Description

本発明は、カーポートやテラスなどの簡易屋根その他の建物や構造物の屋根に使用される合成樹脂製の屋根材とこれを用いて構成される簡易屋根に関する。   The present invention relates to a synthetic resin roof material used for a simple roof such as a carport or a terrace or the roof of another building or structure, and a simple roof configured using the same.

図13はカーポートとして用いられる簡易屋根の一例を示している。この簡易屋根は、基礎面に立設させた支柱10、10の上部に縦横格子状に配した支持材5を設置するとともに、所定の間隔を開けて並設された各支持材5、5間に屋根材1を架設し、屋根材1の端部を支持材5とその上部に設けた押え材6とで挟持固定して構成されている(後述の図14及び図15参照)。
このような簡易屋根の屋根材1としては、耐候性を有する透明な合成樹脂板、例えばポリ塩化ビニルやアクリル、ポリカーボネートなどで成形された波板、平板、折板などが使用されているが、簡易屋根の設置場所や取り付ける屋根材1の大きさなどによっては、台風などの強風発生時の風圧で屋根材1が煽られ、屋根材1が撓んだり反ったりして、屋根材1の端部を支持材5と押え材6の間から引き抜く方向の力が働き、場合によっては屋根材1が支持材5から外れたり破損して飛散したりする虞があった。
FIG. 13 shows an example of a simple roof used as a carport. This simple roof is provided with support materials 5 arranged in a vertical and horizontal grid pattern on the upper sides of the support columns 10 and 10 erected on the foundation surface, and between the support materials 5 and 5 arranged in parallel at predetermined intervals. The roofing material 1 is erected, and the end of the roofing material 1 is sandwiched and fixed between the supporting material 5 and the presser material 6 provided on the upper part (see FIGS. 14 and 15 described later).
As the roof material 1 of such a simple roof, a transparent synthetic resin plate having weather resistance, for example, a corrugated plate, a flat plate, a folded plate, etc. formed of polyvinyl chloride, acrylic, polycarbonate or the like is used. Depending on the installation location of the simple roof and the size of the roofing material 1 to be installed, the roofing material 1 is beaten by the wind pressure when a strong wind such as a typhoon is generated, and the roofing material 1 is bent or warped. A force in the direction of pulling out the portion from between the support material 5 and the presser material 6 acts, and in some cases, the roof material 1 may be detached from the support material 5 or may be broken and scattered.

かかる問題を解決するための屋根材1の取り付け構造として、図14に示されるように、屋根材1の端部に突部11を形成し、前記屋根材1を引き抜く方向の力が作用したときに、支持材5と押え材6に突部11が係合することで屋根材1が支持材5から外れることを防止する構造や、図15に示されるように、屋根材1の端部の上面又は下面に適宜な幅の凹部12を形成し、この凹部12内に支持材5と押え材6とで押圧するパッキン71を圧入させることによって屋根材1を外れ難くした構造が知られている(例えば特許文献1、2参照)。   As shown in FIG. 14, as a structure for attaching the roofing material 1 for solving such a problem, when a protrusion 11 is formed at the end of the roofing material 1 and a force in the direction of pulling out the roofing material 1 is applied. In addition, the protrusion 11 engages with the support member 5 and the presser member 6 to prevent the roof member 1 from being detached from the support member 5, and as shown in FIG. A structure is known in which a recess 12 having an appropriate width is formed on the upper surface or the lower surface, and a packing 71 pressed by the support material 5 and the presser material 6 is press-fitted into the recess 12 to make it difficult to remove the roof material 1. (For example, refer to Patent Documents 1 and 2).

