Abstract
A sealing system designed for use in buildings having log construction. The system makes use of horizontally-oriented channels that are located along the top and bottom face of each log. After the building has been assembled, vertically-oriented bores are drilled into each course of logs. The bore is located so that they interconnect a horizontal channel. Once the bore has been drilled, a liquid sealing material such as caulking is pumped into the bore where it then flows into and fills the horizontal channel.
Claims6
A log building having multiple sealing channels, said log building comprising:
- a plurality of interconnected walls, each of said walls being in the form of a plurality of stacked courses of end to end logs and wherein each course has a top surface;
- a plurality of horizontally-oriented channels located between courses of logs in said walls, wherein each of said channels is formed from a pair of complementary grooves with one of said grooves located in a top surface of a course of logs and the other of said grooves located in a bottom surface of said course of logs, and wherein each of said channels extends substantially the entire length of its associated pair of courses of logs;
- at least one vertically-oriented bore that extends from the top surface of one of said courses to a bottom surface of said course and wherein said bore connects to a channel on a lower surface of said course;
- and
- a quantity of injected sealing material located in said channels and said at least one bore.
A method of building a log wall, said method comprising:
- cutting a groove along substantially the entire length of a top face of a first log;
- cutting a groove along substantially the entire length of a bottom face of a second log;
- placing said second log atop said first log wherein the top face of the first log is in contact with the bottom face of the second log and wherein the groove in the first log is aligned with the groove in said second log and said grooves together form a single channel;
- drilling a vertically-oriented bore through said second log of said wall whereby said bore extends downwardly and through the groove in said second log;
- and
- injecting a liquid sealing material into said bore so that said material flows into the grooves in said first and second logs and thereby forms a seal between said logs.
The method of claim 5 further comprising the step of cutting a groove along the top face of the second log prior to its assembly with said first log.
A log building having multiple sealing channels, said log building comprising:
- a plurality of interconnected walls, each of said walls being in the form of courses of logs, wherein each course has a top surface and a bottom surface;
- a structural member selected from the group consisting of a window or door, inserted into at least one of said walls;
- a groove formed in said structural member proximate said courses of logs;
- a bore formed in a frame member surrounding said structural member;
- and
- a quantity of sealing material located in said groove for sealing said structural member.
