Description

  The present invention relates to a house construction material for constructing a framework of a vinyl house covered with a synthetic resin film, and a vinyl house constructed using the house construction material.

  Conventionally, an agricultural vinyl house constructed by stretching a sheet made of a resin film between a plurality of house construction materials is known.

  In addition, as the house construction material, there are metal pipe-like or plate-like materials, and examples of the plate-like material include a long strip plate-like bottom wall portion and left and right sides forming the long side of the bottom wall portion. It consists of left and right side wall portions formed by raising the end edges obliquely upward inward, and groove portions surrounded by these left and right side wall portions and the bottom wall portion, and an elastic locking member is attached to this groove portion, A film fastening material that clamps the synthetic resin film by this elastic locking member is known.

  As described above, since many metal construction materials are usually used for the house construction material including such a film fastening material, a rust preventive paint is used in order to prevent the occurrence of rust and improve durability. Some have been sprayed and have a rust-preventing film attached thereto, but recently, those using aluminum or stainless steel as a material to enhance the rust-preventing performance have become widespread.

  On the other hand, synthetic resin films for vinyl houses, which have been used in recent years, are made of house construction materials made of aluminum or stainless steel, although their weather resistance has been significantly improved and they can withstand use for several years. When used, film degradation commonly known as so-called “film burn” has been reported. If film burn occurs, it will be damaged in a short period of time (for example, about 2 years) or it will stick to the house construction material and cannot be peeled off.

  Therefore, as a result of investigating the phenomenon of film burn, it was found that it occurred in the overlapping part of the film fixing material for fixing the film and its peripheral part. Measures have also been proposed such as sticking from the top of the synthetic resin film that is fixed to the film (for example, see Patent Document 1).

Japanese Patent Laid-Open No. 2002-7840

  However, since the technique disclosed in Patent Document 1 is only a coping therapy and the tape application work is troublesome, drastic countermeasures are desired from the market.

  An object of the present invention is to provide a house building material that can solve the above-described problems, and a vinyl house using the house building material.

  (1) The present invention is a house construction material for constructing a vinyl house framework covered with a synthetic resin film, and the powder coating is applied to the surface of a metal member formed in a predetermined shape. Features.

  (2) In the above (1), the present invention is used to fasten the synthetic resin film, and forms a long strip-like bottom wall portion to which the back side is fixed, and a longitudinal side of the bottom wall portion. Film fixing with left and right side walls formed by raising the left and right end edges obliquely upward inward, and the left and right side walls and the bottom wall, and attached with an elastic locking member for clamping the synthetic resin film A house construction material consisting of a groove was used.

  (3) In the above (1) or (2), the present invention is a house construction material having a rough painted surface.

  (4) According to the present invention, in any of the above (1) to (3), the house construction material is powder-coated in green.

  (5) The present invention is a vinyl house constructed with the house construction material according to any one of (1) to (4) above.

  According to the present invention, the anti-corrosion performance is high, and the durability and weather resistance are improved. At the same time, the film burn phenomenon that has conventionally occurred when using a house construction material made of aluminum or stainless steel is produced at low cost. It can be effectively prevented.

It is an external view of the film fixing material concerning this embodiment. It is a figure which shows the attachment method of the synthetic resin film to the film fastening material concerning this embodiment. It is the figure showing the mode of reflection of the light in the conventional film fastening material surface and the film fastening material surface concerning this embodiment. It is a partial external view which shows an example of the vinyl house using the film fastening material concerning this embodiment.

  In recent years, aluminum (including aluminum alloy) or stainless steel with alumite processing that forms a thin oxide coating on the surface has become widespread as a house construction material. It has been found that a film deterioration phenomenon called “film burn”, which has hardly been a problem in a house construction material made of a steel plate subjected to a rust prevention treatment, occurs remarkably.

  Initially, there was a theory that film burnt was influenced by thermal conductivity, but as a result of intensive studies by the present inventors, it was found that the effect of light reflectance was great.

  In other words, the thermal conductivity of aluminum and stainless steel, where film burning occurs, is higher for aluminum (240W / m · K) than that of general iron (53W / m · K), but low for stainless steel (16W). / m · K).

