Description

TECHNICAL FIELD The present invention relates to a gate-shaped load bearing wall, and more particularly to a load bearing wall suitable for use in a building with a large space.

<Problems to be Solved by the Invention> When constructing a building space with a large span in the related art, a separate beam member is erected on a load bearing wall that has been erected in advance as a building frame, and both are mounted via bolts, nails, etc. Were joined together. Therefore, as the span increases, the height of the beam member naturally increases, and the joint strength at the joint must be increased, which makes the joint construction on site large and complicated.

<Means for Solving the Problems> The present invention has been made in view of the above problems, and a column base member that is substantially composed of a sleeve portion, an upper portion thereof, and a cantilever portion is made to face the cantilever portion. In a state in which the beam members are installed between the cantilever beam portions in the closed state, the column base members fix the substantially frame members to both sides of the substantially inner plywood, In the beam holding part, a substantially outer plywood is attached with a part of the tip side of the frame exposed, and the beam members fix the outer frame to both sides of the rectangular inner plywood. An outer plywood is attached to both ends of the beam member with part of the frame member exposed, and the exposed frame member of the cantilever portion and the exposed frame member of the beam member. The column base member and the beam member are formed in a gate shape by attaching a gusset plywood to and.

<Operation> The column base member and the beam member have a so-called composite column structure and composite beam structure in which the inner plywood, the frame member and the outer plywood are integrally assembled.
The column base member is a combination of a sleeve portion and a cantilever portion.
In addition, these column base members and beam members are joined by gluing plywood gusset over each cantilever beam member and beam member, and the joining strength of both members is more than that of butt joints. ,
Has a large yield strength. Therefore, the column base member and the beam member integrally bear the horizontal force and the vertical force, and a large span structure can be obtained without increasing the beam back.

<Example> A gate-shaped bearing wall of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of the gate-shaped load bearing wall w, and FIG. 2 is a plan view of the same. This gate-shaped load bearing wall w is a pair of column base members 1,1
The beam member 2 is installed between them. That is, the cantilever portion of the column base member 1 is made to face each other, and the both end portions of the cantilever portion and the beam member 2 are joined. Figure 3 shows
FIG. 3 is an exploded perspective view showing the structure of the column base member 1. The column base member 1 is attached with each member on both sides of the inner plywood 11. That is, both sides 11a, 11b of the inner plywood 11 that is substantially shaped
The frame members 12 and 13 which are respectively made up of are fixed. Frame material 12,13
Is a wooden rod-shaped material, such as rafters, half-divided materials, etc., assembled as vertical and horizontal materials. Further, outer plywoods 14 and 15 are attached to the outer surface sides of these frame members 12 and 13. The outer plywoods 14 and 15 are formed such that the horizontal portions 14a and 15a thereof are shorter than the inner plywood 11 in length. As a result, the respective members are formed into an integral plate-shaped member as shown in the side view of FIG. 4 and the plan view of FIG. That is, it is a substantially plate-shaped material including the sleeve portion 1A and the cantilever portion 1B. In this cantilever portion 1B, the lengths of the horizontal portions 14a, 15a of the outer plywood 14, 15 are formed to be shorter than the same length of the inner plywood 11, as described above. As shown, parts of the frame members 12 and 13 are exposed, and beam-attached surfaces 16 and 17 are formed on both surfaces.

FIG. 6 is an exploded perspective view showing the structure of the beam member 2. This beam member 2 has frame members 22 and 23 having substantially the same outer shape fixed to both surfaces 21a and 21b of a rectangular inner plywood 21, respectively. Paste 25. Outer plywood 2
As shown in the front view of FIG. 7, 4, 25 are formed to be shorter than the inner plywood 21, 21. Therefore, as shown in the plan view of FIG. 8, the frame members 22, 23 are exposed at both ends of the beam member 2, and the attachment surfaces 26, 27, 28, 29 are formed at both ends of the beam member 3, respectively. The column base member 1 and the beam member 2 have the same thickness,
Moreover, the height of the cantilever beam portion 1B and the beam back of the beam member 2 are formed to be substantially equal. Further, fixing and pasting of each member is performed by using a nail, a dowel, an adhesive or the like. A screw nail is used as the nail, and a water-based vinyl urethane adhesive is used as the adhesive.

Next, a case where a gate-shaped load bearing wall w is formed by using the column base member 1 and the beam member 2 having the above-described configuration will be described. As shown in FIG. 1, first, a pair of column base members 1, 1 are attached to their cantilever portions 1B,
Place 1B facing each other. Normally, the distance between the cantilever portions 1B, 1B is substantially equal to the length of the beam member 2 corresponding to the span of the building. In both of the cantilever portions 1B, 1B, as shown in the X portion of FIG. 2, the sticking surface 16 of the column base member 1 and the sticking surface 26 of the beam member 2 are in the same plane, and the sticking surface 17, 27 also forms the same plane. Gusset plywood 3, 3 is attached to each of the attachment surfaces 16, 26 and 17, 27. It is usually attached by using a screw needle and an adhesive together.

Similarly, the gusset plywood 3, 3 is also attached to the same planar attachment surface (16 28, 17 29) formed by the other column base member 1 and beam member 2. As a result, the column base members 1 and 1 and the beam members 2
Is an integrally joined gate shape, and the rigidity of the column base members 1 and 1 and the beam member 2 itself, and the joints between them are also high, so that they can sufficiently oppose horizontal and vertical forces. Become.

The column base member 1 and the beam member 2 may be pre-structured, and the gusset plywood 3 may be attached on site, and the length of the beam member 2 is appropriately selected according to the span of the building.

<Effects of the Invention> In the gate-shaped load bearing wall as described above, the column base member is integrally formed with the sleeve portion and the cantilever beam portion, and even when the beam member is joined, the sticking surface of both members is attached. On the other hand, since the gusset plywood is attached, the column base member and the beam member form a highly synthetic gate type. In addition, since the span of the beam member can be changed by changing the length of the beam member itself, the bearing wall has a wide range of application.

Moreover, the column base member and the beam member are separately synthesized and carried into the site, and the gusset plywood is attached on the site, and the length is sufficient, which is excellent in construction.
