Abstract

PURPOSE:To make the installation position of sidewalk blocks accurate and perform the solid installation by carrying out the construction of sidewalk by using large sidewalk blocks which also serve as boundary blocks between sidewalk and roadway. CONSTITUTION:A plural number of large sidewalk blocks which also serve as boundary blocks between sidewalk and roadway are prepared. Also, the sidewalk blocks are provided with various functions by providing slope in advance or Braille dots for the blind. The sidewalk face and the boundary face between sidewalk and roadway are integrally formed by combining a plural number of sidewalk blocks. For example, an inclined block 3 for descending from high floor sidewalk on roadway is installed at a crossing of crossroads. A square block 2 and a block with Brailled dots 4 are arranged on the right and left of the inclined block 3. Mortar is poured into joint parts of each block through mortar flow-in opening 16 to solidify the sidewalk.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a sidewalk block which is used as a boundary block and is used as a highway or lowbed sidewalk and a bed for flower beds.

[0002]

2. Description of the Related Art Conventionally, pavement ground was first constructed and road 2
2, a boundary block 20, to establish a boundary between the sidewalk and
The ground is solidified by the crusher run 25, etc. at the installation location of, and then the underfill concrete 24 is placed, and after hardening, the boundary block 20 is installed at a predetermined height, and one boundary block 20 is installed and the boundary mortar and joint mortar are used as boundaries. In the case of a high-floor sidewalk, the sidewalk width was set to a predetermined level and crushed with a crusher run 25, etc. and then paved with concrete and asphalt. In this case, in the case of asphalt pavement, it is particularly hardened with a vibrator, etc., but the details of the installation in every corner were incomplete because the vibrator could not be used, and it was also difficult to finish the sloped part of the entry part from the roadway. In the case of laying a sidewalk block 17 such as interlocking, which was a construction process and has deteriorated aesthetics, a crusher run 25, etc. after sanding sand 26, is laid and the block is laid with a vibrator etc. Then, the height was adjusted and laid again with a vibrator or manually, and in this case, it is laid and pasted on the entry part from the roadway in the same way as above, but it becomes a more incomplete construction and the sidewalk block 17, Since the block itself has a flat surface, the larger the surface area of the block, the more curved the flat surface of the slope and the sidewalk and the curved surface of the block. Since convex protrusion pavement surface because part protrudes is formed pedestrians, there have been cases particularly dangerous for people blind.

In addition, since the lower part is a sandy layer when laying down, the sand 26 flows due to permeation of rainwater etc., the block 17 falls, and it becomes an uneven sidewalk surface and the influence becomes great with the passage of time and it needs to be reworked. I came. Braille block for blind people, point block 19, direction block 1
No. 8, however, the rectangular blocks like the conventional ones are laid unevenly on the boarding portion and the like, which impairs the appearance. As mentioned above, many sidewalk constructions were carried out by human resources, and there were many defects after completion.

[0004]

[Problems to be solved] Conventional sidewalk block 17,
In the construction of, the boundary block 20 can be installed, hardened and fixed first, and then the roadway and the sidewalk can be constructed as shown in FIGS. 2 to 3. However, since the boundary block 20 is longer than the width, It was unstable and there was a lot of history of constructing sidewalk work after the roadway construction was over, so it was sometimes impossible to proceed at the same time. Also, as seen in the planes of FIGS. 2 to 4, the curved portion of the slope of the entry portion from the roadway to the sidewalk is very difficult to lay the asphalt and interlocking pavement blocks 17, and it takes time. The embedding of braille blocks for the blind is also very complicated and impairs the aesthetics of the finished surface.Because both sidewalks are narrow sidewalks, handwork is mainly used.Since the ground is sandy ground, it is washed away by rainwater etc. As described above, there were many defects that induced unevenness and the like.

[0005]

Most of the above-mentioned drawbacks require instability and a lot of trouble because one unit is small in all of the boundary block 20 used, the sidewalk block 17, etc. Although it required a technique to install it accurately, it was incomplete and caused many deformations and irregularities. Therefore, one unit was enlarged and one block was installed to simplify a large area. It can be installed accurately and firmly, and when constructing a sidewalk, it is always on the side of the road so any large machine can be used sufficiently, so it is necessary to use a block as large as possible. Yes, it can be simplified in terms of production and loading and unloading, and can greatly save labor in installation and construction.

