目前，抹面砂浆的应用仍相当普遍，但因施工作业面大、有障碍或多种原因，需中途间歇，会出现施工缝。下面济南抹面砂浆厂家来讲讲墙体抹灰留反槎的方法。

At present, the application of plastering mortar is still quite common. However, due to the large construction surface, obstacles or various reasons, the construction joints may occur if it needs to be interrupted halfway. Next, Jinan plastering mortar manufacturer will talk about the method of retaining reverse tenon in wall plastering.

1、无论内外墙底层抹灰或面层抹灰时，均应将需要留槎部位的墙面抹平槎麻或赶光压实，检查垂直度、平整度无误后，可将2m直尺水平或垂直方向压在欲留槎的部位，然后用铁抹子沿直尺下沿或一侧将多余的砂浆切掉;切除砂浆时，铁抹子尖应略向上或向尺身下挠斜，将斜槎切成60度左右，形成反槎。

1. When plastering the bottom layer or the surface layer of the internal and external walls, the wall surface where the tenon needs to be reserved shall be leveled or polished and compacted. After checking the verticality and flatness, press a 2m ruler horizontally or vertically on the part where the tenon is to be reserved, and then use an iron trowel to cut off the excess mortar along the lower edge or one side of the ruler; When cutting the mortar, the tip of the iron trowel shall be slightly upward or downward, and the oblique tenon shall be cut into about 60 degrees to form a reverse tenon.

2、当外墙有门窗或其他洞口时，抹灰留槎应尽量留在洞口上沿或下沿。

2. When there are doors and windows or other openings in the exterior wall, the plastering tenon shall be left at the upper or lower edge of the opening as far as possible.

为了保持洞口之间窗间墙外抹灰完整，在搭外脚手架时，应将脚手板的铁排木插入洞口上沿或下沿下降4皮砖的墙孔内。这样可给抹灰工留出运抹子空间，为施工缝留在佳位置创造条件。

In order to maintain the integrity of the external plastering between the windows between the openings, when erecting the external scaffold, the iron batten of the scaffold board should be inserted into the wall hole with 4 bricks falling from the upper or lower edge of the opening. This will leave space for the plasterer to transport the trowel and create conditions for the construction joint to stay in a good position.
