Description

本発明は、体育館などの屋根架構に用いられる立体トラスの接合部構造に関し、全体が曲面や多面体などの任意曲面の立体トラス架構を構成する場合において、各節点部が板材により形成されるトラス部材の接合を従来よりも容易に行うことができる。   The present invention relates to a joint structure of a solid truss used for a roof frame such as a gymnasium, and a truss member in which each node portion is formed of a plate material when the whole forms a solid truss frame of an arbitrary curved surface such as a curved surface or a polyhedron. Can be more easily performed than in the past.

構造が立体トラスで、例えば図１に図示するように上弦材１の軸方向と下弦材２の軸方向が概ね平行な架構、あるいは図２に図示するように上弦材１の軸方向と下弦材２の軸方向が概ね４５度交差する架構において、全体が曲面や多面体などの任意形状である場合、上弦材１、下弦材２および上弦材１と下弦材２とを繋ぐラチス材３は任意の角度で上弦節点ａあるいは下弦節点ｂに集まるため、各節点の接合部を板材で製作すると各板材同士の接合がきわめて複雑なものになる。   The structure is a three-dimensional truss, for example, a frame in which the axial direction of the upper chord member 1 and the axial direction of the lower chord member 2 are substantially parallel as shown in FIG. 1, or the axial direction of the upper chord member 1 and the lower chord member as shown in FIG. In the frame in which the axial directions of 2 intersect approximately 45 degrees, if the whole is an arbitrary shape such as a curved surface or a polyhedron, the upper chord material 1, the lower chord material 2, and the lattice material 3 that connects the upper chord material 1 and the lower chord material 2 are arbitrary. Since they gather at the upper chord node a or the lower chord node b at an angle, if the joint portion of each node is made of a plate material, the joining of the plate materials becomes extremely complicated.

そこで従来、それを避けるためにラチス材などの部材を捩じる、あるいは接合部の板材を曲げるなどの処置を施していたが、設計や製作に多くの時間と労力を費やすことが多かった。   Conventionally, in order to avoid this, treatments such as twisting a member such as a lattice material or bending a plate material of a joint portion have been performed, but much time and labor are often spent on design and production.

例えば、図１１(ａ)，(ｂ)に図示する従来の立体トラスの例で説明すると、同図は、上弦材１と下弦材２の関係が図２に図示する立体トラス架構の一部分を示したものであり、図１１(ａ)は平面図、図１１(ｂ)は図１１(ａ)のホ−ホ線断面図である。   For example, in the case of the conventional three-dimensional truss shown in FIGS. 11A and 11B, the relationship between the upper chord member 1 and the lower chord member 2 shows a part of the three-dimensional truss frame shown in FIG. 11 (a) is a plan view, and FIG. 11 (b) is a sectional view taken along the line of FIG. 11 (a).

即ち、複数の上弦材１が構成する上弦面が直交格子、複数の下弦材２が構成する下弦面が平面視で概ね４５度交差する斜交格子であり、下弦節点ｂは４本の上弦材１で囲まれた平面視で四角形の中央下面に位置し、上弦節点ａと下弦節点ｂとを結ぶラチス材３は平面視で下弦材２の直上にあり、上弦面は平面、下弦面は下弦節点ｂを通る屋根版折り曲げ線ヘ−ヘにより１方向に折り曲げられた場合を示している。   That is, the upper chord surface formed by the plurality of upper chord members 1 is an orthogonal lattice, the lower chord surface formed by the plurality of lower chord members 2 is an oblique lattice that intersects approximately 45 degrees in plan view, and the lower chord node b is four upper chord members. The lattice material 3 connecting the upper chord node a and the lower chord node b is located immediately above the lower chord material 2 in plan view, the upper chord surface is flat and the lower chord surface is lower chord. The case where it is bent in one direction by the roof slab folding line passing through the node b is shown.

