Abstract:
1. A metal system for transferring loads at a crossover point of a joint between at least first, second and third cast-in-place slabs, said system comprising: at least one dowel plate; and at least a first angle joint element attached to the first cast-in-place slab, a second angle joint element attached to the second cast-in-place slab, and a third joint element attached to the third cast-in-place slab, whereby relative movement between at least two of said joint elements occurs during the hardening of the cast-in-place slabs, and wherein the said first, second and third joint elements and at least one dowel plate are adapted so that, after hardening of the cast-in-place slabs and the said relative movement between at least two of said joint elements, the dowel plate has at least a first portion extending within a first piece selected from the group consisting of the first cast-in-place slab after its hardening and a casing attached to the first cast-in place slab after its hardening, a second portion extending within a second piece selected from the group the second cast-in-place slab after its hardening and a casing attached to the second cast-in place slab after its hardening, and a third portion extending within a third piece selected from the group consisting of the third cast-in-place slab after its hardening and a casing attached to the third cast-in place slab after its hardening, and wherein at least a first member selected from the group consisting of one of said joint elements and the casing attached to said one of said joint elements, and a second member selected from the group consisting of another of said joint elements and the casing attached to said another of said joint elements are each provided with means for limiting the relative movements of the dowel plate towards the said at least two joint elements along three orthogonal directions, wherein at least the first angle joint element and the second angle joint element each comprise a profile having a first face portion, a second face portion and an intermediate portion selected from the group consisting of a bent portion and a curved portion extending between the first face portion and the second face portion of the respective angle joint element, wherein at least the first angle joint element and the second angle joint element are each provided with an opening extending in their respective intermediate portion, partly in their respective first face portion and partly in their respective second face portion, wherein the third joint element is provided with an opening, wherein the openings of each of the first angle joint element, the second angle joint element, and the third angle joint element extend substantially in the same plane, and wherein the dowel plate is a plate element extending through the said openings of the first and second angle joint elements and the said opening of the third joint element.
