砼散水施工留置变形缝及缝内嵌沥青砂浆,施工繁锁、周期长,质量不易控制。我公司通过实践,改变了散水变形缝施工作法,其成品达到了预效果。 施工方法是:提前预制沥青砂浆条备用。尺寸满足工程要求,原则上厚度为20mm,高度同散水厚,长度同散水宽。施工时,按图纸要求在变形缝位置拉线,外边线仍用木板支模,靠墙及分格线均固定沥青砂浆条,方法似固定磨石地面中分格条,浇灌散水砼并随打随抹,届时养护,待强度达1.2MPa后,用钢制烙子烫熨
砼Disposing the deformation joints in the construction of loose water and embedding the asphalt mortar in the joints, the construction is cumbersome, the cycle is long, and the quality is difficult to control. Through practice, our company has changed the work method of dispersive water deformation joints, and its finished products have achieved pre-effects. The construction method is: pre-prepared asphalt mortar bar spare. The dimensions meet the engineering requirements. In principle, the thickness is 20mm, the height is the same as the bulk water thickness, and the length is the same as the bulk water. During the construction, pull the wire at the location of the deformation joint according to the requirements of the drawings, and use the wood mold for the outer line. Fix the asphalt mortar bar against the wall and the dividing line. The method is like fixing the grindstone in the grindstone ground, and pouring the water into the concrete and follow it. Wipe, then conservation, until the strength reaches 1.2MPa, iron ironing with steel
