  19. (c) The method according to claim 18, wherein the sealant spreader is rotated while the sealant spreader device is lifted from the hole, thereby covering the wall of the hole with a thin layer of sealant.
  20. The method according to claim 18, further comprising providing an air passage through the interior of the sealant spreader device to allow for the equalization of pressure above and below the sealant spreader device when the sealant spreader device is lifted out of and/or inserted into the hole.

Description

(Priority) This application claims priority to U.S. Patent Application No. 17/961,018, filed on October 6, 2022, entitled "SEALANT SPREADER DEVICE FOR USE IN PREPARING HOLES FOR GLUED-IN-ROD STRUCTURES," which is incorporated herein by reference in its entirety. The glue-in-rod (GIR) system is known as a system in which a rod is glued into a hole drilled in wood. This wood may be solid lumber or made of artificial wood products such as structural composite materials (SCL) or cross-laminated timber (CLT). In GIR, when adhesive is injected into the drilled hole to embed the rod, the adhesive leaks into the voids in the wood surrounding the drilled hole. This leakage results in insufficient adhesive at the interface between the wood and the rod, preventing a secure bond.

Figure 17 shows a sealant spreader, according to an embodiment of this technology, being inserted into and removed from a hole.Figure 17 shows a sealant spreader, according to an embodiment of this technology, being inserted into and removed from a hole.Figure 17 shows a sealant spreader, according to an embodiment of this technology, being inserted into and removed from a hole. This technology, broadly speaking, relates to a sealant spreader device for filling voids around drilled holes in glued-in-rod (GIR) structures with sealant. In wood structures, such as natural wood and artificial wood products, voids may exist within the wood. In natural wood, voids may be present within the wood grain. In artificial wood products, such as cross-laminated timber, voids may be present in the wood grain and/or in the areas where wood pieces are glued together. According to this technology, before gluing the rod into the drilled hole, the sealant may be applied to the hole using the sealant spreader device of this technology and pressed into the voids around the inner surface of the hole. The sealant spreader device of this technology may be attached to the rod or may include the rod. The sealant spreader device may be attached to one end of the rod, and the other end of the rod may be fitted into a drill to rotate the rod and the sealant spreader device. During the process, liquid sealant is applied to the base (bottom) of the drilled hole. The amount of sealant depends on the depth and diameter of the drilled hole. A sealant spreader device (usually abbreviated as SSD in this specification) is then inserted through the sealant down to the base of the drilled hole. The SSD is then withdrawn while rotating. The sealant spreader device includes wing-shaped sections with a contour that pushes the sealant radially outward toward the hole walls, forcing the sealant into the voids around the inner surface of the drilled hole, leaving a thin layer of sealant on the inner surface of the drilled hole. It is understood th