  Therefore, it is difficult to think that the thermal conductivity has an effect, but as a common point of both, focusing on the fact that the reflectance is higher than that of the steel house building material, By reducing the rate, it was further confirmed that the occurrence of film burn was reduced to each stage by diffusely reflecting light instead of specular reflection.

  Therefore, in this embodiment, as a house construction material for constructing a vinyl house framework covered with a synthetic resin film, the surface of a metal member formed in a predetermined shape is subjected to powder coating, and the film The burn can be prevented as much as possible.

  Here, powder coating is also called powder coating, and is one of the baking coating methods for metal materials using powder paint. Powder coating is said to be resistant to scratching and excellent in durability and weather resistance because the coating film is relatively thick.

  Moreover, as a powder coating material used, the thing centering on the polyester resin which is harmless also to a human body etc. can be used conveniently.

  Further, the house building material to be powder-coated includes at least a film fastening material used for fastening a synthetic resin film. That is, the film fastening material is a member that directly contacts with the synthetic resin film, and the portions of the film where the film burns occur are overwhelmingly the polymerization sites with the film fastening material and its surroundings.

  The film fastening material includes a long strip-shaped bottom wall portion to which the back side is fixed, and left and right side wall portions formed by raising the left and right end edges forming the longitudinal side of the bottom wall portion obliquely upward inward, respectively. And a film fixing groove which is surrounded by the left and right side wall portions and the bottom wall portion and which is mounted with an elastic locking member for clamping the synthetic resin film. The elastic locking member is usually formed from a linear spring, but it is preferable to apply powder coating to the elastic locking member.

  Here, the elastic locking member is also one of the house building materials, and as the house building material, only such elastic locking members and members that are formed in a pipe shape or a plate shape to constitute the framework of the vinyl house can be used. For example, a band binding member that binds a so-called house band member for holding the covered synthetic resin film so as not to be blown or fluttered by wind is also included.

  Some of these band binding members are used by protruding into the soil around the vinyl house, and there is also a problem that it becomes easy to come out from the soil by powder coating and roughening the surface to increase the coefficient of friction. It becomes possible to prevent.

  By the way, it is desirable that the powder-coated surface is a rough surface. The degree of the rough surface is not particularly limited, but it is assumed that a large number of minute irregularities are formed so that sunlight is not specularly reflected but diffusely reflected.

  In addition, since the surface area of the whole painted surface is increased by making the surface rough, for example, the heat absorbed by the house construction material is difficult to cool, and it is possible to prevent a sudden decrease in the temperature in the house.

  The coating color is preferably green. That is, powder coating using a green powder coating is performed.

  Green is considered to be easy on the eyes, and at least does not adversely affect the color of the person working in or around the vinyl house. Also, since green is considered to have high sunlight absorption, It is also useful for preventing a decrease in temperature.

  Further, for example, ceramic fine particles can be mixed in the powder coating material, and a house construction material capable of irradiating far infrared rays when absorbing sunlight can be obtained.

  As far-infrared rays are also referred to as nurturing light, there are reports that it is effective for growing crops, so it can be expected to have a positive effect on agricultural products such as vegetables and fruits grown in the house.

  A vinyl house formed by using the house building material described above to form a framework, fixing a synthetic resin film with the above-described film fastening material, which is one of the house building materials, and covering the framework with such a film; By doing so, it is possible to suppress deterioration over time of the synthetic resin film as much as possible, and in particular, it is possible to effectively prevent a phenomenon called film burn.

  Hereinafter, an embodiment of a house building material according to the present invention will be described more specifically with reference to the drawings. In addition, although the case where this invention is applied with respect to the film fastening material used in order to fasten the synthetic resin film which coat | covers a vinyl house as an example of a house construction material is demonstrated here, this invention is applied. The house construction material is not limited to this. For example, it is formed into an elastic locking member that clamps a synthetic film by being attached to a film fastening material, a pipe shape, or a plate shape to constitute a framework of a vinyl house. The present invention can be applied to a band binding member that binds a member or a house band.

