Description

  The present invention is a blindfold panel having ventilation and blindfolding, and by integrating the entire panel surface, even a panel using a relatively thin material has mechanical strength, and has security. A raised blindfold panel is provided. The present invention also provides a windproof panel that can be used for a detached house, a windbreak fence standing on the boundary of a road, and the like.

  The purpose of the surface lattice attached to the outside of the window of the house and the fence attached to the boundary with the adjacent land may be for the purpose of crime prevention or blindfolding, but it is more transparent and has sufficient ventilation. It is perfect if there is sex, but there are many fences that are not so.

  A window frame for crime prevention is attached to a general house, and a plurality of aluminum extruded shapes are combined in a vertical or horizontal direction, or a diagonal shape is generally used. In the sense of crime prevention, the mechanical strength of the aluminum shape fins is weak, and there is a disadvantage that it is not very useful.

  In addition, there are many fences in which a plurality of strip-shaped aluminum shapes are combined in the vertical or horizontal direction for the purpose of blindfolding with the adjacent land, but they are fixed to the outer frame and integrated to form the shape as a fence. In addition, when ventilation is necessary, it is attached with a gap between adjacent aluminum profiles.

  However, it is necessary to consider ventilation and strength in addition to crime prevention in such a configuration, but since the aluminum shape fins used are not connected, the mechanical strength can be individually increased with strip-shaped fins. It was necessary to secure it, and naturally it was necessary to use something with a thick wall or one with a large cross-sectional performance. Still, there is no fence with sufficient crime prevention.

  For example, a blindfold fence has been proposed that is easy to carry into the construction site, etc., can be constructed accurately and efficiently, is excellent in strength, and has a good appearance. , Composed of a column and a plurality of fixtures mounted in series on the front surface of the column, and a plurality of blades mounted in parallel in the vertical direction between the front surfaces of the column. Inclined pieces inclined obliquely downward toward the rear are formed on the upper and lower edges of the front plate pieces, and upper and lower attachment pieces refracted downward are formed at the rear ends of these vertically inclined pieces. The blade is installed between the front surfaces of the fixtures mounted on the front surfaces of the right and left struts, and the upper and lower mounting pieces are inserted into the upper and lower support grooves in the upward opening of the fixture. And a fence is configured (see Patent Document 1).

  In addition, a protective fence has been proposed that is well lit and ventilated, can provide a blindfold function, has sufficient strength, and is excellent in crime prevention. This protective fence is provided on both sides of the cylindrical support section. A large number of lattice members comprising a plastic lattice member main body integrally projecting a pair of blades, and a metal stripe toughly inserted into a cylindrical support portion of the lattice member main body. Are arranged in such a manner that adjacent blade blade tips adjacent to each other between a pair of frame members perpendicular to the longitudinal direction of the lattice member form a certain gap in the blade thickness direction and overlap in the blade width direction. The both ends of the stripe strength of the lattice member are fixed to the both frame members (see Patent Document 2).

  Furthermore, there has been proposed a blind fence that can be installed continuously on both flat and sloping terrain, and this blind fence is constructed by axially mounting a large number of horizontal rails on a plurality of parallel vertical rails. The fence can be tilted according to the parallel movement of the vertical beam, and it can be installed on the column via a bracket so that it can be tilted. Equally spaced fins are arranged by providing blindfold fins and covering fins that cover the pivoting portions so as to be superposed (see Patent Document 3).

  By the way, a blindfold fence having a windbreak function and a windbreak fence installed on a road or the like are preferably so-called windbreak fences that receive wind over the entire wind receiving surface of the fence from the viewpoint of blocking wind. . However, if it is a windbreak fence that completely blocks the wind, the wind pressure load increases, so there is a risk of collapsing, so it is necessary to reinforce the surface panels and struts that form the wind receiving surface, and as a result, it is expensive. It was.

  Therefore, through holes or gaps are provided on the wind receiving surface, wind pressure is released from the through holes or gaps to reduce the wind pressure load without receiving the total wind pressure, and the improvement of the strength of the support is moderately suppressed. A technique for blocking this has been proposed. For example, a grid fence (see Patent Document 4) in which panels straddling between the upper and lower body edges are attached to the grid fence at appropriate intervals, and through holes are provided in the upper and lower portions of each panel, and the columnar material in the height direction or the horizontal In a transflective windbreak fence that is disposed in the direction and has a gap between the columnar members, a windbreak fence (see Patent Document 5) in which the columnar members are rounded has been proposed.

