High rise building glass design aluminum frame waterproof structures glass curtain walls

Product introduction

The glass curtain wall is the product of the development of modern science and technology, and it is also a significant feature of the modern high-rise building era. The energy-saving way of glass curtain wall is usually to reduce the heat transfer coefficient of the structure by using coated glass, LOW-E glass, heat reflective glass, insulating glass and thermal bridge aluminum profiles, eliminate the "thermal bridge" of the structural system, and reduce the heat loss of air infiltration, It is achieved by improving the sealing performance, etc.

Specification

Construction Technology:

1. Preparations for steel structure installation and welding

The test steels include Q345GJC-Z15 (70mm wall thickness), Q345GJC-Z15 (40mm wall thickness), Q345C (28mm flange thickness), and the welding positions are column-column horizontal welding and column-beam flat welding (including the upper and lower flanges of truss beams). welding), T-shaped corner vertical welding. Groove form and size according to design requirements. After welding, the appearance and ultrasonic inspection were qualified and samples were taken for mechanical and physical tests.

The test results showed that the tensile strength of the joint reached the standard value of the tensile strength of the base metal, and the joint was bent 180° without cracks. The welding materials and welding equipment used shall meet the national standards and have excellent performance. The devices for cleaning slag, air gouging, electrode drying and heat preservation should be complete and effective.

2. Welding materials and equipment for manual arc welding and CO2 gas shielded welding

(1) The electrode should be dried in a high-temperature drying oven, and the number of times the electrode should be dried should not exceed two times.

(2) The packaging of the welding wire should be in good condition. If it is damaged, the welding wire should be partially discarded if it is contaminated, bent or disordered.

(3) The purity of CO2 gas should not be less than 99.9% (volume ratio), the water content should be less than 0.05% (weight ratio), and the use of the bottle should be stopped when the high pressure in the bottle is lower than 1MPa.

(4) The voltage of the welding machine should be normal, the ground wire should be firmly pressed, and the contact should be reliable.

3. Installation and welding procedures and general regulations

The general sequence of welding is: pre-welding inspection → preheating and rust removal → installation of welding pad and arc strike plate → welding → inspection

1. Before welding, check the groove angle, blunt edge, gap and offset amount, and the rust spots, oil stains, iron oxide scale, etc. in the groove and on both sides should be clean.

2. Preheat. Before welding, use gas welding or a special baking gun to uniformly heat the groove and the base metal within 100mm on both sides, and measure the temperature with a surface thermometer to prevent the temperature from not meeting the requirements or local oxidation of the surface, and preheat the temperature.

3. Re-check the preheating temperature, if the temperature is not enough, it should be reheated to make it meet the requirements.

4. When installing the welding backing plate and the arc striking plate, the surface cleanliness requirements are the same as the groove surface. The backing plate and the base metal should be closely attached, and the arc striking plate and the base metal should be welded firmly.

5. Welding: The weld bead of the first layer should seal the connection between the base metal and the backing plate in the groove, and then weld layer by layer until the groove is filled. Welding defects should be removed and repaired in time.

6. A joint must be welded continuously. If the welding is stopped halfway as a last resort, it should be treated with heat preservation and slow cooling. Before re-welding, it should be reheated according to the regulations.

7. Welding should be stopped in case of rain or snow, and there should be wind shields and canopies around and above the welding joints of components. Welding should be stopped when the wind speed is greater than 5m/s. When the ambient temperature is lower than zero, preheating and post-heating measures should be taken according to regulations.

8. The carbon structural steel should be cooled to the ambient temperature in the weld, and the low-alloy structural steel should be tested for weld flaw detection 24 hours after completion.

9. Welders and inspectors should fill in the work record form carefully.
