Description

[Detailed Description of the Invention] The present invention relates to a hollow laminate plate which is used as a material for construction, civil engineering, etc. and has a plurality of core tubes covered with an outer cover made of synthetic resin, rubber, etc.

The purpose of the present invention is to provide a hollow laminate plate that is resistant to drop impact, has excellent durability, allows the width of the plate material to be arbitrarily adjusted, and has greater strength.
. . . The outer periphery of the core tubes 2, 2 . At the same time as inserting it into the
A feature is that the cap material 1 is fixed to the outer cover 3.

The present invention will be explained in detail below based on embodiments shown in the drawings.

Figures 1 and 2 show the first embodiment, in which the outer periphery of two core tubes 2, 2 made of iron plates, aluminum plates, etc. formed into a predetermined shape is coated with synthetic resin, rubber, etc. An outer cover 3 consisting of the above is covered.

Both ends of the laminated plate material 4 thus constructed are formed into a single layer shape consisting only of the outer cover 3, while a head 5 that fits inside the end of the outer cover 3 and the two core tubes are formed. A cap material 1 having a pair of insertion portions 6, 6 that fit into the tubes 2, 2 is molded from a synthetic resin or a rubber material, and the insertion portions 6, 6 of the cap material 1 are inserted into the respective ends of the laminated tube 4. Insert into.

At the time of this insertion, an adhesive is applied to the outer periphery 7 of the cap material head 5 to adhere the cap material 1 to the outer cover 3.

Alternatively, the cap material 1 and the outer cover 3 may be molded from the same synthetic resin, and the same locations as the bonding portions may be thermally welded using high frequency.

Note that the cap body 1 is adjusted so that the end surface 3a of the outer cover 3 and the end surface 1a of the cap body 1 coincide with each other when the cap material 1 is inserted.
It is desirable to determine the axial length of the

In the above embodiment, the cap material 1 includes a pair of insertion portions 6,
6, however, it may be configured such that the cap bodies 1, 1 are inserted into the respective core tubes 2, 2 separately.

In the second embodiment shown in FIG. 3, a fitting protrusion 8 is formed on one side of the core tubes 2, 2.2, and a fitting groove 9 is formed on the other side. The core tubes 2, 2, 2 are connected and integrated, and an outer cover 3 is formed around the entire outer periphery to form a laminated plate material 4.

The cap material 1 may be inserted and fixed in the same manner as in the first embodiment.

The present invention can be configured in various ways other than those shown in the above embodiments.

For example, the number of core tubes 2 is not limited to that of the above embodiment.

As is clear from the above embodiment, in the present invention, the cap material 1 made of synthetic resin or rubber is fitted onto both ends of the plurality of core tubes 2, so that the cap material 1 is deformed even when an external force such as an impact when dropped is applied. can be prevented.

Also, since the cap material 1 is integrally fixed to the outer cover 3,
Due to the difference in thermal expansion, the core tubes 2, 2... and the outer shell 3
The peeling phenomenon can be prevented from occurring between the laminate and the laminate of the present invention, and even if the laminate of the present invention is handled a little roughly, the peeling can be prevented.

Furthermore, the cap material 1 can reliably prevent water and other foreign substances from entering the inside of the laminate of the present invention, and durability can be improved.

In addition, the present invention can be used for special purposes such as assembly boards that can float on the water surface, peripheral wall boards for heat insulation, etc., and because the outer periphery can be coated with synthetic resin in beautiful colors, it can be used as a beautiful building material, etc., and will not rust. It has the advantage of being lightweight and extremely easy to carry.

Furthermore, according to the present invention, by arbitrarily selecting the number of core tubes, a laminated plate material having a desired width can be easily formed. By bonding them together, they reinforce each other's strength, resulting in a laminated plate material with high strength as a whole.
