【発明の詳細な説明】
この発明は開口部のアーチ枠等に使用するアーチ形建築
用材に関するもので、製造を容易でかつ強度を向上させ
ることを目的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an arch-shaped building material used for arch frames of openings, etc., and aims to facilitate manufacturing and improve strength.
この発明の一実施例を第１図ないし第４図を用いて説明
する。An embodiment of the present invention will be described with reference to FIGS. 1 to 4.
すなわち、このアーチ形建築用材は第１図に示すように
、長手方向に半円形に湾曲したアーチ形板状体１であっ
て、この板状体１はその厚み方向に積層・接着した複数
の単板層２からなる。That is, as shown in FIG. 1, this arch-shaped building material is an arch-shaped plate-shaped body 1 curved semicircularly in the longitudinal direction, and this plate-shaped body 1 has a plurality of layers laminated and glued in the thickness direction. Consists of 2 veneer layers.
各単板層２は、板状体１の長手方向に対して傾斜して配
列され側面を互いに突合わせた複数の単板３から構成さ
れる。Each veneer layer 2 is composed of a plurality of veneers 3 that are arranged obliquely with respect to the longitudinal direction of the plate-like body 1 and have their side surfaces abutted against each other.
この建築用材の製造はつぎのようにして行う。This construction material is manufactured as follows.
すなわち、ロークリまたはスライス単板を一定の幅にカ
ットし、これら単板の長手方向を滑り刃継ぎまたは突付
けで継合せたのち、これら単板をフープ状に巻き取る。That is, the veneers are cut into a certain width, joined together in the longitudinal direction by sliding blade joints or butts, and then rolled up into a hoop shape.
つぎに、第２図に示すようにフープ状に巻き取った複数
の単板３を接着剤を塗布しながら大直径の鉄芯４に螺旋
状に一度に巻き込み、同時にプレスを行うことにより連
続的に円筒状のものを形成する。Next, as shown in Fig. 2, a plurality of veneers 3 wound into a hoop shape are wound spirally around a large-diameter iron core 4 at once while applying adhesive, and pressed at the same time to create a continuous form a cylindrical shape.
接着剤の乾燥後、鉄芯４を抜き取る。After the adhesive dries, the iron core 4 is removed.
そののち、第２図に示す一点鎖線５の位置で切断するこ
とにより第３図に示すように円筒半径が大きく、軸方向
に短く、厚み方向に隣り合う単板３の巻付方向が同一方
向であるリング状体６を得る。After that, by cutting at the position of the dashed-dotted line 5 shown in FIG. 2, the cylindrical radius is large, the veneer 3 is short in the axial direction, and the winding direction of the adjacent veneers 3 in the thickness direction is the same as shown in FIG. 3. A ring-shaped body 6 is obtained.
このリング状体６を第３図の一点鎖線７で示す位置で半
分に切断することにより、第１図に示すようなアーチ形
建築用板を得ることができる。By cutting this ring-shaped body 6 in half at the position shown by the dashed line 7 in FIG. 3, an arch-shaped building board as shown in FIG. 1 can be obtained.
この建築用板は第４図に示すようにアーチ枠の頭部８と
して利用できる。This architectural board can be used as the head 8 of an arch frame, as shown in FIG.
すなわち、アーチ枠の頭部８の両端面にそれぞれ板９を
接続することにより簡単にアーチを形成できる。That is, the arch can be easily formed by connecting the plates 9 to both end faces of the head 8 of the arch frame.
このように構成しためめ、従来のようにまず板状の化粧
合板を作成しこれをプレス等により折り曲げて製造する
方法に比してアーチ形築用板を容易に製造することがで
きる。With this structure, the arch-forming board can be manufactured more easily than the conventional method in which a plate-shaped decorative plywood is first prepared and then bent by a press or the like.
また、単板３を螺旋状に巻き付け、かつ厚み方向で各単
板層２を一体に接着しているために強度も大きくなる。Moreover, since the veneer 3 is wound spirally and each veneer layer 2 is bonded together in the thickness direction, the strength is also increased.
なお、この実施例では、厚み方向に隣り合う単板の巻付
方向を同一方向としたが、各層ご吉に単板の巻付方向が
相互にほぼ直交するようにしてもよい。In this embodiment, the veneers adjacent in the thickness direction are wound in the same direction, but the veneers may be wound in substantially orthogonal directions for each layer.
以上のように、この発明のアーチ形建築用材は、長手方
向に半円形に湾曲したアーチ形板状体であって、この板
状体はその厚み方向に積層・接着した複数の単板層から
なり、しかも各単板層は前記板状体の長手方向に対して
傾斜しかつ側面を互いに突合せた複数の単板からなるた
め、製造が容易でかつ強度にすぐれているという効果が
ある。As described above, the arch-shaped construction material of the present invention is an arch-shaped plate-shaped body curved semicircularly in the longitudinal direction, and this plate-shaped body is made of a plurality of veneer layers laminated and bonded in the thickness direction. Moreover, since each veneer layer is composed of a plurality of veneers that are inclined with respect to the longitudinal direction of the plate-like body and whose side surfaces are abutted against each other, the veneer layer is easy to manufacture and has excellent strength.
