来源: 日期:2019-12-02 发布人:admin

  一、麻面

  I. surface
  现象:灌浆料部分外表现象呈现缺浆和许多小凹坑、麻点,构成粗糙面,但无钢筋外露现象。
  Phenomenon: the appearance of grouting material part shows lack of grout and many small pits and pockmarks, forming a rough surface, but no reinforcement exposed.
  产生的缘由
  Why it came into being
  1模板拼缝不严,部分漏浆;
  1. The joint of formwork is not tight, and part of formwork is leaked;
  2模板隔离剂涂刷不匀,或部分漏刷或失效,灌浆料外表与模板粘结形成麻面;
  2. The formwork isolating agent is not evenly applied, or part of it is missing or invalid, and the surface of grouting material is bonded with the formwork to form a pitted surface;
  3模板外表粗糙或粘附水泥浆渣等杂物未清算洁净,拆模时灌浆料外表被毁坏;
  3. The surface of the formwork is rough or the sundries such as cement slurry slag are not cleared and cleaned, and the surface of the grouting material is damaged when the formwork is removed;
  4模板未浇水潮湿或潮湿不够,构件外表灌浆料的水分被吸去,使灌浆料失水过多呈现麻面;
  4. The formwork is not watered wet or not wet enough, and the moisture of the grouting material on the surface of the component is absorbed, which makes the grouting material lose too much water and present a pitted surface;

  5灌浆料振捣不实,气泡未排出,停在模板外表现象构成麻点。
  5. The grouting material is not vibrated properly, the bubbles are not discharged, and it stops on the surface of the formwork to form pockmarks.
  防治措施
  Preventive measures
  1模板外表清算洁净,不得粘有干硬水泥砂浆等杂物;浇灌灌浆料前,模板应浇水充沛潮湿;模板缝隙,应用油毡纸、腻子等堵严;模板隔离剂应选用长效的,涂刷平均,不得漏刷;灌浆料应分层平均振捣密实,至扫除气泡为止;
  1. The surface of the formwork shall be clean and free of dry and hard cement mortar and other sundries; before grouting, the formwork shall be watered with sufficient moisture; the gaps of the formwork shall be blocked with felt paper and putty; the long-term formwork isolating agent shall be selected and brushed evenly without missing; the grouting material shall be vibrated and compacted evenly by layers until the bubbles are removed;
  2. 外表作粉刷的,可不处置,外表现象无粉刷,应在麻面部位浇水充沛潮湿后,可用1:2或1:2.5水泥砂浆,将麻面抹平压光。
  2. If the surface is painted, it is not necessary to deal with it. If there is no painting on the surface, the hemp surface can be leveled and polished with 1:2 or 1:2.5 cement mortar after the hemp surface is fully watered and wet.
  二、外表不平整
  II. Uneven appearance
  现象:灌浆料外表凹凸不平,或板厚薄不一,外表不平。
  Phenomenon: the surface of grouting material is uneven, or the thickness of the board is different, and the surface is uneven.
  产生的缘由
  Why it came into being
  1.灌浆料浇筑后,外表仅用铁锹拍子,未用抹子找平压光,形成外表粗糙不平;
  1. After the grouting material is poured, the surface is only leveled with spade and troweled without trowel, resulting in rough and uneven surface;
  2.模板未支撑在坚硬土层上,或支承面缺乏,或支撑松动、泡水,致使新浇灌灌浆料早期养护时发作不平均下沉;
  2. The formwork is not supported on the hard soil layer, or the bearing surface is lack, or the support is loose and water is soaked, which causes the uneven sinking of the new grouting material during the early maintenance;
  3.灌浆料未到达一定强度时,上人操作或运料,使外表现象呈现凹陷不平或印痕。
  3. When the grouting material does not reach a certain strength, the operator shall operate or transport the material to make the appearance appear concave, uneven or imprinted.
  防治措施
  Preventive measures
  严厉按施工标准操作,浇筑灌浆料后,应依据程度控制标志或弹线用势抹子找平、压光,终凝后浇水养护;模板应有足够强度、刚度和稳定性应支在坚实地基上,有足够的支撑面积,并避免浸水,以保证不发作下沉;在浇筑灌浆料时,增强检查,灌浆料强度到达1.2N/㎜2以上,方可在已浇构造上走动。
  Operate in strict accordance with the construction standards. After grouting materials are poured, level and polish with a potential trowel according to the degree of control marks or snapping lines, and water for maintenance after final setting. The formwork shall have enough strength, rigidity and stability, which shall be supported on a solid foundation, with enough supporting area, and avoid flooding to ensure no sinking. When grouting materials are poured, strengthen the inspection, and the strength of grouting materials shall reach 1.2N /Only when it is more than 2 mm can it walk on the poured structure.
