1. Contents of dark column
1.1 the mud of the root of the dark column has been cleaned.
1.2 in order to ensure the location of the dark column reinforcing bar is controlled by the setting frame.
1.3 column stirrup binding
1.3.1 the number of column stirrup is determined according to the drawing, and the first stirrup is set at 30mm at both ends.
1.3.2 draw the position line of the stirrups on the RIPS, and then use the buckle method to bind it from the top down.
1.3.3 the joint of the stirrup should be arranged along the column and the tendon should be arranged with the main tendon vertically and the bandage should be turned in.
1.3.4 the requirement for the binding of dark column and wall bars: the dark column stirrup and the horizontal reinforcement of the wall shall not be more than 20mm, and shall not be together.
2. Wall, dark column and even beam reinforcement
2.1 water and water slurry in the root of the wall has been cleaned up.
2.2 the wall reinforcement has been straightened, and the displacement is too large to be adjusted by 1:6, the first level steel bending hook is in the north, and the non-vertical has been straightened.
2.3 initial requirements
2.3.1 the distance from the first column of the first wall of the dark column is 50mm.
2.3.2 the first horizontal bar of the wall is 50mm.
3.2.3 the first stirrup of the dark column is 50mm from the concrete surface.
2.3.4 the band beam is 50mm from the edge of the dark column.
2.3.5 the string of a connecting beam is 50mm in the column.
2.4 vertical bar and bar connection requirements
2.4.1 the lap length is not less than 47d, and there are three horizontal bars.The binding range is not less than 3 buttons.The wall is 50% staggered, and its staggered distance is no less than that of the adjacent joint.
2.4.2 the wall horizontal section requires that the adjacent lashing joints should be staggered, and the hook installation should be equipped with a double T card or double F card in case the wall reinforcement is offset.
2.5 requirements for vertical ladder bars
2.5.1 steel reinforcing bar with vertical steel bar is adopted to replace the vertical bar.
2.5.2 the top mould is equal to the thickness of the wall of the wall minus 2mm (for example: the length of the top mould of 200mm thick wall should be 198mm).
2.5.3 die steel independence reinforcement to end = the length of the muscle layer + levels diameter 1 mm, (for example: protective layer is 15 mm, horizontal reinforcement for phi 8, the length of 15 + 8-1 = 22 mm) the roots of die steel for 3, mold steel end smooth and good anti-rust paint brush.The height of the installation should be consistent, and the spacing should be accurate.
2.5.4 non-top die bars are horizontal bar diameters on each side.
2.5.5 the number of vertical ladder bars per section of wall is required to be 1m, with each wall 2 or more above, the same elevation is required and the binding is in place.
2.6 level ladder bar requirements
2.6.1 production of short material reinforcement.
2.6.2 horizontal ladder bars are made according to the drawing and meet the bar spacing of the wall. The brick wall is dedicated to the control height and the binding is in place.
2.6.3 when the wall rebar is attached, it is set in the top of the wall template 300mm, and the binding is put in place.
2.7 column spacing frame
2.7.1 make the standard and bind firmly.
2.8 protection layer requirements
2.8.1 columns, walls and beams are made of plastic pads that meet the thickness of the protective layer. The horizontal bars of the wall are 15mm, and the girder is 25mm.
2.8.2 set the spacing of 600mm x 600mm in plum blossom layout.
2.8.3 beam and column reinforcing bars are set on the main reinforcement, and the wall reinforcing bars are set on the horizontal bars of the wall.
2.9 requirements for stirrup
2.9.1 hook must be parallel, hook Angle is 135 °.
2.9.2 the flat part is 10d, and the two lengths are consistent.
2.9.3 the bending core is in accordance with the diameter of the main bar, which is to bind to the main bar to be.
2.9.4 Angle at the same level.
2.9.5 bind firmly (i.e. : not to lose, not to loosen).
2.9.6 The opening of the hoop is set at four corners.
2.9.7 the diameter and spacing of the columns and overbeams are required to meet the design requirements.The spacing is controlled by 5d and 10mm when required.(i.e., more than 22 Φ control according to 10 mm, less than 20 according to the 5 d control Φ).
2.9.8 the straps of the girder are not inclined and evenly spaced. The openings are located on both sides of the upper part.
2.9.9 single band set according to the requirements of drawings, hook is 135 °, the length of the straight 10 d.
2.10 hole and reinforcement requirements: the opening of the wall of the hole wall is required to add a three-sided opening band.Additional holes and reinforcement are required according to the drawing.
2.11 reinforcement of beam reinforcement: the length must meet the requirements of design and specification.
2.12 The main reinforcement of the beam must be located at the four corners of the stirrup, and the pitch of the two rows of main bars is the steel bar spacing. If it is less than or equal to 25mm, the diameter of the bar should be greater than 25mm
