    The invention relates to a method for marking and locating a measuring point in a cast concrete ceiling, wherein the formwork for the concrete pavement will provide a marking body for the measuring point imaged on the formwork before the concrete pavement is poured, and to a device for carrying out the method.
    For the air conditioning of rooms, it is known to embed heat exchangers from tube coils, which are combined by spacer holders into area registers, for a heat carrier into the concrete floor. These area registers are laid on the formwork with a predetermined distance from one another before the covering layer is poured with a corresponding reinforcement. For example, in office buildings, since the floor space is only set later, care must be taken that the partitions to be constructed in the intermediate area extend between the area registers of the heat exchangers to avoid erroneous tapping of the pipe coils. For this purpose, measuring points are determined on the formwork for the concrete floor, which are usually marked by nails cut into the slab formwork. The nails projecting with their heads into the poured concrete ceiling remain in the concrete ceiling during demoulding and form marking bodies indicating the course of the distance joints between the individual surface registers of the heat exchangers. Since the nail tips protrude down over the concrete pavement, they are often severed so as not to hinder the application of a plaster layer. But this loses the marking points formed by the nails. If the nail tips are shortened only after the application of a plaster layer, the plaster layer is visibly broken by the nails. In addition, there is the danger that the corrosion of the nails will cause rust spots in the plaster layer.
    The invention is thus based on the object of equipping a cast concrete ceiling with surface registers for room air conditioning with marking bodies in such a way that the marking bodies can be detected in a simple manner without adversely affecting the plaster layer applied to the underside of the floorcovering.
    Starting from a method of the type described above, the invention achieves the stated object in that as a marking body a marking ring made of a ferromagnetic or magnetic material is fastened detachably to the measuring point on the formwork and that for the purpose of locating the mold in the concrete floor remaining, covered by a plaster layer marking ring a freely movable mounted magnetic or ferro-magnetic locating along the plaster layer and is coaxially attracted to the Markie¬ rung ring on the magnetic field of the locating ring and / or the marking ring andie the plaster layer.
    Due to the detachable fastening of the marking rings on the formwork for the concrete floor, the cast concrete floor can be switched off after it has hardened without detaching the marking rings from the concrete floor. As a result of their consolidation on the formwork, marking rings which terminate flush with the concrete surface do not impair the application of a plaster layer on the underside of the concrete surface, so that a continuous plaster layer with a trouble-free visible surface can be ensured. Nevertheless, the marking rings can be easily located through the plaster layer because they are made of a ferromagnetic or magnetic material and can therefore be detected by a ferromagnetic locating ring by means of a magnetic locating ring or a magnetic marking ring. The locating rings and the marking rings are mutually transmitted attracting the magnetic field acting between them, when the locating rings reach the region of the marking rings along the plaster layer. In order to fix the respective measuring point on the plaster layer, the locating ring is therefore to be mounted freely movable in a guide, so that it is attracted to the plaster layer coaxially with the respective marking ring due to the magnetic field line course. Since the marking rings were fastened concentrically to the measuring points on the formwork, the locating ring held magnetically coaxially with the marking rings fixes the respective measuring point with sufficient accuracy, which is marked on the plaster layer by the attracted locating ring or through the locating ring the plaster layer can be drilled.
    The device for locating embedded in a concrete pavement, covered by a plaster layer marking body of a ferromagnetic or magnetic material is characterized by a magnetic or ferromagnetic tracking ring, which around a diametrically opposite circumferential sides of the locating ring deflectable between two legs of a Füh¬ ment deflection means is rotatably mounted. Since the marking rings in the concrete pavement, like the locating rings, are preferably magnetically shaped because of the larger effective forces, the locating ring is to be supported so freely that it is not only attracted to the plaster layer in the area of a magnetic marking ring and not on the surface Plaster layer aligned coaxially to the marking ring, but can also be rotated by a diameter of 180 ° in order to take into account the polarization of the magnetic marker ring and not run Ge¬ that a non-rotatably held locating ring is repelled from the magnetic Marking ring. Such all the requirements in a simple manner corresponding storage of the locating ring is made possible by a traction means which eng¬ on diametrically opposite circumferential sides of the locating ring and allows rotation of the locating ring to the traction means axis.
