Abstract

PURPOSE:To reinforce the strength of a wall surface by mounting a plywood for structure on the surface of a structural frame having upper and lower frame parts and upper and lower intermediate lateral frame parts to integrally form a U-shape or an I-shape. CONSTITUTION:Upper and lower frame parts 5 and 6 are disposed to the upper and lower parts of three longitudinal frame parts 4a, 4, and 4b disposed in parallel and nailed for joining. Upper and lower intermediate lateral frame parts 7 and 7 are disposed to form a structural frame 2, and a plywood 3 for structure is mounted on the surface of the frame 2 to form a bearing wall panel 1. The panels 1 are disposed in a manner to be positioned facing each other on both sides, and protruding wall parts 11 and 11 are directly or indirectly joined together through coupling members 12 and 13 for increasing a space. When a vertical load is exerted on the protruding wall parts 11 and 11 and bending is about to occur, the protruding wall parts press them against each other at a joining seam therebetween for support. This constitution improves surface rigidity and increases shape retention.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a frame wall construction method building, and particularly to a load-bearing wall panel for an opening frame in which fittings such as a sash are housed. [Prior art] When creating an opening in a load-bearing wall of a building using the framed wall construction method, the left and right ends of the lintel and window sill are brought into contact with the opposing sides of the left and right vertical frames at the side edges of the opening width, and the left and right ends of the vertical frame are While connecting by driving nails from the opposite side, at the middle position of the opening width, insert vertical bars at the top of the opening between the lintel and the upper frame of the load-bearing wall, and between the window sill and the lower frame of the same. The vertical load was supported by placing an appropriate number of frames under the opening according to the width of the opening. [Issue 8 to be solved by the invention] However, in such an opening, in particular, the vertical load applied to the lintel is prevented from being applied to the center of the width of the lintel due to the upper vertical frame of the opening disposed at the middle position of the width of the opening. In addition to this, the lintel tends to sag downwards around the center of its width (lintel sagging), and as a result, the joints connecting the left and right ends to the vertical frame tend to open upward. As a result, the nails at the left and right ends of the lintel tend to come loose, and the joint joints between the upper frame and left and right vertical frames of sashes and other fittings located near the joint joint also open upward, causing the screws to loosen. The structure is easily damaged due to the joints on the 1st floor, etc. These defects often lead to secondary failures such as poor opening/closing of fittings and water digging. Unhappened 11 was created in view of these problems, and is a frame-bonded wall 1-bi-method building that can significantly increase the strength of the wall around the opening, makes it difficult to deform the opening, and allows for masonry construction. The purpose of the present invention is to provide a load-bearing wall panel for an opening frame.

[Means for solving the problem] Kibatsu 1!1 is [completed in accordance with the purpose mentioned above, and the load-bearing wall around the opening is formed as a physical wall panel having a U-shape or an I-shape.] That is, the present invention has a plurality of vertical frame parts arranged in parallel, and a plurality of vertical frame parts disposed below the vertical frame parts and integrally protruding outward beyond the side end vertical frame parts. It consists of an l:f frame portion, and upper and lower intermediate horizontal frame portions that are arranged parallel to the upper f frame portion and integrally protrude from the inside of the side end vertical frame portion to the outside beyond this. 41.

This paper relates to a load-bearing wall panel for the opening frame of a building using the frame wall construction method, which is characterized by being integrated into the shape of a letter, and its gist is this. [Function] The upper and lower frame portions and the intermediate horizontal frame portion of the structural frame are integrally projected laterally beyond the side end vertical frame portions, and structural plywood is stretched over the surface of the structural frame to form a U-shape. Or, because it is integrated into an I-shape, this wall panel can handle the vertical load on the opening at the vertical height of the entire wall, just like the groove-shaped or ■-shaped panels that have integral flanges at the top and bottom of the web. The supporting protruding wall is formed seamlessly and integrally. In addition, two such load-bearing wall panels are arranged facing each other on the left and right, and the protruding wall portions of each are brought into contact with each other indirectly through an intermediate member for expanding the gap, or directly without intervening therebetween. If they are joined at least, an opening will be formed between both panels, and the joining seam between both panels will be located in the middle of the opening radius, and a vertical load will be applied to the protruding wall, causing the protruding wall to deflect. When this happens, the protruding walls of the left and right inner load-bearing wall panels press and support each other at the joining joint.

