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 for manufacturing an outer wall panel using a concrete material, there has been known a method of manufacturing a reinforced concrete panel by pouring a concrete material into a formwork on 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 in which a concrete panel and a steel frame are connected by an anchor bar or an insert nut is known.

In addition, instead of arranging a reinforcing bar or a steel frame on a mold, a method of manufacturing a panel having a modified cross-sectional shape with a lighter weight by increasing the cross-sectional modulus by making the panel cross-section into a rib shape and a waffle shape, and an extrusion method. A method of manufacturing a hollow panel by molding and the like are known.

[0005]

However, in the case of a reinforced concrete panel, since substantially the entire panel is made of the concrete material itself, there is a problem that heat insulation is poor. In addition, in order to deal with the occurrence of rust on rebar,
In addition to the need to increase the cover thickness and apply rust-proof coating to the reinforcing bars, the need to assemble the reinforcing bars and set them on the formwork complicates the manufacturing process and increases the material and manufacturing costs. Is generated. Furthermore, when the thickness of the panel is increased, the concrete itself becomes heavier unless the weight of the concrete itself is reduced, and when the weight of the concrete is reduced, 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 a panel using a steel stud frame method, there is an inconvenience that the cost is increased because a steel frame is used. Further, unless a plate material is stuck on the indoor side, there is an inconvenience of being vulnerable to indoor fire. Furthermore, since the relatively thin concrete panel is merely connected to the steel frame, it is difficult to convert the joint to a dry method, and it is difficult to give the impression of a heavy outer wall.

Furthermore, in the case of a panel having an irregular cross-section, a male or female form is required for the formwork, which causes an inconvenience that the manufacturing is complicated. Also, it is necessary to adjust the section modulus by changing the rib shape etc. according to the size of the panel,
Inconveniences such as difficulty in dealing with varieties arise.

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

SUMMARY OF THE INVENTION 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 which is lightweight, has excellent heat insulation properties, and is easy to dry-joint joints at a low cost. It is an object.

[0010]

According to the present invention, there is provided a method of manufacturing an outer wall panel, comprising: fixing an outer peripheral edge of a plate-like heat insulating material to a substantially cylindrical insert nut;
The fixing bracket and the plate-shaped heat insulating material are suspended in a form frame into which the concrete material of the surface layer has been poured, and the concrete material is further poured into the form form. After curing in a state of pouring and covering the plate-shaped heat insulating material and the fixing bracket,
It is something that comes off.

[0011]

According to the present invention, it is possible to obtain a panel in which a fixing metal and a plate-like heat insulating material are covered with a concrete material while leaving a nut hole on the surface.

[0012]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a manufacturing process of the outer wall panel 1, and FIGS. 2 and 3 schematically show the entire structure of the outer wall panel 1.

[0014] That is, the production method of the outer wall panel 1, the corners of the plate-shaped heat insulator 2, by sandwiching fixed by fixing bracket 3 provided with the insert nut 31, to fasten the bolt 7 to the insert nut 31 The fixture 3 and the plate-like heat insulating material 2 are suspended from a mold 5 into which a concrete material 4 of a surface layer is poured, and the concrete material 4 is further poured into the form 5 so that the plate-like heat insulator 2 and the fixation metal 2 are fixed. After curing in a state where 3 is coated, the mold is released.

Examples of the plate-like heat insulating material 2 include organic heat insulating materials such as polystyrene (polyvinylidene chloride) and phenol foam, and inorganic heat insulating materials such as calcium silicate heat insulating plate, lightweight rock wool plate and foam concrete. Can be used. The thickness, size, and the like of the plate-like heat insulating material 2 are not particularly limited, and an appropriate material as needed is used. In addition, irregularities may be provided on the surface of the plate-like heat insulating material 2 to improve the fixability with the concrete material 4 that covers the surface of the plate-like heat insulating material 2.