    The displacement of the locating ring required for aligning the locating ring with respect to a marking ring in the stained ceiling requires a deflection of the traction means held between two limbs of a guide. For this purpose, the elastic traction means between the legs of the guide can be kept taut so that the deflection takes place due to the elastic elongation. However, the resilient clamping forces cause ausrei¬chende magnetic forces to displace the locating ring against the federelasti¬schen bias. The deflection of the traction means without overcoming a spring force can be ensured by a traction means, which has an excess length in relation to the ge¬ leg side leg distance of the guide. The locating ring, which is preferably arranged in the longitudinal center of the traction means, can be freely moved in this case in the context of the excess length of the traction means.
    Reference to the drawing, the inventive method is explained in detail. Show it
    FIG. 1 shows a cast concrete ceiling marked according to the method of the invention in the region of a marking body in a cross section and FIG. FIG. 2 shows a device according to the invention for locating marker bodies which are cast in a concrete ceiling in a partially open side view. FIG.
    As can be seen from FIG. 1, marking bodies 2 for defining measuring points are cast in the cast concrete ceiling 1. These marking bodies 2 according to the exemplary embodiment comprise a magnetic marking ring 3, which is inserted into a frontally open annular chamber 4 at the end of a plastic sleeve 5. This marker body 2 is releasably secured on the formwork thereof before casting the concrete ceiling 1, so that the demoulding of the hardened concrete ceiling 1, the marking body 2 detach from the formwork and remain in the concrete ceiling 1. After applying a plaster layer 6 on the underside of the concrete ceiling 1, the marking body 2 are covered and must be located again if necessary.
    For this purpose, according to FIG. 2, a guide 8 provided, for example, with a handle 7 is provided for a magnetic locating ring 9 which is deflectably held by means of a traction means 10 between two limbs 11 of the guide 8. The traction means 10 engages diametrically opposite circumferential sides on the locating ring 9, so that the locating ring 9, which is arranged in the longitudinal center of the traction means 10, can be rotated about the traction center axis.
    In the case shown, the traction means 10 is designed resiliently in the form of an elastic, so that the traction means 10 can be deflected in all directions when the magnetic locating ring 9 of a corresponding attraction underlies.
    In order to locate a marking body 2 in the concrete ceiling 1 and to fix the measuring point determined by this marking body 2 on the plaster layer 6, the guide 8 is guided via the handle 7 along the plaster layer 6 so that the locating ring 9 enters the magnetic influence area of the magnetic marking ring , as shown in Fig. 1 by the dot-dash line indicated Ortungs¬ device. Due to the effective magnetic forces, the magnetic locating ring 9 is attracted to the plaster layer 6 under a deflection of the expanding traction means 10 and possibly after rotation about the traction means 10 by the marking ring 3 fixed in the staining blanket 1, namely coaxial to the marking ring 3 The rotation of the locating ring 9 always takes place when one of the poles of the same name of the locating ring 9 and the Markierungs¬ ring are facing. The measuring point defined by the marking body 2 can thus be indicated by the locating ring 9 attracted to the plaster layer 6. But it is also possible to drill the plaster layer 6 through the Or¬tungsring 9 therethrough.
    Of course, the invention is not limited to the illustrated embodiment. Thus, the traction means 10 could have an excess length with respect to the mutual spacing of the legs 11 of the guide 8, so that the magnetic locating ring 9 can be displaced freely movably within this excess length. In addition, the locating ring 9 would not have to be made of a magnetic material, but could also consist of a ferromagnetic material if the marking rings 3 form permanent magnets.
