Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a construction block used as a foundation material for civil engineering or a construction block.

[Prior Art] Various concrete blocks are known as construction blocks, and generally have a structure in which a large number of blocks of the same shape are connected horizontally or vertically.

In this type of construction blocks, the strength of the structure is maintained by stacking each block while bonding it with cement or the like, and by connecting each block with reinforcing bars.

[Problems to be Solved by the Invention] The conventional construction method described above requires a large amount of work on site, takes time to construct, and requires time and effort to disassemble and move the construction once it has been constructed. , it is also difficult to reuse blocks.

For this type of construction block, it is essential to have sufficient strength for safety reasons, and simplifying construction and reusing blocks conflict with this requirement.
This is a difficult task to achieve.

Conventional building blocks are known to have joints shaped to fit into each other, and to enable rapid construction while fitting these joints; however, conventional blocks of this type requires dimensional accuracy in the shape of the joint, and the direction of the block is restricted, such as by forming a convex part on one end face and a concave part on the other end face, so this should be taken into consideration during construction. However, since the combinations are diversified, it is necessary to prepare many types of blocks at corners and ends.

The present invention solves the above-mentioned problems of the conventional technology, and although it is easy to construct and can be constructed in a short time, it can obtain sufficient strength, and can be disassembled and moved, making it suitable for temporary construction. The purpose is to provide blocks for

[Means for Solving the Problems] In order to achieve the above object, the present invention forms a joint cross section of a block in an uneven shape with respect to a virtual joining plane in a direction orthogonal to the block connection direction, and Both ends thereof terminated within the above-mentioned virtual joining plane, and the shape was symmetrical with respect to the center of both ends.

The most desirable uneven shape is such that triangular depressions and protrusions are formed with respect to the virtual joining plane.

A typical block shape is a block whose basic shape is a rectangular parallelepiped, and whose opposing end faces serve as joint surfaces.

In addition, as a block particularly suitable for a part of a corner, it is also possible to form the block so that two virtual joining planes are perpendicular to each other.

Each block is connected by providing recesses at the upper and lower ends of the blocks at both ends of the uneven shape to form a series of spaces between consecutive blocks, and by fitting a connector into the space. , fix consecutive blocks.

Preferably, aggregate having internal threads at both ends is buried between the recesses at the upper and lower ends, and the aggregates of the upper and lower blocks are screwed to the connector, so that the aggregate is continuously fixed across the upper and lower blocks. to be done.

[Function] In the present invention having the above configuration, since the uneven shape of the joint cross section is formed in a point symmetrical shape, the two joint cross sections in one block have complementary shapes, and
Unlike blocks in a fitting relationship where one joint part is a convex part and the other joint part is a concave part, both joint parts have the same shape, so there is no need to consider the direction of the blocks when joining. Furthermore, since the joining shape is uniform, the types of blocks at the corners and ends do not vary.

In addition, since both ends of the uneven shape are terminated within the virtual joining plane in the direction perpendicular to the connecting direction of the blocks, the joining surfaces facing each direction in the horizontal direction along the virtual joining plane This will necessarily exist, and the horizontal movement of the two blocks joined to each other will be restricted.

In addition, if one block is formed so that the two virtual joining planes are orthogonal to each other, it can be used as a part of a corner block, or by combining four of these on a plane and further stacking them, it can be used as a column. However, in the conventional mating structure, it is necessary to insert the block directly in front and at right angles to the joint surface.
It was difficult to finally join some blocks at the corners. However, according to the block of the present invention in which the concave portion and the convex portion are triangular, it is possible to join even from an oblique direction, so it is easy to join a part of the corner, and it is also easy to construct the block as a columnar body.

Furthermore, since the recesses provided above and below the blocks at both ends of the uneven shape form one space between blocks that are continuous in the horizontal and vertical directions, a box-shaped connector, for example, can be fitted into this space. By screwing this box-shaped connector to the aggregate buried in the block with bolts, etc.,
It can be made into a strong structure connected horizontally and vertically. This connection is made using the upper and lower ends of the aggregate;
Since it does not place any load on the concrete, it can be strongly fastened, and it can be released by removing the bolts without causing the concrete to collapse, so it is possible to disassemble the structure and reuse the blocks. .

[Embodiment] Fig. 1 is a plan view showing an embodiment of the construction block of the present invention, and Fig. 2 is a side view of the same embodiment.

