Description

[Detailed Description of the Invention] The present invention aims to utilize natural forest materials that currently have no use and are left in the wild, as well as thinned materials from artificial forests that have almost no use, in developed countries where the energy revolution has advanced. These raw materials are processed into raw materials such as drum material 1, flat log material 2, etc., and these materials are further processed to create log boards with tenons 10 (No. 1a, b).
26
(Fig. 13), log boards with sills (Fig. 14), and other structural materials, as well as construction methods for such structural materials.

◎Materials: Drum wood 1, flat log wood 2 Whether it is natural (grown) wood or artificial (grown) wood, felled wood is called felled wood or raw wood.
Logs are the branches of felled trees or logs cut into appropriate lengths. The upper cutting edge of a log is called the cutting edge, and the lower cutting edge is called the cutting edge (lower cutting edge).

Drum lumber 1. If you cut out the circle of the log parallel to the target from the end and end of the log, and the common center line, the parallel planes will face each other, and the semicircles (round 3) of the lumber will face each other;
The material is drum material (industrially, this material is referred to as drum material) 1 (Figure 1E), which has a drum-shaped cross section.

Opposing flat log material 2, drum material 1; wood circle 3
If one side of the (semicircle) is cut at right angles to the parallel plane,
Parallel planes faced each other, and adjacent semicircles (round or simply round) 3 and planes (flat or simply flat) 4 faced each other; 2 (Fig. 2E).

◎About the thickness of the material and its uses The thickness of the material is the thickness of logs and logs.
Taking an example of an artificial forest, thinning in an artificial forest is
It is necessary to carry out the procedure several times within about 25 years after planting.
For the first session, the diameter at breast height is approximately 12 cm (there are many methods of afforestation techniques, and this example is an average example). When this is made into a log of about 3M, the end (upper wood end)
The diameter is 8-10 cm. From the common center line of the end and base openings, cut out the circle at the end about 1cm parallel to the base mouth on both sides, and the distance between circles 3 and 3 at the end is 8~10cm.
Parallel cut surface is 6-8 cm; Motoguchi = same drum material 1,
becomes.

For the flat log material 2, cut out one side of the circle 3 of the drum material 1 to make the flat material 4, but the distance between the circle 3 and the material 4 (from the material circle 3 to the material material flat 4) is 7 to 9 cm. Become.

A through hole 5' is bored in the material, and the through hole 5 and the plug 9 are integrally fastened into a plate shape, and a log board 10 with a cross and a log board 30 are formed.
(See Figure 1), flat log board 11, flat log board 28
It is used as a structural material such as (see Fig. 2).

The above-mentioned structural materials made from wood from the first thinning are applied to poured concrete, prefabricated concrete plates, interior walls, partition walls, floors, and all walls other than exterior walls in steel framed houses, wooden houses, etc. It can be used for

The wood from the second and subsequent thinnings is thicker and can be used as the structural material of the present invention as an exterior wall material.

◎About the penetration 5 The penetration 5 is the main fastening material that fastens the drum material 1 and the flat log material 2 into a plate-like body (first
~Figure 4).

The materials used in the present invention are quite thick even from the first thinning, and each of the materials made from the second and subsequent thinnings can be used as pillars of houses currently being sold as "ready-built houses."There's no comparison. Furthermore, in nature, trees that are over 25 years old are left without a purpose. They are thick and strong. Constructed from these thick and strong materials; the structural material of the present invention literally looks like a "column plate" and has the ability to do so. In order to connect materials such as pillars into a plate-like body, a strong main material is required.
It is called.

Material of perforation 5: The perforation 5 (see Figures 1 to 4) is
The ``oak tree'' used to form the chassis of the 8th truck, and other strong and durable natural forest materials such as zelkova and loquat were used for this purpose.

◎For the "log board", a through hole 5' that passes orthogonally through the parallel plane of the drum material 1
Drill an appropriate number of holes (Fig. 1D), stack the drum materials with through holes in a row with the holes connected through the perforations 5, and make plug holes 9' that pass orthogonally through the perforations 5 from the opposing circles 3 of the drum materials 1. A log board with holes drilled and plugs 9 (Fig. 1C).

