[Technical field to which the device belongs]

 The present invention relates to a resin Western-style column, and more particularly, to a resin Western-style column used as an entrance porch, pole, etc., having a stone or marble tone.

[0002]

[Prior art]

 Recently, regulations on deforestation in the South Sea have been tightened due to global environmental problems, and it is said that this regulation tends to spread to each country. Under such circumstances, there is a growing demand for economical plastic products that turn into wood. Resin-made Western columns are an example of products that meet the above social needs.

Conventionally, a large number of Western-style columns have been proposed, such as those obtained by molding a thermosetting resin containing short glass fibers and those obtained by coating and polishing the outer surface of a metal pipe. However, these products had problems such as poor working environment during molding, heavy weight, difficulty in post-processing when mounting the column, and metal noise when tapped, resulting in noise. Therefore, in order to solve the above problem, a resin Western-style column that can be obtained by integrally molding a wooden core material and hard urethane foam was proposed in Utility Model Registration No. 3009271.

However, although this has the advantage that it is light and does not rot, problems such as being easily scratched by impact and being easy to burn have been found. Here, we have proposed a resin Western-style column that has a configuration in which a rigid urethane foam layer is integrally molded between the outer surface member and the core material by applying the technique of integrally molding the core material and the rigid urethane foam layer. The resin-made Western-style columns had impact resistance and were non-combustible.

[Problems to be solved by the device]

 However, this was an endless joint structure of the outer surface member, where both ends of the outer surface member were overlapped and adhered, but the endless joint structure part was curled up, peeled off due to water seepage, and further the step of the endless joint structure part There was an external problem, etc. Also, as an endless joint structure, both ends of the outer surface member are bent along the outer peripheral surface and locked along the outer peripheral surface, or one end of the outer surface member is bent in a triangular shape and the other end is formed in the triangular shape. In the structure that bends so that it engages with the bent part of and is locked along the outer peripheral surface, since the outer surface member is laminated in the diameter direction of the Western column made of resin, there is a step in the endless joint structure part and there is a problem in appearance. was there.

The present invention solves such a problem, and in a resin Western-style column in which a laminated lumber, a rigid urethane foam layer and an outer surface member are integrally molded, the endless joint structure part is curled up and water is soaked in. The purpose of the present invention is to provide a resin-made Western-style column that eliminates peeling due to peeling and appearance defects due to steps in the endless joint structure.

[0007]

[Means for Solving the Problems]

 That is, the feature of the present invention which is adapted to the above-mentioned invention is a resin-made Western-style column in which a core material is embedded in a hard urethane foam layer and the outer surface of the urethane layer is coated with a thermoplastic resin on both sides of a metal sheet as an outer surface member. As an endless join structure of the outer surface member, at least both ends of the outer surface member are bent in a V shape and face each other with the respective locking surfaces facing inward of the pillar. It is in .

Here, another feature is that the bending margin of the endless joint structure is 5 mm or more.

[0009]

[Action]

 According to the present invention, in a resin Western-style column, as an endless joint structure of the outer surface member, at least both ends of the outer surface member are bent in a V shape and face each other with the respective locking surfaces facing the inside of the pillar. By doing so, it is possible to solve problems in appearance due to curling of the endless joint structure, peeling due to water seepage, and steps in the endless joint structure.

Further, since the bending margin of the endless joint structure portion is 5 mm or more, the problem that urethane is extruded during foaming of hard urethane can be solved.

[0011]

[Embodiment of device]

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. 1 is a perspective view of a resin Western-style column according to the present invention, FIG. 2 is a sectional view taken along line AA of FIG. 1, and FIG. 3 is a morphological view of an endless joint structure portion of the resin Western-style column according to the present invention. FIG. 4 is a configuration diagram of a conventional endless joint structure portion, and FIG. 5 is a configuration diagram of another conventional endless joint structure portion. A resin Western-style column 1 according to the present invention comprises a building material laminated structure, a load-bearing structural laminated structure, or a core material 2 made of thinned wood, square timber, etc. embedded in a hard urethane foam layer 3, and the urethane The outer surface of the layer is an outer surface member 7 coated with a metal sheet 5 coated with thermoplastic resins 4 and 6 on both surfaces. The double-sided coated metal sheet 5 is faced with an endless joint structure in which a locking surface 10 obtained by bending at least both ends of the outer surface member in a V shape faces the inside of the column.

The core material used here may be any of laminated wood, metal pipe pipe, resin pipe pipe, and paper pipe. The material of the metal sheet 5 constituting the outer surface member is not particularly limited, but aluminum having a high thermal conductivity and easily radiating heat is desirable. Further, the thickness of the metal sheet 5 is preferably 0.05 to 0.5 mm. Here, if the thickness of the metal sheet is less than 0.05 mm, scratches and breaks easily occur against impact and bending, and if it exceeds 0.5 mm, workability deteriorates.

Further, the thermoplastic resins 4 and 6 for coating the metal sheet 5 may be any of Teflon, vinyl chloride and acrylic film, and the thickness of the thermoplastic resin is preferably 0.1 to 0.5 mm. Here, if the thickness of the thermoplastic resin is less than 0.1 mm, bending tends to occur when bending, and if it exceeds 0.5 mm, the rigidity of the thermoplastic resin becomes large, and the workability and processing of the endless joint structure part There is a problem that it deteriorates. The thermoplastic resin 6 is preliminarily printed with a stone-tone or marble-like pattern 8. The printed pattern 8 is not limited to a stone pattern or a marble pattern.

Here, an endless join of a metal sheet whose both surfaces are coated with a thermoplastic resin is performed. As an endless joint structure, at least both ends of the outer surface member 7 are bent in a V shape, and the respective locking surfaces 10 face each other in a state of facing the inside of the column. Here, the bending margin of the endless joint structure part is required to be 5 mm or more, preferably 5 to 10 mm. If it is less than 5 mm, there is a problem that the joint is separated during molding and the urethane foam leaks from the endless joint structure. If it exceeds 20 mm, the core material comes into contact with the outer surface member, and the core material cannot be inserted into the outer surface member during molding. Further, the number of times of bending is at least once.

As a method for manufacturing a resin Western-style column of the present invention, first, a thermoplastic resin 6 having a marble-like pattern 8 printed thereon is used as the outer surface member 7 on the outer surface, and a thermoplastic resin 4 not printed is used. As shown in Fig. 3, both ends of the aluminum sheet coated on the rigid urethane foam layer side were bent and bent in a shape of 10 mm in advance so that each locking surface 10 faced the inside of the pillar. , Made endless. Next, the laminated wood, which is the core material, was inserted into the outer surface member 7 and placed in a mold, and urethane was injected between the core material 2 and the outer surface member 7 to foam. Here, the outer surface member 7 is pressed against the inner peripheral surface of the mold by the softening of the thermoplastic resins 4 and 6 due to heat generation when urethane foams and the foaming pressure of urethane. Then, when the molding temperature is lowered, the thermoplastic resins 4 and 6 become hard and are set along the inner peripheral surface of the mold, and the resin Western-style column 1 is completed.
