This was developed in connection with invention No. 42062.

(Prior Art) In view of the current situation in which the number of buildings with wooden frame structures has been sluggish recently, the applicant of the present application has
As has already been developed and completed through the invention of Patent Application No. 60-3697, the cross-sectional area is approximately four times that of the previous one (compared to the previous standard member size of 10.5 cm square). By adopting a frame member equivalent to a 21 cm square member, especially a through column, and realizing an innovative wooden frame structure in which the column base is directly embedded and fixed in the foundation, the foundation We were able to strengthen the bonding strength between the section and the frame structure, omit reinforcing intermediary members by using large cross-section members, and simplify the construction process.

In order to make this basic structural form more practical, we not only changed the overall structural form, but also
We are continuing to improve and develop each part with the aim of further improving our technology.

The above-mentioned invention of Japanese Patent Application No. 60-42062 was also realized in the process, and in particular, in the overall structural form, the attachment structure of the through columns and horizontal members,
In other words, this is an attempt at a new proposal for the joint structure, and has already improved its assembly workability, cutting workability,
Furthermore, in terms of joint strength, etc., it has achieved a level of effectiveness that was not possible with previous products.

This invention has been developed and completed in order to further improve the Shiguchi structure that has already been developed and put into practical use, and to make it even more practical.
Its configuration is as detailed below.

(Structure of the Invention) As can be clearly understood from the representative embodiments shown in the drawings, the joint structure of the present invention basically consists of a wooden connecting member 3, a joint part 11 of a through-post 1, and a horizontal member. This is realized by the joint part 21 of 2, the wedge material 4, and the wheel guide 5.

First, the wooden connecting material 3 is made of straight natural wood or laminated wood, and vertical notches 31, 31 are formed on both sides near the ends of the material, and the upper surface of the central portion or An interlocking notch with a predetermined width is provided on the lower surface (the upper surface of the upper connecting material 3 and the lower surface of the lower connecting material 3 of the pair of wooden connecting materials 3, 3 used in a phased manner). 32 is formed and configured.

The joint portions 11 and 11' of the through-post 1 are insertion holes 1 having a cross section longer than the cross section of the wooden connecting material 3.
2 and 12' are formed so as to intersect vertically in phase with each other, and at both ends of each insertion hole 12 and 12',
Relatively shallow mortises 13, 13' are formed with a cross section into which the entire cross section of the butt end of the horizontal member 2 can be inserted.

The joint portion 21 of the horizontal member 2 has a planar shape that is approximately half of the planar shape of the wooden connecting material 3, and has a shape corresponding to the notch portion 32 of the wooden connecting material 3. The mortise 23 formed with the cutout portions 22, 22 is formed on the upper end surface or lower end surface of the butt end (the connecting material 3 located above the pair of wooden connecting materials 3, 3 used in a phased manner). It is formed to a predetermined depth so as to reveal its planar shape on the upper end surface of the horizontal member 2 that fits into the connecting member 3 located below, and on the lower end surface of the horizontal member 2 that fits with the connecting member 3 located below. It is something.

The wedge material 4 has a thickness cross section that is slightly larger than the longitudinal dimension difference between the cross section of the insertion holes 12, 12' in the joint portions 11, 11' of the through post 1 and the cross section of the wooden connecting material 3, Through-post joint part 11, 11'
By being inserted into the insertion holes 13, 13', the wooden connecting material 3 is pushed up or down (in a pair of wooden connecting materials 3, 3 used in a phased manner,
Push up against the connecting material 3 located above, push down against the connecting material 3 located below), pass through the interlocking part 32 of the wooden connecting material 3 to the pillar joint parts 11, 1.
1', and wooden connecting material 3 to the through post 1.
It serves the function of connecting and integrating the

2 and 31, and the wooden connecting member 3 and the horizontal member 2 are integrated by the interposition of the wheel guide 5.

