が行われているに過ぎない。2. Description of the Prior Art Polyolefin-based molding materials such as polyethylene and polypropylene are rigid and are used as pseudo-wood and structural materials as large solid or hollow products such as cylinders and prisms.
The moldable length limit is 1.5-2 m. If a length of 3 to 4 m or more is required, it is necessary to join a plurality of pieces. However, it is very difficult to firmly bond the polyolefin molding material with the adhesive. There is also a method in which a flange portion is formed at the joint ends of the molding materials and the flange portions are mechanically joined, but the joint portion projects from the side portion, which is not preferable in terms of appearance and construction. Further, there is a heat fusion method as a method for joining polyolefin-based molding materials, but this method is intended for small articles. This method is performed by accurately cutting the mutual fusion surfaces into flat surfaces, and since large-sized materials have a large welding heat capacity and are difficult to use even with a welding machine, they are limited to indoor work. At present, hot air welding is used only for air-conditioning ducts having a thickness of several mm.

A method for bonding a polyolefin-based molding material is provided. The adhesive is not particularly limited as long as it can be firmly adhesively bonded to a metal, but an epoxy resin adhesive is particularly preferably used from the viewpoint of excellent adhesiveness, handleability, weather resistance and the like.

An annular metal disk 4 having a nail hole 3 formed in the upper artificial wood 1 and an annular metal disk 5 in the lower artificial wood are similarly mechanically joined by driving screw nails 6 as shown in FIG. It Next, an epoxy resin adhesive 7 is applied to these metal discs 4 and 5, and the metal discs are adhered to each other, so that the upper pseudo-tree 1 and the lower pseudo-tree 2 are formed as shown in FIG.
To join. After the adhesive is hardened, the excess adhesive that has run off is scraped off and the side surface of the bonded portion is finished.

打ち込みに際し割れを生じないものであればよい。In the above embodiment, the pseudo wood is taken as an example, but the polyolefin type molding material to be bonded is preferably applied to pseudo wood pile, other solid or hollow cylindrical material, square wood or a molding material having a similar shape. To be done. For reinforcement of a large hollow material, metal tubes may be inserted into the upper and lower hollow cylinders. In addition to the plane, the bonding end surface of the polyolefin-based molding material has a convex part or convex ring protruding upward on one side and a concave part or annular groove corresponding to this on the other side. The low peel strength of the adhesive may be compensated for by appropriately fixing the metal plates and fitting the metal plates together and adhering them together. Further, the metal plate can be formed by punching a steel plate, a light alloy plate or the like, and the thickness thereof is about 1 to 2 mm, although it depends on the size of the polyolefin molding material. In addition to screw nails, screws, screw-bolts, etc., which firmly bond to the metal plate and the polyolefin-based molding material and which do not cause cracks during driving, may be used.

Both polyolefin-based molding materials form an extremely strong bond and can be used in the same manner as those integrally molded as a structural material. Further, according to the method of the present invention, a strong bond can be obtained through adhesion between metal surfaces without using a special material and without requiring strict flatness of the bonding end surface of the polyolefin-based molding material. .
