Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a type of bearing wall which is considered to be a kind of load-bearing wall used for wooden construction.

[0002]

2. Description of the Related Art The types of load-bearing walls used in conventional wooden constructions include a panel type using structural plywood, braces, studs, lath walls, earthen walls, and siding types. Hereinafter, the conventional frame construction method, the concept of the load-bearing wall and the mechanical action of the method will be described with reference to an explanatory view as an example (see FIGS. 10 to 15).

[0003] Traditional wooden buildings in Japan are structurally “framed” (see FIGS. 10 and 11). The structure is composed of wooden columns and horizontal members (horizontal members such as beams, trunks, beams, and bases). It has been pointed out that there is a need for simplification of construction methods and labor saving due to the lack of quantity of carpenters and aging, but due to the ease of expansion and renovation and the rich living space, the traditional wooden construction of Japan We believe that construction method is the world's crowning system.

[0004] A load-bearing wall (see Fig. 12) is a wall designed to resist horizontal force (wind pressure or seismic force) acting on a building, but is not limited to the word wall. In addition to walls, braces, pillars, etc. are collectively called bearing walls. If a large number of bearing walls are placed on the outer periphery of the building and the number of openings is reduced, the safety against seismic force will increase, but the degree of freedom in designing an open living space will decrease. In addition, it is general to avoid arranging a number of load-bearing walls inside a building because of a plan.

[0005] On the other hand, if a load bearing wall is present, when a horizontal force is applied, an upward tensile force is generated at the leg portion of the load bearing wall closer to the horizontal force, and a compressive force acts on the bracing. (See FIG. 12B). Therefore, it is necessary to securely connect the column and the bracing. When the bonding is weak, the strength of the load-bearing wall decreases.

The conventional method (see FIG. 13) is used for large span buildings having no pillars inside, such as auditoriums, factories, warehouses, and the like. As shown in FIG. 14 (a), when a horizontal force P acts on a frame having a shanked column, a tensile force is generated on the left shank and a compressive force is generated on the right shank.
A bending moment acts as shown in (b), and a maximum bending moment (M _D ) is generated at the base of the stake. However, at this point, the column is often cut out to attach the stake, thereby reducing the column cross section. Therefore, the pillar will break at the base of the direction. As a countermeasure for avoiding this, a stiffening method shown in FIG. 13 is implemented, but it cannot be said that the design is beautiful.

[0007] If a pillar breaks, the building collapses. "The pillar must not break." Therefore, it is considered that a method of weakening the sword to a certain extent while making the connection between the sword and the pillar tenacious is very effective. As shown in FIG. 13 (a), the conventional mount is mounted with the mount mounting angle in the range of θ = 35 ° to 45 °, so that the connection between the column and the beam can be made tenacious. Difficult (eg, many bolts cannot be placed).

[0008] Further, according to the conventional method, as shown in FIG.
We are studying the structure as a compressed material. In addition, the scissors are often treated as a tensile material because the cross section is often thin, buckling out of the plane and having low resistance.

[0009]

The problems to be solved are described in the bullets. (B) Make sure that the pillar does not break. (B) Make the connection between the column, beam, and stubborn to be tenacious, and be able to withstand the compressive and tensile forces. (C) To make the design look beautiful. (D) Make it generally usable as a bearing wall. An object of the present invention is to provide a method with a wide range of use that can solve the problems described above.

[0010]

The parquet sculpture according to the present invention solves the above problems and is as follows. The configuration will be described using a drawing as an example.

In the example shown in FIGS. 1 to 4, the setting 1 and the receiving 3 are connected by a tenon 1 a, and the setting 1 and the receiving 3 are connected to the bending splint 2 and the joining material 4. The parquet style is integrated with As the joining material 4, bolts, wood nails, or the like are used, but it is preferable to apply a stiffening paint or an adhesive on the joining surface 4a in order to prevent the wood from corroding and fill a gap formed in the joining surface.

[0012] The connection between the first method 1 and the third method 3
The tenon 1a is hit with a wedge 1b to strengthen the joint. An adhesive is applied to the tenon 1a and the tenon 3b
And you can hit the wood from the side.

The joint 1 and the beam 7 and the joint 3 between the receiving member 3 and the column 6 are joined by connecting members 5 (bolts).
In this case, the washer may be a triangle washer 5a. In addition, the connection between the receiving member 3 and the beam 7 is
A stitch 3a is provided in the notch of the beam, and is fixed firmly with a short metal 9 and a wood screw. The receiving material 3 is made of a good material such as hinoki and zelkova, which has a grainy and sticky property. The reason will be described in the section of action.

As a material for forming the bent splint 2, a natural bent material such as a bent tree or a branched tree as shown in FIG. 16 is used, but it can also be made of laminated wood or FRP.

In the example shown in FIGS. 5 to 8,
This is an integrated parquet style in which a is joined to the receiving style 3 with a joining material 4. The root bending instruction 2a is obtained by cutting out the positioning instruction and the bending splint according to the first embodiment integrally from the root bending tree shown in FIG.

