Description

本発明は、シート定着部材及びシート定着部材の製造方法に関する。   The present invention relates to a sheet fixing member and a method for manufacturing the sheet fixing member.

一般に、シート定着部材は、ビニールハウスの骨組に固定され、このビニールハウスの妻面、屋根面、側面等にシートを展張するために利用されている。   In general, the sheet fixing member is fixed to a frame of a greenhouse, and is used to spread the sheet on the wife surface, roof surface, side surface, and the like of the greenhouse.

このような、シート定着部材の中には、底片と、この底片の両端部から斜め内側に傾斜しながら起立する側片と、底片と側片との間に形成される蟻溝とを備えているものがあり、上記蟻溝内にシートを挿入してから弾性を有する係止部材を挿入することで、シート定着部材にシートを容易に定着させることができる。   Such a sheet fixing member includes a bottom piece, a side piece that stands obliquely inward from both ends of the bottom piece, and a dovetail formed between the bottom piece and the side piece. By inserting an elastic locking member after inserting the sheet into the dovetail groove, the sheet can be easily fixed on the sheet fixing member.

さらに、例えば、特許文献１及び２に開示のシート定着部材では、シート定着部材の表面に紛体塗装を施して微小凹凸を形成することで粗面とし、太陽光が鏡面反射することなく、乱反射するようにしている。このようにすることで、「焼け」と称されるシートの劣化を抑制し、シートの耐候性を向上させることができる。   Furthermore, for example, in the sheet fixing member disclosed in Patent Documents 1 and 2, the surface of the sheet fixing member is coated with powder to form fine irregularities, thereby making the surface rough and reflecting sunlight without specular reflection. I am doing so. By doing in this way, deterioration of the sheet called "burn" can be suppressed and the weather resistance of the sheet can be improved.

特開２００９−１２５００４号公報JP 2009-125004 A 特開２０１２−７０７６２号公報JP 2012-70762 A

ここで、特開２００９−１２５００４号公報や、特開２０１２−７０７６２号公報に開示のシート定着部材においては、シート定着部材の形を形成するための成形工程と、この成形工程で製造されたシート定着部材の表面に紛体塗装を施す塗装工程とが必要となる。   Here, in the sheet fixing member disclosed in Japanese Patent Application Laid-Open No. 2009-125004 and Japanese Patent Application Laid-Open No. 2012-70762, a forming process for forming the shape of the sheet fixing member, and a sheet manufactured in this forming process A coating process for applying powder coating on the surface of the fixing member is required.

また、シート定着部材がアルミ製である場合には、成形工程と塗装工程との間に、成形工程で形成されたシート定着部材の素地表面に陽極酸化皮膜を形成するアルマイト工程が追加され、塗装工程では陽極酸化皮膜上に紛体塗装が施される。   In addition, when the sheet fixing member is made of aluminum, an anodizing process for forming an anodized film on the surface of the sheet fixing member formed in the molding process is added between the molding process and the painting process. In the process, powder coating is applied on the anodized film.

上記した成形工程とアルマイト工程は、工程の性質上、一連の工程として同一工場内で連続的に行うことも可能であり、製造上、アルマイト工程の追加による大きな不具合はないが、塗装工程は、工程の性質上、成形工程やアルマイト工程と同一工場内で連続的に行うことができず、成形工程やアルマイト工程を行う場所から隔離された場所で行う必要がある。   The above-described molding process and anodizing process can be performed continuously in the same factory as a series of processes due to the nature of the process, and there are no major problems due to the addition of the anodizing process in manufacturing, but the painting process is Due to the nature of the process, it cannot be carried out continuously in the same factory as the molding process or alumite process, and must be performed in a place isolated from the place where the molding process or alumite process is performed.

このため、成形工程から塗装工程に移行する際、或いは、アルマイト工程から塗装工程に移行する際の製品の移動、仕掛品の保管等の作業が煩雑となる。また、紛体塗装自体も高価なものであり、これらの理由からシート定着部材の製造コストが嵩んでしまう。   For this reason, when shifting from the molding process to the painting process, or when shifting from the alumite process to the painting process, operations such as product transfer and work-in-process storage become complicated. Also, the powder coating itself is expensive, and for these reasons, the manufacturing cost of the sheet fixing member increases.

