Description

  The present invention relates to a barrier property (which is simply referred to as a "blocking property" including a shielding property and a light shielding property) which blocks see-through and sunlight, and a ventilation property (or a ventilation property) which does not block a wind or an air current. For compatible blocks.

  In order to easily construct the external structure (fence), wall surface, and the like of a building, a block formed in a predetermined shape (usually a substantially square shape) is often used. Since the blocks are usually formed of solid walls facing each other, the blocks are excellent in the shielding property but lack in the air permeability. On the other hand, a block whose opposing wall surface is hollow is excellent in air permeability, but lacks barrier properties because the opposite side can be seen through.

  In view of the above, a block capable of achieving both a screen and air permeability has been proposed. For example, there is a description related to the following literature.

JP 2008-150783 A Utility Model Registration No. 3018805 Japanese Utility Model Registration No. 3027076

  All of the conventional blocks described in such patent documents have complicated shapes, are difficult to manufacture, and are not preferable in terms of design.

  The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a block that is capable of reliably balancing a screen and air permeability, has a relatively simple shape, is easy to manufacture, and has an excellent appearance. With the goal.

  As a result of intensive studies to solve this problem, the present inventor has found that through holes are alternately arranged on the opposing front wall (front wall) and rear wall (rear wall). came up with. By developing this, the present invention described below has been completed.

"block"
(1) A block according to the present invention comprises a substantially rectangular front wall, a substantially rectangular rear wall facing the front wall, and a bottom connecting the front wall and the rear wall at a lower side. And a block having
The front wall has a hole before penetrating the one side in the lateral direction, the rear wall portion has a hole after penetrating the other side in the lateral direction, the front hole and the rear hole in the longitudinal direction The front hole is arranged on one side in the vertical direction, the rear hole is arranged on the other side in the vertical direction, and the upper surface of the bottom is characterized Rukoto that have a one inclined surface inclined from the upper side to the other lower side of the.

(2) In the block according to the present invention, the front wall and the rear wall disposed opposite to each other are provided with a front hole and a rear hole which are alternately arranged in the left-right direction. Since these front and rear holes are shaped and arranged so that they do not overlap in the front-rear direction, at least one of the front and rear holes must be seen through the other as far as the front wall or rear wall is viewed directly. Can not. Thus, the block of the present invention first has sufficient barrier properties in normal use.

  Next, in the block of the present invention, the front wall and the rear wall are connected at the bottom. Therefore, a gap is naturally formed between the front wall portion and the rear wall portion, and an internal space (referred to as an “interposed space”) formed between the front wall portion and the rear wall portion is formed above the bottom portion. Is done. The front hole of the front wall portion and the rear hole of the rear wall portion communicate with each other via the inner sandwiched space. In this way, the front hole, the inner space, and the rear hole form an air flow path that serves as a passage for wind and the like, and the block of the present invention also has sufficient air permeability.

  Therefore, the use of the block of the present invention makes it possible to achieve both high screen and air permeability at a high level. In addition, the block of the present invention has a simple shape in which the front hole and the rear hole are alternately arranged on the front wall and the rear wall, which are arranged back and forth via the bottom, respectively. It can be easily manufactured using a mold or the like. Further, since the blocks of the present invention do not have a complicated and strange shape, etc., the aesthetic appearance as a single unit is good, and the overall appearance of a fence or wall constructed by stacking a large number of blocks can be improved.

《Other》
(1) In this specification, the front wall portion and the rear wall portion are referred to as appropriate, together or simply referred to as “wall portions”. In addition, the front hole and the rear hole together or one of them is simply referred to as a “hole”.

(2) In this specification, for convenience, the direction in which the front wall portion and the rear wall portion are disposed is the front-rear direction, and the direction orthogonal to the front-rear direction (the direction in which each wall portion extends) is the left-right direction. Or called up and down. Of these, the direction in which the bottom is located is referred to as downward, and the opposite side is referred to as upward. And the direction orthogonal to the up-down direction is called the left-right direction. In any case, the terms front and rear, left and right, and top and bottom referred to in the present specification are merely expressions for convenience of describing the blocks of the present invention, and unless otherwise specified, limit the form and usage of the blocks. is not.