The name ``log board'' comes from the fact that both sides of the ``board'' look like logs lined up side by side.

As a general rule, the punching hole 5 and plug 9 in the log board are made of wood.

The all-wood log board can be processed in all manners such as perforating, cutting, and engraving.

◎For the "flat log board", drill an appropriate number of through holes 5' that perpendicularly pass through the parallel planes of the flat log material 2 (Figure 2D), and connect the flat log materials with the through holes through the through holes 5. Flat log boards (No. 2C
figure).

A "flat log board" is a plate-like object in which the round 3 of the material on one side looks like logs lined up, and the other side is a flat plate where the flat 4 of the flat log material 2 is aligned to form a flat surface. Therefore, it was named ``flat log board'' based on the characteristics of the front and back combination of flat board and round board.

As a general rule, the penetration 5 and plug 9 of the flat log board are made of wood.

The all-wood flat log board can be used in exactly the same way as a regular flat board, and the opposite round board surface can be used for all kinds of work such as engraving, cutting, and perforation.

◎Original form of log board with 〓 and flat log board with 〓 A long drum material 1 is incorporated into the log board 30 (Fig. 1C), a long flat log material 2 is appropriately incorporated into the flat log board 28 (Fig. 2C), and they are integrally constructed. ``Board'' The material that protrudes outside, such as drum wood or flat log wood, is called 〓7, and is also called ``board.''
Protruding through hole 5 to the outside and making it double as 7 is;
It is a log board with a square (Figure 1a) or a flat log board with a square (Figure 2a). What is processed into the frame 8 and attached to the rounded log board 10 in Fig. 1a is the rounded log board 10 with a frame formed (Fig. 1b), which is processed into the rounded flat log board 11 shown in Fig. 2a. The frame 8 is then attached to the flat log board 11 (Fig. 2b) that forms the frame.

Whether or not to attach the frame 8 to the attached log board 10 or the attached flat log board 11 is a matter of personal preference, because the present invention; Log boards, etc. are extremely strong and solid, and the frame 8
The presence or absence of this has nothing to do with strength. However, in the case of the frame 8 (Figs. 1b and 2b), the 〓 that protrudes outside the frame 8 is thinner than the 〓 7 in each of Figs. 1a and 2a, so assembling with huge timbers is restricted. On the other hand, 〓7 in Figures 1a and 2a is thick,
Its thickness of 7 mm makes it possible to frame large pieces of wood, and it also has the advantage of being resistant to breakage accidents.

Log board with tenon [Fig. 1 (see Fig. 3)]: - If the log is cut parallel to the center line of the butt end, drum material 1 will be obtained. A through hole 5' is drilled perpendicularly through the parallel plane of the drum material, and a tenon 6,
A long tenon 7 is constructed, and a frame 8 is provided with a mortise groove 6' and a hole 7'.

The drum material is accumulated by passing the perforation 5 into the through hole 5' of the drum material 1, and both ends of the perforation are made to protrude a certain length to both sides of the accumulated drum material in order to fit into the pillar 13 or the like. A plug hole 9' is made perpendicularly passing through the through hole 5 from the circle 3 of the accumulated drum material, and a plug 9 is driven therein. Tenon of wood end of accumulated drum wood 6,
Fit a frame 8 with a mortise groove 6' and a hole 7' into the long tenon 7 vertically, and drill a plug hole 9' in the tenon from the frame 8 to remove the plug 9.
Or, it is manufactured by driving and fastening wedges 17, etc.; a log board with a tenon.