図１１(ｂ)から分るように、下弦面が折れ曲がっているために、上弦節点ａの十字プレート４と下弦節点ｂの十字プレート５の向きがそれぞれ違う方向を向いているので、ラチス材３(図では２本のＬ形鋼材)の軸線が上下弦節点ａ、ｂに一致するように取り付けるには、図示するように上弦節点ａのガセットプレート６と下弦節点ｂの十字プレート５のそれぞれの面と、ラチス材３のＬ形鋼両端部との接触面に肌すきが生じないように、ラチス材３のＬ形鋼を捩じって接合する必要があり、立体トラスの製作を難しいものにしていた。下弦材２についても同様であった。   As can be seen from FIG. 11 (b), since the lower chord surface is bent, the cross plate 4 at the upper chord node a and the cross plate 5 at the lower chord node b are directed in different directions. In order to attach the axes of the two (L-shaped steel members in the figure) so as to coincide with the upper and lower chord nodes a and b, the gusset plate 6 at the upper chord node a and the cross plate 5 at the lower chord node b as shown in the figure. It is necessary to twist and join the L-shaped steel of the lattice material 3 so that the surface of the contact surface between the L-shaped steel 3 and both ends of the L-shaped steel of the lattice material 3 does not become scratched, making it difficult to manufacture a solid truss I was doing. The same applies to the lower chord material 2.

また、ラチス材３を捩じらない方法として、上弦節点ａのガセットプレート６と下弦節点ｂの十字プレート５のそれぞれの面を、ラチス材３のＬ形鋼両端部との接触面に合うように折り曲げることでも接合は可能であるが、屋根版を二方向に折り曲げる(曲率を持つ)場合には、さらに複雑な接合部の納まりとなり、製作手間と製作コストだけでなく外観も悪くなるという問題もあった。   Further, as a method of not twisting the lattice material 3, the respective surfaces of the gusset plate 6 of the upper chord node a and the cross plate 5 of the lower chord node b are matched with the contact surfaces of both ends of the L-shaped steel of the lattice material 3. It is possible to join by bending the roof plate, but when the roof slab is bent in two directions (with curvature), it becomes a more complicated joint housing, and not only the labor and cost of production but also the appearance deteriorates. There was also.

上記問題を解決した従来方法として、接合部に球体や円柱を設け、各部材の端部を溶接する、あるいは部材端に特殊金物を設けた鋼管を用いて球体と１本ボルトで接合することで、無理なく各部材の軸線を一点に引き付ける方法、あるいは、接合部を板材で製作するが、各部材の軸線を一点に引き付けるのではなく若干偏心させることで、部材を捩じる、あるいはガセットプレートを曲げる等しなくてもよい方法が用いられていた。   As a conventional method for solving the above problem, a sphere or a cylinder is provided at the joint, and the end of each member is welded, or a steel pipe with a special hardware provided at the end of the member is used to join the sphere with one bolt. A method of pulling the axis of each member to one point without difficulty, or manufacturing the joint with a plate, but twisting the member by slightly decentering rather than pulling the axis of each member to one point, or a gusset plate A method that does not require bending is used.

しかし、接合部に球体を用いる方法は、特殊金物とねじ切り等の機械加工が必要であること、円柱を用いる方法は、ガセットプレートとの溶接線が曲線となるため、精度確保等製作手間がかかる等の理由からコストが高くなり、また、部材軸線の引き付けを偏心させる方法は、偏心による局部曲げが発生し、別途処理が必要になるという面倒さがあった。本発明に関連する先行技術文献としては、例えば特許文献１〜３が提示されている。   However, the method of using a sphere for the joint requires machining such as special hardware and thread cutting, and the method of using a cylinder requires a lot of manufacturing work such as ensuring accuracy because the welding line with the gusset plate is curved. For this reason, the cost is high, and the method for decentering the member axis is troublesome in that local bending occurs due to the decentration and a separate process is required. As prior art documents related to the present invention, for example, Patent Documents 1 to 3 are presented.