そこで、本発明の目的は、上記した不具合を解決するために創案されたものであり、シートの劣化を抑制してシートの耐候性を向上させるとともに、製造コストを安価にすることが可能なシート定着部材及びシート定着部材の製造方法を提供することである。   Therefore, an object of the present invention was created to solve the above-described problems, and is capable of suppressing the deterioration of the sheet to improve the weather resistance of the sheet and reducing the manufacturing cost. It is to provide a method for manufacturing a fixing member and a sheet fixing member.

以下、本発明の一実施形態に係るシート定着部材について、図面を参照しながら説明する。いくつかの図面を通して付された同じ符号は、同じ構成を示す。   Hereinafter, a sheet fixing member according to an embodiment of the present invention will be described with reference to the drawings. The same reference numerals given throughout the drawings indicate the same configuration.

本発明の一実施形態に係るシート定着部材１は、長尺に形成されており、図１に示すように、底片２と、上記底片２の両端から起立する側片３，３と、上記底片２と上記側片３，３との間に形成される蟻溝４とを備え、上記蟻溝４内に係止部材２６を介してシート２５を定着させるものである。そして、本実施形態に係るシート定着部材１の上記底片２と上記側片３，３の素地表面には、溝６が設けられており、この溝６によって凹凸が形成されている。   A sheet fixing member 1 according to an embodiment of the present invention is formed in an elongated shape, and as shown in FIG. 1, a bottom piece 2, side pieces 3 and 3 erected from both ends of the bottom piece 2, and the bottom piece. 2 and a dovetail groove 4 formed between the side pieces 3 and 3, and a sheet 25 is fixed in the dovetail groove 4 via a locking member 26. A groove 6 is provided on the base surface of the bottom piece 2 and the side pieces 3 and 3 of the sheet fixing member 1 according to the present embodiment, and irregularities are formed by the groove 6.

本実施の形態において、シート定着部材１は、ビニールハウスの骨組に固定され、ビニールハウスの妻面、屋根面、側面等にシート２５を展張するために利用されている。   In the present embodiment, the sheet fixing member 1 is fixed to a framework of a greenhouse and is used to spread the sheet 25 on the wife's face, roof surface, side surface, or the like.

以下シート定着部材１の各構成について詳細に説明すると、底片２は、シート定着部材１の図１中下側に長手方向に沿って設けられ、図１中奥行方向に延びている。この底片２は、起伏部５を備えており、この起伏部５は、図１中上側に突出する複数の突部３０と図１中下側に窪む複数の窪部３１とを備えて構成されている。そして、突部３０と窪部３１は底片２の短手方向(図１中左右方向)に交互に連続して設けられている。また、突部３０と窪部３１は、それぞれ底片２の長手方向に連続して設けられている。   Hereinafter, each configuration of the sheet fixing member 1 will be described in detail. The bottom piece 2 is provided along the longitudinal direction on the lower side of the sheet fixing member 1 in FIG. 1 and extends in the depth direction in FIG. The bottom piece 2 includes an undulating portion 5, and the undulating portion 5 includes a plurality of protrusions 30 protruding upward in FIG. 1 and a plurality of recesses 31 recessed downward in FIG. 1. Has been. The protrusions 30 and the recesses 31 are provided alternately and continuously in the short direction of the bottom piece 2 (left and right direction in FIG. 1). Further, the protrusion 30 and the recess 31 are provided continuously in the longitudinal direction of the bottom piece 2.

この起伏部５の上面である蟻溝側面には、シート定着部材１の長手方向に沿う細い直線状の溝６が複数形成されており、これらの溝６は、シート定着部材１の短手方向に所定の間隔をあけて配置されている。このように溝６を設けることで、溝６と溝６以外の部分で本発明に係る凹凸が形成される。また、図２に示すように溝６のふち部分６ａが湾曲しており、シート２５を傷つけないように配慮されている。さらに、本実施の形態において、突部３０と窪部３１とを比較すると、突部３０に形成される溝６の間隔が窪部３１に形成される溝６の間隔より狭くなっている。
A plurality of thin linear grooves 6 along the longitudinal direction of the sheet fixing member 1 are formed on the dovetail side surface which is the upper surface of the undulating portion 5, and these grooves 6 are formed in the short direction of the sheet fixing member 1. Are arranged at predetermined intervals. By providing the groove 6 in this way, the unevenness according to the present invention is formed in a portion other than the groove 6 and the groove 6. Further, as shown in FIG. 2, the edge portion 6 a of the groove 6 is curved so that the sheet 25 is not damaged. Furthermore, in the present embodiment, when the protrusion 30 and the recess 31 are compared, the interval between the grooves 6 formed in the protrusion 30 is narrower than the interval between the grooves 6 formed in the recess 31.

