DESCRIPTION OF EMBODIMENTS
(5)
(6) As is evident in the schematic diagram of
(7) Closure plate 4 has a line opening 5, which serves to receive and guide line 3. For this purpose, line opening 5 has a cross section that substantially corresponds to the cross section of line 3 and is only slightly larger than this, so that it offers no noteworthy access for combustion gases.
(8) Between the shell surface of line 3 and the inside edge of line opening 5, it is possible to provide a sliding device 6 in the form of a coil of sliding film or of a lubricant, in order to permit sliding of line 3 in the direction of axial extent A of the line or in the ideal case in the direction perpendicular to the face of fire-protection plate 4. Thereby forces and relative movements in axial direction A or perpendicular to the face of the fire-protection plate or perpendicular to the outer face of wall 1, in the event of shaking due to an earthquake or the like, cannot be transmitted from line 3 to fire-protection plate 4. Furthermore, sliding device 6 contributes improved impermeability to gas between line 3 and line opening 5 of closure plate 4.
(9) Closure plate 4 may be made of a flame-resistant or incombustible material, such as filled polyurethane plates, composite materials, e.g. in combination with aluminum or the like.
(10) Closure plate 4 may be constructed in one piece. For simplicity of assembly, however, closure place 2 may also be constructed in multiple pieces with closure-plate parts 41 and 42. A parting line T between two of the closure-plate parts 41, 42 of closure plate 4 extends through line opening 5 in such a way that line opening 5 is formed by closure-plate parts 41, 42, and so closure-plate parts 41, 42 are disposed around line 3. The individual closure-plate parts 41, 42 may then be joined to one another by means of an adhesive or of a joining element 43, so that, even during shaking, caused by an earthquake, for example, these themselves are held against one another, in order to be able to guide line 3 slidingly in line opening 5. The individual closure-plate parts may be additionally modified to have fire-protection capabilities.
(11) Closure plate 4 is equipped with a fastening arrangement 7, which holds closure plate 4 against wall 1, so that the rims or the rim regions of closure plate 4 bear on the regions of wall 1 surrounding passage opening 2. Thereby passage opening 2 is closed impermeably by closure plate 4.
(12) Furthermore, closure plate 4 bears on the regions of wall 1 surrounding passage opening 2 in such a way that, if forces act between closure plate 4 and line 3 transverse (perpendicular) to axial direction A or in surface direction F of wall 1 displacement of closure plate 4 over passage opening 2 is permitted without alteration of the geometry of line opening 5 for receiving line 3 or without exertion of noteworthy forces on line 3.
(13) In order to obtain improved impermeability to gas and sliding ability between closure plate 4 and wall 1, closure plate 4 may be equipped at its rims or its rim regions on the side facing wall 1 with a lubricating and sealing means 8, which seals any access to passage opening 2 between wall 1 and closure plate 4 and at the same time permits movement with less friction of closure plate 4 in surface direction of the wall. Thereby it is ensured in improved manner that the smallest possible forces are transmitted from closure plate 4 to line 3. The lubricating and sealing means may if necessary be mixed with at least one fire-protection additive and/or modified in a manner relevant to fire protection.
(14) Alternatively or additionally, closure plate 4 may be bent over at its rims in the direction of the wall, so that closure plate 3 bears on wall 1 with its rims surrounding passage opening 2. Thereby it is possible to achieve improved impermeability between closure plate 4 and wall 1 and to reduce the surface region for application of lubricating and sealing means 8.
(15) In the illustrated exemplary embodiment, fastening arrangement 7 is provided by means of fastening devices 71. Fastening devices 71 are designed to permit movement in surface direction F of wall 1 and to hold closure plate 4 against movement in axial direction A or perpendicular to surface direction F of closure plate 4 or of wall 1.
(16) In particular, closure plate 4 may be preferably constructed with rectangular shape or else other geometric shapes, and one or more fastening devices 71 may be disposed in its rim region, so that, during attachment of closure plate 4 over passage opening 2, this can be fastened to the regions of wall 1 surrounding passage opening 2. Fastening devices 71 are therefore disposed in such a way that they bear on closure plate 4 mounted on passage opening 2 outside the region of passage opening 2, so that anchoring of fastening devices 71 in wall 1 is possible.
(17) Fastening device 71 comprises a fastening opening 72 in closure plate 4 and a fixation pin 73 to be anchored in the wall. Fixation pin 73 has a much smaller cross section in the region of its shank 75 than does fastening opening 72, so that movement of fire-protection plate 4 transverse to the direction of extent of the fixation pins is possible. Fixation pin 73 is equipped with a fixation head 74, which overlaps fastening opening 72 in closure plate 4 on the side facing away from the wall. By virtue of fixation head 74, closure plate 4 is held against the wall even if this moves laterally relative to fixation pin 73 anchored in the wall.
(18) Fastening openings 72 may be so disposed in closure plate 4 that movement limits defined by the positioning of the shanks of fixation pins 72 in the fastening openings do not cause any of the fastening openings 72 to reach into the region of passage opening 2.
(19) Fixation heads 74 may have cruciate, circular, rectangular or grid-like shape and extend completely or partly over fastening opening 72. In particular, fixation head 74 has a size in the direction transverse to shank 75 of fixation pin 73 that is sufficient to hold closure plate 4 regardless of the position of shank 75 in fastening opening 72.
(20) Preferably, during first assembly, shanks 75 of fixation pins 73 are disposed such that they are situated centrally in fastening openings 73 of closure plate 4 when closure plate 4 is placed on passage opening 2 centrally or with adequate movement limits in all surface directions of wall 1. Thereby it may be ensured that a lateral offset of closure plate 4 relative to fixation pins 73 or relative to passage opening 2 is possible to the same extent in every direction.
(21) By virtue of fastening arrangement 7, it is possible to absorb even lateral movements between wall 1 and line 3 due to the mobility of closure plate 4 along wall 1 or over passage opening 2. The possible displacement path that can be absorbed or compensated for in the event, for example, of an earthquake, may be defined by choosing adequate cross-sectional areas of fastening openings 72 relative to the cross sections of shanks 75 of fixation pins 73. By the fact that closure plate 4 is not buckled or warped during such a displacement, it is able to absorb extremely rapid movements without suffering permanent compression or elongation damage, which could lead to gas leaks.
(22) Fixation head 74 may be equipped with a fire-protection coating, which ensures that fixation pins 72 do not soften due to heat during a fire and thereby jeopardize the fastening of closure plate 4.
