Upsetting Thread 32mm Semi-grouting Coupler for Building
Introduction:
The grouting coupler is a combination of specially processed couplers, matched grouting materials and rebar. When connecting rebar, fast-hardening non-shrinking grouting materials are injected, the rebar and coupler are connected by the bonding and occlusal effect between the materials. The grouting coupler has the advantages of reliable performance, wide applicability and easy installation.
Grouting sleeve connection technology is suitable for reinforced concrete structure engineering, steel structure engineering, bridge engineering, offshore oil drilling platform engineering, offshore wind power tower and other fields. Grouting sleeve connection technology is a new type of steel structure connection method due to the needs of engineering practice and technological development. This connection method makes up for the shortcomings of traditional steel structure connection methods (welding and bolt connection), and has been rapidly developed and applied.

Advantage:
In practical engineering applications, the sleeve is pre-buried at the connecting end of the component when the prefabricated component is fabricated, and the exposed steel bar of another connecting component is inserted into the sleeve during on-site construction. After the component is installed and positioned, the steel bar is connected by grouting. Compared with welding, straight thread mechanical connection, the use of grouting coupler connection can reduce the workload of steel pre-processing, the steel bar will not produce secondary stress and deformation during on-site construction, and can accept relatively large T deviation
Application areas:
1) reinforced concrete structure engineering
2) steel structure engineering
3) bridge engineering
5) Highway constructure
6) offshore oil drilling platform
7) offshore wind power tower
