Description
本発明は、アンモニアガスの発生が多い畜舎・堆肥醗酵舎などの建物に有効な木造トラス建物に関する。 The present invention relates to a wooden truss building that is effective for buildings such as livestock barns and composting fertilizer houses that generate a lot of ammonia gas.
畜舎・堆肥醗酵舎は、アンモニアガスの発生が多く、鉄骨造りは非常に錆び易く、また従来工法の木造畜舎の木材接合は、ピン接合なので引張・圧縮による形状変化が出やすいものであった。
従来、木造構造物として木製トラス構造が非常に広く用いられている。その理由は、木製トラス構造はきわめて簡単に構成することが可能な上に非常に大きい荷重を支持することができるからである。
The livestock barn and compost fermentation house generate a lot of ammonia gas, the steel structure is very rusted, and the wood connection of the conventional method wooden barn is a pin connection, and it is easy to change its shape due to tension and compression.
Conventionally, a wooden truss structure is very widely used as a wooden structure. This is because the wooden truss structure can be constructed very easily and can carry very large loads.
そのため、三角形トラスの屋根用の骨組みを構成する木造トラス組構造が知られている(引用文献1を参照)。
この公知技術は、各梁材は、互いに釘留めされた少なくとも三つの基本板材から構成され、中央部に位置した板材は両側の板材に対してオフセットされ、これによって節点を形成する結合部にパネル形態の補強体を挿入するためほぞ及び/又はほぞ穴を形成するものであり、接合部位(節点)において接合されたパネルが釘留め領域を補足して、より大きな力に対して抗することができるものである。
Therefore, a wooden truss assembly structure that constitutes a roof truss of a triangular truss is known (see cited document 1).
In this known technique, each beam member is composed of at least three basic plate members that are nailed together, and the plate member located in the center is offset with respect to the plate members on both sides, whereby a panel is formed at a joint portion that forms a node. A tenon and / or mortise is formed to insert the form reinforcement, and the panel joined at the joint site (node) supplements the nail area and resists greater forces. It can be done.
また、骨組み構造体を主構造とした屋根部によって躯体構造部の変形を抑制させることで、躯体構造部の補強を必要としない複合構造建物が知られている(引用文献2を参照)。
この公知技術は、トラスを主構造として形成される屋根部と、その屋根部を下方から支持する鉄筋コンクリートによって形成されるRC部とからなる複合構造建物であり、トラスは桁側壁の上端面間に掛け渡されて固定される複数の陸梁を備えると共に、桁側壁の上端面及び妻側壁の上端面の少なくとも一端面を補強するために陸梁の少なくとも一部を組み入れた水平トラス構造を形成しているものである。
Moreover, the composite structure building which does not require reinforcement of a frame structure part is known by suppressing the deformation | transformation of a frame structure part by the roof part which made the frame structure main structure (refer the cited reference 2).
This known technique is a composite structure building composed of a roof portion formed with a truss as a main structure and an RC portion formed of reinforced concrete that supports the roof portion from below. A horizontal truss structure including at least a part of the land beam is provided to reinforce at least one end surface of the upper end surface of the girder side wall and the upper end surface of the girder side wall. It is what.
本発明は、アンモニアガスの発生が多い畜舎・堆肥醗酵舎などの建物に有効な三角形トラスの屋根用の骨組みを構成する木造トラス建物を提供することを目的とする。 An object of this invention is to provide the wooden truss building which comprises the frame | skeleton for the roof of a triangular truss which is effective for buildings, such as a livestock barn and a compost fermentation house with much generation | occurrence | production of ammonia gas.
本発明の木造トラス建物は、妻側壁上端面に沿って配置される陸梁と、該陸梁端部に結合されて屋根の勾配に合わせて配置される合掌と、前記陸梁と前記合掌との間に三角形トラスを形成するように斜めに配置される斜材と、前記陸梁と前記合掌、前記陸梁と前記斜材、前記合掌と前記斜材をそれぞれ突き当り結合し、それぞれを挟持して接着・釘留めにより固定する結合板とから構成されるものである。
本発明の木造トラス建物の組立方法は、陸梁と合掌、陸梁と斜材、合掌と斜材との接合部に固定される結合板で前記陸梁と前記合掌、前記陸梁と前記斜材、前記合掌と前記斜材を挟持し、それぞれ接着剤により固定し、さらに構造強度計算を行い、両面から釘を複数本×複数列を打ち込むものである。
The wooden truss building of the present invention includes a land beam arranged along the upper end surface of the side wall of the wife, a joint that is connected to the end of the land beam and is arranged in accordance with the slope of the roof, and between the land beam and the joint. The diagonal members arranged diagonally so as to form a triangular truss, the land beams and the joints, the land beams and the diagonal members, the joints and the diagonal members are brought into contact with each other, and each is sandwiched and bonded. -It is composed of a coupling plate that is fixed by nailing.
The method for assembling a wooden truss building of the present invention includes a land plate and a joint, a land plate and an oblique member, a joint plate fixed to a joint portion of the joint and the oblique member, and the land beam and the joint, the land beam and the oblique member. The material, the palm and the diagonal member are sandwiched and fixed with an adhesive, and the structural strength is calculated.
本発明の木造トラス建物は、妻側壁上端面に沿って配置される陸梁と、該陸梁端部に結合されて屋根の勾配に合わせて配置される合掌と、前記陸梁と前記合掌との間に三角形トラスを形成するように斜めに配置される斜材と、前記陸梁と前記合掌、前記陸梁と前記斜材、前記合掌と前記斜材をそれぞれ突き当り結合し、それぞれを挟持して接着・釘留めにより固定する結合板とから構成されるため、トラス形状として木材接合部を剛接合により引張・圧縮による形状変化を出にくくし、更に接合部(節点)の部材を金物ではなく、構造用合板として錆への対応をとってあり、また接合部(節点)には接着剤の塗布を行い強度の確保を行うことができる。
本発明の木造トラス建物の組立方法は、構造計算上は接着剤での計算はできないので、釘打ちにより構造強度計算をクリアし、更に接着剤により接合補強を行い、釘の劣化が進んでも急激な強度低下が起こらないものである。
The wooden truss building of the present invention includes a land beam arranged along the upper end surface of the side wall of the wife, a joint that is connected to the end of the land beam and is arranged in accordance with the slope of the roof, and between the land beam and the joint. The diagonal members arranged diagonally so as to form a triangular truss, the land beams and the joints, the land beams and the diagonal members, the joints and the diagonal members are brought into contact with each other, and each is sandwiched and bonded.・ Because it is composed of a connecting plate that is fixed by nailing, it is difficult to produce a shape change due to tension / compression of the wood joint as a truss shape by rigid joining, and the joint (node) is not a hardware structure. Corresponding to rust is taken as a plywood for use, and an adhesive can be applied to the joint (node) to ensure strength.
The method of assembling a wooden truss building of the present invention cannot be calculated with an adhesive in terms of structural calculation. Therefore, the structural strength calculation is cleared by nailing, and the joint is reinforced with an adhesive. The strength does not decrease significantly.
