Hereinafter, an embodiment of the present invention will be described.

Reference numeral 1 denotes a joint plate material for joints to be loaded, erected, inserted, installed, etc. in a joint of a central separation zone, a road, a side wall, or another structure, and the joint plate material 1 is plywood or asphalt. It is composed of an impregnated bituminous fiber material, a plastic material (possibly waste material), a plate material such as rubber, or a composite plate material of each of the above materials.

The first example of FIGS. 1-1 and 1-2, the first example of FIG. 2-1 and 2-2, and the other first example are examples of cutting the joint plate material 1 and manufacturing the joint plate material 1. In the example, the joint plate material 1 is a first long plate 100 having a rising height L serving as a core (a structure of integrally molding the joint plate material 1-1, which will be described later), and the first long plate 100. A second side having approximately 1/3 L of rising height provided so as to be flush with each other on both side surfaces 100a / 100b and the upper and lower ends 100c / 100d, and having inclined surfaces 2 to 5 on the opposite side to be described later. It is composed of short plates to fifth short plates 101 to 104, and at least four of the four second short plates to fifth short plates 101 to 104 provided on both sides of the first long plate 100. When attached to 100a and 100b, intervals 6 and 7 are formed on the opposite side thereof. In the first example of FIG. 1-1, the second short plate 101 to the fifth short plate 104 have the same rising height of approximately 1/3 L. Further, in another first example of FIG. 1-2, the second short plate 101 and the fourth short plate 103 have a rising height of approximately 1/3 L, and the third short plate 102 and the fifth short plate 104 rise. The height is approximately 1 / 2.5L. That is, another first example is a configuration in which the lower third short plate 102 and the fifth short plate 104 are formed longer than the upper second short plate 101 and the fourth short plate 103, which is uneven. .. As a general rule, the inclination angles of the inclined surfaces 2 to 5 are the angles described later. Further, the wall thickness W of the first long plate 100 and the second short plate 101 to the fifth short plate 104 is the same.

Then, when the second short plate to the fifth short plate 101 to 104 are attached to both side surfaces 100a and 100b of the joint plate material 1, the both side surfaces 100a and 100b and the second short plate to the fifth short plate are formed. Notches 10 to 13 having inclined surfaces are formed between the inclined surfaces 2 to 5 of the plates 101 to 104, respectively. In addition, when attaching, as a general rule, the upper and lower ends 100c and 100d of the first long plate 100 and the upper ends 101a and 103a or the lower ends 102b and 104b of the second short plate to the fifth short plate 101 to 104 are used. , Become flush. At the time of this attachment (adhesion, nailing, etc.), the inclined surface 2 of the second short plate 101 and the inclined surface 3 of the third short plate 102 face each other, and the inclined surface 4 of the fourth short plate 103 , The structure is such that the inclined surface 5 of the fifth short plate 104 faces the inclined surface 5.

The notches 10 to 13 provided with the inclined surface have an inclination angle of 40 ° to 80 ° formed by the inclined surfaces 2 to 5 and the vertical side surfaces 101c to 104c in order to exert a weed control effect. , Desirably 65 ° to 75 °. This makes it possible to block the phototropic and geotropic properties of plants. In particular, in the example of cutting and manufacturing the joint plate material 1, the inclination angle of the second short plate 101 to the fifth short plate 104 can be secured at 45 ° by setting the inclination angle to 45 ° at the time of cutting. .. Further, by ensuring an inclination angle of 45 °, the inclination angle 45 between both cut pieces , for example, the second short plate 101 ( fourth short plate 103 ) and the third short plate 102 (fifth short plate 104). There is an advantage that ° can be secured. In some cases, even if the inclination angle is 40 °, if the inclination length of the inclined surface 5 can be secured, for example, about 1 cm to 2 cm (when the joint plate material 1 is considered as a thickness of 1 cm), it is prevented. A grass effect can be expected.

Further, the structure of the second short plate 101 and the third short plate 102, the structure of the fourth short plate 103 and the fifth short plate 104, and / or the structure of the inclined surface 2 and the inclined surface 4, and the inclined surface 3 And the structure of the inclined surface 5 are in a confrontational relationship. Therefore, it has the effect of withstanding the expansion and contraction of concrete (enabling the anchoring function) and / or the effect of preventing the joint plate 1 and the like from rising (enabling the anchoring function).

