Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stone block used for bank protection work and embankment work.

Conventionally, various types of stone blocks have been used, but the method of connecting stone blocks to each other is to locally connect the joint end surfaces of adjacent blocks with bolts at important points. Although the blocks could be stitched together, this only prevented the blocks from separating from each other, but did not allow the joined blocks to form a solid monolith.

In addition, as shown in Tokuseki Sho $-67230,
A structure has also been proposed in which the four corners of the block are cut out to form a forehead slope in that part, and a connecting punch inserted through the front side of the block is fastened with a turnbuckle. Since the joint is in a tension-locked state, it can be bent and cannot be used as a reinforcement joint for a bending resistance member.

In addition, since only blocks in the diagonal direction are joined, the blocks are piled up, and vertically adjacent blocks are not joined. Therefore, there is less resistance to displacement and separation between each plate, and the Tonosho It has the disadvantage that it cannot be made into a grandchild wall sufficient to support it. The present invention relates to a masonry block that easily forms an integrated structure by directly connecting reinforcing bars embedded in each block to each other.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The stone block of the present invention will be explained in detail below with reference to the drawings.

FIG. 1 is a perspective view showing the simplest shape of the diagonal reinforcement plate of the present invention.

FIG. 2 is a partial perspective view showing how the upper and lower stages are joined.

FIG. 3 is an enlarged perspective view illustrating a state in which diagonal stripes overlap each other at both ends and are continuous.

FIG. 4 is a partial perspective view showing a state in which the overlapping portion of the diagonal reinforcement is tightened using a metal fitting.

FIG. 5 is a perspective view showing another embodiment of the diagonal strip.

FIG. 6 is a perspective view showing how the stone reinforcement block of the present invention provided with ribs is being roughened.

FIG. 7 is a cross-sectional perspective view of the construction on a steep slope. The basic structure of the stone block of the present invention is shown in FIG. 1, and its features include a diagonal bar 1 made of a concrete flat plate whose overall outline is approximately a rectangular hexahedron; Intersect within the central vertical axis of the flat plate of the diagonal reinforcement plate 1,
It consists of an upper diagonal reinforcement la and a lower diagonal reinforcement 1, which are two overlapping diagonal reinforcements, and when the diagonal reinforcement version 1 is constructed on a slope etc., the upper end surface lb and the lower end surface lb' have the left and right sides of the end surface length. Make two notches lc at approximately one-fourth of the way from the end face, for a total of 4
The ends of the two diagonal reinforcements are cut so that the diagonal reinforcements protruding from each notch of the adjacent diagonal reinforcement plates are substantially in line with each other, and the ends of each diagonal reinforcement overlap each other. The required joint length is made to protrude from the notch.

The stone block shown in Fig. 5 has a lip structure where only the buried diagonal reinforcements la and la' are thick, and the other parts are made thinner to reduce weight, and the upper and lower end surfaces are provided with ridges lh for horizontal joints. The projecting edges lh' for vertical joints are provided at different levels on the left and right end faces, respectively, in order to prevent the sand and sand from being drawn out.

In this way, when a built-up rib is formed on a flat plate of a block, the rib and diagonal reinforcement work together to serve as a beam for the diagonal reinforcement plate of the block. Next, we will discuss stone cladding construction using this diagonal reinforcement slab.

First, lay out the first level of diagonal reinforcement plates horizontally in a single row on the foundation pedestal, and place the second level of diagonal reinforcement plates so that their vertical center lines are aligned with the lower level of the first level of diagonal reinforcement plates. Lay them out according to the vertical joints. Since each diagonal reinforcement embedded in the diagonal reinforcement slab is embedded in each diagonal reinforcement slab as described in detail earlier, the diagonal reinforcement protruding from the lower end surface of the second stage diagonal reinforcement slab is The diagonal strips protruding from the upper end surface of the diagonal strip are automatically overlapped and continuous on almost a straight line. Figure 2 shows the joined state of the upper and lower stages of the diagonal reinforcement plate shown in Figure 1, and Figure 3 shows an enlarged view of the diagonal reinforcement.
Indicates a state in which the surfaces of both ends are bonded to each other, overlapped, and continuous in a straight line.

In other words, when diagonal reinforcement plates are arranged as shown in Figure 2, the upper diagonal reinforcement la and lower diagonal reinforcement la' of each diagonal reinforcement plate become one continuous reinforcing bar, and these are the mesh reinforcing bars in the integrated plate. becomes. Figure 3 shows how each oblique muscle is aligned in a straight line.For the upper oblique muscle la, the line connecting the center axis d of the upper oblique muscle d and the center point e of the upper gradualus muscle is continuous with the upper oblique muscle above it. The lower diagonal reinforcement la' is also buried in the diagonal reinforcement plate 1 so as to form a straight line f, and the line connecting the lower diagonal reinforcement center point e' forms a straight line f'1 that connects the lower diagonal reinforcement thereon. Ideally, it would be buried in the same way. The diagonal strips are connected to each other around the diagonal strips, such as above and below, or on the left and right, at a distance of approximately one-fourth from the vertical quarter line g of the upper and lower end faces of the diagonal strip 1, that is, from the left and right ends of the end surface length. They overlap each other, and are fastened at this portion using a fastening tool 2, an example of which is shown in FIG. If the upper tier is constructed in the same way, each diagonal reinforcement plate will directly connect the two diagonal reinforcement plates of the upper and lower tiers that are connected to it, and their embedded diagonal reinforcements, and these diagonal reinforcements will automatically join together. , and easily construct a series of reinforcing bars that cover the entire construction surface.

This is also a feature of the technique of the present invention, and by filling the boxed concrete formed by the end face notch of the overlapping diagonal reinforcement section, a large number of diagonal reinforcement slabs are connected and the reinforcement is distributed evenly across the entire surface. An integrated version can be formed.

At this time, if ribs are provided on the diagonal reinforcement plate as shown in Figure 5, the ribs will be placed in a straight line as shown in Figure 6, and the notch will be filled with concrete. Then, since the ribs are continuous in a lattice pattern, it becomes an integrated block with great resistance to bending due to loads applied from a direction perpendicular to the plane of the block, such as a tonosho block. As shown in Figure 7, for steep slopes, increase the lip and
If necessary, it is also possible to build a retaining wall with multiple diagonal reinforcements to support a large tonosho.

The characteristics of the diagonal bar, which is the right-hand block of the present invention, have been described above in terms of its construction method.The effect is that construction is easy and quick, and it is an economical construction method that eliminates waste in terms of materials. In addition, because of its structure, it can strongly resist displacement and separation between the plates due to their own weight and external forces, so there is less risk of them breaking and collapsing in the event of a disaster.
