この発ＢＡ灯、新規な立体トラスに於ける屋根構造の提
供に係わる。DETAILED DESCRIPTION OF THE INVENTION This BA light is related to the provision of a roof structure in a novel three-dimensional truss.
従来の立体トラスの屋根構造は、一般に、立体トラスの
上弦材又は下弦材に折板金属板又はコンクリート版等の
屋根仕上材を組付けてなるものであるが、当該屋根材の

使用する鉄骨の量は極めて大で、コスト高になるもので
あった。Conventional three-dimensional truss roof structures are generally constructed by assembling roof finishing materials such as folded metal plates or concrete slabs to the upper or lower chord members of the three-dimensional truss, but the total weight of the roofing materials is limited. The truss members must be huge in size, and in order to support them, especially those with large spans, the cross section increases and the grid shrinks.
The amount of steel used was extremely large, resulting in high costs.

た点にある。The present invention has been made in view of the above-mentioned circumstances, and its gist is that the upper and lower chord members of a three-dimensional truss are
Air is blown into the closed space formed when the membrane material of i: is stretched, and the internal pressure stabilizes the upper and lower membranes, greatly reducing the load on the truss members. The key point is that we achieved an economical three-dimensional truss frame by increasing the crid size and reducing the amount of steel.
以下、とれを図にもとづいて詳細に説明する。Hereinafter, the break will be explained in detail based on the drawings.

。In other words, Figure 1: asbtx Partial cut-down view of the roof structure of the present invention ff! i[II, In the longitudinal sectional view, 1 in the figure is a three-dimensional truss, and its upper chord member 1a and lower chord member 1b are made of class fibers and ultra-light ventral side 2 of Teflon coating film material.
are fixedly assembled, and the inside 3 and outside 4 of the three-dimensional truss 1 are cut off, creating a closed space between the three insides of the three-dimensional truss 1. Air is blown into this space, making the internal pressure slightly higher than the external pressure. This setting stabilizes the nuclear envelope material 2 in a stretched state.

しくは下弦材１ｂに対して押し止めてなるものである。The membrane material 2 is fixed to the upper, upper, and lower chord members 1a*ib, for example, as shown in FIG. In the foldable bag part, a core material 4 to prevent slipping is inserted into this, and the thick periphery is secured to the port 7 with a mounting clamp 6 via neoprene to prevent damage. It is pressed against the upper chord member 1a or the lower chord member 1b at the.
斜上構成にあっては、立体トラス罠組付く屋根仕上材の
重量は、大巾に軽減することとなる。In the diagonal top configuration, the weight of the roofing material to which the three-dimensional truss trap is assembled is significantly reduced.

いて有利でおる。Therefore, in accordance with the present invention, as the weight of the roof finishing material is reduced, the cross section of the three-dimensional truss member can be reduced and the grid can be increased, and the number of joints can be reduced, thereby reducing the amount of steel frame. It is possible to make a rational and economical design, and furthermore, because of the translucency of the membrane material 2, it has the advantage that the illumination is not visible during the day, which is particularly advantageous for large spans. I'll go.
