Description

Detailed Description of the Invention

The present invention is a concrete block product made of concrete, ceramics, stone, wood, glass, resin, plastic, etc., and a combination of these, and these block products are stacked and structured. The present invention relates to block products, thick-pattern products and structures for building objects.

Conventionally, in civil engineering and construction work, to prevent “displacement” at the joint of two materials, a small piece that digs a hole across both materials is called “thick pattern” (dabo). However, hardwood such as keyaki, nara, etc. has been used in round and square bars with galvanized stones and bricks.
In conventional masonry construction using bricks and stones, it is common practice to apply cement mortar etc. above and below the joint surfaces of the materials to be built and to build up and build up the structure. In the case of a simple masonry structure, a metal rigid material has been used as the aforementioned thick pattern.
If you check the block-related JIS standards,
Red brick: 10cm wide. 21cm long. Thickness 6cm. Long / short ratio 1: 2: 0.6.
Refractory brick: 11.4 cm wide. 23cm long. Thickness 6.5cm. Long / short ratio 1: 2: 0.6.
Ceramic brick: width 10cm. 21cm long. Thickness 6cm. Long / short ratio 1: 2: 0.6.
Cement brick: Same standard as red brick.
Insulated brick: Same standard as refractory brick.
Concrete block: 19cm wide. 39cm long. Thickness 10-15cm. Long / short ratio 2: 1.
Joint finish: width 20cm. 40 cm long. Thickness 10-15cm. Long / short ratio 2: 1.
As described above, it can be seen that the length ratio of the standards per member product for masonry construction in Japan is the length direction 2: the width direction 1.

Problems to be solved by the invention

However, these conventional methods have the following drawbacks.
I. It takes time to build up according to the dryness of the cement mortar at the joint. When putting thick patterns, stones and bricks are often damaged.
C. For ceramics, bricks, glass products, etc., due to expansion when heat is applied during production, it is difficult to obtain precise uniformity in products. Does not enter or is difficult to enter.
D. Skilled craftsmen are required for building.
E. Due to the wet bonding method, the surroundings of the part must be largely torn apart for repairing and repairing.
F. Due to the rigid structure, demolition takes a lot of labor and cost.
G. Because of its rigid structure, it is vulnerable to shaking and vibrations such as earthquakes.
H. Demolition waste must be disposed of as industrial waste from building waste.
Li. Existing materials cannot be used repeatedly.

The invention's effect

  The present invention has been made to solve the above-mentioned drawbacks, and provides a block product that can be re-made and used repeatedly, and a thick-pattern product that can be jointed without using a wet bonding method. There is to do.

Means for solving the problem

<Configuration 1>
The dimensions of the rectangular parallelepiped block product are, in principle, in accordance with the above-mentioned JIS standard, with the width ratio W: 1, the length direction L: 2, and the thickness direction: 0.6 as reference ratios. However, the block product formed into a dimension convenient for constructing the structure is set to an arbitrary dimension regardless of the reference ratio.
The block product has two “oval” thick holes centered at the intersection of the straight line drawn from the 1/4 and 3/4 points in the length direction perpendicular to the width direction and the center line in the width direction. It is provided.

FIG.

  The "oval" thick pattern hole is an individual difference of block products in joining and masonry of pottery, bricks, glass products, etc., where it is difficult to obtain precise uniformity due to expansion when heat is applied during production. The joint is made possible even if a slight shift occurs due to.

FIG.

FIG.

In addition, a so-called half-chocket (sometimes referred to as half-mass block) block product having a ratio of long: 1 and short: 1 has one thick pattern hole.
<Configuration 1-1>
The dimensions of the rectangular parallelepiped block product are, in principle, in accordance with the above-mentioned JIS standard, with the width ratio W: 1, the length direction L: 2, and the thickness direction: 0.6 as reference ratios. However, the block product formed into a dimension convenient for constructing the structure is set to an arbitrary dimension regardless of the reference ratio.
The block product has two "oval" thick holes centered at the intersection of the straight line drawn from the 1/4 and 3/4 points in the length direction perpendicular to the width direction and the center line in the width direction. About the shape of the thick hole, the height direction is divided into two equal parts, and the thick hole in the upper part 1/2 is “elliptical” and the thick hole in the lower part 1/2 is “true circle” It is characterized by being.
This feature further enhances the robustness of the joint when joining and assembling the block structure over the block product described in <Configuration 1>.

FIG.

  The so-called half-chocket (sometimes referred to as half-mass) block product with a ratio of long: 1 and short: 1 has one thick pattern hole.

<Configuration 2>
A thick pattern product used for joining block products is formed of a hard elastic body, a rubber product, a metal, or a composite thereof, and has a cylindrical shape.

FIG.

  This thick pattern product has a length less than the dimension of the thick pattern hole (upper surface hole + lower surface hole) of the block product described in the previous section, and a flange is provided at an intermediate position. When joining and assembling block products, the upper part from the flange is inserted into the lower thick hole of the block product, and the lower part from the flange is inserted into the upper thick hole of the already built block product. Joint products together.

FIG.

  Thereafter, this operation is sequentially repeated to obtain a desired block structure.

<Configuration 3>
<Configuration 1> In order to make the joint between the block products described in <Configuration 2> elastic and to have an earthquake-resistant block structure, a cylindrical rubber having irregularities on the surface of the thick hole of the block product is used. Install.

FIG.

FIG.

  As a result, the joint between the thick pattern hole and the thick pattern increases and a strong joint force can be obtained. At the same time, the joint part absorbs vibrations in the vertical and horizontal directions, further increasing the rigidity of the block structure.

FIG.

The cylindrical rubber mentioned above is somewhat affected by individual differences in block products in the bonding and masonry of ceramics, bricks, glass products, etc., which are difficult to obtain precise uniformity due to expansion when heated during production. Block structure that plays the role of packing in the horizontal direction against the occurrence of misalignment, strengthens the adhesion and cushioning properties of the block product and thick pattern, and is resistant to vibration (seismic isolation structure) Can be built.
The following describes the advantages over conventional products.

Advantages of masonry

I. Joining and assembling of block products is a simple operation that simply inserts a thick pattern into a thick pattern hole and then inserts a column (core bar), so no skilled worker is required to pile up.
B. Because it is a dry construction method that does not require cemented, mortar, and other adhesives to join block products, it is a construction period compared to a wet construction method that accumulates according to the dryness of cement, mortar, other adhesives, etc. Can be greatly shortened.
C. Construction in cold areas where it takes time to dry cement, mortar, and other adhesives can also be performed regardless of the climate.
D. Even if there is some deviation between blocks due to individual differences in the block product during the assembly of the block structure, the shape of the elliptical thick hole, the cylinder with the irregularities attached to the surface of the thick hole of the block product The block-like structure can be constructed without damaging the adhesion between the block products by the rubber-like rubber.
E. The dry construction method eliminates the need for work during construction such as kneading cement and mortar, reduces the work load of masonry, and also eliminates the need for cleanup because the construction site is not soiled.

Advantages of dismantling structures

I. Unlike the conventional wet bonding method, the structure can be easily disassembled simply by removing the thick pattern.
B. There is very little noise generated when dismantling.
C. There is very little dust when dismantling.

Advantages after dismantling the structure

I. The dismantled block product can be used again.
B. The dismantled and removed thick pattern can be used again.
