How to install the glass curtain wall? Introduction of construction technology

Outside some office buildings or high-end institutions, we will find a lot of bright glass installed on the periphery, which is generally similar to the glass curtain wall mentioned below. Different from ordinary transparent glass, this kind of glass curtain wall can not only ensure the overall beauty, but also have good lighting and strong performance. So today's example is about the scheme and technology of glass curtain wall construction and installation. Interested friends may wish to draw up a satisfactory plan with reference to the actual situation.

A, glass curtain wall installation construction scheme

1.？ Collect and prepare relevant information and tools.

Before construction, it is necessary to collect relevant information at the construction site. Due to some changes in civil construction, the actual dimensions may not all meet the design drawings. All-glass curtain wall requires higher dimensions than civil structures. Therefore, before the design, we must go to the site to measure and obtain first-hand information, and then we can draw a feasible curtain wall separation diagram according to the requirements of the owner. For the part with the entrance and exit of the gate, it must also cooperate with the unit that makes the automatic revolving door and all-glass door, so that the glass curtain wall can be reliably closed on the door and the door, and at the same time, it must meet the installation and maintenance requirements of the automatic revolving door. The tools to be used should also be prepared in advance.

2? Determination of design and construction scheme

When designing the partition of glass curtain wall, we should not only consider the uniform and beautiful appearance, but also pay attention to reducing the specifications and models of glass as much as possible. Due to the different outdoor designs of various buildings, more attention should be paid to coordinating the overall construction sequence and progress for outdoor awnings, driving ramps and other projects to prevent crane walking and glass curtain wall installation from being affected by the construction of other outdoor facilities. Before the formal construction, the site within the construction scope should be leveled and filled, and the site should be cleaned to ensure the smooth operation of the crane.

Second, the glass curtain wall construction practices and construction technology

1, curtain wall installation

1) Use (laser) theodolite, level meter, line hammer and other instruments and tools to measure the center position of the connection point between the frame material and the main structure layer by layer, and the allowable deviation in the three directions of X, Y and Z axes is1.0 mm.

2) For the component curtain wall, if the glass is tempered glass, insulating glass and other glass that cannot be cut on site, the actual size of the glass should be checked in advance. If it does not meet the design size, the center position of the connection point between the frame material and the main structure should be adjusted. Or the glass can be customized according to the actual installation position (size) of the frame material.

3) according to the determination of the center position of the connection point to fix the connector, to ensure firm.

4) The installation of unit curtain wall should be carried out from bottom to top. Element curtain wall frame material should be installed from top to bottom.

5) When the frame material of the unit curtain wall or each unit of the unit curtain wall is connected with the connector, the whole curtain wall should be inspected and corrected, and then the connector should be welded firmly with the embedded parts of the main structure (including anchoring with expansion bolts).

6) The clearance of the unitized curtain wall shall be sealed with V-shape, W-shape or other rubber strip, and the sealing shall be tight, without omission.

7) The component curtain wall shall be installed with glass according to the requirements of design drawings. After the glass is installed in place, it should be fixed on the frame with embedded materials such as rubber strip in time, and temporary fixing or shelving is not allowed.

2. Installation technology of unit curtain wall

On-site installation process of unit curtain wall is as follows:

Measuring and setting out → checking the position of embedded T-shaped groove → threading screws → fixing brackets → accurately locating brackets → welding brackets → roughly hanging V-shaped and W-shaped tapes → hoisting curtain wall with damping rubber pads → fastening screws → adjusting the straightness of curtain wall → filling hot-pressing windbreak belts → installing indoor window sill plates and inner corner braces → filling fire-proof and heat-insulating materials between beams and columns.

3. Installation technology of modular curtain wall

1) installation technology of open frame glass curtain wall

Inspection, classification and stacking of curtain wall components → measurement and setting out → assembly of primary and secondary keels → installation of floor fasteners → installation of main keels (rigid rods) and leveling and adjustment → installation of secondary keels (crossbars) → installation of thermal insulation galvanized steel plates → welding riveting screws on galvanized steel plates → installation of interlayer protective mineral wool → installation of floor closed galvanized plates → installation of single-layer glass window sealing strips and clips → installation.

2) Installation technology of hidden frame glass curtain wall

Measuring and setting out → installing fixed supports → installing columns and cross bars → installing external protective structural members → sealing and sealing treatment of external protective structural members → fire barrier treatment → cleaning, etc.

4, frameless glass installation process

Because the glass is long, large and heavy, the mechanized construction method is generally adopted in the construction, that is, the electric vacuum sucker is installed on the forklift to suck the glass in place, the operator stands on the scaffolding set up on both sides of the upper end of the glass, and the upper end of the glass is fixed with the clamping device, and each glass is caulked with silica gel.

The above example is about the installation scheme, construction practice and construction technology of glass curtain wall. Therefore, the suitable glass curtain wall is generally used in the periphery of high-grade office buildings or some hotels. They are designed with some metal supporting materials, so they not only have good lighting ability, but also can resist wind pressure, moisture and frost, sound insulation and heat insulation. It is a new building material product, but the use effect of this part should be guaranteed from the previous installation technology and construction scheme. For example, Bian Xiao today is specific to everyone.
