运动PVC地板施工工艺及验收标准。
 
文摘:
 
1。地面必须保持干燥,干燥,无裂缝。2。混凝土地面含水量不得超过3%。三。保持地面平整度:地面表面与2m尺的距离相差不超过3mm。4。运动木地板、复合木地板、瓷砖、大理石地板和大理石地板可以直接铺设。
 
 
 
1。地面探测
 
1、使用温湿度计检测温湿度,室内温度和表面温度为15℃,不得低于5摄氏度或超过30℃,施工的相对湿度应限制在20%-75%之间。
 
2。用含水量测定仪测定碱液的含水量,碱液的含水量应小于3%。
 
3、基层强度不得低于混凝土强度C-20的要求,否则应采取适当的自流平加固。硬度测试仪的测试结果应为基体表面硬度不小于1.2MPa。
 
5、PVC地板施工时,基层的粗糙度应在2米以内,高低差小于2毫米,否则应采用适当的自流平进行平整。
 
二、地板前处理
 
1、用1000瓦以上的地板磨床用适当的地板整体磨削,去除油漆、胶水等残留物,鼓起和松动地块,必须清除空地块。
 
2、使用不少于2000瓦的工业真空吸尘器清洁地面。
 
三。对于地面裂缝,采用不锈钢补强和聚氨酯防水胶粘剂对石英砂表面进行修补。
 
三、自流平施工-筑底
 
1。可吸收基层,如混凝土和水泥砂浆调平层,应该用多用途的界面处理剂处理,用水按1:1的比例稀释。
 
2。非吸收性底座,如瓷砖、水磨石、大理石等,建议采用密实型。
 
采用表面处理剂进行底料处理。
 
3、如果基材含水量过高(>3%),需要立即施工,则可以使用环氧界面处理剂进行底部处理,但前提是基材的含水量不应超过8%。
 
4、界面处理剂的结构应均匀,无明显的液体积聚。界面处理剂表面风干后,可进行下一步的自流平施工。
 
四、自流平施工-混合
 
1、根据规定的水灰比,将自流平包装物倒入清水搅拌桶内,倾倒搅拌。
 
2。为了保证自调匀整的均匀混合,必须采用大功率、低转速的电钻与专用搅拌器混合。
 
3、搅拌至不结块均匀浆料,静置和成熟约3分钟,然后短暂搅拌一次。
 
4、加水量应严格按照水灰比(请参阅相应的自流平手册)。水太少会影响流动性。过多会降低固化后的强度。
 
五、自动找平施工
 
1、自流平浆料搅拌好倒在地板施工中,将自动流平地面,如果设计厚度小于或等于mm,则需要专用刮齿机。
 
2、应随施工人员佩戴专用钉,进入施工现场,用自流平辊进行放气,在自流平表面轻轻滚动,在混合空气中释放混合气,避免气泡坑和界面高度。
 
3、施工完成后,请立即关闭现场,5小时内不得行走,10小时内避免重物撞击,24小时后铺设PVC地板。
 
4、在冬季施工中,自流平施工后应铺设48小时。
 
5、如果需要对自流平进行抛光和抛光,应在自流平施工12小时后进行。
 
六、地板铺装、预铺和切割
 
1、无论是否应在散装材料中,放置24小时以上,减少材料记忆,温度与施工现场一致。
 
2。使用特殊的修整机切割和清洗材料的边缘。
 
3、大块铺设时,两块材料之间应接近且无接缝。
 
4、铺设轧制材料时,两块材料的搭接应采用重叠切削,一般要求搭接3厘米。注意刀子的切割。Construction process of  sports PVC floor
Abstract:
1. the ground must be kept dry, dry and free of cracks. 2. the water content of the concrete ground must not exceed 3%. 3. keep the flatness of the ground: the difference between the ground surface of the ground surface and the range of 2m ruler is not more than 3mm. 4. the floor of sports wood, composite wood floor, tile, marble and the floor of marbles can be directly paved.

