Description

  The present invention relates to a method for manufacturing a wall-like structure and a wall-like structure. More specifically, the present invention relates to a method of manufacturing a wall-like structure including a wall constituting the building and a wall around the periphery thereof, and the wall-like structure.

  In a wall-like structure constituted by using a gypsum board or an aluminum composite plate, a synthetic resin-based or gypsum-based coating material (prime coating material or top coating material) such as an epoxy resin is used for coating. However, since these coating materials are inferior in elasticity, cracks are easily generated by external forces such as vibration. Therefore, Patent Documents 1 and 2 have been proposed as techniques for preventing the occurrence of such cracks.

  In Patent Document 1, the occurrence of cracks is prevented by applying a primer to the entire surface of a wall-like structure configured using a gypsum board, and laying a net-like sheet on the primer. However, in order to lay down the net-like sheet on the entire surface of the wall-like structure, it is necessary to complete the shave before the primer is cured, which requires a lot of man-hours in a short time. The difficulty of work was high.

In Patent Document 2, an aluminum tape is applied to a joint portion of a wall-like structure configured using an aluminum composite plate and then applied, and the applied aluminum tape prevents cracks from occurring. However, if air enters between the aluminum tape and the aluminum composite plate, the aluminum tape peels off after the coating material is dried, resulting in cracks and the like.
For this reason, when trying to apply the aluminum tape accurately so that air does not enter between the aluminum tape and the aluminum composite plate, an accurate operation is required and the difficulty of the operation is high.

  As described above, there is room for further improvement in crack prevention of these wall-like structures.

As a material for the metal panel 1, it is preferable to use a lightweight material in order to enhance the collapse resistance due to an earthquake or the like, and in order to satisfy both strength and lightness, a light metal, particularly aluminum, is preferable. If the frame 11 is an aluminum extruded shape, it can be easily manufactured, can have an arbitrary cross-sectional shape, and can form the connecting portion 14 at the same time.
The outer plate 12 is preferably an aluminum plate or an aluminum composite plate (for example, a laminate in which a synthetic resin layer is laminated on an aluminum plate, or a synthetic resin layer provided between two aluminum plates). The aluminum material has both light weight and corrosion resistance.
The struts 20 can be made of various materials similar to those of the metal panel. However, in order to satisfy both strength and lightness, an extruded shape of a light metal, particularly aluminum, is preferable.

They are executed in order. Hereinafter, it demonstrates in order, referring also to FIG. 1 and FIG.

(Ground adjustment material application process)
First, as shown in FIG. 1, a base adjusting material 3 (referred to as an uncured coating material; the same applies hereinafter) is applied to the surfaces of the metal panels 1 and 1 and the support column 20 to apply a base adjusting material layer 3A (coating). A base adjusting material coating step is performed in which the material is hardened and solidified in a layered form (hereinafter the same). As shown in FIG. 2 (I), this operation is performed by glazing operation or roller application.
The base adjusting material layer 3A is applied with a thickness (about 0.2 mm) that allows the mesh sheet to be depressed.

  The base material 3 used in the production method of the present invention is a resin composition containing an epoxy resin and a silicone resin. The blending ratio of the epoxy resin and the silicone resin is preferably 25 to 41% by weight for the epoxy resin and 75 to 59% by weight for the silicone resin, and more preferably 30 to 34% by weight for the epoxy resin and 70 to 70% for the silicone resin. The most preferable blending ratio is 33% by weight for epoxy resin and 67% by weight for silicone resin.

  In the base conditioning material 3 of the present invention, since the blending ratio of the epoxy resin and the silicone resin is a blending ratio that provides sufficient elasticity, the cured material becomes a tough rubber-like elastic body after curing, and the adherend is expanded and contracted. Relieve stress. This property has the feature that external vibrations and shocks can be absorbed. For this reason, when this base material 3 is used, cracks and the like of the coating surfaces of the support columns 20 and the metal panels 1 and 1 can be effectively prevented.

(Mesh sheet lying down process)
The mesh sheet is applied to the joint between the metal panels 1 and 1 and the joint between the metal panel 1 and the support 20 until the base adjuster 3 is uncured and becomes a solid base adjuster layer 3A. The mesh sheet concealment process is performed. As shown in FIGS. 2 (II) to (III), the laying down is performed by placing the mesh sheet 2 on the uncured base conditioner 3 and pressing the mesh sheet 2 from above with a scissors or a roller. This is done by digging inside the layer 3A.

