CONSTITUTION:A square pillar cylinder steel 1a and an L-shaped pillar steel are positioned as a support pillar 2 at each corner and a stud part. A steel pillar 4 having an tenon groove is mounted to the side of the support pillar 2 in a manner that a back part 6 opposite to an opening part 5 is brought into contact with the support pillar 2 to form a corner part pillar. Square timbers 8 and 8 are tenoned internally of a space formed with protruding side plates 7 and 7, positioned at the corner part of the corner part pillar, of the steel pillar 4. The end part, to which a joint is formed, of a log or a half log 3 is tenoned with the opening part 5 of the steel pillar 4 to form a wall surface. This method enables absorption of a strain thereafter produced even when green wood is used as the log or the half log 3.

Description

Detailed Description of the Invention (a) Industrial Application Field The present invention is mainly applicable to construction of log houses and other buildings using logs and half-split logs of large-diameter raw trees that have not been dried. The present invention relates to a method for constructing corners using logs and half-logs, which enables high-rise buildings to be formed easily and quickly, and creates grand and beautiful views. (Explanation) Conventional technology Corners in log houses and other constructions using logs have been constructed by notching the ends of each log to create a concave shape, and then fitting the logs into each other at right angles. However,
In order to create the grandeur and beauty that is unique to buildings such as log houses, it is necessary to use large-diameter wooden logs, and since the logs that are incorporated are not square columns but irregular columns, the cutouts between each log It is difficult to form as it requires precision,
This requires advanced technology. Therefore, a patent application has been filed for an invention in which corner parts are constructed by applying joint processing to the ends of logs and half-split logs, and stacking them up while fitting into steel columns with fitting grooves as corner pillars. 63-312444). (c) Problems to be solved by the invention When constructing corner sections of buildings such as log houses using large-diameter logs or half-split logs, the methods conventionally used in countries such as Canada, The logs are notched one by one and then stacked and assembled orthogonally. However, since the logs are cylinders with curved surfaces, curved notches must be processed, which requires advanced technology and makes the work much easier. Difficulties are expected. This will lead to an increase in labor due to longer assembly times, which will lead to higher costs. Now, in order to solve the difficulty of work due to notch processing, etc., a steel column with a fitting groove is provided as a corner column, and the ends of logs and halved logs are processed into the fitting groove and fitted. A patent application has been filed for a method of constructing corner sections to improve work efficiency. However, in order to form corner columns that extend in 4 directions, 3 directions, or 2 directions by combining steel columns with a C-shaped or U-shaped cross section of the fitting groove, depending on the application, logs with joint processing are used. When the ends of logs and half-logs are fitted together perpendicularly to the fitting grooves and stacked, unlike stacking square timbers, the logs and half-logs themselves have curved surfaces, so gaps inevitably occur and corners A portion of each side of the column will be exposed. In other words, the corner columns are made of steel, which is different from wood, and the steel columns are visible on the outside, which makes it a little different for corners of buildings such as log houses where log materials are used and foreign artificial materials are disliked. This will spoil the aesthetic appearance. Therefore, if you want to keep the steel column hidden in appearance, you can fit logs and half logs with a diameter larger than the width of one side of the corner part, but it is necessary to fit them in a perpendicular state, , when the ends of each log and half-log are fitted to the other side adjacent to one side at right angles, the ends other than the fitting part protrude into each other, so physically the ends of each other are It becomes impossible to fit the section to the steel column. In order to prevent the protruding parts from interfering with how they fit together, the protruding parts must be tapered off again. In other words, the processing method that brings the protruding parts of each log and half log into close contact with each other without interfering with the fitting of each other and without any gaps is a process that involves cutting the corresponding logs and half logs in order to fit them together on site. Since each split log would have to be cut to fit each individual log, it would add a lot of work.

By the way, when using large-diameter logs and half-split logs for construction such as log houses, it is necessary to suppress distortion due to shrinkage of the logs and half-logs as much as possible. Therefore, there is the issue of having to dry the logs for a long period of time before the construction stage. In other words, the number of logs and half-split logs used for construction such as log houses is 20cm in diameter for one house based on 66rrl.
Approximately 120 to 150 logs with a length of 4 m are used, and it is naturally expected that the number of logs would be enormous if they were to be mass-produced for several houses. It would take a considerable amount of money to artificially dry a huge number of logs and half-split logs from a raw state, and if we were to preserve them for a long time by natural drying, we would have to secure a vast amount of land. It is certain that this will also have an impact on the rise in land rent costs. The present invention solves more problems than the conventional ones, and makes it possible to construct log houses by using raw wood logs and half-split logs. Using steel columns with grooves and hollow square column steel and L-shaped column steel as support columns, corner columns are shaped to absorb distortion due to shrinkage of logs and half-logs, and In order to unify the interior and exterior of the building with wood and not spoil the aesthetics, square wood was installed between one side of the corner pillar and the other adjacent side to hide the steel pillar, which differs from the wood in appearance. The purpose of this invention is to provide a corner W construction method that allows for the construction of corner sections. (2) Means for solving the problem In order to achieve this object, the present invention has the following configuration.

