Description

本発明は、雨樋の樋集水器及び樋集水器を取り付けた構造物に関する。   The present invention relates to a gutter water collector for rain gutters and a structure to which the gutter water collector is attached.

従来より、軒樋と樋集水器とは、軒樋の下流側端部を樋集水器の挿入部に挿入することによって接続されている。この軒樋が樋集水器の挿入部から抜けるのを防止するために、軒樋の下流側端部に切り込みを入れて多数の切り込み片を形成し、この切り込み片を下方に折曲させたり、樋集水器の差込部の軒樋の下流側端部を挿入した後、軒樋の下流側端部にストッパーを接着剤で取り付けられる方法が行われている。しかしながら、集水器本体の側壁に設けられた軒樋挿入部の長さが短い場合この軒樋挿入部に挿入された軒樋が環境の温度変化によって収縮したとき、この軒樋挿入部から抜けて外れるという問題が生じることがある。 Conventionally, the eaves basket and the water collector are connected by inserting the downstream end of the eave wall into the insertion part of the water collector. In order to prevent the eaves from coming out from the insertion part of the water collector, a cut is made at the downstream end of the eaves to form a large number of cut pieces, and the cut pieces are bent downward. A method of attaching a stopper to the downstream end portion of the eave ridge with an adhesive after inserting the downstream end portion of the eave ridge in the insertion portion of the water collector is performed. However, when the eaves insert portion provided on the side wall of the collector body is short, when the eaves insert inserted into the eaves insert portion contracts due to the temperature change of the environment, it is removed from the eaves insert portion. Problems may occur.

この軒樋の外れを解消する樋集水器として、樋集水器と止水板とからなり、止水板は、集水器本体の側壁もしくは底部から立設され、先端がストッパーの挟持片と折曲片との間に向けられている樋集水器(特許文献1を参照。)が提案されている。

A water collector that eliminates the eaves detachment consists of a water collector and a water stop plate. The water stop plate is erected from the side wall or bottom of the water collector main body, and the tip is a holding piece with a stopper. The water collecting device (refer patent document 1) orient | assigned between a bent piece and a bending piece is proposed.
JP-A-8-246615

しかしながら、この従来の方法では、樋集水器本体の側壁と止水板との間に溝ができ、その溝に雨水が溜まり、さらには雨水が樋集水器の外に流出する場合があった。 However, with this conventional method, a groove is formed between the side wall of the dredger water collector main body and the water stop plate, rainwater collects in the groove, and rainwater may flow out of the dredger water collector. It was.

本発明は従来の欠点を解決し、軒樋の下流側端部を樋集水器の挿入部に挿入することによって接続されている軒樋が、環境の温度変化によって収縮したときに、この軒樋挿入部から抜けて外れるという問題が生じない樋集水器及び樋集水器を取り付けた構造物を提供することである。 The present invention solves the conventional drawbacks, and when the eaves connected by inserting the downstream end of the eaves into the insertion part of the water collector is shrunk due to the temperature change of the environment. It is an object of the present invention to provide a dredger water collector and a structure to which the dredger water collector is attached, in which the problem of coming off from the dredge insertion portion and coming off does not occur.

本発明は、軒樋2を集水器本体1内に突出させ、しかも遮蔽突起11の頂部と軒樋挿入部7とを同一面上にして取り付けられた構造物であって、前記軒樋2の端部には断面コ字形の挟持片9とこの挟持片9から下方に延びた垂下部10とからなるストッパー3を有し、この断面コ字形の挟持片9の間隙に前記軒樋2の端部が挿入されており、前記集水器本体1は、側壁5と、横側壁6と、前記軒樋挿入部7とを有し、この側壁5には、前記ストッパー3と合致する前記遮蔽突起112〜5個が立設されており、その突起部角度12が45°〜90°であることを特徴とする構造物である。 The present invention is a structure in which the eaves bowl 2 is projected into the water collector main body 1 and the top part of the shielding protrusion 11 and the eaves bowl insertion part 7 are mounted on the same plane, At the end, there is a stopper 3 consisting of a clamping piece 9 having a U-shaped cross section and a hanging part 10 extending downward from the clamping piece 9. An end portion is inserted, and the collector main body 1 has a side wall 5, a lateral side wall 6, and an eaves-insertion portion 7. The side wall 5 has the shielding that matches the stopper 3. The structure is characterized in that 2 to 5 protrusions 11 are erected, and the protrusion angle 12 is 45 ° to 90 °.