[0006]

As described above, by using the block of the present invention as shown in FIG. 1, which has a large unit block and various functions, it is possible to construct easily and complete a strong sidewalk. First, in order to simplify the sidewalk block of the present invention, as shown in FIGS. 4 to 5, the boundary block 20 and the sidewalk surface are integrally molded, and one unit is enlarged into each type for factory production. Since it is large and simple in factory production, it has good productivity and can be loaded and unloaded on trucks without the need for pallets. In the field as well, unloading can be simplified by using a wrecker, etc. 2 to FIG. 3 are conventional construction methods, and first, the boundary block 20 is first mounted on the leveling ground, the Kuriishi ground work, and the underfill concrete is hardened and the boundary block 20 is mounted. Place and install the mortar by adjusting the top, bottom, left and right with the mortar etc., and after hardening, connect the joints of the blocks with mortar and finish the joint with a trowel etc. At this point, it also serves as a make-up, so it requires a great deal of skill and human resources, and its superiority and inferiority after completion is evaluated. Next, in order to fix the boundary block, the sidewalk will be temporarily backfilled and roadway construction will begin. As soon as the carriageway is completed, sidewalk construction will be started.

[0007] The sidewalk has a narrow detour width, and there are many drawbacks as mentioned above due to various shapes such as slopes, crossroads, three-way intersections, roadways, pedestrian crossings, flower beds, etc. It was A comparative explanation will be given to the on-site loading and unloading and installation work when the present invention sidewalk block is used. First, since the unit block is large, production and loading and unloading are easily operated as described above, and even in installation work. Even in the Kuriishi area, it is a wide area and the average land leveling is easy. As shown in Fig. 4 to Fig. 5, the front and rear width of the sidewalk of the car is wide and the area is wide. It can be installed simply by operating the four corners of the block.In addition, even if there is no underfill concrete in advance, it can be easily installed by pouring fresh concrete onto the surface of a crushed stone and adjusting it with a wedge. If so, install mortar and install it in the same way.

Since all the blocks are of the same unit, they are sequentially installed in the same process, that is, the installation process is the same for circulars, squares, flower beds, etc. at the intersections, which can be installed easily and accurately. . In addition, since the weight is a little heavy, it has good stability and can work simultaneously with the roadway.Once the installation is completed, the complete work is completed without the need to change fluctuations due to rainwater etc. and narrow and thin manual work at a later date. I can do things. In addition, because the Braille block for the blind is also integrated, it is possible to give it a beauty that could not be seen in the past.
In addition, since the independent block for the blind is also long and rectangular, it has a large unit area and is easy to install.

[0009]

[Embodiment 1] Although the basic shape of the present invention has been described with reference to FIG. 1, this block will be described with reference to FIG. 9 and a plan view of a flowerbed portion. As described in [claim 3], when planting trees or the like, the left and right semi-circular blocks 11 and 12 are installed so as to face each other to make circular planting points appear, and low trees such as azaleas and If you want to make a long space for flowers on the border of the roadway, install semi-circular blocks 11 and 12 at both ends, and the middle part is several intermediate blocks 1 according to the length.
The purpose can be achieved by installing 3. By installing a normal block 1 on the sidewalk that does not require planting, the installation can be completed with a simple shape. A braille block 19 for the blind and a sidewalk block 17 are laid to complete the space. At this time, since the mortar inflow opening portion 16 for fixing the position is formed in the joint portion of each block, the mortar is inserted at the same time when the block is placed and hardened to maintain a strong sidewalk. Complete as shown.

[0010]

[Embodiment 2] This FIG. 6, a plan view, is a crossing road, which is a place for getting on a high-floor sidewalk from the direction of a crossroads. It can be processed by installing an inclined block 3 that descends to. At this time, the slanting block is constituted by a combination of the right and left rectangular block 2, the slanting block 3, and the slanting Braille block 4, and the entry portion is completed. Also, because it is a crossing intersection, a corner block 5 can be installed at the corner of the sidewalk to ensure a level difference with the roadway, and at the same time, the boundary and sidewalk can be finished with a beautiful appearance. Of course, the entire side of the corner is completed by laying the sidewalk block 17 along with the Braille block 19 for the blind, the direction block 18, etc. on the sidewalk. Boundary block 2 at the same corner and entry point by the conventional method
0, a sidewalk block 17, and a blind person block 19 were combined, but the contact point between the sidewalk surface and the inclined surface was complicatedly curved, so a smooth road surface was not possible and the appearance was uneven. It was also dangerous because it had the drawbacks of not only damaging but also forming a protrusion.

