Definitions

  • the invention relates to a method for monitoring components such as hall roofs, walls, dams od. Like. Especially of cassette roofs on the tightness or moisture and / or temperature, by means of at least one sensor, and a device therefor.
  • components that are exposed to the environment are subject to influences of this environment, especially moisture.
  • moisture is to think of masonry, which sits in the ground or has a connection to the ground. Rising moisture causes the blooming of this masonry and considerable damage. This is especially true in listed buildings and in groundwater changes but also, for example, in penetrating water in dams or bridge structures, especially in game bridges, which are covered on their top with a foil. This film can be destroyed by roots, for example, so that it then comes to a penetration of moisture into the underlying concrete pavement.
  • the term components should be understood very broadly in the present case.
  • a control and reporting system for detecting intrusion of water in buildings wherein at least one moisture or water level sensor is provided in the outer wall of the monitored building area, which is an optical in response to the sensor and / or acoustic signaling signal generating control device is in operative connection.
  • a leak in particular in a flat roof, can be detected in good time before greater damage occurs, and moreover, this damage can be remedied specifically and thus cost-effectively.
  • Such control and reporting systems are only useful if, as with the flat roof, water stops on the roof.
  • the present invention relates primarily to large-scale roofs for industrial and leisure buildings and there especially on large-scale wooden roofs made of cassettes, the transfer of the procedure on steel, light metal and solid roofs is of course possible.
  • the load-bearing construction is usually made of forming laminated beams, also referred to as rafters in sloping roofs, and formed transversely thereto, either launched or used wood structure.
  • This wooden structure is often executed in prefabricated cassette construction. These cassettes span areas of up to 16 m in length and 2.50 m in width.
  • the supporting elements are in turn several in the longitudinal direction of the cassette extending laminated beams.
  • Through a base plate and a cover plate creates a closed volume, which is filled for thermal insulation with insulating material.
  • the base plate is provided on the inside of the cassette with a vapor barrier, the cover plate on the outside with a film to prevent ingress of moisture. On this slide, the roof outer skin is applied.
  • the entire construction thus corresponds to a warm roof in its design, since no ventilation takes place.
  • the present invention has for its object to provide a simple and inexpensive system with which such components could be monitored. SOLUTION OF THE TASK
  • the senor is guided in or on a sensor carrier along predetermined paths in or on the component.
  • tubes are laid in a straight line parallel to one another and preferably terminate in a common channel. From this channel, the sensor carrier is passed through the tubes.
  • pipes with a relatively small diameter of, for example, less than 30 mm in contrast to large pipes, as far as the moisture is concerned, no life of their own. In large pipes, the moisture spreads out, not in small ones. The moisture remains directly in the area of the entry point of the moisture. Of course, this has the advantage that the location of the moisture in a masonry or a roof can be determined much more accurately and quickly.
  • push or pull elements offer as sensor carrier.
  • the insertion of the fiber optic cable is done via appropriate pushing devices, as they are known in the art.
  • the fiber optic cable must have sufficient rigidity with sufficient elasticity and good sliding properties, which is why it is preferably plastic coated.
  • the path for the sensor carrier meanders and is formed by a pipe system.
  • This pipe system has the advantage over an open rail that it clears the way for the sensor carrier, while otherwise insulating material could fall onto the rail.
  • the pipe system should not only be installed in new cassettes, but also existing hall roofs made of cassettes or continuous hall roofs can be retrofitted with the pipe system.
  • the pipe system consists of individual plastic pipes, these can be routed to areas that may be particularly susceptible to moisture.
  • the pipe system only needs to be designed so that the sensor carrier can pass well through the pipe system, especially in the bends.
  • the pipe system or the plastic tube should be configured inside wavy with inner shafts.
  • These inner shafts are said to be the
  • the sensors carried by the sensor carrier should enable the acquisition of moisture, temperature and path data.
  • the path determination is preferably carried out over the rotation of the wheels, whereby a larger slip is excluded by the inner shaft of the tubes. Possibly. It is also possible to use the number of holes in the pipe walls for determining the way.
  • the sensor carrier with a chain drive, wherein the sensor carrier and the chain drive are built very small.
  • the chain drive has the advantage that the small caterpillars have a high contact surface.
  • the corresponding data can be temporarily stored in the sensor carrier and retrieved later. It is also conceivable wireless transmission to a central, so that thereby at the same time the sensor carrier or its path is monitored.
  • the data are reset by an induction coil when entering the corresponding section while detecting the respective sector.
  • the determination of the position is also required in order to obtain an indication of the approximate position of the sensor carrier in the event of a system failure.
  • the recovery can then be carried out, if necessary via inspection openings, by means of a "recovery vehicle” or mechanical aids have a device for docking the recovery vehicle and to unlock his wheels.
  • the sensor carrier itself has a preferably energy self-sufficient drive system, consisting of two or three interconnected via a flexible connection system drive elements that allow him to drive through curves and both simultaneously and individually in both directions can be operated. As a result, the sensor carrier can be moved back when obstacles occur. In case of failure of a drive element, the corresponding wheels are unlocked. Driving on slopes up to 90 ° should be realized in conjunction with the selected type of pipe and lightweight construction. All movements should also be able to be triggered externally via a radio control.
  • the sensor carrier could be placed on a pulling element which pulls it through the pipe system.
  • this tension element could also be designed endless.
  • a chain is installed or retrofitted into the pipe system.
  • This chain can be made of any material, in particular plastic or metal. It is similar to the chain of a sunshade roller blind formed and consists of a plurality of balls, which are arranged on a string. This cord is passed through a channel extending from an inlet to an outlet in the sensor carrier and is placed in the sensor carrier via a pinion of a drive wheel. If this drive wheel is rotated, the pinion runs off the chain, at the same time the sensor carrier is moved along the chain. The sensor carrier pulls on this chain through the entire Pipe system. This avoids the problems of pipe connections, bends, slippage and friction.

It is made of a plurality of Plastic pipes 9 assembled so that straight sections and curved sections can be formed.
