<input id="uauy4"></input> Guangzhou Steel curtain wall construction and process all-glass structures
Installation of Guangzhou Steel full glass curtain wall is more than one joint construction trades, a very complex process, and the operation also requires very fine, requires teamwork team. But it also has a close relationship with the construction schedule of other sub-projects. To make the construction and installation of steel curtain wall smoothly, the project must be based on the actual situation, compile the individual construction organization design, and confirmed by the general contracting unit.
Project started preparatory work
Technical data collection
On-site data collection and civil design of civil structure size measurements. Because there may be some fluctuation civil construction, the actual size is not always in line with the design drawings. Full glass curtain wall on the civil structures related to the higher size requirements. So before the site must be designed to measure, obtain first-hand information and data. And then to draw the curtain separating practical view of the requirements of owners. For door entrance of the site, also must make automatic revolving door, full glass door unit with the glass curtain wall on the door and the door of a reliable shut. But also need to meet requirements for the installation and maintenance of automatic revolving door.
Design and construction plan was finalized
Design and construction plan was finalized. When glass curtain wall design partition, in addition to considering a uniform aesthetic appearance, it should also be taken to minimize the glass specification models. Because all kinds of outdoor architectural design are not the same, to have a large outdoor canopy, driving ramps and other projects, more attention should coordinate the overall construction schedule and order and prevent the construction and other outdoor facilities, the impact of walking crane and glass curtain wall installation. Before the formal construction, but also to deal with the scope of the construction site be flattened infill, good site clean-up, to ensure the smooth running crane.
Prepare materials and mechanical equipment
The main material quality inspection
(1) glass sizes are correct, with particular attention to check the glass during storage and transportation process, whether the damage found to have cracks, chipping the glass must not be installed, and shall immediately notify the reprocessing plant supplement soon as possible.
Material (2) structural metal member meets the design requirements, whether straight member, processed size, accuracy, hole location meets the design requirements. Good anti-rust paint to brush first, to all the member number clearly marked.
The main construction equipment inspection
(1) glass lifting and transportation machinery and equipment inspection, especially for crane operating system and electric chuck performance checks.
(2) Check the performance of a variety of power and hand tools.
(3) embedded parts location and design of the position deviation should not exceed 20mm.
Scaffolding
Due to the different needs of the construction program, construction scaffolding structures must meet different requirements.
(1) discharge line and production load-bearing steel frame, should be set up on both sides of the glass curtain wall surface, to facilitate workers, such as welding and installation work at different positions.
(2) When installing the glass curtain wall should be built on the inside of the curtain wall. To facilitate the lifting obliquely inserted into the glass does not touch the scaffolding, but also make the upper and lower parts of the standing scaffolding workers can easily hold the hand sucker can assist crane glass exact place.
(3) the glass in place after dispensing and cleaning phase, then the need to build a separate row in the outdoor scaffolding, due to the large area of continuous full glass curtain wall, unable to communicate with the outdoor scaffolding then pull the main structure, so pay special attention to the scaffolding support and stable, can land anchors, rope and pull with a bracing strut connection. Construction of each operation to be laying layer height scaffold boards, have a top rail, scaffold boards use wire fixation. In the construction and dismantling of the scaffolding to be extra careful not to throw down throw and steel fasteners from a height, to prevent damage to the glass.
Guangzhou Steel curtain wall installation
Guangzhou Steel curtain wall installation steps roughly as follows:
1. actinomycetes positioning;
2. The upper portion of the load-bearing steel structure installation;
3. The lower portion of the side frame and installation;
4. glass in place.
5. Note sealant;
6. Surface cleaning and inspection;
Maintenance and repair
At present, all-glass curtain wall maintenance and repair of the owners have not been enough attention. Now full glass curtain wall material used has a certain validity period should be observed regularly and maintained in normal use, so after Labor Exchange acceptance, and use of best developed curtain wall maintenance and repair program, and signed a contract with the company.