Further, since the circular portion of the corner portion is in contact with the inner surface of the circular boundary block 20, the sidewalk block 17 is cut into a circular shape and laid so that no gap is formed, which is a great labor burden. Was needed. There was also the drawback of becoming uneven as it ages. By using the block of the present invention, the side of the corner block 5, which is a curved corner portion, on the sidewalk is formed in a straight line with the short sides of the trapezoid.
Since the sidewalk block can be cut only by straight line cutting, it is a simple operation that saves labor, and since the border and sidewalk are integrated and enlarged, the laying area of the sidewalk block 17, etc. is reduced, so the construction period is also reduced. A corner sidewalk that is both shortened and strong and has a beautiful appearance can be completed.

[0012]

[Third Embodiment] FIG. 7 shows a case where there is no sidewalk at the crossroad intersection at the crossroad intersection where the crossroad is connected to the main road from a one-way one-way vehicle alley as in [Second Embodiment]. In this case, the construction of the sloped entry portion toward the main road is completed in the same manner as in [Example 2], but since the entrance to the sidewalk on the side of the one-way alley is a corner, the inclined block 7 formed in a circular shape, Since it has to be connected to the sidewalk using the road surface, it is completed by combining the circular left and right end slant blocks 6, the slant center block 7, the slant braille block 8, etc. The comparison with the construction method is the same as above, and a simple and strong boarding sidewalk can be completed.

[0013]

[Embodiment 4] This FIG. 8 is used for a crossroad intersection as in [Embodiments 2 and 3], and it is a stilt walkway that reduces the difference in level with the roadway before reaching the main road side and alley side crosswalk. It is possible to move to each pedestrian crossing by moving to a low-floor sidewalk by installing sloping blocks 9-10, and since the low-floor sidewalk is composed and connected from both sides, one road up and down will cross both roads. I can do things. At the corner, since the sidewalk has a small height with respect to the roadway, it is necessary to protect it by the boundary block 20 so that the vehicle does not enter the low-floor sidewalk. Also from the alley, it is necessary to similarly install and protect a boundary block 20 on a part of the main road side, that is, between a part of the pedestrian crossing on the main road side. Construction and effect are [Example 2
3].

[0014]

[Embodiment 5] The sidewalk is accompanied by excavation work and burial work for a part of the sidewalk to install rainwater, domestic drainage, gutters of sewers, etc. The purpose can be achieved by providing a detachable detachable block 14, and by arranging the left and right sidewalk blocks symmetrically with steps and protrusions as in [Claim 6]. . This part needs to be installed at several places on the sidewalk, and this block does not require joints 16 for mortar insertion.

[0015]

As described above, the conventional boundary block 2 is used.
When using 0 and sidewalk block 17, the unit is small and the process is complicated, so the consumption of human materials is large but the finish is uneven, and it changes and deforms over time, which is a dangerous sidewalk surface. There was a flaw that also impaired aesthetics.
Of course, the same applies to the asphalt sidewalk, which requires repair. By utilizing the sidewalk block of the present invention, the above-mentioned drawbacks are eliminated. That is, since all blocks are enlarged, first of all, in terms of production, it can be easily produced by using various large formwork, and at the factory and on-site loading, field piles can be stacked by lifts and wreckers and pallets by human work. Since it does not use, etc., it is simplified and labor saving by using mechanical force for both loading and unloading. At the site, the unit block is large as described above, so the installation is done by finely adjusting the four corners of the block based on water thread etc. to maintain the accuracy in millimeter units. As well as doing so, a strong sidewalk can be completed by pouring mortar 16 into the joint and inserting and hardening it. It has a large unit weight, a large footprint, and a stable and strong sidewalk.

Since it is a large block, most of the sidewalk surface can be laid by installing one block. Therefore, the remaining space is reduced by laying a block for the blind and the remaining space is reduced. 17 and so on. Since all of the sidewalk blocks 17 are laid in a straight line, they can be easily accommodated, which saves labor and can be completed easily. In addition, because the sidewalk block 14, which is removable to enable sidewalk excavation and burial, is prepared and used for laying pipes for rainwater and domestic drainage, all construction can be completed easily and after completion. It is also possible to excavate and provide a strong sidewalk. If the unit block is large and heavy and there are defects in transportation etc., it will be reduced by forming a recess in the center of the back surface of the block to eliminate the volume, and the weight will be lighter and the defects can be reduced. . By reducing this, there is no problem in strength and construction, and since the weight is lighter, it is advantageous for transportation, installation, etc., and labor is saved.
