DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a log house or the like using a log material and a half log material, in which a support is easily and quickly installed, and thereafter, the log and the half log are easily and quickly installed. The present invention relates to a steel strut using a log material and a half log material so that a wall surface can be formed by being fitted to a steel pillar, and a construction method.

[0002]

2. Description of the Related Art A corner portion in a log house or the like using a log material has been constructed by performing a notch process to form a concave portion at an end portion of each log material, and fitting them to each other at right angles. However, in order to create a magnificent view peculiar to architecture such as log houses, large-diameter wooden logs must be used, and since the logs to be incorporated are irregular columns, the cutouts between the logs are accurately formed. It is very difficult and requires advanced technology.

[0003] Therefore, the ends of the log material and the half log material are subjected to connection processing, and are stacked while fitting the end portions of the short log material and the half log material to a steel material pillar having a fitting groove as a corner part pillar. To construct a corner part by using this method (Patent No. 1608)
No. 648) and a patent application for completely hiding the column made of steel from the outside (Japanese Unexamined Patent Publication No. 1-16045).
0) has been submitted.

[0004]

When constructing a corner portion in a log house or the like using a log, a short log, and a half log in a large-diameter tree, each log has been in operation for many years. In the case of the notch processing, that is, the notch processing method, a high level of technology is required, and the difficulty of the operation is expected.

Therefore, in order to solve the difficulty of the work due to the notch processing, a method has been invented in which a steel pillar is installed to form a corner pillar or the like, and a log is fitted to the steel pillar.
That is, in the patent (Japanese Patent No. 1608648), the corner pillars and the studs are formed by combining C-shaped and U-shaped steel pillars, and furthermore, the pillars made of steel are completely hidden in appearance. A patent application (Japanese Patent Application Laid-Open No. 1-160450) which improved the above has been also submitted.

By the way, the steel columns having a C-shaped or U-shaped cross section used in Japanese Patent No. 1608648 and Japanese Patent Laid-Open Publication No. 1-160450 are combined to form corner pillars and studs. First, the work of forming the support itself is required.

However, in a building such as a log house, since a wall or the like is formed by using a log material and a half log material, the weight load on each pillar is much higher than that of a normal building. In addition, steel columns having a C-shaped or U-shaped cross section must be combined in accordance with the usage of each support, which makes designing a building structure difficult.

[0008] Also, in the construction stage, a pillar must be formed and installed by combining steel pillars having a C-shaped or U-shaped cross section in accordance with applications such as corner pillars and studs. In order to fit the jointed ends of the log and the half log in conformity with the U-shaped cross-section opening, two types of processing of the ends of the log and the half log must also be formed. Must.

That is, it is necessary to combine steel columns having a C-shaped or U-shaped cross section at the stage of forming the columns.
In addition, it is necessary to form the ends of the log material and the half log material according to the C-shape and the U-shape cross-section by using a mold adapted to each support, and the length of working time becomes an issue. .

Further, the cross section of the formed column itself is C-shaped,
Due to the combination of U-shaped steel columns, the strength against torsional load is weak, and the work of fitting logs and half logs has to be fairly accurate and careful, and the work time is long. The strength of the support and the strut are also issues.

According to the present invention, in order to solve the above-mentioned problems, a log and a half log are used as needed to construct a log house or the like. It is a type of log and half log that can simplify the formation and installation of the strut, make the connection of the log and half-logged log ends uniform, and further increase the strength of the strut. It is an object of the present invention to provide a steel strut using a material and a construction method.

[0012]

In order to achieve this object, the present invention has the following arrangement. As pillars for buildings such as log houses, the short-distance tips (3) of the tips projecting in eight directions with a well-shaped cross section are connected to each other at four locations as a set using flat steel (4). The well-shaped steel material (7) having a structure that is sealed and the distal ends (5) are maintained as openings (6) is used as a pillar.