The through post 1 is a wooden post with a relatively large cross section, for example, 21 cm square (7 cm square), and may be made of natural wood, laminated wood, or the like. Although not particularly shown in the diagram, the column base is fixed to the foundation of the building in an embedded manner (usually fixed via column base fixing metal fittings that have been buried and fixed in advance within the foundation). It will be convenient if it is done.

The horizontal members 2 include the outside of the trunk sills, beams, etc., girders and foot reinforcements,
All members other than the pillars that make up the large-scale equiaxed set are included. The cross-sectional dimension is at least narrower than the cross-sectional dimension of the through-post 1. For example, if we take a trunk sill as the horizontal member 2, it is the most commonly adopted dimension. Approximately 12cm wide (4 sun), height approximately 36cm (1 shaku 2 sun)
The entire cross section of the butt end must be able to be completely inserted into the side surface of the through post 1 at the location where the joint portion is planned to be formed.

The horizontal members 2 that are inserted and connected to the through-posts 1 face each other, and the through-posts 1
However, when horizontal members 2, 2... are connected vertically and horizontally to the joint portion of the through-post 1 where the joint section is planned to be formed, this wooden connecting material 3 , are arranged vertically and horizontally in an intersecting manner, so they are planned to pass through the through-post 1 in vertically phased fashion.

Fig. 1 is a partially exploded perspective view of a joint structure realized from the above configuration, Fig. 2 is a horizontal sectional view of the main part, and Fig. 3 is a vertical sectional view of the main part. .

In addition, the building consisting of the Shiguchi structure of this invention,
In terms of structural strength, it is possible to achieve a structure that does not require any braces at all, but in order to comply with the current building regulations and other circumstances, braces are only added as an auxiliary measure, although they are not shown in the drawings. In some cases, a wooden frame structure having a configuration similar to that of the present invention may be realized.

On the other hand, from the viewpoint of structural strength in the horizontal plane, it is possible to arrange flint beams at each joint part as in the past to realize a structure that can cope with deformation in the horizontal plane. In addition, by directly fitting and integrating floor structure panels (not shown) between the adjacent horizontal members 2, 2, it is also possible to realize a framework structure in which the above-mentioned flint beams are completely omitted. It becomes possible.

Each member formed in the above-mentioned configuration is first assembled by temporarily attaching and erecting the through-posts 1, 1, etc. in a grit-like arrangement according to a predetermined plan view. , 11', one insertion hole 1 in
A wooden connecting material 3 is inserted into 2 and fitted in such a manner that both ends protrude from the through-post 1. Subsequently, another wooden connecting member 3 is inserted and fitted in the same manner from the other insertion hole 12'.

Then, the lower end or upper end of each of the insertion holes 12, 12' (in the pair of upper and lower insertion holes that cross each other, the lower end of the insertion hole 12 located above, and the lower end of the insertion hole 1 located below)
2', the upper end), and the lower surface or upper surface of the wooden connecting members 3, 3 that are already in a fitted shape (the connecting member located in or above the pair of wooden connecting members 3, 3 used in a phased manner) Forcibly drive wedges 4, 4... between the lower surface of the wooden connecting material 3 (for 3) and the upper surface of the connecting material 3 located below, so that each wooden connecting material 3, 3 passes through its center correctly and aligns with the axis of the pillar 1. Fix it so that it matches. As a result, the wooden connecting materials 3, 3 are vertically phased and intersected,
Both end sides of each of the wooden connecting members 3, 3 are protruded with equal lengths in the front and rear, left and right directions of the through-post 1.

The joint portions 21 of the horizontal members 2 to be connected are fitted to each end of the wooden connecting members 3 which have become protruding in this way, and the ends of the horizontal members 2 are formed at the ends of the insertion holes 12. Insert completely into mortise hole 13. Then, since the vehicle information notch 31 of the wooden connecting member 3 and the vehicle information notch 22 of the horizontal member 2 correspond to each other to form a vehicle information insertion hole, the vehicle can be inserted into the vehicle information insertion hole. When the screws 5 are forcibly driven in, each of the horizontal members 2, 2... will pass through and fit through the through post 1, with the end of each horizontal member 2, 2, etc. fitting into the mortise 13 of the through post 1. 3 to complete the joint structure in the wooden framework structure of this invention.