Flat log board with tenon [Figure 2 (see Figure 3)]: - If the log is cut parallel to the center line of the end, it will become drum wood. One side of the circle of the drum material is further cut out to obtain flat log material 2. A through hole 5' is drilled orthogonally through the parallel plane of the flat log material 2, a tenon 6 or a long tenon 7 is formed at the upper and lower ends, and a mortise groove 6' and a hole 7' are formed in the frame 8. will be established. Penetrating the through hole 5 into the through hole 5' of the flat log material 2, accumulating the flat log material 2,
Both ends of the through-hole are made to protrude a certain length to both sides of the stacked flat logs in order to fit into the pillars 13, etc. A plug hole 9' that passes orthogonally through the perforation 5 from the round 3 or flat 4 of the accumulated flat log material.
and insert plug 9. Frame 8 with a tenon groove 6' and a hole 7' in the end tenon 6 and long tenon 7 of accumulated flat logs
from the top and bottom of the fitting frame 8 to the end of the wood.
A flat log board with a tenon that is manufactured by driving and fastening plugs 9 or wedges, etc.

Figure 3 shows a log board with a tenon on the right side, a flat log board with a tenon on the left side, a pillar 13 on each side, and a base 1 on the bottom.
2 and the upper part are fitted together with a beam 14 (or girder 23, or girder 17) to form a wall of a building, etc.

Wall construction methods vary depending on the growth, species and natural conditions of the material. Japanese cypress and cedar trees grow an average of 7 to 8 millimeters thicker each year. If you use wood that is about 15 years old as the main material for this method, you can use drum material 1 for 10 log boards with tenons, flat log material 2 for 11 flat log boards with tenons, and 1
The outer diameter and strength of a single book correspond to or exceed that of a so-called 3-dimensional pillar. Therefore, the log board with a tenon and the flat log board with a tenon of the present invention used in this construction method can be said to be a [column board]. The positions of the through holes 5 and long tenons protruding from both sides of the adjacent log board with a tenon and the flat log board with a tenon are different.
Drill a through hole 5' in the adjacent log board 10 with a tenon or a flat log board 11 with a tenon and insert the through hole 5, or drill a hole 7' and insert the long tenon 7 into it. By drilling a plug hole 9' that perpendicularly passes through the dowel penetration 5 and the long tenon 7 and driving the plug 9 to connect the two, a wall can be created using only the tenoned log board 10 and the tenoned flat log board 11. (See Figures 4 and 5).

Foundation/floor construction method The external shell foundation made of termite-containing concrete is constructed with a reinforced concrete foundation 15 and a reinforced concrete foundation 16 deep underground, connected below the surface of the sub-floor, and connected under the surface of the sub-floor. The structure shall be designed to prevent infiltration of groundwater, etc. In the area surrounded by the foundation 15 and the foundation mound 16, gravel is filled to a depth of at least one meter from above, slightly higher than the outer porch, and the surface is hardened with concrete for about 30 mounds.
(This is underground 5, where heat circulates with a 6-month difference from above ground.
(This is because gravel is the best conductor of heat and cold that is less than that of rice.) It can be said that the main material composition of all conventional buildings was a single wall, that is, a single shell building. However, in the present invention, in addition to single-wall construction using log boards with tenons 10, flat log boards with tenons 11, etc., which can be called [connected pillar boards] in which each timber is an accumulation of 3-inch square pillars or more, A wide variety of multi-layered wall constructions can be created by combining these materials separately or mutually, or by combining them with H-beam steel and reinforcing fireproof waterproof board 32, etc., which can also be used as the main component of buildings. It is also possible to make the foundation 15 thick according to this layered wall (shell), and the top of the foundation 15, which also serves as a platform for the thick drawer 19, etc., to be made thick (Figures 17 to 20).

If the foundation 15 is configured with a protruding base 15' on the outside according to the thickness of the fireproof waterproof board 32 at a position slightly below the upper part of the ventilation hole 42, the influence of rainwater can be prevented by the fireproof waterproof board 32 (No. 17) ~See Figure 20).

Foundation mound: Traditionally, a floor zuka that supported the thick wire in the middle.
The foundation under the stone was roughly made of shallowly carved stones that were a little wider than the stone and hardened with cement. The shallow and rough foundation suddenly began to sink and the floor curved downward unevenly, bouncing and squeaking in various places.Even the installation of something as heavy as a piano, and the foundation and floor work being redone, were carried out without any suspicion. There is. Unstable floors make it difficult for people to gather together, and the fragile flooring and other construction methods of Japanese-style houses have an immeasurable negative impact on people's minds and bodies. Traditional floorboards, footstones, etc. should be abolished.

