【考案の詳細な説明】 この考案は母屋を最低一本でも可とし、垂木を省略して
材料の削減と組立工数の簡略化を計ったテラス屋根に関
するものである。[Detailed description of the invention] This invention relates to a terrace roof that allows for at least one main building and omit rafters to reduce materials and simplify assembly man-hours.

従来のテラス屋根は左右一対の側板の間に、複数本の垂
木と側板と平行に適宜の間隔をもって配設するとともに
、その垂木に対して直角方向に延びる複数本の母屋を垂
木で支持し、かつ、両側板に連結固定して、この母屋に
波板を載置し固定している。Conventional terrace roofs have a plurality of rafters placed between a pair of left and right side plates at appropriate intervals parallel to the side plates, and a plurality of purlins extending perpendicularly to the rafters are supported by the rafters. , is connected and fixed to both side plates, and a corrugated plate is placed and fixed on this main building.

このように、複数の垂木と母屋を必要とした原因はこれ
らの部材の強度が劣り、かつテラス屋根に加わる風圧は
意外に大きいからで゛あるが、上述のような構造の従来
のテラス屋根は使用材料数が多く取付けるための工数も
多く、経済り並びに施工上好ましくないものであった。In this way, the reason why multiple rafters and purlins were required is that these members have poor strength and the wind pressure applied to terrace roofs is unexpectedly large. However, conventional terrace roofs with the structure described above This method requires a large number of materials and a large number of man-hours for installation, which is unfavorable in terms of economy and construction.

この考案は上記の点に鑑みてなされたものであり、母屋
を最低一本でも可とするとともに、垂木を全て省略する
ことにより、材料の可及的節減、施工の簡略化及びテラ
ス屋根自体のコスト及び取付はコストの低減を可能にし
、しかも、耐風圧強度の点においても何ら支障のないテ
ラス屋根を提供することを目的とする。This idea was made in view of the above points, and by allowing at least one main building and omitting all rafters, it was possible to save materials, simplify construction, and improve the structure of the terrace roof itself. The purpose of the present invention is to provide a terrace roof that enables cost reduction in terms of cost and installation, and also has no problems in terms of wind pressure resistance.

いる。Then, both longitudinal ends of the square tube portion 5a are tightly fitted between the third projecting edge 2d and the fourth projecting edge 2e of the side beam 2, and the locking edge 5
b, 5b', inserted through the hole of the second projecting edge 2C, and tightening the nut N3 to the lower end of the bolt B3 that penetrates the third projecting edge 2d, the upper wall 5ax, and the lower wall 5a2. 5 is bridged and fixed between the left and right side beams 2, 2'.

上述のように母屋５は角筒部５ａを有するから、長手方
向に対して直角に加わる力に対する耐力が非常に大きく
、また、上方に延びる係止縁５ｂ、５ｂ’が補強作用を
するので、母屋の強度は特に大きい。As mentioned above, since the main building 5 has the rectangular tube part 5a, it has a very high resistance to the force applied perpendicularly to the longitudinal direction, and the locking edges 5b and 5b' extending upward have a reinforcing effect. The strength of the main building is particularly great.

従って、このような母屋は最低一本だけでも足り、側桁
の長さ、すなわち、軒桁から雨樋までの間隔が特に大き
い場合は、複数本の母屋が用いられる。Therefore, at least one such purlin is sufficient, and if the length of the stringer, that is, the distance from the eaves girder to the rain gutter is particularly large, multiple purlins are used.

縁６Ｃを第１突縁２ｂと第２突縁２Ｃの間に嵌合する。In this way, the eave girder 1 described above, the left and right side girders 2,
2', the rain gutter 3, and the main building 5 are connected in a diagonal or cross-shaped pattern, then a corrugated sheet 6 is placed thereon, and the lower edge 6a of the corrugated sheet is first connected to the rain gutter 3. After inserting the corrugated plate into the bridge portion of the eave girder 1 until it is stopped by the outer wall 3e, insert the upper edge 6b of the corrugated sheet into the first bridge portion of the eave girder 1.
The corrugated plate is moved in the direction of the eave girder by fitting between the second projecting edge 1b and the IC, and the upper end edge 6b is fitted between the projecting edge 1b and the IC, and the corrugated plate is moved in the direction of the side girder. It moves to fit one widthwise end edge 6C between the first projecting edge 2b and the second projecting edge 2C.

波板は幅方向は複数枚連設され、他の波板の幅方向他端
縁を他の側桁の第１突縁と第２突縁の間に嵌合する。A plurality of corrugated plates are arranged in a row in the width direction, and the other end edge of the other corrugated plate in the width direction is fitted between the first flange and the second flange of the other stringer.

Opposing edges 2aa, 2a4 integrally formed at the lower end of the
The upper end of the strut 4 is cut out according to the width of the strut, and the upper end of the strut 4 is tightly inserted between the inner wall 2a1 and the outer wall 2a2, and the upper end surface of the strut is brought into contact with the lower surface of the earthen wall of the stringer. With the outer wall 2a2. Pillar 4. It is fixed to the side beam 2 by tightening a nut N4 to a bolt B4 that passes through the inner wall two a1.

節減できるとともに、組立工数が簡略化される。As described above, according to this invention, the main building integrally has a square tube portion and at least one locking edge that extends upward from the square tube portion and can lock the hook for fixing the corrugated plate. It has enough strength to withstand the strong wind force that is applied perpendicular to the longitudinal direction of the main building through the board, so the rafters that were conventionally used in large numbers can be omitted altogether, and it is also possible to have at least one main building. Therefore, the materials used for the terrace roof can be significantly reduced, and the number of assembly steps can be simplified.