特開2007−85035号公報JP 2007-85035 A 特開2007−204955号公報JP 2007-204955 A

前記図示した従来の屋根材1の取り付け構造のうち、前者のものは、突部11を設けて屋根材1の端部のみの肉厚を大きくしたのでは屋根材1の成形コストが嵩んで実用的でなく、また、強風時に屋根材1を引き抜く方向に大きな力が作用した際に突部11が支持材5と押え材6にぶつかって屋根材1の端部が破損し易いという問題がある。
後者のものは、屋根材1の端部の凹部12内にパッキン71が圧入している状態で屋根材1を取り付け位置に安定的に保持できるものの、強風を受けて屋根材1が撓んだり反ったりしたときに屋根材1の位置がずれ、その際にパッキン71が凹部12内から少しでも外れると屋根材1を保持する力が弱まり、凹部12がパッキン71を乗り越えて屋根材1の端部が支持材5と押え材6の間から外れてしまい易いという問題がある。このものは、凹部12とパッキン71の幅を揃え、凹部12内にパッキン71がぴったりと隙間なく圧入されていなければ、却って屋根材1の端部が抜け易くなってしまう。
Of the mounting structure of the conventional roofing material 1 shown in the figure, the former one is practical because the protrusion 11 is provided and the thickness of only the end of the roofing material 1 is increased, which increases the molding cost of the roofing material 1. In addition, when a large force is applied in the direction of pulling out the roofing material 1 in a strong wind, there is a problem that the end of the roofing material 1 is easily damaged by the protrusion 11 hitting the support material 5 and the pressing material 6. .
Although the latter can stably hold the roofing material 1 in the mounting position in a state where the packing 71 is press-fitted in the recess 12 at the end of the roofing material 1, the roofing material 1 may be bent due to strong winds. The position of the roofing material 1 is shifted when it is warped, and when the packing 71 is slightly removed from the inside of the recess 12, the force for holding the roofing material 1 is weakened, and the recess 12 gets over the packing 71 and the end of the roofing material 1. There exists a problem that a part tends to remove | deviate from between the support material 5 and the pressing material 6. FIG. In this case, the widths of the recess 12 and the packing 71 are aligned, and the end of the roofing material 1 is easily removed unless the packing 71 is press-fitted in the recess 12 without any gaps.

本発明は従来技術の有するこのような問題点に鑑み、簡易屋根などに用いられる合成樹脂製の屋根材において、強風を受けて屋根材が撓んだり反ったりしても、端部が支持材から外れることなく、当初の取り付け位置である支持材間に安定的に固定し保持しておくことができ、また、従来の屋根材と同様の簡易な作業で取り付けることができるようにすることを課題とする。   In view of such problems of the prior art, the present invention is a synthetic resin roof material used for a simple roof or the like. Even if the roof material is bent or warped due to strong wind, the end portion is a support material. It can be stably fixed and held between the support members that are the original attachment positions without detaching from the original, and can be attached by the same simple work as conventional roofing materials. Let it be an issue.

前記課題を解決するため本発明は、所定間隔を開けて並設した支持材に架設される屋根材であって支持材と支持材の上部に設けた押え材の間に弾性体を挟んで差し入れた端部が前記両部材で挟持固定されて取り付けられる合成樹脂製の屋根材において、
前記屋根材の上面全体又は下面全体に、
前記弾性体との間に生じる摩擦抵抗を増加させるための処理であって、前記屋根材の両端に沿って連続して延び、且つ前記支持材の長手方向と直交する方向に凹凸が連続した凹凸部からなる摩擦抵抗増加処理が施されてなることを特徴とする。
In order to solve the above-mentioned problems, the present invention provides a roofing material to be laid on a support material arranged in parallel at a predetermined interval, and an elastic body is inserted between the support material and a presser material provided above the support material. In the roofing material made of synthetic resin that is attached with the end portion sandwiched and fixed by the both members,
On the entire top or bottom surface of the roofing material ,
A process for increasing the frictional resistance generated between the elastic body and the unevenness that continuously extends along both ends of the roofing material and has unevenness in a direction perpendicular to the longitudinal direction of the support material. It is characterized by being subjected to a frictional resistance increasing process consisting of parts .

本発明の屋根材は、並設された支持材間に架け渡し、その両端部の上下両面を、それぞれ弾性体を介して支持材と押え材とで挟み持ち、端部表面に弾性体が圧接するように両部材を挟持位置に固定することにより取り付けられる。
弾性体が接する屋根材の端部には、弾性体との間に生じる摩擦抵抗を増加させるための摩擦抵抗増加処理が施されているので、強風を受けて屋根材の端部を支持材と押え材との挟持位置から引き抜く方向の力が働くと、屋根材の端部が変位せんとする方向とは逆向きに摩擦力が働き、この摩擦力が抵抗となって端部を取り付け位置に押し止め、屋根材を当初の取り付け位置に固定し保持するように機能して、屋根材の撓みによる引き抜けの可能性を減少させ、屋根材の支持材からの脱落や飛散を防止する効果を向上させることができる。
また、従来の屋根材の取り付け構造を採用する屋根に取り付けることができるので、構造の煩雑化及びコストの増大を招くことなく、従来の合成樹脂製の屋根材と同様の簡単な取り付け作業で屋根を施工することができ、また、既設の屋根材に代えて取り付けることも可能である。
The roofing material of the present invention is bridged between support members arranged side by side, and the upper and lower surfaces of both ends thereof are sandwiched between the support material and the presser material via elastic bodies, and the elastic body is pressed against the end surface. It is attached by fixing both members in the clamping position.
The end of the roofing material in contact with the elastic body is subjected to a frictional resistance increasing process for increasing the frictional resistance generated between the elastic body and the end of the roofing material as a support material in response to strong winds. When a force in the direction of pulling out from the holding position with the presser material is applied, a frictional force acts in the direction opposite to the direction in which the end of the roofing material is displaced, and this frictional force acts as a resistance to move the end to the mounting position. It functions to hold down and hold the roofing material in the original mounting position, reducing the possibility of pulling out due to bending of the roofing material, and preventing the roofing material from falling off and scattering. Can be improved.
In addition, since it can be attached to a roof that adopts a conventional roofing material mounting structure, the roof can be installed by the same simple mounting work as a conventional synthetic resin roofing material without incurring the complexity of the structure and increasing the cost. It is also possible to install the roofing material instead of the existing roofing material.

