Description

[Detailed explanation of the invention] [Purpose of the invention] Industrial application field The invention facilitates the assembly of logs to be stacked in a collapsed manner, reducing the amount of work at the site, and also easily corrects the misalignment between the logs to be stacked. The present invention relates to a load-bearing wall structure in a log cabin designed to prevent damage.

Conventional Technology Conventionally, when assembling a log cabin, in order to prevent the upper and lower parts of the logs to be stacked upside down, the upper part of each log was formed into a substantially triangular cross section, and the lower part was removed. It is formed to match the shape of the upper part of the lower log, and the logs are piled up to form a load-bearing wall, and the intersection of the upper and lower logs is formed with unevenness to form the corner of the log cabin. At least the logs were loaded.

However, when assembling such logs on-site, each log must be processed one by one according to the variations in shape and size of each log, and processing of the logs requires considerable labor. I had to spend it.

Furthermore, the incorporated logs had the disadvantage that accurate dimensions could not be set due to the difficulty of processing the logs, resulting in gaps between the logs.

Problems to be Solved by the Invention The present invention forms the top, bottom, and indoor sides of the logs that are to be piled up and down to form the load-bearing walls of a log cabin flush with each other, and forms grooves in the top and bottom parts of the logs. A load-bearing wall is formed by fitting a belt-shaped log into a groove and stacking logs, which simplifies the assembly of a log cabin, eliminates gaps and misalignment between the upper and lower logs that are stacked upside down, and prevents such logs from being stacked. By forming a joint on one interior side of the log cabin and a joint on the other side of the butt end, it is easy to assemble the intersection that forms the corner of the log cabin, reducing the labor spent on manufacturing the log cabin on site. The purpose of the present invention is to provide a load-bearing wall structure for a log cabin that is designed to be compressed.

[Structure of the idea]

Means for Solving the Problems In view of the above, the present invention provides a load-bearing wall for a log cabin in which logs are piled upright, in which the upper and lower parts of the logs to be piled upright are formed horizontally to form the top and bottom parts. A load-bearing wall for a log cabin, in which logs are stacked by forming concave grooves in the longitudinal direction of the top and bottom parts, and by fitting band-shaped bulges into the grooves, or by stacking logs in a lying position. In this method, the upper and lower parts of the logs to be piled up are formed horizontally to form a top surface and a bottom surface, grooves are formed in the longitudinal direction of the top surface and bottom surface, and the inner wall side is formed flush with each other. A joint is formed at an appropriate position on the inner wall surface, and a joint is formed on the butt end surface of the other log to fit into the joint, and the joint is fitted into the recess. The present invention attempts to solve the above-mentioned drawbacks by providing a load-bearing wall structure for log cabins in which logs are stacked by fitting belt-shaped logs into grooves.

Function The present invention forms the upper and lower parts of the logs to be stacked upside down so that they are flush, grooves are formed in the longitudinal direction of the top and bottom parts, and a band-shaped bar is fitted into the grooves to hold the logs. By stacking the logs tightly, a load-bearing wall is formed and the upper and lower logs are prevented from shifting.

Also, the indoor side of the log is formed flush with each other, a joint is formed at an appropriate position on the inner wall surface, a joint is formed on the butt end surface of the other log, and the joint of each log is fitted into the joint. By stacking the logs on top of each other, they form load-bearing walls that form the corners of the log cabin.