It goes without saying that the procedure for assembling the joint part is not necessarily limited to the procedure described above. , 3 to the joint part of the pillar 1 before being handled, or even several horizontal members 2 are connected and fixed on the ground before being erected. The most suitable procedure can be adopted accordingly.

In the figure, reference numeral 6 denotes a stopper that is employed as needed, and is employed to enhance the connection strength of the horizontal member 2 to the wooden connecting member 3. In addition to the rectangular cross-sectional shape, the stopper 6 can have a circular cross-section, and when a circular cross-section is adopted, it is advantageous in terms of resistance to shear failure. This has been experimentally proven through strength tests of this Shiguchi structure.

Note that in the above embodiment, the horizontal members 2, 2 are connected around the through-post 1 and are crossed, but the horizontal members 2, 2 are connected around the through-post 1 in a planar, straight shape, or in a T-shape. In addition to being possible based on the same idea even when connecting in a shape, it is also possible to adopt the same method even when the cross section of the through column is not a normal rectangular cross section.

(Operation and Effect) The joint structure in the wooden framework structure of the present invention, which is constructed as described above, has a complete insertion-fitting structure in which the entire cross section of the cross section of the horizontal member 2 is connected to the through post 1, which has a relatively large cross section. In addition, it is firmly connected to each frame member by a wooden connecting material 3 of the same quality, and the connecting material 3 is attached to one side of either the upper end surface or the lower end surface on the wood end side of the horizontal member 2 (mostly , the surface that becomes the wall forming surface and becomes hidden) (even in this case, it looks like wood of the same quality has been embedded, so there is no sense of discomfort at all), so the through column 1
The intersection of the horizontal frame member 2 and the cross member 2 has a very clean structure, and not only is there no problem with the design effect even if the joint part is exposed as it is, but on the contrary, it actively enhances the aesthetic effect as it is. It can even be said that it can be used as a shiguchi part.

An even more important effect is that as the through columns 1, horizontal members 2, and wooden connecting members 3 are all made of wooden materials, the deformation stress due to external force applied to the joint part is approximately uniform, and each structure The members do not deform and move individually, and it is possible to realize a much more reliable joint, especially compared to the conventional fastening fittings. Therefore, with conventional products, there would be looseness at the joints unless additional seaming work was done mid-way, but with the product of this invention, there is almost no such worry.
It is possible to realize a robust shikuchi structure.

In particular, the shapes of the insertion hole 11 formed in the through-post 1 and the wooden connecting material 3 are made simpler than those devised in Utility Model Application No. 60-42062, which was developed by the applicant himself. In addition to simplifying the combination with the wooden wedge material 4 and the wheel guide 5, the effect of facilitating the processing of each member can be said to be extremely remarkable.

Furthermore, if disassembly becomes necessary for some reason, the wooden connecting members 3, horizontal members 2, and through-pillars 1 can be easily disassembled by removing the wedge members 4 and the wheel guide 5. It has the excellent feature that at least the wooden connecting members 3, the horizontal members 2, and the through columns 1 can be removed with almost no damage and can be fully reused.

As mentioned above, the wooden frame structure of the present invention has a wooden frame structure that is more similar to the column base-embedded type wooden frame structure that employs relatively large cross-section members, which the applicant has developed himself. In addition to making the structure more efficient and solidifying its structural strength, it also contributes to improving economic efficiency through improvements in workability, standardization of components and construction methods, and is of great use in the advancement of architectural styles. The effect it can have on revitalizing sluggish wooden buildings can be enormous.