  In addition, in order to suppress the noise caused by the wind when the wind passes from the outside to the inside through the gap provided between the louvers, a plurality of louvers are arranged in parallel at a predetermined pitch within the fence frame. In a blindfold fence with a ventilation gap between them, a projection is formed on the wind receiving surface of each louver to divert the wind and guide it to the gap, and deflects the airflow diverted by the projection A blindfold fence in which a deflecting plate portion is formed has been proposed (see Patent Document 6).

JP 2004-36298 A Japanese Patent Laid-Open No. 9-100654 JP 2002-81229 A JP-A-6-264419 JP-A-9-67810 Japanese Patent Laid-Open No. 2000-54642

  However, the blindfold fence proposed in Patent Document 1 is blindfolded, translucent, and ventilated. However, in order to make individual fins apart and having sufficient strength, the cross-sectional performance of the molded body It is necessary to raise it and becomes an expensive fence. In any case, there is a problem with crime prevention.

  Further, the protective fence proposed in Patent Document 2 has such a structure because it cannot be expected to be strong enough in plastics itself, and it is necessary to insert a core into the center of the slats from the cut-off point of crime prevention. . In order to further improve the crime prevention, the strength of the plastics and the aluminum profile will be further increased, resulting in an expensive fence.

  Furthermore, the blind fence proposed in Patent Document 3 can cope with the inclination as a fence. However, like the blindfold fence and the protective fence proposed in Patent Documents 1 and 2, individual fins are formed independently. Since it is a body, there is a problem in strength, and it cannot be used in a place where it is used as a fence that requires blindfolding and crime prevention.

  As mentioned above, fences used for windows of detached houses, apartments, condominiums, etc., and borders with neighboring areas are for the purpose of blindfolding, and we want to consider crime prevention and ventilation. However, even if the fence is breathable, there are many fences that are not crime-proof, that do not allow wind to pass through even if it is highly blindfolded, that the light is blocked, or that lack the landscape. . Therefore, there has been a demand for a blindfold fence that satisfies all of crime prevention, breathability, blindfold, price, and the like.

  In addition, the lattice fence proposed in Patent Document 4 and the windbreak fence proposed in Patent Document 5 have a through hole or a gap formed in a front view, so that a blinding effect cannot be obtained. Passed through the holes or gaps without changing direction, so the wind would reach from the fence far into the site. Therefore, plants planted in the vicinity of the fence are directly exposed to the wind and are adversely affected by scattering flowers, etc., and the people near the fence are exposed to the wind and make it uncomfortable, and sand, garbage etc. It was sprayed to the vicinity.

  Moreover, although the blindfold fence proposed by patent document 6 can acquire the blindfold effect, the problem that the wind as described above reaches the inside of the site has not been solved. In other words, the wind blown on the fence is divided into two at the upper part of the projection, and then the direction of the wind is changed at the deflecting plate, but it is provided to prevent noise, so the direction of the wind changes significantly. It is not carried out and goes straight through the gap. Therefore, the wind reached the inside of the site and caused the above-mentioned harmful effects.

  As described above, in the conventional windbreak fence, there is a problem that the wind passes far through the fence, and it is possible to obtain a blindfold effect, and the wind that has passed through the fence does not reach far away. Was demanded.

By setting the aperture ratio and the area of the aperture, It is possible to balance the wind pressure load received by the windproof panel and the strength.

First, the blindfold panel will be described.
The blindfold panel of the present invention is such that, as in the conventional lattice fence or blindfold fence, the individual molded bodies are not separated, and a plurality of perforated slopes and slopes without holes are alternately configured and integrated or connected. If you want to reduce the cost significantly, you can make a three-dimensional blindfolded panel with a sawtooth cross-section by punching a metal plate into a strip with a press and then roll forming it, or the entire blindfolded panel It is composed of a molded body so that parts with multiple openings in it and parts without openings are alternately banded, and it has mechanical strength for crime prevention and breathability and excellent blinding, There is a great blindfold panel fence that is durable.

  An extruded shape of an aluminum extruded shape having a plurality of L-shaped or L-shaped cross-sections having a plurality of holes on one side and a surface having no holes on the other side. It has been used in the past by making the concavities and convexities of both ends into a fitting shape, connecting the surfaces with and without the perforations alternately, and forming a frame material around them. It is intended to solve the shortcomings of the blindfold panel fence.