First, a square column cylindrical steel (1a) and an L-shaped column steel (1b) are placed at each corner and stud part as support columns (2), and a square column cylindrical steel (1a) and an L-shaped column steel (1b) ) The back (6) on the opposite side of the opening (5) of the steel column (4) has a fitting groove with a C-shaped or U-shaped cross section as necessary on each side of the steel column (4).
Hit the target. However, the tip of the support column (2) is higher than the tip of the steel column (4), and the support column (2) is placed in the mortise and tenon (10) of the roof eave and second floor threshold (9). Fit the tip of the In addition, the protruding side plates (7) of the steel columns (4) that are adjacent to each other are placed in contact with the side surfaces of the support columns (2).
The side plates (7) protrude from each other in the space having a right angle between them.
Attach a square piece of wood (8) with the same width as the width. Next, if necessary, the ends of the logs and half-split logs (3) are processed into stepped ears and T-shaped protrusions, so that the cross section is C.
The upper surface of the log and half-log (3) is a steel column (4) so as to be positioned at the top when the wall and corner protrusions are formed by fitting into the U-shaped and U-shaped fitting grooves. Stack them so that they are higher than the tip. Similarly, the door/window frame steel (11) having a fitting groove with a U-shaped cross section is also stacked with logs and half-logs (3) fitted together. Another door/window frame! The mortise and tenon (10) provided at the lower end of the log material and half-split log material (3) corresponding to the upper position of (11) have approximately half to one-fourth of the side width of the corner post. Fit the tips of the door/window frame steel (11) so that there is a gap.

In addition, the eaves and sills (9) at the bottom of the roof, second floor, and the tops of the logs and half-logs (3) to be stacked are only in close contact with each other and are not fixed. Furthermore, the fitted logs and half logs (3) are only fitted and not fixed.

(E) Embodiments Examples of implementing the construction method of the present invention are divided into cases in which a corner protrusion (12) is provided and cases in which a corner protrusion (12) is not provided in order to shape the corner portion.