特公昭45-33572「版状立体トラスの各接点の接合方法」JP-B 45-33572 "Joint method of each contact point of plate-shaped solid truss" 実公昭53-28967「立体トラスに於ける仕口構造」Shoko Sho 53-28967 "Seal structure in three-dimensional truss" 特許第3537771号「立体トラスの接合部構造」Patent No.3537771 “Construction structure of three-dimensional truss”

文献１および２における立体トラスの接合方法は、上弦節点と下弦節点とを繋ぐラチス材の両端部を板材にて接合するものであるが、立体トラスの形状が概ね平版に限られるものであり、例えばドーム等のように曲面の場合では、部材を捩じるあるいは板材を曲げる、あるいは各部材の軸線を一点に引き付けるのではなく、若干偏心させる等の従来方法が必要になるという課題があった。   The joining method of the solid truss in Documents 1 and 2 is to join both ends of the lattice material connecting the upper chord node and the lower chord node with a plate material, but the shape of the solid truss is generally limited to a flat plate, For example, in the case of a curved surface such as a dome, there is a problem that a conventional method such as slightly eccentricity is required instead of twisting a member, bending a plate material, or attracting the axis of each member to one point. .

また、特許文献３における立体トラスの接合方法は、上弦材の軸方向と下弦材の軸方向が概ね平行な架構について、上弦節点と下弦節点において平面視で概ね直交に交差配置される一対の接合金物と、一対の略山形状のガセットプレート頂部にほぞ溝を刻設したものから構成され、それら一対のガセットプレートが対向するようにほぞ溝を接合金物に挿入したものである。   In addition, the joining method of the three-dimensional truss in Patent Document 3 is a pair of joints arranged so that the upper chord joint and the lower chord joint are substantially orthogonally crossed in plan view at the upper chord node and the lower chord joint on a frame in which the axial direction of the upper chord member and the axial direction of the lower chord member are substantially parallel. It is composed of a hardware and a mortise groove formed on the top of a pair of substantially mountain-shaped gusset plates, and the mortise grooves are inserted into the joining hardware so that the pair of gusset plates face each other.

従って、ラチス材端部と接合される略山形状のガセットプレートの角度を変更することにより、平版だけでなく、例えば一方向に曲率を有する円筒形などの屋根版を形成することも可能である。   Therefore, by changing the angle of the substantially mountain-shaped gusset plate joined to the end of the lattice material, it is possible to form not only a flat plate but also a roof plate such as a cylindrical shape having a curvature in one direction. .

しかし、図１および図２に図示するようにドーム等の二方向に曲率を持つ形状に対しては、やはり特許文献１ないし２と同様、適用は難しい。   However, as shown in FIGS. 1 and 2, it is difficult to apply to a shape having a curvature in two directions such as a dome as in Patent Documents 1 and 2.

本発明は、以上の課題を解決するためになされたもので、全体が曲面や多面体などの任意曲面の立体トラス架構を構成する場合でも、各節点部におけるトラス部材の接合を容易に行うことのできる立体トラスの接合部構造を提供することを目的とする。   The present invention has been made to solve the above-described problems, and even when a three-dimensional truss frame having an arbitrary curved surface such as a curved surface or a polyhedron is configured as a whole, it is possible to easily join the truss members at each node portion. An object of the present invention is to provide a joint structure for a three-dimensional truss.

