Abstract
Abstract The present sealing device relates to an expansion gap. Such gaps are maintained between adjacent construction members, for example, slabs of concrete forming the roadbed on bridges or the like. A plurality of gap strips are inserted into such gaps and sealing means of elastic material are inserted between adjacent gap strips or between a gap strip and the edges of the construction member which define the gap. In order to improve the positional stability of the gap strips, the invention provides carrier bars which extend directly through apertures in the gap strips and which are supported at their ends in recesses of the edges defining the gap. Bearing means of elastic material are provided between the gap strips and the carrier bars. In one embodiment the bearing means are firmly secured to the carrier bars and to the gap strips. In another embodiment the bearing means comprise the glide pieces permitting a gliding movement between the bearing means proper and the carrier bars.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
178 words
An expansion gap sealing device located between edges of adjacent construction members, said edges defining an expansion gap having a given depth, comprising gap strip means extending substantially across the longitudinal extension of said construction members, sealing means extending alongside said gap strip means in said gap for sealing the gap and providing lateral support for the gap strip means, carRier bars for said gap strip means extending across said gap, apertures in said gap strip means through which said carrier bars extend, and supporting means for said carrier bars located in said edges and at such an elevation relative to the depth of the gap to permit alignment of each carrier bar with the respective apertures in the gap strip means, said supporting means for the carrier bars comprising carrier bar bearing means of elastic material, said gap edges comprising means for properly locating said carrier bar bearing means under a biasing force, said bearing means being firmly attached to said locating means and permitting gliding movement between the carrier bar and the carrier bar bearing means.
Claim 2
Dependent Claim
178 words
An expansion gap sealing device located between edges of adjacent construction members, said edges defining an expansion gap having a given depth, comprising gap strip means extending substantially across the longitudinal extension of said construction members, sealing means extending alongside said gap strip means in said gap for sealing the gap and providing lateral support for the gap strip means, carRier bars for said gap strip means extending across said gap, apertures in said gap strip means through which said carrier bars extend, and supporting means for said carrier bars located in said edges and at such an elevation relative to the depth of the gap to permit alignment of each carrier bar with the respective apertures in the gap strip means, said supporting means for the carrier bars comprising carrier bar bearing means of elastic material, said gap edges comprising means for properly locating said carrier bar bearing means under a biasing force, said bearing means being firmly attached to said locating means and permitting gliding movement between the carrier bar and the carrier bar bearing means.
Claim 3
Dependent Claim
46 words

Claim 8
Dependent Claim
35 words
The expansion gap sealing device according to claim 6, wherein said intermediate means comprise cross pieces and detachable connecting members for releasably connecting any one of said upper and lower rods with the cross pieces.
Claim 9
Dependent Claim
73 words
The expansion gap sealing device according to claim 7, wherein a plurality of said cross pieces is provided for each gap strip means, said cross pieces being spaced from each other to provide said apertures in the gap strip means, said cross pieces having a shape which is symmetrical relative to the longitudinal axis of the gap strip means, said cross pieces having a size corresponding substantially to that of the adjacent aperture.
Claim 10
Dependent Claim
64 words
The expansion gap sealing device according to claim 8, wherein any of said cross pieces comprises two members one above and one below said longitudinal axis of the gap strip means, said apertures having a shape corresponding to that of said cross piece members such that a cross piece member above said longitudinal axis fits into the aperture below the axis and vice versa.
Claim 11
Dependent Claim
62 words
The expansion gap sealing device according to claim 1, comprising elastic glide bearing means (14, 15) located between said gap strip means (11) and said carrier bars (6), means (16) for securing the gap strip means to the glide bearing means, and a gliding fit between the carrier bars (6) and the glide bearing means to permit a relative gliding movement therebetween.
Claim 12
Dependent Claim
43 words
