【発明の詳細な説明】
本発明は家屋の増築に際し、既設の三角トラスをそのま
ま使用することのできる増築用トラスに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an extension truss that allows an existing triangular truss to be used as is when extending a house.
家屋を増築する際は、既設の三角トラスより大きな三角
トラスが必要となる。When expanding a house, a larger triangular truss is required than the existing one.
この場合、通常は大きな三角トラスを新たに作製するの
であるが、それでは、既設の三角トラスを廃棄しなけれ
ばならず、資材の無駄使いになるし、また新たな三角ト
ラスな用いることによって増築費用も嵩むものである。In this case, usually a new large triangular truss is manufactured, but in that case the existing triangular truss would have to be discarded, which would be a waste of materials, and the use of a new triangular truss would increase the cost of building an extension. It is also bulky.
本発明はかかる点にあって、既設の三角トラスをそのま
ま一部に利用でき、それでいて全体としての強度も十分
に強（することのできるという極めて有用な増築用トラ
スを提供しようとするものである。In view of this, the present invention aims to provide an extremely useful extension truss in which the existing triangular truss can be used in part as is, and the overall strength is sufficiently strong. .
以下に本発明に係る増築用トラスを図面に示す一実施例
に基づいて説明すると、増築用トラスＡは、台形トラス
１と小さな三角トラス２と既設の三角トラス３とを次の
如（接合して既設の三角トラス３よりも大きな三角トラ
スに構成されている。The extension truss A according to the present invention will be described below based on an embodiment shown in the drawings. It is constructed as a larger triangular truss than the existing triangular truss 3.
即ち、台形トラス１の一側辺１ａに小さな三角トラス２
の一側辺２ａを接合して四辺形トラス４を構成し、該四
辺形トラス４の一辺、つまシ台形トラス１の上辺１ｂと
三角トラス２の＝辺２ｂとで構成された辺を既設の三角
トラス３の一側辺３ａに接合し、且つ前記台形トラス１
の一側辺１ａと小さな三角トラス２の一側辺２ａとの接
合部を増築用トラスＡの頂部Ｔを通る垂直線Ｐに沿うよ
うに位置させてなるという構成である。That is, a small triangular truss 2 is placed on one side 1a of the trapezoidal truss 1.
One side 2a is joined to form a quadrilateral truss 4, and one side of the quadrilateral truss 4, the side composed of the upper side 1b of the trapezoidal truss 1 and the = side 2b of the triangular truss 2, is connected to the existing side. It is joined to one side 3a of the triangular truss 3, and the trapezoidal truss 1
The structure is such that the joint between one side 1a and one side 2a of the small triangular truss 2 is positioned along a vertical line P passing through the top T of the extension truss A.
前記台形トラス１と三角トラス２との接合及びこれらに
て構成される四辺形トラス４と既設の三角トラス３との
接合はボルト及び６接等により行なうことができる。The trapezoidal truss 1 and the triangular truss 2 can be joined together, and the quadrilateral truss 4 made up of them can be joined to the existing triangular truss 3 using bolts, hexagonal joints, or the like.
前記台形トラス１の大きさは、どの程度の大きさの家屋
に増築するかにより一義的に定まる。The size of the trapezoidal truss 1 is uniquely determined by the size of the house to which it will be added.
三角トラス２の大きさは、台形トラス１と共に四辺形ト
ラス４を構成するという条件及び、四辺形トラス４と既
設の三角トラス３とによって大きな三角トラスを構成す
るという条件との２条件によって台形トラス２の大きさ
が決まれば一義的に定まる。The size of the triangular truss 2 is determined by two conditions: that it forms a quadrilateral truss 4 together with the trapezoidal truss 1, and that the quadrilateral truss 4 and the existing triangular truss 3 form a large triangular truss. Once the size of 2 is determined, it is uniquely determined.
尚、台形トラス１と三角トラス２とで四辺形トラス４を
構成するとは１台形トラス１の一側辺１ａと三角トラス
２の一側辺２ａの長さが等しく、両者１ａ、２ａを接合
した場合台形トラス１の上辺１ｂと三角トラス２の一辺
２ｂとが一直線上に並んで文字通り四辺形を形成するこ
とをいう。In addition, when a quadrilateral truss 4 is constituted by a trapezoidal truss 1 and a triangular truss 2, one side 1a of the trapezoidal truss 1 and one side 2a of the triangular truss 2 are equal in length, and both 1a and 2a are joined. In this case, the upper side 1b of the trapezoidal truss 1 and the one side 2b of the triangular truss 2 are aligned in a straight line to literally form a quadrilateral.
また四辺形トラス４と既設の三角トラス３とで増築用ト
ラスＡ即ち、大きな三角トラスを構成するとは、台形ト
ラス１の斜辺１Ｃと既設の三角トラス３の下辺３ｂとが
一直線に並び、また小さな三角トラス２の一辺２Ｃと既
設の三角トラス３の一側辺３Ｃとが一直線に並び、これ
ら直線及び台形トラスの下辺１ｄＹ各辺とする文字通り
三角形を形成することをいう。Furthermore, when we say that the quadrilateral truss 4 and the existing triangular truss 3 constitute the extension truss A, that is, a large triangular truss, we mean that the oblique side 1C of the trapezoidal truss 1 and the lower side 3b of the existing triangular truss 3 are aligned in a straight line, and that the One side 2C of the triangular truss 2 and one side 3C of the existing triangular truss 3 are aligned in a straight line, literally forming a triangle with these straight lines and the lower side 1dY of the trapezoidal truss.
図中５・・・は足間プレートである。5 in the figure is an interfoot plate.
本発明に係る増築用トラスは上述の如く構成したため、
次のような効果をもつ。Since the extension truss according to the present invention is constructed as described above,
It has the following effects.
■ 既設の三角トラスなそのまま一部に使用するため、
資材の節約及び大幅な増築費用の低減が図れる。■ Because the existing triangular truss will be used as is,
It is possible to save on materials and significantly reduce the cost of expansion.
■ 台形トラス１の一側辺１ａと三角トラス２の一側辺
２ａとの接合部は、増築用トラスＡの頂部Ｔ’に通る垂
直線に沿って位置されているため、該接合部が増築用ト
ラスＡの中心の束材として作用するので、増築用トラス
に十分な強度をもたせることができる。■ The joint between one side 1a of the trapezoidal truss 1 and one side 2a of the triangular truss 2 is located along a vertical line passing through the top T' of the truss A for extension, so the joint Since it acts as a bundle material at the center of the truss A, the truss for extension can have sufficient strength.
