Anonymous users2024-02-061. Three tests need to be done: wind pressure deformation performance, air tightness performance and water tightness performance;
2. Some are also added: in-plane deformation performance and other performance testing, that is, the four properties that are often said; 3. Angle steel channel steel does not need to be retested; 4. The materials that need to be retested are:
1) Peel strength of aluminum-plastic composite panel;
2) the bending strength of stone, the freeze-thaw resistance of stone in cold areas, and the radioactivity of indoor granite; (3) The contamination of stone sealant.
4) Shore hardness of structural adhesive for curtain wall, tensile bond strength under standard conditions.
5) Compatibility and peel adhesion test of structural sealant and weather-resistant sealant for curtain wall and their contact materials (these two indicators cannot be provided in the factory inspection report of sealant, but must be re-inspected before sealing use);
5. The on-site experiments need to be done: (1) The on-site pulling test of the post-embedded parts, the number of extractions shall be carried out according to the proportion specified in the specification by random sampling;
2) Peel test of silicone structural sealant, the number of extractions is 1 piece for every 100 components;
3) If a two-component silicone structural sealant is used, a mixing (butterfly) test and a pull-off (glue cup) test should also be done. Just do a group of the same type;
4) The water test should be carried out in full;

Anonymous users2024-02-05Chemical anchors: pull-out test.
Steel: General physical properties (tensile and bending resistance).
Stone: flexural strength, water absorption, freeze-thaw test (done in cold areas and severe cold areas) Sealant: anti-pollution.
Curtain wall four sex test: water tightness, air tightness, wind pressure resistance, plane deformation (required).

Anonymous users2024-02-03Stone curtain wall is unfamiliar to many people, so let's take a look at the stone curtain wall and what are the items that need to be tested for stone curtain wall!
What is a stone curtain wall.
The stone curtain wall is composed of steel structure, glass ribs, etc., and the way of installation is dry hanging, but the dry hanging is higher for the wet paste, but there are certain benefits, because the dry hanging method is safer, more reliable, and not easy to fall, so the generally higher wall is used dry hanging; The wet paste on the exterior wall is prone to alkali phenomenon, which affects the appearance of the curtain wall; And the freeze-thaw resistance of the wet paste is also relatively disassembled, and it is easy to have problems if it is in a frozen area.
Stone curtain wall needs to be inspected what must be done.
1. The stone curtain wall needs to be tested for three properties, namely: wind pressure deformation performance, watertightness and airtightness.
2. Some are also added: in-plane deformation performance or other performance testing, which is often referred to as the four natures.
3. Angle steel channel steel does not need to be retested;
4. The materials that need to be retested are:
Glass strength of aluminum-plastic composite panels.
The bending of the stone is mild, the freeze-thaw resistance of the stone in cold regions and the radioactivity of granite for indoor use.
Contamination of stone sealants.
The curtain wall needs the Shaw hardness of structural adhesive and the tensile bond strength under standard conditions.
Curtain walls need to be tested for compatibility and peel adhesion of structural sealants, weather-resistant sealants and their contact materials.
5. There are those who need to do field tests.
The pull-out test of embedded parts can be carried out according to the requirements of relevant regulations, from which the corresponding number of embedded parts can be extracted, and then the test will be carried out by random sampling in proportion.
The silicone structure of 100 components was extracted to make silver sealant, and then the peel test was carried out, and one piece of each component was extracted for testing.
If the stone curtain wall is made of two-component silicone structural sealant, then the mixing and tensile test should be done, but only one set of the same type needs to be done.
The water test was carried out in full.
Summary: The above is about the stone curtain pure smile banquet wall needs to do what must be done to do the relevant content, through the above content we also have a certain understanding of the stone curtain wall, I hope to help you, want to know more about the relevant content, you can pay attention to Qijia.com.

Anonymous users2024-02-01Hello, I am happy to serve you and give you the following answers: stone curtain wall inspection is generally divided into three groups: 1
Size inspection: check whether the size of the stone meets the requirements, and whether the gap between the stones is consistent. 2.
Quality inspection: check the quality of the stone, including the surface quality of the stone, the texture of the stone, the structure of the stone, etc. 3.
Installation inspection: check whether the installation of the stone conforms to the rules and regulations, and whether the installation of the stone is firm. Workaround and Procedure Steps:
1.First of all, the size of the stone should be tested to check whether the size of the stone meets the requirements and whether the gap between the stones is consistent. 2.
Secondly, the quality of the stone should be inspected to check the quality of the stone, including the surface quality of the stone, the texture of the stone, the structure of the stone, etc. 3.Finally, the stone should be inspected for installation to check whether the installation of the stone meets the specifications and whether the installation of the stone is firm.
Personal tip: When conducting a stone curtain wall inspection, you should carefully check the size, quality and installation of the stone to ensure the quality of the stone and the quality of the installation. In addition, the stone should be inspected regularly to ensure the quality of the stone and the quality of installation.
