Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation block for ventilating a room through a glass block wall mainly constructed of a glass block.

[0002]

2. Description of the Related Art A general glass block used for constructing a transparent or translucent wall is shown in FIG. The glass block 31 shown in the figure is formed as a hollow hermetically sealed glass box by a pair of bottomed glass bodies formed by a mold, butted at respective openings, and then heated and welded with a burner or the like. Provided. At this time, the front and rear flat plate portions 3
A welded portion 36 having a built-up shape is formed over the entire circumference of the recess 35 between the portions 4 and 34. Thereafter, the whole is contracted by slow cooling, and the inside of the square hole 37, that is, the internal space 38 is set to about 0.3 atm. The outer dimensions of the unit of the glass block 31 such as height H, width S, and depth W are standardized to, for example, about six types. In the case of a frontal square, the height H and the width S are of the same size.

The above-mentioned glass blocks 31 are stacked, for example, in a grid pattern, and the concave portions 3 of the glass blocks 31 are formed.
A vertical reinforcing bar and a horizontal reinforcing bar are arranged between 5, 35, and are further filled with mortar to form a wall. According to the wall made of the glass block 31 as described above, the room can be lit when the weather is fine, so that the room becomes bright, and the outside of the room can be seen from the room. In addition, the prism effect creates a beautiful atmosphere in the room, which has been well received.

[0004]

However, since the conventional glass block wall is constructed without gaps by a large number of glass blocks and joint mortar, some people may feel a sense of airtightness and suffocate. Also, ventilation was not possible even if tobacco smoke, odor, flammable gas, or dangerous substance gas was floating near the wall. On the other hand, if sunlight passes through the glass block and enters the room, even if the room is kept at an appropriate temperature by the air conditioning equipment, the sun-irradiated part may be heated by radiant heat and may cause discomfort. .

[0005] Therefore, it is conceivable to secure a space for installing a ventilation fan in advance when constructing a wall, stack a glass block around the space, and then install a ventilation fan in the installation space. However, since the size of the ventilation fan is relatively large, an installation space corresponding to a large number of glass blocks must be secured. For example, if a ventilation fan is installed in the installation space for 4 to 9 glass blocks, the wall holding strength around it will decrease, and the mortar will crack or fall off over time, and the glass block itself will break or fall off. Or
In addition, since the size of the ventilation fan often does not match the standard size of the glass block, a means for adjusting the size is separately required.

On the other hand, in the case where a space for installing a ventilation fan is newly provided for the glass block wall already constructed, the wall holding strength of the remaining portion must be taken into consideration. However, a reinforcing sash for fixing the ventilation fan is also required, and an increase in cost cannot be avoided. Moreover, in recent years, the construction area of the glass block wall has become considerably large, so if a part of the glass block wall once built is hollowed out as an installation space, the holding strength of the glass block around the installation space is remarkable. May drop.

[0007] The present invention has been made in view of the above-mentioned conventional problems, and can provide a ventilation function while maintaining strength at a certain level or more to a wall mainly constructed of a glass block. The purpose is to provide a ventilation block.

[0008]

In order to achieve the above object, a ventilation block according to the present invention comprises a block body formed to have substantially the same dimensions as the outer contour of a glass block which is stacked to form a wall. The block main body is provided with a ventilation hole penetrating in a direction perpendicular to the surface of the wall to be constructed.

[0009] In the above structure, the ventilation hole of the block main body is provided with a water-stop ventilation portion that allows air to pass through but does not allow water to pass.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a ventilation block according to an embodiment of the present invention, FIG. 2 is a front view showing a block main body used in the ventilation block, and FIG. 3 is a front view showing a water blocking ventilation section used in the ventilation block. FIG. 4 and FIG. 4 are rear views showing a ventilation amount adjusting section used in the ventilation block, and FIG. 5 is a sectional view taken along line AA in FIG.

First, in FIGS. 1 and 5, a ventilation block 1 has a block main body 2 formed in a rectangular tube shape as a whole, and a water blocking ventilation section 8 mounted on the front surface of the block main body 2.
And a ventilation amount adjusting unit 1 mounted on the back of the block body 2

Is formed to have substantially the same dimensions as the outer contour of the glass block 31 (see FIG. 11) as a whole. That is, the height H, the width S, and the depth W are the same as those of the glass block 31.

