Construction should be required to carry out the requirements to be paved stone crane strengthening material, mold powder should paving direction, sequentially stacked and use a variety of professional construction tools and crane stone mold, it should also be in good working condition. 2, according to the ratio of the concrete floor of the requirements for various levels of preparation. Climate during the construction quality of construction has a large degree of influence, Choi Ping stone construction crane should avoid rain, snow, wind and freezing weather, day and night, where large temperature at night should be prohibited construction. Good construction environment to ensure the quality of construction, crane stone Choi Ping construction should be avoided with other construction work force cross construction, if necessary, be taken to deal with the construction site closures. 3, construction of concrete according to the construction drawings and design requirements, the thickness of the concrete must be consistent, grassroots must be 5cm or more 5cm basis. 4, expansion joints must be set and within 24-36 hours to complete the laying of concrete in accordance with the design requirements, spaced at not more than 4 m, depth of expansion joints is generally about two-thirds of the concrete floor. 5, the concrete surface should match the length of the class paving stone Choi Ping pavement construction crane, reasonable coordination. Day (by ten hours) must be controlled in the construction area 200m2 classes. Otherwise it will directly affect the quality of construction. 6, surface treatment of concrete surface layer must be designed in accordance with the provisions and requirements, the surface must reach the required flatness, cross slope and width. The quality of concrete in the same project must be consistent, so that the consistency of the final overall effect is very important. 7, using a crane stone smooth concrete surface professional tools and make the corner. 8, crane stone to strengthen the material may agglomerate in transit, we must break with both hands to strengthen the material. 9. Wait for the surface layer of the concrete surface free water dispersed, in order to use the crane Stone expected to strengthen and spread the way of concrete covering the surface evenly, the amount of 35 kg / 10 m2. 10, expected to strengthen the sow must be in two passes, the first pass around about 2/3 of the amount of sowing, sow a second time about the amount of about 1/3. Each crane must be sown once a professional rock smooth spatula to eat into the reinforcing material and cover the entire concrete surface, we must wait to use a large spatula after strengthening material fully wet. 11, in the part that the place needed to strengthen the material necessary to make up after a large crane stone color floor steel trowel must make a final smooth and glossy treatment used up large spatula. 12, while seeding expected to strengthen in strict accordance with the construction crane stone Choi Ping process requirements, do not wipe too shovel concrete surface, which causes the surface of the water and reduce the coloring. 13. The absolute prohibition on the surface layer of concrete sow sprinkler expected to strengthen, which will lead to inconsistent color. 14, expected to strengthen in the second time to sow and harvest smooth light after the end of the crane stone mold powder must immediately evenly spreading the concrete surface with a large trowel smooth after the dosage is generally 2.0 kg / 10 m2. Not using the release material on the prohibition of the use of a crane stone mold. 15, to be expected to strengthen and mold powder together before but not completely solidified, which can use the crane stone imprinting mold forming. To advance research and develop mold arrangement and the position and orientation put up to ensure the integrity of the pattern. The first piece of mold loft pattern along the reference line laying, and pressed into the vertical concrete. Construction can stand on molding, the body's own weight is sufficient to enable a mold to form the concrete surface texture, you can use the crane stone mold, if necessary, the special tamper vertically pressed into the mold within the working surface to better pressure a clear pattern realistic. Master die time is very important, too wet or too dry concrete surface will affect the final design and effect. 16, must be arranged between the compact crane stone mold to prevent the emergence of the double-slit. Pressure must be checked over the place from the mold and after appropriate repair process. 17, according to the reference line after press molding, mold quickly removed and methodically complete sequence of all the concrete surface pressure. You have encountered a wall, corner or other irregularities If the construction, you can use the crane corner stone molding (soft mode), but when used to pay attention to coherence and coordination with the overall pattern. 18, and corner molding mold can be reused, but must be supplied with adequate quantities of mold (usually a set of 4 to 6), in order to improve construction efficiency. 19, concrete surface strength of 70% of the design strength (under most weather was the third day after the die construction), you can use to clean the floor, flushing Do not wash away all the stripping powder can retain 30 about% concrete surface stripping powder. Washing should be done by the person responsible for a reasonable grasp of processing time and pressure of the water when flushing it to the final effect pattern is also crucial. In order to maintain clean surroundings, but also to clear out of the concrete surface with a soft broom releasing material. 20, can be used if necessary, about 5% dilute hydrochloric acid wash. 21, after the total dry concrete surface must be sprayed over 30 percent on the second floor crane stone color protection agents, the dosage is generally about 2 kg / 10 m2. We have to wait until all of the first pass of the protective agent to coat the second time after drying protective agent. Protective agents can brush or spray Pentong first pass from west to east (or north to south), the second time from north to south (or from west to east), brushing twice staggered to ensure uniform brushing. 22, after construction crane Choi Ping pavement stone conservation does not require watering, but before acceptance of delivery must make the necessary protection. In order to make the crane stone Choi Ping achieve the best results, it should strictly follow with the main points: 1, the ratio of the concrete structure is not less than C25. 2, shall not be mixed with concrete admixtures containing chloride and calcium oxide or calcium oxide product. 3. The maximum aggregate particles should not exceed 10 mm. 4, concrete air content control at around 6%. 5, in order to improve the crack resistance of concrete, fatigue resistance and impact resistance, it is recommended adding the appropriate steel fibers, glass fibers and polypropylene fibers. 6, the surface layer of concrete paving length class should be coordinated with reasonable construction schedule Crane Choi Ping of stone. In general, the first day should be controlled at 150 m2 / shift, from the next day may be increased to 200 m2 / shift. Especially with the rainy season, the construction length should be controlled in the winter. 7, correctly grasp the frequency, amplitude level in order to avoid artificial concrete from rare phenomenon occurs. 8, strictly control the flatness, cross slope and width, and so on. 9, after laying concrete water should be prohibited. 10, longitudinal seam, shrinking and cutting construction joints and expansion joints should be completed within 48 hours, seam depth of not less than 1/3 of concrete thickness, kerf width should be between the 5-10mm. 11, if the filling material is generally recommended to use low modulus polyurethane and polysulfide rubber-like ointment caulking caulk. 12, transport, paving, vibration, and other processes do face concrete mixture should be close convergence, shortening the process time interval, reducing heat loss.
