Description

  The present invention provides both obstacles that block fluoroscopy and sunlight (including “shielding and shading”) and breathability (or ventilation) that does not block wind and airflow. It relates to compatible blocks.

  In order to construct a building exterior (wall), a wall surface, etc. easily, a block formed in advance in a predetermined shape (usually a substantially rectangular shape) is often used. Since the block usually consists of opposing solid wall surfaces, the block is excellent in hindrance but lacks air permeability. On the other hand, a block having a hollow opposing wall surface is excellent in air permeability but lacks obstruction properties because the opposite side can be seen through.

  Then, the block which can satisfy | fill both obstruction property and air permeability is proposed, for example, there exists description relevant to the following literature.

  All of the conventional blocks 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 the above circumstances, and provides a block that can reliably satisfy both obstacles and air permeability, has a relatively simple shape, is easy to manufacture, and has excellent aesthetics. With the goal.

  As a result of diligent research to solve this problem, the present inventor found that the through holes are alternately arranged in the opposite wall surface (front wall) and back wall (rear wall). came up with. By developing this, the present invention described below has been completed.

"block"
(1) The block of the present invention includes a substantially rectangular front wall portion, a substantially rectangular rear wall portion opposed to the front wall portion, and a bottom portion connecting the front wall portion and the rear wall portion on the lower side. And a block comprising:
The front wall portion has a front hole penetrating on one side in the left-right direction, the rear wall portion has a rear hole penetrating on the other side in the left-right direction, and the front hole and the rear hole are in the front-rear direction. It has a shape and arrangement that do not overlap.

(2) In the block of the present invention, a front hole and a rear hole that are alternately arranged in the left-right direction are provided in the front wall portion and the rear wall portion that are arranged to face each other. Since these front holes and rear holes are shaped and arranged so as not to overlap in the front-rear direction, as long as they are viewed at least in front of the front wall part or the rear wall part, the front hole and the rear hole should be seen through from one to the other. I can't. Thus, the block of the present invention has sufficient obstacles in normal use.

  Next, as for the block of this invention, the front wall part and the rear wall part are connected by the bottom part. For this reason, naturally, a gap is formed between the front wall portion and the rear wall portion, and an internal space (referred to as an “inner space”) formed between the front wall portion and the rear wall portion is formed above the bottom portion. Is done. Through this internal space, the rear hole of the rear wall is communicated with the rear hole of the front wall. Thus, an air flow path serving as a passage for wind or the like is formed by the front hole, the inner space and the rear hole, and the block of the present invention has sufficient air permeability.

  Therefore, if the block of the present invention is used, both obstruction and breathability can be achieved 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 portion and the rear wall portion that are arranged forward and backward via the bottom portion, and thus, similar to the conventional block. It can be easily manufactured using a mold or the like. Furthermore, since the blocks of the present invention are not complicated and strange shapes, the aesthetics as a single unit is good, and the overall appearance of a wall or a wall constructed by stacking a large number of blocks can be improved.

<Others>
(1) In this specification, the front wall portion and the rear wall portion are appropriately combined or one of them is simply referred to as “wall portion”. In addition, the front hole and the rear hole are combined, or one of the holes 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 referred to as the vertical direction. Of these, the direction where the bottom is located is called the lower side, and the opposite side is called the upper side. And the direction orthogonal to the up-down direction is called the left-right direction. Anyway, front and rear, left and right, and top and bottom in the present specification are only a convenient expression for explaining the block of the present invention, and unless otherwise specified, the form and usage of the block are limited. is not.

It is a whole perspective view of the block which is one Example. It is the sectional drawing (AA sectional drawing).

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

<Outline>
Since the blocks are usually used by being stacked, it is preferable that the blocks have a substantially rectangular shape such as a rectangular parallelepiped in consideration of the effectiveness. Of course, 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 portion and the rear wall portion are skeletons. Although it is sufficient that these both wall portions are connected at the bottom portion, it is usually preferable that they are also connected on the left and right sides of both wall portions in order to ensure the strength and rigidity of the block. Therefore, the block of the present invention preferably has a left side portion and a right side portion that connect the front wall portion and the rear wall portion on the left and right sides (particularly in the vicinity of the end portion).

  It is preferable that the left side portion and the right side portion are at least outside each hole so as not to impair air permeability due to the front hole, the rear hole, and the internal space. For example, when the front hole is arranged on the right side of the front wall part and the rear hole is arranged on the left side of the rear wall part, the right side part connecting the front wall part and the rear wall part is further of the front hole. On the right side, the left side is preferably located further to the left of the rear hole.

  It is preferable that the left side or the right side has a vertical groove that extends in the vertical direction and is opened outward so that reinforcing bars such as reinforcing bars can be arranged. Needless to say, a reinforcing bar penetrating in the vertical direction may be provided inside the block (for example, near the center).

