It is a longitudinal cross-sectional view.

First, referring to FIG. 1, the structure of the unit member A constituting each of the structural structures described below will be described.

The unit member A is divided into two halves by dividing a log having a predetermined length from substantially the center to form a half-split body. Is formed at a position where the distance of the predetermined distance is a predetermined value, and a flat surface bonding surface 2 serving as a rear surface bonding portion is further formed at a predetermined position of the dividing surface 1 in a direction perpendicular to the dividing surface. Is formed.

That is, the distance between the division surface 1 and the back surface 2 is the thickness of the unit member A, and the distance between the side surface 3 is the width of the unit member A. In particular, the width dimension of the unit member A is formed to be twice the thickness dimension. The width is set to 1/6 of the module size of the building.

Therefore, by appropriately setting the length of the unit member A, it is possible to correspond to the height dimension of the structure to be constituted, and by forming the module member having a preset module dimension, It is possible to configure a panel or a pillar as a unit constituting a building surface.

Also, the back surface 2
The surface 4 between the side surface 3 and the side surface 3 is used with the outer surface of the log as it is or with the skin peeled off, and with the curved surface remaining. However, when the thickness of the log is different from the end of the log, the cross section of the unit member A may enter the cross section of the base. In this case, in order to form a space 6 described later, it is necessary to drop a corner portion on the side of the original opening.

As described above, since the unit member A is formed by dividing a log in half, it can be manufactured from a relatively thin log such as a thinned wood. In addition, since the surface 3 is used as it is, the loss of wood removal can be reduced, the degree of processing can be extremely reduced, and the manufacturing cost can be reduced.

Next, a description will be given of a structural structure according to a first embodiment constituted by using the unit member A with reference to FIGS. The surface according to the present embodiment is configured as panels B and columns C having dimensions corresponding to the modules of the building, and is manufactured in advance at the factory stage, and is carried into a building site and assembled. This is to make it possible to configure a target surface.

In FIG. 2, as shown in FIG. 2A, the panel B is arranged in two rows in the thickness direction with the unit members A back to back, and a predetermined number in the width direction (in this embodiment, 5
This is configured by aligning and bonding the respective joining surfaces 2 and 3. Therefore, panel B has a width dimension that is equal to the module dimension, and a thickness dimension that is 1/6 of the module dimension.

At both ends in the width direction of the panel B, an end member 5 obtained by further dividing the unit member A into two parts is arranged in order to make the end surface a smooth surface without grooves. Are adhered to the unit member A with the arc-shaped surface 4 inside. The elongated space 6 along the longitudinal direction of the unit member A of the panel B is formed by the surface 4 of the unit member A and the surface 4 of the end member 5 adhered in a predetermined number in the width direction and arranged in two rows. Is formed.

The plurality of unit members A constituting the panel B are
The back joining surface 2 and the side joining surface 3 are bonded to the opposing joining surfaces 2 and 3 of another unit member A or the end member 5 disposed adjacent to each other. For this reason, the joining surfaces 2 and 3 are formed with a sufficiently large joining area so that sufficient strength can be guaranteed.

In the panel B configured as described above, the unit members A are adhered to each other, have a width corresponding to the module size, and have a thickness of 1/6 of the module size. For this reason, by producing a plurality of panels B in a factory in advance, it is possible to configure a surface such as a wall surface, a floor surface, or a roof surface in substantially the same manner as a wooden panel or a concrete panel.

As shown in FIG. 2B, the column C is constituted only by the end member 5. That is, the end members 5 obtained by further dividing the unit member A in half are bonded to each other with the arc-shaped surface 4 inside, so that the size of one side is 1/6 of the module size and the space 6 is formed inside. The formed column C is formed.

The column C constructed as described above is factory-produced in advance and can be used together with the panel B when constructing a building surface.

Next, the construction D according to the second embodiment will be described with reference to FIGS. In the drawings, the same portions and portions having the same functions as those of the above-described embodiment are denoted by the same reference numerals, and description thereof will be omitted.

The construction surface D according to the present embodiment is configured by connecting unit members E arranged in a back-to-back manner in two rows and arranged in a predetermined number in the width direction by a connecting member 10.
The unit member E can be connected without using an adhesive on the structural surface D, and can be easily disassembled by removing the connecting member 10.

The unit member E is formed on the basis of the above-described unit member A, and has a back surface 2 in the unit member A.
A groove 11 serving as a joint portion is formed in FIG. Accordingly, the thickness and width of the unit member E have the same values as those of the unit member A. Further, the division surface 1 in the unit member E
On the back surface side, a plane constituting the back surface joining surface 2 is formed, and on both side surfaces, side surface joining surfaces 3 are formed.

A plurality of grooves 11 are formed in a direction perpendicular to the longitudinal direction of the unit member E and at predetermined positions along the longitudinal direction at predetermined intervals with a predetermined interval. Therefore, when the plurality of unit members E are aligned in parallel with their longitudinal ends aligned, the groove 11 is arranged in a straight line across the aligned plurality of unit members E.