屋根材の表面に施す摩擦抵抗増加処理は、図1(A)に示されるように、少なくとも弾性体を挟んで支持材と押え材とで挟持されて、弾性体が接合する屋根材1の端部の上面又は下面に設けられ、より好ましく上面又は下面の端部縁部に亘って設けることができる。同図(B)に示されるように、摩擦抵抗増加処理部3Aを屋根材1の上面全体又は下面全体に設けてもよい。同図(C)に示されるように、屋根材1の全周辺に摩擦抵抗処理部3Aを設けてもよい。なお、屋根材1の形状は、正方形や矩形、その他の多角形など、その取り付け態様に応じて適宜に設定される。   As shown in FIG. 1 (A), the frictional resistance increasing process applied to the surface of the roof material is sandwiched between the support material and the presser material with at least the elastic body interposed therebetween, and the end of the roof material 1 to which the elastic body joins. It is provided on the upper surface or the lower surface of the portion, and more preferably can be provided over the edge portion of the upper surface or the lower surface. As shown in FIG. 5B, the frictional resistance increasing processing portion 3A may be provided on the entire upper surface or the entire lower surface of the roofing material 1. As shown in FIG. 3C, a frictional resistance processing portion 3A may be provided around the entire periphery of the roofing material 1. In addition, the shape of the roofing material 1 is suitably set according to the attachment aspect, such as a square, a rectangle, and another polygon.

摩擦抵抗増加処理は、屋根材の端部の変位に対し、屋根材の表面に圧接する弾性体と協働して大きな摩擦力が働くように屋根材の表面を加工する処理であり、例えば図2に示されるように、屋根材1の表面に凹凸部3を形成することが挙げられる。凹凸部3を形成することで弾性体との接触面積が大きくなって、大きな摩擦抵抗が得られる。この凹凸部3は、支持材の長手方向と平行に屋根材1の両端に沿って連続して延び、且つ前記支持材の長手方向と直交する方向に凹凸が連続するように形成することが好ましい。
また、弾性体に対する摩擦抵抗が大きなゴム製や合成樹脂製その他の素材からなるシートやフィルムを屋根材1の表面に剥離不能に固着してもよい。屋根材1の表面全体に、凹凸部3を設けたり摩擦抵抗増加用のシートやフィルムを貼ったりする摩擦抵抗増加処理を施せば、屋根材1の剛性が増して撓みや反りが生じ難くなって好ましい。
さらに、屋根材1は、摩擦抵抗増加処理に加えて、その表面に紫外線吸収層を設けて構成することができる。
The frictional resistance increasing process is a process of processing the surface of the roofing material so that a large frictional force works in cooperation with the elastic body pressed against the surface of the roofing material with respect to the displacement of the end of the roofing material. As shown in FIG. 2, formation of the concavo-convex portion 3 on the surface of the roofing material 1 can be mentioned. By forming the concavo-convex portion 3, the contact area with the elastic body is increased, and a large frictional resistance is obtained. The concavo-convex portion 3 is preferably formed so as to extend continuously along both ends of the roofing material 1 in parallel with the longitudinal direction of the support material and to be continuous in a direction orthogonal to the longitudinal direction of the support material. .
Further, a sheet or film made of rubber, synthetic resin, or other material having a high frictional resistance against the elastic body may be fixed to the surface of the roof material 1 so as not to be peeled off. If the surface of the roofing material 1 is subjected to a frictional resistance increasing process such as providing an uneven portion 3 or attaching a sheet or film for increasing the frictional resistance, the rigidity of the roofing material 1 is increased and bending or warping is less likely to occur. preferable.
Furthermore, the roofing material 1 can be configured by providing an ultraviolet absorbing layer on the surface thereof in addition to the frictional resistance increasing process.