  The upper side of the block (opposite the bottom) may be open, or at least part of it may be closed. However, it is preferable that the entire upper side is in an open state because it is easy to manufacture a block (particularly, the inner space or the bottom).

《Front and back holes》
The front hole and the rear hole communicate with each other through the inner space, and various shapes and arrangements are conceivable as long as the obstruction and breathability are ensured. For example, the hole shape may be a round shape, a fan shape, a triangular shape, a square shape, a polygonal shape, or other different shapes. However, it is preferable that the front hole and the rear hole are round holes because they are easy to manufacture, excellent in aesthetics, etc., and can be prevented from 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 It is preferable that the portion on the lower left side or the lower right side is connected to the front hole or the rear hole on the lower side. Thereby, rainwater or the like that has entered the inner space from the front hole or rear hole on the upper side is easily drained to the outside from the front hole or rear hole on the lower side.

  The inclined surface is sufficient to guide moisture or the like that has entered the internal space to the front hole or the rear hole. Accordingly, various positional relations and connection forms between the end of the inclined surface and the front hole or the rear hole are conceivable. But it is so preferable that it is the form which does not impair the design property of a front hole or a back hole by a bottom part (especially 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.

  Furthermore, it is preferable that the bottom portion has a groove communicating with one of the front hole and the rear hole on the lower side of the inclined surface. This groove acts like a ridge, 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 is excellent in design.

<Application>
The block of the present invention can be used for various applications. A typical example is a case where it is used for a wall or a 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 according to the application. In the case of building blocks, concrete blocks are common. The block may be a color as it is, or may be colored reddish brown or brown.

  A block B which is an embodiment of the present invention is shown in FIGS. 2 is a cross-sectional view taken along the line AA shown in FIG. 1 (cross-sectional view with respect to the front-rear direction). The present invention will be described in more detail based on this embodiment. In this embodiment, the front-rear direction, the left-right direction, and the up-down direction are determined for convenience as shown in FIG.

"Overview"
The block B has a substantially bottomed cylindrical shape, 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 cage that forms at least a part of the exterior.

  The front wall portion 1 and the rear wall portion 2 are substantially rectangular plate shapes. 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 back side has a rear hole 21 made of a round through hole at the upper left.

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

  The bottom portion 3 further has a substantially semi-cylindrical drainage groove 32 formed along a lower outer shape (a cross section is an arc shape or a semicircular shape) of the front hole 32 on the right end side. The inclined surface 31 is smoothly connected to the drainage groove 32 on the right end side. Thus, the bottom part 3 has a shape in which the inclined surface 31 and the drainage groove 32 do not intersect with the front hole 11 which is a through-round 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 portion 5 connects the front wall portion 11 and the rear wall portion 22 inside the right end of the block B. The left outer side of the left side portion 4 has a semi-cylindrical groove 41 (vertical groove for reinforcing bars) extending in the vertical direction, and the right outer side of the right side portion 5 is a semi-cylindrical groove extending in the vertical direction. 51 (longitudinal groove for reinforcing bars).

<Action>
When a large number of blocks B are stacked in the vertical direction and the horizontal direction, a substantially cylindrical shape is formed by the grooves 41 and the grooves 51. After placing the rebar and pouring the ready-mixed concrete there, when the concrete solidifies, a strong block fence (not shown) is constructed.

  Each block B constituting the block wall is formed with a front hole 11 and a rear hole 21 penetrating the front wall portion 1 and the rear wall portion 2 respectively, and the front hole 11 and the rear hole 21 have a narrow space s. It is in a state of communication through. For this reason, the wind etc. which entered from one of the front hole 11 and the rear hole 21 easily escape to the other. Thus, even if a block rod using the block B is provided, sufficient air permeability is ensured.

  In addition, as shown in FIG. 1, the front hole 11 and the rear hole 21 have shapes and arrangements that do not overlap in the front-rear direction. For this reason, as long as it faces at least the block wall, it is not possible to see through the appearance of a residence or the like inside the block wall. That is, the block wall using the block B also ensures almost complete obstacles.

  Further, even if rain or the like enters the inside from the rear hole 21 on the upper side of each block B, the rainwater or the like that has entered flows along the inclined surface 31 of the bottom 3 and is guided to the drainage groove 32. And it drains outside from the drainage groove 32 through the front hole 11 on the lower side. Therefore, the block wall using the block B hardly collects water or the like inside, and is excellent in drainage.

  In addition, although the present Example demonstrated the case where the whole block cage | basket was constructed | assembled with the block B, the block B is suitably arrange | positioned combining with the solid general block which does not have the front hole 11 and the rear hole 21. May be. In any case, it is possible to construct a beautiful block wall that is secured with hindrance, air permeability, drainage and the like.

  Incidentally, since the upper part of the block B is open, it is easy to form the bottom part 3 having the inclined surface 31 and the drainage groove 32. Moreover, the front hole 11 and the rear hole 21 are also through-round holes and can be easily formed. Therefore, the block B is easy to manufacture as a whole.
