Abstract

Branderfassungs- and -Meldeeinrichtung in particular for a car parking space, comprising a sensor which is embedded in the bottom of the parking space and whose surface is substantially equal in area to the surface of the square.

Description

The invention relates to a Branderfassungs- and -Meldeeinrichtung especially for a car parking space. She goes out of that DE 20 2007 015 924 U1 ,

Because of the rising heat development, fire detectors are placed in the upper part of the room.

From the German Utility Model DE 20 2007 015 924 U1 is known a wall-floor or ceiling covering with a multilayer composite structure, in which a layer, a functional device is integrated, which generates a control command in response to a thermal signal. The covering has a carrier layer facing inward in the insertion position and an outward facing outer layer. A functional element is embedded between the inner and outer layers. In an arrangement in the floor area, the functional element is provided for the regulation of underfloor heating.

Since the thermal signal must first penetrate the outer layer before it can act on the functional element, the known arrangement has an inertia, which makes it appear unsuitable as a fire detector. In addition, a subsequently applied to the ground web-like flooring on a parking space is already unsuitable because of the mechanical stress.

In the DE 10 2015 212 800 A1 For example, a device for measuring the temperature of electrochemical cells in a battery pack is proposed. An infrared sensor is mechanically connected to the battery pack and disposed above the electrochemical cells to detect infrared radiation radiated from the surface of at least one cell.

The sensor is connected to the battery pack, and thus firmly connected to a vehicle, but not to the park. Since not every vehicle is equipped with such a sensor, the park is not always secured.

From the DE 11 2006 001 475 T5 For example, a thermal protector is known comprising a housing, a spring, and a material that holds the spring in a tensioned condition, wherein upon reaching an activation temperature, the material deforms such that the spring relaxes and closes an electrical contact. The device is also known as a thermal jump contact.

Object of the present invention is to propose a delay responsive fire detection device for a park, which also withstands high mechanical stresses.

The object is solved by the features of claim 1.

The inventive Branderfassungs- and -Meldeeinrichtung comprises a sensor which is embedded in the bottom of a particular car parking space and whose surface is substantially equal in area with the surface of the square. In battery-powered electric vehicles, the batteries are generally arranged over a large area under the vehicle floor. It is therefore particularly advantageous to attach the sensor in or on the floor of the car parking space, in such a way that it completes its surface substantially coextensive with the surface of the space. This allows the sensor to be run over without being damaged.

Often parking garages are constructed from prefabricated elements. It is therefore of particular advantage to introduce a receptacle for the sensor or additionally for a reporting line leading from this into the supporting layer, generally a large-area concrete slab, and / or an end layer applied thereon, such as a screed, during its production process.

According to an advantageous embodiment of the invention, a plurality of distributed over the surface of the parking space sensors are provided. Thus, only occasionally emerging heat developments can be detected safely.

The sensor may be an infrared sensor or a bimetal or a snap contact.

According to a preferred embodiment of the invention, the sensors are connected in a star shape or via a bus system with a central detection system. Since the message of each sensor or the sensors of each parking space an address is stamped, the location of the fire can be located immediately.

• 2 einen Schnitt durch die Betonplatte entlang der Schnittlinie II - II in 1.

Further features and advantages of the invention will become apparent from the following description, which explains the invention with reference to an embodiment in conjunction with the accompanying drawings. It shows

• 1 a concrete slab forming the floor of a parking space,
• 2 a section through the concrete slab along the section line II - II in 1 ,

1 shows a concrete floor forming a floor of a parking space 10 in plan view. This has a format that is at least partially of an electric vehicle 12 is covered. About the of the electric vehicle 12 Coverable area are in the concrete slab 10 taken pictures 14 equally distributed. The pictures 14 are via cable channels 16 with the edge 18 the concrete slab 10 connected.

2 shows a section through the concrete slab 10 along the section line II - II in 1 , It can be seen from the drawing that the cable duct 16 inside the concrete slab 10 runs while recording 14 is open to the top. In the latter, an unillustrated sensor can be used. Its connecting cables are through the cable channel 16 led to the outside. When using sensors that transmit their message wirelessly, eliminating the cable channels.