また、本発明の簡易屋根は、図13に示した従来の簡易屋根と同様に、支柱と、支柱の上部に所定間隔を開けて並設させた支持材と、支持材の上方に当該支持材との間隔を調整可能に設けた押え材と、支持材の上面及び押え材の下面にそれぞれ固定された弾性材と、前記構成の屋根材とを有して構成することができる。
詳しくは、図2はかかる簡易屋根の支持材と押え材とで屋根材を支持する部分の拡大断面を示している。支持材5は、その上面両側に凹溝51、51がそれぞれ形成され、両凹溝51内に弾性体7、7の端部を固定してある。押え材6は、支持材5の上面に重なる長尺材であり、その下面両側に凹溝61、61がそれぞれ形成され、両凹溝61内に弾性体7、7の端部を固定してある。弾性体7は、天然ゴムや合成ゴム、合成樹脂材などの弾性材からなるパッキンであり、前記の通り支持材5と押え材6に設けた凹溝51、61に端部を嵌合させて両部材の表面に一体に固定してある。支持材5と押え材6は、支持材5の上面に押え材6を被せ、押え材6の頂面からボルト8を支持材5に螺合した状態で、支持材5の上面に固定した弾性体7と押え材6の下面に固定した弾性体7との間に屋根材1の端部が嵌入可能な幅の溝である保持部9を構成し、ボルト8を締め付けて両部材の間隙を狭めることにより、屋根材1の端部を弾性体7で押圧して、当該端部を挟持固定するように設けてある。
本発明の簡易屋根によれば、保持部9内に屋根材1の端部を挟持固定させた状態で、図3に示されるように、屋根材1の端部表面に設けた摩擦抵抗増加処理部3Aである凹凸部3の凹凸に弾性体7が入り込み且つ密着して接合するため、強風を受けて屋根材1の端部を保持部9から引き抜く方向の力が働いても、屋根材1の端部と弾性体7の表面間に大きな摩擦力が作用して端部を保持部9内に押し止め、端部が保持部9から引き抜かれることを防止することができる。図示されているように、凹凸部3は屋根材1の端部縁部に亘って形成してあるので、端部の変位に対して摩擦抵抗力を持続的に作用せしめ、屋根材1の端部が保持部9から完全に抜け切るまで摩擦抵抗力が作用し、屋根材1の端部の保持部9からの脱落防止に極めて有効である。
Moreover, the simple roof of this invention is the same as the conventional simple roof shown in FIG. 13, the support | pillar, the support material arranged in parallel by the predetermined interval on the upper part of the support | pillar, and the said support material above a support material. The presser material provided such that the distance between the support member and the support member can be adjusted, the elastic member fixed to the upper surface of the support member and the lower surface of the presser member, and the roof member having the above-described structure.
In detail, FIG. 2 has shown the expanded cross section of the part which supports a roofing material with the supporting material and pressing material of this simple roof. The support material 5 has concave grooves 51, 51 formed on both sides of the upper surface thereof, and ends of the elastic bodies 7, 7 are fixed in the both concave grooves 51. The presser material 6 is a long material that overlaps the upper surface of the support material 5, and concave grooves 61, 61 are formed on both sides of the lower surface, and the ends of the elastic bodies 7, 7 are fixed in the both concave grooves 61. is there. The elastic body 7 is a packing made of an elastic material such as natural rubber, synthetic rubber, or synthetic resin material. As described above, the end portion is fitted into the concave grooves 51 and 61 provided in the support material 5 and the presser material 6. It is fixed integrally to the surface of both members. The support member 5 and the presser member 6 are elastically fixed to the upper surface of the support member 5 with the presser member 6 covered on the upper surface of the support member 5 and the bolts 8 screwed to the support member 5 from the top surface of the presser member 6. Between the body 7 and the elastic body 7 fixed to the lower surface of the presser member 6, a holding portion 9, which is a groove having a width into which the end portion of the roofing material 1 can be fitted, is formed, and the bolt 8 is tightened to form a gap between the two members. By narrowing, the end portion of the roofing material 1 is pressed by the elastic body 7 so that the end portion is sandwiched and fixed.
According to the simple roof of the present invention, the frictional resistance increasing process provided on the end surface of the roofing material 1 as shown in FIG. 3 in a state where the end of the roofing material 1 is sandwiched and fixed in the holding portion 9. Since the elastic body 7 enters and closely adheres to the unevenness of the uneven portion 3 that is the portion 3A, the roofing material 1 even if a force in the direction of pulling out the end of the roofing material 1 from the holding portion 9 is applied due to strong wind. It is possible to prevent the end portion from being pulled out of the holding portion 9 by applying a large frictional force between the end portion of the elastic member 7 and the surface of the elastic body 7 to press the end portion into the holding portion 9. As shown in the drawing, the uneven portion 3 is formed over the edge of the roof material 1, so that a frictional resistance force is continuously applied to the displacement of the edge portion, and the end of the roof material 1. Friction resistance acts until the part is completely removed from the holding part 9, and is extremely effective in preventing the end of the roof material 1 from falling off the holding part 9.
