Description

本発明は、ラチス板構造に関し、特に、既設の一方部材と間隔をおいて対向する新たな他方部材とをラチス板の連結でトラス体にする際の利用に向くラチス板構造の改良に関する。 The present invention relates to a lattice plate structure, and more particularly, to an improvement of a lattice plate structure suitable for use in forming a truss body by connecting a new other member facing an existing one member with a space therebetween.

たとえば、ビニールハウスは、多くの場合に、長手方向に間隔を有して整列する複数のアーチフレームを同じく長手方向に配設される棟部材および軒部材で連結して、さらには、要する場合にアーチフレームに梁部材を配設して骨組みを形成し、この骨組にビニールフィルムあるいはビニールシートを展設して形成される。 For example, in a greenhouse, in many cases, a plurality of arch frames that are aligned at intervals in the longitudinal direction are connected by a ridge member and an eaves member that are also arranged in the longitudinal direction, and further, when necessary. A beam member is disposed on the arch frame to form a frame, and a vinyl film or a vinyl sheet is spread on the frame.

このとき、アーチフレーム、棟部材および軒部材、さらに、梁部材は、ビニールハウスの骨組を形成する構造部材となるので、所定の機械的強度を具有するように形成されるのが常態である。 At this time, since the arch frame, the ridge member, the eaves member, and the beam member are structural members that form the framework of the greenhouse, it is normally formed so as to have a predetermined mechanical strength.

そして、構造部材としての所定の強度を具有する方策としては、従来から種々の提案があるが、たとえば、特許文献１に開示の提案にあっては、内外となる二本のパイプを連結プレート、すなわち、ラチス板（ウェブとも称する）で繋いでトラス体にするとしている。 And, as a measure having a predetermined strength as a structural member, there are various proposals from the past. For example, in the proposal disclosed in Patent Document 1, two pipes that are inside and outside are connected to a connecting plate, That is, a truss body is formed by connecting with a lattice board (also referred to as a web).

それゆえ、このトラス体からなる、たとえば、アーチフレームを備えるビニールハウスにあっては、構造部材が所定の機械的強度を具有することになるから、積雪による縦方向の外力作用や風による横方向の外力作用に十分に対抗し得ることになる。 Therefore, in a greenhouse made of this truss body, for example, with an arch frame, the structural member has a predetermined mechanical strength. It will be able to fully counteract the external force action.

特許第３９８６００２号公報Japanese Patent No. 3986002

しかしながら、上記した特許文献１に開示の提案にあっては、トラス体がビニールハウスにおける所定の機械的強度を担保する点で、基本的に問題がある訳ではないが、実施をする上で、些かの不具合があると指摘される可能性がある。 However, in the proposal disclosed in Patent Document 1 described above, the truss body is not necessarily basically problematic in terms of ensuring a predetermined mechanical strength in the greenhouse, It may be pointed out that there is a minor defect.

すなわち、上記した特許文献１に開示の提案にあって、相対向して一対となる一方部材と他方部材の両部材をラチス板で連結してトラス体にするのについては、従来からの溶接を利用することになる。 That is, in the proposal disclosed in the above-mentioned Patent Document 1, a conventional truss body is formed by connecting a pair of one member and the other member facing each other with a lattice plate. Will be used.

しかし、既存のビニールハウスにあって、アーチフレームなどの既設の一方部材に新たに他方部材を対向させて両部材をラチス板で連結してトラス体にするとしても、既設のビニールハウスがビニールフィルムあるいはビニールシートを骨組みに展設しているので、ラチス板の連結に溶接を利用できない。 However, in an existing greenhouse, even if the other member is newly opposed to one existing member such as an arch frame and both members are connected by a lattice plate to form a truss body, the existing greenhouse is still a vinyl film. Or since the vinyl sheet is spread out in the framework, welding cannot be used to connect the lattice plates.

そこで、たとえば、本願の出願人が先になした特願２０１３−１３１６８３号に開示するように、ラチス板を二つとし、また、この二つのラチス板の積層する基端部を適宜手段で枢支してＶ字状に組み、このＶ字状に組んだ二つのラチス板を連結具の利用で一方部材および他方部材に連結することを提案できる。 Therefore, for example, as disclosed in Japanese Patent Application No. 2013-131683 previously filed by the applicant of the present application, there are two lattice plates, and the base end portion where these two lattice plates are stacked is pivoted by an appropriate means. It can be proposed that the two lattice plates assembled in a V shape are supported and connected to one member and the other member by using a connector.

そして、この提案による場合には、既設の一方部材に新たに他方部材を対向させるとき一方部材と他方部材との間の間隔が一定にならずして区々になることが多いので、Ｖ字状に組んだ二つのラチス板にあっては、一のラチス板が他のラチス板に対して回動自在な態勢のままに維持され、二つのラチス板がなす角度を特定するように固定されないことが肝要になる。 In the case of this proposal, when the other member is newly opposed to the existing one member, the distance between the one member and the other member is often not constant, and thus becomes V-shaped. In the two lattice plates assembled in a shape, one lattice plate is maintained in a state of being rotatable with respect to the other lattice plates, and is not fixed so as to specify an angle formed by the two lattice plates. It becomes important.

しかし、既設の一方部材とこれに対向する新たな他方部材とを連結具と共にＶ字状に組んだ二つのラチス板を利用して連結するのにあって、一のラチス板が他のラチス板に対して回動自在なままであると、連結作業の際に一のラチス板の他のラチス板に対する徒な回動を阻止する手順が必須になり、連結作業を面倒にすることが危惧される。 However, when one existing member and another new member opposite to this member are connected together using two lattice plates assembled in a V shape together with a connector, one lattice plate is the other lattice plate. If it remains pivotable, the procedure for preventing the pivoting of one lattice plate relative to the other lattice plate becomes necessary during the connection work, and there is a concern that the connection work will be troublesome. .

本発明は、上記した現状を鑑みて創案されたものであって、その目的とするところは、既設の一方部材と対向する新たな他方部材とを二つのラチス板の連結でトラス体にするのに最適となるラチス板構造を提供することである。 The present invention was devised in view of the above-described present situation, and the object of the present invention is to make a truss body by connecting two existing lattice members to a new other member facing one existing member. It is to provide a lattice plate structure that is optimal for the above.