請求項１記載の立体トラスの接合部構造は、平面視において直交格子とした上弦材と、当該直交格子の網目中央下面に節点が位置しかつ部材軸方向が前記上弦材に対して概ね４５度交差する斜交格子とした下弦材と、前記上弦材の上弦節点と前記下弦材の下弦節点間に配置された複数のラチス材、および前記上弦節点と前記下弦節点にそれぞれ配置された複数の節点継手金物とを備えてなる立体トラスの接合部構造において、前記節点継手金物は前記下弦材およびラチス材の端部に対向し、かつ隣り合う二側面部からなる入り隅部を備え、前記下弦材およびラチス材の端部は前記入り隅部の隣り合う二側面部にそれぞれのガセットプレートを介して接合されてなることを特徴とするものである。   The joint structure of the three-dimensional truss according to claim 1 includes an upper chord material having an orthogonal lattice in plan view, a node located on the lower surface of the center of the mesh of the orthogonal lattice, and a member axial direction of approximately 45 degrees with respect to the upper chord material. A lower chord material that intersects an oblique grid, a plurality of lattice materials arranged between the upper chord node of the upper chord material and the lower chord node of the lower chord material, and a plurality of nodes respectively arranged at the upper chord node and the lower chord node In the joint structure of a three-dimensional truss comprising a joint hardware, the node joint hardware is provided with a corner portion composed of two adjacent side surfaces facing the lower chord material and the end of the lattice material, and the lower chord material And the edge part of a lattice material is joined to the two adjacent side surface parts of the said entrance corner part via each gusset plate, It is characterized by the above-mentioned.

本発明は、立体トラス架構の各節点における上弦材、下弦材およびラチス材の端部を互いに節点継手金物を介して接合することにより、特に下弦材とラチス材の端部は、節点継手金物に形成された入り隅部の隣り合う二側面部にガセットプレートを介して接合することにより下弦材とラチス材の接合を容易に行えるようにしたものである。   In the present invention, the ends of the upper chord member, the lower chord member, and the lattice member at each node of the three-dimensional truss frame are joined to each other via a joint joint metal, and particularly, the end portions of the lower chord member and the lattice member are joined to the joint joint hardware. The lower chord material and the lattice material can be easily joined to each other by joining the two adjacent side surfaces of the formed corner portion via a gusset plate.

本発明によれば、各節点に集まる下弦材とラチス材の軸方向に合せて、ガセットプレートの向きを自由に設定することが可能なことにより、従来、接合部の納まりが難しかった曲面や多面体などの任意形状の立体トラス架構を容易かつ安価に製作することができる。   According to the present invention, it is possible to freely set the orientation of the gusset plate in accordance with the axial direction of the lower chord material and the lattice material gathered at each node, so that a curved surface or polyhedron that has conventionally been difficult to fit the joint portion It is possible to easily and inexpensively manufacture a three-dimensional truss frame of any shape such as.

また、採用されることの多い平版、山形あるいは一方向のみに曲率を持つ円筒形などの立体トラス架構の場合には、接合部の形状がより単純になり、立体トラス架構をより廉価に製作することができる。   In addition, in the case of a three-dimensional truss frame such as a flat plate, a mountain shape, or a cylindrical shape that has a curvature only in one direction, the shape of the joint becomes simpler and the three-dimensional truss frame can be manufactured at a lower cost. be able to.

節点継手金物は、節点部に集まる上弦材、下弦材およびラチス材の数量や向きに合せて、プレートや鋳造により容易に形成することができる。   The joint metal fitting can be easily formed by plate or casting according to the quantity and orientation of the upper chord material, the lower chord material and the lattice material gathered at the node portion.

