Abstract
A glued-in-rod wooden structure includes a prepared hole for sealing voids which may be open to the prepared hole. In one example, the prepared hole is filled with an expanding foam which at least partially fills and seals the voids open to the prepared hole. Thereafter, the prepared hole may be enlarged by drilling to its final diameter for receiving the rod. Any voids in the enlarged hole remain sealed by the expanding foam.
Claims20
A glued-in-rod structure configured to receive a rod, comprising:
- a piece of wood, the piece of wood comprising one or more voids;
- and
- a prepared hole, the prepared hole comprising:
- a central axis,
- a foam injected into the prepared hole, the foam at least partially filling at least one void of the one or more voids that is open to the prepared hole, and
- a final hole concentric with the central axis, the final hole having a diameter configured to receive the rod.
A glued-in-rod structure configured to receive a rod, comprising:
- a piece of wood, the piece of wood comprising one or more voids;
- and
- a prepared hole, the prepared hole comprising:
- a central axis,
- a viscous fluid coating the prepared hole and at least partially filling at least one void of the one or more voids that is open to the prepared hole, and
- an adhesive at least partially filling the prepared hole, the viscous fluid preventing the adhesive from leaking into the at least one void.
A method of preparing a hole to receive a rod in a glued-in-rod structure, the glued-in-rod structure comprising one or more voids, the method comprising:
- a) drilling an intermediate hole within the glued-in-rod structure, the intermediate hole open to at least one void of the one or more voids;
- b) injecting a foam into the intermediate hole, the foam at least partially filling the at least one void and hardening;
- and
- c) drilling a final hole, the drilled final hole leaving portions of the foam in the at least one void to seal the at least one void off from the final hole.
