目前，抹面砂漿的應用仍相當普遍，但因施工作業(yè)面大、有障礙或多種原因，需中途間歇，會出現(xiàn)施工縫。下面濟南抹面砂漿廠家來講講墻體抹灰留反槎的方法。

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、無論內外墻底層抹灰或面層抹灰時，均應將需要留槎部位的墻面抹平槎麻或趕光壓實，檢查垂直度、平整度無誤后，可將2m直尺水平或垂直方向壓在欲留槎的部位，然后用鐵抹子沿直尺下沿或一側將多余的砂漿切掉;切除砂漿時，鐵抹子尖應略向上或向尺身下?lián)闲?，將斜槎切?0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、當外墻有門窗或其他洞口時，抹灰留槎應盡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.

為了保持洞口之間窗間墻外抹灰完整，在搭外腳手架時，應將腳手板的鐵排木插入洞口上沿或下沿下降4皮磚的墻孔內。這樣可給抹灰工留出運抹子空間，為施工縫留在佳位置創(chuàng)造條件。

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.
