Description

Die Erfindung betrifft eine Brandschutzverglasung aus mehreren in einer gemeinsamen Ebene angeordneten Brandschutzscheiben, mit einer Stütze, die mit Abstand zu der Verglasung freistehend im Raum angeordnet und hierzu an raumbegrenzenden Flächen befestigt ist, wobei die Stütze über eine daran befestigte Tragkonsole mit Brandschutzscheiben verbunden ist, deren Ränder unter Wahrung einer Stoßfuge aneinandergrenzen.The invention relates to fire protection glazing from several in one common level fire screens, with a prop that spaced apart from the glazing and arranged in the room is bounded by space-limiting surfaces, the support being attached to it fortified support bracket is connected to fire screens, the edges adjoin one another while maintaining a butt joint.

Eine solche Brandschutzverglasung ist aus der EP 0 658 677 B1 bekannt. Ein wesentliches statisches Element dieser Brandschutzverglasung ist eine Stützkonstruktion aus einer mit Abstand zu den Brandschutzscheiben frei im Raum angeordneten Metallstütze, die mit ihren Enden an den jeweiligen raumbegrenzenden Flächen befestigt ist. Von der Metallstütze führen Metallkonsolen zu den benachbarten Brandschutzscheiben. An den freien Enden der Konsolen sind diese hierzu mit Stützplatten versehen, welche mit weiteren Stützplatten auf der anderen Seite der jeweiligen Brandschutzscheibe verschraubt sind. Hierbei durchdringt die Verschraubung Bohrungen, mit welchen die Brandschutzscheiben zuvor in ihren Eckenbereichen versehen werden müssen.Such fire protection glazing is known from EP 0 658 677 B1. On An essential static element of this fire protection glazing is a Support structure made of a free space in the room to the fire protection panels arranged metal support with its ends on the respective space-limiting surfaces is attached. Lead from the metal support Metal brackets to the neighboring fire protection panels. At the free ends the consoles are provided with support plates for this purpose, which with other Support plates screwed to the other side of the respective fire protection window are. The screw connection penetrates holes with which the Fire protection panes must first be provided in their corner areas.

Das Herstellen derartiger Bohrungen im Eckenbereich der Brandschutzscheiben ist schwierig, da moderne Brandschutzscheiben mehrlagig mit zwischen Glasschichten angeordneten, einen im Brandfall aufschäumenden Schutzwirkstoff enthaltenden Schichten aufgebaut sind, und Brandschutzscheiben infolge dieses Aufbaus kritisch auf punktförmige mechanische Belastungen reagieren. Besonders empfindlich sind Brandschutzscheiben im Randbereich und hier wiederum im Eckenbereich, weshalb es anzustreben ist, in der Nähe dieser kritischen Zonen auf eine nachträgliche mechanische Bearbeitung soweit als möglich zu verzichten. Von Vorteil bei der Brandschutzverglasung gemäß der EP 0 658 677 B1 ist die sich außerhalb der Verglasungsebene freistehend im Raum befindende Stützkonstruktion. Deren Metallstütze ist im Brandfall einer allseitigen Hitzeeinwirkung ausgesetzt, so daß sie sich im wesentlichen gleichmäßig und ohne größere Verspannungen ausdehnen kann. Infolge dieses weitgehend spannungsarmen Verhaltens lassen sich auch temperaturbedingte Spannungen auf die Brandschutzverglasung gering halten, so daß diese auch bei länger andauernder Einwirkung von Feuer und Hitze keine stärkeren Wölbungen zeigt.The production of such bores in the corner area of the fire protection panes is difficult because modern fire protection panels with multiple layers Glass layers arranged, a foaming protective agent in the event of fire containing layers are built up, and fire protection windows as a result of this React critically to punctiform mechanical loads. Especially Fire protection panes are sensitive in the edge area and here in turn Corner area, which is why it is desirable to be close to these critical zones to avoid subsequent mechanical processing as far as possible. This is advantageous for fire protection glazing according to EP 0 658 677 B1 free-standing in the room outside the glazing level Support structure. In the event of a fire, its metal support is all-round Exposed to heat so that they are substantially uniform and can expand without major tension. As a result of this largely low-stress behavior can also be temperature-related tensions keep fire protection glazing low so that it lasts longer permanent exposure to fire and heat does not show any pronounced bulges.

