There are more details that need to pay attention to the construction of the curtain wall keel construction, and it will be dealt with as well as possible, otherwise it is likely to bring hidden dangers, which will affect the later use. So what are the requirements and quality problems of the curtain wall keel welding.
What are the requirements and quality issues of curtain wall keel welding.
Welding requirements.
1. Clean up dirt.
The foundation surface should be cleaned up, and the prominent area that affects the installation of the skeleton needs to be cleaned, and the strength of the wall meets the design specifications.
2. Determine the installation position of the keel.
Determine the installation area of the keel and the building curtain wall according to the panel grid bounced from the wall.
3. Put the control line.
According to the design elevation requirements, the horizontal control line and vertical keel division of the foot bolts and expansion bolt holes in the wall are arranged in the wall. Founder.
4. Structure and embedded parts.
According to measurement, the layout results to see if the accuracy of the curtain wall installation accuracy is reached, check whether the pre -buried parts can reach the installation of the adapter.
The advantages and disadvantages of stone curtain walls.
advantage:.
Natural material, light and crystal, hard and forever, noble and elegant.
Frozen resistance: Stone building curtain walls can resist freezing without significant destruction in a humid state. This performance is called freezing resistance. When the water in the rock pores is low to minus 20 Celsius, freezing occurs. The freezing occurs. The expansion of water in the pores is 1/10 larger than the original volume. If the rock cannot resist the force of such expansion, the destruction will occur. Generally, if the water absorption rate is less than 0 or 5%, it will not consider its freezing resistance.
Compressor strength: The pressure resistance of stone will be different due to the composition of minerals, crystallization thickness, the uniformity of the tunnel, the weight of the load, the weight of the load, and the angle of the lotus. The tight materials that are small and bonded with each other have a high strength. After drying and saturated water, the dense volcanic rock has no difference in pressure resistance (very low water absorption rate). The strength of dryness and humidity is significantly different.
shortcoming:.
The bulky stone is not fully standardized for the bidding bidding in the construction industry in the construction industry. In order not to lose money, we must cut corners, and the building curtain wall.
