Sun canopy construction process
First, the construction method
1, the construction sequence
Measure payoffs - install the sun roof roof frame - adjust, level, fix the sun board ceiling main skeleton - install the leveling sun board ceiling sub skeleton - install the sun board outer layer - glue, install the bead - install the sun
Light board inner layer - glue, install the layering - adjust and deal with the detail of the outside of the sun roof
2, the main construction process
(1) Stretching line: According to the height of the drawing, the size of the ceiling of the sun board and the measured center line, pop up the skeleton line of the sun board ceiling.
(2) Embedded parts: According to the location of the main frame of the sun deck ceiling in the elevation control line, check whether the elevation of the hole countertops meets the design requirements. If there is any difference, the cement mortar should be cut or used with high-strength cement mortar.
Leveling treatment, after reaching the strength, according to the deepening of the design node details of the embedded steel plate size to release the expansion bolt position line, and then drill the expansion bolt, install the steel plate and bulge bolt fixed. Then the main bone
Frame III) L line cast on the embedded steel plate.
(3) Install the main skeleton: According to the pop-up position of the main frame of the sun roof, first install the middle part of the two ends, the method: after the 60mm*40mm*3mm square steel skeleton frame is assembled on the roof,
Place the manpower on the position line, hang it vertically with a wire hanger, temporarily fix it in the middle and weld it with the embedded steel plate. After the main skeletons at both ends are in place, pull the middle and both sides by 1500mm height (from the plate
After the three longitudinal lines pass through, they are installed one by one until the other end is completed.
(4) Installation of sub-skeleton: After installation and fixation of the main framework of the sun board ceiling, install the 60mm*40mm*3mm square steel secondary skeleton of the sun roof, and adjust the position, after leveling, welding with the main skeleton.
fixed. When installing the sun board, place a dampproof agent.
(5) Install the outer sun panel: In accordance with the deepening design layout position, the sun panel with suitable size will be prepared for installation. After installation, the edge, longitudinal seam, and transverse seam of the sun panel will be on the + line.
(6) Applying glue and installing a bead: After fully checking the installation quality of the outer sun board, install the outer sun board while playing the weather resistant glue, and then install the special aluminum alloy bead. Screws for installing the batten
The distance and location must meet the requirements of the drawings.
(7) Install the inner sun board: According to the position of the drawing, prepare the sun board of suitable size for installation. When installing, lower the upper floor board and clean it with a white towel. At the same time, in the inner layer and the light
After the board is wiped clean, it is allowed to be installed, so as to avoid the interlayer contamination from cleaning and affect the macro effect.
(8) Applying glue and installing a bead: After fully checking the installation quality of the inner sun board, change the installation of the inner sun board, play the weatherproof glue, and install a special aluminum alloy bead. Batten screw spacing and position
Set must meet the requirements of the drawings.
(9) After the sun panel is fully installed, the sun panel must be applied around the outside of the ceiling. The shelter can only be removed after all the external walls have been closed. Protective Shed
The scaffolding must be removed and the finished product must be protected. Anti-II: The finished product is damaged.
Second, quality standards and quality assurance measures
1. The construction and installation quality of the steel frame structure of this project shall be carried out in accordance with the Standard for Construction and Acceptance of Steel Structure (GB50205-96).
2. Square steel main skeleton and steel components should be stacked according to the classification, type, and mounting order, so as to facilitate access; stacking components should not be overlapped; when stacking arc square steel skeleton (truss), the lower pad should be placed small
Article.
3, Fang Gangfeng must check the geometric dimensions before the installation of the framework, the weld quality, screw hole position, etc. to conduct a comprehensive inspection, in full compliance with the design requirements before installation.
4, the sun board cutting and transportation must ensure quality. Special attention should be paid to the end of both ends of the sun panel to ensure no damage and to avoid air pollution.
5, the steel skeleton must be transported with care, ensure no collision, long-distance transport of the sun plate must be packed in a small box.
Third, safety and fire measures
1. In order to enter the site of site T, the safety operation regulations must be strictly observed.
2. High-altitude workers must fasten their seat belts. They should be placed in T-bags at their hands, and high-altitude operations must not be carried away.
3, feet in the frame must be erected in accordance with regulations, the construction of regular inspection of the foot on the shelf stability, construction workers should go up and down from the ladder.
4, welders and special types of work permit holders, and set aside to see the fire.
5, on-site fire prevention personnel management, and set up special fire appliances.
Fourth, product protection
1, the sun board at both ends of the head to prevent damage, run out of air pollution caused by the inner wall to add a layer of protective film.
2. Skeletons should be placed strictly before construction of the skeleton to prevent deformation.
3, the sun board in the installation process to prevent collision, scratches.