As shown in FIG. 2, the block main body 2 is composed of a frame 4 made of an aluminum plate or the like into a rectangular tube shape. The frame 4 has a square hole-shaped ventilation hole 3 inside, and has a concave portion 5 which is inwardly recessed over the entire outer surface. The ventilation hole 3 is formed so as to communicate the front side and the rear side of the frame 4. In addition, embedding nuts 6 are embedded in the corners of the front surface and the rear surface (not shown) of the frame body 4 respectively. These embedding nuts 6 are for fixing the water stop ventilation section 8 and the ventilation amount adjusting section 14 with screws 7 and screws 24 (see FIG. 5).

As shown in FIG. 3, the water-stop ventilation section 8 includes a plate body 9 having a square hole-like ventilation hole 10 formed in a square frame shape as viewed from the front with an aluminum plate or the like, for example. And a plurality of rattle blades 13, 13, 13, 13... That are horizontally mounted on the plate body 9 in a posture inclined outward and downward to cover the ventilation holes 10. And screw holes 12 formed in the corners of the plate 9 respectively.

When a glass block wall is constructed as an outer wall exposed to rain, it is absolutely necessary to prevent rainwater R or the like from entering the room from the ventilation block 1. Therefore, the water blocking ventilation section 8 is provided in the block body 2.
Are provided on the front surface of the ventilation hole 3 so as to allow air to pass therethrough but not water through a large number of rattle blades 13, 13,....

As shown in FIG. 4, the ventilation amount adjusting section 14 has a plate 15 formed of, for example, an aluminum plate and formed in a square shape in a front view, and is slidably disposed along the inner surface of the plate 15. And the slide plate 19 thus formed.
The plate body 15 is provided with a vertically long ventilation hole 16, a horizontally long guide hole 17 at a central portion, and a screw hole 18 at a corner. Further, a guide support plate 26 (see FIG. 5) for guiding and supporting the slide plate 19 so as to be slidable in the lateral direction is provided on the upper and lower inner surfaces of the plate body 15. The slide plate 19 is provided with a large number of ventilation holes 20 having the same size and arrangement as the ventilation holes 16. A wire mesh 21 for insect and dust proof is provided over almost the entire inside of the slide plate 19. Further, the knob 22 is attached to the slide plate 19 in a state of being slidably inserted into the guide hole 17 of the plate 15. This ventilation amount adjusting unit 14 is
5 (see FIG. 5), and is fixed to the back surface of the block main body 2.

Next, a description will be given of a case where the ventilation block 1 is used together with a large number of glass blocks 31 in constructing a wall. In FIG. 6, a number of glass blocks 31, 31, and
Are piled up in a grid pattern, and the wall body 40 is constructed. Also, the ventilation blocks 1, 1,... Are arranged at desired positions mixed with the glass block 31. At this time, the ventilation block 1 is arranged such that the ventilation holes 3 penetrate at right angles to the surface of the wall body 40. Then, each of 4
A vertical reinforcing bar 41 or a horizontal reinforcing bar 42 is arranged between the concave portions 5, 5, 35 of each block, and a mortar 43
Is embedded and reinforced. However, the vertical reinforcing bars 41 or the horizontal reinforcing bars 42 are not limited to four blocks in each of the vertical and horizontal directions, but may be disposed in an appropriate number of blocks, for example, may be disposed in each of the vertical and horizontal blocks.

According to the wall 40 thus constructed,
Through the ventilation holes 10 between the rattle blades 13, 13 of the ventilation blocks 1, 1,... Arranged in several places, the ventilation holes 3 in the block main body 2, and the ventilation holes 16, 20 of the ventilation amount adjusting section 14 (see FIG. 5). ), Ventilation can be performed by exhausting indoor air or taking in outdoor air. Accordingly, even if the room is full of tobacco smoke, the room moves close to the wall 40, so that fresh air flowing in through the ventilation blocks 1, 1,. it can. On the other hand, in the case of rainy weather, etc., the rainwater R is rebounded by the rattle blades 13 and does not flow into the room due to the presence of the water stop ventilation section 8 on the front surface. As the water blocking ventilation section 8, the vertical and horizontal dimensions of a general-purpose gallery can be diverted according to the glass block standard.

