水泥砂浆抹面消除施工缝的方法有哪些?

来源: 日期:2022-04-14 发布人:juyehe

目前,水泥砂浆抹面的应用仍相当普遍,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。由于对抹灰施工缝轻视,处理草率,所以继续施工时,新旧抹面接搓处的施工缝即形成痕迹,有碍观瞻,往往被目测质量检查减分,形成了易发的质量通病。

At present, the application of cement mortar plastering is still quite common, but due to large construction surface, obstacles or various reasons, it needs to be intermittently, and construction joints will appear. Due to the neglect and careless treatment of the plastering construction joint, when continuing the construction, the construction joint at the joint of the old and new plasters will form a trace, which is unsightly and often reduced by the visual quality inspection, forming a common quality problem.
为此小编将摸索出留反槎的作法分享发给大家,这种方法简便易行,被工人誉为“解决抹灰施工缝的绝招”。现将具体作法介绍如下。
To this end, Xiaobian will share with you the practice of leaving reverse tenon. This method is simple and easy, and is praised by workers as "the unique skill to solve the plastering construction joint". The specific methods are introduced as follows.
一、墙体抹灰留反槎的方法
1、 Method of retaining reverse tenon for 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 surface layer of the internal and external walls, the wall surface where the tenon needs to be reserved shall be smoothed, tenoned or polished and compacted. After checking the perpendicularity and flatness, press the 2m ruler horizontally or vertically on the position where the tenon needs to be reserved, and then cut off the excess mortar along the lower edge or one side of the ruler with an iron trowel; When cutting the mortar, the tip of the iron trowel shall be slightly upward or downward inclined to the ruler body, and the inclined 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, windows or other openings in the outer wall, the plastering tenon shall be left on 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,为施工缝留在位置创造条件。
In order to maintain the integrity of the plastering outside the window wall between the openings, when erecting the external scaffold, the iron row wood of the scaffold board shall be inserted into the wall hole with 4 bricks falling from the upper or lower edge of the opening. This can leave space for plasterers to transport trowels and create conditions for construction joints to remain in place.
3、室内墙体抹灰留反槎的几个部位:
3. Several parts with reverse tenon left for indoor wall plastering:
1)每上下两步脚手架交接处应留反槎。
1) Reverse tenon shall be reserved at the junction of the scaffold at each up and down steps.
2)电表箱、闸箱、消防箱等需要镶入墙体内的设施(备)不能及时供货时,在洞口四周100mm处留反槎。
2) When the facilities (standby) that need to be embedded in the wall such as electricity meter box, gate box and fire box cannot be supplied in time, an inverted tenon shall be reserved at 100mm around the hole.
3)外脚手架穿墙的铁排木或卸载的钢丝绳凸出内墙面且影响抹灰时,需在管端或钢丝绳两侧100mm范围内留反槎。
3) When the iron row wood passing through the wall of the outer scaffold or the unloaded steel wire rope protrudes from the inner wall and affects the plastering, the reverse tenon shall be reserved within 100mm on both sides of the pipe end or steel wire rope.
4)门口、哑巴口(无门框)、暖气槽两侧未抹1:2水泥砂浆护角时,应在洞、槽边缘以外100mm外留反槎。
4) When 1:2 cement mortar corner protection is not plastered on both sides of the door, dumb mouth (without door frame) and heating slot, reverse tenon shall be reserved 100mm outside the edge of the hole and slot.
5)距踢脚板高度上方50~100mm外留反槎。
5) Reverse tenon shall be reserved outside 50 ~ 100mm above the height of skirting board.
6)在采暖或给水穿墙横管四周50~100mm外留反槎。
6) Reverse tenon shall be reserved outside 50 ~ 100mm around the horizontal pipe passing through the wall for heating or water supply.
7)厨厕间屋顶穿楼板立管未封堵预留孔而提前抹灰时,在孔四周50~100mm外留反槎。
7) When the floor riser on the roof of the kitchen and toilet room is plastered in advance without blocking the reserved hole, an inverted tenon shall be reserved outside 50 ~ 100mm around the hole.

二、地面抹灰留反槎的方法
2、 Method of reserving reverse tenon for ground plastering
1、水泥砂浆地面面积很大时,需分段、分块施工,在段或块的间断处要留反槎。
1. When the cement mortar floor area is large, it needs to be constructed in sections and blocks, and the reverse tenon shall be reserved at the discontinuity of sections or blocks.
2、各居室与方厅或各办公室与走廊之间,应在门洞口门框侧口外及哑巴口1/2处留反槎。如果不留槎,也可设一道玻璃条。
2. Between each bedroom and the square hall or between each office and the corridor, reverse tenon shall be reserved outside the side opening of the door frame at the door opening and 1 / 2 of the mute opening. If no tenon is left, a glass strip can also be set.
三、修补墙(地)面施工
3、 Repair wall (ground) surface construction
1、当墙(地)面出现空鼓、裂缝需修补时,用此方法可收到很好的效果。
1. When hollows and cracks appear on the wall (ground) surface and need to be repaired, this method can achieve good results.
2、抹灰层空鼓或裂缝需要修补时,可用粉笔画出其位置,用无拉齿锯沿粉笔印割缝,锯身应向修补范围倾斜。
2. When the hollowing or crack of the plastering layer needs to be repaired, its position can be drawn with chalk, and the slit shall be cut along the chalk mark with a non pulling tooth saw, and the saw body shall be inclined to the repair range.
剔凿创口内硬结砂浆时,可用人工手持钢钎、手锤适力作业,冲凿力不能过大,以免振动扩大墙(地)面空鼓范围。
When chiseling the hardened mortar in the wound, the manual hand-held steel chisel and hammer can be used for appropriate force operation. The punching and chiseling force shall not be too large to avoid vibration and expand the hollowing range of the wall (ground) surface.