  As a method of configuring a blindfold panel by roll processing or press processing with a thickness of 0.3 mm to 2.0 mm made of stainless steel, aluminum, plated steel plate, etc., assuming that the coil width of the metal plate is 600 mm to 1210 mm In this case, the non-open hole portion is 10 mm to 100 mm, and a plurality of open holes are formed in a band shape in the length direction from 10 mm to 100 mm next to the non-open hole portion. After sequentially performing such a configuration, a blindfold panel having a sawtooth cross section is formed at a stretch by roll forming.

  In this case, a plurality of perforated surfaces and non-perforated surfaces are adjacent to form separate slopes. The non-perforated slope is formed on the vertical surfaces of the front and back of the blindfold panel with a width of 20 to 60 mm. The open slope is formed by connecting the non-open slope and the non-open slope formed on the vertical surfaces of the front and back of the blindfold panel horizontally or diagonally with a length of 10 to 50 millimeters. The shape of the hole on the open surface can be freely selected from round holes, square holes, elliptical holes, and long holes depending on the user's preference, and the opening ratio may be approximately 20 to 50 percent. The air permeability is as good as possible, but it is determined in consideration of the thickness, material, shape and strength of the plate material to be used. Further, the aperture ratio of the apertured surface can be made smaller or larger depending on the degree of blinding required, but is usually about 20 to 50 percent.

  In the case of an aluminum extruded profile, the profile has a substantially L-shaped cross section or a shape in which a plurality of L-shaped sections are continuous, and each side of the L-shaped molded body has a plurality of aperture slopes in a strip shape. It is composed of a non-perforated slope, and a plurality of the molded bodies are connected and attached to the frame material. At this time, the concavity and convexity connection portions of both ends of the cross section are in a fitting shape, and the blindfold panel When configured as, it is configured to strongly resist horizontal loads from the side.

  The width of the non-perforated slope may be 20 to 60 millimeters, and the width of the perforated slope may be 10 to 50 millimeters. The shape of the hole on the open surface can be freely selected depending on the preference, such as a round hole, a square hole, an elliptical hole, or a long hole, and the opening ratio may be about 20 to 50 percent at this time.

  A plurality of extruded aluminum extruded shapes and non-perforated aluminum extruded shapes are alternately connected and attached to the outer frame. Constitute. In this configuration, it is advantageous to have a connection structure in which individual fins can move freely, since it can be freely configured by changing the position where it is stopped by the lateral outer frame material in one blindfold panel. is there.

  In the case of plastic extrusions, L-shaped units are formed in L-shaped units, and a plurality of holes are formed on one of the slopes, as in the case of aluminum extrusions. The concavity and convexity connecting portions of both ends of the cross section have a fitting shape, and a plurality of them are connected to form an integral panel. Also in this case, the aperture ratio of the perforated surface can be reduced or increased depending on the degree of necessity for blinding and ventilation.

  When it is configured by mixing aluminum and plastic extrusions, it can be configured to a certain degree of transparency and blindness depending on the combination, making it an ideal blindfold panel, but due to the difference in weather resistance of the material, Since it may become a bad landscape due to aging, it may be composed only of extruded plastics.

  Furthermore, not only a combination of a slope with a hole and a slope without a hole, but also an L-shaped cross section in which two slopes are not opened when it is desired to increase the blinding of a part with a planar panel as in claim 3. These shapes may be made continuous, or conversely, L-shaped shapes having a plurality of openings on two slopes may be made continuous to increase the ventilation.

  When you want to make a blindfold panel that has light and is blindfolded and has excellent functionality, it is possible to construct an aluminum extruded shape and an extruded shape of translucent plastic alternately to create a highly transparent blindfold panel. However, in this case, it is inevitable that the blinding property is somewhat inferior.

  Of course, plastic materials such as vinyl chloride, acrylic, polycarbonate, and polyester can be selected from plastics, such as transparent, opaque, but vinyl chloride emits pollutants when incinerated. Acrylic has good weather resistance but is easy to break. Polycarbonate is an expensive material and difficult to use. Translucent to opaque materials such as polyethylene and polypropylene are less polluted and less expensive, but because of the large linear expansion of the resin, when configuring as a panel, the shape and mounting method should be used to prevent distortion. You need to be careful.