The mesh sheet 2 is obtained by crossing vinylon fibers into a net-like shape. Since the vinylon fibers have high tensile resistance, the mesh sheet 2 is also strong.
The mesh sheet 2 usually has a thickness of 0.10 mm to 0.16 mm, preferably 0.12 mm to 0.14 mm, most preferably 0.13 mm, and a width of 40 mm to 80 mm, preferably 50 mm. A thickness of ˜70 mm, most preferably 60 mm is used.

The top coating material application step for forming a solidified layer is performed. This operation is also carried out by a glazing operation or a roller coating operation as shown in FIG. 2 (IV).

  The top coat 4 can be arbitrarily selected from known ones, but typical ones include synthetic resin as a binder, sand and pulp as main components. Since this top coating material contains sand and pulp, it is characterized in that it has a natural texture and a bulky feeling. Further, a post-installed post box may be attached to the completed wall-like structure (panel wall), or surface coating may be applied for the purpose of design finishing.

  By executing the above steps, the wall-like structure of the first embodiment is completed.

Cracks on the surface can be effectively prevented.

(Mesh sheet lying down process)
Before the base preparation material 3 becomes an uncured and solidified base preparation material layer 3A, the mesh sheet is laid down on the base preparation material layer 3A in the vicinity of the joint 5a between the gypsum boards 5 and 5. The embedding process is executed. The sagging is performed by placing the mesh sheet 2 on the uncured base adjustment material 3 and pressing the mesh sheet 2 into the inside of the base adjustment material layer 3A by pressing it from above with a scissors or a roller.

Similar to the first embodiment, the mesh sheet 2 is made by crossing vinylon fibers into a net-like shape. Since the vinylon fibers have high tensile resistance, the mesh sheet 2 is also strong.
And when the foundation | substrate adjustment material 3 hardens | cures, the mesh sheet 2 will work | function as a reinforcing material and the intensity | strength of the foundation | substrate adjustment material layer 3A can be made high.

(Coating material application process)
Next, as shown in FIG. 3, a top coating material coating step is performed in which the top coating material 4 is applied to the upper surface of the base adjustment material layer 3 </ b> A to form the top coating material layer 4 </ b> A. This operation is carried out by a glazing operation or a roller coating operation. As the top coating material 4, it can be arbitrarily selected from known materials as in the first embodiment.
By executing the above steps, the wall-like structure of the second embodiment is completed.

The manufacturing method of the wall-like structure according to the present invention described above has the following effects.
Since the ground adjustment material contains a silicone resin and has elasticity, the ground conditioning material layer after construction also has elasticity, and cracks and the like are less likely to occur even when vibration is applied from the outside. In addition, since the mesh sheet only needs to be depressed at the joint portion, the work becomes easier as compared with the conventional example in which the mesh sheet is depressed all over.

(Wall-like structure)
By the above manufacturing methods, a wall-like structure having the following configuration is obtained.
The wall-like structure shown in FIG. 1 and FIG. 3 is configured by wall constituent members (metal panels, gypsum boards, columns, etc.) arranged adjacent to each other. Such a wall-shaped structure is composed of a base adjusting material layer 3A formed on the surface thereof, a mesh sheet 2 buried in the base adjusting material layer 3A, and a top coating layer formed on the upper surface of the base adjusting material layer 3A. 4A, and the base adjusting material layer 3A is formed by applying the base adjusting material 3 containing an epoxy resin and a silicone resin.

In the wall-like structure, since the base adjusting material 3 contains a silicone resin having elasticity, the base adjusting material layer 3A in the wall-like structure after construction itself has elasticity and vibrates from the outside. Even if is added, cracks and the like are less likely to occur.
In addition, the base material 3 has advantages such as high adhesion to a metal surface such as aluminum, and the coating material is securely attached, so that peeling does not occur.
Furthermore, since the mesh sheet 2 uses vinylon fiber, it is strong and gives strong resistance to joint opening due to vibration. Further, since the base conditioning material 3 is directly bonded to the surface of the wall constituting member through the mesh sheet 2, there is an advantage that peeling of the coating layer is difficult to occur.
