product description
It is made of high-quality carbon steel or stainless steel and is suitable for cracked concrete and non-cracked concrete. It can be customized according to customer needs.
Material
Galvanized carbon steel / stainless steel
Product advantages
1. Chemical tube composition: vinyl resin, quartz particles, curing agent
2. The glass tube is closed for packaging to facilitate visual inspection of the quality of the tube. After the glass is crushed, it acts as a fine aggregate.
3. Anti-acid and alkali, heat, fire, low temperature sensitivity
4. No expansion compressive stress on the substrate, suitable for heavy loads and various shock loads
5. Installation spacing and margin requirements are small
6. Quick installation, rapid curing, does not affect the construction progress
7. Wide range of construction temperatures
Applicable substrate
1. Planting of new concrete without pre-embedded steel
2. Applicable to the reinforcement and transformation project, the rooting of the screw and steel in the substrate
3. Various equipment, pipeline installation, curtain wall bracket fixing
4. Bonding and fixing of wooden members, plastic members and metal members
5. Applicable to the reinforcement of railways, highways, bridges, water conservancy renovation and expansion projects
6. Billboards, tunnel lines, elevated road baffles and guardrails
7. Suitable for all kinds of curtain wall stone hanging brackets fixed
Construction process
1, substrate drilling
Drill the substrate with professional drilling tools and impact hammers according to the dimensions required by the design drawings
2, cleaning the hole
Use the compressed gas to blow out the dust in the hole, and then use a special brush to clean the dust attached to the inner wall of the hole.
3, put the medicine tube
Check the fluidity of the resin by hand or visual inspection. After confirming, insert the drug into the bottom of the hole.
4, screw into the screw
Before the screw is buried, there is a 45° chamfer, the rear end is screwed in, the hex nut is driven by the power tool and screwed into the bottom of the hole.
5, curing curing
Allow the anchoring gel to solidify naturally, the curing time is based on the temperature reference curing schedule, and the screw should not be rotated or tapped during the curing period.
Storage
Storage period of 12 months, stored in a cool dry place