Der Erfindung liegt die Aufgabe zugrunde, eine sich im Brandfall spannungsarm verhaltende Brandschutzverglasung zu schaffen, bei der kritische mechanische Belastungen im problematischen Rand- und Eckenbereich der Brandschutzscheiben vermieden werden.The object of the invention is to provide fire protection glazing which behaves in a stress-free manner in the event of a fire and in which critical mechanical loads in the problematic edge and corner region of the fire protection panes are avoided.

Zur Lösung dieser Aufgabe wird bei einer Brandschutzverglasung mit den eingangs genannten Merkmalen vorgeschlagen, daß sich in der Stoßfuge ein mit der Tragkonsole verbundenes Distanzstück befindet, auf dem die jeweils oberhalb angeordnete Brandschutzscheibe aufsteht, und daß das Distanzstück auf der der Stütze abgewandten Seite der Verglasung durch eine Platte abgedeckt ist, welche zusätzlich einen Teil des Randes der Brandschutzscheiben überdeckt.To solve this problem, it is proposed in a fire protection glazing with the features mentioned that there is a spacer connected to the support bracket in the butt joint, on which the fire protection pane arranged in each case stands up, and that the spacer on the side of the glazing facing away from the support by a plate is covered, which additionally covers part of the edge of the fire protection panes.

Eine solche Brandschutzverglasung kommt ohne Bohrungen in dem besonders kritischen Rand- und Eckenbereich der beteiligten Brandschutzscheiben aus. Mechanische Spannungsspitzen infolge einer punkt- oder linienförmigen Abführung des beträchtlichen Gewichts der mehrlagigen Brandschutzscheiben werden vermieden. Vielmehr liegt die Brandschutzscheibe mit ihrer Stirn- bzw. Stoßfläche flächig auf einem Distanzstück auf, welches mit der Tragkonsole verbunden ist. Die mechanische Belastung des empfindlichen Randes der Brandschutzscheiben ist hierbei deutlich geringer, als beim Stand der Technik. Zur Aufnahme der Seitenkräfte ist auf der der Stütze abgewandten Seite der Verglasung eine Platte vorgesehen. Indem diese Platte einen Teil des Randes der Brandschutzscheiben überdeckt, werden die seitlichen Kräfte von der Platte über die Tragkonsole auf die Stütze abgeführt. Des weiteren deckt die Platte das Distanzstück ab, so daß dieses zumindest bei einer frontalen Betrachtung der Brandschutzverglasung nicht sichtbar ist.Such fire protection glazing comes without any holes in it critical edge and corner area of the fire protection panes involved. Mechanical stress peaks due to a point or line Removal of the considerable weight of the multi-layer fire protection windows are avoided. Rather, the fire protection window with its front or Flat surface on a spacer, which with the support bracket connected is. The mechanical stress on the sensitive edge of the Fire protection panes are significantly lower than in the prior art. to The side forces are absorbed on the side of the support facing away from the support Glazing provided a panel. By making this plate part of the edge of the Fire protection panes are covered, the lateral forces from the plate the support bracket is led onto the support. The plate also covers that Spacer, so that this at least when viewed from the front Fire protection glazing is not visible.

Gemäß einer bevorzugten Ausgestaltung besteht das Distanzstück aus Holz, vorzugsweise aus schichtverleimtem Holz. Zur Verbesserung der Resistenz gegenüber Feuer kann das Holz in geeigneter Weise vorbehandelt sein, etwa durch eine den Entflammpunkt heraufsetzende Imprägnierung.According to a preferred embodiment, the spacer consists of wood, preferably made of laminated wood. To improve resistance the wood can be suitably pretreated against fire, for example through impregnation that increases the flash point.

Gemäß einer weiteren Ausgestaltung der Brandschutzverglasung ist vorgesehen, daß die Tragkonsole im Querschnitt aus einem Holzkern besteht, der allseitig von Brandschutzplatten umgeben ist. In analoger Weise kann auch die Stütze im Querschnitt aus einem Holzkern bestehen, der allseitig von Brandschutzplatten umgeben ist. In beiden Fällen können aus optischen Gründen die Außenseiten der Brandschutzplatten mit einer Holzverkleidung versehen sein, so daß für den Betrachter der Eindruck einer allein aus Holz bestehenden Stützkonstruktion entsteht.According to a further embodiment of the fire protection glazing, it is provided that that the support bracket in cross section consists of a wooden core, which on all sides of Fire protection panels are surrounded. In an analogous manner, the support in the Cross-section consist of a wooden core, all sides of fire protection panels is surrounded. In both cases, the outer sides of the Fire protection panels with wooden cladding, so that for the The viewer sees the impression of a support structure made entirely of wood arises.