This block ■0 has a length of 9Qcm, a height of 90cm, and a width of 6
0cm is a large concrete block whose basic shape is a rectangular parallelepiped, and its opposite end face in the long plane direction is a virtual joining plane 12.
．． Joint parts A and B are formed as 14. Since the joint portions A and B have exactly the same shape and overlap when the block 10 is reversed, only the joint portion A side will be described in detail.

The planar shape of the joint A shown in Fig. 1 is 2 on the virtual joint plane.
It has a point-symmetrical shape with respect to the center 16 of
It's within. Therefore, the convex portion 22 protruding from the virtual joining plane 12 and the recessed portion 24 recessed from the virtual joining plane 1.2 form complementary triangles.

The uneven ends 18 and 20 of the joint A are located slightly inside the end of the virtual joint plane 12, and the side ends of the joint A are flush with the virtual joint plane 12. A pair of rectangular recesses 26 and 28 are provided at the upper and lower ends of the joint side end.
are formed, and together with the rectangular recesses 30 and 32 of the joint part B, a total of eight rectangular recesses are formed. A reinforcing bar 36 having a female threaded portion 34 at its end is buried between the pair of upper and lower rectangular recesses 26.28 and 30.32. It's open.

Reference numeral 40 denotes a hollow portion, and although not shown in the drawings, a wire mesh material is embedded inside the surface of the block 10 to provide strength.

The rectangular recess 26 forms a series of spaces 42 with the opposing rectangular recesses 30 of adjacent blocks, as shown in FIG.
Rectangular recess 28.3 on the lower side of the block further stacked on top
Together with a series of spaces 44 formed by 2, a rectangular space is formed. A box-shaped connector 46 is fitted into this rectangular space, and a bolt 50 is screwed into the female threaded portion 34 of the reinforcing bar 36 through the hole 48 of the connector 46.

In addition, in the case of the uppermost block, a connector having a shape with half the height and having holes 48 only on the lower side is used.

As shown in the horizontal sectional view of FIG. 4, the depth of the connector 48 is slightly smaller than the depth of the space 42, 44, and after tightening the bolts, the lid 50 is fitted. Make sure the outside surface is even. With this configuration, the outer surface can be made flat with no irregularities, and if mortar is applied, the joints can be made completely invisible. Alternatively, if the outer surface of the lid 50 is configured to be slightly retracted from the block surface and an exterior material such as mortar is embedded in this portion, it is possible to create a joint through this portion.

FIG. 5 shows the assembled state of the building blocks of the present invention,
A mode in which the block 10 described above is combined with an end block 60 and a corner block 70 is shown. The end block 60 has a joint part only on one end surface in the longitudinal direction, and the corner block 70 has two joint parts formed so as to be perpendicular to each other.

FIG. 6 shows a modified embodiment of the block of the present invention, and this embodiment has a convex portion 54 extending longitudinally on the top and bottom surfaces of the block 10a, and a concave portion 56 shaped to fit with the convex portion 54.
It has been established. If formed in this way, the structure will have higher strength against forces acting from the sides of the structure.

FIGS. 7(a) to 7(f) are plan views showing various forms and examples of combinations of the blocks of the present invention, and as shown in the figures, various forms of structures can be constructed.

Since the blocks of the present invention have the same joint shape, a variety of combinations are possible with fewer types of blocks.

Note that the uneven shape of the joint section of the block of the present invention is not limited to a triangular shape, but can also be a smooth curved surface such as an S-shape. In addition, the use is not limited to fences,
In addition to spacing, it can also be used as a block for bank protection and as a foundation material for civil engineering.

[Effects of the Invention] As explained above, in the construction block of the present invention, the cross-sectional shape of the joint part is point symmetrical, so that when the blocks are constructed in succession, the shapes of the front and rear ends of the intermediate blocks are the same. Since there is no need to consider the front-rear direction, construction work becomes easier, and only one type of end block is required. In addition, this cross-sectional shape has sufficient resistance to forces from the side of the block, and when joining, it is possible to join not from directly in front of the joint surface but also from an oblique direction. This is advantageous in the case of large blocks with sides of approximately 60 cm to 1 m, or in the case of assembling in narrow parts such as corner blocks.

Furthermore, by connecting aggregates such as reinforcing bars to the recesses on the top and bottom of the blocks and connecting them via connectors, the blocks stacked one above the other can be connected with ease. Moreover, it can be made into a strong structure. Furthermore, since this part can be accessed from the outside even after construction, it is easy to disassemble and is suitable for construction.
