Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a boundary block used to separate a sidewalk and a roadway.

[Prior art and its disadvantages] As shown in FIG. 5, the conventional boundary block has the following characteristics:
Since the structure is such that the blocks having the boundary part 02 integrally formed in the center of the upper surface of the base board 01 are arranged horizontally in a row, the following drawbacks occur.

a The edge of the constructed boundary, as shown by arrow a in Figure 5, is a sharp end face of the boundary block that stands out as it is, which is dangerous for pedestrians, bicycles, etc., and is dangerous when hit by the wheels of a car. The impact the block receives is huge.

b. Because mortar is inserted and added to each piece one by one, construction is time-consuming and labor-intensive.

c Boundary blocks repeatedly expand and contract due to changes in temperature, but the conventional structure in which mortar is inserted and added does not absorb this expansion and contraction.

[Purpose of the present invention] The present invention is proposed in view of the above points.
The first objective is to propose a boundary block that is safe for pedestrians and bicycles and that causes less shock when hit by automobile wheels.

Furthermore, the second objective is to propose a boundary block that can be constructed in about 1/3 of the time and labor required by conventional methods.

A third objective is to propose a boundary block that effectively absorbs the expansion and contraction effects caused by changes in temperature.

[Configuration of the present invention and its operation] In order to achieve the above object, the present invention proposes a boundary block having the following configuration.

An end block with one end rounded and the other end formed in a vertical plane in the longitudinal direction of the center top surface of the base board, and a boundary part with both ends formed in a vertical plane in the longitudinal direction of the top surface of the base board. and an intermediate block formed by placing the intermediate block in the middle and arranging the end blocks in a straight line on both sides of the intermediate block, inserting a cushioning material between the intermediate block and the end block, and inserting a cushioning material between the intermediate block and the end block. A boundary block formed by integrally connecting a block and an end block with a connector.

The above-mentioned boundary blocks are constructed by connecting intermediate blocks and end blocks integrally at a factory and transporting them to the site, or by connecting them at the site.

[Embodiments and their effects] Fig. 1 is an exploded perspective view of a boundary block according to the present invention, in which 1 shows a boundary part 4 with a rounded edge 2 at one end and a vertical surface 3 at the other end as a base board. This is an end block integrally formed in the longitudinal direction at the center of the upper surface of 5.

Reference numeral 6 designates an intermediate block formed by forming a boundary portion 8 with vertical surfaces 9 at both ends in the center longitudinal direction of the upper surface of the base board 7.

Reference numeral 10 denotes a water passage hole which is provided to pass through the intermediate block 6 in a transverse direction, and this water passage hole 10 may also be provided on the end block 1 side.

FIG. 2 shows the end block 1 and intermediate block 6 as shown in FIG.
4, and 12 is a cushion material such as sponge or rubber inserted between the vertical surfaces 3 and 9 of the end block 1 and the intermediate block 6 during this connection.

Although there is one intermediate block 6 in the above embodiment, two or more intermediate blocks 6 may be connected between the end blocks 1. Furthermore, the end block 1 may terminate with an intermediate block 6 if unnecessary at its end.

[Effects of the present invention] As described above, the present invention connects the end blocks and the intermediate block together with a cushion material interposed,
By implementing this, we can expect the following effects.

a) The rounded end blocks make it difficult for pedestrians to trip, and even if they trip or get hit by a bicycle wheel, the impact is minimal and safe. Furthermore, even if the boundary block is hit by a car wheel, the impact is small and there is little risk of damage to the boundary block.

b The end blocks and intermediate blocks can be connected at the factory with a cushion material interposed between them, and then transported to the site for construction, which reduces the labor and time by about 1/3 compared to the conventional method of constructing each block one by one. can be saved.

c. Since the cushion material is interposed between the end block and the intermediate block, the shrinkage of the boundary block can be absorbed by this cushion material. As a result, there is no need to worry about gaps forming within the boundary block due to changes in temperature, or the boundary becoming bent or damaged due to expansion.
