Do you know concrete anchor epoxy?

In recent years, epoxy reinforced rubber has been applied to a variety of construction projects. Small buildings, large buildings and highway extension reinforcement all need to use epoxy reinforced rubber. In tunnel, railway, highway, water conservancy and other fields, epoxy reinforced rubber is needed to strengthen the building structure. For example, the structural column in the new concrete structure, to ensure the close reinforcement of the concrete and the column, it is necessary to use the planting reinforcement anchorage technology, with epoxy planting reinforcement glue will be closely combined with the reinforcement and concrete, and then play the role of vertical connection reinforcement; Epoxy planting reinforcement anchoring technology can also be used in the repair of large building structures such as bridge retaining walls to reduce the amount of damage caused by engineering demolition, ensure the integrity of the building structure and extend the service life.

1.What is concrete anchor epoxy sealant?

Anchoring epoxy sealant is A and B two-component epoxy adhesive,which has thixotropy,high tensile and shear strength and shear strength,good aging resistance and fatigue resistance,and excellent load-displacement characteristics.Trough bonding and locking,it achieves the effect as embedded.The glue needs a small hole,vertical hole,horizontal hole,inverted the hole can easily planting reinforcement.Usually drilling diameterd+4-8mm,anchoring length 15d,the anchorage force value of the planted steel bar is generally greater than the yield value, meet the requirements of 'concrete structure reinforcement design Code GB50367-2006' grade A glue.

2.The main characteristics of epoxy reinforced rubber

1) Fast bearing capacity, large anchoring force and good durability.

2) Small slip, can timely control substrate separation and deformation.

3) Excellent aging resistance, chemical corrosion resistance and water resistance.

4) The rubber does not contain volatile solvent, low shrinkage rate after curing, shrinkage rate can be reduced to less than 1%.

3.The specific application range of epoxy planting reinforcement adhesive

1) Planting of unembedded steel bars in new concrete.

2) It is suitable for planting roots of screw and reinforcement in the substrate in reinforcement and renovation projects.

3) All kinds of equipment, pipeline installation, curtain wall bracket fixation.

4) Bonding and fixing of wood components, plastic components and metal components.

4.Construction process of epoxy planting reinforcement glue

Drilling → cleaning → gluing → gluing → planting reinforcement → curing → quality inspection

Epoxy anchor adhesive has good corrosion resistance and aging resistance, low curing shrinkage rate, can be cured at room temperature, excellent bonding performance and a wide range of bonding, can be bonded to concrete, metal and cement and other substrates. Epoxy anchoring adhesive can be used in a variety of building structures in the reinforcement, screw embedding, building structure reinforcement and reinforcement; Industrial plant, railway, road, bridge, water conservancy and hydropower and other infrastructure renovation and expansion engineering reinforcement; Billboard, tunnel pipeline, overhead road sound insulation board and guardrail fixed.
