Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a concrete block used for a fence or a fence of a veranda, and particularly to a concrete block having an opening and having air permeability.

[0002]

[Prior art]

 Conventionally, concrete blocks are often used for walls and walls. In this case, the first problem is ventilation, and in order to overcome the heat during the summer, decorative blocks and blocks with vents are used.

For example, as shown in FIG. 5, ventilation blocks are ensured by arranging the ventilation hole block 21 in which holes such as circles, squares, or triangles are opened at appropriate times. It is a thing. Since these ventilation hole blocks 21 are formed by penetrating the ventilation holes 22a and 22b at right angles to the side surfaces, the ventilation holes 22a and 22b are transparent, and the inside can be seen from the outside. There was a privacy issue. Further, if the ventilation holes 22a and 22b are made large, the air permeability is improved, but there is a problem that sunlight is included more than necessary, and it returns and becomes hot.

[0004] Therefore, there is a device that has ventilation and is devised so that sunlight does not enter through the ventilation holes and the inside cannot be seen through. For example, FIG. 6 (1) is a device of a concrete block whose inside cannot be seen through (Actual No. 59-14319). In this invention, a vertical through hole 23 is opened in a concrete block, and a horizontal non-through hole 24 communicating at a right angle with the through hole is opened from both left and right sides so that the axes do not coincide with each other. As shown, the ventilation path is formed so as to be bent.

Further, FIG. 6 (3) is a device of a combination block in which the inside cannot be seen through (Japanese Utility Model Laid-Open No. 58-27414). This invention uses blocks 27a and 27b which are formed so as to have concave and convex portions 26a and 26b corresponding to each other, and the convex and concave portions 26a and 26b are set apart from each other for a certain period of time and combined so that the ventilation path is bent. It was designed to be used.

As described above, by refracting the ventilation path, it becomes impossible to see through the inside from the outside and sunlight cannot enter. Therefore, it has ventilation and light blocking properties, and can solve the problem of privacy.

[0007]

[Problems to be solved by the device]

 However, in the concrete block in which the ventilation holes 23 and 24 are communicated with each other as described above, the ventilation holes are small and the amount of ventilation is small. In addition, since the ventilation path is bent in ninety-nine folds, it cannot be said that the ventilation is excellent, it merely serves as a communication hole, and the natural wind from the outside is taken inward. It is impossible to enter. Therefore, the current situation is that we have not yet created a comfortable environment with the original fresh air flow. In addition, since the shape is complicated, it takes time and effort to manufacture, resulting in cost increase.

Further, in the case of the combination block, it is necessary to widen the interval between the corresponding concave and convex portions 26a and 26b in order to improve the ventilation, but if it is wide, the concave and convex portions 26a and 26b are increased. Completely opens, and the inside can be seen through the gap. Therefore, in reality, the interval between the concave and convex portions 26a and 26b must be narrow. Moreover, since the ventilation path is bent in a dogleg shape, it cannot be said that the ventilation is so good, and even in this case, the cool natural wind cannot be sufficiently taken into the inside. In addition, there is a problem in workability during construction, because it is necessary to adjust the spacing between the uneven portions with a spacer during construction.

The present invention has been made in view of the above-mentioned conventional problems, and has sufficient ventilation to take cool natural wind into the interior and reliable light shielding, and also has privacy. It was made to realize a highly reliable concrete block that can sufficiently protect the concrete.

[0010]

[Means for Solving the Problems]

 As shown in FIG. 1, the first aspect of the present invention is a concrete block 2 in which a concrete block 2 having an opening 1 is provided, and the opening 1 is formed in a slag shape. .

The opening 1 may be any opening as long as it has a sloping shape in which the inclined partition walls 3a and 3b are formed in an inclined shape so as to have an inclined ventilation path. For example, as illustrated in FIG. 1, a concrete block 2 in which a plurality of slanted partition walls 3a and 3b are provided on the outer frame 4 may be used. The inclination angle of the inclined partition walls 3a and 3b may be about 15 to 60 degrees with respect to the vertical as long as it has ventilation. Further, the number of inclined partition walls may be set arbitrarily, but it is best to provide a two-stage inclined partition wall having a size of two ordinary blocks at 45 degrees.