Eine bevorzugte Ausführungsform der Brandschutzverglasung ist gekennzeichnet durch ein Distanzstück in Gestalt eine vierarmigen Kreuzes, wobei jeder der durch die vier Arme definierten Quadranten die Ecke einer Brandschutzscheibe aufnimmt. Zur Verbesserung der mechanischen Stabilität des Distanzstücks wird ferner vorgeschlagen, daß die vier Arme des Distanzstücks von einem gemeinsamen Kern ausgehen.A preferred embodiment of the fire protection glazing is marked through a spacer in the form of a four-armed cross, each of the through the four arms defined quadrants the corner of a fire screen receives. To improve the mechanical stability of the spacer further proposed that the four arms of the spacer be one going out common core.

Gemäß einer weiteren Ausgestaltung ist der Übergang von einem zum nächstfolgenden Arm des Distanzstücks gerundet. Durch eine solche Rundung läßt sich die Festigkeit des Distanzstücks in jenen Bereichen verbessern, in denen die Beanspruchung infolge der Gewichtslast der auf dem jeweiligen Arm sich aufstützenden Brandschutzscheibe besonders groß ist.According to a further embodiment, the transition from one to next arm of the spacer rounded. With such a rounding the strength of the spacer can be improved in those areas where the stress due to the weight load on the respective arm itself supporting fire protection window is particularly large.

Bei Verwendung eines Distanzstücks in Gestalt eines vierarmigen Kreuzes ist es von Vorteil, wenn die Ecken der Brandschutzscheiben angeschrägt sind, vorzugsweise unter 45° in Bezug auf die Ränder der Brandschutzscheibe. Auf diese Weise ist sichergestellt, daß sich die Brandschutzscheibe ausschließlich flächig an bzw. auf einem der Arme des Distanzstücks abstützt, ohne daß es zu mechanischen Belastungen im unmittelbaren Eckenbereich der Brandschutzscheibe kommt.When using a spacer in the form of a four-armed cross, it is an advantage if the corners of the fire protection panes are chamfered, preferably below 45 ° with respect to the edges of the fire protection window. On this way it is ensured that the fire protection window is only is supported flat on or on one of the arms of the spacer without it mechanical loads in the immediate corner area of the Fire protection window is coming.

Mit der Erfindung wird ferner vorgeschlagen, daß die Platte mit der Tragkonsole verschraubt ist. Dies erleichtert die Montage der Brandschutzverglasung. Zunächst wird die aus der Stütze, den Tragkonsolen sowie den Distanzstücken bestehende Stützkonstruktion erstellt. Sodann werden die einzelnen Brandschutzscheiben aufgesetzt, wobei sie durch die Distanzstücke in exakter Beabstandung und Ausrichtung zueinander gehalten werden. Schließlich erfolgt die Sicherung in seitlicher Richtung durch das Aufsetzen der Distanzstücke sowie deren Verschraubung mit der jeweiligen Tragkonsole. Hierbei ist es von Vorteil, wenn gemäß einer weiteren Ausgestaltung der Erfindung die Verschraubung durch eine Bohrung in dem Distanzstück hindurchgeführt ist. Auf diese Weise wird beim Anziehen der Verschraubung das Distanzstück zwischen Tragkonsole und Platte eingespannt.With the invention it is further proposed that the plate with the support bracket is screwed. This facilitates the installation of the fire protection glazing. First becomes that consisting of the support, the support brackets and the spacers Support structure created. Then the individual fire protection panes put on, with the spacers in exact spacing and Alignment to be kept. Finally, the backup is done in lateral direction by placing the spacers and their Screwed to the respective support bracket. It is advantageous here if According to a further embodiment of the invention, the screw connection by a Bore in the spacer is passed. In this way the Tighten the screw connection the spacer between the support bracket and the plate clamped.

