Abstract
A method of forming a joint between a metal structural tubular member and a metal sleeve. The method comprises placing the sleeve around a part of the tubular member so that there is a space between the sleeve and the adjacent part of the tubular member, closing the ends of at least a part of the space between the tubular member and the sleeve, injecting a hardenable composition into the space between the closed ends and maintaining the pressure until set. The method can be used for joining together structural tubular members or for repairing a damaged structural member.
Claims6
A method of repairing a damaged structural tubular member including the steps of providing a sleeve which is divided longitudinally and has cylindrical end portions and an enlarged central portion, placing the said divided sleeve around said structural tubular member with said enlarged portion around said damaged part, so that there is a space between each cylindrical end portion of the sleeve and the adjacent part of the tubular member, closing the ends of at least the said spaces between the cylindrical end portions and the tubular member, injecting a hardenable composition through the wall of the sleeve into the space between the closed ends, and maintaining the composition under pressure until set.