As shown in FIG. 1, a second aspect of the present invention is a concrete block in which the corners 5a and 5b at the ends of the slanted partition walls 3a and 3b of the blunt opening 1 are horizontally cut out. is there.

For example, as shown in FIG. 1 (2), the upper tip corner portion 5a and the lower tip corner portion 5b of each inclined partition wall 3a, 3b are horizontally cut out to form a lower portion of the upper inclined partition wall 3a. You may form so that the notch surface 5b and the upper notch surface 5a of the lower sloping partition wall 3b may become the same surface.

A third aspect of the present invention is a concrete block in which the inclined partition walls 3a and 3b of the rough opening 1 are curved. The inclined partition wall may have any shape as long as it has a curved shape. For example, as shown in FIG. 3 (1), the inclined partition wall is formed in a curved shape so as to have an S-shaped cross section for easy ventilation. It may be an inclined partition wall.

[0015]

[Action]

 In the concrete block 2 provided with the opening 1 as described in claim 1, when the opening 1 is formed in a rugged shape, the ventilation path 7 is wide, so that sufficient ventilation can be performed. Further, since the inclined partition walls 3a and 3b are provided substantially parallel to each other, the air blown in parallel to the inclined partition walls 3a and 3b has almost no obstacles, so that the rough opening 1 is smoothed. It can be blown into and blown inside. That is, since the ventilation path 7 is a straight line and is not bent, it does not impede the flow of the wind, and the outside wind is blown into the inside as it is, as indicated by the arrow in the figure.

Further, since the inclined partition walls 3a and 3b are arranged in a spiral shape, as shown by the dotted line in the figure, sunlight does not penetrate and the inside cannot be seen through, except in a fixed direction. . By setting the inclination angles and the directions of the inclined partition walls 3a and 3b, it is possible to arbitrarily adjust the light shielding and solve the privacy problem at the same time.

When the corners 5a and 5b at the ends of the slanted partition walls 3a and 3b of the rough opening 1 are horizontally cut out as in claim 2, the concrete block is cured to be manufactured. Easier to do. That is, as shown in FIG. 3 (2), curing can be performed with only a simple upper frame 8 and lower frame 9, no complicated formwork is required, and cutting work after curing is also required. do not do. The production of the mold and the work of assembling the mold are facilitated. Further, since the corner portions are eliminated, the mold can be easily removed after curing, and the concrete block can be constructed safely.

When the slanted partition walls 3a, 3b of the rough opening 1 are curved as in claim 3, the external wind smoothly flows through the curved ventilation passage 10, so that the inside smooths. Can be blown into. Further, when a strong wind blows, the curved surface ventilation path 10 becomes an appropriate obstacle, so that the strong wind is softened and a comfortable wind can be blown inside.

【Example】

 Next, practical examples of how the concrete block according to the present invention is embodied will be described.

FIG. 1 is an embodiment of a concrete block according to the present invention, (1) is an external perspective view, and (2) is a vertical sectional view taken along the line AA of (1). The concrete block 2 having this opening has a size corresponding to two ordinary hollow concrete blocks, and the outer frame 4 is approximately square with a 390 mm square. The thickness of the outer frame 4 and the two-level inclined partition walls 3a and 3b is 30 mm, and the depth is 100 mm. The inclination angle of the inclined partition walls 3a and 3b is 45 degrees. The upper end corner portion 5a and the lower end corner portion 5b of each inclined partition wall 3a, 3b are formed by horizontally cutting out, and the outer frame is formed so as to form a ventilation path 7 parallel to the inclined partition wall 3a, 3b. An inclined projection 4 a is formed on the surface 4.

The concrete block 2 having the openings formed in this manner has a large ventilation area because the openings are gully-shaped, and sufficient ventilation can be secured. Moreover, only the wind in the parallel direction can be blown into each of the inclined partition walls 3a and 3b, and only the sunlight in the parallel direction can be incident on each of the inclined partition walls 3a and 3b. The inside can be seen only from the direction parallel to the partition walls 3a and 3b.