[Example] Hereinafter, the present invention will be further explained with reference to the drawings showing examples. First, 1 in Figs. The wall panel 1 has a structural plywood 3 stretched over the surface of the structural frame 2.

The structural frame 2 consists of three vertical frames FA arranged in parallel.
Upper and lower frame parts 5.6 are attached above and below 4a, 4, 4b, and are joined by nails (not shown) being driven into the wood ends, and parallel to the upper and lower frame parts - intermediate horizontal frame parts 7, 7 below. are arranged. In addition, each frame is 2 inches x 6 inches (actual size 3 inches).
4I lumber with a cross section of 8mm x 1401cm) was used. Here, the lower frame part 5.6 does not extend below the vertical frame part 12, but extends beyond the side edge of the opening 8 side and the vertical frame part 4a, respectively, and is integrally formed on the outside of these vertical frame parts. It stands out. In addition, the upper and lower intermediate horizontal frame portions are also connected to the side end vertical frame portion 4 on the opening 8 side.
It protrudes integrally from the inside of a beyond this. Incidentally, in order to allow the intermediate horizontal frame parts 7, 7 to protrude as one, the side end vertical frame part 4a is divided into three members. In addition, the middle horizontal frame parts 7, 7 and the side end vertical frame parts 4a are joined by diagonally driving nails (not shown), while the joints with the central vertical frame part 4 are joined by driving a nail from the plane of the vertical frame part. It has been done. Moreover, the upper and lower frame parts 5, 6 and the intermediate horizontal frame parts 7, 7 of the protruding part
A reinforcing material 9.9 with the same cross section was placed between them and joined by nailing. In this example, on the surface of the structural frame 2, 1
A 2 mm thick structural plywood 3 is attached to each frame portion 4, 4a, 4b, 5.
, 6.7 and the reinforcing material 9 with nails (io...) nailed and stretched, and the load-bearing wall panel l is attached to the vertically protruding wall portions 1 1 3.
1 and 1 are seamlessly formed and integrated into a U-shape with an opening 9 between them. The nailing pitch is approximately 100 ms to 150 ms at the peripheral edge of the plywood, and approximately 200 ms within the surface. Moreover, the height of the load-bearing wall panel l of this example is 2424 mm. The total width is 161
It is listed as 6 Peng. By the way, it goes without saying that such a load-bearing wall panel 1 for an opening frame can accommodate fittings only in its single opening 8, but in the wooden example, two identical load-bearing wall panels 1.1 are placed facing each other on the left and right. Along with the installation. Tr. By abutting and joining the protruding walls of the insulator, a wider opening is formed. 12.13 in Figure (A) is a connecting member for this connection, 12 of which is a continuous member that also serves as an intermediate member for increasing the distance between the left and right load-bearing wall panels, and the cross section is based on the 2 in x 6 in standard. Structural materials having a structure are framed in a small size, and plywood for A-building is stretched over the central spacing area. On the other hand, l
3 is a connecting member for direct attachment that also serves as such an intermediate member, and the above structural members are assembled into a small frame. These continuous Ayu members are inserted into the insertion portions l4... of the vertically projecting wall parts 1l... of the load-bearing wall panels 1.1 disposed on both the left and right sides of the load-bearing wall panels l, l. Nail the frames 5, 6, 7 and structural plywood 3 to join them. FIG. 2 shows a state in which the left and right load-bearing wall panels 1.1 are brought into contact and joined via the connecting member l2 which also serves as an intermediate member for expanding the distance. In addition, Fig. 3 shows a state in which such load-bearing wall panels l for opening frames are installed on the first and second floor walls of a three-story frame wall construction method building, and the load-bearing wall panels l for opening frames on the first floor are The wall panel l is erected on a foundation l6 which is placed on a cloth foundation l5, and on top of this is the load-bearing wall panel l for the opening frame on the second floor, which is then erected, and on top of that is a closed wall surface with no openings. The load-bearing wall panels 17 are stacked on top of each other. In addition, the adjacent upper and lower frames 5.6 (and upper stand 16) of each load-bearing wall panel 1, 1.17
) are joined by nailing (see joint seam 18.18). Also, the floor joists 19.19 are not placed between the upper and lower load-bearing wall panels, but rather are nailed to the vertical frame within the height of each load-bearing wall panel. In addition, 20.20 is the first floorboard placed perpendicularly between the joists, 21.21 is the floorboard stretched over the joists, 22 is the gassho, 23 is the roof joist, and 24 is the floorboard stretched over this L. With the installed floorboards, the inside of the roof shed can be used as a living room or for storage.