  FIG. 1 is a view showing the appearance of a film fastening material according to this embodiment, FIG. 2 is a view showing a method for attaching a synthetic resin film to the film fastening material according to this embodiment, and FIG. FIG. 4 is a view showing a state of light reflection on the surface of the film fastening material and the surface of the film fastening material according to the present embodiment, and FIG. 4 is an example of a vinyl house constructed with the film fastening material according to the present embodiment. FIG.

  As shown in FIG. 1, a film fastening material 1 according to the present embodiment is formed by using an aluminum member 2 that has been subjected to anodization, and the back surface of the film fastening material 1 constitutes a framework of a vinyl house. A long strip plate-like bottom wall portion 11 fixed to the left and right side wall portions 12 and 12 formed by raising the left and right end edges forming the longitudinal side of the bottom wall portion 11 obliquely upward inward, respectively, Film fixing groove for mounting an elastic locking member for clamping a synthetic resin film F (hereinafter simply referred to as “film F”) surrounded by the left and right side wall portions 12 and 12 and the bottom wall portion 11 and covering the vinyl house. 10 and.

  As shown in FIG. 2, the film fixing material 1 is inserted into the film fixing groove 10 by loosening the film F, and an elastic locking member 15 (for example, a predetermined swing width) The film F is clamped by the elastic locking member 15 and the side wall portions 12 and 12 of the fixing groove 10 by inserting the film-fed linear spring meandering in FIG. It is possible.

  Thus, since the film fastening material 1 concerning this embodiment can latch the film F with the elastic latching member 15, it can reduce material cost and manufacturing cost, and is one operation | work. Thus, the film F can be locked, and the workability of the locking work can be improved.

  In addition, as a raw material of the film fixing material 1, stainless steel can also be used suitably other than aluminum.

  As described above, the film fastening material 1 is a member in which the film F is in direct contact, and film burn is overwhelmingly generated at the polymerization site of the film fastening material 1 and the film F and in the vicinity thereof.

  In order to prevent the occurrence of such film burn, the surface of the film fastening material 1 according to the present embodiment is powder coated.

  The paint used for this powder coating is polyester, epoxy, acrylic, fluorine, styrene, vinyl acetate, urethane, polyethylene, polypropylene, polyamide, polycarbonate, phenol, alkyd The powder coating can be used. These are not only harmless to the human body, but also can reduce volatile organic substances (VOC) by 100%, can be recovered and reused, and have little industrial waste. It can be set as a film stop member without this.

  In this embodiment, in particular, a polyester-based powder known as a well-balanced paint that has a beautiful appearance, excellent weather resistance, excellent coating film hardness, and has no major drawbacks in performance among various powder paints. Paint was used.

  Further, as a method for coating the film fastening material 1, a powdery paint is applied to the film fastening material 1 to be coated using static electricity, and then baked. According to such a method, not only can a thick coating film be obtained in a single process, but also a lower cost and easier compared to the case where a tape or the like that cuts ultraviolet rays is applied from above the film F as in the past. It is possible to prevent film burn.

  By applying such powder coating, as shown in FIG. 1, a coating film 3 is formed on the surface of the aluminum member 2, and the coating film 3 forms a large number of minute irregularities on the surface of the film fixing material 1. It becomes a rough surface. And thereby, the film fastening material 1 concerning this embodiment reduces light reflectance, As a result, it becomes possible to prevent generation | occurrence | production of a film burn.

  That is, when the surface of the aluminum member 2 is not powder-coated as in the conventional film fastening material, as shown in FIG. 3 (a), the sun incident on the surface of the film fastening material from outside the vinyl house Most of the light I (hereinafter referred to as “incident light I”) is specularly reflected on the surface portion of the aluminum member 2 having a high light reflectivity, and thus the specularly reflected light R (hereinafter referred to as “reflected light”). R ”) hits the back surface of the film F, and film burn occurred.

  However, in the case of the film fastening material 1 according to the present embodiment, most of the incident light I incident on the surface of the film fastening material 1 is absorbed by the coating film 3 as shown in FIG. Thus, the light reflectance of the film fixing material 1 can be reduced, and further, the reflected light R reflected without being absorbed is diffusely reflected by the minute unevenness of the coating film 3, so that the film burn is effectively generated. Can be prevented.

