JPH09256344A - Both-face block - Google Patents

Abstract

PROBLEM TO BE SOLVED: To increase the strength, by integrally forming the hexagonal front face part and the hand drum-shaped rear face part. SOLUTION: This both-face block is constituted of a hexagonal front face part and the rear face part in which respective shapes divided from the hexagonal upper top to the lower top are exchange to the right and left sides to form a hand drum-shape, which are integrally formed. These blocks are stacked, respective side faces of the hexagonal bodies in the front face part of the block and the hand drum-shaped corners of the rear face part mesh with adjacent blocks positioned in the upper and lower sides, the right and left sides, and the diagonal sides and hence, the whole structure forms a unit. When required, the blocks are prolonged at the front and rear ends to form a large and heavy material and used for a revetment work. And also since it is hard to peel off the blocks, these are used for a heat-insulation material at a curved face part. In this way, the resistant force can be reinforced against external forces and as it is a honeycomb structure, external forces are evenly dispersed. When constructing an earth-retaining wall, it can be assembled in a low cost without other members.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to blocks or tiles used for revetments, retaining walls, walls, outer walls or pavements.

[0002]

2. Description of the Related Art Conventionally, blocks or tiles used for revetments, retaining walls, fences, outer walls or pavements are basically simply piled or spread, as represented by square blocks. Since it has only the shape of the block, it is not sufficient as a means for increasing the strength of the entire structure by engaging the blocks with each other. In order to prevent the block from moving due to an external force such as earth pressure, a plurality of members are required for construction such as fixing the block to the retaining wall with anchor bolts. Providing an uneven part on the upper surface of the block,
It is also known that the upper and lower blocks that are stacked can be fitted together, but it is not sufficient as a shape that fits diagonally in the vertical and horizontal directions.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to ensure that a structure using blocks has sufficient strength against external forces not only in the vertical and horizontal directions but also in the diagonal direction. The purpose is to provide a double-sided block that will be engaged with each other depending on the shapes of the front surface portion and the rear surface portion.

[0004]

According to the present invention, the front surface portion (1) is formed in a hexagonal shape, and the rear surface portion (2) is divided into upper and lower apexes of the hexagonal shape, and the shape is changed to left and right. That is, it is a double-sided block formed in a drum shape, and the front surface portion and the rear surface portion are integrally molded. As a result, when the blocks are stacked and constructed, the front part of each block has a honeycomb structure, and the blocks located in the up, down, left, and right diagonal directions in the rear part are engaged with each other in a wedged manner. Each block constitutes a structure while maintaining closeness as a whole.

When it is used for a wall, it may be possible to arrange the bar by providing through holes in the vertical direction of the block.

[0006]

The present invention is a double-sided block in which the front surface portion (1) is formed in a hexagonal shape and the rear surface portion (2) is formed in an hourglass shape, and the front surface portion and the rear surface portion are integrally molded. As a result, when the blocks are stacked, the hexagonal side surfaces of the front portion (1) of the blocks located in the diagonally upper, lower, left, right directions are in close contact with each other and the rear surface formed integrally with the front portion (1). The corners of the hourglass shape of the portion (2) also come into close contact with the blocks positioned in the up, down, left, right, and diagonal directions and are in mesh with each other. Therefore, when the blocks are stacked, the entire structure is integrally formed. Moreover, since the front surface of each block has a hexagonal shape, the external force is likely to be evenly distributed.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

Example 1 The front surface portion (1) is formed in a hexagonal shape, the rear surface portion (2) is formed in an hourglass shape, and the front surface portion and the rear surface portion are integrally molded.

When the blocks are stacked, the blocks located diagonally in the vertical and horizontal directions are in mesh with each other.

[0010]

When the blocks according to the present invention are stacked, as shown in FIG. 3, the blocks located in the up, down, left, right, and diagonal directions are in mesh with each other and have strength as an integral structure. The resistance of the entire structure to external forces such as earth pressure can be increased.

Since the front portion of the block according to the present invention has a hexagonal shape, when the blocks are stacked, a so-called honeycomb structure is formed, which is advantageous compared with a rectangular shape for evenly distributing the external force. is there.

Since the rear surface portion of the block according to the present invention has a wedge shape in the four corner directions, the stacked blocks are sufficiently meshed with each other and the structure as a whole is maintained in a stable state.

By making the front part and the rear part long and making them large in size as a whole, it is possible to use them as a harbor material that requires considerable strength such as revetment work.

Since it is difficult to peel off due to mutual engagement, it is also useful as a shape of a heat insulating material attached to a curved surface.

The block according to the present invention has a front surface portion and a rear surface portion that are bilaterally symmetrical and has a relatively simple shape, and therefore is easy to manufacture.

When the block according to the present invention is used to construct a retaining wall or the like, it is not particularly complicated and requires other members, so that the cost required for assembly can be reduced.

Since the front surface of the block according to the present invention has a hexagonal shape, the appearance of the entire construction surface can be made excellent.
