Film fixing tool, base member and plastic film applying method

本发明的目的是提高塑料薄膜的铺设作业的操作性。薄膜夹具1具有：被插入在与安装在温室的骨架材料等上的基础部件相对的侧板之间形成的空间部的第1固定部件10和第2固定部件20。通过第1固定部件10，可以发挥相对于塑料薄膜向一个方向产生拉力时抑制脱落的保持力，通过第2固定部件20，可以发挥相对于向另一个方向产生拉力时抑制脱落的保持力。相对于第1固定部件10，第2固定部件20被结合，被可以转动地设置。因此，只通过将第1固定部件的插入部11设置在基础部件的空间部内，同时也可使第2固定部件位于基础部件的空间部内，然后，只要使第2固定部件20转动、设置赋予势能装置即可。 The workability of plastic film applying operation is improved. A film fixing tool (1) has a first lock member (10) and a second lock member (20) that are adapted to be inserted in a space defined between the opposed side plates of a base member attached to a skeleton member of a greenhouse or the like. The first lock member (10) is capable of exerting a holding force to suppress the release of a plastic film when the latter is subjected to tension in one direction, while the second lock member (20) exerts a holding force to suppress such release when it is subjected to tension in the other direction. It is arranged that the second lock member (20) engages the first lock member (10) and is turnable. Therefore, by only positioning the insert section (11) of the first lock member (10) in the space in the base member, the second lock member (20) can also be simultaneously positioned in the space in the base member. Thereafter, it is only necessary to turn the second lock member (20) and install an urging means.
