やデツキ材等として使用されるものである。 The present invention will be explained in detail below with reference to the accompanying drawings. Reference numeral 1 denotes a mold for an extrusion molding machine, which is a cross-head die type, and has a through hole 5 in the center through which the metal substrate 2 passes, and a synthetic resin material 3 through which the metal substrate 2 passes at right angles to the through hole 5. An injection path 6 for injecting into the hole 5 is formed, and the front side of the injection path 6 of the through hole 5 is wider than the rear side so that the synthetic resin material 3 is extruded forward from the injection path 6 together with the metal substrate 2. In addition, a plurality of straight grooves 4 are provided in the through hole 5 in front of the injection path 6 as shown in FIG. As shown in FIG. 1, when a metal substrate 2 such as a zinc-treated steel plate coated with an adhesive 7 on the surface is fed in from behind, polyvinyl chloride, etc. The resin material 3 is extruded forward together with the metal substrate 2 to cover the surface of the metal substrate 2 with a coating layer 3a, and at the same time, the concave grooves 4 of the mold 1 form protrusions 3b on the surface along its longitudinal direction. . Here, the extrusion speed of the synthetic resin material 3 is set higher than the feed speed of the metal substrate 2, so after being extruded from the exit of the mold 1, the synthetic resin material 3 will escape in the direction where it is structurally weaker. shall be. Here, due to its viscosity, the synthetic resin material 3 flows at approximately the same speed as the metal substrate 2 near the metal substrate 2,
In a portion away from the metal substrate 2, the flow will be faster than that of the metal substrate 2. Since the groove 4 is formed in the mold 1 and the protrusions 3b are formed on the surface of the coating layer 3a, it is structurally weaker than the base of the coating layer 3a and the protrusions 3b near the metal substrate 2. The synthetic resin material 3 flowing quickly at the tip of the protrusion 3b tries to escape in the width direction of the protrusion 3b, and as a result, the tip of the protrusion 3b becomes longer than the base of the protrusion 3b in the extrusion direction. If the tip of the protrusion 3b is longer than the base in this way, the tip has to meander, and the protrusion 3b has a meandering tip in the width direction.
is formed on the surface of the covering layer 3a. Therefore, the coating layer 3a and protrusions 3b close to the metal substrate 2
However, the tip portion of the protrusion 3b away from the metal substrate 2 meanders in a wavy manner in the width direction of the protrusion 3b. This waving phenomenon is more pronounced as the width of the protrusion 3b is narrower and the height thereof is higher.Therefore, where a straight protrusion is required as a whole, it is sufficient to make the protrusion wider and shorter. In this way, the protrusions 3b are made to meander due to the difference in the feed speed between the metal substrate 2 and the synthetic resin material 3, so if the feed speeds of both are constant, a substantially uniform meandering shape can be obtained, and the feed speed By appropriately varying , a wide variety of meandering shapes can be obtained. Note that the coating layer 3a
The protrusions 3b are made of soft synthetic resin, hard synthetic resin, soft low-foaming synthetic resin, etc.
There is no problem even if the adhesive 7 is not applied to the surface of the metal substrate 2. This building material A is used, for example, as a flooring material, a decking material, or the like.

るという利点がある。 As described above, the present invention feeds a metal substrate into the mold of an extrusion molding machine, and extrudes a synthetic resin material onto the surface of the metal substrate at an extrusion speed higher than the feeding speed of the metal substrate 2 to coat the surface of the metal substrate. In addition to being coated with a layer, protrusions are formed on the surface of the coating layer by grooves in the mold that are narrower in width than the through-hole through which the metal substrate passes in a cross section perpendicular to the extrusion direction. Due to the difference between the feed speed of the metal substrate and the extrusion speed of the synthetic resin material, a wavy phenomenon occurs naturally in the protrusions, forming a wavy pattern. It has the advantage of being able to form building boards with a continuous undulating pattern.
