Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a composite panel in which a hardenable plastic material, such as concrete containing glass fibers, is layered on a metal panel.

In a metal composite panel used as an exterior material, a partition plate is attached to provide a margin at the cut end. If an external force is applied to this partition plate, there is a risk that the partition plate and the fiber-containing hardening plastic material may peel off due to the adhesion effect alone.

The present invention has been proposed in order to solve these problems, and involves rotatably attaching an anchor to a partition plate placed on the upper surface of the end of a metal panel, and rotating the anchor above the panel. In this state, a fiber-containing hardening plastic material was applied to the top surface of the same panel.
A method for manufacturing a composite panel, characterized in that the anchor is rotated downward before the plastic material has hardened, and then a fiber-containing curable plastic material is layered to a predetermined thickness on the plastic material layer. It is.

In the present invention, as described above, an anchor is rotatably attached to a partition plate placed on the upper surface of the end of the metal panel, and the anchor is rotatably attached to the partition plate placed on the upper surface of the end of the metal panel, and the anchor is attached before the fiber-containing hardening plastic material is layered on the upper surface of the metal panel. Then, the anchor is rotated upward, and in this state, the first fiber-containing hardening plastic material is applied to the upper surface of the metal panel. Since there are no obstacles, the application of the plastic material can be easily carried out.

In the present invention, the anchor is then rotated downward and held in a predetermined position before the fiber-containing curable plastic material deposited on the metal panel hardens, and the fibers are deposited on the plastic material to a predetermined thickness. Since the fiber-filled hardenable plastic material is layered, the anchors are anchored within the fiber-filled hardenable plastic material layer on the metal panel, and the partition plate is firmly fixed to the same layer via the anchors. There is no risk of it peeling off from the panel. Furthermore, when applying an additional layer of the fiber-containing curable plastic material, the work can be carried out smoothly since there are no obstacles. Furthermore, since the anchor is rotatably attached to the partition plate in advance, the anchor position can be accurately determined, and as mentioned above, the fiber-containing hardening plastic material can be layered smoothly without being disturbed by the anchor. Therefore, the present invention has many advantages, such as being able to accurately control the coating thickness of the plastic material.

The present invention will be described below with reference to the illustrated embodiments.

Reference numeral 1 denotes a metal panel made of aluminum, stainless steel, etc., which is relatively thin and has a thickness of 0.5 mm to 1.5 mm, fixed on a surface plate, and a partition plate 2 is provided at the end of the metal panel. A recessed groove 2a is formed in the partition plate 2 in its longitudinal direction, and vertical bent pieces 2b and 2c extend from the free edges of the upper and lower horizontal parts of the recessed groove 2a.

An anchor receiver 3 having an L-shaped planar shape is provided in the groove 2a.
is slidably fitted therein, and an anchor 4 is rotatably pivoted to the vertical main piece 3a via a pin 5. The anchor 4 is composed of a square piece 4a pivotally attached to the main piece 3a, and a horizontal piece 4b connected to the tip of the main piece 4a perpendicularly thereto. and a tip hook portion 4d.

When manufacturing a composite panel, the anchor receiver 3 is slid along the groove 2a of the partition plate 2 to a desired position, and as shown in FIG.
The anchor receiver 3 is fixed by striking the vertical bent pieces 2b, 2c into a notch 3c provided in a part of the bent piece 3b perpendicular to the vertical main piece 3a to engage the pieces. (See FIG. 4) On the other hand, an adhesive 6 such as an epoxy resin adhesive is applied to the upper surface of the metal panel 1. (See FIG. 1) Next, as shown in FIG. 2, the anchor 4 is rotated upward to connect the upper surface of the metal panel 1 and the partition plate 2.
A first fiber-containing hardening plastic material 7A made of glass fiber-containing concrete or the like is sprayed to a predetermined thickness t ₁ over the inner surface of the container.

Rotate the anchor 4 downward before the hardening plastic material 7A is hardened so that the horizontal piece 7b is seated or buried in the plastic material 7A,
A fiber-containing hardening plastic material 7B made of the same glass fiber-containing concrete as the plastic material 7A is sprayed onto the plastic material 7A to a predetermined thickness _t2 .
(See Fig. 3) At this time, each of the plastic materials 7 is
Although A and 7B are integrated, the through hole 4c and the hook portion 4d may be omitted depending on the case.

As described above, according to the present method, there are no obstacles when layering the fiber-containing hardening plastic material on the metal plate 1 and the partition plate 2, so the work can be carried out smoothly, and the position of the anchor 4 and It has the advantage that the coating thickness of the fiber-containing curable plastic material can be made accurate.