1 is an overall perspective view of a block according to one embodiment. It is sectional drawing (AA sectional drawing).

  One or more components arbitrarily selected from the present specification can be added to the components of the present invention described above. Which embodiment is best depends on the target, required performance, and the like.

《Overview》
Since the blocks are usually used in a stacked state, it is preferable that the blocks have a substantially rectangular shape such as a rectangular parallelepiped in consideration of workability. Needless to say, the corners and the like may be appropriately chamfered by a flat surface or a curved surface.

  In the block according to the present invention, the front wall and the rear wall form a skeleton. It suffices that these two walls are connected at the bottom, but it is usually preferable that they are also connected on the left and right sides of both walls in order to ensure the strength and rigidity of the block. Therefore, the block of the present invention preferably has a left portion and a right portion that connect the front wall portion and the rear wall portion on the left and right sides (particularly near the ends).

  The left and right portions are preferably at least outside each hole so as not to impair air permeability due to the front hole, the rear hole and the inner space. For example, when the front hole is located closer to the right side of the front wall and the rear hole is located closer to the left side of the rear wall, the right side connecting the front wall and the rear wall is further away from the front hole. Preferably, it is arranged on the right side and the left side on the left side of the rear hole.

  It is preferable that the left side portion or the right side portion has a vertical groove that extends in the up-down direction and is opened outward so that reinforcement such as a reinforcing bar can be arranged. Of course, a reinforcing arrangement hole penetrating in the vertical direction may be provided inside the block (for example, near the center).

  The upper side of the block (the side opposite to the bottom) may be open, or at least a part thereof may be closed. However, it is preferable that the block (particularly, the sandwiched space and the bottom portion) be easily formed when the entire upper side is open.

《Front hole and rear hole》
The front hole and the rear hole communicate with each other via the inner sandwiched space, and various shapes and arrangements are conceivable as long as the shielding property and the air permeability are secured. For example, the hole shape may be a round shape, a fan shape, a triangular shape, a square shape, a polygonal shape, or another different shape. However, it is preferable that each of the front hole and the rear hole is a round hole because it is easy to manufacture, has excellent aesthetics, and can suppress cracking due to stress concentration.

"bottom"
The bottom portion connecting the front wall portion and the rear wall portion on the lower inner side has an inclined surface inclined from one upper side in the left-right direction to the other lower side, and a part of the inclined surface (particularly, The lower left or lower right portion) is preferably connected to the lower front hole or the rear hole. As a result, rainwater or the like that has entered the inner space from the front hole or the rear hole on the upper side is easily drained to the outside from the front hole or the rear hole on the lower side.

  The inclined surface is sufficient to guide moisture or the like that has entered the inner space to the front hole or the rear hole. Therefore, the positional relationship between the end of the inclined surface and the front hole or the rear hole, the connection form, and the like can be variously considered. However, it is more preferable that the design of the front hole or the rear hole is not impaired by the bottom (particularly, the inclined surface). Therefore, it is preferable that the end of the inclined surface is smoothly connected to the outer shape of the front hole or the rear hole.

  Further, it is preferable that the bottom has a groove below the inclined surface and communicates with one of the front hole and the rear hole. This groove acts like a gutter, and the drainage of the block can be further improved. Further, when the cross-sectional shape of the groove is along the outer shape of the front hole or the rear hole on the lower side, the block of the present invention also has excellent design.

《Applications》
The block of the present invention can be used for various applications. A typical example is a case where it is used for a fence or wall of a building. Various materials can be considered for the block, and an appropriate material is selected from fired products such as concrete and clay, resin, and the like, depending on the application. In the case of building blocks, concrete blocks are common. Further, the block may be the color of the material as it is, or may be a block colored reddish brown or brown.

