【発明の詳細な説明】
この発明は鉄道橋等を構成するコンクリートトラス梁の
施工法に関し、その目的は大型トラス梁の施工を容易か
つ確実に実施しうる方法を提供することにある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for constructing concrete truss beams constituting railway bridges, etc., and its purpose is to provide a method that can easily and reliably construct large truss beams.
現在鉄道鋼橋の騒音、経済性に対処すべくコンクリート
トラス橋の開発が研究されている。Currently, the development of concrete truss bridges is being researched to address the noise and economic issues associated with steel railway bridges.
ところでこのコンクリートトラス橋の梁高は４〜５ｒｒ
Ｌ以上、スパン４０〜６０ｍの大型となるためその施工
方法に種々問題がある。By the way, the beam height of this concrete truss bridge is 4~5rr.
Because it is large, with a span of 40 to 60 m, there are various problems with the construction method.
特に製作時に一体にコンクリート打ちをすることは困難
であり、単位部材の組立てを実施せざるを得ない。Particularly during manufacturing, it is difficult to pour concrete all at once, and it is necessary to assemble unit members.
この発明は前記要望に対処すべく開発されたものである
。This invention has been developed to meet the above-mentioned needs.
この発明の実施例を図面によって説明すると、第１図に

例えば橋のスパンに相当する長さに組立てて架設する。In this invention, first, a form (not shown) is assembled so that the unit truss 1 is formed horizontally, reinforcing bars are placed in the form, and then concrete is poured into the form.
The concrete is cured and hardened to form a unit truss, and then, after or during demolding, the unit truss is erected vertically as shown in Figure 2, and a plurality of these unit trusses 1 are installed at the upper and lower vertical joints 7. A truss of a predetermined length is bonded by bonding with mortar, synthetic resin adhesive, etc.
For example, it is assembled and erected to a length corresponding to the span of a bridge.
第３図は、単位トラスの他の実施例を示したものであり
、水平材と斜材とからなり、複数の三角格子目を連接し
たものを単位トラスとして構成したものである。FIG. 3 shows another embodiment of the unit truss, which is composed of horizontal members and diagonal members, and is constructed by connecting a plurality of triangular lattices.
この発明は以上の構成からなり、三角格子目の構成され
た単位トラスは横倒しの状態で形成されるので施工が比

速に行なうことができる。This invention has the above-mentioned configuration, and since the unit truss with the triangular lattice structure is formed horizontally, construction is relatively easy, and after erecting each unit truss, vertical joints Since it is joined, erection work is easy,
Furthermore, since the unit trusses erected at a site where erection is easy are assembled into spans, the erection work can be carried out easily and quickly.
