木材泛指用于工民建筑的木制材料,通常被为软材和硬材。工程中所用的木材主要取自树木的树干部分。木材因取得和加工容易,自古以来就是一种主要的建筑材料。

木材按树种进行分类,一般分为针叶树材和阔叶树材。

防腐木是采用防腐剂渗透并固化木材以后使木材具有防止腐朽菌腐朽功能、生物侵害功能的木材。种类

木材可分为针叶树材和阔叶树材两大类。杉木及各种松木、云杉和冷杉等是针叶树材;柞木、水曲柳、香樟、檫木及各种桦木、楠木和杨木等是阔叶树材。中国树种很多,因此各地区常用于工程的木材树种亦各异。东北地区主要有红松、落叶松(黄花松)、鱼鳞云杉、红皮云杉、水曲柳;长江流域主要有杉木、马尾松;西南、西北地区主要有冷杉、云杉、铁杉。

密度是某一物体单位体积的质量,通常以g/cm³ 或kg/m³ 表 示。木材系多孔性物质,其外形体积由细胞壁物质及孔隙(细胞腔、胞间隙、纹孔等)构成,因而密度有木材密度和木材细胞物质密度之分。前者为木材单位体积(包括孔隙)的质量;后者为细胞壁物质(不包括孔隙)单位体积的质量。

木材密度:是木材性质的一项重要指标,根据它估计木材的实际重量,推断木材的工艺性质和木材的干缩、膨胀、硬度、强度等木材物理力学性质。木材密度,以基本密度和气干密度两种为最常用。

木方,俗称为方木,将木材根据实际加工需要锯切成一定规格形状的方形条木,一般用于装修及门窗材料,结构施工中的模板支撑及屋架用材,或做各种木制家具都可以。

主要由松木、椴木、杉木等树木加工成截面长方形或正方形的木条。

装修中常用的一种材料,有多种型号,用于撑起外面的装饰板,起支架作用。天花吊顶的木方一般松木方较多。一般规格都是4米长,有2*3cm的3*4cm的,4*4cm的等。

土建中模板支架也是木方常用的一种材料,市面常见的有50×100的,40×90的,35×85的,40×80的等。

木托盘以原木为材料,进行干燥定型处理,减少水分,消除内应力,然后进行切割、刨光、断头、抽边、砂光等精整加工处理而形成型材板块,采用具有防脱功能的射钉(个别情况采用螺母结构)将型材板块装订成半成品托盘,最后进行精整、防滑处理和封蜡处理。木托盘是现在使用最广的托盘。托盘是用于集装、堆放、搬运和运输的放置作为单元负荷的货物和制品的水平平台装置。一般用木材、金属、纤维板制作,便于装卸、搬运单元物资和小数量的物资。