請求項２記載の立体トラスの接合部構造は、平面視において直交格子とした下弦材と、当該直交格子の網目中央上面に節点が位置しかつ部材軸方向が前記下弦材に対して概ね４５度交差する斜交格子とした上弦材と、前記下弦材の下弦節点と前記上弦材の上弦節点間に配置された複数のラチス材、および前記下弦節点と前記上弦節点にそれぞれ配置された複数の節点継手金物とを備えてなる立体トラスの接合部構造において、前記節点継手金物は前記上弦材およびラチス材の端部に対向し、かつ隣り合う二側面部からなる入り隅部を有し、前記上弦材およびラチス材の端部は前記入り隅部の隣り合う二側面部にそれぞれのガセットプレートを介して接合されてなることを特徴とするものである。   The joint structure of the three-dimensional truss according to claim 2 includes a lower chord material having an orthogonal lattice in a plan view, a node located on the center upper surface of the mesh of the orthogonal lattice, and a member axial direction of approximately 45 degrees with respect to the lower chord material. An upper chord material that intersects a diagonal grid, a plurality of lattice materials arranged between the lower chord node of the lower chord material and the upper chord node of the upper chord material, and a plurality of nodes respectively arranged at the lower chord node and the upper chord node In the joint structure of a three-dimensional truss comprising a joint hardware, the node joint hardware has an entering corner portion formed by two adjacent side surfaces facing the upper chord material and the end of the lattice material, and the upper chord The end portions of the material and the lattice material are joined to two adjacent side surface portions of the entering corner portion via respective gusset plates.

本発明は、請求項１記載の立体トラスの接合部構造において、上弦面と下弦面の格子形状が入れ替わっただけであり、課題解決の手段・効果としては、請求項１と全く同じである。   According to the present invention, in the joint structure of the three-dimensional truss according to the first aspect, only the lattice shapes of the upper chord surface and the lower chord surface are interchanged.

請求項３記載の立体トラスの接合部構造は、請求項１ないし２記載の立体トラスの接合部構造において、節点継手金物は複数のコアプレートから形成されてなることを特徴とするものである。   The joint structure of the three-dimensional truss according to claim 3 is the joint structure of the three-dimensional truss according to claim 1 or 2, characterized in that the node joint metal fitting is formed from a plurality of core plates.

節点継手金物は、例えば、四枚のコアプレートを平面視ほぼ十字型に突合せ、かつ互いを溶接等で結合することにより容易に製作することができる。また特に、屋根周縁部の節点部に設置される節点継手金物は、三枚のコアプレートを平面視ほぼＴ字型に突合せ、かつ互いを溶接等で結合することにより形成することができ、さらに屋根のコーナ部に設置される節点継手金物は、二枚のコアプレートを平面視ほぼＬ字型に突合せ、かつ互いを溶接等で結合することにより容易に製作することができる。   The node joint hardware can be easily manufactured by, for example, butting four core plates in a substantially cross shape in plan view and joining them together by welding or the like. Further, in particular, the joint metal fittings installed at the joints on the peripheral edge of the roof can be formed by butting three core plates in a substantially T shape in plan view and joining each other by welding or the like. The joints for joints installed at the corners of the roof can be easily manufactured by butting two core plates in a substantially L shape in plan view and joining them together by welding or the like.

そして、いずれのタイプも、隣り合う二枚のコアプレートからなる入り隅部にガセットプレートを配置し、かつ隣り合う二枚のコアプレートに溶接等により取り付けるだけでよい。   In both types, a gusset plate is disposed at the corner of the two core plates adjacent to each other and attached to the two adjacent core plates by welding or the like.

また、ガセットプレートは、工場などで節点継手金物を製作する際に、金物の一部として予め取り付けておき、現場ではラチス材などの接合を接合ボルトのみで行うようにすれば、現場作業を効率的に行うことができる。   In addition, the gusset plate can be installed in advance as part of the hardware when manufacturing joints for joints at a factory, etc., and on-site work can be performed efficiently using only joint bolts such as lattice materials. Can be done automatically.

請求項４記載の立体トラスの接合部構造は、請求項１ないし３記載の立体トラスの接合部構造において、ガセットプレートは、節点部に集まる複数の下弦材または上弦材が接合される共有のガセットプレートとして突設されてなることを特徴とするものである。   The joint structure of the three-dimensional truss according to claim 4 is the joint structure of the three-dimensional truss according to any one of claims 1 to 3, wherein the gusset plate is a shared gusset to which a plurality of lower chord members or upper chord members gathered at the node portions are joined. It is characterized by projecting as a plate.