On the other hand, Fig. 4 and Fig. 5 show how the fittings fit into load-bearing wall panels 1.1 for opening frames arranged opposite to each other on the left and right.

In addition, its dimensions are approximately 2 4 2 4 mm in height.
, the total width is 1212mm in the same figure (A). (B) 2
It is 020m■. In addition, other points are the same as the first embodiment, so the same reference numerals are given in the figure and the explanation will be omitted. It is also possible to join other load-bearing wall panels for opening frames that are not shown in the drawings or of course have irregular shapes such as a U-shape and an I-shape. A rectangular wall panel for a closed K4 wall surface that does not form an opening may be placed adjacent to it.

In addition, one of the load-bearing wall panels for this U-shaped or ■-shaped opening frame
If you cut the protruding wall on the side at the site, you can store fittings that reach above the floor, such as doors and sweeping sashes.

Of course, each frame part of the structural frame has a cross section of 2 inX, for example.
4 in. 2 inX 8 in group? Various structural materials such as I can be used, and the thickness of the structural plywood is 9 mm.
．． 15-1 grade can also be adopted depending on the required strength.

Note that the heat insulating material in the illustrated load-bearing wall panel and the structural plywood on the back side may be filled and stretched in advance, for example, except for the joist hanging position.

In addition, the vertical and horizontal external shapes of the load-bearing wall panel, the dimensional relationship such as the protruding length of the upper frame and the intermediate horizontal frame from the side end vertical frame, or the intermediate horizontal frame 1 and 2 each below for reinforcement. The following L arrangement can be freely designed. As is clear from the above points, when carrying out the wood-spring repair 1, the specific shapes of the vertical frame portion, upper and lower frame portions, intermediate horizontal frame portions, structural frame, structural plywood, etc. may be changed, unless it contradicts the gist of the invention. , structure, dimensions, materials, number of members, arrangement, and relationships among these may change in various ways.

[Effects of the Invention] Since the present invention has a C configuration as described above, the surface of the structural frame in which the L frame portion and the intermediate horizontal frame portion are made to protrude sideways beyond the side end vertical frame portions. Structural plywood is attached to the wall and integrated into a U-shape or ■-shape, so the vertical load on the opening can be supported at the vertical height of the entire wall, just like the shape of channel steel or I-beam steel. The protruding wall part is seamlessly integrated and has extremely high surface rigidity, making it difficult for breakage or deformation to occur, especially at the side edges of the open part. In addition, if two such load-bearing wall panels are arranged facing each other on the left and right, and the protruding wall portions of the two panels are directly or indirectly abutted and joined to form an opening, the joining seam between the two panels can be formed. is located in the middle of the opening width, and when a vertical load is applied to the protruding wall and the protruding wall tries to deflect, the protruding walls of both the left and right load-bearing wall panels press against the tiles at the joint seam. Since the joints act to support each other, deformation is restricted by the phase pressure, and the surface rigidity around the opening is further increased, making it possible to improve the shape retention of the fittings.

Also, of course, as a result of attaching structural plywood to the structural frame and making it into panels, this load-bearing wall device can be constructed quickly. 11
First, since the inner height of the opening 11 has already been determined, even unskilled workers can easily form the load-bearing wall opening.
It is Qi.