上記底片２の両端から起立する側片３，３は、図１左右対称形状に形成されており、ともに、底片２の長手側となる図１中左端、又は右端から、外側に湾曲しながら立ち上がる湾曲部２２と、この湾曲部２２の反底片側端部から内側に傾斜しながら立ち上がる傾斜部２３と、この傾斜部２３の反湾曲部端部に連設され傾斜部２３の内側に向けて突出する凸部７とを有している。   The side pieces 3 and 3 rising from both ends of the bottom piece 2 are formed in a symmetrical shape in FIG. 1, and both rise from the left or right end in FIG. A curved portion 22, an inclined portion 23 that rises inwardly from an end portion on the opposite bottom side of the curved portion 22, and a projection that protrudes toward the inner side of the inclined portion 23 that is connected to the end portion of the inclined portion 23. And a convex portion 7.

凸部７の上面である反底片側面には、溝６が設けられている。この溝６は、底片２の溝６と同様であり、図３に示すように、シート定着部材１の長手方向に沿う細い直線状とされており、シート定着部材１の短手方向に所定の間隔をあけて、複数平行に配置されている。 A groove 6 is provided on one side surface of the bottom that is the upper surface of the convex portion 7. The groove 6 is the same as the groove 6 of the bottom piece 2 and is formed in a thin straight line along the longitudinal direction of the sheet fixing member 1 as shown in FIG. A plurality are arranged in parallel at intervals.

なお、底片２及び側片３，３の溝６は、シート定着部材１の長手方向に延びる形状に限定されるものでなく、短手方向や縦横無尽に形成されるとしてもよい。また、本発明の凹凸は、直線状の溝６以外によって形成されるとしても良く、例えば、無数の球面状の凹みを設けることで上記凹凸を形成する等、シート定着部材１の素地表面に凹凸を形成するための構成は変更することができる。   The grooves 6 of the bottom piece 2 and the side pieces 3 and 3 are not limited to the shape extending in the longitudinal direction of the sheet fixing member 1, and may be formed in the short side direction or in the vertical and horizontal directions. In addition, the unevenness of the present invention may be formed by other than the linear groove 6. For example, the unevenness is formed on the substrate surface of the sheet fixing member 1 by forming an infinite number of spherical recesses. The structure for forming can be changed.

つづいて、底片２と側片３，３間には、蟻溝４が形成されている。そして、この蟻溝４にシート２５を挿入し、このシート２５を押えるために、係止部材２６をシート２５の上から、蟻溝４に挿入する。この係止部材２６は、蛇行することで弾性を持たせた線材からなり、係止部材２６を、弾性変形させながら蟻溝４に挿入することで、この係止部材２６が反発力でシート２５を側片３，３に押しつけ、シート定着部材１にシート２５を定着させることができる。   Subsequently, a dovetail groove 4 is formed between the bottom piece 2 and the side pieces 3 and 3. And the sheet | seat 25 is inserted in this dovetail groove | channel 4, and the locking member 26 is inserted in the dovetail groove | channel 4 from on the sheet | seat 25 in order to hold down this sheet | seat 25. FIG. The locking member 26 is made of a wire rod that has elasticity by meandering, and the locking member 26 is inserted into the dovetail groove 4 while being elastically deformed. Can be pressed against the side pieces 3 and 3 to fix the sheet 25 to the sheet fixing member 1.

上記したように、側片３，３に湾曲部２２を設けていることで、係止部材２６が湾曲部２２で保持され、係止部材２６が蟻溝４から外れにくくなる。さらに、側片３，３に凸部７を設けていることで、係止部材２６が湾曲部２２から外れることがあっても、係止部材２６が凸部７に接することで、上記係止部材２６が蟻溝４から外れることを防止できる。   As described above, by providing the curved portions 22 on the side pieces 3 and 3, the locking member 26 is held by the curved portion 22, and the locking member 26 is unlikely to be detached from the dovetail groove 4. Further, by providing the convex portions 7 on the side pieces 3, 3, even if the locking member 26 may come off from the curved portion 22, the locking member 26 contacts the convex portion 7, so that the locking The member 26 can be prevented from coming off the dovetail groove 4.

