Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention is a block for paving roads, plazas, parking lots, gardens, etc.

Conventional technology There are various types of conventional paving blocks in which the joint end faces of each side are linear, concave, convex, and wavy, but in all cases, adjacent blocks are constructed with a constant gap between them. It is considered desirable.
In other words, paving blocks are made by laying sand to a certain thickness on top of a compacted roadbed, filling the gaps between adjacent blocks with sand, and compacting it from the top of the block using a vibrating device. The purpose of filling the joints is to allow rainwater to permeate through the gaps between the joints, and to disperse the force when heavy vehicles pass. Therefore, if the end faces of the blocks are in close contact with each other, not only will the above effect be lost, but if a heavy vehicle is placed on the adjacent face of the blocks, an uneven load will be applied to the joint part due to heavy pressure, and the block itself will be damaged. There is a phenomenon in which the upper surface of the joint is gouged as the surface of the joint is tilted.

In addition, the number of paving blocks varies from 20 to 0 per square meter.
Since it is common for construction to be carried out in combination,
It is mechanically difficult to arrange these at regular intervals, and automation requires quite complicated equipment.

Purpose The purpose is to streamline production by making it easier to assemble paving blocks in advance at a factory, etc., and by mechanizing everything from manufacturing to transportation and construction.

Composition The present invention provides small protrusions for forming a joint width at a position of 2/3 or less of the block height on each side of a mesh-like fiber sheet having a certain size, on the surface facing the adjacent block. What is claimed is: 1. A paving block assembly comprising a plurality of paving blocks provided with a plurality of paving blocks facing each other and adhered to each other with constant joint spacing maintained through the small protrusions.

An embodiment will be described with reference to the drawings. In FIG. 1, numeral 1 indicates a mesh-like fiber sheet, which may be either natural or chemical fiber. A plurality of paving blocks 2 are arranged side by side on this fiber sheet 1 and adhered with, for example, an epoxy resin adhesive. Small protrusions 3 are provided on each side of the paving blocks 2 at necessary locations, and a predetermined joint width is provided between the paving blocks 2.

After the adhesive has hardened, the paving block assembly thus formed is lifted from both ends with hanging tools 4, as shown in Figure 2, and stacked at a predetermined position in preparation for shipping. sheet 1
is curved. At this time, the distance between the paving blocks 2 is properly maintained by the small protrusions 3, and the corners of the upper ends of the blocks do not come into contact and be damaged. Furthermore, there is no risk of damage when transporting this to the construction site and suspending it for construction.

FIG. 3 is a plan view of an example of a single paving block 2 according to the present invention, and FIG. 4 is a front view thereof. Small projections 3 are provided at predetermined locations on each side of the paving block 2. The small protrusion 3 has a thickness corresponding to the joint width, and its height is less than 2/3 of the height of the entire paving block 2. When the height of the small protrusion 3 exceeds 2/3 of the height of the entire block,
The flexibility during lifting and hanging is lost, which is undesirable.

Such paving blocks 2 may be directly adjacent as shown in FIG. 5, or may be staggered and adjacent as shown in FIG. 1. In either case, each small protrusion 3 does not directly face each other, and it is preferable that there are two or more small protrusions 3 on one side so that the joint gap can be maintained stably. By making the top surface of the small protrusion 3 an inclined surface, the movement of the paving block 2 when suspended can be made smooth.

Although the shape of the paving block 2 is not limited to the above embodiment, it is more effective to have a side surface shape as complicated as possible.

Effects By placing the paving block assembly of the present invention on the ground as it is, it is possible to form paving sections with a constant joint width without worrying about the placement of individual paving blocks. It is easy to do, and by appropriately connecting them, it is possible to easily pave a wide range by only considering the joint width of the joints.

Another advantage is that the assembly can be lifted and suspended without damaging the paving blocks.

In addition to holding the paving blocks together, the mesh fiber sheet allows joint material and ground material to flow freely through the mesh.
Stabilize the laying condition of paving blocks.

The single paving block of the present invention is effective in making such an aggregate.
