Sealing strip for expansion gaps, especially in road pavements

Claim 2

A sealing strip for an expansion gap with a pair of superposed strip gripping means located in said gap, facing each other and defining a vertical gripping space, the strip comprising sidewalls, at least one horizontal wall, and, for connecting said horizontal wall to each sidewall, a holding member extending substantially in the direction of said horizontal wall and a supporting member extending at an angle relative to said horizontal and sidewalls to form with a portion of the sidewall a connection triangle, the space confined by said walls being substantially free of other holding and supporting elements, and said sidewalls having a height exceeding said gripping space.

Claim 3

The sealing strip according to claim 1, wherein the connection triangle portion of the strip sidewall has an indentation pointing toward the adjacent supporting member.

Claim 4

The sealing strip according to claim 1, wherein the connection triangle portion of the strip sidewall has along its length a section opposite said supporting member, which section has a reduced cross-sectional area as compared to the sidewall cross-sectional area outside said connection triangle.

Claim 5

The sealing strip according to claim 1, for an expansion gap with strip gripping claws extending into the gap and then downwardly to form recesses in the gap structure, upper and lower ridges of the strip sidewalls fitting elastically into the recesses.

Claim 6

A sealing strip for an expansion gap, especially in road pavements with strip gripping means located in said gap and facing each other, comprising strip sidewalls having upper and lower ridges adapted to fit into said gripping means, at least one horizontal wall, and means for connecting said horizontal wall to said strip sidewalls, said connecting means consisting of a holding member and a supporting member for each connection, said holding member extending substantially in the direction of said horizontal wall and said supporting member extending at an angle relative to said horizontal wall and relative to said strip sidewalls, said holding member and said supporting member forming with a portion of the adjacent strip sidewall a connection triangle, wherein the sum of the area moments of inertia of the holding and supporting members is smaller than the area moment of inertia of said horizontal wall, while the space confined by said walls is free of other holding and supporting elements.

Claim 7

A sealing strip for an expansion gap, especially in road pavements with strip gripping means located in said gap and facing each other, comprising strip sidewalls having upper and lower ridges adapted to fit into said gripping means, at least one horizontal wall, and means for connecting said horizontal wall to said strip sidewalls, said connecting means consisting of a holding member and a supporting member for each connection, said holding member extending substantially in the direction of said horizontal wall and said supporting member extending at an angle relative to said horizontal wall and relative to said strip sidewalls, said holding member and said supporting member forming with a portion of the adjacent strip sidewall a connection triangle, wherein the sum of the area moments of inertia of the holding and supporting members is smaller than the area moment of inertia of said horizontal wall, while the space confined by said walls is free of other holding and supporting elements.

Claim 8

The sealing strip according to claim 5, including a further horizontal wall and additional connecting means for connecting the further horizontal wall to said sidewalls, the horizontal wall forming top and bottom walls of the sealing strip.

Claim 9

The sealing strip according to claim 5, wherein the sum of the thickness of the holding and supporting members is larger than the thickness of the horizontal wall.

Claim 10

The sealing strip according to claim 5, wherein said gripping means comprise claws, and wherein the sum of the thicknesses of the holding and supporting members and of the sidewall portion within said connection triangle is smaller than the width of the claws.

Claim 11

The sealing strip according to claim 5, wherein the cross-sectional area of said holding member is larger than the cross-sectional area of said supporting member.