本発明においては、遮蔽突起11の突起部角度12が45°〜80°であることが好ましい。In the present invention, the projection angle 12 of the shielding projection 11 is preferably 45 ° to 80 °.

本発明の樋集水器は、軒樋が環境の温度変化によって収縮したとき、樋集水器の軒樋挿入部から軒樋が抜けて外れない樋集水器及び樋集水器を取り付けた構造物を提供することができる。 The water collecting apparatus of the present invention is provided with a water collecting apparatus and a water collecting apparatus that cannot be detached when the eaves shrinks due to the temperature change of the environment. A structure can be provided.

本発明は、前記のように環境の温度変化によって軒樋が収縮したとき、集水器本体の側壁から立設された遮蔽突起がストッパーの垂下部と合致することにより、樋集水器の軒樋挿入部から軒樋が抜けて外れないことを見出した。 In the present invention, when the eaves shrinks due to the temperature change of the environment as described above, the shielding protrusions erected from the side wall of the water collector main body match the hanging part of the stopper, I found out that the eaves came out of the eaves insertion part.

本発明における樋集水器の材質は、プラスチック建材として従来公知の樹脂を適宜選択して採用でき、例えば、硬質塩化ビニル樹脂、アクリル樹脂、ポリカーボネート樹脂、AES樹脂(アクリロニトリル・エチレン−プロピレンゴム・スチレン樹脂)等やこれらの混合物を含むものを使用できる。また、軒樋及びストッパーの材質は、樋集水器と同一であっても、異なるものであってもよい。 The material of the water collecting device in the present invention can be selected by appropriately selecting a conventionally known resin as a plastic building material. For example, hard vinyl chloride resin, acrylic resin, polycarbonate resin, AES resin (acrylonitrile / ethylene-propylene rubber / styrene) Resin) and the like and mixtures thereof can be used. Moreover, the eaves bowl and the material of the stopper may be the same as or different from those of the bowl water collector.

本発明の詳細を説明するにあたって、軒樋と樋集水器について主要な構成及び、これらの接続について説明する。図1〜図3において、1は集水器本体、2は軒樋、3はストッパーである。集水器本体1は、底部4と、この底部4の端縁から立設された側壁5と底部4とに接続される横側壁6とよりなる箱型の形状となっている。 In describing the details of the present invention, the main configuration and connection between the eaves and the water collector will be described. 1-3, 1 is a water collector main body, 2 is an eaves bowl, 3 is a stopper. The water collector main body 1 has a box shape including a bottom part 4, a side wall 5 erected from an edge of the bottom part 4, and a lateral side wall 6 connected to the bottom part 4.

集水器本体1の側壁5に軒樋挿入部7が設けられていて、底部4に竪樋接続部8が設けられている。軒樋挿入部7に軒樋2が挿入され、軒樋2の端部は、集水器本体1の内側に突出させられている。 An eaves tub insertion portion 7 is provided on the side wall 5 of the water collector main body 1, and a heel connection portion 8 is provided on the bottom portion 4. The eaves bowl 2 is inserted into the eaves bowl insertion portion 7, and the end of the eaves bowl 2 is projected inside the water collector main body 1.

ストッパー3は、軒樋2の端部を挟持する断面コ字形の挟持片9と、この挟持片9から下方に延びた垂下部10とからなっている。このストッパー3の挟持片9の中に、軒樋挿入部7から挿入された軒樋2の端部が挿入されて取り付けられている。 The stopper 3 includes a sandwiching piece 9 having a U-shaped cross section for sandwiching the end of the eaves 2 and a hanging part 10 extending downward from the sandwiching piece 9. In the holding piece 9 of the stopper 3, the end portion of the eaves rod 2 inserted from the eaves rod insertion portion 7 is inserted and attached.

