Description

本発明は、屋根の勾配に沿って傾斜し、かつ建物壁部の上部に設けられた天井枠に組み付けられる屋根トラス部材の組立方法に関する。 The present invention relates to a method for assembling a roof truss member that is inclined along a roof gradient and is assembled to a ceiling frame provided on an upper portion of a building wall.

従来、２×４インチ等の規格化された木材で枠組を作成し、この枠組に対し、構造用合板等の面材を取り付けて建物を構築する枠組壁工法が知られている。また、前記木材を予め工場で採寸、切断および座掘り加工しておくことによって、現場での作業量を減らすことが可能な技術も知られている。 2. Description of the Related Art Conventionally, there has been known a frame wall construction method in which a frame is made of standardized wood such as 2 × 4 inches and a building is constructed by attaching a face material such as a structural plywood to the frame. There is also known a technique capable of reducing the amount of work on site by measuring, cutting and spotting the wood in advance in a factory.

以上のような建物の構築方法によれば、建物や敷地条件に左右されること無く建物を構築することができるという利点がある。
ところが、このような方法で作業を行う場合は、現場に納入される木材等の建築材料の数が非常に多く、その分だけ作業手間が増えるので、工期が長くなってしまうだけでなく、正確な作業手順等を熟知した多くの熟練作業者を確保しなければならないという問題があった。 According to the building construction method as described above, there is an advantage that the building can be constructed without being influenced by the building or site conditions.
However, when working in this way, the number of building materials such as timber delivered to the site is very large, and the work is increased by that much. There is a problem that a lot of skilled workers who know the detailed work procedure etc. must be secured.

そこで、このような問題を解決すべく、予め工場で前記木材をパネル化しておき、このようにパネル化したものを現場でクレーンによって建て込むだけで、比較的容易に建物を構築することができるような技術が開発されている（例えば、特許文献１参照）。
特開２０００−２５７１５２号公報 Therefore, in order to solve such a problem, it is possible to construct a building relatively easily simply by panelizing the wood in a factory in advance and building the panel in this way with a crane on site. Such a technique has been developed (see, for example, Patent Document 1).
JP 2000-257152 A

ところで、上記特許文献１に記載の技術においては、現場作業者にそれほど高い技能が無くとも品質が安定するということと、工期を短縮することができるという利点がある。
しかし、このように木材をパネル化したものを用いた場合は、パネル化しない場合に比して生産に係るコストが高くなるだけでなく、材料がパネル化して大きくなった分、輸送に係るコストも高くなってしまう場合があった。 By the way, in the technique of the said patent document 1, even if a field worker does not have so high skill, there exists an advantage that quality can be stabilized and a construction period can be shortened.
However, using wood paneled in this way not only increases the cost of production compared to the case without paneling, but also increases the cost of transportation as the material becomes panelized. In some cases, it would be too high.

そこで、以上のような諸問題を解決し得る技術の開発が強く望まれていた。特に、屋根部においては、例えば天井梁部材や天井根太部材、垂木部材、隅垂木部材、屋根トラス部材等の建築材料が多く用いられるので、作業の簡略化や工期の短縮等、より施工性を向上させたいという要望が強かった。 Therefore, development of a technology that can solve the above problems has been strongly desired. In particular, in the roof part, for example, a lot of building materials such as ceiling beam members, ceiling joists, rafter members, corner rafter members, roof truss members, etc. are used. There was a strong demand for improvement.

中でも、屋根部を支持するための主要な建築材料となる前記屋根トラス部材は、この屋根トラス部材を構成する複数の部材を正確に組み立てる必要があると同時に、作業用足場等の高所での組立作業を行う場合もあるので、より簡略に組立作業を進めることが可能な技術の開発が望まれていた。 Above all, the roof truss member, which is the main building material for supporting the roof part, needs to assemble a plurality of members constituting the roof truss member accurately and at the same time at a high place such as a working scaffold. Since there is a case where assembly work is performed, it has been desired to develop a technique capable of proceeding with the assembly work more simply.

本発明の課題は、建物全体の施工性について総合的に考慮しつつ、特に、屋根部の施工性を格段に向上させることができるとともに、正確、かつ簡略に屋根トラス部材を組み立てることが可能な屋根トラス部材の組立方法を提供することを目的とする。 The subject of the present invention is that it is possible to remarkably improve the workability of the roof part in particular while comprehensively considering the workability of the entire building, and it is possible to assemble the roof truss member accurately and simply. An object is to provide a method for assembling a roof truss member.
