Polyphenyl mortar insulation floor construction technology

Polyphenylene insulation paste cushion Allowable deviation Permissible deviation of the subproject mm Inspection method 1 Surface flatness 5 Use 2m ruler and feeler feeler 2 Elevation + 0, -5 Level gauge and ruler 3 Slope degree 2/1000 Use slope ruler 4 Thickness 1/20 Insulation polystyrene feet (Author: CIMC Construction Group Co., Ltd., Xiangshan Park Management Office) Insulation polystyrene flooring.

2.1 polyphenyl should be used bulky bulk material greater than 18kg/m3 polyphenylene granules, polyphenyl granules loose bulk density of the test, can be used to form a temporary enclosure a 1m3 container or tank, and then after the bag of dry polystyrene weighing Into the pool, when the pool reaches 1m3, we can get the loose density of polyphenylene particles.

2.4 Machines Compulsory mixing tear, rake, plate vibrator, iron roller, stupid container.

The installation of the alloy sub-frame is completed 3.2 The insulation of the heating pipeline through the ground is completed and the pressure test is completed; 3.3 The test pressure of the water pipeline through the ground is completed, the electrical pipeline sweeping is completed; 3.4 All the ground openings are completely closed; 3.5 Covert acceptance of all the ground is completed 3.6 laboratory given the polyphenylene insulation slurry mix ratio.

Basic treatment to find the level of high-elastic level control line Crushing and mixing cement coating layer laying polyphenylene slurry | vibrating and picking | curing 4.2 grass-roots treatment: Before pouring polystyrene insulation mortar cushion, the concrete ± also surface Treatment, remove the loose concrete, mortar, etc. bonded to the base layer, then use a wire brush to treat the cement sizing, and then use a broom to sweep; 4.3 to find the standard high level control line: according to the +500mm level of the wall Elevation line, and then out of the cushion elevation line, and the wall around the pop-up; bathroom slope is also derived from the wall elevation line, and then follow the design slope requirements, at the lowest point to do the lowest point elevation control pier, Afterwards, slopes shall be used to make screeds. Every 1.5m on the floor in the room, the leveling pier shall be wiped out with fine-grained concrete. The elevation of the leveling pier shall be taken out from the elevation line of the wall with a small line; 4.4 Measurement of Polystyrene Thermal Insulation Slurry : Polyphenylene paste insulation ratio of the ratio of weight ratio, the recommended ratio of particles: 4.5 Stir: Add sequence, first add cement, particles, dry mix 1min, then add sand, add water and stir for 2min, Polyphenyl The stirring time of the warm slurry should not be 4.6 The ground floor treatment: Before preparing to spread the benzene insulation slurry, the cleaned floor should be sprinkled with water, and then the cement slurry coating layer should be applied and the water-cement ratio of the cement slurry should be applied. General control in 0.4-0.5, then even watering; 4.7 pavement polyphenyl thermal insulation slurry: the completed concrete shovel with concrete shovel to the grassroots level, and basically flat, usually pavement should be higher than the benchmark line 5~10mm Polyphenylene insulation slurry construction generally do not leave the construction joints, if you must stay, should stay in the doorway and walkway, rub every time you should also brush at the construction joints a layer of cement paste; 4.8 compaction: polystyrene insulation After the slurry pavement is completed, use a vibrator plate and a special wood clapper to compact the pressure and return it to the slurry. Then, use a 2m big bar to scrape the surface. Use a wooden trowel to apply the pressure or compaction. Surfacing on the surface, usually full B for the process control is appropriate in 2h.

4.9 Maintenance: After the polystyrene insulation slurry is poured, the polystyrene insulation slurry must be watered and maintained. When the water is poured, the surface of the concrete should be placed with a pan, and the watering curing time is not less than 3 days. According to the polyphenyl insulation slurry The surface is always wet to control the number of waterings.

Wen / Zeng Xianjin Zhang Shaohua should be poured cement slurry on the surface of the cushion, then the construction of the surface floor. After the construction is completed, the maintenance work on the surface floor must be strengthened, and the ground surface layer should be kept wet for at least 7 days.

5.1 Cracking: The person is too early, the cementing layer is poorly bonded when laying, the ground layer is not clean, and the watering is not enough; 5.2 The strength is low: the mixing ratio is not right, the mixing time is short, the mixing is not uniform, the construction operation time Too long, the person is too early, the press pressure is not true, the conservation time is short or improperly maintained, the wall roots can not handle; 5.3 surface from the layer: on the person early, the surface is not protected on the cart; 5.4 check points: grassroots cleanup With sprinkler, conservation etc.

6.1 Polystyrene thermal insulation slurry raw materials must meet the requirements of the design and construction acceptance standards, the cement must have a factory certificate, retest report, particle factory certificate, retest report, sand retest report, etc.; 6.2 polyphenyl insulation paste pad The material, strength and density of the layer must meet the requirements of the design and construction acceptance standards; 6.3 Polystyrene insulation paste cushion and base layer must be firmly bonded and must not have empty defects such as hollowing, cracking, and loose surface.
