Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing an outer wall panel used for an outer wall of a building.

[0002]

2. Description of the Related Art Conventionally, as a method of manufacturing an outer wall panel using a concrete material, there is known a method of manufacturing a reinforced concrete panel by pouring the concrete material into a formwork in which reinforcing bars and steel frames are arranged.

As another method of manufacturing an outer wall panel, a method of manufacturing a panel by a steel stud frame method is known in which a concrete panel and a steel frame are connected by an anchor bar or insert nut.

In addition, instead of arranging reinforcing bars or steel frames in the mold, a method of manufacturing a panel having a modified cross-section with a reduced weight by making the cross-section of the panel rib-shaped and waffle-shaped to increase the cross-section coefficient, and extrusion. A method of manufacturing a hollow panel by molding is known.

[0005]

However, in the case of a reinforced concrete panel, since the substantially entire panel is composed of the concrete material itself, there is a disadvantage that the heat insulation is poor. In addition, in order to deal with rusting of reinforcing bars,
Since it is necessary to increase the cover thickness and apply anticorrosive coating to the reinforcing bars, as well as assembling the reinforcing bars and setting them on the formwork, the manufacturing process becomes complicated and the material cost and manufacturing cost increase. Cause Furthermore, if the panel is made thicker, it becomes heavier unless the concrete itself is made lighter.If the weight of the concrete is made lighter, the outer wall surface becomes porous and a dense surface cannot be obtained, which may cause chipping or water permeability. .

Further, in the case of the panel manufactured by the steel stud frame method, the steel frame is used, which causes a problem of high cost. In addition, if the plate material is not attached to the inside of the room, it is vulnerable to a fire that occurs in the room. Furthermore, since the relatively thin concrete panel is simply connected to the steel frame, it is difficult to apply the dry method to the joint, and it is difficult to give a heavy outer wall impression.

Further, in the case of a panel having an irregular cross-section, a mold is required to have a male shape or a female shape, which causes a problem that the manufacturing is troublesome. Also, it is necessary to change the rib shape etc. according to the size of the panel to adjust the section modulus.
This causes inconvenience that it becomes difficult to support the product type.

Further, in the case of the hollow panel, there is a disadvantage that a large strain is apt to occur during molding and curing.

The present invention has been made in view of the above circumstances, and provides a manufacturing method for easily and easily manufacturing an outer wall panel that is lightweight, has excellent heat insulating properties, and is easy to dry joint joints at a low cost. It is an object.

[0010]

According to the method of manufacturing an outer wall panel of the present invention for solving the above-mentioned problems, a fixing metal fitting having a substantially cylindrical insert nut is sandwiched and fixed to the outer peripheral edge of a plate-shaped heat insulating material. , By fastening bolts to this insert nut, the fixing metal fittings and the plate-shaped heat insulating material are suspended in the formwork in which the concrete material of the surface layer part is poured, and the concrete material is further poured into the formwork to form the plate shape. This is a mold that is cured after being covered with a heat insulating material and a fixing metal fitting, and then removed from the mold.

[0011]

According to the present invention, there can be obtained a panel in which the fixing metal fitting and the plate-shaped heat insulating material are covered with the concrete material while leaving the nut holes on the surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the manufacturing process of the outer wall panel 1, and FIGS. 2 and 3 show the outline of the overall construction of the outer wall panel 1.

That is, according to the method of manufacturing the outer wall panel 1, the fixing metal fitting 3 having the insert nut 31 is sandwiched and fixed to the corner of the plate-shaped heat insulating material 2, and the bolt 7 is fastened to the insert nut 31. , The fixing bracket 3
And the plate-shaped heat insulating material 2 was suspended in the mold 5 into which the concrete material 4 of the surface layer portion was poured, and the concrete material 4 was further poured into the mold 5 to cover the plate-shaped heat insulating material 2 and the fixing metal fitting 3. After curing in the state, the mold is removed.

Examples of the plate-shaped heat insulating material 2 include organic heat insulating materials such as polystyrene (polyvinylidene chloride) and phenol foam, and calcium silicate heat insulating boards, lightweight rock wool boards, and inorganic heat insulating materials such as foam concrete. Can be used. The thickness and size of the plate-shaped heat insulating material 2 are not particularly limited, and any appropriate material may be used as necessary. Further, unevenness may be provided on the surface of the plate-shaped heat insulating material 2 to improve the fixing property with the concrete material 4 coated on the surface of the plate-shaped heat insulating material 2.

