利用竹材做建筑物代替钢材及木材,在今天祖國社会主義建設有著重大的意義。竹材的性能在許多方面有其优点的,但是也還有许多缺点。(如中空端头、收縮开裂、易腐及生虫等。)假如不能克服其缺点,則其优点是不能很好利用的。本文针对竹材的中空端头、收縮开裂等缺点進行改造加工。通过試驗及研究證明:利用酪素—水泥膠把廢木料圆(?)或木板膠入竹桿或竹片端头或有節点处,这样竹桿件所制造出的各种型式竹結構是完全类似木結構的,可以說由構造上解决了結合困难,並且有了安全的保証。本文首先介紹了此型竹結結構的各种图式及合适跨度(图1),然后介紹竹桿的基本改選方法(圖3)及各式節点的構造方案(圖4),以及其簡單計算的举例(§2-7);最后简要介紹有关改造加工的施工工藝(§3)。本文認为若用作过防腐及防虫处理的竹材,再通过以上改造所制造的竹結構会能够比較安全的長期使用。(半永久性的而不再是臨时性的建筑。)
The use of bamboo as a substitute for steel and timber in buildings is of great significance in today’s socialist construction of the motherland. The properties of bamboo have advantages in many aspects, but there are also many shortcomings. (Such as hollow head, shrinkage, cracking, perishable, and worms.) If you can’t overcome its shortcomings, the advantages are not very good. This article aims at the hollow end of bamboo, shrinkage cracking and other shortcomings transformation processing. Through tests and studies, it has been proved that the use of casein-cement glue to round waste wood or plastic boards into the ends or joints of bamboo rods or bamboo strips, so that all kinds of bamboo structures produced by bamboo rods are completely similar. The wooden structure can be said to have solved the difficulties in combination and ensured the safety. This article first introduced various patterns and suitable spans of this type of bamboo knot structure (Fig. 1), and then introduced basic methods for selecting bamboo rods (Fig. 3) and various node construction schemes (Fig. 4) and their simple calculations. Examples (§ 2-7); Finally, a brief introduction to the construction process (§ 3). This article believes that if used as a bamboo material for over-preservation and pest control, the bamboo structure manufactured through the above transformation can be used safely for a long period of time. (Semi-permanent and no longer a temporary building.)
