用于修复孔的后备装置。 在一些实施例中，孔位于壁中，例如在例如家庭或建筑结构的壁（例如，垂直壁，天花板等）中的相对较大的孔。 背衬装置包括可折叠背衬构件和粘合剂条。 背衬构件限定与后表面相对的前表面，并且包括连接在铰链段处的第一和第二面板。 粘合带设置在前表面上。 背衬构件可从平坦状态折叠到折叠状态，以插入通过壁孔。 一旦部署在墙壁的后面，背衬构件就转变到平坦状态，并且用于将背衬装置固定到墙的后表面的粘合带。 在一些实施例中，背衬装置在平坦状态下在一个方向上相对刚性并且在相反方向上可折叠。

Useful backing device to repair the hole. In some embodiments, the hole is at the present to the wall, for example, a relatively large hole, such as a wall of the house or building structures (e.g., vertical walls, ceilings, etc.). And the backing device comprises a backing member can be folded and adhered strips. The backing member includes a front surface and a first and a second panel connected to the hinge segment to form the other side of the rear surface, accordingly. The adhesive strip is disposed on the front side. The backing member is folded in a folded state from the flat state to the insertion hole through the wall. Once the wall "behind" development, the backing member is a transition to a flat state, the adhesive strip is used to secure the device to the rear surface of the backing wall. In some embodiments, the backing device is in the flat state, relatively rigid in one direction and can be folded in the opposite direction.
