Article 6: Prestressing Equipment and Stressing Work for Civil Bridge and Buildings Construction

Following my last article 5, this article is mainly introduction the stressing equipment and work in bridge and building construction. We use Post-Tension method and Pre-stressing Method and technology for bridge or building construction.

Post-Tension work for bridge in China is applied tensioning from two side of bridge girders, use two jack installed both two sides to tension simultaneously. We supply post-tension jack and pump from 24 tons to 1200 tons.

Pre-tension method is usually used in prestressed concrete work,such as precast factory, precast bed slab, bridges hogging moment, etc. We supply 24 tons and 27 tons monostrand jack, 65 tons to 1000 tons lifting jack for pre-tension work.

Post tension ducts, reinforcing bar and vent pipes installation and fixing for bridge girder

1. Galvanized metal duct for post tension

2. HDPE plastic duct with black color for post-tensioning

3. HDPE plastic duct with yellow color for post-tensioning , amazing project.

4. Vent pipes installation and fixing

5. Reinforcing bar installation and fixing for post-tensioning

6. Round anchor block, wedges,anchor bearing plate and reinforcing bar installation

7. Flat anchor block, wedges,anchor bearing plate and reinforcing bar installation

Continuous Bridge Girders

In bridges girders, especially for railway, high-speed railway, highway projects, the continuous bridge girder is for purpose of linking beams and girders, it is very important part in bridge construction. We often use multistrands anchor coupler for continuous bridge girder. Our multistrands anchor coupler ranges have single anchor coupler, multistrands anchor coupler from 2 holes to 55 holes.

The multistrands anchor coupler include: anchor coupler body, dead end anchor(swages anchor), anchor coupler bearing plate, spiral spring rings, wedges, constrain rings, pocket former( we usually use metal materials pocket former).

Dead end anchor(swage anchor) for post-tensioning

Sometime we use H type bulbing dead end anchor

H type bulbing dead end anchor is used in bridge surface construction
