Description

  The present invention relates to a tide plate and a tide fence that are installed along a coastline and prevent seawater droplets containing sea salt particles generated by wave splashing from flying to surrounding private houses.

  As a fence installed for the purpose of windproof or snowproof, for example, Patent Document 1 discloses a snowbreak fence formed by attaching a folded plate-shaped snowbreaker plate having a large number of small holes to a column. Such a snow fence has sufficient mechanical strength to withstand strong winds and is effective in preventing snow in the event of a snowstorm, etc. It was inappropriate.

  On the other hand, for example, Patent Document 2 discloses a fence panel formed in a nonwoven fabric shape using a fibrous synthetic resin as a device capable of trapping splashes.

Japanese Utility Model Publication No.59-92714 JP 61-294072 A

  However, the fence panel described in Patent Document 2 is effective for capturing splashes, but has a low mechanical strength because it is formed into a nonwoven fabric from a fibrous synthetic resin. It was unsuitable for use as a fence panel installed on the coastline where strong winds might blow.

  The present invention has been made in view of the above problems, and provides a tide plate and a tide fence that have both high mechanical strength and good capture performance.

That is, the present invention is a tide plate that is attached to struts erected at an appropriate interval along the coastline and captures seawater splashes contained in the wind blowing from the sea side,
A perforated plate made of a rigid material such as a metal having a large number of ventilation holes and a filter formed in a non-woven shape with chemical fibers, natural fibers or a mixture of them are laminated, and the filter comprises the perforated plate. The filter is sandwiched between the perforated plate and the breathable holding member, and the perforated plate and the holding member are detachably connected, The holding member is a tide plate made of a mesh panel formed in a net shape with a large number of wires .

With the above configuration, the wind blown from the sea side passes between the mesh panel wires and permeates the filter, so when the wind permeates the filter, seawater splashes contained in the wind adhere to the filter and are captured. Is done. By laminating a filter on a perforated plate made of a rigid material, the perforated plate can be used as a reinforcing member to obtain sufficient mechanical strength, and droplets can be captured by a filter having excellent capturing performance. Therefore, it is possible to combine high mechanical strength and good capturing performance.
In addition, since the filter can be detached from the perforated plate by being detachably attached to the perforated plate, even when the filter is clogged, the filter can be replaced with a new one or washed. Can be used again.
In addition, the filter is sandwiched between the perforated plate and a breathable holding member, and the perforated plate and the holding member are detachably connected to each other. It is not necessary to attach the filter directly to the perforated plate. By attaching the perforated plate to the support column, the filter can be removed without removing the perforated plate, and the filter can be easily replaced.
In addition, since the holding member is made of a mesh panel formed in a net shape with a large number of wires, when the wind blown from the sea side hits the tide plate, the wind easily passes between the wires of the mesh panel. And ventilation in the filter is promoted.

  Further, in the tide plate of the present invention, it is preferable that the crest and trough extending in the horizontal direction are bent and formed in a wave shape in which the crest and trough are alternately connected in the vertical direction. Thereby, the mechanical strength of the tide plate can be further improved and the surface area of the tide plate can be increased. Therefore, high mechanical strength can be obtained, and the contact area with the wind blowing from the sea side can be increased and effective capture can be performed.

Further, the present invention relates to a tide fence in which a tide plate that captures seawater splashes contained in the wind blowing from the sea side is attached to a stanchion in which a plurality of support pillars are installed at appropriate intervals along the coastline. the tide plate, a number of ventilation holes perforated plate made of a rigid material such as metal having, chemical fiber, and a filter formed on the nonwoven natural fibers, or they were mixed fibers were laminated, the tide Plates are provided in the front and back in two rows with a predetermined interval in the front-rear direction, and in several stages with a predetermined interval in the vertical direction, respectively, and a front row of tide plates and a rear row of tide plates are provided. The tide fence is characterized by being arranged in a staggered manner with a predetermined pitch shifted from each other in the vertical direction .

With the above configuration, the wind blown from the ocean side passes between the wires of the mesh panel and passes through the filter, so when the wind passes through the filter, seawater splashes contained in the wind adhere to the filter and are captured. The By constructing the tide plate by laminating a filter on a perforated plate made of a rigid material, the perforated plate can be used as a reinforcing member to obtain sufficient mechanical strength, and it can be splashed by a filter with excellent capture performance. Therefore, the tide plate can have both high mechanical strength and good capture performance.
The tide plates are provided in two rows in the front and rear direction with a predetermined interval in the front-rear direction of the support column and in several stages with a predetermined interval in the vertical direction, respectively. The tide plates are arranged in a staggered pattern with a predetermined pitch shift from each other in the vertical direction, so that the wind blowing from the sea side passes between the tide plates in the front row, and the speed increases when this wind passes between the tide plates In addition, the wind hitting the tide plate by this speed increase is guided between the tide plates in the front row, so that it is possible to prevent the wind from blowing upward.

  In the tide fence according to the present invention, the tide board is preferably laminated so that the filter faces the sea side. As a result, the tide plate does not obstruct the perforated plate when the splash of seawater is captured by the filter, and the unevenness of the filter surface becomes resistance to the wind blowing upward from below, and the seawater splash is overcome. Can be reduced.

