Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a resin floor column, and more specifically, in a resin floor column having a hard urethane foam layer molded from natural name wood, the resin floor column is pre-formed with the grooves and ladle necessary for mounting between floors. Regarding the floor pillar.

[0002]

[Prior art]

 Recently, regulations on deforestation in the South Sea have become stricter due to global environmental issues, and it is said that this regulation tends to spread to each country. Under these circumstances, there is a growing demand for economical plastic products to replace wood. Resin floor columns are an example of products that meet the above social needs.

The resin floor pillar can be obtained by integrally molding a wooden core material and hard urethane foam using a silicone rubber mold in which a natural name tree is molded, and has an aesthetic appearance very similar to that of the natural name tree. It has the features that it can be applied, there is no problem of cracking like natural name trees, and that it does not turn red like natural name trees because it is coated with a weather-resistant paint, and mold hardly occurs.

[0004]

[Problems to be solved by the device]

 However, the above-mentioned conventional resin floor columns also require grooving and lapping, which are troublesome when mounting between floors, like the floor columns of natural wood, and improvements in this respect have been desired. For example, in order to fix the floor pillar to the wall, a work is usually performed on the back crack portion of the floor pillar to embed the wall end portion. However, the size of each natural name tree is different, the bending is not uniform, and the difference in diameter between the tip and the root is also different.

Therefore, when grooving to fill a wall so that the columns stand upright at almost right angles, it is necessary to dig deeper as going from the tip to the root. However, the position of the groove and the depth of the groove from the outer circumference are required. Since there is a difference in the relationship with each one, even in the case of automatic processing, it was necessary to adjust the degree of inclination of the column with respect to the horizontal, and there was a problem in processing it. Furthermore, in the case of manual processing, considerable skill is required, and there is a problem that man-hours are required.

In addition, there is a more difficult problem in lapping the sliding contact surface. In other words, if the sliding surface of the sliding door is slid after the groove is fitted into the wall, the frame at the bottom of the sliding door will be removed when the pillar is largely bent or the root is considerably larger than the tip. There was a problem that it was hidden behind the pillars and spoiled the appearance of the sliding doors. To prevent this, a shallow lapping process naturally caused gaps because the upper part of the fusuma and the column lapping surface did not reach.

Thus, setup and processing are difficult and time-consuming, and it has been strongly desired to solve this problem. The above problems are common to the floor columns of natural wood and the resin floor columns molded from them.However, in the resin floor columns, the foamed cell surface is exposed on the lapping surface, which is not preferable in appearance. .

The present invention solves such a problem, and is an economical resin-made groove that does not require groove processing or lapping surface processing required for mounting between floors in a resin floor pillar. The purpose is to provide a floor pillar.

[0009]

[Means for Solving the Problems]

 The present inventor should be able to provide, in the form of a molded article, a floor column having groove and lapping necessary for mounting between floors, instead of cutting and subsequently performing groove and lapping. It was confirmed and the problems associated with the processing up to now were solved all at once. That is, the present invention resides in a resin floor column in which a material and a rigid foamed urethane layer are integrally molded, and a resin floor column in which at least a processing groove is previously provided in the hardened urethane layer, and a core material and a rigid foamed layer are provided. In the resin floor column integrally molded with the urethane layer, the resin floor column is obtained by previously providing the hard urethane foam layer with a processed portion selected from a processed groove and a lapping surface.

[0010]

[Action]

 In the resin floor pillar of the present invention, the grooves and the lapping surface of the hard foamed urethane layer have been added in advance so that the machining time of the floor pillar and the lapping time can be greatly shortened and the material is natural wood. It is more durable and does not crack or discolor like natural wood.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a cross-sectional view of a resin floor column according to the present invention, FIGS. 2 and 3 are cross-sectional views of other resin floor columns according to the present invention having a sliding surface, and FIGS. 4 and 5 are sliding door surfaces. FIG. 3 is a cross-sectional view of another resin floor column according to the present invention having the above. The resin floor pillar 1 according to the present invention is an integrated construction laminated timber, structural laminated timber having load bearing capacity, or a core material 2 made of thinned wood or square timber and a hard foam urethane layer 3 surrounding the core material 2. It is molded. The shape of the core material 2 is not particularly limited, but a cylindrical shape, a quadrangular prism shape, an octagonal prism shape or the like is usually used.

Thus, in the floor pillar 1 of the present invention, the processed groove 5 for fitting into the wall 4 is provided in the hard foam urethane layer 3. Of course, the processed groove 5 may penetrate not only the hard urethane foam layer 3 but also the core material 2. Further, in the present invention, the sliding contact surface 8 against which the sliding doors 7 are provided is provided with a flat lapping surface 9 (see FIGS. 2 and 3) or a flat lapping surface 9 having edge portions (see FIGS. 4 and 5). Can do it

In the floor pillar manufacturing method, first, a shallow die log was used as a model to fabricate a silicone mold, and a slit portion was provided in the longitudinal direction at the center of the grooved portion to take out the molded body. Place this silicone mold in the retainer mold, set the working laminated wood as the core material in the center, cast the rigid polyurethane foam into the laminated material and the cavity of the silicone mold, and place the wooden core material and the rigid polyurethane foam. A resin floor pillar was formed by integrally molding and having a U-shaped groove for attaching to the wall and a lapping surface in contact with the fusuma. Then, the surface was painted with an acrylic urethane paint with a color tone similar to that of natural shallow logs.

The process for installing the resin floor pillar between the floors only requires the dimensioning in the longitudinal direction and the processing of the through groove into which the cross bar is fitted, and the post-processing is sufficient for about 20 minutes. On the other hand, in order to use natural name wood as a floor pillar, it is necessary to perform groove processing to be fitted on the wall, lapping the lapping surface of the sliding contact surface, dimension cutting and processing of the through groove for fitting the cross bar. It took about 4 hours to process. Therefore, in the resin floor pillar of the present invention, the post-processing time can be reduced to one-twelfth, that is, 90% of the time.

[0015]

[Effect of device]

 As described above, in the resin floor pillar of the present invention, the machining groove and lapping process time of the floor pillar can be significantly shortened by providing the hard urethane foam layer with the machining groove and lapping surface in advance, and also in terms of material. It is more durable than natural wood, and does not crack or discolor like natural wood, making it an extremely economical product.
