  •  Construction scheme of replacing color steel plate for coal conveying trestle in power plant

    1. Operation method, safety and quality control measures

    1.1 main operation scheme

    Construction process arrangement

    Removal of original benzene plate color steel plate, hoisting and transportation of waste plate, base cleaning, hoisting glass fiber cotton color steel plate, wall panel color steel plate installation, roof color steel plate installation, detailed structure treatment, inspection and acceptance.

    1.2 operation steps and methods

    1.2.1 removal of color steel plate

    The wall panels and roof plates on both sides of the trestle are

    Demolition process: top color steel plate removal → wall color steel plate removal → lower opening edge wrapping parts removal → detailed structure treatment.

    1.2.2 color steel plate installation

    Both sides of the deck and the top slab of the trestle

    Installation process: installation of lower edge wrapping part → wall color steel plate installation → roof ridge bottom plate installation → top surface color steel plate installation → roof ridge roof plate installation → detailed structure treatment.

    1.2.2.1 fabrication and inspection of profiled steel sheet

    The raw materials for processing pressed metal plates shall have the quality certificate of the manufacturer. After the forming of profiled metal plate, flashing plate and corner plate, the base plate shall not have cracks. During processing, it is necessary to avoid the defects such as crack spalling of paint mold and exposure of metal substrate.

    The edge of the plate should be flat without burr; the coating should be smooth and clean without visible light, and the color should be uniform and without defects; the surface of profiled steel sheet should be clean, free of oil and sediment, obvious concave convex and wrinkle.

    1.2.2.2 wall color steel plate installation

    According to the construction drawing, the hemming of the lower opening shall be fixed on the purlin, and the lower opening of the hemming part shall be parallel to the lower opening of the trestle. The first color steel tile shall be installed after the hemming parts are installed and fixed. It is very important to install the first color plate, and it should be strictly corrected to avoid large deviation when the plate is installed to the end. The perpendicularity of the first plate of the wall should be strictly corrected to avoid the sawtooth shape of the board end line.

    For every 5 ~ 6 color plates installed, the flatness of both ends of color plates should be checked to ensure the parallel laying of color plates. If there is any error, timely adjustment should be made.

    The self tapping screw is installed every other rib. The screw fixation must start from the laying end of the plate and fix the screws one by one along the same direction as the laying direction of the plate. Do not nail from the opposite direction to the beginning of the plate laying, so as to avoid the accumulated error caused by the plate fixation can not be eliminated, resulting in the formation of a large joint or loose fastening at the plate buckle. It is strictly prohibited to fix the screw in reverse direction. Self tapping screws should be installed with through line and arranged in order to ensure appearance quality.

    The length of single color steel plate on the wall is 3.55m, and there is no need to overlap in the middle. During installation, a person is arranged on the top of the trestle truss to hold the plate, and the person in the cage is responsible for alignment and fixation. In order to ensure the safety of the operators in the cage, the safety belt attached by the personnel working in the cage shall be hung on the trestle truss or purlin, and shall not be hung on the cage. The personnel safety belt working on the top of the trestle truss must be attached to the truss or purlin.

    The installation sequence of the flashing plates on the upper and lower sides of the plastic steel windows should not cause water leakage due to the wrong installation position of the flashing plates. Seal the place, must be in strict accordance with the requirements of sufficient sealing glue, in order to avoid water leakage.

    Danger point:

    1. Falling objects

    2. Accidental fall

    3. Electric shock

    Safety control measures and precautions

    1. Operators are not allowed to throw down any objects. Safety ropes shall be hung when installing nail guns, spanners and stone cutting machines;

    2. The safety belt of operators shall be correctly fastened, and climbing directly from the side of truss is strictly prohibited; operators shall not rest or play with each other on both sides of the trestle; all nodes of the hanging cage shall be inspected before each operation, and shall not be used until it is repaired in case of deformation or damage; anti slip measures shall be taken for construction in rainy days, and operation shall be stopped in case of strong wind above level 6;

    3. The three-phase five wire system must be adopted for construction power supply, and the electrical equipment must be reliably grounded.

    Process quality control measures

    1. After entering the site, the color steel plate shall be inspected and accepted. The deformed color plate shall be corrected, and the color plate that cannot be corrected and recovered shall not be used.

    2. The installation position of the hemming of the lower opening needs to be controlled by hanging line to ensure that the lower opening is straight and beautiful.

    3. The fixed position of rivets shall be controlled with lines to ensure that the fixed points are on the same horizontal line.

    4. The construction of hemming and flashing shall be in strict accordance with the drawings and atlas.

    4.2.2.3 roof color steel plate installation

    After the wall color steel plate is installed and accepted, the top color steel plate can be installed. For the installation method, see page 26 of atlas 01J925-1.

    Laying sequence: the Board shall start from the cornice and proceed from bottom to top. In order to ensure that the roof panel is straight and neat in vertical and horizontal directions, the guy wire at the cornice is parallel to the roof ridge. When laying the first row of cornice boards, the board peak shall be vertical to the cornice line, and shall not be skewed.

    After the installation of the roof ridge bottom plate, the first roof panel shall be installed. The installation of the first roof panel is particularly important. The position of the roof must be controlled and its perpendicularity shall be strictly corrected to prevent the end line of the board from being zigzag.

    After the roof panels on both sides are laid, the roof ridge shall be installed, and the roof ridge shall be followed up with the installation of roof slab. See page 26 of atlas 01J925-1 for ridge roof construction.

    When the roof panel is installed, a full-length safety horizontal rope is set on both sides of the roof to hang the operator's safety belt. The safety belt of the operator is hung on the safety rope to facilitate climbing and ensure the personal safety of the operator.

    Danger point

    1. Falling objects

    2. Accidental fall

    3. Electric shock

    Safety control measures and precautions

    1. Operators are not allowed to throw down any objects. Safety ropes shall be hung when installing nail guns, spanners and stone cutting machines;

    2. The safety belt of operators shall be correctly fastened, and the roof truss shall pass through the vertical ladder, and it is forbidden to climb directly from the side of the truss; the operators shall not rest or play on both sides of the trestle; anti slip measures shall be taken for construction in rainy days, and the operation shall be stopped in case of strong wind above level 6;

    3. The three-phase five wire system must be adopted for construction power supply, and the electrical equipment must be reliably grounded;

    4. After installation, there shall be no surplus materials, rivets and other materials on the roof panel.

    Process quality control measures

    1. After entering the site, the color steel plate shall be inspected and accepted. The deformed color plate shall be corrected, and the color plate that cannot be corrected and recovered shall not be used.

    2. In order to ensure the cornice to be straight, the roof panel must be installed with line control.

    3. The ridge tiles shall be constructed in strict accordance with the drawings and atlas.