  Thus, by applying powder coating to the surface of the film fastening material 1 which is one of the house construction materials, the rust prevention performance is high and the durability and weather resistance are improved. It is possible to effectively prevent the film burn phenomenon that has occurred when using the made film fastening material at low cost.

  Here, the degree of the rough surface by the powder coating is not particularly limited, but it is assumed that a large number of minute irregularities are formed so that sunlight is irregularly reflected without being specularly reflected.

  The particle size of the powder coating is desirably in the range of 0.01 to 100 μm. By setting it as this particle size, a suitable light-diffusion effect can be acquired.

  In the present embodiment, the paint color is dark green. That is, the film fastening material 1 is subjected to powder coating using a dark green powder coating. Since dark green is a color having a high light absorptance (low light reflectance), the light reflectance of the film fastening material 1 can also be reduced by adopting such a configuration. Moreover, green is considered to be easy on the eyes, and at least does not adversely affect the person who works in or around the vinyl house.

  Furthermore, the film fastening material 1 has a surface area of the film fastening material 1 increased due to the minute unevenness on the surface of the coating film 3 so that it can easily absorb heat from sunlight, and has an extremely high thermal conductivity. Is covered with the coating film 3 having a relatively low thermal conductivity, it becomes difficult for the heat once absorbed to be dissipated, so that it is possible to prevent a sudden decrease in the temperature in the vinyl house. In addition, about the fall prevention of the temperature in this vinyl house, a more remarkable effect can be acquired by making a coating color dark green like this embodiment.

  In the present embodiment, ceramic particles are mixed in the powder coating material so that far infrared rays are irradiated when sunlight is absorbed. This far-infrared ray is also called nurturing light, and it has been reported that it is effective for growing crops, so this configuration has a positive effect on agricultural products such as vegetables and fruits grown in the vinyl house. The effect which gives can be expected.

  In FIG. 4, an example of the vinyl house comprised using the film fastening material 1 concerning this embodiment is shown.

As shown in FIG. 4, in the vinyl house H, a plurality of film fastening materials 1, 1,... Are assembled at an appropriate distance in the vertical and horizontal directions. The films F, F,... Stretched between 1,... Are inserted into the film fixing grooves 10 of the film fastening materials 1, 1,. Film fastening material 1,1
, ... are locked.

  Thus, by constructing the vinyl house H using the film fastening material 1 according to the present embodiment, it is possible to suppress the aging degradation of the film F as much as possible. A vinyl house H that can be effectively prevented at a cost can be provided.

  Moreover, the coating film 3 on the surface of the film fixing material 1 not only can prevent a sudden decrease in temperature in the vinyl house H, but also emits far-infrared rays when absorbing sunlight. It can also have a positive effect on agricultural products such as vegetables and fruits cultivated in House H.

  The film fastening material 1 is attached to the vinyl house H by connecting the back side of the bottom wall portion 11 of the film fastening material 1 to the pipe-like aggregate 20 or the side wall portion constituting the roof portion of the vinyl house H. Although it is made by screwing to the plate-like aggregate 21 constituting, a dedicated mounting tool may be used.

  Further, the elastic locking member 15 that is attached to the film fastening material 1 and clamps the film F, and other house construction materials for constructing the vinyl house H, such as pipe-like aggregates 20 and plate-like bones. The material 21, and further, a band binding member (not shown) for binding a so-called house band is applied with the same powder coating as the film fixing material 1.

  Thus, while constructing a framework using various house construction materials that have been subjected to powder coating, the film F is fixed with the film fastening material 1 that is one of the house construction materials, and the framework is constructed with the film F. If the vinyl house H is formed by coating, film burn can be more effectively prevented.

  In addition, some band binding members are used by protruding into the soil around the vinyl house, and it is easy to come out from the soil by powder coating and making the surface rough to increase the coefficient of friction. Can also be prevented.

  As mentioned above, some of the embodiments of the present invention have been described in detail with reference to the drawings. However, these are merely examples, and the present invention is variously modified and improved based on the knowledge of those skilled in the art. It is possible to carry out the invention.
