The invention relates to an arrangement and a method for providing a roof tile with at least one water stop. With the arrangement it becomes possible to press a water stop, comprised of a material differing from that of the roof tile, into a roof tile blank. After the water stop has been pressed in, it is partially disposed with its edge in the material of the roof tile blank in the proximity of the watercourse, of the central brim and of the lateral beading.

摘要:
A method of pre-mounting an anchorage device such as a spike into a concrete object said anchorage device being adapted for fastening the object onto a support surface. The method includes the steps of moulding and vibrating the object (1) in a mould, there being formed a guide recess (4) in the object and the object is being removed from the mould prior to curing the concrete.According to the invention there is formed, during the casting of the concrete object (1), a channel (5) extending from a location centrally of the bottom of the guide recess (4), practically through the object and to a location adjacent that surface of the object turned away from the guide recess. Then the object is removed from the mould and the concrete is cured. On forming the channel, this is given a tapering portion (8, 9) at the end thereof facing away from the guide recess and an approximately uniformly thick portion at the end thereof closest to the guide recess. During removal of the concrete object from the mould and during curing the concrete the channel is left unsupported and after the curing a semi-hard plastic sleeve (11) is inserted into the channel and then the spike is inserted into the sleeve. A certain portion of the sleeve is left to protrude beyond the bottom surface of the guide recess.
