Definitions
- the invention relates to a glass composite unit with at least two panes, a socket consisting of a spacer with a sealing compound and an alarm device with a gas sensor unit arranged in the space filled with gas to signal damage to the glass composite unit in the event of break-in and sabotage.
- So-called alarm spiders are also known, which are formed in a filigree manner from electrically conductive material and are printed on the inside of a pane.
- This Alarm spiders are each in a circuit, the interruption of which triggers an alarm signal.
- Such an interruption is only generated if a glass crack is generated when an attempt is made to destroy a pane, which runs through the area covered by the alarm spider. With normal window glass, this is not guaranteed in every case, so that the corresponding alarm spiders can only be used in connection with special and expensive glasses, for example with glasses that break down into numerous small parts when broken.
- the invention is based on the object of providing a glass composite unit of the type mentioned at the outset which is largely secure against false alarms and which can be used with all types of glass. Furthermore, the safety device is to be installed during the manufacture of the glass composite unit.
- the object is achieved in that there is a gas concentration sensor unit in the gas sensor unit, the response threshold of which is set to a predetermined gas concentration value and emits an alarm signal when the predetermined concentration value is measured.
- the filling gas is first introduced into the space between the at least two panes after the assembly of the glass composite unit with built-in filling gas sensor, the air previously located in the space simultaneously escaping.
- the gas sensor unit is connected to an alarm transmitter or a display device.
- the alarm device or the display device initially shows during filling, that the gas concentration has not yet reached the specified value. If the gas sensor unit is a filling gas sensor unit, it is deactivated when the specified filling gas concentration value is exceeded. If the gas sensor unit is an air sensor unit, it will go below the specified value
- Air concentration value deactivated when the alarm transmitter or the alarm display device becomes inactive, it is signaled that the filling gas has reached the predetermined concentration in the intermediate space. Then additional filling gas is introduced into the intermediate space in order to form a so-called “safety cushion” of filling gas.
- the gas sensor unit not only serves as a security device against burglary and sabotage, but at the same time we are included in the gas filling process. Further refinements result from the subclaims.
- the gas sensor unit consists both of a filling gas sensor unit and one
- Air sensor unit If both sensor units respond, the alarm signal is generated.
- Fig. 1 is a schematic representation of a
- Fig. 2 is a schematic partial view
- Fig. 3 shows another embodiment.
- 1, 1 denotes a glass composite unit.
- Two glass panes 2 are arranged between spacers 3, 4, 5 and 6.
- the spacers 3 to 6 connecting angle elements are designated 7, 8, 9 and 10.
- the spacers 3 to 6 are filled with desiccant 11.
- a sealing compound 12 is provided outside the spacers 3 to 6.
- the air in the intermediate space can also be sucked off with the aid of a pump, not shown.
- a filling gas sensor 15 is attached to the angle element 9, which is provided in the space between the two disks 2 and which is sensitized to a predetermined concentration of the filling gas in a manner not shown.
- Sulfur hexafluoride (SF fi ) with a purity of 4.8 is preferably used as the filling gas.
- the filling gas sensor unit is connected via an electrical connection 16 to an alarm circuit 17, the output of which is connected to an alarm transmitter 18.
- the filling gas sensor is set to a threshold value which responds to a predetermined percentage gas filling in the intermediate space. This response value is sufficiently far from the final percentage gas filling.
- the Filling gas sensor unit 15 in the lower half of the glass composite unit preferably, as shown in FIGS. 1 and 2, attached to the lower angle 9.
- the filling gas is filled through the opening 13. During the filling, the air previously in the intermediate space escapes through the opening 14.
- the filling gas sensor unit 15 is connected to the alarm circuit 17 and activated via the line 16 during the filling process.
- the alarm unit which in this case serves as a test unit, indicates during the filling process by means of a corresponding signal that the desired filling quantity is not yet present in the intermediate space. After filling a predetermined amount of fill gas, the set threshold value of the fill gas sensor unit is reached and exceeded, so that the alarm circuit is deactivated.
- the alarm circuit 17 can be replaced by a test circuit which, however, has essentially the same circuit structure. It is also conceivable that this test circuit acts directly on a pump, not shown, for the filling gas in order to control the filling process. After deactivating the alarm circuit 17 or the test circuit, a predetermined amount of fill gas is introduced into the intermediate space. If the filling gas has "come to rest", then depending on the degree of filling, the filling gas is distributed correspondingly far down from the upper edge of the spacer 3. As a result, a more or less large amount of residual air remains in the lower region, which is in any case below the gas sensor unit 15.
- the filling process can also be done manually, in such a way that after the deactivation of the Alarm circuit or test circuit a predetermined amount of filling gas is filled.
- the alarm circuit 17 or the corresponding test circuit is used twice during the filling process and later in use.
- the filling gas sensor unit can also be designed as an air sensor unit which responds when a predetermined air concentration value, in particular oxygen or nitrogen concentration value, is reached.
- a gas sensor unit 15 * is provided, which consists of a filling gas sensor unit 20 and an air sensor unit 21.
- the filling gas sensor unit 20 is set to a predetermined concentration value of the filling gas.
- the air sensor unit 21 is set to a predetermined concentration value of air, in particular oxygen or nitrogen. Both concentration values are preferably of the same size. However, they can also be different.
- the evaluation circuit 17 ′ has two signal shaping stages 22 and 23, of which the signal shaping stage 22 is assigned to the filling gas sensor unit 20 and the other signal shaping stage 23 to the air sensor unit 21. If the respective concentration value of the filling gas sensor unit 20 and the air sensor unit 21 is reached, a signal is emitted to a logic combination stage 24, which in the sense of a