The groove 11 has a predetermined depth and is formed so that the size of the groove bottom portion is larger than the size of the opening portion, and a pair of grooves are provided on both sides in the width direction (the longitudinal direction of the unit member E). The surface 11a is formed.

The connecting member 10 fits into a groove 11 formed in the unit member E, and connects a plurality of unit members E arranged in a predetermined arrangement state to each other. For this reason, the connecting member 10 has a sectional shape corresponding to the groove 11 formed in the unit member E. That is, when the connecting members 10 are aligned in two rows with the unit members E facing each other, the connecting members 10 are shaped such that the grooves 11 formed in the respective unit members E face each other (see the side view in FIG. 7). ) Is formed with a sectional shape obtained by dividing a material having substantially the same shape as that of the above) into two with a sliding gradient.

In this embodiment, the length of the connecting member 10 is about three times the width of the unit member E, and the width is substantially equal to or slightly smaller than twice the depth of the groove 11. Degree value,
When the two connecting members 10 are overlapped, the height thereof has a value substantially equal to the vertical dimension of the unit member E of the groove 11. A V-shaped groove surface 10a having the same shape as the abutting surfaces 11a of the pair of grooves 11 is formed on the upper portion,
A sliding slope surface 10b is formed in the lower part. Further, a through hole 10c is formed along the space 6 at a predetermined position corresponding to the space 6 on the V-shaped groove surface 10a.

Accordingly, the high end and the low end of the two connecting members 10 are combined into a pair, and the sliding surfaces 10b are brought into contact with each other so that the inclined surfaces 10b are opposed to each other and have a groove surface 10a.
11a, the groove surface 10a is aligned with the groove 11 of the unit members E arranged back to back in two rows and aligned in a predetermined number in the width direction. Contact evenly with 11a.

As shown in FIG. 8, when a force in the longitudinal direction is applied to the connecting member 10, the sliding members slide on each other along the inclined surface 10b. Is applied, the connecting member 10 and the unit member E are pressed against each other, and are connected according to the friction coefficient and the acting force. The force acting on the surface 10a in the thickness direction of the unit member E acts so as to draw the unit members E aligned back to back, and the component force along the longitudinal direction of the unit member E. Acts to firmly connect these unit members to each other.

Therefore, as shown in FIG.
A plurality of unit members E are aligned in accordance with the dimensions of the desired construction surface such as a floor surface or a roof surface, and the connecting members 10 are fitted into the facing grooves 10 and driven into each other, thereby forming the desired construction surface D. It is possible to configure. At this time, a plurality of grooves 11 formed at predetermined intervals in the longitudinal direction of the unit member E are provided.
By displacing the engagement position of the connecting member 10 to be fitted in the width direction of the construction surface D, regardless of the length of the connecting member 10, the adjacent unit members E can connect the plurality of connecting members 10 to each other. Connected via

Therefore, even when an external force in the width direction is applied to the unit member E, the construction surface D is not decomposed, and the wide construction surface D is maintained in a firmly connected state. It is possible to configure. In particular, a force acting in an in-plane direction typified by an axial shear force can be opposed by the connecting member 10, and a force acting in an out-of-plane direction typified by an out-of-plane bending force Can be opposed by the groove surface 10a of the connecting member 10 with the groove surface 11a of the groove 11.

In the case where the above-mentioned construction surface D is used as an outer wall surface, for example, as shown in FIG. By providing the airtightness and watertightness, it is possible to improve the airtightness and the watertightness, and it is possible to prevent the aligned unit members E from shifting in the out-of-plane direction.

When connecting a plurality of aligned unit members E, it is not necessarily limited to using the connecting member 10 described above. That is, the connecting member may be any member that can connect the unit members E to each other across the aligned unit members E. Even if the connecting member and the unit member E are joined by an adhesive, good.

As such a connecting member, for example, FIG.
As shown in (a) and (b), there is a middle crosspiece 13 having a rectangular cross section. In this case, a square groove 14 serving as a joint is formed on the back surface of the unit member E. The vertical dimension of the square groove 14 has a value corresponding to the thickness of the middle rail 13 so that the middle rail 13 can be fitted and an adhesive layer can be formed, and the depth is sufficient. In order to realize a joint area, it has a value of at least １ ／ or more of the width dimension of the middle crosspiece 13.

In the case where a plurality of unit members E are connected to each other using the middle crosspiece 13 to form a construction surface, the unit members E are back-to-back in two rows with the square groove 14 and the middle crosspiece 13 coated with an adhesive. And a plurality of them are aligned in the width direction, and the center rail 13 is fitted to the opposed square groove 14, whereby the center rail 13 and the unit member E are bonded and connected. Further, the unit members constituting one surface of the construction surface are aligned in a line, and the square grooves 14
After the adhesive is applied to the square groove 14 and the middle crosspiece 13 is fitted into the square groove 14, the unit member constituting the other surface of the structure in which the adhesive is applied to the square groove 14 in advance on the middle groove 13 is formed. It is also possible to connect by fitting E.

