Abstract

A sectional edge strip for casting integrally with a concrete shape having a groove adapted to hold the edge of elastic jointing strip and grooves extending along the entire length of the sectional edge strip whereby fixing screws can be fitted at freely selected points fastening the strip to the mold for the concrete.

Claims

1. A sectional edge strip for casting integrally with a concrete shape comprising;

a jointing strip groove adapted to take the edge of an elastic jointing strip, said edge strip having at least one side which is adjacent the mold during the production process of the concrete shape with two screw receiving grooves having their axes at right angles extending along its entire length into which fixing screws can be screwed at right angles to each other at freely selectable points, so that the two sides of the sectional edge strip which are to adjoin the mold can be, for at least the duration of the concrete casting operation, secured to two parts of the mold disposed at right angles to each other.

2. A sectional edge strip as defined in claim 1 wherein the grooves for the fixing screws are so disposed as to be covered by a jointing strip upon applying same.

3. A sectional edge strip as defined in claim 1 wherein at least the grooves for taking the fixing screws have grooved sidewalls, the grooved sidewalls corresponding with the profile of the nut thread of said screws.

4. A sectional edge strip as defined in claim 1 having a groove directed with its open side to the interior of the concrete shape to be produced, said groove extending along the entire length of the sectional strip and adapted to take anchor bolts screwable thereinto at freely selected points.

5. A sectional edge strip as defined in claim 1 wherein the centerline of the groove intended for taking the edge section of an elastic jointing strip is at substantially an angle of 45°

with the two limiting faces of the concrete shape to be produced.

6. A sectional edge strip for casting integrally with a concrete shape at the juncture of two angular faces comprising;

a jointing strip groove adapted to take the edge of an elastic jointing strip, two screw receiving grooves into which fixing screws can be fitted at freely selected points extending along the entire length of one side of said sectional edge strip which is adjacent the mold during the production process of the concrete shape so that both sides of the sectional edge strip which are to adjoin the mold can be, for at least the duration of the casting of the concrete shape, secured by said screws to two parts of the mold disposed at the desired angle to each other to form said angular faces.

7. A sectional edge strip as defined in claim 6 wherein the grooves for the fixing screws are so disposed as to be covered by a jointing strip upon applying same.

8. A sectional edge strip as defined in claim 6 wherein at least the groove intended for taking the fixing screws has grooved sidewalls, the grooved sidewalls corresponding with the profile of the nut thread of said screws.

9. A sectional edge strip as defined in claim 6 having a groove directed with its open side to the interior of the concrete shape to be produced, said groove extending along the entire length of the sectional strip and adapted to take anchor bolts screwable thereinto at freely selected points.

10. A sectional edge strip as defined in claim 6 wherein the centerline of the groove intended for taking the edge section of an elastic jointing strip is at substantially an angle of 45°

with the two limiting faces of the concrete shape to be produced.
