CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is a continuation-in-part of copending application Ser. No. 09/878,900, filed Jun. 11, 2001, which is herewith incorporated by reference in its entirety; the application also claims the priority, under 35 U.S.C. .sctn. 119, of German patent applications 100 28 202.4, of Jun. 9, 2000; 200 15 845.7 of Jun. 9, 2000; and 100 50 113.3 of Oct. 9, 2000; the foreign applications are herewith incorporated by reference in their entirety. BACKGROUND OF THE INVENTION FIELD OF THE INVENTION [0002] The invention relates to a gap seal on a structure, in particular a building structure, using a water-tight cover disposed over a joint of structure, a corner of a structure, or on an offset part of a structure. [0003] Building-structure seals against moisture from the ground and against water which does or does not exert hydrostatic pressure in accordance with DIN 18 195 are known, for example, as "unlined tanking" made of water-impermeable concrete or as "lined tanking" made of seals which retain pressurized or built-up water. Such building-structure seals are made of bitumen sheeting and plastic sheet material with or without a fabric insert or a thick asphalt coating with or without a fabric insert. Some of the sealing measures mentioned above in the above DIN document are regarded as not corresponding to the recognized rules of technology, with the result that, despite such building-structure seals being installed in accordance with DIN, structural damage may be produced by penetrating moisture. A relatively high risk of structural damage is brought about here by the known susceptibility to deficiencies and/or damage of drainage systems. [0004] U.S. Pat. No. 4,654,250 to Black describes a gap seal. There, a water-tight tape is placed over a soft, malleable sealant, and the tape seals against a first and a second structure (e.g., a bathtub and a wall). Only a limited amount of movement between the two structures is allowed, in the context of Black's gap seal and proper sealing is no longer assured when the two structures shift relative to one another. SUMMARY OF THE INVENTION [0005] It is an object of the invention to provide a gap seal on building structures which overcomes the hereinafore-mentioned disadvantages of the heretofore-known devices and methods for sealing a gap on building structures. It is an object of the invention to make available a permanently functional building-structure seal, in particular in conjunction with a thick asphalt coating, which ensures a reliable seal even against water which exerts hydrostatic pressure, in particular with cohesive soil without drainage, and for structural joints where the members are subject to considerable amounts of relative movement. [0006] The invention is straightforward, cost-effective and makes available a permanently functional building-structure seal. [0007] The above objects are achieved according to the invention by way of a water tight sealing profile with a relatively soft central part with two sides and relatively hard side wings at the two sides. [0008] With the above and other objects in view there is also provided, in accordance with the invention, a gap seal for a building structure, comprising: [0009] a water-tight profile strip having a central part and side wings integrally formed laterally on said central part; [0010] said side wings being formed of a relatively hard, relatively rigid material; [0011] said central part being formed of a relatively soft, elastic material and having a material reserve allowing said side wings to move laterally apart from one another while remaining integrally connected with said central part. [0012] A sealant may be placed in the gap area, but it is not necessary anymore in light of the novel configuration of the gap seal profile. In that case, the sealant forms a continuous, cured sealing layer between the contact surfaces and a building structure, once the profile has been subjected to pressure. The sealant can be a resin which cures to a tough state or a resin which cures to an elastic state. [0013] Another feature of the instant invention is that the central part is at least partially elastic. [0014] Another feature of the instant invention is that the profile have profiled contact surfaces on the side wings. [0015] Another feature of the instant invention is that the side wings have different wing widths. [0016] Another feature of the instant invention is that the cover layer is disposed over a joint of a building, in or in front of a corner of a building or on an offset part of a building. [0017] This solution makes available a permanently functional building-structure seal, in particular in conjunction with a thick asphalt coating and/or in conjunction with two building structures that a subject to considerable shifting, which ensures a reliable seal even against water which exerts hydrostatic pressure, in particular with cohesive soil without drainage. Provided at the same time is a particularly straightforward-to-install, and thus absolutely water-tight, solution for corner seals of upright structural parts and concave moldings on foundations, attics, balconies, showers, window sills, terrace terminations and also for roof surfaces, cap flashing pieces, strip fittings for bridges, parking decks and, in addition, also for settlement joints. [0018] Since the cover layer includes a profile which is, or can be, adapted to an installation situation over a joint or on an inner or outer corner and has a central part and side wings disposed on both sides of the central part, and at least the side wings have, over their length, contact surfaces for coating with a sealant, it is possible, by virtue of the selection of the sealant, for example resin or adhesive, and the method of applying the same, be this by brush application, spraying or filling, to achieve an optimized gap seal to solve virtually any conceivable problem. Also, any gaps which may be present beneath the profile also being filled by the sealant. [0019] In the case in which sealant is provided, the sealant forms a continuous, cured sealing layer, once the profile has been subjected to pressure, between the common contact surfaces of the gap seal and a building structure, said sealing layer having a minimum layer thickness which prevents moisture from penetrating between the profile and a wall, ceiling, or a floor. [0020] Depending on the use purpose, the profile may optionally be in web-like strips or be wound up to form a roll or in the form of a section. Such a section of a profile, for sealing round or polygonal parts of a building or buildings, may advantageously be formed as a segment in a manner corresponding to said parts of the building, for example it is possible for a plurality of curved segments to be joined together to form a ring and thus to seal the foot of a circular-cylindrical part of the building. Such a segment may also be a corner element for an inner or outer corner and in addition, for angle adaptation to a corner which is to be sealed, may have partially overlapping side wings, with the result that corners which deviate from an ideal dimension can also be sealed reliably.
