Description
本発明は、連棟温室の融雪屋根構造に係り、特に、積雪地帯に用いるのに好適な、屋根を滑り落ちる雪塊の形状や量を均一化して、融雪性能を安定化させ、融雪エネルギーの削減を図ることが可能な連棟温室の融雪屋根構造に関する。 The present invention relates to a snowmelt roof structure of a multi-storey greenhouse, and in particular, suitable for use in a snowy area, uniformizing the shape and amount of a snow mass sliding down the roof, stabilizing the snowmelt performance, and reducing snowmelt energy. This is related to the snowmelt roof structure of a multi-storey greenhouse that can be used.
従来より、温室として種々のものが提案されているが、中でも、建設費の低減を図ることができること、及び、温室を構築する施設面積を効率的に利用できることなどから、連棟型の温室（連棟温室と称する）が良く利用されている。 Conventionally, various greenhouses have been proposed, but among them, the construction cost can be reduced and the facility area for constructing the greenhouse can be used efficiently. A multi-storey greenhouse) is often used.
この連棟温室は、図１に例示する如く、例えば切妻式の屋根に組立てられる単位温室１を棟方向に平行に並設させ、且つ、隣接する側壁の支柱２を隣接する単位温室１同士で共有させ、更に隣接する単位温室１の左右に傾斜する屋根３の軒端を前記支柱２の上端部に支持された谷樋４で連結した形に構築されたものである。 As shown in FIG. 1, for example, this continuous greenhouse has unit greenhouses 1 assembled on a gable roof, for example, arranged in parallel in the building direction, and adjacent side wall columns 2 between adjacent unit greenhouses 1. Further, the eaves end of the roof 3 inclined to the left and right of the adjacent unit greenhouse 1 is connected with a valley trough 4 supported by the upper end of the support column 2.
ところで、雪の多い積雪地帯では、温室の屋根に雪が積もり屋根の採光面積が激減し、温室の特徴である採光性を充分に生かせない。そこで、屋根を融雪する方法として、
（１）例えば特許文献１に記載されるような散水方法、
（２）例えば特許文献２に記載されるような屋根面全体の加熱方法、
（３）例えば特許文献３に記載されるような連棟樋部へ温水管などの加熱源を配置する方法、
などが提案されている。
By the way, in a snowy area with a lot of snow, snow is piled up on the roof of the greenhouse, and the daylighting area of the roof is drastically reduced, so that the daylighting characteristic of the greenhouse cannot be fully utilized. So, as a way to melt snow on the roof,
(1) A watering method as described in Patent Document 1, for example,
(2) A method for heating the entire roof surface as described in Patent Document 2, for example
(3) For example, a method of disposing a heating source such as a hot water pipe in a continuous ridge as described in Patent Document 3,
Etc. have been proposed.
しかしながら、（１）の散水は、北海道のような降雪時の気温が氷点下となる場合には凍結して使用できない。 However, the watering of (1) cannot be frozen and used when the temperature during snowfall is below freezing, as in Hokkaido.
又、（２）のように屋根面全体を加熱する方法は、エネルギー消費が大きい。 Further, the method of heating the entire roof surface as in (2) consumes a large amount of energy.
又、（３）のように樋部へ加熱源を配置する方法は、屋根を滑り落ちる雪の量により融雪性能が変化し、適度な大きさで雪が屋根を滑り落ちてくれないと、桶部に雪が流れ込まず、十分に融雪性能を発揮できない場合がある等の問題点を有していた。 In addition, as shown in (3), the method of disposing the heating source on the buttock changes the snow melting performance depending on the amount of snow sliding down the roof, and if the snow does not slide down the roof at an appropriate size, There was a problem that snow could not flow in and snow melting performance could not be fully exhibited.
本発明は前記従来の問題点を解決するべくなされたもので、屋根を滑り落ちる雪の量を安定化させることによって、融雪性能を効果的に発揮可能な温室屋根を提供することを課題とする。 The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a greenhouse roof capable of effectively exhibiting snow melting performance by stabilizing the amount of snow sliding down the roof.
本発明は、天窓部分においては、雪塊が過大とならず、適切な形状や量で屋根を滑り落ちることに着目してなされたものである。 In the skylight portion, the present invention has been made by paying attention to the fact that snow blocks do not become excessive, and slide down the roof with an appropriate shape and amount.
まず、図２を参照して、雪が屋根を滑るメカニズムについて説明する。 First, the mechanism by which snow slides on the roof will be described with reference to FIG.
図２（Ａ）に示すように、温室１０の屋根１２に降る雪１４は、屋根内側面からの入熱で一部溶けながら積もっていく。降り積もった雪１４は、図２の（Ｂ）に示すように、一定の厚みに達すると重力で屋根面を滑り落ちるが、その時、雪１４の付着力が大きいと滑り落ちるまでの摩擦が大きくなったり、滑り落ちる雪塊の形状が不揃いになる。 As shown in FIG. 2 (A), the snow 14 falling on the roof 12 of the greenhouse 10 accumulates while being partially melted by heat input from the inner surface of the roof. As shown in FIG. 2 (B), the accumulated snow 14 slides down the roof surface due to gravity when it reaches a certain thickness. At that time, if the snow 14 has a large adhesive force, friction until it slides down increases. The shape of the falling snow lump becomes uneven.
