5) In order to prevent slurry leakage from the four corners of column concrete and shear wall, the four corners of column formwork are made into tongue-and-groove flat-fell joints, and the contact surface of formwork at the corner of column and shear wall is increased to prevent slurry leakage from concrete. Column, shear wall template should be installed at the bottom according to the axis and set the sideline, shall not be misplaced. First, the bottom is firmly supported, and the uneven base surface is leveled with 1: 2 water sand, and cleaning holes with a height of 15㎝ are left at the bottom of the formwork and the bottom of the upper beam. Column hoop support and fixture are adopted on the outside of column and shear wall formwork. The lower, middle and upper sections of the column are fastened with steel pipes, the steel pipes of the support frame are fixed with fasteners to prevent position deviation, and the middle section is fixed with clamps. The fixture spacing is generally not less than 500㎝, and the upper and lower fixtures are 20㎝ away from the upper part of column bottom. In general, the height of the column should not be less than 5 to prevent explosion. Shear walls are set with diagonal braces and reinforced with through screws to keep the formwork vertical and stable.
6) Before the formwork of column and shear wall is installed, the basement shall be cleaned, and loose stones and laitance shall be cut, cleaned and rinsed with water. Column and shear wall template should ensure the correct section size and vertical founder. For the installation of column formwork with large cross section, fixtures and supports should be added, and if necessary, the formwork should be tied with screws to prevent the formwork from exploding.
7) The basement of formwork support system adopts φ 48 standard steel pipe with a wall thickness of 3.5㎜, and fasteners are connected with the whole building. The stud spacing is 1000㎜, and the spacing between the stud on the beam side and the beam axis is ≤500. Set two vertical and horizontal tie rods (including a sweeping rod) to ensure the stability of the support. Steel pipes shall be paved with 70×50 wooden back Fang with a spacing of 400 ~ 500 ㎜, and columns shall be padded with wooden blocks. Standard beam and floor formwork support adopts bulk logs, and the diameter of the top of the logs is not less than 6CM. (See the special construction scheme for formwork and support for details)
8) Installation of beam bottom formwork shall ensure accurate positioning of column and shear wall formwork and vertical placement. In order to prevent slurry leakage and formwork expansion caused by the contact between the beam bottom formwork for commercial concrete pouring and the beam side formwork, the expanded beam bottom formwork shall be nailed with 3×4㎝ square timber according to Liang Kuan, and the beam side formwork shall be installed in 3×4㎝ square timber and nailed firmly to prevent formwork expansion and concrete. For beams and slabs with a span of more than 4m, the central bulging in the middle of 4m beams and slabs is required to be 2‰ and less than 5m. When installing, the main beam template should be installed first, and then the secondary beam template should be installed. The secondary beam formwork shall be controlled by the main beam formwork, and the bottom formwork shall be installed first, and then the side formwork shall be erected. The joints of beam bottom formwork and side formwork shall be staggered and supported according to the axis size. When the height of the side formwork is greater than or equal to 800, add φ 10 to reinforce the screw to prevent the side formwork from being deformed by compression. The formwork joints of columns and beams shall be carefully made, tightly spliced and with correct cross-sectional dimensions to prevent slurry leakage, necking and slag inclusion. Beam bottom formwork and side formwork shall be fixed firmly, and the beam bottom formwork shall be nailed with 70×50 square timber to prevent movement and blasting.
9) After the beam bottom formwork and side formwork are installed and fixed, the flat formwork can be laid after checking the axis, elevation and section size.

12) The formwork can be removed only after the concrete strength reaches the formwork removal strength, and the concrete test block removed in the early stage is left at the site. Generally, after the first layer of concrete is poured, the next layer of formwork is removed, so that the formwork removal time is always more than 10 days. The non-bearing side formwork can only be removed after the concrete has a certain strength and can ensure that its surface and edges and corners are not damaged by formwork removal. For non-frame beams with a span of less than 5m, the formwork at the beam bottom can only be removed after the early strength of concrete reaches 95% of the design strength; For load-bearing frame beams with a span of more than 5m and cantilever members with a span of more than 2m, the beam bottom formwork can only be removed after the concrete strength reaches 100% of the design strength. The early formwork removal test blocks retained at the site shall be naturally cured under the same conditions as the components. After the early compressive test, the time of form removal should be determined. Only when the concrete strength reaches the design strength can the concrete structure with the support and formwork removed bear all the service loads. When the effect of construction load is more unfavorable than that of use load, temporary support must be added after accounting. In the process of dismantling the formwork, if the concrete is found to have quality problems that affect the safety of the structure, the dismantling shall be suspended until it is processed. In the process of form removal, attention should be paid to protecting concrete members to prevent concrete members from being artificially damaged due to form removal. After the formwork is removed, it should be cleaned, stacked and corrected in time, and the release agent should be painted to ensure the smooth and flat surface of the reused concrete.
