The following is pictures of our prestressing and post-tensioning equipment.

Prestressing and post-tensioning equipment.

There following my last article 6, this article mainly introduce the post-tensioning and prestressing technology and steps in bridges and building construction for civil work.

According to the regulations of CRCC(China Railways Production Certification Center)and CCPC(China Communications Certificate Center). The prestressing components need to by tested before leave factory and stressing equipment, especially for stressed jack and pump must be calibrated in factory or quality testing center.This can guarantee the materials, components, and pt equipment is qualified and good quality for bridge and buildings construction.

The following steps are how to install and operate stressed jack and pump for bridge and building construction

Step 1: Installation working anchor block, working wedges, anchor bearing plate. spiral reinforcing rings, if there is continuous beams it need to install multi-strands anchor coupler(include anchor coupler body, working wedges, anchorbearing plate, spiral spring rings, pocket former, constrain rings, dead end anchor)swages anchors).

Stressed end anchor installation

Step 2: After installation of stressed end anchor system, it need to install stressed jack and pump, then install stressing tools such as tooling anchor head, tooling wedges, and limited board, etc.

Usually, the tension force and pressure gauges will be calibrated in factory or local quality testing and inspection bureau.It vary from different prestressing projects, the operator should be strictly obey the tension regulation and must be careful in tesnion work in case happen accidents. Especially, the front of strands are forbidden stand any people. And must be marked"safety" principle around the worksite.

We manufacture stressed jack and pump for monostrand stressing(from 10 tons to 30 tons, suitable for tensioning single strand 12.7mm diameter and 15.24mm diameter pc strand), and for multistrands stressing( from 30 tons to 1200 tons, suitable for 15.24mm and 12.7mm 2 nos of pc strands to 55 nos pc strands).

Standard Type Multi-strands Stressing Jack and Pump

But in modern stressing work,we have developed new technology, it is intelligent tension machine. Use this intelligent tension system it can be more precise, more safe, and more efficient in tension work. Because all operation is controlled by computer, and one person can manage all process. It have been save most much labour, and this technol and equipment have been widely used in high speed railway, railway, highway, and big over-span bridge construction, etc. If you have any interest kindly please contact with us(email: sales@pt-concrete.com).

About Buildings Construction in Japan

In Japan, Building Standard Act has been strictly reviewed every time we experienced a large earthquake.

All buildings are strictly required to have an earthquake resistance structure. Without rigorous compliance to earthquake proof standard set by a low, one can never get an approval of construction of a building from a public administration office in Japan.

It is said that the collapse ratio of the building as a result of a powerful earthquake is extremely low in Japan compared to any other countries.

Prestressed concrete (PC) technology is being used all over the world in the construction of a wide range of bridge structures. However, many PC bridges have been deteriorating even before the end of their design service-life due to corrosion and other environmental effects. In view of this, a number of innovative technologies have been developed in Japan to increase not only the structural performance of PC bridges, but also their long-term durability. These include the development of novel structural systems and the advancement in construction materials. This paper presents an overview of such innovative technologies on PC bridges on their development and applications in actual construction projects. Some noteworthy structures, which represent the state-of-the-art technologies in the construction of PC bridges in Japan, are also presented. 

Precast, prestressed concrete construction method is environment-friendly and materializes ideals of architecture by streamlining the construction process.
