External wall insulation board pull-out test method does anyone know?

The test method and result determination of the pull-out test of the external wall insulation board shall be in accordance with the provisions of the "Standard for Inspection of Bonding Strength of Decorative Bricks in Construction Engineering" (JGJ110).

EPS board cast-in-place concrete exterior wall insulation system strength shall not be less than 0.1MPA, and the damage part shall be located in the EPS board. The requirements of the field test method is that the concrete should be cured 28D after casting, the measurement point selection, **** measurement of 9 points.

The specimen specification should be 95mm x 45mm or 40mm x 40mm, similar walls, each group of 3 tests.

Testing method:

Breakage should be cut 2d to 3d before the bond strength test, breakage should be cut from the surface of the finish brick to the surface of the substrate, the depth should be consistent.

External wall insulation test content:

1, the entire external thermal insulation system materials retest test, including insulation board retest test, mesh cloth test, insulation nail test, adhesive test, plastering mortar test, as well as powdered particles of the test; test batch is based on the height of the project building decision, the building in the 20-story or less, each building to do the above materials three batches of testing, 20-story or less, each building to do the above materials. The test batch is decided according to the height of the project building, the building in 20 floors below, each building to do the above material 3 batches of testing, 20 floors above each building to do 6 batches of testing.

2, in the construction site of each building to do 2 batches of benzene board and anchor bolt pull-out test test in the construction process.

3, after the completion of construction, each building's exterior wall to do a batch of surface impact resistance test, select 2 points.