  As described above, the present invention has studied how to construct a blindfold panel having good breathability, blindfolding, and translucency and having high crime prevention properties in a good landscape.

  For the proposition of crime prevention, a stainless steel plate or a plated steel plate having a thickness of 0.5 mm is used, and a blindfold panel having a sawtooth cross section is formed at a stretch by roll forming. At this time, a slope with a plurality of apertures and a slope without a hole are sawtooth-like and adjacent to each other to form separate slopes. If such a mass production system can be laid, it will be possible to provide it at a low price even if it looks high quality. Further, by connecting the molded body having an L-shaped cross section with a plurality of apertures and an inclined surface, they are united to form a blind cover panel with considerable mechanical strength and high security.

    The mechanical strength can be adjusted to some extent by the dimension of the protruding width, which is the thickness of the panel by the combination of L-shapes, so that the fence is excellent in cost performance. Furthermore, since the whole is united as a panel, it will not be damaged unless a very intense concentrated load is applied to one point. Therefore, in normal use, no problem occurs and the crime prevention property is extremely excellent.

  The air permeability is desired to be secured while maintaining the blindfold and crime prevention properties. However, if the aperture surface is configured vertically, the blindfold is reduced, which is not preferable. Therefore, it is preferable to make the cross section wider by providing an angle to the slope of the perforation to ensure ventilation, but these are not limited.

  As for translucency, there is a contradiction between increasing the aperture ratio so that light can be taken in as much as possible and reducing the blindfold, so that the light-transmitting plastics and the slope with the aperture It is better to construct a slope with no. At this time, it is preferable to form a blindfold panel with a single piece of plastic. However, if a plastic body such as an L-shape is continuously formed, there is a high possibility of causing a problem in connection strength, and attention is required. A combination of a plastics molded body and an aluminum molded body is advantageous because when the aluminum is deformed, the plastics bite into the aluminum and are firmly connected.

  The blindness is basically determined by the ratio of the opening ratio of the slope with an opening to the slope without an opening, but by changing the combination of the L-shaped shape, size, and opening ratio freely. It can meet customer needs.

Next, the windproof panel will be described.
In the windbreak panel according to the present invention, a plurality of inclined surfaces are formed on the wind receiving surface, and a through hole is formed on the inclined surface. And since a wind pressure reduces in a wind-receiving surface by a wind passing through a through-hole, and the through-hole is formed in the inclined surface, the direction of the wind which passes a through-hole can be changed. As a result, the wind passing through the windbreak panel does not go straight, but changes its direction to approach the windbreak panel and does not reach the inside of the site. This inclined surface may be in a vertical direction (downward or downward direction toward the site side) or in a horizontal manner (right or left direction toward the site direction). Good. Among these inclined surface modes, since the influence on nearby planting and the like is small, it is preferable to form a slanting downward direction toward the site and change the wind direction to a sloping upward direction.

  In addition, the inclined surface in which the through hole is formed may be linear or arcuate. In addition, the “site” in the “site side direction” mentioned above is the site of the house in a detached house, etc., the road side site in the road, and means the land on the side where wind is to be protected by the windproof panel. Is.

The through-hole of the inclined surface preferably has an opening ratio of 20 to 50% on the inclined surface. If the opening ratio is less than 50%, the effect of sufficiently reducing the wind pressure load is small, and the opening ratio exceeds 70%. And windproof effect is reduced. Further, the area of the through hole is preferably 1 to 3 cm ^{2. If} the area of the through hole is less than 1 cm ² , the effect of sufficiently reducing the wind pressure load is small, and if the area of the through hole exceeds 5 cm ² , the windproof effect is small. Become. And an aperture ratio and the area of a through-hole are suitably selected in the above range.

  For example, when the angle of the inclined surface is formed obliquely downward toward the site, the range of 5 to 45 degrees is preferable with respect to the horizontal plane, and the range of 15 to 30 degrees is more preferable. If the angle of the inclined surface is less than 5 degrees, the effect of sufficiently reducing the wind pressure load is small, and if the angle of the inclined surface exceeds 45 degrees, the windproof effect is reduced.

  A guide inclined surface that guides the wind to the inclined surface can be formed adjacent to the inclined surface in which the through hole is formed. The guide inclined surface can reduce the wind pressure load and can smoothly guide the wind to the through hole by changing the direction of the wind. The inclined direction of the guide inclined surface is selected corresponding to the aspect of the inclined surface in which the through holes are formed (four aspects described above). For example, when the inclined surface in which the through hole is formed is obliquely downward toward the site side, the inclined surface is formed obliquely upward toward the site side. The guide inclined surface may be linear or arcuate, but a shape that can smoothly guide the wind to the through hole is preferable.

