Steel structure encased in glass curtain wall construction and process

Steel structure installation of full glass curtain wall construction is more than one joint construction trades, process is very complex, and the operation also requires very fine, demand tacit team. Together they have close links with the construction progress of programs of other sub-project. In order to make the construction and installation of the steel structure of the smooth walls, it must be based on the actual situation of the project, preparation of a good individual Hainan steel construction organization design, and confirmed by the general contracting unit.

The first is the project started preparatory work

Technical data collection

Site civil engineering design data collection and civil construction scale measurements. Because there may be some fluctuation civil construction, not necessarily fit the actual scale and design drawings. Full glass curtain wall construction of civil engineering higher correlation dimension requirements. So before the measurement site must be designed to obtain first-hand information and data. And then to draw realistic view of a curtain separates the requirements of owners. For the entrance door of the site, you must also take the initiative and manufacturing revolving door, the unit with full glass door, the glass curtain wall on the door and the door of a reliable shut. Together also need to take the initiative to meet the installation and maintenance requirements of the revolving door.

Hainan steel structure design and construction plan was finalized

Design and construction plan was finalized. When the design of the glass curtain wall separated, except to think about the shape of uniform appearance, we must also pay attention to try to cut glass of standard models. Because the construction of various types of outdoor design are different, to have a large outdoor canopy, driving ramps and other projects, more attention should coordinate the overall construction sequence and schedule, to avoid because of construction and other outdoor facilities, the impact of walking and glass curtain wall crane installation. Before the formal construction, but also to deal with a range of places construction leveling infill, good place to clean up, to ensure the smooth running crane.

Further information and mechanical equipment is ready

The main data quality checks

(1) glass scale is not the correct specification, with particular attention to check the glass in storage, whether the damage during transport, a crack is found, glass chipping must not be installed, and shall immediately notify the plant quickly reworked to compensate.

(2) Material metal structural member is not fit the design requirements, member is not straight, the processing scale, precision, hole orientation is not meet the design requirements. To a good first anti-rust paint brush, all member number must be labeled clearly.

Main construction equipment inspection

(1) Glass lifting and transportation machinery and equipment inspection, especially for crane operating systems and electric sucker function tests.

(2) all kinds of electric and manual things function tests.

(3) the orientation and design of embedded parts bearing error should not exceed 20mm.

Scaffolding

Because of the different needs of the construction program, the construction scaffolding structures must meet different requirements.

(1) discharge lines and manufacturing bearing steel structure stent, should build on both sides of the wall surface of the glass, to facilitate workers in different directions, such as welding and installation work carried out.

(2) When installing the glass curtain wall, should be set up inside the walls of. To facilitate the lifting obliquely inserted into the glass does not touch the scaffolding, but also make standing up and down in various parts of the scaffold 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, because the whole glass curtain wall series of larger, the outdoor scaffolding was unable to pull the body structure then, so pay special attention to scaffolding support and stable, able to land anchors, rope and pull with a bracing strut connection. Construction height of each operator should lay out scaffold boards, top to have fences, scaffold boards use wire fixation. In the construction and dismantling of scaffolding to be extra careful not to throw steel and fasteners throw down from a height, to avoid damage to the glass.

Then is an important project: steel construction curtain wall installation.

Steel structure wall installation steps roughly as follows:

1. actinomycetes positioning;

2. The upper part of the load-bearing steel structure installation;

3. The lower portion of the side frame installation;

4. glass in place.

5. Note sealant;

6. clean appearance and acceptance;

After the End is the maintenance and repair

Currently, the maintenance and repair of all-glass curtain wall has not been enough attention owners. Information is now full glass curtain wall used has a certain validity, but also regular observation and maintenance in normal use, so after Labor Exchange acceptance, and use is best to formulate curtain maintenance and repair program, and signed a contract with the company.

These are the steel structure encased in glass curtain wall construction and processes.
