A, concrete engineering
1. Before concrete pouring, the foot of the wall column should be blocked in advance (the carpenter of the project department should be responsible for it in advance if it exceeds 20mm) to avoid root rot. When pouring concrete, commercial concrete shall not be added with water at will. According to different concrete grades, the wall column is poured first, and then the beam slab is poured. When pouring beam slab concrete, it should be vibrated carefully, and there should be no honeycomb, pits and vibration leakage. Strictly control the leveling elevation of concrete, and control the surface smoothness according to the 500-line and technical disclosure. The surface layer should be even and flat, and the plastic film should be covered completely. During the construction in spring and summer, after concrete pouring 12 hours, water shall be sprayed in time for maintenance for not less than 7 days, and it shall be guaranteed for not less than 3 times every day. The fine is 100 yuan each time, and 500 yuan will be fined for not sprinkling water for one day.
2. When pouring concrete, the ground ash should be cleaned and used in time, so as to clear the material after work. If the material is wasted, the material loss will be doubly punished.
3. Before concrete pouring, the warehouse should be cleaned, the wooden pattern should be wetted with water, and the beam-column summer-planting (including wall and stigma) should be cleaned. When pouring, the same grade of bonding slurry (column, wall thickness 50- 100MM) should be used, and the construction joints should be left in the position allowed by the design, designated by technicians, sealed with formwork and kept straight, and the surface of column and plate should be controlled according to the elevation. The concrete shall be vibrated and compacted, and there shall be no honeycomb pits exceeding 200 square centimeters, so as to prevent vibration leakage and slag inclusion (including rotten feet of column feet).
4. When pouring concrete, it is forbidden to trample the steel bar at will to ensure that the steel bar configuration meets the design requirements.
Second, the steel engineering
1. The construction must be carried out in strict accordance with the design drawings.

Gaps exceeding 5mm shall be glued with double-sided adhesive tape, and XB roof shall be glued with adhesive tape. Every time double-sided tape and transparent tape are found, there will be flower corners, lace and pits after concrete pouring. According to the pop-up 300 control lines on each floor, the position of each beam bottom is strictly checked, and the allowable deviation is controlled within 5 mm. 2. According to the pop-up 500mm line structure and the construction drawings of each floor, the template elevation is strictly controlled, and the surface flatness of each room template is controlled within 5 mm, and it is forbidden to exceed10 mm; 3. Strictly check the verticality, flatness and axial displacement of each wall column according to the 300mm pop-up control line on each floor, so as to enhance the stability of the frame body and avoid the displacement and deformation of the wall forming concrete.
2. When the formwork is installed, the construction must be standardized according to the requirements of drawings, the axis and formwork sideline should be put away, and the level should be set to control the elevation. The templates used should be coated with isolation agent and stacked in different categories. After the acceptance of reinforcement, formwork installation shall be carried out. It is required that the joints should be tight and not leak slurry, the axis and elevation should conform to the regulations, the deviation of beam-column joints should not be too large, the thickness of concrete walls should be consistent, the formwork should be vertical, and the top pulling should be firm and reliable. For beams and slabs with a span of more than 4M, bulging should be carried out according to regulations to prevent uneven stress, distortion and scratches on the middle part of the beam. The embedded parts and holes fixed on the template shall not be missed and shall be installed firmly. When the concrete label of beam slab and wall column is inconsistent, the junction of beam and wall column shall be bound with steel wire mesh according to regulations to prevent concrete from leaking and affecting the quality of concrete pouring. If it is leaked, it will be punished. Installed templates must be self-checked, and submitted to the project department and supervision for inspection and acceptance after passing the inspection. When pouring concrete, there should be someone to look after the warehouse in case of emergency.
3. Form removal: When the bottom form and its support are removed, the concrete strength should meet the design requirements, and it can only be removed with the permission of the builder. When the formwork is dismantled at an altitude of more than 4M, the formwork materials shall not fall freely, and the formwork materials shall not be pried off in a large area. After the template materials are removed, they must be cleaned up, coated with release agent, and stacked in categories. The scattered parts should be stored in boxes and bags.
Fourth, masonry engineering
1. The mixing and preparation of mortar should be carried out in strict accordance with the mixture ratio, and the sand must be sieved before use. Mortar should be used when mixing. Cement mortar and cement mixed mortar should be used within 3 hours and 4 hours respectively. When the temperature exceeds 30 degrees, it should be used within 2 hours and 3 hours respectively.
2. Bricks (blocks) should be watered and wetted 0-2 days before use. Masonry quality requirements are horizontal, vertical, full mortar, correct assembly and reliable summer-planting. The corner and junction of masonry should be built at the same time, and the temporary discontinuity that cannot be built at the same time and must be preserved should be built into an oblique if, and the horizontal projection length of the oblique if should not be less than two-thirds of the height; Vertical mortar joint can not have open joint, blind joint and false joint; The mortar plumpness of horizontal mortar joint is not less than 80%, and the mortar joint thickness is controlled within 10mm; Axis displacement and verticality shall not exceed the specifications.
