for those used before, please refer to

(1) technical preparation

1. Measuring and setting-out: according to the axis control line and the building elevation line uniformly measured in the decoration engineering stage, hang them on the anti-beam around the reserved hole on the roof of the solar panel with a wire pendant, and pop up the central line of the solar panel ceiling, at the same time, lead the elevation to the outside of the anti-beam around the reserved hole on the roof, and play the elevation control line. Check the structural deviation according to the deepening design size as the basis for deepening design.

2. deepening design: according to the size and requirements of the design and construction drawing, the layout design and node detail size design are carried out in combination with the field measurement, and the layout principle is to symmetrically arrange the boards from the middle to the two ends.

(II) Material preparation

1.16mm. and 2mm thick honeycomb panels (sunlight panels).

2. Arc galvanized square steel skeleton.

3. rubber strip.

4. aluminum buckle seam cover plate.

5. aluminum plate closing.

6.6mm×6mm×3mm square steel pipe (galvanized).

(III) Preparation of site construction conditions

1. Set up a full-house scaffold with a steel pipe rack on the floor where the sun panel ceiling is located, and set it up in a ladder shape according to the arc-shaped sun panel ceiling, and lay scaffolding, about 17mm from the top. Attention should be paid to the protection of finished products of installed automatic walkways.

III. Construction methods

(1) Construction sequence

Measuring and setting out → Installing the main framework of the solar panel ceiling → Adjusting, leveling and fixing the main framework of the solar panel ceiling → Installing the sub-framework of the leveling solar panel ceiling → Installing the outer layer of the solar panel → Glueing and installing battens → Installing the inner layer of the solar panel ceiling → Glueing and installing battens → Externally.

(II) Main construction technology

1. Sprinkle line: according to the elevation of the drawing, the position and size of the solar panel ceiling and the measured center line, the position line of the main skeleton of the solar panel ceiling will pop up.

2. embedded parts: according to the position of the main framework of the sun panel ceiling of the elevation control line, check whether the elevation of the upper surface of the anti-beam at the entrance meets the design requirements. If there is any difference, chisel it or level it with high-strength cement mortar. After reaching the strength, release the position line of the expansion bolt according to the size of the embedded steel plate in the detailed drawing of the deepening design node, then drill and place the expansion bolt, and install the steel plate and fix it with the expansion bolt. Then cast the center line of the main skeleton onto the embedded steel plate.

3. Installation of the main skeleton: according to the position line of the main skeleton of the pop-up solar panel ceiling, install the two ends first and then the middle part. The method: after assembling the main skeleton of 6mm×6mm×3mm square steel pipe (galvanized) on the roof, place it on the position line manually, hang the vertical surface with wires, and weld it with the embedded steel plate after temporary fixing in the middle. After the main skeleton at both ends is installed, pull three longitudinal wires with a height of 15mm in the middle and on both sides (measured upward from the supports at both ends of the steel plate), and then install them one by one from one end to the other until they are all completed.

4. Installation of sub-frame: After the main frame of the solar panel ceiling is installed and fixed, install the 6mm×6mm×3mm square steel sub-frame of the solar panel ceiling, adjust the position, and after leveling, weld and fix it with the main frame. When installing the sun board, put moisture-proof agent.

5. Installation of the outer solar panel: according to the layout position of the deepening design, install the outer solar panel with a thickness of 2mm, and the edges, longitudinal seams and transverse seams of the solar panel will be in a line after installation.

6. Glue and install batten: After fully checking the installation quality of the outer solar panel, install the outer solar panel, weather-resistant glue and then install the special aluminum alloy batten.

7. Installation of inner-layer solar panels: according to the position in the drawing, install the inner-layer solar panels with a thickness of 16mm, and clean the bottom of the upper-layer solar panels with a white towel during installation. At the same time, clean the inner-layer solar panels before installation, so as to avoid the interlayer pollution that cannot be cleaned and affect the macro effect.

8. Glue and install battens: After fully checking the installation quality of the inner solar panel, install the inner solar panel, weather-resistant glue and install special aluminum alloy battens. The screw spacing and position of the batten must meet the requirements of the drawings.

9. after all the sun panels are installed, the perimeter of the sun panel ceiling eaves must also be constructed according to the nodes in the drawings. The protective shed can only be removed after the eaves are completely closed (including glass curtain gables). Protective shed must be carried out in accordance with the requirements of scaffold removal, and the finished product should be protected to prevent the finished product from being broken.

iv. quality standards and quality assurance measures

1. the fabrication and installation quality of the curved steel frame structure of this project shall be implemented in accordance with the code for construction and acceptance of steel structures (GB525-96).

2. The main skeleton and steel members of arc square steel shall be stacked according to the classification, model and installation order, so as to facilitate access, and the members shall not be overlapped; When stacking the curved square steel skeleton (roof truss), the lower part should be padded with battens.

3. Before installing the main skeleton of square steel, it is necessary to check the geometric dimensions, conduct a comprehensive inspection on the weld quality and screw hole position, and install it only after it completely meets the design requirements.

4. The cutting and transportation of the sunlight board must ensure the quality. Pay special attention to the ends of the solar panel to ensure that it is not damaged and avoid air pollution inside the honeycomb.

5. The arc-shaped steel skeleton must be handled with care to ensure no collision, and the long-distance transportation of solar panels must be packed in wooden cases.

V. Safety fire control measures

1. You must strictly abide by the safety operation procedures when entering the construction site.

2. Workers working high above the ground must fasten their seat belts, put the tools at hand in the tool bag, and do not throw tools when working high above the ground.

3. Scaffolding must be erected according to regulations, and the stability of scaffolding should be checked regularly during construction. Construction personnel should walk up and down the stairs.

4. welders and special types of work should hold relevant certificates, and designated persons should watch the fire. Special attention should be paid to the installed automatic trails, and the upper part of the shed must be covered with thin iron sheets.

5. Fire prevention on site is managed by special personnel, and special fire-fighting appliances are set up.

VI. Protection of finished products

1. In order to prevent damage to the ends of the solar panel, a thick protective film is attached to the inner wall of the honeycomb due to air leakage.

2. Before construction, the curved skeleton should be strictly packed neatly to prevent deformation.

3. The sun panel should be protected from collision and scratch during installation.

1. PC sunshine board specifications:

thickness: 4mm, 6mm, 8mm, 1mm

length: standard 6m. The size can also be customized according to customer requirements.

width: standard size 21mm, maximum size 216mm

color: transparent, lake blue, green, brown, milky white, etc.

2. Just use a single layer of steel tile with a thickness of .5, and use 12 circular tubes with a diameter of 1 to make columns, which are highly needed. The columns should be tall and short with a waviness of .5m-.15m..