As shown in FIG. 4, the fixing member 3 includes a plurality of reinforcing bars 33 attached to an insert nut 31 formed in a substantially cylindrical shape.
Are welded together. Then, as shown in FIG. 5, the corner portions of the plate-shaped heat insulating material 2 can be clamped and fixed by the reinforcing bars 33. Further, the reinforcing bars 331 welded in the vertical direction prevent the insert nut 31 and the plate-shaped heat insulating material 2 from coming into contact with each other. As a result, a sufficient amount of concrete material 4 that ensures a sufficient fixing property can be poured between the insert nut 31 and the plate-shaped heat insulating material 2. Also, insert nut 3
1 also has an appropriate rib 34 in the axial direction and the circumferential direction.
Is provided to improve the fixing property with the concrete material 4.

The fixing metal fittings 3 are designed to be clamped and fixed at four corners of the plate-shaped heat insulating material 2, but it is not particularly limited to being clamped and fixed only at the corners. ,
It may be provided at an appropriate position on the outer peripheral edge of the plate-shaped heat insulating material 2, if necessary.

The concrete material 4 is not particularly limited and, for example, cement, aggregate, water or the like premixed with highly durable reinforcing fiber such as glass fiber or carbon fiber may be used. it can.

Next, a method of manufacturing the outer wall panel 1 will be described.

As shown in FIG. 1, first, the concrete material 4 forming the surface portion of the outer wall panel 1 is poured into the mold 5.

Then, as shown in FIG.
The plate-shaped heat insulating material 2 attached with is suspended in the form 5.
This suspension is performed by fastening a bolt 7 to the insert nut 31 of the fixing metal fitting 3 via the hanging metal fitting 6 and locking the hanging metal fitting 6 to the formwork 5.

Then, the concrete material 4 is poured into the mold 5 to cover the plate-shaped heat insulating material 2 and the fixing metal fitting 3. Then, after curing as it is, the outer wall panel 1 is obtained by demolding.

The outer wall panel 1 constructed in this way
Is the nut hole 32 of the insert nut 31 during suspension.
Since the bolts 7 are fastened to the fixing metal fittings 3 and the plate-shaped heat insulating material 2 except the nut hole 32, the fixing material 3 and the plate-shaped heat insulating material 2 are entirely covered with the concrete material 4. Therefore, while the exterior material of the outer wall panel 1 has a solid image due to the concrete material 4, the outer wall panel 1 has a solid appearance.
It is light in weight and has an excellent heat insulating effect by the plate-shaped heat insulating material 2.

Further, the plate-shaped heat insulating material 2 to which the fixing metal fittings 3 are attached can be manufactured by a simple manufacturing process in which the concrete material 4 is poured into the formwork 5 by pouring, and thus the manufacturing cost is reduced, It is possible to easily support product types when manufacturing various outer wall panels 1. In addition, when pouring the concrete material 4 forming the surface portion of the outer wall panel 1 into the formwork 5, a finishing material (not shown) such as tiles may be laid in advance, so that these finishing materials can be preliminarily attached. it can.

Furthermore, since the outer wall panel 1 itself can obtain an excellent heat insulating effect and the entire surface can be made smooth, the panel surface on the indoor side can be used as the inner wall as it is in a construction state. . It can also be used as a floor panel or roof panel.

The outer wall panel 1 can be easily constructed by fastening the skeleton 8 and the outer wall panel 1 with the bolts 7 via the fixing fittings 9, as shown in FIG. Further, the outer wall panel 1 has ribs 1 on the upper side and the lower side by making the shape of the mold 5 into a desired shape.
1 and the groove 12 can be formed in the side portion, the gap between the outer wall panels 1 is determined by a so-called dry method such as open joint or double seal as shown in FIGS. 7 and 8. A joint shape is possible.

[0027]

As described above, according to the present invention, it is possible to obtain a panel in which the fixing metal fittings and the plate-shaped heat insulating material are covered with the concrete material while leaving the nut holes on the surface. Therefore, the plate-shaped heat insulating material inside the panel is obtained. This makes it possible to obtain excellent heat insulation. Further, since the concrete material is poured so as to cover the plate-shaped heat insulating material, the plate-shaped heat insulating material serves as a core material, and a panel without distortion can be formed. Further, since the concrete material covers only the plate-shaped heat insulating material, it is possible to obtain a lightweight panel in consideration of a heavy image.