  Further, in the tide fence according to the present invention, the tide plate is formed in a wave shape in which a crest and a trough extending in the horizontal direction are alternately connected in the vertical direction, and the trough is on the sea side. It is preferably attached so as to face. As a result, when the wind blowing from the sea side hits the mountain and flows into the valley, a strong turbulent flow occurs in the valley and the wind stays so that the ratio of the seawater splash contained in the wind is captured by the filter. Can be high.

  Further, in the tide fence according to the present invention, the tide plates are provided in two rows in the front and rear direction with a predetermined interval in the front-rear direction of the support column and in several stages with a predetermined interval in the vertical direction, respectively. The front row tide plates and the rear row tide plates are preferably arranged in a staggered manner with a predetermined pitch shift in the vertical direction. As a result, the wind blowing from the sea side passes between the tide plates in the front row, and the wind speed increases as the wind passes between the tide plates, and the wind hitting the tide plate is induced between the tide plates in the front row by this speed increase. Thus, it is possible to prevent the wind from blowing upward.

  In the tide fence according to the present invention, a transparent or translucent non-perforated plate or a perforated plate made of a rigid material such as a hard synthetic resin that covers the gap is attached between the bottom tide plate and the ground. It is preferable. Thereby, the sea side can be seen from the land side by a transparent or translucent non-perforated plate or perforated plate, and the state of the coastline can be viewed.

  Furthermore, in the tide fence according to the present invention, it is preferable that a wind-up receiver for guiding the wind toward the sea side is mounted on the uppermost tide board so as to protrude toward the sea side. As a result, even if the wind blown from the sea side hits the tide plate and blows upward, the wind blows up to the sea side by receiving the wind, so that the blown wind gets over the tide fence and goes to the land side. Intrusion can be prevented.

  According to the present invention, the tide plate can have both high mechanical strength and good capture performance, and can maintain good transmission performance even when used for a long period of time by replacing only the filter of the tide plate. Can continuously catch seawater splashes.

In the present embodiment, the perforated plate 4 has a porosity of about 42%, for example. In order to improve the mechanical strength, the perforated plate 4 is formed into a wave shape in which peaks and valleys extending in the longitudinal direction are alternately connected in the vertical direction. In the case of the metal perforated plate 4, weathering treatment such as hot dip zinc aluminum alloy plating is performed so as not to be corroded by sea salt particles or the like.

  The filter 5 is, for example, a synthetic fiber such as saran fiber or polyester fiber formed in a non-woven fabric shape, and has a continuous void 5a through which the wind formed by the gap between the synthetic fibers can be transmitted. Yes. The continuous air gap 5a is continuous with the surface of the filter 5 and communicates with a complicated direction like a maze. When the wind containing seawater splashes is transmitted, the seawater splashes contained in the wind are synthesized. It has the function of adhering to fibers and capturing. In this embodiment, the filter 5 is set to have a synthetic fiber of about 200 to 5000 denier, a bulk density of about 30 to 500 kg / m <3>, and a thickness of about 5 to 30 mm. For example, the product name “Saran Rock” manufactured by Asahi Kasei Life & Living Co., Ltd. is used.

  For example, the mesh panel 6 is formed in a grid-like wire mesh by combining wire rods so as to cross each other vertically and horizontally and fixing the intersections by resistance welding or the like. The mesh panel 6 is bent and formed into a wave shape in which crests and troughs extending in the longitudinal direction are alternately connected in the vertical direction so as to have substantially the same shape and size as the perforated plate 4.

  The tide plate 3 is formed by sequentially laminating a perforated plate 4, a filter 5 and a mesh panel 6, and a fixing metal fitting 7 is arranged on the mesh panel 6 side so that the bolt hole 7 a faces the bolt hole 4 b of the perforated plate 4. The bolt 8 is inserted into the bolt hole 7a of the fixing bracket 7, the filter 5 and the bolt hole 4b of the perforated plate 4 and tightened with the nut 9, and the mesh panel 6 is fixed to the perforated plate 4 with the fixing bracket 7, the bolt 8 and the nut.

The non-perforated plate 10 is attached to the support column 1 by fixing both side portions to the front wall 1a of the support column 1 through appropriate fixing means (not shown) such as bolts and nuts.

  The non-porous plate 10 is made of a transparent or translucent plate material made of a rigid material such as hard synthetic resin, for example, and can see the sea side (land side) from the land side (sea side). In order to improve mechanical strength, the non-perforated plate 10 is formed into a wave shape in which crests and troughs extending in the longitudinal direction are alternately connected in the vertical direction.

  Further, on the uppermost tide plate 3, an upright receiver 11 is attached in an inclined manner so as to protrude in the longitudinal direction along the upper end of the tide plate 3. The blow-up receiver 11 is attached to the support column 1 by fixing lower end portions on both sides to the rear wall 1b of the support column 1 through appropriate fixing means (not shown) such as bolts and nuts.

  The blow-up receiver 11 is composed of a non-porous plate made of a rigid material such as metal, and guides the wind blown upward against the tide plate 3 to the sea side. This prevents the wind that hits the tide plate 3 and blown upward from entering the land side over the tide fence. In the case of the metal blow-up receiver 11, weathering treatment such as hot dip zinc aluminum alloy plating is performed so as not to be corroded by sea salt particles or the like.

  The tide fence according to the present embodiment has the above-described configuration, and is installed along a structure such as a shoreline embankment.
