Description

[Technical Field]

[0001] The present invention relates to a diving board installed at the side of a pool. [Background technology]

[0002] Diving boards used in 3m springboard diving, a type of swimming competition, are generally constructed by placing a springboard supported by a stand, such as that described in Patent Document 1, on a concrete platform set up on the side of the pool. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Special Publication No. 2020-536710 Summary of the Invention [Problem to be solved by the invention]

[0004] When setting up a temporary diving board in a pool that does not currently have one, the diving board can be constructed by placing a floor board on a base constructed of steel columns and steel beams, and then fixing a stand that supports the diving board onto the floor board.

[0005] However, because the frame constructed from steel columns and beams is less rigid than a concrete frame, there was a problem in that the frame was unable to adequately suppress the vibrations and noise generated by the springboard during springboard diving competitions.

[0006] The present invention was made in consideration of these problems, and its purpose is to provide a diving board that can sufficiently suppress the vibration and noise of the springboard even when the frame is constructed of steel columns and steel beams. [Means for solving the problem]

[0007] The diving board of the present invention is a diving board installed on the side of a pool and equipped with a springboard, and is characterized by having a base constructed of steel columns and steel beams, a base plate installed on the steel beams, a floor plate installed on the base plate with spacers sandwiched between them, a stand fixed on the floor plate and supporting the springboard, and a sandbag placed between the base plate and the floor plate.

[0008] In the diving board of the present invention having the above configuration, the base plate is preferably formed of a steel plate. [Effects of the Invention]

[0009] According to the present invention, a diving board can be provided that can sufficiently suppress the vibration and noise of the springboard even when the frame is constructed of steel columns and steel beams. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0011] A diving board according to one embodiment of the present invention will be described in detail below with reference to the drawings.

[0012] 1, 2 and 3, a diving board 1 according to one embodiment of the present invention is installed beside a swimming pool 2, i.e., on the poolside 3, and is used for 3m springboard diving, a type of swimming competition. A springboard 4 is installed on the diving board 1 so that it is 3m high above the water surface of the pool 2, and competitors can use the springboard 4 to compete in 3m springboard diving.

[0013] The diving board 1 may be configured so that the height of the springboard 4 from the water surface of the pool 2 is set to 1 m, and the diving board 1 may be configured so as to be used for 1 m springboard diving, which is a type of swimming competition.

[0014] The pool 2 and the poolside 3 are each made of concrete, and the diving board 1 is provided on a floor 3 a of the poolside 3 .

[0015] A plurality of diving boards 1 are lined up on the poolside 3, but this embodiment will describe only one of the diving boards 1. However, the poolside 3 may be configured to have only one diving board 1.

[0016] The diving board 1 has a base 10, a base plate 20, a floor board 30, a stand 40, and a sandbag 50.

[0017] The frame 10 is constructed of steel columns 11 and steel beams 12, 13. More specifically, the frame 10 has four steel columns 11 arranged inside the four corners of the frame 10, four steel beams 12 placed on the upper ends of adjacent steel columns 11 and fixed thereto, and seven steel beams 13 fixed to two adjacent steel beams 12 so as to be parallel to the edge of the pool 2. Note that when the steel columns 11 and steel beams 12, 13 are constructed by combining multiple steel frames (two frames), such as the steel beam 12 arranged below the stand 40 in FIG. 1, the steel columns 11 and steel beams 12, 13 made up of multiple steel frames are counted as one. The lower ends of the steel columns 11 are fixed to supports 14 provided on the floor 3a of the poolside 3 using fastening members such as bolts and nuts. In other words, the frame 10 is constructed on the floor 3a of the poolside 3.

[0018] In this embodiment, the steel column 11 and the steel beams 12, 13 are each formed of a channel steel. Note that the steel column 11 and the steel beams 12, 13 may also be formed of steel frames of other shapes, such as square steel pipes.

[0019] The frame 10 may be configured such that brace materials 15 are provided between adjacent steel columns 11. Furthermore, the number of steel columns 11, the number of steel beams 12 and 13 constituting the frame 10, and the arrangement of the steel columns 11, steel beams 12 and 13, and brace materials 15 are not limited to those described above and may be changed as appropriate. Furthermore, the front portion of the frame 10 facing the pool 2 may be covered with a wall 16.

[0020] The base plates 20 are placed on the steel beams 12 and 13. As shown in Figs. 4 and 5, in this embodiment, three base plates 20 each made of a steel plate are arranged side by side on the steel beams 12 and 13 of the frame 10. As shown in Fig. 3, the three base plates 20 are arranged so as to cover all of the upper ends of the four steel columns 11. Each base plate 20 is a rectangular plate provided with a plurality of fixing holes for fixing to the steel beams 12 and 13 or a plurality of fixing holes for fixing the stand 40, and is fixed to the steel beams 12 and 13 using these fixing holes and fastening members such as bolts and nuts (not shown).

[0021] The shape, size, etc. of the base plate 20 can be changed in various ways, for example, it can be made of a single steel plate, as long as it is large enough or has a shape that can cover all of the upper ends of the four steel columns 11. Furthermore, the base plate 20 is not limited to being made of a steel plate, and may be made of other plate materials such as plywood (wood laminated plate material).

[0022] If the base plate 20 is made of a steel plate, the rigidity of the stand 10 can be increased and the weight of the foothold portion provided on the stand 10 can be increased, thereby suppressing the shaking of the stand 10 due to the vibrations generated by the springboard 4.

