Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a load-bearing panel unit and a horizontal member such as a base or a beam in a wooden building mainly composed of wood and using connecting hardware and a load-bearing panel. Related to the connection method.

[Problems to be solved by conventional technology and invention]

Conventional wooden buildings have problems such as difficulty in unitization, long construction time, and the need for craftsmen with special skills. was difficult.

On the other hand, the use of specially processed high-quality wood and the use of steel parts as load-bearing panels increase the degree of freedom in designing spans and openings. Attempts have been made to streamline construction and improve quality by making space design possible and by actively using connecting hardware for connections and the like.

The method for forming a building load-bearing panel of the present invention has been invented based on the above background.

[Means for solving the problem]

The method for forming a structural load-bearing panel of the present invention is a method for forming a structural load-bearing panel in which a lattice member is disposed between a central vertical member and vertical members on both sides parallel to the vertical member and upper and lower horizontal members. The upper surface of the lower horizontal member has a rising portion that sandwiches the lower end of the central vertical member from both in-plane directions, and the rising portion has a guide groove that opens in an out-of-plane direction of the load-bearing panel. The connection fitting thus formed is fixed, the lower part of the upper horizontal member has a hanging part that sandwiches the upper end of the central vertical member from both sides in the in-plane direction, and the hanging part has an opening outside the plane of the load-bearing panel. A connection fitting having a guide groove formed therein is fixed, and a load-bearing panel unit composed of the central vertical member and lattice members on both sides is attached to a lower end portion and an upper end portion of the load-bearing panel unit. And the lower end of the lattice members on both sides The flat portion and the upper end flat portion are temporarily fixed with penetrating bolts penetrating therethrough, and the rising portion of the connection fitting fixed to the lower horizontal member,
Sliding between the lower end of the central longitudinal member and the lower end flat portion of the lattice member, and the hanging part of the connection fitting fixed to the upper horizontal member, the upper end of the central longitudinal member and the lattice member The through-bolt is engaged with the guide groove of the connection fitting from the out-of-plane direction while being slid between the upper-end flat portion, and the through-bolt is tightened. It is characterized by connecting with.

The applicant of the present application has previously described, for example, Japanese Patent Application No. 63-1599 as a load-bearing panel unit formed in this manner.
No. 60 (see JP-A-1-318637), a vertical member such as a column or a stud, and a steel pipe or the like are processed into a lattice shape to form a flat contact portion with the vertical member. We have developed a lightweight, high-strength, easy-to-unit load-bearing panel that allows parts to be joined to vertical members with bolts, etc., and can bear large horizontal forces within the frame of a wooden building. .

〔Example〕

 Next, the illustrated embodiment will be described.

FIG. 2 shows an example of the arrangement of load-bearing panels in a wooden house. The frame is composed of a load-bearing panel incorporating a load-bearing panel unit 1, a wooden pillar 2, a wooden beam 3, a wooden hut set 4, and the like. It is configured.

FIG. 1 shows the structure of the load-bearing panel and the state of its connection. The load-bearing panel is a vertical member at the center as a stud or the like.
Lattice members processed from 1a, pillars 1b on both sides, thin steel pipe, etc.
1c and upper and lower horizontal members 5.

According to the present invention, the central vertical member 1a and the lattice member 1c are assembled in advance, and the unitized load-bearing panel unit 1 is assembled.
Are mounted in a space surrounded by columns 1b on both sides and upper and lower horizontal members 5 such as beams and bases.

As shown in the figure, the central vertical member 1a and the lattice members 1c on both sides of the load-bearing panel unit 1 are fixed at the intermediate portion by bolts 7 via connection metal members 6 on a flat plate.
As will be described in detail later, the upper and lower ends are temporarily fixed by penetrating bolts 9 penetrating the upper and lower ends of the vertical member 1a and the upper and lower ends of the lattice member 1c, respectively. The lattice members 1c on both sides of the load-bearing panel unit 1 and the columns 1b on both sides can also be connected by bolts 7.

The connection between the upper and lower horizontal members 5 and the load-bearing panel unit 1
This is performed via connection hardware 8 fixed to the surface of the horizontal member 5 to which the load bearing panel unit 1 is attached, that is, the upper surface of the lower horizontal member 5 and the lower surface of the upper horizontal member 5. The connecting hardware 8 has a mounting base 8a for the horizontal member 5 and a rising portion 8b or a hanging portion 8b 'for sandwiching the lower end or upper end of the vertical member 1a at the center of the load-bearing panel unit 1, and the rising portion 8b and the hanging portion 8b.
Guide grooves 8c are formed in b 'so as to open in the out-of-plane direction of the load-bearing panel unit 1, respectively.

FIG. 3 shows the details of the lower end connecting portion, in which the vertical member 1a at the center of the load-bearing panel unit 1 is placed on the base 8a of the connecting hardware 8.
Of the connecting member 8 abuts on the lower side surface of the central vertical member 1a, and the lower end flat portion of the lattice member 1c abuts on the outer side thereof. Fixed. In the figure, reference numeral 10 denotes a nut. The upper end connection portion has the same structure.

By forming the guide groove 8c in the connecting metal member 8, when the load bearing panel unit 1 in which the central vertical member 1a and the lattice member 1c are unitized as shown in FIG. 1 is attached, the upper and lower ends of the lattice member 1c are penetrated. With the bolts 9 temporarily fixed, the rising portions 8b of the connection hardware 8 can be slid between the central vertical member 1a and the lattice member 1c, and can be securely fixed by tightening the through bolts 9 as they are. it can.

[Effect of the Invention] In a state where the load-bearing panel unit is assembled, between the rising portion and the hanging portion of the connection hardware fixed to the horizontal member such as the base and the beam,
Since the end of the vertical member at the center of the load-bearing panel can be slid in from one direction and attached, the workability of the entire frame can be improved.

Since the lattice member of the load-bearing panel unit can be connected to the vertical member at the center and the horizontal members such as the base and the beam, a single through-bolt can be used in the form of a single through-bolt that has been installed in the load-bearing panel unit in a temporarily fixed state. The joining structure is simplified, the number of parts is small, and workability is good.

Since the guide groove formed in the connection metal member is opened in the out-of-plane direction of the load-bearing panel, the load-bearing panel unit can be slid into a predetermined position with the through bolts attached, and can be easily attached.