FIG. 2 (1) is an example of use in which the concrete block according to the present invention is used for a balcony or a fence. In this usage example, the rubble-shaped concrete blocks 2 are installed horizontally, and the inclined partition walls 3a and 3b are provided obliquely downward on the front side, so that it is easy to take in the wind that blows up diagonally from the lower side. It does not include sunlight.

Further, the see-through property actually depends on the height of human eyes, but in a low place such as a fence, it is not possible to see through the interior in this state, but like the veranda or the rooftop fence, etc. On the contrary, when it is installed in a high place, the inclined partition walls 3a and 3b may be turned upward with the front side inclined. However, in this case, sunlight is likely to enter.

Further, as shown in FIG. 2 (2), the inclined partition walls 3a and 3b are installed in combination by changing the angle and the direction thereof to adjust the lighting, or as shown by an arrow in the figure, It is also possible to take in the wind blown from each direction one after another so that the wind is blown constantly. By utilizing these effects, it becomes possible to create a more comfortable living environment by installing terraces, entrances, porch and stair fences.

In many apartments and condominiums, the veranda is made of reinforced concrete or concrete blocks. In this case, iron handrails and the like are attached in consideration of air permeability, but they are often blindfolded because of their good transparency. If an opening is provided on the concrete surface instead of the handrail, both durability and safety can be remarkably improved, and if the opening is made into a sloping shape, ventilation can be remarkably improved and the inside and outside can be significantly improved. It will not be possible to see through easily, and the problem of privacy will be solved.

FIG. 3 is a vertical sectional view showing another embodiment of the concrete block according to the present invention, in which the inclined partition walls 6a and 6b are curved. As shown in the figure, two stages of sloping partition walls 6a and 6b are provided and have an S-shaped cross section. For this reason, there is no corner in the ventilation path 10, and the wind from the outside smoothly flows into the inside. In addition, when a strong wind such as a typhoon occurs, the curved ventilation path 10 becomes an appropriate obstacle, and the strong wind is weakened to become an appropriate wind force. Therefore, there is no fear that the strong wind blows in as it is.

FIG. 4 is an embodiment showing a method for manufacturing a concrete block according to the present invention. As shown in the figure, this concrete block is cured and manufactured by pouring mortar 11 from a mortar injection port 8a into a mold formed by an upper frame 8 and a lower frame 9 as shown in the figure. Since the corners of both tip portions 5a, 5b of the inclined partition walls 3a, 3b are removed, it is possible to manufacture with only the upper and lower molds 8 and 9, and the corners are damaged when the molds are removed. Since it does not happen, removal work becomes easy. Also, it is not necessary to finish the cutting after removing the formwork. Another feature of the present invention is that it is easy to manufacture.

[0028]

[Effect of device]

 According to the first aspect, since the opening 1 is formed in the shape of a spiral, the ventilation area is widened, and the air permeability can be greatly improved. Further, since the inclined partition walls 3a and 3b are installed substantially parallel to each other, the outside wind is easily blown into the inside, and the cool natural wind can be taken into the inside as it is. Furthermore, strong sunlight can be prevented, it is difficult to see the inside from the outside, and there is no privacy problem.

As described in claim 2, since the corner portions 5a, 5b at the end portions of the inclined partition walls 3a, 3b of the blunt opening 1 are horizontally cut out, the concrete block 2 can be easily formed. It can be manufactured by curing. In addition, it is safe to handle because there are few corners.

According to the third aspect, since the inclined partition walls 3a and 3b of the rough opening 1 are curved, it is possible to smoothly take in cool outside air into the inside. In addition, it can be an appropriate obstacle to strong winds such as typhoons, can moderately weaken the wind power, and prevent wind damage.

As described above, according to the present invention, a highly reliable concrete block which can sufficiently secure ventilation and can arbitrarily adjust sunlight and has no privacy problem. Can be realized.
