Treatment of beam-wall junction position 8. 1 In order to avoid dislocation of beam-wall formwork junction and affect flatness, the horizontal back purlin on the beam side should reach the junction of beam and wall column formwork at 10cm- 15cm, and the back purlin at the external corner of shear wall side should be cut off at the bottom of beam. 8.2 Beam top and back purlin should be connected with wall top and back purlin to ensure the integrity of beam and wall; The back purlin of shear wall should extend into the beam to the bottom of the plate. 9. Old through-wall screws 9. 1 Old through-wall screws must be set at the bottom of the limb wall column, and the lateral spacing of the screws is? 500mm, each wall column at least two. 9.2 old wall screws should be used? 10 screw for processing. 10, formwork support in slab falling area 10. 1 The battens at the contact surface between formwork and concrete shall be leveled or provided with formwork liner to ensure the formwork removal effect. 10.2 In order to prevent the hanging formwork from being trampled and deformed, the setting position and spacing requirements of the hanging formwork supporting horse stool: from the corner 10cm, the spacing is ≯ 1m, and 1 reinforced horse stool is set on both sides of the formwork joint. 10.3 in order to prevent concrete leakage and facilitate the installation of hanging formwork, all the reserved holes at the lower mouth of hanging formwork shall be provided with flat cover plates. 1 1. Plate thickness control, plate thickness insert brazing, and plate surface stay wire flattening control 1 1. 1. Each board should have at least one board thickness control, which can be made of PVC pipe or precast concrete block with the same height as the board thickness and fixed on the board template with iron wire. After concrete pouring, it is used for the first time. 65438+ 12.2 The supporting members of the slab reinforcement can also adopt concrete piers, plastic piers and newly finished reinforced cushion blocks (recommended). 12.3 concrete polished shoes, avoid leaving footprints and flatten them twice (recommended). 12.4 concrete vibrator (aluminum, light weight), which can further compact coarse aggregate and lift slurry after preliminary leveling (recommended). 13. Vertical structure verticality correction and roof horizontal range recheck 13. 1 Before concrete pouring, after concrete pouring and before initial setting, the verticality of wall column shall be rechecked once and recorded on the floor plan. 13.2 Before the floor reinforcement is bound and before the initial setting after concrete pouring, check the difference between the board surface and the bottom and top of the board, and record it on the plan. 13.3 before concrete pouring, the supervision unit shall recheck and accept the verticality of the wall column template and the levelness difference of the floor and roof, and mark the measurement and recheck data in the original position of the floor plan, and the original records shall be used as the necessary attachment materials for issuing the concrete pouring permit. 14, construction control line (recommended practice) 14. 1 In the structural construction stage, the construction control line will pop up according to the dimensional relationship between the principal axis and the component position. 14.2 The structural stage control line is used to check and recheck the position and verticality of the vertical structure, the masonry stage is used to control the position of the masonry wall and the verticality of the room, and the plastering stage is used to control the verticality, width and depth of the plastering room. 15, diagonal braces (recommended practice) 15. 1 diagonal braces are assembled by steel pipes and top braces; The upper end of the diagonal brace is close to the top row of steel bars of the wall column, and the lower end is close to the floor; The verticality of the wall column is controlled by adjusting the length of the top brace. 15.2 It is forbidden to connect braces with mullions. 16, one-time pouring of lintels (recommended practice) 16. 1 During structural construction, lintels are closed together with structural beams and concrete is poured together. 17, molding quality of concrete structure 17. 1 The concrete structure is dense, and there are no quality defects such as rebar exposure, looseness, slag inclusion, honeycomb, pits and holes. 17.2 The vertical structure has no rotten roots, straight edges and corners, and no damage; The edges and corners of the beam are straight, and the bottom is flat, without distortion and disturbance. 17.3 The floor surface shall be smooth without footprints and cracks, and the bottom of the floor shall be smooth without warping and disturbance. 17.4 stair steps should be smooth, the angle of yin and yang should be straight, the step height should be consistent, and there is no defect. 17.5 floor holes should be closed and protected in time, and the external corners of the conduits on the concrete surface and the vertical structures on the main material transportation channels should be protected.
