Chemical Anchor Flat Head made by carbon steel,assembled with hex nut and washer and to hit the head by hammer and to use chemical adhesive capsule during installation.
Chemical anchor threaded stud with flat head is one kind of chemical anchor stud system and fixed in the drill hole of the concrete substrate by the chemical adhesive capsule or injection resin and to hit the head by the hammer directly to adjust the depth and to realize the anchoring of the fixed parts of the composite parts.
The concrete stud anchors are available with the carbon steel from 4.8 grade to 8.8 grade with heat treatment and the stainless steel 304 or 316 materials. The are able to be fixed in the underwater. They are non-expansion featrues type fasteners when installation in pre-drilled holes. They comprise of a steel stud available in flat head, external hex head and internal head assembled a nut and washer. Fixing of the stud is achieved by inserting a suitable curing resin into the hole using a glass chemical capsule or injection type adhesive system.
Concrete stud anchor is mainly designed for the connection and fixation of post installed rebar and thrreaded stud or rod in concrete substrate, without expansion performance. It is pre installed with a nut and falt washer for fastening. The tail is cut into 45 degree angle or flat shape. The head has inner hex head, outer hex head and flat head. The whole stud body is full of external threads. It is mainly made of carbon steel and stainless steel with the same shape and size.
When used and installed with chemical glass tube capsule and injection resin adhesive, it makes the chemical bond more firm and more durable under high load, and can extend the application from small fastening to structural reinforcement. Chemical anchors can be used to make the new buildings and old houses more durable. When the reinforced frame is inserted into the foundation building, it is required that both of them have good cohesiveness and bearing capacity. Chemical anchor studs are used to bond reinforcing bars to threaded rods or studs and have good strength to hold the connections in place and are strong enough to withstand loads. Especially in the reconstruction of old buildings, the use of embedded reinforcement can improve the structural strength.
Brief introduction of chemical anchor:
Chemical anchor is a kind of installation fixings used to fix anchor bolt on base material such as bedrock or concrete. The chemical glass capsule for chemical bonding consists of an outer glass container containing the main material composed of liquid unsaturated resin and granular aggregate, and an inner container containing curing agent embedded in the main material. It is a high load adhesive system, which is used to attach the substrate to the substrate to be attached. It is also suitable for aseismic and aseismic buildings and underwater installation. It must comply with the corresponding curing time.
Application of construction and installation:
A). Building, concrete foundation and roof, emergency staircase, concrete column reinforcement, external wall and enclosure angle, balcony reinforcement, steel foundation, etc.
B). Road foundation, guardrail, road sign, guardrail, viaduct, etc.
C). Subway tunnel, bridge engineering, wharf construction.
1. Drill a hole in the base material to suit the diameter and embedment depth of the chemical stud anchor used.
2. Clean the dust and debris from the hole,
3. Inject (mix) adhesive into about half of the hole, starting at the bottom, first into the hole to suit the type of stud anchor used.
4. Insert concrete stud anchor into the hole and rotate the hexagonal drive type by hand or by using a hammer drill and drive drill.
5. Allow the recommended time to cure the adhesive and then apply the load. Do not interfere with the stud anchors during curing.