遮蔽突起11は、集水器本体1の側壁5に、遮蔽突起11の方向が軒樋2の端部側になるように立設されている。この遮蔽突起11を側壁5に立設したのは、底部4から突起を出すと、軒樋2の収縮により、遮蔽突起11に当たったときに遮蔽突起11を変形させる可能性があり、更には、竪樋への排水に障害をきたすためである。側壁5から直接突出させたのは、側壁5と遮蔽突起11の間に溝を設けないためである。これにより、遮蔽突起11の近傍に雨水が溜まらない。 The shielding protrusion 11 is erected on the side wall 5 of the water collector main body 1 so that the direction of the shielding protrusion 11 is on the end side of the eaves bowl 2. The reason why the shielding projection 11 is erected on the side wall 5 is that when the projection is protruded from the bottom portion 4, the shielding projection 11 may be deformed when it hits the shielding projection 11 due to contraction of the eaves 2. This is to cause an obstacle to the drainage of water. The reason for projecting directly from the side wall 5 is that no groove is provided between the side wall 5 and the shielding projection 11. Thereby, rainwater does not collect in the vicinity of the shielding protrusion 11.

また遮蔽突起11は、集水器本体1の側壁5に、その側壁5の片側毎に、好ましくは2〜5箇所、さらに好ましくは2〜3箇所立設されている。2箇所未満では、ストッパー3の取り付け位置に遮蔽突起11の立設された位置が対応できなくなる恐れがある。一方で、5箇所を超えると集水器本体1の金型構造が複雑になり、側壁5の部分に外観上に悪さを与えるヒケが発生する恐れがある。 Moreover, the shielding protrusion 11 is preferably erected on the side wall 5 of the collector main body 1 for each side of the side wall 5, preferably 2 to 5 places, more preferably 2 to 3 places. If there are less than two places, the position where the shielding projection 11 is erected may not correspond to the position where the stopper 3 is attached. On the other hand, when it exceeds five places, the mold structure of the collector main body 1 becomes complicated, and there is a possibility that sink marks that give bad appearance on the side wall 5 may occur.

遮蔽突起11の頂部は軒樋挿入部7と同一面上であることが望ましい。突起部角度12は、前記頂部を基準として45°〜90°の範囲である。突起部角度12が45°より小さいと、あまりにも鋭角になりすぎて遮蔽突起11の先端に外観上に悪さを与えるヒケが発生する恐れがある。一方で、突起部角度12が90°より大きいと、軒樋2が環境の温度変化によって収縮したときに軒樋2に働く力の一部が、ストッパー3を上方向に押し上げる力になり、係止効果が小さくなり軒樋挿入部7から軒樋2が抜けて外れやすくなる。 The top of the shielding protrusion 11 is preferably on the same plane as the eaves insertion portion 7. The protrusion angle 12 is in the range of 45 ° to 90 ° with the top as a reference. If the projection angle 12 is smaller than 45 °, the sharpness may be too sharp and the tip of the shielding projection 11 may have a bad appearance. On the other hand, if the projection angle 12 is larger than 90 °, a part of the force acting on the eaves 2 when the eaves 2 contracts due to the temperature change of the environment becomes the force that pushes the stopper 3 upward. The stopping effect is reduced, and the eaves 2 is easily removed from the eaves insertion part 7.