  The wind-receiving surface may be formed by a single panel body, or may be formed by a plurality of band-shaped members provided in a continuous manner. When forming with one panel body, the panel which integrally formed the above-mentioned inclined surface and guide inclined surface is used. When the band member is continuously formed, the above-described inclined surface and guide inclined surface are integrally formed on the band-shaped member. The belt-like member may be a belt-like member in the horizontal direction or a belt-like member in the vertical direction. That is, the belt-like member is formed by continuously connecting the belt-like belt-like members in the horizontal direction in the vertical direction, A band-shaped member is formed continuously in the left-right direction. Accordingly, the belt-shaped member has two modes of the horizontal direction and the vertical direction, and the inclined surface has four modes of obliquely downward, obliquely upward, obliquely leftward, and obliquely rightward. Can be taken.

  In addition, the arrangement of the inclined surface and the guide inclined surface in the belt-shaped member is not particularly limited. For example, when the inclined surface is formed obliquely downward and the guide inclined surface is formed obliquely upward, the inclined surface is formed in the upper part. In addition, the guide inclined surface may be formed in the lower portion, or conversely, the inclined surface may be formed in the lower portion and the guide inclined surface may be formed in the upper portion.

  The inclined surface and the guide inclined surface can be formed of a light-transmitting material. With such a configuration, planting can be exposed to sunlight without being exposed to the wind. In addition, the matter demonstrated in the blindfold panel mentioned above is all applicable, unless the effect | action of a wind-proof panel, ie, the effect | action of changing the direction of a wind, is impaired.

  The windbreak panel according to the present invention can be used for a blindfold fence, a windbreak fence, an outdoor partition, and the like, and is particularly suitable for a windbreak fence installed in a place where strong winds are desired to be reduced.

[Specimen]
As the test body 80, the windproof panel demonstrated in 1st Embodiment of the windproof panel was used. The windbreak panel has a height of 114 cm, a width of 120 cm, 21 strip members 30, an angle of the inclined surface 31 of 20 degrees, a width of the inclined surface 31 of 3.5 cm, and an opening in the inclined surface 31 of the through hole 35. The rate is 40%, and the area of the through-hole 35 is 1.6 cm ² .

[Test method]
The test body 80 is fixed at a distance of 91 cm from the air outlet 76 of the wind generating device 71, and the wind generating device 71 blows a wind of 8 m / s wind toward the test body 80. The wind speed and direction of the space were detected with an ultrasonic anemometer 73. The detection location is a location indicated by a black circle in FIGS. 14 and 15. The outlet 76 of the wind generator 71 was 120 cm high and 120 cm wide. 14 and 15, “H” indicates the height (114 cm) of the test body 80, and the distance from the test body 80 is displayed as the distance from the test body 80.

[Test results]

[Evaluation]
The following was found from the test results.
1. It was found that the wind was flowing upward at an angle of 70 to 77 degrees on the rear surface of the windproof panel.
2. At the position of 1 / 5H (228 mm) rearward of the windproof panel, the wind speed flowing almost to the wake side could not be measured.
3. The wind speed distribution behind the windbreak panel tends to flow upstream so as to be drawn in due to the effect of rising upstream of the windbreak panel.
4). Furthermore, since the specimen is located at a position of 91 cm from the air outlet of the wind tunnel, and the cross-sectional shape of the air outlet is □ 120 × 120 cm, the height of the specimen 80 is as large as 114 × 120 cm. As a result, it flowed upward from the front (upstream part) of the test body 80.

  From the above results, the most part of the wind that passed through the test body 80 has its wind direction suddenly changed upward, and the wind speed is faster than before the test body 80, and 5 / 5H. Almost no wind was observed at a distance of (120 cm) even at a height of 6 / 5H (137 cm). This is considered to be due to the fact that the through-hole 35 is formed on the inclined surface 31 inclined in the obliquely downward direction toward the site side direction, and is guided in the obliquely upward direction that is the axial direction thereof. It is considered that the wind speed was increased because the winds of no. Therefore, it was confirmed by the test body 80 that the wind did not reach the back of the site.
