Abstract
A concrete form tie assembly in which the tie rod is formed from a high tensile strength flexible wire member, with the sleeve being formed of a flexible or yieldable material. A short sleeve member is inserted into the spacer sleeve adjacent one end with washer members on opposite ends thereof for retaining on the tie rod member which is provided with spaced protrusions for coaction with the wash members, the tube and washer assembly serving to rigidify the assembly for assisting in insertion and removal of the tie rod and sleeve as a unit. The leading end of the tube and washer assembly may be provided with a conical end to act as a guide. The ends of the tie rod member are enlarged, such as by welding head members thereto, the head members being configured for coaction with conventional hairpin or snap tie wedge members.
Claims11
The combination of a tie assembly and concrete forms, said combination comprising:
- opposed concrete forms spaced a selected distance apart and having aligned pairs of openings therethrough;
- and
- a plurality of tie assemblies extending through a plurality of said aligned pairs of openings and being releasably attached to said forms, each of said tie assemblies including:
- an elongate flexible high tensile strength tie rod member having means disposed at each end thereof for cooperating in releasably mounting the tie rod member in fixed position on the forms;
- rigidifying means affixed adjacent one end of the tie rod member, said rigidifying means including tube means which includes a short tube member positioned and captively retained on said tie rod member;
- an elongate yieldable sleeve positioned on said tie rod member between the ends thereof into interengaging relation with said rigidifying means, said sleeve being of a length greater than the selected distance between the forms, said sleeve with said tie rod member therein being inserted through an aligned pair of openings in the forms with said rigidifying means assisting in the insertion of the tie rod assembly with both ends of the sleeve and a substantial part of said rigidifying means extending beyond the outer surfaces of said forms;
- and
- said tube means being received within said sleeve adjacent one end thereof, said tube means further including metal washer means at each end of said short tube member in frictional engagement with the interior of said sleeve.
The tie assembly for use in concrete pouring in a concrete receiving space between opposed concrete forms spaced a selected distance apart and having aligned pairs of openings therethrough, said tie assembly extending through an aligned pair of openings and being releasably attached to said forms, said tie assembly comprising:
- an elongate flexible high tensile strength wire tie rod member having means disposed at each end thereof for cooperating in releasably mounting the tie rod member in fixed position on the forms;
- rigidifying means affixed adjacent one end of the tie rod member, said rigidifying means including tube means affixed to said tie rod member, said tube means including a short tube member positioned and captively retained on said tie rod member;
- an elongate yieldable sleeve positioned on said tie rod between the ends thereof into interengaging relation with said rigidifying means, said sleeve being of a length greater than the selected distance between the forms for extending therebeyond, said sleeve with said tie rod member therein being inserted through the aligned pair of openings in the forms with said rigidifying means assisting in the insertion of the tie assembly;
- and
- said tube means being received within said sleeve, said tube means further including metal washer means at each end of said short tube member.
A tie assembly for use in concrete pouring in a concrete receiving space between opposed concrete forms spaced a selected distance apart and having aligned pairs of openings therethrough, said tie assembly extending through an aligned pair of openings and being releasably attached to said forms, said tie assembly comprising:
- an elongate flexible high tensile strength tie rod member having means disposed at each end thereof for cooperating in releasably mounting the tie rod member in fixed position on the forms;
- rigidifying means including tube means affixed adjacent one end of the tie rod member, said tube means including a short tube member positioned and captively retained on said tie rod member;
- an elongate yieldable sleeve positioned on said tie rod between the ends thereof into interengaging relation with said rigidifying means, said sleeve being of a length greater than the selected distance between the forms for extending therebeyond, said sleeve with said tie rod member therein being inserted through the aligned pair of openings in the forms with said rigidifying means assisting in the insertion of the tie assembly;
- and
- said tube means being received within said sleeve, with said tube means further including metal washer means at each end of said short tube member.