The feather plate bolt serves as the tenon of the setting method 1 shown in the first embodiment. However, if the rooting method 2a and the receiving method 3 can be sufficiently joined with the joining material 4 (bolt or the like), the bolt is not used. You may.

The joining surface 4a between the root bending method 2a and the receiving method 3 is preferably a table joint 4b. The reason is to surely transmit the shear force acting on the joint surface 4a.

The joining between the receiving member 3 and the beam 7 is performed by inserting a miscellaneous tenon 3a into a notch of the beam and firmly joining it with a box metal member 8. Further, the connection with the column 6 is performed by the connecting member 5 and the connecting bolt 10. The tie bolt 10 is a reinforcing connecting material for the case where the buckle resists a compressive force and a tensile force.

[0019]

Next, the operation of the present invention will be described with reference to an explanatory diagram as an example. The mechanical action of the conventional method (see FIG. 15A) is that the maximum bending moment (M _max at the root (point D) of the method)
= M _D ), and it is described in the section of the prior art that the possibility that the column is broken is higher than this point.

In the case of the parquet according to the present invention, FIG.
As shown in b, the compressive force acting on the bearing is transmitted to the bearing 3. It is considered that the compression stress distribution is a complicated distribution. Assuming that the concentrated load acts on the receiving base 3 for simplicity, a maximum bending moment occurs at the application point K at the receiving base 3 as shown in the figure. This indicates that the column can be prevented from being broken if the receiving member 3 is broken by the bending moment before the column is broken.

Although there is a method of making the conventional sash weaker and preventing the column from being broken, the destruction of the conventional sushi is buckling,
Destruction is shocking (fragile). Therefore, it is difficult to make the structure flexible against seismic force (horizontal force).

In the case of the parquet slab according to the present invention, the collapse of the building can be prevented if the stub 1 is made strong and the receiving slab 3 is broken by the bending moment before the column is broken. In addition, bending fractures exhibit sticky fracture properties. Therefore, the structure can be made flexible against seismic force. In addition, the first method 1 and the second method 2a are shown in FIG.
As shown in FIG. 5, the support condition of the material end is almost fixed, the buckling length is short, and the end connection is strong against buckling.

The tensile force and material end moment acting on the beam 1 and the root bending 2a from the beam 7 are applied to the beam receiving member 3 by the bonding force of the bending splint 2, the tenon, the blade bolt 11, and the bonding material 4. Is transmitted. Further, it is transmitted to the pillar from the receiving direction 3 and resists external force (earthquake force, wind pressure). Thus, the joint connection between the column, beam and parquet slab determines the tensile strength of the slab.

As shown in FIG. 15B, the stake mounting angle of the parquet sword of the present invention is set in the range of θ = 5 ° to 20 °. Therefore, two or more connecting members 5 (bolts) used for joining the pillar, the beam, and the parquet board can be connected, and the connection becomes tenacious.
Furthermore, as shown in Embodiments 1 and 2 (FIGS. 1 and 5), the receiving mortise 3a and the tie bolt 10
Thus, a large tensile force can be resisted. This makes it possible to incorporate ramen structures into wooden buildings.

As described above, the present invention is characterized by having a structure that withstands a compressive force and a tensile force and has a strong tenacity.

The tenon 1a is inserted into the tenon mortise 3b, and is connected by hitting a wedge. The mortise 3b is preferably inclined toward the wedge. Further, an adhesive is applied to the joint surface 4a between the holding member 1 and the receiving member 3, and the bent splint 2 is attached and fixed with a clamp or the like. Next, a through hole for the joining material 4 (bolt or the like) is provided by a drill, and the joining material 4 is firmly joined. When a bolt is used for the joining material 4, it is preferable to use a high-strength brass bolt so as not to corrode wood. When using other bolts, it is advisable to apply a small amount of adhesive to the bolts and strike the bolts.

A description will now be given of the attachment of the parquet slab (see FIG. 1). The parquet swords are inserted into the cutouts of the pillars 6 and 7 from the side of the pillars. The receiving member 3 and the column 6 are joined by the connecting member 5. Further, the receiving member 3 and the beam 7 are joined to the short stud 3a provided in the receiving member 3 and the beam 7 with a short metal 9 and a wood screw. In addition, short hardware 9

【The invention's effect】

(Foreword) In Japan, rural areas have lost vitality due to the concentration of population in cities and the sophistication of urban functions. In particular, forestry is sluggish due to the aging society, shortage of workers and skilled workers, lack of effective use of raw wood, and the like. However, there is an abundant and huge market in Japan, and there is also a potential demand in the housing industry, such as renovations, seismic reinforcement, etc. Therefore, we believe that the future of forestry will be opened if we increase the added value by processing unused tree species such as thinned wood and developing new products. The effects of the invention will be described below.

By strengthening the direction, the seismic retrofit of the conventional frame construction method can be performed, and the number of wall-type load-bearing walls can be reduced. This increases the degree of freedom of the plan and provides a good living space.

An existing house can be easily extended or remodeled and seismic reinforcement can be easily implemented, and a beautiful design can be obtained.

As shown in FIG. 16, the added value of the unused tree species is increased, which contributes to the activation of forestry.
