Reference numeral 3 is a wall body that is attached from the base portion to the lower part of the window.
The width of the wall is half-width or one-width because it is suitable for wooden construction.

FIG. 1A shows a rigid frame body provided on the inner wall side of the wall body. The frame angle 1 is assembled by using an angle member of about 20 × 20 × 3, and the upper and lower four parts of the frame body are assembled. The even portion is composed of a reinforcing plate 2 in which 30 × 3 flat plates are attached in a staggered shape, and prevents deformation of the frame angle 1. In this frame angle 1, a 0.4 mm thick steel plate 4 provided with openings and projections on a flat plate is arranged and welded to a 22 × 1.5 reinforcing plate 3 and the frame angle 1 and the reinforcing plate 2 are arranged.
They are also welded together to form the inner wall body frame structure shown in FIG. A zinc screw is attached to the frame angle 1 so that the pillar, the wall and the frame can be connected to each other.

FIG. 1 (B) shows a net body provided on the outer wall side of the wall body, and a lath net 5 defined in JIS No. 2 for preventing the outer wall material from falling is reinforced in the lateral direction by bending both ends by 50 to 80 mm. The material 6 and the longitudinal reinforcing material 7 are welded. This outer wall side net body and the above-mentioned inner wall side rigid body are combined and welded,
As shown in (C), the upper wall body 21, the intermediate wall body 22,
The lower wall 23 is made into a cage, and the space of both side walls thereof has a urethane foam 8 having a thickness of 50 to 80 mm as a heat insulating material.
Place. Figure 1 shows the situation of the cage constructed in this way.
The cross-sectional view is shown in (D).

On the surface plate 10, a design sheet 9 having a design for decorating the outer wall of the wall is placed, and the design is directly transferred to the outer wall portion of the lightweight cement board inside / outside integrated wall material, It is designed to be used as an outer wall material. On this pattern sheet 9, an outer wall side frame 11 having a partition plate for manufacturing the upper wall body 21, the intermediate wall body 22, and the lower wall body 23 is placed, and the respective cages are placed in the partition plate. Place your body,
The mixed aggregate that constitutes the external wall material is placed.

The outer wall side mixed aggregate is, by weight part, 74.2% of Portland cement, 7.4% of micro silica,
14.0% of shirasu balloon, 1.7% of glass fiber, 2.5% of sand, 95% of water and 5% of a polycarboxylic acid ether-based water reducing agent are evenly mixed to form an outer wall aggregate of 20 mm.
Cast thickly. At the time of driving, as shown in FIG. 3, the lath net 5 of the basket is adjusted so as to be positioned at the central portion of the outer wall mixed aggregate which is driven to a thickness of 20 mm. At the time of driving, the mixed aggregate is vibrated by using a vibrator or the like to release the bubbles and the like at the time of driving the aggregate so as to be homogeneously integrated, and the cage and the mixed aggregate are brought into close contact with each other.

After the outer wall side mixed aggregate is cast, a similar inner wall side formwork 12 is placed as shown in FIG. 3, and the inner wall side mixed aggregate is cast in the same manner as the outer wall side mixed aggregate. To do. Inner wall side mixed aggregate is Portland cement 46.7%, Mike silica 4.5%, Fuyolite 40.2%, Shirasu balloon 4.2%, glass fiber 2.0%, water 95% and water reducing agent 5
% Aggregate liquid is mixed and 2.4% is mixed, and the aggregate is cast in a thickness of 25 mm.

After placing the mixed aggregate on the inner and outer walls, 20 to 3
After drying at room temperature of 0 ° C. for about 8 hours or more, aging is performed for about 20 days or more in a natural environment to remove strain. If this aging step is omitted, when used as a load bearing wall in a frame construction method, the wall body is distorted and the utility value as a building is reduced. As mentioned above, the mixed aggregates are all made of lightweight aggregates such as shirasu that carry closed cells, and glass fibers are used to prevent cracks. A lightweight wall with a finish is completed.

Since the lightweight cement inner / outer integral wall material constructed as described above uses a lightweight material such as urethane foam as a heat insulating material, the apparent specific gravity of the half-width wall body is as light as 0.9, Since the inner wall side steel body in which the frame angle of 20 × 20 × 3 and the reinforcing plate are welded is used for the flat plate steel sheet having the openings and protrusions in the galvanic steel sheet of 4 mm thickness, the allowable shear strength is also 1076 Kgf / m. The high bearing wall of As a result, the striations required by the conventional method were eliminated.

FIG. 4 shows an embodiment of a concrete wall / large wall construction method in which the lightweight cement inner / outer integrated wall material manufactured by the above-mentioned manufacturing method is used as a wall body for an actual wooden house. After completion of the framing, the lightweight cement internal / external integrated mass material according to the present invention is attached to the pillar 1
3, fit between the body 16 and the base 17, and assemble in the order of the lower wall body 23, the intermediate wall body 22, and the upper wall body 21 at the zinc screw insertion position provided in the frame angle 1.
The pillars, the glove, the base, and the upper, middle, and lower walls are fixed together by fixing them. Conventionally, framing was required to assemble the wall body, but since this wall body has a high axial magnification of 5.0, the rigidity of the wall body exhibits vibration resistance even if the framing is omitted. , I no longer need it. After the wall is attached, the interior surface on the inner wall side is finished with a decorative material, the outer wall portion is finished with a caulking 15 for waterproofing, and the corner portions of the pillars cover the outer wall with corner corners 14. .

[Effects of the Invention] As described in detail above as examples, the lightweight cement inner / outer integrated wall material according to the present invention is
It uses urethane foam as a heat insulating material, is composed of lightweight aggregates with closed cells, and uses glass fiber to prevent cracks. It has excellent light weight, fire resistance, heat resistance, and angle frame, reinforcing plate, reinforcing material, and steel plate. Since the strength is strengthened by the method, the framing magnification is as high as 5.0, which eliminates the need for the striations required by the conventional method. Since urethane foam is used as the heat insulating material, it has an apparent specific gravity of 0.9, is easy to handle, has excellent workability, and can be expected to reduce construction costs, and it is a lightweight aggregate and urethane with closed cells. Since a foam is used, it has many advantages such as high heat insulation and no condensation.
