JPH0656103U - Bark paving board - Google Patents

Abstract

(57) [Abstract] [Purpose] The present invention is a bark pavement board used for roads, promenades, stadiums, etc., which has elasticity and water permeability, and can be jumped or run. Also, the reaction force is not transmitted to the lower back and does not cause back pain or the like. [Structure] The bark is finely cut into bark pieces 1, and a binding material 2 is mixed and kneaded into the bark, which is then inserted into an appropriate mold 4 and pressed by a temperature control plate 5 from above and below. It is a molded product.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bark paving board which is used for roads, promenades, stadiums, etc., and which has excellent elasticity and water permeability.

[0002]

[Prior art]

 In recent years, sports such as jogging and suckers have been actively performed for health. However, the places where jogging is performed were mainly asphalt, concrete pavement, and turf.

[0003]

[Problems to be solved by the device]

 These are generally very hard materials, and if they bounce or run on them, the reaction force will be transmitted to their waists. If this state is continued for a long time, the back will be strained, causing back pain.

[0004]

[Means for Solving the Problems]

 Therefore, the present invention was proposed in order to solve the above-mentioned inconvenience, and its composition is to cut the bark into fine pieces of bark, add a binder to this, and knead them with a mixer or the like. This is put into an appropriate mold and pressure-contacted from the upper and lower surfaces with a temperature control plate through which hot water is passed through to cure and mold. When such a pavement board is constructed with high elasticity and water permeability, it has the advantages that it does not cause back pain and that drainage such as rainwater is good.

[0005]

【Example】

 Next, the drawings will be described. 1 is a bark piece obtained by finely cutting a relatively thick bark such as Kara pine, fir tree, birch, beech, etc., and has a size of several (1) to several (10) (4). Reference numeral 2 denotes a binder for the bark piece 1, which is urethane resin, epoxy resin, latex, pine resin, or the like, and is kneaded with the bark piece 1 in the mixer to form a bark paving board. Reference numeral 3 is a concrete adhered to one surface of a bark paving board. In order to manufacture the present invention, as shown in FIG. 2, for example, a mixture of the bark piece 1 and the binding material 2 is put into a square formwork 4, and this is shown in FIG. As described above, it is manufactured by interposing between the temperature control plates 5 and 5 in which hot water is passed, curing and demolding. Further, in order to construct the one in which three layers of concrete are provided (FIG. 4), as shown in FIG. 5, a bark paving board is inserted into the bottomed formwork 6, and then As shown in FIG. 6, the concrete 3 is cast, cured, and released from the mold. FIG. 7 shows a cross section of a pavement board constructed, where 7 is a stone material as a base material and 8 is a drainage pipe for rainwater or the like. Reference numeral 9 denotes a hot water pipe, which is connected to the hot water passage of the temperature control plate 5 and the water heater to heat the temperature control plate 5.

[0006]

[Action]

 Since the present invention has the structure as described above, in order to construct it, a stone 7 such as crushed stone, cobblestone, etc. is laid, and a drainage pipe 8 is buried under the stone 7 and is placed on the stone 7. , Laying a bark paving board.

[0007]

[Effect of device]

 In the present invention, a bark piece 1 is hardened with a binder 2, and since the bark has an indefinite shape, air is entrained when it is mixed so that it creates voids and becomes porous, and it becomes a cushion even when running or bouncing. , It reduces the impact and does not place an unreasonable burden on the lower back and spine. Also, unlike conventional concrete and asphalt, it has a high degree of elasticity, has no sharp edges, and is very soft, so it does not suffer bruising or scratching even if it falls. Further, the present invention is easy to process, can be constructed according to the terrain, and is porous so that rainwater can permeate well and drain well. As shown in FIG. 4, when the concrete 3 is integrally formed on the lower surface, the whole plate becomes strong and the construction is easy without warping.