The foundation mound 16 has the same height above the ground as the foundation 15, has a wide and thick trapezoid shape as appropriate, and serves as a bridge pier on which to place the thick connecting beams 19 or overlapping beams 20.
6 (see Figures 6-9).

Thickening: - In addition to the essential flaws in foundation work, one of the weaknesses of conventional Japanese architecture is poor thickening.

In the present invention, two or three pieces of wood are connected in a wide plate shape with through holes 5, and connected with plugs 9 or wedges 17 to create a thick draw.

The thick overlapping beam 20 (FIGS. 6 and 7) is at the top.

The strong and wide thick bridge bridged over the wide and perfect foundation 15 and foundation mound 16 distributes the weight over a wide area, so the floor is perfect and will never be distorted.

Up to the rough bed: - Install joists at regular intervals on top of the thick joists and spread the rough bed on top of them. This is the conventional construction method.

In the construction method of the present invention, if the flat log board 28 is fitted on top of the thick hikiki, there is no need for both joist and rough floor construction, and the rough floor becomes much more solid than those (see Figures 8 and 9).

Roof construction method Mine log board: Long and short materials (1 drum material, 2 flat log materials)
A through hole 5' is drilled through the parallel plane at right angles, and the through hole 5' is penetrated to form a triangular, pentagonal, trapezoidal,
Stack them into a plate shape, or stack them like a fence by keeping the intervals between several pieces of stacked wood, and drill plug holes 9' through each hole perpendicularly through the round 3 or flat 4 of the stacked wood and drive the plugs 9. In the form of a plate (Figures 10 to 12) or like a fence (Figure 13)
conclude, constitute.

When the timber is stacked vertically, a tenon 6 and a long tenon 7 are provided at the end of the timber, depending on the position of the combination, and grooves 6' and holes 7' are provided on the underframe 24, depending on the position.
Fit the underframe 24 with a triangular, pentagonal, trapezoidal, etc. log board or fence-like object, drill a plug hole 9', drive the plug 9, and change the external shape to a triangular, pentagonal, trapezoidal, etc., plate-shaped ridge log board 2.
5. Manufacture the fence-like ridge log board 26.

A plate-shaped ridge log board 25, which is constructed by laying the timber horizontally,
In the fence-like ridge log board 26, there is a penetration 5 that protrudes below the timber.
is fitted onto the beam 14 from above.

The ridge log boards 25 and 26 are cut out at appropriate locations, and the ridgepole 21, the purlin 22, etc. are fitted and fastened with the plugs 9.

The plate-shaped ridge log board 25 allows easy step-by-step parallel assembly of the main building 22 and is good for roof stability (Figs. 10 to 12).

Conventionally, in order to support the ridgepole 21, the main building 22, etc., it took a very long time to design, cut, and assemble double beams, sheds, and connecting beams that connect the sheds horizontally. This is because natural wood logs are used for the beams 14 to strengthen the house, and each beam is curved differently, and a double beam is assembled on top of that. Hut Zuka. Joint beam. In particular,
Even a small house requires dozens of huts, and even experts tend to make many mistakes in design and construction.

Mine log board: is a double beam of a traditional Japanese architecture Japanese hut. Hut Zuka. Joint beam. Extremely troublesome calculations for things like hut beams etc. Cut. This eliminates the need for assembly. They are integrated into the present invention; the ridge log board. Included. It has a reinforced structure.

Even when natural wood is used for the beam 14, it is easy to calculate the gap between the ridge log board below the assembly level and the beam 14, and it is easy to compensate for and assemble the two (see Fig. 12).

Mine log boards are used in Western-style wooden Western-style buildings; Directions. This eliminates the need for wooden arrangements such as gassho.

The ladder-shaped ridge log board with stepped sides is ideal for a hipped building, and the main house 22 can be easily assembled on the side - No. 12
figure.

