在施工中如何避免防腐木开裂的现象

（贵州防腐木）

1、贵州防腐木销售厂家提醒在连接时应预先钻孔，这样可以避免开裂，胶水则应是防水的。

1, in the connection should be pre - drilling, so that it can avoid cracking, glue should be waterproof.

2、在施工中，假如可能的话，应该尽可能地使用现有的防腐木尺寸及外形，对浸渍材所做的任何加工，如钻孔、精刨、削切等会使浸渍材的使用寿命缩短。这样可以减少木材开裂的可能性。厚度大于38MM的林方，为了防止其变形，可在其木芯一面的中央线上开一个宽10MM，深10MM的小槽。

2, in construction, if possible, we should use the existing size and shape of the preservative wood as far as possible. Any processing done by impregnated materials, such as drilling, finishing and cutting, will shorten the service life of the impregnated wood. This can reduce the possibility of wood cracking. In order to prevent the deformation of 38MM, in order to prevent its deformation, a wide 10MM, deep 10MM slot can be opened on the central line of the wood core.

3、尽量使用二级以上的防腐木方，由于其含水率为20％以下，可以有效地防止开裂与变形。若一定要使用含水率大于20％的等级，则在施工现场，木方的叠放应做到每层有10-20MM的缝隙，并在施工前能放置于现场72小时以上，并在此期间防止阳光的直接照射。建议在施工顶用热镀锌及的钉子或螺丝做连接及安装。

3, as far as possible the use of more than two of the anticorrosion wood, due to its water content of less than 20%, can effectively prevent cracking and deformation. If we must use the grade of moisture content greater than 20%, then we should have a 10-20MM gap on each floor at the construction site, and put it on the scene for more than 72 hours before construction, and prevent direct sunlight exposure during this period. Recommended connection and installation in construction work and hot galvanized nails or screws.
