[Task]
In the boundary block with a phosphorescent material as described above, it is necessary to form a recess, apply an adhesive, and fit the phosphorescent material into the recess in order to attach the phosphorescent material. It takes a lot of work. I want to easily add a phosphorescent function to the boundary block.

[Idea]
The boundary block is a precast concrete block and is heavy to handle manually. A machine that lifts heavy objects may be used when constructing a large number of lines arranged on a road. There is a type in which the boundary block is embedded with an insert for connecting a hanging tool.

  In the boundary block with an insert, the insert opens on the upper surface of the boundary block, and is configured to be inserted and connected to the shaft portion of the hanger. After the lifting operation, the lifting tool is removed from the insert. The insert then closes the opening by fitting a plug-type lid into the opening. The upper surface of the lid is exposed to the outside air.

  Therefore, at least the upper surface of the lid of the insert is made phosphorescent. If a lid having a phosphorescent property is attached to the boundary block with an insert, the boundary block with the insert is easily provided with a phosphorescent function.

  In order to make the lid phosphorescent, if the lid is a synthetic resin molded product, the phosphor is mixed with the raw material resin and molded. Whatever the material of the lid, if there is a phosphorescent material adhesion on the upper surface of the lid, the phosphorescent material is adhered to the upper surface of the lid. A typical example of the adhesion of the phosphorescent material is application of phosphorescent paint.

  As shown in FIGS. 1 to 3, the boundary block of the embodiment is installed by arranging a large number of horizontally long block bodies 1 linearly on a road. The boundary between the roadway d and the sidewalk f is shown.

  The roadway d forms a concrete board c on the crushed stone layer s. The concrete board c forms a mortar layer m on the edge of the boundary with the sidewalk f, and the block body 1 is installed on the mortar layer m. The block body 1 of precast concrete is connected to a concrete board c through a mortar layer m.

  The block main body 1 is formed into a horizontally long rectangular parallelepiped shape, an insert 2 for connecting the hanger h is embedded, and the insert 2 is opened on the upper surface. The insert 2 has an upper end surface with an opening flush with the upper surface of the block body 1. After use of the hanger h, the insert 2 is fitted with a stopper-type lid 3 in the opening to close the opening. The lid 3 has an upper surface flush with the upper surface of the block body 1 and is exposed to the outside air.

  The plug-type lid 3 is a synthetic resin molded product and is mixed with a phosphorescent material. The upper surface of the lid 3 is exposed to sunlight in the daytime to absorb the light, and releases the accumulated light at night.

  The insert 2 is formed of a hard synthetic resin such as ABS resin and has a substantially cylindrical shape. Specifically, as shown in FIGS. 4 and 5, the lid fitting portion 11, the shaft insertion portion 12, and the retaining portion 13 are formed sequentially from the top to the bottom. The lid fitting part 11 has a circular center hole. The shaft insertion portion 12 has a central hole with a substantially rectangular long side central portion inflated in an arc shape. The latching portion 13 has a circular center hole. The center hole of the lid fitting part 11, the center hole of the shaft insertion part 12, and the center hole of the retaining part 13 are concentric and communicate with each other.

  The plug-type lid 3 is a molded product of an elastic synthetic resin such as polypropylene resin and has a plug-type shape. Specifically, as shown in FIGS. 4 and 6, a peripheral wall 17 is provided under the circular top plate 16. The peripheral wall 17 is shaped like an inverted conical cylinder with a loose taper, and a plurality of slits 18 are formed in the lower part. The plug-type lid 3 makes it possible to reduce the outer diameter of the peripheral wall 17 and restore it by an elastic force. It is configured so that it can be easily fitted into the lid fitting portion 11 of the insert 2 and is securely fixed.

  The synthetic resin of the molding raw material of the lid 3 is mixed with a phosphorescent pigment of a phosphorescent material. The phosphorescent pigment is made of an oxide mainly composed of alumina such as an aluminate compound.

  As shown in FIG. 7, the hanger hoops the ring portion 21 and the shaft portions 22, 23 up and down. The ring portion 21 has an annular shape into which a lifting wire rope or hook is inserted. The shaft portions 22, 23 are fixed to the lower end portion of the vertical main shaft 22 through a retaining rod 23 that is a horizontal bar. Inverted T-shape. The main shaft 22 is inserted into the lid fitting portion 11, the shaft insertion portion 12 and the retaining portion 13 of the insert 2. The retaining rod 23 is inserted into the retaining portion 13 through the lid fitting portion 11 and the shaft insertion portion 12. When the hanger h is inserted into the insert 2 and rotated 90 degrees, the retaining rod 23 hits the ceiling of the retaining portion 13 and cannot be removed. When it is further rotated 90 degrees, it can be removed.