The pillar of the present invention is a pillar which is common to all corner pillars, studs and the like. After the pillar is installed on the base, a log (1) having a convex end (8) or a stepped pillar is used. Each end of the half log material (2) having the ear end (9) is fitted into the opening (6) according to the use form, and is stacked from below to form a wall surface. .

At this time, the diameter of the log material (1) or the half-split log material (2) in which the cut surfaces are combined so as to make the log look external is larger than the width of the well-shaped steel material (7). In this case, the well-shaped steel material (7) has a structure that cannot be seen.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described. A well-shaped steel material (7) having a hollow inside is formed by welding or the like, and a short-distance tip (3) is extended from eight directions. 4) The flat steel (4) is connected and sealed at four locations, but the distal ends (5) are kept as they are as the openings (6) to complete the support as a use form.

First, at the stage where the support of the present invention is appropriately fixed to the base, a convex end (8) in which the end of the log material (1) is formed into a convex shape with respect to the opening (6), Half log material (2)
It is necessary to position the stepped end portion (9) so that the stepped ear end portion (9) can be fitted.

Next, the log material (1) and the half log material (2) are piled up from below to form a wall surface. It is not necessary to fit the opening (6) from the upper part of the shaped steel material (7), and the fitting can be performed from the horizontal direction.

Further, a log material (1) and a half log material (2)
Is larger than the width of the well-shaped steel (7), so that the well-shaped steel (7) itself is hidden in the log (1) and the half-log (2) simply by being fitted. It can not be seen from above, and it can be installed by a common construction method for all pillars, whether they are corner pillars or studs.

[0019]

As one of the major problems in the construction of a log house or the like, there is a difficulty in processing and assembling when constructing a corner portion and a wall surface by notching a large log material and assembling it into a well shape. For this reason, inventions have been made in which a steel material pillar is installed as a corner pillar, and a log material and a half log material forming a wall surface are fitted to a corner projecting portion extending outward from all sides, thereby simplifying work difficulty. However, it must be constructed by combining steel pillars having a C-shaped or U-shaped cross section according to the use of each pillar, and the work of forming the pillar itself is added. In addition, even after the pillars are installed, the ends of the log and half-split log must be cut into two types in accordance with the C-shaped and U-shaped steel columns, respectively. It will increase.

Also, a column fitted with a steel column having a C-shaped or U-shaped cross section is vulnerable to the load due to twisting, and the wall surface is twisted at the stage of fitting the ends of the log and the half log. It can be a difficult task.

However, the present invention overcomes both problems. First, since a common well-shaped steel material is used not only for the corner pillars and the studs but also for all the pillars, it is not necessary to form the pillars in a suitable place, that is, to form the pillars by combining several kinds of steel materials. Since it is only necessary to form a column having a common standard, it is naturally possible to simplify the work involved and shorten the work time.

Next, the opening of the well-shaped steel material is also of a common type so that the ends of the log material and the half log material can be fitted together, and the ends of the log material and the half log material must be fitted together. Only one kind of connection processing of the convex end portion and the stepped ear end portion suffices, which also simplifies the reduction of work, thereby shortening the work time and eventually saving costs.

Further, in order to strengthen the strength of the torsion load applied to the column by forming the wall surface using the log member and the half log member, eight ends of the column member formed by the well-shaped steel material are used. Of the parts, the flat steel is provided in four places as a set of the short-distance tip parts. Moreover, this results in considerable strength and durability against the weight load applied to the entire column.

The diameter of the log material and the half log material is set to be larger than the width of the well-shaped steel material. Will be completely invisible, and the architectural appearance of log houses with log specifications will be maintained.

As described above, the present invention simplifies the work and shortens the work time when forming a wall through a pillar when constructing a log house or the like by using a log and a half-split log, It is intended to provide a steel strut using a log material and a half log material, which can enhance the strength and durability of the building, and create an aesthetic appearance as a building such as a log house.
