Description

Detailed Description of the Invention (Object of the Invention) The present invention relates to a novel wooden frame structure and a joint structure used in the wooden frame structure,
Showa, which has already been developed by the applicant
It was developed in connection with several inventions, including the 1960 Patent Application No. 3697 invention.

(Prior art) In addition to the rise of lightweight steel structures, panel structures (so-called two-by-four structures), and other easily assembled structures, the number of construction starts using wooden framework structures has slowed in recent years due to rising lumber prices and carpenter labor costs. I'm feeling sluggish.

However, the attachment to the wooden frame structure, which is Japan's traditional architectural style, remains deep-rooted, and this trend is particularly evident in the field of residential construction. Despite this user-side background, there are various possible reasons why the number of construction starts has not increased as much as in the past, but one of the biggest reasons is the above-mentioned soaring construction costs. Related to this, there may be current problems such as not being able to meet the needs for high-end specifications within a certain budget.

Based on an invention already proposed by the applicant, we have developed an innovative wooden frame structure that can overcome the shortcomings of conventional structures.
succeeded in completing it.

The wooden frame structure of this completed invention has a frame member whose cross-sectional area is approximately four times that of the previous one (21cm square member, compared to the previous standard member size of 10.5cm square). The column base is directly embedded and fixed in the foundation, which strengthens the bonding strength between the foundation and the frame structure, and eliminates the need for reinforcing intermediary members by using large cross-section members. We were able to simplify the construction process. Therefore, although this proposed invention naturally satisfies the intended purpose, the applicant of this application intends to continue its improvement and development with the aim of further improving the technology. ing.

This invention was realized in the process, and its configuration is as detailed below.

(Structure of the Invention) As can be clearly understood from the representative embodiment of the invention shown in the drawings, the present invention is a comparative example in which the column base 14 is fixed to the foundation 6 in a telescoping manner. Large cross-section wooden through columns 1 are erected in a grid-like arrangement according to the plane of the building, and between the through columns 1, 2 horizontal members such as shells and beams having a width smaller than the cross-sectional dimension of the through columns 1 are installed. The entire cross-section of each butt end is abutted against the side surface of the through-post 1 so as to be slightly inserted, and the cross-section members, such as body inserts or beams, which are arranged opposite each other through the through-post 1 are connected to each other. 2, 2 are a wooden frame structure in which the pillars 1 are connected and integrated by wooden connecting members 3 which pass through and intersect vertically at the joint part of the through-post 1.

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. The column base 15 is fixed to the foundation part 6 in an embedded manner, and usually, the column base fixing metal fitting 6 is buried and fixed in advance in the base part 6.
1. However, the structure of the metal fittings 61 is not limited, and the structure of the foundation part 6, that is, a cloth foundation as in the embodiment, a solid foundation, an independent foundation, or the same cloth foundation. However, depending on the structural scale of the framework structure that forms the upper structure, it is possible to adopt the optimal one as appropriate.

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 are opposite to 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 pillar 1 in vertical and vertical phases.

Figure 1 shows a partial perspective view of the wooden frame structure realized from the above configuration, and from the viewpoint of structural strength in the vertical plane, it is possible to achieve a structure that does not require any braces at all. However, in order to clear the current building regulations and other circumstances, although not shown in the drawings, braces are provided as an auxiliary arrangement to realize a wooden frame structure with a configuration similar to that of this invention. Sometimes.

On the other hand, from the viewpoint of structural strength in the horizontal plane, it is also 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. By directly fitting and integrating the floor structure panels 7 between the adjacent horizontal members 2 and 2, as shown in FIG. It becomes possible.

The fitting structure of the floor structure panel 7 between the adjacent horizontal members 2, 2 is extremely simple and strong due to the structure employing panel hooks 8, as typified by the embodiment shown in FIG. Realized. That is, a fitting groove is formed in which the panel hanger 8 is fitted and integrated at a position below the upper end surface of the horizontal member 2 by a distance approximately equal to the thickness dimension of the panel 7, and a fitting groove is formed in the same place in advance or through the pillar 1. After connecting and fixing the horizontal member 2 to the panel hanger 8, the panel hanger 8 is used as a material to integrate the prefabricated floor structure panel 7 to the horizontal member 2 by nailing 9 or other means. If this is done, the deformation and movement of the horizontal members 2, 2, etc. around one through-post will be reliably prevented, and the troublesome process of cutting and assembling the wood will be omitted, resulting in a simple structure. It becomes possible to realize a wooden framework.

An example of the most ideal structure of the joint part employed in the wooden frame structure of the present invention having the above structure is shown in FIGS. 3 and 4.

That is, a main through hole 12 having a cross section through which the wooden connecting material 3 can be freely inserted is provided at the location where the joint portion is planned to be formed in the through post 1, and the main through hole 12 is connected to the main through hole with a width smaller than the width of the main through hole 12. A through hole 11 having a substantially convex cross section consisting of a drop-in through hole 13 is traversed and formed, and in a direction perpendicular to the insertion hole 12, a cross section having a substantially inverted convex cross section is formed by inverting the cross section of the through hole 11 vertically. The insertion holes 11' are formed such that only the main through holes 12, 12' intersect with each other in the same horizontal plane at the center position of the joint portion of the through post 1, and each of the insertion holes 11, 1
A joint portion of the through-post 1 is formed by forming a mortise hole 14 at both ends of the cross-member 1' with a cross-section and shape that allows the entire cross-section of the butt end of the horizontal member 2 to be inserted thereinto.

