DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure and a joint for a wooden structural material, and more particularly, to a joint structure and a joint for a wooden structural material having high strength, suitable for processing in a factory, and easy to perform the work. About.

[0002]

2. Description of the Related Art In a conventional wooden frame construction method, joining of wooden structural members such as horizontal members and vertical members of a frame such as columns and beams is performed as shown in parts A and B in FIG. It was joined by the structure. In the part shown in FIG.
0a, and the body difference 10c is joined to the side surface of the through pillar 10a. The connection between the through post 10a and the body difference 10c is performed by fitting a protrusion formed at the end of the body difference 10c into a recess formed on the side surface of the through pillar 10a (that is, by performing a so-called joint processing). Then, the metal parts 20 are attached to the side surfaces of the joint between them.

[0003] On the other hand, in FIG.
0b, and the end of the tube post 10b is joined to the upper and lower surfaces of the body difference 10c. The pipe column 10b and the body gap 10
c is fitted by fitting the protrusions formed at the end of the tube post 10b into the recesses formed on the upper and lower surfaces of the body difference 10c, and attaching the metal fittings 20 to the side surfaces of the joint between the two. Is being done. Also, in the part shown in FIG.
0c are also joined. In such a case, if the joint between the body gaps 10c and the joint between the tube columns 10b are located at the same position, the strength becomes weak. Therefore, one of the body gaps 10c is joined to the tube column 10b. And is joined to the other body difference 10c. At the time of this joining, joint processing is performed on the ends of each other so as to be joined, and if necessary, metal parts are reinforced.

[0004]

However, in such a joint between the wooden structural members, the applied stress may increase depending on the position where the joint is provided, and it has been desired to further strengthen the joint. In addition, in the joint structure as described above, since a joint such as a concave portion and a convex portion is provided on the surface and the end of the structural material, the effective cross section is reduced, and the strength of the member itself is reduced. Not only that, in order to form a joint such as a concave or convex part, the member may have to be made thicker to secure the effective cross-sectional area required for the member arrangement, and the wood material volume increases. There was a problem that it was irrational in the effective use of materials as a building.

[0005] In addition, since the shape of the joint such as a concave portion or a convex portion is formed by cutting an end portion of wood or the like, there is also a problem that a material processing loss is large. Furthermore,
Recently, construction methods such as cutting and edge processing (so-called pre-cutting) have been performed in the factory in advance, and a minimal work method has been used on site. Achieving a simple joint by pre-cutting has a problem in that the burden of cutting work on the machine is large and the production is irrational, and further improvement has been desired. Furthermore, as described above, it is necessary to use the through column 10a and the tube column 10b properly depending on the position where the column is installed, and it is necessary to adjust the joining position of the body difference 10c so as not to overlap, and it is difficult to standardize the material length. However, there is a problem that the production is irrational at the time of the precut processing, and further improvement has been desired from this point.

Further, in addition to forming the connection joint, the metal fittings 20 are reinforced from the side surfaces thereof, so that the metal fittings 20 are exposed to the outer surface of the wood, and the metal fittings 20 are liable to generate rust. The point that improvement is desired and the hardware 20
However, there is also a point that further improvement in fire resistance is desired because of direct contact with heat. In addition, since the mounting operation of the hardware 20 is performed at the site after the assembling operation of the structural material, there is a problem that the operation is performed in two stages and the construction is troublesome.

Next, an example of a procedure for constructing the joining structure of the wooden structural members will be briefly described. First, in the factory, the processing of the wood structural material 1 (cutting to a predetermined length and the processing of the slits 11 and the through holes 12) is performed beforehand. The plate 3 is fixed by the drift pins 4. At this time, when the plate 3b is inserted into and fixed to the end of the trunk difference 1b, the riding portion 33b fits into the groove 13 so that the through hole 12 and the fitting hole 32b are fitted.
Alignment with the in this way,
With all the work that can be performed in the factory, each member is carried to the site, and the construction of the structural skeleton is performed at the site with a minimum amount of work.

At the site, as shown in FIG.
The joint core 2 is attached to the anchor bolt 5a buried in the. At this time, the screw portion at the upper end of the anchor bolt 5a is connected to the female screw 2 on the lower surface of the column portion 2A of the joint core 2.
1a. The end of the wood structural material (base) 1 is joined to the joining core 2 fixed on the foundation 5. At this time, the columnar portion 31b of the plate 3b is inserted into the concave portion 21b of the column portion 2A of the joint core 2 as shown in FIGS. Since the concave portion 21b and the columnar portion 31b are inclined as described above, the end of the wooden structural member 1 is drawn toward the joint core 2 by its own weight, and the wooden structural member 1 and the joint core 2 Are securely joined. The above wooden structural material 1
d is firmly fixed on the base 5 by other anchor bolts not shown.

Next, the plate 3a is joined to the upper part of the joint core 2. At this time, the plate 3a
Is screwed into the female screw 21a on the upper surface of the column portion 2A. At this time, the lower surface of the riding portion 33a of the plate 3a is in surface contact with the upper surface of the column portion 2A, and the upper surface of the riding portion 33a is flush with the upper surface of the woody portion 2B.

