Abstract

PURPOSE:To prevent the generation of stress in a honeycomb panel by uniformizing the temp. distribution of the panel at the times of day and nightfall by arranging sections to the end parts of the honeycomb panel and densely forming the honeycomb cells of a honeycomb core adjacent to the sections. CONSTITUTION:A honeycomb core 1 is formed by forming adhesive coated parts to short strip like thin aluminum plates at a predetermined intervals and laminating the thin plates in a zigzag pattern to partially bond them and stretching the bonded plate in the laminating direction to expand parts other than the adhesive coated parts into a hexagonal shape. In order to densely form honeycomb cells of the honeycomb core 1 at the parts adjacent to sections 3, a method lowering the expansion ratio of the end parts 6 of the heneycomb core 1 and a method reducing the unevenness of the corrugations of the corrugated thin plates arranged to the end parts 6 of the honeycomb core 1 are adapted. The honeycomb panel composed of the honeycomb core 1 having end parts 6 where honeycomb cells are densely formed as compared with the central part 5 of the honeycomb core 1 can be produced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a honeycomb panel, and more particularly to a honeycomb panel suitable as a member constituting an outer wall of a building such as a curtain wall.

[0002]

2. Description of the Related Art A honeycomb panel is a member constructed by joining face plates 2 to upper and lower surfaces of a honeycomb core 1 as shown in FIG. 4, and is widely used as a building material. As the material of the honeycomb core and the face plate, an aluminum plate, an aluminum foil, a plastic sheet, paper or the like is used. In addition to adhesion in the case of a metal material, an adhesive agent in the case of brazing or soldering or a non-metal material Are joined and integrated by.

When it is used as a member constituting an outer wall of a building, the profile 3 is joined to the end of the honeycomb panel, and the panels are joined to each other and the other members through the profile 3.

[0004]

However, when the outer wall of a building is constructed by the above honeycomb panel, the panel warmed by solar heat in the daytime warms the center part earlier than the end part, and the center part ends at the nightfall. Cools faster.
For example, FIG. 5 shows the temperature distribution of each part of the BB cross section of FIG. 4 at nightfall. Therefore, there is a problem in that the honeycomb panel expands and contracts, stress is applied to the end portion 3 and the panel joint portion 4, and the shape member and the panel are separated.

The object of the present invention is to solve the above problems,
It is an object of the present invention to provide a honeycomb panel in which the temperature distribution of the panel is made uniform during the daytime and at nightfall so that stress is not generated when used for the outer wall of the building.

[0006]

To achieve the above object, a honeycomb panel according to the present invention has a honeycomb panel formed by joining face plates to both sides of the honeycomb panel, and a shape member is provided at the end of the honeycomb panel. The honeycomb core adjacent to the material is densely formed.

When a honeycomb panel having a shape member at its end is connected through the shape member to form an outer wall of a building, the heat capacity of the shape member is larger than that of the honeycomb core, so that it is heated by solar heat. The heating rate of the profile is slower than that of the honeycomb core, and the cooling rate of the profile is slower than that of the honeycomb core when the temperature at sunset is low.As a result, the temperature difference between the profile and the honeycomb core results in a honeycomb panel. Expansion and contraction occur in the joint and stress is applied to the joint between the shape member and the panel, causing peeling. According to the present invention, by closely forming the honeycomb of the honeycomb core in the portion adjacent to the shape member, the heat capacity of the portion is made close to the heat capacity of the shape member and the temperature difference is eliminated.

There are two methods for making the honeycomb core. One of them is, for example, after forming an adhesive application part on a strip-shaped aluminum thin plate at a predetermined interval and laminating these thin plates so that the adhesive application part is staggered, and then partially adhering them. , And is expanded in the stacking direction to expand the portion other than the adhesive application portion into a hexagonal shape. Another method is to join parallel parts of thin plates that have been previously processed into a corrugated shape.

In order to densely form the honeycomb of the honeycomb core in the portion adjacent to the shape member, the expansion rate of the end portion of the honeycomb core is reduced, and the corrugated thin plate corrugate disposed at the end portion of the honeycomb core is formed. 1 and 2, a honeycomb panel made of a honeycomb core having an end portion 6 in which the honeycomb is denser than the central portion 5 of the honeycomb core 1 is manufactured as shown in FIGS. 1 and 2. can do.

[0010]

According to the structure of the honeycomb panel of the present invention, the honeycomb of the honeycomb core adjacent to the profile arranged at the end of the honeycomb panel is densely formed, and the honeycomb formed portion is densely formed. Since the heat capacity of the core becomes large, the heating / cooling speed of that part approaches the heating / cooling speed of the profile, and the temperature difference near the edge of the honeycomb panel becomes small, resulting in no difference in expansion / contraction of the honeycomb panel. The problem that stress is applied to the joint between the panel and the panel is solved.

[0011]

EXAMPLES Examples of the present invention will be described below. The honeycomb panel of the present invention shown in FIG. 1 was produced by the spreading method, and the face plate and the profile were attached by adhesion. Table 1 shows the material and dimensions of the completed honeycomb panel.

[0012]

[Table 1]

The hakam panel of FIG. 1 manufactured according to the dimensions and materials shown in Table 1 was exposed to solar heat, and the temperature distribution during cooling in the AA cross section of FIG. 1 was measured. The results are as shown in Fig. 3, and it was confirmed that the temperature difference near the edge of the honeycomb panel was small. No peeling between the panel and the profile was observed even after the 1-year exposure test.

[0014]

As described above, in the honeycomb panel of the present invention, the temperature difference between the panels during use becomes small, and peeling of the panel and the profile is prevented.
