Abstract
A joint-sealing strip is made of soft foam material, with an impregnation leading to delayed recovery. In order to obtain a simple structure combined with an advantageous design especially with respect to technical handling, the impregnation varies over the width of the joint-sealing strip, namely in a marginal longitudinal area. A strengthened impregnation is made preferably extending over the total thickness in the marginal longitudinal area, in such a manner that upon release of the recovery, a profile rising toward a longitudinal center line of the joint-sealing strip is obtained.
Claims18
A joint-sealing strip comprising
- a soft, integral foam material, having an impregnation leading to delayed recovery, said sealing strip being a one-piece strip consisting of open-celled foam;
- said joint-sealing strip having a width, and having a longitudinal centerline with a marginal longitudinal area on each side of said centerline;
- said marginal longitudinal area having a total thickness, and having a width;
- said impregnation differing with a different concentration across the width of the joint-sealing strip, and a strengthened impregnation located in at least one marginal longitudinal area and extending up to the total thickness in said marginal longitudinal area,
- whereby the joint sealing strip shortly upon release from compression during the recovery and prior to the complete recovery is capable of having a rising profile toward the longitudinal center line of the joint-sealing strip.
Joint-sealing strip comprising
- a soft, integral foam material, having an impregnation leading to delayed recovery, said sealing strip being a one piece strip consisting of open-celled foam;
- and
- said joint-sealing strip having a longitudinal centerline with a marginal longitudinal area on each side of said centerline;
- said joint-sealing strip having a width;
- and the impregnation is only in the marginal longitudinal areas and with a different concentration across the width of the strip;
- whereby the joint sealing strip shortly upon release from compression during the recovery and prior to the complete recovery is capable of having a rising profile toward a longitudinal center line of the joint-sealing strip.