本発明によれば、ガセットプレートの数量と溶接個所が少なく、容易に製作できる等のメリットがある。   According to the present invention, there are merits that the number of gusset plates and the number of welded portions are small and the gusset plates can be easily manufactured.

(1) 任意曲面を有する立体トラス架構を形鋼で構成する場合でも、本発明による節点継手金物を用いるトラス接合部の納め方によれば、ガセットプレートの傾きと形状で調整することができるので、部材軸線の引き付け点を偏心させる必要がなく、また部材を捩るあるいは接合部の板材を曲げる必要もなくなるので、節点継手金物を板材で構成しても、設計、製作が容易である。   (1) Even when a three-dimensional truss frame with an arbitrary curved surface is made of steel, it can be adjusted by the inclination and shape of the gusset plate according to the way of storing the truss joint using the joints of joints according to the present invention. In addition, since it is not necessary to decenter the attracting point of the member axis, and it is not necessary to twist the member or bend the plate material of the joint portion, the design and manufacture are easy even if the joint material of the joint is made of a plate material.

(2) 通常、よく採用される網目割(上弦面、下弦面共に直交格子)の屋根版(図１参照)において、経済性を考慮して部材数を減らすために格子寸法を大きくすることがあるが、そうすると上弦材の座屈長が長くなり、また上弦材に沿って設ける母屋受け材などの支点(上弦節点)間距離が長くなるという欠点があった。   (2) Normally, in the roof plate (see Fig. 1) of the mesh division that is often used (both upper and lower chord planes are orthogonal grids), the grid dimensions can be increased to reduce the number of members in consideration of economy. However, there is a drawback that the buckling length of the upper chord material becomes longer and the distance between the fulcrum (upper chord node) of the purlin support material provided along the upper chord material becomes longer.

即ち、上弦材および母屋受け材などのサイズが大きくなるが、本発明が対象とする図２に図示するタイプの立体トラス構造によれば、平面視において、上弦(直交格子)の網目は、下弦(斜交格子)の網目に対して概ね４５度回転して内接する形になるため、上弦面の網目一辺の長さは下弦面の７０％程度となる。   That is, although the size of the upper chord material and the purlin support material is increased, according to the three-dimensional truss structure of the type shown in FIG. 2 targeted by the present invention, the mesh of the upper chord (orthogonal lattice) is lower in the plan view. Since it is inscribed by rotating approximately 45 degrees with respect to the mesh of the (oblique grid), the length of one side of the mesh of the upper chord surface is about 70% of the lower chord surface.

即ち、下弦材は長くなるが、上弦材は座屈長が短いので細い部材でも圧縮耐力を確保でき、また母屋受け材などの支点(上弦節点)間距離も短いので、上弦材および母屋受け材などのサイズは通常の網目割を大網目にした場合よりも小さくてすむ。また、下弦材とラチス材の本数が前記通常網目割よりも少なくて済む。   In other words, the lower chord material becomes longer, but the upper chord material has a short buckling length, so that even a thin member can secure compression strength, and the distance between the fulcrum (upper chord node) of the purlin support material is also short. The size of etc. can be smaller than the case where the normal mesh is divided into large meshes. In addition, the number of lower chord materials and lattice materials can be smaller than the above normal mesh division.

これらのことは、材料の効率的使用の観点から、特に多雪地域や重い仕上げ材(コンクリート等)を葺く場合に有利であるが、このようなタイプの立体トラス架構について、従来、接合部の納まりが難しかった任意形状の場合であっても、本発明によれば、容易かつ安価に製作することに対して大いに貢献する。   These are advantageous from the viewpoint of efficient use of materials, especially when snowy areas and heavy finishing materials (concrete etc.) are used. Even in the case of an arbitrary shape that is difficult to fit, according to the present invention, it greatly contributes to easy and inexpensive manufacturing.