また、上記のように、シート定着部材１にシート２５を定着させた場合、底片２の蟻溝側面と凸部７の反底片側面は、シート２５と接触しやすく、かつ、光を反射させやすい部分である。当該部分では、焼けによるシートの劣化が生じやすい。また、シート２５とシート定着部材１が接触する部分では、水はけが悪くなり、これによってもシート２５の劣化を招くことがある。このため、底片２の蟻溝側面と凸部７の反底片側面に溝６を形成することで光を乱反射させ、焼けによるシート２５の劣化を少ない凹凸でも効率的に抑制し、シート２５の耐候性を向上させるとともに、水はけをよくして、水分に長時間触れることによるシート２５の劣化や、シート定着部材１の錆を抑制することができる。さらには、上記した溝６を形成することで、表面積を増やすことができるので、放熱効果を高めてシート２５の熱による劣化も抑制できる。   Further, as described above, when the sheet 25 is fixed to the sheet fixing member 1, the dovetail side surface of the bottom piece 2 and the anti-bottom piece side surface of the convex portion 7 are easy to contact the sheet 25 and easily reflect light. Part. In this portion, the sheet is likely to be deteriorated due to burning. Further, in the portion where the sheet 25 and the sheet fixing member 1 are in contact with each other, the water drainage is deteriorated, which may cause the sheet 25 to deteriorate. For this reason, the groove 6 is formed in the dovetail side surface of the bottom piece 2 and the anti-bottom piece side surface of the convex portion 7 to diffusely reflect light, and the deterioration of the sheet 25 due to burning can be effectively suppressed even with little unevenness, and the weather resistance of the sheet 25 In addition to improving the performance, drainage is improved, and deterioration of the sheet 25 and rusting of the sheet fixing member 1 due to contact with moisture for a long time can be suppressed. Furthermore, since the surface area can be increased by forming the groove 6 described above, the heat dissipation effect can be enhanced and deterioration of the sheet 25 due to heat can be suppressed.

加えて、底片２が起伏部５を有し、この起伏部５に溝６による凹凸を形成していることにより、底片２が平らな場合と比較してより光を乱反射させることができるとともに、シート２５と底片２の間に貯まった水分の水はけをよくすることができる。   In addition, the bottom piece 2 has the undulating portion 5, and by forming irregularities due to the grooves 6 in the undulating portion 5, the light can be more irregularly reflected as compared with the case where the bottom piece 2 is flat, The drainage of the moisture accumulated between the sheet 25 and the bottom piece 2 can be improved.

なお、シート定着部材１に設ける溝６(凹凸)の場所はこれに限定するものでは無く、例えば、シート定着部材１の全体に溝６を設けてもよく、少なくとも、底片２及び側片３，３の一部に凹凸が形成されていればよい。   The location of the groove 6 (unevenness) provided in the sheet fixing member 1 is not limited to this. For example, the groove 6 may be provided in the entire sheet fixing member 1, and at least the bottom piece 2 and the side pieces 3, It is only necessary that unevenness is formed on a part of 3.

以下、シート定着部材１の製造方法について説明する。   Hereinafter, a method for manufacturing the sheet fixing member 1 will be described.

本実施形態に係るシート定着部材１の製造工程は、成形工程と、この成形工程に続くアルマイト工程からなる。   The manufacturing process of the sheet fixing member 1 according to the present embodiment includes a molding process and an alumite process following the molding process.

成形工程では、アルミ、もしくはアルミ合金からなる母材に圧力をかけて、金型から押出す押出成形により、シート定着部材１の形を形成する。金型には、溝６を形成するための突起が設けられているので、シート定着部材１の底片２と側片３，３を形成すると同時に、シート定着部材１の素地表面に溝６を形成し、凹凸を設けることができる。   In the forming step, the shape of the sheet fixing member 1 is formed by extrusion molding by applying pressure to a base material made of aluminum or an aluminum alloy and extruding from a mold. Since the mold is provided with a protrusion for forming the groove 6, the bottom piece 2 and the side pieces 3 and 3 of the sheet fixing member 1 are formed, and at the same time, the groove 6 is formed on the base surface of the sheet fixing member 1. And unevenness can be provided.