Strapping beam: The beam 27 is located above the beam 14, fixes the section between the beams, and also serves as a stand for assembling log boards (conventional huts), etc. on and in the middle of the beams.

Traditionally, a single thin piece of material was used for the beam.

In the construction method of the present invention, a through hole 5' is bored in the side of a thin piece of wood, two or three pieces of wood are piled up through the hole, and a plug 9 is driven in to fasten it into a plate shape. If the same type of wood has the same area at the end, the log will be stronger. Therefore, instead of thin square timbers, if we use a beam 27 made of two or three drum timbers 1 and flat logs 2 fastened into a plate shape, the weight above will be lightly supported.
Evenly and lightly distributed on the bottom (11th, 6th, 7th
figure).

Parallel purlins: If two purlins 22 are assembled parallel to each other between the ridgepole 21 and the eave girder 23 in a stepwise manner, the roof will be stable and stable (see Figure 11).

Noji flat log board: If the flat log board 28 of the same thickness is attached to the ridgepole 21, the main house 22, and the eave girder 23 with the plugs 9,
There is no need for conventional construction methods such as assembling rafters and laying roof boards, and the construction period is significantly shortened. Moreover, it is strong because it is similar to having rafters installed on the entire surface.

Safe and quick work can be done by fitting the fitting 29 into the flat log board 28 or the like (see Fig. 14).

Tile roofing, etc.: When the flat log board 28 is used as a field and rafter (Fig. 14), a tiled roof can be created by covering it with waterproof paper and attaching tiles, as in the conventional construction method.

A fireproof waterproof board 32 with a large area or a fireproof waterproof board 32 covered with tiles 38 and a flat log board 28 that overlaps them.
Alternatively, each log board 30 is provided with a fitting groove 29', which is overlapped using the overlapping cutout 18 and the cross overlapping cutout 31 (Fig. 15), and the space between the horizontal boards is filled using the conventional method, or A variety of construction methods are also possible, such as polymerizing multiple layers of various thin and long fireproof and waterproof boards to cover the spaces between the boards.

If a pawl 34 is suitably configured on a long tile-like fireproof and waterproof board 33, and a pawl groove 34' into which the pawl 34 fits is formed in the field of the log board 30 and the flat log board 8, a tile-like fireproof and waterproof board is created. The plate 33 can be directly fitted and attached.

A tile stopper 35 having a restraining groove 36 is attached to the field of the flat log board 28 or the log board 30, and the tile-like fireproof and waterproof board 3 is installed.
If a metal restraining rod 37 or the like is inserted or a nail or the like is driven into the restraining hole 37' provided in the uppermost pawl 34 of No. 3, the structure can be stabilized against horizontal and vertical earthquake shaking. If you want to be even more secure, you can drill a common pin groove 39' at both ends of the bottom tile 35 and attach the pin 39, which will prevent it from being thrown up by a major earthquake (No. (See Figure 16). Fig. 16 shows a case where the roof from the ridgepole to the eaves is covered with two long tile-like fireproof and waterproof boards 33, and the upper tile-like fireproof and waterproof board 35 is in contact with the upper plane of the bottom tile-like fireproof and waterproof board 33. They are constructed at the same height.
The tile-like fireproof and waterproof board 33 is strong and firm, and has a structure that prevents dew condensation on the back surface. In this construction method, the full-scale insulation material is attached to the back of the house (the ceiling of the hut).

Ventilation holes 42 are formed in fields, flat log boards 28, etc. as appropriate, and rodent-proof steel 46 is installed (Fig. 14) to communicate the air space 41 under the roof tiles and the outermost wall, the attic space, and the air space under the floor. Each room will also have continuous ventilation. The ventilation holes under the gable of the roof are made large with bird and rat proof steel.

If a tile-like fireproof waterproof board 33 and a fireproof waterproof board 32 with a high-strength steel core are used as the outermost wall, the temperature of the air layer 41 will remain almost constant throughout the year, and the outside air that enters and exits through the ventilation holes in the roof below the gable will be cool in the summer and cool in the winter. Affected by warm underfloor air. The air layer circulates from south to north on the roof and from north to south under the floor (the opposite is true in the southern hemisphere), which acts as a pump and creates a well-ventilated, healthy, and energy-saving house.