On the other hand, a completely separate wooden member is used to form a wooden connecting member 3 having a generally I-shaped planar shape with bulges 31, 31 formed at both ends and longer than the cross-sectional dimension of the column throughout the entire length.

On the other hand, the horizontal members 2, 2, .
A mortise 21 is formed to a predetermined depth so that only the portion corresponding to the bulge 31 has a planar shape with a play length, and the planar shape is exposed on the upper or lower end surface on the butt side. Ru.

Furthermore, each insertion hole 11, 1 of the joint part of the through-post 1
The cross section of the main through holes 12, 12' at 1' is slightly larger than that of the main through holes 11, 11'.
A wedge member 4 that functions as a wedge between the wooden connecting material at the same location by being inserted into the wedge member 4, and a wooden connecting material bulging portion 31 of the mortise hole 21 formed on the wood end side of both ends of the horizontal member 2. A wedge 5 is provided as a separate member, which functions as a wedge between the wooden connecting member 3 and the wooden connecting member 3 fitted in the same position by being inserted through the corresponding part.

Each member formed in this way is first placed in a grid-like arrangement according to a predetermined plan view, and the pillars 1, 1...
In the process of temporarily attaching and erecting, the wooden connecting material 3 is inserted into one of the insertion holes 11 in the joint part of each through-post 1 through its main through-hole 12, and the bulging parts 31 at both ends are inserted.
31 protrudes from the through-post 1, the wooden connecting material is dropped into the through-hole 13 and fitted into the through-hole 13. Next, insert another wooden connecting material 3 into the main through hole 12' of the other insertion hole 11' in the same way, and drop it into the through hole 1.
3'. In this state, each wooden connecting material 3,
3 are vertically phased and intersecting, and each main through hole 13, 13' is hollow, so that wedge members 4, 4 can be inserted from both ends of each main through hole 13, 13'. . . . are forcibly driven in, and each wooden connecting member 3, 3 is fixed so that its center passes through the center correctly and matches the axis of the pillar 1. As a result, the respective bulging portions 31, 31, .

The mortises 21 of the horizontal members 2 to be connected were fitted into both ends of the wooden connecting members 3 which had become protruding in this way, and the ends of the horizontal members 2 were formed at the ends of the insertion holes 11. Insert completely into mortise hole 14. Then, a play space is created between the wooden connecting material bulge 31 and the corresponding horizontal frame mortise 21, so when the wedge 5 is forcibly driven into the play space, each horizontal frame 2, 2... are the opposite horizontal members 2, 2, with their butt ends fitted into the mortises 14 of the through post 1, respectively.
They are firmly connected and fixed to each other via the through-post 1,
The joint section in the wooden framework structure of this invention is completed.

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 may be connected and fixed on the ground and then erected, depending on the situation. The most suitable procedure can be adopted. In the figure, 62 is an anchor bolt.

Furthermore, although the above embodiment shows an example in which the horizontal members are connected around the through columns, the same idea applies even when connecting the horizontal members to the through columns in a planar, linear or T-shape. In addition to being able to be implemented based on the following, it is also possible to adopt it in the same way even if the cross section of the through column is not a normal rectangular cross section.

(Function and Effect) The wooden frame structure of the present invention, which has the above-described configuration, employs a basic structure in which wooden columns with relatively large cross sections are erected and fixed to the foundation in a column-embedded manner. The joint structure with the horizontal members connected between each column is realized by a complete insertion-fitting structure of the entire cross section of the end of the horizontal members, which is possible only by using large cross-section members. It is firmly connected by a connecting material of the same quality as the assembled members, and the connecting material is either one side of the upper end surface or the lower end surface on the wood end side of the horizontal member (in most cases, it is the surface that becomes the wall forming surface and is 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)
Therefore, the intersection of the pillar and the horizontal member becomes extremely clear, and not only does it have no problem with the design effect even if the joint part is exposed as it is, but on the contrary, it actively improves the aesthetic effect as it is. It can even be said that it has the potential to become a Shiguchibe that should be adopted to improve the quality of the work.

An even more important effect is that because the columns, horizontal members, and connecting materials are all made of wood, the deformation stress caused by the external force applied to the joint part is almost uniform, and each component is made of wood. This means that it will not deform or move apart, making it possible to create a much more reliable joint, especially compared to the conventional fastening fittings. In addition, with the previous model, wobble would occur at the joint unless additional seaming work was done mid-way, but with the product of this invention, there is almost no such necessity, and the frame assembly It is possible to maintain an accurate structure for a long period of time.

This effect is more pronounced in the case of a joint part that is made up of an insertion hole with a substantially convex cross section formed in a pillar, a wooden connecting material with bulges formed at both ends, a wooden wedge member, or a combination of wedges. become remarkable.

On the other hand, the wooden frame structure of the present invention, which is composed of a joint section having the above-mentioned characteristics, has no metal fittings or other foreign objects that could be an obstacle on the side surfaces of the horizontal members. It is extremely easy to fit a floor structure panel of a predetermined thickness between adjacent horizontal members, and by fitting and fixing this floor structure panel, deformation and movement of the horizontal members in the horizontal plane around the columns is completely prevented. , areas that would normally have to be reinforced with flint no longer need to be reinforced.
Not only is it advantageous in terms of economy and workability, but it also has an excellent appearance.

As mentioned above, the wooden frame structure and its joint structure of the present invention are based on a column-mounted wooden frame structure that employs a relatively large cross-section member that has been developed by the applicant. In addition to making the structure more efficient and solidifying its structural strength, it contributes to improving economic efficiency through the standardization of components and construction methods, and it can also be of great help in upgrading architectural styles. , the effect of revitalizing sluggish wooden buildings can be enormous.