First, when providing a corner protrusion (12), a square cylinder m (la) is used as the support column (2), and the wall part has a U-shaped cross section on the four sides of the square cylinder steel (1a). A steel column (4) having a C-shaped fitting groove is brought into contact with a steel column (4) having a C-shaped fitting groove in order to fit short logs into the corner protrusion and stack them up. At this stage, the protruding side plates (7) of the steel columns (4) protrude from the sides of the square column steel (la) in directions perpendicular to each other so as to be adjacent to each other. Therefore, between the adjacent protruding side plates (7), a rectangular prism square block (8) having the same width as the protruding side plate (7) is placed.
When the logs and half-split logs (3) with stepped ears or T-shaped protrusions are fitted into the fitting grooves, the steel material Column (4) is visually hidden. Next, regarding the formation of an azekranashi corner that does not have an orthogonal corner protrusion (12), a steel column (4) is brought into contact with a support column (2) made of L-shaped steel (1b), and When the ends of the wall-shaped log material and the half-split log material (3) are fitted into the fitting structure of the steel column (4) to be orthogonal to each other, an L-shaped m (
1b), the protruding side plates (7) of the steel columns (4) protrude in a right angle direction so as to be adjacent to each other. In addition, the support column (2) using the square column WJ steel (1a) and L-shaped steel (1b) is set to a higher position than each steel column (4), and the support column (2) and the steel column (4) are The difference in level is that the tip of the support column (2) is the eave of the roof and the threshold of the second floor (9).
The depth shall be greater than the depth fitted to the mortise and tenon (lO). Furthermore, at the stage where the raw wood logs and half-split logs (3) to be used for the wall are fitted into the fitting groove of the steel column (4) so as to be stacked from bottom to top, the logs and half-split logs Material (3
) is located at the eave of the roof or the threshold of the second floor (9)
It comes into contact with the lower end of. Similarly, for windows and doors, the opening (5) of a steel frame with a U-shaped cross section and the joint-processed ends of logs and half-logs (3) are fitted so that they are stacked from bottom to top. Match. In addition, a mortise groove is provided at the lower end of the log and half-split log (3) located at the top of the steel frame having a U-shaped cross section;
For the mortise (10), the tip, mortise groove, and mortise (10)
) so that there is a gap between them. As the raw wood logs and half-split logs (3) naturally dry over time from the time of completion, they shrink, causing the eaves of the roof and the threshold of the second floor (9) to dry naturally.
) Wall logs and half logs (3)
Due to the weight of the logs and half-split logs (3) themselves, the drying shrinkage falls between the fitting grooves of the steel columns (4) at both ends, so there is a gap between each log and half-split logs (3). There are no gaps between the two, and as they fall downward, they become more firmly established. At that time, the roof eaves and second floor sills (9) that were in contact with the top of the logs and half-split logs (3) also fell down due to their own weight, and the tips of the steel columns (4) This means that there will be no gaps between any parts. (f) Effects of the invention The main problems with the corner construction method using log materials and half log materials in construction such as log houses are as follows.
The pillar itself, which has a fitting groove and is erected as a corner pillar,
It is made of steel rather than wood, which is clearly different from the material of the protruding parts of the wall corners.Furthermore, because it uses logs and half-logs, even if the top and bottom surfaces are processed horizontally, the curved surfaces on the sides remain. However, the curved surface of log wood creates the unique appearance of buildings such as log houses, and for this reason it is not possible to process it to a state similar to that of square wood. Therefore, when stacking logs and half-logs fitted into steel columns one above the other, the surfaces of the steel columns are always exposed to the naked eye. Next, the logs and half-logs used in conventional construction of log houses and the like are sufficiently dried and shrunk before the construction stage is started. Even if steel columns are used, it is certainly possible to improve work efficiency and ease construction, which in turn reduces labor and costs, but it also takes time to dry a large amount of logs and half-logs before construction. Considering the long-term ownership period and securing a vast storage space, this will be a very difficult issue, including land rent.
However, the present invention overcomes all the problems. That is, in the method of constructing a corner section using log materials and half-split log materials according to the present invention, by using a support column for the corner section, the function of the steel column having the fitting groove as a column is strengthened, and the steel column The height of the support pillars can be increased, the eave of the roof and the threshold of the second floor can be fitted to the top of the support pillars, and by connecting and extending the support pillars, they can be used as pillars for the second floor and above, making it suitable for log houses. This also makes it possible to build high-rise buildings such as Now, the problem with the visually exposed steel column surfaces is that by placing square wood in contact with the orthogonal space created between adjacent steel columns, some of the exposed steel column surfaces are hidden, and as a result, the wood This can be solved by creating a natural appearance by eliminating the sense of incongruity with walls, etc.

Next, since we use raw wood logs and half-split logs instead of dried logs and half-split logs, we can store them in large quantities before the construction stage of construction such as log houses. It will be possible to significantly reduce the cost of securing a storage location for long periods of time such as drying, and the associated costs such as land rent. By the way, when raw wood logs and half-split logs are used, fitting grooves should be installed instead of fixing the logs and half-logs to fill gaps that will later occur due to shrinkage due to natural drying. Since the logs and halved logs are piled up while being fitted into the steel columns, the load weight of the logs and halved logs inevitably causes the logs and halved logs to be compressed and lowered due to the considerable downward force of gravity. There are no gaps between them.

If approximately 20 logs and halved logs are stacked, each log and halved log will compress and descend while shrinking, resulting in a drop of several 0 times higher than the initial stacking height at the top. . However, the eaves of the roof and the sill of the second floor are not fixed to the top of the support columns but are fitted,
The weight of the eaves of the roof and the threshold of the second floor itself causes a drop, eliminating the drop. Moreover, since the steel columns with fitting grooves are lower than the support columns, the eaves of the roof and the second floor sills, which have grooves and tenons, smoothly descend while fitting into the support columns and are located at lower levels. It easily touches the top of logs and half-logs on walls, etc. In other words, it anticipates the shrinkage of raw wood and has a wall configuration that can accommodate it from the beginning. Similarly, the fitting grooves of window and door frame steel face the wall logs and half logs, so
The logs and half-logs can be lowered without difficulty.

As described above, the present invention solves the construction of corner columns, which is the biggest problem in the construction stage of log houses, by using steel columns with support columns and fitting grooves. By hiding the steel columns, which are different from wood, while making the work methods easier and shorter, it is possible to maintain the unique appearance of buildings such as log houses.Also, the biggest issue before construction Drying a large amount of logs and half logs, securing long-term storage space, and high costs including land rent can be greatly reduced by making it possible to use raw wood. Furthermore, the present invention provides a method for constructing a corner section using logs and halved logs, which can make the structure more solid by utilizing the shrinkage of raw wood and the weight of the logs and halved logs themselves. It is something.
