Description

[Detailed Description of the Invention] This invention is made of fiber-reinforced plastic (hereinafter referred to as
This project concerns the improvement of swimming pools made of FRP (FRP).

FRP boules are generally manufactured in a factory with each segment being assembled at the installation site. It is necessary to specify the size and shape of each segment from the viewpoint of mass production and manufacturing cost, and on the other hand, the dimensions and course spacing of the pool vary depending on user requests. Furthermore, the side walls at both lengthwise ends of the pool are formed to have rough surfaces to prevent slipping during turns, but it is difficult to draw clear course marks on these rough surfaces. In other words, in the past, minute irregularities were formed on the entire surface of the side wall to make the entire surface rough, and colored paint was sprayed on this after masking with adhesive tape, but this only took a lot of time and effort to position the adhesive tape. Because the masking surface was rough, paint seeped in from the edges of the masking, creating jagged lines at the boundaries of the marks, making it impossible to draw clean marks.

This invention was made to solve these conventional drawbacks, and the object of the invention is to provide a pool structure that functions to prevent slipping when turning and also allows neatly drawn marks. It is. That is, in a pool formed by combining a plurality of fiber-reinforced plastic segments, the side walls at both lengthwise ends are formed into a rough surface consisting of an uneven surface, and this rough surface is an aggregate of square or rectangular uneven surface areas. A smooth surface continuous in the vertical and horizontal directions is formed between each uneven surface area.

Embodiments of the present invention will be described below with reference to the drawings. Figure 1 shows the completed state of the pool, with bottom wall 1,
Side wall 2 at the end in the length direction and side wall 3 at the end in the width direction
are each formed by combining a plurality of segments, but their connecting portions are not shown. A course mark 11 is written on the bottom wall 1, a drain groove 13 is opened in the upper part of the side wall 3, and a drain groove 14 is opened in the upper side of the side wall 2 in the horizontal direction. Further, the side wall 2 has a smooth surface 5 formed near the bottom and a rough surface 4 above it, and course marks 7 are drawn on both surfaces.

As shown in FIGS. 2 and 3, the rough surface 4 has a large number of square or rectangular uneven surface regions 6 formed therein, and a narrow smooth surface 8 formed between each region 6 in the vertical and horizontal directions. There is. The shape of the unevenness in the area 6 can be a satin pattern or various other shapes.

The course mark 7 is written on the side wall 2 by pasting a masking adhesive tape 9 at a predetermined position and spraying a predetermined paint onto the portion not covered by the tape 9. At this time, if the end of the tape 9 is placed on the smooth surface 8,
Since the tape 9 is in complete surface contact, the sprayed paint will not seep into the underside of the tape 9.
Therefore, the boundary of mark 7 is drawn as a clean straight line. Further, positioning of the tape 9 is very easy if the tape 9 is attached so that the end of the tape is along the smooth surface 8. Note that if the width of the smooth surface 8 is set to, for example, about 10 mm and the width of the region 6 is set to about 40 mm, the position of the mark 7 can correspond to any course interval with an error of within 25 mm. In other words, the distance between one vertical smooth surface 8 and the adjacent smooth surface 8 is 50 mm, so by positioning the vertical end of the mark 7 on either smooth surface 8, the distance between the two can be reduced. Positioning can be performed within a half dimension (25mm), and therefore, when the course spacing changes, it is possible to accommodate any course spacing with an error within 25mm.

As explained above, the present invention forms a rough surface on the side wall of a pool to prevent slipping, and also forms smooth surfaces with narrow widths in the vertical and horizontal directions at predetermined intervals in the rough surface, and the course mark It is easy to fill in and allows neat marks to be written.
