Referring to shown in Figure 1, this cast-in-site concrete arc outer wall body single side formwork job practices, construction sequence is as follows:

Step 1 is provided with built-in fitting 1 on the concrete floor 7 below the circular arc body of wall of not pouring into a mould as yet, earlier the stone bolt lower horizontal is embedded in concrete floor inside in advance, and its top becomes the crooked obliquely concrete floor that also stretches out of 45 degree; Again at stone bolt upper end assembling attaching nut 1.2, outside connecting rod 1.4, pressure beam 1.3 and outer nut 1.5.Built-in fitting 1 distance each other is not more than 300mm, at the Origin And Destination place near one section circular arc body of wall a built-in fitting is set respectively.Stone bolt 1 goes out the place, ground and is 175mm with circular arc metope distance; Going out flooring length is 130mm; Each pre-embedded bolt distance each other is 300mm.

Step 2 is pieced together circular arc wall form 2 in advance;

The assembling method of circular arc wall form 2 is: hole → snap the line of beating dress vertical edges rib on snap the line → blanking on the panel → slab → panel is installed vertical edges rib → snap the line and is installed after perpendicular rib → installations adjuster and the good template of shackle → assembly unit by drawing, regulates template and meet the requirements of radian → template and hang liter and lean against on the piling bin.

Step 3, on-the-spot pre-assembly is also installed unilateral component support 3, and unilateral component support and built-in fitting is fastening, the outside connecting rod 1.4 of built-in fitting is passed the short brace of unilateral component support, to press beam 1.3 and short brace 3.4 to compress by outer nut 1.5 again, thereby the bottom and the concrete floor of unilateral component support 3 will be fixed.Unilateral component support 3 distance each other is not more than 800mm.

The pre-assembly of unilateral component support 3 with mounting method is: brace → be connected with built-in fitting → regulate unilateral component support verticality → installation builder's jack is lacked in the unilateral component support lifting unilateral component support main body → installation bracing piece → installation that puts in place → installs.

Step 4 is connected unilateral component support 3 with circular arc wall form 2;

Step 5, the scene is set up the required scaffold 9(scaffold of unilateral component support and is adopted ∮ 48 * 3.5 steel pipes to set up, this scaffold is reinforced by adding the steel pipe diagonal brace, is stablized by earth anchor pre-buried on floor (∮ 25)), the adjusting base 6 of unilateral component support is fixed with scaffold, after unilateral component support 3 is in place, regulate base 6, suitable for reading until circular arc wall form (2) to the 5mm that inclines within the walls.

Step 6, treat that circular arc wall form, unilateral component support all are in place after, each several part is adjusted, reinforces, is checked;

Step 7 is built circular arc walls concrete 8 between the arc outer wall 13 of circular arc wall form and adjacent architectural;

Step 8, treat that concrete strength reaches code requirement after, carry out mould bases and remove construction.During decentering, earlier loosening support rear support, the loosening embedded part part in back.Hang away one-sided support unilateral component support then, template continues to abut on the metope, temporarily with in the steel pipe support.