上記した目的を達成するために、本発明によるラチス板構造の構成を、相対向して一対となる一方部材と他方部材とを連結してトラス体を形成する二つのラチス板を備えるラチス板構造において、上記二つのラチス板の各基端部を積層し同軸に枢支してＶ字状に組み上記一のラチス板を上記他のラチス板に対して回動自在にし、上記他のラチス板が回動する上記一のラチス板の側面を当接させるストッパ部を上面に備え、上記ストッパ部は、上記一のラチス板の一側面を当接させる一当接部を有する一のリブと、上記一のリブと分離形成されるとともに上記一のラチス板の他側面を当接させる他当接部を有する他のリブとを有し、上記一方のラチス板が一方向に回動して一側面が上記一当接部に当接すると上記二つのラチス板が一の角度をなしてＶ字状になると共に上記一方のラチス板が逆方向に回動して他側面が上記他当接部に当接すると上記二つのラチス板が他の角度をなしてＶ字状になり、上記一のラチス板の先端部と上記他のラチス板の先端部とを結ぶ基準線に直角に連結すると共に上記二つのラチス板の積層する基端部に連結する垂直線の長さを長短変化させるとする。 In order to achieve the above-described object, the structure of the lattice plate structure according to the present invention includes a lattice plate structure including two lattice plates that form a truss body by connecting a pair of one member and the other member facing each other. In this case, the base ends of the two lattice plates are stacked and coaxially supported so as to be assembled in a V shape so that the one lattice plate is rotatable with respect to the other lattice plate, and the other lattice plate is A stopper portion that contacts the side surface of the one lattice plate that rotates, and the stopper portion includes one rib that has one contact portion that contacts one side surface of the one lattice plate; And another rib having another abutting portion that is formed separately from the one rib and that abuts the other side surface of the one lattice plate. sides it the angle of the upper Symbol two lattice plate one when brought into contact the one contact portion Other aspects rotates said one lattice plate in the opposite direction together becomes V-shaped Te is above SL two lattice plate at an other angle in a V-shape when in contact with the other contact portion The length of the vertical line connected to the base end portion where the two lattice plates are stacked is connected to the reference line connecting the tip portion of the one lattice plate and the tip portion of the other lattice plate at a right angle. Let's change.

それゆえ、本発明のラチス板構造にあっては、相対向して一対となる一方部材と他方部材とをＶ字状に組んだ二つのラチス板を利用して連結するとき、一のラチス板を他のラチス板に対して一方向、たとえば、時計方向に回動するとき、二つのラチス板のなす角度を大きく、たとえば、９０度にして、二つのラチス板が表出する垂直線の長さを小さくでき、反対に、一のラチス板を他のラチス板に対して他方向、たとえば、反時計方向に回動するとき、二つのラチス板のなす角度を小さく、たとえば、９０度未満にして、二つのラチス板が表出する垂直線の長さを大きくできる。 Therefore, in the lattice plate structure of the present invention, when two lattice plates in which a pair of one member and the other member which are opposed to each other are connected together using a V-shape are connected, one lattice plate is used. Is rotated in one direction with respect to the other lattice plate, for example, clockwise, the angle formed by the two lattice plates is increased, for example, 90 degrees, and the length of the vertical line that the two lattice plates are exposed to. On the other hand, when one lattice plate is rotated in the other direction, for example, counterclockwise, with respect to the other lattice plate, the angle formed by the two lattice plates is small, for example, less than 90 degrees. Thus, the length of the vertical line that the two lattice plates appear can be increased.

その結果、本発明のラチス板構造によれば、既設の一方部材に新たに他方部材を対向させて両部材をラチス板で連結する際に、両部材間の間隔が一定にならずして区々になる場合にも、両部材をＶ字状に組んだ二つのラチス板の連結でトラス体にすることが可能になる。 As a result, according to the lattice plate structure of the present invention, when the other member is newly opposed to the existing one member and the two members are connected by the lattice plate, the interval between the two members is not constant. Even in such a case, it becomes possible to form a truss body by connecting two lattice plates in which both members are assembled in a V shape.

また、本発明のラチス板構造によれば、一方部材と他方部材とをＶ字状に組んだ二つラチス板で連結する際に、二つのラチス板を広狭いずれかの角度のＶ字状に仮固定状態にすることが可能になり、二つのラチス板がＶ字状に仮固定されない状態にある、すなわち、一のラチス板が他のラチス板に対して徒に回動して仮固定状態を具現化できない場合に比較して、二つのラチス板で両部材を連結してトラス体にする際の作業性を向上させる。 Further, according to the lattice plate structure of the present invention, when the one member and the other member are connected by two lattice plates assembled in a V shape, the two lattice plates are formed in a V shape having any one of wide and narrow angles. It is possible to make a temporarily fixed state, and the two lattice plates are not temporarily fixed in a V shape, that is, one lattice plate is rotated relative to another lattice plate and temporarily fixed. Compared to the case where the material cannot be embodied, the workability when connecting the two members with two lattice plates to form a truss body is improved.

そして、本発明のラチス板構造によれば、他のラチス板に設けられるストッパ部は、他のラチス板を裏側からする加圧成形、打ち抜き成形あるいは折り曲げ成形で形成し得るので、この種のストッパ部を設けるのにあって、他部材を利用したり、他部材を溶接したりする場合に比較して、ストッパ部の形成作業を容易にする。 According to the lattice plate structure of the present invention, the stopper portion provided on the other lattice plate can be formed by pressure molding, punching molding or bending molding of the other lattice plate from the back side. In providing the portion, it is easier to form the stopper portion than when other members are used or other members are welded.

そしてまた、本発明のラチス板構造によれば、ストッパ部は、他のラチス板に設けられるので、一のラチス板にあっては、ストッパ部を設けない平板状に形成されることで足り、二つのラチス板を同じ態様に形成する場合に比較して、経済的に有利になる。 And, according to the lattice plate structure of the present invention, since the stopper portion is provided on another lattice plate, it is sufficient for one lattice plate to be formed in a flat plate shape without the stopper portion, Compared to the case where the two lattice plates are formed in the same mode, it is economically advantageous.

以下に、図示した実施形態に基づいて、本発明を説明するが、本発明のラチス板構造は、図示する実施形態では、ビニールハウス（図示せず）の骨組を形成する構造部材、たとえば、アーチフレームをトラス体にする際に利用される。 In the following, the present invention will be described based on the illustrated embodiment. In the illustrated embodiment, the lattice board structure of the present invention is a structural member that forms the framework of a greenhouse (not shown), for example, an arch. Used when making the frame a truss.

ちなみに、本発明の意図するところからすれば、本発明のラチス板構造は、ビニールハウスにおける骨組を形成する他の構造部材、すなわち、棟部材や軒部材、さらには、梁部材をトラス体にする際に利用されても良く、また、ビニールハウスにおける骨組みに代えて、図示しないが、温室の合掌造構造に組み上げられる骨組をトラス体にする際に利用されても良い。 By the way, from the intention of the present invention, the lattice board structure of the present invention has other structural members forming a framework in the greenhouse, that is, a ridge member, an eaves member, and a beam member as a truss body. Although not shown, it may be used when a truss is used instead of the frame in the greenhouse.