On the other hand, the ventilation block 1 is provided with a ventilation amount adjusting unit 14.
By operating the knob 22 to slide the slide plate 19 sideways, the amount of airflow can be adjusted by adjusting the overlapping area of the air holes 16, 20. Also,
When the wind and rain is extremely strong, the vent hole 16 can be completely closed to shut off the rainwater accompanying the strong wind, so that the ventilation amount adjusting section 14 at this time also functions as a water stop ventilation section. The ventilation amount adjusting unit 14 may be diverted according to the glass block standard with respect to the vertical and horizontal dimensions of the general-purpose register. That is, this ventilation block 1 is used for various buildings, kindergartens, various schools, amusement facilities,
It can be suitably used for a glass block wall to be built in a government office, a hospital, a nursing home, and other buildings.

The water-stop ventilation section is not limited to the above-mentioned gull-grip type, and the water-stop ventilation section 8a shown in FIG. 7 can also be used. In the water stop ventilation section 8a, a plurality of plate members 9a, 9
b and 9c are used in the depth direction. These plate bodies 9a, 9b, 9c are provided with small-diameter ventilation holes 10a, 10b, 10c.
c is formed in the shape of a perforated metal with a large number of perforations. The ventilation holes 10a, 10b, and 10c are provided in such a manner that their drilling positions are staggered in the vertical or horizontal direction. That is, since the water blocking ventilation part 8a has a simple configuration, it is provided at low cost.

Further, a water stop ventilation section 8b shown in FIG. 8 can be employed. The water-stop ventilation portion 8b is provided with a plurality of bell-shaped bulging portions 27 that are pushed forward from the plate body 9d by press working. Then, at the time of press working, the lower side of the bulging portion 27 is cut off to form the ventilation hole 10d.
That is, since the water blocking ventilation portion 8b can be easily obtained by pressing a single plate, it is inexpensive and has high rigidity.

Furthermore, in the above-described embodiment, the glass block 31 and the ventilation block 1 are stacked neatly in a grid pattern to construct the wall body 40. However, the present invention is not limited to this. May be shifted by half a pitch to the left and right. Alternatively, they may be arranged vertically vertically half-pitch shifted horizontally next to one stacked vertically. Further, the pitch to be shifted is not limited to a half pitch, and can be appropriately set within a range in which a wall can be constructed. And
The vertical and horizontal dimensions of the ventilation block may be the total dimensions of two or more glass blocks including the joint mortar.

In the above-described embodiment, the water blocking portions 8, 8a, 8b and the flow rate adjusting portion 14 are omitted to form a ventilation block having a ventilation hole having a relatively large diameter. If it is arranged under the, it can also be used as a path for pet cats and small dogs.

FIGS. 9 and 10 show a ventilation block according to another embodiment of the present invention. The ventilation block 1a shown in each figure differs from the ventilation block 1 of the above-described embodiment in that the frame 4a of the block body 2a is made of a casting obtained by, for example, a lost wax method.
Both the water stop ventilation section 8 and the ventilation amount adjustment section 14 are fixed by screws 7 screwed from the indoor side, and the bottom surface 29 of the ventilation hole 3 in the block main body 2a faces downward toward the outside. That is, it is formed to be inclined. still,
The insect- and dust-proof wire mesh 21 and the water-stop ventilation section 8 are integrally screwed to the rear side of the inward section formed at the front portion in the frame 4a.

Therefore, according to this embodiment, since the frame 4a of the block main body 2a is made of a casting, it can be provided with high rigidity and high durability. Further, since each part is screwed from the indoor side, each part can be protected from theft from the outside. Further, even if rainwater passes through the water stop vent 8 and enters the vent hole 3 due to considerably strong wind and rain, the rainwater is naturally drained outside the room along the inclined bottom surface 29. And this ventilation block 1
a, the water blocking vents 8a, 8 shown in FIGS.
It goes without saying that b can be applied.

The block body used in the present invention is:
Not limited to the above-mentioned aluminum plate or cast product, for example, a thick glass frame having a certain strength or more, polycarbonate or other synthetic resin having high mechanical strength (eg, engineering plastic), or fiber reinforced plastic (FRP) ).

In each of the above embodiments,
Although the type of register in which the slide plate is slid laterally is illustrated as the ventilation amount adjusting unit, a type in which the slide plate slides rotationally may be used. Alternatively, for example, a butterfly valve type may be used.

[0027]

As described above, according to the present invention, a ventilation block having a ventilation hole is mixed and used in combination with a glass block. Can be ventilated through the body.

Further, since the water blocking portion is provided in the ventilation hole of the block body, it is possible to pass air but not water. Therefore, it can be suitably used for constructing an outer wall separating the room and the outside.
