Specification hollow structure plate (9a) or a double-stage specification hollow structure plate in which a back layer (6) and a surface layer (8) are provided on the front and back of a corrugated core layer (5) to form an air layer (7) (9
b), a multi-layered honeycomb structure (A)
And the laminated honeycomb structure (A) is cut along a hot-cut line (10) as shown in FIG. 3 using a hot wire (Nichrome wire), a laser cut, a hot blade (ceramic) or the like. It comprises a honeycomb core material (11) made of a multilayer plastic, which is obtained by fusing and welding a honeycomb material.

As shown in FIG. 4, the integrally extruded hollow structure plate (9) or the corrugated type single-stage and double-stage hollow structure plates (9a) and (9b) have a longitudinal hollow structure as shown in FIG. Plate (12) and a hollow structure plate (1
3) The laminated honeycomb structure (A ′) may be formed by alternately laminating the directions.

[0008] A plastic material, a plywood, a metal plate or a board material made of plaster board or another material is provided on both the front and back surfaces of the multilayer plastic honeycomb core material (14) with a surface material (15) and a back material (16). May be bonded by heat pressing, high frequency welding, electromagnetic waves, or by using an adhesive.

Further, the diameter of the air layer of the honeycomb core material (11) of this multilayer plastic is 1 mm × 1
from 20 mm to 20 mm x 20 mm.
Small ones can be fixed with nails or screws.

Another embodiment of the present invention will be described with reference to the accompanying drawings. An air-filled structure plate made of plastic and having a plurality of air cushions provided with a plurality of air cushions and a back surface layer (2 '), or , An air-filled layer (17) provided with a plurality of surface layers (1 ') and air cushions, and a back layer (2')
A multi-layered plastic material characterized by obtaining a honeycomb material by laminating a large number of hollow structure plates made of the above, providing a laminated honeycomb structure as described above, and welding the laminated honeycomb structure by means of heat fusing. It is composed of a honeycomb core material.

[0011]

According to the present invention, an integrally extruded hollow structural plate (9) made of plastic or a corrugated type hollow structural plate (9a) (9b) of single-stage and double-stage specifications.
Are laminated, a laminated honeycomb structure (A) is provided, and the structure is welded by thermal fusing to obtain a honeycomb core material (11). The honeycomb core material is formed of intermediate air. The layer (4) having a small diameter has an excellent sound absorbing effect, is lightweight as a construction material, and can be fixed with nails or screws.

Further, as shown in FIG. 5, the front surface material (15) and the back surface material (1) were formed on both sides of the honeycomb core material (11) as shown in FIG.
By providing 6), warpage and bending strength can be further strengthened and used as concrete formwork panels, partitions, toilet booth panels, indoor partitioning materials, door materials, table materials, and other materials for vehicles and aircraft Can,
The air layer can be held independently by being lightweight and bonded.

Further, as shown in FIG. 6, a honeycomb core material composed of an air wrapping layer (17) serving as an air cushion and a back layer (2 '), or a wrapping material serving as a surface material (1') and an air cushion. By providing the gas layer (17) back material (2 '), a more robust and heat insulating multilayer plastic honeycomb core material can be obtained.

Further, by making it into an independent panel, it can be used for a material that utilizes the pressure resistance, durability and heat insulating effect. It can be used for marine fields such as pontoons and floats using an independent air layer. It is environmentally friendly and can be recycled because it can be heat welded by heat without using any.

Further, as shown in FIG. 4, the degree of air conditioning or water flow is changed by providing a laminated honeycomb structure (A) by thermally fusing and welding each hollow structure plate in the vertical and horizontal directions. These materials are made of plastic and can be used in humid places, in soil or under water because they are made of plastic. It has an extremely beneficial effect, such as obtaining a product with a certain quality.
