1. construction scope: the reinforcement binding construction from the basement wall column to the top floor of this project.
2. Quality requirements: All sub-projects have passed the first acceptance, and civilized construction within their respective scope has been completed.
Third, the specific quality disclosure:
1, column, column stirrup @ 100, each column is 29, the first hoop is 50mm away from the ground (board surface), the row spacing of main reinforcement in the column is relatively uniform, with hooks, and every other stirrup is placed, with plum blossom layout. Tie it up. The main reinforcement of the column must be tied with stirrups at the internal corner, and the rest parts are the same. Column reinforcement must have positioning stirrups 500mm away from the board surface and must be bound with the main reinforcement. The protective layer of the column is 20mm, and the protective layer must be padded before binding the beam. When the beam gluten enters the column, it must be bound with the main reinforcement of the column. When the horizontal flashing rod of the wall enters the column, it must be bound with the main reinforcement of the column at least three times. After each layer of pay-off, it is necessary to check that the column reinforcement is busy or the protective layer is large, or the row spacing of the main reinforcement is uneven, and it should be rectified and adjusted in time before binding. Misuse or substitution of stirrups is strictly prohibited. Beam-column joints must have encryption hoops @ 100.
2. The wall and horizontal bar @200*** 15, and the hook @600 is arranged in a plum blossom shape. Steel dowel @200. The lap joint of 42d is about 5 10, and the lap joint must be tied in three times. The joints are staggered by 50%, and the wall must be full. It is forbidden to tie or loosen the horizontal bar and the concealed column bar to the corner. The first and last root cutting bars are 50mm away from the embedded column, the wall protection layer is 20mm, and the cushion block is @800, which is arranged in a plum blossom shape, and it is placed and fastened from the second horizontal bar. Misuse or substitution of horizontal steel bars and steel dowel bars is strictly prohibited. Each wall must be provided with a locating strip 500 away from the board surface.
3. The main reinforcement of beam and coupling beam is bent, and it should be placed along the bend when binding to ensure the section size of beam. Beam stirrup @ 100 There are three encryption hoops @50 at both ends near the column edge, and the frame stirrup is 150. Beam anchorage 35d, protective layer 25. When tying, pay attention to the gluten must be cross-tied, and it is forbidden to tie or loosen it. The reinforcement at the hole left by the coupling beam cannot be omitted. The beam hoop at the opening should not be misused. The spacing between the main bars of beams shall be uniform, and the spacing between the second row of bars and the first row of bars shall not exceed 50 mm Each beam shall be constructed in strict accordance with the size, specification and quantity of the bill of materials, and the anchorage at both ends shall be consistent, and one end shall not be long and the other end shall not be short. Add "2 Ф16" length 1500 to the cylindrical wall of each door opening.
4. The spacing, size, shape and specifications of the plate and the steel bars at the bottom of the plate shall be bound in strict accordance with the drawings and bill of materials. The anchorage length of each plate in bucket gables, elevator shaft walls, etc. It should be 40 days, and the anchorage in other places should extend to the center line of the beam, the reinforcement of each hole, the reinforcement at the bottom of the plate, the hidden beam in the bathroom and the hidden beam in the kitchen. Should be placed according to the size of the bill of materials and drawings. Misuse, misuse or substitution is strictly prohibited. Plate gluten should be added with positioning reinforcement at the wall, and fastened with gluten and steel dowel. Stirrups should be distinguished in height according to different colors, 7mm colorless stirrups, 100 thick plate 8mm yellow, 120 thick plate 9mm red, 130 thick plate, 10mm black. The gluten of floor slab bottom reinforcement must be fully bound in the shape of eight, and binding or loosening is not allowed. Floor cover 15mm, cushion block @800. It is forbidden to pour the redundant cushion blocks into the beam or wall. The stirrup of plate beam @ 150 is determined according to the height of each block and shall not be used at will. Before pouring concrete, the board surface must be thoroughly inspected. If there is any leakage pad, leakage or less misplaced reinforcement, it must be remedied in time so as not to affect the construction period.
Four. Schedule requirements: contracting teams and individuals must obey the command and management of the project, be careful and complete the plan with good quality and quantity on time according to the schedule requirements of the project department. Shall not violate the company's rules and regulations. Listen to the arrangement and mobilization of the foreman, and Qi Xin will work together to complete the reinforcement construction task of this project.
