As a result of recent technological developments in the structural post tensioning industry, the production of ground anchors with a very high capacity is possible. The use of strand anchors in rock and soil anchor applications has become a well respected tool in the geotechnical engineer’s arsenal of solutions. By utilizing the combined load carrying capacity of multiple 0.6 inch diameter prestressing steel strands, loads which greatly exceed the tensile strength of any single bar can be achieved.

Strand anchors can be produced in extremely long lengths. For instance, strand anchors measuring anywhere from 100 to 200 feet in length can be assembled, coiled and banded in one of our manufacturing locations and shipped on wooden pallets via conventional flat-bed trucks.

In addition, many of the strand anchors used in temporary excavation support consist of seven strands or less. These anchors can often be uncoiled and installed by hand. Strand anchors also generally require much less site storage space and handling than bar anchors. We offer customized strand anchor manufacturing which allows for the design to be optimized in terms of both load carrying capacity and geometry to meet the requirements of specific site conditions.

Article 8: Equipment and Components for Buildings and Bridges Construction

Article 8: Equipment and Components for Buildings and Bridges Construction

Following my last article 7, this article is mainly introduce last steps of making bridges girder and concrete slab in buildings and bridge construction. Henan Prestressing Equipment Co., Limited supply full complete post tension components, materials and post tension equipment for buildings and bridge construction. Kindly please contact with us by our official email: sales@pt-concrete.com, or jason@pt-concrete.com, or call us: Mobile ＆WhattsApp(WeChat)Num.+8613673713569.

In bridge girder making process, we usually use dismountable metal frame moulds. Making prestresing foundation bed on bottom, and sides concrete slabs are symmetric distributed two sides. The cap was made by steel bar and poured concrete.

After the poured concrete is reached certain strength,the outside steel mould can be removed.

After removing steel mould the bridge girder should be keep moisture and goods maintenance until it reach the certain designed strength.

Stressed End Anchor System and Dead End Anchor System in Post-tension technology for bridge girder making

Henan Prestressing Equipment Co., Limited manufacture full ranges of anchor system such as multistrands round anchor, multistrands flat anchor, arch type anchor for buildings, monostrand anchor, ground anchor, spring loaded anchors, prestressed anchor coupler, single strand anchor coupler, steel bar anchor, dead end anchor, and other customized anchor according to your drawings.

We welcome to your visiting and inquiry! If you have any interest kindly please contact with us: official email: sales@pt-concrete.com, or jason@pt-concrete.com, or call us: Mobile ＆WhattsApp(WeChat)Num.+8613673713569.

Traditional grouting pump and mixer machine used for bridge girder construction

Before grouting, the grout must be tested and inspected by inspector.

One side of bridge girder is installed the one-way valve and the other side installed input pipes of grouting pump for grouting

Screw type grouting pump and mixer machine

Cutting the rested pc strand than sealing anchor with concrete and flatten concrete surface. Install one-way valve, waiting to vacuumize.

On the other side it need also install one-way valve to connect with vacuum pump

The following is brief introduction of our new generation intelligent grouting pump for prestressing and post-tension grouting work.

Intelligent Construction Grouting Equipment Concrete Machine

Intelligent grouting equipment adopts circular intelligent grouting system which is a new concept of "cicular grouting". It can eliminate the air completely out of the pipe, control the proportion of grout and water accurately, adjust the grouting pressure and time in time to ensure that the prestressed pipe grouting dense.

Features:

1. Automatic operation

2. High-speed mixing

3. Technology of anti-sediment in low-speed storage bucket

4. Easy moving

5. Continuous screw grouting system and prestressed vacuum system

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).
