Requirement and Construction Technology of Curtain Wall Engineering Construction Technology! -Ruminum Profiles Supplier

The board supports the curtain wall, and the surroundings of the glass embedded board are supported by the metal frame. The main content of the curtain wall is now:

(1) Bright frame glass curtain wall: The components of the metal frame are exposed to the glass curtain wall of the micro -frame on the outside of the panel;

(2) Hidden frame glass curtain wall: The metal framework is not almost revealed to support the glass curtain wall of the micro -frame on the outside of the panel;

(3) Semi -hidden frame glass curtain wall: The horizontal or vertical components of the metal frame are exposed to the glass curtain wall slightly frame on the outside of the panel.

1. Category according to the panel material of the building curtain wall

(1) Full glass curtain wall: It is composed of glass and glass embedded plates for glass curtain walls; dotted glass curtain walls: from glass embedded boards, support installation construction and supporting construction composition for glass-curtain wall;

(2) Metal curtain wall: The panel is a building curtain wall with metal slices, which mainly includes, single -sided aluminum board curtain wall, aluminum -plastic composite board curtain wall, honeycomb aluminum board curtain wall, stainless steel (stainless steel) curtain wall, enamel board curtain wall, etc.;

(3) Stone curtain wall: The panel is the architectural curtain wall of the building stone (Granite);

(4) Artificial metal board curtain wall: panel, pottery plate, microcrystalline board, glass plate U -shaped board and other special materials for curtain walls;

(5) Combination curtain wall: The panel consisting of glass, metal, stone, and artificial plates such as different surface sectors.

2. Classification of the construction method of the curtain wall

(1) Unit curtain wall: assemble panels with beams and columns as the curtain wall unit in the factory. The completion of the device framework from the form of the curtain wall unit is to support the construction curtain wall (the height of the unit plate of the generic drug is due to the height of a floor.)

(2) Component curtain wall: Install the frame of the building in order to install the columns, beams and panels in order to support the building curtain wall.

3. The new curtain walls include double -layer curtain walls, photoelectric curtain walls, etc. The main part of the optoelectronic curtain wall is specially material. It can produce optoelectronics and use it to use it through contact with the sun.

4. The construction order and construction technology of the curtain wall project

(1) Construction sequence: Founding the line and checking whether the building drawing matches the building at the scene.

If there is an error, the error can be adjusted on the spot. In the biggest mistakes, inform the design unit and the building unit, and make adjustments and design modifications after the actual situation of the construction site.

(2) The construction order of the curtain wall: Founding -rear buried plate installation -framework installation fire prevention lightning protection baffle cleaning glue self -examination -acceptance -transfer. The rear panel often uses the construction method to install the correct position, horizontal and vertical, and the correct position of chemical bolts. Drilling, pore diameter according to the diameter of the bolt, the average pore diameter is greater than the bolt diameter of 2mm, and the pore depth is determined by the length of the bolt. The dust in the hole should be cleaned out. After the tube is put, the bolt should be turned into at a low speed of the mechanical. It is not allowed to hit it directly with a hammer.

(3) Before the installation of the frame, you must first affirm whether the position of the pillar is affirmed. After the column is completed, the self -check is determined. The main incentives, the steel corner code welding must meet the requirements of the specifications, the length of the weld must meet the design needs. Generally, it must not be less than 60mm. The weld cannot be allowed to leak welding, and there must be no bubbles and empty drums. Clean the welding residue in time, and make continuous anti -corrosion, anti -rust paint twice, silver powder twice. The aluminum angle code connected to the column to ensure that each contact surface of each contact surface is three self -attack screws, prevent twisting, deformation, drooping, fireproof lightning protection according to specifications and construction drawing structures.

Generally, the position of the firefighting layer is installed at the outer edge of the floor floor and the curtain wall. Each piece is connected, bolt, and pads should be tight, and it cannot be allowed to be loose. The column joint is connected with a 250mm sleeve, and the gap between 15mm between the upper and lower columns is not less than 15mm. Anti -anticorrosive flexible isolation isolates between them to prevent it from corrosion of dual metals.

(4) Installation of glass embedded plates, hidden frame glass curtain wall installation: glass and auxiliary board injection layer in the indoor glue of cleaning and ventilation. The temperature and humidity conditions in the city should comply with the requirements of structural products. The temperature is between 15-30 degrees and the relative humidity is more than 50%. Before the silicone gum sealing glue, it must be obtained by a qualified compatibility report. Before the glue, Gradebel Pstraer should be rubbed and cleaned.

Generally, acetone is washed and washed. After scrubbing, the acetone was dried through the drying glue, but the time of injection should be within one hour. In the body layer, the glue must be dense, uniform, non -bubble, smooth and smooth surface. Do a good job of injection pumps and various experimental records.

The era of glue solidification in a component structure requires 7-10 days. The peeling test should be performed before installing the glass. Boxing frame curtain wall: The installation of the glass embedded plate of the bright frame curtain wall may not be directly linked to the frame component. The glass around the glass and the bottom of the component groove must be empty gap, and each glass is under each glass.
