DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A mounting structure for a load bearing wall according to the present invention will be described below in detail with reference to the illustrated embodiments.

The wall panel 1 used for the mounting structure of the load-bearing wall is manufactured in advance in a factory and carried into a building site, and is fitted into the wall space of the frame structure constructed on-site to be integrally attached to the load-bearing wall structure. It is what constitutes.

As shown in FIGS. 1 and 2, the wall panel 1 includes vertical frame members 3 and 3 which constitute a part of a composite column formed by dividing an ordinary main column into halves on both sides. The upper and lower horizontal frame members 5 and 5 are horizontally arranged in such a manner that the upper and lower end portions of the vertical frame members 3 and 3 are connected to each other. A rectangular frame-shaped wall frame 6 is formed by a plurality of studs 4 whose upper and lower ends are respectively connected to the horizontal frame members 5 and 5, and the tenon portion 2 is provided at the upper and lower ends of the vertical frame members 3 and 3. , 2 are vertically formed.

A heat insulating material 7 is filled between the vertical frame member 3 and the studs 4 of the wall frame 6 and between the studs 4 and 4, and one surface of the pair of rectangular frames is covered with, for example, sheathing. A structural face material 8 made of a board (soft fiber board) is attached, and a heat insulating sheet 16 and a decorative plate 17 are attached to the other surface.

The wall panel 1 described above is installed laterally between main pillars which are erected on four sides of a building (not shown), for example, a foundation and a barrel or a barrel and an eaves.
A plurality of sheets are mounted in parallel in the wall space formed between the vertical frame members 3, 2 via the tenon portions 2, 2.
While connecting the upper and lower ends of 3 to the horizontal members 10, 10,
The vertical frame members 3, 3 of the adjacent wall panels 1, 1 are connected to each other, whereby the wall panel 1 constitutes a bearing wall panel having a frame structure.

As a structure for connecting the adjacent wall panels 1, 1 to each other, for example, as shown in FIG. 3, one and the other vertical frame members 3, 3 are joined to each other on the outer side surfaces of the interleaving surface 3a. , 3a respectively, and a thin plate 3b made of rubber or a flexible synthetic resin between the interleaving surfaces 3a, 3a.
Are connected together by an adhesive or the like.

As another connecting means, for example, as shown in FIGS. 4 and 5, a concave groove U is formed in the joint surface of the vertical frame members 3, 3.
₁ , U ₂ , U ₃ , U ₄ are provided, and a rigid engaging member 18 is inserted into the concave grooves U ₁ , U ₂ , U ₃ U ₄ and integrally connected by an adhesive or the like.

Further, as a structure for connecting the adjacent wall panels 1, 1 to the horizontal members 10, 10, as shown in detail in FIGS. 6 and 7, the horizontal members 10, 1 are enlarged.
0 is a mortise hole 11, 11 into which the above-mentioned tenon portions 2, 2 can be fitted.
And a dowel hole 2b formed so as to traverse the mortises 11 and 11, and the tenon portion 2 is provided with a dowel hole 2a communicating with the dowel hole 2b.

When the wall panel 1 is connected to the horizontal member 10, the tenon portions 2, 2 of the adjacent vertical frame members 3, 3 are fitted into the mortises 11, 11 to form the hollow of the horizontal member 10. The drift streak 2c inserted into the dowel hole 2b from the punched hole side is driven into the dowel hole 2a of the mortises 2 and 2 so that the tip end is inserted into the dowel hole 2b on the other side, and the two are press fit. Tighten.

As a result, the upper and lower ends of the vertical frame members 3 and 3 on both sides of each wall panel 1 and 1 are rigidly joined to the horizontal members 10 and 10 via the drift streak 2c.
The vertical frame members 3, 3 of the adjacent wall panels 1, 1 are integrated and function as a main pillar that firmly connects the upper and lower horizontal members 10, 10.

It should be noted that, instead of the joining means by the drift streak 2c, the joining by the stapling 12 shown in FIG. 1 was also examined, but the joining by the drift streak 2c is much more rigid than that by the stapling 12. In particular, it has been confirmed that the initial rigidity is excellent.

The structural face material 8 is composed of the horizontal members 10,
The upper and lower end portions are projected from the horizontal frame members 5 and 5 with respect to the hiccup surface 10a provided on the 10 side, and the inner surfaces of the horizontal frame members 5 and 5 are contacted with each other through fixing means such as nails. Frame 6
And contributes to the transmission of horizontal forces between the panel and the frame.

[0021]

As is apparent from the above embodiments, the bearing wall mounting structure according to the present invention has the following effects.

Since a plurality of factory-produced wall panels are mounted in parallel between the horizontal members of the frame structure to form the pillars and studs, the work efficiency is higher than that of the conventional construction method in which these are preliminarily installed on site. It is possible to shorten the construction period and reduce the cost.

Further, since the respective wall panels are connected to the horizontal member, the drift muscles are pressed into the dowel holes communicating with each other by fitting the tenon portions into the mortise holes, so that they are rigidly connected to each other. And resistance to vertical loads and transmission to vertical loads are improved resulting in a connection with a particularly high initial stiffness compared to nails or other connection means.
