Abstract

In a method for connecting a reinforcement or facing of hydraulic-setting material of cement mortar mixture or concrete mixture on a structural component, a multi-layer reinforcement mat is attached to a structural component. A smoothing cement of hydraulic-setting material is filled into outer fabric layers of the reinforcement mat. The smoothing cement is allowed to set to form a substitute formwork. Into the space between the substitute formwork and the structural component a flowable cement mortar mixture or concrete mixture is filled in.

Claims

1. A method for connecting a reinforcement or facing of hydraulic-setting material of cement mortar mixture or concrete mixture on a structural component, the method comprising the steps of:

attaching a multi-layer reinforcement mat on a structural component;

introducing a smoothing cement of hydraulic-setting material into outer fabric layers of the reinforcement mat;

allowing the smoothing cement to set to form a substitute formwork;

filling into a space between the substitute formwork and the structural component a flowable cement mortar mixture or concrete mixture.

2. The method according to claim 1, wherein the reinforcement mat is resting flat immediately on the structural component.

3. The method according to claim 1, wherein the reinforcement mat is connected to the structural component at a spacing from a surface of the structural component.

4. The method according to claim 1, wherein the reinforcement mat is comprised of at least three fabric layers comprised of wire with wire diameter in a range of 0.5 to 3.5 mm, wherein the fabric layers have a mesh size of 2 mm to 60 mm, respectively, and the fabric layers differ from one another with respect to wire diameter and mesh size.

5. The method according to claim 1, wherein the smoothing cement is infiltrated into the outer fabric layers through a hose by applying pressure.

6. The method according to claim 1, wherein the smoothing cement contains fibers, preferably plastic fibers.

7. The method according to claim 1, wherein, in the step of attaching, the reinforcement mat is attached by mechanical anchoring elements on the structural component.

8. The method according to claim 1, wherein the smoothing cement has a stiff consistency and a minimal flow table value.

9. The method according to claim 8, wherein the flow table value of the smoothing cement is in the range of approximately 40% to 60% of a flow table value of the cement mortar mixture or concrete mixture that is filled into the space between the substitute formwork and the structural component.

10. A structural component product comprising:

a structural component;

a reinforcement or facing attached to the structural component and comprised of a multi-layer reinforcement mat and a hydraulic-set material of cement mortar mixture or concrete mixture;

wherein the reinforcement or facing comprises an outer skin positioned at a spacing from the structural component and formed from a hydraulic-set smoothing cement filled into outer fabric layers of the reinforcement mat;

wherein the reinforcement or facing further comprises an intermediate layer of set cement mortar mixture or concrete mixture that fills a space between the outer skin and the structural component;

wherein the smoothing cement of the outer skin is made from a cement mortar mixture or concrete mixture with stiff consistency and minimal flow table value, that is in the range of approximately 40% to 60% of a flow table value of the cement mortar mixture or concrete mixture that has been filled into the space between the outer skin and the structural component to form the intermediate layer.

11. The structural component product according to claim 10, wherein the reinforcement mat is attached flat immediately on the structural component.

12. The structural component product according to claim 10, wherein the reinforcement mat is connected to the structural component at a spacing from a surface of the structural component.

13. The structural component product according to claim 10, wherein the reinforcement mat is comprised of at least three fabric layers comprised of wire with wire diameter in a range of 0.5 to 3.5 mm, wherein the fabric layers have a mesh size of 2 mm to 60 mm, respectively.

14. The structural component product according to claim 13, wherein the fabric layers differ from one another with respect to wire diameter and mesh size.

15. The structural component product according to claim 10, wherein the outer skin contains fibers, preferably plastic fibers.

16. The structural component product according to claim 10, comprising mechanical anchoring elements that secure the reinforcement mat on the structural component.

17. The structural component product according to claim 10, wherein the reinforcement mat is comprised of outer fabric layers integrated into the outer skin and inner fabric layers integrated into the intermediate layer, wherein the outer fabric layers are comprised of wire having a wire diameter that is smaller than a wire diameter of the wire of the inner fabric layers and wherein a mesh size of the outer fabric layers is smaller than a mesh size of the inner fabric layers.

18. The structural component product according to claim 10, wherein the reinforcement mat is comprised of at least 5 fabric layers.

20. The structural component product according to claim 10, wherein the smoothing cement is a smoothing mortar.

19. The structural component product, wherein the reinforcement mat is comprised of up to 20 fabric layers.