The assembly structure described above describes, for example, an example of manufacturing from a single plate material from the viewpoint of cost reduction, small lots, etc., but other moldings include, for example, mass production. From the viewpoint of ensuring quality, it is also possible to use a method such as integral molding, pultrusion molding, casting, or casting molding.

It should be noted that this is another example in which the joint plate material 1 shown in FIG. 4 is cut and used, and is most suitable for a structure in which concrete X (paving material) is shallow, for example. Its structure conforms to the above-mentioned joint plate material 1. Therefore, the same form and mechanism are designated by a common reference numeral. The effect is also similar to that of the joint plate material 1. Although not shown, it may be manufactured from the beginning.

The joint plate material 1 is laid in the joint 21 formed in the transverse direction of the median strip H according to the usage as shown in FIGS. 2-1 and 2-2. Normally, at the time of placing concrete X, a joint 21 is made by operating a joint bar, and after the work is performed, the joint 21 is inserted into the joint 21. After insertion, even if the seeds are present between the roadbed 22 or the joint plate material 1 and the concrete X, the inclination angle of the notches 10 to 13 having the inclined surface has a weed-proof effect, that is, the bending of the plant. It can block the properties of phototropism and bending. Further, in the joint plate material 1 having the structure of FIG. 1, the notches 10 to 13 having four inclined surfaces are connected to the four concrete Xs cast, and / or the intervals 6 and 7 are formed. Since it has, the connection between the two is strengthened, and there is a practical benefit (delamination suppression) that the separation of the two is reduced even with respect to the expansion and contraction of the concrete X. Moreover, the notches 10 and 12 having a pair of inclined surfaces of notches 10 to 13 having four inclined surfaces and the notches 11 and 13 having the inclined surfaces secure a confrontational relationship. The effect is maximum. It is also effective against expansion and contraction of concrete X due to freezing. Further, the burying depth of the joint plate material 1 in the roadbed 22 or the like is an example and is not limited (the same applies to each of the other examples).

The second example of FIGS. 7-1 and 7-2, the second example of FIG. 8-1 and FIG. 8-2, and the other second example have a structure in which the joint plate material 1-1 is integrally molded, and is a mold or extrusion. Manufactured using equipment such as molding. As for the structure, the core of the joint plate material 1-1 is the first long plate portion 100-1, and the side surfaces 100-1a and 100-1b thereof are notches 10 having inclined surfaces from the outside to the inside. At least four second short plate portions 101-1 to fifth short plate portions 104-1 having -1 to 13-1 are bulged out. Other structures conform to the first examples of FIGS. 1-1 and 1-2 described above. Also, structures that have the same form and effect use the same code and name. Further, when adopting the examples of FIGS. 4 and 5, it is necessary to change the mold or the like.

In addition, 101-1a and 103-1a are the upper ends of the portions of the second short plate portion 101-1 and the third short plate portion 103-1, and 102-1b and 104-1b are the third short plate portions. Each lower end of the portion 102-1 to the fourth short plate portion 104-1, and 101-1c to 104-1c are the portions of the second short plate portion 101-1 to the fourth short plate portion 104-1. Each aspect is shown individually.

Then, in the second example of FIG. 7-1, the second short plate portion 101-1 to the fifth short plate portion 104-1 have the same rising height of approximately 1/3 L. Further, in another second example of FIG. 7-2, the second short plate portion 101-1 and the fourth short plate portion 103-1 have a rising height of approximately 1/3 L, and the third short plate portion 102-1 The fifth short plate portion 104-1 has a rising height of approximately 1 / 2.5 L. That is, in another second example, the upper second short plate portion 101-1 and the fourth short plate portion 103-1 are compared with the lower third short plate portion 102-1 and the fifth short plate portion 104-. 1 is a long formed structure and is uneven. Others are the same as the above-mentioned first example or the other first example.

Further, as shown in FIG. 9, in the conventional joint material, the breeding frequency of weeds is remarkable, and there are problems such as aesthetics and traffic obstacles, and labor and labor required for annual weeding.

Each of the above-mentioned examples and the like is a description of a preferable example of the present invention. It is not limited to each embodiment or drawing. Therefore, a structure in which a part of the configuration is changed within the scope of the invention, a structure in which the same features and effects can be achieved, and the like are within the scope of the present invention.