そして、ビニールハウスについて少し説明すると、一般には、ビニールハウスにおける頂部の延在方向たる長手方向に間隔を有して整列する複数のアーチフレームを同じくビニールハウスの長手方向に配設される棟部材および軒部材で連結して長手方向に倒れないようにし、さらには、要する場合に、アーチフレームに梁部材を、すなわち、ビニールハウスの短手方向に設けられる梁部材を配設して骨組みを形成し、この骨組にビニールフィルムあるいはビニールシートを展設して形成される。 Then, to explain a little about the greenhouse, in general, a ridge member that is arranged in the longitudinal direction of the greenhouse, and a plurality of arch frames that are arranged at intervals in the longitudinal direction that is the extending direction of the top of the greenhouse, and Connect with eaves members so that they do not fall down in the longitudinal direction, and if necessary, form a framework by arranging beam members on the arch frame, that is, beam members provided in the short direction of the greenhouse. The film is formed by spreading a vinyl film or a vinyl sheet on the frame.

このとき、アーチフレームは、金属製の長尺の丸パイプをアーチ状に折り曲げて形成され、ビニールハウスの側面を形成する立ち上がり部と、この立ち上がり部に連続してビニールハウスの屋根を形成するアーチ部とを備える。 At this time, the arch frame is formed by bending a long metal round pipe into an arch shape, a rising portion that forms the side surface of the greenhouse, and an arch that continuously forms the roof of the greenhouse in the rising portion. A part.

そして、軒部材および棟部材は、アーチフレームと同様に、金属製の長尺の丸パイプで形成され、専用の連結具が利用されるなどして複数のアーチフレームの等間隔に起立する状態を維持する。 And the eaves member and the ridge member are formed of a long metal round pipe, like the arch frame, and are in a state of standing up at equal intervals of a plurality of arch frames by using a dedicated connector or the like. maintain.

ちなみに、軒部材は、等間隔に起立する複数のアーチフレームにおける立ち上がり部の上端部、アーチ部の下端部、あるいは、両者の接続部をビニールハウスの長手方向に繋ぎ、棟部材は、等間隔に起立する複数のアーチフレームにおける頂部、すなわち、アーチ部の頂部をビニールハウスの長手方向に繋ぐ。 By the way, the eaves member connects the upper end part of the rising part, the lower end part of the arch part, or the connection part between them in the longitudinal direction of the greenhouse in the plurality of arch frames standing up at equal intervals. The top portions of the plurality of standing arch frames, that is, the top portions of the arch portions are connected in the longitudinal direction of the greenhouse.

戻って、本発明のラチス板構造は、以上のように形成されるビニールハウスの骨組を形成する構造部材たるアーチフレーム、棟部材、軒部材、さらには、梁部材をトラス体にするのに利用される。 Returning, the lattice board structure of the present invention is used to form a truss body for an arch frame, a ridge member, an eaves member, and further a beam member as a structural member forming the framework of the greenhouse formed as described above. Is done.

トラス体は、たとえば、図１に示すように、相対向して一対となる一方部材Ｐ１と他方部材Ｐ２を複数の、すなわち、図示するところでは、一のラチス板１および他のラチス板２となる二つのラチス板１，２で連結することで形成される。 For example, as shown in FIG. 1, the truss body includes a plurality of one member P1 and the other member P2 that are opposed to each other, that is, in the illustrated case, one lattice plate 1 and another lattice plate 2 The two lattice plates 1 and 2 are connected to each other.

そして、トラス体にあっては、一方部材Ｐ１と他方部材Ｐ２とが軸線方向に互いにずれるようになるとき、一のラチス板１が、たとえば、引っ張り力を受け、他のラチス板２が圧縮力を受け、結果として、全体として圧縮力を大きくし、また、引っ張り力を大きくする。 In the truss body, when one member P1 and the other member P2 are displaced from each other in the axial direction, one lattice plate 1 receives, for example, a tensile force, and the other lattice plate 2 compresses. As a result, the compressive force is increased as a whole, and the tensile force is increased.

トラス体が以上のように形成されるとき、本発明のラチス板構造は、図２に示すように、相対向して一対となる一方部材Ｐ１と他方部材Ｐ２とを連結してトラス体を形成する二つのラチス板１，２を備え、一方部材Ｐ１および他方部材Ｐ２への二つのラチス板１，２の連結には、連結具Ｊを利用する。 When the truss body is formed as described above, the lattice plate structure of the present invention forms a truss body by connecting a pair of one member P1 and the other member P2 facing each other as shown in FIG. The connecting plate J is used for connecting the two lattice plates 1 and 2 to the one member P1 and the other member P2.

このとき、図示するところでは、一方部材Ｐ１および他方部材Ｐ２は、ビニールハウスにおける骨組みを形成する内外となるアーチフレームを想定しているが、凡そ一方部材と他方部材が相対向する一対となり、複数のラチス板の連結でトラス体になる限りには、上記の骨組を形成する棟部材や軒部材、さらには、梁部材であっても良い。 At this time, as shown in the figure, the one member P1 and the other member P2 are assumed to be arch frames that form the inside and outside of the greenhouse, and a pair of the one member and the other member face each other. As long as a truss body is obtained by connecting the lattice plates, a ridge member, an eaves member, or a beam member may be used.

また、二つのラチス板１，２、すなわち、一のラチス板１および他のラチス板２についてであるが、基本的には、図３にも示すように、同じ形態に、すなわち、基端部１ａ，２ａと先端部１ｂ，２ｂとを結ぶ軸線方向の長さを同一にし、平面視での形状を長円形とし、基端部１ａ，２ａおよび先端部１ｂ，２ｂの同じ位置に鳩目や鋲あるいはボルトなどの枢支部材（図示せず）を挿通させる軸孔１ｃ，１ｄ，２ｃ，２ｄを備える態様に形成されて良い。 Further, the two lattice plates 1 and 2, that is, one lattice plate 1 and the other lattice plate 2 are basically the same as shown in FIG. 3, that is, the base end portion. The lengths in the axial direction connecting 1a, 2a and the distal end portions 1b, 2b are made the same, the shape in plan view is an oval shape, and the eyelets and ridges are located at the same positions on the base end portions 1a, 2a and the distal end portions 1b, 2b. Or you may form in the aspect provided with the shaft holes 1c, 1d, 2c, and 2d which penetrate pivotal members (not shown), such as a volt | bolt.

一方、二つのラチス板１，２にあって、特に、他のラチス板２は、ストッパ部２１を備えることが必須となるが、一のラチス板１にあっては、ストッパ部２１を設けることを要しない。 On the other hand, in the two lattice plates 1 and 2, in particular, the other lattice plate 2 is necessarily provided with the stopper portion 21, but in the one lattice plate 1, the stopper portion 21 is provided. Is not required.