特に、図３（天窓の構造と垂木形状を示す断面図）、図４（屋根端部の構造を示す断面図）及び図５（天窓の厚みを示す断面図）に示すような天窓３２の部分では、天窓３２の大きさで雪が綺麗に分断されて適切な雪が滑り落ちていくが、一方、天窓３２以外の部分では、滑り落ちる雪の形状が不揃いになる。ここで天窓３２の部分で雪の大きさが制限されるのは、天窓３２の枠の厚みｔ1が例えば３５ｍｍと厚く、その伝熱性能が良いため、ここで雪が分断されるものと考えられる。 In particular, the part of the skylight 32 as shown in FIG. 3 (cross-sectional view showing the structure of the skylight and the rafter shape), FIG. 4 (cross-sectional view showing the structure of the roof edge) and FIG. 5 (cross-sectional view showing the thickness of the skylight). Then, the snow is neatly divided by the size of the skylight 32 and appropriate snow slides down. On the other hand, in the portions other than the skylight 32, the shape of the snow falling down becomes uneven. Here the part of the snow size of the skylight 32 is limited, as thick as the thickness t 1 is for example 35mm frame skylight 32, therefore the heat transfer performance is good, it is considered that the snow is cut here .
図において、２４は屋根頂上部を支える構造部材、２６は屋根頂上部以外を支える構造部材、２８は棟木、３０は垂木、３４は、垂木３０や天窓３２に貼られた屋根フィルムである。 In the figure, 24 is a structural member that supports the roof top, 26 is a structural member that supports other than the roof top, 28 is a purlin, 30 is a rafter, and 34 is a roof film affixed to the rafter 30 or skylight 32.
従来の屋根においては、屋根フィルム３４が図６に示すような、例えば高さｔ2が６．７ｍｍ程度のアルミニウム製のフィルム留め金具４０によって、例えば受け金具４２、Ｌ字状留め金具４４及びステー４６を介して垂木３０に留められている。図において、５０、５２、５４はボルトである。 In the conventional roof, as shown in FIG. 6, the roof film 34 is made of, for example, an aluminum film clasp 40 having a height t 2 of about 6.7 mm, for example, a receiving clasp 42, an L-shaped clasp 44, and a stay. It is fastened to the rafter 30 via 46. In the figure, 50, 52 and 54 are bolts.
これに対して天窓３２の部分では、図３、図５に示したように、その枠が厚みｔ1＝３５ｍｍ程度と厚いため、高い伝熱性能を有しており、積もった雪の層に滑り落ちる方向と平行に雪粒の結合力が弱い部分が融雪により形成され、天窓枠間の雪の層が滑らかに滑り落ちていくと考えられる。 On the other hand, in the skylight 32 portion, as shown in FIGS. 3 and 5, since the frame is as thick as about t 1 = 35 mm, it has a high heat transfer performance, and the snow layer is piled up. It is thought that a part where the bonding force of snow particles is weak parallel to the sliding-down direction is formed by melting snow, and the snow layer between the skylight frames slides down smoothly.
本発明は、このような点に着目してなされたもので、屋根フィルムがフィルム留め金具により留められている連棟温室の融雪屋根構造において、屋根最上部と、屋根妻面端部と、滑り方向と平行な屋根垂木部分に伝熱性能が良い伝熱部材を配設したことを特徴とする連棟温室の融雪屋根構造により、前記課題を解決するものである。 The present invention has been made paying attention to such points, and in a snowmelt roof structure of a multi-layer greenhouse in which a roof film is fastened by a film fastener, a roof top part, a roof end face part, a slip The above-mentioned problem is solved by a snowmelt roof structure of a multi-storey greenhouse characterized in that a heat transfer member having good heat transfer performance is disposed on a roof rafter portion parallel to the direction.
ここで、前記伝熱部材を、フィルム留め金具を厚肉としたものとすることができる。 Here, the heat transfer member may be a thick film fastener.
又、前記伝熱部材を、フィルム留め金具に発熱体を内蔵させたものとすることができる。 Further, the heat transfer member may be a film clasp in which a heating element is incorporated.
本発明によれば、伝熱性能が良い伝熱部材により、屋根を滑り落ちる雪塊の形状や量を均一化して、融雪性能を安定させ、融雪エネルギーの削減を図ることができる。 ADVANTAGE OF THE INVENTION According to this invention, the shape and quantity of the snow lump which slides down a roof can be equalize | homogenized by a heat transfer member with favorable heat transfer performance, snow melting performance can be stabilized, and reduction of snow melting energy can be aimed at.
以下、図面を参照して、本発明の実施の形態について詳細に説明する。なお、本発明は以下の実施形態及び実施例に記載した内容により限定されるものではない。又、以下に記載した実施形態及び実施例における構成要件には、当業者が容易に想定できるもの、実質的に同一のもの、いわゆる均等の範囲のものが含まれる。更に、以下に記載した実施形態及び実施例で開示した構成要素は適宜組み合わせてもよいし、適宜選択して用いてもよい。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
