chemical anchor bolt Material Quality Inspection
The screw and anchoring glue of chemical anchor bolts must meet the design requirements and should have a factory certificate and test report. The material, specification and performance of the screw and anchoring glue should comply with relevant standards, and their components should not be replaced at will.
FIXDEX chemical anchor Construction process inspection
Drilling should be done before construction. The hole diameter, hole depth and bolt diameter should be determined by professional technicians or on-site tests.
After drilling, the dust and water in the hole should be cleaned up to ensure that the hole is dry and free of impurities.
During installation, the screw should be rotated and inserted forcefully until the bottom of the hole, and impact should be avoided.
best chemical anchor Pull-off test:
Chemical anchors should be subjected to pull-out tests to verify their anchoring force. The pull-out test should be carried out in accordance with the standard, and the pull-out force and pull-out depth should be recorded.
The pull-out test should be carried out at room temperature, and the humidity should be controlled within 60% to ensure the stability of the test environment.
Environmental adaptability:
The use environment of chemical anchors should consider whether the base material is cracked, the stress properties of the anchor connection, the type of connected structure, and the seismic fortification requirements.
In special environments, such as chloride ion environments or high humidity environments, anchors made of special materials should be used, such as stainless steel or highly corrosion-resistant stainless steel.
bolt chemical anchor Anti-corrosion treatment
Metal anchor bolts should take appropriate anti-corrosion measures according to the use environment, such as galvanizing or using stainless steel.
In outdoor environments, high humidity environments or chemically corrosive environments, special attention should be paid to the effectiveness of anti-corrosion treatment.