この樋集水器を取り付けた構造物の施工手順を説明する。軒樋2の端部にストッパー3を雨樋用接着剤にて固定する。次に、集水器本体1の軒樋挿入部7に軒樋2を取り付ける。集水器本体1のもう一方の軒樋挿入部7に別の軒樋2の端部を挿入し、前記と同様にしてこの軒樋2の端部にストッパー3を接着固定して取り付ける。このようにして樋集水器が取り付けられた軒樋2は、いずれも屋根の先端部直下に固定されていて、最後に集水器本体1の底部4に設けられた竪樋接続部8に竪樋を挿入し施工された樋集水器は、軒樋2に落下した屋根の雨水を集水器本体1に集め、竪樋を経て排出するために使用される。 The construction procedure of the structure to which this dredger is attached will be described. The stopper 3 is fixed to the end of the eaves basket 2 with an adhesive for rain gutters. Next, the eaves bowl 2 is attached to the eaves bowl insertion portion 7 of the water collector main body 1. The end of another eaves ridge 2 is inserted into the other eaves ridge insertion portion 7 of the water collector main body 1, and the stopper 3 is adhered and fixed to the end of the eaves ridge 2 in the same manner as described above. The eaves ridges 2 attached with the basin water collector in this way are all fixed immediately below the front end of the roof, and finally are connected to the basin connection 8 provided on the bottom 4 of the water collector body 1. The dredger water collector constructed by inserting a gutter is used to collect rainwater on the roof that has fallen on the eaves gutter 2 in the water collector body 1 and to discharge it through the gutter.

また、ストッパー3には、軒樋2の端部を挟持する断面コ字形の挟持片9と、この挟持片9から下方に延びた垂下部10とからなっているので、この垂下部10によって雨水が水切りされ、軒樋2から流れてきた雨水はこの垂下部10を伝わって集水器本体1の底部4に落下し、軒樋2の端部裏面を伝わって軒樋挿入部7から漏水することを防止している。 Further, the stopper 3 includes a holding piece 9 having a U-shaped cross section for holding the end of the eaves 2 and a hanging part 10 extending downward from the holding piece 9. The rainwater that has been drained from the eaves bowl 2 travels along the drooping portion 10 and falls to the bottom 4 of the collector body 1, and travels through the back of the end of the eaves bowl 2 to leak from the eaves bowl insertion section 7. To prevent that.

そして、軒樋2が環境の温度変化によって収縮して、軒樋2の端部が軒樋挿入部7の方向に移動すると、この軒樋2の端部が挿入されたストッパー3も軒樋2と一緒に移動する。すると、ストッパー3の垂下部10が集水器本体1の側壁5から立設された遮蔽突起11に当たり、軒樋2の移動が阻止されるので、軒樋2が樋集水器の軒樋挿入部7から抜け外れない。 When the eaves 2 contracts due to the temperature change of the environment and the end of the eaves 2 moves in the direction of the eaves insertion portion 7, the stopper 3 into which the end of the eaves 2 is inserted is also the eaves 2. Move with. Then, the drooping portion 10 of the stopper 3 hits the shielding protrusion 11 erected from the side wall 5 of the water collector main body 1, and the movement of the eaves rod 2 is prevented. It cannot be removed from part 7.

以下、本発明に係る樋集水器の実施例について、図1〜図3及び表1を参照にしながら詳細に説明する。 Hereinafter, the Example of the dredging water collector which concerns on this invention is described in detail, referring FIGS. 1-3 and Table 1. FIG.