このことからして、図示する実施形態では、一のラチス板１の他のラチス板２に対する態勢を解り易くするためにも、一のラチス板１は、ストッパ部２１を備えない言わば平板状に形成されるが、一のラチス板１が他のラチス板２と同じ、すなわち、ストッパ部２１を備える同じ態様のラチス板を一のラチス板１にするとしても良いことはもちろんである。 Therefore, in the illustrated embodiment, in order to make it easier to unravel the attitude of the one lattice plate 1 with respect to the other lattice plate 2, the one lattice plate 1 has a flat plate shape without the stopper portion 21. Of course, one lattice plate 1 is the same as the other lattice plate 2, that is, the same lattice plate including the stopper portion 21 may be used as one lattice plate 1.

戻って、本発明のラチス板構造にあっては、二つのラチス板１，２の各基端部１ａ，２ａを積層し、図示しない鳩目の形成または鋲の挿し込み、あるいは、図示するボルトＢの螺入、すなわち、鳩目や鋲あるいはボルトなどの枢支部材で同軸に枢支してＶ字状に組み一のラチス板１を他のラチス板２に対してき回動自在にする。 Returning, in the lattice plate structure of the present invention, the base end portions 1a and 2a of the two lattice plates 1 and 2 are laminated, and the formation of the eyelet (not shown) or the insertion of the ridge, or the bolt B (shown) , That is, the lattice plate 1 assembled in a V-shape is pivoted coaxially by a pivotal member such as an eyelet, a collar or a bolt so that the lattice plate 1 can be rotated with respect to the other lattice plate 2.

そして、本発明のラチス板構造にあっては、図３にも示すように、他のラチス板２が回動する一のラチス板１の側面、すなわち、一側面１１および他側面１２を当接させるストッパ部２１を上面に備える。 And in the lattice board structure of this invention, as shown also in FIG. 3, the side surface of one lattice board 1 which the other lattice board 2 rotates, ie, the one side surface 11 and the other side surface 12, is contact | abutted. A stopper portion 21 is provided on the upper surface.

なお、図３において、二つのラチス板１，２の積層される基端部１ａ，２ａは、図中に符示などしないが、鳩目の形成または鋲の挿し込み、あるいは、ボルトＢの螺入などで同軸に枢支されている。 In FIG. 3, the base end portions 1a and 2a on which the two lattice plates 1 and 2 are laminated are not indicated in the drawing, but are formed with eyelets or insertion of ridges or screwed bolts B. It is pivotally supported on the same axis.

また、本発明のラチス板構造にあっては、一のラチス板１が一方向、たとえば、時計方向に回動して一側面１１をストッパ部２１に当接するとき（図３（Ａ）参照）に、一のラチス板１のさらなる回動が阻止されて、二つのラチス板１，２が一の角度、たとえば、９０度の角度をなすＶ字状に仮固定されると共に、一のラチス板１が逆方向、たとえば、反時計方向に回動して他側面１２をストッパ部２１に当接するとき（図３（Ｃ）参照）に、一のラチス板１のさらなる回動が阻止されて、二つのラチス板１，２が他の角度、たとえば、９０度未満の角度をなすＶ字状に仮固定される状態になる。 Further, in the lattice plate structure of the present invention, when one lattice plate 1 rotates in one direction, for example, clockwise, the one side surface 11 comes into contact with the stopper portion 21 (see FIG. 3A). Further, the further rotation of one lattice plate 1 is prevented, and the two lattice plates 1 and 2 are temporarily fixed in a V shape having an angle of, for example, 90 degrees, and one lattice plate When 1 rotates in the opposite direction, for example, counterclockwise and the other side surface 12 comes into contact with the stopper portion 21 (see FIG. 3C), further rotation of one lattice plate 1 is prevented, The two lattice plates 1 and 2 are temporarily fixed in a V shape having another angle, for example, an angle of less than 90 degrees.

そしてまた、本発明のラチス板構造にあっては、二つのラチス板１，２がなす角度が、言わば、広狭変化するときに、図１に示すように、一のラチス板１の先端部１ｂと他のラチス板２の先端部２ｂとを結ぶ基準線Ｔａに直角に連結すると共に二つのラチス板１，２の積層する基端部１ａ，２ａに連結する垂直線Ｔｂの長さが、図１中の（Ａ），（Ｂ）に示すように長短変化する。 Further, in the lattice plate structure of the present invention, when the angle formed by the two lattice plates 1 and 2 changes, in other words, as shown in FIG. 1, the tip 1b of one lattice plate 1 is shown. The vertical line Tb connected to the base end 1a, 2a where the two lattice plates 1, 2 are stacked is connected to the reference line Ta connecting the first lattice 2 and the tip 2b of the other lattice plate 2 at right angles. As shown in (A) and (B) in FIG.

さらに、本発明のラチス板構造にあっては、一のラチス板１が一側面１１をストッパ部２１に当接する状態（図３（Ａ）参照）から逆方向、すなわち、反時計方向に回動して他側面１２がストッパ部２１に当接する（図３（Ｃ）参照）までの間（図３（Ｂ）参照）の回動を自在にし、二つのラチス板１，２がなす角度をリニアに変化させ、また、上記した垂直線Ｔｂの長さをリニアに変化させる。 Furthermore, in the lattice plate structure of the present invention, one lattice plate 1 rotates in the reverse direction, that is, counterclockwise from the state in which one side surface 11 abuts against the stopper portion 21 (see FIG. 3A). Then, the rotation until the other side surface 12 comes into contact with the stopper portion 21 (see FIG. 3C) (see FIG. 3B) is freely made, and the angle formed by the two lattice plates 1 and 2 is linear. In addition, the length of the above-described vertical line Tb is linearly changed.

ところで、本発明のラチス板構造にあっては、図示するところでは、一方部材Ｐ１および他方部材Ｐ２への二つのラチス板１，２の連結に連結具Ｊを利用するので、以下に、この連結具Ｊについて説明する。 By the way, in the lattice plate structure of the present invention, as shown in the figure, the connection tool J is used to connect the two lattice plates 1 and 2 to the one member P1 and the other member P2. The tool J will be described.

図２に示すように、連結具Ｊは、一方部材Ｐ１あるいは他方部材Ｐ２を抱持する抱持部Ｊ１と、この抱持部Ｊ１に連設して積層する一のラチス板１と他のラチス板２の各基端部１ａ，２ａを積層した状態で連結させ、また、一のラチス板１の先端部１ｂを、あるいは、他のラチス板２の先端部２ｂを連結させる連結部Ｊ２とを備える。 As shown in FIG. 2, the connector J includes a holding portion J1 that holds one member P1 or the other member P2, one lattice plate 1 that is connected and stacked on the holding portion J1, and another lattice. The base ends 1a and 2a of the plate 2 are connected in a stacked state, and the leading end 1b of one lattice plate 1 or the connecting portion J2 for connecting the leading end 2b of another lattice plate 2 is connected. Prepare.

