一.浇注料施工前的检查:
(1)检查待浇注设备的表面及其清洁情况,要求施工表面必须清洁。
check the surface and cleaning of the equipment to be cast, and it is necessary to clean the surface of the construction.
(2)检查施工机具的完好情况,搅拌、振捣工具等必须有完好的备件。
Check the integrity of the construction machinery and equipment, mixing, vibrating tools and so on must have good spare parts.
(3)检查锚固件的形状、尺寸、布置及焊接质量,金属锚固件必须做好膨胀补偿处理(涂上沥青或其他措施)。
Check the shape, size, layout and welding quality of the anchor, and the metal anchor must be done with the expansion compensation process (coated with asphalt or other measures).
(4)检查周围耐火砖衬及隔热层预防浇注料失水的防范措施。
Check the surrounding refractory and heat insulation layer to prevent water loss of castable preventive measures.
(5)检查浇注料的包装和出厂日期,并进行预试验检查是否失效。
Check the packing and delivery date of the casting material, and do the pre test to check whether it is invalid.
(6)检查施工用水,水质必须达到饮用水的标准。
Check construction water, water quality must meet the standards of drinking water.
凡是上述项目检查不合格时应处理合格后方可施工,过期失效的浇注料不得使用,浇注料施工中要确保不停电并不得中断施工。
All the above items should be handled when the project is not qualified to deal with the qualified rear can be constructed, expired failure of the casting material shall not be used, pouring material construction to ensure that no power outages and not interrupted construction.
二.施工时的注意事项:
(1)模板:浇注料施工用模板可用钢板或硬木版(五合板)制成,模板要有足够强度,刚性好,不走形,不移位,不漏浆,刚模板要涂脱模剂,木模板要涂防水剂,重复使用的模板要先清洗,再涂漆方可使用。点检孔和清扫孔要用木头作出规则的模壳。支撑木魔板的金属拉筋每平方米应多于4根(防止强烈传热)且拉筋应以锚固件为基础焊接(也就是模板的拉筋应焊接在锚固件上)。
Template templates are available: plate or hardwood version construction castable (wugeban) made of template to have enough strength, good rigidity, no shape, no movement, no leakage, rigid template to mold release agent, wood template should be coated with waterproof agent, the repeated use of the template before cleaning, painting can be used. The shell mould inspection hole and hole cleaning to make rules with wood. Wood magic board metal lacing per square meter should be more than 4 (to prevent strong heat transfer and reinforcement) should be based on anchor welding (i.e. template reinforcement should be welded on the anchor).
(2)水灰比:搅拌浇注料时的加水量要严格按照说明书控制,不得超过限量,在保证施工性能的前提下,加水量宜少不宜多。
Water cement ratio: the amount of water should be strictly in accordance with the specification control, shall not exceed the limit, under the premise of ensuring the performance of the construction, the amount of water should be less.
(3)搅拌:浇注料的搅拌时间应不少于5分钟(以说明书的要求为准),操作时要用强制式搅拌机。搅拌时宜先干混搅拌,再加入80%用量的水搅拌,然后视其干湿程度,徐徐加入剩余的水继续搅拌,直到获得适宜的工作程度为止。搅拌不同的浇注料要将搅拌机清洗干净。
Mixing: castable mixing time should not less than 5 minutes (to the requirements of the specification shall prevail), the operation to use forced mixer. Mixing should first dry mixing, adding 80% dosage of water mixing, and then the wet and dry, slowly stir the remaining water, straight to get comfortable the stirring casting material so far. Different to the mixer clean.
(4)浇注料的使用:浇注料必须整桶整袋地使用,搅拌好的浇注料一般必须在30分钟内用完,在高温干燥的作业环境中还要适量缩短这一时间,已经初凝甚至结块的浇注料不得倒入模框内,也不得再加水后搅拌使用。
The use of castable castable must use the whole barrel bag, stirring the castable generally must be used within 30 minutes in the hot and dry environment but also reduce the amount of the time, has been at the beginning of castable coagulation even caking not into the mould frame, it may not use the water after mixing.
