Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a block-shaped concrete block and a method for installing the same.

BACKGROUND OF THE INVENTION Conventionally, frame-shaped concrete blocks have been proposed as goring stones for civil engineering, architecture, and machine foundations. This is a block-shaped block body and a shaft leg integrally molded from concrete, and has the effect of distributing the direct load laterally by the action of the conical surface of the block body.

Problems to be Solved by the Invention However, with such conventional block-shaped concrete blocks, centering (determining the installation position) is difficult, especially since the weight of the block body is large. There is a problem in that it is difficult to level the top surface of the device, making installation work difficult.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to solve these conventional problems and improve installation workability.

Means for Solving the Problems In order to solve the above problems, the present invention has a top-shaped block main body and a pivot leg that are configured to be detachable.

Further, in the method of the present invention, after the pivot leg is driven into a predetermined position in the ground, a top-shaped block body configured to be detachably attached to the pivot leg is attached to the pivot leg.

Operation According to such a means, it is sufficient to first securely position only the pivot leg at a predetermined position, adjust its vertical axis correctly, drive it into the ground, and then attach the block body to the pivot leg. In this way, the positioning and leveling of the entire concrete block can be carried out by adjusting only the small and lightweight pivot legs, making the installation work of the entire concrete block easy and accurate.

Examples Examples of the present invention will be described below. 1st
Figures a, b, and c show an example of a block-shaped concrete block 1 according to the present invention, where 2 is a block body having a conical surface 3, and 4 is a pivot leg. The block main body 2 has a downwardly expanding tapered hole 5 formed therethrough on its central axis, while the shaft leg 4 has a tapered portion 6 that fits into the tapered hole 5, so that the two can be connected to each other. are detachable from each other. FIG. 1c shows a state in which the pivot leg 4 is inserted and fitted into the block main body 2 and integrated. Reference numeral 7 denotes a handle of the block body 2, and a portion buried in the block body 2 acts as a reinforcing bar. 8 is a reinforcing bar of the shaft leg 4. The tip shoe 9 of the shaft leg 4 is made of iron or plastic, and the reinforcing bar 8 is attached to its inner surface.

In FIG. 1, both the tapered hole 5 and the tapered portion 6 are shown as having circular cross sections, but they may have other shapes, for example, as shown in FIG. 2, they may have rectangular cross sections.

3a, b and c show other examples of the block-shaped concrete block 1 according to the present invention. Here, in a, a straight hole 10 is formed in the block body 2, and a stepped shaft portion 11 that engages with the block body 2 is formed in the shaft leg 4. Further, in b, a wooden shaft leg 4 is used, and a crossbar 12 is provided for receiving the load of the block body 2 and determining the height position. Furthermore, in c, an iron cylindrical body 13 is buried in the center of the block body 2, and the shaft leg 4 is constituted by a pipe that is fitted inside this cylindrical body 13. Note that the cylindrical body 13 and the shaft leg 4 can be welded together if necessary, and 14 is the welded portion.

Next, a method of installing the above-mentioned block-shaped concrete block 1 will be explained based on FIG. 4. First a
As shown in the figure, the ground 15 is excavated and a mark 16 is marked at the installation position of the block-shaped concrete block 1.
Reference numeral 17 indicates a water penetration installed horizontally to serve as a reference in the height direction, and reference numeral 18 indicates a water pile. Next, as shown in b, the shaft leg 4 is driven into the ground at the mark 16 position. At this time, it is necessary to accurately position the pivot leg 4 in accordance with the mark 16 and to align the pivot leg 4 vertically, but since the pivot leg 4 is small and lightweight, these tasks can be easily performed. be able to. The driving amount of the shaft leg 4 is set to such an extent that the taper portion 6 protrudes from the ground surface.

Once the pivot leg 4 has been driven in, the block body 2 is then attached to the pivot leg 4 as shown in c. At this time, since the positioning and vertical alignment of the pivot leg 4 are ensured as described above, the block body 2 is accurately installed in a predetermined position, and its upper surface is also well leveled. When the installation of the block body 2 is completed, the cut gravel 19 is filled as shown in d, and the installation work is completed.

FIG. 5 shows a plan view and a front sectional view of the above-mentioned installed state.

As described above, according to the present invention, the block-shaped concrete block 1 can be installed easily and accurately.

Another advantage is that the length of the pivot leg 4 can be freely selected depending on the conditions of the ground 15 and the superstructure. That is, FIG. 6 illustrates the case where the frame-shaped concrete block 1 is used as the foundation of the retaining wall 20, where a is a front view thereof and b is a cross-sectional view taken at a. Here, the pivot leg 4 at an appropriate location
By forming a relatively long, the horizontal earth pressure 21
It acts as a pile to receive the load, thereby preventing it from slipping. FIG. 7 illustrates the case where the frame-shaped concrete block 1 is used as a stone for a building, in which a is a front view thereof and b is a cross-sectional view taken at a. In this example, the long shaft leg 4a
By arranging them appropriately, it is possible to obtain the merging action of the chestnut stone and the pile, and the shaft leg 4 that acts as a pile can be obtained.
By increasing the frictional force due to a, the effect of increasing the supporting force of the loaded load can be obtained. In this way, by using the longer shaft leg 4a, the function as a stake can be more clearly provided.

Furthermore, the block body 2 is easier to manufacture than the conventional one in which the shaft legs are integrally formed, and when storing it, it can be stacked vertically, so it does not require a large space and can be arranged in an orderly manner. In addition, there will be no damage during storage or transportation.

Effects of the Invention As described above, according to the present invention, the block can be installed easily and accurately, and the installation work can be performed well. By freely selecting the length of the structure, the direct load and horizontal force acting on the structure can be rationally borne.