そして、この連結具Ｊにあっては、図示するところでは、連結部Ｊ２に一のラチス板１および他のラチス板２の各基端部１ａ，２ａおよび先端部１ｂ，２ｂを貫通するボルトＢを螺入させ、一のラチス板１および他のラチス板２の各基端部１ａ，２ａおよび先端部１ｂ，２ｂをピン結合させる。 In the connector J, as shown in the figure, a bolt B that penetrates the base end portions 1a and 2a and the tip end portions 1b and 2b of one lattice plate 1 and the other lattice plate 2 in the connection portion J2. Then, the base end portions 1a and 2a and the tip end portions 1b and 2b of one lattice plate 1 and the other lattice plate 2 are pin-coupled.

なお、二つのラチス板１，２の基端部１ａ，２ａおよび各ラチス板１，２の先端部１ｂ，２ｂを貫通するボルトＢは、連結部Ｊ２に螺入して、二つのラチス板１，２の基端部１ａ，２ａおよび各ラチス板１，２の先端部１ｂ，２ｂを連結部Ｊ２に定着するが、これに代えて、ボルトＢが連結部Ｊ２の背面に設けられるナットに螺入することで、二つのラチス板１，２の基端部１ａ，２ａおよび各ラチス板１，２の先端部１ｂ，２ｂを連結部Ｊ２に定着するとしても良い。 The bolts B that pass through the base end portions 1a and 2a of the two lattice plates 1 and 2 and the distal end portions 1b and 2b of the respective lattice plates 1 and 2 are screwed into the connecting portion J2, and the two lattice plates 1 , 2 and the leading end portions 1b, 2b of the lattice plates 1, 2 are fixed to the connecting portion J2, but instead, the bolt B is screwed onto a nut provided on the back surface of the connecting portion J2. By inserting, the base end portions 1a and 2a of the two lattice plates 1 and 2 and the front end portions 1b and 2b of the respective lattice plates 1 and 2 may be fixed to the connecting portion J2.

連結具Ｊが二つのラチス板１，２をボルトＢ利用でピン接合するから、二つのラチス板１，２を含めた部材の交換が可能になり、また、二つのラチス板１，２がピン接合部分、すなわち、接点を中心にして回動することが許容され、回動が許容されないことで、連結具Ｊを介して一方部材Ｐ１あるいは他方部材Ｐ２が変形するなどをあらかじめ防止できる。 Since the connector J pins the two lattice plates 1 and 2 using bolts B, it is possible to replace the members including the two lattice plates 1 and 2, and the two lattice plates 1 and 2 are connected to the pin. It is allowed to rotate about the joint portion, that is, the contact point, and the rotation is not allowed, so that it is possible to prevent the one member P1 or the other member P2 from being deformed via the connector J in advance.

次に、他のラチス板２に形成されるストッパ部２１についてだが、基本的には、Ｖ字状に組まれた二つのラチス板１，２にあって、一のラチス板１の他のラチス板２に対する徒な回動を阻止する限りには、自由な構成とされて良いが、図示するところでは、ストッパ部２１が他のラチス板２の裏面側からするこのラチス板２に対する加圧成形でこのラチス板２の上面に突出する態勢に形成される。 Next, regarding the stopper portion 21 formed on the other lattice plate 2, basically, there are two lattice plates 1, 2 assembled in a V-shape, and the other lattice of one lattice plate 1. As long as the automatic rotation with respect to the plate 2 is prevented, a free configuration may be adopted. However, in the illustrated case, the stopper portion 21 is pressure-formed on the lattice plate 2 from the back side of the other lattice plate 2. Thus, it is formed so as to protrude from the upper surface of the lattice plate 2.

すなわち、ストッパ部２１を他のラチス板２の上面に突出するように形成するために、たとえば、他部材を溶接などする場合には、他部材を要する他に溶接作業を要することになり、結果として、他のラチス板２の製品コストを高騰させる危惧があるが、加圧成形による場合には、他部材を要しないし、溶接作業を要しない上に、一つのプレス成形で素材からの裁断とストッパ部２１の形成が可能になる点で有利になる。 That is, in order to form the stopper portion 21 so as to protrude from the upper surface of the other lattice plate 2, for example, when welding other members, a welding operation is required in addition to the other members. As a result, there is a risk that the product cost of other lattice plates 2 will rise, but in the case of pressure forming, other members are not required, welding work is not required, and cutting from the material by one press forming This is advantageous in that the stopper portion 21 can be formed.

一方、他のラチス板２の上面に形成されるストッパ部２１の形態についてであるが、要は、図３に示すように、一のラチス板１が他のラチス板２に対して、たとえば、一方向たる時計方向に回動するときに、一のラチス板１の一側面１１を当接させる一当接部２２（図３（Ｂ），（Ｃ）参照）と、他方向たる反時計方向に回動するときに、一のラチス板１の他側面１２を当接させる他当接部２３（図３（Ａ），（Ｂ）参照）とを備えるものであれば良い。 On the other hand, regarding the form of the stopper portion 21 formed on the upper surface of the other lattice plate 2, the point is that, as shown in FIG. One abutting portion 22 (see FIGS. 3B and 3C) that abuts one side surface 11 of one lattice plate 1 when rotating clockwise in one direction, and counterclockwise in the other direction Any other contact portion 23 (see FIGS. 3A and 3B) for contacting the other side surface 12 of the one lattice plate 1 when it is rotated to the right side may be used.

以下に、ストッパ部２１の形態について、図４および図５の実施形態に基づいて、説明するが、図４（Ａ）に示す他のラチス板２は、図３に示す他のラチス板２である。 Below, the form of the stopper part 21 is demonstrated based on embodiment of FIG. 4 and FIG. 5, However, the other lattice board 2 shown to FIG. 4 (A) is the other lattice board 2 shown in FIG. is there.

そして、この図４（Ａ）に示すストッパ部２１は、一のラチス板１の一側面１１を当接させる（図３（Ａ）参照）一当接部２２と、一のラチス板１の他側面１２を当接させる（図３（Ｃ）参照）他当接部２３とを備える。 The stopper portion 21 shown in FIG. 4 (A) contacts one side surface 11 of one lattice plate 1 (see FIG. 3 (A)) and the other contact portion 22 of one lattice plate 1. Other contact portions 23 are provided for contacting the side surface 12 (see FIG. 3C).

このとき、先ず、図示する実施形態では、一当接部２２と他当接部２３とが一連に、すなわち、連続形成されるとし、次に、一当接部２２および他当接部２３が、図４（Ａ）中に二点鎖線ａ，ｂで示すように、線部（符示せず）を備えて、当接部２２，２３があることを目視で確認できるようにすると共に、一のラチス板１における側面１１，１２の安定した当接を可能にしている。 At this time, first, in the illustrated embodiment, it is assumed that the one contact portion 22 and the other contact portion 23 are formed in series, that is, continuously, and then the one contact portion 22 and the other contact portion 23 are formed. 4A, as shown by two-dot chain lines a and b, a line portion (not shown) is provided so that the contact portions 22 and 23 can be visually confirmed. This makes it possible to stably contact the side surfaces 11 and 12 of the lattice plate 1.

