When the building beam and the wall are connected, there will always be some problems. In the past, the method of using pre-embedded steel bars was used. When welding embedded parts and steel bars, the quality was difficult to be ensured due to the small operating conditions and welding area. The welding was often weak, and it was easy to break after repeated external force. This construction is both cumbersome and laborious, reducing labor efficiency. These problems were solved until the appearance of structural planting bar adhesive.
However, if you don't pay attention to the following five points during construction, it may be that your structural planting bar adhesive is not able to achieve the effect you want.
1 The key to anchoring and planting bar is to clear the hole, to ensure that the inner wall of the hole is clean and dry, to ensure that the bond strength between the structural adhesive and concrete can meet the design requirements.
2 The depth of anchoring and planting bar should be determined according to the concrete strength grade and the specification of the steel bar and the technical parameters required by the drawing design, and the effective implantation test should be carried out to determine the appropriate implant depth. Otherwise, it is difficult to fully exert the strength of the steel bar.
3 The ratio, metering and the dosage of the planting bar adhesive must be accurately mastered, otherwise the colloidal setting time is not well controlled, and the colloidal condensation and curing shrinkage affect the bonding strength.
4 Use a rust-free steel bar to implant the hole and pay attention to rotating the bar in one direction.
5 Use high-quality structural adhesives. For example, Mankate Technology's products are mainly composed of epoxy resin and curing agent. They are A and B two-component epoxy adhesive with thixotropic properties, high tensile and shear strength, excellent resistance to aging and fatigue. The load-displacement performance is better, and the effect of embedding is achieved by bonding and locking.
Generally speaking, by doing the above five points, it is possible to shorten the construction period and improve the effect of work efficiency. The structural adhesive can also play its role. If you are interested in this product, please call our one-stop service hotline: 400-894-5118.