Multi-layered shell construction The main structure of the building is made by stacking log boards with tenons 10 and flat log boards with tenons 11, respectively, or by combining them with each other and superimposing them with overlap punches 18, cross overlap punches 31, braces 44, etc. If used as wood, multi-layered buildings can be created.

Polymerization can be performed not only on wood log boards and flat log boards, but also on reinforced concrete and other various fireproof and waterproof boards 32 that have fitting grooves 29', bolt holes 47', etc.

By applying established conventional technology, reinforced concrete plates can be assembled to the base 12, beam 14, girder 17, column 13, etc., or they can be constructed independently as an outer shell.

Figures 17, 18, and 19 show a log board 10 with a tenon,
The main material of the building is a structure in which flat log boards 11 with tenons are laminated individually or mutually using overlapping punching 18, cross overlapping punching 31, braces 44, etc.
Figure 0 shows 14 beams, 23 eaves beams, 17 girders, and 1 base.
2 is polymerized using the upper and lower joining lines.

If the fireproof waterproof board 32 in Figs. 17 to 20 is strong enough to be used as the main material of a building in combination with H-shaped steel, etc., instead of being used as a mere exterior, it is considered the first material.
Figures 7 to 20 are all three-layered buildings.

Highly hygroscopic mortar, earthen walls, etc. will be discarded to prevent termites. Others: For the ``flint beams'' and ``hojos'' that reinforce the corners and top and bottom, log boards of appropriate width, etc., made of strong wood are often used.

The outer edge between the tile and the field shall be sealed with strong bird and rat repellent material.

All ventilation holes 42 are straight. Attach an appropriate rodent-proof steel 46 (examples in Figures 14 and 17 to 20) such as O-shaped.

Unevenness of all main materials. Completely implement anti-termite measures on wood ends, etc.

Modern houses, which have thin parts and do not overcome the shortcomings of Japanese-style architecture, have an extremely short lifespan (25 years, according to the authorities and contractors' response to public complaints on NHK).

Even modern insulation materials are rarely able to compete with the heat-insulating ability of wood, and the longevity of these materials is proven by the surviving ancient buildings.

Features and Effects of the Present Invention 1 Due to the connected column and wall structure, the strength is unparalleled among wooden structures.

2. Due to the connected column and wall structure, the heat retention ability is outstanding.

3 Connecting column wall structure. Rational basic construction method. Multi-layered shell structure/connection, thick drawers, and crossbeams. Flint beam. The structure of the present invention is strong and strong. Buildings have unparalleled earthquake resistance.

A plug hole 9' is made to protrude to both sides of the log material and serve as a hole 7, and a plug hole 9' that passes orthogonally through the perforation 5 is bored from the flat 4 or round 3 of the flat log material 2 stacked in a row. Plug 9 was driven into the plate and the plate was fastened together to form a ``board'', and the part of the flat log that protruded out of the ``board'' was marked 〓7; 3. Drill through-holes 5' that perpendicularly pass through the parallel planes of the material drum material 1 or flat log material 2, and attach the drum materials with long and short and appropriate number of through-holes or flat log materials with through-holes to the ridge (roofing). ), and at that time, the drum material 1 or the flat log material 2 of the raw material is appropriately protruded outside the ridge shape, and the through holes 5' of the arranged drum materials with through holes or flat log materials with through holes are arranged.
The perforations 5 are communicated with the drum material 1 and stacked in a line in a ridge shape, at which time the pierced holes 5 are also made to protrude outside the ridge shape as appropriate, and the drum material 1 is stacked in a row in a ridge shape. Plug holes 9' are drilled through the flat logs 2 or round 3 of the flat logs 2 stacked in rows, and the plugs 9 are driven in and integrally fastened together to form a "renge-shaped board" Through-hole 5 that protrudes outward from the plate
The drum material 1 or the flat log material 2 protruding outside the "mine-shaped board" was made to serve as "7";
