DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention is, while presenting the appearance of a log house, on the load-bearing structure is loading the logs in the log house
Regardless of the normal "log set method" to build up on top, about the building and its construction methods by framing structure that supports the whole building I'm in the post <br/>.

[0002]

2. Description of the Related Art In a log house, the skin of a log material and the grain of a solid square material have a natural appearance and a simple appearance, and a wide log is excellent in a heat insulating effect.
It has the advantage of being warm in winter and cool in summer, and is popular as a villa or lodge-like building. And the construction method,
Log material or wide square material, as it is or as a half-split type,
It is common to build up by horizontally or vertically stacking by fitting unevenness and the like, and engaging the intersection with a notch or the like which is tightly connected in an intermittence type. However, this method has the following drawbacks, and is currently rarely used for ordinary houses.

The reasons are as follows: a) Since natural logs are used, notch dimensional standards are not standardized, and forces are deviated in the axial direction between the lower stack and the upper stack to easily cause eccentricity mechanically and structural strength. It is unsuitable for building two-story or three-story buildings because the calculation is not established. B) The structural strength is unstable, so the area of each room must be limited to a small one. -It is difficult to take up a large indoor space such as mums. C) Logs are likely to shrink significantly over time, and doors and windows will be out of order after a few months, making opening and closing windows difficult. D) Because natural logs are used for the outer wall, the structure is considered to be a structure that may spread the fire as it is, and it was difficult to construct the city planning area if no measures were taken against the spread of the fire. .

[0004]

SUMMARY OF THE INVENTION Based on the above-mentioned circumstances, the present invention is based on: a) a more stable building structure which does not use the log braiding method, and the appearance of a log house, and b) measures against burning. An object of the present invention is to obtain a building and a building method without the risk of spreading fire.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, the embodiment will now be described with reference to FIG. 1. As shown in FIG. It is formed wide to mount it.

Reference numeral 2 denotes a support, a base 2a below, and a girder 2b above.
The base 2a is connected to the foundation 1 with anchor bolts, and the mortise is carved on the base 2a. In the case of a two-story building, the beam 2b is fixed with a tenon or a slat bolt, and the beam 2b is fixed with a tenon on the support 2 or the girder b. As shown in FIG. 3, the support 2 has a curved outer wall such as a window frame or a door frame.
The support of the opening frame 3, regardless of the outer wall of the log material 4a, between the struts 2,2 (or between studs 2c) or fitted directly or attached to a support which is extended from the standoff 2, either Also, it is desirable that the support is supported by the column 2 without being framed from the cutout of the log material as in the conventional log house.
By taking the form of extending from the latter column 2, it is possible to use a bay window type (not shown).

Next, in FIG. 2 in which a part of the notch portion is enlarged, reference numeral 4 denotes a log house-like outer wall portion in which log materials 4a are stacked, and log materials 4a are round logs, D logs, square logs. And a rectangular log, etc., and the assembling method thereof is not limited to any of a method of forming a concave and convex on the mutual contact surface and fitting the same, and a method of cutting a tenon vertically and inserting a reinforcing plate. In addition, assembling of the intersection can be performed by using a normal log assembling method such as a round notch, a saddle notch, and a wedge notch. Then, the soil coating wall 5 is formed on the inner side in close contact with the log material 4a of the outer wall portion 4. The method of forming the soil coating wall 5 is such that the soil is usually pressed with a trowel and applied by a trowel like a soil coating craftsman. A wall may be used, but, for example, the following construction method enables simple work without the involvement of a craftsman. That is, as shown in FIG. 4, first, a base plate 7 as a plate-like body is attached between the columns 2 and 2 by nailing or the like.
The outer wall portion 4 is formed by stacking the log materials 4a at intervals of about mm. An air gap 8 is provided between the base plate 7 and the outer wall 4, and a sheet 9 for covering the gap between the log materials 4a is hung down to give a fluidity in the air gap 8. Is poured using a discharger or the like. At this time, it is desirable to use a moisture-permeable plate material such as a perforated plate for the base plate 7 in order to speed up drying of the filled earthen wall 5. In addition, the soil coating wall 5
It is desirable to interpose a wooden dance 6 such as a round bamboo that is woven in a lattice shape with a wooden dance rope. Further, the formation of the soil coating wall 5 can be performed by the following method. First, a square formwork of about 90 mm is prepared, a base plate 7 is laid at the lowermost stage, a wooden dance 6 is inserted therein, a coating soil is filled therein and molded under a slightly pressurized state. Make it. Then, this is brought to the construction site, the ground plate 7 is nailed to the pillar 2 including the stud, and the square molded products are sequentially joined to form a series of wall materials (not shown). At this time, bringing the earthen wall 5 into close contact with the log material 4a means that the earth wall portion 5 fills the gap between the log materials 4a and that the heat shielding effect of the earth wall is obtained. .

In order to increase the close contact between the soil coating wall 5 and the log material 4a, as shown in FIG. 5, a bolt 10a is passed through the column 2, and a female screw plate 10b fixed to the column 2 in the middle is provided. And a raising device 10 in which a contact plate 10c that contacts the base plate 7 is applied to the tip of the bolt 10a. When the head of the bolt 10a is rotated, the raising device 10 advances in a spiral motion through the female screw 10b, and the abutment plate 10c presses the base plate 7, and as a result, the soil coating wall 5 It can be brought into close contact with the material 4a side.