Figure 0004407905
Figure 0004407905

表1において、「軒樋の抜け外れ」とは、軒樋(長さ3.6m)の端部にストッパー3を接着剤にて固定し、集水器本体1の軒樋挿入部7に軒樋2を取り付ける。さらに、集水器本体1のもう一方の軒樋挿入部7に別の軒樋2の端部を挿入し、前記と同様にしてこの軒樋2の端部にストッパー3を接着固定して取り付けたこれらのものを試験体とする。この試験体を評価試験室に、軒樋2の収縮を阻害しないよう軒樋〜樋集水器〜軒樋が直線上になるよう備え付ける。軒樋2の収縮を促進させるため、評価試験室の室温を20℃→50℃→−10℃→20℃と室温を変化させ、各温度に24時間ずつ試験体を放置して、樋集水器から軒樋の抜け外れの度合いを目視で評価した。抜け外れがないものを良好(○)とし、抜け外れのあるものを不適(×)とした。抜け外れの基準は、ストッパー3が付いた軒樋2の端部が、軒樋挿入部7の端で浮いた状態を、抜け外れのあるものとした。これは、実際の建物の軒樋は長尺に取り付けられているため、前記の軒樋挿入部7の端で浮いた状態になると、樋集水器から軒樋が抜け外れる恐れがあるためである。 In Table 1, “escape from the eaves” means that the stopper 3 is fixed to the end of the eaves (length: 3.6 m) with an adhesive, and the eaves are inserted into the eaves insertion part 7 of the collector body 1. Install 樋 2. Further, insert the end of another eave ridge 2 into the other eave ridge insertion portion 7 of the water collector main body 1, and attach and fix the stopper 3 to the end of the eave ridge 2 in the same manner as described above. These are the test specimens. The test specimen is installed in the evaluation test room so that the eaves 樋 to the water collector to the eaves lie in a straight line so as not to inhibit the shrinkage of the eaves 2. In order to promote the shrinkage of the eaves 2, the room temperature of the evaluation test room was changed from 20 ° C. → 50 ° C. → −10 ° C. → 20 ° C., and the test specimens were left at each temperature for 24 hours. The degree of detachment of the eaves from the vessel was visually evaluated. Those that did not come off were judged as good (◯), and those that came off were judged unsuitable (x). As a standard for detachment, the state in which the end of the eaves rod 2 with the stopper 3 floats at the end of the eaves ridge insertion portion 7 is assumed to be detached. This is because the eaves of an actual building is attached to a long length, and if the eaves are floated at the end of the eaves insertion part 7, the eaves may come off from the water collector. is there.

(実施例1)本実施例の樋集水器及びストッパーは、硬質塩化ビニル樹脂製で射出成型機を用いて賦形した。これに対応する軒樋は、底幅が90mmである角形軒樋(電気化学工業株式会社製 CR105)を使った。遮蔽突起11の突起部角度12は80°である。また、遮蔽突起11の個数は、集水器本体1の側壁5の両側に、30mmの間隔で2箇所ずつ配設した。ストッパー3は、軒樋との接着代が45mmのストッパー(電気化学工業株式会社製 軒樋ストッパー)を、軒樋端部に1個ずつ使った。 (Example 1) The water collector and stopper of this example were made of hard vinyl chloride resin and shaped using an injection molding machine. The eaves corresponding to this was a square eaves (CR105 manufactured by Denki Kagaku Kogyo Co., Ltd.) having a bottom width of 90 mm. The projection angle 12 of the shielding projection 11 is 80 °. In addition, the number of the shielding protrusions 11 was arranged at two locations at intervals of 30 mm on both sides of the side wall 5 of the water collector main body 1. As the stopper 3, a stopper (electrochemical industry Co., Ltd. Eaves stopper) having a bonding allowance with the eaves was used one by one at the end of the eaves.

(実施例2及び比較例1,2)比較例2は、遮蔽突起11がないもの。実施例2及び比較例1は、突起部角度12を表1に示した値とした以外は、実施例1と同様にして樋集水器を得た。 (Example 2 and Comparative Examples 1 and 2) Comparative Example 2 has no shielding protrusion 11. In Example 2 and Comparative Example 1, a water catcher was obtained in the same manner as in Example 1 except that the protrusion angle 12 was set to the value shown in Table 1.

各実施例及び比較例の評価結果を、表1に纏めて示した。表1から、ストッパー3と合致する遮蔽突起11の突起部角度12が45°〜90°の範囲で形成されていることが好ましい。本実施例の樋集水器を取り付けた構造物は、軒樋2の抜け防止機能がある。 The evaluation results of each example and comparative example are summarized in Table 1. From Table 1, it is preferable that the projection angle 12 of the shielding projection 11 that coincides with the stopper 3 is formed in the range of 45 ° to 90 °. The structure attached with the water collector of this embodiment has a function to prevent the eaves 2 from coming off.