図４（Ｂ）に示す他のラチス板２にあっては、ストッパ部２１（図４（Ｂ）中に符示せず）が分離形成された二条のリブ２１ａ，２１ｂからなるとし、一のリブ２１ａの図４（Ｂ）中で右端となる先端を一のラチス板１の一側面１１が当接する一当接部２２とし、一のリブ２１ａの図４（Ｂ）中で右端部となる先端部の湾曲部（符示せず）が一のラチス板１の他側面１２が当接する他当接部２３ａにしている。 In the other lattice plate 2 shown in FIG. 4 (B), it is assumed that the stopper portion 21 (not shown in FIG. 4 (B)) is composed of two ribs 21a and 21b formed separately. 4A, the tip that is the right end in FIG. 4B is a contact portion 22 that contacts one side surface 11 of one lattice plate 1, and the tip that is the right end in FIG. 4B of one rib 21a. The curved portion (not shown) of the portion is the other contact portion 23a with which the other side surface 12 of the single lattice plate 1 contacts.

そして、この図４（Ｂ）に示す他のラチス板２にあっては、ストッパ部２１を構成する他のリブ２１ｂの図４（Ｂ）中で右端部となる先端部の湾曲部も一のラチス板１の他側面１２が当接する別の他当接部２３ｂにしている。 In the other lattice plate 2 shown in FIG. 4 (B), the curved portion of the tip portion which is the right end portion in FIG. 4 (B) of the other rib 21b constituting the stopper portion 21 is also the same. Another contact portion 23b with which the other side surface 12 of the lattice plate 1 abuts is used.

つまり、この図４（Ｂ）に示す実施形態の他のラチス板２にあっては、一のラチス板１の他側面１２が当接する他当接部２３（符示せず）が図４（Ｂ）中で左右方向に前後する二つの当接部２３ａ，２３ｂの離れた二か所からなるとし、この離れた二つの当接部２３ａ，２３ｂに一のラチス板１の他側面１２が安定して当接するとしている。 That is, in the other lattice plate 2 of the embodiment shown in FIG. 4B, the other contact portion 23 (not shown) with which the other side surface 12 of the one lattice plate 1 contacts is shown in FIG. ), The other side surface 12 of one lattice plate 1 is stabilized by the two separated contact portions 23a and 23b. To contact.

上記した図４（Ａ），図４（Ｂ）に示す実施形態にあっては、ストッパ部２１が他のラチス板２のほぼ全長に及ぶほどの大きさに形成されて、他のラチス板２における強度を大きくする、すなわち、補強するが、ストッパ部２１が一当接部２２および他当接部２３を備える限りには、これに代えて、必要最小限度の大きさに形成されても良い。 In the embodiment shown in FIGS. 4 (A) and 4 (B), the stopper portion 21 is formed to have a size that covers almost the entire length of the other lattice plate 2, and the other lattice plate 2. However, as long as the stopper portion 21 includes the one abutting portion 22 and the other abutting portion 23, the strength may be reduced to the minimum necessary size. .

図４（Ｃ）に示すところは、上記した実施形態に比較すると、ストッパ部２１が言わば一当接部２２と他当接部２３とを備えるだけの形態に形成され、この形態では、特に、一当接部２２が明確な線部（符示せず）を備えるとしている。 As shown in FIG. 4C, compared to the above-described embodiment, the stopper portion 21 is formed so as to include only one abutting portion 22 and the other abutting portion 23. In this embodiment, in particular, One contact portion 22 is provided with a clear line portion (not shown).

一方、図４（Ｃ）中に円で囲って図示するストッパ部２１にあっては、他当接部２３だけでなく、一当接部２２も明確な線部を備えず、言わば接線が当接する接点（符示せず）を設けるとするものである。 On the other hand, in the stopper portion 21 shown in a circle in FIG. 4C, not only the other abutting portion 23 but also the one abutting portion 22 does not have a clear line portion. A contact point (not shown) is provided.

上記の線部を備えるストッパ部２１および接点を備えるストッパ部２１にあっては、このストッパ部２１を他のラチス板２の裏側からする加圧成形で形成する場合には、前記した図４（Ａ）および図４（Ｂ）に示す言わば広域に亘るストッパ部２１を加圧成形で形成する場合に比較して、その作業を簡単にする利点がある。 In the stopper part 21 having the above-described line part and the stopper part 21 having a contact point, when the stopper part 21 is formed by pressure molding from the back side of another lattice plate 2, the above-described FIG. Compared with the case where the stopper portion 21 covering a wide area is formed by pressure molding as shown in A) and FIG. 4B, there is an advantage of simplifying the operation.

のみならず、この図４（Ｃ）に示すストッパ部２１にあっては、前記した図４（Ａ）および図４（Ｂ）に示すストッパ部２１に比較していわゆる点状に形成されるから、特に、平面視で円形に形成される場合には、加圧成形に代えて、溶けた金属による盛り上げや鋲の打設などで設けることも可能になる。 In addition, the stopper portion 21 shown in FIG. 4C is formed in a so-called dot shape as compared with the stopper portion 21 shown in FIGS. 4A and 4B. In particular, when it is formed in a circular shape in plan view, it can be provided by bulging with molten metal or placing a ridge instead of pressing.

ところで、他のラチス板２の上面に突出するストッパ部２１は、一のラチス板１の他のラチス板２に対する徒な回動を阻止することを目的に形成されるが、この観点からすれば、他のラチス板２の上面に形成されるストッパ部２１は、他のラチス板２の上面に隆起したり起立したりして突出すれば足りるので、上記の加圧成形に代えて、図５，図６および図７に示すように、打ち抜き成形や折り曲げ成形で形成されても良いことになる。 By the way, the stopper portion 21 protruding from the upper surface of the other lattice plate 2 is formed for the purpose of preventing an arbitrary rotation of the one lattice plate 1 with respect to the other lattice plate 2. The stopper portion 21 formed on the upper surface of the other lattice plate 2 only needs to be raised or raised on the upper surface of the other lattice plate 2 so that it protrudes. 6 and 7, it may be formed by punching or bending.

一方、ストッパ部２１が他のラチス板２の上面に突出する態勢についてであるが、裏面側からする加圧成形の場合には、ストッパ部２１における上端の外周縁を鋭角に形成するのは容易でなく、むしろ、図示しないが、傾斜面にしたりあるいは湾曲面にしたりして全体的に丸身を帯びるように形成するのが容易になる。 On the other hand, the stopper portion 21 is in a state of protruding from the upper surface of the other lattice plate 2, but in the case of pressure molding from the back surface side, it is easy to form the outer peripheral edge of the upper end of the stopper portion 21 at an acute angle. Rather, although not shown, it becomes easy to form an inclined surface or a curved surface so as to be rounded as a whole.

