Description

  The present invention relates to a ventilation material and a ventilation device using the ventilation material, and more specifically, for example, installed in a ridge portion of a ridge roof, so that rainwater and snow are not allowed to enter indoors in the case of wind, rain, and snow. The present invention relates to a ventilation material that is used as a building ventilation material that performs ventilation sufficiently, or a ventilation material that is installed in a ceiling board part under a house eaves or a draining part of a base, and performs ventilation of a building, and a ventilation device using the ventilation material. .

  In recent years, many buildings to be constructed have a ventilation layer between the outer wall and the inner wall for letting out moist air from the room permeating through the wall to the outside. It has a structure with a vent. The air flowing into the building from the ventilation layer and the eaves vent on the leeward side flows out through the attic. For this reason, ventilators or ventilators having various shapes are conventionally provided in the attic.

  FIG. 5 shows a typical example of a conventional building ventilation material. Two plastic plate-like ventilation materials 12 and 13 having a large number of thin ventilation holes 15 penetrating in the width direction are fastened by a joining tape 14. The opposing surfaces of the ventilation members 12 and 13 are inclined so that they can be bent in an inverted V shape from the tape 14 (Japanese Patent Laid-Open No. 2-272153). This ridge ventilator is attached to the roof ridge in an inverted V shape, so that the indoor moist air from the vents in the attic can be removed from the inside (indoor side) opening of the vent 15 to the outside (house). Outer) It is passed through the opening and discharged to the outside.

  The ventilation holes 15 in this building ventilation material are formed sufficiently long in the width direction, that is, in the direction perpendicular to the length direction of the ventilation materials 12 and 13, and are arranged in an inverted V shape in the building so Together, rainwater and snow that blows up along the roof can be prevented from entering the room.

  As a manufacturing method of the plastic air-permeable materials 12 and 13, a plurality of plastic plates in which vent holes penetrating in the width direction are continuously provided over the entire length are laminated, and the laminated plastic plates are cut with a heat cutter, A method (Japanese Patent No. 2683109) is known in which the cut surface is fixed by thermal fusion.

  In this manufacturing method, the upper and lower plastic plates are heat-sealed simultaneously with cutting by fusing with a heat cutter, but the work moves relatively at a constant speed while keeping the heat cutter at a constant temperature. It takes time to work. That is, if the temperature is raised too much to shorten the cutting time or the cutting speed is increased, melting will occur excessively and a clean finish cannot be expected.

In the case of the building ventilation material, a certain level of surface strength is required because the building tiles are placed on the building ventilation material. It is necessary to use a thick plastic plate. However, if the opening forming portion of the plastic plate is made thick, the opening area of the ventilation path is reduced correspondingly, resulting in a problem that the ventilation performance is lowered and the weight is increased.
JP-A-2-272153 Japanese Patent No. 2683109

  The present invention has been made to solve the above-described problems in the prior art, and is a plastic ventilation material used for the above-mentioned applications, having sufficient surface strength, good ventilation performance and rainproofing. Another object of the present invention is to provide a ventilation material that has snowproof performance and can be easily manufactured at low cost, and a ventilation device using the ventilation material.

  The invention described in claim 1 for solving the above-mentioned problem is characterized in that it comprises a loop layer formed into a flat plate shape by entwining a large number of hard plastic loop wires each having a continuous loop formed therein. It is.

  Preferably, a support layer obtained by flatly crushing the loop layer is disposed on the upper surface and / or the lower surface of the loop layer. The loop in the loop layer may be appropriately pressed and deformed.

  In addition, a plurality of any of the above ventilation materials may be laminated to form a ventilation material, and a plastic plate may be fixed to the upper surface and / or the lower surface of the ventilation material.

  The invention according to claim 6 for solving the above-mentioned problems is a ventilation device using any one of the above-mentioned ventilation materials and molding them into a mountain shape.

  The ventilation device can be configured by connecting the pair of ventilation members in a mountain shape via the support layer and / or a plastic plate, and in that case, the support layer / or the upper surface of the pair of ventilation members. The plastic plate is one continuous support layer or plastic plate, and can be configured to be bendable at an intermediate portion thereof.

  The air-permeable material according to the present invention has sufficient strength and air permeability to be composed of a loop layer constituted by a large number of loops, and when the support layer and / or the plastic plate are provided, the strength and shape retention are further increased. Thus, sufficient surface strength is obtained, and sufficient air permeability is ensured as a ventilation material. Further, in the loop layer, since the loops are randomly entangled, there are many inflection points, and there is an effect that the entry of rain and snow is reliably prevented.

