(1) According to the computer simulation, the arc with a radius of more than 50m has a chord length that differs from the corresponding arc length by less than 1.6mm. Therefore, the arc length is controlled by the chord length, and the difference is adjusted by the gap between the 460mm wide plywood.
(2) The curved shear wall and the beam are all longitudinally arranged by 460mm wide plywood vertical vertical die, and the vertical and horizontal spacing of the pull bolts are arranged with a spacing of 460mm.
(3) Firstly trim the side of the 45*95 wooden side with a length of 3m, according to the requirements corresponding to the 3000mm arc, as the horizontal support horizontal main keel, the upper and lower spacing is 300mm; the vertical keel is the same as the double-bolt bolt Layout, that is, the longitudinal spacing is 460mm. The mask is made of 460mm wide plywood (a vertical ply cut from a complete plywood, no scrap).
(4) The horizontal wooden main frame is precisely processed by the woodworking room according to the matching pattern, and numbered, indicating the position of the arc. The shear wall mold and the transverse cofferdam are combined on site in the woodworking room. The processed wood splint is flattened and flattened, and the second varnish is brushed. The curved concrete formwork cuts several 6mm deep gaps on the back with a saw. The gap between the gaps is between 100mm and 150mm, which makes the board natural and round. The goal.
(5) Apply a 2mm thick single-sided tape to the back of the gap between the wood splints, and use 60×l5 wood and wood screws on the back of the template seam strip to tighten with the adjacent 2 plywood to prevent leakage. The bolt holes of the inner template of the clear water wall are formed in the woodworking field, and the position of the outer template is determined according to the position of the bolt holes of the clear concrete formwork. When the bolt is fixed, the end face of the bolt end body is placed close to the template surface.

When the bolt is fixed, the end face of the bolt end body is placed close to the template surface.
(6) The distance between the cofferdams is 300mm, and the outer steel pipe keel @460 of the lateral cofferdam is drawn by CAD. The horizontal and vertical alignment bolts are evenly distributed on each plywood.
(7) The lower part of the formwork and the lower concrete layer must be closely matched. When pouring the floor concrete, level and smear with a water level gauge, and paste 2mmmm thick single-sided tape paper to prevent leakage.
(8) In order to ensure the accurate size of the door and window opening and control the deformation of the concrete pouring, the hole template adopts the built-in clear water template frame, and the outer template is arranged according to the arrangement diagram, and the pulling bolt is uninterrupted at the hole. The template frame is internally arranged with square wood support, and the square wood support is connected with the cofferdam and the row frame by bolts. In the lower part of each window template, several φ5 rows of vent holes are provided.
(9) For the beam arc mold, the woodworking room is directly combined into a template of about 3000 mm according to the mold pattern, and assembled directly at the scene according to the arc situation. Curved shear wall molds are assembled on site.
(10) Wall mould wall bolts are arranged at a distance of 460mm from top to bottom and left and right, and the bottom of the shear wall is 230mm from the root of the shear wall. Φ14 pairs of bolts with a height of 3.0m or less and Φ16 pairs of bolt bolts with a layer height of 3.0m~5.0m, exceeding 5.0m, considering the layering construction, the height of each layer is not more than 5.0m.