Zur eindeutigen Festlegung und Sicherung der Lage und Ausrichtung der Platte in Bezug auf die Tragkonsole wird schließlich vorgeschlagen, daß die Platte an ihrer der Verglasung zugewandten Seite mit Vertiefungen zur teilweisen Aufnahme des Distanzstücks versehen ist. Durch diese Ausgestaltung lassen sich Spalte zwischen Distanzstück einerseits und Platte andererseits vermeiden, wodurch der Abstand zwischen der Stirnseite der Tragkonsole und der Platte vollständig von dem Distanzstück überbrückt wird und damit eine entsprechend große Fläche des Distanzstücks zur Verfügung steht, um darauf die Brandschutzscheibe mit ihrer Stirn- bzw. Stoßfläche abzusetzen.To clearly define and secure the position and orientation of the plate in Regarding the support bracket, it is finally proposed that the plate on its the side facing the glazing with recesses for partially receiving the Spacer is provided. This configuration allows gaps Avoid between the spacer on the one hand and the plate on the other, whereby the Distance between the front of the support bracket and the plate completely from the spacer is bridged and thus a correspondingly large area of the Spacer is available to attach the fire shield with your Remove the front or butt surface.

Die in Fig. 1 dargestellte Brandschutzverglasung dient der lichtdurchlässigen Unterteilung zweier aneinandergrenzender Räume und besteht aus insgesamt neun feststehenden Brandschutzscheiben 1. Bestandteil der Brandschutzverglasung können auch bewegliche und als Türflügel ausgebildete Brandschutzscheiben sein. Eine solche Brandschutzverglasung unter Einbeziehung einer doppelflügeligen Tür ist z. B. in der EP 0 658 677 B1 dargestellt.The fire protection glazing shown in Fig. 1 serves the translucent Subdivision of two adjoining rooms and consists of a total nine fixed fire protection panes 1 Fire protection glazing can also be movable and designed as a door leaf Fire protection glass. Such fire protection glazing under Inclusion of a double leaf door is such. B. in EP 0 658 677 B1 shown.

Um die Brandschutzverglasung zu fixieren, ist diese zunächst entlang der raumbegrenzenden Flächen, d. h. der Wände 2, der Decke 3 sowie dem Boden 4 als im wesentlichen herkömmlich ausgeführte, wandseitige Rahmenkonstruktion 6 ausgeführt. Allein diese wandseitige Rahmenkonstruktion 6 würde der Brandschutzverglasung jedoch noch keine ausreichende Stabilität gegenüber seitlichen Kräften verleihen. Vielmehr sind zusätzlich zwei Stützkonstruktionen unter Verwendung jeweils einer Stütze 7 vorgesehen, wobei jede Stütze 7 mit Ihrem unteren Ende am Boden 4 und mit ihrem oberen Ende an der Decke 3 des Raumes befestigt ist. Die beiden Stützen 7 befinden sich bei der Ausführungsform nach Fig. 1 hinter der eigentlichen Ebene der Verglasung frei im Raum, weshalb die Stützen 7 gestrichelt dargestellt sind.To fix the fire protection glazing, this is first along the space-limiting surfaces, d. H. the walls 2, the ceiling 3 and the floor 4 as a substantially conventional, wall-side frame construction 6 executed. Only this wall-side frame construction 6 would Fire protection glazing, however, still lacks sufficient stability give lateral forces. Rather, there are two additional support structures provided each using a support 7, each support 7 with Its lower end on the floor 4 and its upper end on the ceiling 3 of the Room is attached. The two supports 7 are in the embodiment 1 behind the actual plane of the glazing freely in the room, which is why the supports 7 are shown in dashed lines.

Von den vertikalen Stützen 7 aus erstrecken sich horizontale Tragkonsolen 8 zu jenen Punkten der Verglasung, an denen beim Ausführungsbeispiel die Ecken von insgesamt vier einander benachbarten Brandschutzscheiben 1 aufeinandertreffen. In Fig. 1 ist von jeder Tragkonsole 8 lediglich eine Platte 9 zu erkennen, welche die Tragkonsole an deren Stirnseite abdeckt. Die Ecken der beteiligten Brandschutzscheiben sind hierbei zwischen dieser Platte 9 und der Stirnseite 14 der Tragkonsole 8 eingespannt und auf diese Weise in seitlicher Richtung gesichert.Horizontal support brackets 8 extend from the vertical supports 7 those points of the glazing at which the corners of a total of four adjacent fire protection panels 1 meet. In Fig. 1, only one plate 9 can be seen from each support bracket 8, which the Carrying bracket covers on the front side. The corners of those involved Fire protection panes are between this plate 9 and the end face 14 the support bracket 8 clamped and in this way in the lateral direction secured.