  The best mode for carrying out the present invention will be described with reference to the accompanying drawings. The ventilation material 1 according to the present invention includes a loop layer 2 constituted by a loop wire 10.

  The loop layer 2 is formed by processing a hard plastic wire material such as polypropylene so that a large number of the loop wire materials 10 continuously formed into loops are entangled and bonded or welded together to form a flat plate. Usually, the flattening is performed by heating and pressing, so that the loop is deformed. However, since the ventilation space 8 is sufficiently retained, the air permeability is not hindered.

  The pressure strength of the loop layer 2 can be adjusted by selecting the type and thickness of the plastic wire used. It is also possible to adjust the ventilation performance by selecting the diameter of the loop.

  In the illustrated example (FIG. 1B), the support layer 3 in which the loop is completely crushed is provided on the upper surface and the lower surface of the loop layer 2. The support layer 3 contributes to the improvement in strength and shape retention of the loop layer 2, and is integrally fixed to the upper surface, the lower surface, or both surfaces by welding, adhesion, or the like. As the loop wire constituting the support layer 3, a material having a smaller diameter than the loop wire constituting the loop layer 2 may be used. In addition, the arrow A in FIG.1 (B) has shown the ventilation direction.

  Further, in the illustrated example (FIG. 1B), the plastic plate 4 is fixed on the support layer 3 in order to further increase the strength and the shape retaining force. As the plastic plate 4, for example, a plate in which air passages extending from one end surface to the other end surface are provided in parallel, and this is bonded and fixed to the upper surface and the lower surface of the loop layer 2.

  The embodiment shown in FIGS. 2 and 3 constitutes a building ventilation device using the ventilation member 1 according to the present invention (in FIGS. 2 and 3, the frontmost loop is shown for convenience of grasping the configuration. The inside is shown as blank, but in reality, the interlaced loop on the back side can be seen (the same applies to FIGS. 1B and 4).

  In the embodiment shown in FIG. 2, a pair of ventilation members 1 each having a support layer 3 disposed on the upper and lower surfaces of the loop layer 2 are connected via the support layer 3 on the upper surface. In the illustrated example, the support layer 3 on the upper surface is a single continuous layer, and two loop layers 2 are fixed to the support layer 3 at intervals, and the inner end side 2a of each loop layer 2 is obliquely crushed. Has been. Thus, the inner end side 2a is crushed and a space portion is formed there, but this space portion becomes the air introduction portion 5 in the back of the shed discharged from the ridge opening.

  In addition, as a modification of this embodiment, while forming the air introduction part 5 by crushing the middle part of one ventilation material 1, the whole is formed, bent from the middle crushing part, and as shown in FIG. A method of forming the shape is also conceivable.

  The embodiment shown in FIG. 3 uses a ventilation member 1 including a plastic plate 4, and the plastic plates 4 and 4 on the upper surface of the pair of ventilation members 1 and 1 are one continuous large plastic plate. The middle part can be bent. And it is comprised so that it may form a mountain shape by bending from the middle bending part 6. FIG. In that case, the loop layers 2 and 2 of each ventilation material 1 and 1 are separated so that a space, that is, an air introduction portion 5 is formed between the butted portions.

  These ridge ventilation devices are arranged so as to cover the ridge opening (the air introduction part 5 is located on the ridge opening), and are fixed to the base plate by nailing or the like. In addition, the code | symbol 7 in FIG. 3 has shown the foaming plastic cushion material, and it adheres and fixes to the plastic plate 4 of a lower surface side as needed. The cushion material 7 is in close contact with the base plate surface while being properly crushed, and prevents the rain and snow blowing up from below from moving into the back of the hut.

  Although the loop layer 2 in the above embodiment is a single layer, a plurality of these layers may be stacked. In that case, for example, a configuration in which the plastic plate 4, the support layer 3, the loop layer 2, the support layer 3, the loop layer 2, the support layer 3, and the plastic plate 4 are stacked and integrated in this order is considered (FIG. 4A). ). Alternatively, the intermediate support layer 3 may be omitted and the loop layers 2 may be bonded and welded together, or a configuration in which the plastic plate 4 is sandwiched between them (FIG. 4B) may be employed.

  The air-permeable material 1 according to the present invention has sufficient strength and air permeability to be composed of a loop layer 2 constituted by a large number of loops, and further has a support layer 3 and / or a plastic plate 4 to provide sufficient strength. Surface strength is provided, and sufficient air permeability is ensured as a ventilation material. Further, in the loop layer 2, since the loops are randomly entangled, a large number of inflection points are formed, so that the entry of rain and snow is reliably prevented.