(5)振动:倒入模框内的浇注料应立即用振动棒分层震实,每层高度应不大于300mm,振动间距以250mm左右为宜。振动时应尽量避免触及锚固件,不得损伤隔热层,不得在同一位置上久振或重振,看到浇注料表面返浆后应将振动棒缓慢抽出,避免浇注料层产生离析现象和出现空洞。
Vibration: pour castable mold box should be immediately with a vibrating rod layered jolt, the height of each layer should be less than 300mm, the vibration spacing was about 250mm. The vibration should be avoided when touching the anchor, shall not damage the insulation layer, not to revive long vibration or in the same position, see the pouring material surface slurry return should slow vibration stick out, avoid pouring layer segregation and hollow.
(6)大面积施工:在大面积施工过程中,要分块施工,每块浇注区的面积以1.5m2左右为宜,膨胀缝要按照设计要求留设,不得遗漏,膨胀缝应留设在锚固件间隔的中间位置,膨胀缝可以使用6~8mm厚的木板,木板的断面距模板的距离应为40~60mm,膨胀用木板应进行有效固定,防止在浇注料施工过程中易位。
The construction of large area: a large area in the construction process, to block construction, each pouring area at about 1.5m2 is appropriate, according to the design requirements of expansion joint setting, without loss, expansion joints should be located in the middle position left anchor spacing, expansion joints can be used 6~8mm thick plank, distance from template the wood section should be 40~60mm, the expansion board should be effectively fixed, prevent the translocation during the construction of the pouring material.
(7)关于锚固件的焊接:在工作面上划出网格线(按照图纸的要求),在网格线接点的位置上焊接锚固件,锚固件根部的焊接要满焊。
On the anchor of the welding: in the working face to draw the grid lines (in accordance with the requirements of the drawings), the location of the grid lines in the welding anchor, anchor the root of the welding to be filled.
(8)浇注料施工完成后的浇注体,在凝固前不得再经受压力或受震。
After the construction of the pouring material is completed, the casting body is not subjected to pressure or shock before it is solidified.
三.施工后的保养检查:Maintenance inspection after construction:
(1)待浇注料表面干燥后,应立即用塑料薄膜或草袋将露在空气中的部分盖严实,初凝达到后要定期洒水养护,保持其表面湿润,养护时间至少两天,第一天内要勤洒水。浇注料终凝后方可拆除模板继续洒水养护,但承重模板必须待强度达到70%以后方可拆模。
(1) to be castable after surface drying, should immediately use plastic film or straw bags will be exposed in the air tight cover part, the initial setting reached after regular watering and maintenance, keep the surface moist curing time for at least two days, the first day to wash water. Pouring material be removed after final setting template to sprinkler maintenance, but bearing template must be after the strength reached 70% can tear open mode.
(2)模板拆除后要及时对浇注体进行检查,发现蜂窝、剥落和空洞等质量问题要及时处理与修补,问题严重时要将缺陷部位凿去,露出锚固件,再用相同质量的捣固料填满捣实,继续养护,严禁用水泥灰浆抹平来掩盖问题。
After removing the template to the casting body timely inspection, found quality problems of honeycomb, spalling and cavity to timely treatment and repair of serious problems to the defective parts to cut the anchor, exposed, with the same quality of tamping material to fill compaction, to maintenance, no water mud mortar moping to cover up the problem.
四.浇注料施工的检查和验收:
1.浇注料施工过程中,每20m2工程量要留设试块一组,以便检查其强度等主要性能。
2.凡被覆盖的隐蔽工程,应在隐蔽工程验收后,方可进入下一道工序,其检查项目如下:
(1)隔热层和锚固砖,模板等(随时检查)(2)锚固件和锚固装置
(3)防失水措施(4)预埋设施
隐蔽性工程检查后,应填写隐蔽性工程验收单,并在建设单位签证认可后,作为竣工资料之一。
3.分项工程完工后,应进行中间交工验收,其检查项目如下:
(1)砌体的外形尺寸、衬厚和中心线(2)材料使用情况
(3)膨胀缝、砖缝、水平度、垂直度和表面平整度
