DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembly of a top type block for a base, in which an inverted cone-shaped body is provided at a lower portion of a flat upper plate, and a shaft leg is provided at a lower center of the body.

[0002]

2. Description of the Related Art A top block is a horizontal block in which uneven settlement is suppressed by balancing the weight of the block itself and the load on the block with the total ground reaction force and frictional resistance generated on the fuselage and axle legs. Due to its excellent mechanical action, it is widely used as a basic component in various soft ground stabilization methods and foundation reinforcement methods.

In the laid state, a plurality of top blocks are arranged vertically and horizontally in a horizontal plane, and the upper reinforcing bar lattice body connected to a suspender at the center of the upper surface of the flat upper plate, and the base of the shaft leg Because it is connected by the lower rebar lattice connected to the part, it is stable and self-supporting, but before laying it is not self-sufficient because the shaft legs disturb and it is difficult to store and transport because it is poorly seated. I have. Special jigs may be provided to stabilize sitting. In addition, in laying, a plurality of top blocks must be embedded in the ground one by one while determining their relative positions correctly, so that there has been a problem that the work efficiency is not good.

[0004] The ground stabilization / reinforced block disclosed in Japanese Patent Application Laid-Open No. H8-74242 proposed to solve this problem includes:
It has a through vertical hole in the center portion, and has a plurality of adjacent inverted cones in its external report centering on the through vertical hole, and the inverted pyramid has a central axis centered on the through vertical hole. It is located at equal intervals on the concentric circles, and forms a panel body continuously at the upper part.In summary, a plurality of top type blocks are integrally formed by connecting the flat upper plate Things.

[0005] However, in the ground stabilizing / strengthening block in which a plurality of top blocks are connected to each other on the flat upper board, stress is concentrated on a connecting portion between the flat upper boards during transportation or installation. There is a high risk of breakage of the connection. If the damage of the connecting portion extends to the torso and the side portion of the torso is largely chipped, the original mechanical action of the top block is reduced. Further, when the connecting portion is broken from the upper surface to the lower surface and is separated from the adjacent top block, the top block must stand alone in an isolated and unassisted state. Naturally, when the top block tilts more than the vertical position, its original mechanical action is greatly reduced.

[0006] If damage to the connecting portion or damage to the body portion is found before the installation, the top block may be removed from the construction, but if such a situation occurs after the installation, the situation may occur. There is no way to check itself, no way to deal with it. If there are many damages or breaks, the effect of ground stabilization and reinforcement will be greatly lost.

[0007]

Therefore, an object of the present invention is to have an autonomous property, so that it is easy to handle during storage and transportation, work efficiency of construction is good, and
An object of the present invention is to provide a top-type block assembly for a foundation that can sufficiently exhibit its original mechanical action because there is no breakage or chipping of the top-type block of each unit due to stress concentration. It is another object of the present invention to provide a top-type block assembly for a foundation, which further increases the strength against a vertical load or a horizontal load.
