What Are the Characteristics of the Unit Curtain Wall? -WJW Aluminum Supplier Aluminum

Unit curtain wall "can be divided into:" unit curtain wall "and" semi -unit curtain wall ", also known as" strong unit curtain wall ", semi -unit curtain wall can be divided into: vertical support unit combination curtain wall, curtain wall unit curtain wall. The classification of the unit curtain wall is different. However, its basic principles are exactly the same. It is essentially different from the production principles of frame curtain walls in design and construction. It introduces the characteristics of the unit curtain wall: "".

1. Unit type solving the problem of curtain wall leakage, adopt the principle of "voltage". There must be three conditions for leakage on the curtain wall.

The first is the existence of water, such as the rainwater curtain wall water.

Second, the way of water flow;

Third, the movement of water has six forces, such as gravity, momentum, surface expansion, capillary, airflow and pressure difference. "The pressure difference is the main reason for the leakage of most curtain wall joints. The water content outside the curtain wall, whether it is rain or laundering to enter the room, must not only have rupture or cracks, but also requires that the outdoor pressure is higher than the indoor pressure. If the pressure indoor pressure is equal to outdoor pressure, even more than the outdoor pressure, even if there is rupture or crack, the moisture will not enter the wall. "Generally, the traditional waterproof method is to minimize the opening that may appear at the long joint, such as using various sealing agents, tape tape -connecting seams, etc. "The new method of entering the indoor waterproof is to adjust the water into the cavity, and then drain the water from the wall by dredging rainwater. In order to achieve waiting for pressure, we maintain part or all seams to open, but when the pressure cavity is not a ventilation space, we must limit the ventilation space within a certain range in order to effectively produce the pressure effects of the real estate. "In order to achieve a complete pressure effect, the pressure in the" cavity "must be maintained at any time than or equal to outdoor pressure. However, we know that due to changes in wind speed, the surface pressure of the building will not remain unchanged forever. "The higher the building, the more obvious the pressure difference is. The positive wind pressure near the ground is small, and the positive wind pressure at the center of the facade is greater than the positive wind pressure at the corner. The same horizontal material may be positive pressure on one end, and the other end may be negative. Difficulty. Therefore, a high -tech solution is needed. The principle of the pressure is the unique core of the unit curtain wall.

2. The unit height of the unit curtain wall is the height of the floor, and the width is generally 1.2 meters to 1.5 meters. Therefore, the transmission is simple and can be directly hung on the floor burial parts for easy installation.

3. Single pieces can be processed and manufactured in the factory. Glass, aluminum plates or other materials can be assembled on the single component of the processing plant, which promotes the industrialization of the building.

4. Because the entire part of the single -piece assembly in the processing plant is convenient for factories, it is conducive to ensuring the diversification of the overall quality of the curtain wall, and the engineering quality of the curtain wall.

5. The unit curtain wall that can be installed in the lower direction of the ground with civil engineering projects has greatly shortened the engineering cycle.

6. All projects of the unit curtain wall can be completed on the ground, and high -rise scaffolding and cranes can be saved during the installation process.

7. The structural design of the curtain wall unit installation of the connection interface can absorb layers of displacement and unit deformation. Generally, it can withstand large -scale buildings to move, which is particularly beneficial to high -rise buildings and steel structure buildings.

8. The unit curtain wall can be realized and maintains a double -layer sealing system.

9. After the unit curtain wall is installed, the silicone sealant cannot be injected into the cells between the unit and the unit (some can also be injected (some can also be injected, depending on the different installation method).

10. The seams of the unit curtain wall framework are tightly arranged into a straight line, which facilitates the formation of a good external wall image.

11. The positioning and installation accuracy of unit curtain wall burials is high.

12. The unit curtain wall needs to adopt high -tech design principles. The contractor needs some advanced design talents and equipment. Only the powerful curtain wall company can build a unit curtain wall.

13. The unit curtain wall requires a large number of high -tech components. The shape of aluminum profiles is relatively complicated, and the number of aluminum profiles is also large. Its shape is slightly higher than the frame curtain wall. (Never be several times higher than the frame curtain wall).

14. Compare the advantages and disadvantages of the unit curtain wall and frame curtain wall. This is not absolute. The comparison of various curtain walls should be based on specific actual situation.