In Fig. 2 sind Einzelheiten der statischen Anbindung der Brandschutzscheiben 1 unter Verwendung der Stütze 7, der Tragkonsole 8, der Platte 9 sowie weiterer, nachfolgend noch näher beschriebener Teile dargestellt.2 shows details of the static connection of the fire protection panes 1 using the support 7, the support bracket 8, the plate 9 and others, parts described in more detail below.

Die Stütze 7 besteht aus einem Kern 10 aus Hartholz, der allseitig mit Brandschutzplatten 11, vorzugsweise auf Basis von Kalzium-Silikat, verkleidet ist. Die Brandschutzplatten 11 wiederum sind aus vor allem ästhetischen Gründen auf ihren Außenseiten mit einer Holzverkleidung 12 versehen. Vorzugsweise ist der Querschnitt der Stütze 7 quadratisch oder rechteckig, jedoch läßt sich in grundsätzlich gleichem Aufbau auch eine runde Holzstütze verwirklichen.The support 7 consists of a core 10 made of hardwood, with all sides Fire protection panels 11, preferably based on calcium silicate, is clad. The fire protection panels 11 are in turn for aesthetic reasons provided on the outside with a wooden panel 12. Preferably, the Cross section of the support 7 square or rectangular, but can be in a round wooden support is basically the same construction.

Der Querschnitt der horizontalen Tragkonsole 8 entspricht im Prinzip dem Querschnitt der Stütze 7. Auch die Tragkonsole 8 setzt sich aus einem Kern 10 aus Hartholz, diesen Kern umgebenden Brandschutzplatten 11 sowie schließlich einer optischen Holzverkleidung 12 zusammen. Auch der Querschnitt der Tragkonsole 8 ist beim Ausführungsbeispiel quadratisch. Die Tragkonsole 8 ist über lange Schrauben 13, die von der Stirnseite 14 der Tragkonsole 8 ausgehen, mit dem Kern der Stütze 7 verschraubt.The cross section of the horizontal support bracket 8 corresponds in principle to that Cross section of the support 7. The support bracket 8 is also composed of a core 10 made of hardwood, this core surrounding fire protection panels 11 and finally an optical wood panel 12 together. The cross section of the Support bracket 8 is square in the embodiment. The support bracket 8 is via long screws 13 which extend from the end face 14 of the support bracket 8, screwed to the core of the support 7.

Fig. 3 zeigt einen Schnitt durch die Tragkonsole 8 mit dem zentralen Kern 10, den Brandschutzplatten 11 sowie der Holzverkleidung 12. Ferner dargestellt ist in gestrichelten Linien ein auf die Stirnseite 14 der Tragkonsole 8 aufgesetztes Distanzstück 15. Das Distanzstück 15 ist in Fig. 2 im Schnitt dargestellt und besteht aus schichtverleimtem Holz, welches vorzugsweise feuerwiderstandsfähig imprägniert ist.Fig. 3 shows a section through the support bracket 8 with the central core 10, the Fire protection panels 11 and the wood cladding 12. Also shown in Dashed lines placed on the end face 14 of the support bracket 8 Spacer 15. The spacer 15 is shown in section in Fig. 2 and consists of laminated wood, which is preferably fire-resistant is impregnated.

Insbesondere Fig. 4, in der das Distanzstück 15 für sich alleine dargestellt ist, zeigt die kreuzförmige Gestaltung des Distanzstücks mit insgesamt vier Armen 16a, 16b, 16c, 16d. Die Breite und Höhe des Distanzstücks 15 entspricht der Breite und Höhe der Tragkonsole 8, an deren Stirnseite 14 das Distanzstück 15 angeordnet ist. Die vier Arme 16a, 16b, 16c,16d des Distanzstücks 15 gehen von einem gemeinsamen Kern 17 aus. Im Bereich des Kerns 17 ist das Distanzstück in der Weise gestaltet, daß der Übergang von einem Arm 16a zum nächstfolgenden Arm 16b nach Art einer Rundung 18 gestaltet ist.4, in which the spacer 15 is shown on its own, shows the cross-shaped design of the spacer with a total of four arms 16a, 16b, 16c, 16d. The width and height of the spacer 15 corresponds to the width and Height of the support bracket 8, on the end face 14, the spacer 15 is arranged is. The four arms 16a, 16b, 16c, 16d of the spacer 15 go from one common core 17 out. In the area of the core 17, the spacer is in the Designed so that the transition from one arm 16a to the next arm 16b is designed in the manner of a curve 18.

