Abstract

The invention relates to the articulated imbrication of concrete slabs i(in situ) wherein joints are formed by laying i(in situ), along joint lines, a simple armored mesh device with a cut and fold pattern which has been already prepared in the workshop. Advantage is taken from the retraction phenomenon in order to achieve an alternative indentation along the joints of adjacent slabs of continuous cast concrete, susceptible of forming satisfactorily a knee—or gimbal-joint connection between the joints. The process is complemented with a concrete separator element which facilitates the formation of the crack and prevents water from reaching the platform, and which can be fixed to said device. The invention applies to concrete surface roads, highways and harbour zones of goods warehouses and enables to design and make road surfaces without bases and subbases.

Claims

1. An on-site joint forming process in concrete paving comprising:

a) providing a plurality of wires, each of said wires comprising a first elongate portion that is disposable along a surface to be paved and a second portion that is disposed at an angle relative to said first portion;

b) placing the plurality of wires on the surface to be paved at a site at which a joint is to be formed with a first set of the plurality of wires in a first zone of the site and a second set of the plurality of wires in an adjoining zone of the site and with the first set of the wires disposed along the surface in a first direction and the second set of the wires disposed along the surface in an opposite direction, said plurality of wires being constructed and disposed with respect to one another such that, upon pouring of concrete over the plurality of wires and shrinking of the poured concrete, a joint is formed between adjoining concrete slabs with the slabs having a periodic arrangement of protrusions and recessions that prevents vertical movement between the slabs; and

(c) pouring concrete over the plurality of wires and allowing the poured concrete to shrink with formation of the joint and adjoining concrete slabs.

2. The process according to claim 1, comprising providing the plurality of wires with the angle between the first and second portions of each of said plurality of wires being an acute angle.

3. An on-site joint forming process in concrete paving comprising:

a) providing a plurality of wires, each of said wires comprising a first elongate portion that is disposable along a surface to be paved and a second portion that is disposed at an acute angle relative to said first portion;

b) placing the plurality of wires on the surface to be paved at a site at which a joint is to be formed with a first set of the plurality of wires in a first zone of the site and a second set of the plurality of wires in an adjoining zone of the site and with the first set of the wires disposed along the surface in a first direction and the second set of the wires disposed along the surface in an opposite direction, said plurality of wires being constructed and disposed with respect to one another such that, upon pouring of concrete over the plurality of wires and shrinking of the poured concrete, a joint is formed between adjoining concrete slabs with the slabs having an arrangement of protrusions and recessions that prevents vertical movement between the slabs; and

c) pouring concrete over the plurality of wires and allowing the poured concrete to shrink with formation of the joint and adjoining concrete slabs.

4. The process according to claim 3, comprising placing the plurality of wires on the surface to be paved such that, upon pouring of concrete over the plurality of wires and shrinking of the poured concrete, the arrangement of the protrusions and recessions of the concrete slabs is periodic.

5. An on-site joint forming process in concrete paving comprising:

a) providing joint-forming elements (2) having a plurality of inclined meshed parts (13, 14), that are inclined in a common angle in relation to a plane perpendicular to a surface to be paved but in opposite direction in adjoining meshed parts (13, 14);

b) placing said joint-forming elements at a site at which a joint is to be formed such that, upon pouring of concrete over the joint-forming elements and shrinking of the poured concrete, a joint is formed between adjoining slabs (8,9) with the slabs having an arrangement of protrusions (16) and recessions (15) that prevents vertical movement between the slabs (8,9); and

c) pouring concrete over the joint-forming elements so as to leave a weakened zone (40) in an upper part at the site at which a joint is to be formed for cooperating to form the joint and allowing the poured concrete to shrink with formation of the joint and adjoining concrete slabs.

6. The process according to claim 5, comprising placing the joint-forming elements such that, upon pouring of concrete over the joint-forming elements and shrinking of the poured concrete, the adjoining concrete slabs have an arrangement of protrusions and recessions that is periodic.