そして、ストッパ部２１の上端の外周縁が丸身を帯びるように形成される場合には、二つのラチス板１，２における基端部１ａ，２ａを積層して枢支する際に、いわゆる強く枢支する場合には、一のラチス板１がストッパ部２１を乗り越えて他のラチス板２に対して回動することを防止するが、いわゆる緩く枢支する場合には、一のラチス板１がストッパ部２１を乗り越えて他のラチス板２に対して回動することを許容することも可能になる。 When the outer peripheral edge of the upper end of the stopper portion 21 is formed to be round, when the base end portions 1a and 2a of the two lattice plates 1 and 2 are stacked and pivotally supported, so-called strong In the case of pivoting, one lattice plate 1 is prevented from overturning the other lattice plate 2 over the stopper portion 21, but in the case of so-called loose pivoting, one lattice plate 1 is prevented. It is also possible to allow it to turn over the other lattice plate 2 over the stopper portion 21.

このことは、二つのラチス板１，２をＶ字状に仮固定状態にする際の操作性を良くすることに繋がると言える。すなわち、前記した図３に示すところでは、図３（Ａ）に示す９０度のＶ字状から図３（Ｃ）に示す９０度未満のＶ字状に移行する際には、一のラチス板１を反時計方向に大きく回動することを要すとしている。 This can be said to improve the operability when the two lattice plates 1 and 2 are temporarily fixed in a V shape. That is, in the case shown in FIG. 3 described above, when shifting from the 90-degree V-shape shown in FIG. 3A to the less-90-degree V-shape shown in FIG. 1 is required to be largely rotated counterclockwise.

これに対して、ストッパ部２１が一のラチス板１の乗り越えを許容する態勢にある場合には、図３（Ａ）に示す態勢から一のラチス板１を時計方向に僅かに回動すれば足りることになり、この限りにおいて、二つのラチス板１，２をＶ字状に仮固定状態にする際の操作性を良くすることになる。 On the other hand, when the stopper portion 21 is in a posture to allow the lattice plate 1 to get over, if one lattice plate 1 is slightly rotated clockwise from the posture shown in FIG. As long as this is sufficient, the operability when the two lattice plates 1 and 2 are temporarily fixed in a V shape is improved.

戻って、図５，図６および図７に示すところは、ストッパ部２１が打ち抜き成形されたり折り曲げ成形されたりして形成される場合を示すが、この場合には、ストッパ部２１の他のラチス板２の上面から突出する高さが大きくなり易いので、前記したような、一のラチス板１のストッパ部２１の乗り越え現象が発現され難くなる。 5, 6 and 7 show the case where the stopper portion 21 is formed by stamping or bending, and in this case, other lattices of the stopper portion 21 are shown. Since the height protruding from the upper surface of the plate 2 tends to be large, the phenomenon of overcoming the stopper portion 21 of the one lattice plate 1 as described above is hardly exhibited.

すなわち、図５および図６に示す他のラチス板２にあっては、ストッパ部２１が他のラチス板２の裏面側からする打ち抜き成形で形成され、図７に示す他のラチス板２にあっては、ストッパ部２１が他のラチス板２の裏面側からする折り曲げ成形で形成される。 That is, in the other lattice plate 2 shown in FIGS. 5 and 6, the stopper portion 21 is formed by punching from the back side of the other lattice plate 2, and the other lattice plate 2 shown in FIG. Thus, the stopper portion 21 is formed by bending from the back side of the other lattice plate 2.

そして、この図５，図６および図７に示す実施形態にあっても、前記した図４に示す実施形態の場合と同様に、図示しない一のラチス板１の一側面１１（図３参照）を当接させる一当接部２２と、一のラチス板１の他側面１２（図３参照）を当接させる他当接部２３とを備える。 In the embodiment shown in FIGS. 5, 6 and 7, as in the case of the embodiment shown in FIG. 4, one side surface 11 (see FIG. 3) of one lattice plate 1 not shown. One abutting portion 22 that abuts the other side surface 12 (see FIG. 3) of one lattice plate 1.

また、図５に示す実施形態では、一当接部２２が線部（符示せず）を備えて、一のラチス板１の一側面１１が当接する部位を明確に視認できるようにし、図６および図７に示す実施形態では、一当接部２２が図５に示す一当接部２２に比較すると短くなるが、それでも線部を備えて、一のラチス板１の一側面１１が当接する部位を視認し得るようにしている。 Further, in the embodiment shown in FIG. 5, the one abutting portion 22 includes a line portion (not shown) so that a portion where one side surface 11 of the one lattice plate 1 abuts can be clearly seen. In the embodiment shown in FIG. 7, the one abutting portion 22 is shorter than the one abutting portion 22 shown in FIG. 5, but still has a line portion and the one side surface 11 of one lattice plate 1 abuts. The site is visible.

図８に示す他のラチス板２にあって、ストッパ部２１は、言わば本体部（符示せず）に対する加圧成形で本体部に段差部（符示せず）を設け、この段差部が一当接部２２を備えると共に他当接部２３を備えるとする。 In the other lattice plate 2 shown in FIG. 8, the stopper portion 21 is provided with a step portion (not shown) in the main body portion by press molding to the main body portion (not shown), and this step portion is applied to the stopper portion 21. It is assumed that the contact portion 22 and the other contact portion 23 are provided.

なお、この図８に示す実施形態にあっても、図示しない一のラチス板１については、前記した各実施形態の場合と同様に、言わば単純な平板状に形成されたラチス板１（図２および図３参照）が利用されるとしても良く、また、各実施形態の他のラチス板２（図４，図５，図６参照）が利用されるとしても良い。 In the embodiment shown in FIG. 8, the lattice plate 1 (not shown) is, as in the case of the above-described embodiments, the lattice plate 1 formed in a simple flat plate shape (FIG. 2). 3 may be used, and another lattice plate 2 (see FIGS. 4, 5, and 6) of each embodiment may be used.

以上のように、本発明のラチス板構造にあっては、相対向して一対となる一方部材Ｐ１と他方部材Ｐ２とをＶ字状に組んだ二つのラチス板１，２を利用して連結するとき、一のラチス板１を他のラチス板２に対して一方向、たとえば、時計方向に回動するとき、二つのラチス板１，２のなす角度を大きく、たとえば、９０度にして、二つのラチス板１，２が表出する垂直線Ｔｂの長さを小さくでき、反対に、一のラチス板１を他のラチス板２に対して他方向、たとえば、反時計方向に回動するとき、二つのラチス板１，２のなす角度を小さく、たとえば、９０度未満にして、二つのラチス板１，２が表出する垂直線Ｔｂの長さを大きくできる。 As described above, in the lattice plate structure according to the present invention, the two lattice plates 1 and 2 in which the paired one member P1 and the other member P2 are combined in a V shape are connected to each other. When one lattice plate 1 is rotated in one direction, for example, clockwise, with respect to the other lattice plate 2, the angle formed by the two lattice plates 1 and 2 is increased to, for example, 90 degrees. The length of the vertical line Tb that the two lattice plates 1 and 2 appear can be reduced, and conversely, one lattice plate 1 is rotated with respect to the other lattice plate 2 in the other direction, for example, counterclockwise. When the angle formed by the two lattice plates 1 and 2 is small, for example, less than 90 degrees, the length of the vertical line Tb where the two lattice plates 1 and 2 are exposed can be increased.