Infolge der Arme 16a, 16b, 16c, 16d sind an dem Distanzstück 15 insgesamt acht flache und ebene Anlageflächen 19 für die Brandschutzscheiben der Verglasung ausgebildet. In Fig. 5 ist dargestellt, wie die insgesamt vier an dem Distanzstück 15 zusammentreffenden Brandschutzscheiben 1 in ihrem Eckenbereich an den Anlageflächen 19 des Distanzstücks 15 anliegen. Wichtig ist hierbei, daß die Ecken der Brandschutzscheiben 1 mit Anschrägungen 20 versehen sind. Die Anschrägungen 20 liegen unter einem Winkel von 45° bezüglich der betreffenden Ränder 21 der Brandschutzscheibe 1. Infolge der Anschrägungen 20 kommt es zu keinem Eckenkontakt zwischen den empfindlichen Brandschutzscheiben 1 und dem Distanzstück 15. Vielmehr liegen die Brandschutzscheiben 1 ausschließlich mit ihren gerade verlaufenden Rändern 21 auf den ebenfalls gerade gestalteten Anlageflächen 19 auf, so daß sich eine flächige und nicht linienförmige oder punktförmige Abstützung der empfindlichen Brandschutzscheiben 1 ergibt.As a result of the arms 16a, 16b, 16c, 16d, there are a total of eight on the spacer 15 flat and flat contact surfaces 19 for the fire protection panes of the glazing educated. In Fig. 5 it is shown how the total of four on the spacer 15 meeting fire protection panes 1 in their corner area on the Contact surfaces 19 of the spacer 15 rest. It is important that the Corners of the fire protection panes 1 are provided with bevels 20. The Bevels 20 lie at an angle of 45 ° with respect to the one in question Edges 21 of the fire protection pane 1. As a result of the bevels 20, it occurs no corner contact between the sensitive fire protection panes 1 and the spacer 15. Rather, the fire protection panes 1 are exclusively with their straight edges 21 on the also just designed Contact surfaces 19 so that there is a flat and non-linear or punctiform support of the sensitive fire protection panes 1 results.

Die Dicke der vier Arme des Distanzstücks 15 bedingt die Breite b der Stoßfuge 22 zwischen benachbarten Brandschutzscheiben. Diese Stoßfuge 22 wird nach erfolgter Montage der Brandschutzverglasung mit einer Silikonfüllung verschlossen.The thickness of the four arms of the spacer 15 determines the width b of the butt joint 22 between neighboring fire protection panes. This butt joint 22 is after The fire protection glazing has been installed with a silicone filling locked.

Während die horizontalen und in geringerem Umfang auch die vertikalen Kräfte in der Verglasungsebene über das Distanzstück 15 und die Tragkonsole 8 auf die Stütze 7 abgeführt werden, werden die seitlichen Kräfte einerseits von der Stirnseite 14 der Tragkonsole 8, und andererseits von der Platte 9 aufgenommen. Hierzu ist die Platte 9 mittels der Schraube 23, deren Kopf sich auf der Außenseite der Platte 9 abstützt, mit dem Kern 10 der Tragkonsole 8 verschraubt. Die Schraube 23 ist durch eine Bohrung 24 in der Mitte, d. h. im Kern 17 des Distanzstücks 15 hindurchgeführt.While the horizontal and to a lesser extent the vertical forces in the glazing level on the spacer 15 and the support bracket 8 on the Support 7 are dissipated, the lateral forces on the one hand by the Face 14 of the support bracket 8, and on the other hand received by the plate 9. For this purpose, the plate 9 by means of the screw 23, the head of which is on the outside the plate 9 supports, screwed to the core 10 of the support bracket 8. The Screw 23 is through a bore 24 in the middle, i. H. in core 17 of Spacer 15 passed through.