In the case of constructing the structural surface, when the plurality of unit members E are not connected only by the middle rail 13 but both the middle rail 13 and the connecting member 10 are used, FIG. As shown, a groove 15 which also serves as a joint groove and a square groove serving as a joining portion is formed on the back surface of the unit member E in a portion where the both are joined,
The connecting member 16 has a cross section having the same shape as the groove 15.

As described above, by using the groove 15 and the connecting member 16 which also serve as the groove and the middle crosspiece, it is possible to form a structural surface by connecting the unit members E by bonding at the portion where the middle crosspiece is arranged. In addition, at the positions where the grooves are arranged, the unit members E can be connected to each other by pressing the grooves 15 and the connecting members 16 to form a structural surface.

Next, a description will be given of a structure for attaching a surface to a surface attachment portion formed in a building with reference to FIGS.

In the figure, the unit constituting the target surface uses the panel B according to the first embodiment described above.

The base of the building is provided with a base 20 and a beam 21 which are fixed to a foundation or other portion serving as a structural surface mounting portion. At the predetermined positions of these bases 20 and beams 21, reinforcing steel
Holes 20a and 21a for inserting the holes 22 are formed.
Counterbore holes 20b and 21b are formed continuously from a and 21a.

Accordingly, the panel B is disposed between the base 20 and the beam 21, the reinforcing bar 22 is inserted into the space 6 formed inside the panel B, and the reinforcing bar 22 is connected to the hole 20 a of the base 20 and the beam 21. Hole 21
a, and further, by fastening a nut 23b via a washer 23a, the panel B is sandwiched between the base 20 and the beam 21 so that the panel B can be attached to the surface mounting portion. It is possible.

Then, by arranging a predetermined number of panels B and fastening the arranged panels B to the base 20 and the beams 21 by the reinforcing bars 22, it is possible to form a desired construction surface.

In the above-structured surface structure, the upper and lower fore-edge portions of the panel B formed by aligning the plurality of unit members A and corresponding to the side surface joining surfaces 3 include: It is preferable that a hiring girdle 23 is provided between the base 20 and the beam 21, and the hiring girder 23 improves the airtightness and watertightness of the structural surface.

In the above-described panel B, the unit member A has a dimension equal to the height of the target surface, but the length of the unit member A does not necessarily have to match the height of the target surface. As shown in FIG. 12, a predetermined number of relatively short unit members A are arranged in the width direction (for example, the same number as that of the panel B), and the block-shaped unit members F formed by adhering to each other are stacked in the height direction. These unit bodies F can be connected to each other by the reinforcing bar 22 in the same manner as in the case of the panel B to form a target structure. Even in this case, it is preferable to arrange the hiring tongue 23 between the blocks to improve airtightness and watertightness.

When manufacturing the unit F, the unit member A
Can be configured by matching the length of the target unit body F with the length of the target unit body F, aligning the unit members A back to back in two rows, aligning a predetermined number in the width direction, and bonding them together. It is. Alternatively, it is also possible to manufacture a structure similar to that of the panel B in advance, and cut this structure at a length set for the unit body F.

[0054]

As described above in detail, in the surface construction according to the present invention, since the unit members constituting the surface are formed by dividing the log in half, there is little loss in logging and the log is effectively used. You can do it. Also, a simple processing can be performed on the half-split material to form a unit member, and the processing can be performed by a general-purpose woodworking machine without using a special machine. For this reason, cost can be reduced.

Further, in a structure formed by fitting and connecting a connecting member to a joint formed on the back surface of the unit member,
Various structural surfaces can be formed by the two members, the unit member and the connecting member. In particular, when the connecting member has a sliding slope surface, the operation of driving the connecting member into the joint of the unit members can be easily performed by human power, and can be uniformly performed on the aligned unit members. Force can be applied. Therefore, it can be easily assembled at a construction site, and is easy to recycle because no metal or adhesive is required.

Further, since the logs are used almost as they are, the amount of wood used in the construction surface increases, and high heat insulation and fire resistance can be realized at low cost. hard.

Further, since a space is formed along the unit member in the interior of the structure, the strength by weight can be improved.
In addition, the space can be used for various purposes such as ventilation, drainage, wiring and piping.

When the construction surface is used as a wall surface, the timber shafts can be arranged vertically and used, which is advantageous compared to a school-room type in which the timber shafts are arranged in the horizontal direction. Further, when the unit members are connected by a connecting member made of wood, it is possible to form a construction surface in which the wood fibers are orthogonal to each other, and to stabilize the strength and reduce the deviation to achieve dimensional stabilization. I can do it.

When the width of the unit member is approximately twice the thickness, the unit member can be made into a prefabricated building material by making the reference size of the unit member correspond to the module of the building. In this case, the prefabricated unit building material becomes a common member, and the two-dimensional module can be aligned.
