目前,在农村建筑中,木结构应用得还比较广泛,而木结构的传统做法存在着许多不科学、不合理的现象。现对农村建筑主要承重结构中的梁、檩等受弯构件,介绍几种合理使用木材的方法。一、破一为二和破一为三农村建房常用八寸径或一尺(约33.33厘米)径的圆木作一丈左右长的檩子。这是一种材料上的浪费。可以将八寸径圆木破一为二、把一尺径圆木破一为三使用。八寸径圆木破一为二(图1甲)的破法有二种:一是从B线破一为二,然后稍加削修成为图1乙形状,即成
At present, the use of wood structures in rural buildings is still relatively extensive, and there are many unscientific and unreasonable phenomena in the traditional practices of wood structures. Now we introduce some methods for the rational use of wood, such as beam and concrete bending elements in the main load-bearing structure of rural buildings. First, break one for two and break one for three rural rounds of eight-inch diameter or one foot (about 33.33 centimeters) diameter round wood for the construction of a house about ten feet long. This is a waste of materials. Eight-inch diameter roundwood can be broken into two, and one-foot diameter roundwood can be used as three. There are two ways to break the eight-inch diameter round wood (Figure 1A): one is broken from the B line to one, and then a little cut to become Figure 1 B shape, ready-made