そして、本発明のラチス板構造にあっては、一のラチス板１が一側面１１をストッパ部２１に当接する状態から逆方向、すなわち、反時計方向に回動して他側面１２がストッパ部２１に当接するまでの間の回動を自在にし、二つのラチス板１，２がなす角度をリニアに変化させ、また、上記の垂直線Ｔｂの長さをリニアに変化させることになる。 In the lattice plate structure of the present invention, one lattice plate 1 rotates in the reverse direction, that is, counterclockwise from the state in which one side surface 11 abuts against the stopper portion 21, and the other side surface 12 has the stopper portion. The angle between the two lattice plates 1 and 2 is changed linearly, and the length of the vertical line Tb is changed linearly.

その結果、本発明のラチス板構造によれば、既設の一方部材Ｐ１に新たに他方部材Ｐ２を対向させて両部材Ｐ１，Ｐ２をラチス板１，２で連結する際に、両部材Ｐ１，Ｐ２間の間隔が一定にならずして区々になる場合にも、両部材Ｐ１，Ｐ２をＶ字状に組んだ二つのラチス板１，２の連結でトラス体にすることが可能になる。 As a result, according to the lattice plate structure of the present invention, when the other member P2 is newly opposed to the existing one member P1 and the members P1 and P2 are connected by the lattice plates 1 and 2, both members P1 and P2 are used. Even when the distance between them is not constant, the truss body can be formed by connecting two lattice plates 1 and 2 in which both members P1 and P2 are assembled in a V shape.

また、本発明のラチス板構造によれば、一方部材Ｐ１と他方部材Ｐ２とをＶ字状に組んだ二つラチス板１，２で連結する際に、二つのラチス板１，２を広狭いずれかの角度のＶ字状に仮固定状態にすることが可能になり、二つのラチス板１，２がＶ字状に仮固定されない状態にある、すなわち、一のラチス板１が他のラチス板２に対して自由に回動して仮固定状態を具現化できない場合に比較して、二つのラチス板１，２で両部材Ｐ１，Ｐ２を連結してトラス体にする際の作業性を向上させる。 Further, according to the lattice plate structure of the present invention, when the one member P1 and the other member P2 are connected by the two lattice plates 1 and 2 assembled in a V shape, the two lattice plates 1 and 2 are either wide or narrow. It is possible to temporarily fix the two lattice plates 1 and 2 in a V-shape at a certain angle, and the two lattice plates 1 and 2 are not temporarily fixed to the V-shape. That is, one lattice plate 1 is another lattice plate. Compared with the case where the temporarily fixed state cannot be realized by freely rotating with respect to 2, the workability when the two members P1 and P2 are connected by the two lattice plates 1 and 2 to form the truss body is improved. Let

そして、本発明のラチス板構造によれば、他のラチス板２に設けられるストッパ部２１は、他のラチス板２を裏側からする加圧成形や打ち抜き成形あるいは折り曲げ成形で形成し得るので、この種のストッパ部２１を設けるのにあって、他部材を利用したり、他部材を溶接したりする場合に比較して、ストッパ部２１の形成作業を容易にする。 And, according to the lattice plate structure of the present invention, the stopper portion 21 provided on the other lattice plate 2 can be formed by pressure molding, punching molding or bending molding of the other lattice plate 2 from the back side. In providing the kind of stopper portion 21, the operation of forming the stopper portion 21 is facilitated as compared with the case where other members are used or other members are welded.

そしてまた、本発明のラチス板構造によれば、ストッパ部２１は、他のラチス板２に設けられるので、一のラチス板１にあっては、ストッパ部２１を設けない平板状に形成されることで足り、二つのラチス板１，２を同じ態様に形成する場合に比較して、経済的に有利になる。 In addition, according to the lattice plate structure of the present invention, the stopper portion 21 is provided on the other lattice plate 2, and therefore, in the one lattice plate 1, it is formed in a flat plate shape without the stopper portion 21. Therefore, it is economically advantageous as compared with the case where the two lattice plates 1 and 2 are formed in the same manner.

前記したところでは、二つのラチス板１，２は、基端部１ａ，２ａと先端部１ｂ，２ｂとを結ぶ軸線方向の長さを同一にするが、一方部材Ｐ１と他方部材Ｐ２とに連結してトラス体を形成することからすれば、たとえば、一のラチス板１の長さが他のラチス板２の長さより短くなるとしても良く、この場合には、たとえば、一のラチス板１の先端部１ｂを連結する他方部材Ｐ２の部位に障害物があるなどするために連結を実践できない場合に、一のラチス板１の先端部１ｂを他方部材Ｐ２の別の部位に連結することが可能になるなどの利点を生む。 As described above, the two lattice plates 1 and 2 have the same axial length connecting the base end portions 1a and 2a and the tip end portions 1b and 2b, but are connected to one member P1 and the other member P2. Then, from the viewpoint of forming the truss body, for example, the length of one lattice plate 1 may be shorter than the length of another lattice plate 2. In this case, for example, the length of one lattice plate 1 When the connection cannot be practiced because there is an obstacle at the other member P2 that connects the tip 1b, the tip 1b of one lattice plate 1 can be connected to another portion of the other member P2. Produces benefits such as becoming.

そして、前記したところでは、一のラチス板１は、いわゆる平板状に形成されるとして説明したが、これに代えて、ストッパ部２１を備える他のラチス板２と同一のものが利用されても良く、この場合には、他のラチス板２の場合と同様に、一のラチス板１における強度を大きくする、すなわち、補強を可能にする点で有利になると共に、一のラチス板１における上面に意匠を施すことになり、一のラチス板１における美観を向上させる点でも有利になる。 In the above description, one lattice plate 1 has been described as being formed in a so-called flat plate shape, but instead of this, the same lattice plate 2 provided with the stopper portion 21 may be used. In this case, as in the case of the other lattice plate 2, it is advantageous in that the strength of the one lattice plate 1 is increased, that is, it is possible to reinforce, and the upper surface of the one lattice plate 1. This is advantageous in that the appearance of the lattice board 1 is improved.

以上で、本発明のラチス板構造についての説明を終了するが、前記した構成は一例であって、本発明のラチス板構造を具現化するのにあって、その構成が上記した構成に限定されないことはもちろんである。 This is the end of the description of the lattice plate structure of the present invention. However, the above-described configuration is an example, and the lattice plate structure of the present invention is embodied, and the configuration is not limited to the above-described configuration.