1. Ground detection
1, the use of temperature and hygrometer to detect temperature and humidity, indoor temperature and surface temperature of 15 degrees centigrade, should not be under 5 or more than 30 degrees C. The relative humidity of the construction should be bounded by 20%-75%.
2. The moisture content of the base is detected by the water content tester, and the water content in the base should be less than 3%.
3, the strength of the base should not be lower than the requirement of the concrete strength C-20, otherwise the suitable self leveling should be adopted to strengthen the strength. 4, the hardness tester test results should be the surface hardness of the base is not less than 1.2 MPa.
5, for the construction of PVC flooring, the roughness of the base should be within the range of 2 meters, the difference between high and low is less than 2 mm, otherwise, the proper self leveling should be used for leveling.
Two, floor pretreatment
1, with more than 1000 Watt floor grinding grinding machine with the appropriate floor of the whole grinding, remove paint, glue and other residues, bulge and loose plots, empty plots must be removed.
2, use an industrial vacuum cleaner with no less than 2000 Watts to clean the ground.
3. For cracks on the floor, stainless steel reinforcement and polyurethane waterproof adhesive can be used to repair the surface of quartz sand.
Three, self leveling construction - bottoming
1. The absorbable base, such as concrete and cement mortar leveling layer, should be treated with a multipurpose interface treatment agent to be diluted by 1:1 ratio to water.
2. Non absorbent base, such as tile, terrazzo, marble, etc., suggest the use of dense type.
The surface treatment agent is used to carry out the bottoming.
3, if the base water content is too high (>3%) and need immediate construction, the epoxy interface treatment agent can be used for bottoming treatment, but the premise is that the moisture content of the base should not exceed 8%.
4, the construction of the interface treatment agent should be uniform, without obvious liquid accumulation. After the surface wind drying of the interface treatment agent, the next step of self leveling construction can be carried out.
Four, self leveling construction - mixing
1, a package of self leveling is poured into a mixing bucket with clear water in accordance with the specified water cement ratio, and the side is dumped and stirred.
2. In order to ensure the uniform mixing of self leveling, the electric drill with high power and low speed must be used to mix with a special agitator.
3, stir to the non - lump uniform slurry, the static and mature for about 3 minutes, and then briefly stirring once.
4, the amount of water added should be strictly in accordance with the water cement ratio (please refer to the corresponding self leveling manual). Too little water can affect liquidity. Too much will reduce the strength after curing.
Five, self leveling construction - laying
1, the self leveling slurry mixing well dumped in the floor construction, it will automatically flow and leveling the ground, if the design thickness is less than or equal to mm, it needs a special tooth scraper scraping.
2, shall be followed for the construction personnel wear special spikes, entering the construction ground, with the self leveling roller for deflation in self leveling the surface gently rolling, mixing in the mixed air release, avoid bubble pits and interface height.
3, after the completion of the construction, please close the scene immediately, no walking within 5 hours, 10 hours to avoid the impact of heavy objects, 24 hours after the laying of PVC floor.
4, in winter construction, the floor should be laid for 48 hours after the construction of self leveling.
5, if the self leveling is required to be polished and polished, it should be carried out after 12 hours of self leveling construction.
Six, floor paving, pre laying and cutting
1, whether it is or should be in the bulk material, the placement of more than 24 hours, the reduction of material memory, temperature consistent with the construction site.
2. Use a special trimming machine to cut and clean the edges of the material.
3, the bulk of laying, between two pieces of material should be close to and no seams.
4, when the rolling material is laid, overlapping cutting should be adopted for the lap of two pieces of material, which is generally required to overlap 3 centimeters. Pay attention to the cutting of a knife.
Seven, floor paving - paste
1, choose appropriate glue and scraping board suitable for PVC floor.
2, tiles, one end of the coil will be folded up. First the Qing Ping sweep and roll back, then on the floor above frictioning. 3, block paving, please send the bulk from the middle to both sides turn up, also will be back after cleaning on the ground and floor glue. 4, different paste in the construction requirements will be different, specifically refer to the corresponding product instructions for construction.
Eight, floor paving - exhaust, rolling
1, after the floor is pasted, the floor surface is pushed and pressed with the soft wood block to smooth and squeeze out the air.
2, then use 50 or 75 kilograms of steel roller evenly roll the floor and timely repair the stitching edge of the edge of the situation.
3, the excess glue on the surface of the floor should be cleaned in time.
