Prestressing Equipment, Post-Tension Equipment and Stressed Equipment for Bridge and Buildings Construction

Henan Prestressing Equipment Co., Limited professionally manufacture prestressing and post-tensioning materials, component and pt equipment. The ranges of our prestressing and post-tensioning equipment are: monostrand jack and pump, multistrand jack and pump, bulbing jack(onion jack), duct making machine, duct flatten machine, dead end anchor making machine, strand pusher machine, grouting and mixer machine, and intelligent tension equipment. 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).

3. Introduction of Intelligent Automatic Tension Equipment System for Post-tension

Stressing is important in the prestressed construction of bridges and highways. However there are errors with stressing by humans which will affect the quality of construction. Intelligent stressing equipment is a kind of high technology which can guarantee the high quality of stressing with its accuracy and stability.

1. The intelligent stressing equipment can stress two or four jacks at the same time.

2. It can control the stressing force precisely which can collect the data of tension and add tension automatically.

3. The equipment can be operated conveniently with remote control system.

4. It can do intelligent data analysis and automatic report generation.

The main pump and vice pump with a wireless connection distance of not more than 200M. Vice pump displacement, pressure signal transmission to the main pump. The main pump will signal processing, the control signal will be transmitted to the vice pump, control the jack of oil, stop, return oil. Tensioning the construction site at the same time the main parameters of the site to stretch the parameters of the wireless transmission parameters to the site monitoring computer, and then by the site monitoring computer will pull the data uploaded to the company to establish a dedicated query site or self-built website, by entering the appropriate tensioning device number And Tension Date Query Download Tension Parameters. Or directly from the site monitoring computer to the owners of supervision. At the same time the main pump control module can store about 40000 of the tensile data to prevent transmission problems caused by the loss of tension parameters.
