Definitions

the invention relates to a holding device as in The preamble of claim 1 is described.
the known holding device must be in the formwork by hand be screwed in. It already shows part 11 elastic material on a steel bolt 1, with which the holding device is fastened in the formwork is enclosing. With the elastic part is achieved that the finished threshold is lifted out of the formwork can, and thereby the holding device from the Screw anchor releases.
the elastic part of the known holding device is made Made of solid material with threads in the screw dowel is turned. It continues pulling out the holding device from the dowel when lifting the concrete threshold there is still considerable resistance to the formwork.
the known holding device is in threshold production cannot be used in the fitted bed because the sleepers are there in the course of the manufacturing process in the formwork (the The fitted bed).
the well-known in the longitudinal axis of the Rigid fixtures would be one Obstruct displacement of the threshold and to Damage to the threshold.
the known holding device is in a compliant cup-shaped part on which the screw dowel can be detached is screwable, and an independent, if necessary shearable fastening means, for example a Rivet, divided for fixation in the formwork.
the pin is useful with two sections educated.
the section inside the screw anchor runs has cylindrical shape that over the dowel part conical up to the threshold contact area Shape up.
the incline of the cone is formed.
the diameter of the cone tapers from the threshold towards the underside of the threshold, when removed from the Installation condition on the upper side of the threshold the diameter of the cone tapers towards this side there.
the holding device 3 On the base plate of a threshold formwork 1 is one Holding device 3 by means of a assigned hole 2 in the formwork 1 and 5 in the bottom 4 connecting means 10 passing through the holding device - appropriately a rivet - attached.
the holding device 3 has a cup shape. Through the cavity 6 of the cup shape a device can be inserted with which Connecting means 10 for fastening the holding device 3 is settable.
the outer surface of the cup is threaded 7 provided, on which a screw plug 19 can be screwed, and has slots 8.
the bottom 4 of the Holding device 3 can be hollow against the base plate the formwork 1 may be shaped so that when it is set Lanyard 10 the edge 9 of the bottom close to the Formwork 1 presses. Anchoring the lanyard 10 can be reinforced by a metal disc 11.
Pins 12, 14 are in the cavity 4 of the holding device 3 can be used with which one the concrete 16 of the threshold in the full height penetrating cavity 17 in the Threshold production in concrete can be kept free.
the one from the bottom opening 20 of the concrete in the threshold 16 concreted screw anchor 19 projecting part 13 or 15 of the pin 12, 14 is conical.
the cone 12 has a conical part 13 with a according to FIG the piercing opening 20 of the screw anchor 19 to the sole surface 18 of the threshold decreasing diameter when he after stripping from the base surface 18 out of the concrete 16 to be knocked out, the pin 14 according to FIG. 4 a conical part 15 with correspondingly increasing Diameter if after stripping from the top the threshold is to be knocked out.