After that, as shown in FIG. 2, the drift pin 4 is fixed on the joint core 2 in the slit 11 of the column 1a in which the drift pin 4 has already been fitted into one of the upper sides of the through hole 12. The plate 3a is inserted. At this time, the notch-formed insertion hole 32a 'is inserted in correspondence with the position of the already inserted drift pin 4.

When the plate 3a is inserted into the slit 11, the notch-shaped insertion hole 32 is formed.
Since the end of a ′ is widened, the drift pin 4 easily fits into the fitting hole 32a ′, and the position of the remaining through hole 12 and the position of the fitting hole 32a are aligned. Here, the drift pins 4 are fitted respectively. In this way, the joint core 2 and the column 1a are joined, and the lower end of the column 1a also fixes the end of the wooden structural member 1.

At the upper end of the column 1a, the plate 3a
Is already fixed (it may be fixed on site), and the joint core 2 is attached to the plate 3a at the upper end of the column 1a. Subsequent attachment of the body gap 1b and the girder are performed in the same manner as described above. FIG. 9 shows a state in which the construction is completed in this manner. As shown in FIG. 9, the respective wooden structural members 1 are securely joined to each other via the joint core 2, and thereafter, studs are provided at regular intervals between the vertically arranged wooden structural members. A structural plywood (panel) is attached to the stud to secure the surface strength of the wall.

The joint structure and the joint at the main intersection of the structural sections of the wooden structural material of the present embodiment are configured as described above. According to the joint structure and the joint of the wooden structural material of the present embodiment, When joining each of the wooden structural materials 1 and the joining core 2, it is not necessary to subject the ends of the wooden structural materials 1 to a complicated-shaped connection processing as conventionally performed, thereby reducing the effective cross section. Strong joining can be performed without reducing the strength of the member itself.

In addition, since the joint processing does not require a joining process, when joining the respective wooden structural members 1 through the joining cores 2, the members are required to secure an effective cross-sectional area necessary for the arrangement of the members. It is not necessary to increase the thickness of the member, and the member can be used rationally and effectively without increasing the extra wood material volume required at the time of the joint processing. In addition, in joining by a joint, conventionally, since the joint processing portion is arranged so that the members to be joined overlap each other, it is not necessary to secure an extra length for both members. According to the present embodiment, the length of each of the timber structural members 1 is minimized because the end surfaces of the respective timber structural members 1 are joined so as to be in contact with the side surfaces of the joint core 2. There is also an advantage that it is not necessary to secure an extra length.

Further, since the end of each wooden structural member 1 only needs to process the slits 11 and the through holes 12, there is almost no processing loss of the material as in the case of processing a joint having a complicated shape. There is also the advantage of not doing it. Further, such processing of the end portion of each of the wooden structural members 1 has a small processing load on the machine, is suitable for pre-cut processing, and can be rationally operated in production. In addition, in the case of the connection joint, it has been necessary to adjust the joining position so that they do not overlap. However, according to the present embodiment, such adjustment is not necessary, and the length of each wooden structural material 1 is reduced. Is easy to standardize, and from this point too, it is easy to perform pre-cutting and rational production is easy.

Further, there is no need to reinforce the outer surface with a reinforcing metal after joining, and the work is completed in one process, and the construction is not troublesome. Furthermore, the metal joining fitting (column portion) 2A of the joining core 2 is made of metal.
It is covered by B and is not exposed to the outside. For this reason,
In the event of a fire or the like, the joint 2A is not directly exposed to a flame and is preferable in terms of fire resistance, and is not easily exposed to moisture in the air and easily rusted, and has excellent durability. The plate 3 is also inserted and fixed in the slit 11 formed at the end of the wooden structural material 1 and most of the plate 3 is not exposed to the outside, so that it is excellent in fire resistance and durability. In addition, the ends of the wooden structural material at locations other than the main intersections of the structural sections are joined with joining metal fittings different from the joining core, but the fire resistance and durability are covered by the woody portion. It is desirable that the fittings are not exposed to the outside.

The joining structure of the wooden structural material of the present invention is not limited to the above embodiment. For example, in the above-described embodiment, the joining fitting 2A is formed as a column having a columnar shape, but may be formed into another shape other than a column. In the embodiment shown in FIGS. 2 to 8, the height of the joining core 2 is unified to 120 mm, and the height of the body difference 1b joined to the joining core 2 is also 120 mm. The height difference can take a predetermined height in accordance with the cross-sectional area for satisfying the required strength. In this case, as shown in FIGS.
b ′, 1b ″, fixed to the end of the plate 3b ′,
3b "can be easily coped with by partially changing the form. Further, in the above embodiment, the height of the joining core 2 is unified to 120 mm. The predetermined height can be set according to the strength required for secure joining, and other changes can be appropriately made without departing from the spirit of the present invention.
