes comprennent généralement un battant monté en pivotement sur un cadre dormant au moyen de deux ou trois paumelles munies chacune d'une partie mobile soudée sur l'un des bords verticaux du battant et d'une partie fixe soudée sur l'un des bords verticaux correspondants du cadre dormant.In the case of door units intended to be installed in high security buildings, such as nuclear power plant buildings, these must meet high safety and / or fire protection requirements. Such door blocks generally comprise a leaf pivotally mounted on a frame by means of two or three hinges each provided with a movable part welded to one of the vertical edges of the leaf and a fixed part welded to the one of the corresponding vertical edges of the sleeping frame.

Par ailleurs, ces blocs-portes, lorsqu'ils sont défectueux, dégradés ou endommagés, doivent être changés et remplacés par un bloc-porte identique ou d'un type différent.In addition, these door blocks, when they are defective, degraded or damaged, must be replaced and replaced by an identical door block or of a different type.

D'autre part, un changement de bloc-porte, partiel ou total, peut être prévu lorsque le type de bloc-porte ne convient plus à l'utilisation recherchée, par exemple dans le cas d'un changement de destination d'un local fermé par un bloc-porte ordinaire en un local devant contenir du matériel onéreux ou sensible, comme par exemple du matériel informatique, exigeant une fermeture par un bloc-porte offrant une protection incendie ou plus efficace et plus adaptée tel qu'un bloc coupe feu ou coupe feu étanche.On the other hand, a change of door block, partial or total, can be provided when the type of door block is no longer suitable for the desired use, for example in the case of a change of destination of a local closed by an ordinary door block in a room to contain expensive or sensitive equipment, such as computer equipment, requiring closure by a door block offering fire protection or more effective and more suitable such as a fire block or fireproof cutter.

L'opération qui consiste à enlever un bloc-porte, notamment un bloc-porte installé dans une baie d'un bâtiment hautement sécurisé, est lourde et exige des durées d'intervention longues. En effet, un tel bloc-porte est fixé rigidement avec blocage en position dans la baie correspondante de l'ouvrage de maçonnerie et ne peut être enlevé que par découpage ou tronçonnage, au moyen d'outils spécifiques tels que des meuleuses ou des burineuses. Il en est de même pour l'opération qui consiste à installer un nouveau bloc porte et qui exige une intervention longue incluant la préparation de la surface réceptrice de l'ancien bloc porte et la réalisation de nouvelles soudures pour fixer le nouveau bloc porte. Or, dans ces bâtiments hautement sécurisés, notamment dans les bâtiments de centrales nucléaires, et pour des raisons de sécurité et de protection des opérateurs bien compréhensibles, les temps d'intervention de maintenance et d'immobilisation au coeur des installations doivent être réduits au strict minimum.The operation of removing a door block, including a door block installed in a bay of a highly secure building, is cumbersome and requires long intervention times. Indeed, such a door block is rigidly fixed with locking in position in the corresponding bay of the masonry and can be removed only by cutting or cutting, using specific tools such as grinders or chiselling machines. It is the same for the operation which consists of installing a new door block and which requires a long intervention including the preparation of the receiving surface of the old door block and the realization of new welds to fix the new door block. However, in these highly secure buildings, particularly in nuclear power plant buildings, and for reasons of safety and protection of operators that are easy to understand, maintenance and downtime at the heart of installations must be reduced to the strict minimum. minimum.