As shown in FIG. 4, a plurality of reinforcing bars 33 are attached to an insert nut 31 formed in a substantially cylindrical shape.
Is constructed by welding. Then, as shown in FIG. 5, the corners of the plate-shaped heat insulating material 2 can be clamped and fixed by the reinforcing bar 33. Further, the reinforcing bar 331 welded in the vertical direction prevents the insert nut 31 and the plate-shaped heat insulating material 2 from coming into contact with each other. Thus, Lee <br/> between Nsa bets nut 31 and the plate-like heat insulator 2, and sufficient concrete material 4 only to ensure sufficient fixability adapted pourable. Also, insert nut 3
1 also has an appropriate rib 34 in the axial and circumferential directions.
Are provided, and the fixability with the concrete material 4 is improved.

The fixing bracket 3 is formed of a plate-shaped heat insulating material 4
Corner of placeToIt is designed to be clamped and fixed.

Position of the outer peripheral edge of the heat insulating material 2To pinch and fix
May be provided as needed.

The concrete material 4 is not particularly limited. For example, it is possible to use a material obtained by premixing a highly durable reinforcing fiber such as glass fiber or carbon fiber with cement, aggregate, water or the like. it can.

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

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

Next, as shown in FIG.
Is suspended in the mold 5.
This suspension is performed by fastening a bolt 7 to the insert nut 31 of the fixing bracket 3 via the suspension bracket 6 and locking the suspension bracket 6 to the mold 5.

Thereafter, the concrete material 4 is poured into the form 5 to cover the plate-like heat insulating material 2 and the fixing fitting 3. After curing as it is, the outer wall panel 1 is obtained by removing the mold.

The outer wall panel 1 thus constructed
Is the nut hole 32 of the insert nut 31 when suspended.
Since the bolt 7 is fastened to the fixing member 3, the whole of the fixing member 3 and the plate-like heat insulating material 2 except for the nut hole 32 are formed in a state covered with the concrete material 4. Therefore, the appearance of the outer wall panel 1 can be obtained as a solid image by the concrete material 4, while the outer wall panel 1
The heat insulating material itself is lightweight, and the excellent heat insulating effect of the plate heat insulating material 2 is obtained.

Further, since the plate-like heat insulating material 2 to which the fixing fittings 3 are attached can be manufactured by a simple manufacturing process of hanging the concrete material 4 by suspending it in the mold 5, the manufacturing cost can be reduced. A variety of types can be easily handled when manufacturing various outer wall panels 1. Further, when pouring the concrete material 4 constituting the surface portion of the outer wall panel 1 into the formwork 5, a finishing material such as a tile (not shown) is laid beforehand, so that these finishing materials can be pre-attached. it can.

Further, since the outer wall panel 1 itself can obtain an excellent heat insulating effect and the entire surface can be formed smoothly, the panel surface on the indoor side can be used as an inner wall in a construction state. . Further, it can be used as a floor panel or a roof panel.

The outer wall panel 1 can be easily installed by fastening the frame 8 and the outer wall panel 1 with bolts 7 via fixing brackets 9 as shown in FIG. The outer wall panel 1 is provided with ribs 1 on the upper side and the lower side by setting the shape of the mold 5 to a desired shape.
1 and the groove 12 can be formed in the side portion, so that the gap between the outer wall panels 1 is formed by a so-called dry construction method such as an open joint or a double seal as shown in FIGS. The joint shape becomes possible.

[0027]

As described above, according to the present invention, it is possible to obtain a panel in which the fixing bracket and the plate-like heat insulating material are covered with a concrete material while leaving a nut hole on the surface. Thereby, excellent heat insulating properties can be obtained. In addition, since the concrete material is poured so as to cover the plate-shaped heat insulating material, the plate-shaped heat insulating material functions as a core material, and a panel without distortion can be formed. Further, since the concrete material covers only the plate-like heat insulating material, a lightweight panel can be obtained in conjunction with a heavy image.
