Why should the curtain wall do the six sex test? What is the six sex test?

The six-sex test is mainly done for building curtain walls.

security, practicality! The main ways to prevent rainwater leakage and their countermeasures: Gravity: In the process of rainwater falling, it encounters a sloping gap and flows directly into the room Tension: The tension capillary phenomenon along the surface of the material along the process of rainwater falling.

Capillary phenomenon occurs when the gap is small Movement: During the rainwater falling process, the wind speed drives the rainwater into the gap Pressure difference: The indoor and outdoor pressure difference caused by the wind during the rainwater falling.

The six tests refer to: wind pressure resistance, air tightness, water tightness, in-plane deformation performance, heat preservation, and sound insulation.

You are talking about the technical specification of glass curtain wall engineering JGJ102-2003

Wind pressure resistance, air tightness, and water tightness are the basics, and then adding an in-plane deformation performance is the four properties, and then adding thermal insulation and sound insulation is the six properties. Which uncle does so much for them? According to national norms, no matter how many squares you have to do.

If it is private, basically do not do it, public work, the first three than do, the latter depends on whether the design has thermal insulation, heat insulation, etc., if there are requirements, you have to do it.

The height of the building curtain wall 2007 is less than 24 meters, and the area is not more than 300 square meters, the curtain wall products can not be tested for the mandatory inspection of the curtain wall. The results can be tested in the form of similar products.

1) Test content: building curtain wall airtight, watertight, wind pressure resistance, in-plane deformation performance.

2) Detection nature: In order to determine whether the curtain wall in the project meets the design requirements, the curtain wall performance test should be carried out for each curtain wall project.

3) Other matters: At present, the four properties of the curtain wall of the project in China are only tested on the curtain wall specimens, and the test results are responsible for the specimens.

Specification basis 1: "Technical Code for Glass Curtain Wall Engineering" (JGJ102-2003), P15: glass curtain wall performance testing items, should include wind pressure resistance, air tightness and water tightness, if necessary, increase in-plane deformation performance and other performance testing.

In the explanation of the provisions, it is explained that when there are seismic requirements, the in-plane deformation performance detection can be added.

Specification basis 2: "Glass Curtain Wall Engineering Quality Inspection Standards" (JGJ T139-2001), P20: glass curtain wall installation, must submit the inspection report of the air permeability performance, rainwater leakage performance and wind pressure deformation performance of the glass curtain wall products used in the project, and should also submit the inspection report including in-plane deformation performance, thermal insulation performance, etc. according to the requirements of the design.
