Hone / Product / Curtain wall anchoring / High-strength chemical anchor

HILTI HVAHigh-strength chemical anchor

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

1. The table installation data unit is mm, technical parameter unit kN

2. The table data is based on C20/C25 substrate concrete. If the grade of the substrate changes, the requirements of the technical department and the design drawings should be followed.

3. Form stainless steel 316 is A4-70 stainless steel

4. The table design load contains the material safety factor.

5. Form data is suitable for: correct installation, no margin, no spacing effect, minimum substrate thickness

6. For products not listed in the table, please refer to JGJ145-2013 Technical Specification for Post-Anchage of Concrete Structures. According to the calculation method of the ultimate state of bearing capacity, the corresponding data is obtained. For details, please consult the technical department of Shibang (Shanghai) Industrial Co., Ltd.
