DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a load-bearing wall in which a load-bearing wall panel integrally formed in advance in a factory or the like is mounted in a wall space of a main structure to be constructed on site.

[0002]

2. Description of the Related Art The construction of load-bearing walls by the conventional construction method based on on-site construction is affected by the fact that the construction conditions are affected by the weather and the season, and that it is difficult to secure skilled craftsmen and a wide work area. For this reason, work efficiency could not be improved to shorten the construction period and reduce costs. Therefore, in recent years, various paneling methods have been proposed and implemented in which a wall panel produced in advance in a factory is carried into a construction site and the wall panel is mounted on a wall space of a main structure constructed on the site. For example, JP-A-54-98015, JP-A-61-16547, and JP-A-53-70709.
This is disclosed in Japanese Patent Publication No.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a mounting structure of a load-bearing wall panel according to the present invention will be described in detail with reference to the embodiments shown in FIGS. The wall panel A includes a sizing board (soft fiber board) 1 as a structural face material, a frame body 3 mounted on one surface of the see-jig board 1 and having a stud 2 disposed therein, The wall panel A is integrally formed with the heat insulating member 4 mounted in the body 3, and is produced in advance in a factory or the like.

[0007] The see-jig board 1 used as a structural surface material has, for example, a density of less than 0.9 g / m ³ and a thickness of at least about 12 m / m specified in JIS A5909, and a vertical and horizontal dimension corresponding to that of a pillar. It is set arbitrarily according to the wall space formed by the main structure composed of the base, beams, etc., which are horizontal members. In this embodiment, each of the pillars 8, 8 whose main body structure is erected on the left and right, and horizontal members 9, 9 for connecting the upper and lower ends of each of the pillars 8, 8 horizontally, respectively, form a rectangular frame. Since the wall space is formed, the see-jig board 1 has a width dimension that can be installed between the left and right pillars 8, 8.
The height dimension is set so that it can be installed between the upper and lower horizontal members 9.

The frame body 3 is a rectangular frame composed of horizontal frame members 3a, 3a vertically and horizontally arranged, and vertical frame members 3b, 3b vertically and horizontally arranged left and right, respectively. The frame members 3a and 3b are joined to each other at four corners to be joined by a notch connection, and the frame members 3a and 3b are connected to each other via a known fixing means such as a nail. To the see-jig board 1. The stud 2 mounted in the frame 3 is disposed in parallel with the vertical frame member 3b, and the upper and lower ends thereof are the horizontal frame member 3b.
a, 3a are fixed to the horizontal frame members 3a, 3a in a state where they are fitted into tenon holes 5, 5 formed inside. The studs 2 and the frame 3 are made of wood.

The frame 3 has vertical and horizontal outer diameters set so that it can be fitted into a wall space formed by a main structure composed of columns and horizontal members such as a base and a beam. It has an outer diameter dimension that can be fitted into the wall space formed by the horizontal members 9, 9 that horizontally connect the standing columns 8, 8 and the upper and lower ends of the columns 8, 8, respectively. ing. Therefore,
The see-jig board 1 is fixed to the frame 3 in a state in which four outer peripheral edges protrude outward from the outer diameter of the frame 3 in a flange shape.

The heat insulating member 4 is formed in a rectangular shape by, for example, glass wool or the like, and the outer peripheral edge of the four sides is formed in a notched shape at the inner corners of the frame members 3 a and 3 b forming the frame body 3. Each of them is fitted between the sheathing board 1 and the stud 2 in a fitted state, and is adhered between the shank face 6 and the side surface of the stud 3 and between the sheathing board 1 and an adhesive means such as glue.

When a load-bearing wall is constructed using the wall panel A having the above-mentioned integral structure, the following procedure is carried out.
At the construction site, each column 8, 8 erected on the left and right by on-site construction and horizontal members 9, 9 such as a base or a girder connecting the upper and lower ends of each column 8, 8 horizontally, respectively. The main body structure is formed, and a square frame-shaped wall space without studs or braces is formed inside the main body structure. Further, on the inner surface side of the pillar 8 and the horizontal member 9 adjacent to the wall space, there is formed a shank face 7 cut out with a width and a thickness capable of fitting the flange-shaped portion of the see-jig board 1. deep.

The wall panel A is brought into contact with the opening edge of the main structure in a state where the frame 3 is fitted into the wall space and the flange-shaped portion of the see-jig board 1 is fitted to the shrimper 7. The wall panel A is locked and held to such an extent that the wall panel A can stand substantially independently. Therefore, nails are driven into the flanges to
In addition to connecting the see-jig board 1 to the front side of the horizontal members 9, 9, the horizontal frame members 3 a, 3 a and the horizontal frame members 3 b,
The frame member 3 is connected to the inner surfaces of the pillars 8, 8 and the horizontal members 9, 9 by driving nails from the inner surface side of 3b.

The interior and exterior finishes are applied to the wall panel A mounted on the wall space as described above, whereby the wall panel A becomes a part of the main structure, and the columns 8, 8 and the horizontal members 9, 9 in conjunction with a vertical or horizontal force-bearing wall. In the same manner as in the case of the conventional construction method, the finishing treatment described above is performed by, for example, spraying cement mortar on the surface of the sheathing board 1 or applying a lightweight concrete panel or other outer wall material to finish the exterior, and the other side of the sheathing board 1. The upper surface is subjected to base treatment with asphalt roofing, metal lath, an interior base plate, or the like so as to close the opening of the frame 3, and then interior finishing is performed by, for example, cross bonding. As a result, a closed air layer is formed in the wall body, and the closed air layer cooperates with the heat insulating member 4 to perform indoor and outdoor heat insulation.

[0014]

As is apparent from the above embodiments, the following effects can be obtained by the mounting structure of the load-bearing wall panel according to the present invention. The load-bearing wall panel is reinforced by attaching a rectangular frame-shaped wall frame and studs to the structural surface material, and a heat insulating member is attached to the inside of the wall frame. Since the work of installing the material and filling the insulation material such as glass wool is omitted,
The construction period can be shortened.

When the wall frame is fitted into the wall space formed by the main structure from the front, the load-bearing wall panel is substantially locked and held in a state where the structural face material is positioned. In a state where the main structure is pressed against the pillars and the lateral members forming the main structure so as not to slip down, the main structure can be easily attached to the main structure via fixing means such as nails, and a rectangular frame-shaped wall frame is provided. The studs mounted inside cooperate with the structural face material to form an integral load-bearing wall structure that prevents deformation of the main structure.

Further, a shank face is provided at an opening edge of the main structure adjacent to the wall space, and an outer circumferential edge of the structural face material protruding from the wall frame in a flange shape is fitted to the shank face. When the load-bearing wall panel is mounted in this state, a more rigid load-bearing wall structure can be obtained, and the structural surface materials are flush with the pillars and horizontal members constituting the main structure, facilitating exterior finishing work. Can be.