成形工程に続くアルマイト工程では、上記のように形成したシート定着部材１を電解槽に入れることでシート定着部材１の素地表面に陽極酸化皮膜を形成し、シート定着部材１の耐食性や耐摩耗性を向上させる。このように、シート定着部材１の表面に陽極酸化皮膜を形成することで、溝６によって形成させる凹凸表面にも陽極酸化皮膜を形成することができる。   In the alumite process subsequent to the molding process, the sheet fixing member 1 formed as described above is placed in an electrolytic cell to form an anodic oxide film on the surface of the sheet fixing member 1, and the corrosion resistance and wear resistance of the sheet fixing member 1. To improve. As described above, by forming an anodized film on the surface of the sheet fixing member 1, an anodized film can also be formed on the uneven surface formed by the grooves 6.

つまり、本実施形態において、シート定着部材１の素地表面に、光を乱反射させるための凹凸を形成しているので、シート定着部材１をアルミ製またはアルミ合金製にしたとしても成形工程と、アルマイト工程でシート定着部材１を製造することができ、従来のような凹凸を作るための紛体塗装による塗装工程が不要となる。そして、成形工程とアルマイト工程は、工程の性質上同一工場内で連続的に行うことが可能であるので、次工程に移行する際の製品の移動や、仕掛品の保管等の作業が不要となり作業が簡単になる。従って、シート定着部材１の製造コストを安価にすることができる。   That is, in the present embodiment, since the unevenness for irregularly reflecting light is formed on the surface of the base of the sheet fixing member 1, even if the sheet fixing member 1 is made of aluminum or an aluminum alloy, the molding process and the alumite The sheet fixing member 1 can be manufactured in the process, and a conventional painting process by powder coating for making irregularities is not required. Since the molding process and the anodizing process can be performed continuously in the same factory due to the nature of the process, operations such as moving the product when moving to the next process and storing work in progress are not required. Work becomes easy. Therefore, the manufacturing cost of the sheet fixing member 1 can be reduced.

なお、シート定着部材１の製造方法は、上記に記載した方法に限定されるものではなく、シート定着部材１の素地表面に凹凸を形成できることが可能であれば他の方法でもよい。例えば、シート定着部材１が、ステンレス製の時は、アルマイト工程を省略することが可能となる。   The method for manufacturing the sheet fixing member 1 is not limited to the method described above, and other methods may be used as long as it is possible to form irregularities on the base surface of the sheet fixing member 1. For example, when the sheet fixing member 1 is made of stainless steel, the alumite process can be omitted.

また、シート定着部材１を電解槽に入れる時間を変えることにより、シート定着部材１の色をブラウンに変化させることができる。このようにシート定着部材１をブラウンとした場合、工程を増やすことなく、光の反射率を低くすることが可能となり、シート２５の劣化を抑制する効果を高めることができる。なお、シート定着部材１の色は、任意に変更できる。   Further, the color of the sheet fixing member 1 can be changed to brown by changing the time during which the sheet fixing member 1 is placed in the electrolytic cell. Thus, when the sheet fixing member 1 is brown, the light reflectance can be lowered without increasing the number of steps, and the effect of suppressing the deterioration of the sheet 25 can be enhanced. Note that the color of the sheet fixing member 1 can be arbitrarily changed.

また、シート定着部材１の構成は図１〜４に示す形状に限定されるものではなく、例えば、図５〜７に示すように変更されてもよい。   The configuration of the sheet fixing member 1 is not limited to the shape shown in FIGS. 1 to 4, and may be changed as shown in FIGS. 5 to 7, for example.

図５に記載のシート定着部材２０は、底片１０，１１と、この底片１０，１１の両側から起立する側片１２，１３を備えて、長尺に形成される二本のシート定着部材本体８，９と、これらシート定着部材本体８，９の向かいあう側片１２，１３を連結する接続片１６とを備え、底片１０と側片１２，１２との間と、底片１１と側片１３，１３との間に、それぞれシート２５を定着するための蟻溝１８，１９を形成している。   A sheet fixing member 20 shown in FIG. 5 includes two bottom sheet fixing member bodies 8 each having a bottom piece 10, 11 and side pieces 12, 13 rising from both sides of the bottom piece 10, 11. , 9 and connecting pieces 16 for connecting the side pieces 12, 13 facing each other of the sheet fixing member bodies 8, 9, between the bottom piece 10 and the side pieces 12, 12, and between the bottom piece 11 and the side pieces 13, 13.
