Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a corner accessory used for a part of an outer wall corner of a building such as a house.

Generally, when constructing the outer wall of a house, a wall board material having a right-angled bend at a part of the corner is used, and this wall board material is called a corner accessory.

On the other hand, cement-based exterior wall materials are widely used as exterior wall materials for houses, but gold-based corner accessories and extruded cement-based accessories are used as corner accessories due to fire resistance, durability, etc. has been done.

However, since the gold maple corner accessory is not made of the same material as the inorganic exterior wall material, it gives a noticeable sense of incongruity and does not provide a luxurious appearance. In addition, in cement-based extrusion molding, a groove pattern can be formed in the same direction as the extrusion direction at the same time as molding.
If you try to form a groove pattern in the direction perpendicular to the extrusion direction,
The process is troublesome since it is necessary to process grooves in the irregularly shaped cross section after molding, and the apparatus has the disadvantage of being large in size and high in cost. Rurui is also made by joining two inorganic plates whose ends are cut at an angle of </s degree to form a cross-sectional shape, but this is time-consuming and does not have a high processing accuracy. If you don't have it, it will be a drawback.

Therefore, in view of these points, the present invention provides a method for manufacturing corner accessories that can mass-produce inorganic corner accessories with high accuracy.

An embodiment of the present invention will be explained with reference to the drawings. Fig. 1 shows a corner accessory (1) according to the present invention. First, a surface pressure undercoating sealer (3) is applied to an inorganic board (2). As the inorganic board (2), a cement-based material such as an asbestos cement silicate board is used. Further, as the undercoat 9 sealer (3), a urethane sealer or the like is used.

While the undercoat sealer (3) is still wet, a sheet material (4) is laminated on top of this coating layer. In addition to its original role as a sealer, this undercoat sealer (3) also serves as a temporary adhesive for sheet-like objects, so it must have appropriate adhesive properties, and can be used as appropriate by mixing an adhesive into the sealer. Make adjustments. The sheet-like material (4) is cloth;
Use paper etc.

Next, cut four V-grooves (5) parallel to each other on the iron surface of the inorganic plate (2) at specified positions until it reaches the sheet-like material (4) K on the surface side, being careful not to cut the sheet-like material (4). Delete it. Apply adhesive to this v# (5) and bend it at the V@ part to form a hollow column (6) with an opening-shaped cross section.
) are pressed together using a press to bond them together. After this,
The hollow column (6) is cut along the center line of the cross section perpendicular to the length direction of the hollow column (6) to divide it into four parts.
7).

After that, the sheet-like material (4) remaining on the surface of the cross-sectional member (7) is peeled off, and the sheet-like material (4) remaining on the surface of the cross-sectional member (7) is peeled off.
By applying top coat sealer (8) on the surface of
A corner accessory (1) according to the present invention is manufactured.

In order to form the lateral grooves (9) or the connecting notches (10) on the surface of the corner accessory according to the present invention, the inorganic plate (2) may be grooved in advance.

Moreover, when using it as a corner accessory for a large corner, a 7-color treatment or the like may be applied to the inner part of the corner accessory (1).

As described above, according to the present invention, the sheets are temporarily bonded using an inorganic sealer, and the sheets are peeled off after being cut and formed, and then a top coat sealer is applied, so that the surface treatment is sufficient and the effort of surface treatment is reduced. It can be omitted. Further, there are advantages such as mass production of corner accessories with high precision and ease of machining grooves for connection.

Claims (1)

[Claims] (1) Apply an undercoat sealer to the surface of the inorganic board, and while the sealer is still wet, layer a sheet-like material such as cloth on top and temporarily adhere it. A plurality of V-grooves reaching the sheet-like object are cut in parallel to each other, and adhesive is applied to the grooves and bent at the V-grooves to form a hollow column and bonded together.
The hollow column is divided into sections along the center line of the cross section to form a member having a cross-section shape, and then a sheet-like material on the surface of the member having a cross-section shape is peeled off and a top coating is applied to the surface. A method for manufacturing corner accessories.