  A block B according to an embodiment of the present invention is shown in FIGS. FIG. 2 is a cross-sectional view (a cross-sectional view in the front-rear direction) taken along the line AA shown in FIG. The present invention will be described in more detail based on this embodiment. In this embodiment, the front-back direction, the left-right direction, or the up-down direction is determined for convenience as shown in FIG.

"Overview"
The block B has a substantially cylindrical shape with a bottom, and includes a front wall portion 1, a rear wall portion 2, a bottom portion 3, a left side portion 4, and a right side portion 5. The block B is made of concrete, and is used for construction of a fence forming at least a part of an external structure.

  The front wall portion 1 and the rear wall portion 2 have a substantially rectangular plate shape. The front wall portion 1 on the front side has a front hole 11 formed of a round through hole at the lower right. The rear wall portion 2 on the rear side has a rear hole 21 formed of a round through hole at the upper left.

  The bottom part 3 connects the front wall part 11 and the rear wall part 22 at the lower inner side. The upper surface of the bottom 3 is an inclined surface 31 inclined from upper left to lower right. The left end of the inclined surface 31 is slightly below the lower end of the rear hole 21. The right end of the inclined surface 31 is connected to the lower left portion of the front hole 11.

  The bottom 3 further has a substantially semi-cylindrical drain groove 32 formed along the outer shape (a cross section of an arc or a semicircle) below the front hole 32 on the right end side. The inclined surface 31 is smoothly connected to the drain groove 32 on the right end side. As described above, the bottom 3 has a shape in which the inclined surface 31 and the drain groove 32 do not intersect with the front hole 11 which is a through-hole, and the block B is also excellent in design.

  The left side portion 4 connects the front wall portion 11 and the rear wall portion 22 inside the left end of the block B. The right side part 5 connects the front wall part 11 and the rear wall part 22 inside the right end of the block B. The left outer side of the left part 4 has a semi-cylindrical groove 41 (vertical groove for reinforcing arrangement) extending in the vertical direction, and the right outer part of the right part 5 has a semi-cylindrical groove extending in the vertical direction. 51 (reinforcement vertical groove).

《Action》
When a large number of blocks B are stacked and arranged in the vertical and horizontal directions, each groove 41 and each groove 51 form a substantially cylinder. After the rebar is placed and the ready-mixed concrete is poured, the concrete solidifies and a solid block wall (not shown) is constructed.

  In each block B constituting the block wall, a front hole 11 and a rear hole 21 penetrating the front wall portion 1 and the rear wall portion 2, respectively, are formed. It is in a state of being communicated through. Therefore, wind or the like entering from one of the front hole 11 and the rear hole 21 easily escapes to the other. Thus, even if the block wall using the block B is provided, sufficient ventilation is ensured.

  Further, as shown in FIG. 1, the front hole 11 and the rear hole 21 are shaped and arranged so as not to overlap in the front-rear direction. For this reason, it is not possible to see through the state of the house and the like inside the block wall as long as it is facing at least the block wall. In other words, the block wall using the block B also secures almost perfect barrier property.

  Further, even if rain or the like enters the inside from the rear hole 21 above each block B, the infiltrated rainwater or the like flows along the inclined surface 31 of the bottom 3 and is guided to the drain groove 32. Then, the water is drained from the drain groove 32 to the outside through the front hole 11 on the lower side. Therefore, the block wall using the block B hardly accumulates water and the like inside and is excellent in drainage.

  In this embodiment, the case where the entire block wall is constructed with the block B has been described. However, the block B is appropriately arranged in combination with a general solid block having no front hole 11 and rear hole 21. May be. In any case, it is possible to construct a beautiful block wall with good blocking, ventilation, drainage, and the like.

  By the way, since the block B is open at the top, the bottom 3 having the inclined surface 31 and the drain groove 32 can be easily formed. Further, the front hole 11 and the rear hole 21 are also round through holes, and can be easily formed. Therefore, the block B is also easy to manufacture as a whole.
