Abstract

A method of reinforcing a masonry structure is described wherein polyester thread reinforcement strips are manufactured and mounted on the masonry structure to protect it from lateral forces caused by earthquake and other natural occurring phenomena that generally produce bending moments in the masonry structure. The disclosed method can easily and economically be applied to reinforce masonry structures in underprivileged regions.

First claim

The invention claimed is:

1. A method of manufacturing polyester thread reinforcement strips, comprising:
tying a first end of a polyester thread to a first pole of a structure comprising the first pole and a second pole, wherein the first pole and the second pole are parallel and separated by at least 20 cm;
winding a second end of the polyester thread around the second pole of the structure and returning the second end of the polyester thread to the first pole in stretched form to make a wound cycle, wherein the polyester thread is perpendicular to the first and the second poles;
repeating the winding at least 20 times in a back and forth movement to form a polyester thread assembly, wherein each polyester thread is adjacent and parallel to the polyester thread from a previous wound cycle, and wherein no gap is present between the adjacent and parallel polyester threads;
applying an adhesive to the polyester thread assembly;
curing and/or drying the adhesive; and
cutting the polyester thread assembly along the first and the second poles and at least 1 cm from each pole to make the polyester thread reinforcement strip.

2. The method of claim 1 , wherein the cutting forms cut edges on Opposing sides of the polyester thread reinforcement strip, and the method further comprises sealing the cut edges of the polyester thread reinforcement strip by heating, annealing and/or taping.

3. The method of claim 1 , wherein the polyester thread reinforcement strip has an ultimate tensile strength at least four times larger and a maximum tensile load bearing capacity at least three times larger than a substantially similar strip with polypropylene threads instead of polyester threads.