The support 2 and the outer wall 4 are preferably formed by connecting the connecting material 11 extending from the support 2 because the support is strong against the axial force but very weak against the horizontal force. It extends to the outer wall part 4 and aims at mutual connection. For example, as shown in FIG.
Then, a part of a is drilled and a nut is fastened 11b. Alternatively, as shown in FIG. 7, a U-shaped metal piece is sandwiched between the column 2 and the log material 4a as a connecting material, and the two are nailed and connected (see FIG. 7).
This connection is made by the log material 4a against the lateral load of the column 2.
Reinforces it to fulfill the role of bracing.

Next, the operation of the present embodiment will be described. In the building of the present invention, a load such as a roof or a beam is not received by a log material forming an outer wall, and a support pillar 2 provided on a foundation has a roof or a beam. A repulsive force is generated inside against the compressive action received from the load of the beam, and a resistive force is exerted in the axial direction to obtain a stable supporting force. Conventionally, the log assembly method has the disadvantage that the notch size is not unified due to natural logs, the axial force is shifted between lower stacking and upper stacking, eccentricity is likely to occur, and structural strength calculation is not established. To eliminate. Therefore, even in a two-story or three-story building, the structure can be calculated based on the columns,
Even under such load, a solid building can be obtained. Also, when designing a large living room or dining room, a large indoor space can be ensured because it does not rely on wall materials.

Further, by obtaining the support of the window frame or the door frame 3 from the support, no matter how much the log material shrinks, the door or the window does not get out of order. The log material has a large change with time, and its shrinkage is as large as 40%, which hinders the opening and closing of windows and closing of doors, but this works smoothly.

The connecting member 11 connects the support 2 and a part of the outer wall 4 to each other.
When joined together, the log material 4a supports the load two-dimensionally, so it exerts a strong resistance against the force from the horizontal direction, reinforces the structure of the column weak against this horizontal force, and supplements or eliminates braces And

Next, the clay wall 5 has two functions, one of which functions to cut off the supply of oxygen. That is, the outer wall portion 4
Since the non-combustible earth coating wall 5 is closely interposed between the base plate 7 and the base plate 7, even if a fire spreads, the inflow of air is cut off and the supply of oxygen is stopped. Furthermore, even if it receives the heat at the time of a fire spread, the earth coating wall 5 as a noncombustible material blocks the heat, and does not transmit the heat applied from the outside to the surroundings and the inside.
Therefore, supply of oxygen and an increase in combustion heat as combustion conditions are suppressed, and the entire structure exhibits a strong flameproof action against fire spread.

In the construction method, when a plate-like body is attached to the column 2 and the log material 4a is stacked on the foundation, a gap 8 is formed between the outer wall portion 4 and the base plate 7. If it is filled with clay or liquid soil, the outer wall 4 and the base plate 7
, The log material 4a and the topcoat wall 5 naturally come into close contact with each other. In addition, the work is simple without the need for ironing or the like. At this time, if the sheet 9 is hung on the back side of the log material 4a on the outer wall portion 4 side and is filled with clay-like or liquid coating soil, the flexible sheet 9 is applied along the back side of the log material, Even if there is a gap between the log materials 4, the coating soil does not leak out, and a beautiful finish is obtained. Also,
Separate sheets are provided on the outer wall side and the base plate 7 side in the gap 8 respectively.
, And fill the sheets 9 with liquid soil.
If it is filled, the flexible sheet 9 will follow the log material and the base plate 7
If the log material 4a and the base plate 7
The soil is not leaked even when
It is a bad finish. Furthermore, another method of construction, clay coating
It surrounds the base and comprising a plate-like body wall formwork, integrally molded earth coating material is pressed after demolding in a slightly pressurized state by filling the coated soil into the mold and
According towards <br/> method for forming a stack concurrently with overcoating wall logs material used, it is possible to produce the integrally molded earth coating of this factory. During the production, pressurization is possible, so that the wooden dance 6 and the coated soil are compressed and entangled firmly, and the solid soil coated wall 5 is pressed.
It can be. After that, it is transported to the construction site, where the log material is stacked at the construction site and the clay wall is formed at the same time.
Form, since it can be a series of wall material, the work is simple productivity higher due. In addition, log house-like building
Regarding the construction method at the construction site,
It is not limited only to

[0017]

According to the present invention based on the above-described structure, a two-story or three-story high-structure can be provided because a frame structure can be formed by columns without relying on mechanical support for an uncertain combination of log materials. And a large room space can be secured. In addition, the outer wall opening such as
If the frame is taken from a structure such as a pillar, there is no deviation over time,
Doors can be closed and windows can be opened and closed smoothly. Further, since the outer wall portion has a disaster prevention function, there is no possibility that a fire spread from a neighborhood even if it is built in a city planning area or the like. In addition, as the method of construction, it is possible to adopt a method in which the log material and the earthen wall are easily brought into close contact with each other, and a method of efficiently producing a strong earthen wall. Therefore, the present invention is an advantageous invention that can provide a log building with an external appearance, a structurally strong structure with a frame structure, and a building with excellent disaster prevention.