[0023] 4, a plurality of spacer bodies 21 are arranged on the substrate 20 at intervals from one another in parallel with the steel beams 13. The plurality of spacer bodies 21 may be formed of, for example, square timber (wooden pieces in the shape of a rectangular pillar), but are not limited to this.

[0024] The floorboards 30 are installed on the base plate 20 with spacers 21 sandwiched between them, and form the foothold (platform) for the diving board 1. In this embodiment, the floorboards 30 are made of wood, with a non-slip vinyl pool floor sheet 32 ​​attached to plywood (wood laminated board material) 31. However, the floorboards 30 may have other configurations as long as they can be installed on the base plate 20 with the spacers 21 sandwiched between them to form the foothold for the diving board 1.

[0025] The stand 40 supports the springboard 4. In this embodiment, the stand 40 is divided into a rear end support part 41 that supports the rear end of the springboard 4, and an intermediate support part 42 that supports the middle part of the springboard 4. The intermediate support part 42 may be equipped with a dial 42a for adjusting the position at which the springboard 4 is supported.

[0026] The rear end support part 41 and the intermediate support part 42 are each fixed onto the floor panel 30. More specifically, as shown in FIG. 4 , a pair of front and rear base bodies 43 fixed to the steel beam 13 via the base plate 20 are disposed between the floor panel 30 and the base plate 20 in the portion where the rear end support part 41 is disposed and the portion where the intermediate support part 42 is disposed, and the rear end support part 41 and the intermediate support part 42 are each fixed onto the floor panel 30 by being fixed to the corresponding base body 43 using anchor bolts 44 while disposed on the floor panel 30. In other words, the rear end support part 41 and the intermediate support part 42 are connected and fixed to the steel beam 13 via the corresponding base body 43 and the base plate 20, respectively.

[0027] Sandbags 50 are disposed between substrate 20 and floorboard 30. More specifically, of the spaces partitioned by spacer bodies 21 between substrate 20 and floorboard 30, sandbags 50 are disposed in each space except for the space in which base body 43 is disposed. Sandbags 50 are bags filled with sand, and multiple sandbags 50 are spread tightly on substrate 20 in each space.

[0028] The number and arrangement of the sandbags 50 disposed between the base plate 20 and the floorboard 30 can be changed as appropriate.

[0029] In this way, in the diving board 1 of this embodiment, the base 10 is constructed of steel columns 11 and steel beams 12, 13, a base plate 20 is placed on the base plate 20, and a floor plate 30 is placed on the base plate 20 with spacers 21 in between, and a stand 40 supporting the springboard 4 is fixed on the floor plate 30, and sandbags 50 are placed between the base plate 20 and the floor plate 30, thereby increasing the weight of the foothold portion placed on the base plate 10 and sufficiently preventing the base 10 from shaking due to vibrations generated by the springboard 4 during competition, and also absorbing the sound generated by the springboard 4 and sufficiently suppressing said sound.

[0030] The gantry 10 can be configured to include support columns 60. In this embodiment, the gantry 10 is provided with three support columns 60 corresponding to the rear end support portions 41 and three support columns 60 corresponding to the intermediate support portions 42.

[0031] The support pillars 60 may be formed of, for example, channel steel, but may also be formed of steel frames of other shapes, such as square steel pipes.

[0032] The support columns 60 are arranged below the stand 40. That is, the three support columns 60 corresponding to the rear end support section 41 are arranged below the rear end support section 41, and the three support columns 60 corresponding to the intermediate support section 42 are arranged below the intermediate support section 42.

[0033] More specifically, the three support columns 60 arranged below the rear end support section 41 of the stand 40 are each arranged below a portion of the rear end support section 41 that is fixed to the base body 43 or the floor board 30 by anchor bolts 44. The upper end of each support column 60 is fixed to the steel beam 13, and the lower end is fixed to a support base 61 provided on the floor 3a of the poolside 3 using fastening members such as bolts and nuts. The support base 61 may be formed, for example, by mortar (grout) filled between the floor 3a of the poolside 3 and the lower ends of the support columns 60.

[0034] Similarly, the three pillars 60 arranged below the intermediate support section 42 of the stand 40 are each arranged below the portion of the intermediate support section 42 that is fixed to the base body 43 or the floor board 30 by anchor bolts 44. The upper end of each pillar 60 is fixed to the steel beam 13, and the lower end is fixed to a support base 61 provided on the floor 3a of the poolside 3 using fastening members such as bolts and nuts. The support base 61 may be formed, for example, by mortar (grout) filled between the floor 3a of the poolside 3 and the lower ends of the pillars 60.

[0035] The support pillars 60 only need to be arranged so that at least a portion thereof is located below the stand 40, i.e., the rear end support portion 41 or the intermediate support portion 42, in a plan view. Furthermore, as long as at least one support pillar 60 is arranged below the stand 40, the number and arrangement of the support pillars 60 arranged below the stand 40, i.e., the rear end support portion 41 or the intermediate support portion 42, can be changed as appropriate. Note that the pedestal 10 may be configured without the support pillars 60.

[0036] When such a configuration is provided with the support pillars 60, the vertical load applied from the diving board 4 to the platform 10 via the stand 40 during competition is directly supported by the support pillars 60, and the vibrations and noise generated by the diving board 4 can be suppressed by the platform 10.

[0037] The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and scope of the present invention. [Explanation of symbols]
