2. Description of the Related Art Surface materials used in freezers, refrigerators, containers and the like, for example, floorboards and walls are formed by molding and piers are used for reinforcement. Conventionally, natural woods such as lauan, zelkova, teak, oak, and the like have been used as crosspieces. This is based on the fact that natural wood has a very high strength, is excellent in workability, can be screwed, and is inexpensive. However, in recent years, from the viewpoint of protection of natural resources, crosspieces made of synthetic resin foam have been adopted for general houses.

[0003] These conventional natural woods have insufficient heat insulation performance, and are only about 1/5 to 1/6 of the foamed body. Although the synthetic resin foam has good heat insulating properties, it is not practical because it has low strength and cannot be fixed to a floor material with screws, bolts, nails, or the like. Non-foamed synthetic resin has high strength, can be screwed, etc., but is expensive and has low heat insulation.

In the present invention, as shown in FIG. 1, a pier (3) in which a low-foamed material is used as a core material (1) and four surfaces along its longitudinal direction are covered with a hard synthetic resin layer (surface layer) (2). Was manufactured by co-extrusion molding, but the adhesion between the foam core and the surface layer was poor, causing peeling and strength reduction especially at hot low temperatures, or depending on the resin, foam insulation material (mainly urethane) embedded around the pier There was a problem in the adhesiveness and the screw pull-out strength at the time of screwing.

The present invention provides a long core material (1).
In the crosspiece (3) whose four surfaces along the longitudinal direction are covered with a surface layer (2), the core material is a low polystyrene foam, and the surface layer is 5 to 25% by weight of a polyphenylene ether resin and 65 to 94% by weight of a polystyrene resin. And a pier made of a mixed resin containing 1 to 10% by weight of a rubber component.

The long core material (1) is generally, but not limited to, 50 to 100 mm in length, 20 to 70 mm in width, and 2,000 in length.
It is a low foam synthetic resin of up to 2500 mm. The expansion ratio is 1.
It is 5 to 5 times, preferably 2.5 to 3.5 times. If the expansion ratio is smaller than this, the heat insulating properties become insufficient, and if it is larger than this, the strength is reduced.

Since the core material is insufficient in strength as it is, a hard synthetic resin surface layer (2) is formed on this surface. As shown in FIG. 2, the surface layer made of the synthetic resin is screwed, bolted, or nailed to the plywood (4) and the flooring (5), and the surface in contact with them must have a thickness necessary for screwing. . Its thickness is usually 2 to 15 mm, especially 4 to 8 mm. The thickness of the remaining two surfaces may be determined from the strength required to support the crosspiece against the pressing. The thickness of the remaining two surfaces when the core material and the surface layer are completely joined is generally 0.1 to 2 mm, particularly 0.5 to 1 mm.

The core material and the material of the surface layer can be co-extruded to form a completely adhered molded product, and the core material can be a hard low-foamed material having excellent heat insulating properties. The surface layer is a synthetic resin capable of imparting a high screw pull-out strength, and a high pressure-resistant strength can be obtained even if the thickness of the side surface is small. In addition, a urethane foam layer embedded between the crosspieces as a heat insulating material (see FIG. 3) It is desired to have high adhesiveness to (9)). If the adhesiveness between the urethane foam layer and the surface layer on the side of the pier is poor, gaps are formed under freezing conditions, and the heat insulating effect is significantly reduced.

[0010] The combination of the core material and the surface layer is very important from the following points. The present inventor has found that the surface layer contains 5 to 25% by weight of polyphenylene ether resin and 65 to 94% of polystyrene resin.
Using a mixed resin of 1% to 10% by weight of a rubber component and a polystyrene low foam as a core material, the expansion ratio of the low foam is 1.5 to 5 times, particularly 2.5 to 3.5 times. It has been found that the above requirements are satisfied when used.
